+# wpa_supplicant depends on strong random number generation being available
+# from the operating system. os_get_random() function is used to fetch random
+# data when needed, e.g., for key generation. On Linux and BSD systems, this
+# works by reading /dev/urandom. It should be noted that the OS entropy pool
+# needs to be properly initialized before wpa_supplicant is started. This is
+# important especially on embedded devices that do not have a hardware random
+# number generator and may by default start up with minimal entropy available
+# for random number generation.
+#
+# As a safety net, wpa_supplicant is by default trying to internally collect
+# additional entropy for generating random data to mix in with the data fetched
+# from the OS. This by itself is not considered to be very strong, but it may
+# help in cases where the system pool is not initialized properly. However, it
+# is very strongly recommended that the system pool is initialized with enough
+# entropy either by using hardware assisted random number generator or by
+# storing state over device reboots.
+#
+# wpa_supplicant can be configured to maintain its own entropy store over
+# restarts to enhance random number generation. This is not perfect, but it is
+# much more secure than using the same sequence of random numbers after every
+# reboot. This can be enabled with -e<entropy file> command line option. The
+# specified file needs to be readable and writable by wpa_supplicant.
+#
+# If the os_get_random() is known to provide strong random data (e.g., on
+# Linux/BSD, the board in question is known to have reliable source of random

+Contributions to hostap.git
+---------------------------
+
+This software is distributed under a permissive open source license to
+allow it to be used in any projects, whether open source or proprietary.
+Contributions to the project are welcome and it is important to maintain
+clear record of contributions and terms under which they are licensed.
+To help with this, following procedure is used to allow acceptance and
+recording of the terms.
+
+These terms are similar to the process used in Linux kernel development.
+The items (a) through (d) are identical to the Developer's Certificate
+of Origin 1.1. To enable cleaner licensing option to be provided in the
+future, an additional item (e) is included.
+
+Until February 11, 2012, in case of most files in hostap.git, "under the
+open source license indicated in the file" means that the contribution
+is licensed both under GPL v2 and modified BSD license (see below) and
+the choice between these licenses is given to anyone who redistributes
+or uses the software. As such, the contribution has to be licensed under
+both options to allow this choice.
+
+As of February 11, 2012, the project has chosen to use only the BSD
+license option for future distribution. As such, the GPL v2 license
+option is no longer used and the contributions are not required to be
+licensed until GPL v2. In case of most files in hostap.git, "under the
+open source license indicated in the file" means that the contribution
+is licensed under the modified BSD license (see below).
+
+
+The additional item (e) is used to collect explicit approval to license
+the contribution with only the modified BSD license (see below), i.e.,
+without the GPL v2 option. This was done to allow simpler licensing
+terms to be used in the future. It should be noted that the modified BSD
+license is compatible with GNU GPL and as such, this possible move to
+simpler licensing option does not prevent use of this software in
+GPL projects.
+
+
+By making a contribution to this project, I certify that:
+
+(a) The contribution was created in whole or in part by me and I
+    have the right to submit it under the open source license
+    indicated in the file; or
+
+(b) The contribution is based upon previous work that, to the best
+    of my knowledge, is covered under an appropriate open source
+    license and I have the right under that license to submit that
+    work with modifications, whether created in whole or in part
+    by me, under the same open source license (unless I am
+    permitted to submit under a different license), as indicated
+    in the file; or
+
+(c) The contribution was provided directly to me by some other
+    person who certified (a), (b) or (c) and I have not modified
+    it.
+
+(d) I understand and agree that this project and the contribution
+    are public and that a record of the contribution (including all
+    personal information I submit with it, including my sign-off) is
+    maintained indefinitely and may be redistributed consistent with
+    this project or the open source license(s) involved.
+
+Additionally, I certify that:
+
+(e) The contribution can be licensed under the modified BSD license
+    as shown below even in case of files that are currently licensed
+    under other terms.
+
+
+To indicate your acceptance of these terms, please add the following
+line to each contribution you make to the project:

+
+using your real name. Pseudonyms or anonymous contributions cannot
+unfortunately be accepted.

+
+These programs are licensed under the BSD license (the one with
+advertisement clause removed).

+
+
+This package may include either wpa_supplicant, hostapd, or both. See
+README file respective subdirectories (wpa_supplicant/README or
+hostapd/README) for more details.
+
+Source code files were moved around in v0.6.x releases and compared to
+earlier releases, the programs are now built by first going to a
+subdirectory (wpa_supplicant or hostapd) and creating build
+configuration (.config) and running 'make' there (for Linux/BSD/cygwin
+builds).

+\ref tls_func "TLS library" |
+\ref configuration "Configuration" |

+\ref wpa_code "WPA supplicant" |
+\ref eap_peer "EAP peer" |
+\ref eapol_supp "EAPOL supplicant" |
+\ref win_port "Windows port" |
+\ref test_programs "Test programs" ]
+
+%wpa_supplicant implementation is divided into number of independent
+modules. Core code includes functionality for controlling the network
+selection, association, and configuration. Independent modules include
+WPA code (key handshake, PMKSA caching, pre-authentication), EAPOL
+state machine, and EAP state machine and methods. In addition, there
+are number of separate files for generic helper functions.
+
+Both WPA and EAPOL/EAP state machines can be used separately in other
+programs than %wpa_supplicant. As an example, the included test
+programs eapol_test and preauth_test are using these modules.
+
+\ref driver_wrapper "Driver interface API" is defined in driver.h and
+all hardware/driver dependent functionality is implemented in
+driver_*.c.
+
+
+\section _wpa_supplicant_core wpa_supplicant core functionality
+
+wpa_supplicant.c
+	Program initialization, main control loop
+
+main.c
+	main() for UNIX-like operating systems and MinGW (Windows); this

+
+events.c
+	Driver event processing; wpa_supplicant_event() and related functions
+
+wpa_supplicant_i.h
+	Internal definitions for %wpa_supplicant core; should not be
+	included into independent modules
+
+
+\section generic_helper_func Generic helper functions
+
+%wpa_supplicant uses generic helper functions some of which are shared
+with with hostapd. The following C files are currently used:

+	and wrappers for libdnet/libpcap). A new l2_packet implementation
+	may need to be added when porting to new operating systems that are
+	not supported by libdnet/libpcap. Makefile can be used to select which
+	l2_packet implementation is included. l2_packet_linux.c uses Linux
+	packet sockets and l2_packet_pcap.c has a more portable version using
+	libpcap and libdnet.
+
+pcsc_funcs.c and pcsc_funcs.h
+	Wrapper for PC/SC lite SIM and smart card readers
+
+priv_netlink.h
+	Private version of netlink definitions from Linux kernel header files;

+\page ctrl_iface_page %wpa_supplicant control interface
+
+%wpa_supplicant implements a control interface that can be used by
+external programs to control the operations of the %wpa_supplicant
+daemon and to get status information and event notifications. There is
+a small C library, in a form of a single C file, wpa_ctrl.c, that
+provides helper functions to facilitate the use of the control
+interface. External programs can link this file into them and then use
+the library functions documented in wpa_ctrl.h to interact with
+%wpa_supplicant. This library can also be used with C++. wpa_cli.c and
+wpa_gui are example programs using this library.
+
+There are multiple mechanisms for inter-process communication. For
+example, Linux version of %wpa_supplicant is using UNIX domain sockets
+for the control interface and Windows version UDP sockets. The use of
+the functions defined in wpa_ctrl.h can be used to hide the details of
+the used IPC from external programs.
+
+
+\section using_ctrl_iface Using the control interface
+
+External programs, e.g., a GUI or a configuration utility, that need to
+communicate with %wpa_supplicant should link in wpa_ctrl.c. This
+allows them to use helper functions to open connection to the control
+interface with wpa_ctrl_open() and to send commands with
+wpa_ctrl_request().
+
+%wpa_supplicant uses the control interface for two types of communication:
+commands and unsolicited event messages. Commands are a pair of
+messages, a request from the external program and a response from
+%wpa_supplicant. These can be executed using wpa_ctrl_request().
+Unsolicited event messages are sent by %wpa_supplicant to the control
+interface connection without specific request from the external program
+for receiving each message. However, the external program needs to
+attach to the control interface with wpa_ctrl_attach() to receive these
+unsolicited messages.
+
+If the control interface connection is used both for commands and
+unsolicited event messages, there is potential for receiving an
+unsolicited message between the command request and response.
+wpa_ctrl_request() caller will need to supply a callback, msg_cb,
+for processing these messages. Often it is easier to open two
+control interface connections by calling wpa_ctrl_open() twice and
+then use one of the connections for commands and the other one for
+unsolicited messages. This way command request/response pairs will
+not be broken by unsolicited messages. wpa_cli is an example of how
+to use only one connection for both purposes and wpa_gui demonstrates
+how to use two separate connections.
+
+Once the control interface connection is not needed anymore, it should
+be closed by calling wpa_ctrl_close(). If the connection was used for
+unsolicited event messages, it should be first detached by calling
+wpa_ctrl_detach().
+
+
+\section ctrl_iface_cmds Control interface commands
+
+Following commands can be used with wpa_ctrl_request():
+
+\subsection ctrl_iface_PING PING
+
+This command can be used to test whether %wpa_supplicant is replying
+to the control interface commands. The expected reply is \c PONG if the
+connection is open and %wpa_supplicant is processing commands.
+
+

+\endverbatim
+
+
+
+\subsection ctrl_iface_SELECT_NETWORK SELECT_NETWORK <network id>
+
+Select a network (disable others). Network id can be received from the
+\c LIST_NETWORKS command output.
+
+
+\subsection ctrl_iface_ENABLE_NETWORK ENABLE_NETWORK <network id>
+
+Enable a network. Network id can be received from the
+\c LIST_NETWORKS command output. Special network id \c all can be
+used to enable all network.
+
+
+\subsection ctrl_iface_DISABLE_NETWORK DISABLE_NETWORK <network id>
+
+Disable a network. Network id can be received from the
+\c LIST_NETWORKS command output. Special network id \c all can be
+used to disable all network.
+
+
+\subsection ctrl_iface_ADD_NETWORK ADD_NETWORK
+
+Add a new network. This command creates a new network with empty
+configuration. The new network is disabled and once it has been
+configured it can be enabled with \c ENABLE_NETWORK command. \c ADD_NETWORK
+returns the network id of the new network or FAIL on failure.
+
+
+\subsection ctrl_iface_REMOVE_NETWORK REMOVE_NETWORK <network id>
+
+Remove a network. Network id can be received from the
+\c LIST_NETWORKS command output. Special network id \c all can be
+used to remove all network.
+
+
+\subsection ctrl_iface_SET_NETWORK SET_NETWORK <network id> <variable> <value>
+
+Set network variables. Network id can be received from the
+\c LIST_NETWORKS command output.
+
+This command uses the same variables and data formats as the
+configuration file. See example wpa_supplicant.conf for more details.
+
+- ssid (network name, SSID)
+- psk (WPA passphrase or pre-shared key)
+- key_mgmt (key management protocol)
+- identity (EAP identity)
+- password (EAP password)
+- ...
+
+
+\subsection ctrl_iface_GET_NETWORK GET_NETWORK <network id> <variable>
+
+Get network variables. Network id can be received from the
+\c LIST_NETWORKS command output.
+
+
+\subsection ctrl_iface_SAVE_CONFIG SAVE_CONFIG
+
+Save the current configuration.
+
+
+\subsection ctrl_iface_P2P_FIND P2P_FIND
+
+Start P2P device discovery. Optional parameter can be used to specify
+the duration for the discovery in seconds (e.g., "P2P_FIND 5"). If the
+duration is not specified, discovery will be started for indefinite
+time, i.e., until it is terminated by P2P_STOP_FIND or P2P_CONNECT (to
+start group formation with a discovered peer).
+
+The default search type is to first run a full scan of all channels
+and then continue scanning only social channels (1, 6, 11). This
+behavior can be changed by specifying a different search type: social
+(e.g., "P2P_FIND 5 type=social") will skip the initial full scan and
+only search social channels; progressive (e.g., "P2P_FIND
+type=progressive") starts with a full scan and then searches
+progressively through all channels one channel at the time with the
+social channel scans. Progressive device discovery can be used to find
+new groups (and groups that were not found during the initial scan,
+e.g., due to the GO being asleep) over time without adding
+considerable extra delay for every Search state round.
+
+
+\subsection ctrl_iface_P2P_STOP_FIND P2P_STOP_FIND
+
+Stop ongoing P2P device discovery or other operation (connect, listen
+mode).
+
+
+\subsection ctrl_iface_P2P_CONNECT P2P_CONNECT
+
+Start P2P group formation with a discovered P2P peer. This includes
+group owner negotiation, group interface setup, provisioning, and
+establishing data connection.
+
+P2P_CONNECT <peer device address> <pbc|pin|PIN#>
+[label|display|keypad] [persistent] [join|auth] [go_intent=<0..15>]
+
+Start P2P group formation with a discovered P2P peer. This includes
+optional group owner negotiation, group interface setup, provisioning,
+and establishing data connection.
+
+The <pbc|pin|PIN#> parameter specifies the WPS provisioning
+method. "pbc" string starts pushbutton method, "pin" string start PIN
+method using an automatically generated PIN (which will be returned as
+the command return code), PIN# means that a pre-selected PIN can be
+used (e.g., 12345670). [label|display|keypad] is used with PIN method
+to specify which PIN is used (label=PIN from local label,
+display=dynamically generated random PIN from local display,
+keypad=PIN entered from peer device label or display). "persistent"
+parameter can be used to request a persistent group to be formed.
+
+"join" indicates that this is a command to join an existing group as a
+client. It skips the GO Negotiation part.
+
+"auth" indicates that the WPS parameters are authorized for the peer
+device without actually starting GO Negotiation (i.e., the peer is
+expected to initiate GO Negotiation). This is mainly for testing
+purposes.
+
+The optional "go_intent" parameter can be used to override the default
+GO Intent value.
+
+
+\subsection ctrl_iface_P2P_LISTEN P2P_LISTEN
+
+Start Listen-only state. Optional parameter can be used to specify the
+duration for the Listen operation in seconds. This command may not
+be of that much use during normal operations and is mainly designed
+for testing. It can also be used to keep the device discoverable
+without having to maintain a group.
+
+
+\subsection ctrl_iface_P2P_GROUP_REMOVE P2P_GROUP_REMOVE
+
+Terminate a P2P group. If a new virtual network interface was used for
+the group, it will also be removed. The network interface name of the
+group interface is used as a parameter for this command.
+
+
+\subsection ctrl_iface_P2P_GROUP_ADD P2P_GROUP_ADD
+
+Set up a P2P group owner manually (i.e., without group owner
+negotiation with a specific peer). This is also known as autonomous
+GO. Optional persistent=<network id> can be used to specify restart of
+a persistent group.
+
+
+\subsection ctrl_iface_P2P_PROV_DISC P2P_PROV_DISC
+
+Send P2P provision discovery request to the specified peer. The
+parameters for this command are the P2P device address of the peer and
+the desired configuration method. For example, "P2P_PROV_DISC
+02:01:02:03:04:05 display" would request the peer to display a PIN for
+us and "P2P_PROV_DISC 02:01:02:03:04:05 keypad" would request the peer
+to enter a PIN that we display.
+
+
+\subsection ctrl_iface_P2P_GET_PASSPHRASE P2P_GET_PASSPHRASE
+
+Get the passphrase for a group (only available when acting as a GO).
+
+
+\subsection ctrl_iface_P2P_SERV_DISC_REQ P2P_SERV_DISC_REQ
+
+Schedule a P2P service discovery request. The parameters for this
+command are the device address of the peer device (or 00:00:00:00:00:00
+for wildcard query that is sent to every discovered P2P peer that
+supports service discovery) and P2P Service Query TLV(s) as hexdump.
+For example, "P2P_SERV_DISC_REQ 00:00:00:00:00:00 02000001" schedules
+a request for listing all supported service discovery protocols and
+requests this to be sent to all discovered peers. The pending requests
+are sent during device discovery (see \ref ctrl_iface_P2P_FIND).
+
+This command returns an identifier for the pending query (e.g.,
+"1f77628") that can be used to cancel the request. Directed requests
+will be automatically removed when the specified peer has replied to
+it.
+
+
+\subsection ctrl_iface_P2P_SERV_DISC_CANCEL_REQ P2P_SERV_DISC_CANCEL_REQ
+
+Cancel a pending P2P service discovery request. This command takes a
+single parameter: identifier for the pending query (the value returned
+by \ref ctrl_iface_P2P_SERV_DISC_REQ), e.g.,
+"P2P_SERV_DISC_CANCEL_REQ 1f77628".
+
+
+\subsection ctrl_iface_P2P_SERV_DISC_RESP P2P_SERV_DISC_RESP
+
+Reply to a service discovery query. This command takes following
+parameters: frequency in MHz, destination address, dialog token,
+response TLV(s). The first three parameters are copied from the
+request event. For example,
+"P2P_SERV_DISC_RESP 2437 02:40:61:c2:f3:b7 1 0300000101".
+
+
+\subsection ctrl_iface_P2P_SERVICE_UPDATE P2P_SERVICE_UPDATE
+
+Indicate that local services have changed. This is used to increment
+the P2P service indicator value so that peers know when previously
+cached information may have changed.
+
+
+\subsection ctrl_iface_P2P_SERV_DISC_EXTERNAL P2P_SERV_DISC_EXTERNAL
+
+Configure external processing of P2P service requests: 0 (default) =
+no external processing of requests (i.e., internal code will reject
+each request), 1 = external processing of requests (external program
+is responsible for replying to service discovery requests with
+\ref ctrl_iface_P2P_SERV_DISC_RESP).
+
+
+\subsection ctrl_iface_P2P_REJECT P2P_REJECT
+
+Reject connection attempt from a peer (specified with a device
+address). This is a mechanism to reject a pending GO Negotiation with
+a peer and request to automatically block any further connection or
+discovery of the peer.
+
+
+\subsection ctrl_iface_P2P_INVITE P2P_INVITE
+
+Invite a peer to join a group or to (re)start a persistent group.
+
+
+\subsection ctrl_iface_P2P_PEER P2P_PEER
+
+Fetch information about a discovered peer. This command takes in an
+argument specifying which peer to select: P2P Device Address of the
+peer, "FIRST" to indicate the first peer in the list, or "NEXT-<P2P
+Device Address>" to indicate the entry following the specified peer
+(to allow for iterating through the list).
+
+
+\subsection ctrl_iface_P2P_EXT_LISTEN P2P_EXT_LISTEN
+
+Enable/disable extended listen timing. Without parameters, this
+command disables extended listen timing. When enabling the feature,
+two parameters are used: availibility period and availability interval
+(both in milliseconds and with range of 1-65535).
+
+
+\section ctrl_iface_interactive Interactive requests
+
+If %wpa_supplicant needs additional information during authentication
+(e.g., password), it will use a specific prefix, \c CTRL-REQ-
+(\a WPA_CTRL_REQ macro) in an unsolicited event message. An external
+program, e.g., a GUI, can provide such information by using
+\c CTRL-RSP- (\a WPA_CTRL_RSP macro) prefix in a command with matching
+field name.
+
+The following fields can be requested in this way from the user:
+- IDENTITY (EAP identity/user name)
+- PASSWORD (EAP password)
+- NEW_PASSWORD (New password if the server is requesting password change)
+- PIN (PIN code for accessing a SIM or smartcard)
+- OTP (one-time password; like password, but the value is used only once)
+- PASSPHRASE (passphrase for a private key file)
+
+\verbatim
+CTRL-REQ-<field name>-<network id>-<human readable text>
+CTRL-RSP-<field name>-<network id>-<value>
+\endverbatim
+
+For example, request from %wpa_supplicant:
+\verbatim
+CTRL-REQ-PASSWORD-1-Password needed for SSID test-network
+\endverbatim
+
+And a matching reply from the GUI:
+\verbatim
+CTRL-RSP-PASSWORD-1-secret
+\endverbatim
+
+
+\subsection ctrl_iface_GET_CAPABILITY GET_CAPABILITY <option> [strict]

+\section ctrl_iface_events Control interface events
+
+%wpa_supplicant generates number messages based on events like
+connection or a completion of a task. These are available to external
+programs that attach to receive unsolicited messages over the control
+interface with wpa_ctrl_attach().
+
+The event messages will be delivered over the attach control interface
+as text strings that start with the priority level of the message and
+a fixed prefix text as defined in wpa_ctrl.h. After this, optional
+additional information may be included depending on the event
+message. For example, following event message is delivered when new
+scan results are available:
+
+\verbatim
+<2>CTRL-EVENT-SCAN-RESULTS
+\endverbatim
+
+Following priority levels are used:
+- 0 = MSGDUMP
+- 1 = DEBUG
+- 2 = INFO
+- 3 = WARNING
+- 4 = ERROR
+
+By default, any priority level greater than equal to 2 (INFO) are
+delivered over the attached control interface. LEVEL command can be
+used to set the level of messages which will be delivered. It should
+be noted that there are many debug messages that do not include any
+particulat prefix and are subject to change. They may be used for
+debug information, but can usually be ignored by external programs.
+
+In most cases, the external program can skip over the priority field
+in the beginning of the event message and then compare the following
+text to the event strings from wpa_ctrl.h that the program is
+interested in processing.
+
+Following subsections describe the most common event notifications
+generated by %wpa_supplicant.

+/**
+\page driver_wrapper Driver wrapper implementation (driver.h, drivers.c)
+
+All hardware and driver dependent functionality is in separate C files
+that implement defined wrapper functions. Other parts
+of the %wpa_supplicant are designed to be hardware, driver, and operating
+system independent.
+
+Driver wrappers need to implement whatever calls are used in the
+target operating system/driver for controlling wireless LAN
+devices. As an example, in case of Linux, these are mostly some glue
+code and ioctl() calls and netlink message parsing for Linux Wireless
+Extensions (WE). Since features required for WPA were added only recently to
+Linux Wireless Extensions (in version 18), some driver specific code is used
+in number of driver interface implementations. These driver dependent parts
+can be replaced with generic code in driver_wext.c once the target driver
+includes full support for WE-18. After that, all Linux drivers, at
+least in theory, could use the same driver wrapper code.
+
+A driver wrapper needs to implement some or all of the functions
+defined in driver.h. These functions are registered by filling struct
+wpa_driver_ops with function pointers. Hardware independent parts of
+%wpa_supplicant will call these functions to control the driver/wlan
+card. In addition, support for driver events is required. The event
+callback function, wpa_supplicant_event(), and its parameters are
+documented in driver.h. In addition, a pointer to the 'struct
+wpa_driver_ops' needs to be registered in drivers.c file.
+
+When porting to other operating systems, the driver wrapper should be
+modified to use the native interface of the target OS. It is possible
+that some extra requirements for the interface between the driver
+wrapper and generic %wpa_supplicant code are discovered during porting
+to a new operating system. These will be addressed on case by case
+basis by modifying the interface and updating the other driver
+wrappers for this. The goal is to avoid changing this interface
+without very good reasons in order to limit the number of changes
+needed to other wrappers and hardware independent parts of
+%wpa_supplicant. When changes are required, recommended way is to
+make them in backwards compatible way that allows existing driver
+interface implementations to be compiled without any modification.
+
+Generic Linux Wireless Extensions functions are implemented in
+driver_wext.c. All Linux driver wrappers can use these when the kernel
+driver supports the generic ioctl()s and wireless events. Driver
+specific functions are implemented in separate C files, e.g.,
+driver_hostap.c. These files need to define struct wpa_driver_ops
+entry that will be used in wpa_supplicant.c when calling driver
+functions. struct wpa_driver_ops entries are registered in drivers.c.
+
+In general, it is likely to be useful to first take a look at couple
+of driver interface examples before starting on implementing a new
+one. driver_hostap.c and driver_wext.c include a complete
+implementation for Linux drivers that use %wpa_supplicant-based control
+of WPA IE and roaming. driver_ndis.c (with help from driver_ndis_.c)
+is an example of a complete interface for Windows NDIS interface for
+drivers that generate WPA IE themselves and decide when to roam. These
+example implementations include full support for all security modes.
+
+
+\section driver_req Driver requirements for WPA
+
+WPA introduces new requirements for the device driver. At least some
+of these need to be implemented in order to provide enough support for
+%wpa_supplicant.
+
+\subsection driver_tkip_ccmp TKIP/CCMP
+
+WPA requires that the pairwise cipher suite (encryption algorithm for
+unicast data packets) is TKIP or CCMP. These are new encryption
+protocols and thus, the driver will need to be modified to support
+them. Depending on the used wlan hardware, some parts of these may be
+implemented by the hardware/firmware.
+
+Specification for both TKIP and CCMP is available from IEEE (IEEE
+802.11i amendment). Fully functional, hardware independent
+implementation of both encryption protocols is also available in Host
+AP driver (driver/modules/hostap_{tkip,ccmp}.c). In addition, Linux 2.6
+kernel tree has generic implementations for WEP, TKIP, and CCMP that can
+be used in Linux drivers.
+
+The driver will also need to provide configuration mechanism to allow
+user space programs to configure TKIP and CCMP. Linux Wireless Extensions
+v18 added support for configuring these algorithms and
+individual/non-default keys. If the target kernel does not include WE-18,
+private ioctls can be used to provide similar functionality.
+
+\subsection driver_roaming Roaming control and scanning support
+
+%wpa_supplicant can optionally control AP selection based on the
+information received from Beacon and/or Probe Response frames
+(ap_scan=1 mode in configuration). This means that the driver should
+support external control for scan process. In case of Linux, use of
+new Wireless Extensions scan support (i.e., 'iwlist wlan0 scan') is
+recommended. The current driver wrapper (driver_wext.c) uses this for
+scan results.
+
+Scan results must also include the WPA information element. Support for
+this was added in WE-18. With older versions, a custom event can be used
+to provide the full WPA IE (including element id and length) as a hex
+string that is included in the scan results.
+
+%wpa_supplicant needs to also be able to request the driver to
+associate with a specific BSS. Current Host AP driver and matching
+driver_hostap.c wrapper uses following sequence for this
+request. Similar/identical mechanism should be usable also with other
+drivers.
+
+- set WPA IE for AssocReq with private ioctl
+- set SSID with SIOCSIWESSID
+- set channel/frequency with SIOCSIWFREQ
+- set BSSID with SIOCSIWAP
+  (this last ioctl will trigger the driver to request association)
+
+\subsection driver_wpa_ie WPA IE generation
+
+%wpa_supplicant selects which cipher suites and key management suites
+are used. Based on this information, it generates a WPA IE. This is
+provided to the driver interface in the associate call. This does not
+match with Windows NDIS drivers which generate the WPA IE
+themselves.
+
+%wpa_supplicant allows Windows NDIS-like behavior by providing the
+selected cipher and key management suites in the associate call. If
+the driver generates its own WPA IE and that differs from the one
+generated by %wpa_supplicant, the driver has to inform %wpa_supplicant
+about the used WPA IE (i.e., the one it used in (Re)Associate
+Request). This notification is done using EVENT_ASSOCINFO event (see
+driver.h). %wpa_supplicant is normally configured to use
+ap_scan=2 mode with drivers that control WPA IE generation and roaming.
+
+\subsection driver_events Driver events
+
+%wpa_supplicant needs to receive event callbacks when certain events
+occur (association, disassociation, Michael MIC failure, scan results
+available, PMKSA caching candidate). These events and the callback
+details are defined in driver.h (wpa_supplicant_event() function
+and enum wpa_event_type).
+
+On Linux, association and disassociation can use existing Wireless
+Extensions event that is reporting new AP with SIOCGIWAP
+event. Similarly, completion of a scan can be reported with SIOCGIWSCAN
+event.
+
+Michael MIC failure event was added in WE-18. Older versions of Wireless
+Extensions will need to use a custom event. Host AP driver used a custom
+event with following contents: MLME-MICHAELMICFAILURE.indication(keyid=#
+broadcast/unicast addr=addr2). This is the recommended format until
+the driver can be moved to use WE-18 mechanism.
+
+\subsection driver_wext_summary Summary of Linux Wireless Extensions use
+
+AP selection depends on ap_scan configuration:
+
+ap_scan=1:
+
+- %wpa_supplicant requests scan with SIOCSIWSCAN
+- driver reports scan complete with wireless event SIOCGIWSCAN
+- %wpa_supplicant reads scan results with SIOCGIWSCAN (multiple call if
+  a larget buffer is needed)
+- %wpa_supplicant decides which AP to use based on scan results
+- %wpa_supplicant configures driver to associate with the selected BSS
+  (SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWFREQ,
+   SIOCSIWESSID, SIOCSIWAP)
+
+ap_scan=2:
+
+- %wpa_supplicant configures driver to associate with an SSID
+  (SIOCSIWMODE, SIOCSIWGENIE, SIOCSIWAUTH, SIOCSIWESSID)
+
+
+After this, both modes use similar steps:
+
+- optionally (or required for drivers that generate WPA/RSN IE for
+  (Re)AssocReq), driver reports association parameters (AssocReq IEs)
+  with wireless event IWEVASSOCREQIE (and optionally IWEVASSOCRESPIE)
+- driver reports association with wireless event SIOCGIWAP
+- %wpa_supplicant takes care of EAPOL frame handling (validating
+  information from associnfo and if needed, from scan results if WPA/RSN
+  IE from the Beacon frame is not reported through associnfo)

+/**
+\page eap_peer_module EAP peer implementation
+
+Extensible Authentication Protocol (EAP) is an authentication framework
+defined in RFC 3748. %wpa_supplicant uses a separate code module for EAP
+peer implementation. This module was designed to use only a minimal set
+of direct function calls (mainly, to debug/event functions) in order for
+it to be usable in other programs. The design of the EAP
+implementation is based loosely on RFC 4137. The state machine is
+defined in this RFC and so is the interface between the peer state
+machine and methods. As such, this RFC provides useful information for
+understanding the EAP peer implementation in %wpa_supplicant.
+
+Some of the terminology used in EAP state machine is referring to
+EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
+layer being IEEE 802.1X if EAP module is built for other programs than
+%wpa_supplicant. These terms should be understood to refer to the
+lower layer as defined in RFC 4137.
+
+
+\section adding_eap_methods Adding EAP methods
+
+Each EAP method is implemented as a separate module, usually as one C
+file named eap_<name of the method>.c, e.g., eap_md5.c. All EAP
+methods use the same interface between the peer state machine and
+method specific functions. This allows new EAP methods to be added
+without modifying the core EAP state machine implementation.
+
+New EAP methods need to be registered by adding them into the build
+(Makefile) and the EAP method registration list in the
+eap_peer_register_methods() function of eap_methods.c. Each EAP
+method should use a build-time configuration option, e.g., EAP_TLS, in
+order to make it possible to select which of the methods are included
+in the build.
+
+EAP methods must implement the interface defined in eap_i.h. struct
+eap_method defines the needed function pointers that each EAP method
+must provide. In addition, the EAP type and name are registered using
+this structure. This interface is based on section 4.4 of RFC 4137.
+
+It is recommended that the EAP methods would use generic helper
+functions, eap_msg_alloc() and eap_hdr_validate() when processing
+messages. This allows code sharing and can avoid missing some of the
+needed validation steps for received packets. In addition, these
+functions make it easier to change between expanded and legacy EAP
+header, if needed.
+
+When adding an EAP method that uses a vendor specific EAP type
+(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
+must be registered by passing vendor id instead of EAP_VENDOR_IETF to
+eap_peer_method_alloc(). These methods must not try to emulate
+expanded types by registering a legacy EAP method for type 254. See
+eap_vendor_test.c for an example of an EAP method implementation that
+is implemented as an expanded type.
+
+
+\section used_eap_library Using EAP implementation as a library
+
+The Git repository has an eap_example directory that contains an
+example showing how EAP peer and server code from %wpa_supplicant and
+hostapd can be used as a library. The example program initializes both
+an EAP server and an EAP peer entities and then runs through an
+EAP-PEAP/MSCHAPv2 authentication.
+
+eap_example_peer.c shows the initialization and glue code needed to
+control the EAP peer implementation. eap_example_server.c does the
+same for EAP server. eap_example.c is an example that ties in both the
+EAP server and client parts to allow an EAP authentication to be
+shown.
+
+In this example, the EAP messages are passed between the server and
+the peer are passed by direct function calls within the same process.
+In practice, server and peer functionalities would likely reside in
+separate devices and the EAP messages would be transmitted between the
+devices based on an external protocol. For example, in IEEE 802.11
+uses IEEE 802.1X EAPOL state machines to control the transmission of
+EAP messages and WiMax supports optional PMK EAP authentication
+mechanism that transmits EAP messages as defined in IEEE 802.16e.
+
+The EAP library links in number of helper functions from src/utils and
+src/crypto directories. Most of these are suitable as-is, but it may
+be desirable to replace the debug output code in src/utils/wpa_debug.c
+by dropping this file from the library and re-implementing the
+functions there in a way that better fits in with the main
+application.

+/**
+\page eap_server_module EAP server implementation
+
+Extensible Authentication Protocol (EAP) is an authentication framework
+defined in RFC 3748. hostapd uses a separate code module for EAP server
+implementation. This module was designed to use only a minimal set of
+direct function calls (mainly, to debug/event functions) in order for
+it to be usable in other programs. The design of the EAP
+implementation is based loosely on RFC 4137. The state machine is
+defined in this RFC and so is the interface between the server state
+machine and methods. As such, this RFC provides useful information for
+understanding the EAP server implementation in hostapd.
+
+Some of the terminology used in EAP state machine is referring to
+EAPOL (IEEE 802.1X), but there is no strict requirement on the lower
+layer being IEEE 802.1X if EAP module is built for other programs than
+%wpa_supplicant. These terms should be understood to refer to the
+lower layer as defined in RFC 4137.
+
+
+\section adding_eap_methods Adding EAP methods
+
+Each EAP method is implemented as a separate module, usually as one C
+file named eap_<name of the method>.c, e.g., eap_md5.c. All EAP
+methods use the same interface between the server state machine and
+method specific functions. This allows new EAP methods to be added
+without modifying the core EAP state machine implementation.
+
+New EAP methods need to be registered by adding them into the build
+(Makefile) and the EAP method registration list in the
+eap_server_register_methods() function of eap_methods.c. Each EAP
+method should use a build-time configuration option, e.g., EAP_TLS, in
+order to make it possible to select which of the methods are included
+in the build.
+
+EAP methods must implement the interface defined in eap_i.h. struct
+eap_method defines the needed function pointers that each EAP method
+must provide. In addition, the EAP type and name are registered using
+this structure. This interface is based on section 4.4 of RFC 4137.
+
+It is recommended that the EAP methods would use generic helper
+functions, eap_msg_alloc() and eap_hdr_validate() when processing
+messages. This allows code sharing and can avoid missing some of the
+needed validation steps for received packets. In addition, these
+functions make it easier to change between expanded and legacy EAP
+header, if needed.
+
+When adding an EAP method that uses a vendor specific EAP type
+(Expanded Type as defined in RFC 3748, Chapter 5.7), the new method
+must be registered by passing vendor id instead of EAP_VENDOR_IETF to
+eap_server_method_alloc(). These methods must not try to emulate
+expanded types by registering a legacy EAP method for type 254. See
+eap_vendor_test.c for an example of an EAP method implementation that
+is implemented as an expanded type.

+/**
+\page hostapd_ctrl_iface_page hostapd control interface
+
+hostapd implements a control interface that can be used by
+external programs to control the operations of the hostapd
+daemon and to get status information and event notifications. There is
+a small C library, in a form of a single C file, wpa_ctrl.c, that
+provides helper functions to facilitate the use of the control
+interface. External programs can link this file into them and then use
+the library functions documented in wpa_ctrl.h to interact with
+%wpa_supplicant. This library can also be used with C++. hostapd_cli.c
+is an example program using this library.
+
+There are multiple mechanisms for inter-process communication. For
+example, Linux version of hostapd is using UNIX domain sockets for the
+control interface. The use of the functions defined in wpa_ctrl.h can
+be used to hide the details of the used IPC from external programs.
+
+
+\section using_ctrl_iface Using the control interface
+
+External programs, e.g., a GUI or a configuration utility, that need to
+communicate with hostapd should link in wpa_ctrl.c. This
+allows them to use helper functions to open connection to the control
+interface with wpa_ctrl_open() and to send commands with
+wpa_ctrl_request().
+
+hostapd uses the control interface for two types of communication:
+commands and unsolicited event messages. Commands are a pair of
+messages, a request from the external program and a response from
+hostapd. These can be executed using wpa_ctrl_request().
+Unsolicited event messages are sent by hostapd to the control
+interface connection without specific request from the external program
+for receiving each message. However, the external program needs to
+attach to the control interface with wpa_ctrl_attach() to receive these
+unsolicited messages.
+
+If the control interface connection is used both for commands and
+unsolicited event messages, there is potential for receiving an
+unsolicited message between the command request and response.
+wpa_ctrl_request() caller will need to supply a callback, msg_cb,
+for processing these messages. Often it is easier to open two
+control interface connections by calling wpa_ctrl_open() twice and
+then use one of the connections for commands and the other one for
+unsolicited messages. This way command request/response pairs will
+not be broken by unsolicited messages. wpa_cli is an example of how
+to use only one connection for both purposes and wpa_gui demonstrates
+how to use two separate connections.
+
+Once the control interface connection is not needed anymore, it should
+be closed by calling wpa_ctrl_close(). If the connection was used for
+unsolicited event messages, it should be first detached by calling
+wpa_ctrl_detach().
+
+
+\section ctrl_iface_cmds Control interface commands
+
+Following commands can be used with wpa_ctrl_request():
+
+\subsection ctrl_iface_PING PING
+
+This command can be used to test whether hostapd is replying
+to the control interface commands. The expected reply is \c PONG if the
+connection is open and hostapd is processing commands.

+\mainpage Developers' documentation for wpa_supplicant and hostapd
+
+The goal of this documentation and comments in the source code is to
+give enough information for other developers to understand how
+%wpa_supplicant and hostapd have been implemented, how they can be
+modified, how new drivers can be supported, and how the source code
+can be ported to other operating systems. If any information is
+missing, feel free to contact Jouni Malinen <j@w1.fi> for more
+information. Contributions as patch files are also very welcome at the
+same address. Please note that this software is licensed under the
+BSD license (the one with advertisement clause removed). All
+contributions to %wpa_supplicant and hostapd are expected to use
+compatible licensing terms.
+
+The source code and read-only access to the combined %wpa_supplicant
+and hostapd Git repository is available from the project home page at
+http://w1.fi/wpa_supplicant/. This developers' documentation is also
+available as a PDF file from
+http://w1.fi/wpa_supplicant/wpa_supplicant-devel.pdf .
+
+
+\section _wpa_supplicant wpa_supplicant
+
+%wpa_supplicant is a WPA Supplicant for Linux, BSD and Windows with
+support for WPA and WPA2 (IEEE 802.11i / RSN). Supplicant is the IEEE
+802.1X/WPA component that is used in the client stations. It
+implements key negotiation with a WPA Authenticator and it can optionally
+control roaming and IEEE 802.11 authentication/association of the wlan
+driver.
+
+The design goal for %wpa_supplicant was to use hardware, driver, and
+OS independent, portable C code for all WPA functionality. The source
+code is divided into separate C files as shown on the \ref
+code_structure "code structure page". All hardware/driver specific
+functionality is in separate files that implement a \ref
+driver_wrapper "well-defined driver API". Information about porting
+to different target boards and operating systems is available on
+the \ref porting "porting page".
+
+EAPOL (IEEE 802.1X) state machines are implemented as a separate
+module that interacts with \ref eap_peer_module "EAP peer implementation".
+In addition to programs aimed at normal production use,
+%wpa_supplicant source tree includes number of \ref testing_tools
+"testing and development tools" that make it easier to test the
+programs without having to setup a full test setup with wireless
+cards. These tools can also be used to implement automatic test
+suites.
+
+%wpa_supplicant implements a
+\ref ctrl_iface_page "control interface" that can be used by
+external programs to control the operations of the %wpa_supplicant
+daemon and to get status information and event notifications. There is
+a small C library that provides helper functions to facilitate the use of the
+control interface. This library can also be used with C++.

+\section _hostapd hostapd
+
+hostapd includes IEEE 802.11 access point management (authentication /
+association), IEEE 802.1X/WPA/WPA2 Authenticator, EAP server, and
+RADIUS authentication server functionality. It can be build with
+various configuration option, e.g., a standalone AP management
+solution or a RADIUS authentication server with support for number of
+EAP methods.
+
+The design goal for hostapd was to use hardware, driver, and
+OS independent, portable C code for all WPA functionality. The source
+code is divided into separate C files as shown on the \ref
+code_structure "code structure page". All hardware/driver specific
+functionality is in separate files that implement a \ref
+driver_wrapper "well-defined driver API". Information about porting
+to different target boards and operating systems is available on
+the \ref porting "porting page".
+
+EAPOL (IEEE 802.1X) state machines are implemented as a separate
+module that interacts with \ref eap_server_module "EAP server implementation".
+Similarly, RADIUS authentication server is in its own separate module.
+Both IEEE 802.1X and RADIUS authentication server can use EAP server
+functionality.
+
+hostapd implements a \ref hostapd_ctrl_iface_page "control interface"
+that can be used by external programs to control the operations of the
+hostapdt daemon and to get status information and event notifications.
+There is a small C library that provides helper functions to facilitate
+the use of the control interface. This library can also be used with
+C++.

+\page p2p Wi-Fi Direct - P2P module
+
+Wi-Fi Direct functionality is implemented any many levels in the WLAN
+stack from low-level driver operations to high-level GUI design. This
+document covers the parts that can be user by %wpa_supplicant. However,
+it should be noted that alternative designs are also possible, so some
+of the functionality may reside in other components in the system.
+
+The driver (or WLAN firmware/hardware) is expected to handle low-level
+operations related to P2P Power Management and channel scheduling. In
+addition, support for virtual network interface and data frame
+processing is done inside the driver. Configuration for these
+low-level operations is defined in the driver interface:
+src/drivers/driver.h. This defines both the commands and events used to
+interact with the driver.
+
+P2P module implements higher layer functionality for management P2P
+groups. It takes care of Device Discovery, Service Discovery, Group
+Owner Negotiation, P2P Invitation. In addition, it maintains
+information about neighboring P2P Devices. This module could be used
+in designs that do not use %wpa_supplicant and it could also reside
+inside the driver/firmware component. P2P module API is defined in
+src/p2p/p2p.h.
+
+Provisioning step of Group Formation is implemented using WPS
+(src/wps/wps.h).
+
+%wpa_supplicant includes code in interact with both the P2P module
+(wpa_supplicant/p2p_supplicant.c) and WPS
+(wpa_supplicant/wps_supplicant.c). The driver operations are passed
+through these files, i.e., core P2P or WPS code does not interact
+directly with the driver interface.
+
+
+\section p2p_arch P2P architecture
+
+P2P functionality affects many areas of the system architecture. This
+section shows couple of examples on the location of main P2P
+components. In the diagrams below, green arrows are used to show
+communication paths from the P2P module to upper layer management
+functionality and all the way to a GUI that user could use to manage
+P2P connections. Blue arrows show the path taken for lower layer
+operations. Glue code is used to bind the P2P module API to the rest
+of the system to provide access both towards upper and lower layer
+functionality.
+
+\subsection p2p_arch_mac80211 P2P architecture with Linux/mac80211/ath9k
+
+An architecture where the P2P module resides inside the
+%wpa_supplicant process is used with Linux mac80211-based drivers,
+e.g., ath9k. The following diagram shows the main components related
+to P2P functionality in such an architecture.
+
+\image html p2p_arch.png "P2P module within wpa_supplicant"
+\image latex p2p_arch.eps "P2P module within wpa_supplicant" width=15cm
+
+\subsection p2p_arch_umac P2P architecture with UMAC
+
+The following diagram shows the main components related to P2P
+functionality in an architecture where the P2P module resides inside
+the kernel IEEE 802.11 stack (UMAC in the figure).
+

+
+
+\section p2p_module P2P module
+
+P2P module manages discovery and group formation with a single state
+machine, i.e., only a single operation per device can be in progress
+at any given time. The following diagram describes the P2P state
+machine. For clarity, it does not include state transitions on
+operation timeouts to the IDLE state. The states that are marked with
+dotted ellipse are listed for clarity to describe the protocol
+functionality for Device Discovery phase, but are not used in the
+implementation (the SEARCH state is used to manage the initial Scan
+and the alternating Listen and Search states within Find).
+

+\image latex p2p_sm.eps "P2P module state machine" width=15cm
+
+\subsection p2p_module_api P2P module API
+
+P2P module API is defined in src/p2p/p2p.h. The API consists of
+functions for requesting operations and for providing event
+notifications. Similar set of callback functions are configured with
+struct p2p_config to provide callback functions that P2P module can
+use to request operations and to provide event notifications. In
+addition, there are number of generic helper functions that can be
+used for P2P related operations.
+
+These are the main functions for an upper layer management entity to
+request P2P operations:
+- p2p_find()
+- p2p_stop_find()
+- p2p_listen()
+- p2p_connect()
+- p2p_reject()
+- p2p_prov_disc_req()
+- p2p_sd_request()
+- p2p_sd_cancel_request()
+- p2p_sd_response()
+- p2p_sd_service_update()
+- p2p_invite()
+
+These are the main callback functions for P2P module to provide event
+notifications to the upper layer management entity:
+
+- p2p_config::dev_found()
+- p2p_config::go_neg_req_rx()
+- p2p_config::go_neg_completed()
+- p2p_config::sd_request()
+- p2p_config::sd_response()
+- p2p_config::prov_disc_req()
+- p2p_config::prov_disc_resp()
+- p2p_config::invitation_process()
+- p2p_config::invitation_received()
+- p2p_config::invitation_result()
+
+The P2P module uses following functions to request lower layer driver
+operations:
+
+- p2p_config::p2p_scan()
+- p2p_config::send_probe_resp()
+- p2p_config::send_action()
+- p2p_config::send_action_done()
+- p2p_config::start_listen()
+- p2p_config::stop_listen()
+
+Events from lower layer driver operations are delivered to the P2P
+module with following functions:
+
+- p2p_probe_req_rx()
+- p2p_rx_action()
+- p2p_scan_res_handler()
+- p2p_scan_res_handled()
+- p2p_send_action_cb()
+- p2p_listen_cb()
+
+In addition to the per-device state, the P2P module maintains
+per-group state for group owners. This is initialized with a call to
+p2p_group_init() when a group is created and deinitialized with
+p2p_group_deinit(). The upper layer GO management entity uses
+following functions to interact with the P2P per-group state:
+
+- p2p_group_notif_assoc()
+- p2p_group_notif_disassoc()
+- p2p_group_notif_formation_done()
+- p2p_group_match_dev_type()
+
+The P2P module will use following callback function to update P2P IE
+for GO Beacon and Probe Response frames:
+
+- p2p_group_config::ie_update()
+
+
+\section p2p_driver P2P driver operations (low-level interface)
+
+The following driver wrapper functions are needed for P2P in addition
+to the standard station/AP mode operations when the P2P module resides
+within %wpa_supplicant:
+- wpa_driver_ops::if_add()
+- wpa_driver_ops::if_remove()
+- wpa_driver_ops::alloc_interface_addr()
+- wpa_driver_ops::release_interface_addr()
+- wpa_driver_ops::remain_on_channel()
+- wpa_driver_ops::cancel_remain_on_channel()
+- wpa_driver_ops::send_action()
+- wpa_driver_ops::probe_req_report()
+- wpa_driver_ops::disable_11b_rates()
+
+The following driver wrapper events are needed for P2P in addition to
+the standard station/AP mode events when the P2P module resides within
+%wpa_supplicant:
+- wpa_event_type::EVENT_RX_ACTION
+- wpa_event_type::EVENT_REMAIN_ON_CHANNEL
+- wpa_event_type::EVENT_CANCEL_REMAIN_ON_CHANNEL
+- wpa_event_type::EVENT_RX_PROBE_REQ
+
+The following driver wrapper functions are needed for P2P in addition
+to the standard station/AP mode operations when the P2P module resides
+in the driver or firmware:
+- wpa_driver_ops::if_add()
+- wpa_driver_ops::if_remove()
+- wpa_driver_ops::alloc_interface_addr()
+- wpa_driver_ops::release_interface_addr()
+- wpa_driver_ops::disable_11b_rates()
+- wpa_driver_ops::p2p_find()
+- wpa_driver_ops::p2p_stop_find()
+- wpa_driver_ops::p2p_listen()
+- wpa_driver_ops::p2p_connect()
+- wpa_driver_ops::p2p_reject()
+- wpa_driver_ops::wps_success_cb()
+- wpa_driver_ops::p2p_group_formation_failed()
+- wpa_driver_ops::p2p_set_params()
+
+The following driver wrapper events are needed for P2P in addition to
+the standard station/AP mode events when the P2P module resides in the
+driver or firmware:
+- wpa_event_type::EVENT_P2P_DEV_FOUND
+- wpa_event_type::EVENT_P2P_GO_NEG_REQ_RX
+- wpa_event_type::EVENT_P2P_GO_NEG_COMPLETED
+
+
+\section p2p_go_neg P2P device discovery and group formation
+
+This section shows an example sequence of operations that can be used
+to implement P2P device discovery and group formation. The function
+calls are described based on the P2P module API. The exact design for
+the glue code outside the P2P module depends on the architecture used
+in the system.
+
+An upper layer management entity starts P2P device discovery by
+calling p2p_find(). The P2P module start the discovery by requesting a
+full scan to be completed by calling p2p_config::p2p_scan(). Results
+from the scan will be reported by calling p2p_scan_res_handler() and
+after last result, the scan result processing is terminated with a
+call to p2p_scan_res_handled(). The P2P peers that are found during
+the full scan are reported with the p2p_config::dev_found() callback.
+
+After the full scan, P2P module start alternating between Listen and
+Search states until the device discovery operation times out or
+terminated, e.g., with a call to p2p_stop_find().
+
+When going into the Listen state, the P2P module requests the driver
+to be configured to be awake on the listen channel with a call to
+p2p_config::start_listen(). The glue code using the P2P module may
+implement this, e.g., by using remain-on-channel low-level driver
+functionality for off-channel operation. Once the driver is available
+on the requested channel, notification of this is delivered by calling
+p2p_listen_cb(). The Probe Request frames that are received during the
+Listen period are delivered to the P2P module by calling
+p2p_config::p2p_probe_req_rx() and P2P module request a response to
+these to be sent by using p2p_config::send_probe_resp() callback
+function. If a group owner negotiation from another P2P device is
+received during the device discovery phase, that is indicated to the
+upper layer code with the p2p_config::go_neg_req_tx() callback.
+
+The Search state is implemented by using the normal scan interface,
+i.e., the P2P module will call p2p_config::p2p_scan() just like in the
+full scan phase described. Similarly, scan results from the search
+operation will be delivered to the P2P module using the
+p2p_scan_res_handler() and p2p_scan_res_handled() functions.
+
+Once the upper layer management entity has found a peer with which it
+wants to connect by forming a new group, it initiates group owner
+negotiation by calling p2p_connect(). Before doing this, the upper
+layer code is responsible for asking the user to provide the PIN to be
+used during the provisioning step with the peer or the push button
+press for PBC mode. The glue code will need to figure out the intended
+interface address for the group before group owner negotiation can be
+started.
+
+Optional Provision Discovery mechanism can be used to request the peer
+to display a PIN for the local device to enter (and vice versa). Upper
+layer management entity can request the specific mechanism by calling
+p2p_prov_disc_req(). The response to this will be reported with the
+p2p_config::prov_disc_resp() callback. If the peer device started
+Provision Discovery, an accepted request will be reported with the
+p2p_config::prov_disc_req() callback. The P2P module will
+automatically accept the Provision Discovery for display and keypad
+methods, but it is up to the upper layer manegement entity to actually
+generate the PIN and to configure it with following p2p_connect() call
+to actually authorize the connection.
+
+The P2P module will use p2p_config::send_action() callback to request
+lower layer code to transmit an Action frame during group owner
+negotiation. p2p_send_action_cb() is used to report the result of
+transmission. If the peer is not reachable, the P2P module will try to
+find it by alternating between Action frame send and Listen
+states. The Listen state for this phase will be used similarly to the
+Listen state during device discovery as described above.
+
+Once the group owner negotiation has been completed, its results will
+be reported with the p2p_config::go_neg_completed() callback. The
+upper layer management code or the glue code using the P2P module API
+is responsible for creating a new group interface and starting
+provisioning step at this point by configuring WPS Registrar or
+Enrollee functionality based on the reported group owner negotiation
+results. The upper layer code is also responsible for timing out WPS
+provisioning if it cannot be completed in 15 seconds.
+
+Successful completion of the WPS provisioning is reported with a call
+to p2p_wps_success_cb(). The P2P module will clear its group formation
+state at this point and allows new group formation attempts to be
+started. The upper layer management code is responsible for configuring
+the GO to accept associations from devices and the client to connect to
+the GO with the provisioned credentials. GO is also responsible for
+calling p2p_group_notif_formation_done() as described below.
+
+If the WPS provisioning step fails or times out, this is reported with
+a call to p2p_group_formation_failed(). The P2P module will clear its
+group formation state at this point and allows new group formation
+attempts to be started. The upper layer management code is responsible
+for removing the group interface for the failed group.
+
+
+\section p2p_sd P2P service discovery
+
+P2P protocol includes service discovery functionality that can be used
+to discover which services are provided by the peers before forming a
+group. This leverages the Generic Advertisement Service (GAS) protocol
+from IEEE 802.11u and P2P vendor-specific contents inside the Native
+GAS messages.
+
+The P2P module takes care of GAS encapsulation, fragmentation, and
+actual transmission and reception of the Action frames needed for
+service discovery. The user of the P2P module is responsible for
+providing P2P specific Service Request TLV(s) for queries and Service
+Response TLV(s) for responses.
+
+\subsection p2p_sd_query Quering services of peers
+
+Service discovery is implemented by processing pending queries as a
+part of the device discovery phase. p2p_sd_request() function is used
+to schedule service discovery queries to a specific peer or to all
+discovered peers. p2p_sd_cancel_request() can be used to cancel a
+scheduled query. Queries that are specific to a single peer will be
+removed automatically after the response has been received.
+
+After the service discovery queries have been queued, device discovery
+is started with a call to p2p_find(). The pending service discovery
+queries are then sent whenever a peer is discovered during the find
+operation. Responses to the queries will be reported with the
+p2p_config::sd_response() callback.
+
+\subsection p2p_sd_response Replying to service discovery queries from peers
+
+The received service discovery requests will be indicated with the
+p2p_config::sd_request() callback. The response to the query is sent
+by calling p2p_sd_response().
+
+\subsection p2p_sd_indicator Service update indicator
+
+P2P service discovery provides a mechanism to notify peers about
+changes in available services. This works by incrementing Service
+Update Indicator value whenever there is a change in the
+services. This value is included in all SD request and response
+frames. The value received from the peers will be included in the
+p2p_config::sd_request() and p2p_config::sd_response() callbacks. The
+value to be sent to the peers is incremented with a call to
+p2p_sd_service_update() whenever availibility of the local services
+changes.
+
+
+\section p2p_go P2P group owner
+
+This section describes how P2P module can be used for managing
+per-group information in a group owner. The function calls are
+described based on the P2P module API. The exact design for the glue
+code outside the P2P module depends on the architecture used in the
+system.
+
+When a P2P group interface is created in group owner role, per-group
+data is initialized with p2p_group_init(). This call provides a
+pointer to the per-device P2P module context and configures the
+per-group operation. The configured p2p_group_config::ie_update()
+callback is used to set the initial P2P IE for Beacon and Probe
+Response frames in the group owner. The AP mode implementation may use
+this information to add IEs into the frames.
+
+Once the group formation has been completed (or if it is skipped in
+case of manual group setup), p2p_group_notif_formation_done() is
+called. This will allow the P2P module to update the P2P IE for
+Beacon and Probe Response frames.
+
+The SME/MLME code that managements IEEE 802.11 association processing
+needs to inform P2P module whenever a P2P client associates or
+disassociates with the group. This is done by calling
+p2p_group_notif_assoc() and p2p_group_notif_disassoc(). The P2P module
+manages a list of group members and updates the P2P Group Information
+subelement in the P2P IE based on the information from the P2P
+clients. The p2p_group_config::ie_update() callback is used whenever
+the P2P IE in Probe Response frames needs to be changed.
+
+The SME/MLME code that takes care of replying to Probe Request frames
+can use p2p_group_match_dev_type() to check whether the Probe Request
+frame request a reply only from groups that include a specific device
+type in one of the clients or GO. A match will be reported if the
+Probe Request does not request a specific device type, so this
+function can be used to filter or received Probe Request frames and
+only the ones that result in non-zero return value need to be replied.
+
+When the P2P group interface for GO role is removed,
+p2p_group_deinit() is used to deinitialize the per-group P2P module
+state.
+
+
+\section p2p_ctrl_iface P2P control interface
+
+%wpa_supplicant \ref ctrl_iface_page "control interface" can be used
+to manage P2P functionality from an external program (e.g., a GUI or a
+system configuration manager). This interface can be used directly
+through the control interface backend mechanism (e.g., local domain
+sockets on Linux) or with help of wpa_cli (e.g., from a script).

+\subsection p2p_wpa_gui GUI example (wpa_gui)
+
+wpa_gui has an example implementation of a GUI that could be used to
+manage P2P operations. The P2P related functionality is contained
+mostly in wpa_supplicant/wpa_gui-qt4/peers.cpp and it shows how the
+control interface commands and events can be used.
+
+
+\subsection p2p_wpa_cli wpa_cli example
+
+wpa_cli can be used to control %wpa_supplicant in interactive
+mode. The following sessions show examples of commands used for
+device discovery and group formation. The lines starting with "> " are
+commands from the user (followed by command result indication) and
+lines starting with "<2>" are event messages from %wpa_supplicant.

+/**
+\page porting Porting to different target boards and operating systems
+
+%wpa_supplicant was designed to be easily portable to different
+hardware (board, CPU) and software (OS, drivers) targets. It is
+already used with number of operating systems and numerous wireless
+card models and drivers. The main %wpa_supplicant repository includes
+support for Linux, FreeBSD, and Windows. In addition, the code has been
+ported to number of other operating systems like VxWorks, PalmOS,
+Windows CE, and Windows Mobile. On the hardware
+side, %wpa_supplicant is used on various systems: desktops, laptops,
+PDAs, and embedded devices with CPUs including x86, PowerPC,
+arm/xscale, and MIPS. Both big and little endian configurations are
+supported.
+
+
+\section ansi_c_extra Extra functions on top of ANSI C
+
+%wpa_supplicant is mostly using ANSI C functions that are available on
+most targets. However, couple of additional functions that are common
+on modern UNIX systems are used. Number of these are listed with
+prototypes in common.h (the \verbatim #ifdef CONFIG_ANSI_C_EXTRA \endverbatim
+block). These functions may need to be implemented or at least defined
+as macros to native functions in the target OS or C library.
+
+Many of the common ANSI C functions are used through a wrapper
+definitions in os.h to allow these to be replaced easily with a
+platform specific version in case standard C libraries are not
+available. In addition, os.h defines couple of common platform
+specific functions that are implemented in os_unix.c for UNIX like
+targets and in os_win32.c for Win32 API. If the target platform does
+not support either of these examples, a new os_*.c file may need to be
+added.
+
+Unless OS_NO_C_LIB_DEFINES is defined, the standard ANSI C and POSIX
+functions are used by defining the os_*() wrappers to use them
+directly in order to avoid extra cost in size and speed. If the target
+platform needs different versions of the functions, os.h can be
+modified to define the suitable macros or alternatively,
+OS_NO_C_LIB_DEFINES may be defined for the build and the wrapper
+functions can then be implemented in a new os_*.c wrapper file.
+
+common.h defines number of helper macros for handling integers of
+different size and byte order. Suitable version of these definitions
+may need to be added for the target platform.
+
+
+\section configuration_backend Configuration backend
+
+%wpa_supplicant implements a configuration interface that allows the
+backend to be easily replaced in order to read configuration data from
+a suitable source depending on the target platform. config.c
+implements the generic code that can be shared with all configuration
+backends. Each backend is implemented in its own config_*.c file.
+
+The included config_file.c backend uses a text file for configuration
+and config_winreg.c uses Windows registry. These files can be used as
+an example for a new configuration backend if the target platform uses
+different mechanism for configuration parameters. In addition,
+config_none.c can be used as an empty starting point for building a
+new configuration backend.
+
+
+\section driver_iface_porting Driver interface
+
+Unless the target OS and driver is already supported, most porting
+projects have to implement a driver wrapper. This may be done by
+adding a new driver interface module or modifying an existing module
+(driver_*.c) if the new target is similar to one of them. \ref
+driver_wrapper "Driver wrapper implementation" describes the details
+of the driver interface and discusses the tasks involved in porting
+this part of %wpa_supplicant.
+
+
+\section l2_packet_porting l2_packet (link layer access)
+
+%wpa_supplicant needs to have access to sending and receiving layer 2
+(link layer) packets with two Ethertypes: EAP-over-LAN (EAPOL) 0x888e
+and RSN pre-authentication 0x88c7. l2_packet.h defines the interfaces
+used for this in the core %wpa_supplicant implementation.
+
+If the target operating system supports a generic mechanism for link
+layer access, that is likely the best mechanism for providing the
+needed functionality for %wpa_supplicant. Linux packet socket is an
+example of such a generic mechanism. If this is not available, a
+separate interface may need to be implemented to the network stack or
+driver. This is usually an intermediate or protocol driver that is
+operating between the device driver and the OS network stack. If such
+a mechanism is not feasible, the interface can also be implemented
+directly in the device driver.
+
+The main %wpa_supplicant repository includes l2_packet implementations
+for Linux using packet sockets (l2_packet_linux.c), more portable
+version using libpcap/libdnet libraries (l2_packet_pcap.c; this
+supports WinPcap, too), and FreeBSD specific version of libpcap
+interface (l2_packet_freebsd.c).
+
+If the target operating system is supported by libpcap (receiving) and
+libdnet (sending), l2_packet_pcap.c can likely be used with minimal or
+no changes. If this is not a case or a proprietary interface for link
+layer is required, a new l2_packet module may need to be
+added. Alternatively, struct wpa_driver_ops::send_eapol() handler can
+be used to override the l2_packet library if the link layer access is
+integrated with the driver interface implementation.
+
+
+\section eloop_porting Event loop
+
+%wpa_supplicant uses a single process/thread model and an event loop
+to provide callbacks on events (registered timeout, received packet,
+signal). eloop.h defines the event loop interface. eloop.c is an
+implementation of such an event loop using select() and sockets. This
+is suitable for most UNIX/POSIX systems. When porting to other
+operating systems, it may be necessary to replace that implementation
+with OS specific mechanisms that provide similar functionality.
+
+
+\section ctrl_iface_porting Control interface
+
+%wpa_supplicant uses a \ref ctrl_iface_page "control interface"
+to allow external processed
+to get status information and to control the operations. Currently,
+this is implemented with socket based communication; both UNIX domain
+sockets and UDP sockets are supported. If the target OS does not
+support sockets, this interface will likely need to be modified to use
+another mechanism like message queues. The control interface is
+optional component, so it is also possible to run %wpa_supplicant
+without porting this part.
+
+The %wpa_supplicant side of the control interface is implemented in
+ctrl_iface.c. Matching client side is implemented as a control
+interface library in wpa_ctrl.c.
+
+
+\section entry_point Program entry point
+
+%wpa_supplicant defines a set of functions that can be used to
+initialize main supplicant processing. Each operating system has a
+mechanism for starting new processing or threads. This is usually a
+function with a specific set of arguments and calling convention. This
+function is responsible on initializing %wpa_supplicant.
+
+main.c includes an entry point for UNIX-like operating system, i.e.,
+main() function that uses command line arguments for setting
+parameters for %wpa_supplicant. When porting to other operating
+systems, similar OS-specific entry point implementation is needed. It
+can be implemented in a new file that is then linked with
+%wpa_supplicant instead of main.o. main.c is also a good example on
+how the initialization process should be done.
+
+The supplicant initialization functions are defined in
+wpa_supplicant_i.h. In most cases, the entry point function should
+start by fetching configuration parameters. After this, a global
+%wpa_supplicant context is initialized with a call to
+wpa_supplicant_init(). After this, existing network interfaces can be
+added with wpa_supplicant_add_iface(). wpa_supplicant_run() is then
+used to start the main event loop. Once this returns at program
+termination time, wpa_supplicant_deinit() is used to release global
+context data.
+
+wpa_supplicant_add_iface() and wpa_supplicant_remove_iface() can be
+used dynamically to add and remove interfaces based on when
+%wpa_supplicant processing is needed for them. This can be done, e.g.,
+when hotplug network adapters are being inserted and ejected. It is
+also possible to do this when a network interface is being
+enabled/disabled if it is desirable that %wpa_supplicant processing
+for the interface is fully enabled/disabled at the same time.
+
+
+\section simple_build Simple build example
+
+One way to start a porting project is to begin with a very simple
+build of %wpa_supplicant with WPA-PSK support and once that is
+building correctly, start adding features.
+
+Following command can be used to build very simple version of
+%wpa_supplicant:
+
+\verbatim
+cc -o wpa_supplicant config.c eloop.c common.c md5.c rc4.c sha1.c \
+	config_none.c l2_packet_none.c tls_none.c wpa.c preauth.c \
+	aes_wrap.c wpa_supplicant.c events.c main_none.c drivers.c
+\endverbatim
+
+The end result is not really very useful since it uses empty functions
+for configuration parsing and layer 2 packet access and does not
+include a driver interface. However, this is a good starting point
+since the build is complete in the sense that all functions are
+present and this is easy to configure to a build system by just
+including the listed C files.
+
+Once this version can be build successfully, the end result can be
+made functional by adding a proper program entry point (main*.c),
+driver interface (driver_*.c and matching CONFIG_DRIVER_* define for
+registration in drivers.c), configuration parser/writer (config_*.c),
+and layer 2 packet access implementation (l2_packet_*.c). After these
+components have been added, the end result should be a working
+WPA/WPA2-PSK enabled supplicant.
+
+After the basic functionality has been verified to work, more features
+can be added by linking in more files and defining C pre-processor
+defines. Currently, the best source of information for what options
+are available and which files needs to be included is in the Makefile
+used for building the supplicant with make. Similar configuration will
+be needed for build systems that either use different type of make
+tool or a GUI-based project configuration.

+
+%wpa_supplicant source tree includes number of testing and development
+tools that make it easier to test the programs without having to setup
+a full test setup with wireless cards. In addition, these tools can be
+used to implement automatic tests suites.
+
+\section eapol_test eapol_test - EAP peer and RADIUS client testing
+
+eapol_test is a program that links together the same EAP peer
+implementation that %wpa_supplicant is using and the RADIUS
+authentication client code from hostapd. In addition, it has minimal
+glue code to combine these two components in similar ways to IEEE
+802.1X/EAPOL Authenticator state machines. In other words, it
+integrates IEEE 802.1X Authenticator (normally, an access point) and
+IEEE 802.1X Supplicant (normally, a wireless client) together to
+generate a single program that can be used to test EAP methods without
+having to setup an access point and a wireless client.
+
+The main uses for eapol_test are in interoperability testing of EAP
+methods against RADIUS servers and in development testing for new EAP
+methods. It can be easily used to automate EAP testing for
+interoperability and regression since the program can be run from
+shell scripts without require additional test components apart from a
+RADIUS server. For example, the automated EAP tests described in
+eap_testing.txt are implemented with eapol_test. Similarly, eapol_test
+could be used to implement an automated regression test suite for a
+RADIUS authentication server.
+
+eapol_test uses the same build time configuration file, .config, as
+%wpa_supplicant. This file is used to select which EAP methods are
+included in eapol_test. This program is not built with the default
+Makefile target, so a separate make command needs to be used to
+compile the tool:
+
+\verbatim
+make eapol_test
+\endverbatim
+
+The resulting eapol_test binary has following command like options:
+
+\verbatim
+usage:
+eapol_test [-nWS] -c<conf> [-a<AS IP>] [-p<AS port>] [-s<AS secret>] \
+           [-r<count>] [-t<timeout>] [-C<Connect-Info>] \
+           [-M<client MAC address>]
+eapol_test scard
+eapol_test sim <PIN> <num triplets> [debug]
+
+options:
+  -c<conf> = configuration file
+  -a<AS IP> = IP address of the authentication server, default 127.0.0.1
+  -p<AS port> = UDP port of the authentication server, default 1812
+  -s<AS secret> = shared secret with the authentication server, default 'radius'
+  -r<count> = number of re-authentications
+  -W = wait for a control interface monitor before starting
+  -S = save configuration after authentiation
+  -n = no MPPE keys expected
+  -t<timeout> = sets timeout in seconds (default: 30 s)
+  -C<Connect-Info> = RADIUS Connect-Info (default: CONNECT 11Mbps 802.11b)
+  -M<client MAC address> = Set own MAC address (Calling-Station-Id,
+                           default: 02:00:00:00:00:01)
+\endverbatim
+
+
+As an example,
+\verbatim
+eapol_test -ctest.conf -a127.0.0.1 -p1812 -ssecret -r1
+\endverbatim
+tries to complete EAP authentication based on the network
+configuration from test.conf against the RADIUS server running on the
+local host. A re-authentication is triggered to test fast
+re-authentication. The configuration file uses the same format for
+network blocks as %wpa_supplicant.
+
+
+\section preauth_test preauth_test - WPA2 pre-authentication and EAP peer testing
+
+preauth_test is similar to eapol_test in the sense that in combines
+EAP peer implementation with something else, in this case, with WPA2
+pre-authentication. This tool can be used to test pre-authentication
+based on the code that %wpa_supplicant is using. As such, it tests
+both the %wpa_supplicant implementation and the functionality of an
+access point.
+
+preauth_test is built with:
+
+\verbatim
+make preauth_test
+\endverbatim
+
+and it uses following command line arguments:
+
+\verbatim
+usage: preauth_test <conf> <target MAC address> <ifname>
+\endverbatim
+
+For example,
+\verbatim
+preauth_test test.conf 02:11:22:33:44:55 eth0
+\endverbatim
+would use network configuration from test.conf to try to complete
+pre-authentication with AP using BSSID 02:11:22:33:44:55. The
+pre-authentication packets would be sent using the eth0 interface.
+
+
+\section driver_test driver_test - driver interface for testing wpa_supplicant
+
+%wpa_supplicant was designed to support number of different ways to
+communicate with a network device driver. This design uses \ref
+driver_wrapper "driver interface API" and number of driver interface
+implementations. One of these is driver_test.c, i.e., a test driver
+interface that is actually not using any drivers. Instead, it provides
+a mechanism for running %wpa_supplicant without having to have a
+device driver or wireless LAN hardware for that matter.
+
+driver_test can be used to talk directly with hostapd's driver_test
+component to create a test setup where one or more clients and access
+points can be tested within one test host and without having to have
+multiple wireless cards. This makes it easier to test the core code in
+%wpa_supplicant, and hostapd for that matter. Since driver_test uses
+the same driver API than any other driver interface implementation,
+the core code of %wpa_supplicant and hostapd can be tested with the
+same coverage as one would get when using real wireless cards. The
+only area that is not tested is the driver interface implementation
+(driver_*.c).
+
+Having the possibility to use simulated network components makes it
+much easier to do development testing while adding new features and to
+reproduce reported bugs. As such, it is often easiest to just do most
+of the development and bug fixing without using real hardware. Once
+the driver_test setup has been used to implement a new feature or fix
+a bug, the end result can be verified with wireless LAN cards. In many
+cases, this may even be unnecessary, depending on what area the
+feature/bug is relating to. Of course, changes to driver interfaces
+will still require use of real hardware.
+
+Since multiple components can be run within a single host, testing of
+complex network configuration, e.g., large number of clients
+association with an access point, becomes quite easy. All the tests
+can also be automated without having to resort to complex test setup
+using remote access to multiple computers.
+
+driver_test can be included in the %wpa_supplicant build in the same
+way as any other driver interface, i.e., by adding the following line
+into .config:
+
+\verbatim
+CONFIG_DRIVER_TEST=y
+\endverbatim
+
+When running %wpa_supplicant, the test interface is selected by using
+\a -Dtest command line argument. The interface name (\a -i argument)
+can be selected arbitrarily, i.e., it does not need to match with any
+existing network interface. The interface name is used to generate a
+MAC address, so when using multiple clients, each should use a
+different interface, e.g., \a sta1, \a sta2, and so on.
+
+%wpa_supplicant and hostapd are configured in the same way as they
+would be for normal use. Following example shows a simple test setup
+for WPA-PSK.
+
+hostapd is configured with following psk-test.conf configuration file:
+
+\verbatim
+driver=test
+
+interface=ap1
+logger_stdout=-1
+logger_stdout_level=0
+debug=2
+dump_file=/tmp/hostapd.dump
+
+test_socket=/tmp/Test/ap1
+
+ssid=jkm-test-psk
+
+wpa=1
+wpa_key_mgmt=WPA-PSK
+wpa_pairwise=TKIP
+wpa_passphrase=12345678
+\endverbatim
+
+and started with following command:
+
+\verbatim
+hostapd psk-test.conf
+\endverbatim
+
+%wpa_supplicant uses following configuration file:
+
+\verbatim
+driver_param=test_socket=/tmp/Test/ap1
+
+network={
+    ssid="jkm-test-psk"
+    key_mgmt=WPA-PSK
+    psk="12345678"
+}
+\endverbatim
+
+%wpa_supplicant can then be started with following command:
+
+\verbatim
+wpa_supplicant -Dtest -cpsk-test.conf -ista1 -ddK
+\endverbatim
+
+If run without debug information, i.e., with
+
+\verbatim
+wpa_supplicant -Dtest -cpsk-test.conf -ista1
+\endverbatim
+
+%wpa_supplicant completes authentication and prints following events:
+
+\verbatim
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a
+WPA: Key negotiation completed with 02:b8:a6:62:08:5a [PTK=TKIP GTK=TKIP]
+CTRL-EVENT-CONNECTED - Connection to 02:b8:a6:62:08:5a completed (auth)
+\endverbatim
+
+If test setup is using multiple clients, it is possible to run
+multiple %wpa_supplicant processes. Alternatively, the support for
+multiple interfaces can be used with just one process to save some
+resources on single-CPU systems. For example, following command runs
+two clients:
+
+\verbatim
+./wpa_supplicant -Dtest -cpsk-test.conf -ista1 \
+	-N -Dtest -cpsk-test.conf -ista2
+\endverbatim
+
+This shows following event log:
+
+\verbatim
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a
+WPA: Key negotiation completed with 02:b8:a6:62:08:5a [PTK=TKIP GTK=TKIP]
+CTRL-EVENT-CONNECTED - Connection to 02:b8:a6:62:08:5a completed (auth)
+Trying to associate with 02:b8:a6:62:08:5a (SSID='jkm-test-psk' freq=0 MHz)
+Associated with 02:b8:a6:62:08:5a
+WPA: Key negotiation completed with 02:b8:a6:62:08:5a [PTK=TKIP GTK=TKIP]
+CTRL-EVENT-CONNECTED - Connection to 02:b8:a6:62:08:5a completed (auth)
+\endverbatim
+
+hostapd shows this with following events:
+
+\verbatim
+ap1: STA 02:b5:64:63:30:63 IEEE 802.11: associated
+ap1: STA 02:b5:64:63:30:63 WPA: pairwise key handshake completed (WPA)
+ap1: STA 02:b5:64:63:30:63 WPA: group key handshake completed (WPA)
+ap1: STA 02:2a:c4:18:5b:f3 IEEE 802.11: associated
+ap1: STA 02:2a:c4:18:5b:f3 WPA: pairwise key handshake completed (WPA)
+ap1: STA 02:2a:c4:18:5b:f3 WPA: group key handshake completed (WPA)
+\endverbatim
+
+By default, driver_param is simulating a driver that uses the WPA/RSN
+IE generated by %wpa_supplicant. Driver-generated IE and AssocInfo
+events can be tested by adding \a use_associnfo=1 to the \a driver_param
+line in the configuration file. For example:
+
+\verbatim
+driver_param=test_socket=/tmp/Test/ap1 use_associnfo=1
+\endverbatim
+
+
+\section unit_tests Unit tests
+
+Number of the components (.c files) used in %wpa_supplicant define
+their own unit tests for automated validation of the basic
+functionality. Most of the tests for cryptographic algorithms are
+using standard test vectors to validate functionality. These tests can
+be useful especially when verifying port to a new CPU target.
+
+The test programs are collected in the tests subdirectory. All
+automated unit tests can be run with
+
+\verbatim
+make run-tests
+\endverbatim
+
+This make target builds and runs each test and terminates with zero
+exit code if all tests were completed successfully.
+
+
+\section wpa_trace Tracing code for developer debuggin
+
+%wpa_supplicant and hostapd can be built with tracing code that will
+track and analyze memory allocations and other resource registrations
+and certain API uses. If incorrect use is detected, a backtrace of the
+call location (and/or allocation location) is shown. This can also be
+used to detect certain categories of memory leaks and report them
+automatically when the program is terminated. The report will also
+include information about forgotten eloop events.
+
+The trace code can be enabled with CONFIG_WPA_TRACE=y build
+option. More verbose backtrace information can be generated if libbfd
+is available and the binaries are not stripped of symbol
+information. This is enabled with CONFIG_WPA_TRACE_BFD=y.
+
+For example, a memory leak (forgotten os_free() call) would show up
+like this when the program is terminated:
+
+\verbatim
+MEMLEAK[0x82d200]: len 128
+WPA_TRACE: memleak - START
+[0]: ./wpa_supplicant(os_malloc+0x59) [0x41a5e9]
+     os_malloc() ../src/utils/os_unix.c:359
+[1]: ./wpa_supplicant(os_zalloc+0x16) [0x41a676]
+     os_zalloc() ../src/utils/os_unix.c:418
+[2]: ./wpa_supplicant(wpa_supplicant_init+0x38) [0x48b508]
+     wpa_supplicant_init() wpa_supplicant.c:2315
+[3]: ./wpa_supplicant(main+0x2f3) [0x491073]
+     main() main.c:252
+WPA_TRACE: memleak - END
+MEMLEAK: total 128 bytes
+\endverbatim
+
+Another type of error that can be detected is freeing of memory area
+that was registered for some use and is still be referenced:
+
+\verbatim
+WPA_TRACE: Freeing referenced memory - START
+[2]: ./wpa_supplicant(os_free+0x5c) [0x41a53c]
+     os_free() ../src/utils/os_unix.c:411
+[3]: ./wpa_supplicant(wpa_supplicant_remove_iface+0x30) [0x48b380]
+     wpa_supplicant_remove_iface() wpa_supplicant.c:2259
+[4]: ./wpa_supplicant(wpa_supplicant_deinit+0x20) [0x48b3e0]
+     wpa_supplicant_deinit() wpa_supplicant.c:2430
+[5]: ./wpa_supplicant(main+0x357) [0x4910d7]
+     main() main.c:276
+WPA_TRACE: Freeing referenced memory - END
+WPA_TRACE: Reference registration - START
+[1]: ./wpa_supplicant [0x41c040]
+     eloop_trace_sock_add_ref() ../src/utils/eloop.c:94
+[2]: ./wpa_supplicant(wpa_supplicant_ctrl_iface_deinit+0x17) [0x473247]
+     wpa_supplicant_ctrl_iface_deinit() ctrl_iface_unix.c:436
+[3]: ./wpa_supplicant [0x48b21c]
+     wpa_supplicant_cleanup() wpa_supplicant.c:378
+     wpa_supplicant_deinit_iface() wpa_supplicant.c:2155
+[4]: ./wpa_supplicant(wpa_supplicant_remove_iface+0x30) [0x48b380]
+     wpa_supplicant_remove_iface() wpa_supplicant.c:2259
+[5]: ./wpa_supplicant(wpa_supplicant_deinit+0x20) [0x48b3e0]
+     wpa_supplicant_deinit() wpa_supplicant.c:2430
+[6]: ./wpa_supplicant(main+0x357) [0x4910d7]
+     main() main.c:276
+WPA_TRACE: Reference registration - END
+Aborted
+\endverbatim
+
+This type of error results in showing backtraces for both the location
+where the incorrect freeing happened and the location where the memory
+area was marked referenced.

+EAP peer/server library and example program
+Copyright (c) 2007, Jouni Malinen <j@w1.fi>
+
+This software may be distributed under the terms of the BSD license.
+See the parent directory README for more details.
+
+
+The interfaces of the EAP server/peer implementation are based on RFC
+4137 (EAP State Machines). This RFC is coordinated with the state
+machines defined in IEEE 802.1X-2004. hostapd and wpa_supplicant
+include implementation of the IEEE 802.1X EAPOL state machines and the
+interface between them and EAP. However, the EAP implementation can be
+used with other protocols, too, by providing a compatible interface
+which maps the EAPOL<->EAP variables to another protocol.
+
+This directory contains an example showing how EAP peer and server
+code from wpa_supplicant and hostapd can be used as a library. The
+example program initializes both an EAP server and an EAP peer
+entities and then runs through an EAP-PEAP/MSCHAPv2 authentication.
+
+eap_example_peer.c shows the initialization and glue code needed to
+control the EAP peer implementation. eap_example_server.c does the
+same for EAP server. eap_example.c is an example that ties in both the
+EAP server and client parts to allow an EAP authentication to be
+shown.
+
+In this example, the EAP messages are passed between the server and
+the peer are passed by direct function calls within the same process.
+In practice, server and peer functionalities would likely reside in
+separate devices and the EAP messages would be transmitted between the
+devices based on an external protocol. For example, in IEEE 802.11
+uses IEEE 802.1X EAPOL state machines to control the transmission of
+EAP messages and WiMax supports optional PMK EAP authentication
+mechanism that transmits EAP messages as defined in IEEE 802.16e.
+
+
+The EAP library links in number of helper functions from src/utils and
+src/crypto directories. Most of these are suitable as-is, but it may
+be desirable to replace the debug output code in src/utils/wpa_debug.c
+by dropping this file from the library and re-implementing the
+functions there in a way that better fits in with the main
+application.

+ChangeLog for hostapd
+
+2013-01-12 - v2.0
+	* added AP-STA-DISCONNECTED ctrl_iface event
+	* improved debug logging (human readable event names, interface name
+	  included in more entries)
+	* added number of small changes to make it easier for static analyzers
+	  to understand the implementation
+	* added a workaround for Windows 7 Michael MIC failure reporting and
+	  use of the Secure bit in EAPOL-Key msg 3/4
+	* fixed number of small bugs (see git logs for more details)
+	* changed OpenSSL to read full certificate chain from server_cert file
+	* nl80211: number of updates to use new cfg80211/nl80211 functionality
+	  - replace monitor interface with nl80211 commands
+	  - additional information for driver-based AP SME
+	* EAP-pwd:
+	  - fix KDF for group 21 and zero-padding
+	  - added support for fragmentation
+	  - increased maximum number of hunting-and-pecking iterations
+	* avoid excessive Probe Response retries for broadcast Probe Request
+	  frames (only with drivers using hostapd SME/MLME)
+	* added preliminary support for using TLS v1.2 (CONFIG_TLSV12=y)
+	* fixed WPS operation stopping on dual concurrent AP
+	* added wps_rf_bands configuration parameter for overriding RF Bands
+	  value for WPS
+	* added support for getting per-device PSK from RADIUS Tunnel-Password
+	* added support for libnl 3.2 and newer
+	* increased initial group key handshake retransmit timeout to 500 ms
+	* added a workaround for 4-way handshake to update SNonce even after
+	  having sent EAPOL-Key 3/4 to avoid issues with some supplicant
+	  implementations that can change SNonce for each EAP-Key 2/4
+	* added a workaround for EAPOL-Key 4/4 using incorrect type value in
+	  WPA2 mode (some deployed stations use WPA type in that message)
+	* added a WPS workaround for mixed mode AP Settings with Windows 7
+	* changed WPS AP PIN disabling mechanism to disable the PIN after 10
+	  consecutive failures in addition to using the exponential lockout
+	  period
+	* added support for WFA Hotspot 2.0
+	  - GAS/ANQP advertisement of network information
+	  - disable_dgaf parameter to disable downstream group-addressed
+	    forwarding
+	* simplified licensing terms by selecting the BSD license as the only
+	  alternative
+	* EAP-SIM: fixed re-authentication not to update pseudonym
+	* EAP-SIM: use Notification round before EAP-Failure
+	* EAP-AKA: added support for AT_COUNTER_TOO_SMALL
+	* EAP-AKA: skip AKA/Identity exchange if EAP identity is recognized
+	* EAP-AKA': fixed identity for MK derivation
+	* EAP-AKA': updated to RFC 5448 (username prefixes changed); note: this
+	  breaks interoperability with older versions
+	* EAP-SIM/AKA: allow pseudonym to be used after unknown reauth id
+	* changed ANonce to be a random number instead of Counter-based
+	* added support for canceling WPS operations with hostapd_cli wps_cancel
+	* fixed EAP/WPS to PSK transition on reassociation in cases where
+	  deauthentication is missed
+	* hlr_auc_gw enhancements:
+	  - a new command line parameter -u can be used to enable updating of
+	    SQN in Milenage file
+	  - use 5 bit IND for SQN updates
+	  - SQLite database can now be used to store Milenage information
+	* EAP-SIM/AKA DB: added optional use of SQLite database for pseudonyms
+	  and reauth data
+	* added support for Chargeable-User-Identity (RFC 4372)
+	* added radius_auth_req_attr and radius_acct_req_attr configuration
+	  parameters to allow adding/overriding of RADIUS attributes in
+	  Access-Request and Accounting-Request packets
+	* added support for RADIUS dynamic authorization server (RFC 5176)
+	* added initial support for WNM operations
+	  - BSS max idle period
+	  - WNM-Sleep Mode
+	* added new WPS NFC ctrl_iface mechanism
+	  - removed obsoleted WPS_OOB command (including support for deprecated
+	    UFD config_method)
+	* added FT support for drivers that implement MLME internally
+	* added SA Query support for drivers that implement MLME internally
+	* removed default ACM=1 from AC_VO and AC_VI
+	* changed VENDOR-TEST EAP method to use proper private enterprise number
+	  (this will not interoperate with older versions)
+	* added hostapd.conf parameter vendor_elements to allow arbitrary vendor
+	  specific elements to be added to the Beacon and Probe Response frames
+	* added support for configuring GCMP cipher for IEEE 802.11ad
+	* added support for 256-bit AES with internal TLS implementation
+	* changed EAPOL transmission to use AC_VO if WMM is active
+	* fixed EAP-TLS/PEAP/TTLS/FAST server to validate TLS Message Length
+	  correctly; invalid messages could have caused the hostapd process to
+	  terminate before this fix [CVE-2012-4445]
+	* limit number of active wildcard PINs for WPS Registrar to one to avoid
+	  confusing behavior with multiple wildcard PINs
+	* added a workaround for WPS PBC session overlap detection to avoid
+	  interop issues with deployed station implementations that do not
+	  remove active PBC indication from Probe Request frames properly
+	* added support for using SQLite for the eap_user database
+	* added Acct-Session-Id attribute into Access-Request messages
+	* fixed EAPOL frame transmission to non-QoS STAs with nl80211
+	  (do not send QoS frames if the STA did not negotiate use of QoS for
+	  this association)
+
+2012-05-10 - v1.0
+	* Add channel selection support in hostapd. See hostapd.conf.
+	* Add support for IEEE 802.11v Time Advertisement mechanism with UTC
+	  TSF offset. See hostapd.conf for config info.
+	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
+	  This allows the driver to use PS buffering of Deauthentication and
+	  Disassociation frames when the STA is in power save sleep. Only
+	  available with drivers that provide TX status events for Deauth/
+	  Disassoc frames (nl80211).
+	* Allow PMKSA caching to be disabled on the Authenticator. See
+	  hostap.conf config parameter disable_pmksa_caching.
+	* atheros: Add support for IEEE 802.11w configuration.
+	* bsd: Add support for setting HT values in IFM_MMASK.
+	* Allow client isolation to be configured with ap_isolate. Client
+	  isolation can be used to prevent low-level bridging of frames
+	  between associated stations in the BSS. By default, this bridging
+	  is allowed.
+	* Allow coexistance of HT BSSes with WEP/TKIP BSSes.
+	* Add require_ht config parameter, which can be used to configure
+	  hostapd to reject association with any station that does not support
+	  HT PHY.
+	* Add support for writing debug log to a file using "-f" option. Also
+	  add relog CLI command to re-open the log file.
+	* Add bridge handling for WDS STA interfaces. By default they are
+	  added to the configured bridge of the AP interface (if present),
+	  but the user can also specify a separate bridge using cli command
+	  wds_bridge.
+	* hostapd_cli:
+	  - Add wds_bridge command for specifying bridge for WDS STA
+	    interfaces.
+	  - Add relog command for reopening log file.
+	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
+	    due to inactivity.
+	  - Add wps_config ctrl_interface command for configuring AP. This
+	    command can be used to configure the AP using the internal WPS
+	    registrar. It works in the same way as new AP settings received
+	    from an ER.
+	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
+	  - Add command get version, that returns hostapd version string.
+	* WNM: Add BSS Transition Management Request for ESS Disassoc Imminent.
+	  Use hostapd_cli ess_disassoc (STA addr) (URL) to send the
+	  notification to the STA.
+	* Allow AP mode to disconnect STAs based on low ACK condition (when
+	  the data connection is not working properly, e.g., due to the STA
+	  going outside the range of the AP). Disabled by default, enable by
+	  config option disassoc_low_ack.
+	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
+	  config file.
+	* WPS:
+	  - Send AP Settings as a wrapped Credential attribute to ctrl_iface
+	    in WPS-NEW-AP-SETTINGS.
+	  - Dispatch more WPS events through hostapd ctrl_iface.
+	  - Add mechanism for indicating non-standard WPS errors.
+	  - Change concurrent radio AP to use only one WPS UPnP instance.
+	  - Add wps_check_pin command for processing PIN from user input.
+	    UIs can use this command to process a PIN entered by a user and to
+	    validate the checksum digit (if present).
+	  - Add hostap_cli get_config command to display current AP config.
+	  - Add new hostapd_cli command, wps_ap_pin, to manage AP PIN at
+	    runtime and support dynamic AP PIN management.
+	  - Disable AP PIN after 10 consecutive failures. Slow down attacks
+	    on failures up to 10.
+	  - Allow AP to start in Enrollee mode without AP PIN for probing,
+	    to be compatible with Windows 7.
+	  - Add Config Error into WPS-FAIL events to provide more info
+	    to the user on how to resolve the issue.
+	  - When controlling multiple interfaces:
+	     - apply WPS commands to all interfaces configured to use WPS
+	     - apply WPS config changes to all interfaces that use WPS
+	     - when an attack is detected on any interface, disable AP PIN on
+	       all interfaces
+	* WPS ER:
+	  - Show SetSelectedRegistrar events as ctrl_iface events.
+	  - Add special AP Setup Locked mode to allow read only ER.
+	    ap_setup_locked=2 can now be used to enable a special mode where
+	    WPS ER can learn the current AP settings, but cannot change them.
+	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
+	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
+	    for testing protocol extensibility.
+	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
+	    workarounds.
+	  - Add support for AuthorizedMACs attribute.
+	* TDLS:
+	  - Allow TDLS use or TDLS channel switching in the BSS to be
+	    prohibited in the BSS, using config params tdls_prohibit and
+	    tdls_prohibit_chan_switch.
+	* EAP server: Add support for configuring fragment size (see
+	  fragment_size in hostapd.conf).
+	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
+	  wlantest can be used to capture frames from a monitor interface
+	  for realtime capturing or from pcap files for offline analysis.
+	* Interworking: Support added for 802.11u. Enable in .config with
+	  CONFIG_INTERWORKING. See hostapd.conf for config parameters for
+	  interworking.
+	* Android: Add build and runtime support for Android hostapd.
+	* Add a new debug message level for excessive information. Use
+	  -ddd to enable.
+	* TLS: Add support for tls_disable_time_checks=1 in client mode.
+	* Internal TLS:
+	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
+	    CONFIG_TLSV11.
+	  - Add domainComponent parser for X.509 names
+	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
+	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
+	  Move HT IEs to be later in (Re)Assoc Resp.
+	* Many bugfixes.
+
+2010-04-18 - v0.7.2
+	* fix WPS internal Registrar use when an external Registrar is also
+	  active
+	* bsd: Cleaned up driver wrapper and added various low-level
+	  configuration options
+	* TNC: fixed issues with fragmentation
+	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
+	  interoperate with other implementations; may potentially breaks
+	  compatibility with older wpa_supplicant/hostapd versions)
+	* cleaned up driver wrapper API for multi-BSS operations
+	* nl80211: fix multi-BSS and VLAN operations
+	* fix number of issues with IEEE 802.11r/FT; this version is not
+	  backwards compatible with old versions
+	* add SA Query Request processing in AP mode (IEEE 802.11w)
+	* fix IGTK PN in group rekeying (IEEE 802.11w)
+	* fix WPS PBC session overlap detection to use correct attribute
+	* hostapd_notif_Assoc() can now be called with all IEs to simplify
+	  driver wrappers
+	* work around interoperability issue with some WPS External Registrar
+	  implementations
+	* nl80211: fix WPS IE update
+	* hostapd_cli: add support for action script operations (run a script
+	  on hostapd events)
+	* fix DH padding with internal crypto code (mainly, for WPS)
+	* fix WPS association with both WPS IE and WPA/RSN IE present with
+	  driver wrappers that use hostapd MLME (e.g., nl80211)
+
+2010-01-16 - v0.7.1
+	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
+	  is not fully backwards compatible, so out-of-tree driver wrappers
+	  will need modifications
+	* cleaned up various module interfaces
+	* merge hostapd and wpa_supplicant developers' documentation into a
+	  single document
+	* fixed HT Capabilities IE with nl80211 drivers
+	* moved generic AP functionality code into src/ap
+	* WPS: handle Selected Registrar as union of info from all Registrars
+	* remove obsolte Prism54.org driver wrapper
+	* added internal debugging mechanism with backtrace support and memory
+	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
+	* EAP-FAST server: piggyback Phase 2 start with the end of Phase 1
+	* WPS: add support for dynamically selecting whether to provision the
+	  PSK as an ASCII passphrase or PSK
+	* added support for WDS (4-address frame) mode with per-station virtual
+	  interfaces (wds_sta=1 in config file; only supported with
+	  driver=nl80211 for now)
+	* fixed WPS Probe Request processing to handle missing required
+	  attribute
+	* fixed PKCS#12 use with OpenSSL 1.0.0
+	* detect bridge interface automatically so that bridge parameter in
+	  hostapd.conf becomes optional (though, it may now be used to
+	  automatically add then WLAN interface into a bridge with
+	  driver=nl80211)
+
+2009-11-21 - v0.7.0
+	* increased hostapd_cli ping interval to 5 seconds and made this
+	  configurable with a new command line options (-G<seconds>)
+	* driver_nl80211: use Linux socket filter to improve performance
+	* added support for external Registrars with WPS (UPnP transport)
+	* 802.11n: scan for overlapping BSSes before starting 20/40 MHz channel
+	* driver_nl80211: fixed STA accounting data collection (TX/RX bytes
+	  reported correctly; TX/RX packets not yet available from kernel)
+	* added support for WPS USBA out-of-band mechanism with USB Flash
+	  Drives (UFD) (CONFIG_WPS_UFD=y)
+	* fixed EAPOL/EAP reauthentication when using an external RADIUS
+	  authentication server
+	* fixed TNC with EAP-TTLS
+	* fixed IEEE 802.11r key derivation function to match with the standard
+	  (note: this breaks interoperability with previous version) [Bug 303]
+	* fixed SHA-256 based key derivation function to match with the
+	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
+	  (note: this breaks interoperability with previous version) [Bug 307]
+	* added number of code size optimizations to remove unnecessary
+	  functionality from the program binary based on build configuration
+	  (part of this automatic; part configurable with CONFIG_NO_* build
+	  options)
+	* use shared driver wrapper files with wpa_supplicant
+	* driver_nl80211: multiple updates to provide support for new Linux
+	  nl80211/mac80211 functionality
+	* updated management frame protection to use IEEE Std 802.11w-2009
+	* fixed number of small WPS issues and added workarounds to
+	  interoperate with common deployed broken implementations
+	* added some IEEE 802.11n co-existence rules to disable 40 MHz channels
+	  or modify primary/secondary channels if needed based on neighboring
+	  networks
+	* added support for NFC out-of-band mechanism with WPS
+	* added preliminary support for IEEE 802.11r RIC processing
+
+2009-01-06 - v0.6.7
+	* added support for Wi-Fi Protected Setup (WPS)
+	  (hostapd can now be configured to act as an integrated WPS Registrar
+	  and provision credentials for WPS Enrollees using PIN and PBC
+	  methods; external wireless Registrar can configure the AP, but
+	  external WLAN Manager Registrars are not supported); WPS support can
+	  be enabled by adding CONFIG_WPS=y into .config and setting the
+	  runtime configuration variables in hostapd.conf (see WPS section in
+	  the example configuration file); new hostapd_cli commands wps_pin and
+	  wps_pbc are used to configure WPS negotiation; see README-WPS for
+	  more details
+	* added IEEE 802.11n HT capability configuration (ht_capab)
+	* added support for generating Country IE based on nl80211 regulatory
+	  information (added if ieee80211d=1 in configuration)
+	* fixed WEP authentication (both Open System and Shared Key) with
+	  mac80211
+	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
+	* added support for using driver_test over UDP socket
+	* changed EAP-GPSK to use the IANA assigned EAP method type 51
+	* updated management frame protection to use IEEE 802.11w/D7.0
+	* fixed retransmission of EAP requests if no response is received
+
+2008-11-23 - v0.6.6
+	* added a new configuration option, wpa_ptk_rekey, that can be used to
+	  enforce frequent PTK rekeying, e.g., to mitigate some attacks against
+	  TKIP deficiencies
+	* updated OpenSSL code for EAP-FAST to use an updated version of the
+	  session ticket overriding API that was included into the upstream
+	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
+	  needed with that version anymore)
+	* changed channel flags configuration to read the information from
+	  the driver (e.g., via driver_nl80211 when using mac80211) instead of
+	  using hostapd as the source of the regulatory information (i.e.,
+	  information from CRDA is now used with mac80211); this allows 5 GHz
+	  channels to be used with hostapd (if allowed in the current
+	  regulatory domain)
+	* fixed EAP-TLS message processing for the last TLS message if it is
+	  large enough to require fragmentation (e.g., if a large Session
+	  Ticket data is included)
+	* fixed listen interval configuration for nl80211 drivers
+
+2008-11-01 - v0.6.5
+	* added support for SHA-256 as X.509 certificate digest when using the
+	  internal X.509/TLSv1 implementation
+	* fixed EAP-FAST PAC-Opaque padding (0.6.4 broke this for some peer
+	  identity lengths)
+	* fixed internal TLSv1 implementation for abbreviated handshake (used
+	  by EAP-FAST server)
+	* added support for setting VLAN ID for STAs based on local MAC ACL
+	  (accept_mac_file) as an alternative for RADIUS server-based
+	  configuration
+	* updated management frame protection to use IEEE 802.11w/D6.0
+	  (adds a new association ping to protect against unauthenticated
+	  authenticate or (re)associate request frames dropping association)
+	* added support for using SHA256-based stronger key derivation for WPA2
+	  (IEEE 802.11w)
+	* added new "driver wrapper" for RADIUS-only configuration
+	  (driver=none in hostapd.conf; CONFIG_DRIVER_NONE=y in .config)
+	* fixed WPA/RSN IE validation to verify that the proto (WPA vs. WPA2)
+	  is enabled in configuration
+	* changed EAP-FAST configuration to use separate fields for A-ID and
+	  A-ID-Info (eap_fast_a_id_info) to allow A-ID to be set to a fixed
+	  16-octet len binary value for better interoperability with some peer
+	  implementations; eap_fast_a_id is now configured as a hex string
+	* driver_nl80211: Updated to match the current Linux mac80211 AP mode
+	  configuration (wireless-testing.git and Linux kernel releases
+	  starting from 2.6.29)
+
+2008-08-10 - v0.6.4
+	* added peer identity into EAP-FAST PAC-Opaque and skip Phase 2
+	  Identity Request if identity is already known
+	* added support for EAP Sequences in EAP-FAST Phase 2
+	* added support for EAP-TNC (Trusted Network Connect)
+	  (this version implements the EAP-TNC method and EAP-TTLS/EAP-FAST
+	  changes needed to run two methods in sequence (IF-T) and the IF-IMV
+	  and IF-TNCCS interfaces from TNCS)
+	* added support for optional cryptobinding with PEAPv0
+	* added fragmentation support for EAP-TNC
+	* added support for fragmenting EAP-TTLS/PEAP/FAST Phase 2 (tunneled)
+	  data
+	* added support for opportunistic key caching (OKC)
+
+2008-02-22 - v0.6.3
+	* fixed Reassociation Response callback processing when using internal
+	  MLME (driver_{hostap,nl80211,test}.c)
+	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
+	* copy optional Proxy-State attributes into RADIUS response when acting
+	  as a RADIUS authentication server
+	* fixed EAPOL state machine to handle a case in which no response is
+	  received from the RADIUS authentication server; previous version
+	  could have triggered a crash in some cases after a timeout
+	* fixed EAP-SIM/AKA realm processing to allow decorated usernames to
+	  be used
+	* added a workaround for EAP-SIM/AKA peers that include incorrect null
+	  termination in the username
+	* fixed EAP-SIM/AKA protected result indication to include AT_COUNTER
+	  attribute in notification messages only when using fast
+	  reauthentication
+	* fixed EAP-SIM Start response processing for fast reauthentication
+	  case
+	* added support for pending EAP processing in EAP-{PEAP,TTLS,FAST}
+	  phase 2 to allow EAP-SIM and EAP-AKA to be used as the Phase 2 method
+
+2008-01-01 - v0.6.2
+	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
+	  lengths properly to avoid potential crash caused by invalid messages
+	* added data structure for storing allocated buffers (struct wpabuf);
+	  this does not affect hostapd usage, but many of the APIs changed
+	  and various interfaces (e.g., EAP) is not compatible with old
+	  versions
+	* added support for protecting EAP-AKA/Identity messages with
+	  AT_CHECKCODE (optional feature in RFC 4187)
+	* added support for protected result indication with AT_RESULT_IND for
+	  EAP-SIM and EAP-AKA (eap_sim_aka_result_ind=1)
+	* added support for configuring EAP-TTLS phase 2 non-EAP methods in
+	  EAP server configuration; previously all four were enabled for every
+	  phase 2 user, now all four are disabled by default and need to be
+	  enabled with new method names TTLS-PAP, TTLS-CHAP, TTLS-MSCHAP,
+	  TTLS-MSCHAPV2
+	* removed old debug printing mechanism and the related 'debug'
+	  parameter in the configuration file; debug verbosity is now set with
+	  -d (or -dd) command line arguments
+	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
+	  only shared key/password authentication is supported in this version
+
+2007-11-24 - v0.6.1
+	* added experimental, integrated TLSv1 server implementation with the
+	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
+	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
+	  .config); this can be useful, e.g., if the target system does not
+	  have a suitable TLS library and a minimal code size is required
+	* added support for EAP-FAST server method to the integrated EAP
+	  server
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-07.txt)
+	* added a new configuration parameter, rsn_pairwise, to allow different
+	  pairwise cipher suites to be enabled for WPA and RSN/WPA2
+	  (note: if wpa_pairwise differs from rsn_pairwise, the driver will
+	  either need to support this or will have to use the WPA/RSN IEs from
+	  hostapd; currently, the included madwifi and bsd driver interfaces do
+	  not have support for this)
+	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
+
+2007-05-28 - v0.6.0
+	* added experimental IEEE 802.11r/D6.0 support
+	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
+	* updated EAP-PSK to use the IANA-allocated EAP type 47
+	* fixed EAP-PSK bit ordering of the Flags field
+	* fixed configuration reloading (SIGHUP) to re-initialize WPA PSKs
+	  by reading wpa_psk_file [Bug 181]
+	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
+	* fixed IPv6 connection to RADIUS accounting server
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-04.txt)
+	* hlr_auc_gw: read GSM triplet file into memory and rotate through the
+	  entries instead of only using the same three triplets every time
+	  (this does not work properly with tests using multiple clients, but
+	  provides bit better triplet data for testing a single client; anyway,
+	  if a better quality triplets are needed, GSM-Milenage should be used
+	  instead of hardcoded triplet file)
+	* fixed EAP-MSCHAPv2 server to use a space between S and M parameters
+	  in Success Request [Bug 203]
+	* added support for sending EAP-AKA Notifications in error cases
+	* updated to use IEEE 802.11w/D2.0 for management frame protection
+	  (still experimental)
+	* RADIUS server: added support for processing duplicate messages
+	  (retransmissions from RADIUS client) by replying with the previous
+	  reply
+
+2006-11-24 - v0.5.6
+	* added support for configuring and controlling multiple BSSes per
+	  radio interface (bss=<ifname> in hostapd.conf); this is only
+	  available with Devicescape and test driver interfaces
+	* fixed PMKSA cache update in the end of successful RSN
+	  pre-authentication
+	* added support for dynamic VLAN configuration (i.e., selecting VLAN-ID
+	  for each STA based on RADIUS Access-Accept attributes); this requires
+	  VLAN support from the kernel driver/802.11 stack and this is
+	  currently only available with Devicescape and test driver interfaces
+	* driver_madwifi: fixed configuration of unencrypted modes (plaintext
+	  and IEEE 802.1X without WEP)
+	* removed STAKey handshake since PeerKey handshake has replaced it in
+	  IEEE 802.11ma and there are no known deployments of STAKey
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-01.txt)
+	* added preliminary implementation of IEEE 802.11w/D1.0 (management
+	  frame protection)
+	  (Note: this requires driver support to work properly.)
+	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
+	* hlr_auc_gw: added support for GSM-Milenage (for EAP-SIM)
+	* hlr_auc_gw: added support for reading per-IMSI Milenage keys and
+	  parameters from a text file to make it possible to implement proper
+	  GSM/UMTS authentication server for multiple SIM/USIM cards using
+	  EAP-SIM/EAP-AKA
+	* fixed session timeout processing with drivers that do not use
+	  ieee802_11.c (e.g., madwifi)
+
+2006-08-27 - v0.5.5
+	* added 'hostapd_cli new_sta <addr>' command for adding a new STA into
+	  hostapd (e.g., to initialize wired network authentication based on an
+	  external signal)
+	* fixed hostapd to add PMKID KDE into 4-Way Handshake Message 1 when
+	  using WPA2 even if PMKSA caching is not used
+	* added -P<pid file> argument for hostapd to write the current process
+	  id into a file
+	* added support for RADIUS Authentication Server MIB (RFC 2619)
+
+2006-06-20 - v0.5.4
+	* fixed nt_password_hash build [Bug 144]
+	* added PeerKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS) to replace STAKey handshake
+	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
+	  draft-clancy-emu-eap-shared-secret-00.txt)
+	* fixed a segmentation fault when RSN pre-authentication was completed
+	  successfully [Bug 152]
+
+2006-04-27 - v0.5.3
+	* do not build nt_password_hash and hlr_auc_gw by default to avoid
+	  requiring a TLS library for a successful build; these programs can be
+	  build with 'make nt_password_hash' and 'make hlr_auc_gw'
+	* added a new configuration option, eapol_version, that can be used to
+	  set EAPOL version to 1 (default is 2) to work around broken client
+	  implementations that drop EAPOL frames which use version number 2
+	  [Bug 89]
+	* added support for EAP-SAKE (no EAP method number allocated yet, so
+	  this is using the same experimental type 255 as EAP-PSK)
+	* fixed EAP-MSCHAPv2 message length validation
+
+2006-03-19 - v0.5.2
+	* fixed stdarg use in hostapd_logger(): if both stdout and syslog
+	  logging was enabled, hostapd could trigger a segmentation fault in
+	  vsyslog on some CPU -- C library combinations
+	* moved HLR/AuC gateway implementation for EAP-SIM/AKA into an external
+	  program to make it easier to use for implementing real SS7 gateway;
+	  eap_sim_db is not anymore used as a file name for GSM authentication
+	  triplets; instead, it is path to UNIX domain socket that will be used
+	  to communicate with the external gateway program (e.g., hlr_auc_gw)
+	* added example HLR/AuC gateway implementation, hlr_auc_gw, that uses
+	  local information (GSM authentication triplets from a text file and
+	  hardcoded AKA authentication data); this can be used to test EAP-SIM
+	  and EAP-AKA
+	* added Milenage algorithm (example 3GPP AKA algorithm) to hlr_auc_gw
+	  to make it possible to test EAP-AKA with real USIM cards (this is
+	  disabled by default; define AKA_USE_MILENAGE when building hlr_auc_gw
+	  to enable this)
+	* driver_madwifi: added support for getting station RSN IE from
+	  madwifi-ng svn r1453 and newer; this fixes RSN that was apparently
+	  broken with earlier change (r1357) in the driver
+	* changed EAP method registration to use a dynamic list of methods
+	  instead of a static list generated at build time
+	* fixed WPA message 3/4 not to encrypt Key Data field (WPA IE)
+	  [Bug 125]
+	* added ap_max_inactivity configuration parameter
+
+2006-01-29 - v0.5.1
+	* driver_test: added better support for multiple APs and STAs by using
+	  a directory with sockets that include MAC address for each device in
+	  the name (test_socket=DIR:/tmp/test)
+	* added support for EAP expanded type (vendor specific EAP methods)
+
+2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
+	* added experimental STAKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS); note: this is disabled by default in both
+	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
+	  and stakey=1)
+	* added support for EAP methods to use callbacks to external programs
+	  by buffering a pending request and processing it after the EAP method
+	  is ready to continue
+	* improved EAP-SIM database interface to allow external request to GSM
+	  HLR/AuC without blocking hostapd process
+	* added support for using EAP-SIM pseudonyms and fast re-authentication
+	* added support for EAP-AKA in the integrated EAP authenticator
+	* added support for matching EAP identity prefixes (e.g., "1"*) in EAP
+	  user database to allow EAP-SIM/AKA selection without extra roundtrip
+	  for EAP-Nak negotiation
+	* added support for storing EAP user password as NtPasswordHash instead
+	  of plaintext password when using MSCHAP or MSCHAPv2 for
+	  authentication (hash:<16-octet hex value>); added nt_password_hash
+	  tool for hashing password to generate NtPasswordHash
+
+2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
+	* driver_wired: fixed EAPOL sending to optionally use PAE group address
+	  as the destination instead of supplicant MAC address; this is
+	  disabled by default, but should be enabled with use_pae_group_addr=1
+	  in configuration file if the wired interface is used by only one
+	  device at the time (common switch configuration)
+	* driver_madwifi: configure driver to use TKIP countermeasures in order
+	  to get correct behavior (IEEE 802.11 association failing; previously,
+	  association succeeded, but hostpad forced disassociation immediately)
+	* driver_madwifi: added support for madwifi-ng
+
+2005-10-27 - v0.4.6
+	* added support for replacing user identity from EAP with RADIUS
+	  User-Name attribute from Access-Accept message, if that is included,
+	  for the RADIUS accounting messages (e.g., for EAP-PEAP/TTLS to get
+	  tunneled identity into accounting messages when the RADIUS server
+	  does not support better way of doing this with Class attribute)
+	* driver_madwifi: fixed EAPOL packet receive for configuration where
+	  ath# is part of a bridge interface
+	* added a configuration file and log analyzer script for logwatch
+	* fixed EAPOL state machine step function to process all state
+	  transitions before processing new events; this resolves a race
+	  condition in which EAPOL-Start message could trigger hostapd to send
+	  two EAP-Response/Identity frames to the authentication server
+
+2005-09-25 - v0.4.5
+	* added client CA list to the TLS certificate request in order to make
+	  it easier for the client to select which certificate to use
+	* added experimental support for EAP-PSK
+	* added support for WE-19 (hostap, madwifi)
+
+2005-08-21 - v0.4.4
+	* fixed build without CONFIG_RSN_PREAUTH
+	* fixed FreeBSD build
+
+2005-06-26 - v0.4.3
+	* fixed PMKSA caching to copy User-Name and Class attributes so that
+	  RADIUS accounting gets correct information
+	* start RADIUS accounting only after successful completion of WPA
+	  4-Way Handshake if WPA-PSK is used
+	* fixed PMKSA caching for the case where STA (re)associates without
+	  first disassociating
+
+2005-06-12 - v0.4.2
+	* EAP-PAX is now registered as EAP type 46
+	* fixed EAP-PAX MAC calculation
+	* fixed EAP-PAX CK and ICK key derivation
+	* renamed eap_authenticator configuration variable to eap_server to
+	  better match with RFC 3748 (EAP) terminology
+	* driver_test: added support for testing hostapd with wpa_supplicant
+	  by using test driver interface without any kernel drivers or network
+	  cards
+
+2005-05-22 - v0.4.1
+	* fixed RADIUS server initialization when only auth or acct server
+	  is configured and the other one is left empty
+	* driver_madwifi: added support for RADIUS accounting
+	* driver_madwifi: added preliminary support for compiling against 'BSD'
+	  branch of madwifi CVS tree
+	* driver_madwifi: fixed pairwise key removal to allow WPA reauth
+	  without disassociation
+	* added support for reading additional certificates from PKCS#12 files
+	  and adding them to the certificate chain
+	* fixed RADIUS Class attribute processing to only use Access-Accept
+	  packets to update Class; previously, other RADIUS authentication
+	  packets could have cleared Class attribute
+	* added support for more than one Class attribute in RADIUS packets
+	* added support for verifying certificate revocation list (CRL) when
+	  using integrated EAP authenticator for EAP-TLS; new hostapd.conf
+	  options 'check_crl'; CRL must be included in the ca_cert file for now
+
+2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
+	* added support for including network information into
+	  EAP-Request/Identity message (ASCII-0 (nul) in eap_message)
+	  (e.g., to implement draft-adrange-eap-network-discovery-07.txt)
+	* fixed a bug which caused some RSN pre-authentication cases to use
+	  freed memory and potentially crash hostapd
+	* fixed private key loading for cases where passphrase is not set
+	* added support for sending TLS alerts and aborting authentication
+	  when receiving a TLS alert
+	* fixed WPA2 to add PMKSA cache entry when using integrated EAP
+	  authenticator
+	* fixed PMKSA caching (EAP authentication was not skipped correctly
+	  with the new state machine changes from IEEE 802.1X draft)
+	* added support for RADIUS over IPv6; own_ip_addr, auth_server_addr,
+	  and acct_server_addr can now be IPv6 addresses (CONFIG_IPV6=y needs
+	  to be added to .config to include IPv6 support); for RADIUS server,
+	  radius_server_ipv6=1 needs to be set in hostapd.conf and addresses
+	  in RADIUS clients file can then use IPv6 format
+	* added experimental support for EAP-PAX
+	* replaced hostapd control interface library (hostapd_ctrl.[ch]) with
+	  the same implementation that wpa_supplicant is using (wpa_ctrl.[ch])
+
+2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
+
+2005-01-23 - v0.3.5
+	* added support for configuring a forced PEAP version based on the
+	  Phase 1 identity
+	* fixed PEAPv1 to use tunneled EAP-Success/Failure instead of EAP-TLV
+	  to terminate authentication
+	* fixed EAP identifier duplicate processing with the new IEEE 802.1X
+	  draft
+	* clear accounting data in the driver when starting a new accounting
+	  session
+	* driver_madwifi: filter wireless events based on ifindex to allow more
+	  than one network interface to be used
+	* fixed WPA message 2/4 processing not to cancel timeout for TimeoutEvt
+	  setting if the packet does not pass MIC verification (e.g., due to
+	  incorrect PSK); previously, message 1/4 was not tried again if an
+	  invalid message 2/4 was received
+	* fixed reconfiguration of RADIUS client retransmission timer when
+	  adding a new message to the pending list; previously, timer was not
+	  updated at this point and if there was a pending message with long
+	  time for the next retry, the new message needed to wait that long for
+	  its first retry, too
+
+2005-01-09 - v0.3.4
+	* added support for configuring multiple allowed EAP types for Phase 2
+	  authentication (EAP-PEAP, EAP-TTLS)
+	* fixed EAPOL-Start processing to trigger WPA reauthentication
+	  (previously, only EAPOL authentication was done)
+
+2005-01-02 - v0.3.3
+	* added support for EAP-PEAP in the integrated EAP authenticator
+	* added support for EAP-GTC in the integrated EAP authenticator
+	* added support for configuring list of EAP methods for Phase 1 so that
+	  the integrated EAP authenticator can, e.g., use the wildcard entry
+	  for EAP-TLS and EAP-PEAP
+	* added support for EAP-TTLS in the integrated EAP authenticator
+	* added support for EAP-SIM in the integrated EAP authenticator
+	* added support for using hostapd as a RADIUS authentication server
+	  with the integrated EAP authenticator taking care of EAP
+	  authentication (new hostapd.conf options: radius_server_clients and
+	  radius_server_auth_port); this is not included in default build; use
+	  CONFIG_RADIUS_SERVER=y in .config to include
+
+2004-12-19 - v0.3.2
+	* removed 'daemonize' configuration file option since it has not really
+	  been used at all for more than year
+	* driver_madwifi: fixed group key setup and added get_ssid method
+	* added support for EAP-MSCHAPv2 in the integrated EAP authenticator
+
+2004-12-12 - v0.3.1
+	* added support for integrated EAP-TLS authentication (new hostapd.conf
+	  variables: ca_cert, server_cert, private_key, private_key_passwd);
+	  this enabled dynamic keying (WPA2/WPA/IEEE 802.1X/WEP) without
+	  external RADIUS server
+	* added support for reading PKCS#12 (PFX) files (as a replacement for
+	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
+
+2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
+	* added support for Acct-{Input,Output}-Gigawords
+	* added support for Event-Timestamp (in RADIUS Accounting-Requests)
+	* added support for RADIUS Authentication Client MIB (RFC2618)
+	* added support for RADIUS Accounting Client MIB (RFC2620)
+	* made EAP re-authentication period configurable (eap_reauth_period)
+	* fixed EAPOL reauthentication to trigger WPA/WPA2 reauthentication
+	* fixed EAPOL state machine to stop if STA is removed during
+	  eapol_sm_step(); this fixes at least one segfault triggering bug with
+	  IEEE 802.11i pre-authentication
+	* added support for multiple WPA pre-shared keys (e.g., one for each
+	  client MAC address or keys shared by a group of clients);
+	  new hostapd.conf field wpa_psk_file for setting path to a text file
+	  containing PSKs, see hostapd.wpa_psk for an example
+	* added support for multiple driver interfaces to allow hostapd to be
+	  used with other drivers
+	* added wired authenticator driver interface (driver=wired in
+	  hostapd.conf, see wired.conf for example configuration)
+	* added madwifi driver interface (driver=madwifi in hostapd.conf, see
+	  madwifi.conf for example configuration; Note: include files from
+	  madwifi project is needed for building and a configuration file,
+	  .config, needs to be created in hostapd directory with
+	  CONFIG_DRIVER_MADWIFI=y to include this driver interface in hostapd
+	  build)
+	* fixed an alignment issue that could cause SHA-1 to fail on some
+	  platforms (e.g., Intel ixp425 with a compiler that does not 32-bit
+	  align variables)
+	* fixed RADIUS reconnection after an error in sending interim
+	  accounting packets
+	* added hostapd control interface for external programs and an example
+	  CLI, hostapd_cli (like wpa_cli for wpa_supplicant)
+	* started adding dot11, dot1x, radius MIBs ('hostapd_cli mib',
+	  'hostapd_cli sta <addr>')
+	* finished update from IEEE 802.1X-2001 to IEEE 802.1X-REV (now d11)
+	* added support for strict GTK rekeying (wpa_strict_rekey in
+	  hostapd.conf)
+	* updated IAPP to use UDP port 3517 and multicast address 224.0.1.178
+	  (instead of broadcast) for IAPP ADD-notify (moved from draft 3 to
+	  IEEE 802.11F-2003)
+	* added Prism54 driver interface (driver=prism54 in hostapd.conf;
+	  note: .config needs to be created in hostapd directory with
+	  CONFIG_DRIVER_PRISM54=y to include this driver interface in hostapd
+	  build)
+	* dual-licensed hostapd (GPLv2 and BSD licenses)
+	* fixed RADIUS accounting to generate a new session id for cases where
+	  a station reassociates without first being complete deauthenticated
+	* fixed STA disassociation handler to mark next timeout state to
+	  deauthenticate the station, i.e., skip long wait for inactivity poll
+	  and extra disassociation, if the STA disassociates without
+	  deauthenticating
+	* added integrated EAP authenticator that can be used instead of
+	  external RADIUS authentication server; currently, only EAP-MD5 is
+	  supported, so this cannot yet be used for key distribution; the EAP
+	  method interface is generic, though, so adding new EAP methods should
+	  be straightforward; new hostapd.conf variables: 'eap_authenticator'
+	  and 'eap_user_file'; this obsoletes "minimal authentication server"
+	  ('minimal_eap' in hostapd.conf) which is now removed
+	* added support for FreeBSD and driver interface for the BSD net80211
+	  layer (driver=bsd in hostapd.conf and CONFIG_DRIVER_BSD=y in
+	  .config); please note that some of the required kernel mods have not
+	  yet been committed
+
+2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
+	* fixed some accounting cases where Accounting-Start was sent when
+	  IEEE 802.1X port was being deauthorized
+
+2004-06-20 - v0.2.3
+	* modified RADIUS client to re-connect the socket in case of certain
+	  error codes that are generated when a network interface state is
+	  changes (e.g., when IP address changes or the interface is set UP)
+	* fixed couple of cases where EAPOL state for a station was freed
+	  twice causing a segfault for hostapd
+	* fixed couple of bugs in processing WPA deauthentication (freed data
+	  was used)
+
+2004-05-31 - v0.2.2
+	* fixed WPA/WPA2 group rekeying to use key index correctly (GN/GM)
+	* fixed group rekeying to send zero TSC in EAPOL-Key messages to fix
+	  cases where STAs dropped multicast frames as replay attacks
+	* added support for copying RADIUS Attribute 'Class' from
+	  authentication messages into accounting messages
+	* send canned EAP failure if RADIUS server sends Access-Reject without
+	  EAP message (previously, Supplicant was not notified in this case)
+	* fixed mixed WPA-PSK and WPA-EAP mode to work with WPA-PSK (i.e., do
+	  not start EAPOL state machines if the STA selected to use WPA-PSK)
+
+2004-05-06 - v0.2.1
+	* added WPA and IEEE 802.11i/RSN (WPA2) Authenticator functionality
+	  - based on IEEE 802.11i/D10.0 but modified to interoperate with WPA
+	    (i.e., IEEE 802.11i/D3.0)
+	  - supports WPA-only, RSN-only, and mixed WPA/RSN mode
+	  - both WPA-PSK and WPA-RADIUS/EAP are supported
+	  - PMKSA caching and pre-authentication
+	  - new hostapd.conf variables: wpa, wpa_psk, wpa_passphrase,
+	    wpa_key_mgmt, wpa_pairwise, wpa_group_rekey, wpa_gmk_rekey,
+	    rsn_preauth, rsn_preauth_interfaces
+	* fixed interim accounting to remove any pending accounting messages
+	  to the STA before sending a new one
+
+2004-02-15 - v0.2.0
+	* added support for Acct-Interim-Interval:
+	  - draft-ietf-radius-acct-interim-01.txt
+	  - use Acct-Interim-Interval attribute from Access-Accept if local
+	    'radius_acct_interim_interval' is not set
+	  - allow different update intervals for each STA
+	* fixed event loop to call signal handlers only after returning from
+	  the real signal handler
+	* reset sta->timeout_next after successful association to make sure
+	  that the previously registered inactivity timer will not remove the
+	  STA immediately (e.g., if STA deauthenticates and re-associates
+	  before the timer is triggered).
+	* added new hostapd.conf variable, nas_identifier, that can be used to
+	  add an optional RADIUS Attribute, NAS-Identifier, into authentication
+	  and accounting messages
+	* added support for Accounting-On and Accounting-Off messages
+	* fixed accounting session handling to send Accounting-Start only once
+	  per session and not to send Accounting-Stop if the session was not
+	  initialized properly
+	* fixed Accounting-Stop statistics in cases where the message was
+	  previously sent after the kernel entry for the STA (and/or IEEE
+	  802.1X data) was removed
+
+
+Note:
+
+Older changes up to and including v0.1.0 are included in the ChangeLog
+of the Host AP driver.

+Introduction
+============
+
+Originally, hostapd was an optional user space component for Host AP
+driver. It adds more features to the basic IEEE 802.11 management
+included in the kernel driver: using external RADIUS authentication
+server for MAC address based access control, IEEE 802.1X Authenticator
+and dynamic WEP keying, RADIUS accounting, WPA/WPA2 (IEEE 802.11i/RSN)
+Authenticator and dynamic TKIP/CCMP keying.
+
+The current version includes support for other drivers, an integrated
+EAP server (i.e., allow full authentication without requiring
+an external RADIUS authentication server), and RADIUS authentication
+server for EAP authentication.
+
+
+Requirements
+------------
+
+Current hardware/software requirements:
+- drivers:
+	Host AP driver for Prism2/2.5/3.
+	(http://hostap.epitest.fi/)
+	Please note that station firmware version needs to be 1.7.0 or newer
+	to work in WPA mode.
+
+	madwifi driver for cards based on Atheros chip set (ar521x)
+	(http://sourceforge.net/projects/madwifi/)
+	Please note that you will need to add the correct path for
+	madwifi driver root directory in .config (see defconfig file for
+	an example: CFLAGS += -I<path>)
+
+	mac80211-based drivers that support AP mode (with driver=nl80211).
+	This includes drivers for Atheros (ath9k) and Broadcom (b43)
+	chipsets.
+
+	Any wired Ethernet driver for wired IEEE 802.1X authentication
+	(experimental code)
+
+	FreeBSD -current (with some kernel mods that have not yet been
+	committed when hostapd v0.3.0 was released)
+	BSD net80211 layer (e.g., Atheros driver)
+
+
+Build configuration
+-------------------
+
+In order to be able to build hostapd, you will need to create a build
+time configuration file, .config that selects which optional
+components are included. See defconfig file for example configuration
+and list of available options.
+
+
+
+IEEE 802.1X
+===========
+
+IEEE Std 802.1X-2001 is a standard for port-based network access
+control. In case of IEEE 802.11 networks, a "virtual port" is used
+between each associated station and the AP. IEEE 802.11 specifies
+minimal authentication mechanism for stations, whereas IEEE 802.1X
+introduces a extensible mechanism for authenticating and authorizing
+users.
+
+IEEE 802.1X uses elements called Supplicant, Authenticator, Port
+Access Entity, and Authentication Server. Supplicant is a component in
+a station and it performs the authentication with the Authentication
+Server. An access point includes an Authenticator that relays the packets
+between a Supplicant and an Authentication Server. In addition, it has a
+Port Access Entity (PAE) with Authenticator functionality for
+controlling the virtual port authorization, i.e., whether to accept
+packets from or to the station.
+
+IEEE 802.1X uses Extensible Authentication Protocol (EAP). The frames
+between a Supplicant and an Authenticator are sent using EAP over LAN
+(EAPOL) and the Authenticator relays these frames to the Authentication
+Server (and similarly, relays the messages from the Authentication
+Server to the Supplicant). The Authentication Server can be colocated with the
+Authenticator, in which case there is no need for additional protocol
+for EAP frame transmission. However, a more common configuration is to
+use an external Authentication Server and encapsulate EAP frame in the
+frames used by that server. RADIUS is suitable for this, but IEEE
+802.1X would also allow other mechanisms.
+
+Host AP driver includes PAE functionality in the kernel driver. It
+is a relatively simple mechanism for denying normal frames going to
+or coming from an unauthorized port. PAE allows IEEE 802.1X related
+frames to be passed between the Supplicant and the Authenticator even
+on an unauthorized port.
+
+User space daemon, hostapd, includes Authenticator functionality. It
+receives 802.1X (EAPOL) frames from the Supplicant using the wlan#ap
+device that is also used with IEEE 802.11 management frames. The
+frames to the Supplicant are sent using the same device.
+
+The normal configuration of the Authenticator would use an external
+Authentication Server. hostapd supports RADIUS encapsulation of EAP
+packets, so the Authentication Server should be a RADIUS server, like
+FreeRADIUS (http://www.freeradius.org/). The Authenticator in hostapd
+relays the frames between the Supplicant and the Authentication
+Server. It also controls the PAE functionality in the kernel driver by
+controlling virtual port authorization, i.e., station-AP
+connection, based on the IEEE 802.1X state.
+
+When a station would like to use the services of an access point, it
+will first perform IEEE 802.11 authentication. This is normally done
+with open systems authentication, so there is no security. After
+this, IEEE 802.11 association is performed. If IEEE 802.1X is
+configured to be used, the virtual port for the station is set in
+Unauthorized state and only IEEE 802.1X frames are accepted at this
+point. The Authenticator will then ask the Supplicant to authenticate
+with the Authentication Server. After this is completed successfully,
+the virtual port is set to Authorized state and frames from and to the
+station are accepted.
+
+Host AP configuration for IEEE 802.1X
+-------------------------------------
+
+The user space daemon has its own configuration file that can be used to
+define AP options. Distribution package contains an example
+configuration file (hostapd/hostapd.conf) that can be used as a basis
+for configuration. It includes examples of all supported configuration
+options and short description of each option. hostapd should be started
+with full path to the configuration file as the command line argument,
+e.g., './hostapd /etc/hostapd.conf'. If you have more that one wireless
+LAN card, you can use one hostapd process for multiple interfaces by
+giving a list of configuration files (one per interface) in the command
+line.
+
+hostapd includes a minimal co-located IEEE 802.1X server which can be
+used to test IEEE 802.1X authentication. However, it should not be
+used in normal use since it does not provide any security. This can be
+configured by setting ieee8021x and minimal_eap options in the
+configuration file.
+
+An external Authentication Server (RADIUS) is configured with
+auth_server_{addr,port,shared_secret} options. In addition,
+ieee8021x and own_ip_addr must be set for this mode. With such
+configuration, the co-located Authentication Server is not used and EAP
+frames will be relayed using EAPOL between the Supplicant and the
+Authenticator and RADIUS encapsulation between the Authenticator and
+the Authentication Server. Other than this, the functionality is similar
+to the case with the co-located Authentication Server.
+
+Authentication Server and Supplicant
+------------------------------------
+
+Any RADIUS server supporting EAP should be usable as an IEEE 802.1X
+Authentication Server with hostapd Authenticator. FreeRADIUS
+(http://www.freeradius.org/) has been successfully tested with hostapd
+Authenticator and both Xsupplicant (http://www.open1x.org) and Windows
+XP Supplicants. EAP/TLS was used with Xsupplicant and
+EAP/MD5-Challenge with Windows XP.
+
+http://www.missl.cs.umd.edu/wireless/eaptls/ has useful information
+about using EAP/TLS with FreeRADIUS and Xsupplicant (just replace
+Cisco access point with Host AP driver, hostapd daemon, and a Prism2
+card ;-). http://www.freeradius.org/doc/EAP-MD5.html has information
+about using EAP/MD5 with FreeRADIUS, including instructions for WinXP
+configuration. http://www.denobula.com/EAPTLS.pdf has a HOWTO on
+EAP/TLS use with WinXP Supplicant.
+
+Automatic WEP key configuration
+-------------------------------
+
+EAP/TLS generates a session key that can be used to send WEP keys from
+an AP to authenticated stations. The Authenticator in hostapd can be
+configured to automatically select a random default/broadcast key
+(shared by all authenticated stations) with wep_key_len_broadcast
+option (5 for 40-bit WEP or 13 for 104-bit WEP). In addition,
+wep_key_len_unicast option can be used to configure individual unicast
+keys for stations. This requires support for individual keys in the
+station driver.
+
+WEP keys can be automatically updated by configuring rekeying. This
+will improve security of the network since same WEP key will only be
+used for a limited period of time. wep_rekey_period option sets the
+interval for rekeying in seconds.
+
+
+WPA/WPA2
+========
+
+Features
+--------
+
+Supported WPA/IEEE 802.11i features:
+- WPA-PSK ("WPA-Personal")
+- WPA with EAP (e.g., with RADIUS authentication server) ("WPA-Enterprise")
+- key management for CCMP, TKIP, WEP104, WEP40
+- RSN/WPA2 (IEEE 802.11i), including PMKSA caching and pre-authentication
+
+WPA
+---
+
+The original security mechanism of IEEE 802.11 standard was not
+designed to be strong and has proved to be insufficient for most
+networks that require some kind of security. Task group I (Security)
+of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
+to address the flaws of the base standard and has in practice
+completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
+802.11 standard was approved in June 2004 and this amendment is likely
+to be published in July 2004.
+
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
+IEEE 802.11i work (draft 3.0) to define a subset of the security
+enhancements that can be implemented with existing wlan hardware. This
+is called Wi-Fi Protected Access<TM> (WPA). This has now become a
+mandatory component of interoperability testing and certification done
+by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
+site (http://www.wi-fi.org/OpenSection/protected_access.asp).
+
+IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
+for protecting wireless networks. WEP uses RC4 with 40-bit keys,
+24-bit initialization vector (IV), and CRC32 to protect against packet
+forgery. All these choices have proven to be insufficient: key space is
+too small against current attacks, RC4 key scheduling is insufficient
+(beginning of the pseudorandom stream should be skipped), IV space is
+too small and IV reuse makes attacks easier, there is no replay
+protection, and non-keyed authentication does not protect against bit
+flipping packet data.
+
+WPA is an intermediate solution for the security issues. It uses
+Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
+compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+
+Keys can be managed using two different mechanisms. WPA can either use
+an external authentication server (e.g., RADIUS) and EAP just like
+IEEE 802.1X is using or pre-shared keys without need for additional
+servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
+respectively. Both mechanisms will generate a master session key for
+the Authenticator (AP) and Supplicant (client station).
+
+WPA implements a new key handshake (4-Way Handshake and Group Key
+Handshake) for generating and exchanging data encryption keys between
+the Authenticator and Supplicant. This handshake is also used to
+verify that both Authenticator and Supplicant know the master session
+key. These handshakes are identical regardless of the selected key
+management mechanism (only the method for generating master session
+key changes).
+
+
+IEEE 802.11i / WPA2
+-------------------
+
+The design for parts of IEEE 802.11i that were not included in WPA has
+finished (May 2004) and this amendment to IEEE 802.11 was approved in
+June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
+version of WPA called WPA2. This includes, e.g., support for more
+robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
+to replace TKIP and optimizations for handoff (reduced number of

+
+Some wireless LAN vendors are already providing support for CCMP in
+their WPA products. There is no "official" interoperability
+certification for CCMP and/or mixed modes using both TKIP and CCMP, so
+some interoperability issues can be expected even though many

+hostapd and Wi-Fi Protected Setup (WPS)
+=======================================
+
+This document describes how the WPS implementation in hostapd can be
+configured and how an external component on an AP (e.g., web UI) is
+used to enable enrollment of client devices.
+
+
+Introduction to WPS
+-------------------
+
+Wi-Fi Protected Setup (WPS) is a mechanism for easy configuration of a
+wireless network. It allows automated generation of random keys (WPA
+passphrase/PSK) and configuration of an access point and client
+devices. WPS includes number of methods for setting up connections
+with PIN method and push-button configuration (PBC) being the most
+commonly deployed options.
+
+While WPS can enable more home networks to use encryption in the
+wireless network, it should be noted that the use of the PIN and
+especially PBC mechanisms for authenticating the initial key setup is
+not very secure. As such, use of WPS may not be suitable for
+environments that require secure network access without chance for
+allowing outsiders to gain access during the setup phase.
+
+WPS uses following terms to describe the entities participating in the
+network setup:
+- access point: the WLAN access point
+- Registrar: a device that control a network and can authorize
+  addition of new devices); this may be either in the AP ("internal
+  Registrar") or in an external device, e.g., a laptop, ("external
+  Registrar")
+- Enrollee: a device that is being authorized to use the network
+
+It should also be noted that the AP and a client device may change
+roles (i.e., AP acts as an Enrollee and client device as a Registrar)
+when WPS is used to configure the access point.
+
+
+More information about WPS is available from Wi-Fi Alliance:
+http://www.wi-fi.org/wifi-protected-setup
+
+
+hostapd implementation
+----------------------
+
+hostapd includes an optional WPS component that can be used as an
+internal WPS Registrar to manage addition of new WPS enabled clients
+to the network. In addition, WPS Enrollee functionality in hostapd can
+be used to allow external WPS Registrars to configure the access
+point, e.g., for initial network setup. In addition, hostapd can proxy a
+WPS registration between a wireless Enrollee and an external Registrar
+(e.g., Microsoft Vista or Atheros JumpStart) with UPnP.
+
+
+hostapd configuration
+---------------------
+
+WPS is an optional component that needs to be enabled in hostapd build
+configuration (.config). Here is an example configuration that
+includes WPS support and uses madwifi driver interface:
+
+CONFIG_DRIVER_MADWIFI=y
+CFLAGS += -I/usr/src/madwifi-0.9.3
+CONFIG_WPS=y
+CONFIG_WPS2=y
+CONFIG_WPS_UPNP=y
+
+Following parameter can be used to enable support for NFC config method:
+
+CONFIG_WPS_NFC=y
+
+
+Following section shows an example runtime configuration
+(hostapd.conf) that enables WPS:
+
+# Configure the driver and network interface
+driver=madwifi
+interface=ath0
+
+# WPA2-Personal configuration for the AP
+ssid=wps-test
+wpa=2
+wpa_key_mgmt=WPA-PSK
+wpa_pairwise=CCMP
+# Default WPA passphrase for legacy (non-WPS) clients
+wpa_passphrase=12345678
+# Enable random per-device PSK generation for WPS clients
+# Please note that the file has to exists for hostapd to start (i.e., create an
+# empty file as a starting point).
+wpa_psk_file=/etc/hostapd.psk
+
+# Enable control interface for PBC/PIN entry
+ctrl_interface=/var/run/hostapd
+
+# Enable internal EAP server for EAP-WSC (part of Wi-Fi Protected Setup)
+eap_server=1
+
+# WPS configuration (AP configured, do not allow external WPS Registrars)
+wps_state=2
+ap_setup_locked=1
+# If UUID is not configured, it will be generated based on local MAC address.
+uuid=87654321-9abc-def0-1234-56789abc0000
+wps_pin_requests=/var/run/hostapd.pin-req
+device_name=Wireless AP
+manufacturer=Company
+model_name=WAP
+model_number=123
+serial_number=12345
+device_type=6-0050F204-1
+os_version=01020300
+config_methods=label display push_button keypad
+
+# if external Registrars are allowed, UPnP support could be added:
+#upnp_iface=br0
+#friendly_name=WPS Access Point
+
+
+External operations
+-------------------
+
+WPS requires either a device PIN code (usually, 8-digit number) or a
+pushbutton event (for PBC) to allow a new WPS Enrollee to join the
+network. hostapd uses the control interface as an input channel for
+these events.
+
+The PIN value used in the commands must be processed by an UI to
+remove non-digit characters and potentially, to verify the checksum
+digit. "hostapd_cli wps_check_pin <PIN>" can be used to do such
+processing. It returns FAIL if the PIN is invalid, or FAIL-CHECKSUM if
+the checksum digit is incorrect, or the processed PIN (non-digit
+characters removed) if the PIN is valid.
+
+When a client device (WPS Enrollee) connects to hostapd (WPS
+Registrar) in order to start PIN mode negotiation for WPS, an
+identifier (Enrollee UUID) is sent. hostapd will need to be configured
+with a device password (PIN) for this Enrollee. This is an operation
+that requires user interaction (assuming there are no pre-configured
+PINs on the AP for a set of Enrollee).
+
+The PIN request with information about the device is appended to the
+wps_pin_requests file (/var/run/hostapd.pin-req in this example). In
+addition, hostapd control interface event is sent as a notification of
+a new device. The AP could use, e.g., a web UI for showing active
+Enrollees to the user and request a PIN for an Enrollee.
+
+The PIN request file has one line for every Enrollee that connected to
+the AP, but for which there was no PIN. Following information is
+provided for each Enrollee (separated with tabulators):
+- timestamp (seconds from 1970-01-01)
+- Enrollee UUID
+- MAC address
+- Device name
+- Manufacturer
+- Model Name
+- Model Number
+- Serial Number
+- Device category
+
+Example line in the /var/run/hostapd.pin-req file:
+1200188391	53b63a98-d29e-4457-a2ed-094d7e6a669c	Intel(R) Centrino(R)	Intel Corporation	Intel(R) Centrino(R)	-	-	1-0050F204-1
+
+Control interface data:
+WPS-PIN-NEEDED [UUID-E|MAC Address|Device Name|Manufacturer|Model Name|Model Number|Serial Number|Device Category]
+For example:
+<2>WPS-PIN-NEEDED [53b63a98-d29e-4457-a2ed-094d7e6a669c|02:12:34:56:78:9a|Device|Manuf|Model|Model Number|Serial Number|1-0050F204-1]
+
+When the user enters a PIN for a pending Enrollee, e.g., on the web
+UI), hostapd needs to be notified of the new PIN over the control
+interface. This can be done either by using the UNIX domain socket
+-based control interface directly (src/common/wpa_ctrl.c provides
+helper functions for using the interface) or by calling hostapd_cli.
+
+Example command to add a PIN (12345670) for an Enrollee:
+
+hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c 12345670
+
+If the UUID-E is not available (e.g., Enrollee waits for the Registrar
+to be selected before connecting), wildcard UUID may be used to allow
+the PIN to be used once with any UUID:
+
+hostapd_cli wps_pin any 12345670
+
+To reduce likelihood of PIN being used with other devices or of
+forgetting an active PIN available for potential attackers, expiration
+time in seconds can be set for the new PIN (value 0 indicates no
+expiration):
+
+hostapd_cli wps_pin any 12345670 300
+
+If the MAC address of the enrollee is known, it should be configured
+to allow the AP to advertise list of authorized enrollees:
+
+hostapd_cli wps_pin 53b63a98-d29e-4457-a2ed-094d7e6a669c \
+	12345670 300 00:11:22:33:44:55
+
+
+After this, the Enrollee can connect to the AP again and complete WPS
+negotiation. At that point, a new, random WPA PSK is generated for the
+client device and the client can then use that key to connect to the
+AP to access the network.
+
+
+If the AP includes a pushbutton, WPS PBC mode can be used. It is
+enabled by pushing a button on both the AP and the client at about the
+same time (2 minute window). hostapd needs to be notified about the AP
+button pushed event over the control interface, e.g., by calling
+hostapd_cli:
+
+hostapd_cli wps_pbc
+
+At this point, the client has two minutes to complete WPS negotiation
+which will generate a new WPA PSK in the same way as the PIN method
+described above.
+
+
+When an external Registrar is used, the AP can act as an Enrollee and
+use its AP PIN. A static AP PIN (e.g., one one a label in the AP
+device) can be configured in hostapd.conf (ap_pin parameter). A more
+secure option is to use hostapd_cli wps_ap_pin command to enable the
+AP PIN only based on user action (and even better security by using a
+random AP PIN for each session, i.e., by using "wps_ap_pin random"
+command with a timeout value). Following commands are available for
+managing the dynamic AP PIN operations:
+
+hostapd_cli wps_ap_pin disable
+- disable AP PIN (i.e., do not allow external Registrars to use it to
+  learn the current AP settings or to reconfigure the AP)
+
+hostapd_cli wps_ap_pin random [timeout]
+- generate a random AP PIN and enable it
+- if the optional timeout parameter is given, the AP PIN will be enabled
+  for the specified number of seconds
+
+hostapd_cli wps_ap_pin get
+- fetch the current AP PIN
+
+hostapd_cli wps_ap_pin set <PIN> [timeout]
+- set the AP PIN and enable it
+- if the optional timeout parameter is given, the AP PIN will be enabled
+  for the specified number of seconds
+
+hostapd_cli get_config
+- display the current configuration
+
+hostapd_cli wps_config <new SSID> <auth> <encr> <new key>
+examples:
+  hostapd_cli wps_config testing WPA2PSK CCMP 12345678
+  hostapd_cli wps_config "no security" OPEN NONE ""
+
+<auth> must be one of the following: OPEN WPAPSK WPA2PSK
+<encr> must be one of the following: NONE WEP TKIP CCMP
+
+
+Credential generation and configuration changes
+-----------------------------------------------
+
+By default, hostapd generates credentials for Enrollees and processing
+AP configuration updates internally. However, it is possible to
+control these operations from external programs, if desired.
+
+The internal credential generation can be disabled with
+skip_cred_build=1 option in the configuration. extra_cred option will
+then need to be used to provide pre-configured Credential attribute(s)
+for hostapd to use. The exact data from this binary file will be sent,
+i.e., it will have to include valid WPS attributes. extra_cred can
+also be used to add additional networks if the Registrar is used to
+configure credentials for multiple networks.
+
+Processing of received configuration updates can be disabled with
+wps_cred_processing=1 option. When this is used, an external program
+is responsible for creating hostapd configuration files and processing
+configuration updates based on messages received from hostapd over
+control interface. This will also include the initial configuration on
+first successful registration if the AP is initially set in
+unconfigured state.
+
+Following control interface messages are sent out for external programs:
+
+WPS-REG-SUCCESS <Enrollee MAC address <UUID-E>
+For example:
+<2>WPS-REG-SUCCESS 02:66:a0:ee:17:27 2b7093f1-d6fb-5108-adbb-bea66bb87333
+
+This can be used to trigger change from unconfigured to configured
+state (random configuration based on the first successful WPS
+registration). In addition, this can be used to update AP UI about the
+status of WPS registration progress.
+
+
+WPS-NEW-AP-SETTINGS <hexdump of AP Setup attributes>
+For example:
+<2>WPS-NEW-AP-SETTINGS 10260001011045000c6a6b6d2d7770732d74657374100300020020100f00020008102700403065346230343536633236366665306433396164313535346131663462663731323433376163666462376633393965353466316631623032306164343438623510200006024231cede15101e000844
+
+This can be used to update the externally stored AP configuration and
+then update hostapd configuration (followed by restarting of hostapd).
+
+
+WPS with NFC
+------------
+
+WPS can be used with NFC-based configuration method. An NFC tag
+containing a password token from the Enrollee can be used to
+authenticate the connection instead of the PIN. In addition, an NFC tag
+with a configuration token can be used to transfer AP settings without
+going through the WPS protocol.
+
+When the AP acts as an Enrollee, a local NFC tag with a password token
+can be used by touching the NFC interface of an external Registrar. The
+wps_nfc_token command is used to manage use of the NFC password token
+from the AP. "wps_nfc_token enable" enables the use of the AP's NFC
+password token (in place of AP PIN) and "wps_nfc_token disable" disables
+the NFC password token.
+
+The NFC password token that is either pre-configured in the
+configuration file (wps_nfc_dev_pw_id, wps_nfc_dh_pubkey,
+wps_nfc_dh_privkey, wps_nfc_dev_pw) or generated dynamically with
+"wps_nfc_token <WPS|NDEF>" command. The nfc_pw_token tool from
+wpa_supplicant can be used to generate NFC password tokens during
+manufacturing (each AP needs to have its own random keys).
+
+The "wps_nfc_config_token <WPS/NDEF>" command can be used to build an
+NFC configuration token. The output value from this command is a hexdump
+of the current AP configuration (WPS parameter requests this to include
+only the WPS attributes; NDEF parameter requests additional NDEF
+encapsulation to be included). This data needs to be written to an NFC
+tag with an external program. Once written, the NFC configuration token
+can be used to touch an NFC interface on a station to provision the
+credentials needed to access the network.
+
+When the NFC device on the AP reads an NFC tag with a MIME media type
+"application/vnd.wfa.wsc", the NDEF message payload (with or without
+NDEF encapsulation) can be delivered to hostapd using the
+following hostapd_cli command:
+
+wps_nfc_tag_read <hexdump of payload>
+
+If the NFC tag contains a password token, the token is added to the
+internal Registrar. This allows station Enrollee from which the password
+token was received to run through WPS protocol to provision the
+credential.

+# hostapd depends on strong random number generation being available from the
+# operating system. os_get_random() function is used to fetch random data when
+# needed, e.g., for key generation. On Linux and BSD systems, this works by
+# reading /dev/urandom. It should be noted that the OS entropy pool needs to be
+# properly initialized before hostapd is started. This is important especially
+# on embedded devices that do not have a hardware random number generator and
+# may by default start up with minimal entropy available for random number
+# generation.
+#
+# As a safety net, hostapd is by default trying to internally collect
+# additional entropy for generating random data to mix in with the data
+# fetched from the OS. This by itself is not considered to be very strong, but
+# it may help in cases where the system pool is not initialized properly.
+# However, it is very strongly recommended that the system pool is initialized
+# with enough entropy either by using hardware assisted random number
+# generator or by storing state over device reboots.
+#
+# hostapd can be configured to maintain its own entropy store over restarts to
+# enhance random number generation. This is not perfect, but it is much more
+# secure than using the same sequence of random numbers after every reboot.
+# This can be enabled with -e<entropy file> command line option. The specified
+# file needs to be readable and writable by hostapd.
+#
+# If the os_get_random() is known to provide strong random data (e.g., on
+# Linux/BSD, the board in question is known to have reliable source of random
+# data from /dev/urandom), the internal hostapd random pool can be disabled.

+ *
+ * This is an example implementation of the EAP-SIM/AKA database/authentication
+ * gateway interface to HLR/AuC. It is expected to be replaced with an
+ * implementation of SS7 gateway to GSM/UMTS authentication center (HLR/AuC) or
+ * a local implementation of SIM triplet and AKA authentication data generator.
+ *
+ * hostapd will send SIM/AKA authentication queries over a UNIX domain socket
+ * to and external program, e.g., this hlr_auc_gw. This interface uses simple
+ * text-based format:
+ *
+ * EAP-SIM / GSM triplet query/response:
+ * SIM-REQ-AUTH <IMSI> <max_chal>
+ * SIM-RESP-AUTH <IMSI> Kc1:SRES1:RAND1 Kc2:SRES2:RAND2 [Kc3:SRES3:RAND3]
+ * SIM-RESP-AUTH <IMSI> FAILURE
+ *
+ * EAP-AKA / UMTS query/response:
+ * AKA-REQ-AUTH <IMSI>
+ * AKA-RESP-AUTH <IMSI> <RAND> <AUTN> <IK> <CK> <RES>
+ * AKA-RESP-AUTH <IMSI> FAILURE
+ *
+ * EAP-AKA / UMTS AUTS (re-synchronization):
+ * AKA-AUTS <IMSI> <AUTS> <RAND>
+ *
+ * IMSI and max_chal are sent as an ASCII string,
+ * Kc/SRES/RAND/AUTN/IK/CK/RES/AUTS as hex strings.
+ *
+ * The example implementation here reads GSM authentication triplets from a
+ * text file in IMSI:Kc:SRES:RAND format, IMSI in ASCII, other fields as hex
+ * strings. This is used to simulate an HLR/AuC. As such, it is not very useful
+ * for real life authentication, but it is useful both as an example
+ * implementation and for EAP-SIM/AKA/AKA' testing.
+ *
+ * SQN generation follows the not time-based Profile 2 described in
+ * 3GPP TS 33.102 Annex C.3.2. The length of IND is 5 bits by default, but this
+ * can be changed with a command line options if needed.

+HLR/AuC testing gateway for hostapd EAP-SIM/AKA database/authenticator
+
+hlr_auc_gw is an example implementation of the EAP-SIM/AKA/AKA'
+database/authentication gateway interface to HLR/AuC. It could be
+replaced with an implementation of SS7 gateway to GSM/UMTS
+authentication center (HLR/AuC). hostapd will send SIM/AKA
+authentication queries over a UNIX domain socket to and external
+program, e.g., hlr_auc_gw.
+
+hlr_auc_gw can be configured with GSM and UMTS authentication data with
+text files: GSM triplet file (see hostapd.sim_db) and Milenage file (see
+hlr_auc_gw.milenage_db). Milenage parameters can be used to generate
+dynamic authentication data for EAP-SIM, EAP-AKA, and EAP-AKA' while the
+GSM triplet data is used for a more static configuration (e.g., triplets
+extracted from a SIM card).
+
+Alternatively, hlr_auc_gw can be built with support for an SQLite
+database for more dynamic operations. This is enabled by adding
+"CONFIG_SQLITE=y" into hostapd/.config before building hlr_auc_gw ("make
+clean; make hlr_auc_gw" in this directory).
+
+hostapd is configured to use hlr_auc_gw with the eap_sim_db parameter in
+hostapd.conf (e.g., "eap_sim_db=unix:/tmp/hlr_auc_gw.sock"). hlr_auc_gw
+is configured with command line parameters:
+
+hlr_auc_gw [-hu] [-s<socket path>] [-g<triplet file>] [-m<milenage file>] \
+        [-D<DB file>] [-i<IND len in bits>]
+
+options:
+  -h = show this usage help
+  -u = update SQN in Milenage file on exit
+  -s<socket path> = path for UNIX domain socket
+                    (default: /tmp/hlr_auc_gw.sock)
+  -g<triplet file> = path for GSM authentication triplets
+  -m<milenage file> = path for Milenage keys
+  -D<DB file> = path to SQLite database
+  -i<IND len in bits> = IND length for SQN (default: 5)
+
+
+The SQLite database can be initialized with sqlite, e.g., by running
+following commands in "sqlite3 /path/to/hlr_auc_gw.db":
+
+CREATE TABLE milenage(
+	imsi INTEGER PRIMARY KEY NOT NULL,
+	ki CHAR(32) NOT NULL,
+	opc CHAR(32) NOT NULL,
+	amf CHAR(4) NOT NULL,
+	sqn CHAR(12) NOT NULL
+);
+INSERT INTO milenage(imsi,ki,opc,amf,sqn) VALUES(
+	232010000000000,
+	'90dca4eda45b53cf0f12d7c9c3bc6a89',
+	'cb9cccc4b9258e6dca4760379fb82581',
+	'61df',
+	'000000000000'
+);
+INSERT INTO milenage(imsi,ki,opc,amf,sqn) VALUES(
+	555444333222111,
+	'5122250214c33e723a5dd523fc145fc0',
+	'981d464c7c52eb6e5036234984ad0bcf',
+	'c3ab',
+	'16f3b3f70fc1'
+);
+
+
+hostapd (EAP server) can also be configured to store the EAP-SIM/AKA
+pseudonyms and reauth information into a SQLite database. This is
+configured with the db parameter within the eap_sim_db configuration
+option.
+
+
+"hlr_auc_gw -D /path/to/hlr_auc_gw.db" can then be used to fetch
+Milenage parameters based on IMSI from the database. The database can be
+updated dynamically while hlr_auc_gw is running to add/remove/modify
+entries.
+
+
+Example configuration files for hostapd to operate as a RADIUS
+authentication server for EAP-SIM/AKA/AKA':
+
+hostapd.conf:

+##### Multiple BSSID support ##################################################
+#
+# Above configuration is using the default interface (wlan#, or multi-SSID VLAN
+# interfaces). Other BSSIDs can be added by using separator 'bss' with
+# default interface name to be allocated for the data packets of the new BSS.
+#
+# hostapd will generate BSSID mask based on the BSSIDs that are
+# configured. hostapd will verify that dev_addr & MASK == dev_addr. If this is
+# not the case, the MAC address of the radio must be changed before starting
+# hostapd (ifconfig wlan0 hw ether <MAC addr>). If a BSSID is configured for
+# every secondary BSS, this limitation is not applied at hostapd and other
+# masks may be used if the driver supports them (e.g., swap the locally
+# administered bit)
+#
+# BSSIDs are assigned in order to each BSS, unless an explicit BSSID is
+# specified using the 'bssid' parameter.
+# If an explicit BSSID is specified, it must be chosen such that it:
+# - results in a valid MASK that covers it and the dev_addr
+# - is not the same as the MAC address of the radio
+# - is not the same as any other explicitly specified BSSID
+#
+# Please note that hostapd uses some of the values configured for the first BSS
+# as the defaults for the following BSSes. However, it is recommended that all
+# BSSes include explicit configuration of all relevant configuration items.
+#

+# Each line must contain an identity, EAP method(s), and an optional password

+# double quoted ("user"). Password can alternatively be stored as
+# NtPasswordHash (16-byte MD4 hash of the unicode presentation of the password
+# in unicode) if it is used for MSCHAP or MSCHAPv2 authentication. This means
+# that the plaintext password does not need to be included in the user file.
+# Password hash is stored as hash:<16-octets of hex data> without quotation
+# marks.
+
+# [2] flag in the end of the line can be used to mark users for tunneled phase
+# 2 authentication (e.g., within EAP-PEAP). In these cases, an anonymous
+# identity can be used in the unencrypted phase 1 and the real user identity
+# is transmitted only within the encrypted tunnel in phase 2. If non-anonymous
+# access is needed, two user entries is needed, one for phase 1 and another
+# with the same username for phase 2.
+#
+# EAP-TLS, EAP-PEAP, EAP-TTLS, EAP-FAST, EAP-SIM, and EAP-AKA do not use

+#
+# * can be used as a wildcard to match any user identity. The main purposes for

+# avoid having to configure every certificate for EAP-TLS authentication. The
+# first matching entry is selected, so * should be used as the last phase 1
+# user entry.
+#
+# "prefix"* can be used to match the given prefix and anything after this. The
+# main purpose for this is to be able to avoid EAP method negotiation when the
+# method is using known prefix in identities (e.g., EAP-SIM and EAP-AKA). This
+# is only allowed for phase 1 identities.
+#
+# Multiple methods can be configured to make the authenticator try them one by
+# one until the peer accepts one. The method names are separated with a
+# comma (,).
+#
+# [ver=0] and [ver=1] flags after EAP type PEAP can be used to force PEAP

+This patch adds support for TLS SessionTicket extension (RFC 5077) for
+the parts used by EAP-FAST (RFC 4851).
+
+This is based on the patch from Alexey Kobozev <akobozev@cisco.com>
+(sent to openssl-dev mailing list on Tue, 07 Jun 2005 15:40:58 +0300).
+
+OpenSSL 0.9.8i does not enable TLS extension support by default, so it
+will need to be enabled by adding enable-tlsext to config script
+command line.

+This patch adds support for TLS SessionTicket extension (RFC 5077) for
+the parts used by EAP-FAST (RFC 4851).
+
+This is based on the patch from Alexey Kobozev <akobozev@cisco.com>
+(sent to openssl-dev mailing list on Tue, 07 Jun 2005 15:40:58 +0300).
+
+OpenSSL 0.9.8x does not enable TLS extension support by default, so it
+will need to be enabled by adding enable-tlsext to config script
+command line.

+This patch adds support for TLS SessionTicket extension (RFC 5077) for
+the parts used by EAP-FAST (RFC 4851).
+
+This is based on the patch from Alexey Kobozev <akobozev@cisco.com>
+(sent to openssl-dev mailing list on Tue, 07 Jun 2005 15:40:58 +0300).
+
+NOTE: This patch (without SSL_set_hello_extension() wrapper) was
+merged into the upstream OpenSSL 0.9.9 tree and as such, an external
+patch for EAP-FAST support is not needed anymore.

+Example application using RADIUS client as a library
+Copyright (c) 2007, Jouni Malinen <j@w1.fi>
+
+This software may be distributed under the terms of the BSD license.
+See the parent directory README for more details.
+
+
+This directory contains an example showing how the RADIUS client
+functionality from hostapd can be used as a library in another
+program. The example program initializes the RADIUS client and send a
+Access-Request using User-Name and User-Password attributes. A reply
+from the RADIUS authentication server will be processed and it is used
+as a trigger to terminate the example program.
+
+The RADIUS library links in couple of helper functions from src/utils and
+src/crypto directories. Most of these are suitable as-is, but it may
+be desirable to replace the debug output code in src/utils/wpa_debug.c
+by dropping this file from the library and re-implementing the
+functions there in a way that better fits in with the main
+application.
+
+RADIUS client implementation takes care of receiving messages,
+timeouts, and retransmissions of packets. Consequently, it requires
+functionality for registering timeouts and received packet
+notifications. This is implemented using the generic event loop
+implementation (see src/utils/eloop.h).
+
+The main application may either use the included event loop
+implementation or alternatively, implement eloop_* wrapper functions
+to use whatever event loop design is used in the main program. This
+would involve removing src/utils/eloop.o from the library and
+implementing following functions defines in src/utils/eloop.h:
+eloop_register_timeout(), eloop_cancel_timeout(),
+eloop_register_read_sock(), eloop_unregister_read_sock(), and
+eloop_terminated().

+SHA-1 in C
+By Steve Reid <sreid@sea-to-sky.net>
+100% Public Domain
+
+-----------------
+Modified 7/98 
+By James H. Brown <jbrown@burgoyne.com>
+Still 100% Public Domain
+
+Corrected a problem which generated improper hash values on 16 bit machines
+Routine SHA1Update changed from
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned int
+len)
+to
+	void SHA1Update(SHA1_CTX* context, unsigned char* data, unsigned
+long len)
+
+The 'len' parameter was declared an int which works fine on 32 bit machines.
+However, on 16 bit machines an int is too small for the shifts being done
+against
+it.  This caused the hash function to generate incorrect values if len was
+greater than 8191 (8K - 1) due to the 'len << 3' on line 3 of SHA1Update().
+
+Since the file IO in main() reads 16K at a time, any file 8K or larger would
+be guaranteed to generate the wrong hash (e.g. Test Vector #3, a million
+"a"s).
+
+I also changed the declaration of variables i & j in SHA1Update to 
+unsigned long from unsigned int for the same reason.
+
+These changes should make no difference to any 32 bit implementations since
+an
+int and a long are the same size in those environments.
+
+--
+I also corrected a few compiler warnings generated by Borland C.
+1. Added #include <process.h> for exit() prototype
+2. Removed unused variable 'j' in SHA1Final
+3. Changed exit(0) to return(0) at end of main.
+
+ALL changes I made can be located by searching for comments containing 'JHB'
+-----------------
+Modified 8/98
+By Steve Reid <sreid@sea-to-sky.net>
+Still 100% public domain
+
+1- Removed #include <process.h> and used return() instead of exit()
+2- Fixed overwriting of finalcount in SHA1Final() (discovered by Chris Hall)
+3- Changed email address from steve@edmweb.com to sreid@sea-to-sky.net
+
+-----------------
+Modified 4/01

+/**
+ * DOC: Frame transmission/registration support

+ * Frame transmission and registration support exists to allow userspace

+ * that are not being handled by the kernel. This includes, for example,
+ * certain classes of action frames that cannot be handled in the kernel
+ * for various reasons.
+ *
+ * Frame registration is done on a per-interface basis and registrations
+ * cannot be removed other than by closing the socket. It is possible to
+ * specify a registration filter to register, for example, only for a
+ * certain type of action frame. In particular with action frames, those
+ * that userspace registers for will not be returned as unhandled by the
+ * driver, so that the registered application has to take responsibility
+ * for doing that.
+ *
+ * The type of frame that can be registered for is also dependent on the
+ * driver and interface type. The frame types are advertised in wiphy
+ * attributes so applications know what to expect.
+ *
+ * NOTE: When an interface changes type while registrations are active,
+ *       these registrations are ignored until the interface type is
+ *       changed again. This means that changing the interface type can
+ *       lead to a situation that couldn't otherwise be produced, but
+ *       any such registrations will be dormant in the sense that they
+ *       will not be serviced, i.e. they will not receive any frames.
+ *
+ * Frame transmission allows userspace to send for example the required
+ * responses to action frames. It is subject to some sanity checking,
+ * but many frames can be transmitted. When a frame was transmitted, its
+ * status is indicated to the sending socket.
+ *
+ * For more technical details, see the corresponding command descriptions
+ * below.

+/**
+ * DOC: Virtual interface / concurrency capabilities
+ *
+ * Some devices are able to operate with virtual MACs, they can have
+ * more than one virtual interface. The capability handling for this
+ * is a bit complex though, as there may be a number of restrictions
+ * on the types of concurrency that are supported.
+ *
+ * To start with, each device supports the interface types listed in
+ * the %NL80211_ATTR_SUPPORTED_IFTYPES attribute, but by listing the
+ * types there no concurrency is implied.
+ *
+ * Once concurrency is desired, more attributes must be observed:
+ * To start with, since some interface types are purely managed in
+ * software, like the AP-VLAN type in mac80211 for example, there's
+ * an additional list of these, they can be added at any time and
+ * are only restricted by some semantic restrictions (e.g. AP-VLAN
+ * cannot be added without a corresponding AP interface). This list
+ * is exported in the %NL80211_ATTR_SOFTWARE_IFTYPES attribute.
+ *
+ * Further, the list of supported combinations is exported. This is
+ * in the %NL80211_ATTR_INTERFACE_COMBINATIONS attribute. Basically,
+ * it exports a list of "groups", and at any point in time the
+ * interfaces that are currently active must fall into any one of
+ * the advertised groups. Within each group, there are restrictions
+ * on the number of interfaces of different types that are supported
+ * and also the number of different channels, along with potentially
+ * some other restrictions. See &enum nl80211_if_combination_attrs.
+ *
+ * All together, these attributes define the concurrency of virtual
+ * interfaces that a given device supports.

+ * @NL80211_CMD_SET_REG: Set current regulatory domain. CRDA sends this command
+ *	after being queried by the kernel. CRDA replies by sending a regulatory

+ *	current alpha2 if it found a match. It also provides
+ * 	NL80211_ATTR_REG_RULE_FLAGS, and a set of regulatory rules. Each

+ * 	%NL80211_ATTR_REG_RULE_POWER_MAX_ANT_GAIN and
+ * 	%NL80211_ATTR_REG_RULE_POWER_MAX_EIRP.
+ * @NL80211_CMD_REQ_SET_REG: ask the wireless core to set the regulatory domain
+ * 	to the specified ISO/IEC 3166-1 alpha2 country code. The core will
+ * 	store this as a valid request and then query userspace for it.
+ *
+ * @NL80211_CMD_GET_MESH_CONFIG: Get mesh networking properties for the

+ *
+ * @NL80211_CMD_SET_MESH_CONFIG: Set mesh networking properties for the
+ *      interface identified by %NL80211_ATTR_IFINDEX
+ *
+ * @NL80211_CMD_SET_MGMT_EXTRA_IE: Set extra IEs for management frames. The
+ *	interface is identified with %NL80211_ATTR_IFINDEX and the management
+ *	frame subtype with %NL80211_ATTR_MGMT_SUBTYPE. The extra IE data to be
+ *	added to the end of the specified management frame is specified with
+ *	%NL80211_ATTR_IE. If the command succeeds, the requested data will be
+ *	added to all specified management frames generated by
+ *	kernel/firmware/driver.
+ *	Note: This command has been removed and it is only reserved at this
+ *	point to avoid re-using existing command number. The functionality this
+ *	command was planned for has been provided with cleaner design with the
+ *	option to specify additional IEs in NL80211_CMD_TRIGGER_SCAN,
+ *	NL80211_CMD_AUTHENTICATE, NL80211_CMD_ASSOCIATE,
+ *	NL80211_CMD_DEAUTHENTICATE, and NL80211_CMD_DISASSOCIATE.
+ *
+ * @NL80211_CMD_GET_SCAN: get scan results
+ * @NL80211_CMD_TRIGGER_SCAN: trigger a new scan with the given parameters
+ *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
+ *	probe requests at CCK rate or not.
+ * @NL80211_CMD_NEW_SCAN_RESULTS: scan notification (as a reply to
+ *	NL80211_CMD_GET_SCAN and on the "scan" multicast group)
+ * @NL80211_CMD_SCAN_ABORTED: scan was aborted, for unspecified reasons,
+ *	partial scan results may be available
+ *
+ * @NL80211_CMD_START_SCHED_SCAN: start a scheduled scan at certain
+ *	intervals, as specified by %NL80211_ATTR_SCHED_SCAN_INTERVAL.
+ *	Like with normal scans, if SSIDs (%NL80211_ATTR_SCAN_SSIDS)
+ *	are passed, they are used in the probe requests.  For
+ *	broadcast, a broadcast SSID must be passed (ie. an empty
+ *	string).  If no SSID is passed, no probe requests are sent and
+ *	a passive scan is performed.  %NL80211_ATTR_SCAN_FREQUENCIES,
+ *	if passed, define which channels should be scanned; if not
+ *	passed, all channels allowed for the current regulatory domain
+ *	are used.  Extra IEs can also be passed from the userspace by
+ *	using the %NL80211_ATTR_IE attribute.
+ * @NL80211_CMD_STOP_SCHED_SCAN: stop a scheduled scan.  Returns -ENOENT
+ *	if scheduled scan is not running.
+ * @NL80211_CMD_SCHED_SCAN_RESULTS: indicates that there are scheduled scan
+ *	results available.
+ * @NL80211_CMD_SCHED_SCAN_STOPPED: indicates that the scheduled scan has
+ *	stopped.  The driver may issue this event at any time during a
+ *	scheduled scan.  One reason for stopping the scan is if the hardware
+ *	does not support starting an association or a normal scan while running
+ *	a scheduled scan.  This event is also sent when the
+ *	%NL80211_CMD_STOP_SCHED_SCAN command is received or when the interface
+ *	is brought down while a scheduled scan was running.
+ *
+ * @NL80211_CMD_GET_SURVEY: get survey resuls, e.g. channel occupation
+ *      or noise level
+ * @NL80211_CMD_NEW_SURVEY_RESULTS: survey data notification (as a reply to
+ *	NL80211_CMD_GET_SURVEY and on the "scan" multicast group)
+ *
+ * @NL80211_CMD_SET_PMKSA: Add a PMKSA cache entry, using %NL80211_ATTR_MAC
+ *	(for the BSSID) and %NL80211_ATTR_PMKID.
+ * @NL80211_CMD_DEL_PMKSA: Delete a PMKSA cache entry, using %NL80211_ATTR_MAC
+ *	(for the BSSID) and %NL80211_ATTR_PMKID.
+ * @NL80211_CMD_FLUSH_PMKSA: Flush all PMKSA cache entries.
+ *
+ * @NL80211_CMD_REG_CHANGE: indicates to userspace the regulatory domain
+ * 	has been changed and provides details of the request information
+ * 	that caused the change such as who initiated the regulatory request
+ * 	(%NL80211_ATTR_REG_INITIATOR), the wiphy_idx
+ * 	(%NL80211_ATTR_REG_ALPHA2) on which the request was made from if
+ * 	the initiator was %NL80211_REGDOM_SET_BY_COUNTRY_IE or
+ * 	%NL80211_REGDOM_SET_BY_DRIVER, the type of regulatory domain
+ * 	set (%NL80211_ATTR_REG_TYPE), if the type of regulatory domain is
+ * 	%NL80211_REG_TYPE_COUNTRY the alpha2 to which we have moved on
+ * 	to (%NL80211_ATTR_REG_ALPHA2).
+ * @NL80211_CMD_REG_BEACON_HINT: indicates to userspace that an AP beacon
+ * 	has been found while world roaming thus enabling active scan or
+ * 	any mode of operation that initiates TX (beacons) on a channel
+ * 	where we would not have been able to do either before. As an example
+ * 	if you are world roaming (regulatory domain set to world or if your
+ * 	driver is using a custom world roaming regulatory domain) and while
+ * 	doing a passive scan on the 5 GHz band you find an AP there (if not
+ * 	on a DFS channel) you will now be able to actively scan for that AP
+ * 	or use AP mode on your card on that same channel. Note that this will
+ * 	never be used for channels 1-11 on the 2 GHz band as they are always
+ * 	enabled world wide. This beacon hint is only sent if your device had
+ * 	either disabled active scanning or beaconing on a channel. We send to
+ * 	userspace the wiphy on which we removed a restriction from
+ * 	(%NL80211_ATTR_WIPHY) and the channel on which this occurred
+ * 	before (%NL80211_ATTR_FREQ_BEFORE) and after (%NL80211_ATTR_FREQ_AFTER)
+ * 	the beacon hint was processed.
+ *
+ * @NL80211_CMD_AUTHENTICATE: authentication request and notification.
+ *	This command is used both as a command (request to authenticate) and
+ *	as an event on the "mlme" multicast group indicating completion of the
+ *	authentication process.
+ *	When used as a command, %NL80211_ATTR_IFINDEX is used to identify the
+ *	interface. %NL80211_ATTR_MAC is used to specify PeerSTAAddress (and
+ *	BSSID in case of station mode). %NL80211_ATTR_SSID is used to specify
+ *	the SSID (mainly for association, but is included in authentication
+ *	request, too, to help BSS selection. %NL80211_ATTR_WIPHY_FREQ is used
+ *	to specify the frequence of the channel in MHz. %NL80211_ATTR_AUTH_TYPE
+ *	is used to specify the authentication type. %NL80211_ATTR_IE is used to
+ *	define IEs (VendorSpecificInfo, but also including RSN IE and FT IEs)
+ *	to be added to the frame.
+ *	When used as an event, this reports reception of an Authentication
+ *	frame in station and IBSS modes when the local MLME processed the
+ *	frame, i.e., it was for the local STA and was received in correct
+ *	state. This is similar to MLME-AUTHENTICATE.confirm primitive in the
+ *	MLME SAP interface (kernel providing MLME, userspace SME). The
+ *	included %NL80211_ATTR_FRAME attribute contains the management frame
+ *	(including both the header and frame body, but not FCS). This event is
+ *	also used to indicate if the authentication attempt timed out. In that
+ *	case the %NL80211_ATTR_FRAME attribute is replaced with a
+ *	%NL80211_ATTR_TIMED_OUT flag (and %NL80211_ATTR_MAC to indicate which
+ *	pending authentication timed out).
+ * @NL80211_CMD_ASSOCIATE: association request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Association and Reassociation
+ *	(similar to MLME-ASSOCIATE.request, MLME-REASSOCIATE.request,
+ *	MLME-ASSOCIATE.confirm or MLME-REASSOCIATE.confirm primitives).
+ * @NL80211_CMD_DEAUTHENTICATE: deauthentication request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Deauthentication frames (similar to
+ *	MLME-DEAUTHENTICATION.request and MLME-DEAUTHENTICATE.indication
+ *	primitives).
+ * @NL80211_CMD_DISASSOCIATE: disassociation request and notification; like
+ *	NL80211_CMD_AUTHENTICATE but for Disassociation frames (similar to
+ *	MLME-DISASSOCIATE.request and MLME-DISASSOCIATE.indication primitives).
+ *
+ * @NL80211_CMD_MICHAEL_MIC_FAILURE: notification of a locally detected Michael
+ *	MIC (part of TKIP) failure; sent on the "mlme" multicast group; the
+ *	event includes %NL80211_ATTR_MAC to describe the source MAC address of
+ *	the frame with invalid MIC, %NL80211_ATTR_KEY_TYPE to show the key
+ *	type, %NL80211_ATTR_KEY_IDX to indicate the key identifier, and
+ *	%NL80211_ATTR_KEY_SEQ to indicate the TSC value of the frame; this
+ *	event matches with MLME-MICHAELMICFAILURE.indication() primitive
+ *
+ * @NL80211_CMD_JOIN_IBSS: Join a new IBSS -- given at least an SSID and a
+ *	FREQ attribute (for the initial frequency if no peer can be found)
+ *	and optionally a MAC (as BSSID) and FREQ_FIXED attribute if those
+ *	should be fixed rather than automatically determined. Can only be
+ *	executed on a network interface that is UP, and fixed BSSID/FREQ
+ *	may be rejected. Another optional parameter is the beacon interval,
+ *	given in the %NL80211_ATTR_BEACON_INTERVAL attribute, which if not
+ *	given defaults to 100 TU (102.4ms).
+ * @NL80211_CMD_LEAVE_IBSS: Leave the IBSS -- no special arguments, the IBSS is
+ *	determined by the network interface.
+ *
+ * @NL80211_CMD_TESTMODE: testmode command, takes a wiphy (or ifindex) attribute
+ *	to identify the device, and the TESTDATA blob attribute to pass through
+ *	to the driver.
+ *
+ * @NL80211_CMD_CONNECT: connection request and notification; this command
+ *	requests to connect to a specified network but without separating
+ *	auth and assoc steps. For this, you need to specify the SSID in a
+ *	%NL80211_ATTR_SSID attribute, and can optionally specify the association
+ *	IEs in %NL80211_ATTR_IE, %NL80211_ATTR_AUTH_TYPE, %NL80211_ATTR_MAC,
+ *	%NL80211_ATTR_WIPHY_FREQ, %NL80211_ATTR_CONTROL_PORT,
+ *	%NL80211_ATTR_CONTROL_PORT_ETHERTYPE and
+ *	%NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT.
+ *	Background scan period can optionally be
+ *	specified in %NL80211_ATTR_BG_SCAN_PERIOD,
+ *	if not specified default background scan configuration
+ *	in driver is used and if period value is 0, bg scan will be disabled.
+ *	This attribute is ignored if driver does not support roam scan.
+ *	It is also sent as an event, with the BSSID and response IEs when the
+ *	connection is established or failed to be established. This can be
+ *	determined by the STATUS_CODE attribute.
+ * @NL80211_CMD_ROAM: request that the card roam (currently not implemented),
+ *	sent as an event when the card/driver roamed by itself.
+ * @NL80211_CMD_DISCONNECT: drop a given connection; also used to notify
+ *	userspace that a connection was dropped by the AP or due to other
+ *	reasons, for this the %NL80211_ATTR_DISCONNECTED_BY_AP and
+ *	%NL80211_ATTR_REASON_CODE attributes are used.
+ *
+ * @NL80211_CMD_SET_WIPHY_NETNS: Set a wiphy's netns. Note that all devices
+ *	associated with this wiphy must be down and will follow.
+ *
+ * @NL80211_CMD_REMAIN_ON_CHANNEL: Request to remain awake on the specified
+ *	channel for the specified amount of time. This can be used to do
+ *	off-channel operations like transmit a Public Action frame and wait for
+ *	a response while being associated to an AP on another channel.
+ *	%NL80211_ATTR_IFINDEX is used to specify which interface (and thus
+ *	radio) is used. %NL80211_ATTR_WIPHY_FREQ is used to specify the
+ *	frequency for the operation and %NL80211_ATTR_WIPHY_CHANNEL_TYPE may be
+ *	optionally used to specify additional channel parameters.
+ *	%NL80211_ATTR_DURATION is used to specify the duration in milliseconds
+ *	to remain on the channel. This command is also used as an event to
+ *	notify when the requested duration starts (it may take a while for the
+ *	driver to schedule this time due to other concurrent needs for the
+ *	radio).
+ *	When called, this operation returns a cookie (%NL80211_ATTR_COOKIE)
+ *	that will be included with any events pertaining to this request;
+ *	the cookie is also used to cancel the request.
+ * @NL80211_CMD_CANCEL_REMAIN_ON_CHANNEL: This command can be used to cancel a
+ *	pending remain-on-channel duration if the desired operation has been
+ *	completed prior to expiration of the originally requested duration.
+ *	%NL80211_ATTR_WIPHY or %NL80211_ATTR_IFINDEX is used to specify the
+ *	radio. The %NL80211_ATTR_COOKIE attribute must be given as well to
+ *	uniquely identify the request.
+ *	This command is also used as an event to notify when a requested
+ *	remain-on-channel duration has expired.
+ *
+ * @NL80211_CMD_SET_TX_BITRATE_MASK: Set the mask of rates to be used in TX
+ *	rate selection. %NL80211_ATTR_IFINDEX is used to specify the interface
+ *	and @NL80211_ATTR_TX_RATES the set of allowed rates.
+ *
+ * @NL80211_CMD_REGISTER_FRAME: Register for receiving certain mgmt frames
+ *	(via @NL80211_CMD_FRAME) for processing in userspace. This command
+ *	requires an interface index, a frame type attribute (optional for
+ *	backward compatibility reasons, if not given assumes action frames)
+ *	and a match attribute containing the first few bytes of the frame
+ *	that should match, e.g. a single byte for only a category match or
+ *	four bytes for vendor frames including the OUI. The registration
+ *	cannot be dropped, but is removed automatically when the netlink
+ *	socket is closed. Multiple registrations can be made.
+ * @NL80211_CMD_REGISTER_ACTION: Alias for @NL80211_CMD_REGISTER_FRAME for
+ *	backward compatibility
+ * @NL80211_CMD_FRAME: Management frame TX request and RX notification. This
+ *	command is used both as a request to transmit a management frame and
+ *	as an event indicating reception of a frame that was not processed in
+ *	kernel code, but is for us (i.e., which may need to be processed in a
+ *	user space application). %NL80211_ATTR_FRAME is used to specify the
+ *	frame contents (including header). %NL80211_ATTR_WIPHY_FREQ (and
+ *	optionally %NL80211_ATTR_WIPHY_CHANNEL_TYPE) is used to indicate on
+ *	which channel the frame is to be transmitted or was received. If this
+ *	channel is not the current channel (remain-on-channel or the
+ *	operational channel) the device will switch to the given channel and
+ *	transmit the frame, optionally waiting for a response for the time
+ *	specified using %NL80211_ATTR_DURATION. When called, this operation
+ *	returns a cookie (%NL80211_ATTR_COOKIE) that will be included with the
+ *	TX status event pertaining to the TX request.
+ *	%NL80211_ATTR_TX_NO_CCK_RATE is used to decide whether to send the
+ *	management frames at CCK rate or not in 2GHz band.
+ * @NL80211_CMD_FRAME_WAIT_CANCEL: When an off-channel TX was requested, this
+ *	command may be used with the corresponding cookie to cancel the wait
+ *	time if it is known that it is no longer necessary.
+ * @NL80211_CMD_ACTION: Alias for @NL80211_CMD_FRAME for backward compatibility.
+ * @NL80211_CMD_FRAME_TX_STATUS: Report TX status of a management frame
+ *	transmitted with %NL80211_CMD_FRAME. %NL80211_ATTR_COOKIE identifies
+ *	the TX command and %NL80211_ATTR_FRAME includes the contents of the
+ *	frame. %NL80211_ATTR_ACK flag is included if the recipient acknowledged
+ *	the frame.
+ * @NL80211_CMD_ACTION_TX_STATUS: Alias for @NL80211_CMD_FRAME_TX_STATUS for
+ *	backward compatibility.
+ *
+ * @NL80211_CMD_SET_POWER_SAVE: Set powersave, using %NL80211_ATTR_PS_STATE
+ * @NL80211_CMD_GET_POWER_SAVE: Get powersave status in %NL80211_ATTR_PS_STATE
+ *
+ * @NL80211_CMD_SET_CQM: Connection quality monitor configuration. This command
+ *	is used to configure connection quality monitoring notification trigger
+ *	levels.
+ * @NL80211_CMD_NOTIFY_CQM: Connection quality monitor notification. This
+ *	command is used as an event to indicate the that a trigger level was
+ *	reached.
+ * @NL80211_CMD_SET_CHANNEL: Set the channel (using %NL80211_ATTR_WIPHY_FREQ
+ *	and %NL80211_ATTR_WIPHY_CHANNEL_TYPE) the given interface (identifed
+ *	by %NL80211_ATTR_IFINDEX) shall operate on.
+ *	In case multiple channels are supported by the device, the mechanism
+ *	with which it switches channels is implementation-defined.
+ *	When a monitor interface is given, it can only switch channel while
+ *	no other interfaces are operating to avoid disturbing the operation
+ *	of any other interfaces, and other interfaces will again take
+ *	precedence when they are used.
+ *
+ * @NL80211_CMD_SET_WDS_PEER: Set the MAC address of the peer on a WDS interface.
+ *
+ * @NL80211_CMD_JOIN_MESH: Join a mesh. The mesh ID must be given, and initial
+ *	mesh config parameters may be given.
+ * @NL80211_CMD_LEAVE_MESH: Leave the mesh network -- no special arguments, the
+ *	network is determined by the network interface.
+ *
+ * @NL80211_CMD_UNPROT_DEAUTHENTICATE: Unprotected deauthentication frame
+ *	notification. This event is used to indicate that an unprotected
+ *	deauthentication frame was dropped when MFP is in use.
+ * @NL80211_CMD_UNPROT_DISASSOCIATE: Unprotected disassociation frame
+ *	notification. This event is used to indicate that an unprotected
+ *	disassociation frame was dropped when MFP is in use.
+ *
+ * @NL80211_CMD_NEW_PEER_CANDIDATE: Notification on the reception of a
+ *      beacon or probe response from a compatible mesh peer.  This is only
+ *      sent while no station information (sta_info) exists for the new peer
+ *      candidate and when @NL80211_MESH_SETUP_USERSPACE_AUTH is set.  On
+ *      reception of this notification, userspace may decide to create a new
+ *      station (@NL80211_CMD_NEW_STATION).  To stop this notification from
+ *      reoccurring, the userspace authentication daemon may want to create the
+ *      new station with the AUTHENTICATED flag unset and maybe change it later
+ *      depending on the authentication result.
+ *
+ * @NL80211_CMD_GET_WOWLAN: get Wake-on-Wireless-LAN (WoWLAN) settings.
+ * @NL80211_CMD_SET_WOWLAN: set Wake-on-Wireless-LAN (WoWLAN) settings.
+ *	Since wireless is more complex than wired ethernet, it supports
+ *	various triggers. These triggers can be configured through this
+ *	command with the %NL80211_ATTR_WOWLAN_TRIGGERS attribute. For
+ *	more background information, see
+ *	http://wireless.kernel.org/en/users/Documentation/WoWLAN.
+ *
+ * @NL80211_CMD_SET_REKEY_OFFLOAD: This command is used give the driver
+ *	the necessary information for supporting GTK rekey offload. This
+ *	feature is typically used during WoWLAN. The configuration data
+ *	is contained in %NL80211_ATTR_REKEY_DATA (which is nested and
+ *	contains the data in sub-attributes). After rekeying happened,
+ *	this command may also be sent by the driver as an MLME event to
+ *	inform userspace of the new replay counter.
+ *
+ * @NL80211_CMD_PMKSA_CANDIDATE: This is used as an event to inform userspace
+ *	of PMKSA caching dandidates.
+ *
+ * @NL80211_CMD_TDLS_OPER: Perform a high-level TDLS command (e.g. link setup).
+ *	In addition, this can be used as an event to request userspace to take
+ *	actions on TDLS links (set up a new link or tear down an existing one).
+ *	In such events, %NL80211_ATTR_TDLS_OPERATION indicates the requested
+ *	operation, %NL80211_ATTR_MAC contains the peer MAC address, and
+ *	%NL80211_ATTR_REASON_CODE the reason code to be used (only with
+ *	%NL80211_TDLS_TEARDOWN).
+ * @NL80211_CMD_TDLS_MGMT: Send a TDLS management frame.
+ *
+ * @NL80211_CMD_UNEXPECTED_FRAME: Used by an application controlling an AP
+ *	(or GO) interface (i.e. hostapd) to ask for unexpected frames to
+ *	implement sending deauth to stations that send unexpected class 3
+ *	frames. Also used as the event sent by the kernel when such a frame
+ *	is received.
+ *	For the event, the %NL80211_ATTR_MAC attribute carries the TA and
+ *	other attributes like the interface index are present.
+ *	If used as the command it must have an interface index and you can
+ *	only unsubscribe from the event by closing the socket. Subscription
+ *	is also for %NL80211_CMD_UNEXPECTED_4ADDR_FRAME events.
+ *
+ * @NL80211_CMD_UNEXPECTED_4ADDR_FRAME: Sent as an event indicating that the
+ *	associated station identified by %NL80211_ATTR_MAC sent a 4addr frame
+ *	and wasn't already in a 4-addr VLAN. The event will be sent similarly
+ *	to the %NL80211_CMD_UNEXPECTED_FRAME event, to the same listener.
+ *
+ * @NL80211_CMD_PROBE_CLIENT: Probe an associated station on an AP interface
+ *	by sending a null data frame to it and reporting when the frame is
+ *	acknowleged. This is used to allow timing out inactive clients. Uses
+ *	%NL80211_ATTR_IFINDEX and %NL80211_ATTR_MAC. The command returns a
+ *	direct reply with an %NL80211_ATTR_COOKIE that is later used to match
+ *	up the event with the request. The event includes the same data and
+ *	has %NL80211_ATTR_ACK set if the frame was ACKed.
+ *
+ * @NL80211_CMD_REGISTER_BEACONS: Register this socket to receive beacons from
+ *	other BSSes when any interfaces are in AP mode. This helps implement
+ *	OLBC handling in hostapd. Beacons are reported in %NL80211_CMD_FRAME
+ *	messages. Note that per PHY only one application may register.
+ *
+ * @NL80211_CMD_SET_NOACK_MAP: sets a bitmap for the individual TIDs whether
+ *      No Acknowledgement Policy should be applied.
+ *
+ * @NL80211_CMD_CH_SWITCH_NOTIFY: An AP or GO may decide to switch channels
+ *	independently of the userspace SME, send this event indicating
+ *	%NL80211_ATTR_IFINDEX is now on %NL80211_ATTR_WIPHY_FREQ with
+ *	%NL80211_ATTR_WIPHY_CHANNEL_TYPE.
+ *
+ * @NL80211_CMD_START_P2P_DEVICE: Start the given P2P Device, identified by
+ *	its %NL80211_ATTR_WDEV identifier. It must have been created with
+ *	%NL80211_CMD_NEW_INTERFACE previously. After it has been started, the
+ *	P2P Device can be used for P2P operations, e.g. remain-on-channel and
+ *	public action frame TX.
+ * @NL80211_CMD_STOP_P2P_DEVICE: Stop the given P2P Device, identified by
+ *	its %NL80211_ATTR_WDEV identifier.
+ *
+ * @NL80211_CMD_CONN_FAILED: connection request to an AP failed; used to
+ *	notify userspace that AP has rejected the connection request from a
+ *	station, due to particular reason. %NL80211_ATTR_CONN_FAILED_REASON
+ *	is used for this.
+ *
+ * @NL80211_CMD_SET_MCAST_RATE: Change the rate used to send multicast frames
+ *	for IBSS or MESH vif.
+
+ * @NL80211_CMD_SCAN_CANCEL: Stop currently running scan (both sw and hw).
+ *	This operation will eventually invoke %NL80211_CMD_SCAN_ABORTED
+ *	event, partial scan results will be available. Returns -ENOENT
+ *	if scan is not running.
+ *
+ * @NL80211_CMD_IM_SCAN_RESULT: Intermediate scan result notification event,
+ *	this event could be enabled with @NL80211_ATTR_IM_SCAN_RESULT
+ *	flag during @NL80211_CMD_TRIGGER_SCAN. This event contains
+ *	%NL80211_BSS_BSSID which is used to specify the BSSID of received
+ *	scan result and %NL80211_BSS_SIGNAL_MBM to indicate signal strength.
+ *	On reception of this notification, userspace may decide to stop earlier
+ *	currently running scan with (@NL80211_CMD_SCAN_CANCEL).
+ *
+ * @NL80211_CMD_ROAMING_SUPPORT: A notify event used to alert userspace
+ *      regarding changes in roaming support by the driver. If roaming is
+ *      disabled (marked by the presence of @NL80211_ATTR_ROAMING_DISABLED flag)
+ *      userspace should disable background scans and roaming attempts.
+ *
+ * @NL80211_CMD_AP_CH_SWITCH: Perform a channel switch in the driver (for
+ *	AP/GO).
+ *	%NL80211_ATTR_WIPHY_FREQ: new channel frequency.
+ *	%NL80211_ATTR_CH_SWITCH_BLOCK_TX: block tx on the current channel.
+ *	%NL80211_ATTR_CH_SWITCH_POST_BLOCK_TX: block tx on the target channel.
+ *	%NL80211_FREQ_ATTR_CH_SWITCH_COUNT: number of TBTT's until the channel
+ *	switch event.
+ *
+ * @NL80211_CMD_REQ_CH_SW: Request a channel switch from a GO/AP.
+ *
+ * @NL80211_CMD_MAX: highest used command number
+ * @__NL80211_CMD_AFTER_LAST: internal use

+ *
+ * @NL80211_ATTR_WIPHY_ANTENNA_RX: Bitmap of allowed antennas for receiving.
+ *	This can be used to mask out antennas which are not attached or should
+ *	not be used for receiving. If an antenna is not selected in this bitmap

+ *	nl80211 capability flag.
+ *
+ * @NL80211_ATTR_BSS_HT_OPMODE: HT operation mode (u16)
+ *
+ * @NL80211_ATTR_KEY_DEFAULT_TYPES: A nested attribute containing flags

+ *
+ * @NL80211_ATTR_SCHED_SCAN_MATCH: Nested attribute with one or more
+ *	sets of attributes to match during scheduled scans.  Only BSSs
+ *	that match any of the sets will be reported.  These are
+ *	pass-thru filter rules.
+ *	For a match to succeed, the BSS must match all attributes of a
+ *	set.  Since not every hardware supports matching all types of
+ *	attributes, there is no guarantee that the reported BSSs are
+ *	fully complying with the match sets and userspace needs to be
+ *	able to ignore them by itself.
+ *	Thus, the implementation is somewhat hardware-dependent, but
+ *	this is only an optimization and the userspace application
+ *	needs to handle all the non-filtered results anyway.
+ *	If the match attributes don't make sense when combined with
+ *	the values passed in @NL80211_ATTR_SCAN_SSIDS (eg. if an SSID
+ *	is included in the probe request, but the match attributes

+ *	driver (or firmware) replies to Probe Request frames.
+ * @NL80211_ATTR_IE_ASSOC_RESP: Information element(s) for (Re)Association
+ *	Response frames. This is used with %NL80211_CMD_NEW_BEACON and

+ *	(Re)Association Response frames when the driver (or firmware) replies to
+ *	(Re)Association Request frames.
+ *
+ * @NL80211_ATTR_STA_WME: Nested attribute containing the wme configuration
+ *	of the station, see &enum nl80211_sta_wme_attr.

+ *
+ * @NL80211_ATTR_TX_NO_CCK_RATE: Indicates whether to use CCK rate or not
+ *	for management frames transmission. In order to avoid p2p probe/action
+ *	frames are being transmitted at CCK rate in 2GHz band, the user space

+ *	used for asking the driver to perform a TDLS operation.
+ *
+ * @NL80211_ATTR_DEVICE_AP_SME: This u32 attribute may be listed for devices

+ * This l2_packet implementation is explicitly for WinPcap and Windows events.
+ * l2_packet_pcap.c has support for WinPcap, but it requires polling to receive
+ * frames which means relatively long latency for EAPOL RX processing. The
+ * implementation here uses a separate thread to allow WinPcap to be receiving
+ * all the time to reduce latency for EAPOL receiving from about 100 ms to 3 ms
+ * when comparing l2_packet_pcap.c to l2_packet_winpcap.c. Extra sleep of 50 ms
+ * is added in to receive thread whenever no EAPOL frames has been received for
+ * a while. Whenever an EAPOL handshake is expected, this sleep is removed.
+ *
+ * The RX thread receives a frame and signals main thread through Windows event
+ * about the availability of a new frame. Processing the received frame is
+ * synchronized with pair of Windows events so that no extra buffer or queuing
+ * mechanism is needed. This implementation requires Windows specific event
+ * loop implementation, i.e., eloop_win.c.
+ *
+ * WinPcap has pcap_getevent() that could, in theory at least, be used to
+ * implement this kind of waiting with a simpler single-thread design. However,
+ * that event handle is not really signaled immediately when receiving each
+ * frame, so it does not really work for this kind of use.

+ * ieee80211_radiotap_iterator_init - radiotap parser iterator initialization
+ * @iterator: radiotap_iterator to initialize
+ * @radiotap_header: radiotap header to parse
+ * @max_length: total length we can parse into (eg, whole packet length)
+ *
+ * Returns: 0 or a negative error code if there is a problem.
+ *
+ * This function initializes an opaque iterator struct which can then
+ * be passed to ieee80211_radiotap_iterator_next() to visit every radiotap
+ * argument which is present in the header.  It knows about extended
+ * present headers and handles them.
+ *
+ * How to use:
+ * call __ieee80211_radiotap_iterator_init() to init a semi-opaque iterator
+ * struct ieee80211_radiotap_iterator (no need to init the struct beforehand)
+ * checking for a good 0 return code.  Then loop calling
+ * __ieee80211_radiotap_iterator_next()... it returns either 0,
+ * -ENOENT if there are no more args to parse, or -EINVAL if there is a problem.
+ * The iterator's @this_arg member points to the start of the argument
+ * associated with the current argument index that is present, which can be
+ * found in the iterator's @this_arg_index member.  This arg index corresponds
+ * to the IEEE80211_RADIOTAP_... defines.
+ *
+ * Radiotap header length:
+ * You can find the CPU-endian total radiotap header length in
+ * iterator->max_length after executing ieee80211_radiotap_iterator_init()
+ * successfully.
+ *
+ * Alignment Gotcha:
+ * You must take care when dereferencing iterator.this_arg
+ * for multibyte types... the pointer is not aligned.  Use
+ * get_unaligned((type *)iterator.this_arg) to dereference
+ * iterator.this_arg for type "type" safely on all arches.
+ *
+ * Example code:
+ * See Documentation/networking/radiotap-headers.txt

+ * httpread - Manage reading file(s) from HTTP/TCP socket
+ * Author: Ted Merrill
+ * Copyright 2008 Atheros Communications
+ *
+ * This software may be distributed under the terms of the BSD license.
+ * See README for more details.
+ *
+ * The files are buffered via internal callbacks from eloop, then presented to
+ * an application callback routine when completely read into memory. May also
+ * be used if no file is expected but just to get the header, including HTTP
+ * replies (e.g. HTTP/1.1 200 OK etc.).
+ *
+ * This does not attempt to be an optimally efficient implementation, but does
+ * attempt to be of reasonably small size and memory consumption; assuming that
+ * only small files are to be read. A maximum file size is provided by
+ * application and enforced.
+ *
+ * It is assumed that the application does not expect any of the following:
+ * -- transfer encoding other than chunked
+ * -- trailer fields
+ * It is assumed that, even if the other side requested that the connection be
+ * kept open, that we will close it (thus HTTP messages sent by application
+ * should have the connection closed field); this is allowed by HTTP/1.1 and
+ * simplifies things for us.
+ *
+ * Other limitations:
+ * -- HTTP header may not exceed a hard-coded size.
+ *
+ * Notes:
+ * This code would be massively simpler without some of the new features of
+ * HTTP/1.1, especially chunked data.

+/*
+ * XML parsing and formatting
+ *
+ * XML is a markup language based on unicode; usually (and in our case,
+ * always!) based on utf-8. utf-8 uses a variable number of bytes per
+ * character. utf-8 has the advantage that all non-ASCII unicode characters are
+ * represented by sequences of non-ascii (high bit set) bytes, whereas ASCII
+ * characters are single ascii bytes, thus we can use typical text processing.
+ *
+ * (One other interesting thing about utf-8 is that it is possible to look at
+ * any random byte and determine if it is the first byte of a character as
+ * versus a continuation byte).
+ *
+ * The base syntax of XML uses a few ASCII punctionation characters; any
+ * characters that would appear in the payload data are rewritten using
+ * sequences, e.g., &amp; for ampersand(&) and &lt for left angle bracket (<).
+ * Five such escapes total (more can be defined but that does not apply to our
+ * case). Thus we can safely parse for angle brackets etc.
+ *
+ * XML describes tree structures of tagged data, with each element beginning
+ * with an opening tag <label> and ending with a closing tag </label> with
+ * matching label. (There is also a self-closing tag <label/> which is supposed
+ * to be equivalent to <label></label>, i.e., no payload, but we are unlikely
+ * to see it for our purpose).
+ *
+ * Actually the opening tags are a little more complicated because they can
+ * contain "attributes" after the label (delimited by ascii space or tab chars)
+ * of the form attribute_label="value" or attribute_label='value'; as it turns
+ * out we do not have to read any of these attributes, just ignore them.
+ *
+ * Labels are any sequence of chars other than space, tab, right angle bracket
+ * (and ?), but may have an inner structure of <namespace><colon><plain_label>.
+ * As it turns out, we can ignore the namespaces, in fact we can ignore the
+ * entire tree hierarchy, because the plain labels we are looking for will be
+ * unique (not in general, but for this application). We do however have to be
+ * careful to skip over the namespaces.
+ *
+ * In generating XML we have to be more careful, but that is easy because
+ * everything we do is pretty canned. The only real care to take is to escape
+ * any special chars in our payload.

+/*
+ * This has been greatly stripped down from the original file
+ * (upnp_wps_device.c) by Ted Merrill, Atheros Communications
+ * in order to eliminate use of the bulky libupnp library etc.
+ *
+ * History:
+ * upnp_wps_device.c is/was a shim layer between wps_opt_upnp.c and
+ * the libupnp library.
+ * The layering (by Sony) was well done; only a very minor modification
+ * to API of upnp_wps_device.c was required.
+ * libupnp was found to be undesirable because:
+ * -- It consumed too much code and data space
+ * -- It uses multiple threads, making debugging more difficult
+ *      and possibly reducing reliability.
+ * -- It uses static variables and only supports one instance.
+ * The shim and libupnp are here replaced by special code written
+ * specifically for the needs of hostapd.
+ * Various shortcuts can and are taken to keep the code size small.
+ * Generally, execution time is not as crucial.
+ *
+ * BUGS:
+ * -- UPnP requires that we be able to resolve domain names.
+ * While uncommon, if we have to do it then it will stall the entire
+ * hostapd program, which is bad.
+ * This is because we use the standard linux getaddrinfo() function
+ * which is syncronous.
+ * An asyncronous solution would be to use the free "ares" library.
+ * -- Does not have a robust output buffering scheme.  Uses a single
+ * fixed size output buffer per TCP/HTTP connection, with possible (although
+ * unlikely) possibility of overflow and likely excessive use of RAM.
+ * A better solution would be to write the HTTP output as a buffered stream,
+ * using chunking: (handle header specially, then) generate data with
+ * a printf-like function into a buffer, catching buffer full condition,
+ * then send it out surrounded by http chunking.
+ * -- There is some code that could be separated out into the common
+ * library to be shared with wpa_supplicant.
+ * -- Needs renaming with module prefix to avoid polluting the debugger
+ * namespace and causing possible collisions with other static fncs
+ * and structure declarations when using the debugger.
+ * -- The http error code generation is pretty bogus, hopefully no one cares.

+/*
+ * Overview of WPS over UPnP:
+ *
+ * UPnP is a protocol that allows devices to discover each other and control
+ * each other. In UPnP terminology, a device is either a "device" (a server
+ * that provides information about itself and allows itself to be controlled)
+ * or a "control point" (a client that controls "devices") or possibly both.
+ * This file implements a UPnP "device".
+ *
+ * For us, we use mostly basic UPnP discovery, but the control part of interest
+ * is WPS carried via UPnP messages. There is quite a bit of basic UPnP
+ * discovery to do before we can get to WPS, however.
+ *
+ * UPnP discovery begins with "devices" send out multicast UDP packets to a
+ * certain fixed multicast IP address and port, and "control points" sending
+ * out other such UDP packets.
+ *
+ * The packets sent by devices are NOTIFY packets (not to be confused with TCP
+ * NOTIFY packets that are used later) and those sent by control points are
+ * M-SEARCH packets. These packets contain a simple HTTP style header. The
+ * packets are sent redundantly to get around packet loss. Devices respond to
+ * M-SEARCH packets with HTTP-like UDP packets containing HTTP/1.1 200 OK
+ * messages, which give similar information as the UDP NOTIFY packets.
+ *
+ * The above UDP packets advertise the (arbitrary) TCP ports that the
+ * respective parties will listen to. The control point can then do a HTTP
+ * SUBSCRIBE (something like an HTTP PUT) after which the device can do a
+ * separate HTTP NOTIFY (also like an HTTP PUT) to do event messaging.
+ *
+ * The control point will also do HTTP GET of the "device file" listed in the
+ * original UDP information from the device (see UPNP_WPS_DEVICE_XML_FILE
+ * data), and based on this will do additional GETs... HTTP POSTs are done to
+ * cause an action.
+ *
+ * Beyond some basic information in HTTP headers, additional information is in
+ * the HTTP bodies, in a format set by the SOAP and XML standards, a markup
+ * language related to HTML used for web pages. This language is intended to
+ * provide the ultimate in self-documentation by providing a universal
+ * namespace based on pseudo-URLs called URIs. Note that although a URI looks
+ * like a URL (a web address), they are never accessed as such but are used
+ * only as identifiers.
+ *
+ * The POST of a GetDeviceInfo gets information similar to what might be
+ * obtained from a probe request or response on Wi-Fi. WPS messages M1-M8
+ * are passed via a POST of a PutMessage; the M1-M8 WPS messages are converted
+ * to a bin64 ascii representation for encapsulation. When proxying messages,
+ * WLANEvent and PutWLANResponse are used.
+ *
+ * This of course glosses over a lot of details.

+	* removed Qt3-based wpa_gui (obsoleted by wpa_qui-qt4)
+	* removed unmaintained driver wrappers broadcom, iphone, osx, ralink,
+	  hostap, madwifi (hostap and madwifi remain available for hostapd;
+	  their wpa_supplicant functionality is obsoleted by wext)
+	* improved debug logging (human readable event names, interface name
+	  included in more entries)
+	* changed AP mode behavior to enable WPS only for open and
+	  WPA/WPA2-Personal configuration
+	* improved P2P concurrency operations
+	  - better coordination of concurrent scan and P2P search operations

+	    if the driver cannot support both at the same time
+	  - allow driver to indicate channel changes
+	  - added optional delay=<search delay in milliseconds> parameter for
+	    p2p_find to avoid taking all radio resources
+	  - use 500 ms p2p_find search delay by default during concurrent
+	    operations
+	  - allow all channels in GO Negotiation if the driver supports
+	    multi-channel concurrency
+	* added number of small changes to make it easier for static analyzers
+	  to understand the implementation
+	* fixed number of small bugs (see git logs for more details)

+	  for WPS use cases in AP mode
+	* EAP-AKA: keep pseudonym identity across EAP exchanges to match EAP-SIM
+	  behavior
+	* improved reassociation behavior in cases where association is rejected
+	  or when an AP disconnects us to handle common load balancing
+	  mechanisms
+	  - try to avoid extra scans when the needed information is available
+	* added optional "join" argument for p2p_prov_disc ctrl_iface command
+	* added group ifname to P2P-PROV-DISC-* events
+	* added P2P Device Address to AP-STA-DISCONNECTED event and use

+	    issues with some USIM cards
+	  - try to read MNC length from SIM/USIM
+	  - build realm according to 3GPP TS 23.003 with identity from the SIM
+	  - allow T1 protocol to be enabled
+	* added more WPS and P2P information available through D-Bus

+	  breaks interoperability with older versions
+	* added support for WFA Hotspot 2.0
+	  - GAS/ANQP to fetch network information
+	  - credential configuration and automatic network selections based on
+	    credential match with ANQP information
+	* limited PMKSA cache entries to be used only with the network context

+	  compressed domain name format and support multiple Bonjour PTR matches
+	  for the same key
+	* use deauthentication instead of disassociation for all disconnection
+	  operations; this removes the now unused disassociate() wpa_driver_ops
+	  callback

+	  multiple PBKDF2 operations
+	* added okc=1 global configuration parameter to allow OKC to be enabled

+	  interop issues with deployed station implementations that do not
+	  remove active PBC indication from Probe Request frames properly
+	* added basic support for 60 GHz band
+	* extend EAPOL frames processing workaround for roaming cases
+	  (postpone processing of unexpected EAPOL frame until association
+	  event to handle reordered events)
+
+2012-05-10 - v1.0
+	* bsd: Add support for setting HT values in IFM_MMASK.
+	* Delay STA entry removal until Deauth/Disassoc TX status in AP mode.
+	  This allows the driver to use PS buffering of Deauthentication and
+	  Disassociation frames when the STA is in power save sleep. Only
+	  available with drivers that provide TX status events for Deauth/
+	  Disassoc frames (nl80211).
+	* Drop oldest unknown BSS table entries first. This makes it less
+	  likely to hit connection issues in environments with huge number
+	  of visible APs.
+	* Add systemd support.
+	* Add support for setting the syslog facility from the config file
+	  at build time.
+	* atheros: Add support for IEEE 802.11w configuration.
+	* AP mode: Allow enable HT20 if driver supports it, by setting the
+	  config parameter ieee80211n.
+	* Allow AP mode to disconnect STAs based on low ACK condition (when
+	  the data connection is not working properly, e.g., due to the STA
+	  going outside the range of the AP). Disabled by default, enable by
+	  config option disassoc_low_ack.
+	* nl80211:
+	  - Support GTK rekey offload.
+	  - Support PMKSA candidate events. This adds support for RSN
+	    pre-authentication with nl80211 interface and drivers that handle
+	    roaming internally.
+	* dbus:
+	  - Add a DBus signal for EAP SM requests, emitted on the Interface
+	    object.
+	  - Export max scan ssids supported by the driver as MaxScanSSID.
+	  - Add signal Certification for information about server certification.
+	  - Add BSSExpireAge and BSSExpireCount interface properties and
+	    support set/get, which allows for setting BSS cache expiration age
+	    and expiration scan count.
+	  - Add ConfigFile to AddInterface properties.
+	  - Add Interface.Country property and support to get/set the value.
+	  - Add DBus property CurrentAuthMode.
+	  - P2P DBus API added.
+	  - Emit property changed events (for property BSSs) when adding/
+	    removing BSSs.
+	  - Treat '' in SSIDs of Interface.Scan as a request for broadcast
+	    scan, instead of ignoring it.
+	  - Add DBus getter/setter for FastReauth.
+	  - Raise PropertiesChanged on org.freedesktop.DBus.Properties.
+	* wpa_cli:
+	  - Send AP-STA-DISCONNECTED event when an AP disconnects a station
+	    due to inactivity.
+	  - Make second argument to set command optional. This can be used to
+	    indicate a zero length value.
+	  - Add signal_poll command.
+	  - Add bss_expire_age and bss_expire_count commands to set/get BSS
+	    cache expiration age and expiration scan count.
+	  - Add ability to set scan interval (the time in seconds wpa_s waits
+	    before requesting a new scan after failing to find a suitable
+	    network in scan results) using scan_interval command.
+	  - Add event CTRL-EVENT-ASSOC-REJECT for association rejected.
+	  - Add command get version, that returns wpa_supplicant version string.
+	  - Add command sta_autoconnect for disabling automatic reconnection
+	    on receiving disconnection event.
+	  - Setting bssid parameter to an empty string "" or any can now be
+	    used to clear the bssid_set flag in a network block, i.e., to remove
+	    bssid filtering.
+	  - Add tdls_testing command to add a special testing feature for
+	    changing TDLS behavior. Build param CONFIG_TDLS_TESTING must be
+	    enabled as well.
+	  - For interworking, add wpa_cli commands interworking_select,
+	    interworking_connect, anqp_get, fetch_anqp, and stop_fetch_anqp.
+	  - Many P2P commands were added. See README-P2P.
+	  - Many WPS/WPS ER commands - see WPS/WPS ER sections for details.
+	  - Allow set command to change global config parameters.
+	  - Add log_level command, which can be used to display the current
+	    debugging level and to change the log level during run time.
+	  - Add note command, which can be used to insert notes to the debug
+	    log.
+	  - Add internal line edit implementation. CONFIG_WPA_CLI_EDIT=y
+	    can now be used to build wpa_cli with internal implementation of
+	    line editing and history support. This can be used as a replacement
+	    for CONFIG_READLINE=y.
+	* AP mode: Add max_num_sta config option, which can be used to limit
+	  the number of stations allowed to connect to the AP.
+	* Add WPA_IGNORE_CONFIG_ERRORS build option to continue in case of bad
+	  config file.
+	* wext: Increase scan timeout from 5 to 10 seconds.
+	* Add blacklist command, allowing an external program to
+	  manage the BSS blacklist and display its current contents.
+	* WPS:
+	  - Add wpa_cli wps_pin get command for generating random PINs. This can
+	    be used in a UI to generate a PIN without starting WPS (or P2P)
+	    operation.
+	  - Set RF bands based on driver capabilities, instead of hardcoding
+	    them.
+	  - Add mechanism for indicating non-standard WPS errors.
+	  - Add CONFIG_WPS_REG_DISABLE_OPEN=y option to disable open networks
+	    by default.
+	  - Add wps_ap_pin cli command for wpa_supplicant AP mode.
+	  - Add wps_check_pin cli command for processing PIN from user input.
+	    UIs can use this command to process a PIN entered by a user and to
+	    validate the checksum digit (if present).
+	  - Cancel WPS operation on PBC session overlap detection.
+	  - New wps_cancel command in wpa_cli will cancel a pending WPS
+	    operation.
+	  - wpa_cli action: Add WPS_EVENT_SUCCESS and WPS_EVENT_FAIL handlers.
+	  - Trigger WPS config update on Manufacturer, Model Name, Model
+	    Number, and Serial Number changes.
+	  - Fragment size is now configurable for EAP-WSC peer. Use
+	    wpa_cli set wps_fragment_size <val>.
+	  - Disable AP PIN after 10 consecutive failures. Slow down attacks on
+	    failures up to 10.
+	  - Allow AP to start in Enrollee mode without AP PIN for probing, to
+	    be compatible with Windows 7.
+	  - Add Config Error into WPS-FAIL events to provide more info to the
+	    user on how to resolve the issue.
+	  - Label and Display config methods are not allowed to be enabled
+	    at the same time, since it is unclear which PIN to use if both
+	    methods are advertised.
+	  - When controlling multiple interfaces:
+	     - apply WPS commands to all interfaces configured to use WPS
+	     - apply WPS config changes to all interfaces that use WPS
+	     - when an attack is detected on any interface, disable AP PIN on
+	       all interfaces
+	* WPS ER:
+	  - Add special AP Setup Locked mode to allow read only ER.
+	    ap_setup_locked=2 can now be used to enable a special mode where
+	    WPS ER can learn the current AP settings, but cannot change them.
+	  - Show SetSelectedRegistrar events as ctrl_iface events
+	  - Add wps_er_set_config to enroll a network based on a local
+	    network configuration block instead of having to (re-)learn the
+	    current AP settings with wps_er_learn.
+	  - Allow AP filtering based on IP address, add ctrl_iface event for
+	    learned AP settings, add wps_er_config command to configure an AP.
+	* WPS 2.0: Add support for WPS 2.0 (CONFIG_WPS2)
+	  - Add build option CONFIG_WPS_EXTENSIBILITY_TESTING to enable tool
+	    for testing protocol extensibility.
+	  - Add build option CONFIG_WPS_STRICT to allow disabling of WPS
+	    workarounds.
+	  - Add support for AuthorizedMACs attribute.
+	* TDLS:
+	  - Propogate TDLS related nl80211 capability flags from kernel and
+	    add them as driver capability flags. If the driver doesn't support
+	    capabilities, assume TDLS is supported internally. When TDLS is
+	    explicitly not supported, disable all user facing TDLS operations.
+	  - Allow TDLS to be disabled at runtime (mostly for testing).
+	    Use set tdls_disabled.
+	  - Honor AP TDLS settings that prohibit/allow TDLS.
+	  - Add a special testing feature for changing TDLS behavior. Use
+	    CONFIG_TDLS_TESTING build param to enable. Configure at runtime
+	    with tdls_testing cli command.
+	  - Add support for TDLS 802.11z.
+	* wlantest: Add a tool wlantest for IEEE802.11 protocol testing.
+	  wlantest can be used to capture frames from a monitor interface
+	  for realtime capturing or from pcap files for offline analysis.
+	* Interworking: Support added for 802.11u. Enable in .config with
+	  CONFIG_INTERWORKING. See wpa_supplicant.conf for config parameters
+	  for interworking. wpa_cli commands added to support this are
+	  interworking_select, interworking_connect, anqp_get, fetch_anqp,
+	  and stop_fetch_anqp.
+	* Android: Add build and runtime support for Android wpa_supplicant.
+	* bgscan learn: Add new bgscan that learns BSS information based on
+	  previous scans, and uses that information to dynamically generate
+	  the list of channels for background scans.
+	* Add a new debug message level for excessive information. Use
+	  -ddd to enable.
+	* TLS: Add support for tls_disable_time_checks=1 in client mode.
+	* Internal TLS:
+	  - Add support for TLS v1.1 (RFC 4346). Enable with build parameter
+	    CONFIG_TLSV11.
+	  - Add domainComponent parser for X.509 names.
+	* Linux: Add RFKill support by adding an interface state "disabled".
+	* Reorder some IEs to get closer to IEEE 802.11 standard. Move
+	  WMM into end of Beacon, Probe Resp and (Re)Assoc Resp frames.
+	  Move HT IEs to be later in (Re)Assoc Resp.
+	* Solaris: Add support for wired 802.1X client.
+	* Wi-Fi Direct support. See README-P2P for more information.
+	* Many bugfixes.
+
+2010-04-18 - v0.7.2
+	* nl80211: fixed number of issues with roaming
+	* avoid unnecessary roaming if multiple APs with similar signal
+	  strength are present in scan results
+	* add TLS client events and server probing to ease design of
+	  automatic detection of EAP parameters
+	* add option for server certificate matching (SHA256 hash of the
+	  certificate) instead of trusted CA certificate configuration
+	* bsd: Cleaned up driver wrapper and added various low-level
+	  configuration options
+	* wpa_gui-qt4: do not show too frequent WPS AP available events as
+	  tray messages
+	* TNC: fixed issues with fragmentation
+	* EAP-TNC: add Flags field into fragment acknowledgement (needed to
+	  interoperate with other implementations; may potentially breaks
+	  compatibility with older wpa_supplicant/hostapd versions)
+	* wpa_cli: added option for using a separate process to receive event
+	  messages to reduce latency in showing these
+	  (CFLAGS += -DCONFIG_WPA_CLI_FORK=y in .config to enable this)
+	* maximum BSS table size can now be configured (bss_max_count)
+	* BSSes to be included in the BSS table can be filtered based on
+	  configured SSIDs to save memory (filter_ssids)
+	* fix number of issues with IEEE 802.11r/FT; this version is not
+	  backwards compatible with old versions
+	* nl80211: add support for IEEE 802.11r/FT protocol (both over-the-air
+	  and over-the-DS)
+	* add freq_list network configuration parameter to allow the AP
+	  selection to filter out entries based on the operating channel
+	* add signal strength change events for bgscan; this allows more
+	  dynamic changes to background scanning interval based on changes in
+	  the signal strength with the current AP; this improves roaming within
+	  ESS quite a bit, e.g., with bgscan="simple:30:-45:300" in the network
+	  configuration block to request background scans less frequently when
+	  signal strength remains good and to automatically trigger background
+	  scans whenever signal strength drops noticeably
+	  (this is currently only available with nl80211)
+	* add BSSID and reason code (if available) to disconnect event messages
+	* wpa_gui-qt4: more complete support for translating the GUI with
+	  linguist and add German translation
+	* fix DH padding with internal crypto code (mainly, for WPS)
+	* do not trigger initial scan automatically anymore if there are no
+	  enabled networks
+
+2010-01-16 - v0.7.1
+	* cleaned up driver wrapper API (struct wpa_driver_ops); the new API
+	  is not fully backwards compatible, so out-of-tree driver wrappers
+	  will need modifications
+	* cleaned up various module interfaces
+	* merge hostapd and wpa_supplicant developers' documentation into a
+	  single document
+	* nl80211: use explicit deauthentication to clear cfg80211 state to
+	  avoid issues when roaming between APs
+	* dbus: major design changes in the new D-Bus API
+	  (fi.w1.wpa_supplicant1)
+	* nl80211: added support for IBSS networks
+	* added internal debugging mechanism with backtrace support and memory
+	  allocation/freeing validation, etc. tests (CONFIG_WPA_TRACE=y)
+	* added WPS ER unsubscription command to more cleanly unregister from
+	  receiving UPnP events when ER is terminated
+	* cleaned up AP mode operations to avoid need for virtual driver_ops
+	  wrapper
+	* added BSS table to maintain more complete scan result information
+	  over multiple scans (that may include only partial results)
+	* wpa_gui-qt4: update Peers dialog information more dynamically while
+	  the dialog is kept open
+	* fixed PKCS#12 use with OpenSSL 1.0.0
+	* driver_wext: Added cfg80211-specific optimization to avoid some
+	  unnecessary scans and to speed up association
+
+2009-11-21 - v0.7.0
+	* increased wpa_cli ping interval to 5 seconds and made this
+	  configurable with a new command line options (-G<seconds>)
+	* fixed scan buffer processing with WEXT to handle up to 65535
+	  byte result buffer (previously, limited to 32768 bytes)
+	* allow multiple driver wrappers to be specified on command line
+	  (e.g., -Dnl80211,wext); the first one that is able to initialize the
+	  interface will be used
+	* added support for multiple SSIDs per scan request to optimize
+	  scan_ssid=1 operations in ap_scan=1 mode (i.e., search for hidden
+	  SSIDs); this requires driver support and can currently be used only
+	  with nl80211
+	* added support for WPS USBA out-of-band mechanism with USB Flash
+	  Drives (UFD) (CONFIG_WPS_UFD=y)
+	* driver_ndis: add PAE group address to the multicast address list to
+	  fix wired IEEE 802.1X authentication
+	* fixed IEEE 802.11r key derivation function to match with the standard
+	  (note: this breaks interoperability with previous version) [Bug 303]
+	* added better support for drivers that allow separate authentication
+	  and association commands (e.g., mac80211-based Linux drivers with
+	  nl80211; SME in wpa_supplicant); this allows over-the-air FT protocol
+	  to be used (IEEE 802.11r)
+	* fixed SHA-256 based key derivation function to match with the
+	  standard when using CCMP (for IEEE 802.11r and IEEE 802.11w)
+	  (note: this breaks interoperability with previous version) [Bug 307]
+	* use shared driver wrapper files with hostapd
+	* added AP mode functionality (CONFIG_AP=y) with mode=2 in the network
+	  block; this can be used for open and WPA2-Personal networks
+	  (optionally, with WPS); this links in parts of hostapd functionality
+	  into wpa_supplicant
+	* wpa_gui-qt4: added new Peers dialog to show information about peers
+	  (other devices, including APs and stations, etc. in the neighborhood)
+	* added support for WPS External Registrar functionality (configure APs
+	  and enroll new devices); can be used with wpa_gui-qt4 Peers dialog
+	  and wpa_cli commands wps_er_start, wps_er_stop, wps_er_pin,
+	  wps_er_pbc, wps_er_learn
+	  (this can also be used with a new 'none' driver wrapper if no
+	  wireless device or IEEE 802.1X on wired is needed)
+	* driver_nl80211: multiple updates to provide support for new Linux
+	  nl80211/mac80211 functionality
+	* updated management frame protection to use IEEE Std 802.11w-2009
+	* fixed number of small WPS issues and added workarounds to
+	  interoperate with common deployed broken implementations
+	* added support for NFC out-of-band mechanism with WPS
+	* driver_ndis: fixed wired IEEE 802.1X authentication with PAE group
+	  address frames
+	* added preliminary support for IEEE 802.11r RIC processing
+	* added support for specifying subset of enabled frequencies to scan
+	  (scan_freq option in the network configuration block); this can speed
+	  up scanning process considerably if it is known that only a small
+	  subset of channels is actually used in the network (this is currently
+	  supported only with -Dnl80211)
+	* added a workaround for race condition between receiving the
+	  association event and the following EAPOL-Key
+	* added background scan and roaming infrastructure to allow
+	  network-specific optimizations to be used to improve roaming within
+	  an ESS (same SSID)
+	* added new DBus interface (fi.w1.wpa_supplicant1)
+
+2009-01-06 - v0.6.7
+	* added support for Wi-Fi Protected Setup (WPS)
+	  (wpa_supplicant can now be configured to act as a WPS Enrollee to
+	  enroll credentials for a network using PIN and PBC methods; in
+	  addition, wpa_supplicant can act as a wireless WPS Registrar to
+	  configure an AP); WPS support can be enabled by adding CONFIG_WPS=y
+	  into .config and setting the runtime configuration variables in
+	  wpa_supplicant.conf (see WPS section in the example configuration
+	  file); new wpa_cli commands wps_pin, wps_pbc, and wps_reg are used to
+	  manage WPS negotiation; see README-WPS for more details
+	* added support for EAP-AKA' (draft-arkko-eap-aka-kdf)
+	* added support for using driver_test over UDP socket
+	* fixed PEAPv0 Cryptobinding interoperability issue with Windows Server
+	  2008 NPS; optional cryptobinding is now enabled (again) by default
+	* fixed PSK editing in wpa_gui
+	* changed EAP-GPSK to use the IANA assigned EAP method type 51
+	* added a Windows installer that includes WinPcap and all the needed
+	  DLLs; in addition, it set up the registry automatically so that user
+	  will only need start wpa_gui to get prompted to start the wpasvc
+	  servide and add a new interface if needed through wpa_gui dialog
+	* updated management frame protection to use IEEE 802.11w/D7.0
+
+2008-11-23 - v0.6.6
+	* added Milenage SIM/USIM emulator for EAP-SIM/EAP-AKA
+	  (can be used to simulate test SIM/USIM card with a known private key;
+	  enable with CONFIG_SIM_SIMULATOR=y/CONFIG_USIM_SIMULATOR=y in .config
+	  and password="Ki:OPc"/password="Ki:OPc:SQN" in network configuration)
+	* added a new network configuration option, wpa_ptk_rekey, that can be
+	  used to enforce frequent PTK rekeying, e.g., to mitigate some attacks
+	  against TKIP deficiencies
+	* added an optional mitigation mechanism for certain attacks against
+	  TKIP by delaying Michael MIC error reports by a random amount of time
+	  between 0 and 60 seconds; this can be enabled with a build option
+	  CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config
+	* fixed EAP-AKA to use RES Length field in AT_RES as length in bits,
+	  not bytes
+	* updated OpenSSL code for EAP-FAST to use an updated version of the
+	  session ticket overriding API that was included into the upstream
+	  OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
+	  needed with that version anymore)
+	* updated userspace MLME instructions to match with the current Linux
+	  mac80211 implementation; please also note that this can only be used
+	  with driver_nl80211.c (the old code from driver_wext.c was removed)
+	* added support (Linux only) for RoboSwitch chipsets (often found in
+	  consumer grade routers); driver interface 'roboswitch'
+	* fixed canceling of PMKSA caching when using drivers that generate
+	  RSN IE and refuse to drop PMKIDs that wpa_supplicant does not know
+	  about
+
+2008-11-01 - v0.6.5
+	* added support for SHA-256 as X.509 certificate digest when using the
+	  internal X.509/TLSv1 implementation
+	* updated management frame protection to use IEEE 802.11w/D6.0
+	* added support for using SHA256-based stronger key derivation for WPA2
+	  (IEEE 802.11w)
+	* fixed FT (IEEE 802.11r) authentication after a failed association to
+	  use correct FTIE
+	* added support for configuring Phase 2 (inner/tunneled) authentication
+	  method with wpa_gui-qt4
+
+2008-08-10 - v0.6.4
+	* added support for EAP Sequences in EAP-FAST Phase 2
+	* added support for using TNC with EAP-FAST
+	* added driver_ps3 for the PS3 Linux wireless driver
+	* added support for optional cryptobinding with PEAPv0
+	* fixed the OpenSSL patches (0.9.8g and 0.9.9) for EAP-FAST to
+	  allow fallback to full handshake if server rejects PAC-Opaque
+	* added fragmentation support for EAP-TNC
+	* added support for parsing PKCS #8 formatted private keys into the
+	  internal TLS implementation (both PKCS #1 RSA key and PKCS #8
+	  encapsulated RSA key can now be used)
+	* added option of using faster, but larger, routines in the internal
+	  LibTomMath (for internal TLS implementation) to speed up DH and RSA
+	  calculations (CONFIG_INTERNAL_LIBTOMMATH_FAST=y)
+	* fixed race condition between disassociation event and group key
+	  handshake to avoid getting stuck in incorrect state [Bug 261]
+	* fixed opportunistic key caching (proactive_key_caching)
+
+2008-02-22 - v0.6.3
+	* removed 'nai' and 'eappsk' network configuration variables that were
+	  previously used for configuring user identity and key for EAP-PSK,
+	  EAP-PAX, EAP-SAKE, and EAP-GPSK. 'identity' field is now used as the
+	  replacement for 'nai' (if old configuration used a separate
+	  'identity' value, that would now be configured as
+	  'anonymous_identity'). 'password' field is now used as the
+	  replacement for 'eappsk' (it can also be set using hexstring to
+	  present random binary data)
+	* removed '-w' command line parameter (wait for interface to be added,
+	  if needed); cleaner way of handling this functionality is to use an
+	  external mechanism (e.g., hotplug scripts) that start wpa_supplicant
+	  when an interface is added
+	* updated FT support to use the latest draft, IEEE 802.11r/D9.0
+	* added ctrl_iface monitor event (CTRL-EVENT-SCAN-RESULTS) for
+	  indicating when new scan results become available
+	* added new ctrl_iface command, BSS, to allow scan results to be
+	  fetched without hitting the message size limits (this command
+	  can be used to iterate through the scan results one BSS at the time)
+	* fixed EAP-SIM not to include AT_NONCE_MT and AT_SELECTED_VERSION
+	  attributes in EAP-SIM Start/Response when using fast reauthentication
+	* fixed EAPOL not to end up in infinite loop when processing dynamic
+	  WEP keys with IEEE 802.1X
+	* fixed problems in getting NDIS events from WMI on Windows 2000
+
+2008-01-01 - v0.6.2
+	* added support for Makefile builds to include debug-log-to-a-file
+	  functionality (CONFIG_DEBUG_FILE=y and -f<path> on command line)
+	* fixed EAP-SIM and EAP-AKA message parser to validate attribute
+	  lengths properly to avoid potential crash caused by invalid messages
+	* added data structure for storing allocated buffers (struct wpabuf);
+	  this does not affect wpa_supplicant usage, but many of the APIs
+	  changed and various interfaces (e.g., EAP) is not compatible with old
+	  versions
+	* added support for protecting EAP-AKA/Identity messages with
+	  AT_CHECKCODE (optional feature in RFC 4187)
+	* added support for protected result indication with AT_RESULT_IND for
+	  EAP-SIM and EAP-AKA (phase1="result_ind=1")
+	* added driver_wext workaround for race condition between scanning and
+	  association with drivers that take very long time to scan all
+	  channels (e.g., madwifi with dual-band cards); wpa_supplicant is now
+	  using a longer hardcoded timeout for the scan if the driver supports
+	  notifications for scan completion (SIOCGIWSCAN event); this helps,
+	  e.g., in cases where wpa_supplicant and madwifi driver ended up in
+	  loop where the driver did not even try to associate
+	* stop EAPOL timer tick when no timers are in use in order to reduce
+	  power consumption (no need to wake up the process once per second)
+	  [Bug 237]
+	* added support for privilege separation (run only minimal part of
+	  wpa_supplicant functionality as root and rest as unprivileged,
+	  non-root process); see 'Privilege separation' in README for details;
+	  this is disabled by default and can be enabled with CONFIG_PRIVSEP=y
+	  in .config
+	* changed scan results data structure to include all information
+	  elements to make it easier to support new IEs; old get_scan_result()
+	  driver_ops is still supported for backwards compatibility (results
+	  are converted internally to the new format), but all drivers should
+	  start using the new get_scan_results2() to make them more likely to
+	  work with new features
+	* Qt4 version of wpa_gui (wpa_gui-qt4 subdirectory) is now native Qt4
+	  application, i.e., it does not require Qt3Support anymore; Windows
+	  binary of wpa_gui.exe is now from this directory and only requires
+	  QtCore4.dll and QtGui4.dll libraries
+	* updated Windows binary build to use Qt 4.3.3 and made Qt DLLs
+	  available as a separate package to make wpa_gui installation easier:
+	  http://w1.fi/wpa_supplicant/qt4/wpa_gui-qt433-windows-dll.zip
+	* added support for EAP-IKEv2 (draft-tschofenig-eap-ikev2-15.txt);
+	  only shared key/password authentication is supported in this version
+
+2007-11-24 - v0.6.1
+	* added support for configuring password as NtPasswordHash
+	  (16-byte MD4 hash of password) in hash:<32 hex digits> format
+	* added support for fallback from abbreviated TLS handshake to
+	  full handshake when using EAP-FAST (e.g., due to an expired
+	  PAC-Opaque)
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-07.txt)
+	* added support for drivers that take care of RSN 4-way handshake
+	  internally (WPA_DRIVER_FLAGS_4WAY_HANDSHAKE in get_capa flags and
+	  WPA_ALG_PMK in set_key)
+	* added an experimental port for Mac OS X (CONFIG_DRIVER_OSX=y in
+	  .config); this version supports only ap_scan=2 mode and allow the
+	  driver to take care of the 4-way handshake
+	* fixed a buffer overflow in parsing TSF from scan results when using
+	  driver_wext.c with a driver that includes the TSF (e.g., iwl4965)
+	  [Bug 232]
+	* updated FT support to use the latest draft, IEEE 802.11r/D8.0
+	* fixed an integer overflow issue in the ASN.1 parser used by the
+	  (experimental) internal TLS implementation to avoid a potential
+	  buffer read overflow
+	* fixed a race condition with -W option (wait for a control interface
+	  monitor before starting) that could have caused the first messages to
+	  be lost
+	* added support for processing TNCC-TNCS-Messages to report
+	  recommendation (allow/none/isolate) when using TNC [Bug 243]
+
+2007-05-28 - v0.6.0
+	* added network configuration parameter 'frequency' for setting
+	  initial channel for IBSS (adhoc) networks
+	* added experimental IEEE 802.11r/D6.0 support
+	* updated EAP-SAKE to RFC 4763 and the IANA-allocated EAP type 48
+	* updated EAP-PSK to use the IANA-allocated EAP type 47
+	* fixed EAP-PAX key derivation
+	* fixed EAP-PSK bit ordering of the Flags field
+	* fixed EAP-PEAP/TTLS/FAST to use the correct EAP identifier in
+	  tunnelled identity request (previously, the identifier from the outer
+	  method was used, not the tunnelled identifier which could be
+	  different)
+	* added support for fragmentation of outer TLS packets during Phase 2
+	  of EAP-PEAP/TTLS/FAST
+	* fixed EAP-TTLS AVP parser processing for too short AVP lengths
+	* added support for EAP-FAST authentication with inner methods that
+	  generate MSK (e.g., EAP-MSCHAPv2 that was previously only supported
+	  for PAC provisioning)
+	* added support for authenticated EAP-FAST provisioning
+	* added support for configuring maximum number of EAP-FAST PACs to
+	  store in a PAC list (fast_max_pac_list_len=<max> in phase1 string)
+	* added support for storing EAP-FAST PACs in binary format
+	  (fast_pac_format=binary in phase1 string)
+	* fixed dbus ctrl_iface to validate message interface before
+	  dispatching to avoid a possible segfault [Bug 190]
+	* fixed PeerKey key derivation to use the correct PRF label
+	* updated Windows binary build to link against OpenSSL 0.9.8d and
+	  added support for EAP-FAST
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-04.txt)
+	* fixed EAP-AKA Notification processing to allow Notification to be
+	  processed after AKA Challenge response has been sent
+	* updated to use IEEE 802.11w/D2.0 for management frame protection
+	  (still experimental)
+	* fixed EAP-TTLS implementation not to crash on use of freed memory
+	  if TLS library initialization fails
+	* added support for EAP-TNC (Trusted Network Connect)
+	  (this version implements the EAP-TNC method and EAP-TTLS changes
+	  needed to run two methods in sequence (IF-T) and the IF-IMC and
+	  IF-TNCCS interfaces from TNCC)
+
+2006-11-24 - v0.5.6
+	* added experimental, integrated TLSv1 client implementation with the
+	  needed X.509/ASN.1/RSA/bignum processing (this can be enabled by
+	  setting CONFIG_TLS=internal and CONFIG_INTERNAL_LIBTOMMATH=y in
+	  .config); this can be useful, e.g., if the target system does not
+	  have a suitable TLS library and a minimal code size is required
+	  (total size of this internal TLS/crypto code is bit under 50 kB on
+	  x86 and the crypto code is shared by rest of the supplicant so some
+	  of it was already required; TLSv1/X.509/ASN.1/RSA added about 25 kB)
+	* removed STAKey handshake since PeerKey handshake has replaced it in
+	  IEEE 802.11ma and there are no known deployments of STAKey
+	* updated EAP Generalized Pre-Shared Key (EAP-GPSK) to use the latest
+	  draft (draft-ietf-emu-eap-gpsk-01.txt)
+	* added preliminary implementation of IEEE 802.11w/D1.0 (management
+	  frame protection)
+	  (Note: this requires driver support to work properly.)
+	  (Note2: IEEE 802.11w is an unapproved draft and subject to change.)
+	* fixed Windows named pipes ctrl_iface to not stop listening for
+	  commands if client program opens a named pipe and closes it
+	  immediately without sending a command
+	* fixed USIM PIN status determination for the case that PIN is not
+	  needed (this allows EAP-AKA to be used with USIM cards that do not
+	  use PIN)
+	* added support for reading 3G USIM AID from EF_DIR to allow EAP-AKA to
+	  be used with cards that do not support file selection based on
+	  partial AID
+	* added support for matching the subjectAltName of the authentication
+	  server certificate against multiple name components (e.g.,
+	  altsubject_match="DNS:server.example.com;DNS:server2.example.com")
+	* fixed EAP-SIM/AKA key derivation for re-authentication case (only
+	  affects IEEE 802.1X with dynamic WEP keys)
+	* changed ctrl_iface network configuration 'get' operations to not
+	  return password/key material; if these fields are requested, "*"
+	  will be returned if the password/key is set, but the value of the
+	  parameter is not exposed
+
+2006-08-27 - v0.5.5
+	* added support for building Windows version with UNICODE defined
+	  (wide-char functions)
+	* driver_ndis: fixed static WEP configuration to avoid race condition
+	  issues with some NDIS drivers between association and setting WEP
+	  keys
+	* driver_ndis: added validation for IELength value in scan results to
+	  avoid crashes when using buggy NDIS drivers [Bug 165]
+	* fixed Release|Win32 target in the Visual Studio project files
+	  (previously, only Debug|Win32 target was set properly)
+	* changed control interface API call wpa_ctrl_pending() to allow it to
+	  return -1 on error (e.g., connection lost); control interface clients
+	  will need to make sure that they verify that the value is indeed >0
+	  when determining whether there are pending messages
+	* added an alternative control interface backend for Windows targets:
+	  Named Pipe (CONFIG_CTRL_IFACE=named_pipe); this is now the default
+	  control interface mechanism for Windows builds (previously, UDP to
+	  localhost was used)
+	* changed ctrl_interface configuration for UNIX domain sockets:
+	  - deprecated ctrl_interface_group variable (it may be removed in
+	    future versions)
+	  - allow both directory and group be configured with ctrl_interface
+	    in following format: DIR=/var/run/wpa_supplicant GROUP=wheel
+	  - ctrl_interface=/var/run/wpa_supplicant is still supported for the
+	    case when group is not changed
+	* added support for controlling more than one interface per process in
+	  Windows version
+	* added a workaround for a case where the AP is using unknown address
+	  (e.g., MAC address of the wired interface) as the source address for
+	  EAPOL-Key frames; previously, that source address was used as the
+	  destination for EAPOL-Key frames and in key derivation; now, BSSID is
+	  used even if the source address does not match with it
+	  (this resolves an interoperability issue with Thomson SpeedTouch 580)
+	* added a workaround for UDP-based control interface (which was used in
+	  Windows builds before this release) to prevent packets with forged
+	  addresses from being accepted as local control requests
+	* removed ndis_events.cpp and possibility of using external
+	  ndis_events.exe; C version (ndis_events.c) is fully functional and
+	  there is no desire to maintain two separate versions of this
+	  implementation
+	* ndis_events: Changed NDIS event notification design to use WMI to
+	  learn the adapter description through Win32_PnPEntity class; this
+	  should fix some cases where the adapter name was not recognized
+	  correctly (e.g., with some USB WLAN adapters, e.g., Ralink RT2500
+	  USB) [Bug 113]
+	* fixed selection of the first network in ap_scan=2 mode; previously,
+	  wpa_supplicant could get stuck in SCANNING state when only the first
+	  network for enabled (e.g., after 'wpa_cli select_network 0')
+	* winsvc: added support for configuring ctrl_interface parameters in
+	  registry (ctrl_interface string value in
+	  HKLM\SOFTWARE\wpa_supplicant\interfaces\0000 key); this new value is
+	  required to enable control interface (previously, this was hardcoded
+	  to be enabled)
+	* allow wpa_gui subdirectory to be built with both Qt3 and Qt4
+	* converted wpa_gui-qt4 subdirectory to use Qt4 specific project format
+
+2006-06-20 - v0.5.4
+	* fixed build with CONFIG_STAKEY=y [Bug 143]
+	* added support for doing MLME (IEEE 802.11 management frame
+	  processing) in wpa_supplicant when using Devicescape IEEE 802.11
+	  stack (wireless-dev.git tree)
+	* added a new network block configuration option, fragment_size, to
+	  configure the maximum EAP fragment size
+	* driver_ndis: Disable WZC automatically for the selected interface to
+	  avoid conflicts with two programs trying to control the radio; WZC
+	  will be re-enabled (if it was enabled originally) when wpa_supplicant
+	  is terminated
+	* added an experimental TLSv1 client implementation
+	  (CONFIG_TLS=internal) that can be used instead of an external TLS
+	  library, e.g., to reduce total size requirement on systems that do
+	  not include any TLS library by default (this is not yet complete;
+	  basic functionality is there, but certificate validation is not yet
+	  included)
+	* added PeerKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS) to replace STAKey handshake
+	* fixed WPA PSK update through ctrl_iface for the case where the old
+	  PSK was derived from an ASCII passphrase and the new PSK is set as
+	  a raw PSK (hex string)
+	* added new configuration option for identifying which network block
+	  was used (id_str in wpa_supplicant.conf; included on
+	  WPA_EVENT_CONNECT monitor event and as WPA_ID_STR environmental
+	  variable in wpa_cli action scripts; in addition WPA_ID variable is
+	  set to the current unique identifier that wpa_supplicant assigned
+	  automatically for the network and that can be used with
+	  GET_NETWORK/SET_NETWORK ctrl_iface commands)
+	* wpa_cli action script is now called only when the connect/disconnect
+	  status changes or when associating with a different network
+	* fixed configuration parser not to remove CCMP from group cipher list
+	  if WPA-None (adhoc) is used (pairwise=NONE in that case)
+	* fixed integrated NDIS events processing not to hang the process due
+	  to a missed change in eloop_win.c API in v0.5.3 [Bug 155]
+	* added support for EAP Generalized Pre-Shared Key (EAP-GPSK,
+	  draft-clancy-emu-eap-shared-secret-00.txt)
+	* added Microsoft Visual Studio 2005 solution and project files for
+	  build wpa_supplicant for Windows (see vs2005 subdirectory)
+	* eloop_win: fixed unregistration of Windows events
+	* l2_packet_winpcap: fixed a deadlock in deinitializing l2_packet
+	  at the end of RSN pre-authentication and added unregistration of
+	  a Windows event to avoid getting eloop_win stuck with an invalid
+	  handle
+	* driver_ndis: added support for selecting AP based on BSSID
+	* added new environmental variable for wpa_cli action scripts:
+	  WPA_CTRL_DIR is the current control interface directory
+	* driver_ndis: added support for using NDISUIO instead of WinPcap for
+	  OID set/query operations (CONFIG_USE_NDISUIO=y in .config); with new
+	  l2_packet_ndis (CONFIG_L2_PACKET=ndis), this can be used to build
+	  wpa_supplicant without requiring WinPcap; note that using NDISUIO
+	  requires that WZC is disabled (net stop wzcsvc) since NDISUIO allows
+	  only one application to open the device
+	* changed NDIS driver naming to only include device GUID, e.g.,
+	  {7EE3EFE5-C165-472F-986D-F6FBEDFE8C8D}, instead of including WinPcap
+	  specific \Device\NPF_ prefix before the GUID; the prefix is still
+	  allowed for backwards compatibility, but it is not required anymore
+	  when specifying the interface
+	* driver_ndis: re-initialize driver interface is the adapter is removed
+	  and re-inserted [Bug 159]
+	* driver_madwifi: fixed TKIP and CCMP sequence number configuration on
+	  big endian hosts [Bug 146]
+
+2006-04-27 - v0.5.3
+	* fixed EAP-GTC response to include correct user identity when run as
+	  phase 2 method of EAP-FAST (i.e., EAP-FAST did not work in v0.5.2)
+	* driver_ndis: Fixed encryption mode configuration for unencrypted
+	  networks (some NDIS drivers ignored this, but others, e.g., Broadcom,
+	  refused to associate with open networks) [Bug 106]
+	* driver_ndis: use BSSID OID polling to detect when IBSS network is
+	  formed even when ndis_events code is included since some NDIS drivers
+	  do not generate media connect events in IBSS mode
+	* config_winreg: allow global ctrl_interface parameter to be configured
+	  in Windows registry
+	* config_winreg: added support for saving configuration data into
+	  Windows registry
+	* added support for controlling network device operational state
+	  (dormant/up) for Linux 2.6.17 to improve DHCP processing (see
+	  http://www.flamewarmaster.de/software/dhcpclient/ for a DHCP client
+	  that can use this information)
+	* driver_wext: added support for WE-21 change to SSID configuration
+	* driver_wext: fixed privacy configuration for static WEP keys mode
+	  [Bug 140]
+	* added an optional driver_ops callback for MLME-SETPROTECTION.request
+	  primitive
+	* added support for EAP-SAKE (no EAP method number allocated yet, so
+	  this is using the same experimental type 255 as EAP-PSK)
+	* added support for dynamically loading EAP methods (.so files) instead
+	  of requiring them to be statically linked in; this is disabled by
+	  default (see CONFIG_DYNAMIC_EAP_METHODS in defconfig for information
+	  on how to use this)
+
+2006-03-19 - v0.5.2
+	* do not try to use USIM APDUs when initializing PC/SC for SIM card
+	  access for a network that has not enabled EAP-AKA
+	* fixed EAP phase 2 Nak for EAP-{PEAP,TTLS,FAST} (this was broken in
+	  v0.5.1 due to the new support for expanded EAP types)
+	* added support for generating EAP Expanded Nak
+	* try to fetch scan results once before requesting new scan when
+	  starting up in ap_scan=1 mode (this can speed up initial association
+	  a lot with, e.g., madwifi-ng driver)
+	* added support for receiving EAPOL frames from a Linux bridge
+	  interface (-bbr0 on command line)
+	* fixed EAPOL re-authentication for sessions that used PMKSA caching
+	* changed EAP method registration to use a dynamic list of methods
+	  instead of a static list generated at build time
+	* fixed PMKSA cache deinitialization not to use freed memory when
+	  removing PMKSA entries
+	* fixed a memory leak in EAP-TTLS re-authentication
+	* reject WPA/WPA2 message 3/4 if it does not include any valid
+	  WPA/RSN IE
+	* driver_wext: added fallback to use SIOCSIWENCODE for setting auth_alg
+	  if the driver does not support SIOCSIWAUTH
+
+2006-01-29 - v0.5.1
+	* driver_test: added better support for multiple APs and STAs by using
+	  a directory with sockets that include MAC address for each device in
+	  the name (driver_param=test_dir=/tmp/test)
+	* added support for EAP expanded type (vendor specific EAP methods)
+	* added AP_SCAN command into ctrl_iface so that ap_scan configuration
+	  option can be changed if needed
+	* wpa_cli/wpa_gui: skip non-socket files in control directory when
+	  using UNIX domain sockets; this avoids selecting an incorrect
+	  interface (e.g., a PID file could be in this directory, even though
+	  use of this directory for something else than socket files is not
+	  recommended)
+	* fixed TLS library deinitialization after RSN pre-authentication not
+	  to disable TLS library for normal authentication
+	* driver_wext: Remove null-termination from SSID length if the driver
+	  used it; some Linux drivers do this and they were causing problems in
+	  wpa_supplicant not finding matching configuration block. This change
+	  would break a case where the SSID actually ends in '\0', but that is
+	  not likely to happen in real use.
+	* fixed PMKSA cache processing not to trigger deauthentication if the
+	  current PMKSA cache entry is replaced with a valid new entry
+	* fixed PC/SC initialization for ap_scan != 1 modes (this fixes
+	  EAP-SIM and EAP-AKA with real SIM/USIM card when using ap_scan=0 or
+	  ap_scan=2)
+
+2005-12-18 - v0.5.0 (beginning of 0.5.x development releases)
+	* added experimental STAKey handshake implementation for IEEE 802.11e
+	  direct link setup (DLS); note: this is disabled by default in both
+	  build and runtime configuration (can be enabled with CONFIG_STAKEY=y
+	  and stakey=1)
+	* fixed EAP-SIM and EAP-AKA pseudonym and fast re-authentication to
+	  decrypt AT_ENCR_DATA attributes correctly
+	* fixed EAP-AKA to allow resynchronization within the same session
+	* made code closer to ANSI C89 standard to make it easier to port to
+	  other C libraries and compilers
+	* started moving operating system or C library specific functions into
+	  wrapper functions defined in os.h and implemented in os_*.c to make
+	  code more portable
+	* wpa_supplicant can now be built with Microsoft Visual C++
+	  (e.g., with the freely available Toolkit 2003 version or Visual
+	  C++ 2005 Express Edition and Platform SDK); see nmake.mak for an
+	  example makefile for nmake
+	* added support for using Windows registry for command line parameters
+	  (CONFIG_MAIN=main_winsvc) and configuration data
+	  (CONFIG_BACKEND=winreg); see win_example.reg for an example registry
+	  contents; this version can be run both as a Windows service and as a
+	  normal application; 'wpasvc.exe app' to start as applicant,
+	  'wpasvc.exe reg <full path to wpasvc.exe>' to register a service,
+	  'net start wpasvc' to start the service, 'wpasvc.exe unreg' to
+	  unregister a service
+	* made it possible to link ndis_events.exe functionality into
+	  wpa_supplicant.exe by defining CONFIG_NDIS_EVENTS_INTEGRATED
+	* added better support for multiple control interface backends
+	  (CONFIG_CTRL_IFACE option); currently, 'unix' and 'udp' are supported
+	* fixed PC/SC code to use correct length for GSM AUTH command buffer
+	  and to not use pioRecvPci with SCardTransmit() calls; these were not
+	  causing visible problems with pcsc-lite, but Windows Winscard.dll
+	  refused the previously used parameters; this fixes EAP-SIM and
+	  EAP-AKA authentication using SIM/USIM card under Windows
+	* added new event loop implementation for Windows using
+	  WaitForMultipleObject() instead of select() in order to allow waiting
+	  for non-socket objects; this can be selected with
+	  CONFIG_ELOOP=eloop_win in .config
+	* added support for selecting l2_packet implementation in .config
+	  (CONFIG_L2_PACKET; following options are available now: linux, pcap,
+	  winpcap, freebsd, none)
+	* added new l2_packet implementation for WinPcap
+	  (CONFIG_L2_PACKET=winpcap) that uses a separate receive thread to
+	  reduce latency in EAPOL receive processing from about 100 ms to about
+	  3 ms
+	* added support for EAP-FAST key derivation using other ciphers than
+	  RC4-128-SHA for authentication and AES128-SHA for provisioning
+	* added support for configuring CA certificate as DER file and as a
+	  configuration blob
+	* fixed private key configuration as configuration blob and added
+	  support for using PKCS#12 as a blob
+	* tls_gnutls: added support for using PKCS#12 files; added support for
+	  session resumption
+	* added support for loading trusted CA certificates from Windows
+	  certificate store: ca_cert="cert_store://<name>", where <name> is
+	  likely CA (Intermediate CA certificates) or ROOT (root certificates)
+	* added C version of ndis_events.cpp and made it possible to build this
+	  with MinGW so that CONFIG_NDIS_EVENTS_INTEGRATED can be used more
+	  easily on cross-compilation builds
+	* added wpasvc.exe into Windows binary release; this is an alternative
+	  version of wpa_supplicant.exe with configuration backend using
+	  Windows registry and with the entry point designed to run as a
+	  Windows service
+	* integrated ndis_events.exe functionality into wpa_supplicant.exe and
+	  wpasvc.exe and removed this additional tool from the Windows binary
+	  release since it is not needed anymore
+	* load winscard.dll functions dynamically when building with MinGW
+	  since MinGW does not yet include winscard library
+
+2005-11-20 - v0.4.7 (beginning of 0.4.x stable releases)
+	* l2_packet_pcap: fixed wired IEEE 802.1X authentication with libpcap
+	  and WinPcap to receive frames sent to PAE group address
+	* disable EAP state machine when IEEE 802.1X authentication is not used
+	  in order to get rid of bogus "EAP failed" messages
+	* fixed OpenSSL error reporting to go through all pending errors to
+	  avoid confusing reports of old errors being reported at later point
+	  during handshake
+	* fixed configuration file updating to not write empty variables
+	  (e.g., proto or key_mgmt) that the file parser would not accept
+	* fixed ADD_NETWORK ctrl_iface command to use the same default values
+	  for variables as empty network definitions read from config file
+	  would get
+	* fixed EAP state machine to not discard EAP-Failure messages in many
+	  cases (e.g., during TLS handshake)
+	* fixed a infinite loop in private key reading if the configured file
+	  cannot be parsed successfully
+	* driver_madwifi: added support for madwifi-ng
+	* wpa_gui: do not display password/PSK field contents
+	* wpa_gui: added CA certificate configuration
+	* driver_ndis: fixed scan request in ap_scan=2 mode not to change SSID
+	* driver_ndis: include Beacon IEs in AssocInfo in order to notice if
+	  the new AP is using different WPA/RSN IE
+	* use longer timeout for IEEE 802.11 association to avoid problems with
+	  drivers that may take more than five second to associate
+
+2005-10-27 - v0.4.6
+	* allow fallback to WPA, if mixed WPA+WPA2 networks have mismatch in
+	  RSN IE, but WPA IE would match with wpa_supplicant configuration
+	* added support for named configuration blobs in order to avoid having
+	  to use file system for external files (e.g., certificates);
+	  variables can be set to "blob://<blob name>" instead of file path to
+	  use a named blob; supported fields: pac_file, client_cert,
+	  private_key
+	* fixed RSN pre-authentication (it was broken in the clean up of WPA
+	  state machine interface in v0.4.5)
+	* driver_madwifi: set IEEE80211_KEY_GROUP flag for group keys to make
+	  sure the driver configures broadcast decryption correctly
+	* added ca_path (and ca_path2) configuration variables that can be used
+	  to configure OpenSSL CA path, e.g., /etc/ssl/certs, for using the
+	  system-wide trusted CA list
+	* added support for starting wpa_supplicant without a configuration
+	  file (-C argument must be used to set ctrl_interface parameter for
+	  this case; in addition, -p argument can be used to provide
+	  driver_param; these new arguments can also be used with a
+	  configuration to override the values from the configuration)
+	* added global control interface that can be optionally used for adding
+	  and removing network interfaces dynamically (-g command line argument
+	  for both wpa_supplicant and wpa_cli) without having to restart
+	  wpa_supplicant process
+	* wpa_gui:
+	  - try to save configuration whenever something is modified
+	  - added WEP key configuration
+	  - added possibility to edit the current network configuration
+	* driver_ndis: fixed driver polling not to increase frequency on each
+	  received EAPOL frame due to incorrectly cancelled timeout
+	* added simple configuration file examples (in examples subdirectory)
+	* fixed driver_wext.c to filter wireless events based on ifindex to
+	  avoid interfaces receiving events from other interfaces
+	* delay sending initial EAPOL-Start couple of seconds to speed up
+	  authentication for the most common case of Authenticator starting
+	  EAP authentication immediately after association
+
+2005-09-25 - v0.4.5
+	* added a workaround for clearing keys with ndiswrapper to allow
+	  roaming from WPA enabled AP to plaintext one
+	* added docbook documentation (doc/docbook) that can be used to
+	  generate, e.g., man pages
+	* l2_packet_linux: use socket type SOCK_DGRAM instead of SOCK_RAW for
+	  PF_PACKET in order to prepare for network devices that do not use
+	  Ethernet headers (e.g., network stack with native IEEE 802.11 frames)
+	* use receipt of EAPOL-Key frame as a lower layer success indication
+	  for EAP state machine to allow recovery from dropped EAP-Success
+	  frame
+	* cleaned up internal EAPOL frame processing by not including link
+	  layer (Ethernet) header during WPA and EAPOL/EAP processing; this
+	  header is added only when transmitted the frame; this makes it easier
+	  to use wpa_supplicant on link layers that use different header than
+	  Ethernet
+	* updated EAP-PSK to use draft 9 by default since this can now be
+	  tested with hostapd; removed support for draft 3, including
+	  server_nai configuration option from network blocks
+	* driver_wired: add PAE address to the multicast address list in order
+	  to be able to receive EAPOL frames with drivers that do not include
+	  these multicast addresses by default
+	* driver_wext: add support for WE-19
+	* added support for multiple configuration backends (CONFIG_BACKEND
+	  option); currently, only 'file' is supported (i.e., the format used
+	  in wpa_supplicant.conf)
+	* added support for updating configuration ('wpa_cli save_config');
+	  this is disabled by default and can be enabled with global
+	  update_config=1 variable in wpa_supplicant.conf; this allows wpa_cli
+	  and wpa_gui to store the configuration changes in a permanent store
+	* added GET_NETWORK ctrl_iface command
+	  (e.g., 'wpa_cli get_network 0 ssid')
+
+2005-08-21 - v0.4.4
+	* replaced OpenSSL patch for EAP-FAST support
+	  (openssl-tls-extensions.patch) with a more generic and correct
+	  patch (the new patch is not compatible with the previous one, so the
+	  OpenSSL library will need to be patched with the new patch in order
+	  to be able to build wpa_supplicant with EAP-FAST support)
+	* added support for using Windows certificate store (through CryptoAPI)
+	  for client certificate and private key operations (EAP-TLS)
+	  (see wpa_supplicant.conf for more information on how to configure
+	  this with private_key)
+	* ported wpa_gui to Windows
+	* added Qt4 version of wpa_gui (wpa_gui-qt4 directory); this can be
+	  built with the open source version of the Qt4 for Windows
+	* allow non-WPA modes (e.g., IEEE 802.1X with dynamic WEP) to be used
+	  with drivers that do not support WPA
+	* ndis_events: fixed Windows 2000 support
+	* added support for enabling/disabling networks from the list of all
+	  configured networks ('wpa_cli enable_network <network id>' and
+	  'wpa_cli disable_network <network id>')
+	* added support for adding and removing network from the current
+	  configuration ('wpa_cli add_network' and 'wpa_cli remove_network
+	  <network id>'); added networks are disabled by default and they can
+	  be enabled with enable_network command once the configuration is done
+	  for the new network; note: configuration file is not yet updated, so
+	  these new networks are lost when wpa_supplicant is restarted
+	* added support for setting network configuration parameters through
+	  the control interface, for example:
+	  wpa_cli set_network 0 ssid "\"my network\""
+	* fixed parsing of strings that include both " and # within double
+	  quoted area (e.g., "start"#end")
+	* added EAP workaround for PEAP session resumption: allow outer,
+	  i.e., not tunneled, EAP-Success to terminate session since; this can
+	  be disabled with eap_workaround=0
+	  (this was allowed for PEAPv1 before, but now it is also allowed for
+	  PEAPv0 since at least one RADIUS authentication server seems to be
+	  doing this for PEAPv0, too)
+	* wpa_gui: added preliminary support for adding new networks to the
+	  wpa_supplicant configuration (double click on the scan results to
+	  open network configuration)
+
+2005-06-26 - v0.4.3
+	* removed interface for external EAPOL/EAP supplicant (e.g.,
+	  Xsupplicant), (CONFIG_XSUPPLICANT_IFACE) since it is not required
+	  anymore and is unlikely to be used by anyone
+	* driver_ndis: fixed WinPcap 3.0 support
+	* fixed build with CONFIG_DNET_PCAP=y on Linux
+	* l2_packet: moved different implementations into separate files
+	  (l2_packet_*.c)
+
+2005-06-12 - v0.4.2
+	* driver_ipw: updated driver structures to match with ipw2200-1.0.4
+	  (note: ipw2100-1.1.0 is likely to require an update to work with
+	  this)
+	* added support for using ap_scan=2 mode with multiple network blocks;
+	  wpa_supplicant will go through the networks one by one until the
+	  driver reports a successful association; this uses the same order for
+	  networks as scan_ssid=1 scans, i.e., the priority field is ignored
+	  and the network block order in the file is used instead
+	* fixed a potential issue in RSN pre-authentication ending up using
+	  freed memory if pre-authentication times out
+	* added support for matching alternative subject name extensions of the
+	  authentication server certificate; new configuration variables
+	  altsubject_match and altsubject_match2
+	* driver_ndis: added support for IEEE 802.1X authentication with wired
+	  NDIS drivers
+	* added support for querying private key password (EAP-TLS) through the
+	  control interface (wpa_cli/wpa_gui) if one is not included in the
+	  configuration file
+	* driver_broadcom: fixed couple of memory leaks in scan result
+	  processing
+	* EAP-PAX is now registered as EAP type 46
+	* fixed EAP-PAX MAC calculation
+	* fixed EAP-PAX CK and ICK key derivation
+	* added support for using password with EAP-PAX (as an alternative to
+	  entering key with eappsk); SHA-1 hash of the password will be used as
+	  the key in this case
+	* added support for arbitrary driver interface parameters through the
+	  configuration file with a new driver_param field; this adds a new
+	  driver_ops function set_param()
+	* added possibility to override l2_packet module with driver interface
+	  API (new send_eapol handler); this can be used to implement driver
+	  specific TX/RX functions for EAPOL frames
+	* fixed ctrl_interface_group processing for the case where gid is
+	  entered as a number, not group name
+	* driver_test: added support for testing hostapd with wpa_supplicant
+	  by using test driver interface without any kernel drivers or network
+	  cards
+
+2005-05-22 - v0.4.1
+	* driver_madwifi: fixed WPA/WPA2 mode configuration to allow EAPOL
+	  packets to be encrypted; this was apparently broken by the changed
+	  ioctl order in v0.4.0
+	* driver_madwifi: added preliminary support for compiling against 'BSD'
+	  branch of madwifi CVS tree
+	* added support for EAP-MSCHAPv2 password retries within the same EAP
+	  authentication session
+	* added support for password changes with EAP-MSCHAPv2 (used when the
+	  password has expired)
+	* added support for reading additional certificates from PKCS#12 files
+	  and adding them to the certificate chain
+	* fixed association with IEEE 802.1X (no WPA) when dynamic WEP keys
+	  were used
+	* fixed a possible double free in EAP-TTLS fast-reauthentication when
+	  identity or password is entered through control interface
+	* display EAP Notification messages to user through control interface
+	  with "CTRL-EVENT-EAP-NOTIFICATION" prefix
+	* added GUI version of wpa_cli, wpa_gui; this is not build
+	  automatically with 'make'; use 'make wpa_gui' to build (this requires
+	  Qt development tools)
+	* added 'disconnect' command to control interface for setting
+	  wpa_supplicant in state where it will not associate before
+	  'reassociate' command has been used
+	* added support for selecting a network from the list of all configured
+	  networks ('wpa_cli select_network <network id>'; this disabled all
+	  other networks; to re-enable, 'wpa_cli select_network any')
+	* added support for getting scan results through control interface
+	* added EAP workaround for PEAPv1 session resumption: allow outer,
+	  i.e., not tunneled, EAP-Success to terminate session since; this can
+	  be disabled with eap_workaround=0
+
+2005-04-25 - v0.4.0 (beginning of 0.4.x development releases)
+	* added a new build time option, CONFIG_NO_STDOUT_DEBUG, that can be
+	  used to reduce the size of the wpa_supplicant considerably if
+	  debugging code is not needed
+	* fixed EAPOL-Key validation to drop packets with invalid Key Data
+	  Length; such frames could have crashed wpa_supplicant due to buffer
+	  overflow
+	* added support for wired authentication (IEEE 802.1X on wired
+	  Ethernet); driver interface 'wired'
+	* obsoleted set_wpa() handler in the driver interface API (it can be
+	  replaced by moving enable/disable functionality into init()/deinit())
+	  (calls to set_wpa() are still present for backwards compatibility,
+	  but they may be removed in the future)
+	* driver_madwifi: fixed association in plaintext mode
+	* modified the EAP workaround that accepts EAP-Success with incorrect
+	  Identifier to be even less strict about verification in order to
+	  interoperate with some authentication servers
+	* added support for sending TLS alerts
+	* added support for 'any' SSID wildcard; if ssid is not configured or
+	  is set to an empty string, any SSID will be accepted for non-WPA AP
+	* added support for asking PIN (for SIM) from frontends (e.g.,
+	  wpa_cli); if a PIN is needed, but not included in the configuration
+	  file, a control interface request is sent and EAP processing is
+	  delayed until the PIN is available
+	* added support for using external devices (e.g., a smartcard) for
+	  private key operations in EAP-TLS (CONFIG_SMARTCARD=y in .config);
+	  new wpa_supplicant.conf variables:
+	  - global: opensc_engine_path, pkcs11_engine_path, pkcs11_module_path
+	  - network: engine, engine_id, key_id
+	* added experimental support for EAP-PAX
+	* added monitor mode for wpa_cli (-a<path to a program to run>) that
+	  allows external commands (e.g., shell scripts) to be run based on
+	  wpa_supplicant events, e.g., when authentication has been completed
+	  and data connection is ready; other related wpa_cli arguments:
+	  -B (run in background), -P (write PID file); wpa_supplicant has a new
+	  command line argument (-W) that can be used to make it wait until a
+	  control interface command is received in order to avoid missing
+	  events
+	* added support for opportunistic WPA2 PMKSA key caching (disabled by
+	  default, can be enabled with proactive_key_caching=1)
+	* fixed RSN IE in 4-Way Handshake message 2/4 for the case where
+	  Authenticator rejects PMKSA caching attempt and the driver is not
+	  using assoc_info events
+	* added -P<pid file> argument for wpa_supplicant to write the current
+	  process id into a file
+
+2005-02-12 - v0.3.7 (beginning of 0.3.x stable releases)
+	* added new phase1 option parameter, include_tls_length=1, to force
+	  wpa_supplicant to add TLS Message Length field to all TLS messages
+	  even if the packet is not fragmented; this may be needed with some
+	  authentication servers
+	* fixed WPA/RSN IE verification in message 3 of 4-Way Handshake when
+	  using drivers that take care of AP selection (e.g., when using
+	  ap_scan=2)
+	* fixed reprocessing of pending request after ctrl_iface requests for
+	  identity/password/otp
+	* fixed ctrl_iface requests for identity/password/otp in Phase 2 of
+	  EAP-PEAP and EAP-TTLS
+	* all drivers using driver_wext: set interface up and select Managed
+	  mode when starting wpa_supplicant; set interface down when exiting
+	* renamed driver_ipw2100.c to driver_ipw.c since it now supports both
+	  ipw2100 and ipw2200; please note that this also changed the
+	  configuration variable in .config to CONFIG_DRIVER_IPW
+
+2005-01-24 - v0.3.6
+	* fixed a busy loop introduced in v0.3.5 for scan result processing
+	  when no matching AP is found
+
+2005-01-23 - v0.3.5
+	* added a workaround for an interoperability issue with a Cisco AP
+	  when using WPA2-PSK
+	* fixed non-WPA IEEE 802.1X to use the same authentication timeout as
+	  WPA with IEEE 802.1X (i.e., timeout 10 -> 70 sec to allow
+	  retransmission of dropped frames)
+	* fixed issues with 64-bit CPUs and SHA1 cleanup in previous version
+	  (e.g., segfault when processing EAPOL-Key frames)
+	* fixed EAP workaround and fast reauthentication configuration for
+	  RSN pre-authentication; previously these were disabled and
+	  pre-authentication would fail if the used authentication server
+	  requires EAP workarounds
+	* added support for blacklisting APs that fail or timeout
+	  authentication in ap_scan=1 mode so that all APs are tried in cases
+	  where the ones with strongest signal level are failing authentication
+	* fixed CA certificate loading after a failed EAP-TLS/PEAP/TTLS
+	  authentication attempt
+	* allow EAP-PEAP/TTLS fast reauthentication only if Phase 2 succeeded
+	  in the previous authentication (previously, only Phase 1 success was
+	  verified)
+
+2005-01-09 - v0.3.4
+	* added preliminary support for IBSS (ad-hoc) mode configuration
+	  (mode=1 in network block); this included a new key_mgmt mode
+	  WPA-NONE, i.e., TKIP or CCMP with a fixed key (based on psk) and no
+	  key management; see wpa_supplicant.conf for more details and an
+	  example on how to configure this (note: this is currently implemented
+	  only for driver_hostapd.c, but the changes should be trivial to add
+	  in associate() handler for other drivers, too (assuming the driver
+	  supports WPA-None)
+	* added preliminary port for native Windows (i.e., no cygwin) using
+	  mingw
+
+2005-01-02 - v0.3.3
+	* added optional support for GNU Readline and History Libraries for
+	  wpa_cli (CONFIG_READLINE)
+	* cleaned up EAP state machine <-> method interface and number of
+	  small problems with error case processing not terminating on
+	  EAP-Failure but waiting for timeout
+	* added couple of workarounds for interoperability issues with a
+	  Cisco AP when using WPA2
+	* added support for EAP-FAST (draft-cam-winget-eap-fast-00.txt);
+	  Note: This requires a patch for openssl to add support for TLS
+	  extensions and number of workarounds for operations without
+	  certificates. Proof of concept type of experimental patch is
+	  included in openssl-tls-extensions.patch.
+
+2004-12-19 - v0.3.2
+	* fixed private key loading for cases where passphrase is not set
+	* fixed Windows/cygwin L2 packet handler freeing; previous version
+	  could cause a segfault when RSN pre-authentication was completed
+	* added support for PMKSA caching with drivers that generate RSN IEs
+	  (e.g., NDIS); currently, this is only implemented in driver_ndis.c,
+	  but similar code can be easily added to driver_ndiswrapper.c once
+	  ndiswrapper gets full support for RSN PMKSA caching
+	* improved recovery from PMKID mismatches by requesting full EAP
+	  authentication in case of failed PMKSA caching attempt
+	* driver_ndis: added support for NDIS NdisMIncidateStatus() events
+	  (this requires that ndis_events is ran while wpa_supplicant is
+	  running)
+	* driver_ndis: use ADD_WEP/REMOVE_WEP when configuring WEP keys
+	* added support for driver interfaces to replace the interface name
+	  based on driver/OS specific mapping, e.g., in case of driver_ndis,
+	  this allows the beginning of the adapter description to be used as
+	  the interface name
+	* added support for CR+LF (Windows-style) line ends in configuration
+	  file
+	* driver_ndis: enable radio before starting scanning, disable radio
+	  when exiting
+	* modified association event handler to set portEnabled = FALSE before
+	  clearing port Valid in order to reset EAP state machine and avoid
+	  problems with new authentication getting ignored because of state
+	  machines ending up in AUTHENTICATED/SUCCESS state based on old
+	  information
+	* added support for driver events to add PMKID candidates in order to
+	  allow drivers to give priority to most likely roaming candidates
+	* driver_hostap: moved PrivacyInvoked configuration to associate()
+	  function so that this will not be set for plaintext connections
+	* added KEY_MGMT_802_1X_NO_WPA as a new key_mgmt type so that driver
+	  interface can distinguish plaintext and IEEE 802.1X (no WPA)
+	  authentication
+	* fixed static WEP key configuration to use broadcast/default type for
+	  all keys (previously, the default TX key was configured as pairwise/
+	  unicast key)
+	* driver_ndis: added legacy WPA capability detection for non-WPA2
+	  drivers
+	* added support for setting static WEP keys for IEEE 802.1X without
+	  dynamic WEP keying (eapol_flags=0)
+
+2004-12-12 - v0.3.1
+	* added support for reading PKCS#12 (PFX) files (as a replacement for
+	  PEM/DER) to get certificate and private key (CONFIG_PKCS12)
+	* fixed compilation with CONFIG_PCSC=y
+	* added new ap_scan mode, ap_scan=2, for drivers that take care of
+	  association, but need to be configured with security policy and SSID,
+	  e.g., ndiswrapper and NDIS driver; this mode should allow such
+	  drivers to work with hidden SSIDs and optimized roaming; when
+	  ap_scan=2 is used, only the first network block in the configuration
+	  file is used and this configuration should have explicit security
+	  policy (i.e., only one option in the lists) for key_mgmt, pairwise,
+	  group, proto variables
+	* added experimental port of wpa_supplicant for Windows
+	  - driver_ndis.c driver interface (NDIS OIDs)
+	  - currently, this requires cygwin and WinPcap
+	  - small utility, win_if_list, can be used to get interface name
+	* control interface can now be removed at build time; add
+	  CONFIG_CTRL_IFACE=y to .config to maintain old functionality
+	* optional Xsupplicant interface can now be removed at build time;
+	  (CONFIG_XSUPPLICANT_IFACE=y in .config to bring it back)
+	* added auth_alg to driver interface associate() parameters to make it
+	  easier for drivers to configure authentication algorithm as part of
+	  the association
+
+2004-12-05 - v0.3.0 (beginning of 0.3.x development releases)
+	* driver_broadcom: added new driver interface for Broadcom wl.o driver
+	  (a generic driver for Broadcom IEEE 802.11a/g cards)
+	* wpa_cli: fixed parsing of -p <path> command line argument
+	* PEAPv1: fixed tunneled EAP-Success reply handling to reply with TLS
+	  ACK, not tunneled EAP-Success (of which only the first byte was
+	  actually send due to a bug in previous code); this seems to
+	  interoperate with most RADIUS servers that implements PEAPv1
+	* PEAPv1: added support for terminating PEAP authentication on tunneled
+	  EAP-Success message; this can be configured by adding
+	  peap_outer_success=0 on phase1 parameters in wpa_supplicant.conf
+	  (some RADIUS servers require this whereas others require a tunneled
+	  reply
+	* PEAPv1: changed phase1 option peaplabel to use default to 0, i.e., to
+	  the old label for key derivation; previously, the default was 1,
+	  but it looks like most existing PEAPv1 implementations use the old
+	  label which is thus more suitable default option
+	* added support for EAP-PSK (draft-bersani-eap-psk-03.txt)
+	* fixed parsing of wep_tx_keyidx
+	* added support for configuring list of allowed Phase 2 EAP types
+	  (for both EAP-PEAP and EAP-TTLS) instead of only one type
+	* added support for configuring IEEE 802.11 authentication algorithm
+	  (auth_alg; mainly for using Shared Key authentication with static
+	  WEP keys)
+	* added support for EAP-AKA (with UMTS SIM)
+	* fixed couple of errors in PCSC handling that could have caused
+	  random-looking errors for EAP-SIM
+	* added support for EAP-SIM pseudonyms and fast re-authentication
+	* added support for EAP-TLS/PEAP/TTLS fast re-authentication (TLS
+	  session resumption)
+	* added support for EAP-SIM with two challanges
+	  (phase1="sim_min_num_chal=3" can be used to require three challenges)
+	* added support for configuring DH/DSA parameters for an ephemeral DH
+	  key exchange (EAP-TLS/PEAP/TTLS) using new configuration parameters
+	  dh_file and dh_file2 (phase 2); this adds support for using DSA keys
+	  and optional DH key exchange to achieve forward secracy with RSA keys
+	* added support for matching subject of the authentication server
+	  certificate with a substring when using EAP-TLS/PEAP/TTLS; new
+	  configuration variables subject_match and subject_match2
+	* changed SSID configuration in driver_wext.c (used by many driver
+	  interfaces) to use ssid_len+1 as the length for SSID since some Linux
+	  drivers expect this
+	* fixed couple of unaligned reads in scan result parsing to fix WPA
+	  connection on some platforms (e.g., ARM)
+	* added driver interface for Intel ipw2100 driver
+	* added support for LEAP with WPA
+	* added support for larger scan results report (old limit was 4 kB of
+	  data, i.e., about 35 or so APs) when using Linux wireless extensions
+	  v17 or newer
+	* fixed a bug in PMKSA cache processing: skip sending of EAPOL-Start
+	  only if there is a PMKSA cache entry for the current AP
+	* fixed error handling for case where reading of scan results fails:
+	  must schedule a new scan or wpa_supplicant will remain waiting
+	  forever
+	* changed debug output to remove shared password/key material by
+	  default; all key information can be included with -K command line
+	  argument to match the previous behavior
+	* added support for timestamping debug log messages (disabled by
+	  default, can be enabled with -t command line argument)
+	* set pairwise/group cipher suite for non-WPA IEEE 802.1X to WEP-104
+	  if keys are not configured to be used; this fixes IEEE 802.1X mode
+	  with drivers that use this information to configure whether Privacy
+	  bit can be in Beacon frames (e.g., ndiswrapper)
+	* avoid clearing driver keys if no keys have been configured since last
+	  key clear request; this seems to improve reliability of group key
+	  handshake for ndiswrapper & NDIS driver which seems to be suffering
+	  of some kind of timing issue when the keys are cleared again after
+	  association
+	* changed driver interface API:
+	  - WPA_SUPPLICANT_DRIVER_VERSION define can be used to determine which
+	    version is being used (now, this is set to 2; previously, it was
+	    not defined)
+	  - pass pointer to private data structure to all calls
+	  - the new API is not backwards compatible; all in-tree driver
+	    interfaces has been converted to the new API
+	* added support for controlling multiple interfaces (radios) per
+	  wpa_supplicant process; each interface needs to be listed on the
+	  command line (-c, -i, -D arguments) with -N as a separator
+	  (-cwpa1.conf -iwlan0 -Dhostap -N -cwpa2.conf -iath0 -Dmadwifi)
+	* added a workaround for EAP servers that incorrectly use same Id for
+	  sequential EAP packets
+	* changed libpcap/libdnet configuration to use .config variable,
+	  CONFIG_DNET_PCAP, instead of requiring Makefile modification
+	* improved downgrade attack detection in IE verification of msg 3/4:
+	  verify both WPA and RSN IEs, if present, not only the selected one;
+	  reject the AP if an RSN IE is found in msg 3/4, but not in Beacon or
+	  Probe Response frame, and RSN is enabled in wpa_supplicant
+	  configuration
+	* fixed WPA msg 3/4 processing to allow Key Data field contain other
+	  IEs than just one WPA IE
+	* added support for FreeBSD and driver interface for the BSD net80211
+	  layer (CONFIG_DRIVER_BSD=y in .config); please note that some of the
+	  required kernel mods have not yet been committed
+	* made EAP workarounds configurable; enabled by default, can be
+	  disabled with network block option eap_workaround=0
+
+2004-07-17 - v0.2.4 (beginning of 0.2.x stable releases)
+	* resolved couple of interoperability issues with EAP-PEAPv1 and
+	  Phase 2 (inner EAP) fragment reassembly
+	* driver_madwifi: fixed WEP key configuration for IEEE 802.1X when the
+	  AP is using non-zero key index for the unicast key and key index zero
+	  for the broadcast key
+	* driver_hostap: fixed IEEE 802.1X WEP key updates and
+	  re-authentication by allowing unencrypted EAPOL frames when not using
+	  WPA
+	* added a new driver interface, 'wext', which uses only standard,
+	  driver independent functionality in Linux wireless extensions;
+	  currently, this can be used only for non-WPA IEEE 802.1X mode, but
+	  eventually, this is to be extended to support full WPA/WPA2 once
+	  Linux wireless extensions get support for this
+	* added support for mode in which the driver is responsible for AP
+	  scanning and selection; this is disabled by default and can be
+	  enabled with global ap_scan=0 variable in wpa_supplicant.conf;
+	  this mode can be used, e.g., with generic 'wext' driver interface to
+	  use wpa_supplicant as IEEE 802.1X Supplicant with any Linux driver
+	  supporting wireless extensions.
+	* driver_madwifi: fixed WPA2 configuration and scan_ssid=1 (e.g.,
+	  operation with an AP that does not include SSID in the Beacon frames)
+	* added support for new EAP authentication methods:
+	  EAP-TTLS/EAP-OTP, EAP-PEAPv0/OTP, EAP-PEAPv1/OTP, EAP-OTP
+	* added support for asking one-time-passwords from frontends (e.g.,
+	  wpa_cli); this 'otp' command works otherwise like 'password' command,
+	  but the password is used only once and the frontend will be asked for
+	  a new password whenever a request from authenticator requires a
+	  password; this can be used with both EAP-OTP and EAP-GTC
+	* changed wpa_cli to automatically re-establish connection so that it
+	  does not need to be re-started when wpa_supplicant is terminated and
+	  started again
+	* improved user data (identity/password/otp) requests through
+	  frontends: process pending EAPOL packets after getting new
+	  information so that full authentication does not need to be
+	  restarted; in addition, send pending requests again whenever a new
+	  frontend is attached
+	* changed control frontends to use a new directory for socket files to
+	  make it easier for wpa_cli to automatically select between interfaces
+	  and to provide access control for the control interface;
+	  wpa_supplicant.conf: ctrl_interface is now a path
+	  (/var/run/wpa_supplicant is the recommended path) and
+	  ctrl_interface_group can be used to select which group gets access to
+	  the control interface;
+	  wpa_cli: by default, try to connect to the first interface available
+	  in /var/run/wpa_supplicant; this path can be overriden with -p option
+	  and an interface can be selected with -i option (i.e., in most common
+	  cases, wpa_cli does not need to get any arguments)
+	* added support for LEAP
+	* added driver interface for Linux ndiswrapper
+	* added priority option for network blocks in the configuration file;
+	  this allows networks to be grouped based on priority (the scan
+	  results are searched for matches with network blocks in this order)
+
+2004-06-20 - v0.2.3
+	* sort scan results to improve AP selection
+	* fixed control interface socket removal for some error cases
+	* improved scan requesting and authentication timeout
+	* small improvements/bug fixes for EAP-MSCHAPv2, EAP-PEAP, and
+	  TLS processing
+	* PEAP version can now be forced with phase1="peapver=<ver>"
+	  (mostly for testing; by default, the highest version supported by
+	  both the Supplicant and Authentication Server is selected
+	  automatically)
+	* added support for madwifi driver (Atheros ar521x)
+	* added a workaround for cases where AP sets Install Tx/Rx bit for
+	  WPA Group Key messages when pairwise keys are used (without this,
+	  the Group Key would be used for Tx and the AP would drop frames
+	  from the station)
+	* added GSM SIM/USIM interface for GSM authentication algorithm for
+	  EAP-SIM; this requires pcsc-lite
+	* added support for ATMEL AT76C5XXx driver
+	* fixed IEEE 802.1X WEP key derivation in the case where Authenticator
+	  does not include key data in the EAPOL-Key frame (i.e., part of
+	  EAP keying material is used as data encryption key)
+	* added support for using plaintext and static WEP networks
+	  (key_mgmt=NONE)
+
+2004-05-31 - v0.2.2
+	* added support for new EAP authentication methods:
+	  EAP-TTLS/EAP-MD5-Challenge
+	  EAP-TTLS/EAP-GTC
+	  EAP-TTLS/EAP-MSCHAPv2
+	  EAP-TTLS/EAP-TLS
+	  EAP-TTLS/MSCHAPv2
+	  EAP-TTLS/MSCHAP
+	  EAP-TTLS/PAP
+	  EAP-TTLS/CHAP
+	  EAP-PEAP/TLS
+	  EAP-PEAP/GTC
+	  EAP-PEAP/MD5-Challenge
+	  EAP-GTC
+	  EAP-SIM (not yet complete; needs GSM/SIM authentication interface)
+	* added support for anonymous identity (to be used when identity is
+	  sent in plaintext; real identity will be used within TLS protected
+	  tunnel (e.g., with EAP-TTLS)
+	* added event messages from wpa_supplicant to frontends, e.g., wpa_cli
+	* added support for requesting identity and password information using
+	  control interface; in other words, the password for EAP-PEAP or
+	  EAP-TTLS does not need to be included in the configuration file since
+	  a frontand (e.g., wpa_cli) can ask it from the user
+	* improved RSN pre-authentication to use a candidate list and process
+	  all candidates from each scan; not only one per scan
+	* fixed RSN IE and WPA IE capabilities field parsing
+	* ignore Tx bit in GTK IE when Pairwise keys are used
+	* avoid making new scan requests during IEEE 802.1X negotiation
+	* use openssl/libcrypto for MD5 and SHA-1 when compiling wpa_supplicant
+	  with TLS support (this replaces the included implementation with
+	  library code to save about 8 kB since the library code is needed
+	  anyway for TLS)
+	* fixed WPA-PSK only mode when compiled without IEEE 802.1X support
+	  (i.e., without CONFIG_IEEE8021X_EAPOL=y in .config)
+
+2004-05-06 - v0.2.1
+	* added support for internal IEEE 802.1X (actually, IEEE 802.1aa/D6.1)
+	  Supplicant
+	  - EAPOL state machines for Supplicant [IEEE 802.1aa/D6.1]
+	  - EAP peer state machine [draft-ietf-eap-statemachine-02.pdf]
+	  - EAP-MD5 (cannot be used with WPA-RADIUS)
+	    [draft-ietf-eap-rfc2284bis-09.txt]
+	  - EAP-TLS [RFC 2716]
+	  - EAP-MSCHAPv2 (currently used only with EAP-PEAP)
+	  - EAP-PEAP/MSCHAPv2 [draft-josefsson-pppext-eap-tls-eap-07.txt]
+	    [draft-kamath-pppext-eap-mschapv2-00.txt]
+	    (PEAP version 0, 1, and parts of 2; only 0 and 1 are enabled by
+	    default; tested with FreeRADIUS, Microsoft IAS, and Funk Odyssey)
+	  - new configuration file options: eap, identity, password, ca_cert,
+	    client_cert, privatekey, private_key_passwd
+	  - Xsupplicant is not required anymore, but it can be used by
+	    disabling the internal IEEE 802.1X Supplicant with -e command line
+	    option
+	  - this code is not included in the default build; Makefile need to
+	    be edited for this (uncomment lines for selected functionality)
+	  - EAP-TLS and EAP-PEAP require openssl libraries
+	* use module prefix in debug messages (WPA, EAP, EAP-TLS, ..)
+	* added support for non-WPA IEEE 802.1X mode with dynamic WEP keys
+	  (i.e., complete IEEE 802.1X/EAP authentication and use IEEE 802.1X
+	   EAPOL-Key frames instead of WPA key handshakes)
+	* added support for IEEE 802.11i/RSN (WPA2)
+	  - improved PTK Key Handshake
+	  - PMKSA caching, pre-authentication
+	* fixed wpa_supplicant to ignore possible extra data after WPA
+	  EAPOL-Key packets (this fixes 'Invalid EAPOL-Key MIC when using
+	  TPTK' error from message 3 of 4-Way Handshake in case the AP
+	  includes extra data after the EAPOL-Key)
+	* added interface for external programs (frontends) to control
+	  wpa_supplicant
+	  - CLI example (wpa_cli) with interactive mode and command line
+	    mode
+	  - replaced SIGUSR1 status/statistics with the new control interface
+	* made some feature compile time configurable
+	  - .config file for make
+	  - driver interfaces (hostap, hermes, ..)
+	  - EAPOL/EAP functions
+

+  * pre-authentication
+  * PMKSA caching
+
+Supported TLS/crypto libraries:
+- OpenSSL (default)
+- GnuTLS
+
+Internal TLS/crypto implementation (optional):
+- can be used in place of an external TLS/crypto library
+- TLSv1
+- X.509 certificate processing
+- PKCS #1
+- ASN.1
+- RSA
+- bignum
+- minimal size (ca. 50 kB binary, parts of which are already needed for WPA;
+  TLSv1/X.509/ASN.1/RSA/bignum parts are about 25 kB on x86)
+
+
+Requirements
+------------
+
+Current hardware/software requirements:
+- Linux kernel 2.4.x or 2.6.x with Linux Wireless Extensions v15 or newer
+- FreeBSD 6-CURRENT
+- NetBSD-current
+- Microsoft Windows with WinPcap (at least WinXP, may work with other versions)
+- drivers:
+	Linux drivers that support WPA/WPA2 configuration with the generic
+	Linux wireless extensions (WE-18 or newer). Even though there are
+	number of driver specific interface included in wpa_supplicant, please
+	note that Linux drivers are moving to use generic wireless extensions
+	and driver_wext (-Dwext on wpa_supplicant command line) should be the
+	default option to start with before falling back to driver specific
+	interface.
+
+	In theory, any driver that supports Linux wireless extensions can be
+	used with IEEE 802.1X (i.e., not WPA) when using ap_scan=0 option in
+	configuration file.
+
+	Wired Ethernet drivers (with ap_scan=0)
+
+	BSD net80211 layer (e.g., Atheros driver)
+	At the moment, this is for FreeBSD 6-CURRENT branch and NetBSD-current.
+
+	Windows NDIS
+	The current Windows port requires WinPcap (http://winpcap.polito.it/).
+	See README-Windows.txt for more information.
+
+wpa_supplicant was designed to be portable for different drivers and
+operating systems. Hopefully, support for more wlan cards and OSes will be
+added in the future. See developer's documentation
+(http://hostap.epitest.fi/wpa_supplicant/devel/) for more information about the
+design of wpa_supplicant and porting to other drivers. One main goal
+is to add full WPA/WPA2 support to Linux wireless extensions to allow
+new drivers to be supported without having to implement new
+driver-specific interface code in wpa_supplicant.
+
+Optional libraries for layer2 packet processing:
+- libpcap (tested with 0.7.2, most relatively recent versions assumed to work,
+	this is likely to be available with most distributions,
+	http://tcpdump.org/)
+- libdnet (tested with v1.4, most versions assumed to work,
+	http://libdnet.sourceforge.net/)
+
+These libraries are _not_ used in the default Linux build. Instead,
+internal Linux specific implementation is used. libpcap/libdnet are
+more portable and they can be used by adding CONFIG_L2_PACKET=pcap into
+.config. They may also be selected automatically for other operating
+systems. In case of Windows builds, WinPcap is used by default
+(CONFIG_L2_PACKET=winpcap).
+
+
+Optional libraries for EAP-TLS, EAP-PEAP, and EAP-TTLS:
+- OpenSSL (tested with 0.9.7c and 0.9.7d, and 0.9.8 versions; assumed to
+  work with most relatively recent versions; this is likely to be
+  available with most distributions, http://www.openssl.org/)
+- GnuTLS
+- internal TLSv1 implementation
+
+TLS options for EAP-FAST:
+- OpenSSL 0.9.8d _with_ openssl-0.9.8d-tls-extensions.patch applied
+  (i.e., the default OpenSSL package does not include support for
+  extensions needed for EAP-FAST)
+- internal TLSv1 implementation
+
+One of these libraries is needed when EAP-TLS, EAP-PEAP, EAP-TTLS, or
+EAP-FAST support is enabled. WPA-PSK mode does not require this or EAPOL/EAP
+implementation. A configuration file, .config, for compilation is
+needed to enable IEEE 802.1X/EAPOL and EAP methods. Note that EAP-MD5,
+EAP-GTC, EAP-OTP, and EAP-MSCHAPV2 cannot be used alone with WPA, so
+they should only be enabled if testing the EAPOL/EAP state
+machines. However, there can be used as inner authentication
+algorithms with EAP-PEAP and EAP-TTLS.
+
+See Building and installing section below for more detailed
+information about the wpa_supplicant build time configuration.
+
+
+
+WPA
+---
+
+The original security mechanism of IEEE 802.11 standard was not
+designed to be strong and has proven to be insufficient for most
+networks that require some kind of security. Task group I (Security)
+of IEEE 802.11 working group (http://www.ieee802.org/11/) has worked
+to address the flaws of the base standard and has in practice
+completed its work in May 2004. The IEEE 802.11i amendment to the IEEE
+802.11 standard was approved in June 2004 and published in July 2004.
+
+Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version of the
+IEEE 802.11i work (draft 3.0) to define a subset of the security
+enhancements that can be implemented with existing wlan hardware. This
+is called Wi-Fi Protected Access<TM> (WPA). This has now become a
+mandatory component of interoperability testing and certification done
+by Wi-Fi Alliance. Wi-Fi provides information about WPA at its web
+site (http://www.wi-fi.org/OpenSection/protected_access.asp).
+
+IEEE 802.11 standard defined wired equivalent privacy (WEP) algorithm
+for protecting wireless networks. WEP uses RC4 with 40-bit keys,
+24-bit initialization vector (IV), and CRC32 to protect against packet
+forgery. All these choices have proven to be insufficient: key space is
+too small against current attacks, RC4 key scheduling is insufficient
+(beginning of the pseudorandom stream should be skipped), IV space is
+too small and IV reuse makes attacks easier, there is no replay
+protection, and non-keyed authentication does not protect against bit
+flipping packet data.
+
+WPA is an intermediate solution for the security issues. It uses
+Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP is a
+compromise on strong security and possibility to use existing
+hardware. It still uses RC4 for the encryption like WEP, but with
+per-packet RC4 keys. In addition, it implements replay protection,
+keyed packet authentication mechanism (Michael MIC).
+
+Keys can be managed using two different mechanisms. WPA can either use
+an external authentication server (e.g., RADIUS) and EAP just like
+IEEE 802.1X is using or pre-shared keys without need for additional
+servers. Wi-Fi calls these "WPA-Enterprise" and "WPA-Personal",
+respectively. Both mechanisms will generate a master session key for
+the Authenticator (AP) and Supplicant (client station).
+
+WPA implements a new key handshake (4-Way Handshake and Group Key
+Handshake) for generating and exchanging data encryption keys between
+the Authenticator and Supplicant. This handshake is also used to
+verify that both Authenticator and Supplicant know the master session
+key. These handshakes are identical regardless of the selected key
+management mechanism (only the method for generating master session
+key changes).
+
+
+
+IEEE 802.11i / WPA2
+-------------------
+
+The design for parts of IEEE 802.11i that were not included in WPA has
+finished (May 2004) and this amendment to IEEE 802.11 was approved in
+June 2004. Wi-Fi Alliance is using the final IEEE 802.11i as a new
+version of WPA called WPA2. This includes, e.g., support for more
+robust encryption algorithm (CCMP: AES in Counter mode with CBC-MAC)
+to replace TKIP and optimizations for handoff (reduced number of
+messages in initial key handshake, pre-authentication, and PMKSA caching).
+
+
+
+wpa_supplicant
+--------------
+
+wpa_supplicant is an implementation of the WPA Supplicant component,
+i.e., the part that runs in the client stations. It implements WPA key
+negotiation with a WPA Authenticator and EAP authentication with
+Authentication Server. In addition, it controls the roaming and IEEE
+802.11 authentication/association of the wlan driver.
+
+wpa_supplicant is designed to be a "daemon" program that runs in the
+background and acts as the backend component controlling the wireless
+connection. wpa_supplicant supports separate frontend programs and an
+example text-based frontend, wpa_cli, is included with wpa_supplicant.
+
+Following steps are used when associating with an AP using WPA:
+
+- wpa_supplicant requests the kernel driver to scan neighboring BSSes
+- wpa_supplicant selects a BSS based on its configuration
+- wpa_supplicant requests the kernel driver to associate with the chosen
+  BSS
+- If WPA-EAP: integrated IEEE 802.1X Supplicant completes EAP
+  authentication with the authentication server (proxied by the
+  Authenticator in the AP)
+- If WPA-EAP: master key is received from the IEEE 802.1X Supplicant
+- If WPA-PSK: wpa_supplicant uses PSK as the master session key
+- wpa_supplicant completes WPA 4-Way Handshake and Group Key Handshake
+  with the Authenticator (AP)
+- wpa_supplicant configures encryption keys for unicast and broadcast
+- normal data packets can be transmitted and received
+
+
+
+Building and installing
+-----------------------
+
+In order to be able to build wpa_supplicant, you will first need to
+select which parts of it will be included. This is done by creating a
+build time configuration file, .config, in the wpa_supplicant root
+directory. Configuration options are text lines using following
+format: CONFIG_<option>=y. Lines starting with # are considered
+comments and are ignored. See defconfig file for an example configuration
+and a list of available options and additional notes.
+
+The build time configuration can be used to select only the needed
+features and limit the binary size and requirements for external
+libraries. The main configuration parts are the selection of which
+driver interfaces (e.g., nl80211, wext, ..) and which authentication
+methods (e.g., EAP-TLS, EAP-PEAP, ..) are included.
+
+Following build time configuration options are used to control IEEE
+802.1X/EAPOL and EAP state machines and all EAP methods. Including
+TLS, PEAP, or TTLS will require linking wpa_supplicant with OpenSSL
+library for TLS implementation. Alternatively, GnuTLS or the internal
+TLSv1 implementation can be used for TLS functionaly.
+
+CONFIG_IEEE8021X_EAPOL=y
+CONFIG_EAP_MD5=y
+CONFIG_EAP_MSCHAPV2=y
+CONFIG_EAP_TLS=y
+CONFIG_EAP_PEAP=y
+CONFIG_EAP_TTLS=y
+CONFIG_EAP_GTC=y
+CONFIG_EAP_OTP=y
+CONFIG_EAP_SIM=y
+CONFIG_EAP_AKA=y
+CONFIG_EAP_PSK=y
+CONFIG_EAP_SAKE=y
+CONFIG_EAP_GPSK=y
+CONFIG_EAP_PAX=y
+CONFIG_EAP_LEAP=y
+CONFIG_EAP_IKEV2=y
+
+Following option can be used to include GSM SIM/USIM interface for GSM/UMTS
+authentication algorithm (for EAP-SIM/EAP-AKA). This requires pcsc-lite
+(http://www.linuxnet.com/) for smart card access.
+
+CONFIG_PCSC=y
+
+Following options can be added to .config to select which driver
+interfaces are included.
+
+CONFIG_DRIVER_NL80211=y
+CONFIG_DRIVER_WEXT=y
+CONFIG_DRIVER_BSD=y
+CONFIG_DRIVER_NDIS=y
+
+Following example includes some more features and driver interfaces that
+are included in the wpa_supplicant package:
+
+CONFIG_DRIVER_NL80211=y
+CONFIG_DRIVER_WEXT=y
+CONFIG_DRIVER_BSD=y
+CONFIG_DRIVER_NDIS=y
+CONFIG_IEEE8021X_EAPOL=y
+CONFIG_EAP_MD5=y
+CONFIG_EAP_MSCHAPV2=y
+CONFIG_EAP_TLS=y
+CONFIG_EAP_PEAP=y
+CONFIG_EAP_TTLS=y
+CONFIG_EAP_GTC=y
+CONFIG_EAP_OTP=y
+CONFIG_EAP_SIM=y
+CONFIG_EAP_AKA=y
+CONFIG_EAP_PSK=y
+CONFIG_EAP_SAKE=y
+CONFIG_EAP_GPSK=y
+CONFIG_EAP_PAX=y
+CONFIG_EAP_LEAP=y
+CONFIG_EAP_IKEV2=y
+CONFIG_PCSC=y
+
+EAP-PEAP and EAP-TTLS will automatically include configured EAP
+methods (MD5, OTP, GTC, MSCHAPV2) for inner authentication selection.
+
+
+After you have created a configuration file, you can build
+wpa_supplicant and wpa_cli with 'make' command. You may then install
+the binaries to a suitable system directory, e.g., /usr/local/bin.
+
+Example commands:
+
+# build wpa_supplicant and wpa_cli
+make
+# install binaries (this may need root privileges)
+cp wpa_cli wpa_supplicant /usr/local/bin
+
+
+You will need to make a configuration file, e.g.,
+/etc/wpa_supplicant.conf, with network configuration for the networks
+you are going to use. Configuration file section below includes
+explanation fo the configuration file format and includes various
+examples. Once the configuration is ready, you can test whether the
+configuration work by first running wpa_supplicant with following
+command to start it on foreground with debugging enabled:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -d
+
+Assuming everything goes fine, you can start using following command
+to start wpa_supplicant on background without debugging:
+
+wpa_supplicant -iwlan0 -c/etc/wpa_supplicant.conf -B
+
+Please note that if you included more than one driver interface in the
+build time configuration (.config), you may need to specify which
+interface to use by including -D<driver name> option on the command
+line. See following section for more details on command line options
+for wpa_supplicant.
+
+
+
+Command line options
+--------------------
+
+usage:
+  wpa_supplicant [-BddfhKLqqtuvwW] [-P<pid file>] [-g<global ctrl>] \
+        -i<ifname> -c<config file> [-C<ctrl>] [-D<driver>] [-p<driver_param>] \
+        [-b<br_ifname> [-N -i<ifname> -c<conf> [-C<ctrl>] [-D<driver>] \
+        [-p<driver_param>] [-b<br_ifname>] ...]
+
+options:
+  -b = optional bridge interface name
+  -B = run daemon in the background
+  -c = Configuration file
+  -C = ctrl_interface parameter (only used if -c is not)
+  -i = interface name
+  -d = increase debugging verbosity (-dd even more)
+  -D = driver name (can be multiple drivers: nl80211,wext)
+  -f = Log output to default log location (normally /tmp)
+  -g = global ctrl_interface
+  -K = include keys (passwords, etc.) in debug output
+  -t = include timestamp in debug messages
+  -h = show this help text
+  -L = show license (BSD)
+  -p = driver parameters
+  -P = PID file
+  -q = decrease debugging verbosity (-qq even less)
+  -u = enable DBus control interface
+  -v = show version
+  -w = wait for interface to be added, if needed
+  -W = wait for a control interface monitor before starting
+  -N = start describing new interface
+
+drivers:
+  wext = Linux wireless extensions (generic)
+  wired = wpa_supplicant wired Ethernet driver
+  roboswitch = wpa_supplicant Broadcom switch driver
+  bsd = BSD 802.11 support (Atheros, etc.)
+  ndis = Windows NDIS driver
+
+In most common cases, wpa_supplicant is started with
+
+wpa_supplicant -B -c/etc/wpa_supplicant.conf -iwlan0
+
+This makes the process fork into background.
+
+The easiest way to debug problems, and to get debug log for bug
+reports, is to start wpa_supplicant on foreground with debugging
+enabled:
+
+wpa_supplicant -c/etc/wpa_supplicant.conf -iwlan0 -d
+
+If the specific driver wrapper is not known beforehand, it is possible
+to specify multiple comma separated driver wrappers on the command
+line. wpa_supplicant will use the first driver wrapper that is able to
+initialize the interface.
+
+wpa_supplicant -Dnl80211,wext -c/etc/wpa_supplicant.conf -iwlan0
+
+
+wpa_supplicant can control multiple interfaces (radios) either by
+running one process for each interface separately or by running just
+one process and list of options at command line. Each interface is
+separated with -N argument. As an example, following command would
+start wpa_supplicant for two interfaces:
+
+wpa_supplicant \
+	-c wpa1.conf -i wlan0 -D nl80211 -N \
+	-c wpa2.conf -i wlan1 -D wext
+
+
+If the interface is added in a Linux bridge (e.g., br0), the bridge
+interface needs to be configured to wpa_supplicant in addition to the
+main interface:
+
+wpa_supplicant -cw.conf -Dwext -iwlan0 -bbr0
+
+
+Configuration file
+------------------
+
+wpa_supplicant is configured using a text file that lists all accepted
+networks and security policies, including pre-shared keys. See
+example configuration file, wpa_supplicant.conf, for detailed
+information about the configuration format and supported fields.
+
+Changes to configuration file can be reloaded be sending SIGHUP signal
+to wpa_supplicant ('killall -HUP wpa_supplicant'). Similarly,
+reloading can be triggered with 'wpa_cli reconfigure' command.
+
+Configuration file can include one or more network blocks, e.g., one
+for each used SSID. wpa_supplicant will automatically select the best
+betwork based on the order of network blocks in the configuration
+file, network security level (WPA/WPA2 is preferred), and signal
+strength.
+
+Example configuration files for some common configurations:
+
+1) WPA-Personal (PSK) as home network and WPA-Enterprise with EAP-TLS as work
+   network
+
+# allow frontend (e.g., wpa_cli) to be used by all users in 'wheel' group
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+#
+# home network; allow all valid ciphers
+network={
+	ssid="home"
+	scan_ssid=1
+	key_mgmt=WPA-PSK
+	psk="very secret passphrase"
+}
+#
+# work network; use EAP-TLS with WPA; allow only CCMP and TKIP ciphers
+network={
+	ssid="work"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	pairwise=CCMP TKIP
+	group=CCMP TKIP
+	eap=TLS
+	identity="user@example.com"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+}
+
+
+2) WPA-RADIUS/EAP-PEAP/MSCHAPv2 with RADIUS servers that use old peaplabel
+   (e.g., Funk Odyssey and SBR, Meetinghouse Aegis, Interlink RAD-Series)
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	eap=PEAP
+	identity="user@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	phase1="peaplabel=0"
+	phase2="auth=MSCHAPV2"
+}
+
+
+3) EAP-TTLS/EAP-MD5-Challenge configuration with anonymous identity for the
+   unencrypted use. Real identity is sent only within an encrypted TLS tunnel.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP
+	eap=TTLS
+	identity="user@example.com"
+	anonymous_identity="anonymous@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	phase2="auth=MD5"
+}
+
+
+4) IEEE 802.1X (i.e., no WPA) with dynamic WEP keys (require both unicast and
+   broadcast); use EAP-TLS for authentication
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="1x-test"
+	scan_ssid=1
+	key_mgmt=IEEE8021X
+	eap=TLS
+	identity="user@example.com"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+	eapol_flags=3
+}
+
+
+5) Catch all example that allows more or less all configuration modes. The
+   configuration options are used based on what security policy is used in the
+   selected SSID. This is mostly for testing and is not recommended for normal
+   use.
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+network={
+	ssid="example"
+	scan_ssid=1
+	key_mgmt=WPA-EAP WPA-PSK IEEE8021X NONE
+	pairwise=CCMP TKIP
+	group=CCMP TKIP WEP104 WEP40
+	psk="very secret passphrase"
+	eap=TTLS PEAP TLS
+	identity="user@example.com"
+	password="foobar"
+	ca_cert="/etc/cert/ca.pem"
+	client_cert="/etc/cert/user.pem"
+	private_key="/etc/cert/user.prv"
+	private_key_passwd="password"
+	phase1="peaplabel=0"
+	ca_cert2="/etc/cert/ca2.pem"
+	client_cert2="/etc/cer/user.pem"
+	private_key2="/etc/cer/user.prv"
+	private_key2_passwd="password"
+}
+
+
+6) Authentication for wired Ethernet. This can be used with 'wired' or
+   'roboswitch' interface (-Dwired or -Droboswitch on command line).
+
+ctrl_interface=/var/run/wpa_supplicant
+ctrl_interface_group=wheel
+ap_scan=0
+network={
+	key_mgmt=IEEE8021X
+	eap=MD5
+	identity="user"
+	password="password"
+	eapol_flags=0
+}
+
+
+
+Certificates
+------------
+
+Some EAP authentication methods require use of certificates. EAP-TLS
+uses both server side and client certificates whereas EAP-PEAP and
+EAP-TTLS only require the server side certificate. When client
+certificate is used, a matching private key file has to also be
+included in configuration. If the private key uses a passphrase, this
+has to be configured in wpa_supplicant.conf ("private_key_passwd").
+
+wpa_supplicant supports X.509 certificates in PEM and DER
+formats. User certificate and private key can be included in the same
+file.
+
+If the user certificate and private key is received in PKCS#12/PFX
+format, they need to be converted to suitable PEM/DER format for
+wpa_supplicant. This can be done, e.g., with following commands:
+
+# convert client certificate and private key to PEM format
+openssl pkcs12 -in example.pfx -out user.pem -clcerts
+# convert CA certificate (if included in PFX file) to PEM format
+openssl pkcs12 -in example.pfx -out ca.pem -cacerts -nokeys
+
+
+
+wpa_cli
+-------
+
+wpa_cli is a text-based frontend program for interacting with
+wpa_supplicant. It is used to query current status, change
+configuration, trigger events, and request interactive user input.
+
+wpa_cli can show the current authentication status, selected security
+mode, dot11 and dot1x MIBs, etc. In addition, it can configure some
+variables like EAPOL state machine parameters and trigger events like
+reassociation and IEEE 802.1X logoff/logon. wpa_cli provides a user
+interface to request authentication information, like username and
+password, if these are not included in the configuration. This can be
+used to implement, e.g., one-time-passwords or generic token card
+authentication where the authentication is based on a
+challenge-response that uses an external device for generating the
+response.
+
+The control interface of wpa_supplicant can be configured to allow
+non-root user access (ctrl_interface_group in the configuration
+file). This makes it possible to run wpa_cli with a normal user
+account.
+
+wpa_cli supports two modes: interactive and command line. Both modes
+share the same command set and the main difference is in interactive
+mode providing access to unsolicited messages (event messages,
+username/password requests).
+
+Interactive mode is started when wpa_cli is executed without including
+the command as a command line parameter. Commands are then entered on
+the wpa_cli prompt. In command line mode, the same commands are
+entered as command line arguments for wpa_cli.
+
+
+Interactive authentication parameters request
+
+When wpa_supplicant need authentication parameters, like username and
+password, which are not present in the configuration file, it sends a
+request message to all attached frontend programs, e.g., wpa_cli in
+interactive mode. wpa_cli shows these requests with
+"CTRL-REQ-<type>-<id>:<text>" prefix. <type> is IDENTITY, PASSWORD, or
+OTP (one-time-password). <id> is a unique identifier for the current
+network. <text> is description of the request. In case of OTP request,
+it includes the challenge from the authentication server.
+
+The reply to these requests can be given with 'identity', 'password',
+and 'otp' commands. <id> needs to be copied from the the matching
+request. 'password' and 'otp' commands can be used regardless of
+whether the request was for PASSWORD or OTP. The main difference
+between these two commands is that values given with 'password' are
+remembered as long as wpa_supplicant is running whereas values given
+with 'otp' are used only once and then forgotten, i.e., wpa_supplicant
+will ask frontend for a new value for every use. This can be used to
+implement one-time-password lists and generic token card -based
+authentication.
+
+Example request for password and a matching reply:
+
+CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
+> password 1 mysecretpassword
+
+Example request for generic token card challenge-response:
+
+CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar

+
+
+Using wpa_cli to run external program on connect/disconnect
+-----------------------------------------------------------
+
+wpa_cli can used to run external programs whenever wpa_supplicant
+connects or disconnects from a network. This can be used, e.g., to
+update network configuration and/or trigget DHCP client to update IP
+addresses, etc.
+
+One wpa_cli process in "action" mode needs to be started for each
+interface. For example, the following command starts wpa_cli for the
+default ingterface (-i can be used to select the interface in case of
+more than one interface being used at the same time):
+
+wpa_cli -a/sbin/wpa_action.sh -B
+
+The action file (-a option, /sbin/wpa_action.sh in this example) will
+be executed whenever wpa_supplicant completes authentication (connect
+event) or detects disconnection). The action script will be called
+with two command line arguments: interface name and event (CONNECTED
+or DISCONNECTED). If the action script needs to get more information
+about the current network, it can use 'wpa_cli status' to query
+wpa_supplicant for more information.
+
+Following example can be used as a simple template for an action
+script:
+
+#!/bin/sh
+
+IFNAME=$1
+CMD=$2
+
+if [ "$CMD" = "CONNECTED" ]; then
+    SSID=`wpa_cli -i$IFNAME status | grep ^ssid= | cut -f2- -d=`
+    # configure network, signal DHCP client, etc.
+fi
+
+if [ "$CMD" = "DISCONNECTED" ]; then
+    # remove network configuration, if needed
+    SSID=
+fi
+
+
+
+Integrating with pcmcia-cs/cardmgr scripts
+------------------------------------------
+
+wpa_supplicant needs to be running when using a wireless network with
+WPA. It can be started either from system startup scripts or from
+pcmcia-cs/cardmgr scripts (when using PC Cards). WPA handshake must be
+completed before data frames can be exchanged, so wpa_supplicant
+should be started before DHCP client.
+
+For example, following small changes to pcmcia-cs scripts can be used
+to enable WPA support:
+
+Add MODE="Managed" and WPA="y" to the network scheme in
+/etc/pcmcia/wireless.opts.
+
+Add the following block to the end of 'start' action handler in
+/etc/pcmcia/wireless:
+
+    if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+	/usr/local/bin/wpa_supplicant -B -c/etc/wpa_supplicant.conf \
+		-i$DEVICE
+    fi
+
+Add the following block to the end of 'stop' action handler (may need
+to be separated from other actions) in /etc/pcmcia/wireless:
+
+    if [ "$WPA" = "y" -a -x /usr/local/bin/wpa_supplicant ]; then
+	killall wpa_supplicant
+    fi
+
+This will make cardmgr start wpa_supplicant when the card is plugged
+in.
+
+
+
+Dynamic interface add and operation without configuration files
+---------------------------------------------------------------
+
+wpa_supplicant can be started without any configuration files or
+network interfaces. When used in this way, a global (i.e., per
+wpa_supplicant process) control interface is used to add and remove
+network interfaces. Each network interface can then be configured
+through a per-network interface control interface. For example,
+following commands show how to start wpa_supplicant without any
+network interfaces and then add a network interface and configure a
+network (SSID):
+
+# Start wpa_supplicant in the background
+wpa_supplicant -g/var/run/wpa_supplicant-global -B
+
+# Add a new interface (wlan0, no configuration file, driver=wext, and
+# enable control interface)
+wpa_cli -g/var/run/wpa_supplicant-global interface_add wlan0 \
+	"" wext /var/run/wpa_supplicant
+
+# Configure a network using the newly added network interface:
+wpa_cli -iwlan0 add_network
+wpa_cli -iwlan0 set_network 0 ssid '"test"'
+wpa_cli -iwlan0 set_network 0 key_mgmt WPA-PSK
+wpa_cli -iwlan0 set_network 0 psk '"12345678"'
+wpa_cli -iwlan0 set_network 0 pairwise TKIP
+wpa_cli -iwlan0 set_network 0 group TKIP
+wpa_cli -iwlan0 set_network 0 proto WPA
+wpa_cli -iwlan0 enable_network 0
+
+# At this point, the new network interface should start trying to associate
+# with the WPA-PSK network using SSID test.
+
+# Remove network interface
+wpa_cli -g/var/run/wpa_supplicant-global interface_remove wlan0
+
+
+Privilege separation
+--------------------
+
+To minimize the size of code that needs to be run with root privileges
+(e.g., to control wireless interface operation), wpa_supplicant
+supports optional privilege separation. If enabled, this separates the
+privileged operations into a separate process (wpa_priv) while leaving
+rest of the code (e.g., EAP authentication and WPA handshakes) into an
+unprivileged process (wpa_supplicant) that can be run as non-root
+user. Privilege separation restricts the effects of potential software
+errors by containing the majority of the code in an unprivileged
+process to avoid full system compromise.
+
+Privilege separation is not enabled by default and it can be enabled
+by adding CONFIG_PRIVSEP=y to the build configuration (.config). When
+enabled, the privileged operations (driver wrapper and l2_packet) are
+linked into a separate daemon program, wpa_priv. The unprivileged
+program, wpa_supplicant, will be built with a special driver/l2_packet
+wrappers that communicate with the privileged wpa_priv process to
+perform the needed operations. wpa_priv can control what privileged
+are allowed.
+
+wpa_priv needs to be run with network admin privileges (usually, root
+user). It opens a UNIX domain socket for each interface that is
+included on the command line; any other interface will be off limits
+for wpa_supplicant in this kind of configuration. After this,
+wpa_supplicant can be run as a non-root user (e.g., all standard users
+on a laptop or as a special non-privileged user account created just
+for this purpose to limit access to user files even further).
+
+
+Example configuration:
+- create user group for users that are allowed to use wpa_supplicant
+  ('wpapriv' in this example) and assign users that should be able to
+  use wpa_supplicant into that group
+- create /var/run/wpa_priv directory for UNIX domain sockets and control
+  user access by setting it accessible only for the wpapriv group:
+  mkdir /var/run/wpa_priv
+  chown root:wpapriv /var/run/wpa_priv
+  chmod 0750 /var/run/wpa_priv
+- start wpa_priv as root (e.g., from system startup scripts) with the
+  enabled interfaces configured on the command line:
+  wpa_priv -B -P /var/run/wpa_priv.pid wext:ath0
+- run wpa_supplicant as non-root with a user that is in wpapriv group:
+  wpa_supplicant -i ath0 -c wpa_supplicant.conf
+
+wpa_priv does not use the network interface before wpa_supplicant is
+started, so it is fine to include network interfaces that are not
+available at the time wpa_priv is started. As an alternative, wpa_priv
+can be started when an interface is added (hotplug/udev/etc. scripts).
+wpa_priv can control multiple interface with one process, but it is
+also possible to run multiple wpa_priv processes at the same time, if
+desired.

+wpa_supplicant and Hotspot 2.0
+==============================
+
+This document describe how the IEEE 802.11u Interworking and Wi-Fi
+Hotspot 2.0 (Release 1) implementation in wpa_supplicant can be
+configured and how an external component on the client e.g., management
+GUI or Wi-Fi framework) is used to manage this functionality.
+
+
+Introduction to Wi-Fi Hotspot 2.0
+---------------------------------
+
+Hotspot 2.0 is the name of the Wi-Fi Alliance specification that is used
+in the Wi-Fi CERTIFIED Passpoint<TM> program. More information about
+this is available in this white paper:
+
+http://www.wi-fi.org/knowledge-center/white-papers/wi-fi-certified-passpoint%E2%84%A2-new-program-wi-fi-alliance%C2%AE-enable-seamless
+
+The Hotspot 2.0 specification is also available from WFA:
+https://www.wi-fi.org/knowledge-center/published-specifications
+
+The core Interworking functionality (network selection, GAS/ANQP) were
+standardized in IEEE Std 802.11u-2011 which is now part of the IEEE Std
+802.11-2012.
+
+
+wpa_supplicant network selection
+--------------------------------
+
+Interworking support added option for configuring credentials that can
+work with multiple networks as an alternative to configuration of
+network blocks (e.g., per-SSID parameters). When requested to perform
+network selection, wpa_supplicant picks the highest priority enabled
+network block or credential. If a credential is picked (based on ANQP
+information from APs), a temporary network block is created
+automatically for the matching network. This temporary network block is
+used similarly to the network blocks that can be configured by the user,
+but it is not stored into the configuration file and is meant to be used
+only for temporary period of time since a new one can be created
+whenever needed based on ANQP information and the credential.
+
+By default, wpa_supplicant is not using automatic network selection
+unless requested explicitly with the interworking_select command. This
+can be changed with the auto_interworking=1 parameter to perform network
+selection automatically whenever trying to find a network for connection
+and none of the enabled network blocks match with the scan results. This
+case works similarly to "interworking_select auto", i.e., wpa_supplicant
+will internally determine which network or credential is going to be
+used based on configured priorities, scan results, and ANQP information.
+
+
+wpa_supplicant configuration
+----------------------------
+
+Interworking and Hotspot 2.0 functionality are optional components that
+need to be enabled in the wpa_supplicant build configuration
+(.config). This is done by adding following parameters into that file:
+
+CONFIG_INTERWORKING=y
+CONFIG_HS20=y
+
+It should be noted that this functionality requires a driver that
+supports GAS/ANQP operations. This uses the same design as P2P, i.e.,
+Action frame processing and building in user space within
+wpa_supplicant. The Linux nl80211 driver interface provides the needed
+functionality for this.
+
+
+There are number of run-time configuration parameters (e.g., in
+wpa_supplicant.conf when using the configuration file) that can be used
+to control Hotspot 2.0 operations.
+
+# Enable Interworking
+interworking=1
+
+# Enable Hotspot 2.0
+hs20=1
+
+# Parameters for controlling scanning
+
+# Homogenous ESS identifier
+# If this is set, scans will be used to request response only from BSSes
+# belonging to the specified Homogeneous ESS. This is used only if interworking
+# is enabled.
+#hessid=00:11:22:33:44:55
+
+# Access Network Type
+# When Interworking is enabled, scans can be limited to APs that advertise the
+# specified Access Network Type (0..15; with 15 indicating wildcard match).
+# This value controls the Access Network Type value in Probe Request frames.
+#access_network_type=15
+
+# Automatic network selection behavior
+# 0 = do not automatically go through Interworking network selection
+#     (i.e., require explicit interworking_select command for this; default)
+# 1 = perform Interworking network selection if one or more
+#     credentials have been configured and scan did not find a
+#     matching network block
+#auto_interworking=0
+
+
+Credentials can be pre-configured for automatic network selection:
+
+# credential block
+#
+# Each credential used for automatic network selection is configured as a set
+# of parameters that are compared to the information advertised by the APs when
+# interworking_select and interworking_connect commands are used.
+#
+# credential fields:
+#
+# priority: Priority group
+#	By default, all networks and credentials get the same priority group
+#	(0). This field can be used to give higher priority for credentials
+#	(and similarly in struct wpa_ssid for network blocks) to change the
+#	Interworking automatic networking selection behavior. The matching
+#	network (based on either an enabled network block or a credential)
+#	with the highest priority value will be selected.
+#
+# pcsc: Use PC/SC and SIM/USIM card
+#
+# realm: Home Realm for Interworking
+#
+# username: Username for Interworking network selection
+#
+# password: Password for Interworking network selection
+#
+# ca_cert: CA certificate for Interworking network selection
+#
+# client_cert: File path to client certificate file (PEM/DER)
+#	This field is used with Interworking networking selection for a case
+#	where client certificate/private key is used for authentication
+#	(EAP-TLS). Full path to the file should be used since working
+#	directory may change when wpa_supplicant is run in the background.
+#
+#	Alternatively, a named configuration blob can be used by setting
+#	this to blob://blob_name.
+#
+# private_key: File path to client private key file (PEM/DER/PFX)
+#	When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
+#	commented out. Both the private key and certificate will be read
+#	from the PKCS#12 file in this case. Full path to the file should be
+#	used since working directory may change when wpa_supplicant is run
+#	in the background.
+#
+#	Windows certificate store can be used by leaving client_cert out and
+#	configuring private_key in one of the following formats:
+#
+#	cert://substring_to_match
+#
+#	hash://certificate_thumbprint_in_hex
+#
+#	For example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
+#
+#	Note that when running wpa_supplicant as an application, the user
+#	certificate store (My user account) is used, whereas computer store
+#	(Computer account) is used when running wpasvc as a service.
+#
+#	Alternatively, a named configuration blob can be used by setting
+#	this to blob://blob_name.
+#
+# private_key_passwd: Password for private key file
+#
+# imsi: IMSI in <MCC> | <MNC> | '-' | <MSIN> format
+#
+# milenage: Milenage parameters for SIM/USIM simulator in <Ki>:<OPc>:<SQN>
+#	format
+#
+# domain: Home service provider FQDN
+#	This is used to compare against the Domain Name List to figure out
+#	whether the AP is operated by the Home SP.
+#
+# roaming_consortium: Roaming Consortium OI
+#	If roaming_consortium_len is non-zero, this field contains the
+#	Roaming Consortium OI that can be used to determine which access
+#	points support authentication with this credential. This is an
+#	alternative to the use of the realm parameter. When using Roaming
+#	Consortium to match the network, the EAP parameters need to be
+#	pre-configured with the credential since the NAI Realm information
+#	may not be available or fetched.
+#
+# eap: Pre-configured EAP method
+#	This optional field can be used to specify which EAP method will be

+#	This optional field is used with like the 'eap' parameter.
+#
+# excluded_ssid: Excluded SSID
+#	This optional field can be used to excluded specific SSID(s) from

+
+Control interface
+-----------------
+
+wpa_supplicant provides a control interface that can be used from
+external programs to manage various operations. The included command
+line tool, wpa_cli, can be used for manual testing with this interface.
+
+Following wpa_cli interactive mode commands show some examples of manual
+operations related to Hotspot 2.0:
+
+Remove configured networks and credentials:
+
+> remove_network all
+OK
+> remove_cred all
+OK
+
+
+Add a username/password credential:
+
+> add_cred
+0
+> set_cred 0 realm "mail.example.com"
+OK
+> set_cred 0 username "username"
+OK
+> set_cred 0 password "password"
+OK
+> set_cred 0 priority 1
+OK
+
+Add a SIM credential using a simulated SIM/USIM card for testing:
+
+> add_cred
+1
+> set_cred 1 imsi "23456-0000000000"
+OK
+> set_cred 1 milenage "90dca4eda45b53cf0f12d7c9c3bc6a89:cb9cccc4b9258e6dca4760379fb82581:000000000123"
+OK
+> set_cred 1 priority 1
+OK
+
+Note: the return value of add_cred is used as the first argument to
+the following set_cred commands.
+
+
+Add a WPA2-Enterprise network:
+
+> add_network
+0
+> set_network 0 key_mgmt WPA-EAP
+OK
+> set_network 0 ssid "enterprise"
+OK
+> set_network 0 eap TTLS
+OK
+> set_network 0 anonymous_identity "anonymous"
+OK
+> set_network 0 identity "user"
+OK
+> set_network 0 password "password"
+OK
+> set_network 0 priority 0
+OK
+> enable_network 0 no-connect
+OK
+
+
+Add an open network:
+
+> add_network
+3
+> set_network 3 key_mgmt NONE
+OK
+> set_network 3 ssid "coffee-shop"
+OK
+> select_network 3
+OK
+
+Note: the return value of add_network is used as the first argument to
+the following set_network commands.
+
+The preferred credentials/networks can be indicated with the priority
+parameter (1 is higher priority than 0).
+
+
+Interworking network selection can be started with interworking_select
+command. This instructs wpa_supplicant to run a network scan and iterate
+through the discovered APs to request ANQP information from the APs that
+advertise support for Interworking/Hotspot 2.0:
+
+> interworking_select
+OK

+
+
+INTERWORKING-AP event messages indicate the APs that support network
+selection and for which there is a matching
+credential. interworking_connect command can be used to select a network
+to connect with:
+
+
+> interworking_connect 02:00:00:00:01:00

+<3>CTRL-EVENT-CONNECTED - Connection to 02:00:00:00:01:00 completed (auth) [id=0 id_str=]
+
+
+wpa_supplicant creates a temporary network block for the selected
+network based on the configured credential and ANQP information from the
+AP:
+
+> list_networks
+network id / ssid / bssid / flags
+0	Example Network	any	[CURRENT]
+> get_network 0 key_mgmt
+WPA-EAP
+> get_network 0 eap
+TTLS
+
+
+Alternatively to using an external program to select the network,
+"interworking_select auto" command can be used to request wpa_supplicant
+to select which network to use based on configured priorities:
+
+
+> remove_network all
+OK

+wpa_supplicant and Wi-Fi P2P
+============================
+
+This document describes how the Wi-Fi P2P implementation in
+wpa_supplicant can be configured and how an external component on the
+client (e.g., management GUI) is used to enable WPS enrollment and
+registrar registration.
+
+
+Introduction to Wi-Fi P2P
+-------------------------
+
+TODO
+
+More information about Wi-Fi P2P is available from Wi-Fi Alliance:
+http://www.wi-fi.org/Wi-Fi_Direct.php
+
+
+wpa_supplicant implementation
+-----------------------------
+
+TODO
+
+
+wpa_supplicant configuration
+----------------------------
+
+Wi-Fi P2P is an optional component that needs to be enabled in the
+wpa_supplicant build configuration (.config). Here is an example
+configuration that includes Wi-Fi P2P support and Linux nl80211
+-based driver interface:
+
+CONFIG_DRIVER_NL80211=y
+CONFIG_CTRL_IFACE=y
+CONFIG_P2P=y
+CONFIG_AP=y
+CONFIG_WPS=y
+
+
+In run-time configuration file (wpa_supplicant.conf), some parameters
+for P2P may be set. In order to make the devices easier to recognize,
+device_name and device_type should be specified. For example,
+something like this should be included:
+
+ctrl_interface=/var/run/wpa_supplicant
+device_name=My P2P Device
+device_type=1-0050F204-1
+
+
+wpa_cli
+-------
+
+Actual Wi-Fi P2P operations are requested during runtime. These can be
+done for example using wpa_cli (which is described below) or a GUI
+like wpa_gui-qt4.
+
+
+wpa_cli starts in interactive mode if no command string is included on
+the command line. By default, it will select the first network interface
+that it can find (and that wpa_supplicant controls). If more than one
+interface is in use, it may be necessary to select one of the explicitly
+by adding -i argument on the command line (e.g., 'wpa_cli -i wlan1').
+
+Most of the P2P operations are done on the main interface (e.g., the
+interface that is automatically added when the driver is loaded, e.g.,
+wlan0). When using a separate virtual interface for group operations
+(e.g., wlan1), the control interface for that group interface may need
+to be used for some operations (mainly WPS activation in GO). This may
+change in the future so that all the needed operations could be done
+over the main control interface.
+
+Device Discovery
+
+p2p_find [timeout in seconds] [type=<social|progressive>] \
+	[dev_id=<addr>] [delay=<search delay in ms>]
+
+The default behavior is to run a single full scan in the beginning and
+then scan only social channels. type=social will scan only social
+channels, i.e., it skips the initial full scan. type=progressive is
+like the default behavior, but it will scan through all the channels
+progressively one channel at the time in the Search state rounds. This
+will help in finding new groups or groups missed during the initial
+full scan.
+
+The optional dev_id option can be used to specify a single P2P peer to
+search for. The optional delay parameter can be used to request an extra
+delay to be used between search iterations (e.g., to free up radio
+resources for concurrent operations).
+
+p2p_listen [timeout in seconds]
+
+Start Listen-only state (become discoverable without searching for
+other devices). Optional parameter can be used to specify the duration
+for the Listen operation in seconds. This command may not be of that
+much use during normal operations and is mainly designed for
+testing. It can also be used to keep the device discoverable without
+having to maintain a group.
+
+p2p_stop_find
+
+Stop ongoing P2P device discovery or other operation (connect, listen
+mode).
+
+p2p_flush
+
+Flush P2P peer table and state.
+
+Group Formation
+
+p2p_prov_disc <peer device address> <display|keypad|pbc> [join|auto]
+
+Send P2P provision discovery request to the specified peer. The
+parameters for this command are the P2P device address of the peer and
+the desired configuration method. For example, "p2p_prov_disc
+02:01:02:03:04:05 display" would request the peer to display a PIN for
+us and "p2p_prov_disc 02:01:02:03:04:05 keypad" would request the peer
+to enter a PIN that we display.
+
+The optional "join" parameter can be used to indicate that this command
+is requesting an already running GO to prepare for a new client. This is
+mainly used with "display" to request it to display a PIN. The "auto"
+parameter can be used to request wpa_supplicant to automatically figure
+out whether the peer device is operating as a GO and if so, use
+join-a-group style PD instead of GO Negotiation style PD.
+
+p2p_connect <peer device address> <pbc|pin|PIN#> [display|keypad]
+	[persistent|persistent=<network id>] [join|auth]
+	[go_intent=<0..15>] [freq=<in MHz>] [ht40] [provdisc]
+
+Start P2P group formation with a discovered P2P peer. This includes
+optional group owner negotiation, group interface setup, provisioning,
+and establishing data connection.
+
+The <pbc|pin|PIN#> parameter specifies the WPS provisioning
+method. "pbc" string starts pushbutton method, "pin" string start PIN
+method using an automatically generated PIN (which will be returned as
+the command return code), PIN# means that a pre-selected PIN can be
+used (e.g., 12345670). [display|keypad] is used with PIN method
+to specify which PIN is used (display=dynamically generated random PIN
+from local display, keypad=PIN entered from peer display). "persistent"
+parameter can be used to request a persistent group to be formed. The
+"persistent=<network id>" alternative can be used to pre-populate
+SSID/passphrase configuration based on a previously used persistent
+group where this device was the GO. The previously used parameters will
+then be used if the local end becomes the GO in GO Negotiation (which
+can be forced with go_intent=15).
+
+"join" indicates that this is a command to join an existing group as a
+client. It skips the GO Negotiation part. This will send a Provision
+Discovery Request message to the target GO before associating for WPS
+provisioning.
+
+"auth" indicates that the WPS parameters are authorized for the peer
+device without actually starting GO Negotiation (i.e., the peer is
+expected to initiate GO Negotiation). This is mainly for testing
+purposes.
+
+"go_intent" can be used to override the default GO Intent for this GO
+Negotiation.
+
+"freq" can be used to set a forced operating channel (e.g., freq=2412
+to select 2.4 GHz channel 1).
+
+"provdisc" can be used to request a Provision Discovery exchange to be
+used prior to starting GO Negotiation as a workaround with some deployed
+P2P implementations that require this to allow the user to accept the
+connection.
+
+p2p_group_add [persistent|persistent=<network id>] [freq=<freq in MHz>] [ht40]
+
+Set up a P2P group owner manually (i.e., without group owner
+negotiation with a specific peer). This is also known as autonomous
+GO. Optional persistent=<network id> can be used to specify restart of
+a persistent group. Optional freq=<freq in MHz> can be used to force
+the GO to be started on a specific frequency. Special freq=2 or freq=5
+options can be used to request the best 2.4 GHz or 5 GHz band channel
+to be selected automatically.
+
+p2p_reject <peer device address>
+
+Reject connection attempt from a peer (specified with a device
+address). This is a mechanism to reject a pending GO Negotiation with
+a peer and request to automatically block any further connection or
+discovery of the peer.
+
+p2p_group_remove <group interface>
+
+Terminate a P2P group. If a new virtual network interface was used for
+the group, it will also be removed. The network interface name of the
+group interface is used as a parameter for this command.
+
+p2p_cancel
+
+Cancel an ongoing P2P group formation and joining-a-group related
+operation. This operations unauthorizes the specific peer device (if any
+had been authorized to start group formation), stops P2P find (if in
+progress), stops pending operations for join-a-group, and removes the
+P2P group interface (if one was used) that is in the WPS provisioning
+step. If the WPS provisioning step has been completed, the group is not
+terminated.
+
+Service Discovery
+
+p2p_serv_disc_req
+
+Schedule a P2P service discovery request. The parameters for this
+command are the device address of the peer device (or 00:00:00:00:00:00
+for wildcard query that is sent to every discovered P2P peer that
+supports service discovery) and P2P Service Query TLV(s) as hexdump. For
+example,
+
+p2p_serv_disc_req 00:00:00:00:00:00 02000001
+
+schedules a request for listing all available services of all service
+discovery protocols and requests this to be sent to all discovered
+peers (note: this can result in long response frames). The pending
+requests are sent during device discovery (see p2p_find).
+
+Only a single pending wildcard query is supported, but there can be
+multiple pending peer device specific queries (each will be sent in
+sequence whenever the peer is found).
+
+This command returns an identifier for the pending query (e.g.,
+"1f77628") that can be used to cancel the request. Directed requests
+will be automatically removed when the specified peer has replied to
+it.
+
+For UPnP, an alternative command format can be used to specify a
+single query TLV (i.e., a service discovery for a specific UPnP
+service):
+
+p2p_serv_disc_req 00:00:00:00:00:00 upnp <version hex> <ST: from M-SEARCH>
+
+For example:
+
+p2p_serv_disc_req 00:00:00:00:00:00 upnp 10 urn:schemas-upnp-org:device:InternetGatewayDevice:1

+p2p_serv_disc_resp
+
+Reply to a service discovery query. This command takes following
+parameters: frequency in MHz, destination address, dialog token,
+response TLV(s). The first three parameters are copied from the
+request event. For example, "p2p_serv_disc_resp 2437 02:40:61:c2:f3:b7
+1 0300000101". This command is used only if external program is used
+to process the request (see p2p_serv_disc_external).
+
+p2p_service_update
+
+Indicate that local services have changed. This is used to increment
+the P2P service indicator value so that peers know when previously
+cached information may have changed. This is only needed when external
+service discovery processing is enabled since the commands to
+pre-configure services for internal processing will increment the
+indicator automatically.
+
+p2p_serv_disc_external <0|1>
+
+Configure external processing of P2P service requests: 0 (default) =
+no external processing of requests (i.e., internal code will process
+each request based on pre-configured services), 1 = external
+processing of requests (external program is responsible for replying
+to service discovery requests with p2p_serv_disc_resp). Please note
+that there is quite strict limit on how quickly the response needs to
+be transmitted, so use of the internal processing is strongly
+recommended.
+
+p2p_service_add bonjour <query hexdump> <RDATA hexdump>
+
+Add a local Bonjour service for internal SD query processing.

+
+Invitation
+
+p2p_invite [persistent=<network id>|group=<group ifname>] [peer=address]
+	[go_dev_addr=address] [freq=<freq in MHz>] [ht40]
+
+Invite a peer to join a group (e.g., group=wlan1) or to reinvoke a
+persistent group (e.g., persistent=4). If the peer device is the GO of
+the persistent group, the peer parameter is not needed. Otherwise it is
+used to specify which device to invite. go_dev_addr parameter can be
+used to override the GO device address for Invitation Request should
+it be not known for some reason (this should not be needed in most
+cases). When reinvoking a persistent group, the GO device can specify
+the frequency for the group with the freq parameter.
+
+Group Operations
+
+(These are used on the group interface.)
+
+wps_pin <any|address> <PIN>
+
+Start WPS PIN method. This allows a single WPS Enrollee to connect to
+the AP/GO. This is used on the GO when a P2P client joins an existing
+group. The second parameter is the address of the Enrollee or a string
+"any" to allow any station to use the entered PIN (which will restrict
+the PIN for one-time-use). PIN is the Enrollee PIN read either from a
+label or display on the P2P Client/WPS Enrollee.
+
+wps_pbc
+
+Start WPS PBC method (i.e., push the button). This allows a single WPS
+Enrollee to connect to the AP/GO. This is used on the GO when a P2P
+client joins an existing group.
+
+p2p_get_passphrase
+
+Get the passphrase for a group (only available when acting as a GO).
+
+p2p_presence_req [<duration> <interval>] [<duration> <interval>]
+
+Send a P2P Presence Request to the GO (this is only available when
+acting as a P2P client). If no duration/interval pairs are given, the
+request indicates that this client has no special needs for GO
+presence. the first parameter pair gives the preferred duration and
+interval values in microseconds. If the second pair is included, that
+indicates which value would be acceptable.
+
+Parameters
+
+p2p_ext_listen [<period> <interval>]
+
+Configure Extended Listen Timing. If the parameters are omitted, this
+feature is disabled. If the parameters are included, Listen State will
+be entered every interval msec for at least period msec. Both values
+have acceptable range of 1-65535 (with interval obviously having to be
+larger than or equal to duration). If the P2P module is not idle at
+the time the Extended Listen Timing timeout occurs, the Listen State
+operation will be skipped.
+
+The configured values will also be advertised to other P2P Devices. The
+received values are available in the p2p_peer command output:
+
+ext_listen_period=100 ext_listen_interval=5000
+
+p2p_set <field> <value>
+
+Change dynamic P2P parameters
+
+p2p_set discoverability <0/1>
+
+Disable/enable advertisement of client discoverability. This is
+enabled by default and this parameter is mainly used to allow testing
+of device discoverability.
+
+p2p_set managed <0/1>
+
+Disable/enable managed P2P Device operations. This is disabled by
+default.
+
+p2p_set listen_channel <1/6/11>
+
+Set P2P Listen channel. This is mainly meant for testing purposes and
+changing the Listen channel during normal operations can result in
+protocol failures.
+
+p2p_set ssid_postfix <postfix>
+
+Set postfix string to be added to the automatically generated P2P SSID
+(DIRECT-<two random characters>). For example, postfix of "-testing"
+could result in the SSID becoming DIRECT-ab-testing.
+
+set <field> <value>
+
+Set global configuration parameters which may also affect P2P
+operations. The format on these parameters is same as is used in
+wpa_supplicant.conf. Only the parameters listen here should be
+changed. Modifying other parameters may result in incorrect behavior
+since not all existing users of the parameters are updated.
+
+set uuid <UUID>
+
+Set WPS UUID (by default, this is generated based on the MAC address).
+
+set device_name <device name>
+
+Set WPS Device Name (also included in some P2P messages).

+
+Set P2P SSID postfix.
+
+set persistent_reconnect <0/1>

+
+Set country code (this is included in some P2P messages).
+
+Status
+
+p2p_peers [discovered]

+wpa_supplicant and Wi-Fi Protected Setup (WPS)
+==============================================
+
+This document describes how the WPS implementation in wpa_supplicant
+can be configured and how an external component on the client (e.g.,
+management GUI) is used to enable WPS enrollment and registrar
+registration.
+
+
+Introduction to WPS
+-------------------
+
+Wi-Fi Protected Setup (WPS) is a mechanism for easy configuration of a
+wireless network. It allows automated generation of random keys (WPA
+passphrase/PSK) and configuration of an access point and client
+devices. WPS includes number of methods for setting up connections
+with PIN method and push-button configuration (PBC) being the most
+commonly deployed options.
+
+While WPS can enable more home networks to use encryption in the
+wireless network, it should be noted that the use of the PIN and
+especially PBC mechanisms for authenticating the initial key setup is
+not very secure. As such, use of WPS may not be suitable for
+environments that require secure network access without chance for
+allowing outsiders to gain access during the setup phase.
+
+WPS uses following terms to describe the entities participating in the
+network setup:
+- access point: the WLAN access point
+- Registrar: a device that control a network and can authorize
+  addition of new devices); this may be either in the AP ("internal
+  Registrar") or in an external device, e.g., a laptop, ("external
+  Registrar")
+- Enrollee: a device that is being authorized to use the network
+
+It should also be noted that the AP and a client device may change
+roles (i.e., AP acts as an Enrollee and client device as a Registrar)
+when WPS is used to configure the access point.
+
+
+More information about WPS is available from Wi-Fi Alliance:
+http://www.wi-fi.org/wifi-protected-setup
+
+
+wpa_supplicant implementation
+-----------------------------
+
+wpa_supplicant includes an optional WPS component that can be used as
+an Enrollee to enroll new network credential or as a Registrar to
+configure an AP.
+
+
+wpa_supplicant configuration
+----------------------------
+
+WPS is an optional component that needs to be enabled in
+wpa_supplicant build configuration (.config). Here is an example
+configuration that includes WPS support and Linux nl80211 -based
+driver interface:
+
+CONFIG_DRIVER_NL80211=y
+CONFIG_WPS=y
+CONFIG_WPS2=y
+
+If you want to enable WPS external registrar (ER) functionality, you
+will also need to add following line:
+
+CONFIG_WPS_ER=y
+
+Following parameter can be used to enable support for NFC config method:
+
+CONFIG_WPS_NFC=y
+
+
+WPS needs the Universally Unique IDentifier (UUID; see RFC 4122) for
+the device. This is configured in the runtime configuration for
+wpa_supplicant (if not set, UUID will be generated based on local MAC
+address):
+
+# example UUID for WPS
+uuid=12345678-9abc-def0-1234-56789abcdef0
+
+The network configuration blocks needed for WPS are added
+automatically based on control interface commands, so they do not need
+to be added explicitly in the configuration file.
+
+WPS registration will generate new network blocks for the acquired
+credentials. If these are to be stored for future use (after
+restarting wpa_supplicant), wpa_supplicant will need to be configured
+to allow configuration file updates:
+
+update_config=1
+
+
+
+External operations
+-------------------
+
+WPS requires either a device PIN code (usually, 8-digit number) or a
+pushbutton event (for PBC) to allow a new WPS Enrollee to join the
+network. wpa_supplicant uses the control interface as an input channel
+for these events.
+
+The PIN value used in the commands must be processed by an UI to
+remove non-digit characters and potentially, to verify the checksum
+digit. "wpa_cli wps_check_pin <PIN>" can be used to do such processing.
+It returns FAIL if the PIN is invalid, or FAIL-CHECKSUM if the checksum
+digit is incorrect, or the processed PIN (non-digit characters removed)
+if the PIN is valid.
+
+If the client device has a display, a random PIN has to be generated
+for each WPS registration session. wpa_supplicant can do this with a
+control interface request, e.g., by calling wpa_cli:
+
+wpa_cli wps_pin any
+
+This will return the generated 8-digit PIN which will then need to be
+entered at the Registrar to complete WPS registration. At that point,
+the client will be enrolled with credentials needed to connect to the
+AP to access the network.
+
+
+If the client device does not have a display that could show the
+random PIN, a hardcoded PIN that is printed on a label can be
+used. wpa_supplicant is notified this with a control interface
+request, e.g., by calling wpa_cli:
+
+wpa_cli wps_pin any 12345670
+
+This starts the WPS negotiation in the same way as above with the
+generated PIN.
+
+When the wps_pin command is issued for an AP (including P2P GO) mode
+interface, an optional timeout parameter can be used to specify
+expiration timeout for the PIN in seconds. For example:
+
+wpa_cli wps_pin any 12345670 300
+
+
+If a random PIN is needed for a user interface, "wpa_cli wps_pin get"
+can be used to generate a new PIN without starting WPS negotiation.
+This random PIN can then be passed as an argument to another wps_pin
+call when the actual operation should be started.
+
+If the client design wants to support optional WPS PBC mode, this can
+be enabled by either a physical button in the client device or a
+virtual button in the user interface. The PBC operation requires that
+a button is also pressed at the AP/Registrar at about the same time (2
+minute window). wpa_supplicant is notified of the local button event
+over the control interface, e.g., by calling wpa_cli:
+
+wpa_cli wps_pbc
+
+At this point, the AP/Registrar has two minutes to complete WPS
+negotiation which will generate a new WPA PSK in the same way as the
+PIN method described above.
+
+
+If the client wants to operate in the Registrar role to learn the
+current AP configuration and optionally, to configure an AP,
+wpa_supplicant is notified over the control interface, e.g., with
+wpa_cli:
+
+wpa_cli wps_reg <AP BSSID> <AP PIN>
+(example: wpa_cli wps_reg 02:34:56:78:9a:bc 12345670)
+
+This is used to fetch the current AP settings instead of actually
+changing them. The main difference with the wps_pin command is that
+wps_reg uses the AP PIN (e.g., from a label on the AP) instead of a
+PIN generated at the client.
+
+In order to change the AP configuration, the new configuration
+parameters are given to the wps_reg command:
+
+wpa_cli wps_reg <AP BSSID> <AP PIN> <new SSID> <auth> <encr> <new key>
+examples:
+  wpa_cli wps_reg 02:34:56:78:9a:bc 12345670 testing WPA2PSK CCMP 12345678
+  wpa_cli wps_reg 02:34:56:78:9a:bc 12345670 clear OPEN NONE ""
+
+<auth> must be one of the following: OPEN WPAPSK WPA2PSK
+<encr> must be one of the following: NONE WEP TKIP CCMP
+
+
+Scanning
+--------
+
+Scan results ('wpa_cli scan_results' or 'wpa_cli bss <idx>') include a
+flags field that is used to indicate whether the BSS support WPS. If
+the AP support WPS, but has not recently activated a Registrar, [WPS]
+flag will be included. If PIN method has been recently selected,
+[WPS-PIN] is shown instead. Similarly, [WPS-PBC] is shown if PBC mode
+is in progress. GUI programs can use these as triggers for suggesting
+a guided WPS configuration to the user. In addition, control interface
+monitor events WPS-AP-AVAILABLE{,-PBC,-PIN} can be used to find out if
+there are WPS enabled APs in scan results without having to go through
+all the details in the GUI. These notification could be used, e.g., to
+suggest possible WPS connection to the user.
+
+
+wpa_gui
+-------
+
+wpa_gui-qt4 directory contains a sample GUI that shows an example of
+how WPS support can be integrated into the GUI. Its main window has a
+WPS tab that guides user through WPS registration with automatic AP
+selection. In addition, it shows how WPS can be started manually by
+selecting an AP from scan results.
+
+
+Credential processing
+---------------------
+
+By default, wpa_supplicant processes received credentials and updates
+its configuration internally. However, it is possible to
+control these operations from external programs, if desired.
+
+This internal processing can be disabled with wps_cred_processing=1
+option. When this is used, an external program is responsible for
+processing the credential attributes and updating wpa_supplicant
+configuration based on them.
+
+Following control interface messages are sent out for external programs:
+
+WPS-CRED-RECEIVED  <hexdump of Credential attribute(s)>
+For example:
+<2>WPS-CRED-RECEIVED 100e006f10260001011045000c6a6b6d2d7770732d74657374100300020020100f000200081027004030653462303435366332363666653064333961643135353461316634626637313234333761636664623766333939653534663166316230323061643434386235102000060266a0ee1727
+
+
+wpa_supplicant as WPS External Registrar (ER)
+---------------------------------------------
+
+wpa_supplicant can be used as a WPS ER to configure an AP or enroll
+new Enrollee to join the network. This functionality uses UPnP and
+requires that a working IP connectivity is available with the AP (this
+can be either over a wired or wireless connection).
+
+Separate wpa_supplicant process can be started for WPS ER
+operations. A special "none" driver can be used in such a case to
+indicate that no local network interface is actually controlled. For
+example, following command could be used to start the ER:
+
+wpa_supplicant -Dnone -c er.conf -ieth0
+
+Sample er.conf:
+
+ctrl_interface=DIR=/var/run/wpa_supplicant GROUP=admin
+device_name=WPS External Registrar
+
+
+wpa_cli commands for ER functionality:
+
+wps_er_start [IP address]
+- start WPS ER functionality
+- the optional IP address parameter can be used to filter operations only
+  to include a single AP
+- if run again while ER is active, the stored information (discovered APs
+  and Enrollees) are shown again
+
+wps_er_stop
+- stop WPS ER functionality
+
+wps_er_learn <UUID> <AP PIN>
+- learn AP configuration
+
+wps_er_set_config <UUID> <network id>
+- use AP configuration from a locally configured network (e.g., from
+  wps_reg command); this does not change the AP's configuration, but
+  only prepares a configuration to be used when enrolling a new device
+  to the AP
+
+wps_er_config <UUID> <AP PIN> <new SSID> <auth> <encr> <new key>
+- examples:
+  wps_er_config 87654321-9abc-def0-1234-56789abc0002 12345670 testing WPA2PSK CCMP 12345678
+  wpa_er_config 87654321-9abc-def0-1234-56789abc0002 12345670 clear OPEN NONE ""
+
+<auth> must be one of the following: OPEN WPAPSK WPA2PSK
+<encr> must be one of the following: NONE WEP TKIP CCMP
+
+
+wps_er_pbc <Enrollee UUID>
+- accept an Enrollee PBC using External Registrar
+
+wps_er_pin <Enrollee UUID> <PIN> [Enrollee MAC address]
+- add an Enrollee PIN to External Registrar
+- if Enrollee UUID is not known, "any" can be used to add a wildcard PIN
+- if the MAC address of the enrollee is known, it should be configured
+  to allow the AP to advertise list of authorized enrollees

+
+
+WPS with NFC
+------------
+
+WPS can be used with NFC-based configuration method. An NFC tag
+containing a password token from the Enrollee can be used to
+authenticate the connection instead of the PIN. In addition, an NFC tag
+with a configuration token can be used to transfer AP settings without
+going through the WPS protocol.
+
+When the station acts as an Enrollee, a local NFC tag with a password
+token can be used by touching the NFC interface of a Registrar.
+
+"wps_nfc [BSSID]" command starts WPS protocol run with the local end as
+the Enrollee using the NFC password token that is either pre-configured
+in the configuration file (wps_nfc_dev_pw_id, wps_nfc_dh_pubkey,
+wps_nfc_dh_privkey, wps_nfc_dev_pw) or generated dynamically with
+"wps_nfc_token <WPS|NDEF>" command. The included nfc_pw_token tool
+(build with "make nfc_pw_token") can be used to generate NFC password
+tokens during manufacturing (each station needs to have its own random
+keys).
+
+If the station includes NFC interface and reads an NFC tag with a MIME
+media type "application/vnd.wfa.wsc", the NDEF message payload (with or
+without NDEF encapsulation) can be delivered to wpa_supplicant using the
+following wpa_cli command:
+
+wps_nfc_tag_read <hexdump of payload>

+
+
+wpa_supplicant has support for being used as a WPA/WPA2/IEEE 802.1X
+Supplicant on Windows. The current port requires that WinPcap
+(http://winpcap.polito.it/) is installed for accessing packets and the
+driver interface. Both release versions 3.0 and 3.1 are supported.
+
+The current port is still somewhat experimental. It has been tested
+mainly on Windows XP (SP2) with limited set of NDIS drivers. In
+addition, the current version has been reported to work with Windows
+2000.
+
+All security modes have been verified to work (at least complete
+authentication and successfully ping a wired host):
+- plaintext
+- static WEP / open system authentication
+- static WEP / shared key authentication
+- IEEE 802.1X with dynamic WEP keys
+- WPA-PSK, TKIP, CCMP, TKIP+CCMP
+- WPA-EAP, TKIP, CCMP, TKIP+CCMP
+- WPA2-PSK, TKIP, CCMP, TKIP+CCMP

+
+
+Building wpa_supplicant with mingw
+----------------------------------
+
+The default build setup for wpa_supplicant is to use MinGW and
+cross-compiling from Linux to MinGW/Windows. It should also be
+possible to build this under Windows using the MinGW tools, but that
+is not tested nor supported and is likely to require some changes to
+the Makefile unless cygwin is used.
+
+
+Building wpa_supplicant with MSVC
+---------------------------------
+
+wpa_supplicant can be built with Microsoft Visual C++ compiler. This
+has been tested with Microsoft Visual C++ Toolkit 2003 and Visual
+Studio 2005 using the included nmake.mak as a Makefile for nmake. IDE
+can also be used by creating a project that includes the files and
+defines mentioned in nmake.mak. Example VS2005 solution and project
+files are included in vs2005 subdirectory. This can be used as a
+starting point for building the programs with VS2005 IDE. Visual Studio
+2008 Express Edition is also able to use these project files.
+
+WinPcap development package is needed for the build and this can be
+downloaded from http://www.winpcap.org/install/bin/WpdPack_4_0_2.zip. The
+default nmake.mak expects this to be unpacked into C:\dev\WpdPack so
+that Include and Lib directories are in this directory. The files can be
+stored elsewhere as long as the WINPCAPDIR in nmake.mak is updated to
+match with the selected directory. In case a project file in the IDE is
+used, these Include and Lib directories need to be added to project
+properties as additional include/library directories.
+
+OpenSSL source package can be downloaded from
+http://www.openssl.org/source/openssl-0.9.8i.tar.gz and built and
+installed following instructions in INSTALL.W32. Note that if EAP-FAST
+support will be included in the wpa_supplicant, OpenSSL needs to be
+patched to# support it openssl-0.9.8i-tls-extensions.patch. The example
+nmake.mak file expects OpenSSL to be installed into C:\dev\openssl, but
+this directory can be modified by changing OPENSSLDIR variable in
+nmake.mak.
+
+If you do not need EAP-FAST support, you may also be able to use Win32
+binary installation package of OpenSSL from
+http://www.slproweb.com/products/Win32OpenSSL.html instead of building
+the library yourself. In this case, you will need to copy Include and
+Lib directories in suitable directory, e.g., C:\dev\openssl for the
+default nmake.mak. Copy {Win32OpenSSLRoot}\include into
+C:\dev\openssl\include and make C:\dev\openssl\lib subdirectory with
+files from {Win32OpenSSLRoot}\VC (i.e., libeay*.lib and ssleay*.lib).
+This will end up using dynamically linked OpenSSL (i.e., .dll files are
+needed) for it. Alternative, you can copy files from
+{Win32OpenSSLRoot}\VC\static to create a static build (no OpenSSL .dll
+files needed).
+
+
+Building wpa_supplicant for cygwin
+----------------------------------
+
+wpa_supplicant can be built for cygwin by installing the needed
+development packages for cygwin. This includes things like compiler,
+make, openssl development package, etc. In addition, developer's pack
+for WinPcap (WPdpack.zip) from
+http://winpcap.polito.it/install/default.htm is needed.
+
+.config file should enable only one driver interface,
+CONFIG_DRIVER_NDIS. In addition, include directories may need to be
+added to match the system. An example configuration is available in
+defconfig. The library and include files for WinPcap will either need
+to be installed in compiler/linker default directories or their
+location will need to be adding to .config when building
+wpa_supplicant.
+
+Othen than this, the build should be more or less identical to Linux
+version, i.e., just run make after having created .config file. An
+additional tool, win_if_list.exe, can be built by running "make
+win_if_list".
+
+
+Building wpa_gui
+----------------
+
+wpa_gui uses Qt application framework from Trolltech. It can be built
+with the open source version of Qt4 and MinGW. Following commands can
+be used to build the binary in the Qt 4 Command Prompt:
+
+# go to the root directory of wpa_supplicant source code
+cd wpa_gui-qt4
+qmake -o Makefile wpa_gui.pro
+make
+# the wpa_gui.exe binary is created into 'release' subdirectory
+
+
+Using wpa_supplicant for Windows
+--------------------------------
+
+wpa_supplicant, wpa_cli, and wpa_gui behave more or less identically to
+Linux version, so instructions in README and example wpa_supplicant.conf
+should be applicable for most parts. In addition, there is another
+version of wpa_supplicant, wpasvc.exe, which can be used as a Windows
+service and which reads its configuration from registry instead of
+text file.
+
+When using access points in "hidden SSID" mode, ap_scan=2 mode need to
+be used (see wpa_supplicant.conf for more information).
+
+Windows NDIS/WinPcap uses quite long interface names, so some care
+will be needed when starting wpa_supplicant. Alternatively, the
+adapter description can be used as the interface name which may be
+easier since it is usually in more human-readable
+format. win_if_list.exe can be used to find out the proper interface
+name.
+
+Example steps in starting up wpa_supplicant:
+
+# win_if_list.exe
+ifname: \Device\NPF_GenericNdisWanAdapter
+description: Generic NdisWan adapter
+
+ifname: \Device\NPF_{769E012B-FD17-4935-A5E3-8090C38E25D2}
+description: Atheros Wireless Network Adapter (Microsoft's Packet Scheduler)
+
+ifname: \Device\NPF_{732546E7-E26C-48E3-9871-7537B020A211}
+description: Intel 8255x-based Integrated Fast Ethernet (Microsoft's Packet Scheduler)
+
+
+Since the example configuration used Atheros WLAN card, the middle one
+is the correct interface in this case. The interface name for -i
+command line option is the full string following "ifname:" (the
+"\Device\NPF_" prefix can be removed). In other words, wpa_supplicant
+would be started with the following command:
+
+# wpa_supplicant.exe -i'{769E012B-FD17-4935-A5E3-8090C38E25D2}' -c wpa_supplicant.conf -d
+
+-d optional enables some more debugging (use -dd for even more, if
+needed). It can be left out if debugging information is not needed.
+
+With the alternative mechanism for selecting the interface, this
+command has identical results in this case:
+
+# wpa_supplicant.exe -iAtheros -c wpa_supplicant.conf -d
+
+
+Simple configuration example for WPA-PSK:
+
+#ap_scan=2
+ctrl_interface=
+network={
+	ssid="test"
+	key_mgmt=WPA-PSK
+	proto=WPA
+	pairwise=TKIP
+	psk="secret passphrase"
+}
+
+(remove '#' from the comment out ap_scan line to enable mode in which
+wpa_supplicant tries to associate with the SSID without doing
+scanning; this allows APs with hidden SSIDs to be used)
+
+
+wpa_cli.exe and wpa_gui.exe can be used to interact with the
+wpa_supplicant.exe program in the same way as with Linux. Note that
+ctrl_interface is using UNIX domain sockets when built for cygwin, but
+the native build for Windows uses named pipes and the contents of the
+ctrl_interface configuration item is used to control access to the
+interface. Anyway, this variable has to be included in the configuration
+to enable the control interface.
+
+
+Example SDDL string formats:
+
+(local admins group has permission, but nobody else):
+
+ctrl_interface=SDDL=D:(A;;GA;;;BA)
+
+("A" == "access allowed", "GA" == GENERIC_ALL == all permissions, and
+"BA" == "builtin administrators" == the local admins.  The empty fields
+are for flags and object GUIDs, none of which should be required in this
+case.)
+
+(local admins and the local "power users" group have permissions,
+but nobody else):
+
+ctrl_interface=SDDL=D:(A;;GA;;;BA)(A;;GA;;;PU)
+
+(One ACCESS_ALLOWED ACE for GENERIC_ALL for builtin administrators, and
+one ACCESS_ALLOWED ACE for GENERIC_ALL for power users.)
+
+(close to wide open, but you have to be a valid user on
+the machine):
+
+ctrl_interface=SDDL=D:(A;;GA;;;AU)
+
+(One ACCESS_ALLOWED ACE for GENERIC_ALL for the "authenticated users"
+group.)
+
+This one would allow absolutely everyone (including anonymous
+users) -- this is *not* recommended, since named pipes can be attached
+to from anywhere on the network (i.e. there's no "this machine only"
+like there is with 127.0.0.1 sockets):
+
+ctrl_interface=SDDL=D:(A;;GA;;;BU)(A;;GA;;;AN)
+
+(BU == "builtin users", "AN" == "anonymous")
+
+See also [1] for the format of ACEs, and [2] for the possible strings
+that can be used for principal names.

+
+
+Starting wpa_supplicant as a Windows service (wpasvc.exe)
+---------------------------------------------------------
+
+wpa_supplicant can be started as a Windows service by using wpasvc.exe
+program that is alternative build of wpa_supplicant.exe. Most of the
+core functionality of wpasvc.exe is identical to wpa_supplicant.exe,
+but it is using Windows registry for configuration information instead
+of a text file and command line parameters. In addition, it can be
+registered as a service that can be started automatically or manually
+like any other Windows service.
+
+The root of wpa_supplicant configuration in registry is
+HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant. This level includes global
+parameters and a 'interfaces' subkey with all the interface configuration
+(adapter to confname mapping). Each such mapping is a subkey that has
+'adapter', 'config', and 'ctrl_interface' values.
+
+This program can be run either as a normal command line application,
+e.g., for debugging, with 'wpasvc.exe app' or as a Windows service.
+Service need to be registered with 'wpasvc.exe reg <full path to
+wpasvc.exe>'. Alternatively, 'wpasvc.exe reg' can be used to register
+the service with the current location of wpasvc.exe. After this, wpasvc
+can be started like any other Windows service (e.g., 'net start wpasvc')
+or it can be configured to start automatically through the Services tool
+in administrative tasks. The service can be unregistered with
+'wpasvc.exe unreg'.
+
+If the service is set to start during system bootup to make the
+network connection available before any user has logged in, there may
+be a long (half a minute or so) delay in starting up wpa_supplicant
+due to WinPcap needing a driver called "Network Monitor Driver" which
+is started by default on demand.
+
+To speed up wpa_supplicant start during system bootup, "Network
+Monitor Driver" can be configured to be started sooner by setting its
+startup type to System instead of the default Demand. To do this, open
+up Device Manager, select Show Hidden Devices, expand the "Non
+Plug-and-Play devices" branch, double click "Network Monitor Driver",
+go to the Driver tab, and change the Demand setting to System instead.
+
+Configuration data is in HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant\configs
+key. Each configuration profile has its own key under this. In terms of text
+files, each profile would map to a separate text file with possibly multiple
+networks. Under each profile, there is a networks key that lists all
+networks as a subkey. Each network has set of values in the same way as
+network block in the configuration file. In addition, blobs subkey has
+possible blobs as values.
+
+HKEY_LOCAL_MACHINE\SOFTWARE\wpa_supplicant\configs\test\networks\0000
+   ssid="example"
+   key_mgmt=WPA-PSK
+
+See win_example.reg for an example on how to setup wpasvc.exe
+parameters in registry. It can also be imported to registry as a
+starting point for the configuration.

+# wpa_supplicant depends on strong random number generation being available
+# from the operating system. os_get_random() function is used to fetch random
+# data when needed, e.g., for key generation. On Linux and BSD systems, this
+# works by reading /dev/urandom. It should be noted that the OS entropy pool
+# needs to be properly initialized before wpa_supplicant is started. This is
+# important especially on embedded devices that do not have a hardware random
+# number generator and may by default start up with minimal entropy available
+# for random number generation.
+#
+# As a safety net, wpa_supplicant is by default trying to internally collect
+# additional entropy for generating random data to mix in with the data fetched
+# from the OS. This by itself is not considered to be very strong, but it may
+# help in cases where the system pool is not initialized properly. However, it
+# is very strongly recommended that the system pool is initialized with enough
+# entropy either by using hardware assisted random number generator or by
+# storing state over device reboots.
+#
+# wpa_supplicant can be configured to maintain its own entropy store over
+# restarts to enhance random number generation. This is not perfect, but it is
+# much more secure than using the same sequence of random numbers after every
+# reboot. This can be enabled with -e<entropy file> command line option. The
+# specified file needs to be readable and writable by wpa_supplicant.
+#
+# If the os_get_random() is known to provide strong random data (e.g., on
+# Linux/BSD, the board in question is known to have reliable source of random
+# data from /dev/urandom), the internal wpa_supplicant random pool can be

+ * this table and select the entry that matches with the field name. The parser
+ * function (.parser) is then called to parse the actual value of the field.

+# wpa_supplicant depends on strong random number generation being available
+# from the operating system. os_get_random() function is used to fetch random
+# data when needed, e.g., for key generation. On Linux and BSD systems, this
+# works by reading /dev/urandom. It should be noted that the OS entropy pool
+# needs to be properly initialized before wpa_supplicant is started. This is
+# important especially on embedded devices that do not have a hardware random
+# number generator and may by default start up with minimal entropy available
+# for random number generation.
+#
+# As a safety net, wpa_supplicant is by default trying to internally collect
+# additional entropy for generating random data to mix in with the data fetched
+# from the OS. This by itself is not considered to be very strong, but it may
+# help in cases where the system pool is not initialized properly. However, it
+# is very strongly recommended that the system pool is initialized with enough
+# entropy either by using hardware assisted random number generator or by
+# storing state over device reboots.
+#
+# wpa_supplicant can be configured to maintain its own entropy store over
+# restarts to enhance random number generation. This is not perfect, but it is
+# much more secure than using the same sequence of random numbers after every
+# reboot. This can be enabled with -e<entropy file> command line option. The
+# specified file needs to be readable and writable by wpa_supplicant.
+#
+# If the os_get_random() is known to provide strong random data (e.g., on
+# Linux/BSD, the board in question is known to have reliable source of random
+# data from /dev/urandom), the internal wpa_supplicant random pool can be

+    <title>WPA</title>
+
+    <para>The original security mechanism of IEEE 802.11 standard was
+    not designed to be strong and has proven to be insufficient for
+    most networks that require some kind of security. Task group I
+    (Security) of IEEE 802.11 working group
+    (http://www.ieee802.org/11/) has worked to address the flaws of
+    the base standard and has in practice completed its work in May
+    2004. The IEEE 802.11i amendment to the IEEE 802.11 standard was
+    approved in June 2004 and published in July 2004.</para>
+
+    <para>Wi-Fi Alliance (http://www.wi-fi.org/) used a draft version
+    of the IEEE 802.11i work (draft 3.0) to define a subset of the
+    security enhancements that can be implemented with existing wlan
+    hardware. This is called Wi-Fi Protected Access&lt;TM&gt; (WPA). This
+    has now become a mandatory component of interoperability testing
+    and certification done by Wi-Fi Alliance. Wi-Fi provides
+    information about WPA at its web site
+    (http://www.wi-fi.org/OpenSection/protected_access.asp).</para>
+
+    <para>IEEE 802.11 standard defined wired equivalent privacy (WEP)
+    algorithm for protecting wireless networks. WEP uses RC4 with
+    40-bit keys, 24-bit initialization vector (IV), and CRC32 to
+    protect against packet forgery. All these choices have proven to
+    be insufficient: key space is too small against current attacks,
+    RC4 key scheduling is insufficient (beginning of the pseudorandom
+    stream should be skipped), IV space is too small and IV reuse
+    makes attacks easier, there is no replay protection, and non-keyed
+    authentication does not protect against bit flipping packet
+    data.</para>
+
+    <para>WPA is an intermediate solution for the security issues. It
+    uses Temporal Key Integrity Protocol (TKIP) to replace WEP. TKIP
+    is a compromise on strong security and possibility to use existing
+    hardware. It still uses RC4 for the encryption like WEP, but with
+    per-packet RC4 keys. In addition, it implements replay protection,
+    keyed packet authentication mechanism (Michael MIC).</para>
+
+    <para>Keys can be managed using two different mechanisms. WPA can
+    either use an external authentication server (e.g., RADIUS) and
+    EAP just like IEEE 802.1X is using or pre-shared keys without need
+    for additional servers. Wi-Fi calls these "WPA-Enterprise" and
+    "WPA-Personal", respectively. Both mechanisms will generate a
+    master session key for the Authenticator (AP) and Supplicant
+    (client station).</para>
+
+    <para>WPA implements a new key handshake (4-Way Handshake and
+    Group Key Handshake) for generating and exchanging data encryption
+    keys between the Authenticator and Supplicant. This handshake is
+    also used to verify that both Authenticator and Supplicant know
+    the master session key. These handshakes are identical regardless
+    of the selected key management mechanism (only the method for
+    generating master session key changes).</para>
+  </refsect1>
+
+  <refsect1>
+    <title>IEEE 802.11i / WPA2</title>
+
+    <para>The design for parts of IEEE 802.11i that were not included
+    in WPA has finished (May 2004) and this amendment to IEEE 802.11
+    was approved in June 2004. Wi-Fi Alliance is using the final IEEE
+    802.11i as a new version of WPA called WPA2. This includes, e.g.,
+    support for more robust encryption algorithm (CCMP: AES in Counter
+    mode with CBC-MAC) to replace TKIP and optimizations for handoff
+    (reduced number of messages in initial key handshake,
+    pre-authentication, and PMKSA caching).</para>

+    <title>Overview</title>
+
+    <para>wpa_cli is a text-based frontend program for interacting
+    with wpa_supplicant. It is used to query current status, change
+    configuration, trigger events, and request interactive user
+    input.</para>
+
+    <para>wpa_cli can show the current authentication status, selected
+    security mode, dot11 and dot1x MIBs, etc. In addition, it can
+    configure some variables like EAPOL state machine parameters and
+    trigger events like reassociation and IEEE 802.1X
+    logoff/logon. wpa_cli provides a user interface to request
+    authentication information, like username and password, if these
+    are not included in the configuration. This can be used to
+    implement, e.g., one-time-passwords or generic token card
+    authentication where the authentication is based on a
+    challenge-response that uses an external device for generating the
+    response.</para>
+
+    <para>The control interface of wpa_supplicant can be configured to
+    allow non-root user access (ctrl_interface GROUP= parameter in the
+    configuration file). This makes it possible to run wpa_cli with a
+    normal user account.</para>
+
+    <para>wpa_cli supports two modes: interactive and command
+    line. Both modes share the same command set and the main
+    difference is in interactive mode providing access to unsolicited
+    messages (event messages, username/password requests).</para>
+
+    <para>Interactive mode is started when wpa_cli is executed without
+    including the command as a command line parameter. Commands are
+    then entered on the wpa_cli prompt. In command line mode, the same
+    commands are entered as command line arguments for wpa_cli.</para>
+ </refsect1>
+ <refsect1>
+   <title>Interactive authentication parameters request</title>
+
+   <para>When wpa_supplicant need authentication parameters, like
+   username and password, which are not present in the configuration
+   file, it sends a request message to all attached frontend programs,
+   e.g., wpa_cli in interactive mode. wpa_cli shows these requests
+   with "CTRL-REQ-&lt;type&gt;-&lt;id&gt;:&lt;text&gt;"
+   prefix. &lt;type&gt; is IDENTITY, PASSWORD, or OTP
+   (one-time-password). &lt;id&gt; is a unique identifier for the
+   current network. &lt;text&gt; is description of the request. In
+   case of OTP request, it includes the challenge from the
+   authentication server.</para>
+
+    <para>The reply to these requests can be given with
+    <emphasis>identity</emphasis>, <emphasis>password</emphasis>, and
+    <emphasis>otp</emphasis> commands. &lt;id&gt; needs to be copied from
+    the matching request. <emphasis>password</emphasis> and
+    <emphasis>otp</emphasis> commands can be used regardless of whether
+    the request was for PASSWORD or OTP. The main difference between these
+    two commands is that values given with <emphasis>password</emphasis> are
+    remembered as long as wpa_supplicant is running whereas values given
+    with <emphasis>otp</emphasis> are used only once and then forgotten,
+    i.e., wpa_supplicant will ask frontend for a new value for every use.
+    This can be used to implement one-time-password lists and generic token
+    card -based authentication.</para>
+
+    <para>Example request for password and a matching reply:</para>
+
+<blockquote><programlisting>
+CTRL-REQ-PASSWORD-1:Password needed for SSID foobar
+> password 1 mysecretpassword
+</programlisting></blockquote>
+
+    <para>Example request for generic token card challenge-response:</para>
+
+<blockquote><programlisting>
+CTRL-REQ-OTP-2:Challenge 1235663 needed for SSID foobar
+> otp 2 9876

+
+    <para><command>wpa_priv</command> is a privilege separation helper that
+    minimizes the size of <command>wpa_supplicant</command> code that needs
+    to be run with root privileges.</para>
+
+    <para>If enabled, privileged operations are done in the wpa_priv process
+    while leaving rest of the code (e.g., EAP authentication and WPA
+    handshakes) to operate in an unprivileged process (wpa_supplicant) that
+    can be run as non-root user. Privilege separation restricts the effects
+    of potential software errors by containing the majority of the code in an
+    unprivileged process to avoid the possibility of a full system
+    compromise.</para>
+
+    <para><command>wpa_priv</command> needs to be run with network admin
+    privileges (usually, root user). It opens a UNIX domain socket for each
+    interface that is included on the command line; any other interface will
+    be off limits for <command>wpa_supplicant</command> in this kind of
+    configuration. After this, <command>wpa_supplicant</command> can be run as
+    a non-root user (e.g., all standard users on a laptop or as a special
+    non-privileged user account created just for this purpose to limit access
+    to user files even further).</para>
+  </refsect1>
+  <refsect1>
+    <title>Example configuration</title>
+
+    <para>The following steps are an example of how to configure
+    <command>wpa_priv</command> to allow users in the
+    <emphasis>wpapriv</emphasis> group to communicate with
+    <command>wpa_supplicant</command> with privilege separation:</para>
+
+    <para>Create user group (e.g., wpapriv) and assign users that
+    should be able to use wpa_supplicant into that group.</para>
+
+    <para>Create /var/run/wpa_priv directory for UNIX domain sockets and
+    control user access by setting it accessible only for the wpapriv
+    group:</para>
+
+<blockquote><programlisting>
+mkdir /var/run/wpa_priv
+chown root:wpapriv /var/run/wpa_priv
+chmod 0750 /var/run/wpa_priv
+</programlisting></blockquote>
+
+    <para>Start <command>wpa_priv</command> as root (e.g., from system
+    startup scripts) with the enabled interfaces configured on the
+    command line:</para>

+    <para>
+    Wireless networks do not require physical access to the network equipment
+    in the same way as wired networks. This makes it easier for unauthorized
+    users to passively monitor a network and capture all transmitted frames.
+    In addition, unauthorized use of the network is much easier. In many cases,
+    this can happen even without user's explicit knowledge since the wireless
+    LAN adapter may have been configured to automatically join any available
+    network.
+    </para>
+
+    <para>
+    Link-layer encryption can be used to provide a layer of security for
+    wireless networks. The original wireless LAN standard, IEEE 802.11,
+    included a simple encryption mechanism, WEP. However, that proved to
+    be flawed in many areas and network protected with WEP cannot be consider
+    secure. IEEE 802.1X authentication and frequently changed dynamic WEP keys
+    can be used to improve the network security, but even that has inherited
+    security issues due to the use of WEP for encryption. Wi-Fi Protected
+    Access and IEEE 802.11i amendment to the wireless LAN standard introduce
+    a much improvement mechanism for securing wireless networks. IEEE 802.11i
+    enabled networks that are using CCMP (encryption mechanism based on strong
+    cryptographic algorithm AES) can finally be called secure used for
+    applications which require efficient protection against unauthorized
+    access.

+    <para><command>wpa_supplicant</command> is an implementation of
+    the WPA Supplicant component, i.e., the part that runs in the
+    client stations. It implements WPA key negotiation with a WPA
+    Authenticator and EAP authentication with Authentication
+    Server. In addition, it controls the roaming and IEEE 802.11
+    authentication/association of the wireless LAN driver.</para>
+
+    <para><command>wpa_supplicant</command> is designed to be a
+    "daemon" program that runs in the background and acts as the
+    backend component controlling the wireless

+    frontend programs and an example text-based frontend,
+    <command>wpa_cli</command>, is included with
+    wpa_supplicant.</para>
+
+    <para>Before wpa_supplicant can do its work, the network interface
+    must be available.  That means that the physical device must be
+    present and enabled, and the driver for the device must be
+    loaded. The daemon will exit immediately if the device is not already
+    available.</para>
+
+    <para>After <command>wpa_supplicant</command> has configured the
+    network device, higher level configuration such as DHCP may

+Automatic regression and interoperability testing of wpa_supplicant's
+IEEE 802.1X/EAPOL authentication
+
+Test program:
+- Linked some parts of IEEE 802.1X Authenticator implementation from
+  hostapd (RADIUS client and RADIUS processing, EAP<->RADIUS
+  encapsulation/decapsulation) into wpa_supplicant.
+- Replaced wpa_supplicant.c and wpa.c with test code that trigger
+  IEEE 802.1X authentication automatically without need for wireless
+  client card or AP.
+- For EAP methods that generate keying material, the key derived by the
+  Supplicant is verified to match with the one received by the (now
+  integrated) Authenticator.
+
+The full automated test suite can now be run in couple of seconds, but
+I'm more than willing to add new RADIUS authentication servers to make
+this take a bit more time.. ;-) As an extra bonus, this can also be
+seen as automatic regression/interoperability testing for the RADIUS
+server, too.
+
+In order for me to be able to use a new authentication server, the
+server need to be available from Internet (at least from one static IP
+address) and I will need to get suitable user name/password pairs,
+certificates, and private keys for testing use. Other alternative
+would be to get an evaluation version of the server so that I can
+install it on my own test setup. If you are interested in providing
+either server access or evaluation version, please contact me
+(j@w1.fi).

+1) PEAPv1 required new label, "client PEAP encryption" instead of "client EAP
+   encryption", during key derivation (requires phase1="peaplabel=1" in the
+   network configuration in wpa_supplicant.conf)
+2) used FreeRADIUS as inner auth server
+5) PEAPv1 required termination of negotiation on tunneled EAP-Success and new
+   label in key deriviation
+   (phase1="peap_outer_success=0 peaplabel=1") (in "IETF Draft 5" mode)
+6) Authenticator simulator required patching for handling Access-Accept within
+   negotiation (for the first EAP-Success of LEAP)
+7) tested only with an older (incompatible) draft of EAP-PSK; FreeRADIUS does
+   not support the current EAP-PSK (RFC) specification
+8) PEAPv1 used non-standard version negotiation (client had to force v1 even
+   though server reported v0 as the highest supported version)
+9) only EAP-TTLS/EAP-TNC tested, i.e., test did not include proper sequence of
+   client authentication followed by TNC inside the tunnel
+10) worked only with special compatibility code to match the IKEv2 server
+    implementation

+To do:
+- add support for WPA with ap_scan=0 (update selected cipher etc. based on
+  AssocInfo; make sure these match with configuration)
+- consider closing smart card / PCSC connection when EAP-SIM/EAP-AKA
+  authentication has been completed (cache scard data based on serial#(?)
+  and try to optimize next connection if the same card is present for next
+  auth)
+- on disconnect event, could try to associate with another AP if one is
+  present in scan results; would need to update scan results periodically..
+- if driver/hw is not WPA2 capable, must remove WPA_PROTO_RSN flag from
+  ssid->proto fields to avoid detecting downgrade attacks when the driver
+  is not reporting RSN IE, but msg 3/4 has one
+- Cisco AP and non-zero keyidx for unicast -> map to broadcast
+  (actually, this already works with driver_ndis; so maybe just change
+  driver_*.c to do the mapping for drivers that cannot handle non-zero keyidx
+  for unicast); worked also with Host AP driver and madwifi
+- IEEE 802.1X and key update with driver_ndis?? wpa_supplicant did not seem
+  to see unencrypted EAPOL-Key frames at all..
+- EAP-PAX with PAX_SEC
+- EAP (RFC 3748)
+  * OTP Extended Responses (Sect. 5.5)
+- test what happens if authenticator sends EAP-Success before real EAP
+  authentication ("canned" Success); this should be ignored based on
+  RFC 3748 Sect. 4.2
+- test compilation with gcc -W options (more warnings?)
+  (Done once; number of unused function arguments still present)
+- add proper support for using dot11RSNAConfigSATimeout
+- ctrl_iface: get/set/remove blob
+- use doc/docbook/*.sgml and docbook2{txt,html,pdf} to replace README and
+  web pages including the same information.. i.e., have this information only
+  in one page; how to build a PDF file with all the SGML included?
+- EAP-POTP/RSA SecurID profile (RFC 4793)
+- document wpa_gui build and consider adding it to 'make install'
+- test madwifi with pairwise=TKIP group=WEP104
+- consider merging hostapd and wpa_supplicant PMKSA cache implementations
+- consider redesigning pending EAP requests (identity/password/otp from
+  ctrl_iface) by moving the retrying of the previous request into EAP
+  state machine so that EAPOL state machine is not needed for this
+- rfc4284.txt (network selection for eap)
+- www pages about configuring wpa_supplicant:
+  * global options (ap_scan, ctrl_interfaces) based on OS/driver
+  * network block
+  * key_mgmt selection
+  * WPA parameters
+  * EAP options (one page for each method)
+  * "configuration wizard" (step 1: select OS, step 2: select driver, ...) to
+    generate example configuration
+- error path in rsn_preauth_init: should probably deinit l2_packet handlers
+  if something fails; does something else need deinit?
+- consider moving SIM card functionality (IMSI fetching) away from eap.c;
+  this should likely happen before EAP is initialized for authentication;
+  now IMSI is read only after receiving EAP-Identity/Request, but since it is
+  really needed for all cases, reading IMSI and generating Identity string
+  could very well be done before EAP has been started
+- try to work around race in receiving association event and first EAPOL
+  message
+- try to work around race in configuring PTK and sending msg 4/4 (some NDIS
+  drivers with ndiswrapper end up not being able to complete 4-way handshake
+  in some cases; extra delay before setting the key seems to help)
+- add wpa_secure_memzero() macro and secure implementation (volatile u8*) to
+  clear memory; this would be used to clear temporary buffers containing
+  private data (e.g., keys); the macro can be defined to NOP in order to save
+  space (i.e., no code should depend on the macro doing something)
+- make sure that TLS session cache is not shared between EAP types or if it
+  is, that the cache entries are bound to only one EAP type; e.g., cache entry
+  created with EAP-TLS must not be allowed to do fast re-auth with EAP-TTLS
+- consider moving eap_tls_build_ack() call into eap_tls_process_helper()
+  (it seems to be called always if helper returns 1)
+  * could need to modify eap_{ttls,peap,fast}_decrypt to do same
+- add support for fetching full user cert chain from Windows certificate
+  stores even when there are intermediate CA certs that are not in the
+  configured ca_cert store (e.g., ROOT) (they could be, e.g., in CA store)
+- clean up common.[ch]
+- change TLS/crypto library interface to use a structure of function
+  pointers and helper inline functions (like driver_ops) instead of
+  requiring every TLS wrapper to implement all functions
+- add support for encrypted configuration fields (e.g., password, psk,
+  passphrase, pin)
+- wpa_gui: add support for setting and showing priority
+- cleanup TLS/PEAP/TTLS/FAST fragmentation: both the handshake and Appl. Data
+  phases should be able to use the same functions for this;
+  the last step in processing sent should be this code and rest of the code
+  should not need to care about fragmentation at all
+- test EAP-FAST peer with OpenSSL and verify that fallback to full handshake
+  (ServerHello followed by something else than ChangeCipherSpec)

+##### Example wpa_supplicant configuration file ###############################
+#
+# This file describes configuration file format and lists all available option.
+# Please also take a look at simpler configuration examples in 'examples'
+# subdirectory.
+#
+# Empty lines and lines starting with # are ignored
+
+# NOTE! This file may contain password information and should probably be made
+# readable only by root user on multiuser systems.
+
+# Note: All file paths in this configuration file should use full (absolute,
+# not relative to working directory) path in order to allow working directory
+# to be changed. This can happen if wpa_supplicant is run in the background.
+
+# Whether to allow wpa_supplicant to update (overwrite) configuration
+#
+# This option can be used to allow wpa_supplicant to overwrite configuration
+# file whenever configuration is changed (e.g., new network block is added with
+# wpa_cli or wpa_gui, or a password is changed). This is required for
+# wpa_cli/wpa_gui to be able to store the configuration changes permanently.
+# Please note that overwriting configuration file will remove the comments from
+# it.
+#update_config=1
+
+# global configuration (shared by all network blocks)
+#
+# Parameters for the control interface. If this is specified, wpa_supplicant
+# will open a control interface that is available for external programs to
+# manage wpa_supplicant. The meaning of this string depends on which control
+# interface mechanism is used. For all cases, the existence of this parameter
+# in configuration is used to determine whether the control interface is
+# enabled.
+#
+# For UNIX domain sockets (default on Linux and BSD): This is a directory that
+# will be created for UNIX domain sockets for listening to requests from
+# external programs (CLI/GUI, etc.) for status information and configuration.
+# The socket file will be named based on the interface name, so multiple
+# wpa_supplicant processes can be run at the same time if more than one
+# interface is used.
+# /var/run/wpa_supplicant is the recommended directory for sockets and by
+# default, wpa_cli will use it when trying to connect with wpa_supplicant.
+#
+# Access control for the control interface can be configured by setting the
+# directory to allow only members of a group to use sockets. This way, it is
+# possible to run wpa_supplicant as root (since it needs to change network
+# configuration and open raw sockets) and still allow GUI/CLI components to be
+# run as non-root users. However, since the control interface can be used to
+# change the network configuration, this access needs to be protected in many
+# cases. By default, wpa_supplicant is configured to use gid 0 (root). If you
+# want to allow non-root users to use the control interface, add a new group
+# and change this value to match with that group. Add users that should have
+# control interface access to this group. If this variable is commented out or
+# not included in the configuration file, group will not be changed from the
+# value it got by default when the directory or socket was created.
+#
+# When configuring both the directory and group, use following format:
+# DIR=/var/run/wpa_supplicant GROUP=wheel
+# DIR=/var/run/wpa_supplicant GROUP=0
+# (group can be either group name or gid)
+#
+# For UDP connections (default on Windows): The value will be ignored. This
+# variable is just used to select that the control interface is to be created.
+# The value can be set to, e.g., udp (ctrl_interface=udp)
+#
+# For Windows Named Pipe: This value can be used to set the security descriptor
+# for controlling access to the control interface. Security descriptor can be
+# set using Security Descriptor String Format (see http://msdn.microsoft.com/
+# library/default.asp?url=/library/en-us/secauthz/security/
+# security_descriptor_string_format.asp). The descriptor string needs to be
+# prefixed with SDDL=. For example, ctrl_interface=SDDL=D: would set an empty
+# DACL (which will reject all connections). See README-Windows.txt for more
+# information about SDDL string format.

+# wpa_supplicant is implemented based on IEEE Std 802.1X-2004 which defines
+# EAPOL version 2. However, there are many APs that do not handle the new
+# version number correctly (they seem to drop the frames completely). In order
+# to make wpa_supplicant interoperate with these APs, the version number is set
+# to 1 by default. This configuration value can be used to set it to the new
+# version (2).
+eapol_version=1
+
+# AP scanning/selection
+# By default, wpa_supplicant requests driver to perform AP scanning and then
+# uses the scan results to select a suitable AP. Another alternative is to
+# allow the driver to take care of AP scanning and selection and use
+# wpa_supplicant just to process EAPOL frames based on IEEE 802.11 association
+# information from the driver.
+# 1: wpa_supplicant initiates scanning and AP selection; if no APs matching to
+#    the currently enabled networks are found, a new network (IBSS or AP mode
+#    operation) may be initialized (if configured) (default)
+# 0: driver takes care of scanning, AP selection, and IEEE 802.11 association
+#    parameters (e.g., WPA IE generation); this mode can also be used with
+#    non-WPA drivers when using IEEE 802.1X mode; do not try to associate with
+#    APs (i.e., external program needs to control association). This mode must
+#    also be used when using wired Ethernet drivers.
+# 2: like 0, but associate with APs using security policy and SSID (but not
+#    BSSID); this can be used, e.g., with ndiswrapper and NDIS drivers to
+#    enable operation with hidden SSIDs and optimized roaming; in this mode,
+#    the network blocks in the configuration file are tried one by one until
+#    the driver reports successful association; each network block should have
+#    explicit security policy (i.e., only one option in the lists) for
+#    key_mgmt, pairwise, group, proto variables
+# When using IBSS or AP mode, ap_scan=2 mode can force the new network to be
+# created immediately regardless of scan results. ap_scan=1 mode will first try
+# to scan for existing networks and only if no matches with the enabled
+# networks are found, a new IBSS or AP mode network is created.

+#	EAP-PSK/PAX/SAKE/GPSK.
+# anonymous_identity: Anonymous identity string for EAP (to be used as the
+#	unencrypted identity with EAP types that support different tunnelled
+#	identity, e.g., EAP-TTLS). This field can also be used with
+#	EAP-SIM/AKA/AKA' to store the pseudonym identity.
+# password: Password string for EAP. This field can include either the
+#	plaintext password (using ASCII or hex string) or a NtPasswordHash
+#	(16-byte MD4 hash of password) in hash:<32 hex digits> format.
+#	NtPasswordHash can only be used when the password is for MSCHAPv2 or
+#	MSCHAP (EAP-MSCHAPv2, EAP-TTLS/MSCHAPv2, EAP-TTLS/MSCHAP, LEAP).
+#	EAP-PSK (128-bit PSK), EAP-PAX (128-bit PSK), and EAP-SAKE (256-bit
+#	PSK) is also configured using this field. For EAP-GPSK, this is a
+#	variable length PSK. ext:<name of external password field> format can
+#	be used to indicate that the password is stored in external storage.
+# ca_cert: File path to CA certificate file (PEM/DER). This file can have one
+#	or more trusted CA certificates. If ca_cert and ca_path are not
+#	included, server certificate will not be verified. This is insecure and
+#	a trusted CA certificate should always be configured when using
+#	EAP-TLS/TTLS/PEAP. Full path should be used since working directory may
+#	change when wpa_supplicant is run in the background.
+#
+#	Alternatively, this can be used to only perform matching of the server
+#	certificate (SHA-256 hash of the DER encoded X.509 certificate). In
+#	this case, the possible CA certificates in the server certificate chain
+#	are ignored and only the server certificate is verified. This is
+#	configured with the following format:
+#	hash:://server/sha256/cert_hash_in_hex
+#	For example: "hash://server/sha256/
+#	5a1bc1296205e6fdbe3979728efe3920798885c1c4590b5f90f43222d239ca6a"
+#
+#	On Windows, trusted CA certificates can be loaded from the system
+#	certificate store by setting this to cert_store://<name>, e.g.,
+#	ca_cert="cert_store://CA" or ca_cert="cert_store://ROOT".
+#	Note that when running wpa_supplicant as an application, the user
+#	certificate store (My user account) is used, whereas computer store
+#	(Computer account) is used when running wpasvc as a service.
+# ca_path: Directory path for CA certificate files (PEM). This path may
+#	contain multiple CA certificates in OpenSSL format. Common use for this
+#	is to point to system trusted CA list which is often installed into
+#	directory like /etc/ssl/certs. If configured, these certificates are
+#	added to the list of trusted CAs. ca_cert may also be included in that
+#	case, but it is not required.
+# client_cert: File path to client certificate file (PEM/DER)
+#	Full path should be used since working directory may change when
+#	wpa_supplicant is run in the background.
+#	Alternatively, a named configuration blob can be used by setting this
+#	to blob://<blob name>.
+# private_key: File path to client private key file (PEM/DER/PFX)
+#	When PKCS#12/PFX file (.p12/.pfx) is used, client_cert should be
+#	commented out. Both the private key and certificate will be read from
+#	the PKCS#12 file in this case. Full path should be used since working
+#	directory may change when wpa_supplicant is run in the background.
+#	Windows certificate store can be used by leaving client_cert out and
+#	configuring private_key in one of the following formats:
+#	cert://substring_to_match
+#	hash://certificate_thumbprint_in_hex
+#	for example: private_key="hash://63093aa9c47f56ae88334c7b65a4"
+#	Note that when running wpa_supplicant as an application, the user
+#	certificate store (My user account) is used, whereas computer store
+#	(Computer account) is used when running wpasvc as a service.
+#	Alternatively, a named configuration blob can be used by setting this
+#	to blob://<blob name>.
+# private_key_passwd: Password for private key file (if left out, this will be
+#	asked through control interface)
+# dh_file: File path to DH/DSA parameters file (in PEM format)
+#	This is an optional configuration file for setting parameters for an
+#	ephemeral DH key exchange. In most cases, the default RSA
+#	authentication does not use this configuration. However, it is possible
+#	setup RSA to use ephemeral DH key exchange. In addition, ciphers with
+#	DSA keys always use ephemeral DH keys. This can be used to achieve
+#	forward secrecy. If the file is in DSA parameters format, it will be
+#	automatically converted into DH params.
+# subject_match: Substring to be matched against the subject of the
+#	authentication server certificate. If this string is set, the server
+#	sertificate is only accepted if it contains this string in the subject.
+#	The subject string is in following format:
+#	/C=US/ST=CA/L=San Francisco/CN=Test AS/emailAddress=as@example.com
+# altsubject_match: Semicolon separated string of entries to be matched against
+#	the alternative subject name of the authentication server certificate.
+#	If this string is set, the server sertificate is only accepted if it
+#	contains one of the entries in an alternative subject name extension.
+#	altSubjectName string is in following format: TYPE:VALUE
+#	Example: EMAIL:server@example.com
+#	Example: DNS:server.example.com;DNS:server2.example.com
+#	Following types are supported: EMAIL, DNS, URI
+# phase1: Phase1 (outer authentication, i.e., TLS tunnel) parameters
+#	(string with field-value pairs, e.g., "peapver=0" or
+#	"peapver=1 peaplabel=1")
+#	'peapver' can be used to force which PEAP version (0 or 1) is used.
+#	'peaplabel=1' can be used to force new label, "client PEAP encryption",
+#	to be used during key derivation when PEAPv1 or newer. Most existing
+#	PEAPv1 implementation seem to be using the old label, "client EAP
+#	encryption", and wpa_supplicant is now using that as the default value.
+#	Some servers, e.g., Radiator, may require peaplabel=1 configuration to
+#	interoperate with PEAPv1; see eap_testing.txt for more details.
+#	'peap_outer_success=0' can be used to terminate PEAP authentication on
+#	tunneled EAP-Success. This is required with some RADIUS servers that
+#	implement draft-josefsson-pppext-eap-tls-eap-05.txt (e.g.,
+#	Lucent NavisRadius v4.4.0 with PEAP in "IETF Draft 5" mode)
+#	include_tls_length=1 can be used to force wpa_supplicant to include
+#	TLS Message Length field in all TLS messages even if they are not
+#	fragmented.
+#	sim_min_num_chal=3 can be used to configure EAP-SIM to require three
+#	challenges (by default, it accepts 2 or 3)
+#	result_ind=1 can be used to enable EAP-SIM and EAP-AKA to use
+#	protected result indication.
+#	'crypto_binding' option can be used to control PEAPv0 cryptobinding
+#	behavior:
+#	 * 0 = do not use cryptobinding (default)
+#	 * 1 = use cryptobinding if server supports it
+#	 * 2 = require cryptobinding
+#	EAP-WSC (WPS) uses following options: pin=<Device Password> or
+#	pbc=1.
+# phase2: Phase2 (inner authentication with TLS tunnel) parameters
+#	(string with field-value pairs, e.g., "auth=MSCHAPV2" for EAP-PEAP or
+#	"autheap=MSCHAPV2 autheap=MD5" for EAP-TTLS)
+#
+# TLS-based methods can use the following parameters to control TLS behavior
+# (these are normally in the phase1 parameter, but can be used also in the
+# phase2 parameter when EAP-TLS is used within the inner tunnel):
+# tls_allow_md5=1 - allow MD5-based certificate signatures (depending on the
+#	TLS library, these may be disabled by default to enforce stronger
+#	security)
+# tls_disable_time_checks=1 - ignore certificate validity time (this requests
+#	the TLS library to accept certificates even if they are not currently
+#	valid, i.e., have expired or have not yet become valid; this should be
+#	used only for testing purposes)
+# tls_disable_session_ticket=1 - disable TLS Session Ticket extension
+# tls_disable_session_ticket=0 - allow TLS Session Ticket extension to be used
+#	Note: If not set, this is automatically set to 1 for EAP-TLS/PEAP/TTLS
+#	as a workaround for broken authentication server implementations unless
+#	EAP workarounds are disabled with eap_workarounds=0.
+#	For EAP-FAST, this must be set to 0 (or left unconfigured for the
+#	default value to be used automatically).
+#
+# Following certificate/private key fields are used in inner Phase2
+# authentication when using EAP-TTLS or EAP-PEAP.
+# ca_cert2: File path to CA certificate file. This file can have one or more
+#	trusted CA certificates. If ca_cert2 and ca_path2 are not included,
+#	server certificate will not be verified. This is insecure and a trusted
+#	CA certificate should always be configured.
+# ca_path2: Directory path for CA certificate files (PEM)
+# client_cert2: File path to client certificate file
+# private_key2: File path to client private key file
+# private_key2_passwd: Password for private key file
+# dh_file2: File path to DH/DSA parameters file (in PEM format)
+# subject_match2: Substring to be matched against the subject of the
+#	authentication server certificate.
+# altsubject_match2: Substring to be matched against the alternative subject
+#	name of the authentication server certificate.
+#
+# fragment_size: Maximum EAP fragment size in bytes (default 1398).
+#	This value limits the fragment size for EAP methods that support
+#	fragmentation (e.g., EAP-TLS and EAP-PEAP). This value should be set
+#	small enough to make the EAP messages fit in MTU of the network
+#	interface used for EAPOL. The default value is suitable for most
+#	cases.
+#
+# EAP-FAST variables:
+# pac_file: File path for the PAC entries. wpa_supplicant will need to be able
+#	to create this file and write updates to it when PAC is being
+#	provisioned or refreshed. Full path to the file should be used since
+#	working directory may change when wpa_supplicant is run in the
+#	background. Alternatively, a named configuration blob can be used by
+#	setting this to blob://<blob name>
+# phase1: fast_provisioning option can be used to enable in-line provisioning
+#         of EAP-FAST credentials (PAC):
+#         0 = disabled,
+#         1 = allow unauthenticated provisioning,
+#         2 = allow authenticated provisioning,
+#         3 = allow both unauthenticated and authenticated provisioning
+#	fast_max_pac_list_len=<num> option can be used to set the maximum
+#		number of PAC entries to store in a PAC list (default: 10)
+#	fast_pac_format=binary option can be used to select binary format for
+#		storing PAC entries in order to save some space (the default
+#		text format uses about 2.5 times the size of minimal binary
+#		format)
+#
+# wpa_supplicant supports number of "EAP workarounds" to work around
+# interoperability issues with incorrectly behaving authentication servers.
+# These are enabled by default because some of the issues are present in large
+# number of authentication servers. Strict EAP conformance mode can be
+# configured by disabling workarounds with eap_workaround=0.
+
+# Station inactivity limit
+#
+# If a station does not send anything in ap_max_inactivity seconds, an
+# empty data frame is sent to it in order to verify whether it is
+# still in range. If this frame is not ACKed, the station will be
+# disassociated and then deauthenticated. This feature is used to
+# clear station table of old entries when the STAs move out of the
+# range.
+#
+# The station can associate again with the AP if it is still in range;
+# this inactivity poll is just used as a nicer way of verifying
+# inactivity; i.e., client will not report broken connection because
+# disassociation frame is not sent immediately without first polling
+# the STA with a data frame.
+# default: 300 (i.e., 5 minutes)
+#ap_max_inactivity=300
+
+# DTIM period in Beacon intervals for AP mode (default: 2)
+#dtim_period=2
+
+# disable_ht: Whether HT (802.11n) should be disabled.
+# 0 = HT enabled (if AP supports it)
+# 1 = HT disabled
+#
+# disable_ht40: Whether HT-40 (802.11n) should be disabled.
+# 0 = HT-40 enabled (if AP supports it)
+# 1 = HT-40 disabled
+#
+# disable_sgi: Whether SGI (short guard interval) should be disabled.
+# 0 = SGI enabled (if AP supports it)
+# 1 = SGI disabled
+#
+# ht_mcs:  Configure allowed MCS rates.
+#  Parsed as an array of bytes, in base-16 (ascii-hex)
+# ht_mcs=""                                   // Use all available (default)

+# ht_mcs="0xff ff 00 00 00 00 00 00 00 00 "   // Use MCS 0-15 only
+#
+# disable_max_amsdu:  Whether MAX_AMSDU should be disabled.
+# -1 = Do not make any changes.
+# 0  = Enable MAX-AMSDU if hardware supports it.
+# 1  = Disable AMSDU
+#
+# ampdu_density:  Allow overriding AMPDU density configuration.
