Two cleanups: tcb table expansion failure is not really a survivable
event, we do not have any viable way to continue. No wonder most
places where that is detected have FIXMEs.
It's way simpler to treat as fatal failure, and handle it inside
tcb table expansion finctions.
Second cleanup: tidy up haphazard locations of a few externs.
* defs.h: Change return type of expand_tcbtab() to void.
Declare change_syscall().
* process.c: Change all callsites of alloctcb(), alloc_tcb() and
fork_tcb(), removing now-redundant error checks.

Change all callsites of alloctcb(), alloc_tcb() and

(alloc_tcb): On failure to expand, print a message, clean up, and exit.
* util.c (setbpt): Remove extern declaration from function body.

Output format fixes, improving the situation after recent
change which added beeter handling of processes suddenly
disappearing. Now we often do not finish last line
before exiting in those cases.
The only change affecting something other than output
is change in umovestr where we were calling
abort() on ptrace error.
* strace.c (trace): If trace_syscall() failed with ESRCH,
finish current output line with " <unfinished ...>".
(mp_ioctl): While we are at it, fix gross style mismatch
in this function definition. No code chages.
* syscall.c (trace_syscall): If decode fails on syscall exit,
finish current output line with "= ? <unavailable>".
* util.c (umoven): Do not complain if error is ESRCH.

convert all remaining old style C parameter declarations
in this file.

* net.c (sys_accept): Properly decode third argument as pointer to
2008-12-30 Denys Vlasenko <>
Experimental support for -D option.
Unlike normal case, with -D *grandparent* process exec's,
becoming a traced process. Child exits (this prevents traced process
from having children it doesn't expect to have), and grandchild
attaches to grandparent similarly to strace -p PID.
This allows for more transparent interaction in cases
when process and its parent are communicating via signals,
wait() etc. Without -D, strace process gets lodged in between,
disrupting parent<->child link.
* strace.c: Add global flag variable daemonized_tracer for -D option.
(startup_attach): If -D, fork and block parent in pause().
In this case we are already a child, we in fact created a grandchild.
After attaching to grandparent, grandchild SIGKILLs parent.
(startup_child): If -D, parent blocks in wait(), then
execs the program to strace. Normally (w/o -D), it is child
who execs the program.
(main): Detect -D option, call startup_attach() if it is given.

Make strace detect when traced process suddenly disappeared
(prime example is randomly arriving SIGKILL).
* defs.h (do_ptrace, ptrace_restart): Declare new functions
* process.c: Use ptrace_restart instead of bare ptrace.
This catches and records ESRCH errors.
Print "<unavailable>" if syscall decode or result can't be
determined because of an earlier error in ptrace()
* syscall.c (trace_syscall): Stop indiscriminately bailing out
on errors, print "syscall(????" or even "????(????" but continue.
* util.c (do_ptrace, ptrace_restart): Define new functions.

2001-10-16 John Hughes <john@Calva.COM>
* util.c (umovestr): UnixWare (svr4?) returns 0 when trying
to read unmapped page. Make it possible to strace ksh.

breakpoint after attaching to child.
2001-10-02 David Mosberger <>

[IA64] Define ia32 socket, ipc, and extra syscall numbers.
* linux/ (regexp): Also handle <asm/ioctls.h> so we
don't miss the tty ioctls (unfortunately, some of the sound timer
ioctls are in conflict with them!).
* util.c (setbpt) [IA64]: Add ia32 support (by Don Dugger).
(clrbpt) [IA64]: Ditto.
* syscall.c (internal_syscall): Handle SYS_clone2, SYS32_wait4,

2001-04-11 David Mosberger <>

were showing it as PT_WRITE_U! Fix from Maxime Henrion.

sometimes too few. Fix suggested by Richard Kettlewell.

the struct from bits/sigcontext.h already which signal.h includes.
