| About the PPP code: |
| |
| The PPP code is not our "own" code - we just copied it from pppd (http://ppp.samba.org/) and adapted it to lwIP. |
| Unfortunately, not many here know their way around it too well. Back in 2009, we took the effort to see which |
| version of pppd our code relates to and we're pretty much on 2.3.11 with some bugs from 2.4.x backported. |
| |
| Aside from simple code adaptions, there are some files that are different, however: |
| - chpms.c/.h are named chap_ms.c/.h in the original pppd 2.3.11 sources |
| - pap.c/.h are named upap.c/.h in the original pppd 2.3.11 sources |
| - randm.c is a random generator not included in the original pppd |
| - magic.c does not use the C library's random functions, but uses randm.c instead |
| - vj.c/.h is an implementation of the Van Jacobson header compression algorithm adapted to lwIP pbufs, |
| probably copied from one of the vjcompress.c files from pppd. |
| - ppp.c, ppp.h and ppp_impl.h contain the adaption from pppd to lwIP. This is the "OS"-dependent part like there |
| is an implementation for linux, xBSD etc. in the pppd sources. |
| - ppp_oe.c is Marc Boucher's implementation based on NetBSD's if_pppoe.c |
| |
| There is of course potential for bugs in it, but when analyzing of reporting bugs, it is strongly encouraged to |
| compare the code in question to pppd 2.3.11 (our basis) and newer versions (perhaps it's already fixed?) and to |
| share this knowledge with us when reporting a bug. |
