Restructuring of CVS head
by Alan DeKok 30 May '06

30 May '06

I'm going to move some of the header files in src/include around. Having almost everything in src/include/libradius.h is getting frustrating, and it's hard to track dependencies. My thoughts: - src/include/*.h is header for src/lib/*.c - updating hash table implementikon to avoid hash collisions - adding src/lib/packet.c There's a lock of socket & RADIUS packet list handling done in the server & radclient. This should be in library routines, to help with code re-use. - with support for 2-byte attributes, this becomes easier: http://lists.freeradius.org/pipermail/freeradius-users/2004-September/03622… i.e. a LOT easier. Now that there's an sql ippool module, the combination is starting to look interesting. Alan DeKok.

1.1.2 release?
by Peter Nixon 26 May '06

26 May '06

Hi Guys What is left to go before the 1.1.2 release? There are a number of issues building 1.1.1 on various newer linux releases, and added issues with 64bit which are fixed in the 1.1.x cvs. Is there any chance of a new point release soon? I am running the 1.1.x cvs branch in production for over a month now on a bunch of operon servers under pretty heavy load and no problems so far. Cheers -- Peter Nixon http://www.peternixon.net/ PGP Key: http://www.peternixon.net/public.asc

Authorization in EAP-TLS module
by Michal Prochazka 25 May '06

25 May '06

Hello, I sent here an small enhancement of EAP-TLS module. Now I would like to rewrite it to be more clear. Before I will do it, I would like to ask if this enhancement has a chance to be added into the freeradius? The think is that in authentication part of EAP-TLS will add new pair into the request which will contain whole certificate. I will write new authorization part of EAP-TLS which will work similar like the enhancement I've created with small changes: whole certificate will be sent into the environ of the script. After that the script can decide on any field in the certificate. -- Michal Prochazka // michalp(a)ics.muni.cz Supercomputing Center Brno Institute of Computer Science Masaryk University Botanicka 68a, 60200 Brno, CZ CESNET z.s.p.o.
