duplicate dynamic discovery
by Fabian Mauchle 19 Oct '16

19 Oct '16

Symptom: radsecproxy is sometimes doing a dynamic discovery (and opens a new tls connection) even if there already is a working (dynamically discovered) connection for the given realm. Cause: Due to a bug in 'hasdynamicserver()' all information about dynamically discovered realms is removed when any dynamic connection gets closed. Please review the patch: https://code.nordu.net/?p=user/mauchle/radsecproxy.git;a=commitdiff;h=d768c… or pull here: https://git.nordu.net/user/mauchle/radsecproxy.git dup-dyndisc Best regards, Fabian -- SWITCH Fabian Mauchle, Network Engineer Werdstrasse 2, P.O.

PTHREAD_STACK_SIZE vs PTHREAD_STACK_MIN
by Kolbjørn Barmen 17 Oct '16

17 Oct '16

I was updating my set of Gentoo ebuilds for radsecproxy to 1.6.8, and wanted to use one of my PowerPC G4 Mini Mac systems with radsecproxy, but... minismurf # /usr/sbin/radsecproxy -v pthread_attr_setstacksize failed This led me to radsecproxy.c: 3406 if (pthread_attr_setstacksize(&pthread_attr, PTHREAD_STACK_SIZE)) 3407 debugx(1, DBG_ERR, "pthread_attr_setstacksize failed"); and found PTHREAD_STACK_SIZE defines in radsecproxy.h: 31 #define PTHREAD_STACK_SIZE 32768 With a bit of help, I found that my platform has minismurf # find /usr/include -type f | xargs egrep PTHREAD_STACK_MIN /usr/include/bits/local_lim.h:#define PTHREAD_STACK_MIN 131072 /usr/include/pthread.h: minimal size of the block must be PTHREAD_STACK_MIN. */ /usr/include/pthread.h: to be started. This size must never be less than PTHREAD_STACK_MIN minismurf # So, instead of simply defining PTHREAD_STACK_SIZE to a given size, the wanted value should probably be compared to PTHREAD_STACK_MIN first, and whichever value is largest is what PTHREAD_STACK_SIZE should be defined as. I attached a patch to radsecproxy.h that does this, "works for me [tm]" :) minismurf # /usr/sbin/radsecproxy -v radsecproxy revision 1.6.8 This binary was built with support for the following transports: UDP TCP TLS DTLS The patch seems to work fine from 1.6.3 (where this issue was introduced) up to 1.6.8, it also applies to 1.7-dev in git repo, but I stumbled on other issues there, so I have not tried building from git yet. -- Kolbjørn Barmen UNINETT, System og mellomvare

Mutual Authentication (TLS)
by Mofassir Ul Haque 07 Oct '16

07 Oct '16

Hi, Currently, radsecproxy supports mutual authentication by default i.e. both the Client and the Server certificate are validated at the time of TLS connection establishment. However, I want to only validate Server’s certificate. Is it possible to make changes to TLS Block (radsecproxy.conf) or to code to only do the validation of Server certificate's ? Any help will be greatly appreciated ! Thanks, Regards,
