BTW, looks like there're no seqfaults/strange behavior anymore with static rc_handle with version from CVS. I have only very early results now, will continue to test it. -----Original Message----- From: freeradius-devel-bounces+alex=jajah.com@lists.freeradius.org [mailto:freeradius-devel-bounces+alex=jajah.com@lists.freeradius.org] On Behalf Of Alex Massover Sent: יום ב 01 מרץ 2010 15:37 To: FreeRadius developers mailing list Subject: RE: radiusclient thread-safety Hmmm.. Sorry again. This is not result of wrong configs. This is what I get when I do rc_handle per thread: rc_handle *rh; if ((rh = rc_read_config(RC_CONFIG_FILE)) == NULL) { ... } if (rc_read_dictionary(rh, rc_conf_str(rh, "dictionary")) != 0) {...} [...build send avpair...] rc_auth(); If I have a static rc_handle and call rc_read_config() and rc_read_dictionary() in parent there's no such problem. I'm even able to call rc_avpiar_log() just before rc_auth() and get correct dump of my avpiar.

Sorry, please ignore, I overwrote configs by mistake.

Hi,
Here's what I get with latest code from CVS:
Program terminated with signal 11, Segmentation fault. #0 0xb762fd19 in strncpy () from /lib/i686/cmov/libc.so.6 (gdb) bt #0 0xb762fd19 in strncpy () from /lib/i686/cmov/libc.so.6 #1 0xb61540f0 in rc_send_server () from /usr/lib/libfreeradius- client.so.2 #2 0xb6152c32 in rc_aaa () from /usr/lib/libfreeradius-client.so.2 #3 0xb6152ec4 in rc_auth () from /usr/lib/libfreeradius-client.so.2 #4 0xb616c52f in sendrad_exec_generic (chan=0x9477088, data=<value optimized out>, type=0) at app_sendradevent.c:212 #5 0x080f67c7 in pbx_exec () #6 0x080f76d0 in ??

And the strange thing is that sometimes (rarely) it works, exactly the same code.
Compiled with CFLAGS="-pthread -D_REENTRANT -fstack-protector-all"
Or

Hi,
I use radiusclient-ng code base, but freeradiusclient has exactly the same code, at least the latest release downloaded from here:
ftp://ftp.freeradius.org/pub/freeradius/freeradius-client- 1.1.6.tar.bz2
It's in lib/sendserver.c line 322 (there's only one FD_ISSET)
OK. Then try grabbing the latest version from CVS. It has a number of fixes.
