Hello, I made a patch that adds fast locking mechanisms instead of seq file for freeradius-client. This patch is based on putting the sequence number in the shared memory. Two approaches used to do a mutual exclusion for shared memory: a) GCC builtin atomic memory access (only on Intel) b) POSIX named semaphore Fallback: c) If nothing of the above available it fallbacks to a sequence file locks. Originally I did it against radiusclient-ng, but looks that freeradius-client is a correct place. The patch works for freeradius-client 1.1.6 as well. Here's a patch and more detailed description: http://developer.berlios.de/patch/?func=detailpatch&patch_id=2810&group_id=1... -- Best Regards, Alex Massover VoIP R&D TL Jajah Inc.
