mbr 2006-09-19 19:25:11 UTC FreeBSD src repository Modified files: sys/kern kern_proc.c Log: Fix races between tty.c and sessrele() / doenterpgrp() / leavepgrp(). The tty code is still under giant lock, but the session/pgrp release code just used proctree_locks. This explains why moving the proctree_lock in sys/kern/tty.c rev. 1.258 did fix the panics in our SMP systems. This should also fix some race panics with revoked ttys. Reviewed by: jhb MFC after: 1 week Revision Changes Path 1.241 +6 -0 src/sys/kern/kern_proc.c
