| H A D | sleepqueue.9 | diff 201879 Fri Jan 08 23:56:01 MST 2010 attilio Introduce the new kernel thread called "deadlock resolver". While the name is pretentious, a good explanation of its targets is reported in this 17 months old presentation e-mail: http://lists.freebsd.org/pipermail/freebsd-arch/2008-August/008452.html In order to implement it, the sq_type in sleepqueues is mandatory and not only compiled along with INVARIANTS option. Additively, a new sleepqueue function, sleepq_type() is added, returning the type of the sleepqueue linked to a wchan. Three new sysctls are added in order to configure the thread: debug.deadlkres.slptime_threshold debug.deadlkres.blktime_threshold debug.deadlkres.sleepfreq rappresenting the thresholds for sleep and block time that will lead to a deadlock matching (when exceeded), while the sleepfreq rappresents the number of seconds between 2 consecutive thread runnings. In order to enable the deadlock resolver thread recompile your kernel with the option DEADLKRES.

| H A D | pf_norm.c | diff 285999 Wed Jul 29 04:39:39 MDT 2015 kp pf: Always initialise pf_fragment.fr_flags When we allocate the struct pf_fragment in pf_fillup_fragment() we forgot to initialise the fr_flags field. As a result we sometimes mistakenly thought the fragment to not be a buffered fragment. This resulted in panics because we'd end up freeing the pf_fragment but not removing it from V_pf_fragqueue (believing it to be part of V_pf_cachequeue). The next time we iterated V_pf_fragqueue we'd use a freed object and panic. While here also fix a pf_fragment use after free in pf_normalize_ip(). pf_reassemble() frees the pf_fragment, so we can't use it any more. PR: 201879, 201932 MFC after: 5 days |
