Modified files:
sys/net bpf.c
Log:
Adjust descriptor locking to tell the kqueue subsystem that our descriptor is
already locked. The reason to do this is to avoid two lock+unlock operations
in a row. We need the lock here to serialize access to bd_pid for stats
collection purposes.
Drop the locks all together on detach, as they will be picked up by
knlist_remove.
This should fix a failed locking assertion when kqueue is being used with bpf
descriptors.
