However, if `sc->sc_sync_if == NULL` we return without releasing the lock, and leak the lock, causing later deadlocks. Ensure we always release the bucket lock when we exit pfsync_defer_tmo() PR: 268246 MFC after: 1 week Sponsored by: Rubicon Communications, LLC (Netgate) sys/netpfil/pf/if_pfsync.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) -- You are receiving this mail because: You are the assignee for the bug.
