| H A D | rwlock_emul.c | diff 314251 Sat Feb 25 08:20:16 MST 2017 cy MFC r312787: Currently the fragment info is placed at the top of the linked list under a shared read lock. This patch attempts to upgrade the lock to an exclusive write lock. If the exclusive write lock fails to be obtained, the current fragment is not placed at the head of the list. This portion of the patch was inspired by NetBSD ip_frag.c r1.4 (which effectively removed the section of code that performed the reordering). The patch to sys/contrib/ipfilter/netinet/ip_compat.h adds the MUTEX_TRY_UPGRADE macro to support the patch to ip_frag.c. The patch to contrib/ipfilter/lib/rwlock_emul.c supports this patch by emulating the mutex in userspace when exercised by ipftest(1). Inspired by: NetBSD ip_frag.c r1.4 |
