Author: eri Date: Mon Jul 4 17:43:04 2011 New Revision: 223765 URL: http://svn.freebsd.org/changeset/base/223765 Log: pf(4) tags now store the state key but tcp_respond tries to reuse a mbuf as an optimization. This makes pf find the wrong state and cause errors reported with state mismatches. Clear the cached state link on the pf(4) tag to avoid the state mismatches.
