https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=200330 --- Comment #12 from commit-hook@freebsd.org --- A commit references this bug: Author: kp Date: Wed Jun 10 13:44:04 UTC 2015 New revision: 284222 URL: https://svnweb.freebsd.org/changeset/base/284222 Log: pf: address family must be set when creating a pf_fragment Fix a panic when handling fragmented ip4 packets with 'drop-ovl' set. In that scenario we take a different branch in pf_normalize_ip(), taking us to pf_fragcache() (rather than pf_reassemble()). In pf_fragcache() we create a pf_fragment, but do not set the address family. This leads to a panic when we try to insert that into pf_frag_tree because pf_addr_cmp(), which is used to compare the pf_fragments doesn't know what to do if the address family is not set. Simply ensure that the address family is set correctly (always AF_INET in this path).
