https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D204005 --- Comment #3 from commit-hook@freebsd.org --- A commit references this bug: Author: kp Date: Wed Aug 17 15:14:21 UTC 2016 New revision: 304293 URL: https://svnweb.freebsd.org/changeset/base/304293 Log: MFC r289932, r289940: PF_ANEQ() macro will in most situations returns TRUE comparing two identi= cal IPv4 packets (when it should return FALSE). It happens because PF_ANEQ() doesn't stop if first 32 bits of IPv4 packets are equal and starts to check next = 3*32 bits (like for IPv6 packet). Those bits containt some garbage and in resu= lt PF_ANEQ() wrongly returns TRUE. Fix: Check if packet is of AF_INET type and if it is then compare only fi= rst 32 bits of data.
