https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D203585 --- Comment #5 from commit-hook@freebsd.org --- A commit references this bug: Author: cy Date: Fri Jul 12 02:14:07 UTC 2019 New revision: 349931 URL: https://svnweb.freebsd.org/changeset/base/349931 Log: MFC r349927, r349929: r349927: Resolve IPv6 checksum errors with stateful inspection. According to PR/203585 this appears to have been broken by r235959, which predates the ipfilter 5.1.2 import into FreeBSD. The IPv6 checksum calculation is incorrect. To resolve this we call in6_cksum() to do the the heavy lifting for us, through a new function ipf_pcksum6(). Should we need to revisit this area again, a DTrace probe is added to aid with future debugging. Plus whitespace adjustments (r348989). PR: 203275, 203585 Differential Revision: https://reviews.freebsd.org/D20583 r349929: Move the new ipf_pcksum6() function from ip_fil_freebsd.c to fil.c. The reason for this is that ipftest(8), which still works on FreeBSD-11, fails to link to it, breaking stable/11 builds. ipftest(8) was broken (segfault) sometime during the FreeBSD-12 cycle. glebius@ suggested we disable building it until I can get around to fixing it. Hence this was not caught in -current. The intention is to fix ipftest(8) as it is used by the netbsd-tests (imported by ngie@ many moons ago) for regression testing.
