https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D203585 --- Comment #3 from commit-hook@freebsd.org --- A commit references this bug: Author: cy Date: Wed Jun 12 11:06:59 UTC 2019 New revision: 348987 URL: https://svnweb.freebsd.org/changeset/base/348987 Log: 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.
