https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D250499 --- Comment #4 from commit-hook@FreeBSD.org --- A commit references this bug: Author: tuexen Date: Mon Nov 30 10:58:07 UTC 2020 New revision: 368183 URL: https://svnweb.freebsd.org/changeset/base/368183 Log: MFC r367530: RFC 7323 specifies that: * TCP segments without timestamps should be dropped when support for the timestamp option has been negotiated. * TCP segments with timestamps should be processed normally if support for the timestamp option has not been negotiated. This patch enforces the above. Manually resolved merge conflicts. MFC 367891: Fix an issue I introuced in r367530: tcp_twcheck() can be called with to =3D=3D NULL for SYN segments. So don't assume tp !=3D NULL. Thanks to jhb@ for reporting and suggesting a fix. MFC r367946: Fix two occurences of a typo in a comment introduced in r367530. Thanks to lstewart@ for reporting them.
