The branch main has been updated by pouria: URL: https://cgit.FreeBSD.org/src/commit/?id=caaa7a07fed4a16e753c0064482c0eaa0900607b commit caaa7a07fed4a16e753c0064482c0eaa0900607b Author: Ricardo Branco <rbranco@suse.de> AuthorDate: 2026-04-12 14:08:38 +0000 Commit: Pouria Mousavizadeh Tehrani <pouria@FreeBSD.org> CommitDate: 2026-04-17 07:22:39 +0000 linux: Support IPPROTO_RAW socket option translation Handle Linux IPPROTO_RAW socket options in the Linuxulator for both getsockopt(2) and setsockopt(2). Detect the socket family and remap the level to IPPROTO_IPV6 for AF_INET6, reusing the existing option translators. This fixes IPV6_CHECKSUM for IPv6 raw sockets, which Linux programs set at level IPPROTO_RAW rather than IPPROTO_IPV6.
