Thanks. Tested, works (and I already got chided for my lack of faith). Uncrustify complained about whitespace conventions, so I've adjusted those (whitespace-only, no code changes), and the patch did not apply "as is" because Antonio changed a bit in dco_freebsd.h in the mean time so one line of diff context was different - trivial fix.
I tested this with the kernel patch in https://reviews.freebsd.org/D51468, on top of a 14.2-RELEASE-p4 kernel - v4/v4 float on an udp4 socket, v4/v4 and v6/v6 float on an udp6 dual-stack socket. Running an "old binary" on top of a "very new kernel" has a bit of risk - if a client floats, userland will see an "Unknown kernel notification 2" and kill the instance SIGTERM[soft,ovpn-dco: unknown reason] received, client-instance exiting this is somewhat unavoidable as userland depends on having the kernel constant available. So, for the sake of the archives - if you upgrade your FreeBSD and an OpenVPN server kills clients on float, upgrade your userland (old server + old kernel would not support float at all, and clients will just time out). Your patch has been applied to the master branch. commit b66b80b2ab73bb422826911b675798e6b789ef03 Author: Kristof Provost Date: Wed Jul 23 10:36:49 2025 +0200 dco: support float notifications on FreeBSD Signed-off-by: Kristof Provost <kprov...@netgate.com> Acked-by: Gert Doering <g...@greenie.muc.de> Message-Id: <20250723083816.71604-2-kprov...@netgate.com> URL: https://www.mail-archive.com/openvpn-devel@lists.sourceforge.net/msg32282.html Signed-off-by: Gert Doering <g...@greenie.muc.de> -- kind regards, Gert Doering _______________________________________________ Openvpn-devel mailing list Openvpn-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/openvpn-devel
