The branch main has been updated by kp: URL: https://cgit.FreeBSD.org/src/commit/?id=0fe663b2a815dcb41431543940ec51408f418392 commit 0fe663b2a815dcb41431543940ec51408f418392 Author: Kristof Provost <kp@FreeBSD.org> AuthorDate: 2023-11-16 16:06:29 +0000 Commit: Kristof Provost <kp@FreeBSD.org> CommitDate: 2023-11-17 22:33:43 +0000 pf: always create multihomed states as floating When we create a new state for multihomed sctp connections (i.e. based on INIT/INIT_ACK or ASCONF parameters) we cannot know what interfaces we'll be seeing that traffic on. Make those states floating, irrespective of state policy.
