The branch main has been updated by jhb: URL: https://cgit.FreeBSD.org/src/commit/?id=d00c20882f88877884b73fa9ec86b3cafeda4e42 commit d00c20882f88877884b73fa9ec86b3cafeda4e42 Author: John Baldwin <jhb@FreeBSD.org> AuthorDate: 2022-11-30 22:38:51 +0000 Commit: John Baldwin <jhb@FreeBSD.org> CommitDate: 2022-11-30 22:38:51 +0000 udp[6]_multi_input: Don't unlock freed inp. If udp[6]_append() returns non-zero, it is because the inp has gone away (inpcbrele_rlocked returned 1 after running the tunnel function).
