The branch main has been updated by rmacklem: URL: https://cgit.FreeBSD.org/src/commit/?id=33d0be8a923a840ec0724d50815890c5ffe0e884 commit 33d0be8a923a840ec0724d50815890c5ffe0e884 Author: Rick Macklem <rmacklem@FreeBSD.org> AuthorDate: 2021-12-01 21:46:41 +0000 Commit: Rick Macklem <rmacklem@FreeBSD.org> CommitDate: 2021-12-01 21:46:41 +0000 nfsd: Do not try to cache a reply for NFSERR_BADSLOT When nfsrv_checksequence() replies NFSERR_BADSLOT, the value of nd_slotid is not valid. As such, the reply cannot be cached in the session. Do not set ND_HASSEQUENCE for this case.
