Hi, I boned up and, when wireshark reported that a NFSv4 packet was incorrectly constructed, I changed the NFSv4 code the "fix" the problem. I found out recently (at a IETF NFSv4 testing event) that wireshark was buggy and the code was actually broken by the "fix". I have now corrected this in main, stable/14 and stable/13. (Commit 54c3aa02e926 in main.) However, FreeBSD 13.3 shipped with this broken. The bug only affects the NFSv4 server if delegations are enabled, which is not the default. As such, so long as "vfs.nfsd.issue_delegations == 0". you should be fine. rick ps: Since few enable delegations, I do not feel this needs an errata for FreeBSD 13.3. .
