https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D254816 Rick Macklem <rmacklem@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Assignee|bugs@FreeBSD.org |rmacklem@FreeBSD.org Status|New |Open CC| |freqlabs@FreeBSD.org --- Comment #1 from Rick Macklem <rmacklem@FreeBSD.org> --- During recent testing of a Linux client NFSv4.1 mount to a FreeBSD server, breakage of both client and server was observed after a network partitioning between them. The FreeBSD server did not reply to a retried RPC using the session's cached reply as it should. The Linux client sometimes advances the sequence# for the session slot by 2 instead of 1. The attached patches alleviate the above problems and should be applied to all NFS servers handling NFSv4 mounts. Fortunately, network partitioning should be a rare event and the patches are only needed when that happens. --=20 You are receiving this mail because: You are the assignee for the bug.=
