Background - -The Network File System (NFS) allows a host to export some or all of -its file systems that can be any kind of file systems such like UFS, ZFS -etcetera, so that other hosts can access them over the network and mount -them as if they were on local disks. - -II. Problem Description - -In a configuration where two or more clients mount a ZFS file system over -NFSv4 from a FreeBSD server, if client1 caches a directory listing and a -file in the directory is renamed on client2, then client1 can end up in -a state where the cached but incorrect directory contents persists indefinitely -and is never updated. - -III. Impact - -When client2 renames a file or directory, client1 does not receive the -changed attributes and never does a READDIR to get the updated contents. -This could result in a client that has incorrect information about the -actual content of the mounted file system. - -IV. Workaround - -No workaround is available. - -V. Solution - -Perform one of the following: - -1) Upgrade your system to a supported FreeBSD stable or release / security -branch (releng) dated after the correction date. - -2) To update your system via a binary patch: - -Systems running a RELEASE version of FreeBSD on the i386 or amd64 -platforms can be updated via the freebsd-update(8) utility: - -# freebsd-update fetch -# freebsd-update install - -3) To update your present system via a source code patch: - -The following patches have been verified to apply to the applicable -FreeBSD release branches. - -a) Download the relevant patch from the location below, and verify the -detached PGP signature using your PGP utility. - -# fetch http://security.FreeBSD.org/patches/EN-14:12/zfs.patch -# fetch http://security.FreeBSD.org/patches/EN-14:12/zfs.patch.asc -# gpg --verify zfs.patch.asc - -b) Apply the patch. Execute the following commands as root: - -# cd /usr/src -# patch < /path/to/zfs.patch - -c) Recompile your kernel as described in -<URL:http://www.FreeBSD.org/handbook/kernelconfig.html> and reboot the -system. - -VI.
