I. Background The Network File System (NFS) allows a system to share directories and files with others over a network. By using this, users and programs can access files on remote systems almost as if they were local files. The rpc.rquotad utility is an rpc(3) server which returns quotas for a user of a local file system which is NFS-mounted onto a remote machine. II. Problem Description A change in rpc.rquotad made it send RQUOTA v2 requests instead of RQUOTA v1 requests. Some vendors would send RPC_PROGNOTREGISTERED ("Program Not Registered") response instead of the desired RPC_PROGVERSMISMATCH ("Program Version Mismatch") response, preventing the mechanism from working. III. Impact The quota(8) command will not be able obtain quota information for some NFS server vendors. IV. Workaround No workaround is available. Systems not using quotas on NFS mounted file systems are unaffected. V. Solution Upgrade your system to a supported FreeBSD stable or release / security branch (releng) dated after the correction date. Perform one of the following: 1) 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 2) To update your 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 https://security.FreeBSD.org/patches/EN-20:07/quotad.patch # fetch https://security.FreeBSD.org/patches/EN-20:07/quotad.patch.asc # gpg --verify quotad.patch.asc b) Apply the patch. Execute the following commands as root: # cd /usr/src # patch < /path/to/patch c) Recompile the operating system using buildworld and installworld as described in . Restart the applicable daemons, or reboot the system. VI. Correction details The following list contains the correction revision numbers for each affected branch. Branch/path Revision - ------------------------------------------------------------------------- stable/12/ r352575 releng/12.1/ r360148 stable/11/ r352576 releng/11.3/ r360148 - ------------------------------------------------------------------------- To see which files were modified by a particular revision, run the following command, replacing NNNNNN with the revision number, on a machine with Subversion installed: # svn diff -cNNNNNN --summarize svn://svn.freebsd.org/base Or visit the following URL, replacing NNNNNN with the revision number: VII.
