RHBA-2013:1714 - nfs-utils bug fix and enhancement update

Synopsis

nfs-utils bug fix and enhancement update

Type/Severity

Bug Fix Advisory (none)

Topic

Updated nfs-utils packages that fix several bugs and add various enhancements are now available.

Description

The nfs-utils packages provide a daemon for the kernel Network File System (NFS) server and related tools such as the mount.nfs, umount.nfs, and showmount.

• When the "Background", "Foreground" or "timeo" options were set in multiple sections of the nfsmount.conf configuration file, each of those options were incorrectly present in the resulting parsed values. This update changes this behavior so that the first instance of either option overrides any previous ones.

In addition, configuration file options could have been incorrectly passed to the mount syscall from sections that were not relevant to the options that were being performed. The parser has been made more strict so that each option can appear at most four times: once for the system section, once for the server-specific section, once for the mount-specific section, and once for the command line mount options. (BZ#889272)

• Prior to this update, running "nfsstat -s -o rpc" command produced output with incorrect labels in a table header. With this update, the underlying source code has been adapted to make sure that all columns now have the correct name. (BZ#890146)

• Starting the nfs service resulted in the following output:

  Stopping RPC idmapd: [ OK ] Starting RPC idmapd: [ OK ]

Although the sequence of events of having to first stop and then start the RPC idmapd service was previously necessary, the current init scripts do not require this behavior. This has been corrected so that starting the nfs service now simply results in a single "Starting RPC idmapd" status display. (BZ#892235)

• When running sm-notify, specifying the "-v <ip_address>" or "-v " option did not work correctly after the nfs-utils packages were updated to version 1.2.2, which was the first version that included support for IPv6. This update corrects the address handling logic so that specifying a hostname, IPv4 or IPv6 IP address with the '-v' option works as expected. (BZ#950324)

• The nfs(5) manual page contained incorrect information about the "retrans=n" option, by which specifies the number of times an NFS client will retry a request before it attempts a further recovery action. This information has been corrected and now specifies the number of attempts by protocol type. The man page correction for the "retrans=n" option is:

  The number of times the NFS client retries a request before it attempts further recovery action. If the retrans option is not specified, the NFS client tries each request three times with mounts using UDP and two times with mounts using TCP.

(BZ#952560)

Users of nfs-utils are advised to upgrade to these updated packages, which fix these bugs and add various enhancements.
