nfs-utils bug fix and enhancement update

Type/Severity

Bug Fix Advisory

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 " 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.
