RHBA-2013:0468 - nfs-utils bug fix update

Synopsis

nfs-utils bug fix update

Type/Severity

Bug Fix Advisory

Topic

Updated nfs-utils packages that fix several bugs are now available for Red Hat Enterprise Linux 6.

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.

This update fixes the following bugs:

  • Prior to this update, the rpc.mound daemon could cause NFS clients with already mounted NFSv3 shares to become suspended. This update modifies the underlying code to parse the IP address earlier. (BZ#797209)

  • Prior to this update, nfs-utils allowed stronger encryption types than Single DES. As a consequence, mounts to legacy servers that used the "-o sec=krb5" option failed. This update adds the -l flag to allow only Single DES. Now, secure mounts work with legacy servers as expected. (BZ#802469)

  • Prior to this update, NFS clients could fail to mount a share with the NFSv4 server if the the server had a large amount of exports to netgroups. As a consequence, NFSv4 mounts could become suspended. This update modifies the use_ipaddr case so that NFSv4 now mounts as expected. (BZ#815673)

  • Prior to this update, the NFS idmapper failed to initialize as expected. As a consequence, file permissions were incorrect. This update modifies the underlying code so that the idmapper initializes correctly. (BZ#849945)

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