5.210. nfs-utils

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

Bug Fixes

BZ#737990
Prior to this update, the nfs(5) man page contained incorrect information on the Transmission Control Protocol (TCP) retries. This update modifies the man page and describes more accurately how the TCP time out code works.
BZ#740472
Prior to this update, the "nfs_rewrite_pmap_mount_options()" function did not interrupt RPC timeouts as expected. As a consequence, mounts that used the "-o bg" and "vers=" options did not retry but failed when the server was down. This update modifies the underlying code to allow mounts to retry when the server is down.
BZ#751089
Prior to this update, the rpc.idmapd daemon handled the "SIGUSR*" signal incorrectly. As a consequence, idmapd could, under certain circumstances, close without an error message. This update modifies the underlying code to process the "SIGUSR*" signal as expected.
BZ#758000
Prior to this update, mount points could not be unmounted when the path contained multiple slash characters. This update modifies the "umount" paths so that the mount point can now be unmounted as expected.
BZ#772543
Prior to this update, nfs-utils used the wrong nfs lock file. As a consequence, the "status nfsd" command did not return the correct status. This update modifies the startup script to use the "/var/lock/subsys/nfsd" file as the nfs lock file. Now the correct nfsd status is returned.
BZ#772619
Prior to this update, NFS ID Mapping could redirect Unicode characters using umlaut diacritics (ö, ä, ü) in group names to the group "nobody". This update deactivates the Unicode characters check.
BZ#787970
Prior to this update, the name mapping daemon idmapd failed to decode group names that contained spaces. This update modifies the character size check for decoding the octal encoded value. Now, group names with spaces are decoded as expected.
BZ#800335
Prior to this update, concurrent executions of the "exportfs" command could, under certain circumstances, cause conflicts when updating the etab file. As a consequence, not all exports were successful. This update modifies the exportfs script to allow for concurrent executions.
BZ#801085
Prior to this update, symlinks mounted with NFS could not be unmounted. This update modifies the underlying code so that symlinks are now exported as expected.
BZ#803946
Prior to this update, the nfsd daemon was started before the mountd daemon and nfsd could not validate file handles with mountd. The NFS client received an "ESTALE" error and client applications failed if an existing client sent requests to the NFS server when nfsd was started. This update changes the startup order of the daemons so that nfsd can use the mountd daemon.
BZ#816149
Prior to this update, the preinstall scriptlet could fail to change the default group ID for nfsnobody. This update modifies the preinstall scriptlet and the default group ID is changed after the nfs-utils upgrade as expected.
BZ#816162
Prior to this update, mounting a subdirectory of non-user accounts could, under certain circumstances, fail. This update modifies the underlying code ensure that also the parent directory of the pseudo exports have root squashing disabled. Now, subdirectories of non-user accounts can be successfully mounted.
All users of nfs-utils are advised to upgrade to these updated packages, which fix these bugs.
