5.11. autofs 5.11.1. RHBA-2012:1442 - autofs bug fix update Updated autofs packages that fix one bug are now available for Red Hat Enterprise Linux 6. The autofs utility controls the operation of the automount daemon. The automount daemon automatically mounts file systems when you use them and unmounts them when they are not busy. Bug Fix BZ# 870929 During the boot-up sequence, when the automount daemon was using an internal host map, automount terminated unexpectedly with a segmentation fault. This bug has been fixed and the crashes no longer occur in the described scenario. All users of autofs are advised to upgrade to these updated packages, which fix this bug. 5.11.2. RHBA-2012:0951 - autofs bug fix and enhancement update Updated autofs packages that fix several bugs and add an enhancement are now available for Red Hat Enterprise Linux 6. The autofs utility controls the operation of the automount daemon. The automount daemon automatically mounts file systems when you use them, and unmounts them when they are not busy. Bug Fixes BZ# 772946 A recent change to correct a problem with included map entry removal introduced a new problem with included map key look-up. The condition used in the patch was too broad and the map key lookup mechanism failed to find keys in an included multi-mount map entry. The condition has been modified so that keys in multi-mount map entries are now found correctly. BZ# 772356 A function that checks validity of a mount location was meant to check only for a small subset of map location errors. A recent improvement modification in error reporting inverted a logic test in this validating function. Consequently, the scope of the test was widened, which caused automount to report false-positive failures. With this update, the faulty logic test has been fixed and false-positive failures no longer occur. BZ# 790674 Previously, autofs submounts incorrectly handled shutdown synchronization and lock restrictions. As a consequence, automount could become unresponsive when submounts expired. With this update, the submount shuts down only after passing through the state ST_SHUTDOWN, ST_SHUTDOWN_PENDING, or ST_SHUTDOWN_FORCE, or when the state changes to ST_READY. BZ# 753964 Prior to this update, two IPv6 compatibility functions were erroneously not included in the autofs interface to the libtirpc library. This prevented the autofs IPv6 RPC code from working. With this update, the libtirpc interface code for autofs has been fixed. BZ# 782169 When using the legacy auto.net script for the hosts map, an error in the script for handling multiple occurrences of exports prevented the script from returning any of the exported paths. This bug has been fixed by modifying the script to select only a unique list of exports, thus eliminating duplicate exports. BZ# 787595 Due to changes to the mount.nfs utility to take advantage of the support for NFS mount options in the kernel, the RPC processing had moved from mount.nfs to the kernel. However, the kernel RPC had to wait for RPC requests to servers that were not available to time out, resulting in very slow interactive response when attempting an automount to a server that was not available. This update changes the autofs RPC code to detect this situation early and provide proper error messages as soon as possible. BZ# 760945 Previously, although the /net/ and /misc/ directories are exclusively used by the default /etc/auto.master utility, they were not specified in the autofs RPM package. As a result, the rpm utility reported them as not owned by any package. This update adds both these directories to the autofs spec file. BZ# 745527 Previously, the autofs init.d script failed to return proper usage messages if called with no arguments, or incorrect arguments. This bug has been fixed and the script now prints the usage information as expected. Enhancement BZ# 683523 Initial support for the System Security Services Daemon (SSSD) as a map source has been added to the autofs package. All autofs users are advised to upgrade to these updated packages, which fix these bugs and add this enhancement.
