autofs bug fix and enhancement update

Bug Fix Advisory

Topic

An updated autofs package that fixes several bugs and adds one enhancement is
now available for Red Hat Enterprise Linux 5.

Description

The autofs utility controls the operation of the automount daemon. The automount
daemon automatically mounts and unmounts file systems.

This update fixes the following bugs:

• Previously, autofs submounts incorrectly handled shutdown synchronization and
  lock restrictions. As a consequence, automount could be unresponsive when
  submounts expired. With this update, the submount shuts down only after the
  states ST_SHUTDOWN, ST_SHUTDOWN_PENDING, and ST_SHUTDOWN_FORCE, or when the
  state changes to ST_READY. (BZ#655685)
  
• Previously, automount did not correctly parse unmatched brackets in
  map entry server names. As a consequence, the sanity check for host
  names in these map entries could fail. Now, unmatched brackets in server
  names result in a syntax error being reported and the check no longer
  fails. (BZ#692814)
  
• Previously, the automount logged confusing error messages when syntax errors
  occurred in map entry locations. This update modifies these messages and
  displays more informative messages were possible. (BZ#700142)
  
• Previously, LDAP servers did not correctly return an opaque cookie to check
  for additional results when getting paged results from the server on 64-bit
  PowerPC and IBM System z platforms due to slightly different criteria for
  deciding if there are more results. As a consequence, the autofs internal
  functions did not detect when paged result sets were not supported. This update
  modifies the underlying source code so that autofs now correctly detects whether
  the paged results are updated. (BZ#700896)
  
• Previously, an incorrect check for the presence of additional addresses for a
  host led to the IP address being used for mounting instead of the host name. As
  a consequence the IP address was displayed instead of the host name when listing
  system mounts, even when the host had only a single address. This update
  modifies the check so that the IP address is used only if a host has multiple IP
  addresses. (BZ#725536)
  
• Previously, incorrect identification of the map entry source caused a failure
  during the key lookup. As a consequence, map lookups for an automount, where a a
  key was present in a file map and the same key was also found in an included
  map, failed if the file map entry was removed and a lookup was performed before
  a re-load is issued. This update modifies the key lookup code and the lookup
  works now as expected. (BZ#731514, BZ#732333)
  
• Previously, automount could become unresponsive when reloading a master map
  that included a combination of direct and indirect maps due to incorrect lock
  ordering. This update corrects the logic used to determine if the lookup needs
  to continue into included maps. (BZ#732332)
  
• Previously, map entries were always mounted using proximity and response time
  instead of bind mounting when adding a random selection of a host if the mount
  was local. This update modifies this behavior and also adds the "nobind" option
  to allow the previous behavior to be forced if needed. (BZ#734675)
  
• Previously, the map key lookup mechanism did not find keys in an included
  multi-mount map entry. This update modifies the lookup mechanism so that keys in
  multi-mount map entries are now found correctly. (BZ#747020)
  
• Previously, the stack allocation function of the temporary work space was used
  within a loop in the function lookup_ghost(). As a consequence, a stack overflow
  could occur and automount then failed with a segmentation fault. This update
  corrects the allocation usage and the stack overflows no longer occurs.
  (BZ#759221)
  

This update also adds the following enhancement:

• With this update,the "--dumpmaps" option to dump maps has been added to dump
  in autofs. (BZ#732334)
  

All users of autofs are advised to upgrade to this updated package, which fixes
these bugs and adds this enhancement.
