RHBA-2009:1468 - autofs bug fix update

Synopsis

autofs bug fix update

Type/Severity

Bug Fix Advisory

Topic

An updated autofs package that fixes two bugs is now available.

Description

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.

This updated package fixes the following two autofs bugs:

  • autofs was incorrectly using a non-thread-safe libxml2 function as though it was thread-safe. This sometimes resulted in autofs crashing. With this update the calls to xmlCleanupParser() and xmlInitParser() have been moved: these functions are now only called as autofs starts and exits, ensuring these libxml2 functions are not called more than once while autofs is running. (BZ#523188)

  • a recent correction related to autofs master map entry updating introduced a regression whereby it was possible to deadlock when requesting a map re-load when an entry in a direct map had been removed. This update adds a check that ensures such map re-load requests do not cause a deadlock. (BZ#525431)

All autofs users should install this updated package which addresses these issues.

Solution

Before applying this update, make sure that all previously-released errata relevant to your system have been applied.
