RHBA-2011:0403 - Bug Fix Advisory

Topic

An updated autofs package that fixes one bug is now available for Red Hat
Enterprise Linux 6.

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 update fixes the following bug:

• Prior to this update, an attempt to restart the autofs service while a mounted

file system was in use caused the service to stop responding upon its startup.
This was due to inappropriate locking during the recursive reconstruction of
mount trees of pre-existing mounted multi-mount map entries. With this update,
the underlying source code has been adapted to avoid the deadlock during the
mount tree reconstruction, so that autofs now starts as expected. Additionally,
this update prevents autofs from occasionally terminating with a segmentation
fault upon a map entry lookup. (BZ#689754)

All users of autofs are advised to upgrade to this updated package, which fixes
this bug.

Solution

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

This update is available via Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
