RHBA-2010:0384 - Bug Fix Advisory
Synopsis
autofs bug fix update
Type/Severity
Bug Fix Advisory
Topic
An updated autofs package that fixes a bug 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 autofs bug:
- autofs would abort when using DIGEST-MD5 authentication under heavy
concurrent access. This was caused by autofs not providing the locking
functions required by the cyrus-sasl library. In addition the
cyrus-sasl library locking functions contained a race which sometimes
lead to a deadlock. This update adds the needed locking functions to
autofs and passes them to cyrus-sasl at initialization. The bug in the
cyrus-sasl library is fixed in cyrus-sasl-lib 2.1.22-5.el5.el5_4.3 and
later which is required for the update to install if cyrus-sasl is
also installed. (BZ#567537)
All autofs users are advised to upgrade to this updated package, which
resolves this issue.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
