Oprofile; Rhba-2009:1322: Bug Fix And Enhancement Update; Pam; Rhba-2009:1358: Bug Fix And Enhancement Update - Red Hat ENTERPRISE LINUX 5.4 - TECHNICAL NOTES Manual

Chapter 1. Package Updates
• previously, the package description included a reference to a "freeswan enabled kernel". This
reference could have mislead users into thinking that Openswan required some special kernel,
when no such kernel exists. The reference has therefore been removed, eliminating the potential for
confusion. (BZ#487708
All users of openswan are advised to upgrade to this updated package, which resolves these issues.

1.167. oprofile

1.167.1. RHBA-2009:1322: bug fix and enhancement update

An updated oprofile package that adds support for the Java just-in-time runtime environment and fixes
an opcontrol bug is now available.
OProfile is a system-wide profiler for Linux systems. The profiling runs transparently in the background
and profile data can be collected at any time. OProfile makes use of the hardware performance
counters provided on many processors, and can use the Real Time Clock (RTC) for profiling on
processors without counters.
This update applies the following fixes:
• A bug that prevented opcontrol from displaying the 'Parameters' field whenever the --verbose
option was used is now fixed. In previous releases, opcontrol incorrectly used the do_init shell
function to initialize the VERBOSE variable (which contained the parameter list) to NULL. With
this update, opcontrol now uses the do_option shell function to initialize the VERBOSE variable.

(BZ#454969 )
• This update also provides support for collecting data on programs using Java runtime environments
that support jvmti (Java 1.5.0 and newer).
Users of oprofile are advised to upgrade to this update.

1.168. pam

1.168.1. RHBA-2009:1358: bug fix and enhancement update

Updated pam packages that fix several bugs and add various enhancements are now available for
Red Hat Enterprise Linux 5.
Pluggable Authentication Modules (PAM) provide a system whereby administrators can set up
authentication policies without having to recompile programs that handle authentication.
These updated pam packages provide fixes for the following bugs:
• when called from a screensaver running under a non-zero UserID, the pam_tally2 module could
repeatedly prompt for the user's password and then log the following error to syslog: "Error
opening /var/log/tallylog for update: Permission denied". With this update, pam_tally2 correctly
ignores failures to open the tallylog in this situation.
• the pam_access module unnecessarily attempted to resolve entries listed in the access.conf file
through DNS lookups, even if the service was not called from a network. The pam_access module
