RHBA-2011:0531 - Bug Fix Advisory

Topic

An updated upstart package that fixes various bugs is now available.

Description

upstart is an event-based replacement for the /sbin/init daemon that starts
tasks and services during boot, stops them during shut down, and supervises
them while the system is running.

This updated package fixes the following bugs:

• Calling /sbin/telinit resulted in a failed assertion on the 64-bit IBM

POWER Series because the value of telinit's "ret" variable was not
initialized when it was declared. The value of "ret" is now set explicitly
when the variable is declared. (BZ#648431)

• upstart sends jobs to the shell via a pipe represented by the

file descriptors under /proc/self/fd/ in the /proc filesystem. One of these
file descriptors was not closed, which resulted in a message about a file
descriptor leak when operating at run level 1. This file descriptor
is now closed correctly. (BZ#618995)

• upstart did not update the relevant entry in /var/run/utmp when a

mingetty session was terminated. This resulted in user process entries
being shown for terminals that were no longer active. The relevant entry
in /var/run/utmp is now correctly set to "DEAD_PROCESS" when a mingetty
session is terminated. (BZ#633216)

• The upstart package is now built with PIE and RELRO flags in order to

comply with Common Criteria specifications. (BZ#676002)

All users are advised to upgrade to this updated package, which resolves
these issues. Note that after installing this update, a system reboot is
required for the above changes to take effect.
