RHBA-2012:0326 - Bug Fix Advisory

Topic

An updated strace package that fixes one bug is now available for Red Hat
Enterprise Linux 5.

Description

The strace program intercepts and records the system calls called and received
by a running process. It can print a record of each system call, its arguments
and its return value. The strace utility is useful for diagnosing, debugging and
instructional purposes.

This update fixes the following bug:

• The strace utility did not properly track switches between 32-bit and 64-bit

process execution domains (so called "personalities") when tracing multiple
processes with multiple "personalities". This caused strace to output the wrong
system call names and arguments for the traced processes. This update corrects
personality tracking in strace so that it now prints system call names and
arguments as expected. (BZ#788666)

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

relevant to your system have been applied.
