RHBA-2010:0174 - Bug Fix Advisory
Synopsis
strace bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated strace package that fixes two bugs is now available.
Description
The strace program intercepts and records the system calls called and
received by a running process. Strace can print a record of each system
call, its arguments and its return value.
This updated strace package fixes the following bugs:
- when an strace process was terminated by a signal while the tracee was
executing a fork or clone system call the tracee was forcefully terminated
instead of being cleanly detached. This update corrects this: tracees are
now cleanly detached as expected when an strace process is terminated in
the circumstance noted above. (BZ#558471)
- RHBA-2010:0047, the strace update released to address BZ#548363,
uncovered a race condition on Itanium-based systems. (See References below
for a link to this previous release.) The race condition presented when
strace attached to a process while said process was executing the execve
system call. With this update, strace now reliably detects this post-execve
trap and, consequently, avoids the race condition. (BZ#564364)
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
This update is available via the Red Hat Network. Details on how to
