RHBA-2004:338 - Bug Fix Advisory
Synopsis
Updated strace package
Type/Severity
Bug Fix Advisory
Topic
An updated strace package that fixes several minor bugs and adds some small
enhancements are now available.
Description
The strace program intercepts and records the system calls and the signals
that are received by processes. Strace is useful for diagnosing problems
and debugging, as well as for instructional purposes.
The following bugs have been fixed:
- ioctl command values were recognized and their proepr names shown
- previously misprinted names
- output for the quotactl system call showed incorrect values
- sched_setaffinity and sched_getaffinity system calls
On the AMD64 platform, strace is able to trace both native 64-bit programs
and 32-bit programs. Previous versions had a bug that prevented
showing system call information for 32-bit programs. This has been corrected.
The following enchancements have been added:
- strace now recognizes sched_* system calls
- strace now indicates if it dumped a core file when a traced process dies
with a signal
Users of strace should install these updated packages, which resolve these
issues.
Solution
Before applying this update, make sure all previously released errata
relevant to your system have been applied.
To update all RPMs for your particular architecture, run:
rpm -Fvh [filenames]
where [filenames] is a list of the RPMs you wish to upgrade. Only those
RPMs which are currently installed will be updated. Those RPMs which are
not installed but included in the list will not be updated. Note that you
can also use wildcards (*.rpm) if your current directory *only* contains the
desired RPMs.
Please note that this update is also available via Red Hat Network. Many
people find this an easier way to apply updates. To use Red Hat Network,
launch the Red Hat Update Agent with the following command:
up2date
This will start an interactive process that will result in the appropriate
RPMs being upgraded on your system.
If up2date fails to connect to Red Hat Network due to SSL
Certificate Errors, you need to install a version of the
up2date client with an updated certificate. The latest version of
up2date is available from the Red Hat FTP site and may also be
downloaded directly from the RHN website:
