Chapter 1. Package Updates
236
All users of strace are advised to upgrade to this updated package, which resolves this issue.
1.211.2. RHBA-2009:0017: bug fix update
Note
This update has already been released (prior to the GA of this release) as errata
RHBA-2009:0017
1672
Updated strace packages that fix one bug are now available.
The strace program intercepts and records the system calls that are made and the signals that are
received by processes.
The following issue has been addressed:
• when a stopped process being examined by strace is killed, strace now reports the event correctly.
The prime example is a SIGKILL being sent to a traced process.
Users of strace should upgrade to these updated packages, which resolves this bug.
1.211.3. RHBA-2009:1317: bug fix update
An strace update that fixes several bugs is now available.
The strace program intercepts and records system calls issued and received by a running process.
Strace can print a record of each system call, its arguments and its return value.
With this update, strace is now upgraded to version 4.5.18. This applies several upstream bug fixes
and enhancements, including:
• An erroneous file locking instruction caused strace to incorrectly decode fcntl64() system call
parameters in 32-bit programs running on 64-bit systems. This release corrects the errant
file locking instruction, ensuring that fcntl64() system call parameters are decoded correctly.

BZ#471169

)
• A race condition made it possible for ptrace_do_wait() to prematurely conclude an exit report of a
terminated process before the kill signal could set the proper exit code. Whenever this occurred,
strace could leave out details of the kill signal in its exit report. This update applies a workaround
that instructs strace to check SIGKILL queues before issuing an exit report. (
BZ#472053
1674
)
• When strace was executed with the -f option on a multi-threaded process, it was possible for some
threads in that process to stop. This could prevent the traced process from terminating. This was
caused by a bug that prevented some threads in a traced multi-threaded process from receiving
ample CPU time. This update provides functions for providing CPU time to threads in traced multi-
threaded processes, along with instructions for resuming halted threads. (
BZ#478419

Users of strace should apply this update.
