RHBA-2010:0047 - Bug Fix Advisory
Synopsis
strace bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Lightspeed patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated strace package that fixes a bug when tracing a program that
blocks the SIGTRAP signal 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 bug:
- the kernel does not send SIGTRAP notifications to strace after an
execve system call finishes. Consequently, when "strace -f" was executed
against a program that blocked the SIGTRAP signal and subsequently called
execve, strace sent a "[preattached child 0 of 12166 in weird state!]"
message to STD OUT and hung. With this update, strace now checks for this
situation and re-synchronizes with system call notifications when
necessary. Note: this problem only presents on Itanium-based systems
(BZ#548363)
All strace users are advised to upgrade to this updated package, which
resolves this issue.
Solution
Before applying this update, make sure that all previously-released
errata relevant to your system have been applied.
