RHBA-2011:1473 - Bug Fix Advisory
Synopsis
ltrace bug fix update
Type/Severity
Bug Fix Advisory
Red Hat Insights patch analysis
Identify and remediate systems affected by this advisory.
Topic
An updated ltrace package that fixes various bugs is now available.
Description
The ltrace utility is a debugging program that runs a specified command until
the command exits. While the command is executing, ltrace intercepts and
records both the dynamic library calls called by the executed process and the
signals received by the executed process. The ltrace utility can also intercept
and print system calls executed by the process.
This updated ltrace package includes a fix for the following bug:
- When tracing a process with many threads, the traced process would very likely
be killed as the threads ran into breakpoins that wouldn't be handled by ltrace.
With this update, ltrace attaches to the newly created threads, and carefully
handles the breakpoints so that tracing events are not missed.
Note: when ltrace attached to a running process, that process could have been
detached with the instruction pointer pointed mid-instruction, or with pending
events, which would kill the process. This update improves the detach logic so
that the process is left in a consistent state before detaching. (BZ#733216)
All users of ltrace are advised to upgrade to this updated package, which
resolves these issues.
Solution
Before applying this update, make sure all previously-released errata
relevant to your system have been applied.
