Ltrace; Rhba-2009:0380: Bug Fix Update - Red Hat ENTERPRISE LINUX 5.4 - TECHNICAL NOTES Manual

Chapter 1. Package Updates
Updated lksctp-tools packages that resolve several issues are now available.
These packages are intended to supplement the Stream Control Transmission Protocol (SCTP)
reference implementation, which has been a part of the kernel since kernel version 2.5.36. For
more information on LKSCTP see the section titled "LKSCTP - Linux Kernel SCTP" in the README
file included in the package documentation. These packages contain the base runtime library and
command line tools.
These updated lksctp-tools packages fix a memory leak related to socket manipulation in the sctp
library. Also, explicit package version requirement was added into devel and doc sub-packages.
All users of lksctp-tools are advised to upgrade to these updated packages, which resolve this issue.

1.134.1. RHBA-2009:0380: bug fix update

Note
This update has already been released (prior to the GA of this release) as FASTRACK
RHBA-2009:0380
errata
An updated ltrace package that fixes various bugs is now available.
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 fixes for the following bugs:
• in some cases, when tracing the process that used fork system call, the kernel may have reported
certain events in the forked child even before it reported that the fork had occurred in the first place.
With this update, ltrace now anticipates this behavior, thus resolving the issue.
• on IBM System z machines, ltrace would crash when attempting to trace binaries that called
functions with five or more arguments. This has been fixed with this update and ltrace now works as
expected.
• when ltrace's '-o' option, which writes the output to a file, was used alongside the '-c' option, which
counts time and calls for each library call and reports a summary, ltrace sent the output to standard
error as usual instead of to the file designated on the command line. With this updated package,
ltrace sends the output to the designated file when it is called with the '-c' option, thus resolving this
issue.
• ltrace was not able to trace a binary that was called using the "exec" system call. With this update,
ltrace is now able to do so.
• the ltrace(1) man page incorrectly claimed that ltrace could not trace 64-bit binaries, and has been
corrected.
