Chapter 4. Package Updates
An updated lsof package that fixes two bugs and adds two enhancements is now available for Red Hat
Enterprise Linux 5.
T he lsof (LiSt Open Files) package provides a utility to list information about files that are open and
running on Linux and UNIX systems.
Bug Fixes
BZ #513613
Prior to this update, the lsof utility ignored the -w option if both the -b and the -w options were
specified. As a consequence, lsof failed to suppress warning messages. T his update modifies
the %changelog section of the underlying code. Now, the -w option successfully suppresses
warning messages.
BZ #7054 24
Prior to this update, lsof could, under certain circumstances, report incorrect server locations of
mounted folders if multiple Network File System (NFS) shares from one host were mounted.
T his update allows multiple NFS clients to share superblocks. Now, lsof reports the correct
server locations of mounted folders.
Enhancements
BZ #582672
T his update adds offset support to report file offset of opened files.
BZ #733684
T his update adds the new option +|-e s to lsof which exempts file systems with the path name
"s" from being subjected to kernel function calls that can block.
All users of lsof are advised to upgrade to this updated package, which fixes these bugs and adds
these enhancements.
4.100. ltrace
4.100.1. RHBA-2011:1473 — ltrace bug fix update
An updated ltrace package that fixes various bugs is now available.
T he 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. T he ltrace utility can also intercept
and print system calls executed by the process.
Bug Fix
BZ #733216
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.
