RHBA-2012:0206 - Bug Fix Advisory

Topic

An updated lsof package that fixes two bugs and adds two enhancements is now
available for Red Hat Enterprise Linux 5.

Description

The lsof (LiSt Open Files) package provides a utility to list information about
files that are open and running on Linux and UNIX systems.

This update fixes the following bugs:

• 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. This update modifies the %changelog section of the underlying
code. Now, the -w option successfully suppresses warning messages. (BZ#513613)

• 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. This update allows multiple NFS clients
to share superblocks. Now, lsof reports the correct server locations of mounted
folders. (BZ#705424)

In addition, this update adds the following enhancements:

• This update adds offset support to report file offset of opened files.

(BZ#582672)

• This 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.
(BZ#733684)

All users of lsof are advised to upgrade to this updated package, which fixes
these bugs and adds these enhancements.

Solution

Before applying this update, make sure all previously-released errata relevant
to your system have been applied.

This update is available via the Red Hat Network. Details on how to use the Red
Hat Network to apply this update are available at
