RHBA-2009:1413 - Bug Fix Advisory

Topic

An updated e4fsprogs package that fixes a bug is now available.

Description

The e4fsprogs package contains a number of utilities for creating,
checking, modifying, and correcting inconsistencies in ext4 and ext4dev
file systems. e4fsprogs contains e4fsck (used to repair file system
inconsistencies after an unclean shutdown), mke4fs (used to initialize a
partition to contain an empty ext4 file system), tune4fs (used to modify
file system parameters), and most other core ext4fs file system utilities.

The e4fsprogs package has been upgrade to upstream version 1.41.5 for Red
Hat Enterprise Linux 5.4. This updated package contains several bug fixes
over the previous version.

Important: this package is now designed and intended to be installed
alongside the original e2fsprogs package in Red Hat Enterprise Linux. As
such, certain binaries in the e4fsprogs package have been given new names.
For example, the utility that checks ext4 file systems for consistency has
been renamed to "e4fsck", thus allowing the original "e2fsck" program from
the e2fsprogs package to coexist on the same system. (BZ#485316)

Notably, this updated e4fsprogs package includes a fix for the following
bug:

• invoking the "stats" command while at the "debuge4fs" prompt could cause

"debuge4fs" to segmentation fault due to a missing check to see whether the
file system was currently open. This has been fixed in this updated package
so that calling "stats" is now safe. (BZ#482894)

All users of e4fsprogs are advised to upgrade to this updated package,
which resolves this issue.
