RHBA-2011:0702 - e2fsprogs bug fix and enhancement update

Synopsis

e2fsprogs bug fix and enhancement update

Type/Severity

Bug Fix Advisory

Topic

Updated e2fsprogs packages that fix several bugs and add various enhancements are now available.

Description

The e2fsprogs packages contain a number of utilities that create, check, modify, and correct inconsistencies in second extended (ext2) file systems. This includes e2fsck (which repairs file system inconsistencies after an unclean shut down), mke2fs (which initializes a partition to contain an empty ext2 file system), tune2fs (which modifies file system parameters), and most of the other core ext2fs file system utilities.

This update fixes the following bugs:

• The e2fsprogs package appeared to contain several regressions because of a number of type-punning issues caused by flags used during the process of building Red Hat Enterprise Linux. Additionally, e2fsprogs had a dependency on libcom_err that was not linked to a specific version of libcom_err. A specific version has been defined to prevent interoperability issues between packages. (BZ#599338)

• The badblocks command aborted with the error "badblocks: File too large while trying to determine device size" when attempting to run on a 16TB file system. This was caused by a bug in the badblocks command, which this bug fixes, resolving the issue. (BZ#631593)

• A device that is exactly 16T in size was too large to be opened by the resize2fs utility and attempting to resize some large file systems may remove the resize inode feature if no reserved blocks were left after the operation. This resulted in resize2fs to fail on that device, and resizing a file system close to 16T could remove the resize inode, making further resizing impossible. This patch treats 16T file systems as 16T - 4k, as mkfs does, allowing them to be manipulated by the resize2fs utility, resulting in ext3 and ext4 file systems now able to be resized on devices exactly 16T in size. Do not, however, remove resize inode even if 0 reserved blocks remain, so that subsequent downward resizes are still possible. (BZ#654093)

• When a value greater than INT_MAX (2147483647) was specified as the argument to mke2fs -G , the command did not complete. This was because the argument for int_log2() was "int", therefore when a value exceeding INT_MAX is specified for the -G option, the value of "arg" overflows. Also, e2fsprogs only supports 2^32 block file systems so asking for anything greater cannot be honored. Therefore, this patch rejects a number that overflows, and restricts it to INT_MAX+1 so the result does not wrap. This resolves the issue. (BZ#643390)

• The filefrag command occasionally returned an incorrect number of extensions, returning 0 instead of 1 when using the -v extension. In this patch, special-casing the number of extensions returned in verbose mode and skipping the printing of the header for columns resolves this issue. (BZ#653234)

All users are advised to upgrade to these updated packages, which resolve these issues.
