RHSA-2010:0178: Important Red Hat Enterprise Linux 5.5 kernel security and bug fix update
OLTP-type runs regressed by 0.5% due to the additional overhead in the aio_complete() code
path.
This update uses a bit in ki_flags to address this problem.
• Fix possible inode corruption on unlock.
• xfs: Fix fallocate error return sign.
When issuing an fallocate call on xfs which results in insufficient space to complete, XFS returns
"28" instead of "ENOSPC" - xfs uses positive errnos internally, and flips them before returning, but in
this case it was missed.
This update ensures the error number is inverted before being returned.
• Skip inodes without pages to free in drop_pagecache_sb().
• Fix soft lockup problem with dcache_lock.
• ext3: Replace lock_super with explicit resize lock.
A problem was found where performing an online resize of an ext3 filesystem would fail. This update
cross-ports a change developed for ext4 to address a similar problem.
• Update MPT fusion 3.4.13rh
The mtp base driver for devices using LSI Fusion MPT firmware has been updated to version
3.4.13rh. This update fixes many issues, most notably:
• The serial attached SCSI (SAS) topology scan has been restructured, adding expander, link
status and host bus adapter (HBA) events.
• Intermittent issues caused by SAS cable removal and reinsertion have been fixed.
• An issue where SATA devices received different SAS addresses has been fixed.
• The device firmware now reports the queue full event to the driver and the driver handles the
queue full event using the SCSI mid-layer.
• Update MPT2SAS to 02.101.00.00
The mpt2sas driver that supports the SAS-2 family of adapters from LSI has been updated to
version 02.101.00.00. This update fixes many issues, most notably:
• Sanity checks have been added when volumes are added and removed, ignoring events for
foreign volumes.
• The driver is now legacy I/O port free.
• An issue that may have resulted in a kernel OOPS at hibernation or resume has been fixed.
• Fix online resize bug while using resize2fs
• ENOSPC during fsstress leads to filesystem corruption on ext2, ext3, and ext4
• Bring putpubfh handling inline with upstream
