RHBA-2007:0791 - Bug Fix Advisory

Topic

Updated kernel packages are now available as part of ongoing support
and maintenance of Red Hat Enterprise Linux version 4. This is the sixth
regular update to Red Hat Enterprise Linux 4.

Description

The Linux kernel handles the basic functions of the operating system.

New features introduced in this update include:

• The getcpu system call is now supported.
• /proc NUMA maps are now supported.
• Upgraded openib and openmpi to OFED 1.2 to provide InfiniBand support.
• madvise() now supports DONTFORK and DOFORK.
• Added /proc/sys/vm/drop_caches to clear pagecache and slabcache on demand.
• Removed upper value limit on /proc/sys/vm/max_queue_depth.
• The out of memory killer is designed to kill processes to recover memory

under very severe out of memory conditions. The out of memory killer can
now be disabled; as such, when an out of memory condition occurs, a kernel
panic will occur. To disable the out of memory killer, use the command echo
1 > /proc/sys/vm/panic_on_oom. Note that the out of memory killer is still
enabled by default.

• smaps functionality is now supported.
• Fixed an NFSv4 link bug that prevented i_nlink counts from updating properly.
• Updated CIFS client to version 1.48aRH.
• CONFIG_KPROBES is now enabled to provide Systemtap support.

• cxgb3: 1.0-ko
• arcmsr: 1.20.00.13
• netxen: 3.4.2

• acpi: PCI Root Bridge detection is now supported on HP rx5500 and HP

rx3600 platforms.

• Fixed a bug that prevented CPU frequency from scaling correctly on Conroe

and Broadwater chipsets.

• k8_edac driver now supports revision F processors.
• Kernel source now contains SMBus Device IDs for AMD and ATI SB600.
• MMCONFIG is now disabled by default on Intel Core 2 Duo platform.
• Oprofile now supports new Greyhound performance counter events.
• Packed stack layouts are now enabled on s390.
• 3592 tape encryption is now supported on s390.
• hypfs functionality is now supported on z/VM.
• Backported sysfs support on edac_mc.
• Added Hitachi HDS7250SASUN500G 0621KTAWSD to ncq blacklist.
• Added device IDs for ATI SB700.
