| Description: | The kernel packages contain the Linux kernel, the core of any Linux operating system.
Kernel Feature Support: iostat displays I/O performance for partitions I/O task accounting added to getrusage(), allowing comprehensive core statistics page cache pages count added to show_mem() output tux O_ATOMICLOOKUP flag removed from the open() system call: replaced with O_CLOEXEC the kernel now exports process limit information to /proc/[PID]/limits implement udp_poll() to reduce likelihood of false positives returned from select() the TCP_RTO_MIN parameter can now be configured to a maximum of 3000 milliseconds. This is configured using "ip route" update CIFS to version 1.50
Added Features: nfs.enable_ino64 boot command line parameter: enable and disable 32-bit inode numbers when using NFS tick "divider" kernel boot parameter: reduce CPU overhead, and increase efficiency at the cost of lowering timing accuracy /proc/sys/vm/nfs-writeback-lowmem-only tunable parameter: resolve NFS read performance /proc/sys/vm/write-mapped tunable option, allowing the option of faster NFS reads support for Large Receive Offload as a networking module core dump masking, allowing a core dump process to skip the shared memory segments of a process
Virtualization: para-virtualized network and block device drivers, to increase fully-virtualized guest performance support for more than three VNIF numbers per guest domain
Platform Support: AMD ATI SB800 SATA controller, AMD ATI SB600 and SB700 40-pin IDE cable 64-bit DMA support on AMD ATI SB700 PCI device IDs to support Intel ICH10 /dev/msr[0-n] device files powernow-k8 as a module SLB shadow buffer support for IBM POWER6 systems support for CPU frequencies greater than 32-bit on IBM POWER5, IBM POWER6 floating point load and store handler for IBM POWER6
Added Drivers and Updates: ixgbe 1.1.18, for the Intel 82598 10GB ethernet controller bnx2x 1.40.22, for network adapters on the Broadcom 5710 chipset dm-hp-sw 1.0.0, for HP Active/Standby zfcp version and bug fixes qdio to fix FCP/SCSI write I/O expiring on LPARs cio bug fixes eHEA latest upstream, and netdump and netconsole support ipr driver support for dual SAS RAID controllers correct CPU cache info and SATA support for Intel Tolapai i5000_edac support for Intel 5000 chipsets i3000_edac support for Intel 3000 and 3010 chipsets add i2c_piix4 module on 64-bit systems to support AMD ATI SB600, 700 and 800 i2c-i801 support for Intel Tolapai qla4xxx: 5.01.01-d2 to 5.01.02-d4-rhel4.7-00 qla2xxx: 8.01.07-d4 to 8.01.07-d4-rhel4.7-02 cciss: 2.6.16 to 2.6.20 mptfusion: 3.02.99.00rh to 3.12.19.00rh lpfc:0: 8.0.16.34 to 8.0.16.40 megaraid_sas: 00.00.03.13 to 00.00.03.18-rh1 stex: 3.0.0.1 to 3.6.0101.2 arcmsr: 1.20.00.13 to 1.20.00.15.rh4u7 aacraid: 1.1-5[2441] to 1.1.5[2455]
Miscellaneous Updates: OFED 1.3 support wacom driver to add support for Cintiq 20WSX, Wacom Intuos3 12x19, 12x12 and 4x6 tablets sata_svw driver to support Broadcom HT-1100 chipsets libata to un-blacklist Hitachi drives to enable NCQ ide driver allows command line option to disable ide drivers psmouse support for cortps protocol
These updated packages fix the following security issues:
NULL pointer access due to missing checks for terminal validity. (CVE-2008-2812, Moderate)
a security flaw was found in the Linux kernel Universal Disk Format file system. (CVE-2006-4145, Low)
