Oracle Enterprise Linux Release 5 Update 4

Oracle is pleased to announce the general availability of Enterprise Linux Release 5 Update 4 for x86 (32 bit) and x86_64
(64 Bit) architectures.

This update includes the following kernel/driver changes:

Bug Fixes added by Oracle

* Check to see if hypervisor supports memory reservation change
[orabug 7556514]
* Add entropy support to igb [orabug 7607479]
* Convert ENETUNREACH to ENOTCONN [orabug 7689332]
* Add xen pv/bonding netconsole support [orabug 6993043]
* Shrink zone patch [orabug 6086839]
* Fix aacraid not to reset during kexec [orabug 8516042]
* Fix failure of file creation from hpux client [orabug 7579314]

Fixes/Additions from the upstream distribution provider

* A new tunable parameter /proc/sys/vm/max_writeback_pages has been added
to the kernel, allowing system administrators to change the maximum
number of modified pages kupdate writes to disk per iteration each time
it runs. It defaults to 1024 or 4MB so that a maximum of 1024 pages get
written out by each iteration of kupdate.
* A new option (CONFIG_TASK_IO_ACCOUNTING=y) has been added to kernel to
assist in monitoring IO statistics per process.
* The rd_blocksize option in kernel's ramdisk driver is removed.
* This release adds the kernel version details to oops and panic output.
* The serial_reg.h file is included in the kernel_headers rpm.
* Functionality has been added to sysrq-t to display backtrace information
about running processes.
* This update increases the maximum length of the kernel key field from the
arbitrary 32 character length set in previous kernels to 255 characters.
* This update addresses the security concern arising from non-root users
being able to create device nodes on filesystems exported using NFSD
(Network File System daemon).
* Added code to produce a signature file that GRUB performs a checksum
against during the boot process.
* Added code to change the DSA key from 512 bit to 1024 bit for module
signing.
* Asymmetric Logical Unit Access (ALUA) support in device-mapper-multipath
has been updated, adding explicit ALUA support for Clariion storage.
* Added support for raw devices. the initscripts packages is updated to
add functionality of raw devices.
* The -fwrapv variable added to GCC CFLAGS in order to define wrapping
behavior.

Driver Updates

to version 2.0.8-k2. This update also enables GRO support for the ixgbe
driver.
* bnx2 driver updated to version 1.9.3
* tg3 driver updated to version 3.96.. This driver update adds support for
5785F and 50610M devices.
* cnic driver has been added, providing Internet Small Computer System
Interface (iSCSI) support for bnx2 network devices.
* bnx2x driver updated to version 1.48.105.
* bnx2i driver has been added, providing iSCSI support for bnx2x network
devices.

to load. The install ipv6 /bin/false line needs to be replaced with
options ipv6 "disable=1" for the module to load properly.

Storage
