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

The following portions of OpenFabrics Alliance Enterprise Distribution (OFED) have been updated to the upstream version 1.4.1-rc3

* Remote Direct Memory Access (RDMA) headers

to version 2.0.8-k2. This update also enables GRO support for the ixgbe
driver.

version 0.62.
* sky2 driver updated.
* enic driver updated to version 1.0.0.933.
* e1000e driver updated to the upstream version 1.0.2-k2.
* bonding driver updated to the latest upstream version. With this updated
driver, if IPv6 has been previously disabled (install ipv6 /bin/false
line in the /etc/modprobe.conf file) the bonding kernel module will fail
to load. The install ipv6 /bin/false line needs to be replaced with
options ipv6 "disable=1" for the module to load properly.

Storage

* bnx2 driver updated to support iSCSI .
* bnx2i version included in this release does not support IPv6
* md driver updated to provide support for bitmap merging.
* scsi driver includes the upstream scsi_dh_alua module which enables
explicit asymmetric logical unit access (ALUA) support with this release.
To utilize the scsi_dh_alua module when using dm-multipath, specify alua
as the hardware_handler type in multipah.conf.
* rdac_dev_list structure now includes md3000 and md3000i entries.
* resolved panic during iSCSI iBFT installations.
* cxgb3 driver updated to support iSCSI TOE devices ( cxgb3i driver
include doesnot support IPv6).
* new mpt2sas driver which supports the SAS-2 family of adapters from
LSI Logic.
* aacraid driver updated to version 1.1.5-2461.
* aic7xxx driver now features an increased maximum I/O size.
* cciss driver has been updated to include upstream fixes affecting memory
BAR discovery, the rebuild_lun_table and the MSA2012 scan thread.
* fnic driver updated to version 1.0.0.1039.
* ipr driver updated to support MSI-X interrupts.
* lpfc driver updated to version 8.2.0.48.
* MPT fusion driver updated to version 3.04.07rh v2.

Tuning the nscd name cache daemon

I've been playing a bit with the nscd now and want to share some tips related to tuning the nscd.conf file. To see how the DNS cache is doing, use nscd -g. nscd configuration: 0 server debug level 26m 57s server runtime 5 current number of threads 32 maximum number of threads 0 number of times clients had to wait yes paranoia mode enabled 3600 restart internal passwd cache: no cache is enabled [other zero output removed] group cache: no cache is enabled [other zero output removed] hosts cache: yes cache is enabled yes cache is persistent yes cache is shared 211 suggested size <==== 216064 total data pool size 1144 used data pool size 3600 seconds time to live for positive entries <==== 20 seconds time to live for negative entries

Preventing PuTTY timeouts

Just found a great tip to prevent timeouts of PuTTY sessions. I'm fine with timeouts by the host, but in our case the firewall kills sessions after 30 minutes of inactivity... When using PuTTY to ssh to your Linux/Unix servers, be sure to use the feature to send NULL packets to prevent a timeout. I've set it to once every 900 seconds, i.e. 15 minutes... See screenshot on the right.

Setting up SR-IOV in RHEL6 on PowerEdge servers

Dell Community : "RHEL 6 provides SR-IOV functionality on supported hardware which provides near native performance for virtualized guests. Single-Root I/O Virtualization (SR-IOV) specification, introduced by PCI-SIG details how a single PCIe device can be shared between various virtualization guests. Devices capable of SR-IOV functionality support multiple virtual functions on top of the physical function. Virtual Function is enabled in hardware as a light weight PCIe function. Operating System cannot discover this function as it does not respond to the PCI bus scan and requires support in the host’s driver. As in PCIe pass-through, a Virtual function of a SR-IOV capable card can be directly assigned to the guest operating system. A virtual function driver running in the guest manages this device."
