Red Hat ENTERPRISE LINUX 5.4 - TECHNICAL NOTES Manual page 139

• the Linux kernel implementation of the Network File System (NFS) did not properly initialize the file
name limit in the nfs_server data structure. This flaw could possibly lead to a denial of service on a
client mounting an NFS share.
This update also fixes the following bugs:
• the enic driver (Cisco 10G Ethernet) did not operate under virtualization.
• network interfaces using the IBM eHEA Ethernet device driver could not be successfully configured
under low-memory conditions.
• bonding with the "arp_validate=3" option may have prevented fail overs.
• when running under virtualization, the acpi-cpufreq module wrote "Domain attempted WRMSR"
errors to the dmesg log.
• NFS clients may have experienced deadlocks during unmount.
• the ixgbe driver double counted the number of received bytes and packets.
• the Wacom Intuos3 Lens Cursor device did not work correctly with the Wacom Intuos3 12x12 tablet.

(BZ#489460 )
• on the Itanium® architecture, nanosleep() caused commands which used it, such as sleep and
usleep, to sleep for one second more than expected.
• a panic and corruption of slab cache data structures occurred on 64-bit PowerPC systems when
clvmd was running. (BZ#491677
• the NONSTOP_TSC feature did not perform correctly on the Intel® microarchitecture (Nehalem)
when running in 32-bit mode.
• keyboards may not have functioned on IBM eServer System p machines after a certain point during
installation or afterward.
• using Device Mapper Multipathing with the qla2xxx driver resulted in frequent path failures.
837
(BZ#495635 )
• if the hypervisor was booted with the dom0_max_vcpus parameter set to less than the actual
number of CPUs in the system, and the cpuspeed service was started, the hypervisor could crash.
838
(BZ#495931 )
• using Openswan to provide an IPsec virtual private network eventually resulted in a CPU soft lockup
and a system crash.
• it was possible for posix_locks_deadlock() to enter an infinite loop (under the BKL), causing a
system hang. (BZ#496842
Users should upgrade to these updated packages, which contain backported patches to correct these
issues. The system must be rebooted for this update to take effect.
