HP Tru64 UNIX and TruCluster Server Version 5.1B-5 Patch Summary and Release Notes (March 2009)

• Fixes a kernel memory fault panic while running the IDRIS benchmark.
• Corrects a kernel memory fault caused by configuring an IPv6 address on a legacy
network interface card.
• Fixes multiple problems with IPv6 advanced API implementation.
• Corrects a problem in which calling aio_write with a negative size may cause a
system panic.
• Corrects a potential security vulnerability reported by SSRT2323.
• Fixes a leak of kernel address space.
• Corrects a problem in which a read or write operation to a changer device creates
an unkillable process.
• Corrects the panic “trap: invalid memory read access from kernel mode in
procfs_psinfo().”
• Corrects a condition in which big page memory allocations on NUMA systems
may allocate remote memory too soon.
• Fixes a problem in which clua.mod does not handle TCP RST messages
appropriately.
• Updates ICMP code to add redirect timeout support and nonmodifiable route
table entries.
• Addresses performance issues with the select() function.
• Accelerates the booting of memory GS systems.
• Adds pfilt_loopback and pfilt_physaddr kernel flags for controlling packetfilter
written packets.
• Corrects a "simple_lock: time limit exceeded" issue that can occur in the CAM I/O
subsystem when MCS locking is disabled.
• Provides support for the dynamically loadable packet filter.
• Fixes IP multicast packets to work with loopback traffic
• Improves NFS client performance on NUMA systems by doing a better job
distributing data, locks, and nfsiod threads across Resource Affinity Domains
(RADs).
• Enables suitable monitoring of individual NetRAIN interfaces
• Provides a tunable attribute that gives system administrators the ability to adjust
the weight that the kernel places on the NUMA locality for forks on AlphaServer
GS80, GS160, GS320, and GS1280 systems.
• Sets a software limit to prevent serious performance problems that can occur when
TCP connections that have an rate-limit enforced by a downstream network device
overrun the device.
• Adds per-binary big page controls to complement the system-wide tunable
attributes.
• Enhances HP-XP array controller support and possible future new tape device
support.
