HP Tru64 UNIX and TruCluster Server Version 5.1.B-4 Patch Summary and Release Notes (13156)

• Removes erroneous "No B-cache detected" messages from certain configurations.
• Prevents a potential panic that generates the message “memory_test=partial” or
“memory_test=none.”
• Allows the stat system call to correctly report the st_blocks on a CD-ROM file.
• Improves performance for applications with large in-core data sets
• Corrects a system panic caused by stack growth.
• Adds the ability to join more than 20 IP multicast groups on a given socket.
• Fixes a multiple process hang (which cannot be terminated with Ctrl/c) that can occur if
process A attempts to attach process B to another RAD while at the same time, process B
attempts to attach process A to another RAD (a classic deadlock).
• Changes the implementation of the NFS server's duplicate request cache from a statically
allocated monolithic entity to a dynamically allocated entity.
• Corrects a kernel memory fault panic under certain heavy system loads when using the
/proc file system to debug processes.
• Corrects a problem in which using PRSABORT in the /proc file system does not correctly
abort a system call in the process being debugged.
• Fixes a "simple_lock: time limit exceeded" panic involving the vm_object.ob_lock lock.
• Fixes a rare case of a thread blocking when waiting for memory.
• Fixes a problem in which some IP fragments of NFS over UDP read replies may be sent to
the wrong MAC address.
• Permits the setting of the setuid, setgid and sticky bits on NFS served files.
• Fixes kernel memory faults that can occur when packetfilter support is used incorrectly as
a result of the following:
— A misconfiguration of the packetfilters system configuration parameter in the net
subsystem.
— The dynamic load of the packetfilter subsystem on a system that has packetfilter statically
built into the kernel.
• Fixes a condition in which the fork() function returns EAGAIN incorrectly on a process using
gh_chunks.
• Corrects a problem in which interface Unicast packet counters seem to go backwards when
retrieved via SNMP.
• Improve the performance of systems that are performing heavy file I/O.
• Corrects several minor problems with the IPv6 subsystem related to the Neighbor Discovery
specification.
• Provides an RFC3542 compliant implementation of IPv6 Advanced API.
• Fixes a panic condition caused by a problem in the swapping subsystem.
• Allows the niffconfig command to exceed 10 interfaces.
• Corrects a potential kernel memory fault.
• Fixes a problem of a system hang that occurs when the system may be swapping
• Fixes overall system instability caused by the pshare subsystem
• Speeds up the discovery of a healthy cluster interconnect interface by helping NetRAIN
failover to a redundant healthy interface before the (Internode Communication Services)
begins to time out on the keepalives, thereby preventing the cluster from crashing.
• Fixes certain panics conditions by increasing the timeout for CPU onlines.
• Updates Mobile IPv6 code to be compliant with the latest RFC.
• Corrects the handling of a condition that can lead to a panic under heavy system load with
high swap activity.
• Corrects a problem in which the cp -p command will not copy DMAPI-managed region
information.
• Addresses an issue in which the default value for kernel flag mobileipv6_enabled is 1
