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

• Fixes a problem seen with the TAHI IPv6 conformance test, specifically Test 4 for
the IPv6 specification.
• Resolves a problem that results in multiple cluster members crashing with kernel
memory fault in rfs_find_fsid().
• Corrects a potential system hang when an error occurs while updating special file
or named pipe access times on an NFS client.
• Fixes an AdvFS asynchronous direct I/O problem that can cause a thread to hang.
• Fixes a problem in which a truncated AdvFS file erroneously zeros data for the
remaining leading segment of the file.
• Fixes a minor problem in the IPv6 subsystem that causes an extra message to be
sent upon startup.
• Corrects a problem that occurs in some low free memory situations, in which a
kernel thread that completes AIO requests may stall on one request, causing other
requests (that can complete) to back up behind it.
• Improves performance for CFS filesets mounted with the server_only option.
• Allows tasks with just one SCS thread to be migrated in the same manner as single
threaded processes in NUMA environments.
• Addresses a problem in IPv6 subsystem that causes a system to panic.
• Adds support for AlphaServer ES47/ES80/GS1280 platforms to allow the use of
processors having different speeds in the same chassis.
• Corrects the problem of the statfs() function returning EINVAL when operating
on an fattach() function clone streams device.
• Addresses a scaling issue seen on large multiprocessor systems in dealing with
the class scheduling subsystem.
• Fixes a problem in gh_chunks allocation on some configurations.
• Improves file caching performance for large files on NUMA systems.
• Fixes panic: simple_lock_terminate: lock busy.
• Fixes cluster crashing when VMAC is enabled
• Fixes an underlying problem in the NFS client that can lead to a panic on a single
system or an assertion failure panic on a cluster.
• Fixes the number of cylinders defined in the last cylinder group of a UFS file system
that has been extended.
• Fixes various problems in the bcm driver for DEGXA Gigabit Ethernet adapters.
• Removes the 32-bit block address restriction in SpecFS read and write.
• Removes excess data stored in the auditing of the swapctl syscall.
• Adjusts the automatic computation of the size of the NFS server's duplicate request
cache to accommodate only active RADs on a multi-RAD system.
• Increases ability to audit memory wire and unwire operations.
• Resolves a problem affecting IPv6 sockets where a packet transmission might fail
when the destination address is not specified.
