HP Tru64 UNIX and TruCluster Server Version 5.1B-6 Patch Summary and Release Notes

• Adds the ability to join more than 20 IP multicast groups on a given socket.
• Changes the implementation of the NFS server's duplicate request cache from a statically
allocated monolithic entity to a dynamically allocated entity.
• Fixes a problem in which some IP fragments of NFS over UDP read replies may be sent to
the wrong MAC address.
• Improves the performance of systems that perform heavy file I/O.
• Provides an RFC3542 compliant implementation of IPv6 Advanced API.
• Provides support for latest version of bcm card.
• Updates Mobile IPv6 code to be compliant with the latest RFC.
• Fixes MIP6_CACHE_READ_TO_WRITE_LOCK() to not call lock_read_to_write() when in
lockmode=0 to avoid a panic.
• Corrects a problem with HSZ events that cause I/O errors rather than doing the appropriate
retries so the I/O can be successful.
• Adds read/write ability to XP control ports.
• Corrects a problem with a sensor error that can indicate a false over-temperature condition
on DS10/DS10L and TS10 systems.
• Fixes USB problems that prevent some USB keyboards and mice from working.
• Provides enhancements for NetRAIN operation.
• Adds the ability to decouple RPC client retransmission activity from the UDP or interface
transmission completion handling.
• Fixes a logic error in the virtual memory macros used for accessing the memory descriptor.
• Allows multiple retries to mount the root file system and the ability to adjust the retry period.
• Fixes a problem in which the operating system receives an environmental machine check
packet from the firmware but fails to correctly recognize the sensor that is identified as faulty
by the machine check.
• Fixes a problem that prevents keyboard input during interactive booting (SRM boot flag "i")
when in graphics mode on GS1280/ES80/ES47 AlphaServers.
• Enhances the fuser command to provide a cluster-wide query capability. A revised fuser(8)
reference page describes this enhancement.
• Fixes mass storage disk subsystem handling of specific important events reported by the
HSG80 and HSG60 array controllers.
• Provides improvements to the TCP Selective Acknowledgment (SACK) option.
• Provides a workaround for the firmware limitation on SAS kernel size.
• Raises the highest ID handled by edquota and repquota and converts the repquota program
to using the GETQUOTA/GETQUOTA64 quotactl's for obtaining data, instead of directly
reading from the quota file. This results in more recent data and, in a cluster, consistent data
across all nodes. It also enables handling the highest UIDs (up to 4294967294).
• Fixes a problem that corrects the status message which is output during boot operations
before the binary.errlog log file is available.
• Fixes a memory troller panic during a boot in low-memory conditions.
• Fixes a rare kernel memory fault that can occur when booting an AlphaServer ES80.
• Changes I/O retry processing when a command time out is encountered by causing the retry
code to attempt to take advantage of other active paths during retries if command time outs
are encountered.
