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

• Adds the function prototype numa_query_pid() to numa.h.
• Changes the use of /etc/svc.conf to /etc/nsswitch.conf to allow netgroup data to be provided
from LDAP in addition to NIS.
• Provides support for the Philips USB controller, which is shipped on some AlphaServer
GS1280 systems. Without this patch, the Philips USB controller may fail to detect and
configure devices connected to it.
• 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.
• Corrects a problem in which /sbin/ddr_config does not accept values for ReadyTimeSeconds
larger than 255. The new limit is 86400 seconds (24 hours).
• Fixes problems with NUMA disk statistics.
• Fixes a KMF problem that can occur when some nodes in cluster are rebooted and a device
is shared by all the nodes.
• Changes the CAM subsystem message that is printed to the error log on a recovered read
error from "bad block number" to "block number."
• Adds per-binary big page controls to complement the system-wide tunable attributes.
• Fixes how the NFS client handles full NFS version 3 64-bit fields.
• Corrects a potential security vulnerability where, under certain circumstances, system
integrity may be compromised. This may be in the form of improper file or privilege
management.
• Corrects a problem with hwmgr utility deletes while a SCSI scan is in progress.
• Improves scaling of IP reassembly code on large SMP machines. NFS servers are especially
susceptible when a large number of clients attempt to write at the same time.
• Implements buffer cache page checksum caching for NFS client pages.
• Corrects a kernel memory fault caused by configuring a system to be a firewall router without
having the GWSCREEN subsystem built into the running kernel.
• Improves performance for applications with large in-core data sets.
• Corrects a problem in which the less than (<) and greater than () keys on the Norwegian
keyboard do not work in single-user mode.
• 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.
