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

• Prevents problems in the USB subsystem that include memory leaks, data inconsistencies,
and USB device configuration problems.
• Fixes problems in the USB driver layer that include potentially minor performance
degradations if using USB devices and occasional USB device failures.
• Corrects a problem in which a temporary file is left behind during the creation of bootable
tape with the UFS file system.
• 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 various problems in the bcm driver for DEGXA Gigabit Ethernet adapters.
• Defines new error log entry types for system error logging on certain 21364-based systems.
• Increases the ability to audit memory wire and unwire operations.
• Corrects a problem in which a read or write operation to a changer device creates an
unkillable process.
• Fixes a problem in which clua.mod does not handle TCP RST messages appropriately.
• Increases BOOTP error timeout values for RIS kernel installations.
• Accelerates the boot time on large memory GS systems.
• Provides support for dynamically loadable packet filters.
• Distributes the latest .h files for the mcutil program and the event manager.
• Adds function prototypes for the NUMA APIs cpu_get_current() and cpu_get_rad() to
sys/cpuset.h.
• 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.
