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

• Revises the btcreate utility to overcome the 32MB firmware limitation on SAS
kernel size.
• Reduces the default value of IPFRAGTTL from 60 to 18 to avoid reassembly
problems.
• Provides an option that allows cluster NFS clients to use a nonprivileged TCP port
to see if a remote NFS server is up.
• Allows the hwmgr redirect scsi command to work with lockmode 4.
• Corrects a problem in which the heavy use of the cluster alias on large SMP and
NUMA machines results in excessive context switching and CPU load.
• Enables SmartArray 5300 controller hardware events to be logged to the
binary.errlog during boot time. This is useful in diagnosing logical volume
state change and physical drive hotswaps that can occur while the system in not
booted.
• Corrects a potential security vulnerability where, under certain circumstances,
system integrity may be compromised. This may be in the form of improper file
access.
• Adds SCSI reserve and release support to mt to assist open SAN tape management
• Fixes a problem with audit data not being displayed by the audit tool.
• Corrects problems with file object selection and deselection and directories.
• Corrects NUMA performance issues associated with auditing.
• Adds support for IEEE 802.1Q (VLAN).
• Adds support for IEEE 802.1Q (VLAN) (DE50x, lan_common.h).
• Adds support to get live status information for air movers and power supplies on
AlphaServer GS1280 systems and to log intrusion packets to the error log.
• Adds support for CPU indictment on AlphaServer GS1280 platforms.
• Fixes a panic condition in which the operating system erroneously reboots instead
of halting and fails to take a crash dump.
• Fixes numerous issues in the driver for DEGXA Gigabit Ethernet adapters, including
the DS25 on board 10/100/1000 port.
• Adds defensive programming to stat.h to prevent it from getting confused if one
of its internal temporary #defines is defined before stat.h is processed.
• Corrects a problem in which the btextract utility was not preventing the advanced
mode of restore for a system with LSM setup.
• Removes files created under /usr/lib/sabt during the running of the btcreate utility
on file systems with LSM. Previously, these files were copied to the tape, and
would be restored as if they were archived by btcreate.
• Addresses problems with the mksas utility in which false warning messages are
generated and the user-specified temporary directory can be erroneously removed.
• Provides protection against a class of potential security vulnerabilities called buffer
overflows. Buffer overflows are sometimes exploited in an attempt to subvert the
