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

• 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 function of a privileged
program and possibly execute commands at the elevated privileges if the program file has
the setuid privilege. This patch allows a system administrator to enable memory management
protections that limit potential buffer overflow vulnerabilities.
• Fixes the IDE/ATAPI driver.
• Prevents an IDE bus hang caused when issuing a play audio track command from scu to an
ATAPI CD-ROM containing an enhanced CD.
• Fixes a process hang in ubc_common_lookup.
• Corrects the NFS server's handling of files open for direct I/O.
• 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.
