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

tape driver can now assign different paths to different tape drives to improve tape I/O
performance.
• Fixes problems that happen when volume expansion (mount -u -o extend) races with other
code.
• Corrects a C++ compilation error when including conf.h.
• Makes the poll() function compliant with revised UNIX98 standards.
• 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 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.
