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

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.
• 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.
