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

• Corrects a memory leak problem associated with the clu_get_info API seen on stand-alone
systems.
• Corrects potential security vulnerabilities in the gzip program. These vulnerabilities could
be exploited by a remote unauthorized user to execute arbitrary code or cause a Denial of
Service (DoS).
• Fixes a POSIX standard violation in the wcstod() function. Previously, an incorrect pointer
was set to the endptr parameter of wcstod() for cases where no conversion was made.
• Fixes the awk command to ensure that the -f option exhibits the right behavior with numeric
strings.
• Modifies the ex command to return 1 as the exit status when a read-only option with write
fails.
• Changes the return value of swprintf() so it returns the correct value if swprintf() detects an
invalid wide-character.
• Fixes the awk command to ensure that operands that begin with a numeric character or “=”
are considered as valid pathnames.
• Updates the time zone data files in /etc/zoneinfo/ to include the most recent changes from
the latest PD time zone source kit (tzdata2005n).
• Fixes a problem whereby the /proc file system could remain open after a debugging
application exits.
• Corrects a potential security vulnerability issue that could result in unauthorized privileged
access or denial of service (DoS)
• Implements the FC-HBA standard
• Modifies the cksum command to report the correct file size in the xpg4 environment when
the file is greater than 4GB.
• Fixes the problem of syslogd dying intermittently when sent a SIGHUP to reconfigure.
• Fixes the problem of a core dump occurring while running the fsck command on a fake UFS
file system.
• Improves space utilization in small MFS file systems by decreasing metadata overhead.
• Fixes a problem with the mkcdsl command in which the -a option misbehaves when used
on a context-dependent symbolic link (CDSL).
• Fixes RPC timeout error messages in the ypwhich -m command.

• Provides support for identifying references to half-open pipes via the fuser utility.
• Improves performance for some multithreaded applications running on AlphaServer GS320
and GS1280 class systems.
• Corrects a scenario in which a spurious wakeup is sent to a process that had interrupted a
blocked attempt to set a mandatory file lock.
• Provides performance enhancements to the vm_overflow feature.
• Changes the way page migrations occur on a NUMA system to address poor performance
due to excessive paging.
• Corrects an incompatibility between the cpus_in_rad and gh_chunks/rad_gh_regions tunable
attributes that could result in a boot failure.
• Corrects a problem with pagetable page allocations that could leave a thread waiting
indefinitely during a fork operation.
• Corrects "ubc_wire: hash failed" panics on non-NUMA systems.
• Corrects a "not wired" panic that occurs with System V shared memory and bigpages.
• Reduces scheduling contention when unmapping shared address space that has an extremely
high number of mappers.
