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

the setuid privilege. This patch allows a system administrator to enable memory management
protections that limit potential buffer overflow vulnerabilities.
• Installs version V2.1-120 of /usr/lib/libots3.a and /usr/shlib/libots3.so to fix a problem where
long running OpenMP applications might overflow an internal libots3 counter, resulting in
a breakdown of thread synchronization.
• Installs DECthreads V3.20-033, which addresses the possibility of floating point errors in
threaded programs.
• Corrects the behavior of munlockall in the realtime library (librt).
• Improves null partition checking code.
• Fixes a librt memory leak that can occur when multiple message queue files are opened and
then closed. (The memory would be recovered when the process terminates.)
• Expands libpset APIs to enable the caller to get processor set information.
• Installs DECthreads V3.20-029, which fixes problems that may affect threaded programs.
DECthreads V3.20-029 is the initial support version of the HP POSIX Threads Library.
• Installs DECthreads V3.20-049.
• Adds support for NEW_OPEN_MAX_SYSTEM (64K) file descriptors to libaio.
• Installs DECthreads V3.20-049a, which fixes a problem that could cause some threaded
applications to hang.
• Resolves several DECthreads faults and resolves performance issues with certain Java
applications.
Patch 27051.00
OSFLSMBASE540
• Fixes a problem with vold logging (vold -k -x log) in which the default log file cannot be
created.
• Improves LSM's volunmigrate disk processing to produce more informative error messages
on command line errors rather than defaulting to a general usage statement.
• Corrects volunmigrate to allow for the full pathname to the device as input and to properly
reject partitions with an invalid partition length.
• Fixes an issue whereby the volevac command can appear hung when the number of volumes
exceeds 512.
• Provides enhancements to LSM hot-sparing.
• Fixes a problem of adding LUNs off a SWXCR controller to LSM.
• Fixes an issue seen in CLSM that causes a diskgroup import to fail when clsm collision
proposals are seen in messages file.
• Fixes a LSM diskgroup deport problem.
• Prevents a "Too Many Volumes" error when attempting to add a volume and the maximum
volumes allowed has not been reached.
• Fixes an issue with the initialization of large disks.
• Fixes an issue seen when using KZPAC/SWXCR disks in LSM.
• Corrects several label strings in the SysMan LSM application.
• Fixes problems with SysMan LSM administrator that deal with disk names in "Add disk to
LSM" window and the display of disk names in Migrate.
• Allows the LSM voldisk online and voldisk -a online commands to work cluster-wide for
devices that have not been replaced. This is useful for rescanning devices that had a temporary
disk failure.
• Corrects several potential security vulnerabilities where, under certain circumstances, system
integrity may be compromised. These may be in the form of improper file access.
