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

• 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
• 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.
• Corrects a problem in which volmigrate returns a shell error when attempting to migrate
an AdvFS domain with multiple filesets. These domains can now be migrated as long as all
the filesets are mounted.
• Prevents inconsistent LSM volumes when the name of a partition that is being encapsulated
matches the name of a current LSM volume.
• Corrects a problem in which smsd triggers LSM configuration errors when querying LSM
in a cluster. This fix ensures that a cluster member will be up to date with respect to the LSM
configuration when calls are made to an internal LSM routine.
• Corrects a problem during the creation of a new plex in which the volmake command reports
that associating a subdisk with the plex would cause an overlap with another subdisk when
they should not be overlapping.
• Prevents vold from core dumping when attempting to delete a disk that was not initialized
properly.
• 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.
• Corrects an I/O performance issue that occurs when CLSM is configured and one member
of a cluster goes down unexpectedly.
• Fixes a slow boot when booting several cluster nodes at the same time and CLSM is
configured.
• Enables volassist to create a mirror of a striped volume with the mirror having a layout of
concat.
• Corrects an error return code for volinfo. If a specified volume is not in the configuration
database, the error code returned from volinfo will reflect this error.
• Corrects an issue of a cluster node hanging during a boot while another member recovers
the cluster root file systems.
• Allow volsave and volrestore to save nconfig/nlog policies for disk groups and restore them
appropriately.
• Corrects awk errors for invalid quit statements.
• Corrects a problem in which lsmbstartup does not ignore comment lines in /etc/fstab, thereby
making it possible for it to attempt to process that line if it appears to be an entry for the
root file system.
