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

• Corrects a security issue in which rsh and other rcmds incorrectly report ESUCCESS when
the remote side of a connection terminates before fully establishing a connection.
• Updates sysconfig to use the cluster interconnect, thereby allowing for a greater SSI
collaboration. This fix will help with changing variables on hung systems, single user systems,
and normal running systems.
• Improves cryptic warning message during a mount of a dirty file system. The new message
includes a suggestion to run the fsck command for a dirty UFS.
• Adds support in cleanPR for HSG60/HSV100/MSA/HP-XP enclosures.
• Corrects a panic while creating or extending a large UFS file system.
• Fixes cron job scheduling for Daylight Savings time events.
• Corrects a potential security vulnerability where, under certain circumstances, system
integrity may be compromised. This may be in the form of improper file or privilege
management.
• Enables the -undo_switch option for the versw command, which is required to delete patches
that contain version switches.
• Corrects a problem in which cp and cat produce different file sizes when reading from a
tape device.
• Adds SCSI reserve and release support to the mt program to assist open SAN tape
management.
• Updates the environmental monitoring daemon, envmond, to ensure the correct EVM events
are being sent at the correct time.
• Allows the auditing of login and su events based in part on the contents of user profiles (for
Enhanced Security), the prevailing auditing characteristics of the originating process, and
the system-wide audit mask. Previously, only the system audit mask was referenced.
• Fixes many small problems with the dsfmgr command.
• Corrects several potential security vulnerabilities where, under certain circumstances, system
integrity may be compromised. These may be in the form of improper file access.
• Adds an event to indicate that the soft or hard error count has changed on the device
identified in the event.
• Fixes the search algorithm to differentiate between prived and non-prived UIDs, and to
allow regular expressions in string searches.
• Corrects a problem found wherein the rmtmpfiles script would leave empty directories in
/var/tmp at system startup.
• Fixes a problem that occurs while encoding $@ in the Bourne shell.
• Eliminates the warning message "Using an array as a reference is deprecated" when running
/usr/sbin/siacfg and during system boot on systems using Perl 5.8.0 and higher.
• Corrects a potential floating point error in threaded applications.
• Allows the fuser command to display the reference flag, which indicates the type of reference
made; for example, open, closed, unlinked, or mmapped.
• Fixes a problem with csh that occurs when using a tilde (~) operation in directing standard
input and standard output of a command to a file in a home directory.
• Updates ddr.mod to support new hardware (NHD-6) devices.
• Corrects a problem in which crontab removes its entries and the vi editor truncates an
existing file when a file system is full.
• Corrects the way RPC-based servers handle ill-formed TCP connections.
• Allows mount options that take a value to be correctly processed on a cluster.
• Corrects the tar program to properly handle unusual directory specifications.
• Prevents segmentation faults when a malformed argument vector is passed to sia_ses_init.
