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

• Fixes many small problems with the dsfmgr command.
• 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 a problem with the AdvFSstat command printing negative values for
statistics that are over 10 decimal digits long.
• Corrects several rare cases in which fixfdmn either did not fix, or incorrectly fixed
data inconsistencies on AdvFS file domains. On large AdvFS file domains, this
patch shortens the time it takes to repair them.
• Causes vdump and rvdump to report when all hard link siblings cannot be archived
through the specified path.
• Causes vdump and rvdump to correct the bytes-to-backup-estimate calculation
when hard links are archived.
• Enhances /sbin/AdvFS/tag2name to print out the name of the associated directory,
given the tag of an index file.
• Allows fixfdmn to repair a rare on-disk structure problem with directories. This
condition only shows up on a domains with multiple volume in which property
lists are used.
• Corrects several very rare cases where fixfdmn incorrectly fixes certain AdvFS file
domains.
• Causes the vdump -C option to display compression ratio.
• Causes vrestore to display error message for end of tape.
• Identifies non-tape target device during rvdump and rvrestore actions.
• Improves the ability of fixfdmn to fix on-disk structure version 3 domains.
• Corrects the value nvbmtpg prints for fs_stat.st_unused_1.
• Ensures that a stripe does not succeed if a write precedes it.
• Corrects the RBMT free mcell count for multipage RBMTs as displayed by nvbmtpg.
• Allows the maximum directory entry name size in the vods tools.
• Corrects several rare cases where fixfdmn incorrectly fixes certain AdvFS file
domains.
• Modifies defragcron.sh to avoid accidentally deleting the /dev/null.
• Enables the vfast utility to run on a standalone system.
• Fixes the vfast utility error "vfast: cannot get frag list; 14 - Bad address"

sub-directories.
