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

• Makes the following changes to the vdump, rvdump, and vrestore commands:
— Causes vdump and rvdump to report when all hard links siblings cannot be archived
through the specified path and causes them to correct the bytes to backup estimate
calculation when hard links are archived.
— Causes vdump and vrestore to act as expected upon receiving an interrupt (^C).
— Fixes vdump and vrestore to pick up correct messages in all locales.
— Causes vdump to avoid some unnecessary function calls, thereby allowing faster
vdumps.
— Fixes vrestore to display bit file attributes with the -l option.
— Prevents vrestore from failing during a remote system call.
— Causes vrestore to display a file and directory name along with the error message when
the command fails to set a property list.
— Prevents vrestore from dumping core when a tape has a smaller blocksize than expected.
— Allows vrestore to handle no-rewind tapes properly.
— Lets vrestore read environment variables for a user-defined device name.
— Allows attributes to set to the top level-directory.
— Disallow block sizes greater than 64 K. (This was a new feature added in Patch Kit 2
which caused forward compatibility problems.)
— Causes files of less than 512 bytes to be properly backed up.
— Corrects a cluster drd bandwidth problem that occurs when a restore is attempted via
a private tape drive that is not on the current node.
— Corrects a condition that could cause the misinterpretation of the archive version in
certain locales, causing vrestore to abort.
• Corrects several problems with the fixfdmn utility:
— Shortens the time it can take to repair large AdvFS file domains.
— Improves the capability of fixfdmn to fix invalid extent data.
— Improves the secure handling of temporary files by fixfdmn.
— 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.
— Improves the ability of fixfdmn to fix on-disk structure version 3 domains.
— Fixes several rare cases where fixfdmn could either fail to correct a domain or incorrectly
make changes to a valid domain.
• 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.
