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

• Fixes a POSIX standard violation in the strfmon() function by causing preceding and following
spaces to be padded to the return value to make an equal length between positive and
negative values.
• Fixes the getnameinfo routine to display an IPv4 address instead of an IPv4 mapped IPv6
address when the BIND mapping does not exist.
• Fixes issues with "disklabel -e" that occur when extending a disk partition currently in use
and open.
• Allows the fsdb utility to work on a file system image contained in a regular file, as well as
a device. Previously, fsdb could analyze only special files, not regular files.
• Corrects a memory leak problem associated with the clu_get_info API seen on stand-alone
systems.
• Corrects potential security vulnerabilities in the gzip program. These vulnerabilities could
be exploited by a remote unauthorized user to execute arbitrary code or cause a Denial of
Service (DoS).
• Fixes a POSIX standard violation in the wcstod() function. Previously, an incorrect pointer
was set to the endptr parameter of wcstod() for cases where no conversion was made.
• Fixes the awk command to ensure that the -f option exhibits the right behavior with numeric
strings.
• Modifies the ex command to return 1 as the exit status when a read-only option with write
fails.
• Changes the return value of swprintf() so it returns the correct value if swprintf() detects an
invalid wide-character.
• Fixes the awk command to ensure that operands that begin with a numeric character or “=”
are considered as valid pathnames.
• Updates the time zone data files in /etc/zoneinfo/ to include the most recent changes from
the latest PD time zone source kit (tzdata2005n).
• Fixes a problem whereby the /proc file system could remain open after a debugging
application exits.
• Corrects a potential security vulnerability issue that could result in unauthorized privileged
access or denial of service (DoS)
• Implements the FC-HBA standard
• Modifies the cksum command to report the correct file size in the xpg4 environment when
the file is greater than 4GB.
• Fixes the problem of syslogd dying intermittently when sent a SIGHUP to reconfigure.
• Fixes the problem of a core dump occurring while running the fsck command on a fake UFS
file system.
• Improves space utilization in small MFS file systems by decreasing metadata overhead.
• Fixes a problem with the mkcdsl command in which the -a option misbehaves when used
on a context-dependent symbolic link (CDSL).
• Fixes RPC timeout error messages in the ypwhich -m command.
• Corrects a problem in which SysMan and SysMan Station are not functional after installing
Java 1.3.1-4 or higher.
• Prevents addvol from adding invalid disks into a domain.
• Reduces cluster files system I/O in Enhanced Security.
• 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.
