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

Fixes a logic error in the virtual memory macros used for accessing the memory descriptor.
Allows multiple retries to mount the root file system and the ability to adjust the retry period.
Fixes a problem in which the operating system receives an environmental machine check
packet from the firmware but fails to correctly recognize the sensor that is identified as faulty
by the machine check.
Fixes a problem that prevents keyboard input during interactive booting (SRM boot flag "i")
when in graphics mode on GS1280/ES80/ES47 AlphaServers.
Enhances the fuser command to provide a cluster-wide query capability. A revised fuser(8)
reference page describes this enhancement.
Fixes mass storage disk subsystem handling of specific important events reported by the
HSG80 and HSG60 array controllers.
Provides improvements to the TCP Selective Acknowledgment (SACK) option.
Provides a workaround for the firmware limitation on SAS kernel size.
Raises the highest ID handled by edquota and repquota and converts the repquota program
to using the GETQUOTA/GETQUOTA64 quotactl's for obtaining data, instead of directly
reading from the quota file. This results in more recent data and, in a cluster, consistent data
across all nodes. It also enables handling the highest UIDs (up to 4294967294).
Fixes a problem that corrects the status message which is output during boot operations
before the binary.errlog log file is available.
Fixes a memory troller panic during a boot in low-memory conditions.
Fixes a rare kernel memory fault that can occur when booting an AlphaServer ES80.
Changes I/O retry processing when a command time out is encountered by causing the retry
code to attempt to take advantage of other active paths during retries if command time outs
are encountered.
Patch 27012.00
OSFC2SEC540
Modifies the prpasswdd and rpc.yppasswdd daemons to properly handle /var/tcb/files on
a file system from different from /var.
Fixes client login, su, rshd, edauth, and sshd2 hangs and long delays under Enhanced
Security, as well as some intermittent errors or failures seen with prpasswdd or
rpc.yppasswdd.
Corrects a problem in which logins in TruCluster environments using Enhanced Security
can hang on any member other than the one serving /var to CFS.
Fixes a problem in which group and other read privileges get stripped from /etc/passwd
when a user switches from enhanced to base security.
Corrects a problem on systems running Enhanced Security in which the command edauth
-R refuses to write user-profile entries to the root partition.
Corrects a problem that occurs when using C1crypt for password encryption on Enhanced
Security systems in which users are unable to change their passwords and see the passwd
command warning "Password not changed: failed to write protected password entry."
Changes the use of the configuration file /etc/svc.conf to /etc/nsswitch.conf to allow netgroup
data to be provided from LDAP, rather than only from NIS.
Fixes problems with Enhanced Security user accounts that reference a template.
Patch 27013.00
OSFCDEAPPS540
Corrects a potential security vulnerability where, under certain circumstances, system
integrity may be compromised. This may be in the form of improper file access.
Corrects a problem in which dtcm dumps core when the following steps are taken:
