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

• Corrects problems with name resolution when an error is encountered during the
processing of the local host files.
• Fixes a yacc stack overflow error in the Tru64 UNIX assembler.
• Fixes a fatal error in /usr/bin/spike.
• Fixes problems such as segmentation faults caused by the strxfrm() function running
on the French locales.
• 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 a performance problem in the libc mktime() routine.
• Corrects a problem in which the rewind() function would fail to reposition to the
beginning of a file.
• Corrects a failure in the safe_open() routine that caused symbolic links given by
a relative path from the current working directory sometimes to give ENOENT
errors incorrectly.
• Corrects an odd, unexpected error message that may be printed by rsh or rlogin
commands.
• Corrects a problem where the telnet command causes unnecessary delays when
an IP address is supplied as a command-line argument.
• Corrects a problem in which a DNS resolver routines never time out if interrupted
by signals.
• Provides an RFC3542 compliant implementation of IPv6 Advanced API.
• Fixes a nonconcurrency issue for multithreaded applications calling popen() and
certain "FILE *" routines such as fread().
• Fixes a deadlock condition in multithreaded applications that call fork() and other
libc callback routines such as exit handlers, __fini_* routines.
• Corrects a condition in which multiple "Sorry" messages are issued by the su
command when multiple SIA mechanisms are in use (as when LDAP is configured
for user accounts).
• Improves the performance of times(3).
• Enhances the fuser command to provide a cluster-wide query capability. A revised
fuser(8) reference page describes this enhancement.
• Fixes a problem with glob() returning an incorrect match when directory
permissions issues exist.
