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

• Fixes a rare kernel memory fault problem that occurs during an ES80 boot.
• Provides a new cluster-specific link aggregation distribution algorithm when using LAG in
a LAN cluster.
• Allows for control ports to be deleted using the hwmgr command.
• Fixes a potential deadlock hang between a migration and a flush on a file.
• Addresses a potential I/O performance bottleneck in which the tape driver may select the
same path for all tape drives in a system containing multiple HBAs and multiple tapes. The
tape driver can now assign different paths to different tape drives to improve tape I/O
performance.
• Fixes problems that happen when volume expansion (mount -u -o extend) races with other
code.
• Corrects a C++ compilation error when including conf.h.
• Makes the poll() function compliant with revised UNIX98 standards.
• Revises the btcreate utility to overcome the 32MB firmware limitation on SAS kernel size.
• Reduces the default value of IPFRAGTTL from 60 to 18 to avoid reassembly problems.

in the /etc/inetd.conf file to be ignored.
• Fixes a problem with inetd -L in which a cluster loops in shutdown -c or rcinet start.
• Upgrades BIND 8 to BIND 9.
• Fixes a problem that occurs when starting inetd on all RADs in which there are holes between
the RADs.
• Fixes a potential remotely exploitable Denial of Service (DoS) vulnerability in the File Transfer

cause an ftp server to become unresponsive.
