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

• Fixes a condition that causes a connection timeout error when using socket
keepalive options with small values on sockets over a localhost connection.
• Corrects the cause of the a panic: "panic: Hashing that is not marked VPP_REPL."
• Corrects a problem in the kernel dli module that causes system hangs and crashes
on multi-CPU systems. The crashes occur with the panic string "lock_terminate:
lock held".
• Fixes a logic error in the virtual memory macros used for accessing the memory
descriptor, based on physical address.
• Corrects the panic “trap: invalid memory read access from kernel mode” in pshared
code.
• Corrects a problem with the randomization of initial TCP sequence numbers.
• Allows multiple retries to mount the root file system and the ability to adjust the
retry period.
• Enhances the range of generic sysconfig parameters and eliminates unnecessary
sysconfig warning messages.
• Corrects several problems related to use of the ifconfig [interface] IPv6 up
command, where interface is either cluster interconnect, ics0, or configured v6-in-v6
tunnel.
• Fixes an NFS client kernel loop that usually results in a lock time limit exceeded
panic on partitioned GS1280 class systems in partitions where CPUs have different
numbers of neighbors. That usually requires a partition of more than four CPUs.
• Ensures that the socket send buffer size will be twice the maximum segment size
if the mss is 1460 bytes.
• Fixes a problem that causes a hang or crash when auditing the network events
“net_tcp_stray_packet,” “ net_udp_stray_packet,” and “net_tcp_rejected_conn.”
• Corrects a problem with the audit object deselection mode in which it was possible
for events that modify a target object to be deselected, resulting in no audit record
being generated.
• Corrects for a leak of CONTROL mbufs.
• Fixes a problem in which a threaded program tries to wake up a thread that is
already running.
• Enhances the fuser command to provide a cluster-wide query capability. A revised
fuser(8) reference page describes this enhancement.
• Fixes a problem in which the traceroute command will timeout when probing the
cluster alias address from a cluster member.
• Corrects a memory leak against the 128-byte bucket when rad_gh_regions are
configured and nshmget() is used.
• Adds support for ifconfig [inet6] delete [abort], for IPv6 connections.
• Corrects a problem in which the netstat -s command does not display the correct
global statistics on multi-CPU systems if lower-numbered CPU slots are empty.
• Corrects a memory leak in IPv6 transmission code.
