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

• Corrects tracking of controlling terminal reference to session structure.
• Corrects a problem that causes the transmission of duplicate FIN packets, which
could result in a stuck connection.
• Allows systems with multiple paths to a large number of devices to boot faster.
• Fixes an issue with the NFS client async daemon that can occur in specific NUMA
configurations. These configurations would have RAD numbers that are not part
of the partition but within the range of valid RAD numbers for that partition.
• Fixes an fsync (NFS/UFS) operation that failed to always flush all dirty pages.
• Fixes a “lock_done: lock not currently owned” panic that occurs early in a boot.
• Resolves lock management issues within the UBC that can lead to “mcs_unlock:
current lock not found” and “mcs_lock: time limit exceeded” panics.
• Removes NFS warning message about malaligned RPC messages.
• Makes the poll() function compliant with revised UNIX98 standards.
• Fixes a hang caused by the Async I/O subsystem.
• Corrects a problem with the mount command in which issuing a mount -l command
lists the property of a dual mounted fileset incorrectly as nodual.
• Fixes a problem that causes some TCP connections to reset when sending large
amounts of data (more than 2GB) to a very efficient receiving host.
• Corrects the incompatibility of the waitpid() system call with revised UNIX98
standards.
• Fixes an internal kernel declaration for variable maxuthreads that resolves the
following types of kernel failures when the sysconfig value for
max_threads_per_user in the proc subsystem is set to a value larger than
2147483647:
thread_create() failed for pid # : maxuthreads (=-1) exceeded for uid 201
thread_create() failed for pid 1479950: maxuthreads (=-#) exceeded for uid 15
• Fixes a panic resulting from CDFS using a deallocated vnode.
• Corrects a problem in which the tmt_walk_list() function in nifftmt.c mallocs
memory for the tmt_state_info array, but fails to free memory when thread
terminates.
• Reduces the default value of IPFRAGTTL from 60 to 18 to avoid reassembly
problems.
• Modifies the setluid system call to handle the license correctly when a non-root
user switches to different non-root user using login command.
• Corrects a problem in which elevated load averages were reported on NUMA
class systems.
• Fixes resource leaks seen after a device file is revoked.
