HP CIFS Server 3.0f Release Notes version A.02.03 for HP-UX 11i v3 (December 2006)

Announcement
This document contains information about some enhancements and defect fixes provided in HP CIFS Server
A.02.03, as well as other helpful information. HP CIFS Server A.02.03 is supported on HP-UX release 11i
v1, 11i v2 and 11i v3. The following list is a summary of the changes included in this release.
Summary of changes in HP-UX CIFS Server A.02.03
• This version of HP CIFS Server software is based on Samba 3.0.22 with 3.0.23 selected fixes. HP CIFS
Server A.02.03 on HP-UX release 11i v3 provides new enhancements in addition to enhancements
and defect fixes included in HP CIFS Server A.02.03 on HP-UX release 11i v1 and v2.
• HP CIFS Server A.02.03 for HP-UX 11i v3 includes new functionality to improve interoperability between
CIFS clients and NFS clients. A new dynamically loaded kernel module (DLKM) known as CIFS File
System Module (CFSM) can be used to enforce the file locks held by CIFS clients. Enabling this
functionality prevents the possibility of file corruption due to concurrent file accesses from both CIFS
clients and NFS clients, and allows for performance enhancing opportunistic locks to be safely used.
• This release supports diagnostic functionality to trace the CFSM activities by sending trace messages
to a log file. A new utility, cfsmutil, is used to configure the trace level, log file name and maximum
log file size.
NOTE: The CIFS File System Module (CFSM) and the CFSM tracing features are only available with
the HP CIFS Server on HP-UX 11i v3 and later.
• HP CIFS Server A.02.03 winbind code has been re-designed to support the non-blocking, asynchronous
request/reply behavior with the exception of user and group enumeration. With this new enhancement,
winbind provides better scalability in large domain environments and on high latency networks.
As part of the re-design, winbindd now spawns a winbindd process for the workgroup and each
trusted domain. This means administrators should expect to see an increased number of winbindd
processes running when running in complicated ADS environments.
• This release supports performance enhancements which include enabling the configuration parameter
"use mmap" to take advantage of fixed size memory map access of CIFS's Trivial Database (TDB)
files. The mechanism and number of TDB files using memory-mapped access has been tuned respective
of the OS (HP-UX 11i v3 PA or 11i v3 IA).
For detailed information, refer to the "TDB Memory Map for HP CIFS Server" section of Chapter 13 in
the HP CIFS Server A.02.03 Administrator's Guide or man smb.conf.
• This release supports HP-UX unified file cache functionality on both HP-UX 11i v3 PA and IA systems.
• This release supports HP-UX user and group name of up to 256 bytes.
• This version of the HP CIFS Server addresses problems resolved since version A.02.02.01. Please refer
to the section “Fixes in HP CIFS Server A.02.03 ” (page 8) for details.
WARNING! HP only supports HP CIFS Server binaries as delivered by HP. You must use the swinstall
