How Lsof Works
==============

Using available kernel data access methods -- getproc(), getuser(),
kvm_*(), nlist(), pstat(), read(), readx(), /proc -- lsof reads
process table entries, task table entries, user areas and file
pointers to reach the underlying structures that describe files
opened by processes.

Lsof interprets most file node structures -- advfsnodes, autonodes,
cnodes, cdrnodes, devnodes, fifonodes, gnodes, hsnodes, inodes,
mfsnodes, pcnodes, procnodes, rnodes, snodes, specnodes, s5inodes,
tmpnodes.  It understands NFS connections.  It recognizes FIFOs,
multiplexed files, Unix and Internet sockets.  It knows about
streams.  It understands /proc file systems for some dialects.  On
many dialects it recognizes execution text and library references.
It knows about AFS on some Unix dialects.


Lsof Output
===========

The lsof output describes:

    * the identification number of the process (PID) that has opened
      the file;

    * the process group identification number (PGID) of the process
      (optional);

    * the process identification number of the parent process (PPID)
      (optional);

    * the command the process is executing;

    * the owner of the process;

    * for all files in use by the process, including the executing
      text file and the shared libraries it is using:

      * the file descriptor number of the file, if applicable;

      * the file's access mode;

      * the file's lock status;

      * the file's device numbers;

      * the file's inode number;

      * the file's size or offset;

      * the name of the file system containing the file;

      * any available components of the file's path name;

      * the names of the file's stream components;

      * the file's local and remote network addresses;

      * the TLI network (typically UDP) state of the file;

      * the TCP state, read queue length, and write queue length
	of the file;

      * the file's TCP window read and write lengths (Solaris
	only);

      * other file or dialect-specific values.


Getting Started Quickly
=======================

If you want to get started using lsof quickly, or see some examples
of how lsof can be used, consult the 00QUICKSTART file of the lsof
distribution.

The 00QUICKSTART file won't help you build or install lsof, but it
will cut through the density of the lsof man page, giving you more
readily an idea of what you can do with lsof.

For information on building and installing lsof, consult the 00README
file of the lsof distribution.


Limiting, Filtering, and Selecting Lsof Output
==============================================

Lsof accepts options to limit, filter, and select its output.
These are the possible criteria:

    * Process ID (PID) number -- to list the open files for a given
      process;

    * Process Group ID (PGID) -- to list the open files for all
      the processes of a given process group;

    * User ID number or login name -- to list the open files for
      all the processes of a given user;

    * Internet address -- to list the open files using a given
      Internet address (host name), protocol, or port (number or
      name); or to list all open Internet files;

    * command name;

    * file descriptor name or number;

    * list all open NFS files;

    * list all open Unix domain socket files;

    * list all uses of a specific file;

    * list all open files on a file system.

Selection options are normally ORed -- i.e., an open file meeting
any of the criteria is listed.  The selection options may be ANDed
so that an open file will be listed only if it meets all the
criteria.

In the absence of any selection criteria, lsof lists files open to
all processes.


Parsing Lsof Output with Another Program
========================================

The lsof -F option directs it to produce "field" output that can
easily be parsed by another program.  The lsof distribution contains
sample awk, perl 4, and perl 5 scripts in its scripts subdirectory
that show how to post-process field output.


Repeat Mode
===========

Lsof can be directed to produce output, delay for a specified time,
then repeat the output, cycling until stopped by an interrupt or
quit signal.  This mode is useful for monitoring the status of some
file operation -- e.g., an ftp transfer or a tape backup operation.

Repeat mode is more efficient when combined with lsof's selection
options, since they limit lsof overhead.

It's possible to use lsof's field output options to supply repeat
mode output to another process for its manipulation.  The scripts
subdirectory of the lsof distribution has sample Perl scripts
showing how to consume lsof repeat mode output from a pipe.


Distribution Restrictions
=========================

Lsof may be used and distributed freely, subject to these limitations:

1. Neither the author nor Purdue University is responsible for
   any consequences of the use of this software.

2. The origin of this software must not be misrepresented, either
   by explicit claim or by omission.  Credit to the author and
   Purdue University must appear in documentation and sources.

3. Altered versions must be plainly marked as such, and must not
   be misrepresented as being the original software.

4. This notice may not be removed from or altered in the lsof source
   files.


Cautions
========

Lsof is a tool that is closely tied to the Unix operating system
version.  It uses header files that describe kernel structures and
reads kernel structures that typically change from OS version to
OS version.

DON'T TRY TO USE AN LSOF BINARY, COMPILED FOR ONE UNIX OS VERSION,
ON ANOTHER.

On some Unix dialects, notably SunOS and Solaris, lsof versions
may be even more restricted by architecture type.  An lsof binary,
compiled for SunOS 4.1.3 on a sun4c machine, for example, won't
work on a sun4m machine.

AN LSOF BINARY, COMPILED FOR ONE SOLARIS 1.X ARCHITECTURE, ISN'T
GUARANTEED TO WORK ON A DIFFERENT SOLARIS 1.X ARCHITECTURE.


Distribution Contents
=====================

The lsof distribution is checked for completeness when it is
constructed and by the Inventory script when you run the Configure
script.  (See The Inventory Script section of the 00README file of
this distribution.)

Lsof is organized in these parts:

    *  The main lsof directory, containing common sources,
       configuration and setup scripts and three subdirectories:
       dialects/, lib/, and scripts/.

       Lsof is compiled in the main lsof directory after configuration.
       The selected dialect sources are copied or linked from the
       specified subdirectory.  (Symbolic linking is the standard
       method.)

       Common lsof definitions may be found in lsof.h; common
       function prototypes, proto.h; and common storage, store.c.

    *  The dialects/ subdirectory contains subdirectories with
       sources specific to UNIX dialect implementations -- e.g.,
       the dialects/sun/ subdirectory contains sources for the
       SunOS (Solaris 1.x) and Solaris (2.x) implementations of
       lsof.  The dialects subdirectories also contain Makefiles
       and scripts for assisting dialect source configuration.

       Dialect configuration definitions may be found in dlsof.h;
       other dialect definitions, dlsof.h; dialect prototypes,
       dproto.h; and dialect storage, dstore.c.

    *  The lib/ subdirectory contains sources for common lsof
       functions.  Not all dialects use the functions -- some have
       their own versions of them.  The lib/ functions are enabled
       and customized with #define's in the dialect machine.h header
       files.

    *  The scripts/ subdirectory contains sample scripts for
       processing lsof field (-F) output.  The scripts are written
       in AWK, Perl 4, and Perl 5.

The 00PORTING file of the lsof distribution has more information
on lsof components, configuration, and construction.


Warranty
========

Lsof is provided as-is without any warranty of any kind, either
expressed or implied, including, but not limited to, the implied
warranties of merchantability and fitness for a particular purpose.
The entire risk as to the quality and performance of lsof is with
you.  Should lsof prove defective, you assume the cost of all
necessary servicing, repair, or correction.


Bug Reports
===========

Now that the obligatory disclaimer is out of the way, let me hasten
to add that I accept lsof bug reports and try hard to respond to
them.  I will also consider and discuss requests for new features,
ports to new dialects, or ports to new OS versions.

PLEASE DON'T SEND A BUG REPORT ABOUT LSOF TO THE UNIX DIALECT
VENDOR.

At worst such a bug report will confuse the vendor; at best, the
vendor will forward the bug report to me.

Please send all bug reports, requests, etc. to me via email at
<abe@purdue.edu>.


The lsof-l Mailing List
=======================

Information about lsof, including notices about the availability
of new revisions, may be found in mailings of the lsof-l listserv.
For more information about it, including instructions on how to
subscribe, read the 00LSOF-L file of the lsof distribution.


Version 3 Release Notes
=======================

See 00DIST in the last lsof 3 revision 3.88, for its complete
set of release notes.  Lsof revision 3.88 may be found at:

	ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/OLD

3.0		May 24, 1994
		This is the first official release of lsof 3.

...

3.88		February 17, 1997

		+======================================+
		| This is the last version 3 revision. |
		+======================================+

		Added documentation files -- 00.README.FIRST[_<version>]
		and 00RELEASE.SUMMARY_<version> -- to the distribution.


What's new in Version 4
=======================

The main goal of version 4 was to eliminate the confusing common/
fragment source file technique.  Changing the version number also
provided an opportunity to restart the numbering, which at 3.88
had risen to a large value.

The sources that appeared in the dialects/common subdirectory of
version 3 in fragment files have been incorporated into the version
4 liblsof.a library as *.c files.  This results in significant
changes to many source files, scripts, and Makefiles of all dialect
versions.  It allows elimination of some source files -- ddev.c,
dfile.c, dmnt.c -- for dialects now obtaining functions from
liblsof.a that formerly came from making dialect source files by
combining fragment files.

The version 4 liblsof.a sources are stored in the lib/ subdirectory
of the main lsof directory.  The liblsof.a functions are activated
and conditioned in their source files by values #define'd in the
dialect dlsof.h and machine.h header files.

Dialects that provide a private version of a library function refrain
from #define'ing the symbol that would activate the library function
code.


Version 4 Release Notes
=======================

4.0		February 24, 1997

		+====================================+
		| This is the first lsof 4 revision. |
		+====================================+

		Reorganized sources: eliminated code fragment files
		and created a library in their place.  Modified or
		deleted many dialect source and header files.
		Changed documentation accordingly.

		Added a warning to sgi/Makefile and 00FAQ that advises
		against using the IRIX C compiler -n32 option when
		compiling lsof.  Thanks go to Peter Ilieve
		<peter@memex.co.uk> for bringing this to my attention.

		Dropped IRIX 5.2 in mid-stream, because my 5.2 test
		system was upgraded to 5.3.

4.01		March 3, 1997
		Added TFS support for Pyramid dialects.

		Added test to Configure and to the IRIX dnode.c
		for the different cnode struct that appears in
		<cachefs/cachefs_fs.h> on the 6.2 IMPACT distribution.
		Heddy Boubaker <boubaker@amfou.cenatls.cena.dgac.fr>
		alerted me to the cnode change and helped test this
		lsof adjustment.

		Shut down the lsof child process before doing a -r
		sleep().  A comment from Dan Mercer <dam@mmm.com>
		prompted this.

4.02		March 21, 1997

		Based on a report from Pasi Kaara <Pasi.Kaara@atk.tpo.fi>,
		disabled HP-UX CCIT support in lsof for HP-UX
		versions 10 and above.  Pasi's report also led to
		changes in the HP-UX machine.h to support use of
		gcc to compile lsof for HP-UX 10.20 and warnings
		against using `cc -Aa` or `gcc -ansi` to compile
		lsof under HP-UX 10.x.

		With help from Richard Allen <ra@hp.is> taught
		HP-UX 10.x lsof to name file systems better by
		using the virtual file system device number.  Elias
		Halldor Agustsson <elias@rhi.hi.is> provided a test
		system.

		Changed NEXTSTEP and UNIXWARE Makefiles to use
		safer quoting when generating version.h.  The change
		was suggested by Bob Farmer <ucs_brf@unx1.shsu.edu>.

		Added SHELL=/bin/sh string to all Makefiles.

		Added support for Linux 2.1.28 on a test system,
		kindly provided by Jonathan Sergent <sergent@purdue.edu>.
		Configure tests the Linux 2.1.x's C library lseek()
		function for proper handling of kernel offsets.
		If lseek() appears suspect, Configure activates
		the use of a private lseek() function.  Changed
		the private nlist() function to nlist_private()
		and taught it to use the query_module() syscall in
		place of the deprecated get_kernel_syms() one.
		Added rudimentary AX.25 support for Pierfrancesco
		Caci <ik5pvx@infogroup.it> who helped test it.
		Updated the old get_kernel_syms() code to recognize
		and skip module name entries.

		Prompted by Marty Leisner <leisner@sdsp.mc.xerox.com>,
		eased the requirement that service name lookup for
		the -i option be accompanied by a protocol name.  The
		name is not needed if both TCP and UDP names yield the
		same port number.

		Added xusers.awk script from Dan Mercer <damercer@mmm.com>
		to the distribution scripts/ subdirectory.

		Changed Configure script to use LSOF_VERS for all
		UNIX dialect version numbers and to pass LSOF_VERS
		to the dialect Mksrc functions.  Also added the
		ability for a dialect stanza to declare a different
		dialect Makefile source.  Modified dialect Mksrc
		files -- e.g., linux and sun -- accordingly.

		Added support for BSD/OS 3.0 with help from Jim
		Reid <jim@mpn.cp.philips.com>.  Terry Kennedy
		<TERRY@spcvxa.spc.edu> kindly provided a test
		system.  During the port corrected a bug that
		prevented proper handling of revoked files.

4.03		April 7, 1997
		At the suggestion of Dan Mercer <damercer@mmm.com>,
		made HP-UX building of lsof aware of differences
		between the HP-UX bundled and unbundled C compilers.

		Added the ability for the lsof builder to define the
		default warning message issuance state.  By default the
		issuance of warning messages is disabled; defining
		WARNINGSTATE in machine.h disables it.  The Customize
		script was updated to handle WARNINGSTATE.  Dan Mercer
		suggested this.

		Eliminated compiler complaint about improperly cast
		get_Nl_value() argument in ncache_load() in lib/rnch.c.

		Corrected zeromem() argument error in SCO dproc.c.
		Sped up parent directory cache lookup slightly.

		Updated for PTX 4.4, including additional VxFS (EFS)
		file system support.

4.04		April 17, 1997
		At the suggestion of Bela Lubkin <belal@sco.COM>
		changed device cache handling to be more tolerant
		of a device cache file whose [cm]times are older
		than the ones on /dev or /devices.  The change
		required adding information to Solaris device cache
		file clone lines, so the first time lsof 4.04 is
		run under Solaris it will complain about a bad
		cached clone device in a previous device cache
		file, then regenerate it.

		Added boot file path detection for SCO OSR 5 and
		above, based on information supplied by Bela.

		Fixed two bugs in DEC OSF/1 lsof -- an error in
		reporting locks and a missing continue statement
		in readdev() after a failure to open a directory.
		Jan Ole Suhr <josuhr@informatik.tu-clausthal.de>
		reported the second bug and supplied a fix.

		Fixed XFS problems with IRIX 6.2 by abandoning the
		idea that SGI will distribute XFS header files and
		defining an lsof-private xfs_inode structure.  John
		Paul Morrison <John.Paul.Morrison@MultiActive.com>
		helped develop and test the 5.3 definition.  John
		R. Vanderpool <fish@daacdev1.gsfc.nasa.gov> helped
		develop and test the 6.2 definition.

		Remove obsolete comments about common/*.frag files.

		Updated Linux lsof for Linux version 2.1.35.

4.04		April 18, 1997
Supplement	Regenerated the 4.04 distribution to correct a non-
		device-cache #define misplacement in the Solaris and
		SunOS dlsof.h.  Alexandre Oliva <oliva@dcc.unicamp.br>
		reported the problem.

4.05		April 24, 1997
		Corrected an error in 00DCACHE.

		Made sure SCO /etc/ps/booted.systems is closed.

		Based on an observation by Bela Lubkin <belal@sco.COM>
		that the lsof child had needless file descriptors
		open, closed all but the open pipes between the
		lsof parent and child.

		Decommissioned CDC EP/IX support; I no longer have a
		test system.

		Based on a suggestion from Patrick Connor
		<connor@phreak.csd.sgi.com>, added -xansi to CFLAGS
		for IRIX 5.3 and 6.[234].

		Also at Patrick's suggestion changed Configure to
		propagate exact SunOS 4.1.x version to the main
		and library Makefiles.  This allowed the sunos413
		and sunos413cc Configure abbreviations to be
		shortened to sunos and sunoscc.

		Updated obsolete argument uses (-H changed to -n)
		in count_pf.perl* and watch_a_file.perl scripts.

		Adjusted Solaris 2.6 lsof for Beta_Update with tips
		from Casper Dik <casper@holland.Sun.COM>.

		Fixed a Solaris 2.4 TCP address reporting bug.

4.06		April 30, 1997
		Added a step to the Makefile clean rules that does
		a make clean in the lib subdirectory; suggested by
		Casper Dik <casper@holland.Sun.COM>.  (Configure's
		-clean argument already did this.)

		Fixed an incorrect awk argument in the sunos*)
		Configure stanza, reported by Alexandre Oliva
		<oliva@dcc.unicamp.br>.

		Added CD9660 (aka ISO) file system support to
		FreeBSD, NetBSD, and OpenBSD with mods and help
		from Kenneth Stailey <kstailey@disclosure.com>.
		(BSDI already had CD9660 support.)  While at it,
		added file descriptor system support to BSDI and
		FreeBSD.

		Added /kern file system support to OpenBSD.  The
		support wasn't extended to BSDI, FreeBSD, or NetBSD,
		because it requires Kenneth Stailey's changes to
		/sys/miscfs/kernfs/kernfs.h.

		Updated IRIX 6.3 support after getting access to
		a test system, provided by John Paul Morrison
		<John.Paul.Morrison@MultiActive.com>.  Improved
		the handling of IRIX 5.1 and greater FIFOs.

4.07		May 12, 1997
		Based on AIX problem reports from David Capshaw
		<David.Capshaw@SEMATECH.Org>, changed the aix*
		Configure script stanza to avoid -bnolibpath for
		gcc (which the GNU loader doesn't grok) and AIX
		below 4.1.4 (where -bnolibpath hasn't been tested
		or is known to be unimplemented), and to refuse to
		use gcc for compiling lsof in AIX versions below
		4.1 (because of possible structure alignment
		problems).  Updated 00FAQ appropriately.

		Added OpenBSD support for EXT2FS.  This support
		has yet to be tested.
		
		Tested lsof under OpenBSD 2.1.

		Activated /kern file system support for NetBSD when
		Configure senses that /sys/miscfs/kernfs/kernfs.h
		defines the kern_target structure.  This support
		has not been tested under NetBSD, although it has
		been tested under OpenBSD.

		Made some simple changes to the BSDI machine.h,
		suggested by Jeffrey C. Honig <jch@bsdi.com>.

		Improved handling of alternate dialect Configure
		abbreviations -- aix and aixgcc, hpux and hpuxgcc,
		solaris and solariscc, and sunos and sunoscc.

4.08		May 23, 1997
		Cleaned up dialect Makefile's, staring with a suggestion
		from Christopher Schanzle <chris@cam.nist.gov>.

		Improved Configure's -clean processing.

		Corrected bugs in Solaris lock reporting.

		Changed NetBSD Configure stanza to put -I/usr/include
		before -I/sys.

4.09		June 1, 1997
		Adjusted for latest FreeBSD 3.0 release.  This
		required adding a new kernel name cache module for
		reading BSD-form hashed kernel name cache entries,
		rnmh.c, to the lsof library, and adding a #define
		to each machine.h to select it.

		Activated rnmh.c for BSDI 2.1, BSDI 3.0, NetBSD
		1.2, and OpenBSD 2.1.

4.10		June 8, 1997
		Adjusted for Linux 2.1.x (x > 35) kernels with
		hashed task structure pointers.  Marty Leisner
		<leisner@sdsp.mc.xerox.com> and Jonathan Sergent
		<sergent@io.com> tested the adjustment.

		Replaced readdev() stat() calls with lstat() to
		reduce device table and cache entries with the same
		device number and inode values.  Added code to
		remove all remaining duplicates.  This fixes a
		Linux problem reported by Jonathan Sergent and
		makes device node name output predictable.

		Corrected a bug in UnixWare stream file handling
		that prevented searching for the stream file by
		its associated character device name.

		Added Pyramid code to determine Reliant UNIX clone
		major device number differently from that of DC/OSx.

4.11		June 12, 1997
		Changed Configure to sense that the PTX inp_[fl]addr
		members of the inpcb structure of <netinet/in_pcb.h>
		have a struct type and set HASINADDRSTR for use in
		PTX dnode.c and dsock.c tests.

		Changed PTX version 4.1.4 tests to use 4.1.3 instead.
		Carson Wilson <carson@mcs.com> reported the need
		to do this and tested the change.

		Fixed a block device table indexing bug in lib/rdev.c,
		reported by Carson Wilson.  The same bug was squashed
		in pyramid/ddev.c.

		Added code to the Pyramid Reliant UNIX kread()
		function to compensate for an address boundary
		error in the kernel's /dev/kmem driver.

		Verified that lsof compiles and works under AIX
		4.2.1.  Added an AIX test for the presence of NFS
		header files, defined HAS_NFS and adjusted AIX
		dialect sources accordingly.

		Based on a suggestion from Gaylord Holder
		<holder@phy.ucsf.EDU>, added DEC OSF/1 code to
		auto-detect the booted file, whence kernel symbol
		addresses are obtained.

4.12		June 24, 1997
		Corrected a device number sign extension problem
		in the reading and writing of device cache file.
		The problem was reported by Bela Lubkin <belal@sco.com>
		and he suggested a fix.

		Fixed an SCO stream device lookup problem.  The
		report and solution came from Bela Lubkin

		Enhanced the Configure script to enable cross-
		configuration of lsof, based on suggestions from
		Marty Leisner <leisner@sdsp.mc.xerox.com>.  A new
		documentation file, 00XCONFIG, describes the process.

		Made Pyramid OBJFS support conditional on the
		presence of supporting header files.  Corrected
		the Pyramid MkKernOpts script so it generates the
		necessary -D's for the Nile/Jolt architecture.
		Richard Coley <rcoley@pyra.co.uk> helped.

		Added another IRIX xfs_inode variant for 6.2, 32
		bits, no XFS rollup patch.

		Tested under UnixWare 2.1.2.

4.13		July 9, 1997
		Taught Pyramid lsof to grok ttyfs vnodes with help
		from Richard Coley <rcoley@pyra.co.uk>.  Fixed some
		minor bugs in Pyramid FIFO reporting.  Eliminated
		use of the Pyramid UCB compatibility library at
		Richard's suggestion.

		Eliminated reporting of "strange" inode numbers
		for SCO OSR 3.2v5.0.x HPPS files with help from
		Bela Lubkin <belal@sco.com>

		Modified port to service name lookup to use a small
		number of getservbyport() calls before reading the
		entire map with getservent().  Changed port reporting
		to represent a zero as `*' to be consistent with
		other prt number reporting tools like netstat.
		Casper Dik <casper@holland.Sun.COM> suggested these
		changes -- the getserv*() one to improve performance
		for large NIS service name maps.

		Changed all readdev() functions to make the absence
		of block devices a warning instead of a fatal error
		after Brian Redman <ber@ms.com> reported his IRIX
		6.4 system had no block devices.  (It really did
		have block devices, but readdev()'s lstat() use
		caused it to miss them in a directory symbolically
		linked from /dev/dsk->/hw/disk.)  Fixed Brian's
		real problem by changing the IRIX readdev() to use
		stat() on /dev nodes if a Configure test shows /hw
		is readable.  Extended the potential to do the same
		to all readdev() functions.

		For consistency and convenience changed some
		Configure abbreviations and dialect subdirectory
		names:  "decosf" abbreviation and "osf" dialect
		subdirectory name to "du"; "netbsd" dialect
		subdirectory name to "n+obsd"; "next3" abbreviation
		and "next" dialect subdirectory name to "ns"; "sco"
		abbreviation and dialect subdirectory name to "osr";
		"sgi" dialect subdirectory name to "irix"; and
		"unixware" abbreviation and dialect subdirectory
		name to "uw".

		Added #if/#endif clauses to the AIX rmdupdev()
		function to avoid clone processing for AIX versions
		less than 4.1.4.  The problem was reported by Toralf
		Foerster <toralf.foerster@io-warnemuende.de>, who
		supplied corrective code.

		Added support for new style NetBSD inode with i_ffs
		and i_e2fs union members.

		Improved Configure and 00FAQ information on Digital
		UNIX configuration subdirectory with suggestions
		from Brad Krebs <brad@EECS.Berkeley.EDU>.

4.14		July 22, 1997
		Reorganized the Solaris handling of the inode
		structure header file, ufs_inode.h, to eliminate
		VxFS structure definition conflicts for Solaris
		2.4, based on information from Greg Earle
		<earle@netbsd4me.jpl.nasa.gov>.

		Cleaned up some typos and confusion in Configure's
		help output, based on comments from Bela Lubkin
		<belal@sco.com>

		Added a 00DIALECTS file, containing UNIX dialect
		version numbers, that can be used by Configure and
		the man page.

4.15		August 15, 1997
		Aligned `Configure -help` output better.  Removed
		Configure's 2.6 Beta test adjustments.

		Added improved Solaris VxFS configuration and
		handling, based on information from Greg Earle
		<earle@netbsd4me.jpl.nasa.gov>.

		Added socket state -- TCO or TPI -- for socket
		files at the suggestion of Ian Fitchet
		<I.D.Fitchet@ftel.co.uk>.

4.16		September 25, 1997
		Added reporting of TCP/TPI queue lengths and window
		sizes ala netstat to NAME column.  Added -T option
		to select or de-select TCP/TPI info reporting.
		(Window sizes are only reported for Solaris.)
		Fixed anomalies along the way in SIZE/OFF processing
		for some dialects.

		Fixed service name argument processor to allow
		minus signs as part of the name.  Consequently this
		disallows names with embedded minus signs from
		being specified as the start of a range.

		Added 00FAQ entries explaining why lsof won't find
		a file being edited with vi, why window sizes aren't
		reported for all dialects, and what the "no more
		information" message means.

		Forced Pyramid CC to be /usr/ccs/bin/cc to avoid
		accidental use of the BSD variant in /usr/ucb/cc.

		Added support for Linux glibc2, including a Configure
		test; cross-Configure support (00XCONFIG); and much
		unfortunate and risky sleight-of-hand in lsof Linux
		dialect header and source files, forced upon lsof
		by incompatibilities between Linux kernel and glibc2
		header files.

		Included in scripts/identd.perl5 a Perl 5 implementation
		of an identd server, using lsof, provided by Kapil
		Chowksey <kchowksey@hss.hns.com>.

		Updated IRIX 6.4 xfs_inode guess.

4.17		October 14, 1997
		Added -V option for verbose search result reporting.
		Verbose reports are prepared for failure to locate
		file names, command names, Internet addresses or
		files, login names, NFS files, PIDs, PGIDs, and UIDs.

		Augmented Linux NFS file test to cope with kernels
		whose NFS code is in a loadable module.  Need for
		the test was pointed out by Jonathan Sergent
		<sergent@csociety.ecn.purdue.edu>.  The change
		required that Linux have private dmnt.c source,

		Completed a Linux 2.1.57 port on a system provided
		by Jonathan Sergent.

4.18		October 25, 1997
		Eliminated memory leaks in alloc_lfile(), lkup_port(),
		and NEXTSTEP's process_text() function.

		Added recognition of OpenBSD 2.2 in Configure,
		supplied by Kenneth Stailey <kstailey@disclosure.com>.

		Consolidated print_file() functions to use the one
		in lib/prtf.c.  Made it configurable and changed
		it to size print columns dynamically.

		!!! WARNING !!!

		WITH DYNAMICALLY SIZED PRINT COLUMNS LSOF 4.18
		PRODUCES OUTPUT SIGNIFICANTLY DIFFERENT FROM THAT
		OF PREVIOUS REVISIONS.  LINES ARE GENERALLY SHORTER
		AND THERE IS GENERALLY LESS BLANK SPACE BETWEEN
		COLUMNS AND THE ITEMS IN THEM.  THERE ARE NO LONGER
		ANY SPACES BETWEEN DEVICE NUMBER ELEMENTS, ONLY
		COMMAS.

		!!! WARNING !!!

		Added special types and print specification modifiers
		for file size and offset to handle UNIX dialects
		with 64 bit sizes and offsets.  Paul Eggert
		<eggert@twinsun.com> reported the need for this
		addition.

		With Paul Eggert's help picked lint from the lsof
		library, the main level lsof sources, and the Sun
		dialect sources.

		Added documentation, including the file 00LSOF-L,
		about the lsof-l LISTSERV.

		Added support for Reliant UNIX on the RM600.  Bob
		Passarella <rmpassar@pyramid.com> supplied the
		changes.  Kevin Smith <kevin@pyramid.com> helped
		arrange test systems.  While incorporating Bob's
		changes, modified lib/rnch.c to handle kernel ncache
		structs whose name is accessed via a char *, rather
		than in a char array.

		Changed #include order of <sys/socketvar.h> for
		Solaris 2.x.  W. Richard Stevens <rstevens@kohala.com>
		pointed out the need to do this.

4.19		October 30, 1997
		Changed Pyramid Reliant RM600 proc scan to skip
		SSYS (p_flag) processes, since they don't seem to
		have a readable u_cdir vnode.

		Enabled Pyramid Reliant UNIX kread() work-around
		for DC/OSx, too, since its read(/dev/kmem) kernel
		driver seems to share the page boundary bug this
		work-around circumvents.

		Changed SzOffFtm_d and SzOffFtm_dv (new formats at
		4.18 to print size and offset) from signed to
		unsigned.  Setting them signed at 4.18 was an
		oversight.

		Plugged a memory leak that caused the loss of 130
		bytes per repeat-mode pass.  Fixed it with a simple
		work-around in main().  Lionel Cons <Lionel.Cons@cern.ch>
		reported the leak.

4.20		November 11, 1997
		Tested under BSDI 3.1.

		Added support for Reliant UNIX Mesh IPC files with
		help from Billy Ho <bho@pyramid.com>.

		Added support to Digital UNIX lsof that uses the
		libmsfs tag_to_path() function (when it exists) to
		look up AdvFS path names.  The idea and sample code
		came from Dean Brock <brock@cs.unca.edu>.  Converted
		Dean's code into more general purpose support for
		private name cache lookups via the HASPRIVNMCACHE
		#define in the dialect machine.h file and code
		conditional on it in the printname() function.

		Taught Digital UNIX lsof to recognize NFS3 file
		systems.  Corrected Digital UNIX lsof DEVICE column
		alignment.

4.21		December 1, 1997
		Squashed bug, introduced at revision 4.18, that
		resulted in double reporting of each selected PID
		when terse mode (-t) was specified.

		Corrected minor bug, also introduced at 4.18, that
		might cause an extra print_proc() pass when one
		PID has been specified.

		Added -R to lsof options in scripts/idrlogin.perl*.
		The option should have been there -- it was supposed
		to be mandatory for PGID reporting -- but a bug,
		corrected in revision 4.18, previously made -R
		unnecessary.

		Enabled configuring for BSDI BSD/OS 4.0 per a
		suggestion from Jeff Honig <jch@bsdi.com>.

		Enabled replacement of scoff_t with off64_t (scoff_t
		is used to type r_size and r_localsize in the rnode
		struct) for IRIX 5.3 systems that have the NFS
		kernel rollup patch (1477).  This compensates for
		SGI's failure to distribute an updated <sys/fs/rnode.h>
		with their patch.

		Validated under Linux 2.0.3[12], Linux 2.1.64, and
		NetBSD 1.3.

		Added FreeBSD root directory reporting, courtesy
		of Dan Nelson <dnelson@emsphone.com>.

4.22		December 15, 1997
		Made adjustments for Linux 2.1.7[02].

		Improved NAME information for Linux UNIX domain
		sockets.

		Added option +|-M to control the reporting of
		portmapper registration information in square
		brackets after the TCP or UDP port or service name.
		Kenneth Stailey <kstailey@disclosure.com> suggested
		the feature and provided sample code from OpenBSD.
		Reporting is disabled by default in the distribution
		and may be enabled with +M; if lsof is compiled
		with HASPMAPENABLED (e.g., from machine.h), reporting
		will be enabled by default and can be disabled with
		-M.

		Changed the -w option to +|-w to match the syntax
		of the +|-M option and to eliminate any options
		that flip meaning when a symbol is defined at
		compile time.  For both +|-M and +|-w, specifying
		`-' when the default state is disabled or specifying
		`+' when the default state is enabled causes no
		problems.

	!!!WARNING  The -w option has changed in lsof 4.22.  WARNING!!!

		Made the +|- prefix legal for most options, but
		didn't document it in the man page or help panel.
		Most options that disable something -- e.g., -b,
		-C, -n, -P -- now disable when the prefix is `-'
		and enable when it is `+'.  Since the states these
		options disable are enabled by default, I chose to
		avoid documentation complexity and confusion by
		not mentioning that they can be used with the `+'
		prefix.

		Condensed the help panel.

		Made sure Digital UNIX Configure stanza puts normal
		include path (e.g., /usr/include) before system
		include paths.

		Added IPX socket information reporting to Linux
		with help from Jonathan Sergent <sergent@purdue.edu>.

4.23		January 16, 1998
		Fixed conflict arising from the quondam replacement
		of the Sun Solaris <netdb.h> with a BIND/BSD version.

		With help from Jonathan Sergent <sergent@purdue.edu>
		developed a /proc file system based Linux lsof.
		It needs some Linux 2.1.x release to work -- I'm
		not sure which, but I tested under 2.1.72, 2.1.76,
		and 2.1.79.  The Configure script selects special
		sources for this lsof, so the full lsof distribution
		now contains both /dev/kmem and /proc based sources
		for Linux lsof.  An optional kernel mod, written
		by Jonathan, enhances the /proc-based lsof ability
		to recognize IPX socket files.  Reorganized and
		augmented the Linux sections in 00FAQ to explain
		the two types of Linux lsof.

		Defined DOSTAT_FUNCTION for dostat() in misc.c to
		select the function, stat() or lstat(), it will use.
		DOSTAT_FUNCTION is normally undefined, defaults to
		lstat(), and is only defined for the /proc-based
		Linux lsof in its dlsof.h.

		Made conditional on the presence of IRIX 6.4 XFS
		rollup patch #6 an XFS node change introduced in
		revision 4.16.   Identified the patch with help
		from John R. Vanderpool <fish@daacdev1.gsfc.nasa.gov>.

		Added NFS node compensation for NetBSD 1.3.  The
		code and suggestion for it was supplied by Jean-Luc
		Richier <richier@imag.fr>.

		Added diagnostic messages to the /dev/kmem-based
		Linux Mksrc script to report errors during the
		construction of the kernel name cache header file,
		kncache.h.  Added 00FAQ information on kncache.h.

		Added a new Linux test host, running 2.0.33 and
		GlibC, provided by Steve Logue <stevel@mail.cdsnet.net>.

		Ported to PTX 4.1.3 and 4.4.2.  Adjusted lib/rnch.c
		for 4.4.2 to allow customization f additional ncache
		struct element names.

4.24		January 28, 1998
		Changed /proc-based Linux lsof offset test to use "/"
		instead of "/etc/passwd".

		To assist Jim Mintha <jim@geog.ubc.ca> with the
		packaging of lsof for Debian Linux, added a
		DEBIAN_LINUX_LSOF #define to trigger the activation
		of special system map file location code in the
		/dev/kmem-based dproc.c.

		Applied modification to dialects/bsdi/dlsof.h from
		Ingimar Robertson <iar@skyrr.is>, enabling lsof to
		compile for BSDI BSD/OS 2.0.

		Corrected a documentation error in 00DCACHE, pointed
		out by Thomas Anders <anders@hmi.de>.  The error was
		created when the -V option was added at lsof 4.17.

		Made IRIX 5.3 through 6.3 lsof aware of IRIX SCSI
		tape devices (e.g., /dev/tape).  Dave Olson of SGI
		and Randolph J. Herber of FNAL provided valuable
		advice, and Igor Schein <ischein@air-boston.com>
		helped test.

		Added a machine.h symbol (NEVER_HASDCACHE) that
		prevents Customize from offering to change HASDCACHE.
		The symbol may appear anywhere in machine.h --
		e.g., in a comment.  Included the symbol in a
		comment of the HASDCACHE section of the /proc-based
		Linux lsof machine.h, and accompanied it with
		warnings against #define'ing HASDCACHE.  Did the
		same thing for WARNDEVACCESS (NEVER_WARNDEVACCESS
		is the suppressant.)

4.25		February 7, 1998
		Corrected an IRIX mis-cast of file offset (position).
		Igor Schein <ischein@air-boston.com> reported the
		problem.  This was offered as a patch to 4.24.
		Picked some lint Igor pointed out.

		At Igor's suggestion added an optional decimal
		digit size argument to the -o option.  This argument
		specifies how many file offset decimal digits can
		follow "0t" before lsof switches to a "0x..." form.
		The argument size specification doesn't count the
		two characters of the "0t".  A size of 0 means
		unlimited.  The default is OFFDECDIG (8), preserving
		compatibility with existing lsof output; it can be
		changed by the lsof builder.  When size is specified
		with -o it does not force offset display; -o without
		a size still must be used to do that.

		Added an IRIX 6.2, 32 bit system, XFS node patch,
		courtesy of Ulrich Bernhard <rzubu@rzu.unizh.ch>.

		For my own convenience enabled Configure to use
		/usr/local/bin/gcc for NEXTSTEP.  This allows
		circumvention of a gcc 2.8.0 ranlib problem on
		my test 3.1 `040 cube.

		Added flags recommended by the RISC/os and Ultrix
		compilers for the updated (and longer) main.c.

		Updated FreeBSD cd9660_node.h Configure test.

4.26		February 17, 1998
		Added shared process group processing for IRIX 5.3,
		and IRIX 6.1 and above, based on investigation of
		a bug report from Igor Schein <ischein@air-boston.com>.
		Igor helped test this addition.

		Improved handling of file system name arguments.
		It's now done in a manner similar to fuser.  The
		-f argument forces path names to be considered as
		simple files, rather than as file system names.
		The +f flag forces them to be considered as file
		system names.  Normally path arguments are considered
		file system names when they match a mounted-on
		directory in the system's mount table, or when they
		match a mounted file system's block device.  Igor
		Schein helped test this change.

		Igor also suggests that the proper compilation of
		the IRIX 6.4 proc structure after patch 2536 has
		been installed may need -DPIOMEMOPS.  So lsof's
		MkKernOpts script was updated to propagate that
		option from CCOPTS in /var/sysgen/system/irix.sm,
		even though patch 2536 doesn't add -DPIOMEMOPS to
		it.  Added a 00FAQ item on this patch.

		Added a fatal warning message about names forced
		to be file system names (with +f) that have no
		match in the mount table.

		Improved the -V message for files and file systems
		for which no open files were found.  Added reporting
		of /proc file and file system search failures.

		Did some code reorganization to combine the multiple
		ck_file_arg() functions into one.  Moved the new
		function from the library to the top level and put
		it in arg.c; moved the usage function from arg.c
		to a new top-level source file, usage.c, to balance
		top-level source file size.  The new usage.c depends
		on version.h; arg.c no longer does.

		Added flag recommended by the DU compiler for the
		updated (and longer) main.c.

4.27		March 6, 1998
		At the request of Igor Schein <ischein@air-boston.com>
		added a conditional repeat mode option, using the
		`+' prefix to the `r' option.  +r operates as does
		-r with the exception that it exits the first time
		no open files have been listed during a cycle.
		The exit code will be zero when any open files have
		been listed; one, if none were ever listed.

		Ported lsof to HP-UX 11.0 with the help of Richard
		Allen.  This port hasn't been tested on a 64 bit
		kernel; I'm sure it won't work there without more
		mods.  It may not work on PA 2 architectures; I've
		only tested it under PA 1 and a separate, busy
		tester reported PA 2 problems that I've been unable
		to investigate.

		In anticipation of getting access to a 64 bit HP-UX
		kernel and the pending start of the Solaris 2.7
		Beta test (It will have 64 bit kernel addressing.),
		started adding support for 64 bit kernel pointers.
		This includes: ubiquitous use of the KA_T cast
		for kernel pointers; a format to print them,
		KA_T_FMT_X; a function to print them, print_kptr();
		and modifications to most kernel-related functions
		-- e.g., process_file(), process_node(),
		process_socket(), readvfs() -- to process kernel
		addresses as KA_T types.

		Fixed minor bug in handling path name arguments
		that end with a `/'.

		Removed support for RISC/os; its test system is no
		longer available.

		Made modifications to insure that lsof output
		doesn't contain non-printable characters.  All such
		characters are now printed in the printf form
		"\x%02x".  Several new common functions were
		installed in misc.c to support "safe" printing.
		This second major modification in 4.27 to common
		and dialect code could have introduced bugs not
		yet detected.

4.28		March 10, 1998
		Refined unprintable format to use \b, \f, \r, \n,
		\t, and ^* (for CTRL) forms.  Corrected omission
		of safestrprt() use for field output command name.
		These changes were offered as patches to 4.27.

		Made space an unprintable character (\x20) in the
		COMMAND column; printable elsewhere, including the
		NAME column, field output, and error messages.

		Made sure FD column is parseable as a single entity
		-- i.e., has no embedded space.  Thus, if the access
		mode is unknown but there is a known lock mode, (a
		very rare case) the access mode will be printed as
		`-'.

		Picked lint with gcc 2.8.0 under Solaris 2.6.

		With the help of Dave Olson of SGI identified a
		proc struct element that should have been added to
		<sys/proc.h> by IRIX 6.4 patch 2536.  Added a
		work-around for it to the lsof Configure script.
		Igor Schein <ischein@air-boston.com> identified
		that the patch caused a proc structure length
		complaint from lsof.  Removed an obsolete 00FAQ
		item on the patch, installed at lsof 4.26, explaining
		that no solution was yet available.

		Added a 00FAQ item on how BIND installs its own
		header files, including <netdb.h>, which may cause
		the rpcent struct definition to vanish.  Solaris
		has an automatic lsof work-around, but that hasn't
		been (and probably can't be) propagated to all
		dialects supported by lsof.  The 00FAQ item recommends
		re-installation of the vendor header files that
		BIND has replaced.  (Others include <rpcent.h>,
		<sys/bitypes.h>, and <sys/ctypes.h>.)

		Made AIX AFS fixes.

4.29		March 26, 1998
		Corrected bug in Internet address matching.  The
		matching formerly stopped if the foreign address
		matched, thus failing to check the local address
		for a match.  That led to a possible false "Internet
		address not located" warning (i.e., in response to
		-V) about the local address, when both foreign and
		local addresses were specified with -i.  This
		correction was offered as a patch to 4.28.

		Changed readmnt() usage in an attempt to defer
		mount readlink() and stat() delays until they are
		necessary.

		Corrected two bugs in the Digital UNIX readdev()
		function.  Made the correction available as a patch
		to 4.28 and regenerated the 4.28 DU binaries.

		Added a missing argument to a print-kptr() call in
		the HP-UX dsock.c.  The missing argument causes a
		fatal gcc error.  The problem was reported by Eyal
		Shaynis <eyal.shaynis@telrad.co.il>.  The fix was
		offered as a 4.28 patch.

		Adjusted for Digital UNIX 4.0D; the spec_node
		structure is now defined in <sys/specdev.h>.  Kris
		Chandrasekhar <Kris.Chandrasekhar@digital.com>
		identified the need for the adjustment.

		Incorporated a bug fix from Brian McAllister
		<mcallister@mit.edu> to the DU readmnt() function.
		This fix was offered as a patch to 4.28.

		Added "safe" printing to a SunOS clone device error
		message.

		Corrected bug in tabling of Linux /proc-based lock
		info.

		Corrected bug in handling of SunOS TLI streams.
		Dan Farmer <zen@trouble.org> reported the problem.

		Added a Solaris 2.6 work-around to keep the BIND
		<sys/bitypes.h> from colliding with the Solaris
		<sys/int_types.h>.

		Strengthened the Configure test for /proc-based
		Linux lsof, based on a report from Marty Leisner
		<leisner@sdsp.mc.xerox.com>.

		Tested on OpenBSD 2.3.

		Made AIX changes that allow use with 3.2.5.  The
		changes were suggested and tested by Brett Hogden
		<hogden@rge.com>.

		Added Solaris 2.6 AFS support.  Disabled reporting
		of some node numbers for Solaris 2.5 and above open
		AFS files.  The node number computation algorithms
		used for SunOS 4.1.x and Solaris less than 2.5 no
		longer always work under Solaris 2.5 and above.

4.30		April 9, 1998
		Corrected a pid structure member naming error for
		UnixWare < 2.1.2.  The problem was reported by
		Richard van Meurs <vanmeurs.anva@atriserv.nl>.  He
		supplied the correction.  This was offered as a
		patch to 4.29.

		Had a report from Igor Schein <ischein@air-boston.com>
		that IRIX 6.4 patch 2839 is another SGI kernel
		patch, along with 2536, that changes the size of
		the proc structure in the kernel without changing
		the proc structure in <sys/proc.h>.  Upon further
		investigation found that the effect of these patches
		on the proc structure is not consistent.  Therefore,
		dropped the Configure patch test for IRIX 6.4 and
		made the code in irix/dproc.c slightly more tolerant
		of proc structure size differences for IRIX 6.4.
		Igor help test the change.

		Corrected Solaris >= 2.5 AFS inode number generation.
		Craig Everhart <Craig_Everhart@transarc.com> helped
		find the cause of the problem.  This was offered as
		a patch to 4.29.

		Refined the Linux /dev/kmem-based glibc evasion
		for the timeval structure to make it work with
		glibc version 2.0.7.  This required defining a new
		global symbol, TIMEVAL_LSOF, default timeval, that
		the /dev/kmem-based Linux lsof can set to its
		private glibc timeval name, distinct from the kernel
		timeval name.

		Added support for Alpha to the /dev/kmem-based
		Linux lsof.  Alexandre Oliva <oliva@dcc.unicamp.br>
		provided a test system.  Added an item to 00FAQ
		about lsof, the Alpha processor, and Linux.

		Added a 00FAQ item about lsof year 2000 compliance.
		Basically it says lsof is probably compliant,
		because its only date or time computations are done
		with time_t values, but I haven't done any specific
		Y2K validation.  I don't have plans to do any.

		Added support for UnixWare 7.  Chris Daniels
		<chrisd@dlpco.com> provided a test system and Don
		Draper <dond@sco.COM> provided technical information.
		Added BFS and SFS file system support to lsof for
		UW 2.1.[12] and 7.

		Updated Solaris VxFS support for VxFS 3.2.1.  Greg
		Earle <earle@netbsd4me.jpl.nasa.gov> reported the
		need for the update.  Greg and Roger Klorese
		<rogerk@veritas.com> provided technical information.
		Scott McClung <mcclung@primenet.com> tested.

		Changed IRIX XFS patch detection in anticipation of
		learning there are multiple XFS patches for IRIX 6.4
		that require different versions of the lsof-invented
		xfs_inode structure.

4.31		April 21, 1998
		Added a VxFS #if/#endif wrap to a section of the
		HP-UX dnode.c that wasn't properly protected.  The
		problem was reported by  Peter Klosky <PKlosky@bdm.com>.
		This was offered as a patch to 4.30.

		Added support for Solaris 2.7 (first Beta release).
		Mike Sullivan <Mike.Sullivan@Eng.Sun.COM> provided
		technical advice and helped test.  Charles Stephens
		<cfs@jurassic.eng.Sun.COM> also helped test.

		Fixed bug in /proc-based Linux that caused it to
		access /proc/mounts excessively.  Marty Leisner
		<leisner@sdsp.mc.xerox.com> provided a syscall
		trace that identified the bug.  The fix was offered
		as a patch to 4.30.

		Adjusted the IRIX 6.4 private structure definition
		for the XFS node to accommodate patch 2970.  Igor
		Schein <ischein@air-boston.com> identified the
		patch and the required adjustment.
	
4.32		May 11, 1998
		Corrected Solaris 2.7 code for reporting PCFS
		(floppy disk) node numbers.  Casper Dik
		<casper@holland.sun.com> supplied the fix.  The
		fix was offered as a patch to 4.31.

		Corrected a bug in conditional repeat mode handling
		pointed out by Igor Schein <ischein@air-boston.com>.
		This was offered as a patch to 4.31.

		Improved reporting of AIX open(/dev/memory device)
		errors.

		Corrected a Solaris < 2.5 KA_T declaration error,
		pointed out by Robert Kiessling <robert@easynet.de>.
		Changed KA_T from a #define to a typedef for all
		dialects to prevent future problems of this kind.

		Changed the sample Perl 5 script big_brother.perl5
		to report a four digit year from localtime().

		Added support for AIX 4.3[.1].  Bill Pemberton
		<wfp5p@tigger.itc.virginia.edu> provided a test
		system.  Andrew Kephart <akephart@austin.ibm.com>
		and Tom Weaver <tvweaver@austin.ibm.com> provided
		technical assistance.  Niklas Edmundsson
		<nikke@ing.umu.se> did 4.3.1 testing.

		Added -qmaxmem option to CFLAGs for an AIX compilation
		with an xlc version 4.x compiler.

		Adjusted Linux socket handling for changes in the
		AX25 members of the sock struct.   Richard Green
		<rtg@tir.com> pointed out the problem.  Tested
		/dev/kmem-based lsof under Linux 2.0.34.

4.33		May 22, 1998
		Added generic IPv6 support to common lsof sources
		and specific IPv6 support to AIX sources.  Andrew
		Kephart <akephart@austin.ibm.com> supplied the
		additions and helped with testing.  Bill Pemberton
		<wfp5p@tigger.itc.virginia.edu> provided a test
		system.  The modification affected sources for
		every dialect, whether it supports IPv6 or not, by
		changing the interfaces to the common Internet
		address function ent_inaddr().

		Added support for the NetBSD UVM virtual memory
		system.  Paul Kranenburg <pk@cs.few.eur.nl> supplied
		technical details.

		Bracketed HP-UX 11 use of <sys/spinlock.h> with
		#if/#endif _KERNEL.

		Corrected printing of PCB address in DEVICE column
		for IRIX.

4.34		June 26, 1998
		Updated 00FAQ to discuss TCP and UDP ports private
		to the AIX kernel and 00README to describe how ACLs
		can be used to give lsof permission to read the
		kernel memory devices.  Add information to 00FAQ
		and 00README about other OpenBSD architectures
		where lsof is reported to compile and run.  Added
		section to 00FAQ discussing how an incorrect loader
		path environment variable value can prevent lsof
		from loading correctly.

		Improved Solaris namefs and doorfs support so that
		it is now possible to search for an open VDOOR file
		by the path name of its fattached file system
		object.  Igor Schein <igor@txc.com> requested the
		ability to do such a search.  Even with the change,
		lsof can't always identify path names for open
		VDOOR files.

		Also at Igor's request, improved reporting of
		information on open Solaris VCHR files that share
		a common vnode, and Solaris UNIX domain socket
		files.

		Corrected print_kptr() argument error in PTX dnode.c,
		reported by Mark Price <mprice@sequent.com>.
		Compensated for ncache element naming differences,
		introduced at PTX 4.4.2; Kurtis D. Rader
		<krader@sequent.com> reported the problem.

		Changed output column title from INODE to NODE to
		better reflect the column's contents of node IDs
		for more than just inodes.

		Improved Configuration and processing for Solaris
		AFS.  Corrected AIX AFS 3.4 afs_rwlock_t simulation.

		Corrected a cast problem with two AIX knlist()
		calls, thus quieting an AIX 4.2.1 compiler argument
		type warning.  Jon Champlin <champlin@us.ibm.com>
		reported the problem.

		Added support to most dialect versions (exception:
		/proc-based Linux) to warn when the identity of
		the kernel where lsof was compiled doesn't match
		the running identity.  The warning can be suppressed
		with -w.  Note: determining AIX state requires
		calling oslevel, a potentially slow operation.
		Jon Champlin <champlin@us.ibm.com> suggested this
		addition.

	!!!! WARNING !!!!    !!!! WARNING !!!!    !!!! WARNING !!!!

		Those using the lsof cross-configuration capability
		(see 00XCONFIG), should be aware that the kernel
		identity test feature introduces two new basic
		cross configuration environment variables, LSOF_ARCH
		and LSOF_VSTR.

	!!!! WARNING !!!!    !!!! WARNING !!!!    !!!! WARNING !!!!

		Identified a situation where a Solaris UNIX domain
		socket name is known and can be searched for by
		name; added the necessary code.

4.35		July 17, 1998
		Made the kernel identity check an option with the
		HASKERNIDCK #define in machine.h.  Enabled altering
		of HASKERNIDCK with the Customize script.  Added
		a clause to the help output that indicates the
		build-time HASKERNIDCK status.

		Added more information to the NAME column for
		Solaris UNIX domain sockets.  Made them searchable
		by their clone device path name.  Igor Schein
		<igor@txc.com> requested this.

		Completed the HP-UX 11 port with support for its
		optional 64 bit kernel.  Rich Rauenzahn
		<rrauenza@cup.hp.com> provided a test system.
		Corrected errors with HP-UX 11 lock reporting and
		private kernel structure and type definitions.
		Added support for HP-UX NFS3 files.

		Limited mount table warnings -- e.g., when -b is
		used -- to one set per mount point.

		Fixed some mount table scanning and usage bugs,
		including one in Solaris, reported by Kjetil Torgrim
		Homme <kjetilho@ifi.uio.no>.

4.36		August 4, 1998
		Made corrections and additions to IPv6 support and
		to AF_ROUTE socket handling, supplied by Jean-Luc
		Richier <Jean-Luc.Richier@imag.fr>.  Jean-Luc's
		additions provide IPv6 support for the Inria IPv6
		implementations on FreeBSD and NetBSD.

		Fixed two Solaris 2.5, 2.5.1, 2.6 and 2.7 TCP and
		UDP host name or IP address reporting bugs, reported
		by James Mathiesen <James-Mathiesen@deshaw.com>.
		This fix was offered as a patch to 4.35.

		Updated the Customize script to cause ENTER to use
		all defaults.  Amir J. Katz <amir@ndsoft.com>
		suggested this and helped test the changes.

		Updated Solaris ICMP and IP stream handling, based
		on a report from Igor Schein <igor@txc.com>.

		Fixed a bug in the Digital UNIX mount table handling,
		reported by Bob Ward <bward@thehartford.com>.
		While working on the bug, found and updated some
		obsolete AdvFS code.  This fix was offered as a
		patch to 4.35.

4.37		September 15, 1998
		Deactivated SGI IRIX support and archived revision
		4.36 sources and binaries in pub/tools/unix/lsof/OLD.

		Improved performance of FD searching.  This was
		offered as a patch to 4.36.

		Amir J. Katz <amir@ndsoft.com> pointed out that
		ranlib isn't needed for AIX or Solaris.  Made
		appropriate Configure script changes.

		Fixed a file offset reporting bug for HP-UX VCHR
		and VBLK device nodes located on a VxFS root.  Doug
		Siebert <douglas-siebert@iowa.edu> reported the
		bug.  The fix was offered as a patch to 4.36.

		Resolved an HP-UX root device name reporting bug,
		partly caused by an out-dated local copy of the
		<sys/mount.h> mount structure, by generating a
		local header file with the structure that can be
		compiled without needing _KERNEL defined.  Doug
		Siebert also reported this bug.

		Changed some dialect source code -- Digital UNIX,
		Solaris, SunOS, and UnixWare -- to make more
		consistent with ps the user ID lsof reports in the
		USER column.  Added a 00FAQ entry about it.  Igor
		Schein <igor@txc.com> reported the Solaris and
		SunOS lsof inconsistencies with what ps(1) reports.

		Ported lsof to Pyramid ReliantUNIX 5.44.

		Added brackets as comments to case, do, done, else,
		endif, esac, if, and while statements in Configure
		to assist in navigating its clauses.

		Added more Linux 2.0.x glibc work-arounds.

		Added support for UnixWare 7.0.1.

		Ralph Forsythe <ralph@contact-paging.com> provided
		a new FreeBSD test system.

4.38		November 25, 1998
		Added support for recent FreeBSD 3.0 distributions.
		A 3.0 test system was provided by David O'Brien
		<obrien@NUXI.com>.  This was offered as a patch
		to 4.37.

		Updated the scripts/idrlogin.perl* files to look
		for sshd processes in addition to rlogind and
		telnetd ones.

		Added support for DU 5.0 Beta.  Berkley Shands
		<berkley@cs.wustl.edu> provided a test system.

		Added support for OpenBSD 2.4 with changes supplied
		by Kenneth Stailey <kstailey@disclosure.com>.

		Changed the Solaris 2.7 tests and documentation to
		Solaris 7.

		Made some changes to the header files for NEXTSTEP
		3.3 and added support for OPENSTEP 4.x with help
		from Michael A. Hovan III <mhovan@BLaCKSMITH.com>
		and Carl Lindberg <Carl_Lindberg@BLaCKSMITH.com>.
		The combined dialect subdirectory is named n+os.
		One of Carl's changes propagates RC_CFLAGS to the
		library Makefile.  Timothy J. Luoma <luomat@peak.org>
		helped test under NEXTSTEP 3.3 and OPENSTEP 4.2.

		Made UW 7.x version sensitive to the presence of
		ptf7038.  Added peer PCB address to Unix domain
		socket Name column, even when a path name has been
		located.  Information for these changes was supplied
		by Francis Le Bourse <flebourse@intelcom.fr>.  Lee
		Penn <lee@dlpco.com> provided a test system.

		Tested lsof under OSR 5.0.5 on a test system also
		provided by Lee Penn.

		Made path name argument processing more tolerant
		of errors per a suggestion from Julian Gordon
		<julian@cadence.com>.

		Acquired a new UnixWare 2.x test system, generously
		provided by Computer Classroom, Inc. -- Matthew
		Thurmaier <matt@compclass.com>, Ken Laing
		<ken@compclass.com>, and Andrew Merril
		<andrew@compclass.com>. Updated Configure to accept
		a UnixWare version of 2.1.3.

		Updated kmem-based lsof for Linux 2.0.36.

		Updated NetBSD sources for a change in a UVM virtual
		mapping header file.

		Corrected a cache allocation bug in Sun format
		kernel name cache handling.  The bug only shows up
		when the kernel name cache is inaccessible.

4.39		December 29, 1998
		Corrected problems with large device number handling
		for 64 bit Solaris 7.  The problems were reported
		by Steve Bellenot <bellenot@math.fsu.edu>.  Steve
		helped test the fixes.  The fixes were offered as
		two patches to lsof 4.38.

		Improved FreeBSD Configure operations for header
		files that must be obtained from the kernel source
		tree, based on a suggestion from David O'Brien
		<obrien@NUXI.com>.

		For Bela Lubkin <filbo@deepthought.armory.com> made
		optional with +f[cfn] the display of file structure
		address, shared use count, and node structure
		address.  /proc-based Linux doesn't implement this
		feature, because it doesn't read kernel structures
		from kernel memory.  Modified the PTX -X option to
		take advantage of the new file structure display
		option.  Added shared.perl5 to the scripts/
		subdirectory to provide an example of how +f[fn]
		might be used to track shared file descriptors and
		files.

		Added more /dev/kmem-based Linux glibc evasions,
		provided by Jeff Johnson <jbj@redhat.com> and Maciej
		Lesniewski <nimir@kis.p.lodz.pl>.  Jeff helped test
		them on various Linux architectures.

		Tested on AIX 4.3.2; no changes were required.
		Doug Crabill <dgc@purdue.edu> provided a test
		system.

		Fixed -c option to detect missing command name when
		following option begins with `+'.

4.40		January 25, 1999
		Added support for using the CDS compiler for Reliant
		Unix 5.44 and above.  Made Reliant Unix MIPC support
		optional, dependent on the presence of <sys/mipc.h>.

		Based on a report from Michael Schmitz <MSchmitz@lbl.gov>
		that /dev/kmem-based lsof misbehaves on a Linux
		2.0.x m68k kernel without module support, made the
		absence of query_module() or get_kernel_syms()
		Linux kernel support a fatal error.  Updated relevant
		sections of 00FAQ to reflect the change.

		Added the ability to force the Linux Configure
		stanza to use the /proc or /dev/kmem source base
		via a LINUX_BASE environment variable specification.
		This is a cross-configuration assist.

		Added "+D <dir>" and "+d <dir>" options for directory
		searching.  +D searches the entire tree, starting
		at <dir>, including <dir>, its contents, and its
		subdirectory branches; +d searches only <dir> and
		its contents, but not its subdirectory branches.
		Improved lsof's searching of the specified name
		list to compensate for anticipated long lists from
		+d and +D.

		Made an egrep in the Solaris Configure stanza usable
		by the standard and XPG4 egrep's.  Kenneth Stailey
		<kstailey@disclosure.com> pointed out the improvement.

		Fixed bugs in /dev/kmem-based Linux and UnixWare
		Unix domain socket name searching.

		Changed a Linux Alpha #include to be conditional
		on the presence of its named header file, so that
		lsof will compile on Red Hat 5.1 and 5.2 (Linux
		kernel 2.0.35) where the header file is absent.
		The problem was reported by Alexandre Oliva
		<oliva@dcc.unicamp.br>.

		Fixed an AIX 4.3+ bug in procinfo struct space
		allocation, reported by Jeff Stewart <jws@purdue.edu>.
		This was offered as a patch to 4.39.

		Added an lstatsafely() function to offer the same
		isolation for lstat() calls that statsafely() offers
		for stat() calls.  This made DOSTAT_FUNCTION no
		longer necessary, so deleted it.

		With help from Laurent P. Montaron <lpm@sequent.com>
		ported lsof to PTX 4.4.4.  Laurent did a monumental
		job of identifying TCP/IP changes by their TCP
		version, rather than by their PTX (With mix 'n
		match PTX and TCP/IP versions, the PTX version
		often has no bearing on the TCP/IP version.), and
		changed the Configure script and pre-processor
		#if/#else/#endif blocks to match.  He also updated
		Unix domain socket handling for PTX TCP/IP versions
		4.5 and above.

		Updated CLIENT handle acquisition of fill_portmap()
		in print.c to use the more modern RPC function
		clnt_create() in place of clnttcp_create() where
		possible.  PTX 4.4.4 requires clnt_create().

4.41		February 27, 1999
		Added FreeBSD 3.1 and and 4.0 support with help
		from Sheldon Hearn <axl@iafrica.com>, David O'Brien
		<obrien@NUXI.com>, and John Polstra <jdp@polstra.com>.

		Corrected bungled AIX 4.3+ patch that went into
		lsof 4.40.

		Reorganized the Configure script to improve Makefile
		construction.  A specific impetus for this was to
		allow FreeBSD system-wide make flags to be propagated
		to the lsof Makefiles, but other goals were to make
		sure that the DEBUG= make entry can over-ride
		standard CFLAGS values, and to better manage the
		identification of compilers and their versions.
		Two compiler-related values may now be supplied in
		environment variables: 1) the compiler path in
		LSOF_CC; and 2) the compiler version in LSOF_CCV.
		00XCONFIG documents them.

		Added support for Pyramid Reliant Unix bsdsfs,
		msockfs, and sockfs file systems.

		Added an optional LSOF_CINFO string to Configure,
		producing a CINFO string in selected Makefiles,
		producing a #define LSOF_CINFO in selected version.h
		header files.  The purpose of this is to allow
		Configure the option to propagate information to
		the lsof -v output.  It is now used for Linux to
		identify the code base, and for HP-UX 10.30 and
		11.0 and Solaris 7 to identify the kernel bit size.

		Added system information to NEXTSTEP and OPENSTEP
		-v output, from the second line of hostinfo's
		output.

		Fixed a login name buffer overflow problem in the
		processing of -u option values.  This was offered
		as a patch to 4.40.  !!!THIS IS A SERIOUS STACK
		OVERFLOW BUG; A LINUX EXPLOIT EXISTS FOR IT THAT
		OPENS A BASH SHELL WITH LSOF'S AUTHORITY -- E.G,
		SETGID(KMEM) POWER!!!

		Improved the Solaris mount table filter so the
		volume manager's fake mount point, "/vol", is
		ignored and doesn't supplant "/" in NAME column
		path assemblies.  Igor Schein <igor@txc.com> reported
		this bug and provided important help in finding
		it.  This was offered as a patch to 4.40.

		Changed the Linux /dev/kmem-based lock ownership
		test to answer a problem reported by Tom Christiansen
		<tchrist@jhereg.perl.com>.  This was offered as a
		patch to 4.40.

		Installed an HP-UX 11 patch, suggested by Kevin
		Vajk <kvajk@cup.hp.com>, that adjusts a private
		lsof kernel header file, derived via Q4, to correspond
		to an HP-UX patch bundle.

		Made NetBSD 1.3I sockproto structure adjustment.

4.42		March 30, 1999
		Fixed a typo in the HP-UX dfile.c that caused +fF
		and +fN output controls to swap effect.

		Enabled for OpenBSD 2.5 per notice from Kenneth
		Stailey <kstailey@kstailey.tzo.com>

		Made more VM accommodations for FreeBSD 4.0.

		Improved file system search reporting to include
		path name components when they're available, instead
		of mindlessly reporting the file system name in
		the NAME column.  Guy Dallaire <gdallair@geocities.com>
		brought the need for this change to my attention.

		Updated Solaris 2.6 VxFS for Veritas Oracle Database
		Edition 2.0, VxFS version 3.3, and VxVm version
		2.5.4, based on a report from Chris Kordish
		<chris.kordish@East.Sun.COM>.  Chris kindly provided
		a test system.

		Improved HP-UX ipc_s patch detection in Configure,
		response in .../dialects/hpux/hpux11/ipc_s.h, and
		documentation in 00FAQ, Kevin Vajk <kvajk@cup.hp.com>
		helped test.

		Added to Customize the option to suppress HASKERNIDCK
		selection for specified dialects.  Suppressed it
		for /proc-based Linux lsof, and removed its test
		and code from there.  Tin Le <tin@netimages.com>
		alerted me to the need for this update.

		Ported to official Digital UNIX 5.0 release.

		Changed DU lsof to use the knlist(3) function when
		no kernel file has been specified with -k.  This
		change was suggested by Erich Wimmer
		<Erich.Wimmer@digital.com>.

		Updated Configure for latest NetBSD (1.3I?) with
		UVM support the default.

4.43		May 11, 1999
		Corrected a typo in the Solaris gcc discussion in
		00FAQ.  Made changes to the Solaris 2.5[.1] private
		tcp_s structure.  Both changes were done in response
		to reports from Igor Schein <igor@txc.com>, who
		tested the Solaris 2.5 change.

		Made more IPv6 adjustments to lsof for Tru64 UNIX
		(Digital UNIX) 5.0, based on information obtained
		from Compaq by Berkley Shands <berkley@cs.wustl.edu>.

		Corrected HP-UX error message about HP-UX 11 q4 usage.
		Amir Katz <amir@ndsoft.com> reported the correction.

		Fixed a GlibC 2.1 conflict in /proc-based Linux lsof.

		Fixed a man page typo reported by Vlad Harchev
		<hvv@hippo.ru>.

		Changed some Solaris 2.7 references to Solaris 7
		in Configure and 00XPORTING.

		Added a Solaris example to the echo statements that
		are the install rule in the SunOS/Solaris Makefile.

		Added a field to the file structure output --
		FILE-FLAG (file structure open flags, f_flag[s],
		and process file flags, typically u_pofile)) --
		enabled with +f[gG].  Its field output character
		is 'G'.

		Figured out another piece of the HP-UX 11 patched
		ipc_s structure puzzle with the help of Keith Kalet
		<KEITH_KALET@HP-USA-om41.om.hp.com>.

		Fixed a PTX real vnode to real inode interpretation
		bug.

		Added link count to lsof output.  Eric Dumazet
		<dumazet@risgw.ris.fr> requested and helped test
		it.  The new +L option enables and filters it.
		Its field output character is `k'.

		Updated Configure script to recognize NetBSD 1.4.

		Updated AFSConfig to handle default answers to
		questions.

		Incorporated patch from Jonathan Sergent <sergent@io.com>
		that enables /proc-based Linux lsof to run on both
		32 and 64 bit kernels.

		Updated Configure script with a patch from David
		O'Brien <obrien@NUXI.com> that recognizes FreeBSD 3.2.

4.44		June 24, 1999
		Corrected use of nlink member of hsnode for SunOS
		4.1.x High Sierra File System files.  John Dzubera
		<zube@tlaloc.stat.colostate.edu> reported the
		problem and helped test the fix.  Also fixed a
		SunOS segmentation fault bug.  These fixes were
		offered as a patch to 4.43.

		Improved handling of /proc-based Linux UNIX PCB
		address.

		Fixed a NEXTSTEP and OPENSTEP bug that made repeat
		option (-r) processing malfunction.  This fix was
		offered as a patch to 4.43.

		Fixed Configure so it doesn't use -O in the Cflags
		for the bundled HP-UX C compiler.  Jim Ankenbrandt
		<jankenbrandt@penton.com> reported the problem.

		Corrected output ordering of parent PID and process
		group ID when both -R and -g are specified.

		Enhanced the pdev.c and pdvn.c library modules for
		wider use.  These dialect versions use the new
		library modules: DEC OSF/1, Digital UNIX, and Tru64
		UNIX; Pyramid DC/OSx and Reliant UNIX; SCO OSR and
		UnixWare; and Sequent PTX.

		Added basic clone device support to /dev/kmem-based
		HP-UX lsof for HP-UX 10.30 and higher.

		Added raw socket support to /proc-based Linux lsof.

		Changed NODE-ADDR column title to NODE-ID in
		anticipation of using more general identification
		information in the column.

		Ported to UnixWare 7.1, using a test system kindly
		provided by Matt Thurmaier <matt@compclass.com>
		and Don Draper <dond@sco.com>.

		Updated for NetBSD 1.4C VM changes, and a new
		current and root working directory structure.

		Made minor adjustment for latest Tru64 UNIX 5.0
		Beta release.

4.45		July 30, 1999
		Fixed quoting problem in DEC OSF/1, Digital Unix,
		and Tru64 UNIX Makefile's install rule.  The problem
		was reported by Berkley Shands <berkley@cs.wustl.edu>.
		Fixed bug in Tru64 UNIX 4 lsof that caused FDs to
		be skipped.  These fixes were offered in a patch
		to 4.44.

		Fixed a repeat-mode /proc-based Linux lsof bug,
		reported by Sami Farin <sfarin@ratol.fi>.  This
		was offered as a patch to 4.44.

		Picked lint, some reported by Sami Farin.

		Corrected a 00DCACHE documentation error in a sample
		shell script.  The problem was reported by Chad R.
		Larson <chad@larsons.org>.  Changed commented-out
		entries in machine.h files so they require more
		thought and work when the comments are removed,
		based on a remark by Chad.

		Compensated for the practice of Solaris 7 and above
		to record the dev= value in /etc/mnttab in 32 bit
		mode, even on 64 bit systems.  This was offered as
		a patch to 4.44.

		Added a C library test for /proc-based Linux lsof,
		so that the #include files can be adjusted for a
		non-GlibC environment.  The need for this was
		reported by Andrew Hill <andrewh@tirin.openworld.co.uk>.
		This was offered as a patch to 4.44.

		Added support for Auspex LFS 1.8.1 and 1.9.2 to
		SunOS 4.1.4 lsof.  The support was requested by
		Quentin Fennessy <quentin@dvorak.amd.com>, who
		provided information and did testing.

		Enabled IPv6 support code for NetBSD and OpenBSD,
		conditional on Configure script tests.  Wolfgang
		Rupprecht <wolfgang@wsrcc.com> supplied the NetBSD
		code and tested it.  The OpenBSD code I constructed
		has been compiled but not tested.

		Updated the identd Perl 5 script, based on a report
		from Wendy Lin <af5@taiyang.cc.purdue.edu> that
		the space in its response line in front of the user
		name violates RFC 1413.

		Added IPv6 support to /proc-based Linux lsof.
		Jonathan Sergent <sergent@ETLA.NET> and Andrew
		Thomas Sydelko <sydelko@ecn.purdue.edu> kindly
		provided a test system.

		Updated man page description of AIX multiplexed
		files to indicate that they might be /dev/ptc or
		/dev/pts, depending on the AIX version.  The
		correction was suggested by Onno van der Linden
		<onno@simplex.nl>.

		Sylvain Robitaille <syl@alcor.concordia.ca> reports
		lsof passes his Y2K tests.

4.46		October 23, 1999
		Corrected /proc-based Linux lsof to detect that an
		IPv6 address is a mapped IPv4 address.  The problem
		was reported and analyzed by Arkadiusz Miskiewicz
		<misiek@misiek.eu.org>, who also tested the fix.

		Added a libc5 library /dev/kmem-based Linux lsof
		circumvention, supplied by Jason Lingohr
		<lingman@lucid.net.au>.

		Corrected a bug in -t (terse) AIX output, reported
		by Wendy Lin <af5@taiyang.cc.purdue.edu>.  I
		introduced the bug at revision 4.43 when adding
		FILE_FLAG reporting.  This was offered as a patch
		to 4.45.

		Added a work-around for a problem in the OpenBSD
		2.3 <sys/pipe.h> header file.  Volker Borchert
		<bt@teknon.de> provided and tested it.

		Improved description of cross-building lsof for a
		64 bit Solaris 7 system on a 32 bit system with
		suggestions from Phillip Edwards
		<Philip.Edwards@sn.wpafb.af.mil>.

		Fixed a gawk POSIX-mode pattern error in the Linux
		/dev/kmem-based Mksrc script, based on a tip from
		Ambrose C. Li <acli@mingpaoxpress.com>.

		Fixed a bug in the Tru64 UNIX IPv6 handling, courtesy
		of a report from Casper Dik <casper@holland.sun.com>.

		Enabled support for OpenBSD 2.6.

		Enabled support for BSDI BSD/OS 4.1, based on a
		report from Jeffrey C Honig <jch@bsdi.com> that
		only a Configure script change is necessary.

		Enabled Configure script to use gcc for building
		lsof for a 64 bit Solaris 7 and 8 kernels, if the
		gcc version is 2.95 or above.

		Improved -i option handling for systems with IPv6
		support so that it will search for a host name in
		both IPv4 and IPv6 families, when that is possible.
		As a companion modification, changed -V processing
		to report a single error when a multiple host name
		match is requested.  Casper Dik <casper@holland.Sun.COM>
		helped test.

		Fixed a DEC OSF/1, Digital UNIX, Tru64 UNIX repeat
		mode bug, reported by Mayer Ilovitz <mayer@cooper.edu>.
		Mayer helped test the fix.  The fix was offered as a
		patch to 4.45.

		Changed Solaris socket file recognition scheme, so it
		is (nearly) the same through Solaris 8, where the
		previous clone device scheme no longer works.

		With significant assistance from Casper Dik, added
		support for Solaris 8 Beta and Beta refresh.  The
		IPv6 support in Solaris 8 is still in some flux,
		so there are temporary compensations for the
		differences between Beta IPv6 support and Beta
		refresh IPv6 support.  Casper and I hope those
		differences disappear by FCS.

		Improved the delivery of information on Solaris
		2.5.1, 2.6, 7, and 8 door files.

		Fixed a repeat mode bug that surfaces when /etc/passwd
		changes between cycles.  The bug report and diagnostic
		help were supplied by Igor Schein <igor@txc.com>.
		The fix was offered as a patch to 4.45.

		Added support for INRIA IPv6 to NetBSD.  Jean-Luc
		Richier <Jean-Luc.Richier@imag.fr> provided patches
		and a test system on which to verify them.

		Added support for AIX 4.3.3.  Jeff W. Stewart
		<jws@anaconda.cc.purdue.edu> provided a test system.

		Made adjustments for FreeBSD 4.0-current.

		Improved reporting of information for AIX sockets that
		lack protocol control blocks.

4.47		November 29, 1999
		Based on a query from Jean-Pierre Radley <jpr@jpr.com>,
		changed the lsof top-level Makefile to propagate
		CFGF to the library Makefile.  (DEBUG was already
		being propagated.)  Added osrgcc and scogcc Configure
		abbreviations (to use gcc) for Jean-Pierre.

		In response to a query from Igor Schein <igor@txc.com>,
		improved the Configure script test for Solaris 7
		and 8 that decides if the compiler can produce 64
		bit executables.

		Made an ugly hack, based on making a private rnode
		structure definition from q4 output, to compensate
		for HP-UX 10.20 and lower recent NFS3 patches.  HP
		didn't supply an updated <nfs/rnode.h> with the
		patches.  The problem was reported by Will Partain
		<partain@mekb2.sps.mot.com>.  Elias Halldor Agustsson
		<elias@hi.is> helped identify the patches as
		PHNE_18173, PHNE_19426, PHNE_19937, and PHNE_20091,
		and provided a test system.

		Switched BSDI test system from 2.1 and 3.1 to 4.0.1,
		courtesy of Terry Kennedy <terry@tmk.com>.

		Added some more dev_t hacks for Alpha FreeBSD 4.0.

		Added support for IPv6 on BSD 4.x.  The support hasn't
		yet been tested, just compiled.

		Added support for the mnt file system (mntfs or
		/etc/mnttab) on Solaris 8.  Tested on Solaris 8
		BETA-Refresh.

		Made selection of optional fields (e.g., PPID with
		-FR) in a field output specification select the
		optional field, too, so that the option selector
		for the field (e.g., -R) isn't also required.  This
		change was made in response to an inquiry from John
		DuBois <spcecdt@armory.com>.  This may require some
		revision to scripts that parse all field output;
		two scripts in the lsof distribution's scripts/
		subdirectory had to be updated.

		Corrected handling of Linux IPv4 addresses mapped
		in IPv6 addresses.

		Tested under OpenBSD 2.6.

4.48		January 14, 2000
		Modified -i argument processing of colon-separated
		IPv6 addresses to recognize an IPv4 address mapped
		in an IPv6 address and handle it as an IPv4 address.
		This was offered as a patch to 4.47.

		Added a defined symbol (NOWARNBLKDEV) to control
		(inhibit) the issuance of a warning when no block
		devices are found.  This was done anticipating its
		need in FreeBSD 4.x, but that dialect version no
		longer has any block devices, so HASBLKDEV was
		disabled for it instead.  NOWARNBLKDEV was left in
		place for possible use in the future.

		Enabled KAME IPv6 Configure support for FreeBSD
		when <netinet6/in6.h> is found.

		Disabled use of gcc to compile lsof for 64 bit
		HP-UX 11.

		Updated Configure to recognized FreeBSD 3.4.

		Based on suggestions from Bernt Christandl
		<beb@MPA-Garching.MPG.DE> improved AFS configuration
		for AIX and Solaris, and updated AIX AFS 3.5 support.
		Johannes Tax <tax@bluedog.oit.unc.edu>, Hung T.
		Pham <hung_pham@unc.edu>, and Curt Freeland
		<curt@grumpy.cse.nd.edu> provided test systems.

		Updated lsof's private rnode definition for AIX
		4.3.3, since IBM still doesn't ship the
		<oncplus/nfs/rnode.h> header file and the rnode
		structure definition in <nfs/rnode.h> doesn't match
		what the kernel uses.  This was offered as a patch
		to 4.47.

		Weakened the test in the Linux /proc-based lsof of
		the field count of data lines in /proc/net/{tcp,udp}.
		It appears that recent 2.3.x Linux kernels have
		added untitled fields to these files.  The bug
		report came from Gabor Liptak <gaborliptak@usa.net>.

		Adjusted for a FreeBSD 4.0 change in the definition
		of [_]KERNEL.  David O'Brien <obrien@NUXI.com> reported
		the problem and provided a test system.

		Removed the HASPPID bracket from Fppid (the -R
		option state variable) so that the field select
		table will compile even when HASPPID is not defined.
		This problem was introduced at revision 4.47 with
		code that causes some field output characters to
		set option states.  The problem was reported by
		David Bacon <bacon@birch.eecs.lehigh.edu>.

4.49		April 3, 2000
		Made clearer in man page that "Lxx" FDs are AIX
		loader table references.  Also updated the 00FAQ
		discussion of the Stale Segment ID bug to include
		AIX 4.3.x.

		Modified support for NetBSD 1.4Q to include the
		<sys/buf.h> header file to cope with an MFS change.

		Added support for OpenBSD UVM virtual memory.

		Added support for AIX systems with > 2GB of memory.
		Chris Sylvain <csylvain@itg.ummc.umaryland.edu>
		reported the problem and provided the solution.
		Chris also supplied some minor code cleanup.  This
		was offered as a patch to 4.48.

		Based on new information from Igor Schein <igor@txc.com>
		made additional compensation in Configure script
		for 64 bit Solaris 7 and 8 gcc.

		Added some 00FAQ info on the effect ordering of
		the +fg and -FG options has on output format.

		Improved NetBSD IPv6 configuration, based on a
		suggestion from Thomas Klausner
		<wiz@danbala.ifoer.tuwien.ac.at>.  Added code to
		convert IPv4-mapped-in-IPv6 addresses to IPv4
		addresses.

		Updated the information in 00FAQ and the HP-UX 11
		binary directory README files on the HP-UX 11 ipis_s
		patch with new information supplied by Eric McWhorter
		<emcwhorter@xsis.xerox.com>.

		Added documentation on changes to HASFSTYPE and
		HASNCACHE, and the new HASPRIVPRIPP.

		Adjusted Configure for FreeBSD 5.0.  Made additional,
		necessary changes to Configure and the BSDI sources
		to eliminate load errors.

		Added KAME IPv6 support to FreeBSD at the request
		of Ollivier Robert <roberto@eurocontrol.fr>, who
		provided a test system.

		Corrected the script that generates the CHECKSUMS
		files for binaries to correctly name the detached
		PGP certificate.  The documentation bug was reported
		by Michael Hennecke <hennecke@rz.uni-karlsruhe.de>.

4.50		June 29, 2000
		Added a NetBSD alpha test host, courtesy of Ray
		Phillips <r.phillips@mailbox.uq.edu.au>.  An lsof
		4.49 binary, built on Ray's 1.4.1 system was made
		available prior to the 3.50 release.

		Upgraded the system map file tests in /dev/kmem-based
		Linux lsof, making the use of DEBIAN_LINUX_LSOF
		unnecessary.  Tested the changes on a system made
		available by Vincent Kujala <kujala@geog.ubc.ca>
		and Jim Mintha <jim@ic.uva.nl>.

		Forced AIX to use the large-file-enabled versions
		of lstat (lstat64) and stat (stat64) if <sys/stat.h>
		contains stat64.  This should allow lsof to stat()
		AIX files > 2GB even when the builder has not
		defined the "large file enabled programming
		environment."  Configure tests <sys/stat.h> and
		puts -DHASSTAT64 in the Makefile's CFLAGS to make
		this happen.  Fernando A.B. Whitaker
		<whitaker@cenapad.unicamp.br> reported the problem.
		This was offered as a patch to 4.48.

		Enabled Configure script to handle OpenBSD 2.7.
		Angelos D. Keromytis <angelos@dsl.cis.upenn.edu>
		reported the availability of OpenBSD 2.7 and supplied
		the Configure script patch.

		Improved handling of DOOR and fattach()'d files in
		Solaris.

		Changed message about missing kernel symbol file
		from "not yet determined" to "none found".

		Updated FreeBSD, NetBSD, NEXTSTEP, OpenBSD, and
		OPENSTEP support to report "no PCB" and the values
		of the SO_CANTSENDMORE and SO_CANTRCVMORE state
		flags when a socket structure has no inpcb pointer.
		This modification was made to AIX lsof at revision
		4.46.  Added an entry to 00FAQ about sockets that
		have no inpcb pointer.

		Upgraded support for FreeBSD 5.0-CURRENT.  Ben
		Smithurst <ben@scientia.demon.co.uk> supplied
		patches and did testing.  David O'Brien <obrien@NUXI.com>
		supplied a test system.  The update included dropping
		the Fctty part of file descriptor file system
		support, conditional on a Configure script test.
		I propagated those changes to BSDI, NetBSD, and
		OpenBSD in anticipation of their having the
		modification in the future.  David also arranged
		with Michael Haro <mharo@area51.fremont.ca.us> for
		a FreeBSD 3.4 test system.

		In response to an lsof 3.72 bug report from Jim Mewes
		<jim@corp.phone.com>, added more kernel address
		filtering to the lsof function, kread(), that reads
		Solaris kernel data.

		In response to a report from Marc Duponcheel
		<marc@offline.be>, added tests to the /proc-based
		Linux lsof to ignore file systems of types "autofs"
		and "pipfs".

		Based on a report and information supplied by Casper
		Dik <casper@holland.Sun.COM>, updated the ncache_load()
		function in lib/rnch.c with new code that deals
		with a post Solaris 8 change in kernel name cache
		(DNLC) handling.  Casper tested the update, which
		should be invisible to Solaris versions without
		the new DNLC code.

		Added support for Solaris VxFS QIO files, based on
		a report from Kieran Broadfoot <kieran.broadfoot@gs.com>.
		Kieran help test the support.

		Added support for PTX 4.4.6 and 4.5[.1] with help
		from the usual cast of good people at Sequent.

		Added support for 64 bit file sizes and offsets on
		BSDI, FreeBSD, NetBSD, and OpenBSD, based on a
		report from Dan Nelson <dnelson@emsphone.com>.
		Dan supplied a patch and did FreeBSD testing.

		Added Configure script recognition of NetBSD 1.5,
		based on a report from Andrew Brown <atatat@atatdot.net>.
		Thomas Klausner <wiz@danbala.ifoer.tuwien.ac.at> updated
		the NetBSD port package to use a pre-release of this
		addition.

		At the last minute saw a notice via deja.com's
		UseNet search service that FreeBSD 3.5 had been
		released and lsof didn't grok it.  Added recognition
		of 3.5 to lsof's Configure script, but didn't have
		the opportunity to test lsof on 3.5.

4.51		August 21, 2000
		Added Configure script support for the upcoming
		Solaris 9 release based on suggestions from Casper
		Dik <Casper.Dik@holland.sun.com>.

		Changed sample Perl scripts to assume that
		/usr/local/bin/perl is Perl 5 and Perl 4 may be
		found in /usr/local/bin/perl4.

		Updated Configure to recognize FreeBSD 4.1 and made
		a FreeBSD pre-release distribution available.

		Bela Lubkin <belal@sco.COM> tested lsof on the
		upcoming SCO OSR 5.0.6 release and reports that
		lsof appears to work properly.

		Updated the AIX compiler test in Configure to
		recognize its version 5.

		Updated AIX 4.3.3 support with automatic recognition
		of the proper rnode structure, based on machine
		bit width.  Also added code to detect when processing
		the -X option that lsof has been compiled with the
		"other" AIX 4.3.3 user structure and to apply
		compensations.  When a compensation method works,
		it's applied during subsequent -X processing; when
		none works, further -X processing is disabled.

		Added Tru64 UNIX 5.1 support.  Updated Tru64 UNIX
		library text file support to recognize new kernel
		support for AdvFS library files.  Berkley Shands
		<berkley@cs.wustl.edu> and Klaus Saggerer USG
		[saggerer@zk3.dec.com> helped put me in contact
		with Chang Song <song@zk3.dec.com>, the developer
		of 5.1's new kernel name cache and he helped me
		develop new code in lsof to access it.

		Corrected reporting of PTX fattach()'d address.

		Changed Configure and dlsof.h for NetBSD and OpenBSD
		to use /usr/include/uvm header files when available.
		Andrew Brown <atatat@atatdot.net>, Thomas Klausner
		<wiz@danbala.ifoer.tuwien.ac.at>, and Wolfgang
		Rupprecht <wolfgang@wsrcc.com> pointed out the need
		to do this for NetBSD.  Andrew provided access to
		a NetBSD 1.5 system for verifying the changes.

		Installed snprintf() support, including a private
		version in the lsof library for those UNIX dialects
		without the function.  Changed all sources to use
		it instead of sprintf() and strcpy().

		Fixed a memory leak in the readvfs() functions of
		BSDI, DEC/OSF1, Digital UNIX, FreeBSD, NetBSD,
		OpenBSD, and Tru64 UNIX.

		Tested on Linux 2.4.

		Modified the Pyramid MkKernOpts script to compensate
		for `uname -s` configuration alternatives.  Robert
		Dahlem <Robert.Dahlem@ffm2.siemens.de> supplied
		the modification.

		Obtained access to an FCS Solaris 8 64 bit system
		and built lsof on it, using Sun Workshop C 5.0 and
		gcc 2.96 20000814 (experimental).  Both compilers
		produce a working lsof.


4.52		November 8, 2000
		Completed work on an HP-UX 11.11 port that uses a
		pstat(2) interface provided by HP.  To distinguish
		it from its predecessors for HP-UX, this lsof
		version is called PSTAT-based and the predecessor
		versions are now called /dev/kmem-based.  I am
		indebted to the far-sightedness and support of
		these good people at HP for making PSTAT-based lsof
		possible: Carl Davidson, Louis Huemiller, Rich
		Rauenzahn, and Sailu Yallapragada.  The PSTAT-based
		sources are in lsof_4.52/dialects/hpux/pstat, the
		/dev/kmem-based ones in lsof_4.52/dialects/hpux/kmem.

		Ported to IBM Monterey for Merced|Itanium, aka AIX
		5L.  It configures via the Configure script's "aix"
		abbreviation and has been tested on AIX 5L Beta 3.
		Jay Beck, Steve Dibbell, Loc Le, Nasser Momtaheni,
		and Malcom Zung of IBM provided generous support.
		Since AIX 5L is still in Beta testing, this port
		can't be considered complete.

		Added Configure support for OpenBSD 2.8.  David
		Mazieres <dm@cs.nyu.edu> provided a test system.

		Based on a report from Marc Christensen
		<marc@mecworks.com> added sockfs to the mount scan
		exemption list for /proc-based Linux lsof.

		Added large file, CDFS, and DOSFS for UnixWare 7.x.
		Added UnixWare device memory mapping support.  All
		UnixWare changes were supplied by Eric Dumazet
		<edumazet@cosmosbay.com>  Eric also supplied some
		miscellaneous bug fixes.

		Deferred name cache loading until printname() needs
		to use the name cache.

		Terminated Pyramid, SunOS 4.1.x, and Ultrix support,
		because test systems are no longer available.
		Final Pyramid and Ultrix source code distributions
		for lsof revision 4.51 may be found on lsof.itap.purdue.edu
		in pub/tools/unix/lsof/OLD/src.  The no longer
		supported SunOS 4.1.x source code is still distributed
		with the Solaris source code.

		Added code to set Solaris node address to real vnode
		address, when applicable.

		John Speno <speno@lopan.isc-net.upenn.edu> provided
		information that enabled me to update the Tru64
		AdvFS (MSFS) node definition for AdvFS version 5.

		Added Tru64 5.x CFS support with help from Kris
		Chandrasekhar <Kris.Chandrasekhar@compaq.com>,
		Diane Lebel <lebel@zk3.dec.com>, and John Speno.
		The support only provides information about cached
		file attributes.

		Installed a Configure patch for HP-UX 11 supplied by
		Kenneth Stailey <kstailey@disclosure.com> that adds
		another command to q4 input.

		Tested on FreeBSD 4.2.

		Will Day <willday@rom.oit.gatech.edu> and Frank
		Winkler <frank.winkler@germany.sun.com> graciously
		supplied Solaris 8 binaries.

		Added Solaris 9 text file support, supplied by
		Casper Dik <Casper.Dik@holland.sun.com>.

4.53		December 6, 2000
		Added the AIX 5L j2_lock.h to the distribution with
		a Configure script step to use it when it's missing
		from /usr/include/j2.

		Removed SunOS 4.1.x support.

		Removed Linux 2.0.x /dev/kmem support.

		Fixed VBLK and VCHR special device file reporting
		to handle /dev information more accurately.

		Added a Apple Darwin / Mac OS X 1.2 port, provided
		by Allan Nathanson <ajn@apple.com>.  Allan also
		arranged for a test system so I can maintain this
		port.  An additional test system was provided by
		Dale Talcott.

		Dropped claims of support for all UnixWare versions
		except 7.1.0, since that is the only version on
		which I can test lsof.  Even though lsof 4.53 is
		deprecated for UnixWare 2.1.3, installed a patch
		for it with testing done by A. Channing Clark
		<clark.channing@heb.com>.

		Dropped claims of support for all SCO OpenServer
		versions except 5.0.5, since that is the only
		version on which I can test lsof.

4.54		January 19, 2001
		Added compensation for a change that made the
		FreeBSD mount structure invisible.  I can only test
		back to 3.2 and the compensation works there, so
		it's been #ifdef'd for 3.2 and above.  David O'Brien
		<obrien@FreeBSD.org> provided the necessary clue.

		Based on a report from Valdis Kletnieks
		<Valdis.Kletnieks@vt.edu>, changed all IPv6 support
		to report a TYPE of IPv6 for sockets with IPv4
		addresses mapped in IPv6 addresses.  The previous
		lsof behavior was to report their TYPE as IPv4.

		Restored the Linux GlibC test to Configure, removed
		at revision 4.53, based on a report from John Dzubera
		<zube@cs.colostate.edu>, that RedHat Linux 6.0 still
		needs the test.

		Made setting of link count for Solaris more selective.

		Limited Readlink() recursion to MAXSYMLINKS.  The bug
		was reported by Jan Dvorak <johnydog@go.cz>.

		Dropped the *claim* that lsof runs on Solaris 2.5.1.
		It may well do so, but I no longer have access to a
		test system.

		Fixed an #endif comment typo, reported by Igor Schein.

		Fixed a typo in a cast for a Tru64 UNIX 5.1 function
		and updated Configure for Tru64 UNIX 5.0 and 5.1 with
		information from Jesse Perry <jesse.perry@compaq.com>.

		Corrected non-fatal typos in the AdvFS support in
		dnode.c for Tru64 UNIX.

		Added msdos file system support for NetBSD and OpenBSD.
		Andrew Brown <atatat@atatdot.net> requested and helped
		test it.

4.55		February 15, 2001
		Based on a report from Bernd Eckenfels <ecki@lina.inka.de>
		added support in lsof for files in /proc/<PID>/maps
		that have been deleted.

		Changed PGRP output title to PGID, conforming to
		the most common current abbreviation for Process
		Group ID (PGID).  While some systems continue to
		use *pgrp for internal kernel variable names, most
		systems that support the display of PGID via ps(1)
		now title it PGID.  The lsof -g and -Fg options
		operations are unchanged in function; only titles
		and descriptions have changed.  Also changed internal
		variable names from *PGRP and *pgrp to *PGID and
		*pgid where possible.

		Dropped the *claim* that lsof runs on HP-UX 9.x.
		It may well do so, but I no longer have access to
		a test system.

		In response to a suggestion from Jeff Howie
		<jeff.howie@federated.ca> added support for command
		name selection by regular expression.  A new form
		of the -c option value is use to identify and
		specify a regular expression.

		Restore the *claim* that lsof works on UnixWare
		7.0, since I re-acquired a test system.

4.56		May 3, 2001
		Corrected some problems Amir Katz <Amir_Katz@bmc.com>
		found with Insure++, one in lib/dvch.c, the rest
		in Solaris sources.  Amir's report also helped me
		find an error in an snpf() call that caused (the
		unsupported) Solaris 2.5.1 lsof to crash.  Wally
		Winzer, Jr. <wally.winzer@ChampUSA.COM> helped test.

		Added support for UnixWare 7.1.1 and above in-kernel
		UNIX sockets.  John Hughes <john@Calva.COM> kindly
		provided code and access to a test system.  John
		also provided a test system and advice for adding
		UnixWare 7.1.1 NonStop Cluster and CFS support.
		More help with that effort came from Kurt Gollhardt
		(SCO), Barbara Howe (SCO), Bela Lubkin (SCO), and
		Dewan Rashid <Dewan.Rashid@ir.com>.

		Archived a set of compilation hints (patches) from
		Bill Melvin <Bill.Melvin@esc.edu> that make it
		possible to compile the old, unsupported lsof 3.08
		sources on UnixWare 1.x without NFS or CDFS support.

		Installed support supplied by Allan Nathanson
		<ajn@apple.com> for the Darwin "Gold Master" release,
		Mac OS X 10.0 (aka Darwin 1.3 in its public source
		version).  Added Allan's CVS repository suggestions
		to the script that gets additional header files
		from an open source repository.

		Tested an HP-UX 11.11 kernel patch from Sailu
		Yallapragada that enables reporting of TCP/IP
		information for telnetd processes that use the
		telnet multiplexor.  I don't yet know the kernel
		patch ID.

		Made the Solaris inclusion of <inet/mi.h> conditional
		on the Solaris version.  (It's apparently not needed
		at 2.6 and above.)  Bill Watson <bill.watson@uk.sun.com>
		brought this to my attention.

		Added alternate Linux 2.4.x lock extent test, supplied
		by Jim Mintha <jim@ic.uva.nl>.

		Rearranged the lines and pre-processor tests in
		regex.h, lib/regex.c, and lib/snpf.c so that unifdef
		can be used to eliminate copyright and GPL statements
		when the files aren't being used for a particular
		dialect.  (USE_LIB_* definitions in a dialect's
		machine.h header file determine if one or more of
		those three files are to be used.)

		Added preliminary support for Solaris 8 with VxFS
		3.4.  This support will be refined as I get
		information from Veritas about how they will
		distribute the kernel header files lsof needs.
		Those header files were omitted from the standard
		VxFS 3.4 distribution.  Technical assistance and
		testing were provided by Calle Dybedahl <cdy@algonet.se>,
		Gary Millen <gary.millen@veritas.com>, Rainer Orth
		<ro@TechFak.Uni-Bielefeld.DE>, Peter C. Vernam
		<pvernam@draper.com>, and Donna Yobs
		<Donna.Yobs@veritas.com>

		Tested on FreeBSD 4.3-STABLE.

		Dropped the *claim* that lsof works on UNIX dialects
		where I no longer have test systems: BSDI 2.1,
		3.[01] and 4.0; DEC OSF/1, Digital UNIX and True
		64 UNIX 2.0 and 3.2; FreeBSD 2.1.[67], 2.2[.x],
		3.[012345] and 4.[01]; HP-UX 10.20; NetBSD 1.[234];
		SCO OpenServer 5.0.5; and SCO UnixWare 7.0

		Tested on Solaris 9 BETA, s81_36.

4.57		July 19, 2001
		Help (-h) and version (-v) output now have URLs
		for the newly created and timeliest lsof FAQ
		(00FAQ in the lsof distribution) at:

		  ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/FAQ

		and the man page for the current lsof distribution
		at:

		  ftp://lsof.itap.purdue.edu/pub/tools/unix/lsof/lsof_man

		Based on a report from Steve Laubscher
		<slaubs@woodward.com>, modified dlsof.h for PTX
		4.6[.1] to avoid a temporary dnlc_t definition
		needed at PTX 4.5.1.

		Corrected test for old Linux kernels in Configure.
		Henri Karrenbeld <ishtar@cal044202.student.utwente.nl>
		brought the error to my attention.  Limited Linux
		claims to 2.1.72 and above in the documentation.

		Improved HP-UX 11 Configure stanza and stream socket
		handling.

		Constructed a work-around for the HP-UX 11 optional
		OnlineJFS package.  The work-around sadly requires
		lsof to have a private version of the vx_inode
		structure, since the OnlineJFS package doesn't
		update <sys/fs/vx_inode.h>.  Troyan Krastev
		<Troyan.Krastev@ricoh-usa.com> brought the bug to
		my attention and Michael Bracewell
		<michael@ra.TSS.PeachNet.EDU> provided a test system
		where I developed the work-around.

		Added locale support to lsof's isprint() test,
		based on a suggestion from Dan Mercer <damercer@mmm.com>.
		Lsof will use setlocale(), when that function and
		its supporting <locale.h> header file are available.

		Added OpenBSD 2.9 support.

		Based on a report from Aaron Rhodes <arhodes@psionic.com>
		and with testing help from Aaron, made the lsof
		4.56 revision compile and work on OpenBSD 2.6.
		While that OpenBSD version is no longer supported,
		Aaron's report exposed a Configure script bug
		affecting OpenBSD versions lsof does support.

		Updated for FreeBSD 5.0-CURRENT.  Szilveszter Adam
		<sziszi@petra.hos.u-szeged.hu> help test.  The lsof
		FreeBSD ports packager, David O'Brien <obrien@FreeBSD.org>,
		assisted.

		Tested on AIX 5.1.  Loc Le and Nasser Momtaheni of
		IBM provided test systems.

4.58		September 13, 2001
		Added options to safestrprt() and safestrprtn() to
		surround the string with '"' and to suppress the
		printing of an ending '\n'.  Use of these functions
		in device cache file error message reporting answers
		a suggestion for better error reporting from John
		Jackson <jrj@purdue.edu>.

		Fixed a Solaris 2.6 and above problem related to
		searching for "large" (O_LARGEFILE) files by name;
		lsof was using the wrong version of [l]stat(2).
		The bug was reported by Daniel Trinkle
		<trinkle@cs.purdue.edu>.

		Added AIX 4.1.4 and above XTI socket support.

		Added OSR Xenix Shared Data and Semaphore file type
		support with modifications supplied by Bela Lubkin.

		Updated OPENSTEP support with modifications from Carl
		E. Lindberg <lindberg@clindberg.org>.  The changes
		enable the correct reporting of executable and
		library open files ("txt" type).

		Limited claims of OpenServer support to the versions
		where I currently test, 5.0.4 and 5.0.6.  (Lsof
		probably works on 5.0.5.)

		Enabled processing of -C option for PSTAT-based HP-UX
		lsof.

		Enabled and tested on FreeBSD 4.4.

		Corrected a file system test example in 00QUICKSTART,
		based on a report from Jun Biao WANG <wangjunb@cn.ibm.com>.

		Made available for re-distribution a user-contributed
		port of lsof 4.51 to Reliant UNIX 5.45.  Thomas
		Mauterer <Thomas.Mauterer@philosys.de> contributed
		the port.

4.59		October 20, 2001
		With the closing of the Sequent Synergy Links Lab
		by IBM, terminated lsof support for PTX.  The last
		tested PTX lsof revision, 4.58, is available on
		lsof.itap.purdue.edu in .../lsof/OLD/src.

		Adjusted for FreeBSD 5.0-CURRENT NFS header file
		changes, based on a report from Jos Backus
		<josb@cncdsl.com>.

		Corrected a bug in the way Linux lsof identifies
		the owner of a process.  Lionel Cons <lionel.cons@cern.ch>
		reported the problem and tested the fix.  Added
		code to avoid stat(2) calls on regular Linux files
		whenever possible.  Lionel reported the need to do
		this (AFS files) and tested the new code.

		Added new output field for raw device number in
		hex.  The field is identified with 'r'.  This field
		is NOT selected when -F or -F0 is specified so that
		its appearance won't disturb existing scripts that
		process field output.

		Added support for OpenUNIX 8.  A test system was
		provided by Larry Rosenman <ler@lerctr.org>.
		Matthew Thurmaier <matt@compclass.com> and many
		people from Caldera provided technical assistance.

		Added an additional UVM test to the NetBSD Configure
		stanza.  Andrew Brown <atatat@atatdot.net> supplied
		the test; it recognizes NetBSD 1.5Y UVM changes to
		the vnode structure recently committed by Chuck
		Silvers.

		Applied Configure and get-xnu-headers.sh script
		changes suppled by Allan Nathanson <ajn@apple.com>
		for Darwin 1.4.

		Added for Bela Lubkin <belal@mammoth.ca.caldera.com>
		OSR-specific environment variables to supply values
		to the Configure script.  The variables are described
		in 00XCONFIG.

		Added an IP version selector to the -i option
		parameters.

4.60		November 9, 2001
		Added special handling to and corrected bugs in
		the matching of IPv4 in IPv6 addresses to -i6:<...>
		selectors.

		Made 00FAQ corrections and updates, based on
		discussions with Igor Schein <igor@txc.com>.

		Modified Configure script to detect a 64 bit capable
		gcc compiler and permit it to be used to build 64
		bit (PA-RISC 2) lsof for HP-UX 11.00.  Tested with
		HP's gcc package, which Rich Rauenzahn of HP kindly
		installed on a test system at HP.  Stefan Marquardt
		<stefan.marquardt@hagebau.de> helped test.

		Made lsof's method of killing its child process
		more robust, based on a suggestion from Bela Lubkin
		<belal@caldera.com>.

		Modified all dialect Makefile segments to accept
		select -v #define's from the environment -- a
		builder's comment, host, logname, system information
		and user name.  This was done for Bela Lubkin, so
		he can "tune" the -v output when he packages lsof
		in the upcoming Caldera OSR 5.0.7 release.

		Changed Perl scripts in scripts/ to put the lsof
		path consistently in $LSOF.  Also added a fix from
		Bela Lubkin to scripts/big_brother.perl5 that allows
		it to tolerate SCO OSR "ago" clauses in open UDP
		file information.  Strengthened emphasis in
		scripts/00README that the scripts are examples that
		shouldn't be expected to run on all UNIX dialects
		without modification.

		At Bela Lubkin's suggestion changed the device
		cache file format examples in 00DCACHE and 00FAQ
		to avoid "%U%".  That's an SCCS escape sequence.

		Added support for OpenBSD 3.0.

		Added +DAportable to CFLAGS for 32 bit HP-UX 11.
		Amir Katz <Amir_Katz@bmc.com> suggested the addition.

4.61		January 22, 2002
		Updated field output example Perl scripts in the
		scripts/ subdirectory to discover the lsof path,
		starting at .. and proceeding through the PATH
		environment variable's directories.

		Added minor OSR Configure script fixes, provided
		by Bela Lubkin <belal@caldera.com>.

		In response to a report from Joshua Wright
		<Joshua.Wright@jwu.edu> modified NetBSD and OpenBSD
		Configure stanzas and sources so that lsof can be
		built when there is no system source tree (e.g.,
		/usr/src/sys).

		In response to a report from Peter Valchev
		<pvalchev@openbsd.org> improved the UVM test in
		the OpenBSD Configure stanza.

		Updated Configure script to recognize FreeBSD 4.5.
		Updated for FreeBSD 5.0 procfs and pseudofs changes.

		Updated HP-UX stanza to see if the compiler named
		in the LSOF_CC environment variable is the bundled
		compiler.  If it is, "-O" is omitted from the
		compiler flags.

		Updated Digital UNIX 4.x and Tru64 UNIX error message
		related to kernel name list failures.  Added an FAQ
		section about how a kloadsrv daemon failure can cause
		knlist(3) to fail.  The condition was reported by
		Douglas B. Jones <douglas@gpc.peachnet.edu>

		Based on a report from Mark W. Eichin <eichin@thok.org>
		made Linux lsof capable of handling and reporting
		file sizes greater than 32 bits.

		Tested on Solaris 9 BETA-Refresh.

		Corrected a bug in the matching of IPv4 addresses,
		mapped in IPv6 addresses, to an IPv4 parameter to
		an -i option.

		Ported to 64 bit Power AIX 5.1 kernel with advice
		from David Clissold <cliss@austin.ibm.com> and Marc
		Stephenson <marc@austin.ibm.com>, and on a test
		system provided by Loc Le <lple@us.ibm.com>.

4.62		March 7, 2002
		Updated 00README to reflect the usefulness of gcc
		for building AIX lsof.  Documented a report from
		Brian L. Gentry <BGentry@nationsrent.com> of success
		on AIX 4.3.3.  I documented my success on 32 bit
		Power AIX 5.1 and my lack of success on ia64 AIX
		5.1 and 64 bit Power AIX 5.1.

		Improved UnixWare >=7.1.1 reporting of UNIX socket
		NAME field information for NonStop Cluster systems
		with a patch provided by John Hughes <john@Calva.COM>.
		Offered John's improvement as a patch to lsof 4.61.

		Corrected bugs in handling of open files on block
		devices by OSR lsof.  The bugs were reported by
		Bela Lubkin <filbo@deepthought.armory.com>.

		Fixed bug in writing >32 bit device numbers for
		block devices to the device cache file.

		Added support for reporting block special nodes
		not in /dev (or /devices).  That required "like
		device special" be changed to "like block special"
		and "like character special".  (00FAQ was updated.)

		Based on a report from Peter Valchev <pvalchev@openbsd.org>
		improved the definition of the source for NetBSD
		and OpenBSD kernel symbols (the nlist() source
		file).  NetBSD now defaults to getbootfile(3) if
		it is available, /netbsd otherwise.  OpenBSD now
		defaults to /dev/ksyms if it is available, /bsd
		otherwise.

		Made possible compilation under BSD/OS (BSDI) 5.0
		with changes to Configure, dialects/bsdi/dlsof,
		dialects/bsdi/dproc.c and lib/rnmh.c.  The changes
		were suggested by Steven Hinkle <hinkle@bsdi.com>.
		Note that these changes do not substantiate a claim
		that lsof works on BSDI 5.0, because I haven't
		tested it there.

		Updated OpenUNIX private <sys/fs/memfs_mnode.h>,
		based on a report from Larry Rosenman <ler@lerctr.org>
		that it had been updated by Caldera patch OU800PK3.
		Unfortunately the patch only corrects some of the
		problems with the header file, so it is still
		necessary to distribute a private patched version
		of it with the lsof sources.

		Applied a man page correction reported by Frederic
		Delanoy <max_ok@yahoo.com>.

		Corrected cast bugs related to using the HP-UX
		bundled C compiler on HP-UX 11.11.

4.63		April 23, 2002
		Added HPUX_BOOTFILE environment variable for use
		by the Configure script in determining HP-UX kernel
		configuration information -- e.g., the state of
		the ipis_s structure in the HP-UX 11 kernel.  The
		change was suggested by Marc Bejarano <beej@alum.mit.edu>.
		Marc also suggested some changes to the HP-UX
		section in 00FAQ that discusses Configure's use of
		q4 for HP-UX 11.

		Fixed a bug in the Solaris lsof file system matching
		code.  It was not reporting that VCHR files in
		/devices were in / when /devices was in /, too.

		Corrected bugs in device number, file size, file
		offset, and raw device number field output generation.

		Added recognition of OpenBSD 3.1 to the Configure
		script with a suggestion from Peter Valchev
		<pvalchev@sightly.net>.  Note that this change does
		not constitute a claim that lsof works on OpenBSD
		3.1, because I haven't tested it there.

		Built an automated test suite.  (See 00TEST and
		the tests/ sub-directory of the lsof main directory).
		Bela Lubkin requested it.  Dale Talcott, John
		Hughes, and Larry Rosenman helped me validate it
		on their systems.

		During the development of the test suite I discovered
		the following lsof bugs or missing features, and
		corrected or supplied them.

		* Corrected the reporting of locks for:
		  o Digital UNIX 4.0d and Tru64 Unix 5.[01];
		  o HP-UX 10.30 and 11.00;
		  o OpenUNIX 8;
		  o UnixWare 7.1.1.

		* Enabled HP-UX 10.30 and 11.00 to report open NFS
		  file link counts.

		* Corrected the reporting of UNIX domain socket
		  names for Apple Darwin, FreeBSD 4.5 and above,
		  NetBSD 1.4.1 and above, and for OpenBSD 3.0 and
		  above.

		* Enabled HP-UX 11.11 to stat(2) large files.

		* Fixed handling of combination 32 and 64 bit
		  device numbers in AIX 64 bit architectures.

		Updated the AIX 4.3.3 NFS rnode recognition code,
		first installed at revision 4.51.  It looks like
		some IBM update has restored a single rnode structure
		independent of the machine bit width.

		Updated the NetBSD and OpenBSD sources so NetBSD
		can process DTYPE_PIPE files, as OpenBSD was already
		able to do.

		Updated Darwin get-xnu-headers.sh script to reflect
		information about a recent reorganization of the
		Darwin CVS hierarchy, supplied by Allan Nathanson
		<ajn@apple.com>.

		Added defense against the standard I/O descriptor
		attack.

4.64		June 26, 2002
		Corrected some FreeBSD pre-processor directives.
		David O'Brien <obrien@NUXI.com> pointed them out.

		Updated lsof's main() function to: 1) close all
		open file descriptors above 2 before starting; and
		2) to set a non-interfering umask.  Moved GET_MAX_FD
		test from misc.c to proto.h, so that main() could
		use it.  Added multiple-include protection to
		proto.h.

		Moved FAQ's test suite Q's & A's to a more appropriate
		section.  Added a Q&A on HASSECURITY option and
		its affect on searching for open files.  (That was
		already in the man page.)

		Updated hpux/kmem/dnode.c for HP-UX < 11 compilation
		with information from John Dzubera <Zube@CS.ColoState.EDU>.
		While lsof doesn't support HP-UX < 11 any more, I
		try to avoid disabling it there when possible, and
		a locking fix for HP-UX >= 11 in lsof 4.63
		inadvertently disabled compilation of lsof for
		HP-UX < 11.  Fixed long-standing bug in HP-UX 10.20
		lock reporting.

		Removed language from the test suite programs that
		requires an ANSI-C compiler.  This allowed the test
		suite to be validated with cc and gcc on the un-
		supported HP-UX 10.20.

		At the suggestion of Manuel Bouyer <bouyer@antioche.eu.org>
		switched NetBSD and OpenBSD lsof from using nlist()
		to using kvm_nlist().  Made the same change for
		BSDI, Darwin, and FreeBSD.

		Validated test suite on OPENSTEP 4.2.

		In response to a suggestion from Jeff Stoner
		<jstoner@blackboard.com> enhanced support for the
		FD list of the -d option to allow it to be either
		an exclusion or inclusion list, using the '^' prefix
		to denote exclusions.

		Made adjustments for FreeBSD 4.6 and 5.0-CURRENT.
		Fixed a FreeBSD /etc/make.conf CFLAGS extraction
		bug, reported by Kris Kennaway <kris@obsecurity.org>,
		and new a bug in the fix, reported by Eric Cronin
		<ecronin@eecs.umich.edu>

		Added nullfs support for FreeBSD, NetBSD, and OpenBSD
		at the request of Andrew Brown <atatat@atatdot.net>.

		Modified all readmnt() functions to ignore mounted-on
		directory names that don't begin with '/'.

		Tested on NetBSD 1.6A and OpenBSD 3.1.

		Upgraded to Solaris 9 FCS with two changes to the
		BETA-Refresh support: 1) an adjustment to dnode.c
		for a change in the so_so (sonode) structure; and
		2) addition of Solaris 9 FCS specific DNLC code.
		David Comay <David.Comay@Eng.Sun.COM> sent me the
		dnode.c change and Casper Dik <Casper.Dik@sun.com>
		helped with the new DNLC support code.

		Applied OpenUNIX changes that permit lsof to compile
		and run on the upcoming 8.0.1 release.  The changes
		were supplied by Robert Lipe <robertl@caldera.com>.
		Larry Rosenman <ler@lerctr.org> provided a test
		system.

		Added Solaris fd file system support.

4.65		October 10, 2002
		Adjusted for change in FreeBSD 5.0-CURRENT inode
		structure, reported by David O'Brien <obrien@NUXI.com>.
		Adjusted for changes in FreeBSD 5.0-CURRENT <sys/vnode.h>.
		One change was reported by Anders Nordby
		<anders@FreeBSD.org>.  Adjusted for FreeBSD 5.0-CURRENT
		on sparc64 architecture.

		Enhanced the error reporting of Solaris lsof when
		it detects a kvm_open() failure, and added a 00FAQ
		entry on the cause, based on a report from Peter
		J. Bertoncini <pjb@anl.gov>.

		Enabled compiling of lsof for NetBSD 1.5 with the
		NULL file system, using a patch from Andrew Brown
		<atatat@atatdot.net>.

		Removed a hack in the LTbigf test program that was
		once needed when it was compiled on Solaris 9 BETA-
		Refresh with gcc.  The hack isn't needed on Solaris
		9 FCS.  Janet Hempstead <jan@library.carleton.ca>
		brought the need for this change to my attention.

		Applied a patch, supplied by Andrew Brown
		<atatat@atatdot.net>, that updates lsof for NetBSD
		version 1.6F.  Corrected handling of the NetBSD
		nullfs.

		Updated to BSDI BSD/OS 4.3 on a test system kindly
		provided by Terry Kennedy <terry@tmk.com>.

		Updated to FreeBSD 4.7.

		Updated to Apple Darwin 1.5, 5.x and 6.x with
		patches supplied by Allan Nathanson <ajn@apple.com>.
		The patches include IPv6 support.

		Updated Configure to use the -bnolibpath loader
		option when building lsof on a PowerPC, running
		AIX 5 or greater.  Valdis Kletnieks
		<Valdis.Kletnieks@vt.edu> informed me this was
		needed.  Lsof for AIX 5.x was initially developed
		on the IA64, where -bnolibpath can't be used and
		I didn't think to restore it to PowerPC loads when
		AIX 5.x became available for that architecture.

		Updated to UnixWare 7.1.3 on a test system provided
		by Larry Rosenman <ler@lerctr.org>.  Removed claims
		that lsof works on OpenUNIX 8.0.1, because UnixWare
		7.1.3 is the release name of OpenUNIX 8.0.1.

		Based on a comment that his e-mail address was
		wrong in the lsof distribution from Kenneth Stailey
		<kstailey@disclosure.com>, removed all e-mail
		addresses from lsof documentation files except this
		one, 00DIST.  The addresses in 00DIST are used to
		send revision release notices to those who contributed
		to a revision, but the addresses in this file for
		previous revisions and in other documentation files
		sometimes grow stale and are never validated.

4.66		December 22, 2002
		Acquired Solaris 7 and 8 test systems, courtesy of
		John Dzubera <Zube@CS.ColoState.EDU>.  Updated
		00TEST and tests/TestDB accordingly.

		Clarified FreeBSD 5.0 architecture claims at the
		suggestion of David O'Brien <obrien@NUXI.com>.
		Also implemented David's suggestion to change
		Intel to x86.

		Installed changes to DNLC handling in OSR lsof in
		preparation for handling changes in the OSR 5.0.7
		DNLC cache.  Information about the changes and
		patches to handle them were supplied by Bela Lubkin
		<filbo@deepthought.armory.com>.

		Upgraded True 64 UNIX support to the 5.1B release
		on a test system provided by Berkley Shands
		<berkley@cse.wustl.edu>  Had to used relaxed ANSI
		compilation because of an error in a system header
		file and other lsof source usages.

		Implemented the HASNOSOCKSECURITY compile-time
		option.  When it and HASSECURITY are defined, lsof
		will be built to list only the user's open files,
		but will also list anyone else's open socket files,
		provided the "-i" option selects their listing.
		Updated the Customize script to ask about setting
		HASNOSOCKSECURITY.  Left it undefined in all dialect
		machine.h header files.  This change was requested
		by Kenneth Stailey <kstailey@speakeasy.net> for
		use with ntop.

		Added support for OpenBSD 3.2 and its kernel trace
		file.

		Improved lsof help (-h) and version (-v) information
		reporting.

		Fixed a FreeBSD 4.7 and above off-by-two UNIX domain
		socket path termination bug, reported by Ken Stailey
		<kstailey@speakeasy.net>

4.67		March 27, 2003
		Began the transition of the lsof ftp server host
		name from vic.cc.purdue.edu to lsof.itap.purdue.edu.
		That reflects Purdue organizational changes.  This
		first step makes the new name an alias to the old
		one.   The old name, vic.cc.purdue.edu, will remain
		usable for an extended period.

		Corrected a revision number reference in section
		17.17 of 00FAQ on the appearance of Solaris negative
		DNLC caching handing.

		Updated 00FAQ discussion of compilers for 64 bit
		Solaris.

		Validated test suite for 64 bit Solaris 8 and gcc.

		At the request of Alek O. Komarnitsky <alek@komar.org>
		added the "+c <width>" option to enable optional
		changing of the COMMAND column output maximum width
		from the default to <width>.  The default maximum
		width remains CMDL, as defined in lsof.h.

		Fixed three AIX kernel bit size detection bugs,
		one in the AIX Configure script stanza, the second
		and third in the AIX dproc.c get_kernel_access()
		function.  The bugs were reported by Pierre-Yves
		Fontaniere <pyf@cc.in2p3.fr>, who tested the fixes.

		Added kernel event queue file support for FreeBSD,
		NetBSD and OpenBSD.  Andrew Brown <atatat@atatdot.net>
		supplied the code.

		Updated to AIX 5.2 on a test system provided by
		Dale Talcott <dtalcott@purdue.edu>.  Had to build
		work-arounds for two missing AIX 5.2 header files,
		<j2/j2_snapshot> and <proc/proc_public.h>.  Corrected
		an off-by-one UNIX socket addressing bug.  Taught
		AIX lsof to handle both jfs and jfs2 files at the
		same time.  Adjusted for an IBM mistake in the
		sizing of the fdsinfo structure in <procinfo.h>
		Toshiya Nakamura <TOSHIYAN@jp.ibm.com> helped test,

		Updated to FreeBSD 4.8.  Corrected another bug in
		FreeBSD UNIX domain socket name handling.

		Corrected gcc build problems on HP-UX 11i, reported
		by Yuliy Minchev <yuliy@mobiltel.bg>.

		Updated BSDI BSD/OS support to 4.3.1.

		Augmented a lock ID test on NetBSD to check if the
		ID is an LWP pointer.

4.68		June 18, 2003
		Enhanced Configure script's cleanup operations.

		Added support for OpenBSD 3.3, based on a report
		from Peter Valchev <pvalchev@sightly.net>.

		Improved the description of the detached PGP
		signature certificate file in the main lsof README
		file, based on a suggestion from Diana Stockdale
		<diana@mpl.ucsd.edu>.

		Installed a work-around for FreeBSD 5.0-CURRENT on
		Alpha to avoid a compiler register use complaint.

		Corrected a 'c' option error message.  Gnele
		<blaadeleng@yahoo.com> reported the problem.

		Upgraded EXT2FS and UFS support for NetBSD and
		OpenBSD to handle new inode information, and the
		fast UFS1 and UFS2 file systems.
		
		With the help of Andrew Brown <atatat@atatdot.net>
		determined the NetBSD snapshot (1.6F) at which
		<sys/mount.h> could be included under _KERNEL, thus
		eliminating the lsof netexport.h hack.  The same
		change applies to OpenBSD versions 3.3 and above.

		Applied a patch from Armin Gruner <ag@muc.de> that
		corrects the use of the HASPROCFS definition in the
		FreeBSD dialect sources.

		Corrected spelling errors in 00FAQ and in the
		generated 00.README.FIRST_<version> file of the
		distribution archive.  John Jackson <jrj@purdue.edu>
		and Ray Phillips <r.phillips@jkmrc.uq.edu.au>
		spotted and reported the errors.

		Corrected a spelling error in a comment and incorrect
		use of an alarm function in the LTsock test program.

		At the suggestion of Stuart Anderson <sba@srl.caltech.edu>
		added preliminary (and incomplete) SAM-FS file system
		support to Solaris lsof.  Completion awaits availability
		of SAM-FS internals.

		Fixed a Solaris device name printing bug, reported by
		Ric Anderson <ric@tick.Telcom.Arizona.EDU>, only
		visible when HASDCACHE is not defined.  Ric helped
		test the fix.

		Fixed an AIX kernel bit size handling bug related
		to the NFS node (rnode) structure.

		Corrected a print_kptr() function call error in the AIX
		AFS code, reported by David Steiner
		<david.r.steiner@Dartmouth.EDU>.  Upon further reflection
		and because I no longer have appropriate AIX AFS test
		systems, disabled AIX AFS support in the Configure script
		for AIX versions above 4.3.3.0 or AIX AFS versions above 3.5.

		Added support for FreeBSD 5.1.

		With advice from Allan Nathanson <ajn@apple.com> adjusted
		the Darwin get-xnu-headers.sh script to access the kernel
		header files needed by lsof from a new form of the Apple
		open source repository.

		Installed Linux and lsof library bug fixes and
		improvements, supplied by Marian Jancar <mjancar@suse.cz>.
		One Linux improvement handles mount strings that
		have octal escapes in them, eg., \040 for embedded
		blanks.  Marian tested the changes.

4.69		October 16, 2003
		Received and applied an OpenBSD patch from Peter Valchev
		<pvalchev@sightly.net> that replaces a ctob() call with
		a sysconf() call.  Peter claims sysconf() is needed for
		OpenBSD on SPARC.  (It is not needed for NetBSD on SPARC.)

		With the upgrade of my only Solaris 7 test system
		to, Solaris 8, dropped the *claim* that lsof works
		on Solaris 7.  That doesn't mean it won't work
		there, so those who want lsof for Solaris 7 probably
		should be able to build it there and it probably
		will work there.

		Revised lsof's DNLC handling for BSD derivatives,
		including: BSDI; Darwin, DEC OSF/1, Digital UNIX
		and Tru64 UNIX; FreeBSD; NetBSD; and OpenBSD.  The
		latest NetBSD distribution's dropping of the vnode
		capability ID (v_id) required the revision.

		Adjusted to the latest FreeBSD 5.1-CURRENT.

		Added NetBSD support for using kvm_getproc2().

		Added a patch from Andrew Brown <atatat@atatdot.net>
		to handle NetBSD enum conflicts and changes in the
		<miscfs/kernfs/kernfs.h> and <miscfs/procfs/procfs.h>
		header files.

		Added a "#define _KERNEL" to the AIX dnode2.c source
		file for compatibility with a new <j2/j2_inode.h>
		AIX 5.2 header file version.  The addition was
		supplied by Dick Dunbar <Dick.Dunbar@Siebel.com>
		and was offered as a patch to lsof 4.68/

		Added support for a second type of Solaris SAMFS.
		Stuart Anderson <sba@srl.caltech.edu> provided the
		support.  SAMFS support in lsof SOLARIS remains
		scanty, because Sun won't release any details on
		its kernel structures.

		Dropped the *claim* that lsof works on AIX 4.3.3,
		because I was unable to test it there.  That doesn't
		mean it won't work there, so those who want lsof
		for AIX 4.3.3 probably should be able to build it
		there and it probably will work there.

		Updated for Solaris 10 on test systems provided by
		Mike Miscevic <miscevic@hotpop.com>.  Casper Dik
		<casper@holland.sun.com> provided significant help.
		During the Solaris 10 port found and fixed an lofs
		handling bug that prevented reporting of open lofs
		file lock status.

		Updated the DNLC test, LTdnlc, to provide a possible
		explanation about file systems on which the test
		might fail.

		Modified the procedure for obtaining missing Darwin
		XNU kernel header files.  The new one requires more
		manual intervention, but is the best that can be
		done with the way Apple open sources are now
		organized.  00FAQ explains the new procedures for
		those not used to downloading Apple open source
		files.

		Added support for Apple Darwin 7.0 (Mac OS X 10.3)
		with patches supplied by Allan Nathanson <ajn@apple.com>.
		Dropped the *claim* that lsof builds and works on
		Apple Darwin below 6.0.

		Validated lsof on FreeBSD 4.9, using a test system
		provided by Ben Lewis <bl@purdue.edu>.

		Validated lsof on FreeBSD 5.1-CURRENT for Amd64.
		David O'Brien <obrien@FreeBSD.org> provided a test
		system.

		Changed the NetBSD Configure stanza to do header
		file searches in /usr/include by default.  The
		LSOF_INCLUDE and NETBSD_SYS environment variables
		may still be used to specify other search paths.
		Discussions with Andrew Brown and Wolfgang S.
		Rupprecht <wolfgang@wsrcc.com> led to the change.

4.70		January 16, 2004
		Improved shell-portability of the linux stanza of
		the Configure script with a patch from Paul Jarc
		<prj@po.cwru.edu>.

		Added a "silent" rule to tests/Makefile for Paul.
		Updated, extended and clarified the test suite
		documentation in 00FAQ and 00TEST.

		Fixed Solaris 10 dlsof.h typo, reported by Mike
		Miscevic <miscevic@hotpop.com>.  The typo prevents lsof
		from loading cleanly in Solaris 10 builds past 40.

		Fixed a Solaris HSFS node number reporting bug and
		added a structure definition work-around for Solaris
		10.

		Converted PGP signing to GPG.  My previous PGP key can
		be used, but the gpg "--allow-non-selfsigned-uid"
		option may have to be used when it is imported into a
		GPG key ring.

		Added bz2 compression.

		Updated for OpenBSD 3.4.

		Added a work-around for a missing header file in the
		s10_44 Solaris 10 build.

		Added support for FreeBSD 5.2-BETA and 5.2-CURRENT.

		Updated Linux AX25 support with modifications supplied
		by Lutz Poetschulat <dl9cu@db0zwi.de>.

		Added raw IPv6 support to Linux lsof.

		Improved handling of parameters after "-i@".

		Improved file name test in LTdnlc.c.

		Added loop count controls to the reading of Solaris
		lock chains.  The change was implemented as a result of
		a report from Steve Gonczi <steve@relicore.com>.

		Based on a report from John Jackson <jrj@purdue.edu>,
		enabled a Solaris 10 <sys/lgrp.h> work-around for
		Solaris 9, too.  (Patch 112233 installs an lgrp.h on
		Solaris 9 that needs the work-around.)

		With help from Andrew Brown <atatat@atatdot.net> and
		John Heasley <heas@netbsd.org> added log-structured
		file system (LFS) support for NetBSD and OpenBSD.

		Added AMD64 to the list of FreeBSD 5.x-CURRENT
		supported architectures.  FreeBSD.org provides a test
		system, courtesy of (I believe) David O'Brien
		<obrien@FreeBSD.org>.

		Added a cast to lseek() in the HP-UX /dev/kmem-based
		kread() function to make it work properly with the
		bundled HP C compiler.

4.71		March 11, 2004
		Added text file support to Apple Darwin lsof and
		enabled the lsof executable portion of the LTbasic
		test.  Added support for Darwin kernel queue, POSIX
		semaphore and POSIX shared memory files.  Tested on
		Darwin 7.2 (aka Mac OS 10.3.2).

		Added process_kqueue() function prototypes for FreeBSD,
		NetBSD and OpenBSD.

		Picked some lint in AIX sources, lib/rnmh.c and
		tests/LTsock.c.

		Added "-x [fl]" cross-over option, which enables +d and
		+D processing to cross over symbolic links and|or file
		system mount points.  Discussion with Johan Lindquist
		<johan@smilfinken.net> and Eric Williams (aka The Ghost
		In The Machine) <ewill3@earthlink.net> on Linux news
		groups revealed the need for the option.

		Updated support for UnixWare 7.1.4.

		Added support for the optional reporting of socket
		options, socket states and TCP flags for most currently
		supported dialects. John Smith <lbalbalba@hotmail.com>
		and Tristan Nefzger <tn@bhtrader.com> requested the
		information.  The dialects and their versions for which
		this feature has become available include:

		    AIX 4.3.2 and 5.[12]
		    Apple Darwin 7.2
		    BSDI BSD/OS 4.3.1
		    Digital UNIX and Tru64 UNIX 4.0
		    FreeBSD 4.9 and 5.2
		    HP-UX 11 and 11.11 (aka 11i)
		    NetBSD 1.6ZH
		    OpenBSD 3.4
		    OPENSTEP 4.2
		    OpenUNIX 8
		    SCO OpenServer Release 5.0.6
		    Solaris 2.6, 8, 9 and 10
		    UnixWare 7.1.[134]

		Modified the Configure stanza for HP-UX 11 with better
		q4 detection.  Steve Bonds <3vhmxxm02@sneakemail.com>
		supplied the modification.

		Applied a patch from Mike Miscevic <miscevic@hotpop.com>
		to enable lsof to compile with the zone support in the
		Solaris 10 s10_b51 release.  Added information on lsof
		zone behavior to 00FAQ.

		Added a "-z [z]" option to Solaris 10 lsof.  It enables
		the listing of zone name and can also be used to select
		the listing of processes and their files from specified
		zones.

4.72		July 13, 2004
		Corrected Solaris 10 ZONE column title display bug with
		a patch from Joep Vesseur <Joep.Vesseur@Sun.COM>.  Joep's
		fix was offered as a patch to 4.71.

		Based on a report from Jean-Pierre Radley <jpr@jpr.com>
		about an unexpected GNU uname Configure interaction on
		OSR, and working from information received from Bela
		Lubkin, changed the OSR Configure stanza to use
		/bin/uname instead of uname.  Added an FAQ entry about
		Configure version detection problems.

		Added the +m and "+m m" options in response to a dialog
		with Robert T. Brown <rbrown@netmentor.com>.  The
		options allow the creation of a mount table supplement
		file which can be used on selected dialects to get
		device numbers when stat(2) and lstat(2) can't deliver
		them.  (That's generally the result of an inaccessible
		NFS server.)  Currently the new options are supported
		only on Linux.

		Made cpumask_t typedef _KERNEL compensation for FreeBSD
		5.2-CURRENT.  Refined it for 5.2.1-RELEASE with testing
		help from Scott Ellentuch <tuc@ttsg.com>.

		Added support for FreeBSD 4.10.  Larry Rosenmann
		<ler@lerctr.org> kindly provided a test system.

		Added support for NetBSD 2.0 with patches supplied by
		Andrew Brown <atatat@atatdot.net>.  Andrew also
		provided two test systems.

		Made handling of Linux maps file more robust, based on
		a report from Jan Blunck <J.Blunck@tu-harburg.de>.  As
		a side benefit, made handling of generated stat(2)
		information more flexible.

		As a result of a discussion with Jason Fortezzo
		<fortezza@mechanicalism.net>, adjusted lsof for Solaris
		to obtain the maximum user name length from ut_name of
		the utmpx structure, if <utmpx.h> exists.

		Tested under OpenBSD 3.5.

		Updated 00README information about using gcc (via the
		Configure aixgcc abbrevisiation) to compile lsof on
		AIX.  Ann Janssen <ajanssen@nebook.com> made me aware
		the information was out of date.

		Added an AIX SIGDANGER handler and some 00FAQ sections
		on lsof memory usage after a discussion with Tom Qin
		<tom.qin@citigroup.com> about lsof memory usage.

		Added scripts/sort_res.perl5, contributed by Fabian
		Frederick <fabian.frederick@gmx.fr>.  The script
		displays lsof output sorted by size and path name.

		Improved handling of files on Linux NFS mount points
		that use the root_squash option, based on discussions
		with Paul Szabo <psz@maths.usyd.edu.au>.

		Updated FreeBSD 5.2-CURRENT support, based on a problem
		report from Filippo Natali <filippo@widestore.net>.

		Corrected improper FreeeBSD 5.x-CURRENT #if condition,
		reported by Kim Culhan <kimc@kim.net>.

		Added a Configure script work-around for AIX 5.2 lsof
		with JFS2, compiled by gcc >= 3.3.  The work-around
		was supplied by Florian M. Weps <fmw@hactrn.ch>.

4.73		October 21, 2004
		Added an __XPG4_CHAR_CLASS__ #define before
		#include'ing <ctype.h> on Solaris to restore lsof's
		ability to display special characters such as acute-e.

		Added wide-character (e.g., UTF-8) support where
		possible, prompted by a request from Kyungjoon Lee
		<kjoonlee@gmail.com>.  Some older dialects -- e.g.,
		NetBSD 1.4.1 -- don't support wide characters, so the
		wide character support is enabled by definitions in
		each dialect's machine.h.  Dialects with wide-
		character support are listed in 00FAQ.

		Make a FreeBSD 5.2-CURRENT adjustment for <sys/pipe.h>,
		supplied by Sergey A. Osokin <osa@FreeBSD.ORG>.

		Implemented a Linux feature request made by Jakub
		Jelinek <jakub@redhat.com> that enhances lsof's ability
		to locate UNIX domain sockets whose paths are named as
		arguments.  Jakub supplied suggested code.

		Dropped *claims* that lsof works on AIX below 5.1, SCO
		Dropped *claims* that lsof works on AIX below 5.1, SCO
		Openserver 5.0.4, Tru64 UNIX 5.0, and UnixWare below
		7.1.4.  Lsof will probably build and work on those UNIX
		dialect versions, but I no longer have any way to test
		lsof on them.

		Added support for FreeBSD 5.3 and 6.0.  The FreeBSD
		5.3 support hasn't been tested.

		Added FD test code that will allow dialect versions to
		test FD option selections.  Used the new code in the
		PSTAT-based HP-UX lsof to enable it to avoid scanning
		the mount table when its information is not needed.
		The addition was made in response to a query from
		Harvey Garner <Harvey.Garner@championusa.com> about
		lsof performance in a busy NFS environment.

		Upgraded lsof's AIX support level to AIX 5.3, based on
		a report from Dick Dunbar <Dick.Dunbar@Siebel.com>.  (I
		have not tested lsof under AIX 5.3.)  Based on Dick's
		recommendation and local testing changed the C for AIX
		version 6 and higher -qmaxmem option value to -1.

		Made LSOF_AR environment variable more useful and
		documented it in 00XCONFIG.

		Corrected the use of sum(1) to generate signatures for
		the lsof distribution and binaries to match the
		documentation that claims it is sum -r output.  Jin
		Guojun <jin@george.lbl.gov> noticed and reported the
		problem.

		Tested under OpenBSD 3.6.

		Added checksum and GPG certificate files for the bz2,
		gz and Z lsof distribution archives.  The new files
		reside with the distribution archives and supplement
		the signature information already inside the archives.

		Validated on Solaris 10, i8xpc, build s10_63.

4.74		January 17, 2005
		Fixed a Solaris segment fault bug on systems that lack
		a /dev/allkmem device.  Offered the fix as a patch to
		lsof 4.73.  The bug was reported by Donald Zoch
		<donald.zoch@amd.com>.

		Updated lsof for FreeBSD 6.0 and higher for a change in
		<sys/vnode.h>, based on a report from Sergey A. Osokin
		<osa@FreeBSD.ORG>.  Made the update available in a 4.74
		'A' edition pre-release.

		Filed an HP bug report about missing pstat(2) CWD info
		for LOFS on HP-UX 11.11 and higher.  The missing CWD
		info was noticed by Ermin Borovac <e.borovac@bom.gov.au>.
		Added info to 00FAQ about the problem, which can cause
		the lsof test suite's LTbasic test to fail.

		Updated the q4-generated tcp_s.h in the lsof
		distribution and added socket option support for HP-UX
		11.00.  Erwin Reyns <ereyns@europarl.eu.int> helped
		test.

		Updated for Solaris 10, build s10_69, with a patch
		supplied by Mike Miscevic <miscevic@hotpop.com>.

		Added v_path support to Solaris 10 lsof.  That relieves
		it of having to read and decode the kernel DNLC, and
		delivers full paths more reliably.

		Added specialized NFS4 support to Solaris 10 lsof.

		Applied Solaris 10 patches to lsof supplied by Casper
		Dik <casper@holland.sun.com>.

		Updated lsof for NetBSD 2.99.10 and tested it on a
		system provided by Andrew Brown <atatat@atatdot.net>.

		Added support for the FreeBSD 6.0-CURRENT f_vnode
		pointer in the file structure.

		Added BSDI, FreeBSD, NetBSD and OpenBSD support for the
		*effnlink member of the inode structure.  This makes
		the lsof LTnlink test run faster on all modified
		dialects and correctly on OpenBSD.

		Added ptyfs support for NetBSD, using modifications
		provided by Andrew Brown.
		
		Changed the netbsd Configure stanza to look by default
		for system header files in both /usr/include and
		/usr/src.  (The NETBSD_SYS environment variable can
		still be used to select an alternate for /usr/src.)

		Corrects two FreeBSD 4.10 RPC/XDR type definitions.

		Added an FAQ Q&A about setuid and setgid restrictions
		in HP-UX 11.11.  The information in the answer was
		supplied by Frank Sanders <frank.sanders@siemens.com>.

		Added abbreviations for AXI FCIO and FSNAPSHOT file
		flags.  Holger VanKoll <Holger.VanKoll@swisscom.com>
		reported the missing FCIO.

		Adjusted lsof's private AIX 64 bit rnode structure for
		64 bit AIX 5.2 systems.  (IBM doesn't distribute a
		correct <nfs/rnode.h> for it.)

		Corrected a Linux socket inode printing bug reported by
		Igor Schein <igor@txc.com>.

		Updated for FreeBSD 4.11.  The support compiles but
		hasn't been tested.

		Back-ported a FreeBSD 6.0-CURRENT fix to FreeBSD
		5.3-RELEASE-p1.  That was done to solve a compilation
		problem reported by Radko Keves <rado@daemon.sk>.

4.75		May 16, 2005
		Dropped the *claim* that lsof works on DEC OSF/1 and
		Digital UNIX, since my last 4.0 test system has been
		removed.  The last tested distribution of lsof on DEC OSF/1
		and Digital UNIX was revision 4.74.  It has been archived
		on lsof.itap.purdue.edu in pub/tools/unix/lsof/OLD/src.

		Added negation forms to the values in the -g (PGID) and
		-p (PID) lists.  Negated PGID and PID values, like
		negated UID or login name values, are applied without
		ORing or ANDing and take effect before any other
		selection criteria are applied.

		At the request of Marcin Gozdalik <gozdal@gmail.com>
		added a -X option for Linux.  The option inhibits the
		reading of the /proc/net/tcp* and /proc/net/udp*
		files.

		Based on a report from David Gutierrez
		<davegu1@hotmail.com> changed DEC OSF/1 process table
		allocation to request memory in smaller increments.

		Based on a report from jayjwa <jayjwa@atr2.ath.cx>
		updated the Customize script to use "tail -n 1" where
		possible.

		Enabled support for FreeBSD 5.4.

		Improved the BSDI, FreeBSD, NetBSD, OpenBSD and Solaris
		kvm_open() and kvm_openfiles() error messages.

		Enabled support for NetBSD 2.99.12.

		Improved HP-UX Configure stanza with help from Piet
		Starreveld <pstarrev@csc.com>.  Picked some lint Piet
		found.

		Enabled IPv6 support for HP-UX > 11.  Piet Starreveld
		helped test it on 11.23, among others.

		Updated for HP-UX 11.23 on the ia64 architecture.

		Updated to latest FreeBSD 6.0-CURRENT, using a test
		system provided by Andrzej Tobola <ato@iem.pw.edu.pl>.

		Added support for SCO OSR 6.0.0 and UnixWare 7.1.4 with
		help from Richard at SCO.

		Corrected a Linux bug in NFS handling, reported by Karel Zak
		<kzak@redhat.com>.  Karel supplied a patch.

		Improved the code for accessing an AIX 3.2 and higher
		sockaddr_un structure, thus eliminating a segmentation
		fault possibility.

		Updated for AIX 5.3.

		Added preliminary (DEBUG) support for the AIX SANFS
		file system.

		Fixed a bug in the Solaris 10 processing of the vnode's
		v_path pointer with code supplied by Edward Jajko
		<ejajko@portal.com>.  The fix was offered as a patch to
		4.74.

		Dropped support for OpenUNIX 8, since a test system is
		no longer available.  Archived an OpenUNIX-only
		distribution of the last revision (4.74) tested on
		OpenUNIX in pub/tools/unix/lsof/OLD/src.

		Tested under Openbsd 3.7.

		Tested under Darwin 7.7.0.

		Enabled building on amd64 Solaris 10 with hints from
		Marc Aurele La France <tsi@ualberta.ca>.  Marc provided
		a test system.

		Supplied a missing quote in the FreeBSD Configure
		stanza.  Carl Cook <Info@quantum-sci.com> reported the
		problem.

		Removed "-O" option from tests/Makefile so that the
		HP-UX bundled compiler won't complain.

4.76		August 30, 2005
		Corrected an example and spelling errors in man page.

		Updated for Apple Darwin 8.x with changes supplied by
		Allan Nathanson <ajn@apple.com>.  Allan also provided a
		test system.

		Completed documentation of CLRLFILEADD in all machine.h
		files.

		At the request of Chris Markle <cmarkle@sendmail.com>
		added partial listen queue length to socket options
		displayed when -Tf is specified.  Partial queue length
		is not reported for all dialects.  (00FAQ lists the
		ones where it is reported.)

		Updated for FreeBSD 7.0 with information supplied by
		Andrzej Tobola <ato@iem.pw.edu.pl>.

		Updated Solaris VxFS support for VxFS versions 4 and
		above with technical advice from Craig Harmer
		<craig_harmer@symantec.com>, Gary Millen
		<gary_millen@symantec.com> and Chuck Silvers
		<charles_silvers@symantec.com>.  Testing help was
		provided by Michael Antlitz <mantlitz@prophasys.com>,
		Steve Ginsberg <steve@dhapdigital.com> and Kenneth
		Stailey <kstailey@yahoo.com>.

		Fixed a Solaris address space map processing bug.
		Janardhan Molumuri <mjanardhan@gmail.com> reported the
		bug and help me identify it.  Made the fix available as
		a patch to 4.75.

		Added support for Solaris 10 port and CTFS files.  The
		CTFS support is imcomplete, because I don't know how
		to get inode number, size and link count.  (There's
		a new 00FAQ entry about that.)

		Investigated a report from Christopher J Warweg
		<warwegc@GAO.GOV> that the CHECKSUMS for the lsof 4.75
		binary for 64 bit Solaris 8 was incorrect.  It was my
		packaging error.  I rebuilt and repackaged the binary.

		Enabled support for Linux map file names with embedded
		spaces.

4.77		April 10, 2006
		Added -X option support for Solaris 10 and above.  When
		-X is specified lsof will report cached v_node path
		names for unlinked files, followed by "(deleted)".
		Improved cached vnode path name handling by adding
		"(?)" to the end of path names of questionable accuracy.
		Updated 00FAQ to reflect these changes.

		Updated for FreeBSD 7.0-CURRENT.

		Fixed name addition spacing bug, reported by Stuart
		Anderson <anderson@ligo.caltech.edu>.  Also updated
		Solaris 10 SAMFS support at Stuart's request.

		Added missing "break;" and another HASSTATVFS test to
		the NetBSD and OpenBSD dnode.c.  Bill Behr
		<bbehr@networkstoragecorp.com> reported those needs.

		Fixed an HP-UX 11 file descriptor "chunk" size problem,
		reported by Per Allansson <per@appgate.com>.  Per helped
		devise the fix and tested it.  This fix was offered as
		a patch to lsof 4.76.

		Updated for FreeBSD 6.0-STABLE and FreeBSD
		6.1-PRERELEASE.

		Updated scripts/sort_res.perl5 with changes supplied by
		Frederick Fabian <fabian.frederick@skynet.be>, the
		author of the script.

		Corrected +|-M man page documentation error, reported
		by Roger Cornelius <rac@tenzing.org>.

		Improved FreeBSD user device random seed generation in
		response to a problem report from Danny Braniss
		<danny@cs.huji.ac.il>.

		Eliminated three syntax error bugs and other compiler
		complaints from the PSTAT-based lsof.  H. Merijn Brand
		<h.m.brand@xs4all.nl> reported the problems and tested
		the fixes.

		Eliminated compiler complaints in the test suite.

		Investigated problems with the building of lsof on
		PA-RISC HP-UX 11.23, based on a report from John
		Orndorff <John.Orndorff@sungard.com>.  Found that
		neither the HP bundled C compiler nor gcc would build
		lsof, but the the HP unbundled ANSI C compiler would.
		Concluded that HP bundled C compiler can't handle
		<gssapi/gssapi.h>.  Devised a work-around to gcc's
		omission of the rpcent structure definition of
		<netdb.h> that allows it to compile lsof's print.c, but
		the resulting binary doesn't run reliably.  Documented
		the situation in 00FAQ.

		Changed reporting of unknown file types.  The number of
		an unknown type is now reported as four octets.  The
		change was made in response to a Linux lsof bug report
		from Karel Zak <kzak@redhat.com>.

		Dropped the *claim* that lsof works on BSDI BSD/OS
		since my last test system has been removed.  The last
		tested distribution of lsof for BSDI BSD/OS was
		revision 4.76.  It has been archived on
		lsof.itap.purdue.edu in pub/tools/unix/lsof/OLD/src.

		As a result of discussing the lsof source tar's MD5
		checksum with Andrew Bell <andrew.bell.ia@gmail.com>,
		changed the description of a suitable MD5 tool in the
		lsof distribution's documentation to name the openssl
		"dgst" command.

		Enabled compilation on Solaris 10 1/06 with a fix sent
		by Jason Fortezzo <fortezza@mechanicalism.net>.  Made
		the fix available as a patch to 4.76.

		Adjusted to FreeBSD 5.5-PRERELEASE.

		Corrected a bug in the lsof library's process_file()
		function to enable the locating of AIX XTI sockets by
		their TCP/IP address values.  The bug was reported by
		Michel Dubois <Dubois@sears.ca>.

		Based on a bug report from Karel Zak <kzak@redhat.com>
		added command name length checking to as many dialects
		as possible (Linux for Karel) for the "-c c" option.

		Updated for OpenBSD 3.[89].  Tested the 3.9 update on a
		system provided by David Mazieres.  I have not tested
		on OpenBSD 3.8, but David reports lsof 4.76 worked
		there.

		Ended regression testing of lsof on 32 bit Solaris 8
		with the ending of access to a test system.  Lsof
		continues to be tested on 64 bit Solaris 8.

4.78		April 24, 2007
		Added more information to the lsof FAQ about missing
		link counts and sizes on Linux files.

		Simplified Linux stat() and lstat() usage.

		Relocated #define's that prevent OpenBSD compilation on
		systems without a /proc file system.  Pieter Bowman
		<bowman@math.utah.edu> reported the problem.

		Added code to avoid processing Linux /proc/<PID>/maps
		file entries with zero device and node numbers.  Some
		such entries now have names associated with them that
		are not path names -- e.g., "[heap]", "[stack]" or
		"[vdso]".  Scott Worley <sworley@chkno.net> reported
		lsof's mishandling of such entries.

		Added SELinux security context support, provided by
		James Antill <james.antill@redhat.com>.  I have not
		tested this, but James and Karel Zak <kzak@redhat.com>
		have.

		Added the #include of <sys/types.h> to Solaris lsof to
		enabled compilation on Solaris 10 6/06.  Peter Harvey
		Peter.Harvey@Sun.COM diagnosed the problem and supplied
		a patch.

		Added better support for JFS2 on AIX 5.2 and 5.3, based
		on bug reports and help from Thomas Braunbeck
		<BRAUNBEC@de.ibm.com> and Tom Whitty <TWHITTY@cerner.com>.

		Documented that lsof supports AIX 5.3 only up through
		maintenance level 1 (ML1).

		Enabled Solaris lsof to locate the AFS vnode operation
		address for OpenAFS 1.4.1.  The fix was supplied by
		Robert Jelinek <Robert.Jelinek@MorganStanley.com>.

		Enabled support for Solaris 10 ZFS.  If the necessary
		ZFS header files aren't found, lsof offers the option
		to drop ZFS support, to use internal, possibly
		inaccurate structure definitions, or to supply a path
		to the missing header files.  Horst Scheuermann
		<Horst.Scheuermann@uni-trier.de> provided a development
		system and helped test the support.

		Corrected a typo in the man page, reported by Eric S.
		Raymond <esr@thyrsus.com>.

		Changed the spelling of macroes to macros in lsof
		source and documentations files, based on a suggestion
		from Josh Soref <timeless@gmail.com> and verification
		with the OED.

		The following dialects are no longer supported: 32 bit
		AIX 5.2, HP-UX 11, OpenStep 4.2, Solaris 2.6, Solaris
		8, True Unix 64 and UnixWare 7.1.4.  Lsof may work on
		them, but I no longer have test systems for them.
		Support for OpenBSD ends at its version 3.9 for lack of
		interest in the port.

		**************** IMPORTANT NOTE ******************
		*                                                *
		* Lsof support has been reduced to the following *

		**************************************************

		Fixed a Solaris VXFS permission problem when accessing
		the VXFS inode offsets.  The bug was reported by
		Gregory A. Ivanov <ivga@mts.ru>.  Gregory tested the
		fix.

		Moved an #include <string.h> later in FreeBSD dlsof.h
		to enable compilation on recent FreeBSD releases.  The
		change was supplied by Roy Marples <uberlord@gentoo.org>.

		Improved Linux /proc file stream reading speed by applying
		an expanded version of a patch from Eric Dumazet
		<dada1@cosmosbay.com> that allocates a page size buffer
		to each stream.  Improved TCP, TCP6, UDP and UDP6 hashing
		by determining the hash bucket count from the /proc/net
		sockstat and sockstat6 files.  The improvement was
		suggested by Eric and he provided sample code.  Eric also
		tested both improvements.

		Modified Configure script to build lsof on FreeBSD
		6.2.  Tested it on a system provided by Larry Rosenman
		<ler@lerctr.org>.

		Fixed a Linux maps file processing bug that prevented path
		names from having an embedded colon.  James Lingard
		<jchl@arastra.com> reported the bug and helped with its
		fix.

		Based on reports from Eric Dumazet and Samuel Thibault
		<samuel.thibault@ens-lyon.org> added support for the
		Linux 2.6.22 kernel's /proc/<PID>/fdinfo files -- i.e.,
		file offset and flags.  Samuel Thibault provided a test
		system.

		Fixed a Linux UNIX socket memory leak, reported by
		Philip Shin <pshin@xceedium.com>.  Phillip supplied the
		fix.

		With generous assistance from HP added support for an HP-UX
		11.23 patch that makes TLI/XTI socket address information
		available.

		Fixed a header file problem for FreeBSD 6.2 on the Alpha
		architecture.  The problem was reported by Pekka Honkanen
		<phonkane@cc.hut.fi>.  Pekka tested the fix.

		Based on a report and using suggested fixes from Karel Zak
		<kzak@redhat.com>, made these changes to Linux lsof: corrected
		a getpidcon() error message; insured that inode numbers are
		handled correctly for their unsigned long long type; and
		improved SELinux handling.  At the request of Alon Bar-Lev
		<alonbl@gentoo.org> added the LINUX_HASSELINUX environment
		variable to enable or inhibit SElinux support unconditionally.

		Updated Configure for FreeBSD 8.0-CURRENT and tested lsof on
		AMD64 there.

		Added a patch provided by Oles Hnatkevych
		<don_oles@able.com.ua> for FreeBSD systems where the root
		file system is on a CD9660 device.

		Added compensation for the disappearance of FMARK and FDEFER
		from the FreeBSD 8.0-CURRENT <sys/file.h>.

		Updated FreeBSD lsof with ZFS support.  Larry Rosenman
		<ler@lerctr.org>, Erwin Lansing <erwin@FreeBSD.org>, Wesley
		Shields <wxs@atarininja.org> and Dmitry Morozovsky
		<marck@rinet.ru> provided test systems.

		Fixed a socket file identification problem reported by
		Pavol Rusnak <stick@gk2.sk>.  Pavol also reported the
		cause of the problem.

		Added the ability to format the repeat mode marker line
		with strftime(3), where the dialect supports the
		localtime(3) and strftime(3) C library functions.  The
		addition was suggested by Mike Depot <mdepot@comcast.net>,
		who also tested it.  The addition required creating a new
		main lsof source module, util.c, that contains functions
		whose compilation conflicts with the general header file
		tree defined by lsof.h and dlsof.h.

		Based on reports from Andrei V. Lavreniyuk
		<andy.lavr@reactor-xg.kiev.ua> and Pav Lucistnik
		<pav@FreeBSD.org> updated the FreeBSD 7.0 and above
		file lock handling to use new locking structures.  The
		update requires a terrible hack to get a definition for
		the lock owner structure from a kernel source module
		into a local lsof header file.

4.80		May 12, 2008
		Updated for a FreeBSD 7.0 and above byte level locking
		change.  The problem was reported by Conrad J. Sabatier
		<conrads@cox.net>, who helped test the update.  Wesley
		Shields <wxs@FreeBSD.org> provided an 8.0-CURRENT test
		system.

		Propagated the FreeBSD 7.0 and above locking changes to
		FreeBSD 6.x, based on a report from Edwin Groothuis
		<edwin@FreeBSD.org>.

		Added warnings for unsupported dialects or versions.

		Added Linux support for the UDPLITE protocol.  Eric
		Dumazet <dada1@cosmosbay.com> supplied a patch.

		Added a missing quote to the Configure script's
		FreeBSD stanza.

		Added a usage.o rule to the HP-UX PSTAT-based
		Makefile.  I mistakenly deleted the rule at revision
		4.79.  The missing rule was reported by Kawaljeet Kaur
		<kawaljeet.malviya@gmail.com> who tested the corrected
		Makefile.

4.81		October 21, 2008
		Updated the Darwin libproc sources with changes from
		Allan Nathanson <ajn@apple.com>.  Tested them on a iMac
		mini, provided by Apple Inc.

		Changed dummy declarations in library source files to
		eliminate complaints about unused variables and empty
		object files.  This change may not work on dialects I
		can no longer test; it has been tested on some versions
		of AIX, Darwin, FreeBSD, Linux and Solaris.

		At the request of Hal Brooks <hal@uga.edu> added support
		for Linux /proc/net/packet files.  Hal tested it.

		Added socket file only performance enhancements to Linux
		and PSTAT-based HPUX lsof.

		Added htonl call around improper usage of INADDR_LOOPBACK;
		report from an Apple engineer forwarded by Allan Nathanson
		<ajn@apple.com>.

		Adjusted for FreeBSD-8.0 change in device number handling.
		The adjustment should work for FreeBSD 5 and above, should
		the 8.0 change be propagated downward.  The problem was
		reported by Pav Lucistnik <pav@FreeBSD.org>.  An updated
		test system was provided by Erwin Lansing <erwin@FreeBSD.org>.

		Reduced AIX support to version 5.3, since test systems with
		older versions are no longer available to me.

		At the request of Marjo F. Mercado <mmercado@xceedium.com>
		and Phil Shin <pshin@xceedium.com> applied some speed
		improvements to lsof, particularly when the files of
		interest are /Internet files -- i.e., selected with lsof's 
		-i" option.  Added a two new options to assist the
		improvements: 1) "-c^<command>" to tell lsof to exclude the
		named command(s); and 2) "-stcp|ud>:[^]state' to tell lsof
		to include in its reporting or exclude ('^') from its
		reporting Internet files in the named states (e.g., LISTEN,
		^CLOSE_WAIT, IDLE, etc.)  For the most part these changes
		apply only to AIX, Darwin, FreeBSD, PSTAT-based HP-UX, Linux
		and Solaris, since those are the only places I could test
		them.  They are controlled by the HASTCPUDPSTATE definition
		in each dialect's machine.h header file.  Marjo and Phil
		provided HP-UX 11.23 and 11.31 test systems.

		Fixed a stat(2) problem on HP-UX 11.31 while testing the
		speed improvements.

		Adjusted for kernel header file changes in FreeBSD
		8.0-CURRENT.  Larry Rosenman <ler@lerctr.org> provided
		a test system.

		Added a warning for Solaris systems where VxFS node info
		can't be obtained from the VxFS utility library.  The
		warning was requested by Tom Matthews <Tom.MATTHEWS@rbs.com>.

		Corrected mishandling of file system path name arguments
		that have trailing slashes, except, of course, the root
		file system, "/".  Allan Nathanson <ajn@apple.com> reported
		the bug.

4.82		March 25, 2009
		Corrected an over-zealous exclusion test that caused
		lsof to report nothing when it was given no arguments
		and built with HASSECURITY and HASNOSOCKSECURITY enabled.
		Joshua Kinard <kumba@gentoo.org> reported the bug and
		supplied information for reproducing it.

		Based on a report from Dan Trinkle <trinkle@cs.purdue.edu>
		corrected use of <sys/utsname.h> for 32 bit Solaris 10
		and above compilations.  Simultaneously eliminated a
		casting complaint in arg.c and updated Configure to use
		the appropriate 64 bit compilation option (-xarch=v9 or
		-m64) with the Solaris Sun C compiler.

		Updated for FreeBSD 7.1-PRERELEASE with information
		supplied by Larry Rosenman <ler@lerctr.org>.

		Updated the Darwin libproc sources with changes from
		Allan Nathanson <ajn@apple.com>.  Tested them on a iMac
		mini, provided by Apple Inc.  Allan also provided man
		page corrections.

		Updated the FreeBSD Makefile to use the ${MAKE} variable
		for ZFS dnode2.c module compilation, based on a suggestion
		from Alexis Ballier <aballier@gentoo.org>.

		Improved the Solaris VxFS library location test, based on a
		suggestion from Jason Fortezzo <fortezza@mechanicalism.net>.
		Jason tested the change.

		Updated Solaris 10 ZFS support for ZFS version 4 and ZFS
		pool version 10, using a test system kindly provided by
		Vladislav Nespor <vladislav.nespor@id.ethz.ch>.  Renata
		Maria Dart <renata@slac.stanford.edu> tested on ZFS
		version 4, verifying that the update works there, too.
		(ZFS pool version 10 is apparently the ZFS version shipped
		with the 10/08 update to Solaris.  The original ZFS
		support targeted ZFS version 3.)

		I still consider ZFS support in Solaris lsof a hack,
		because it depends on a znode structure definition that
		I developed using dbx.  Sun is remiss in not distributing
		the ZFS header files used to build the distributed kernel.

		Because of the znode structure definition hack, I can't
		guarantee that lsof ZFS support will work for any other
		versions of ZFS.

		Solaris 10: adjusted to a change in the way devices are
		stored in the kernel; fixed a problem in zone handling;
		and added rudimentary sharedfs support.  Carson Gaspar
		<carson@taltos.org> reported the device number problem,
		provided a test system, and tested the changes.  Peter
		Vines <psv2b@eservices.virginia.edu> reported the zone
		handling problem and tested the fix.

		Adapted to FreeBSD 8.0-CURRENT changes in device number
		computation.  Problem was reported by Erwin Lansing
		<erwin@FreeBSD.org>.  Larry Rosenman <ler@lerctr.org>
		provided a test system.

		Corrected Solaris Configure test for appropriate VxFS
		library when using gcc to compile lsof.

		Updated for loss of KAME IPv6 FreeBSD accommodations.

		Adapted to FreeBSD 7.2.  Made Configure script recognized
		FreeBSD 6.3.

4.83		January 18, 2010
		Converted Solaris 10 and above ZFS support to use the CTF
		debugger library, libctf.  Code was supplied by Robert
		Byrnes <Robert.Byrnes@deshaw.com>.

		Corrected a typo in the testing of the LINUX_HASSELINUX
		environment variable in the Configure script.  The error
		was reported by Mike Frysinger <vapier@gentoo.org>.
		At Mike's request made Configure script accept LSOF_RANLIB
		(ranlib command), LSOF_CFGF (additional configuration flags)
		and LSOF_CFGL (additional library specifications) from the
		environment.

		Enabled complilation of Solaris 10 lsof after a recent Sun
		patch which changed the PC file system's structure. Peter
		Vernam <pvernam@draper.com> reported the problem and helped
		with the fix.

		Made the sort of configuration CFLAGS in the CkTestDB
		script impervious to locale settings.

		Ported to Solaris 11, using a test system kindly provided
		by David Day <dday76@gmail.com>.

		Adjusted to the disappearance of <nfs/rpcv2.h> in FreeBSD
		8.0-BETA1.

		Changed Solaris node type lookup to a hashed method and
		added some ability for it to handle duplicate vnodeop names
		in /dev/ksyms.

		Updated for FreeBSD 9.0-CURRENT.  Andrzej Tobola
		<ato@iem.pw.edu.pl> provided a test system.  Extends the
		fix to FreeBSD 6.0 and above via a Configure test and a
		compile-time definition.  The need for the extension was
		reported by Erik Trulsson <ertr1013@student.uu.se>>

		Made corrections to FAQ typographical errors, suggested
		by Josh Soref <timeless@gmail.com>.
		
		Added __UCLIBC__ test to Linux dlsof.h so lsof would compile
		on an Intel ARM XScale processor.  The addition was provided
		by Doug Kehn <rdkehn@yahoo.com>.

		Added test for <utmpx.h> to FreeBSD configuration.  Improved
		its use in lsof.h.  The changes were supplied by Martin Wilke
		<miwi@FreeBSD.org>.

4.84		July 29, 2010
		Fixed a man page nroff command error with a correction
		supplied by Josh Soref <timeless@gmail.com>.

		Made Configure script recognize FreeBSD 7.3.  Larry Rosenman
		<ler@lerctr.org> provided a test system.

		Improved task support, initially for Linux only, with help
		provided by Jerome Marchand <jmarchan@redhat.com> and
		Miklos Szeredi <mszeredi@suse.cz>.  The support includes a
		new compile-time definition, HASTASKS, and a new run time
		option, "-K" to select task reporting.

		While adding help output support for "-K", reorganized the
		printing of help columns to make it much easier to add a new
		option description.

		Updated the Solaris PC file system structure patch in
		revision 4.83 so it will compile with gcc.

		Disabled the Solaris lgrp_root work-around in the Solaris
		machine.h so it won't cause compilation problems on Solaris
		11.  It no longer causes compilation problems on my Solaris
		9 and 10 test systems, but some older Solaris 9 and 10
		versions may still need it, so the work-around was left in
		the Sun machine.h and a FAQ entry was created about it.

		Updated for Solaris 11 b134, using a test system kindly
		provided by Carson Gaspar <carson@taltos.org>.  Made
		provisions for the next ZFS version.  Added info about
		the failure of the LTnlink test on ZFS file systems.

		Corrected typo in Configure script, reported by Dmitry
		Berezin <dmitryb@oit.rutgers.edu>.

4.85		September 27, 2011
		John Dzubera <Zube@CS.ColoState.EDU> kindly provided a patched
		Solaris 9 test system with the lgrp_root conflict and I was
		able to devise an automatic work-around for the conflict.  The
		special note in .../dialects/sun/machine.h was removed and
		the 17.28.1 FAQ entry was modified to reflect the update.

		Added a Solaris 11 work-around for a typedef problem with
		<sys/mutex.h>.  Carson Gaspar <carson@taltos.org> reported
		the problem and supplied the work-around.

		Added support for FreeBSD 7.4 and 8.2; tested on systems
		provided by Larry Rosenman <ler@lerctr.org>.

		Added support for 32 bit Solaris 11 lsof with mods supplied
		by Jan Wortelboer <J.H.P.Wortelboer@uva.nl>.

		Added Solaris 11 support for using an alternate genunix
		location.  Bill Goodridge <bill@its.brooklyn.cuny.edu>
		reported the alternate location.

		Added further Linux cross configuration support to lsof's
		Configure script.  The additional support was supplied by
		Grant Erickson <erick205@umn.edu>.  See the descriptions of
		the LINUX_* environmen  variables in 00XCONFIG for more
		information.  Tested lsof on Linux kernel 2.6.32 and picked
		some lint that surfaced during the test.

		Added fixes and changes for Apple Mac OS X 10.6, provided by
		Allan Nathanson <ajn@apple.com>.  Allan also provided a test
		system.

		Tested on FreeBSD 6.4 i386, using a test system provided by
		Terry Kennedy <TERRY@tmk.com>.  Updated for recent FreeBSD ZFS
		changes on an 8.2 amd64 test system also provided by Terry.

		Changed documentation to indicate FreeBSD 7.x is no longer
		supported, since I no longer have a test system.

		Made some changes to the lsof man page, suggested by Navid
		<evi1m4chine@googlemail.com>.

		Added compensation for Solaris 10 systems that have patch
		144488-10.  The patch requires that the new header file
		<sys/socket_proto.h> be included while _KERNEL is defined.
		Brett Bartick <Brett.bartick@nomura.com> reported the problem
		first, followed by Stuart Anderson <anderson@ligo.caltech.edu>.
		Michael Hocke <michael.hocke@nyu.edu> suggested a work-around
		which I refined to limit it to the specific Solaris 10 instance
		and then tested on a system provided by Charles Stephens
		<cfs@cowlabs.com>

		Added the +|-e option for Linux.  It exempts file systems
		named by path from function calls that might block in the
		kernel -- i.e., stat(2) and lstat(2), and when the +e form
		is used, readlink (2).  The new packager of lsof for the
		Linux Fedora and RHEL distributions, Peter Schiffer
		<pschiffe@redhat.com>, asked for the feature so it could
		be used with Clearcase file systems, whose implementation
		can block stat(2) calls.  I consider this feature very risky
		and easy to misuse -- e.g., specifying the file system as
		'/' would exempt all file systems.  I don't intend to
		propagate this option to any other UNIX dialect that lsof
		currently supports.

		Made FreeBSD 9 adjustment.

		Fixed a Linux bug that prevented the display of paths for
		abstact UNIX sockets.  Masatake Yamato <yamato@redhat.com>
		reported the bug and supplied a patch.

		Added compensation for the removal of RPC header files from
		GlibC 2.14 for Linux.  Marek Behun <kabel@blackhole.sk>
		reported the problem and supplied a patch.

		Added support for Linux Netlink protocol.  Masatake Yamato
		requested the support and supplied a patch.  Peter Schiffer
		<pschiffe@redhat.com> provided a test system.

		Corrected Linux UDP6-lite path.  The error was reported by
		Masatake Yamato and he also supplied a patch.
