+
+
+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

+ 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.
+
+4.79 April 15, 2008
+
+ **************** IMPORTANT NOTE ******************
+ * *
+ * Lsof support has been reduced to the following *
+ * dialects: AIX, FreeBSD, Linux and Solaris, and *
+ * only in selected versions of those dialects. *
+ * The selected versions are listed in this file *
+ * and in other lsof documentation. *
+ * *
+ * I have made this move because of retirement *
+ * and because I no longer have many test systems *
+ * available to me. *

+
+ 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.
+
+4.86 April 10, 2012
+ Lsof for AIX is no longer supported on any versions of that
+ operating system.
+
+ Added information about the clang compiler for FreeBSD to the
+ FAQ.
+
+ Corrected an arg.c bug in the accumulation of +|-e option
+ values, reported by Peter Schiffer <pschiffe@redhat.com>.
+ This correction was supplied as a patch to revision 4.85.
+
+ Enabled FreeBSD 10 support and tested it there on a system
+ provided by Larry Rosenman <ler@lerctr.org>.
+
+ Updated for latest Solaris 11 with patches supplied by
+ Carson Gaspar <carson@taltos.org>. Carson supplied a test
+ system.
+
+ Adjusted Linux file system search method to compensate for
+ NFS mounts that have duplicate device numbers. The problem
+ was reported by Peter Schiffer <pschiffe@redhat.com>, who
+ provided a test system.
+
+ At the request of Peter Schiffer <pschiffe@redhat.com>, added
+ support for Linux SCTP socket files. Peter provided a test
+ system. Applied a warning patch supplied by Peter.
+
+ Added support for Mac OS X 10.7 (Lion), provided by Allan
+ Nathanson <ajn@apple.com>. Allan also supplied a test
+ system.
+
+ Enabled FreeBSD 8.3 support and tested it there on a system
+ provided by Larry Rosenman <ler@lerctr.org>.
+
+ Corrected the FAQ information on ZFS with Solaris 10 after
+ Steven Blackmon <stblackm@cisco.com> and Prasad Jampala
+ <jampalp@cisco.com> pointed out that it was incorrect --
+ i.e., outdated by the libctf changes at revision 4.83.
+
+ Added code to handle a Linux NFS-mounted root. Jia He
+ <hejianet@linux.vnet.ibm.com> reported the need for this.
+
+4.87 January 2, 2013
+ Added an entry to 00FAQ about lsof behavior when the
+ HASSECURITY and HASNOSOCKSECURITY options are defined.
+ Carson Gaspar <carson@taltos.org> pointed out the need
+ for this clarification.
+
+ Added a work-around for a missing definition of mach_port_t
+ in Darwin 9 (Mac OS/X 10.5.8). The work-around was supplied
+ by Jim Reid <jim@rfc1035.com>.
+
+ Added support for Linux anon_inodefs, provided by Masatake
+ YAMATO <yamato@redhat.com>.
+
+ Documented a Solaris 9 and 10 portmap reporting problem
+ (+M) in 00FAQ. The problem was reported by Clint
+ Roberts <Clint.Roberts@ttius.com>. I have no solution
+ to the problem, but discuss a possible work-around in
+ the answer to this 00FAQ question: "Why doesn't lsof
+ report portmap registrations for some Solaris versions?"
+
+ Added FreeBSD support for the oldnfs and newnfs file system
+ types. Daniel Braniss <danny@cs.huji.ac.il> reported the
+ need for the addition.
+
+ Added ICMP socket support for Linux with code provided by
+ Masatake YAMATO <yamato@redhat.com>.
+
+ Corrected the reporting of process group ID for libproc
+ versions of Mac OS X with a patch from Jeff Trawick
+ <trawick@gmail.com>. The patch has not been applied to
+ Darwin kmem versions, because of little call for them
+ and inadequate test system access. The patch has been
+ tested on Mac OS X 10.8 (Mountain Lion), courtesy of a
+ test system provided by Allan Nathanson <ajn@apple.com>.
+
+ Added thread support to those FreeBSD versions that have
+ ki_numthreads in their kinfo_proc structure. This also
+ activates the -K option for those FreeBSD versions. Jeff
+ Trawick reported problems with FreeBSD lsof when threads
+ are present and this addition solves those problems.
+
+ Made changes to 00FAQ and the distribution, suggested by
+ Warren Young <warren@etr-usa.com>. The 00FAQ changes
+ center on sections that discuss the -s option. The changes
+ to the distribution include a ChangeLog file that is either
+ a pointer to or a copy of 00DIST, the distribution notes.
+
+ Added support to FreeBSD for using the clang compiler.
+
+ Added Linux support for using the getxattr() call to obtain
+ socket protocol identification when it is can't be obtained
+ from the /proc/net files that lsof examines. Masatake YAMATO
+ <yamato@redhat.com> developed the kernel patch to getxattr()
+ and supplied the lsof patch.
