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 (PGRP) 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 (PGRP) -- 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 . 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://vic.cc.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[_] and 00RELEASE.SUMMARY_ -- 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 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 on the 6.2 IMPACT distribution. Heddy Boubaker 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 prompted this. 4.02 March 21, 1997 Based on a report from Pasi Kaara , 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 taught HP-UX 10.x lsof to name file systems better by using the virtual file system device number. Elias Halldor Agustsson provided a test system. Changed NEXTSTEP and UNIXWARE Makefiles to use safer quoting when generating version.h. The change was suggested by Bob Farmer . Added SHELL=/bin/sh string to all Makefiles. Added support for Linux 2.1.28 on a test system, kindly provided by Jonathan Sergent . 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 who helped test it. Updated the old get_kernel_syms() code to recognize and skip module name entries. Prompted by Marty Leisner , 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 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 . Terry Kennedy 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 , 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 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 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 helped develop and test the 5.3 definition. John R. Vanderpool 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 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 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 , 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 . 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 . (Configure's -clean argument already did this.) Fixed an incorrect awk argument in the sunos*) Configure stanza, reported by Alexandre Oliva . Added CD9660 (aka ISO) file system support to FreeBSD, NetBSD, and OpenBSD with mods and help from Kenneth Stailey . (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 . Improved the handling of IRIX 5.1 and greater FIFOs. 4.07 May 12, 1997 Based on AIX problem reports from David Capshaw , 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 . 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 . 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 and Jonathan Sergent 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 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 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 , 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 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 . 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 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 . 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 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 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 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 , 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 . 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 . Cleaned up some typos and confusion in Configure's help output, based on comments from Bela Lubkin 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 . Added socket state -- TCO or TPI -- for socket files at the suggestion of Ian Fitchet . 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 deselect 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 . 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, PGRPs, 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 . 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 . 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 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 supplied the changes. Kevin Smith 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 for Solaris 2.x. W. Richard Stevens 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 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 . 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 . 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 PGRP reporting -- but a bug, corrected in revision 4.18, previously made -R unnecessary. Enabled configuring for BSDI 4.0 per a suggestion from Jeff Honig . 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 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 . 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 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 . 4.23 January 16, 1998 Fixed conflict arising from the quondam replacement of the Sun Solaris with a BIND/BSD version. With help from Jonathan Sergent 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 . Added NFS node compensation for NetBSD 1.3. The code and suggestion for it was supplied by Jean-Luc Richier . 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 . 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 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 , enabling lsof to compile for BSDI BSD/OS 2.0. Corrected a documentation error in 00DCACHE, pointed out by Thomas Anders . 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 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 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 . 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 . 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 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 parsable 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 by IRIX 6.4 patch 2536. Added a work-around for it to the lsof Configure script. Igor Schein 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 , 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 , , and .) 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 . The fix was offered as a 4.28 patch. Adjusted for Digital UNIX 4.0D; the spec_node structure is now defined in . Kris Chandrasekhar identified the need for the adjustment. Incorporated a bug fix from Brian McAllister 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 reported the problem. Added a Solaris 2.6 work-around to keep the BIND from colliding with the Solaris . Strengthened the Configure test for /proc-based Linux lsof, based on a report from Marty Leisner . Tested on OpenBSD 2.3. Made AIX changes that allow use with 3.2.5. The changes were suggested and tested by Brett Hogden . 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 . He supplied the correction. This was offered as a patch to 4.29. Had a report from Igor Schein 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 . 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 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 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 provided a test system and Don Draper 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 reported the need for the update. Greg and Roger Klorese provided technical information. Scott McClung 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 . This was offered as a patch to 4.30. Added support for Solaris 2.7 (first Beta release). Mike Sullivan provided technical advice and helped test. Charles Stephens also helped test. Fixed bug in /proc-based Linux that caused it to access /proc/mounts excessively. Marty Leisner 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 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 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 . 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 . 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 provided a test system. Andrew Kephart and Tom Weaver provided technical assistance. Niklas Edmundsson 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 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 supplied the additions and helped with testing. Bill Pemberton 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 supplied technical details. Bracketed HP-UX 11 use of 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 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 . Compensated for ncache element naming differences, introduced at PTX 4.4.2; Kurtis D. Rader 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 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 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 helop 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 requested this. Completed the HP-UX 11 port with support for its optional 64 bit kernel. Rich Rauenzahn 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 . 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'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 . This fix was offered as a patch to 4.35. Updated the Customize script to cause ENTER to use all defaults. Amir J. Katz suggested this and helped test the changes. Updated Solaris ICMP and IP stream handling, based on a report from Igor Schein . Fixed a bug in the Digital UNIX mount table handling, reported by Bob Ward . 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 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 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 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 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 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 . 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 provided a test system. Added support for OpenBSD 2.4 with changes supplied by Kenneth Stailey . 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 and Carl Lindberg . The combined dialect subdirectory is named n+os. One of Carl's changes propagates RC_CFLAGS to the library Makefile. Timothy J. Luoma 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 . Lee Penn 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 . Acquired a new UnixWare 2.x test system, generously provided by Computer Classroom, Inc. -- Matthew Thurmaier , Ken Laing , and Andrew Merril . 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 . 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 . For Bela Lubkin 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 and Maciej Lesniewski . Jeff helped test them on various Linux architectures. Tested on AIX 4.3.2; no changes were required. Doug Crabill 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 . Based on a report from Michael Schmitz 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 " and "+d " options for directory searching. +D searches the entire tree, starting at , including , its contents, and its subdirectory branches; +d searches only 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 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 . Fixed an AIX 4.3+ bug in procinfo struct space allocation, reported by Jeff Stewart . 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 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 , David O'Brien , and John Polstra . 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 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 . This was offered as a patch to 4.40. Installed an HP-UX 11 patch, suggested by Kevin Vajk , 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 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 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 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 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 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 . 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 , 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 . Corrected HP-UX error message about HP-UX 11 q4 usage. Amir Katz reported the correction. Fixed a GlibC 2.1 conflict in /proc-based Linux lsof. Fixed a man page typo reported by Vlad Harchev . 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 . Fixed a PTX real vnode to real inode interpretation bug. Added link count to lsof output. Eric Dumazet 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 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 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 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 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 and Don Draper . 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 . 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 . 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 . 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 . 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 , who provided information and did testing. Enabled IPv6 support code for NetBSD and OpenBSD, conditional on Configure script tests. Wolfgang Rupprecht 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 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 and Andrew Thomas Sydelko 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 . Sylvain Robitaille 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 , who also tested the fix. Added a libc5 library /dev/kmem-based Linux lsof circumvention, supplied by Jason Lingohr . Corrected a bug in -t (terse) AIX output, reported by Wendy Lin . 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 header file. Volker Borchert 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 . Fixed a gawk POSIX-mode pattern error in the Linux /dev/kmem-based Mksrc script, based on a tip from Ambrose C. Li . Fixed a bug in the Tru64 UNIX IPv6 handling, courtesy of a report from Casper Dik . Enabled support for OpenBSD 2.6. Enabled support for BSDI 4.1, based on a report from Jeffrey C Honig 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 helped test. Fixed a DEC OSF/1, Digital UNIX, Tru64 UNIX repeat mode bug, reported by Mayer Ilovitz . 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 . The fix was offered as a patch to 4.45. Added support for INRIA IPv6 to NetBSD. Jean-Luc Richier provided patches and a test system on which to verify them. Added support for AIX 4.3.3. Jeff W. Stewart 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 , 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 , 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 with the patches. The problem was reported by Will Partain . Elias Halldor Agustsson 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 . 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 . 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 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 improved AFS configuration for AIX and Solaris, and updated AIX AFS 3.5 support. Johannes Tax , Hung T. Pham , and Curt Freeland provided test systems. Updated lsof's private rnode definition for AIX 4.3.3, since IBM still doesn't ship the header file and the rnode structure definition in 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 . Adjusted for a FreeBSD 4.0 change in the definition of [_]KERNEL. David O'Brien 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 . 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 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 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 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 . Added code to converted 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 . 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 , 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 . 4.50 June 29, 2000 Added a NetBSD alpha test host, courtesy of Ray Phillips . 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 and Jim Mintha . Forced AIX to use the large-file-enabled versions of lstat (lstat64) and stat (stat64) if 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 and puts -DHASSTAT64 in the Makefile's CFLAGS to make this happen. Fernando A.B. Whitaker reported the problem. This was offered as a patch to 4.48. Enabled Configure script to handle OpenBSD 2.7. Angelos D. Keromytis 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 supplied patches and did testing. David O'Brien 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 for a FreeBSD 3.4 test system. In response to an lsof 3.72 bug report from Jim Mewes , added more kernel address filtering to the lsof function, kread(), that reads Solaris kernel data. In response to a report from Marc Duponcheel , added tests to the /proc-based Linux lsof to ignore file systems of types "autofs" and "pipfs". Based on a report and informatio supplied by Casper Dik , 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 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 . Dan supplied a patch and did FreeBSD testing. Added Configure script recognition of NetBSD 1.5, based on a report from Andrew Brown . Thomas Klausner 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 . 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 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 and Klaus Saggerer USG [saggerer@zk3.dec.com> helped put me in contact with Chang Song , 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 , Thomas Klausner , and Wolfgang Rupprecht 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 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 2.96.2. Both compilers produce a working lsof.
