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
.
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[_]
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 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 .
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
. 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 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 .
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 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
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 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
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 BSD/OS 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
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
.
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
