Subject: v18i057:  REVISED ofiles, doesn't need Sun source

Here's a new shar of ofiles.  When I saw how little ofiles needed
from /usr/src/sys/specfs/snode.h, I decided to define it in ofiles.c.
This version should now compile for folks who do not have Sun sources.

Sorry for the problem.  I'm just about done with fstat, and I have
made sure it doesn't have the same difficulty.

XXOfiles shows the owner of an open file or network connection.
XX
XXC. Spencer is the original author of ofiles.  Michael Ditto, Tom Dunigan,
XXAlexander Dupuy, Gary Nebbett and Richard Tobin made contributions.  Mike
XXSpitzer, Ray Moody and Vik Lall of the Purdue University Computing Center
XX(PUCC) adapted ofiles to a number of different UNIX environments.  I added
XXthe network connection option.
XX
XXOfiles compiles and runs on 4.3BSD, DYNIX 3.0.12 (Balance) and 3.0.14
XX(Symmetry), SunOS 4.0 and ULTRIX 2.2.  It is free of lint on those systems
XXaccording to the lint libraries in use at PUCC.
XX
XXSpecial notes:
XX
XX    1.  A "generic" Makefile is included.  You may have to adjust it
XX        to your local conditions.
XX
XX    2.  SunOS 4.0 loading requires "-lkvm", so modify the Makefile
XX        accordingly when you port ofiles to your Sun system.
XX
XX    3.  Ofiles needs permission to read /dev/drum (swap files), /dev/kmem
XX        and /dev/mem.  PUCC uses a "setgid kmem" approach - i. e.,
XX        /dev/{drum,kmem,mem} are in the kmem group and ofiles has mode
XX        2755, group kmem.  The Makefile install rule implements this
XX        convention.
XX
XXThe ofiles distribution includes:
XX
XX    README        this file
XX    Makefile    a generic Makefile
XX    ofiles.c    source
XX    ofiles.8l    man page

XX.SH DESCRIPTION
XX.I Ofiles
XXdisplays the owner, process identification (PID), type, command and
XXthe number of the inode associated with an open instance of a file
XXor a network connection.
XX.PP
XXAn open file may be a regular file, a file system or a directory;
XXit is specified by its path name.
XXWhen the path name refers to a file system,
XX.I ofiles
XXwill display the owners of all open instances of files in the system.
XX.PP
XXAn open network connection is specified by the kernel address of its
XXProtocol Control Block (PCB), as displayed by
XX.IR netstat (8),
XXwhen its
XX.B \-A
XXoption is specified.
XX.SH OPTIONS
XX.I Ofiles
XXdisplays information about its usage if no options are specified.
XX.TP \w'-kXnlistXcore'u+4
XX.BI \-d
XXThis option selects verbose, debugging output.
XX.TP
XX.BI \-k \ nlist\ core
XXThis option may be used only on DYNIX hosts.
XXIt sets optional name list and core file paths.
XX.IP
XX.I Nlist
XXis the path to the file from which
XX.I ofiles
XXshould obtain the addresses of kernel symbols,
XXinstead of from
XX.IR /dynix .
XX.IP
XX.I Core
XXis the path to the file from which
XX.I ofiles
XXshould obtain the value of kernel symbols,
XXinstead of from
XX.IR /dev/mem .
XX.IP
XXThis option is useful for debugging system crash dumps.
XX.TP
XX.B \-n
XXThis option specifies that the
XX.I name
XXarguments identify network connections by their hexadecimal, Protocol
XXControl Block (PCB) addresses.
XXPCB addresses can be obtained via the
XX.B \-A
XXoption of
XX.IR netstat (1).
XX.IP
XXThis option makes it possible to determine the local processes that
XXare using network connections in the LISTEN through ESTABLISHED states.
XX.TP
XX.B \-p
XXThis option specifies that
XX.I ofiles
XXshould print process identifiers only \- e. g., so that the output may
XXbe piped to
XX.IR kill (1).
XX.TP
XX.I names
XXThese are path names of files, directories and file systems;
XXor, if the
XX.B \-n
XXoption has been specified, network connections, identified by their
XXhexadecimal Protocol Control Block (PCB) addresses.
XX.SH OUTPUT
XX.I Ofiles

XXor file system;
XXfor network connections, the kernel address linkages, starting with the file

XXProtocol Control Block (INPCB) structure to the PCB

XX.SH DIAGNOSTICS
XXErrors are identified with messages on the standard error file.
XX.PP
XX.I Ofiles
XXreturns a one (1) if any error was detected, including the failure to
XXlocate any
XX.IR names .
XXIt returns a zero (0) if no errors were detected and if it was able to
XXdisplay owner information about all the specified
XX.IR names .
XX.SH BUGS
XX.I Ofiles
XXcan't identify SunOS 4.0 stream files, so it doesn't follow their file
XXstructure pointers correctly when reading their inodes.
XXThat results in the display of erroneous inode numbers for stream files.
XX.PP
XXThe
XX.B \-n
XXoption limits its search to network connections in the LISTEN through
XXESTABLISHED states.
XX.PP
XXSince
XX.I ofiles
XXreads kernel memory in its search for open files and network connections,
XXrapid changes in kernel memory may produce unsatisfactory results.
XX.SH AUTHORS
XXC. Spencer is the original author.
XXMichael Ditto, Tom Dunigan, Alexander Dupuy, Gary Nebbett and Richard Tobin
XXcontributed.
XX.PP
XXMichael Spitzer, Ray Moody, and Vik Lall of the Purdue University Computing
XXCenter converted the program to a variety of UNIX environments.
XX.PP
XXVic Abell of the Purdue University Computing Center added the
XX.B \-n
XXoption.
