GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
675 Mass Ave, Cambridge, MA 02139, USA
Everyone is permitted to copy and distribute verbatim copies
of this license document, but changing it is not allowed.
Preamble
The licenses for most software are designed to take away your
freedom to share and change it. By contrast, the GNU General Public
License is intended to guarantee your freedom to share and change free
software--to make sure the software is free for all its users. This
General Public License applies to most of the Free Software
Foundation's software and to any other program whose authors commit to
using it. (Some other Free Software Foundation software is covered by
the GNU Library General Public License instead.) You can apply it to
your programs, too.
When we speak of free software, we are referring to freedom, not
price. Our General Public Licenses are designed to make sure that you
have the freedom to distribute copies of free software (and charge for
this service if you wish), that you receive source code or can get it
if you want it, that you can change the software or use pieces of it
in new free programs; and that you know you can do these things.
To protect your rights, we need to make restrictions that forbid
anyone to deny you these rights or to ask you to surrender the rights.
These restrictions translate to certain responsibilities for you if you
distribute copies of the software, or if you modify it.
For example, if you distribute copies of such a program, whether
gratis or for a fee, you must give the recipients all the rights that
you have. You must make sure that they, too, receive or can get the
source code. And you must show them these terms so they know their
rights.
We protect your rights with two steps: (1) copyright the software, and
(2) offer you this license which gives you legal permission to copy,
distribute and/or modify the software.
Also, for each author's protection and ours, we want to make certain
that everyone understands that there is no warranty for this free
software. If the software is modified by someone else and passed on, we
want its recipients to know that what they have is not the original, so
that any problems introduced by others will not reflect on the original
authors' reputations.
Finally, any free program is threatened constantly by software
patents. We wish to avoid the danger that redistributors of a free
program will individually obtain patent licenses, in effect making the
program proprietary. To prevent this, we have made it clear that any
patent must be licensed for everyone's free use or not licensed at all.
The precise terms and conditions for copying, distribution and
modification follow.
GNU GENERAL PUBLIC LICENSE
TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
0. This License applies to any program or other work which contains
a notice placed by the copyright holder saying it may be distributed
under the terms of this General Public License. The "Program", below,
refers to any such program or work, and a "work based on the Program"
means either the Program or any derivative work under copyright law:
that is to say, a work containing the Program or a portion of it,
either verbatim or with modifications and/or translated into another
language. (Hereinafter, translation is included without limitation in
the term "modification".) Each licensee is addressed as "you".
Activities other than copying, distribution and modification are not
covered by this License; they are outside its scope. The act of
running the Program is not restricted, and the output from the Program
is covered only if its contents constitute a work based on the
Program (independent of having been made by running the Program).
Whether that is true depends on what the Program does.
1. You may copy and distribute verbatim copies of the Program's
source code as you receive it, in any medium, provided that you
conspicuously and appropriately publish on each copy an appropriate
copyright notice and disclaimer of warranty; keep intact all the
notices that refer to this License and to the absence of any warranty;
and give any other recipients of the Program a copy of this License
along with the Program.
You may charge a fee for the physical act of transferring a copy, and
you may at your option offer warranty protection in exchange for a fee.
2. You may modify your copy or copies of the Program or any portion
of it, thus forming a work based on the Program, and copy and
distribute such modifications or work under the terms of Section 1
above, provided that you also meet all of these conditions:
a) You must cause the modified files to carry prominent notices
stating that you changed the files and the date of any change.
b) You must cause any work that you distribute or publish, that in
whole or in part contains or is derived from the Program or any
part thereof, to be licensed as a whole at no charge to all third
parties under the terms of this License.
c) If the modified program normally reads commands interactively
when run, you must cause it, when started running for such
interactive use in the most ordinary way, to print or display an
announcement including an appropriate copyright notice and a
notice that there is no warranty (or else, saying that you provide
a warranty) and that users may redistribute the program under
these conditions, and telling the user how to view a copy of this
License. (Exception: if the Program itself is interactive but
does not normally print such an announcement, your work based on
the Program is not required to print an announcement.)
These requirements apply to the modified work as a whole. If
identifiable sections of that work are not derived from the Program,
and can be reasonably considered independent and separate works in
themselves, then this License, and its terms, do not apply to those
sections when you distribute them as separate works. But when you
distribute the same sections as part of a whole which is a work based
on the Program, the distribution of the whole must be on the terms of
this License, whose permissions for other licensees extend to the
entire whole, and thus to each and every part regardless of who wrote it.
Thus, it is not the intent of this section to claim rights or contest
your rights to work written entirely by you; rather, the intent is to
exercise the right to control the distribution of derivative or
collective works based on the Program.
In addition, mere aggregation of another work not based on the Program
with the Program (or with a work based on the Program) on a volume of
a storage or distribution medium does not bring the other work under
the scope of this License.
3. You may copy and distribute the Program (or a work based on it,
under Section 2) in object code or executable form under the terms of
Sections 1 and 2 above provided that you also do one of the following:
a) Accompany it with the complete corresponding machine-readable
source code, which must be distributed under the terms of Sections
1 and 2 above on a medium customarily used for software interchange; or,
b) Accompany it with a written offer, valid for at least three
years, to give any third party, for a charge no more than your
cost of physically performing source distribution, a complete
machine-readable copy of the corresponding source code, to be
distributed under the terms of Sections 1 and 2 above on a medium
customarily used for software interchange; or,
c) Accompany it with the information you received as to the offer
to distribute corresponding source code. (This alternative is
allowed only for noncommercial distribution and only if you
received the program in object code or executable form with such
an offer, in accord with Subsection b above.)
The source code for a work means the preferred form of the work for
making modifications to it. For an executable work, complete source
code means all the source code for all modules it contains, plus any
associated interface definition files, plus the scripts used to
control compilation and installation of the executable. However, as a
special exception, the source code distributed need not include
anything that is normally distributed (in either source or binary
form) with the major components (compiler, kernel, and so on) of the
operating system on which the executable runs, unless that component
itself accompanies the executable.
If distribution of executable or object code is made by offering
access to copy from a designated place, then offering equivalent
access to copy the source code from the same place counts as
distribution of the source code, even though third parties are not
compelled to copy the source along with the object code.
4. You may not copy, modify, sublicense, or distribute the Program
except as expressly provided under this License. Any attempt
otherwise to copy, modify, sublicense or distribute the Program is
void, and will automatically terminate your rights under this License.
However, parties who have received copies, or rights, from you under
this License will not have their licenses terminated so long as such
parties remain in full compliance.
5. You are not required to accept this License, since you have not
signed it. However, nothing else grants you permission to modify or
distribute the Program or its derivative works. These actions are
prohibited by law if you do not accept this License. Therefore, by
modifying or distributing the Program (or any work based on the
Program), you indicate your acceptance of this License to do so, and
all its terms and conditions for copying, distributing or modifying
the Program or works based on it.
6. Each time you redistribute the Program (or any work based on the
Program), the recipient automatically receives a license from the
original licensor to copy, distribute or modify the Program subject to
these terms and conditions. You may not impose any further
restrictions on the recipients' exercise of the rights granted herein.
You are not responsible for enforcing compliance by third parties to
this License.
7. If, as a consequence of a court judgment or allegation of patent
infringement or for any other reason (not limited to patent issues),
conditions are imposed on you (whether by court order, agreement or
otherwise) that contradict the conditions of this License, they do not
excuse you from the conditions of this License. If you cannot
distribute so as to satisfy simultaneously your obligations under this
License and any other pertinent obligations, then as a consequence you
may not distribute the Program at all. For example, if a patent
license would not permit royalty-free redistribution of the Program by
all those who receive copies directly or indirectly through you, then
the only way you could satisfy both it and this License would be to
refrain entirely from distribution of the Program.
If any portion of this section is held invalid or unenforceable under
any particular circumstance, the balance of the section is intended to
apply and the section as a whole is intended to apply in other
circumstances.
It is not the purpose of this section to induce you to infringe any
patents or other property right claims or to contest validity of any
such claims; this section has the sole purpose of protecting the
integrity of the free software distribution system, which is
implemented by public license practices. Many people have made
generous contributions to the wide range of software distributed
through that system in reliance on consistent application of that
system; it is up to the author/donor to decide if he or she is willing
to distribute software through any other system and a licensee cannot
impose that choice.
This section is intended to make thoroughly clear what is believed to
be a consequence of the rest of this License.
8. If the distribution and/or use of the Program is restricted in
certain countries either by patents or by copyrighted interfaces, the
original copyright holder who places the Program under this License
may add an explicit geographical distribution limitation excluding
those countries, so that distribution is permitted only in or among
countries not thus excluded. In such case, this License incorporates
the limitation as if written in the body of this License.
9. The Free Software Foundation may publish revised and/or new versions
of the General Public License from time to time. Such new versions will
be similar in spirit to the present version, but may differ in detail to
address new problems or concerns.
Each version is given a distinguishing version number. If the Program
specifies a version number of this License which applies to it and "any
later version", you have the option of following the terms and conditions
either of that version or of any later version published by the Free
Software Foundation. If the Program does not specify a version number of
this License, you may choose any version ever published by the Free Software
Foundation.
10. If you wish to incorporate parts of the Program into other free
programs whose distribution conditions are different, write to the author
to ask for permission. For software which is copyrighted by the Free
Software Foundation, write to the Free Software Foundation; we sometimes
make exceptions for this. Our decision will be guided by the two goals
of preserving the free status of all derivatives of our free software and
of promoting the sharing and reuse of software generally.
NO WARRANTY
11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW. EXCEPT WHEN
OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES
PROVIDE THE PROGRAM "AS IS" WITHOUT 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 THE PROGRAM IS WITH YOU. SHOULD THE
PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
REPAIR OR CORRECTION.
12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
POSSIBILITY OF SUCH DAMAGES.
END OF TERMS AND CONDITIONS
Appendix: How to Apply These Terms to Your New Programs
If you develop a new program, and you want it to be of the greatest
possible use to the public, the best way to achieve this is to make it
free software which everyone can redistribute and change under these terms.
To do so, attach the following notices to the program. It is safest
to attach them to the start of each source file to most effectively
convey the exclusion of warranty; and each file should have at least
the "copyright" line and a pointer to where the full notice is found.
<one line to give the program's name and a brief idea of what it does.>
Copyright (C) 19yy <name of author>
This program is free software; you can redistribute it and/or modify
it under the terms of the GNU General Public License as published by
the Free Software Foundation; either version 2 of the License, or
(at your option) any later version.
This program is distributed in the hope that it will be useful,
but WITHOUT ANY WARRANTY; without even the implied warranty of
MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. See the
GNU General Public License for more details.
You should have received a copy of the GNU General Public License
along with this program; if not, write to the Free Software
Foundation, Inc., 675 Mass Ave, Cambridge, MA 02139, USA.
Also add information on how to contact you by electronic and paper mail.
If the program is interactive, make it output a short notice like this
when it starts in an interactive mode:
Gnomovision version 69, Copyright (C) 19yy name of author
Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
This is free software, and you are welcome to redistribute it
under certain conditions; type `show c' for details.
The hypothetical commands `show w' and `show c' should show the appropriate
parts of the General Public License. Of course, the commands you use may
be called something other than `show w' and `show c'; they could even be
mouse-clicks or menu items--whatever suits your program.
You should also get your employer (if you work as a programmer) or your
school, if any, to sign a "copyright disclaimer" for the program, if
necessary. Here is a sample; alter the names:
Yoyodyne, Inc., hereby disclaims all copyright interest in the program
`Gnomovision' (which makes passes at compilers) written by James Hacker.
<signature of Ty Coon>, 1 April 1989
Ty Coon, President of Vice
This General Public License does not permit incorporating your program into
proprietary programs. If your program is a subroutine library, you may
consider it more useful to permit linking proprietary applications with the
library. If this is what you want to do, use the GNU Library General
Public License instead of this License.

Wed Jan 11 13:46:50 1995 Eric Youngdale (eric@localhost)
* mkisofs.c: Modify extension record to conform to IEEE P1282
specifications. This is commented out right now, but a trivial
change to a #define enables this. I need to see the specs
to see whether anything else changed before this becomes final.
* write.c (FDECL4): Fix so that we properly determine error
conditions.
* mkisofs.h: Change rr_attributes to unsigned.
* tree.c(increment_nlink): Change pnt since rr_attributes is now
unsigned.
Ultrix patches from petav@argon.e20.physik.tu-muenchen.de (Peter Averkamp)
* rock.c: Fix for ultrix systems, we have 64 bit device numbers.
Type cast when generating file size. Change rr_attributes to
unsigned.
* mkisofs.c: For ultrix systems, define our own function
for strdup.
* mkisofs.c: Fix usage() since some compilers do not concatenate
strings properly (i.e. ultrix).
Bugs found with Sentinel II:
* write.c: Fix a couple of memory leaks.
* mkisofs.c: Bugfix - always put a zero byte at end of name
for ".." entry.
* tree.c: Set isorec.date from fstatbuf.st_ctime, not current_time,
since current_time might not be set.
Sat Dec 3 14:55:42 1994 Eric Youngdale (eric@andante)
* mkisofs.c: When returning entry for ".." file, set second byte
to 0.

Add some changes to allow more configurability of some of the
volume header fields:
* mkisofs.8: Document new configuration options.

* write.c(iso_write), tree.c, rock.c(generate_rock_ridge_attributes):
Added defines for QNX operation system
* rock.c(generate_rock_ridge_attributes): symbolic links should
not have CONTINUE component flag set unless there are multiple
component records, and mkisofs does not generate these.
st_ctime was stored as the creation time, changed to attribute time.
QNX has a creation time, so that is stored as well under QNX.
Thu Oct 28 19:54:38 1993 Eric Youngdale (eric@kafka)
* mkisofs.c, Makefile (version_string): Bump to 0.99.
* write.c(iso_write): Put hour, minute, second into date fields in
volume descriptor.

the ".." entry in the root directory.
Sat Oct 16 10:28:30 1993 Eric Youngdale (eric@kafka)
Fix path tables so that they are sorted.
* tree.c (assign_directory_addresses): Move to write.c
* write.c (generate_path_tables): Create an array of pointers to
the individual directories, and sort it based upon the name and
the parent path table index. Then update all of the indexes and
repeat the sort until the path table indexes no longer need to be
changed, and then write the path table.
Fix problem where hard links were throwing off the total extent count.
* write.c (iso_write): Call assign_file_addresses, and then
use last_extent to determine how big the volume is.
* write.c (generate_one_directory): Decrement n_data_extents
for hard links to non-directories so that the expected number
of extents is written correctly.
* write.c(assign_file_addresses): New function.
Fri Oct 15 22:35:43 1993 Eric Youngdale (eric@kafka)
The standard says we should do these things:
* tree.c (generate_reloc_directory): Add RR attributes to
the rr_moved directory.
* mkisofs.c(main): Change ER text strings back to recommended
values.
Tue Oct 12 21:07:38 1993 Eric Youngdale (eric@kafka)
* mkisofs.c, Makefile (version_string): Bump to 0.97.
* tree.c (scan_directory_tree): Do not insert PL entry into
root directory record (i.e. !parent)
* tree.c (finish_cl_pl_entries): Do not rely upon name
comparison to locate parent - use d_entry->self instead,
which is guaranteed to be correct.
* mkisofs.h: New variable n_data_extents.
* tree.c: Declare and initialize n_data_extents to 0.
(scan_directory_tree) for non-directories, add
ROUND_UP(statbuf.st_size) to n_data_extents.
(sort_n_finish): Increment n_data_extents for translation tables,
as appropriate.
* write.c(iso_write): Add n_data_extents to the
volume_space_size field.
* hash.c(add_hash): If size != 0 and extent == 0, or
if size == 0 and extent != 0, then complain about
inserting this into the hash table. Kind of a sanity check.
Sat Oct 9 16:39:15 1993 Eric Youngdale (eric@kafka)
* mkisofs.c, Makefile (version_string): Bump to 0.96.
Numerous bugfixes, thanks to a one-off disc from rab@cdrom.com.
* write.c(generate_one_directory): Wait until after we have
filled in the starting_extent field to s_entry before calling
add_hash. This fixes a problem where the hash table gets an
extent of 0 for all regular files, and this turns up when you have
hard links on the disc. (The hash table allows us to have each
hard link point to the same extent on the cdrom, thereby saving
some space).
* tree.c(scan_directory_tree): Set statbuf.st_dev and
statbuf.st_ino to the UNCACHED numbers for symlinks that we
are not following. This prevents the function find_hash from
returning an inode that cooresponds to the file the symlink points
to, which in turn prevents generate_one_directory from filling in
a bogus file length (should be zero for symlinks).
* tree.c(scan_directory_tree): Always call lstat for the file
so that non-RockRidge discs get correct treatment of symlinks.
Improve error message when we ignore a symlink on a non-RR disc.
* write.c(generate_one_directory): Set fields for starting_extent
and size in the "." and ".." entries before we add them to the
file hash. Fixes problems with incorrect backlinks for second
level directories.
Wed Oct 6 19:53:40 1993 Eric Youngdale (eric@kafka)
* write.c (write_one_file): Print message and punt if we are
unable to open the file.
* tree.c(scan_directory_tree): For regular files, use the access
function to verify that the file is readable in the first place.
If not, issue a warning and skip it. For directories, it probably
does not matter, since we would not be able to descend into them
in the first place.
Wed Sep 29 00:02:47 1993 Eric Youngdale (eric@kafka)
* mkisofs.c, Makefile (version_string): Bump to 0.95.
* write.c, tree.c: Cosmetic changes to printed information.
* tree.c(scan_directory_tree): Set size to zero for
special stub entries that correspond to the
relocated directories. Hopefully last big bug.
* mkisofs.h: Change TABLE_INODE, UNCACHED_* macros
to be 0x7fff... to be compatible with signed datatypes.
Mon Sep 27 20:14:49 1993 Eric Youngdale (eric@kafka)
* mkisofs.c, Makefile (version_string): Bump to 0.94.
* write.c (write_path_tables): Actually search the
directory for the matching entry in case we renamed
the directory because of a name conflict.
* tree.c(scan_directory_tree): Take directory_entry pointer
as second argument so that we can create a backpointer
in the directory structure that points back to the original
dir.
* mkisofs.c: Fix call to scan_directory_tree to use new calling
sequence.
* write.c(generate_one_directory): Punt if the last_extent counter
ever exceeds 700Mb/2048. Print name of responsible file,
extent counter, and starting extent. Perhaps we can catch it in
the act.
Sun Sep 26 20:58:05 1993 Eric Youngdale (eric@kafka)
* mkisofs.c, Makefile (version_string): Bump to 0.93.
* tree.c(scan_directory_tree): Handle symlinks better. Either

* Change copyright notice.
Wed Aug 25 08:06:51 1993 Eric Youngdale (eric@kafka)
* mkisofs.c, Makefile (version_string): Bump to 0.91.

* write.c (write_one_file): If the file is large enough, write in
chunks of 16 sectors to improve performance.
* hash.c (add_hash, find_hash, etc): Do not hash s_entry, instead
store relevant info in hash structure (we free s_entry structs as
we write files, and we need to have access to the hash table the
whole way through.
* write.c: Add a few statistics about directory sizes, RR sizes,
translation table sizes, etc.
* tree.c: Use major, not MAJOR. Same for minor. Define S_ISSOCK

easily detect (and look up) filenames that have been accepted
for use in this directory. Used for name collision detection.
* tree.c (sort_n_finish): If two names collide, generate a unique
one (verified with the hash routines). Change the lower priority

This program requires a lot of virtual memory to run since it
builds all of the directories in memory. The exact requirements
depend upon a lot of things, but for Rock Ridge discs 12Mb would not
be unreasonable. Without RockRidge and without the translation
tables, the requirements would be considerably less.
*****************************
Notes for version 1.2.
Minor bugfixes here and there. Support for compiled in
defaults for many of the text fields in the volume header are now
present, and there is also support for a file ".mkisofsrc" that can
also read settings for these parameters.
A short script "Configure" was added to allow us to set up special
compile options that depend upon the system that we are running on.
This should help stamp out the sphaghetti-isms that were starting to grow
up in various places in the code.
You should get more meaningful error messages if you run out of
memory.
*****************************
Notes for version 1.1.
The big news is that SUSP CE entries are now generated for
extremely long filenames and symlink names. This virtually guarantees
that there is no limit (OK, well, about 600Mb) for file name lengths.
I have tested this as well as I can, and it seems to work with linux.
This would only be used very rarely I suspect.
Also, I believe that support for VMS is done. You must be
careful, because only Stream-LF and FIxed length record files can be
recorded. The rest are rejected with error messages. Perhaps I am
being too severe here.
There is a bugfix in the sorting of entries on the disc - we
need to stop comparing once we reach the ';' character.
There are four new options -z -d -D -l -V. Some of these tell
mkisofs to relax some of the iso9660 restrictions, and many systems
apparently do not really seem to mind. Use these with caution.
Some diagnostic programs to scan disc images are in the diag
directory. These are not as portable as mkisofs, and may have some
bugs. Still they are useful because they can check for bugs that I might
have introduced as I add new features.
*****************************
Notes for version 1.0.
In version 1.0, the date fields in the TF fields were fixed -
previously I was storing st_ctime as the file creation time instead of
the file attribute change time. Thanks to Peter van der Veen for
pointing this out. I have one slight concern with this change,
however. The Young Minds software is definitely supplying 3 dates
(creation, modification and access), and I would strongly suspect that
they are incorrectly putting the file attribute change time in the
file creation slot. I would be curious to see how the different RRIP
filesystems treat this. Anyway, this is something to keep in the back
of your mind.
The symlink handling was not quite correct in 0.99 - this is
now fixed. Only some systems seemed to have been affected by this bug.
A command line option is now present to allow you to
specifically exclude certain files from the distribution.
The case where you do not have permissions to read a directory
is now handled better by mkisofs. The directory that cannot be opened
is converted into a zero-length file, and processing continues normally.
A few portability things have been fixed (hopefully).

1) Allow multiple input paths to be concatenated together.
This is a little tricky, because the directory entries need to be
correctly sorted as per iso9660 specifications. It would be better to
force the user to add hard links or copies of the files rather than do
the wrong thing. Leave alone for the time being, I am not sure that
this feature is really needed.
2) For symlinks, we may need to strip out the leading path
information if the link is to an absolute file, and the absolute
address is in the space that we are dumping to the CDROM. Who the
hell knows what we should really do with this, actually. Leave it
for now and see if anyone squalks.
3) Find out if output needs to be written at a particular
blocksize or not.

I am enclosing 3 test programs that I use to verify the
integrity of an iso9660 disc. The first one (isodump) is pretty
simple - it dumps to the screen the contents of the various
directories. The second one (isovfy) goes through and looks for
problems of one kind or another.
To use, type something like "./isodump /dev/ramdisk" or
"./isodump /dev/scd0", depending upon where the iso9660 disc is. It
starts by displaying the files in the first sector of the root
directory. It has some pretty simple one letter commands that you
can use to traverse the directory tree.
a - move back one sector.
b - move forward one sector.
g - go to new logical sector.
q - quit
The a and b commands do not try and stop you from going past the
beginning or end of a sector, and the g command does not have any way
of knowing whether the sector you request is actually a directory or
not.
The output is displayed in several columns. The first column
is the total length of the directory record for the file. The second
column (in [] brackets) is the volume number. Next comes the starting
extent number (in hex), and then comes the file size in bytes. Then
cones the filename (not the Rock Ridge version), and this is preceeded
by an "*" if the file is a directory. After this is a summary of the
Rock Ridge fields present along with a display of the translation of
the symbolic link name if the SL Rock Ridge record is present.
I tailored this program for debugging some of the problems
that I was having earlier. The idea is that you can tailor it
to test for problems that you might be having, so it is not intended
as a be-all and end-all dump program.
If you move to a sector that does not contain directory
information, the results are unpredictable.
The second program, isovfy, is run in the same way as isodump,
except that you do not have to do much except let it run. I have it
written to verify all kinds of different things, and as people find
other sorts of problems other tests could be added.
The third program, dump.c, basically does a hexdump of the cd.
This is screen oriented, and there are some simple commands:
a - move back one sector.
b - move forward one sector.
f - enter new search string.
+ - search forward for search string.
g - go to new logical sector.
q - quit
Note that with the 'g' command, sectors are always given in
hex, and represent 2048 byte sectors (as on the cdrom). If you know
how to decode a raw iso9660 directory, you can pick out the starting
extent number from the hexdump and know where to go from there. The
starting extent appears something like 30 bytes prior to the start of
the iso9660 (not Rock Ridge) filename, and it appears in a 7.3.3
format (meaning that it occupies 8 bytes, 4 in little endian format,
and 4 in big endian format). Thus you should see a mirror image of
the bytes when looking at the extent number.
The isovfy program can also dump the contents of the path
tables, but this capability is commented out right now. Feel free
to enable this to see what is in the tables. Ultimately I may fix
it so that this checks the integrity of the tables as well.
The isovfy program gives warnings about things like files that
have a size of 0 but have an extent number assigned. The mkisofs program
should never do this, but the YM software does leave these around.
I think it is probably harmless in the YM case.~

.SH DESCRIPTION
.B mkisofs
is effectively a pre-mastering program to generate the iso9660 filesystem - it
takes a snapshot of a given directory tree, and generates a binary image which
will correspond to an iso9660 filesystem when written to a block device.
.PP
.B mkisofs
is also capable of generating the System Use Sharing Protocol records specified
by the Rock Ridge Interchange Protocol. This is used to further describe the
files in the iso9660 filesystem to a unix host, and provides information such
as longer filenames, uid/gid, posix permissions, and block and character
devices.
.PP
Each file written to the iso9660 filesystem must have a filename in the 8.3
format (8 characters, period, 3 characters, all upper case), even if Rock Ridge
is in use. This filename is used on systems that are not able to make use of
the Rock Ridge extensions (such as MS-DOS), and each filename in each directory
must be different from the other filenames in the same directory.
.B mkisofs
generally tries to form correct names by forcing the unix filename to upper
case and truncating as required, but often times this yields unsatisfactory
results when there are cases where the
truncated names are not all unique.
.B mkisofs
assigns weightings to each filename, and if two names that are otherwise the
same are found the name with the lower priority is renamed to have a 3 digit
number as an extension (where the number is guaranteed to be unique). An
example of this would be the files foo.bar and
foo.bar.~1~ - the file foo.bar.~1~ would be written as FOO.000;1 and the file
foo.bar would be written as FOO.BAR;1
.PP
.br
.B path
is the path of the directory tree to be copied into the iso9660 filesystem.
.SH OPTIONS
.TP
.I -a
Include all files on the iso9660 filesystem. Normally files that contain the
characters '~' or '#' will not be included (these are typically backup files
for editors under unix).
.TP
.I -A application_id
Specifies a text string that will be written into the volume header.
This should describe the application that will be on the disc. There
is space on the disc for 128 characters of information. This parameter can
also be set in the file .mkisofsrc with APPL=id. If specified in both
places, the command line version is used.
.TP
.I -d
Omit trailing period from files that do not have a period. This violates the
ISO9660 standard, but it happens to work on many systems. Use with caution.
.TP
.I -D
Do not use deep directory relocation, and instead just pack them in the
way we see them. This violates the ISO9660 standard, but it works on many
systems. Use with caution.
.TP
.I -f
Follow symbolic links when generating the filesystem. When this option is not
in use, symbolic links will be entered using Rock Ridge if enabled, otherwise
the file will be ignored.
.TP
.I -l
Allow full 32 character filenames. Normally the ISO9660 filename will be in an
8.3 format which is compatible with MS-DOS, even though the ISO9660 standard
allows filenames of up to 32 characters. If you use this option, the disc may
be difficult to use on a MS-DOS system, but this comes in handy on some other
systems (such as the Amiga). Use with caution.
.TP
.I -N
Omit version numbers from ISO9660 file names. This may violate the ISO9660
standard, but no one really uses the version numbers anyway. Use with caution.
.TP
.I -o filename
is the name of the file to which the iso9660 filesystem image should be
written. This can be a disk file, a tape drive, or it can correspond directly
to the device name of the optical disc writer. If not specified, stdout is
]used. Note that the output can also be a block special device for a regular
disk drive, in which case the disk partition can be mounted and examined to
ensure that the premastering was done correctly.
.TP
.I -P publisher_id
Specifies a text string that will be written into the volume header.
This should describe the publisher of the CDROM, usually with a
mailing address and phone number. There is space on the disc for 128
characters of information. This parameter can also be set in the file
.mkisofsrc with PUBL=. If specified in both places, the command line
version is used.
.TP
.I -p preparer_id
Specifies a text string that will be written into the volume header.
This should describe the preparer of the CDROM, usually with a mailing
address and phone number. There is space on the disc for 128
characters of information. This parameter can also be set in the file
.mkisofsrc with PREP=. If specified in both places, the command
line version is used.
.TP
.I -R
Generate SUSP and RR records using the Rock Ridge protocol to further describe
the files on the iso9660 filesystem.
.TP
.I -T
Generate a file TRANS.TBL in each directory on the CDROM, which can be used
on non-Rock Ridge capable systems to help establish the correct file names.
There is also information present in the file that indicates the major and
minor numbers for block and character devices, and each symlink has the name of
the link file given.
.TP
.I -V volid
Specifies the volume ID to be written into the master block. This
parameter can also be set in the file .mkisofsrc with VOLI=id. If
specified in both places, the command line version is used.
.TP
.I -v
Verbose execution.
.TP
.I -x path
Exclude
.I path
from being written to CDROM.
.I path
must be the complete pathname that results from concatenating the pathname
given as command line argument and the path relative to this directory.
Multiple paths may be excluded (up to 1000).
Example:
mkisofs -o cd -x /local/dir1 -x /local/dir2 /local
.TP
.I -z
Generate special SUSP records for transparently compressed files. This is
only of use and interest for hosts that support transparent decompression.
This is an experimental feature, and no hosts yet support this, but there
are ALPHA patches for linux that can make use of this feature.
.SH CONFIGURATION
.B mkisofs
looks for a file .mkisofsrc, first in the current working directory, and if not
found there then in the directory in which the
.B mkisofs
binary is stored. This file is assumed to contain a series of lines
of the form "TAG=value", and in this way you can specify certain
options. Only the first four characters of the tag are used, and the
case of the tag is not significant. Some fields in the volume header
are not settable on the command line, but can be altered through this
facility. These are the copyright information (COPY), the
bibliographic information (BIBL), the abstract (ABST), the volume set
ID (VOLS) and the system ID (SYSI).
.PP
.B mkisofs
can also be configured at compile time with defaults for many of these fields.
See the file defaults.h.
.SH AUTHOR
.B mkisofs
is not based on the standard mk*fs tools for unix, because we must generate
a complete copy of an existing filesystem on a disk in the iso9660
filesystem. The name mkisofs is probably a bit of a misnomer, since it
not only creates the filesystem, but it also populates it as well.
.PP
.br
Eric Youngdale <ericy@cais.com> wrote both the linux isofs9660 filesystem
and the mkisofs utility, and is currently maintaining them. The copyright for
the mkisofs utility is held by Yggdrasil Computing, Incorporated.
.SH BUGS
Any files that have hard links to files not in the tree being copied to the
iso9660 filessytem will have an incorrect file reference count.
.PP
There may be some other ones. Please, report them to the author.
.SH FUTURE IMPROVEMENTS
Allow specfication of multiple paths on the command line to be included in
iso9660 filesystem. Can be tricky - directory entries in the root directory
need to be properly sorted.
.SH AVAILABILITY
.B mkisofs
is available for anonymous ftp from tsx-11.mit.edu in
/pub/linux/BETA/cdrom/mkisofs and many other mirror sites. With the 1.0
release, it is no longer considered to be in beta testing. Most of the bugs
that are being discovered now are very minor (and interestingly enough also
seem to be present in the YM software). Reports indicate that people are
gearing up for production runs using version 1.00.
