GNU GENERAL PUBLIC LICENSE
Version 2, June 1991
Copyright (C) 1989, 1991 Free Software Foundation, Inc.
59 Temple Place, Suite 330, Boston, MA 02111-1307 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

Installation Instructions
*************************
Copyright (C) 1994, 1995, 1996, 1999, 2000, 2001, 2002, 2004, 2005,
2006 Free Software Foundation, Inc.
This file is free documentation; the Free Software Foundation gives
unlimited permission to copy, distribute and modify it.
Basic Installation
==================
Briefly, the shell commands `./configure; make; make install' should
configure, build, and install this package. The following
more-detailed instructions are generic; see the `README' file for
instructions specific to this package.
The `configure' shell script attempts to guess correct values for
various system-dependent variables used during compilation. It uses
those values to create a `Makefile' in each directory of the package.
It may also create one or more `.h' files containing system-dependent
definitions. Finally, it creates a shell script `config.status' that
you can run in the future to recreate the current configuration, and a
file `config.log' containing compiler output (useful mainly for
debugging `configure').
It can also use an optional file (typically called `config.cache'
and enabled with `--cache-file=config.cache' or simply `-C') that saves
the results of its tests to speed up reconfiguring. Caching is
disabled by default to prevent problems with accidental use of stale
cache files.
If you need to do unusual things to compile the package, please try
to figure out how `configure' could check whether to do them, and mail
diffs or instructions to the address given in the `README' so they can
be considered for the next release. If you are using the cache, and at
some point `config.cache' contains results you don't want to keep, you
may remove or edit it.
The file `configure.ac' (or `configure.in') is used to create
`configure' by a program called `autoconf'. You need `configure.ac' if
you want to change it or regenerate `configure' using a newer version
of `autoconf'.
The simplest way to compile this package is:
1. `cd' to the directory containing the package's source code and type
`./configure' to configure the package for your system.
Running `configure' might take a while. While running, it prints
some messages telling which features it is checking for.
2. Type `make' to compile the package.
3. Optionally, type `make check' to run any self-tests that come with
the package.
4. Type `make install' to install the programs and any data files and
documentation.
5. You can remove the program binaries and object files from the
source code directory by typing `make clean'. To also remove the
files that `configure' created (so you can compile the package for
a different kind of computer), type `make distclean'. There is
also a `make maintainer-clean' target, but that is intended mainly
for the package's developers. If you use it, you may have to get
all sorts of other programs in order to regenerate files that came
with the distribution.
Compilers and Options
=====================
Some systems require unusual options for compilation or linking that the
`configure' script does not know about. Run `./configure --help' for
details on some of the pertinent environment variables.
You can give `configure' initial values for configuration parameters
by setting variables in the command line or in the environment. Here
is an example:
./configure CC=c99 CFLAGS=-g LIBS=-lposix
*Note Defining Variables::, for more details.
Compiling For Multiple Architectures
====================================
You can compile the package for more than one kind of computer at the
same time, by placing the object files for each architecture in their
own directory. To do this, you can use GNU `make'. `cd' to the
directory where you want the object files and executables to go and run
the `configure' script. `configure' automatically checks for the
source code in the directory that `configure' is in and in `..'.
With a non-GNU `make', it is safer to compile the package for one
architecture at a time in the source code directory. After you have
installed the package for one architecture, use `make distclean' before
reconfiguring for another architecture.
Installation Names
==================
By default, `make install' installs the package's commands under
`/usr/local/bin', include files under `/usr/local/include', etc. You
can specify an installation prefix other than `/usr/local' by giving
`configure' the option `--prefix=PREFIX'.
You can specify separate installation prefixes for
architecture-specific files and architecture-independent files. If you
pass the option `--exec-prefix=PREFIX' to `configure', the package uses
PREFIX as the prefix for installing programs and libraries.
Documentation and other data files still use the regular prefix.
In addition, if you use an unusual directory layout you can give
options like `--bindir=DIR' to specify different values for particular
kinds of files. Run `configure --help' for a list of the directories
you can set and what kinds of files go in them.
If the package supports it, you can cause programs to be installed
with an extra prefix or suffix on their names by giving `configure' the
option `--program-prefix=PREFIX' or `--program-suffix=SUFFIX'.
Optional Features
=================
Some packages pay attention to `--enable-FEATURE' options to
`configure', where FEATURE indicates an optional part of the package.
They may also pay attention to `--with-PACKAGE' options, where PACKAGE
is something like `gnu-as' or `x' (for the X Window System). The
`README' should mention any `--enable-' and `--with-' options that the
package recognizes.
For packages that use the X Window System, `configure' can usually
find the X include and library files automatically, but if it doesn't,
you can use the `configure' options `--x-includes=DIR' and
`--x-libraries=DIR' to specify their locations.
Specifying the System Type
==========================
There may be some features `configure' cannot figure out automatically,
but needs to determine by the type of machine the package will run on.
Usually, assuming the package is built to be run on the _same_
architectures, `configure' can figure that out, but if it prints a
message saying it cannot guess the machine type, give it the
`--build=TYPE' option. TYPE can either be a short name for the system
type, such as `sun4', or a canonical name which has the form:
CPU-COMPANY-SYSTEM
where SYSTEM can have one of these forms:
OS KERNEL-OS
See the file `config.sub' for the possible values of each field. If
`config.sub' isn't included in this package, then this package doesn't
need to know the machine type.
If you are _building_ compiler tools for cross-compiling, you should
use the option `--target=TYPE' to select the type of system they will
produce code for.
If you want to _use_ a cross compiler, that generates code for a
platform different from the build platform, you should specify the
"host" platform (i.e., that on which the generated programs will
eventually be run) with `--host=TYPE'.
Sharing Defaults
================
If you want to set default values for `configure' scripts to share, you
can create a site shell script called `config.site' that gives default
values for variables like `CC', `cache_file', and `prefix'.
`configure' looks for `PREFIX/share/config.site' if it exists, then
`PREFIX/etc/config.site' if it exists. Or, you can set the
`CONFIG_SITE' environment variable to the location of the site script.
A warning: not all `configure' scripts look for a site script.
Defining Variables
==================
Variables not defined in a site shell script can be set in the
environment passed to `configure'. However, some packages may run
configure again during the build, and the customized values of these
variables may be lost. In order to avoid this problem, you should set
them in the `configure' command line, using `VAR=value'. For example:
./configure CC=/usr/local2/bin/gcc
causes the specified `gcc' to be used as the C compiler (unless it is
overridden in the site shell script).
Unfortunately, this technique does not work for `CONFIG_SHELL' due to
an Autoconf bug. Until the bug is fixed you can use this workaround:
CONFIG_SHELL=/bin/bash /bin/bash ./configure CONFIG_SHELL=/bin/bash
`configure' Invocation
======================
`configure' recognizes the following options to control how it operates.
`--help'
`-h'
Print a summary of the options to `configure', and exit.
`--version'
`-V'
Print the version of Autoconf used to generate the `configure'
script, and exit.
`--cache-file=FILE'
Enable the cache: use and save the results of the tests in FILE,
traditionally `config.cache'. FILE defaults to `/dev/null' to
disable caching.
`--config-cache'
`-C'
Alias for `--cache-file=config.cache'.
`--quiet'
`--silent'
`-q'
Do not print messages saying which checks are being made. To
suppress all normal output, redirect it to `/dev/null' (any error
messages will still be shown).
`--srcdir=DIR'
Look for the package's source code in directory DIR. Usually
`configure' can determine that directory automatically.
`configure' also accepts some other, not widely useful, options. Run
`configure --help' for more details.

This libburnia.pykix.org toplevel README (C) 2006-2007 Thomas Schmitt
------------------------------------------------------------------------------
Build and Installation
Our build system is based on autotools. For preparing the build of a SVN
snapshot you will need autotools of at least version 1.7.
Check out from SVN by
svn co http://libburnia-svn.pykix.org/libburn/trunk libburn_pykix
go into directory libburn_pykix and apply autotools by
./bootstrap
Alternatively you may unpack a release tarball for which you do not need
autotools installed.
To build a libburnia.pykix.org subproject it should be sufficient to go
into its toplevel directory (here: "libburn_pykix") and execute
./configure
make
To make the libraries accessible for running resp. developing applications
make install
The other half of the project, libisofs, is hosted in the libburnia SVN, too:
svn co http://libburnia-svn.pykix.org/libisofs/trunk libisofs_pykix
See README file there.
------------------------------------------------------------------------------
Overview of libburnia.pykix.org
libburnia.pykix.org is an open-source software project for reading, mastering
and writing optical discs.
For now this means only CD media and all single layer DVD media except DVD+R.
The project comprises of several more or less interdependent parts which
together strive to be a usable foundation for application development.
These are libraries, language bindings, and middleware binaries which emulate
classical (and valuable) Linux tools.
Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
we would need : login on a development machine resp. a live OS on CD or DVD,
advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
volunteers for testing of realistic use cases.
We have a workable code base for burning CD and most single layer DVD.
The burn API is quite comprehensively documented and can be used to build a
presentable application.
We have a functional binary which emulates parts of cdrecord in order to
prove that usability, and in order to allow you to explore libburnia's scope
by help of existing cdrecord frontends.
The project components (list subject to growth, hopefully):
- libburn is the library by which preformatted data get onto optical media.
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
/dev/hdX (e.g. on kernel 2.6).
libburn is the foundation of our cdrecord emulation. Its code is
independent of cdrecord. Its DVD capabilities are learned from
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
- libisofs is the library to pack up hard disk files and directories into a
ISO 9660 disk image. This may then be brought to media via libburn.
libisofs is to be the foundation of our upcoming mkisofs emulation.
- cdrskin is a limited cdrecord compatibility wrapper for libburn.
Cdrecord is a powerful GPL'ed burn program included in Joerg
Schilling's cdrtools. cdrskin strives to be a second source for
the services traditionally provided by cdrecord. Additionally it
provides libburn's DVD capabilities, where only -sao is compatible
with cdrecord.
cdrskin does not contain any bytes copied from cdrecord's sources.
Many bytes have been copied from the message output of cdrecord
runs, though.
See cdrskin/README and man cdrskin/cdrskin.1 for more.
- test is a collection of application gestures and examples given by the
authors of the library features. The main API example for libburn
is test/libburner.c .
Explore these examples if you look for inspiration.
We plan to be a responsive upstream. Bear with us. We are still practicing.
------------------------------------------------------------------------------
Project history as far as known to me:
- Founded in 2002 as it seems. See mailing list archives
http://lists.freedesktop.org/archives/libburn/
The site of this founder team is reachable and offers download of a
(somewhat outdated) tarball and from CVS :
http://icculus.org/burn/
Copyright holders and most probably founders:
Derek Foreman and Ben Jansens.
- I came to using libburn in 2005. Founded the cdrskin project and submitted
necessary patches which were accepted or implemented better. Except one
remaining patch which prevented cdrskin from using vanilla libburn from CVS.
The cdrskin project site is reachable and offers download of the heavily
patched (elsewise outdated) tarball under the name cdrskin-0.1.2 :
http://scdbackup.sourceforge.net/cdrskin_eng.html
It has meanwhile moved to use vanilla libburn.pykix.org , though.
Version 0.1.4 constitutes the first release of this kind.
- In Juli 2006 our team mate Mario Danic announced a revival of libburn
which by about nearly everybody else was perceived as unfriendly fork.
Derek Foreman four days later posted a message which expressed his
discontent.
The situation first caused me to publically regret it and then - after i
got the opportunity to move in with cdrskin - gave me true reason to
personally apologize to Derek Foreman, Ben Jansens and the contibutors at
icculus.org/burn. Posted to both projects:
http://lists.freedesktop.org/archives/libburn/2006-August/000446.html
http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html
- Mid August 2006 project cdrskin established a branch office in
libburn.pykix.org so that all maintainers of our tools have one single place
to get the current (at least slightely) usable coordinated versions of
everything.
Project cdrskin will live forth independendly for a while but it is committed
to stay in sync with libburn.pykix.org (or some successor, if ever).
cdrskin is also committed to support icculus.org/burn if the pending fork
is made reality by content changes in that project. It will cease to maintain
a patched version of icculus.org/burn though. Precondition for a new
release of cdrskin on base of icculus.org/burn would be the pending
"whitelist patch" therefore.
I would rather prefer if both projects find consense and merge, or at least
cooperate. I have not given up hope totally, yet.
I, personally, will honor any approach.
- 2nd September 2006 the decision is made to strive for a consolidation of
copyright and a commitment to GPL in a reasonable and open minded way.
This is to avoid long term problems with code of unknown origin and
with finding consense among the not so clearly defined group of copyright
claimers and -holders.
libisofs is already claimed sole copyright Mario Danic.
cdrskin and libburner are already claimed sole copyright Thomas Schmitt.
Rewrites of other components will follow and concluded by claiming full
copyright within the group of libburn.pykix.org-copyright holders.
- 16th September 2006 feature freeze for release of libburn-0.2.2 .
- 20th September 2006 release of libburn-0.2.2 .
- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .
This version of cdrskin is much more cdrecord compatible in repect
to drive addressing and audio features.
- 30th October 2006 release of cdrskin-0.2.4 .
- 13th November 2006 splitting releases of libburn+cdrskin from libisofs.
- 24th November 2006 release of libburn-0.2.6 and cdrskin-0.2.6 . cdrskin has
become suitable for unaware frontends as long as they perform only the core
of cdrecord use cases (including open-ended input streams, audio, and
multi-session).
- 28th November 2006 the umbrella project which encloses both, libisofs and
libburn, is now called libburnia. For the origin of this name, see
http://en.wikipedia.org/wiki/Liburnians .
- 16th January 2007 release of libburn-0.3.0 and cdrskin-0.3.0 . Now the scope
is widened to a first class of DVD media: overwriteable single layer types
DVD-RAM, DVD+RW, DVD-RW. This is not a cdrecord emulation but rather inspired
by dvd+rw-tools' "poor man" writing facility for this class of media.
Taking a bow towards Andy Polyakov.
- 11th February 2007 version 0.3.2 covers sequential DVD-RW and DVD-R with
multi-session and with DAO.
- 12th March 2007 version 0.3.4 supports DVD+R and thus covers all single layer
DVD media. Code for double layer DVD+/-R is implemented but awaits a tester
yet.

Clarification in my name and in the name of Mario Danic, upcoming copyright
holders on toplevel of libburnia. To be fully in effect after the remaining
other copyrighted code has been replaced by ours and by copyright-free
contributions of our friends:
------------------------------------------------------------------------------
We, the copyright holders, agree on the interpretation that
dynamical linking of our libraries constitutes "use of" and
not "derivation from" our work in the sense of GPL, provided
those libraries are compiled from our unaltered code.
Thus you may link our libraries dynamically with applications
which are not under GPL. You may distribute our libraries and
application tools in binary form, if you fulfill the usual
condition of GPL to offer a copy of the source code -altered
or unaltered- under GPL.
We ask you politely to use our work in open source spirit
and with the due reference to the entire open source community.
If there should really arise the case where above clarification
does not suffice to fulfill a clear and neat request in open source
spirit that would otherwise be declined for mere formal reasons,
only in that case we will duely consider to issue a special license
covering only that special case.
It is the open source idea of responsible freedom which will be
decisive and you will have to prove that you exhausted all own
means to qualify for GPL.
For now we are firmly committed to maintain one single license: GPL.

cdrskin. By Thomas Schmitt <scdbackup@gmx.net>
Integrated sub project of libburnia.pykix.org but also published via:
http://scdbackup.sourceforge.net/cdrskin_eng.html
http://scdbackup.sourceforge.net/cdrskin-0.3.5.tar.gz
Copyright (C) 2006-2007 Thomas Schmitt
------------------------------------------------------------------------------
On top of libburn there is implemented cdrskin 0.3.5, a limited cdrecord
compatibility wrapper which allows to use some libburn features from
the command line.
Interested users of cdrecord are invited to participate in the development
of cdrskin. Contact: scdbackup@gmx.net or libburn-hackers@pykix.org .
We will keep copyright narrow but will of course acknowledge valuable
contributions in a due way.
Important :
This software is provided as is. There is no warranty implied and no
protection against possible damages. You use this on your own risk.
Don't blame me or other authors of libburn if anything goes wrong.
I used it on my own risk with :
SuSE 7.2, kernel 2.4.4, ide-scsi emulation, LITE-ON LTR48125S CD burner, 2002
SuSE 9.0, kernel 2.4.21, ide-scsi emulation, LG GSA-4082B CD/DVD burner, 2004
NEC ND-4570A CD/DVD burner, 2006
RIP-14.4, kernel 2.6.14, no ide-scsi, with all above burners
It fails to compile or run on SuSE 6.4 (kernel 2.2.14).
It does not find the IDE CD burner on SuSE 7.2 without ide-scsi.
Other people sucessfully tested cdrskin on several kernel 2.6 based x86 Linux
systems, including 64 bit systems. (Further reports are welcome.)
Compilation, First Glimpse, Installation
Obtain cdrskin-0.3.5.tar.gz, take it to a directory of your choice and do:
tar xzf cdrskin-0.3.5.tar.gz
cd cdrskin-0.3.5
Or obtain a libburnia.pykix.org SVN snapshot,
go into the toplevel directory of the snapshot (e.g. cd libburn_pykix ),
and execute the autotools script ./bootstrap . Use autools version >= 1.7 .
Within that toplevel directory of either cdrskin-0.3.5 or libburn then execute:
./configure
make
(Note: there are next-level directories "libburn" and "cdrskin". Those
would be the wrong ones. Meant is the highest directory of tarball resp.
SVN download. Among others containing files "AUTHORS", "configure",
"Makefile.am", as well as directories "libburn" and "cdrskin".)
This will already produce a cdrskin binary. But it might be necessary to
install libburn in order to use this binary. Installation of libburn is
beyond the scope of cdrskin. For this, see included libburn docs.
In order to surely get a standalone binary, execute
cdrskin/compile_cdrskin.sh
Version identification and help texts available afterwards:
cdrskin/cdrskin -version
cdrskin/cdrskin --help
cdrskin/cdrskin -help
man cdrskin/cdrskin.1
Install (eventually as superuser) cdrskin to a directory where it can be found:
If cdrskin was already installed by a previous version, or by "make install"
in the course of this installation, then find out where:
which cdrskin
Copy your standalone binary to exactly the address which you get as reply
cp cdrskin/cdrskin /usr/bin/cdrskin
Check the version timestamps of the globally installed binary
cdrskin -version
It is not necessary for the standalone cdrskin binary to have libburn
installed, since it incorporates the necessary libburn parts at compile time.
It will not collide with an installed version of libburn either.
But libpthread must be installed on the system and glibc has to match. (See
below for a way to create a statically linked binary.)
To install the man page, you may do: echo $MANPATH and choose one of the
listed directories to copy the man-page under its ./man1 directory. Like:
cp cdrskin/cdrskin.1 /usr/share/man/man1/cdrskin.1
Usage
The user of cdrskin needs rw-permission for the CD burner device.
A list of rw-accessible drives can be obtained by
cdrskin --devices
CD devices which offer no rw-permission are invisible to normal users.
The superuser should be able to see any usable drive and then set the
permissions as needed. If this hangs then there is a drive with
unexpected problems (locked, busy, broken, whatever). You might have to
guess the address of your (non-broken) burner by other means, then.
On Linux 2.4 this would be some /dev/sgN and on 2.6. some /dev/hdX.
The output of cdrskin --devices might look like
0 dev='/dev/sg0' rwrwr- : '_NEC' 'DVD_RW ND-4570A'
1 dev='/dev/sg1' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B'
So full and insecure enabling of both for everybody would look like
chmod a+rw /dev/sg0 /dev/sg1
I strongly discourage to run cdrskin with setuid root or via sudo !
It is not checked for the necessary degree of hacker safety.
Usage examples
For options and recordable media classes see
man 1 cdrskin
Get an overview of cdrecord style addresses of available devices
cdrskin -scanbus
cdrskin dev=ATA -scanbus
cdrskin --devices
Adresses reported with dev=ATA need prefix "ATA:". Address examples:
dev=0,1,0 dev=ATA:1,0,0 dev=/dev/sg1 dev=/dev/hdc
See also "Drive Addressing" below.
Obtain some info about the drive
cdrskin dev=0,1,0 -checkdrive
Obtain some info about the drive and the inserted media
cdrskin dev=0,1,0 -atip -v
Make used CD-RW or used unformatted DVD-RW writeable again
cdrskin -v dev=0,1,0 blank=fast -eject
Format DVD-RW to avoid need for blanking before re-use
cdrskin -v dev=0,1,0 blank=format_overwrite
De-format DVD-RW to make it capable of multi-session again
cdrskin -v dev=/dev/sr0 blank=deformat_sequential
Burn image file my_image.iso to media
cdrskin -v dev=0,1,0 speed=12 fs=8m driveropts=burnfree padsize=300k \
-eject my_image.iso
Write multi-session to the same CD , DVD-R[W] or DVD+R
cdrskin dev=/dev/hdc padsize=300k -multi 1.iso
cdrskin dev=/dev/hdc padsize=300k -multi -tao 2.iso
cdrskin dev=/dev/hdc padsize=300k -multi -tao 3.iso
cdrskin dev=/dev/hdc padsize=300k -tao 4.iso
Get multi-session info for option -C of program mkisofs:
c_values=$(cdrskin dev=/dev/hdc -msinfo 2>/dev/null)
mkisofs ... -C "$c_values" ...
Burn a compressed afio archive to media on-the-fly
find . | afio -oZ - | cdrskin -v dev=0,1,0 fs=32m speed=8 -tao \
driveropts=burnfree padsize=300k -
Burn 6 audio tracks from files with different formats to CD (not to any DVD).
Anything except .wav or .au files has to be converted into raw format first.
See below "Audio CD" for specifications.
ogg123 -d raw -f track01.cd /path/to/track1.ogg
oggdec -R -o track02.cd /path/to/track2.ogg
lame --decode -t /path/to/track3.mp3 track03.cd
madplay -o raw:track04.cd /path/to/track4.mp3
mppdec --raw-le /path/to/track5.mpc track05.cd
cdrskin -v dev=0,1,0 blank=fast -eject speed=48 -sao \
-audio -swab track0[1-5].cd /path/to/track6.wav
Usage example with http://scdbackup.sourceforge.net
Address may be a cdrecord-style "scsibus,target,lun" as listed with
cdrskin -scanbus (and hopefully as listed with cdrecord -scanbus) :
export SCDBACKUP_SCSI_ADR="0,1,0"
or a device file address as listed by --devices with an accessible drive :
export SCDBACKUP_SCSI_ADR="/dev/sg1"
Set usage of cdrskin with appropriate options rather than cdrecord :
export SCDBACKUP_CDRECORD="cdrskin -v -v"
Run a backup :
scdbackup_home
Restrictions
Many cdrecord options are still unsupported.
If you have use cases for them, please report your wishes and expectations.
DVD support is restricted to single layer DVD for now. Double layer media
are implemented but untested.
Inspiration and Standard
For the original meaning of cdrecord options see :
man cdrecord
(http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html)
Do not bother Joerg Schilling with any cdrskin problems.
(Be cursed if you install cdrskin as "cdrecord" without clearly forwarding
this "don't bother Joerg" demand.)
cdrskin does not contain any bytes copied from cdrecord's sources. Many bytes
have been copied from the message output of cdrecord runs, though. I am
thankful to Joerg Schilling for every single one of them.
I have the hope that Joerg feels more flattered than annoyed by cdrskin.
Many thanks to Andy Polyakov for his dvd+rw-tools
http://fy.chalmers.se/~appro/linux/DVD+RW/tools
which provide me with examples and pointers into MMC specs for DVD writing.
Drive Addressing
Drives get addressed either via their cdrecord-style addresses as listed
with option -scanbus (see below "Pseudo-SCSI Adresses") or via the paths
of device files.
Not only device files listed by --devices may be used but also device files
which via their major,minor numbers point to the same device driver as
a listed device file.
Helpful with Linux kernel 2.4 is a special SCSI feature:
It is possible to address a scsi(-emulated) drive via associated device files
which are not listed by option --devices but point to the same SCSI addresses
as listed device files. This addressing via e.g. /dev/sr0 or /dev/scd1 is
compatible with generic read programs like dd and with write program growisofs.
Pseudo-SCSI Adresses
cdrecord and cdrskin share the syntax of SCSI addresses but not necessarily
the meaning of the components. A cdrecord-style address for cdrskin
[prefix:]scsibus,target,lun
can be interpreted in two different modes.
Standard mode tries to be compatible to original cdrecord. This should be true
with (emulated) SCSI where the /dev/sgN with is looked up with matching
scsibus,target,lun as given by the operating system.
With dev=ATA: or dev=ATAPI: the translation to /dev/hdX is purely literal
but matches the cdrecord addresses on all systems tested so far:
X = 'a' + 2 * scsibus + target
where target only may have the values 0 or 1.
In this mode, option -scanbus will list only SCSI devices unless option
dev=ATA or dev=ATAPI are given, which will suppress SCSI devices and only
show IDE drives (i.e. /dev/hdX without ide-scsi emulation).
In mode --old_pseudo_scsi_adr there is a scsibus,target,lun representation
which has nothing to do with SCSI and thus is not compatible to cdrecord.
Each number triple corresponds either to a device file address or to a
libburn drive number.
Component "scsibus" indicates the translation method. Defined busses are:
0 target is the libburn drivenumber as listed with --devices
1 associated to device file /dev/sgN , target chooses N
2 associated to device file /dev/hdX , target 0='a', 1='b' ..., 25='z'
So "1,1,0" is /dev/sg1, "2,3,0" is /dev/hdd, "0,2,0" is libburn drive #2 at
some unspecified device file.
This scheme shall help to keep cdrecord-style addresses stable and exchangeable
between users without excluding drives with unexpected device addresses.
The numbering on bus 0 is prone to arbitrary changes caused by changes in
drive accessability.
Further busses may emerge as libburn evolves. "prefix" and "lun" may get
a meaning. To stay upward compatible, use addresses as printed by -scanbus.
User Defined Device Address Translation
Some programs or users have their own ideas about the address of their burner.
K3b 0.10 for example derives cdrecord addresses by own examination of the
devices and not by calling cdrecord -scanbus.
Standard mode will hopefully be fully compatible with their ideas.
Old frontends which do not know dev=ATA or dev=ATAPI and which do ask their
"cdrecord" via -scanbus may be well served with option --old_pseudo_scsi_adr .
To direct any remaining stubborn callers to the appropriate drives, cdrskin
allows to define device address aliases. Like
cdrskin dev_translation=+1,0,0+/dev/sg1 \
dev_translation=+ATA:1,0,0+/dev/sg1 \
dev_translation=-"cd+dvd"-0,1,0 \
...
Any of the addresses dev=1,0,0, dev=ATA:1,0,0, dev=cd+dvd will be mapped to
/dev/sg1 resp. to 0,1,0.
The first character after "dev_translation=" defines the character which
separates the two parts of the translation pair. (Above: "+" and "-".)
In K3b 0.10 it is possible to employ alternative writer programs by setting
their full path (e.g. /usr/bin/cdrskin) in menu
Settings:Configure K3b...:Programs:Search Path
and to make them default in menu
Settings:Configure K3b...:Programs:Programs:
A suitable setting for "cdrecord" in menu
Settings:Configure K3b...:Programs:User Parameters
would then probably be
-v dev_translation=+1,0,0+/dev/sg1
You will learn from button "Show Debugging Output" after a failed burn run
what cdrecord command was used with what address "dev=...". This address "..."
will be the right one to replace "1,0,0" in above example.
Startup Files
If not --no_rc is the first argument then cdrskin attempts on startup to read
arguments from the following three files:
/etc/default/cdrskin
/etc/opt/cdrskin/rc
/etc/cdrskin/cdrskin.conf
$HOME/.cdrskinrc
The files are read in the sequence given above.
Each readable line is treated as one single argument. No extra blanks.
A first character '#' marks a comment, empty lines are ignored.
Example content of a startup file:
# This is the default device
dev=0,1,0
# To accomodate to eventual remnant cdrskin-0.2.2 addresses

Audio CD
Lorenzo Taylor enabled option -audio in cdrskin (thanks !) and reports neat
results with audio data files which are :
headerless PCM (i.e. uncompressed)
44100 Hz sampling rate
16 bits per sample
stereo (2 channels)
little-endian byte order with option -swab, or big-endian without -swab
Files with name extension .wav get examined wether they are in Microsoft WAVE
format with above parameters and eventually get extracted by cdrskin itself.
In the same way files with name extension .au get examined wether they are
in SUN's audio format. For both formats, track format -audio and eventual
endianness option -swab are enabled automatically.
Any other formats are to be converted to format .wav with above parameters
or to be extracted as raw CD track data by commands like those given above
under "Usage examples". Those raw files need option -audio and in most cases
option -swab to mark them as little-endian/Intel/LSB-first 16-bit data.
Incorrect endianness setting results in random noise on CD.
I myself am not into audio. So libburn-hackers@pykix.org might be the
best address for suggestions, requests and bug reports.
DVD+RW and DVD-RAM
DVD+RW and DVD-RAM media get treated as blank media regardless wether they
hold data or not. Options -audio and -multi are not allowed. Only one track
is allowed. -toc does not return information about the media content.
Speed is counted in DVD units (i.e. 1x = 1,385,000 bytes/second). Currently
there is no difference between -sao and -tao. If ever, then -tao will be the
mode which preserves the current behavior.
For these media, -msinfo alone would not be enough to perform appending of an
ISO filesystem. The filesystem driver will need a hint to find the start of the
most recent session. For example put an ISO filesystem at address 1 GB:
mkisofs -C 0,524288 ... | \
cdrskin dev=/dev/sr0 -v fs=32m -eject speed=4 write_start_address=524288s -
The superuser may then do:
mount -t iso9660 -o ro,sbsector=524288 /dev/sr0 /mnt
Note: On my linux-2.4.21-215 mount works only with sbsector <= 337920 (660 MB).
To extend a filesystem already existing at address 0
mkisofs -C 0,524288 -M /dev/sr0 ... | cdrskin dev=/dev/sr0 ...
Record the number 524288 for usage as first number with -C at the next
extension:
mkisofs -C 524288,1000000 ... | cdrskin write_start_address=1000000s ...
Program growisofs can append to an ISO filesystem on DVD+RW by additionally
manipulating the first session. cdrskin does not want to get involved so deep
into the format of the burned data. Be advised to use growisofs for the
task of maintaining extendable ISO-Filesystems on DVD+RW.
DVD-RW and DVD-R
DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
"Sequential Recording". DVD-R are always in sequential state.
"Sequential" is the state of unused media and of media previously blanked
or written by cdrecord. dvd+rw-format -blank can also achieve this state.
The according cdrskin option is blank=deformat_sequential .
If "Incremental Streaming" is available, then sequential media are capable
of multi-session like CD-R[W]. (But not capable of -audio recording.)
This means they need option -multi to stay appendable, need to be blanked
to be writeable from start, return useable info with -toc and -msinfo,
eventually perform appending automatically.
Without "Incremental Streaming" offered by the drive, only write mode DAO is
available with sequential DVD-R[W]. It only works with blank media, allows only
one single track, no -multi, and demands a fixely predicted track size.
(growisofs uses it with DVD-R[W] if option -dvd-compat is given.)
Overwriteable DVD-RW behave much like DVD+RW. "Restricted" refers only to the
granularity of random access and block size which have always to be aligned to
full 32 kB. Sequential DVD-RW are converted into overwriteable DVD-RW by
cdrskin dev=... -v blank=format_overwrite
(Command dvd+rw-format -force can achieve "Restricted Overwrite", too.)
Formatting or first use of freshly formatted DVD-RW can produce unusual noises
from the drive and last several minutes. Depending on mutual compatibility of
drive and media, formatting can yield unusable media. It seems that those die
too on blanking by cdrecord, dvd+rw-format or cdrskin. Perils of DVD-RW.
There are three DVD-RW formatting variants with cdrskin currently:
blank=format_overwrite uses "DVD-RW Quick" formatting (MMC-type 15h)
and writes a first session of 128 MB. This leads to media which are expandable
and random addressable by cdrskin.
blank=format_overwrite_quickest uses "DVD-RW Quick" formatting (type 15h) too,
but leaves the media in "intermediate" state. In the first session of writing
one may only write sequentially to such a DVD. After that, it gets random
addressable by cdrskin. DVD-ROM drives might show ill behavior with them.
blank=format_overwrite_full uses preferrably "Full Format" (type 00h).
This formatting lasts as long as writing a full DVD. It includes writing of
lead-out which is said to be good for DVD ROM compatibility.
De-formatting options are available to make overwriteable DVD-RW sequential:
blank=deformat_sequential performs thorough blanking of all states of DVD-RW.
blank=all and blank=fast perform the same thorough blanking, but refuse to do
this with overwriteable DVD-RW, thus preserving their formatting. The specs
allow minimal blanking but the resulting media on my drives offer no
Incremental Streaming afterwards. So blank=fast will do full blanking.
blank=deformat_sequential_quickest is faster but might yield DAO-only media.
DVD+R
From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
into an own session, though.
------------------------------------------------------------------------------
Special compilation variations
You may get a (super fat) statically linked binary by :
cdrskin/compile_cdrskin.sh -static
if your system supports static linking, at all. This will not help with kernels
which do not properly support the necessary low-level interfaces chosen by
your compile-time libraries.
A size reduced but fully functional binary may be produced by
cdrskin/compile_cdrskin.sh -do_strip
An extra lean binary with reduced capabilities is created by
cdrskin/compile_cdrskin.sh -do_diet -do_strip
It will not read startup files, will abort on option dev_translation= ,
will not have a fifo buffer, and will not be able to put out help texts or
debugging messages.

cdrskin is currently copyright Thomas Schmitt only.
It adopts the following commitment by the toplevel copyright holders:
------------------------------------------------------------------------------
We, the copyright holders, agree on the interpretation that
dynamical linking of our libraries constitutes "use of" and
not "derivation from" our work in the sense of GPL, provided
those libraries are compiled from our unaltered code.
Thus you may link our libraries dynamically with applications
which are not under GPL. You may distribute our libraries and
application tools in binary form, if you fulfill the usual
condition of GPL to offer a copy of the source code -altered
or unaltered- under GPL.
We ask you politely to use our work in open source spirit
and with the due reference to the entire open source community.
If there should really arise the case where above clarification
does not suffice to fulfill a clear and neat request in open source
spirit that would otherwise be declined for mere formal reasons,
only in that case we will duely consider to issue a special license
covering only that special case.
It is the open source idea of responsible freedom which will be
decisive and you will have to prove that you exhausted all own
means to qualify for GPL.
For now we are firmly committed to maintain one single license: GPL.

.PP
\fBcdrskin\fP is a program that provides some of cdrecord's options
in a compatible way for CD media. With DVD it has its own ways.
You do not need to be superuser for its daily usage.
.PP
.B Overview of features:
.br
Blanking of CD-RW and DVD-RW.
.br
Burning of data or audio tracks to CD,
.br
either in versatile Track at Once mode (TAO)
.br
or in Session at Once mode for seamless tracks.
.br
Multi session on CD (follow-up sessions in TAO only)
.br
or on DVD-R[W] (in Incremental mode) or on DVD+R.
.br
Single session on DVD-RW or DVD-R (Disk-at-once)
.br
or on overwriteable DVD+RW, DVD-RW, DVD-RAM.
.br
Bus scan, burnfree, speed options, retrieving media info, padding, fifo.
.br
See section EXAMPLES at the end of this text.
.PP
.B General information paragraphs:
.br
Track recording model
.br
Write mode selection
.br
Recordable CD Media
.br
Sequentially Recordable DVD Media
.br
Overwriteable DVD Media
.br
Drive preparation and addressing
.PP
.B Track recording model:
.br
The input-output entities which get processed are called tracks.
A \fBtrack\fP stores a stream of bytes.
.br
Each track is initiated by one track source address argument, which may either
be "-" for standard input or the address of a readable file. If no write mode
is given explicitely then one will be chosen which matches the peculiarities
of track sources and the state of the output media.
.PP
More than one track can be burned by a single run of cdrskin.
In the terms of the MMC standard all tracks written by the same run constitute
a \fBsession\fP.
.br
Some media types can be kept appendable so that further tracks can
be written to them in subsequent runs of cdrskin (see option -multi).
Info about the addresses of burned tracks is kept in a table of
content (TOC) on media and can be retrieved via cdrskin option -toc.
These informations are also used by the operating systems' CD-ROM read drivers.
.PP
In general there are two types of tracks: data and audio. They differ in
sector size, throughput and readability via the systems' CD-ROM drivers
resp. by music CD players. With DVD there is only type data.
.br
If not explicitely option -audio is given, then any track is burned as type
data, unless the track source is a file with suffix ".wav" or ".au" and has a
header part which identifies it as MS-WAVE resp. SUN Audio with suitable
parameters. Such files are burned as audio tracks by default.
.PP
While audio tracks just contain a given time span of acoustic vibrations,
data tracks may have an arbitray meaning. Nevertheless, ISO-9660 filesystems
are established as a format which can represent a tree of directories and
files on all major operating systems. Such filesystem images can be
produced by programs mkisofs or genisoimage. They can also be extended by
follow-up tracks if prepared properly. See the man pages of said programs.
cdrskin is able to fulfill the needs about their option -C.
.br
Another type of data track content are archive formats which originally
have been developed for magnetic tapes. Only formats which mark a detectable
end-of-archive in their data are suitable, though. Well tested are
the archivers afio and star. Not suitable seems GNU tar.
.PP
.B Write mode selection:
.br
If none of the options -dao, -tao or -sao is given then the program will
try to choose a write mode which matches the defined recording job,
the capabilities of the drive and the state of the present media.
.br
So the mentioning of write modes in the following paragraphs and in the
examples is not so much a demand that the user shall choose one explicitely,
but rather an illustration of what to expect with particular media types.
.PP
.B Recordable CD Media:
.br
CD-R can be initially written only once and eventually extended until they
get closed (or are spoiled because they are overly full). After that they are
read-only. Closing is done automatically unless option
.B -multi
is given which keeps the media appendable.
.br
There are two write modes,
.B -tao
and
.B -sao .
.br
-tao allows to use track source of unpredictable length (like stdin) and allows
to write further sessions to appendable media. -sao produces audio sessions
with seamless tracks but needs predicted track sizes and cannot append sessions
to media.
.br
CD-RW media can be blanked to make them re-usable for another
round of overwriting. Usually
.B blank=fast
is the appropriate option.
Blanking damages the previous content but does not
make it completely unreadable. It is no effective privacy precaution.
Multiple cycles of blanking and overwriting with random numbers might be.
.PP
.B Sequentially Recordable DVD Media:
.br
Currently DVD-RW, DVD-R and DVD+R can be used for the Sequential recording
model.
.br
DVD-RW must be in state "Sequential Recording".
The media must be either blank or appendable.
Newly purchased DVD-RW and DVD-R media are in this state.
Used DVD-RW get into blank sequential state by option
.B blank=deformat_sequential .
.br
With DVD-R[W] two write modes may be available:
.br
Mode DAO has many restrictions. It does not work with
appendable media, allows no -multi and only a single track. The size of the
track needs to be known in advance. So either its source has to be a disk file
of recognizable size or the size has to be announced explicitely by options
.B tsize=
or
.B tao_to_sao_tsize= .
.br
DAO is the only mode for media which do not offer feature 21h Incremental
Streaming. DAO may also be selected explicitely by option
.B -sao .
Program growisofs uses DAO on sequential DVD-R[W] media for maximum
DVD-ROM/-Video compatibility.
.br
The other mode, Incremental Streaming, is the default write mode if
it is available and if the restrictions of DAO would prevent the job.
Incremental Streaming may be selected explicitely by option
.B -tao
as it resembles much CD TAO by allowing track sources of
unpredicted length and to keep media appendable by option
.B -multi .
The only restriction towards CD-R[W] is the lack of support for -audio tracks.
Multiple tracks per session are permissible.
.br
The write modes for DVD+R resemble those with DVD-R except that with DVD+R
each track gets wrapped in an own session. There is no -dummy writing with
DVD+R.
.br
Quite deliberately write mode -sao insists in the tradition of a predicted
track size and blank media, whereas -tao writes the tracks open ended and
allows appendable media.
.PP
.B Overwriteable DVD Media:
.br
Currently types DVD+RW, DVD-RW and DVD-RAM can be overwritten via cdrskin.
.br
DVD+RW and DVD-RAM media get treated as blank media regardless wether they
hold data or not. They need no special initial formatting.
Options -audio and -multi are not allowed. Only one track is allowed.
-toc does not return information about the media content.
Currently there is no difference between -sao and -tao. If ever, then -tao
will be the mode which preserves the current behavior.
.br
DVD-RW are sold in state "Sequential Recording". To become suitable for the
Overwriteable DVD recording model they need to get formatted to state
"Restricted Overwrite". Then they behave much like DVD+RW. This formatting
can be done by option
.B blank=format_overwrite .
.br
Several programs like dvd+rw-format, cdrecord, wodim, or cdrskin
can bring a DVD-RW out of overwriteable state so
that it has to be formatted again. If in doubt, just give it a try.
.PP
.B Drive preparation and addressing:
.br
The drives, either CD burners or DVD burners, are accessed via addresses which
are specific to libburn and the operating system. Those addresses get listed
by a run of \fBcdrskin --devices\fP.
.br
On Linux, they are device files which traditionally do not offer
w-permissions for normal users. Because libburn needs rw-permission,
it might be only the
.B superuser
who is able to get this list without further
precautions.
.br
It is consensus that \fBchmod a+rw /dev/sr0\fP or \fBchmod a+rw /dev/hdc\fP
is less security sensitive than chmod u+s /usr/bin/cdrskin. The risk for the
drive is somewhat higher but the overall system is much less at stake.
.br
.PP
If you only got one CD capable drive then you may leave out cdrskin option
\fBdev=\fP. Else you should use this option to address the drive you want.
.br
cdrskin option dev= not only accepts the listed addresses but also
traditional cdrecord SCSI addresses which on Linux consist of three
numbers: Bus,Target,Lun. There is also a related address family "ATA" which
accesses IDE drives not under control of Linux SCSI drivers:
ATA:Bus,Target,Lun.
.br
See option -scanbus for getting a list of cdrecord style addresses.
.br
Further are accepted on Linux: links to libburn-suitable device files,
device files which have the same major and minor device number,
and device files which have the same SCSI address parameters (e.g. /dev/sg0).
.br
.SH OPTIONS
.TP
.BI \-\-help
Show non-cdrecord compatible options.
.TP
.BI \-help
Show cdrecord compatible options.
.TP
.BI \-version
Print cdrskin id line, compatibility lure line, libburn version, cdrskin
version, version timestamp, build timestamp (if available), and then exit.
.PP
Alphabetical list of options which are intended to be compatible with
original cdrecord by Joerg Schilling:
.TP
.BI \-atip
Retrieve some info about media state. With CD-RW print "Is erasable".
With DVD media print "book type:" and a media type text.
.TP
.BI \-audio
Announces that the subsequent tracks are to be burned as audio.
The source is supposed to be uncompressed headerless PCM, 44100 Hz, 16 bit,
stereo. For little-endian byte order (which is usual on PCs) use option
-swab. Unless marked explicitely by option -data, input files with suffix
.wav are examined wether they have a header in MS-WAVE format confirming
those parameters and eventually raw audio data get extracted and burned as
audio track. Same is done for suffix .au and SUN Audio.
.br
Option -audio may be used only with CD media and not with DVD.
.TP
.BI blank= type
Blank a CD-RW, a DVD-RW, or format a DVD+/-RW.
This is combinable with burning in the same run of cdrskin.
The type given with blank= selects the particular behavior:
.RS
.TP
help
Print this list of blanking types.
.TP
all
Blank an entire CD-RW or an unformatted DVD-RW.
(See also --prodvd_cli_compatible)
.TP
fast
Minimally blank an entire CD-RW or blank an unformatted DVD-RW.
(See also --prodvd_cli_compatible)
.TP
format_overwrite
Format a DVD-RW to "Restricted Overwrite". The user should bring some patience.
.br
(Note: blank=format_overwrite* are not original cdrecord options.)
.TP
format_overwrite_quickest
Like format_overwrite without creating a 128 MB trailblazer session.
Leads to "intermediate" state which only allows sequential write
beginning from address 0.
The "intermediate" state ends after the first session of writing data.
.TP
format_overwrite_full
For DVD-RW this is like format_overwrite but claims full media size
rather than just 128 MB.
Most traditional formatting is attempted. No data get written.
Much patience is required.
.br
This option treats already formatted media even if not option -force is given.
.br
For DVD+RW this is the only supported explicit formatting type. It provides
complete "de-icing" so no reader slips on unwritten data areas.
.TP
deformat_sequential
Like blank=all but with the additional ability to blank overwriteable DVD-RW.
This will destroy their formatting and make them sequentially recordable.
Another peculiarity is the ability to blank media which appear already blank.
This is similar to option -force but does not try to blank media other than
recognizable CD-RW and DVD-RW.
.br
(Note: blank=deformat_sequential* are not original cdrecord options.)
.TP
deformat_sequential_quickest
Like blank=deformat_sequential but blanking DVD-RW only minimally.
This is faster than full blanking but may yield media incapable of
Incremental Streaming (-tao).
.RE
.TP
.BI \-checkdrive
Retrieve some info about the addressed drive.
Exits with non-zero value if the drive cannot be found and opened.
.TP
.BI \-dao
Alias for option -sao. Write CD in Session at Once mode
or DVD-R[W] in Disc-at-once mode.
.TP
.BI \-data
Subsequent tracks are data tracks. This option is default and only needed
to mark the end of the range of an eventual option -audio.
.TP
.BI dev= target
Set the address of the drive to use. Valid are at least the
addresses listed with option --devices,
X,Y,Z addresses listed with option -scanbus,
ATA:X,Y,Z addresses listed with options dev=ATA -scanbus,
and volatile libburn drive numbers (numbering starts at "0").
Other device file addresses which lead to the same drive might work too.
.br
If no dev= is given, volatile address "dev=0" is assumed. That is the first
drive found being available. Better avoid this ambiguity on systems with more
than one drive.
.br
The special target "help" lists hints about available addressing formats.
Be aware that deprecated option --old_pseudo_scsi_adr may change the meaning
of Bus,Target,Lun addresses.
.TP
.BI driveropts= opt
Set "driveropts=noburnfree" to disable the drive's eventual protection
mechanism against temporary lack of source data (i.e. buffer underrun).
A drive that announces no such capabilities will not get them enabled anyway,
even if attempted explicitely via "driveropts=burnfree".
.TP
.BI \-dummy
Try to perform the drive operations without actually affecting the inserted
media. There is no guarantee that this will work with a particular combination
of drive, media, and write mode. Blanking is prevented reliably, though.
.TP
.BI \-eject
Eject the disc after work is done.
.TP
.BI \-force
Assume that the user knows better in situations when cdrskin or libburn are
insecure about drive or media state. This includes the attempt to blank
media which are classified as unknown or unsuitable, and the attempt to use
write modes which libburn believes they are not supported by the drive.
.br
Another application is to enforce blanking or re-formatting of media
which appear to be in the desired blank or format state already.
.br
.B Caution:
Use this only when in urgent need.
.TP
.BI fs= size
Set the fifo size to the given value. The value may have appended letters which
multiply the preceding number:
.br
"k" or "K" = 1024 , "m" or "M" = 1024k , "g" or "G" = 1024m , "s" or "S" = 2048
.br
Set size to 0 in order to disable the fifo (default is "4m").
.br
The fifo buffers an eventual temporary surplus of track source data in order to
provide the drive with a steady stream during times of temporary lack of track
source supply.
The larger the fifo, the longer periods of poor source supply can be
compensated.
But a large fifo needs substantial time to fill up if not curbed via
option fifo_start_at=size.
.TP
.BI gracetime= seconds
Set the grace time before starting to write. (Default is 0)
.TP
.BI -isosize
The next track following this option will try to obtain its source size from
the header information out of the first few blocks of the source data.
If these blocks indicate an ISO-9660 filesystem then its declared size
will be used under the assumption that it is a single session filesystem.
.br
If not, then the burn run will be aborted.
.br
The range of -isosize is exactly one track. Further tracks may be preceeded
by further -isosize options, though. At least 15 blocks of padding will be
added to each -isosize track. But be advised to rather use padsize=300k.
.br
This option can be performed on track sources which are regular files or block
devices. For the first track of the session it can be performed on any type
of source if there is a fifo of at least 64 kB. See option fs= .
.TP
.BI msifile= path
Run option -msinfo and copy the result line into the file given by path.
Unlike -msinfo this option does not redirect all normal output away from
standard output. But it may be combined with -msinfo to achieve this.
.br
Note: msifile=path is actually an option of wodim and not of cdrecord.
.TP
.BI \-msinfo
Retrieve multi-session info for preparing a follow-up session by option -C
of programs mkisofs or genisoimage. Print result to standard output.
This option redirects to stderr all message output except the one of option
--tell_media_space and its own result string, which consists of two numbers.
The result string shall be used as argument of option -C with said programs.
It gives the start address of the most recent session and the predicted
start address of the next session to be appended. The string is empty if
the most recent session was not written with option -multi.
.TP
.BI \-multi
This option keeps the CD or unformatted DVD-R[W] appendable after the current
session has been written.
Without it the disc gets closed and may not be written any more - unless it
is a -RW and gets blanked which causes loss of its content.
.br
The following sessions can only be written in -tao mode. -multi is prohibited
with overwriteable DVD media and with DVD-R[W] DAO write mode.
Option --prodvd_cli_compatible eventually makes -multi tolerable but cannot
make it work.
.br
In order to have all filesystem content accessible, the eventual ISO-9660
filesystem of a follow-up
session needs to be prepared in a special way by the filesystem formatter
program. mkisofs and genisoimage expect particular info about the situation
which can be retrieved by cdrskin option -msinfo.
.br
To retrieve an archive file which was written as follow-up session,
you may use option -toc to learn about the "lba" of the desired track number.
.TP
.BI \-nopad
Do not add trailing zeros to the data stream. Nevertheless, since there seems
to be no use for audio tracks with incomplete last sector, this option applies
only to data tracks. There it is default.
.TP
.BI \-pad
Add 30 kB of trailing zeros to each data track. (This is not sufficient to
avoid problems with various CD-ROM read drivers.)
.TP
.BI padsize= size
Add the given amount of trailing zeros to the next data track. This option
gets reset to padsize=0 after that next track is written. It may be set
again before the next track argument. About size specifiers, see option fs=.
.TP
.BI \-raw96r
Write CD in RAW/RAW96R mode. This mode allows to put more payload bytes
into a CD sector but obviously at the cost of error correction. It can only
be used for tracks of fixely predicted size. Some drives allow this mode but
then behave strange or even go bad for the next few attempts to burn a CD.
One should use it only if inavoidable.
.TP
.BI \-sao
Write CD in Session At Once mode, a sequential DVD-R[W] in Disc-at-once
(DAO) mode, or a DVD+R.
.br
With CD this mode is able to put several audio tracks on media without
producing audible gaps between them.
.br
With DVD-R[W] this mode can only write a single track.
No -multi is allowed with DVD-R[W] -sao.
.br
-sao is permissible with overwriteable DVD and with DVD+R but actually only
imposes restrictions without providing known advantages.
.br
-sao can only be used for tracks of fixely predicted size. This implies that
track arguments which depict stdin or named pipes need to be preceeded by
option tsize= or by option tao_to_sao_tsize=.
.br
-sao cannot be used on appendable media.
.TP
.BI \-scanbus
Scan the system for drives. On Linux the drives at /dev/s* and at /dev/hd*
are to be scanned by two separate runs. One without dev= for /dev/s* and
one with dev=ATA for /dev/hd* devices. (Option --drives lists all available
drives in a single run.)
.br
Drives which are busy or which offer no rw-permission to the user of cdrskin
are not listed. Busy drives get reported in form of warning messages.
.br
The useful fields in a result line are:
.br
Bus,Target,Lun Number) 'Vendor' 'Mode' 'Revision'
.TP
.BI speed= number
Set speed of drive. With data CD, 1x speed corresponds to a throughput of
150,000 bytes/second. With DVD, 1x = 1,385,000 bytes/second.
It is not an error to set a speed higher than is suitable for drive
and media. One should stay within a realistic speed range, though.
.TP
.BI \-swab
Announce that the raw audio data source of subsequent tracks is byte swapped
versus the expectations of cdrecord. This option is suitable for audio where
the least significant byte of a 16 bit word is first (little-endian, Intel).
Most raw audio data on PC systems are available in this byte order.
Less guesswork is needed if track sources are in format MS-WAVE in a file with
suffix ".wav".
.TP
.BI \-tao
Write CD in Track At Once (TAO) mode, sequential DVD-R[W] in Incremental
Streaming mode, or DVD+R without traditional -sao restrictions.
This mode also applies pro-forma to overwriteable DVD media.
.br
Mode -tao can be used with track sources of unpredictable size, like standard
input or named pipes. It is also the only mode that can be used for writing
to appendable media which already hold data. With unformatted DVD-R[W] it is
the only mode which allows -multi.
.TP
.BI \-toc
Print the table of content (TOC) which describes the tracks recorded on disc.
The output contains all info from option -atip plus lines which begin with
"track:", the track number, the word "lba:" and a number which gives the
start address of the track. Addresses are counted in CD sectors which with
SAO or TAO data tracks hold 2048 bytes each.
.RS
.TP
Example. Retrieve an afio archive from track number 2:
.br
tracknumber=2
.br
lba=$(cdrskin dev=/dev/cdrom -toc 2>&1 | \\
.br
grep '^track:[ ]*[ 0-9][0-9]' | \\
.br
tail +"$tracknumber" | head -1 | \\
.br
awk '{ print $4}' )
.br
dd if=/dev/cdrom bs=2048 skip="$lba" | \\
.br
afio -t - | less
.RE
.TP
.BI tsize= size
Announces the exact size of the next track source. This is necessary with any
write mode other than -tao if the track source is not a regular disk file, but
e.g. "-" (standard input) or a named pipe.
About size specifiers, see option fs=.
.br
If the track source does not deliver the predicted amount of bytes, the
remainder of the track is padded with zeros. This is not considered an error.
If on the other hand the track source delivers more than the announced bytes
then the track on media gets truncated to the predicted size and cdrskin exits
with non-zero value.
.TP
.BI \-v
Increment verbose level by one. Startlevel is 0 with only few messages.
Level 1 prints progress report with long running operations and also causes
some extra lines to be put out with info retrieval options.
Level 2 additionally reports about option settings derived from arguments or
startup files. Level 3 is for debugging and useful mainly in conjunction with
somebody who had a look into the program sourcecode.
.PP
Alphabetical list of options which are genuine to cdrskin and intended for
normal use:
.TP
.BI \--allow_setuid
Disable the loud warning about insecure discrepance between login user and
effective user which indicates application of chmod u+s to the program binary.
One should not do this chmod u+s , but it is an old cdrecord tradition.
.TP
.BI \--any_track
Allow source_addresses to begin with "-" (plus further characters) or to
contain a "=" character.
By default such arguments are seen as misspelled options. It is nevertheless
not possible to use one of the options listed with --list_ignored_options.
.TP
.BI assert_write_lba= block_number | byte_address
Abort if the write address given with this option is not the same as predicted
immediately before the write session starts. This option can ensure that a
start address which was presumed by a formatter like mkisofs -C is really used
by the drive for writing.
assert_write_lba=0 effectively demands blank media and excludes appendables.
.br
Block numbering is peculiar: If the last character of the option string is
a letter [a-zA-Z] then the usual unit scaling by "s", "k", "m", etc. applies
and the result is divided by 2048. Else the number value of the string is
taken as plain block number with block size 2048 byte.
(E.g ...=1000 or ...=1000s means block 1000, ...=1m means block
512, ...=4096b means block number 2)
.TP
.BI \--demand_a_drive
Exit with a nonzero value if no drive can be found during a bus scan.
.TP
.BI \--devices
List the device file addresses of all accessible CD drives. In order to get
listed, a drive has to offer rw-permission for the cdrskin user and it may
not be busy. The superuser should be able to see all idle drives listed and
busy drives reported as "SORRY" messages.
.br
Each available drive gets listed by a line containing the following fields:
.br
Number dev='Devicefile' rw-Permissions : 'Vendor' 'Model'
.br
Number and Devicefile can both be used with option dev=, but number is
volatile (numbering changes if drives become busy).
.TP
.BI fifo_start_at= size
Do not wait for full fifo but start burning as soon as the given number
of bytes is read. This option may be helpful to bring the average throughput
near to the maximum throughput of a drive. A large fs= and a small
fifo_start_at= combine a quick burn start and a large savings buffer to
compensate for temporary lack of source data. At the beginning of burning,
the software protection against buffer underun is as weak as the size of
fifo_start_at= . So it is best if the drive offers hardware protection which
is enabled automatically if not driveropts=noburnfree is given.
.TP
.BI \--list_ignored_options
List all ignored cdrecord options. The "-" options cannot be used as addresses
of track sources. No track source address may begin with a text equal to an
option which ends by "=". The list is ended by an empty line.
.TP
.BI \--no_rc
Only if used as first command line argument this option prevents reading and
interpretation of eventual startup files. See section FILES below.
.TP
.BI \--prodvd_cli_compatible
Activates behavior modifications with some DVD situations which bring cdrskin
nearer to the behavior of cdrecord-ProDVD:
.br
Option -multi with unsuitable media is not an error but simply has no effect.
.br
Options blank=fast and blank=all deformat overwriteable DVD-RW media.
.br
Option blank=fast does indeed minmal blanking with DVD-RW. This may yield media
which can only do DAO but not Incremental Streaming.
.TP
.BI \--single_track
Accept only the last argument of the command line as track source address.
.TP
.BI tao_to_sao_tsize= size
Set an exact fixed size for the next track to be in effect only if the track
source cannot deliver a size prediction and no tsize= was specified and an
exact track size prediction is demanded by the write mode.
.br
This was the fallback from bad old times when cdrskin was unable to burn
in mode -tao . It came back with minimally blanked DVD-RW which allow no
Incremental Streaming (-tao) resp. with explicitly selected write mode -sao
for best DVD-ROM compatibility.
.br
If the track source delivers less bytes than announced then the missing ones
will be filled with zeros.
.TP
.BI --tell_media_space
Prepare a recording session, do not perform it but rather inquire the
maximum number of 2048 byte data blocks which may be written in
the current state of media with the prepared setup. So this option disables
recording of data. It does allow blanking, though, and will measure space
afterwards.
.br
It is not mandatory to give track sources but their nature may influence
the available capacity. So for most realistic results one may set up
the full burn session and add --tell_media_space. But if one has to expect
a cdrskin version prior to 0.3.3 no track source should be given in order
not to start an involuntary burn session.
In this case set at least -sao or -tao explicitely.
.br
The result gets printed to standard output. It is 0 or empty if no writing
is possible with the given options.
This option redirects to stderr all message output except its own result
string and eventual output of -msinfo.
.TP
.BI write_start_address= byte_offset
Set the address on media where to start writing the track. With DVD+RW or
DVD-RAM byte_offset must be aligned to 2 KB blocks, but better is 32 kB.
With DVD-RW 32 kB alignment is mandatory.
.br
Other media are not suitable for this option yet.
.PP
Alphabetical list of options which are only intended for very special
situations and not for normal use:
.TP
.BI \--abort_handler
Establish default signal handling not to leave a drive in busy state
but rather to shut it down and to wait until it has ended the final operations.
This option is only needed for revoking eventual --ignore_signals or
--no_abort_handler.
.TP
.BI \--allow_untested_media
Enable the use of media profiles which have been implemented but not yet
tested. Currently this applies to :
.br
Profile 0015h , DVD-R/DL Sequential (will not allow -multi).
.br
Profile 002Bh , DVD+R/DL.
.br
If you really test such media, then please report the outcome on
libburn-hackers@pykix.org
.TP
.BI dev_translation= <sep><from><sep><to>
Set drive address alias. This was necessary before cdrskin-0.2.4 to manually
translate cdrecord addresses into cdrskin addresses.
.br
<sep> is a single character which may not occur in the address string
<from>. <from> is an address as expected to be given by the user via option
dev=. <to> is the address to be used instead whenever <from> is given.
More than one translation instruction can be given in one cdrskin run.
.br
E.g.: dev_translation=+ATA:1,0,0+/dev/sr1 dev_translation=+ATA:1,1,0+/dev/sr2
.TP
.BI \--drive_abort_on_busy
Linux specific: Abort process if a busy drive is encountered.
.TP
.BI \--drive_blocking
Linux specific: Try to wait for a busy drive to become free.
This is not guaranteed to work with all drivers. Some need nonblocking i/o.
.TP
.BI \--drive_f_setlk
Linux specific: Try to get exclusive lock on drive device file via fcntl(2).
.TP
.BI \--drive_not_exclusive
Linux specific: Combine --drive_not_f_setlk and --drive_not_o_excl.
.TP
.BI \--drive_not_f_setlk
Linux specific: Do not try to get exclusive lock on drive device file via
fcntl(2).
.TP
.BI \--drive_not_o_excl
Linux specific: Do not ask the operating system to prevent opening busy drives.
Wether this leads to senseful behavior depends on operating system and kernel.
.TP
.BI drive_scsi_dev_family= sr | scd | sg
Linux specific: Select a SCSI device file family to be used for drive command
transactions. Normally this is /dev/sgN on kernel versions < 2.6 and /dev/srN
on kernels >= 2.6 . This option allows to explicitely override that default
in order to meet other programs at a common device file for each drive.
On kernel 2.4 families sr and scd will find no drives.
.br
Device file family /dev/hdX on kernel >= 2.6 is not affected by this setting.
.TP
.BI \--drive_scsi_exclusive
Linux specific:
Try to exclusively reserve device files /dev/srN, /dev/scdM, /dev/sgK of drives.
This would be helpful to protect against collisions with program growisofs.
Regrettably on Linux kernel 2.4 with ide-scsi emulation this seems not to
work. Wether it becomes helpful with new Linux systems has to be evaluated.
.TP
.BI \--fifo_disable
Disable fifo despite any fs=.
.TP
.BI \--fifo_per_track
Use a separate fifo for each track.
.TP
.BI \--fill_up_media
Expand the last track of the session to occupy all remaining free space on
the media.
.br
This option overrides option -multi. It will not fill up media if option -sao
is given with CD media.
.br
.B Caution:
This option might increase read compatibility with DVD-ROM drives but
with some DVD recorders and media types it might also fail to produce readable
media at all. "Your mileage may vary".
.TP
.BI grab_drive_and_wait= seconds
Open the addressed drive, wait the given number of seconds, release the drive,
and do normal work as indicated by the other options used. This option helps
to explore the program behavior when faced with busy drives. Just start a
second cdrskin with option --devices while grab_drive_and_wait= is still
active.
.TP
.BI \--ignore_signals
Try to ignore any signals rather than to abort the program. This is not a
very good idea. You might end up waiting a very long time for cdrskin
to finish.
.TP
.BI \--no_abort_handler
On signals exit even if the drive is in busy state. This is not a very good
idea. You might end up with a stuck drive that refuses to hand out the media.
.TP
.BI \--no_blank_appendable
Refuse to blank appendable CD-RW or DVD-RW. This is a feature that was once
builtin with libburn. No information available for what use case it was needed.
.TP
.BI \--no_convert_fs_adr
Do only literal translations of dev=. This prevents cdrskin from test-opening
device files in order to find one that matches the given dev= specifier.
.br
Partly Linux specific:
Such opening is needed for Bus,Target,Lun addresses unless option
--old_pseudo_scsi_adr is given. It is also needed to resolve device file
addresses which are not listed with cdrskin --devices but nevertheless point
to a usable drive. (Like /dev/sg0 using the same SCSI address as /dev/sr0.)
.TP
.BI \--old_pseudo_scsi_adr
Linux specific:
Use and report literal Bus,Target,Lun addresses rather than real SCSI and
pseudo ATA addresses. This method is outdated and was never compatible with
original cdrecord.
.br

If not --no_rc is given as the first argument then cdrskin attempts on
startup to read the arguments from the following files:
.PP
.br
.B /etc/default/cdrskin
.br
.B /etc/opt/cdrskin/rc
.br
.B /etc/cdrskin/cdrskin.conf
.br
.B $HOME/.cdrskinrc
.br
.PP
The files are read in the sequence given above, but none of them is
required for cdrskin to function properly. Each readable line is treated
as one single argument. No extra blanks.
A first character '#' marks a comment, empty lines are ignored.
.SS
.B Example content of a startup file:
.br
# This is the default device
.br
dev=0,1,0
.br
# To accomodate to remnant cdrskin-0.2.2 addresses
.br
dev_translation=+1,0,0+0,1,0

<DT>The goal is to provide some of cdrecord's options in a compatible way.
This has been achieved quite sufficiently for the needs of backup tool
<A HREF="http://scdbackup.sourceforge.net/main_eng.html">scdbackup</A>
and for data CD projects of <A HREF="http://www.k3b.org">K3b</A>
(see <A HREF="#examples">examples</A>).
Suitability for audio CD frontends has been improved much and is now being
evaluated.<BR>
Most DVD types are written in pseudo -tao modes which are very different
from the write mode DAO used by cdrecord(-ProDVD). With DVD-R[W] cdrskin
can use this write mode, too.<BR>
Further enhancements depend on people who can describe and discuss their
wishes as well as on the development of libburn.</DT>

<CENTER><H3>About the relationship of cdrecord and cdrskin</H3></CENTER>
First of all: this relationship is single sided, as cdrskin has to be aware of
cdrecord but not vice versa.
<BR>
<BR>
I am a long time user of cdrecord and it works fine for me.
Especially i do appreciate its write mode -tao which allows to pipe arbitrary
data on CD and CD-RW via stdin. cdrecord is reliable, versatile and well
maintained. So for me - there would be not problem with it.
<BR>
But the author of cdrecord and the Linux kernel people foster a very hostile
relationship. Ok, that's their business, not mine (or ours if you are with me).
One has to be aware, though, that this relationship might lead to a situation
where cdrecord is no longer available for certain Linux kernels.
<BR>
To have my own project prepared for such a time, i began to implement its
cdrecord gestures on top of libburn.
From now on i invite other interested users of cdrecord to teach cdrskin
the gestures necessary for their cdrecord applications.
Contact me. Let's see what we can achieve.
<BR>
<BR>
libburn and cdrskin are now mature enough to substitute cdrecord in its
major use cases of CD and DVD burning. It is possible to foist cdrskin on
various software packages if it gets falsely named "cdrecord".
I do not encourage this approach, but of course such a replacement
opportunity is the goal of a cdrecord compatibility wrapper.
<BR>
<BR>
It is very important to me that this project is not perceived as hostile
towards Joerg Schilling and his ongoing work.
I owe him much. For cdrecord, for mkisofs, for star. Chapeau.

'''cdrskin is the cdrecord compatibility middleware of libburn.'''
Its paragon, cdrecord, is a powerful GPL'ed burn program included in Joerg
Schilling's cdrtools. cdrskin strives to be a second source for the services
traditionally provided by cdrecord. Currently it does CD-R and CD-RW this way.
Overwriteable media DVD-RAM, DVD+RW and DVD-RW are handled differently than
with cdrecord-ProDVD in order to offer TAO-like single track recording.
Sequential DVD-R[W] and DVD+R are handled like CD-R[W] with TAO and
multi-session. Additionally cdrskin offers cdrecord-ProDVD-like mode DAO
with DVD-R[W].
cdrskin does not contain any bytes copied from cdrecord's sources.
Many bytes have been copied from the message output of cdrecord
runs, though. The most comprehensive technical overview of cdrskin
can be found in [http://libburnia.pykix.org/browser/libburn/trunk/cdrskin/README?format=txt cdrskin/README].
About libburn API for burning CD: http://libburnia-api.pykix.org
--------------------------------------------------------------------------
For dual layer DVD types and for appending sessions to ISO filesystems on
DVD other than DVD-RW, DVD-R, DVD+R see the advise to use dvd+rw-tools at
the end of this text.
--------------------------------------------------------------------------
About the command line options of cdrskin:
They are described in detail in [http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html#OPTIONS section OPTIONS] of
[http://scdbackup.sourceforge.net/man_1_cdrskin_devel.html man cdrskin]
There are two families of options: cdrecord-compatible ones and options
which are specific to cdrskin. The latter are mostly used to configure
cdrskin for its task to emulate cdrecord. There are some, nevertheless,
which provide rather exotic unique features of cdrskin.
The cdrecord-compatible options are listed in the output of
{{{
cdrskin -help
}}}
where the option "help" has *one* dash. Online: [http://scdbackup.sourceforge.net/cdrskin_help_devel cdrskin -help]
For these options you may expect program behavior that is roughly the
same as described in original man cdrecord .
Online: http://cdrecord.berlios.de/old/private/man/cdrecord-2.0.html
The cdrskin-specific options are listed by
{{{
cdrskin --help
}}}
where the option "help" has *two* dashes. Online: [http://scdbackup.sourceforge.net/cdrskin__help_devel cdrskin --help]
Some are very experimental and should only be
used in coordination with the libburnia developer team.
Some are of general user interest, though:
--------------------------------------------------------------------------
--devices allows the sysadmin to scan the system for possible drives
and displays their detected properties.
The drives are listed one per line, with fields:
libburn-drive-number, sysadmin-device-file, permissions, vendor, type
{{{
0 dev='/dev/sg0' rwrw-- : 'HL-DT-ST' 'DVDRAM GSA-4082B'
}}}
This feature is valuable since cdrskin -scanbus will not give you
the device file name and its current permissions.
cdrskin will accept of course the proposed dev= option as address
for any usage of the drive.
Different from cdrecord, cdrskin is intended to be run without special
privileges, i.e. no superuser setuid. It is intended that the sysadmin
controls drive accessability by rw-permissions of the drive rather than
by x-permission of the burn binary. To be usable with cdrskin, the drive
has to offer both, r- and w-permission.
--------------------------------------------------------------------------
The DVD capabilities of cdrskin differ from those of cdrecord-ProDVD. cdrskin
offers TAO-like multi-session with DVD-R[W], DVD+R and TAO-like single session
with overwriteable DVD media. It also offers DAO on DVD-R[W] which is probably
the same as the traditional cdrecord-ProDVD write mode.
Non-cdrecord blank mode blank=format_overwrite brings a DVD-RW
disc from its initial profile "Sequential Recording" into profile state
"Restricted Overwrite".
{{{
cdrskin dev=/dev/sr0 -v blank=format_overwrite
}}}
DVD-RAM, DVD+RW and overwriteable DVD-RW appear to cdrskin as blank media
which are capable of taking only a single track. This track may be positioned
on a 32KiB aligned address, though.
{{{
cdrskin ... write_start_address=2412m ...
}}}
Non-cdrecord blank mode blank=deformat_sequential brings an overwriteable
DVD-RW back into state "Sequential Recording" with the capability of doing
multi-session, if the drive is capable of "Incremental Streaming"
(MMC feature 21h).
Used sequential DVD-RW media may be blanked by blank=fast or blank=all which
normally both do full blanking.
blank=deformat_sequential does minimal blanking of DVD-RW which usually yields
media incapable of "Incremental Streaming".
Option --prodvd_cli_compatible activates blank=fast and blank=all for
overwriteable DVD-RW which normally ignore those two options. It also makes
option -multi tolerable with media and write modes which are not suitable for
multi-session. (The default behavior of cdrskin deems me to be preferrable.)
--------------------------------------------------------------------------
assert_write_lba=<lba> allows to ensure that the start block address which
was used with the formatter program (e.g. mkisofs -C) matches the start block
address which will be used by the upcoming burn.
E.g. cdrskin aborts with an error message if
{{{
assert_write_lba=0
}}}
is given but an appendable media is to be burned which would start ati
block 68432.
An ISO-9660 file system image must be prepared according to a particular
block address on media. If the prepared address and the real address on media
do not match then the filesystem will not be mountable or may even cause system
trouble.
A sequential archive format like afio or star will not necessarily need such
a coordination of addresses. It might nevertheless be confusing to a reader
if the archive does not start at block 0.
--------------------------------------------------------------------------
fifo_start_at=<num> is a throughput enhancer for unsteady data streams
like they are produced by a compressing archiver program when piping to
CD on-the-fly. It makes better use of the general property of a FIFO
buffer to transport surplus bandwidth into the future. Yep. A time machine.
One-way, i fear.
FIFO originally was introduced by cdrecord's author Joerg Schilling in order
to protect mediocre burner hardware from suffering buffer underruns
and thus producing misburns (at 1x speed on CD-R media at the price of a
DVD-RAM nowadays). This purpose would not justify a fifo any more -
given the limited life time of burners and the seamless underrun protection
of contemporary consumer drives.
With an unsteady data stream the task of the buffer is to soak up peak
performance and to release it steadily at the drive's maximum speed.
The larger the buffer the more reserves can be built up and the longer
input drought can be compensated.
Original cdrecord has the historical property, though, to first wait until
the buffer is completely filled. Best practice for fighting drive
underruns, of course.
With a very fat fs=# buffer (128 MB for 12x CD is not unrealistic) this
can cause a big delay until burning finally starts and takes its due time.
fifo_start_at=<num> makes cdrskin start burning after the given number of bytes
is read rather than waiting for the FIFO to be completely full resp. the data
stream to end. It risks a few drive buffer underruns at the beginning of burn
- but modern drives stand this.
Usage examples:
{{{
cdrskin ... fs=128m fifo_start_at=20m ...
cdrskin ... fifo_start_at=0 ...
}}}
Note: no FIFO can give you better average throughput than the average
throughput of the data source and the throughput of the burner.
It can be used, though, to bring the effective throughput very close
to the theoretical limit. Especially with high speed media.
--------------------------------------------------------------------------
--no_rc allows you to surely ban influence from systemwide or user specific
default settings of cdrskin. Possible locations for such settings:
/etc/default/cdrskin
/etc/opt/cdrskin/rc
/etc/cdrskin/cdrskin.conf
$HOME/.cdrskinrc
--------------------------------------------------------------------------
dev_translation=<sep><from><sep><to> may be needed to foist cdrskin to
frontend programs of cdrecord which do *not* ask cdrecord -scanbus but
which make own assumptions and guesses about cdrecord's device addresses.
Normally, cdrskin understands all addresses which are suitable for cdrecord
under Linux. See cdrskin/README, "Pseudo-SCSI Adresses".
This option is mainly for (yet unknown) exotic configurations or very
stubborn frontend programs.
If a frontend refuses to work with cdrskin, look into the error protocol
of that frontend, look at the output of a run of cdrskin --devices and give
cdrskin the necessary hint.
Example: Your frontend insists in using "0,0,0" and --devices reported
dev='/dev/hdc' resp. cdrskin dev=ATA -scanbus reported "1,0,0" then this
would be the appropriate translation:
{{{
dev_translation=+0,0,0+/dev/hdc
}}}
The "+" character is a separator to be choosen by you.
Currently i am not aware of the need to choose any other than "+"
unless you get playful with custom translations like
{{{
dev_translation=-"cd+dvd"-1,0,0
}}}
See http://scdbackup.sourceforge.net/k3b_on_cdrskin.html
for an illustrated example with K3b 0.10 .
--------------------------------------------------------------------------
DVD advise:
For burning of DVD media other than DVD-RAM, DVD+RW, DVD+R, DVD-RW, DVD-R,
the cdrskin project currently advises to use Andy Polyakov's dvd+rw-tools
which despite their historic name are capable of all the media above
and also do dual layer and even BD discs.
http://fy.chalmers.se/~appro/linux/DVD+RW/tools
They are not compatible or related to cdrecord resp. cdrecord-ProDVD
(now obsoleted by original source cdrtools cdrecord with identical
capabilities besides the license key).
A special feature of dvd+rw-tools is growing of ISO-9660 filesystems on
overwriteable media. This is not the same as multi-session writing of cdrskin
with CD media, but retrieves additional information from the existing ISO
image and finally manipulates the start sectors of this existing image.
So for growable ISO filesystems on DVD-RAM or DVD+RW growisofs is the only
choice, currently.
cdrskin can offer DVD multi-session only with sequential DVD-R[W] and with
DVD+R.
Associated options blank=, -multi, -msinfo and -toc are available in this case.
Thus sequential DVD-RW behave much like large CD-RW with possibly more than 99
tracks.

@author Mario Danic, Thomas Schmitt
@mainpage Libburnia Documentation Index
@section intro Introduction
Libburnia is an open-source project for reading, mastering and writing
optical discs.
For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD-RW, DVD-R.
Not supported yet are dual layer media, HD-DVD, BD (blue ray). Testers for
dual layer DVD+/-R are wanted, though.
The project comprises of several more or less interdependent parts which
together strive to be a usable foundation for application development.
These are libraries, language bindings, and middleware binaries which emulate
classical (and valuable) Linux tools.
Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
we would need : login on a development machine resp. a live OS on CD or DVD,
advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
volunteers for testing of realistic use cases.
We have a workable code base for burning data and audio CDs and many DVD types.
The burn API is quite comprehensively documented and can be used to build a
presentable application.
We have a functional binary which emulates the core use cases of cdrecord in
order to prove that usability, and in order to allow you to explore libburn's
scope by help of existing cdrecord frontends.
@subsection components The project components (list subject to growth, hopefully):
- libburn is the library by which preformatted data get onto optical media.
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
/dev/hdX (e.g. on kernel 2.6).
libburn is the foundation of our cdrecord emulation. Its code is
independent of cdrecord. Its DVD capabilities are learned from
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
- libisofs is the library to pack up hard disk files and directories into a
ISO 9660 disk image. This may then be brought to CD via libburn.
libisofs is to be the foundation of our upcoming mkisofs emulation.
- cdrskin is a limited cdrecord compatibility wrapper for libburn.
cdrecord is a powerful GPL'ed burn program included in Joerg
Schilling's cdrtools. cdrskin strives to be a second source for
the services traditionally provided by cdrecord. Additionally it
provides libburn's DVD capabilities, where only -sao is compatible
with cdrecord.
cdrskin does not contain any bytes copied from cdrecord's sources.
Many bytes have been copied from the message output of cdrecord
runs, though.
See cdrskin/README for more.
- "test" is a collection of application gestures and examples given by the
authors of the library features. The burn API example of libburn
is named test/libburner.c . The API for media information inquiry is
demonstrated in test/telltoc.c .
Explore these examples if you look for inspiration.
We plan to be a responsive upstream. Bear with us.
@section using Using the libraries
Our build system is based on autotools.
User experience tells us that you will need at least autotools version 1.7.
To build libburn and its subprojects it should be sufficient to go into
its toplevel directory and execute
- ./bootstrap (needed if you downloaded from SVN)
- ./configure
- make
To make the libraries accessible for running resp. developing applications
- make install
Both libraries are written in C language and get built by autotools.
Thus we expect them to be useable by a wide range of Linux-implemented
languages and development tools.
@section libburner Libburner
libburner is a minimal demo application for the library libburn
(see: libburn/libburn.h) as provided on http://libburn.pykix.org .
It can list the available devices, can blank a CD-RW or DVD-RW and
can burn to recordable CD and recordable single layer DVD.
It's main purpose, nevertheless, is to show you how to use libburn and also
to serve the libburnia team as reference application. libburner does indeed
define the standard way how above three gestures can be implemented and
stay upward compatible for a good while.
@subsection libburner-help Libburner --help
<pre>
Usage: test/libburner
[--drive <address>|<driveno>|"-"] [--audio]
[--blank_fast|--blank_full|--format_overwrite]
[--try_to_simulate]
[--multi] [<one or more imagefiles>|"-"]
Examples
A bus scan (needs rw-permissions to see a drive):
test/libburner --drive -
Burn a file to drive chosen by number, leave appendable:
test/libburner --drive 0 --multi my_image_file
Burn a file to drive chosen by persistent address, close:
test/libburner --drive /dev/hdc my_image_file
Blank a used CD-RW (is combinable with burning in one run):
test/libburner --drive /dev/hdc --blank_fast
Blank a used DVD-RW (is combinable with burning in one run):
test/libburner --drive /dev/hdc --blank_full
Format a DVD-RW to avoid need for blanking before re-use:
test/libburner --drive /dev/hdc --format_overwrite
Burn two audio tracks (to CD only):
lame --decode -t /path/to/track1.mp3 track1.cd
test/dewav /path/to/track2.wav -o track2.cd
test/libburner --drive /dev/hdc --audio track1.cd track2.cd
Burn a compressed afio archive on-the-fly:
( cd my_directory ; find . -print | afio -oZ - ) | \
test/libburner --drive /dev/hdc -
To be read from *not mounted* media via: afio -tvZ /dev/hdc
</pre>
libburner has two companions, telltoc and dewav, which help to perform some
peripheral tasks of burning.
telltoc prints a table of content (sessions, tracks and leadouts), it tells
about type and state of media, and also is able to provide the necessary
multi-session information for program mkisofs option -C. Especially helpful
are its predictions with "Write multi" and "Write modes" where availability
of "TAO" indicates that tracks of unpredicted length can be written.
See: test/telltoc --help.
dewav extracts raw byte-swapped audio data from files of format .wav (MS WAVE)
or .au (SUN Audio). See example in libburner --help.

Users of modern desktop Linux installations report misburns with CD/DVD
recording due to concurrency problems.
This text describes two locking protocols which have been developed by our
best possible effort. But finally they rather serve as repelling example of
what would be needed in user space to achieve an insufficient partial solution.
Ted Ts'o was so friendly to help as critic with his own use cases. It turned
out that we cannot imagine a way in user space how to cover reliably the needs
of callers of libblkid and the needs of our burn programs.
-------------------------------------------------------------------------------
Content:
The "Delicate Device Locking Protocol" shall demonstrate our sincere
consideration of the problem.
"What are the Stumble Stones ?" lists reasons why the effort finally failed.
-----------------------------------------------------------------------------
Delicate Device Locking Protocol
(a joint sub project of cdrkit and libburnia)
(contact: scdbackup@gmx.net )
Our projects provide programs which allow recording of data on CD or DVD.
We encounter an increasing number of bug reports about spoiled burn runs and
wasted media which obviously have one common cause: interference by other
programs which access the drive's device files.
There is some riddling about which gestures exactly are dangerous for
ongoing recordings or can cause weirdly misformatted drive replies to MMC
commands.
We do know, nevertheless, that these effects do not occur if no other program
accesses a device file of the drive while our programs use it.
DDLP shall help to avoid collisions between programs in the process of
recording to a CD or DVD drive and other programs which access that drive.
The protocol intends to provide advisory locking. So any good-willing program
has to take some extra precautions to participate.
If a program does not feel vulnerable to disturbance, then the precautions
impose much less effort than if the program feels the need for protection.
Two locking strategies are specified:
DDLP-A operates on device files only. It is very Linux specific.
DDLP-B adds proxy lock files, inspired by FHS /var/lock standard.
DDLP-A
This protocol relies on the hardly documented feature open(O_EXCL | O_RDWR)
with Linux device files and on POSIX compliant fcntl(F_SETLK).
Other than the original meaning of O_EXCL with creating regular files, the
effect on device files is mutual exclusion of access. I.e. if one
filedescriptor is open on that combination of major-minor device number, then
no other open(O_EXCL) will succeed. But open() without O_EXCL would succeed.
So this is advisory and exclusive locking.
With kernel 2.6 it seems to work on all device drivers which might get used
to access a CD/DVD drive.
The vulnerable programs shall not start their operation before they occupied a
wide collection of drive representations.
Non-vulnerable programs shall take care to detect the occupation of _one_ such
representation.
So for Friendly Programs
A program which does not feel vulnerable to disturbance is urged to access
CD/DVD drives by opening a file descriptor which will uphold the lock
as long as it does not get closed. There are two alternative ways to achieve
this.
Very reliable is
open( some_path , O_EXCL | ...)
But O_EXCL imposes restrictions and interferences:
- O_EXCL | O_RDONLY does not succeed with /dev/sg* !
- O_EXCL cannot provide shared locks for programs which only want to lock
against burn programs but not against their own peers.
- O_EXCL keeps from obtaining information by harmless activities.
- O_EXCL already has a meaning with devices which are mounted as filesystems.
This priority meaning is more liberal than the one needed for CD/DV recording
protection.
So it may be necessary to use a cautious open() without O_EXCL and to aquire
a POSIX lock via fcntl(). "Cautious" means to add O_NDELAY to the flags of
open(), because this is declared to avoid side effects within open().
With this gesture it is important to use the paths expected by our burn
programs: /dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
because fcntl(F_SETLK) does not lock the device but only a device-inode.
std_path = one of the standard device files:
/dev/sr[0..255] /dev/scd[0..255] /dev/sg[0..255] /dev/hd[a..z]
or a symbolic link pointing to one of them.
open( std_path , ... | O_NDELAY)
fcntl(F_SETLK) and close() on failure
... eventually disable O_NDELAY by fcntl(F_SETFL) ...
There is a pitfall mentioned in man 2 fcntl :
"locks are automatically released [...] if it closes any file descriptor
referring to a file on which locks are held. This is bad [...]"
So you may have to re-lock after some temporary fd got closed.
Vulnerable Programs
For programs which do feel vulnerable, O_EXCL would suffice for the /dev/hd*
device file family and their driver. But USB and SATA recorders appear with
at least two different major-minor combinations simultaneously.
One as /dev/sr* alias /dev/scd*, the other as /dev/sg*.
The same is true for ide-scsi or recorders attached to SCSI controllers.
So, in order to lock any access to the recorder, one has to open(O_EXCL)
not only the device file that is intended for accessing the recorder but also
a device file of any other major-minor representation of the recorder.
This is done via the SCSI address parameter vector (Host,Channel,Id,Lun)
and a search on standard device file paths /dev/sr* /dev/scd* /dev/sg*.
In this text the alternative device representations are called "siblings".
For finding them, it is necessary to apply open() to many device files which
might be occupied by delicate operations. On the other hand it is very
important to occupy all reasonable representations of the drive.
So the reading of the (Host,Channel,Id,Lun) parameters demands an
open(O_RDONLY | O_NDELAY) _without_ fcntl() in order to find the outmost
number of representations among the standard device files. Only ioctls
SCSI_IOCTL_GET_IDLUN and SCSI_IOCTL_GET_BUS_NUMBER are applied.
Hopefully this gesture is unable to cause harmful side effects on kernel 2.6.
At least one file of each class sr, scd and sg should be found to regard
the occupation as satisfying. Thus corresponding sr-scd-sg triplets should have
matching ownerships and access permissions.
One will have to help the sysadmins to find those triplets.
A spicy detail is that sr and scd may be distinct device files for the same
major-minor combination. In this case fcntl() locks on both are needed
but O_EXCL can only be applied to one of them.
An open and free implementation ddlpa.[ch] is provided as
http://libburnia.pykix.org/browser/libburn/trunk/libburn/ddlpa.h?format=txt
http://libburnia.pykix.org/browser/libburn/trunk/libburn/ddlpa.c?format=txt
The current version of this text is
http://libburnia.pykix.org/browser/libburn/trunk/doc/ddlp.txt?format=txt
Put ddlpa.h and ddlpa.c into the same directory and compile as test program by
cc -g -Wall -DDDLPA_C_STANDALONE -o ddlpa ddlpa.c
Use it to occupy a drive's representations for a given number of seconds
./ddlpa /dev/sr0 300
It should do no harm to any of your running activities.
If it does: Please, please alert us.
Your own programs should not be able to circumvent the occupation if they
obey above rules for Friendly Programs.
Of course ./ddlpa should be unable to circumvent itself.
A successfull occupation looks like
DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/scd0") = "/dev/sr0"
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/scd0"
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sg0"
DDLPA_DEBUG: ddlpa_occupy() : '/dev/scd0'
DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/sg0'
DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/sr0'
---------------------------------------------- Lock gained
ddlpa: opened /dev/sr0
ddlpa: opened siblings: /dev/scd0 /dev/sg0
slept 1 seconds of 300
Now an attempt via device file alias /dev/NEC must fail:
DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/NEC") = "/dev/sg0"
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sr0"
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/scd0"
DDLPA_DEBUG: ddlpa_collect_siblings() found "/dev/sg0"
Cannot exclusively open '/dev/sg0'
Reason given : Failed to open O_RDWR | O_NDELAY | O_EXCL : '/dev/sr0'
Error condition : 16 'Device or resource busy'
With hdc, of course, things are trivial
DDLPA_DEBUG: ddlpa_std_by_rdev("/dev/hdc") = "/dev/hdc"
DDLPA_DEBUG: ddlpa_occupy() O_EXCL : '/dev/hdc'
---------------------------------------------- Lock gained
ddlpa: opened /dev/hdc
slept 1 seconds of 1
Ted Ts'o provided program open-cd-excl which allows to explore open(2) on
device files with combinations of read-write, O_EXCL, and fcntl().
(This does not mean that Ted endorsed our project yet. He helps exploring.)
Friendly in the sense of DDLP-A would be any run which uses at least one of
the options -e (i.e. O_EXCL) or -f (i.e. F_SETLK, applied to a file
descriptor which was obtained from a standard device file path).
The code is available under GPL at
http://libburnia.pykix.org/browser/libburn/trunk/test/open-cd-excl.c?format=txt
To be compiled by
cc -g -Wall -o open-cd-excl open-cd-excl.c
Options:
-e : open O_EXCL
-f : aquire lock by fcntl(F_SETLK) after sucessful open
-i : do not wait in case of success but exit 0 immediately
-r : open O_RDONLY , with -f use F_RDLCK
-w : open O_RDWR , with -f use F_WRLCK
plus the path of the devce file to open.
Friendly Programs would use gestures like:
./open-cd-excl -e -r /dev/sr0
./open-cd-excl -e -w /dev/sg1
./open-cd-excl -e -w /dev/black-drive
./open-cd-excl -f -r /dev/sg1
./open-cd-excl -e -f -w /dev/sr0
Ignorant programs would use and cause potential trouble by:
./open-cd-excl -r /dev/sr0
./open-cd-excl -w /dev/sg1
./open-cd-excl -f -w /dev/black-drive
where "/dev/black-drive" is _not_ a symbolic link to
any of /dev/sr* /dev/scd* /dev/sg* /dev/hd*, but has an own inode.
Prone to failure without further reason is:
./open-cd-excl -e -r /dev/sg1
----------------------------------------------------------------------------
DDLP-B
This protocol relies on proxy lock files in some filesystem directory. It can
be embedded into DDLP-A or it can be used be used standalone, outside DDLP-A.
DDLP-A shall be kept by DDLP-B from trying to access any device file which
might already be in use. There is a problematic gesture in DDLP-A when SCSI
address parameters are to be retrieved. For now this gesture seems to be
harmless. But one never knows.
Vice versa DDLP-B may get from DDLP-A the service to search for SCSI device
file siblings. So they are best as a couple.
But they are not perfect. Not even as couple. fcntl() locking is flawed.
There is a proxy file locking protocol described in FHS:
http://www.pathname.com/fhs/pub/fhs-2.3.html#VARLOCKLOCKFILES
But it has shortcommings (see below). Decisive obstacle for its usage are the
possibility for stale locks and the lack of shared locks.
DDLP-B rather defines a "path prefix" which is advised to be
/tmp/ddlpb-lock-
This prefix will get appended "device specific suffixes" and then form the path
of a "lockfile".
Not the existence of a lockfile but its occupation by an fcntl(F_SETLK) will
constitute a lock. Lockfiles may get prepared by the sysadmin in directories
where normal users are not allowed to create new files. Their rw-permissions
then act as additional access restriction to the device files.
The use of fcntl(F_SETLK) will prevent any stale locks after the process ended.
It will also allow to obtain shared locks as well as exclusive locks.
There are two classes of device specific suffixes:
- Device file path suffix. Absolute paths only. "/" gets replaced by "_-".
Eventual "_-" in path gets replaced by "_-_-". The leading group of "_-"
is always interpreted as a group of "/", though. E.g.:
/dev/sr0 <-> "_-dev_-sr0"
/mydevs/burner/nec <-> "_-mydevs_-burners_-nec"
/dev/rare_-name <-> "_-dev_-rare_-_-name"
///strange/dev/x <-> "_-_-_-strange_-dev_-x"
- st_rdev suffix. A hex representation of struct stat.st_rdev. Capital letters.
The number of characters is pare with at most one leading 0. I.e. bytewise
printf("%2.2X") beginning with the highest order byte that is not zero.
E.g. : "0B01", "2200", "01000000000004001"
If a lockfile does not exist and cannot be created then this shall not keep
a program from working on a device. But if a lockfile exists and if permissions
or locking state do not allow to obtain a lock of the appropirate type, then
this shall prevent any opening of device file in question resp. shall cause
immediate close(2) of an already opened device file.
The vulnerable programs shall not start their operation before they locked a
wide collection of drive representations.
Non-vulnerable programs shall take care to lock the suffix resulting from the
path they will be using and the suffix from the st_rdev from that path.
The latter is to be obtained by call stat(2).
Locks get upheld as long as their file descriptor is not closed or no other
incident as described in man 2 fcntl releases the lock.
So with shared locks there are no imandatory further activities after they
have been obtained.
In case of exclusive locks, the file has to have been opened for writing and
must be truncated to 0 bytes length immediately after obtaining the lock.
When releasing an exclusive lock it is a nice gesture to
already do this truncation.
Then a /var/lock/ compatible first line has to be written.
E.g. by: printf("%10u\n",(unsigned) getpid()) yielding " 1230\n".
Any further lines are optional. They shall have the form Name=Value and must
be printable cleartext. If such further lines exist, then the last one must
have the name "endmark".
Defined Names are:
hostid =hostname of the machine where the process number of line 1 is valid
start =start time of lock in seconds since 1970. E.g: 1177147634.592410
program =self chosen name of the program which obtained the lock
argv0 =argv[0] of that program
mainpath =device file path which will be used for operations by that program
path =device file path which lead to the lock
st_rdev =st_rdev suffix which is associated with path
scsi_hcil=eventual SCSI parameters Host,Channel,Id,Lun
scsi_bus =eventual SCSI parameter Bus
endmark =declares the info as complete.
Any undefined name or a line without "=" shall be handled as comment.
"=" in the value is allowed. Any line beginning with an "=" character is an
extension of the previous value.
If programs encounter an exclusive lock, they are invited to read the content
of the lockfile anyway. But they should be aware that the info might be in the
progress of emerging. There is a race condition possible in the short time
between obtaining the exclusive lock and erasing the file content.
If it is not crucial to obtain most accurate info then one may take the newline
of the first line as indicator of a valid process number and the "endmark"
name as indicator that the preceding lines are valid.
Very cautious readers should obtain the info twice with a decent waiting period
inbetween. Only if both results are identical they should be considered valid.
There is no implementation of DDLP-B yet.
----------------------------------------------------------------------------
What are the Stumble Stones ?
----------------------------------------------------------------------------
Any of the considered locking mechanisms has decisive shortcommings
which keeps it from being the solution to all known legitimate use cases.
The attempt has failed to compose a waterproof locking mechanism from means of
POSIX, FHS and from hardly documented Linux open(O_EXCL) on device files.
The resulting mechanisms would need about 1000 lines of code and still do
not close all gaps resp. cover the well motivated use cases.
This attempt you see above: DDLP-A and DDLP-B.
Summary of the reasons why the established locking mechanisms do not suffice:
None of the mechanisms can take care of the double device driver identity
sr versus sg. To deduce the one device file from the other involves the need
to open many other (possibly unrelated) device files with the risk to disturb
them.
This hard to solve problem is aggravated by the following facts.
Shortcommings of Linux specific open(O_EXCL) :
- O_EXCL | O_RDONLY does not succeed with /dev/sg*
- O_EXCL cannot provide shared locks for programs which only want to lock
against burn programs but not against their own peers.
- O_EXCL keeps from obtaining information by harmless activities.
- O_EXCL already has a meaning with devices which are mounted as filesystems.
This priority meaning is more liberal than the one needed for CD/DV recording
protection.
Shortcommings of POSIX fcntl(F_SETLK) :
- fcntl() demands an open file descriptor. open(2) might have side effects.
- fcntl() locks can be released inadvertedly by submodules which just open and
close the same file (inode ?) without refering to fcntl locks in any way.
See man 2 fcntl "This is bad:".
Stacking of software modules is a widely used design pattern. But fcntl()
cannot cope with that.
Shortcommings of FHS /var/lock/ :
- Stale locks are possible.
- It is necessary to create a file (using the _old_ meaning of O_EXCL flag ?)
but /var/lock/ might not be available early during system start and it often
has restrictive permission settings.
- There is no way to indicate a difference between exclusive and shared locks.
- The FHS prescription relies entirely on the basename of the device file path.

/*
This is the main operating system dependent SCSI part of libburn. It implements
the transport level aspects of SCSI control and command i/o.
Present implementation: FreeBSD CAM (untested)
PORTING:
Porting libburn typically will consist of adding a new operating system case
to the following switcher files:
os.h Operating system specific libburn definitions and declarations.
sg.c Operating system dependent transport level modules.
and of deriving the following system specific files from existing examples:
os-*.h Included by os.h. You will need some general system knowledge
about signals and knowledge about the storage object needs of your
transport level module sg-*.c.
sg-*.c This source module. You will need special system knowledge about
how to detect all potentially available drives, how to open them,
eventually how to exclusively reserve them, how to perform
SCSI transactions, how to inquire the (pseudo-)SCSI driver.
You will not need to care about CD burning, MMC or other high-level
SCSI aspects.
Said sg-*.c operations are defined by a public function interface, which has
to be implemented in a way that provides libburn with the desired services:
sg_give_next_adr() iterates over the set of potentially useful drive
address strings.
scsi_enumerate_drives() brings all available, not-whitelist-banned, and
accessible drives into libburn's list of drives.
sg_drive_is_open() tells wether libburn has the given drive in use.
sg_grab() opens the drive for SCSI commands and ensures
undisturbed access.
sg_release() closes a drive opened by sg_grab()
sg_issue_command() sends a SCSI command to the drive, receives reply,
and evaluates wether the command succeeded or shall
be retried or finally failed.
sg_obtain_scsi_adr() tries to obtain SCSI address parameters.
Porting hints are marked by the text "PORTING:".
