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.

|
||||
Build and Installation
|
||||
|
||||
From tarball
|
||||
|
||||
Obtain libburn-1.1.8.tar.gz, take it to a directory of your choice and do:
|
||||
|
||||
tar xzf libburn-1.1.8.tar.gz
|
||||
cd libburn-1.1.8
|
||||
./configure --prefix=/usr
|
||||
make
|
||||
|
||||
To make libburn accessible for running resp. application development,
|
||||
and to install the cdrecord compatibility binary cdrskin, do
|
||||
(as Superuser):
|
||||
|
||||
make install
|
||||
|
||||
This procedure installs libburn.so.4 and cdrskin depending on it.
|
||||
For a standalone cdrskin binary, see cdrskin/README.
|
||||
|
||||
A behavioral conflict is known between any burn software and demons like hald
|
||||
which probe CD drives. This can spoil burn runs for CD-R or CD-RW.
|
||||
You may have to keep your hald away from the drive. See for example
|
||||
http://www.freebsd.org/gnome/docs/halfaq.html
|
||||
|
||||
|
||||
From SVN
|
||||
|
||||
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.
|
||||
Do in a directory of your choice:
|
||||
|
||||
svn co http://svn.libburnia-project.org/libburn/trunk libburn-svn
|
||||
cd libburn-svn
|
||||
Check out from SVN by
|
||||
svn co http://libburn-svn.pykix.org/trunk libburn_pykix
|
||||
and apply autotools by
|
||||
./bootstrap
|
||||
./configure --prefix=/usr
|
||||
|
||||
Alternatively you may unpack a release tarball for which you do not need
|
||||
autotools installed.
|
||||
|
||||
To build libburn.pykix.org and its subprojects 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
|
||||
|
||||
Warning: The trunk might contain experimental features which might not
|
||||
persist until next release.
|
||||
|
||||
|
||||
Special ./configure options
|
||||
|
||||
make install on GNU/Linux will try to run program ldconfig with the library
|
||||
installation directory as only argument. Failure to do so will not abort
|
||||
installation. One may disable ldconfig by ./configure option:
|
||||
--disable-ldconfig-at-install
|
||||
|
||||
In some situations Linux may deliver a better write performance to drives if
|
||||
the track input is read with O_DIRECT (see man 2 open). The API call
|
||||
burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
|
||||
can be told to use this peculiar read mode by:
|
||||
--enable-track-src-odirect
|
||||
|
||||
But often libburn call burn_write_opts_set_dvd_obs(opts, 64*1024) will yield
|
||||
even better performance in such a situation. 64k can be made default at
|
||||
configure time by:
|
||||
--enable-dvd-obs-64k
|
||||
This may be combined with above --enable-track-src-odirect .
|
||||
|
||||
Alternatively the transport of SCSI commands can be done via libcdio-0.83.
|
||||
You may install it and re-run libburn's ./configure with option
|
||||
--enable-libcdio
|
||||
|
||||
By use of a version script, the libburn.so library exposes no other function
|
||||
names but those of the API definition in libburn/libburn.h.
|
||||
If -Wl,--version-script=... makes problems with the local compiler, then
|
||||
disable this encapsulation feature by
|
||||
--disable-versioned-libs
|
||||
|
||||
Make sure to re-compile all source files after running ./configure
|
||||
make clean ; make
|
||||
make install
|
||||
|
||||
|
||||
Linux only:
|
||||
|
||||
libburn tries to avoid a collision with udev's drive examination by waiting
|
||||
0.1 seconds before opening the device file for a longer time, after udev
|
||||
might have been alarmed by drive scanning activities.
|
||||
The waiting time can be set at ./configure time with microsecond granularity.
|
||||
E.g. 2 seconds:
|
||||
CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=2000000"
|
||||
./configure ...options...
|
||||
Waiting can be disabled by zero waiting time:
|
||||
CFLAGS="$CFLAGS -DLibburn_udev_wait_useC=0"
|
||||
Alternatively, libburn can try to be nice by opening the device file,
|
||||
closing it immediately, waiting, and only then opening it for real:
|
||||
CFLAGS="$CFLAGS -DLibburn_udev_extra_open_cyclE -DLibburn_udev_wait_useC=500000"

|
||||
|
||||
|
||||
Overview of libburnia-project.org
|
||||
|
||||
libburnia-project.org is an open-source software project for reading, mastering
|
||||
and writing optical discs.
|
||||
For now this means CD media, all DVD media, all BD media.
|
||||
libburn.pykix.org is an open-source library for reading, mastering and writing
|
||||
optical discs. For now this means only CD-R and CD-RW.
|
||||
|
||||
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.
|
||||
Currently it is supported on GNU/Linux with kernels >= 2.4,
|
||||
on FreeBSD with ATAPI/CAM enabled in the kernel (see man atapicam),
|
||||
and on OpenSolaris (tested with kernel 5.11).
|
||||
On other X/Open compliant systems there will only be pseudo drives, but no
|
||||
direct MMC operation on real CD/DVD/BD drives.
|
||||
|
||||
For full 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.
|
||||
Our scope is currently Linux 2.4 and 2.6 and we will have a hard time to widen
|
||||
this for now, because of our history. The project could need advise from or
|
||||
membership of skilled kernel people and people who know how to talk CD/DVD
|
||||
drives into doing things.
|
||||
|
||||
We have a well tested code base for burning data and audio CDs, DVDs and BDs.
|
||||
The burn API is quite comprehensively documented and can be used to build a
|
||||
presentable application.
|
||||
We have a functional application 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.
|
||||
|
||||
ISO 9660 filesystems with Rock Ridge and Joliet extensions can be created
|
||||
and manipulated quite freely. This capability together with our burn capability
|
||||
makes possible a single binary application which covers all steps of image
|
||||
composition, updating and writing. Quite unique in the Linux world.
|
||||
We do have a workable code base for burning data CDs, though. The burn API is
|
||||
quite comprehensively documented and can be used to build a presentable
|
||||
application.
|
||||
We do have a functional binary which emulates parts 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.
|
||||
|
||||
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/srM 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.
|
||||
/dev/hdX (e.g. on kernel 2.6).
|
||||
libburn is the foundation of our cdrecord emulation.
|
||||
|
||||
- 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.
|
||||
An own ISO 9660 extension stores ACLs, xattr, and MD5 of file
|
||||
content.
|
||||
|
||||
- libisoburn is an add-on to libburn and libisofs which coordinates both and
|
||||
also allows to grow ISO-9660 filesystem images on multi-session
|
||||
media as well as on overwriteable media via the same API.
|
||||
All media peculiarities are handled automatically.
|
||||
It also contains the methods of command oriented application
|
||||
xorriso and offers them via a C language API.
|
||||
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
|
||||
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.
|
||||
the services traditionally provided by 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.
|
||||
|
||||
- xorriso is an application of all three libraries which creates, loads,
|
||||
manipulates and writes ISO 9660 filesystem images with
|
||||
Rock Ridge extensions. Manipulation is not only adding or
|
||||
overwriting of files but also deleting, renaming, attribute
|
||||
changing, incremental backups, activating boot images, and
|
||||
extracting of files from ISO images to disk. There is also a
|
||||
sparse emulation of cdrecord and a more laborate one of mkisofs.
|
||||
All features of xorriso are also available via a C language API
|
||||
of libisoburn.
|
||||
A static compilation of xorriso and the libraries is dedicated
|
||||
to the GNU Operating System. See xorriso/README_gnu_xorriso .
|
||||
|
||||
- "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 .
|
||||
- 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 strive to be a responsive upstream.
|
||||
|
||||
Our libraries are committed to maintain older feature sets in newer versions.
|
||||
This applies to source code headers (API) as well as to linkable objects (ABI).
|
||||
The only exception from this rule is about non-release versions x.y.*[13579]
|
||||
which are allowed to introduce new features, change those new features in
|
||||
any way and even may revoke such new features before the next release of
|
||||
x.y.*[02468]. As soon as it is released, a feature is promised to persist.
|
||||
|
||||
SONAMES:
|
||||
libburn.so.4 (since 0.3.4, March 2007),
|
||||
libisofs.so.6 (since 0.6.2, February 2008),
|
||||
libisoburn.so.1 (since 0.1.0, February 2008).
|
||||
|
||||
Applications must use 64 bit off_t. E.g. by defining
|
||||
#define _LARGEFILE_SOURCE
|
||||
#define _FILE_OFFSET_BITS 64
|
||||
or take special precautions to interface with the libraries by 64 bit integers
|
||||
where the .h files prescribe off_t. To reduce libburn's off_t size to 32 bit
|
||||
will keep it from processing tracks of more than 2 GB size.
|
||||
We plan to be a responsive upstream. Bear with us. We are still practicing.

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.
|
||||
|
||||
- 23th April 2007 version 0.3.6 follows the unanimous opinion of Linux kernel
|
||||
people that one should not use /dev/sg on kernel 2.6.
|
||||
|
||||
- 31st July 2007 version 0.3.8 marks the first anniversary of libburn revival.
|
||||
We look back on improved stability, a substantially extended list of media
|
||||
and write modes, and better protection against typical user mishaps.
|
||||
|
||||
- 24th October 2007 version 0.4.0 is the foundation of new library libisoburn
|
||||
and an upcomming integrated application for manipulating and writing
|
||||
ISO 9660 + Rock Ridge images. cdrskin-0.4.0 got capabilities like growisofs
|
||||
by these enhancements: growing of overwriteable media and disk files.
|
||||
Taking again a bow towards Andy Polyakov.
|
||||
|
||||
- 26th Januar 2008 version 0.4.2 rectifies the version numbering so that we
|
||||
reliably release libburn.so.4 as should have been done since libburn-0.3.2.
|
||||
cdrskin now is by default linked dynamically and does a runtime check
|
||||
to ensure not to be started with a libburn which is older than itself.
|
||||
|
||||
- 3rd Feb 2008 libisofs-0.2.x (.so.5) has been deprecated.
|
||||
|
||||
- 14th Feb 2008 libisofs-0.6.2 permanently replaces the old libisofs-0.2.x.
|
||||
It is the first release of new libisofs.so.6 which will guarantee future
|
||||
API/ABI compatibility for its whole feature set.
|
||||
|
||||
- 15th Feb 2008 libisoburn-0.1.0 (.so.1) coordinates libisofs and libburn for
|
||||
the purpose of ISO image reading and writing. It emulates multi-session on
|
||||
overwriteable media. Application xorriso makes use of all three libraries.
|
||||
|
||||
- 8th Apr 2008 libburn-0.4.4 has proven to be capable of burning to DVD+R/DL
|
||||
and read performance on disk file pseudo-drives has been improved.
|
||||
|
||||
- 27th Apr 2008 libisofs-0.6.4 can now read data file content from images
|
||||
and can map pieces of disk files onto image files. Image directory iteration
|
||||
has been enhanced. Input data streams and extended information have been
|
||||
exposed in the API to allow future development.
|
||||
|
||||
- 29th Apr 2008 libisoburn-0.1.4 was made more efficient with reading of
|
||||
image tree nodes. It now depends on libisofs-0.6.4 and libburn-0.4.4.
|
||||
xorriso makes use of new libisofs features by performing incremental
|
||||
updates of directory trees and by cutting oversized data files into
|
||||
pieces. A primitive single session emulation of cdrecord and mkisofs is
|
||||
provided.
|
||||
|
||||
- 10th May 2008 libburn-0.4.6 supports formatting and writing of BD-RE,
|
||||
full nominal speed for DVD-RAM and BD-RE. cdrskin has a unified blank
|
||||
type with automatic media state recognition.
|
||||
|
||||
- 17th May 2008 an old bug with DVD-RAM and now with BD-RE is fixed by
|
||||
libburn-0.4.8 to allow libisoburn emulation of multisession on those media.
|
||||
|
||||
- 19th May 2008 libisoburn-0.1.6 brings better table-of-content emulation
|
||||
on overwriteble media and disk files.
|
||||
|
||||
- 1st Jun 2008 libisofs-0.6.6 fixes some problems around device files.
|
||||
|
||||
- 3rd Jun 2008 libisoburn-0.1.8 fixes a bug with overwriteable media.
|
||||
|
||||
- 23rd Jun 2008 libisoburn-0.2.0 introduces extraction of files from
|
||||
ISO images.
|
||||
|
||||
- 16th Jul 2008 libburn-0.5.0 handles systems with no /dev/sr* but only
|
||||
/dev/scd*.
|
||||
|
||||
- 19th Jul 2008 libisoburn/xorriso-0.2.2 can do multi-session in mkisofs
|
||||
and cdrecord style. xorriso now can serve underneath growisofs.
|
||||
|
||||
- 20th Aug 2008 libburn-0.5.2 revokes the necessity that a drive must be
|
||||
enumerable in order to be adressable. Enumeration is enhanced by examining
|
||||
/proc/sys/dev/cdrom/info.
|
||||
|
||||
- 24th Aug 2008 libisoburn/xorriso-0.2.4 introduces a media readability check
|
||||
with data retrieval option.
|
||||
|
||||
- 18th Sep 2008 libisofs-0.6.8 supports ISO 9660 Level 3 which allows very
|
||||
large data files in the image.
|
||||
|
||||
- 20th Sep 2008 libisoburn/xorriso-0.2.6 takes into respect the new Level 3
|
||||
capabilities of libisofs.
|
||||
|
||||
- 6th Oct 2008 libburn-0.5.4 adjusts the changes of 0.5.2 to the needs of
|
||||

|
||||
manipulation of ISOLINUX boot images.
|
||||
|
||||
- 15th Oct 2008 libisoburn/xorriso-0.2.8 can activate and maintain an

||||
- 26th Nov 2008 libisofs-0.6.12 can produce a ISOLINUX isohybrid MBR on the fly
|
||||
and allows to produce ISO images which resemble old mkisofs images.
|
||||
|
||||
- 2nd Dec 2008 libisoburn-0.3.0. xorriso now is ready for exotic character
|
||||
sets, for legacy FreeBSD systems which expect an outdated Rock Ridge
|
||||
signature, and for producing ISO images with MBR which boot from hard disk
|
||||
or USB stick. Three minor bugs were fixed.
|
||||
|
||||
- 7th Dec 2008 libburn-0.5.8 prevents a SIGSEGV with wierd CD table-of-content
|
||||
and improves BD-RE formatting.
|
||||
|
||||
- 9th Dec 2008 Our project received a donation from Thomas Weber.
|
||||
|
||||

|
||||
formatted or unformatted BD-R.
|
||||
|
||||
- 6th Jan 2009 libisoburn-0.3.2. xorriso can produce and execute commands for
|
||||
mounting older sessions from all kinds of media. Pseudo-drives outside the
|
||||
/dev/ tree can be addressed without prefix "stdio:".
|
||||
|

|
||||
capabilities provided by libisofs for xorriso backup features.
|
||||
|
||||
- 11 Mar 2009 libisofs-0.6.16 of libisofs fixes two bugs which on Solaris
|
||||
prevented to navigate the ISO images by ".." and to recognize the Rock Ridge
|
||||
extensions of ISO images. The ban to build libisofs on operating systems
|
||||
other than Linux and FreeBSD has been lifted.
|
||||
|
||||
- 13 Mar 2009 libburn-0.6.4 got a dummy adapter for SCSI/MMC command transport.
|
||||
It will show no drives and thus libburn will only be able to perform
|
||||
operations on "stdio:" pseudo drives. Nevertheless this allowed to lift the
|
||||
ban to build libburn on operating systems other than Linux and FreeBSD.
|
||||
|
||||
- 16 Mar 2009 libisoburn-0.3.6: xorriso uses RRIP version 1.10 as default
|
||||
in order to be mountable where mkisofs images are mountable.
|
||||
|
||||
- 17 Apr 2009 libisofs-0.6.18 introduces content filtering of data files.

and a bug with device scan on FreeBSD.
|
||||
|
||||
- 31 May 2009 libisofs-0.6.20 can record hard link relations in ISO images
|
||||
and offers support with restoring them to disk. Current Linux kernels will
|
||||
mount images with such hard links but will attribute a unique inode number
|
||||
to each file.
|
||||
|
||||
- 28 Jun 2009 libisoburn-0.4.0: xorriso can record and restore hard link
|
||||
relations of files. Performance of data reading has been improved. Option
|
||||
-find now supports logical operators with its tests.
|
||||
|
||||

|
||||
and with large SCSI bus numbers as handed out by Linux for USB drives.
|
||||
|
||||
- 20 Jul 2009 libisoburn-0.4.0.pl01 fixes a regression in xorriso which caused
|

|
||||
Affected are releases since libisoburn-0.3.2 in january 2009.
|
||||
|
||||
- 25 Aug 2009 libisofs-0.6.22 can record MD5 checksums for the whole session
|
||||
and for each single data file. Checksum tags allow to verify superblock and
|
||||
directory tree before importing them.
|
||||
|
||||
- 27 Aug 2009 libburn-0.7.0 allows to calm down a drive and to inquire its
|
||||
supported profiles. It works around some pitfalls with U3 enhanced memory
|
||||
sticks which emulate a CD-ROM.
|
||||
|
||||
- 27 Aug 2009 libisoburn-0.4.0.pl00 can record MD5 checksums by which one may
|
||||
verify the session or single data files in the image. When comparing image
|
||||
files with files in the local filesystem, the MD5 sums avoid the need for
|
||||
reading file content from the image.
|
||||
|
||||
- 22 Sep 2009 libisoburn-0.4.0.pl01 fixes a bug in xorriso option -cut_out.
|
||||
|
||||
- 08 Oct 2009 libisofs-0.6.24 fixes a bug which could cause the loss of blanks
|
||||
in file names when a new session got added to an ISO image. With names
|
||||
shorter than 251 characters this happened only to trailing blanks.
|
||||
|
||||
- 08 Oct 2009 libisoburn-0.4.0.pl02 fixes bugs with xorriso option -for_backup,
|
||||
with xorrisofs -help, and with xorrecord -help.
|
||||
|
||||
- 12 Oct 2009 libburn-0.7.2 fixes a bug with CD TAO multi-track dummy sessions.
|
||||
It can retrieve media product info and can process track input which was
|
||||
prepared for CD-ROM XA Mode 2 Form 1. cdrskin now performs option -minfo.
|
||||
|
||||
- 28 Oct 2009 libisoburn-0.4.4 fixes a bug with cdrecord emulation and
|
||||
introduces new information options about media type and ISO image id strings.
|
||||
On Linux it helps with mounting two sessions of the same media
|
||||
simultaneously.
|
||||
|
||||
- 12 Nov 2009 libburn-0.7.2.pl01 works around problems with Pioneer DVR-216D.
|
||||
DVD-R runs made the drive stuck. Ejecting the tray did not work properly.
|
||||
|
||||
- 06 Dec 2009 libburn-0.7.4 works around problems with newer DVD burners,
|
||||

for.
|
||||
|
||||
- Mon Jan 17 2011 we go for release 1.0.0. This does not indicate a
|
||||
technological overhaul but shall emphasize the maturity of the software.
|
||||
libisofs-1.0.0 fixes a bug about the length of ECMA-119 directory names and
|
||||
is ready to allow untranslated ECMA-119 names (violating the specs).
|
||||
libburn-1.0.0.pl00 allows umask to create stdio-drive files with
|
||||
rw-permissions for all. cdrskin now refuses to burn if the foreseeable size
|
||||
exceeds media capacity
|
||||
libisoburn-1.0.0.pl00 allows to create an ISO 9660:1999 directory tree,
|
||||
improved the emulation fidelity of command -as mkisofs, lowered the default
|
||||
abort threshold for xorriso batch mode, and increased that threshold for
|

|
||||
|
||||
- Wed Feb 23 2011 release 1.0.2:
|
||||
libisofs fixes several bugs and introduces the capability to copy files
|
||||
inside the ISO filesystem.
|
||||
libburn removed a compilation obstacle on Solaris 9 and improved recognition
|
||||
of stdio pseudo-drives.
|
||||
libisoburn and xorriso fix bugs and make use of the new libisofs capability.
|
||||
xorriso improves its mkisofs emulation.
|
||||
|
||||
- Thu Mar 10 2011 release 1.0.4:
|
||||
Several bugs were fixed in the libraries and in the mkisofs emulation of
|
||||
xorriso. This emulation xorrisofs has now an own man page and info document.
|
||||
|
||||
- Sat Apr 09 2011 release 1.0.6:
|
||||
libburn refined its representation of emulated drives. The size alignment
|
||||
of DVD DAO is now 2 kB rather than 32 kB. libisofs produces Joliet names of
|
||||
up to 103 characters. xorriso fixes two bugs and makes use of the library
|
||||
improvements.
|
||||
|
||||
- Thu Apr 14 2011 release libisoburn-1.0.8:
|
||||
A bug in the mkisofs emulation of xorriso could cause options to be ignored.
|
||||
The problem was freshly introduced with libisoburn-1.0.6.
|
||||
|
||||
- Fri May 13 2011 release libisofs-1.0.8:

||||
The consumption of stack memory was reduced. Statical program analysis found
|
||||
some rarely occuring memory leaks. Several small bugs were fixed.
|
||||
The suffix .plXY was dropped from tarball names of libburn and libisoburn.
|
||||
|
||||
- Mon Jun 20 2011 patch release libburn-1.1.0.pl01:
|
||||
libburn-1.1.0 compiled only on Linux, FreeBSD, and Solaris, but not on
|
||||
other X/Open compliant systems.
|
||||
|
||||
- Fri Jul 08 2011 release libisofs-1.1.2 and libisoburn-1.1.2:
|
||||
A severe regression was fixed in libisoburn and xorriso, which was introduced
|
||||
with version 1.0.6. It caused ISO 9660 images to be unreadable if they were
|
||||
written to a write-only random-access file. E.g. by: xorrisofs ... >image.iso
|
||||
|
||||
- Mon Aug 08 2011 release 1.1.4:
|
||||
Several bugs were fixed in libburn. The most severe of them prevented xorriso
|
||||
on some drives from burning mountable ISO 9660 images to CD media.
|
||||
New means to list drives by their udev symbolic links help to deal with
|
||||
the non-persistent drive addresses on modern GNU/Linux.
|
||||
|
||||
- Tue Sep 27 2011 release 1.1.6:
|
||||
libisoburn now comes with a test suite. See releng/README. Bugs were fixed
|
||||
in several rarely used features. Processing of ACL and extattr was enabled
|
||||
on FreeBSD. Workarounds try to cope with vanishing udev links on GNU/Linux.
|
||||
|
||||
- Mon Nov 21 2011 release libburn-1.1.8 and libisoburn-1.1.8:
|
||||
libburn avoids to close and open drive device files while operating on them.
|
||||
xorriso emulation mode xorrecord now has an own manual. libburn and xorriso
|
||||
were prepared to operate on qemu virtio-blk-pci devices.

On top of libburn there is implemented cdrskin 0.2.4, 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.
|
||||
|
||||
cdrskin is a limited cdrecord compatibility wrapper which allows to use
|
||||
most of the libburn features from the command line.
|
||||
|
||||
Currently it is supported on GNU/Linux with kernels >= 2.4,
|
||||
on FreeBSD and on OpenSolaris.
|
||||
IDE drives under Linux 2.4. need kernel module ide-scsi.
|
||||
ATA and SATA drives under FreeBSD need kernel module atapicam.
|
||||
On other X/Open compliant systems there will only be emulated drives, but no
|
||||
direct MMC operation on real CD/DVD/BD drives.
|
||||
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.
|
||||
|
||||
By using this software you agree to the disclaimer at the end of this text
|
||||
"This software is provided as is. There is no warranty implied and ..."
|
||||
I used it on my own risk with :
|

|
||||
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

||||
cd cdrskin-1.1.8
|

Within that directory execute:
|

Or obtain a libburn.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 .
|
||||
|
||||
./configure --prefix=/usr
|
||||
Within that toplevel directory of either cdrskin-0.2.4 or libburn then execute:
|
||||
|
||||
./configure
|
||||
make
|
||||
|
||||
This will already produce a cdrskin binary. But it will be necessary to
|
||||
install libburn in order to use this binary.
|
||||
(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.

makes it accessible. With the statically linked binary this should not matter.

With that static binary you may as well do the few necessary actions manually.

But libpthread must be installed on the system and glibc has to match. (See

A behavioral conflict is known between any burn software and demons like hald
|
||||
which probe CD drives. This can spoil burn runs for CD-R or CD-RW.

You may have to keep your hald away from the drive. See for example

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.
|
||||
For finding /dev/sg1 from /dev/sr0, the program needs rw-access to both files.

Several advanced CD related options of cdrecord are still unsupported.
|
||||
See output of command
|
||||
cdrskin --list_ignored_options
|
||||
If you have use cases for them, please report your wishes and expectations.
|
||||
The convenient burn mode TAO is not available with libburn yet.
|
||||
Therefore it has to be defaulted to mode SAO which needs to know the track
|
||||
size in advance. non-cdrecord option tao_to_sao_tsize=650m causes each CD
|
||||
to get burned up to 650 MB regardless of the payload size.
|
||||
|
||||
On the other hand, the capability of multi-session and of writing streams
|
||||
of unpredicted lenght surpass the current DVD capabilities of cdrecord.
|
||||
No multi session yet ... Please report your wishes.
|
||||
|
||||
|
||||
Inspiration and Standard
|
||||
|
||||
cdrskin combines the command line interface standard set by cdrecord with
|
||||
libburn, which is a control software for optical drives according to standard
|
||||
MMC-5. For particular CD legacy commands, standards MMC-3 and MMC-1 apply.
|
||||
|
||||
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.)
|
||||
|
||||
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.
|
||||
|
||||
Actually i, Thomas Schmitt, am a devoted user of cdrecord via my project
|
||||
scdbackup which still runs a bit better with cdrecord than with cdrskin. TAO.
|
||||
I have the hope that Joerg feels more flattered than annoyed by cdrskin.
|
||||
|
||||

|

|
||||
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
|
||||

||||
/etc/default/cdrskin
|
||||
/etc/defaults/cdrskin
|
||||
/etc/opt/cdrskin/rc
|
||||
/etc/cdrskin/cdrskin.conf

||||

DVD+RW , DVD-RAM , BD-RE
|
||||
|
||||
These random access 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) or BD units
|
||||
(1x = 4,495,625 bytes/second). Currently there is no difference between -sao
|
||||
and -tao. If ever, then -tao will be the mode which preserves the current
|
||||
behavior.
|
||||
|
||||
BD-RE media need formatting before first use. cdrskin option "blank=as_needed"
|
||||
recognizes unformatted BD-RE and applies a lengthy formatting run.
|
||||
|
||||
During write operations DVD-RAM and BD-RE automatically apply Defect
|
||||
Management. This usually slows them down to half nominal speed. If drive
|
||||
and media produce flawless results anyway, then one can try to reach full
|
||||
nominal speed by option "stream_recording=on".
|
||||
In this case bad blocks are not detected during write and not even previously
|
||||
known bad blocks are avoided. So you have to make your own readability tests
|
||||
and go back to half speed as soon as the first read errors show up.
|
||||
Instead of "on" one may also set a start address for stream recording.
|
||||
Like "stream_recording=100m". This will write slowly to the first 100 MB of
|
||||
the media and accelerate when writing to higher addresses.
|
||||
|
||||
Option --grow_overwriteable_iso allows -multi (although unneeded), enables
|
||||
-msinfo and -toc, and makes blank=fast an invalidator for ISO filesystems
|
||||
on overwriteable media.

||||
|
||||
Initial session (equivalent to growisofs -Z):

|
||||

DVD-RW , DVD-R , DVD-R DL
|
||||
|
||||
DVD-RW are usable if formatted to state "Restricted Overwrite" or if in state
|
||||
"Sequential Recording". DVD-R are always in sequential state. DVD-R DL are
|
||||
always sequential and incapable of multi-session.
|
||||
|
||||
"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 MiB. 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 , DVD+R DL , BD-R
|
||||
|
||||
From the view of cdrskin they behave much like DVD-R. Each track gets wrapped
|
||||
into an own session, though.
|
||||
|
||||
DVD+R DL appear as extra large DVD+R. cdrskin does not allow to set the address
|
||||
of the layer break where a reading drive might show some delay while switching
|
||||
between both media layers.
|
||||
|
||||
BD-R are sold unformatted blank. If used without initial formatting then the
|
||||
drive is supposed to format them to maximum payload size with no Defect
|
||||
Management (see also above with BD-RE).
|
||||
If Defect Management is desired then BD-R need to be formatted before the
|
||||
first attempt to write a session to them.
|
||||
blank=format_if_needed will detect the situation and eventually apply
|
||||
default sized Defect Management formatting.
|
||||
blank=format_defectmgt_* will apply non-default parameters to formatting.
|
||||
|
||||
|
||||
Emulated Drives
|
||||
|
||||
cdrskin can use filesystem objects as emulated drives. Regular files or block
|
||||
devices appear similar to DVD-RAM. Other file types resemble blank DVD-R.
|
||||
Necessary precondition is option --allow_emulated_drives which is not accepted
|
||||
if cdrskin took another user identity because of the setuid bit of its access
|
||||
permissions.
|
||||
Addresses of emulated drives begin with prefix "stdio:". E.g.
|
||||
dev=stdio:/tmp/my_pseudo_drive
|
||||
|
||||
For safety reasons the superuser is only allowed to use /dev/null as emulated
|
||||
drive. See man page section FILES for a way to lift that ban.
|
||||
|
||||

||||

Special compilation variations
|
||||
|
||||
All following options of ./configure and cdrskin/compile_cdrskin.sh are
|
||||
combinable. After runs of ./configure do as next:
|
||||
make clean ; make
|
||||
|
||||
In some situations Linux may deliver a better write performance to drives if
|
||||
the track input is read with O_DIRECT (see man 2 open). The API call
|
||||
burn_os_open_track_src() and the input readers of cdrskin and libburn fifo
|
||||
can be told to use this peculiar read mode by:
|
||||
--enable-track-src-odirect
|
||||
|
||||
But often cdrskin option dvd_obs=64k will yield even better performance in
|
||||
such a situation. 64k can be made default at compile time by
|
||||
cdrskin/compile_cdrskin.sh -dvd_obs_64k
|
||||
It can also be enabled at configure time by
|
||||
./configure ... --enable-dvd-obs-64k ...
|
||||
|
||||
Alternatively the transport of SCSI commands can be done via libcdio-0.83.
|
||||
You may install it and re-run libburn's ./configure with option
|
||||
--enable-libcdio
|
||||

0.1 seconds before opening the device file for a longer time, after udev

The waiting time can be set at ./configure time with microsecond granularity.

Waiting can be disabled by zero waiting time:

System Dependend Drive Permission Examples
|
||||
|
||||
Accessing the optical drives requires privileges which usually are granted
|
||||
only to the superuser. Linux, FreeBSD and Solaris offer quite different
|
||||
approaches for avoiding the need for unrestricted privileges.
|
||||
|
||||
First check whether some friendly system setting already allows you to
|
||||
access the drives as normal user:
|
||||
cdrskin --devices
|
||||
Those drives of which you see address and type strings are already usable.
|
||||
|
||||
If there remain drives invisible which the superuser can see by the same
|
||||
command, then the following examples might help:
|
||||
|
||||
---------------------
|
||||
On all three systems:
|
||||
---------------------
|
||||
Add the authorized users of CD drives to group "floppy" in /etc/group.
|
||||
If missing: create this group.
|
||||
Changes to /etc/group often only affect new login sessions. So log out and in
|
||||
before making the first tests.
|
||||
|
||||
---------
|
||||
On Linux:
|
||||
---------
|
||||
Allow rw-access to the drives
|
||||
chgrp floppy /dev/sr0 /dev/sr1
|
||||
chmod g+rw /dev/sr0 /dev/sr1
|
||||
It might be necessary to perform chgrp and chmod after each reboot or to
|
||||
edit distro dependent device configuration files for permanent settings.
|
||||
|
||||
-----------
|
||||
On FreeBSD:
|
||||
-----------
|
||||
Edit /etc/devfs.rules and make sure to have these lines
|
||||
[localrules=10]
|
||||
add path 'acd*' mode 0664 group floppy
|
||||
add path 'cd*' mode 0664 group floppy
|
||||
add path 'pass*' mode 0664 group floppy
|
||||
add path 'xpt*' mode 0664 group floppy
|
||||
[localrules=5]
|
||||
add path 'pass*' mode 0664 group floppy
|
||||
add path 'cd*' mode 0664 group floppy
|
||||
add path 'xpt*' mode 0664 group floppy
|
||||
add path 'acd*' mode 0664 group floppy
|
||||
|
||||
Edit /etc/rc.conf and add the following line if missing
|
||||
devfs_system_ruleset="localrules"
|
||||
|
||||
This gets into effect by reboot or by command
|
||||
/etc/rc.d/devfs start
|
||||
|
||||
-----------
|
||||
On Solaris:
|
||||
-----------
|
||||
Run cdrskin by
|
||||
pfexec cdrskin ...arguments...
|
||||
|
||||
The following settings will make pfexec keep original UID and EUID and prevent
|
||||
most superuser powers. Be aware that you still can manipulate all device files
|
||||
if you have the file permissions for that.
|
||||
Full root privileges for cdrskin can then be aquired only by command su.
|
||||
|
||||
Edit /etc/security/exec_attr and add this line to the other "Media Backup"
|
||||
lines:
|
||||
Media Backup:solaris:cmd:::/usr/local/bin/cdrskin:privs=basic,sys_devices
|
||||
Edit /etc/user_attr and add profile "Media Backup" to the user's line:
|
||||
thomas::::profiles=Media Backup,Primary Administrator;roles=root
|
||||
See also man privileges, man exec_attr, man user_attr.
|
||||
|
||||
Then allow the group r-access to the drives
|
||||
pfexec chgrp floppy /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
|
||||
pfexec chmod g+r /dev/rdsk/c3t0d0s2 /dev/rdsk/c4t0d0s2
|
||||
The last two commands have to be executed after each boot. I do not know
|
||||
the relevant device configuration files yet.

|

<DT>The most common options of cdrecord for data and audio on CD media
|
||||
are provided in a compatible way.<BR>
|
||||
On all DVD media, cdrskin is able to perform any recording job
|
||||
which is possible with cdrecord.
|
||||
Other than with cdrecord, option -multi is supported with many DVD types and
|
||||
BD-R. Write mode -tao works with anything but quickly blanked DVD-RW and
|
||||
DVD-R DL, which both support no -multi.
|
||||
</DT>
|
||||
<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>
|
||||
Further enhancements depend on people who can describe and discuss their
|
||||
wishes as well as on the development of libburn.</DT>

cdrskin -scanbus or --devices hangs for quite a while if there is
|
||||
a CD drive which does not work properly (e.g. because it has individual
|
||||
problems with DMA).
|
||||
So if the superuser gets no result with cdrskin --devices then one should
|
||||
disable DMA with the problematic CD drives
|
||||
(like: <KBD>hdparm -d0 /dev/hdd</KBD> )
|
||||
and try again.<BR>
|
||||
In severe cases it might be necessary to guess the device name /dev/sgN resp.
|
||||
/dev/hdX of the non-ill burner if it cannot be found otherwise among its
|
||||
ill peers. Alternatively one can guess the address of the ill device, remove
|
||||
rw-permissions and retry the bus scan as non-superuser.

'''cdrskin is the cdrecord compatibility middleware of libburn.'''
|
||||
cdrskin-0.2.3 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, DVD-RW, and BD-RE are handled differently
|
||||
than with cdrecord-ProDVD in order to offer TAO-like single track recording.
|
||||
Sequential DVD-R[W], DVD+R, DVD+R DL, BD-R are handled like CD-R[W] with TAO
|
||||
and multi-session. Additionally cdrskin offers cdrecord-ProDVD-like mode DAO
|
||||
with DVD-R[W].
|
||||
traditionally provided by cdrecord. Currently it does CD-R and CD-RW.
|
||||
Its future ability to burn DVD media depends on the development of libburn.
|
||||
|
||||
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-project.org/browser/libburn/trunk/cdrskin/README?format=txt cdrskin/README].
|
||||
|
||||
About libburn API for burning CD and DVD: http://api.libburnia-project.org
|
||||
can be found in cdrskin/README .

For yet unsupported media types see the advice to use dvd+rw-tools at

|
||||
cdrskin with CD media fails to match its paragon cdrecord on two major
|
||||
fields: convenient TAO burn mode and multi session.
|
||||
|
||||
cdrskin does not provide DVD burning yet. See advise to use dvd+rw-tools
|
||||

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,

If this is not possible, e.g. because the media is written and not

to the MMC standard but also does the same with regular files or block
|

devices other than optical drives.
|

|

Because the power to alter a disk file might be a bad surprise for a

traditional user of cdrecord, it is necessary to give option

--allow_emulated_drives before an emulated drive may be addressed.

The DVD capabilities of cdrskin differ from those of cdrecord-ProDVD. cdrskin
|
||||
offers TAO-like multi-session with DVD-R[W], DVD+R[ DL] 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".

|
||||
|
||||
DVD-RAM, DVD+RW, BD-RE 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. Thus sequential DVD-RW behave much like large
|
||||
CD-RW with possibly more than 99 tracks.
|
||||
|
||||
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.)
|
||||
|
||||
Option --grow_overwriteable_iso gives cdrskin ISO pseudo-multi-session
|
||||
capabilities on DVD-RAM, DVD+RW, BD-RE similar to growisofs.
|
||||
Associated options blank=, -multi, -msinfo and -toc are available in this case.
|
||||
They either pretend a blank media (if there is no ISO 9660 image) or appendable
|
||||
media with a single session and track on it. blank= invalidates ISO images.

Advanced multi-session use cases:
|
||||
|
||||
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, inspired by growisofs, cdrskin can offer DVD multi-session not only with
|
||||
sequential DVD-R[W] and with DVD+R [DL], but also with DVD-RAM, DVD+RW, BD-RE
|
||||
and even regular disk files or block devices other than CD/DVD writers.
|
||||
This is enabled by option --grow_overwriteable_iso.
|
||||
|
||||
The libburnia project provides an integrated ISO-9660 multi-session tool
|
||||
named [wiki:Xorriso xorriso] which tries to go one step beyond
|
||||
growisofs. It uses [wiki:Libburn libburn] , [wiki:Libisofs libisofs]
|
||||
and [wiki:Libisoburn libisoburn].
|
||||
|
||||
See [http://scdbackup.sourceforge.net/man_1_xorriso.html man xorriso].
|
||||
If there is sincere and well motivated interest, the cdrskin project could try
|
||||
to employ growisofs as DVD burning engine. The cdrskin project would prefer to
|
||||
wait for DVD support being included in libburn, though.
|
||||
A very limited and specialized cdrecord-compatibility wrapper for growisofs
|
||||
serves in my project scdbackup. It is not overly hard to make one that serves
|
||||
some very few fixed use cases.
|
||||
|
||||
To my knowledge, Linux kernels 2.6 do write to DVD+RW via block devices as
|
||||
they would write to a traditional tape device. Try old tape archiver
|
||||
commands with addresses like /dev/sr0 or /dev/hdc rather than /dev/mt0 .
|
||||
I have heard rumors that DVD-RW in mode "restricted overwrite" would be
|
||||
block device ready, too. My burner is not a real friend of DVD-RW and
|
||||
in an experiment the burn worked fine - but the result was not identical
|
||||
to the stream sent to the device. I had similar failure with DVD-RAM, too.
|
||||
|
||||
Beware of the impact of a slow block device on overall system i/o buffering.
|
||||
It is wise to curb its input to a speed which it is able to deliver to media.
|
||||
Else your i/o dedicated RAM might buffer a big amount of stream data.

@section intro Introduction
|
||||
|
||||
Libburnia is an open-source project for reading, mastering and writing
|
||||
optical discs. This page is about its capability to handle optical media.
|
||||
For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW,
|
||||
DVD-R, DVD-R/DL, BD-R, BD-RE.
|
||||
Libburn is an open-source library for reading, mastering and writing
|
||||
optical discs. For now this means only CD-R and CD-RW.
|
||||
|
||||
Our scope is currently Linux 2.4 and 2.6, or FreeBSD, or Solaris . For ports
|
||||
to other systems we would need : login on a development machine resp.
|
||||
an OS ithat is installable on an AMD 64-bit PC, advise from a system person
|
||||
about the equivalent of Linux sg or FreeBSD CAM, volunteers for testing of
|
||||
realistic use cases.
|
||||
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.
|
||||
|
||||
libburn is the library by which preformatted data get onto optical media.
|
||||
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.
|
||||
Our scope is currently Linux 2.4 and 2.6 and we will have a hard time to widen
|
||||
this for now, because of our history. The project could need advise from or
|
||||
membership of skilled kernel people and people who know how to talk CD/DVD
|
||||
drives into doing things.
|
||||
|
||||
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/BD 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.
|
||||
We do have a workable code base for burning data CDs, though. The burn API is
|
||||
quite comprehensively documented and can be used to build a presentable
|
||||
application.
|
||||
We do have a functional binary which emulates parts 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.
|
||||
|
||||
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.
|
||||
@subsection components The project components (list subject to growth, hopefully):
|
||||
|
||||
SONAME:
|
||||
libburn.so.4 (since 0.3.4, March 2007),
|
||||
- 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.
|
||||
|
||||
- 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

See cdrskin/README for more.
|
||||

- "test" is a collection of application gestures and examples given by the
|
||||
authors of the library features. The main API example of libburn
|
||||
is named test/libburner.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.

To build libburn and its subprojects it should be sufficient to go into

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.

|
||||
|
||||
libburner is a minimal demo application for the library libburn
|

|
||||
It can list the available devices, can burn to recordable CD, DVD, or BD,
|
||||
can blank a CD-RW or DVD-RW, and can format unformatted DVD-RW, BD-R, or BD-RE.

|
||||
To be read from *not mounted* CD via: afio -tvZ /dev/hdc
|
||||
Program tar would need a clean EOF which our padded CD cannot deliver.
|
||||
</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.

@section intro Introduction
|
||||
|
||||
Libburn is an open-source library for reading, mastering and writing
|
||||
optical discs. For now this means only CD-R and CD-RW.
|
||||
|
||||
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 and we will have a hard time to widen
|
||||
this for now, because of our history. The project could need advise from or
|
||||
membership of skilled kernel people and people who know how to talk CD/DVD
|
||||
drives into doing things.
|
||||
|
||||
We do have a workable code base for burning data CDs, though. The burn API is
|
||||
quite comprehensively documented and can be used to build a presentable
|
||||
application.
|
||||
We do have a functional binary which emulates parts 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.
|
||||
|
||||
- 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.
|
||||
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 main API example of libburn
|
||||
is named test/libburner.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 and
|
||||
can burn to CD-R or CD-RW.
|
||||
|
||||
It's main purpose, nevertheless, is to show you how to use libburn and also
|
||||
to serve the libburn 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.

||||

Burn a file to drive chosen by persistent address:
|
||||
test/libburner --drive /dev/hdc --burn_for_real my_image_file
|
||||
Blank a used CD-RW (is combinable with burning in one run):
|
||||
test/libburner --drive 0 --blank_fast
|
||||
Burn a compressed afio archive on-the-fly, pad up to 700 MB:
|
||||
( cd my_directory ; find . -print | afio -oZ - ) | \
|
||||
test/libburner --drive /dev/hdc --burn_for_real --stdin_size 734003200 -
|
||||
To be read from *not mounted* CD via:
|
||||
afio -tvZ /dev/hdc
|
||||
Program tar would need a clean EOF which our padded CD cannot deliver.

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 code module implements the production of RSPC parity bytes (P- and Q-
|
||||
parity) and the scrambling of raw CD-ROM sectors as specified in ECMA-130:
|
||||
http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-130.pdf
|
||||
|
||||
The following statements about Galois Fields have been learned mostly from
|
||||
http://www.cs.utk.edu/~plank/plank/papers/CS-96-332.pdf
|
||||
by James S. Plank after an e-mail exchange with Norbert Preining.
|
||||
|
||||
The output has been compared with the output of the old code of libburn
|
||||
which was labeled "borrowed HEAVILY from cdrdao" and claimed by Joerg
|
||||
Schilling to stem from code by Heiko Eissfeldt.
|
||||
|
||||
-------------------------------------------------------------------------
|
||||
Note: In this text, "^" denotes exponentiation and not the binary exor
|
||||
operation. Confusingly in the C code "^" is said exor.
|
||||
Note: This is not C1, C2 which is rather mentioned in ECMA-130 Annex C and
|
||||
always performed inside the drive.
|
||||
-------------------------------------------------------------------------
|
||||
|
||||
|
||||
RSPC resp. P- and Q-Parity
|
||||
|
||||
ECMA-130 Annex A prescribes to compute the parity bytes for P-columns and
|
||||
Q-diagonals by RSPC based on a Galois Field GF(2^8) with enumerating
|
||||
polynomials x^8+x^4+x^3+x^2+1 (i.e. 0x11d) and x^1 (i.e. 0x02).
|
||||
Bytes 12 to 2075 of a audio-sized sector get ordered in two byte words
|
||||
as 24 rows and 43 columns. Then this matrix is split into a LSB matrix
|
||||
and a MSB matrix of the same layout. Parity bytes are to be computed
|
||||
from these 8-bit values.
|
||||
2 P-bytes cover each column of 24 bytes. They get appended to the matrix
|
||||
as rows 24 and 25.
|
||||
2 Q-bytes cover each the 26 diagonals of the extended matrix.
|
||||
|
||||
Both parity byte pairs have to be computed so that extended rows or
|
||||
diagonals match this linear equation:
|
||||
H x V = (0,0)
|
||||
H is a 2-row matrix of size n matching the length of the V ectors
|
||||
[ 1 1 ... 1 1 ]
|
||||
[ x^(n-1) x^(n-2) x^1 1 ]
|
||||
Vp represents a P-row. It is a byte vector consisting of row bytes at
|
||||
position 0 to 23 and the two parity bytes which shall be determined
|
||||
at position 24 and 25. So Hp has 26 columns.
|
||||
Vq represents a Q-diagonal. It is a byte vector consisting of diagonal
|
||||
bytes at position 0 to 42 and the two parity bytes at position 43 and 44.
|
||||
So Hq has 45 columns. The Q-diagonals cover P-parity bytes.
|
||||
|
||||
By applying some high school algebra one gets the parity bytes b0, b1 of
|
||||
vector V = (n_payload_bytes, b0 , b1) as
|
||||
|
||||
b0 = ( H[n] * SUM(n_payload_bytes) - H[0..(n-1)] x n_payload_bytes )
|
||||
/ (H[n+1] - H[n])
|
||||
b1 = - SUM(n_payload_bytes) - b0
|
||||
|
||||
H[i] is the i-the element of the second row of matrix H. E.g. H[0] = x^(n-1)
|
||||
The result has to be computed by Galois field arithmetics. See below.
|
||||
|
||||
The P-parity bytes of each column get reunited as LSB and MSB of two words.
|
||||
word1 gets written to positions 1032 to 1074, word0 to 1075 to 1117.
|
||||
The Q-parity bytes of each diagonal get reunited too. word1 goes to 1118
|
||||
to 1143, word0 to 1144 to 1169.
|
||||
>>> I do not read this swap of word1 and word0 from ECMA-130 Annex A.
|
||||
>>> But the new output matches the old output only if it is done that way.
|
||||
>>> See correctness reservation below.
|
||||
|
||||
Algebra on Galois fields is the same as on Rational Numbers.
|
||||
But arithmetics is defined by operations on polynomials rather than the
|
||||
usual integer arithmetics on binary numbers.
|
||||
Addition and subtraction are identical with the binary exor operator.
|
||||
Multiplication and division would demand polynomial division, e.g. by the
|
||||
euclidian algorithm. The computing path over logarithms and powers follows
|
||||
algebra and allows to reduce the arithmetic task to table lookups, additions
|
||||
modulo 255, and exor operations. Note that the logarithms are natural
|
||||
numbers, not polynomials. They get added or subtracted by the usual addition
|
||||
(not by exor) and their polynomial power depends on their value modulo 255.
|
||||
|
||||
Needed are a logarithm table and a power table (or inverse logarithm table)
|
||||
for Galois Field GF(2^8) which will serve to perform the peculiar
|
||||
multiplication and division operation of Galois fields.
|
||||
|
||||
The power table is simply an enumeration of x^n accorting to
|
||||
GF-multiplication. It also serves as second line of matrix H for the parity
|
||||
equations:
|
||||
Hp[i] = gfpow[25-i] , i out of {0,..,25}
|
||||
Hq[i] = gfpow[44-i] , i out of {0,..,44}
|
||||
|
||||
The logarithm table is the inverse permutation of the power table.
|
||||
|
||||
Some simplifications apply to the implementation:
|
||||
In the world of Galois fields there is no difference between - and +.
|
||||
The term (H[n+1] - H[n]) is constant: 3.
|
||||
|
||||
-------------------------------------------------------------------------
|
||||
|
||||
|
||||
Scrambling
|
||||
|
||||
ECMA-130 Annex B prescribes to exor the byte stream of an audio-sized sector
|
||||
with a sequence of pseudo random bytes. It mentions polynomial x^15+x+1 and
|
||||
a 15-bit register.
|
||||
It shows a diagram of a Feedback Shift Register with 16 bit boxes, though.
|
||||
|
||||
Comparing this with explanations in
|
||||
http://www.newwaveinstruments.com/resources/articles/m_sequence_linear_feedback_shift_register_lfsr.htm
|
||||
one can recognize the diagram as a Fibonacci Implementation. But there seems
|
||||
really to be one bit box too many.
|
||||
|
||||
The difference of both lengths is expressed in function next_bit() by
|
||||
the constants 0x3fff,0x4000 for 15 bit versus 0x7fff,0x8000 for 16 bits.
|
||||
Comparing the output of both alternatives with the old scrambler output
|
||||
lets 15 bit win for now.
|
||||
|
||||
So the prescription is to start with 15 bit value 1, to use the lowest bit
|
||||
as output, to shift the bits down by one, to exor the output bit with the
|
||||
next lowest bit, and to put that exor result into bit 14 of the register.
|
||||
|
||||
-------------------------------------------------------------------------
|
||||
|
||||
|
||||
Correctness Reservation
|
||||
|
||||
In both cases, parity and scrambling, the goal for now is to replicate the
|
||||
output of the dismissed old lec.c by output which is based on published
|
||||
specs and own implementation code. Whether they comply to ECMA-130 is a
|
||||
different question which can only be answered by real test cases for
|
||||
raw CD recording.
|
||||
|
||||
Of course this implementation will be corrected so that it really complies
|
||||
to ECMA-130 as soon as evidence emerges that it does not yet.

libdax_msgs is designed to serve in libraries which want to offer their
|
||||
applications a way to control the output of library messages. It shall be
|
||||
incorporated by an owner, i.e. a software entity which encloses the code
|
||||
of the .c file.
|
||||
|
||||
Owner of libdax_msgs is libburn. A fully compatible variant named libiso_msgs
|
||||
is owned by libisofs and can get generated by a script of the libburn
|
||||
project: libburn/libdax_msgs_to_xyz_msgs.sh .
|
||||
|
||||
Reason: One cannot link two owners of the same variant together because
|
||||
both would offer the same functions to the linker. For that situation one
|
||||
has to create a compatible variant as it is done for libisofs.
|
||||
|
||||
Compatible variants may get plugged together by call combinations like
|
||||
burn_set_messenger(iso_get_messenger());
|
||||
A new variant would demand a _set_messenger() function if it has to work
|
||||
with libisofs. If only libburn is planned as link partner then a simple
|
||||
_get_messenger() does suffice.
|
||||
Take care to shutdown libburn before its provider of the *_msgs object
|
||||
gets shut down.

|

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_id_string() returns an id string of the SCSI transport adapter.
|
||||
It may be called before initialization but then may
|
||||
return only a preliminary id.
|
||||
|
||||
sg_initialize() performs global initialization of the SCSI transport
|
||||
adapter and eventually needed operating system
|
||||
facilities. Checks for compatibility of supporting
|
||||
software components.
|
||||
|
||||
sg_shutdown() performs global finalizations and releases golbally
|
||||
aquired resources.
|
||||
|
||||
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_dispose_drive() finalizes adapter specifics of struct burn_drive
|
||||
on destruction. Releases resources which were aquired
|
||||
underneath scsi_enumerate_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.
|
||||
|
||||
|
||||
burn_os_is_2k_seekrw() tells whether the given path leads to a file object
|
||||
that can be used in 2 kB granularity by lseek(2),
|
||||
read(2), and possibly write(2) if not read-only.
|
||||
E.g. a USB stick or a hard disk.
|
||||
|
||||
burn_os_stdio_capacity() estimates the emulated media space of stdio-drives.
|
||||
|
||||
burn_os_open_track_src() opens a disk file in a way that allows best
|
||||
throughput with file reading and/or SCSI write command
|
||||
transmission.
|
||||
|
||||
burn_os_alloc_buffer() allocates a memory area that is suitable for file
|
||||
descriptors issued by burn_os_open_track_src().
|
||||
The buffer size may be rounded up for alignment
|
||||
reasons.
|
||||

|

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: GNU libcdio , for X/Open compliant operating systems
|
||||
|
||||
|
||||
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_id_string() returns an id string of the SCSI transport adapter.
|
||||
It may be called before initialization but then may
|
||||
return only a preliminary id.
|
||||
|
||||
sg_initialize() performs global initialization of the SCSI transport
|
||||
adapter and eventually needed operating system
|
||||
facilities. Checks for compatibility of supporting
|
||||
software components.
|
||||
|
||||
sg_shutdown() performs global finalizations and releases golbally
|
||||
aquired resources.
|
||||
|
||||
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_dispose_drive() finalizes adapter specifics of struct burn_drive
|
||||
on destruction. Releases resources which were aquired
|
||||
underneath scsi_enumerate_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.
|
||||
|
||||
|
||||
burn_os_is_2k_seekrw() tells whether the given path leads to a file object
|
||||
that can be used in 2 kB granularity by lseek(2),
|
||||
read(2), and possibly write(2) if not read-only..
|
||||
E.g. a USB stick or a hard disk.
|
||||
|
||||
burn_os_stdio_capacity() estimates the emulated media space of stdio-drives.
|
||||
|
||||
burn_os_open_track_src() opens a disk file in a way that allows best
|
||||
throughput with file reading and/or SCSI write command
|
||||
transmission.
|
||||
|
||||
burn_os_alloc_buffer() allocates a memory area that is suitable for file
|
||||
descriptors issued by burn_os_open_track_src().
|
||||
The buffer size may be rounded up for alignment
|
||||
reasons.
|
||||
|
||||
burn_os_free_buffer() delete a buffer obtained by burn_os_alloc_buffer().
|
||||
|
||||
Porting hints are marked by the text "PORTING:".

|

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: Solaris uscsi, e.g. for SunOS 5.11
|
||||
|
||||
|
||||
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_id_string() returns an id string of the SCSI transport adapter.
|
||||
It may be called before initialization but then may
|
||||
return only a preliminary id.
|
||||
|
||||
sg_initialize() performs global initialization of the SCSI transport
|
||||
adapter and eventually needed operating system
|
||||
facilities. Checks for compatibility of supporting
|
||||
software components.
|
||||
|
||||
sg_shutdown() performs global finalizations and releases golbally
|
||||
aquired resources.
|
||||
|
||||
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_dispose_drive() finalizes adapter specifics of struct burn_drive
|
||||
on destruction. Releases resources which were aquired
|
||||
underneath scsi_enumerate_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.
|
||||
|
||||
|
||||
burn_os_is_2k_seekrw() tells whether the given path leads to a file object
|
||||
that can be used in 2 kB granularity by lseek(2),
|
||||
read(2), and possibly write(2) if not read-only..
|
||||
E.g. a USB stick or a hard disk.
|
||||
|
||||
burn_os_stdio_capacity() estimates the emulated media space of stdio-drives.
|
||||
|
||||
burn_os_open_track_src() opens a disk file in a way that allows best
|
||||
throughput with file reading and/or SCSI write command
|
||||
transmission.
|
||||
|
||||
burn_os_alloc_buffer() allocates a memory area that is suitable for file
|
||||
descriptors issued by burn_os_open_track_src().
|
||||
The buffer size may be rounded up for alignment
|
||||
reasons.
|
||||
|
||||
burn_os_free_buffer() delete a buffer obtained by burn_os_alloc_buffer().
|
||||
|
||||
