Build and Installation
|
||||
|
||||
From tarball
|
||||
Our build system is based on autotools. For preparing the build of a SVN
|
||||
snapshot you will need autotools of at least version 1.7.
|
||||
Check out from SVN by
|
||||
svn co http://svn.libburnia-project.org/libburn/trunk libburn
|
||||
go into directory libburn and apply autotools by
|
||||
./bootstrap
|
||||
|
||||
Obtain libburn-0.8.4.pl00.tar.gz, take it to a directory of your choice and do:
|
||||
Alternatively you may unpack a release tarball for which you do not need
|
||||
autotools installed.
|
||||
|
||||
tar xzf libburn-0.8.4.pl00.tar.gz
|
||||
cd libburn-0.8.4
|
||||
To build a libburnia-project.org subproject it should be sufficient to go
|
||||
into its toplevel directory (here: "libburn") and execute
|
||||
./configure --prefix=/usr
|
||||
make
|
||||
|
||||
To make libburn accessible for running resp. application development,
|
||||
and to install the cdrecord compatibility binary cdrskin, do
|
||||
(as Superuser):
|
||||
|
||||
and to install the cdrecord compatibility binary cdrskin, do:
|
||||
make install
|
||||
|
||||
This procedure installs libburn.so.4 and cdrskin depending on it.
|
||||
|
||||
Above procedure installs cdrskin depending on libburn.so.4 .
|
||||
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
|
||||
./bootstrap
|
||||
./configure --prefix=/usr
|
||||
make
|
||||
make install
|
||||
|
||||
Warning: The trunk might contain experimental features which might not
|
||||
persist until next release.
|
||||
|
||||
|
||||
Special ./configure options
|
||||
|
||||
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
|
||||
|
||||
Make sure to re-compile all source files after running ./configure
|

on FreeBSD with ATAPI/CAM enabled in the kernel (see man atapicam),

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.
|
||||
|
||||
- 2nd Jan 2009 libburn-0.6.0 allows to format BD-R and to write to either
|
||||
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:".
|
||||
|
||||
- 20th Feb 2009 libburn-0.6.2 source release now compiles out of the box
|
||||
on FreeBSD.
|
||||
|
||||
- 28 Feb 2009 libisofs-0.6.14 can record ACLs and Extended Attributes xattr
|
||||
in its ISO images.
|
||||
|
||||
- 01 Mar 2009 libisoburn-0.3.4. xorriso makes use of the ACL and xattr
|
||||
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.
|
||||
Built-in filters allow compression to formats gzip and zisofs. External
|
||||
filter processes allow arbitrary data conversions like encryption.
|
||||
|
||||
- 19 Apr 2009 libisoburn-0.3.8 makes use of the new libisofs capability to
|
||||
perform content filtering of data files.
|
||||
|
||||
- 08 May 2009 libburn-0.6.6 fixes a bug with aborting on broken output pipe
|
||||
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.
|
||||
|
||||
- 14 Jul 2009 libburn-0.6.8 fixes bugs and shortcommings with old MMC-1 drives
|
||||
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
|
||||
data loss in older sessions if xorriso was used underneath growisofs.
|
||||
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,
|
||||
provides throughput enhancements with hampered busses on Linux, and new
|
||||
API calls to log SCSI commands and to control the libburn fifo.
|
||||
|
||||
- 09 Dec 2009 libisoburn-0.4.6 allows performance tuning of output to DVD
|
||||
drives or disk files.
|
||||
|
||||
- 26 Dec 2009 libburn-0.7.4.pl01 fixes the release tarball which was lacking
|
||||
the files of the generic system adapter for X/Open.
|
||||
|
||||
- 29 Dec 2009 Our project received a donation for purchasing a fine small
|
||||
computer which shall serve as OS farm for development and support.
|
||||
|
||||
- 20 Jan 2010 Version 0.6.26 of libisofs fixes minor bugs and shall enhance
|
||||
portability.
|
||||
|
||||
- 22 Jan 2010 libburn-0.7.6 has an improved system adapter for FreeBSD,
|
||||
fixes bugs about the generic X/Open system adapter, and allows to use
|
||||
libcdio >= 0.83 as SCSI transport facility.
|
||||
|
||||
- 10 Feb 2010 libisofs-0.6.28 fixes a regression about bootable images which
|
||||
was introduced by version 0.6.22 in August 2009.
|
||||
|
||||
- 23 Feb 2010 libisoburn-0.5.0 marks the transition of the xorriso standalone
|
||||
version to an official GNU project. The name changed to "GNU xorriso" and its
|
||||
license is now GPLv3+.
|
||||
The licenses of libburnia libraries and applications are not affected by
|
||||
this change.
|
||||
|
||||
- 10 Mar 2010 libburn-0.7.8 fixes bugs and improves the built-in abort handler
|
||||
on FreeBSD.
|
||||
|
||||
- 30 Mar 2010 Release 0.5.2 of libisoburn provides xorriso documentation in
|
||||
GNU Texinfo format with embedded extra data to derive a full man page.
|
||||
|
||||
- 09 Apr 2010 libburn-0.8.0 now works with ahci driver on FreeBSD 8-STABLE.
|
||||
|
||||
- 03 May 2010 Version 0.6.32 of libisofs is able to create ISO images with
|
||||
multiple boot images. All boot catalog parameters described in El-Torito
|
||||
specs can be set and inquired. This allows to use GRUB boot images for EFI.
|
||||
|
||||
- 04 May 2010 Release 0.5.6.pl00 of libisoburn makes use of the new libisofs
|
||||
capabilities about boot images.
|
||||
|
||||
- 11 Jun 2010 libburn-0.8.2 now works on Solaris.
|
||||
|
||||
- 14 Jun 2010 By release 0.5.8.pl00 of libisoburn, xorriso becomes a public C
|
||||
language API of libisoburn. The emulations of mkisofs and cdrecord have
|
||||
been enhanced.
|
||||
|
||||
- Tue Jun 29 2010 Version 0.6.34 of libisofs provides new features about
|
||||
hiding file names from directory trees.
|
||||
|
||||
- Wed Jun 30 2010 libburn-0.8.4 provides small improvements with system
|
||||
adapters for libcdio and generic POSIX systems.

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

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

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

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.

------------------------------------------------------------------------------
|

|

We, the copyright holders, agree on the interpretation that

dynamical linking of our libraries constitutes "use of" and

not "derivation from" our work in the sense of GPL, provided

those libraries are compiled from our unaltered code.
|

|

Thus you may link our libraries dynamically with applications
|

which are not under GPL. You may distribute our libraries and

application tools in binary form, if you fulfill the usual
|
||||
condition of GPL to offer a copy of the source code -altered
|

or unaltered- under GPL.

We ask you politely to use our work in open source spirit

and with the due reference to the entire open source community.

|

If there should really arise the case where above clarification
|
||||
does not suffice to fulfill a clear and neat request in open source

||||
spirit that would otherwise be declined for mere formal reasons,
|
||||
only in that case we will duely consider to issue a special license
|
||||
covering only that special case.
|
||||
It is the open source idea of responsible freedom which will be
|
||||
decisive and you will have to prove that you exhausted all own
|
||||
means to qualify for GPL.
|
||||
|
||||
For now we are firmly committed to maintain one single license: GPL.

@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.
|
||||
optical discs.
|
||||
For now this means CD-R, CD-RW, DVD-RAM, DVD+RW, DVD+R, DVD+R/DL, DVD-RW,
|
||||
DVD-R, BD-R, BD-RE.
|
||||
DVD-R, BD-RE.
|
||||
|
||||
Not supported yet are DVD-R/DL. Testers wanted.
|
||||
Not supported yet are DVD-R/DL, HD-DVD, BD-R (blue ray). Testers for
|
||||
DVD-R/DL are wanted, though. BD-R programming efforts would be made
|
||||
if an interested tester contacts us.
|
||||
|
||||
Our scope is currently Linux 2.4 and 2.6, or FreeBSD . For ports to other
|
||||
systems we would need : login on a development machine resp. a live OS on CD
|
||||
or DVD, advise from a system person about the equivalent of Linux sg or FreeBSD
|
||||
CAM, volunteers for testing of realistic use cases.
|
||||
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.

|
||||
|
||||
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 have a well tested code base for burning data and audio CDs and many DVD
|
||||
types. The burn API is quite comprehensively documented and can be used to
|
||||
build a presentable application.
|
||||
We have a functional binary which emulates the core use cases of cdrecord in
|
||||
order to prove that usability, and in order to allow you to explore libburn's
|
||||
scope by help of existing cdrecord frontends.
|
||||
|
||||
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.
|
||||
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.

||||

||||
SONAME:
|
||||
@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/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.
|
||||
|
||||
- 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.
|
||||
|
||||
- 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.
|
||||
|
||||
- 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
|
||||

|
||||

|
||||
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 deletion, renaming, and attribute
|
||||
changing. An incremental backup feature is provided.
|
||||
See xorriso/README for more
|
||||
|
||||
- "test" is a collection of application gestures and examples given by the
|
||||
authors of the library features. The burn API example of libburn
|
||||
is named test/libburner.c . The API for media information inquiry is
|
||||
demonstrated in test/telltoc.c .
|
||||
Explore these examples if you look for inspiration.
|
||||
|
||||
We 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.

ISO 9660 multi-session emulation on overwriteable media :
|
||||
|
||||
Overwriteable media provide a single overwriteable track which may grow up to
|
||||
the full media capacity. There is no builtin table-of-content which records
|
||||
the history of write sessions.
|
||||
mount -t iso9660 will use sbsector=0 as default.
|
||||
The term "superblock" shall depict the first 64 KiB after the sbsector address.
|
||||
|
||||
ISO 9660 multi-session depends on typical TOC information in two ways:
|
||||
It needs the superblock address MSC1 of the most recently recorded session and
|
||||
it needs the Next Writeable Address NWA for which to prepare the adress offset.
|
||||
|
||||
The following is learned from growisofs and from ECMA-119:
|
||||
http://www.ecma-international.org/publications/files/ECMA-ST/Ecma-119.pdf
|
||||
|
||||
ISO 9660 filesystems provide information about the number of sectors which
|
||||
is also the lowest unused block address and thus a suitable NWA.
|
||||
This block address is stored in the Primary Volume Descriptor which is supposed
|
||||
to be stored in block 16 (eventually relative to MSC1).
|
||||
The bytes 0 to 5 of a PVD block are
|
||||
0x01 'C' 'D' '0' '0' '1'
|
||||
The sector count can then be read from byte 80 to 83
|
||||
sectors= pvd[80] | (pvd[81] << 8) | (pvd[82] << 16) | (pvd[83] << 24);
|
||||
(Ecma-119.pdf 8.4)
|
||||
To support CD, DVD and BD media alike, it is advisable to round the NWA
|
||||
to the next multiple of 32 (= 64 KiB).
|
||||
|
||||
So one can use 0 as MSC1 and prepare a new ISO session for the computed NWA.
|
||||
After writing the session it is necessary to patch the PVD at LBA 16.
|
||||
The minimal change would be to update the number of image sectors.
|
||||
It is stored in both notations LSB and MSB:
|
||||
for(i= 0; i < 4; i++)
|
||||
pvd[87 - i]= pvd[80 + i]= (sectors >> (8 * i)) & 0xff;
|
||||
|
||||
cdrskin --grow_overwriteable_iso not only patches the sector fields of the
|
||||
PVD block but also the blocks up to LBA 31 which begin with
|
||||
0xff 'C' 'D' '0' '0' '1'
|
||||
libisoburn submits 64 KiB data buffer to libisofs before image generation and
|
||||
afterwards writes these 64 KiB as new superblock to LBA 0.
|
||||
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||
ISO 9660 based TOC emulation on overwriteable media :
|
||||
|
||||
Above method of multi-session emulation yields a single session image after
|
||||
each add-on session. No reliable session history can be read because the
|
||||
sector size of the existing session gets overwritten by the new one.
|
||||
A TOC with session history is nevertheless desirable with incremental backups
|
||||
in order to access older backup states by mounting older superblocks at the
|
||||
start addresses of older sessions.
|
||||
|
||||
All usual ISO 9660 formatter programs write a complete superblock to the
|
||||
start of each session.
|
||||
With a uniform NWA rounding rule it is possible to compute the address of
|
||||
superblock N+1 as the NWA after session N. The only problem is N=1
|
||||
because it gets overwritten by later sessions.
|
||||
|
||||
libisoburn preserves the information of session 1 by writing the first session
|
||||
to LBA 32 rather than LBA 0. Afterwards it writes the overall superblock to
|
||||
LBA 0 (up to 31).
|
||||
So with all further add-on sessions the superblock at LBA 0 will enclose the
|
||||
overall image, while the superblocks of the sessions form a chain beginning
|
||||
at LBA 32. Each session superblock points to the next one by its sector count
|
||||
rounded up to 32. The chain end is marked by the overall image size.
|
||||
This chain gives the start addresses of sessions. The sector count minus start
|
||||
address gives the size of a particular session. ECMA-119 explains how to
|
||||
retrieve more info from the PVD (e.g. the volume id).
|
||||
|
||||
See also the multi-session example in libisofs/doc/checksums.txt.

|
||||
SRM Formatting:
|
||||
|
||||
Despite being write-once media BD-R can optionally carry some formatting.
|
||||
|
||||
SRM has a disc structure model with tracks and sessions.
|
||||
Several tracks may be open at the same time, each having its own NWA.
|
||||
(mmc5r03c.pdf 4.5.3.5.2.2)
|
||||
This structure is formatted onto blank media automatically as soon as the
|
||||
first serious write attempt occurs.
|
||||
(mmc5r03c.pdf 4.5.3.5)
|
||||
Before such a write attempt, blank media may be explicitely formatted with
|
||||
spares, which provide defect management.
|
||||
(mmc5r03c.pdf 4.5.3.5.3)
|
||||
Tracks get created from other tracks via RESERVE TRACK splitting.
|
||||
(mmc5r03c.pdf 4.5.3.5.2.5)
|
||||
|
||||
On top of defect management there may be Pseudo-OverWrite SRM+POW, a costly
|
||||
way to write several times to the same LBA. See below.
|
||||
Fully sequential states are called SRM-POW.
|
||||
(mmc5r03c.pdf 4.5.3.5.4)
|
||||
|
||||
Explicite formatting is done by 04h FORMAT UNIT. Its data payload consists
|
||||
of a Format List Header and a Format Descriptor. It is advisable to set
|
||||
the Immed bit and the FOV bit in header byte number 1. The descriptor should
|
||||
be a copy of a descriptor from 23h READ FORMAT CAPACITIES but the size may be
|
||||
adjusted within a certain range.
|
||||
(mmc5r03c.pdf 6.5, 6.5.3.2, 6.5.3.3)
|
||||
|
||||
Format type 00h creates SRM layouts with a default number of spares (or
|
||||
eventually RRM) chosen by the format sub-type:
|
||||
00b = SRM with support for POW
|
||||
01b = SRM without POW (but with some spares for defect management)
|
||||
10b = (RRM)
|
||||
(mmc5r03c.pdf 6.5.4.2.1.6)
|
||||
|
||||
Format type 32h uses the same sub-types but allows to allocate non-default
|
||||
amounts of spares. Similar to BD-RE format 31h, three format descriptors are
|
||||
offered: #1: default size, #2: maximum spare area, #3: minimal spare.
|
||||
The size may be chosen within that range.
|
||||
|
||||
The sense behind the Type Dependent Parameters is obscure
|
||||
to me. Best will be to set ISA_V and TDMA_V to 0.

||||

-------------------------------------------------------------------------------
|
||||
Writing a session in SRM:
|
||||
|
||||
The procedure and constraints for writing BD-R SRM-POW are very similar to
|
||||
DVD+R. libburn flatly re-uses its DVD+R code except the Close Function for
|
||||
finalizing a disc.
|
||||
|
||||
In short:
|
||||
If all written sessions are closed, then there is exactly one NWA.
|
||||
In the beginning there is an empty session and track. A new track can be
|
||||
written either with pre-announced size (by RESERVE TRACK) or open-end by
|
||||
simply starting to write to the NWA. When done the track gets closed by
|
||||
close function 001b. Then either session or disc gets closed depending on
|
||||
the Close Function used:
|
||||
- Close Function 010b closes the session and keeps the media appendable
|
||||
(same as with DVD+R)
|
||||
- Close Function 110b finalizes the media and makes it read-only.
|
||||
(differs from libburn DVD+R procedure which uses 101b)
|
||||
|
||||
-------------------------------------------------------------------------------
|
||||
Pseudo-OverWrite POW: (no used yet by libburn)
|
||||
|
||||
This enhancement of SRM emulates overwriting of existing data blocks.
|
||||
(mmc5r03c.pdf 4.5.3.5.4)
|
||||
|
||||
POW establishes a virtual vLBA space on top of the real address space rLBA.
|
||||
All read and write commands deal with vLBA. It seems that track NWAs are
|
||||
assumed to be identical in vLBA space and in rLBA space.
|
||||
It is not clear whether one may write to vLBA blocks which are neither written
|
||||
yet nor at one of the track NWAs. Probably not, or else one could make NWAs run
|
||||
into vLBAs which are associated with older rLBAs.
|
||||
|
||||
Replacing invalidated blocks consumes addresses in rLBA space at the NWA of
|
||||
some track. I.e. no spares are consumed by POW. Nevertheless it is costly by
|
||||
a special map called Orphanage. It covers rLBA which have been consumed
|
||||
by differing vLBAs. It never shrinks and can grow with each write to remapped
|
||||
addresses.
|
||||
To avoid heavy Orphanage growth it is advised to write mostly to vLBA which
|
||||
still coincide with their rLBA. E.g. those addresses which have neither been
|
||||
written as rLBA nor as vLBA yet. So one should begin the vLBA of new sessions
|
||||
at the NWA of a sufficiently sized track.

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.

|

|

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().
|
||||
|
||||
Porting hints are marked by the text "PORTING:".

|

Simplified data transmission for DVD. libburn via GNU/Linux USB is 30 %
|
||||
slower than growisofs or cdrecord when transmitting 32 KB chunks.
|
||||
With 64 KB chunks it is 20% faster than the competitors.
|
||||
No heavy CPU load is visible but there might be subtle race conditions in
|
||||
the USB driver which work better with shorter time gaps between WRITE
|
||||
commands.
|
||||
|
||||
Insight: It is actually about the interference of track source reading
|
||||
with SCSI writing via USB. growisofs reads with O_DIRECT into a
|
||||
mmap()ed buffer. When doing the same, libburn with 32 KB chunks
|
||||
reaches similar write speed.
|
||||
On the other hand, 64 KB chunks are 20% faster than that and
|
||||
are not improved by reading O_DIRECT.
|
||||
|
||||
O_DIRECT is a property of the input fd of struct burn_source.
|
||||
It can only be done with properly aligned memory and with aligned
|
||||
read size. Alignment size is file system system specific.
|
||||
System call
|
||||
mmap(NULL, (size_t) buffer_size, PROT_READ | PROT_WRITE,
|
||||
MAP_SHARED | MAP_ANONYMOUS, -1, (off_t) 0);
|
||||
is supposed to allocate a properly aligned buffer.
|
||||
64 KB is supposed to be a safe size.
|
||||
Actually mmap() seems to be the main cause for a positive effect
|
||||
of O_DIRECT.
|
||||
|
||||
This simplified transmission function did not bring visible benefit.
|
||||
So for now it is not worth to teach it all applicable details of old
|
||||
CD sector oriented transmission.

FreeBSD does not work well with the convenient synchronous signal handler. So

the waiting loops for blanking, formatting, and writing use the asynchronous

mode of the libburn signal handler. It will not shutdown the library and

abort the program, but rather tell the ongoing drive operation to stop as

soon as possible. After the loops and at the end of the program there is a
|
||||
call to determine whether an abort happened:
|
||||
burn_is_aborting()
|

|
||||
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 library by 64 bit integers
|
||||
where libburn/libburn.h prescribes off_t.

This program gets fed with appropriate settings externally by libburn's

Clarification in my name and in the name of Mario Danic, copyright holder

on toplevel of libburnia. To be fully in effect after the remaining other
|

copyrighted code has been replaced by ours and by copyright-free contributions
|

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