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:

even better performance in such a situation. 64k can be made default at

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 removes some restrictions on operating
systems other than Linux and FreeBSD.
- Fri Jul 02 2010 Release 0.6.0.pl00 of libisoburn adds more options to the
mkisofs emulation of xorriso. It also fixes minor bugs and shortcommings.
- Wed Sep 15 2010 Version 0.6.36 of libisofs can produce ISO images which
bear a partiton 1 with non-zero start address. They can be mounted from
USB stick via the main device file (e.g. /dev/sdb) as well as via the
partition device file (e.g. /dev/sdb1).
- Fri Sep 17 2010 libburn-0.8.6 lifts the test reservation on DVD-R DL media.
- Sat Sep 18 2010 Release 0.6.2.pl00 of libisoburn introduces a partition
with non-zero offset for ISO 9660 images on USB sticks, improves mkisofs
emulation, and fixes a regression which existed since version 0.4.2.
- Wed Oct 20 2010 libburn-0.8.8 can report the used amount of BD spare blocks.
- Sat Oct 23 2010 Version 0.6.38 of libisofs can use libjte to produce jigdo
files along with the ISO image. Further filesystem images may be appended
as MBR partitions 1 to 4. The capability was added to produce boot blocks
for computers with MIPS CPU.
- Tue Oct 26 2010 Release 0.6.4.pl00 of libisoburn and xorriso makes use of
the new libisofs capabilities.
- Wed Dec 08 2010 libburn-0.9.0 fixes a regression with SCSI command logging.
- Fri Dec 10 2010 Version 0.6.40 of libisofs makes the prediction of the
emerging image size less expensive and is able to make images bootable
for SUN SPARC systems.
- Sun Dec 12 2010 Release 0.6.6.pl00 of libisoburn and xorriso can read ISO
images which were copied to a different start address than they were prepared
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
xorriso dialog mode.
- 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:
Fixes a few rarely occurring bugs that have been found during the last month.
- Sat Jun 18 2011 release 1.1.0:
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.

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.

It is optional wether a track size is reserved in advance or not. Eventually
this is done by 53h RESERVE TRACK, RMZ=ARSV=0. Reservation size should better
already be aligned to 32 KiB.

/* ts A91016 : libburn/ecma130ab.c is the replacement for old libburn/lec.c
Copyright 2009, Thomas Schmitt <scdbackup@gmx.net>, libburnia-project.org
Provided under GPL version 2 or later.
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.

A function parameter handle of NULL activates the built-in abort handler.
Depending on mode it may cancel all drive operations, wait for all drives

burn_drive_get_status() for waiting and performing exit(1).
If parameter handle may be NULL or a text that shall be used as prefix for
pacifier messages of burn_abort_pacifier(). Other than with an application
provided handler, the prefix char array does not have to be kept existing
until the eventual signal event.
Before version 0.7.8 only action 0 was available. I.e. the built-in handler
waited for the drives to become idle and then performed exit(1) directly.
But during burn_disc_write() onto real CD or DVD, FreeBSD 8.0 pauses the
other threads until the signal handler returns.
The new actions try to avoid this deadlock. It is advised to use action 3
at least during burn_disc_write(), burn_disc_erase(), burn_disc_format():
burn_set_signal_handling(text, NULL, 0x30);
and to call burn_is_aborting(0) when the drive is BURN_DRIVE_IDLE.

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

underneath scsi_enumerate_drives().

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

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

Before you can do anything, you have to initialize libburn by
burn_initialize()
and provide some signal and abort handling, e.g. by the builtin handler, by
burn_set_signal_handling("libburner : ", NULL, 0x0)
as it is done in main() at the end of this file.
Then you aquire a drive in an appropriate way conforming to the API. The twoi
main approaches are shown here in application functions:
burn_set_signal_handling()
as it is done in main() at the end of this file. Then you aquire a
drive in an appropriate way conforming to the API. The two main
approaches are shown here in application functions:
libburner_aquire_by_adr() demonstrates usage as of cdrecord traditions
libburner_aquire_by_driveno() demonstrates a scan-and-choose approach
With that aquired drive you can blank a CD-RW or DVD-RW as shown in
With that aquired drive you can blank a CD-RW
libburner_blank_disc()
or you can format a DVD-RW to profile "Restricted Overwrite" (needed once)
or an unused BD to default size with spare blocks
libburner_format()
With the aquired drive you can burn to CD, DVD, BD. See
With the aquired drive you can burn to CD, DVD, BD
libburner_payload()
These three functions switch temporarily to a non-fatal signal handler
while they are waiting for the drive to become idle again:
burn_set_signal_handling("libburner : ", NULL, 0x30)
After the waiting loop ended, they check for eventual abort events by
burn_is_aborting(0)
The 0x30 handler will eventually execute
burn_abort()
but not wait for the drive to become idle and not call exit().
This is needed because the worker threads might block as long as the signal
handler has not returned. The 0x0 handler would wait for them to finish.
Take this into respect when implementing own signal handlers.
When everything is done, main() releases the drive and shuts down libburn:
burn_drive_release();
burn_finish()
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
autotools generated build system.

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.
