you to modify an ISO image or multisession disc, including file addition and
|
||||
removal, change of file names and attributes, etc
|
||||
Download, Build and Installation

||||
autotools of at least version 1.7. If you have download the code from the
|
||||
repository, first of all you need to execute
|
||||
|
||||
./autogen.sh
|
||||
|
||||
on toplevel dir to execute autotools.
|
||||
|
||||
Alternatively you may unpack a release tarball for which you do not need
|
||||
autotools installed. For the most recent release of libisofs see:
|
||||
http://libburnia-project.org/wiki/Releases
|
||||
|
||||
To build libisofs it should be sufficient to go into its toplevel directory
|
||||
and execute
|
||||
|
||||
./configure --prefix=/usr
|
||||
make
|
||||
|
||||
To make the libraries accessible for running resp. developing applications
|
||||
make install
|
||||
|
||||
On GNU/Linux it 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 .
|
||||
|
||||
By use of a version script, the libisofs.so library exposes no other function
|
||||
names but those of the API definitions in <libisofs/libisofs.h>.
|
||||
If -Wl,--version-script=... makes problems with the local compiler, then
|
||||
disable this encapsulation feature by
|
||||
./configure --disable-versioned-libs
|
||||
make clean ; make
|
||||
|
||||
The ./configure script checks for the availability of supporting libraries.
|
||||
If found, they will become mandatory for the emerging libisofs.so and all
|
||||
applications which use it. This dependency can be avoided by configure options
|
||||
--disable-libacl avoid use of ACL functions like acl_to_text()
|
||||
--disable-xattr avoid use of xattr functions like listxattr()
|
||||
--disable-zlib avoid use of zlib functions like compress2()
|
||||
|
||||
See INSTALL file for general options of ./configure.

libisofs is a library to create an ISO-9660 filesystem, supports extensions
|
||||
like RockRidge or Joliet, and introduces an own extension AAIP.
|
||||
It is a full featured ISO-9660 editor which composes and changes the directory
|
||||
tree of an ISO image. This tree and its newly imported data file contents get
|
||||
then written as independent single-session image or as add-on session for the
|
||||
image from where the tree was originally loaded.

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 only CD media and all single layer DVD media except DVD+R.
|
||||
|
||||
The project comprises of several more or less interdependent parts which
|
||||
together strive to be a usable foundation for application development.
|
||||
These are libraries, language bindings, and middleware binaries which emulate
|
||||
classical (and valuable) Linux tools.
|
||||
|
||||
Our scope is currently Linux 2.4 and 2.6 only. For ports to other systems
|
||||
we would need : login on a development machine resp. a live OS on CD or DVD,
|
||||
advise from a system person about the equivalent of Linux sg or FreeBSD CAM,
|
||||
volunteers for testing of realistic use cases.
|
||||
|
||||
We have a workable code base for burning CD and most single layer DVD.
|
||||
The burn API is quite comprehensively documented and can be used to build a
|
||||
presentable application.
|
||||
We have a functional binary which emulates parts of cdrecord in order to
|
||||
prove that usability, and in order to allow you to explore libburnia's scope
|
||||
by help of existing cdrecord frontends.
|
||||
|
||||
The project components (list subject to growth, hopefully):
|
||||
|
||||
- libburn is the library by which preformatted data get onto optical media.
|
||||
It uses either /dev/sgN (e.g. on kernel 2.4 with ide-scsi) or
|
||||
/dev/hdX (e.g. on kernel 2.6).
|
||||
libburn is the foundation of our cdrecord emulation. Its code is
|
||||
independent of cdrecord. Its DVD capabilities are learned from
|
||||
studying the code of dvd+rw-tools and MMC-5 specs. No code but only
|
||||
the pure SCSI knowledge has been taken from dvd+rw-tools, though.
|
||||
|
||||
- libisofs is the library to pack up hard disk files and directories into a
|
||||
ISO 9660 disk image. This may then be brought to media via libburn.
|
||||
libisofs is to be the foundation of our upcoming mkisofs emulation.
|
||||
|
||||
- cdrskin is a limited cdrecord compatibility wrapper for libburn.
|
||||
Cdrecord is a powerful GPL'ed burn program included in Joerg
|
||||
Schilling's cdrtools. cdrskin strives to be a second source for
|
||||
the services traditionally provided by cdrecord. Additionally it
|
||||
provides libburn's DVD capabilities, where only -sao is compatible
|
||||
with cdrecord.
|
||||
cdrskin does not contain any bytes copied from cdrecord's sources.
|
||||
Many bytes have been copied from the message output of cdrecord
|
||||
runs, though.
|
||||
See cdrskin/README and man cdrskin/cdrskin.1 for more.
|
||||
|
||||
- test is a collection of application gestures and examples given by the
|
||||
authors of the library features. The main API example for libburn
|
||||
is test/libburner.c .
|
||||
Explore these examples if you look for inspiration.
|
||||
|
||||
We plan to be a responsive upstream. Bear with us. We are still practicing.

Project history as far as known to me:
|
||||
|
||||
- Founded in 2002 as it seems. See mailing list archives
|
||||
http://lists.freedesktop.org/archives/libburn/
|
||||
The site of this founder team is reachable and offers download of a
|
||||
(somewhat outdated) tarball and from CVS :
|
||||
http://icculus.org/burn/
|
||||
Copyright holders and most probably founders:
|
||||
Derek Foreman and Ben Jansens.
|
||||
|
||||
- I came to using libburn in 2005. Founded the cdrskin project and submitted
|
||||
necessary patches which were accepted or implemented better. Except one
|
||||
remaining patch which prevented cdrskin from using vanilla libburn from CVS.
|
||||
The cdrskin project site is reachable and offers download of the heavily
|
||||
patched (elsewise outdated) tarball under the name cdrskin-0.1.2 :
|
||||
http://scdbackup.sourceforge.net/cdrskin_eng.html
|
||||
It has meanwhile moved to use vanilla libburn.pykix.org , though.
|
||||
Version 0.1.4 constitutes the first release of this kind.
|
||||
|
||||
- In July 2006 our team mate Mario Danic announced a revival of libburn
|
||||
which by about nearly everybody else was perceived as unfriendly fork.
|
||||
Derek Foreman four days later posted a message which expressed his
|
||||
discontent.
|
||||
The situation first caused me to publically regret it and then - after i
|
||||
got the opportunity to move in with cdrskin - gave me true reason to
|
||||
personally apologize to Derek Foreman, Ben Jansens and the contibutors at
|
||||
icculus.org/burn. Posted to both projects:
|
||||
http://lists.freedesktop.org/archives/libburn/2006-August/000446.html
|
||||
http://mailman-mail1.webfaction.com/pipermail/libburn-hackers/2006-August/000024.html
|
||||
|
||||
- Mid August 2006 project cdrskin established a branch office in
|
||||
libburn.pykix.org so that all maintainers of our tools have one single place
|
||||
to get the current (at least slightely) usable coordinated versions of
|
||||
everything.
|
||||
Project cdrskin will live forth independendly for a while but it is committed
|
||||
to stay in sync with libburn.pykix.org (or some successor, if ever).
|
||||
cdrskin is also committed to support icculus.org/burn if the pending fork
|
||||
is made reality by content changes in that project. It will cease to maintain
|
||||
a patched version of icculus.org/burn though. Precondition for a new
|
||||
release of cdrskin on base of icculus.org/burn would be the pending
|
||||
"whitelist patch" therefore.
|
||||
I would rather prefer if both projects find consense and merge, or at least
|
||||
cooperate. I have not given up hope totally, yet.
|
||||
I, personally, will honor any approach.
|
||||
|
||||
- 2nd September 2006 the decision is made to strive for a consolidation of
|
||||
copyright and a commitment to GPL in a reasonable and open minded way.
|
||||
This is to avoid long term problems with code of unknown origin and
|
||||
with finding consense among the not so clearly defined group of copyright
|
||||
claimers and -holders.
|
||||
libisofs is already claimed sole copyright Mario Danic.
|
||||
cdrskin and libburner are already claimed sole copyright Thomas Schmitt.
|
||||
Rewrites of other components will follow and concluded by claiming full
|
||||
copyright within the group of libburn.pykix.org-copyright holders.

||||

|
||||
|
||||
- 26th October 2006 feature freeze for cdrskin-0.2.4 based on libburn-0.2.3 .

||||
This version of cdrskin is much more cdrecord compatible in repect
|
||||

|
||||
|
||||
- 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.

EL Torito CD booting
|

for PC-BIOS x86, PowerPC, (old) Mac, EFI
|
||||
|
||||
Sources:
|
||||
El Torito, Bootable CD-ROM Format Specification, Version 1.0, 1995
|
||||
which refers to ECMA-119, the standard for ISO 9660 filesystems.
|
||||
libisofs/eltorito.[ch] by Vreixo Formoso.
|
||||
man mkisofs by Joerg Schilling.
|
||||
|
||||
|
||||
ECMA-119 prescribes that the first 32 kB of an ISO 9660 image are System Area
|
||||
with arbitrary content. This prescription is obeyed by PC-BIOS systems only
|
||||
if the ISO 9660 image is presented on CD, DVD or BD media.
|
||||
In this case the El Torito Boot record is the starting point of booting.
|
||||
|
||||
The Boot Record is a ECMA-119 Volume Descriptor which is eventually located
|
||||
at 2 kB block number 17 (decimal). Its content points to the location of the
|
||||
Boot Catalog.
|
||||
The format is described in part by ECMA-119 8.2 "Boot Record" and further
|
||||
specified by El Torito figure 7.

|
||||
|
||||
|
||||
The Boot Catalog lists the available boot images which may be prepared for
|
||||
multiple system architectures, called "platforms".
|
||||
It consists of one or more 2 kB blocks. The content is a sequence of fixed
|
||||
format entries, 32 bytes each.
|
||||
The entries are grouped in sections, which assign the entries to a particular
|
||||
system architecture. The booting system will then choose an entry from an
|
||||
appropriate section.

0 = "80x86" which is used for standard PCs with Intel x86 or compatible CPU
|
||||
1 = "PowerPC" (possibly for IBM machines with PowerPC CPU)
|

2 = "Mac" (possibly for Apple computers with MC68000 or PowerPC CPU)
|

Further in use by GRUB2 is:
|

0xef = EFI, a competitor resp. successor to PC-BIOS, possibly in use with
|
||||
Intel ia64 Itanium and possibly with newer Apple machines.
|

The boot image file content is mostly opaque to the ISO 9660 image generator.
|

Nevertheless there is a tradition named "Boot Info Table" which prescribes
|
||||
to write information into byte fields of the boot image file content.
|
||||
There are no general means known how a producer of ISO 9660 images could
|
||||
detect the need for Boot Info Table production.
|
||||
It rather needs a hint from the user who has to know whether the boot image
|
||||
expects a Boot Info Table.
|

The Boot Info Table begins at byte 8 of the boot image content.

MBR
|
||||
for PC-BIOS x86 from (pseudo-) hard disk
|
||||
|
||||
Sources:
|

|
||||
Mailing list conversations with H. Peter Anvin and Vladimir Serbinenko.
|
||||
|
||||
|
||||
The candidates for MBR booting will normally use El Torito rather than MBR
|
||||
if the ISO image is presented on CD, DVD, or BD media.
|
||||
The eventual MBR comes into effect it the image is on a media that is
|
||||
interpreted by the BIOS as some kind of hard disk. Usually real hard disks,
|
||||
floppy disks, USB sticks, memory cards.
|
||||
|
||||
An important part of an MBR is the DOS style partition table. It describes up
|
||||
to four primary partitions. There are two formats used for block address:
|
||||
Cylinder/Head/Sector (C/H/S) and Logical Block Address (LBA). Both are based
|
||||
on units of 512 bytes. So MBR_LBA = ISO_LBA * 4.
|
||||
|
||||
For C/H/S, the sector address is broken up into whole cylinders, remaining
|
||||
heads, and remaining sectors + 1. The nomenclature seems to stem from antique
|
||||
drum storage.
|
||||
There are two parameters, sectors_per_head and heads_per_cylinder which are not
|
||||
stored in the MBR. So it is more or less arbitray how to convert a LBA into
|
||||
a C/H/S address and vice versa. For maximum range of C/H/S addresses one
|
||||
may use sectors_per_head = 63 , heads_per_cylinder = 255.

|

By tradition the MBR itself and possibly more blocks are not claimed by any
|
||||
partition. But starting the first partition at a non-zero block address causes
|
||||
on Linux a partition device file (e.g. /dev/sdb1) which cannot be used to mount
|
||||
the ISO filesystem.
|
||||
|
||||
libisofs is able to produce a second set of trees and meta data which is
|
||||
suitable for being mounted at start block 16 (ISO) resp. 64 (MBR).
|
||||
See <libisofs/libisofs.h> for call iso_write_opts_set_part_offset()
|
||||
and http://libburnia-project.org/wiki/PartitionOffset for examples with

An isohybrid MBR directs the booting BIOS to an ISOLINUX boot image which
|
||||
is also the target of an El Torito boot catalog entry.
|

For that purpose one has to take an MBR template and has to set a few bytes

|

"[MBR templates] are available in the Syslinux build tree under the names:
|
||||
mbr/isohdp[fp]x*.bin
|
||||
The default probably should be mbr/isohdppx.bin, but it's ultimately up
|
||||
to the user.
|
||||
[...]
|
||||
Note: the filesystem type is largely arbitrary, in theory it can be any
|
||||
value other than 0x00, 0x05, 0x0f, 0x85, 0xee, or 0xef. 0x17 ("Windows
|
||||
IFS Hidden") seems safeish, some people believe 0x83 (Linux) is better.

scdbackup Checksum Tags
|
||||
|
||||
The session checksum tag does not occupy its whole block. So there is room to
|
||||
store a scdbackup stream checksum tag, which is an ancestor format of the tags
|
||||
described here. This feature allows scdbackup to omit its own checksum filter
|
||||
if using xorriso as ISO 9660 formatter program.
|
||||
Such a tag makes only sense if the session begins at LBA 0.
|
||||
|
||||
See scdbackup-*/README, appendix VERIFY for a specification.
|
||||
|
||||
Example of a scdbackup checksum tag:
|
||||
scdbackup_checksum_tag_v0.1 2456606865 61 2_2 B00109.143415 2456606865 485bbef110870c45754d7adcc844a72c c2355d5ea3c94d792ff5893dfe0d6d7b
|
||||
|
||||
The tag is located at byte position 2456606865, contains 61 bytes of scdbackup
|
||||
checksum record (the next four words):
|
||||
Name of the backup volume is "2_2".

|
||||
The size of the volume is 2456606865 bytes, which have a MD5 sum of

The old algorithm was clarified publicly by the following mail.

Changes towards the old algorithm:

- 512-byte LBA of boot image is extended to 64 bit (we stay with 32)

- check for a magic number is now gone

[me:]
|

> Currently i lack of blob and prescriptions.
|
||||
|
||||
The blobs are available in the Syslinux build tree under the names:
|
||||
|
||||
mbr/isohdp[fp]x*.bin
|
||||
|
||||
The default probably should be mbr/isohdppx.bin, but it's ultimately up
|
||||
to the user.
|
||||
|
||||
User definable parameters:
|
||||
|
||||
-> MBR ID (default random 32-bit number,
|
||||
or preserved from previous instance)
|
||||
-> Sector count (default 32, range 1-63)
|
||||
-> Head count (default 64, range 1-256)
|
||||
-> Partition offset (default 0, range 0-64)
|
||||
-> Partition number (default 1, range 1-4)
|
||||
-> Filesystem type (default 0x17, range 1-255)
|
||||
|
||||
Note: the filesystem type is largely arbitrary, in theory it can be any
|
||||
value other than 0x00, 0x05, 0x0f, 0x85, 0xee, or 0xef. 0x17 ("Windows
|
||||
IFS Hidden") seems safeish, some people believe 0x83 (Linux) is better.
|
||||
|
||||
Here is the prescriptions for how to install it:
|
||||
|
||||
All numbers are littleendian. "word" means 16 bits, "dword" means 32
|
||||
bits, "qword" means 64 bits.

c = 1023
|

h = head_count
|
||||
s = sector_count
|
||||

||||
s = s | ((c & 0x300) >> 2)
|
||||
c = c & 0xff

||||

||||

|
||||
write byte s
|
