+
+- 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

+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.

+   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().

+
+   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

+    #define _FILE_OFFSET_BITS 64

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

-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.
