Fix compilation on Arch Linux

`kIOMasterPortDefault` is deprecated since macOS 12.0.
One alternative is to use named constant `kIOMainPortDefault` which is
not available before macOS 12.0.

Both named constants are just an alias for `NULL`, so it is simpler to
use it directly instead.

                             Preamble
 
-  The licenses for most software are designed to take away your
-freedom to share and change it.  By contrast, the GNU General Public
-License is intended to guarantee your freedom to share and change free
-software--to make sure the software is free for all its users.  This
-General Public License applies to most of the Free Software
-Foundation's software and to any other program whose authors commit to
-using it.  (Some other Free Software Foundation software is covered by
-the GNU Library General Public License instead.)  You can apply it to
+  The GNU General Public License is a free, copyleft license for
+software and other kinds of works.
+
+  The licenses for most software and other practical works are designed
+to take away your freedom to share and change the works.  By contrast,
+the GNU General Public License is intended to guarantee your freedom to
+share and change all versions of a program--to make sure it remains free
+software for all its users.  We, the Free Software Foundation, use the
+GNU General Public License for most of our software; it applies also to
+any other work released this way by its authors.  You can apply it to
 your programs, too.
 
   When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
-this service if you wish), that you receive source code or can get it
-if you want it, that you can change the software or use pieces of it
-in new free programs; and that you know you can do these things.
+them if you wish), that you receive source code or can get it if you
+want it, that you can change the software or use pieces of it in new
+free programs, and that you know you can do these things.
 
-  To protect your rights, we need to make restrictions that forbid
-anyone to deny you these rights or to ask you to surrender the rights.
-These restrictions translate to certain responsibilities for you if you
-distribute copies of the software, or if you modify it.
+  To protect your rights, we need to prevent others from denying you
+these rights or asking you to surrender the rights.  Therefore, you have
+certain responsibilities if you distribute copies of the software, or if
+you modify it: responsibilities to respect the freedom of others.
 
   For example, if you distribute copies of such a program, whether
-gratis or for a fee, you must give the recipients all the rights that
-you have.  You must make sure that they, too, receive or can get the
-source code.  And you must show them these terms so they know their
-rights.
+gratis or for a fee, you must pass on to the recipients the same
+freedoms that you received.  You must make sure that they, too, receive
+or can get the source code.  And you must show them these terms so they
+know their rights.
 
-  We protect your rights with two steps: (1) copyright the software, and
-(2) offer you this license which gives you legal permission to copy,
-distribute and/or modify the software.
+  Developers that use the GNU GPL protect your rights with two steps:
+(1) assert copyright on the software, and (2) offer you this License
+giving you legal permission to copy, distribute and/or modify it.
 
-  Also, for each author's protection and ours, we want to make certain
-that everyone understands that there is no warranty for this free
-software.  If the software is modified by someone else and passed on, we
-want its recipients to know that what they have is not the original, so
-that any problems introduced by others will not reflect on the original
-authors' reputations.
+  For the developers' and authors' protection, the GPL clearly explains
+that there is no warranty for this free software.  For both users' and
+authors' sake, the GPL requires that modified versions be marked as
+changed, so that their problems will not be attributed erroneously to
+authors of previous versions.
 
-  Finally, any free program is threatened constantly by software
-patents.  We wish to avoid the danger that redistributors of a free
-program will individually obtain patent licenses, in effect making the
-program proprietary.  To prevent this, we have made it clear that any
-patent must be licensed for everyone's free use or not licensed at all.
+  Some devices are designed to deny users access to install or run
+modified versions of the software inside them, although the manufacturer
+can do so.  This is fundamentally incompatible with the aim of
+protecting users' freedom to change the software.  The systematic
+pattern of such abuse occurs in the area of products for individuals to
+use, which is precisely where it is most unacceptable.  Therefore, we
+have designed this version of the GPL to prohibit the practice for those
+products.  If such problems arise substantially in other domains, we
+stand ready to extend this provision to those domains in future versions
+of the GPL, as needed to protect the freedom of users.
+
+  Finally, every program is threatened constantly by software patents.
+States should not allow patents to restrict development and use of
+software on general-purpose computers, but in those that do, we wish to
+avoid the special danger that patents applied to a free program could
+make it effectively proprietary.  To prevent this, the GPL assures that
+patents cannot be used to render the program non-free.
 
   The precise terms and conditions for copying, distribution and
 modification follow.
-
-                    GNU GENERAL PUBLIC LICENSE
-   TERMS AND CONDITIONS FOR COPYING, DISTRIBUTION AND MODIFICATION
 
-  0. This License applies to any program or other work which contains
-a notice placed by the copyright holder saying it may be distributed
-under the terms of this General Public License.  The "Program", below,
-refers to any such program or work, and a "work based on the Program"
-means either the Program or any derivative work under copyright law:
-that is to say, a work containing the Program or a portion of it,
-either verbatim or with modifications and/or translated into another
-language.  (Hereinafter, translation is included without limitation in
-the term "modification".)  Each licensee is addressed as "you".
+                       TERMS AND CONDITIONS
 
-Activities other than copying, distribution and modification are not
-covered by this License; they are outside its scope.  The act of
-running the Program is not restricted, and the output from the Program
-is covered only if its contents constitute a work based on the
-Program (independent of having been made by running the Program).
-Whether that is true depends on what the Program does.
+  0. Definitions.
 
-  1. You may copy and distribute verbatim copies of the Program's
-source code as you receive it, in any medium, provided that you
-conspicuously and appropriately publish on each copy an appropriate
-copyright notice and disclaimer of warranty; keep intact all the
-notices that refer to this License and to the absence of any warranty;
-and give any other recipients of the Program a copy of this License
-along with the Program.
+  "This License" refers to version 3 of the GNU General Public License.
 
-You may charge a fee for the physical act of transferring a copy, and
-you may at your option offer warranty protection in exchange for a fee.
+  "Copyright" also means copyright-like laws that apply to other kinds of
+works, such as semiconductor masks.
 
-  2. You may modify your copy or copies of the Program or any portion
-of it, thus forming a work based on the Program, and copy and
-distribute such modifications or work under the terms of Section 1
-above, provided that you also meet all of these conditions:
+  "The Program" refers to any copyrightable work licensed under this
+License.  Each licensee is addressed as "you".  "Licensees" and
+"recipients" may be individuals or organizations.
 
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
+  To "modify" a work means to copy from or adapt all or part of the work
+in a fashion requiring copyright permission, other than the making of an
+exact copy.  The resulting work is called a "modified version" of the
+earlier work or a work "based on" the earlier work.
 
-    b) You must cause any work that you distribute or publish, that in
-    whole or in part contains or is derived from the Program or any
-    part thereof, to be licensed as a whole at no charge to all third
-    parties under the terms of this License.
+  A "covered work" means either the unmodified Program or a work based
+on the Program.
 
-    c) If the modified program normally reads commands interactively
-    when run, you must cause it, when started running for such
-    interactive use in the most ordinary way, to print or display an
-    announcement including an appropriate copyright notice and a
-    notice that there is no warranty (or else, saying that you provide
-    a warranty) and that users may redistribute the program under
-    these conditions, and telling the user how to view a copy of this
-    License.  (Exception: if the Program itself is interactive but
-    does not normally print such an announcement, your work based on
-    the Program is not required to print an announcement.)
-
-These requirements apply to the modified work as a whole.  If
-identifiable sections of that work are not derived from the Program,
-and can be reasonably considered independent and separate works in
-themselves, then this License, and its terms, do not apply to those
-sections when you distribute them as separate works.  But when you
-distribute the same sections as part of a whole which is a work based
-on the Program, the distribution of the whole must be on the terms of
-this License, whose permissions for other licensees extend to the
-entire whole, and thus to each and every part regardless of who wrote it.
+  To "propagate" a work means to do anything with it that, without
+permission, would make you directly or secondarily liable for
+infringement under applicable copyright law, except executing it on a
+computer or modifying a private copy.  Propagation includes copying,
+distribution (with or without modification), making available to the
+public, and in some countries other activities as well.
 
-Thus, it is not the intent of this section to claim rights or contest
-your rights to work written entirely by you; rather, the intent is to
-exercise the right to control the distribution of derivative or
-collective works based on the Program.
+  To "convey" a work means any kind of propagation that enables other
+parties to make or receive copies.  Mere interaction with a user through
+a computer network, with no transfer of a copy, is not conveying.
 
-In addition, mere aggregation of another work not based on the Program
-with the Program (or with a work based on the Program) on a volume of
-a storage or distribution medium does not bring the other work under
-the scope of this License.
+  An interactive user interface displays "Appropriate Legal Notices"
+to the extent that it includes a convenient and prominently visible
+feature that (1) displays an appropriate copyright notice, and (2)
+tells the user that there is no warranty for the work (except to the
+extent that warranties are provided), that licensees may convey the
+work under this License, and how to view a copy of this License.  If
+the interface presents a list of user commands or options, such as a
+menu, a prominent item in the list meets this criterion.
 
-  3. You may copy and distribute the Program (or a work based on it,
-under Section 2) in object code or executable form under the terms of
-Sections 1 and 2 above provided that you also do one of the following:
+  1. Source Code.
 
-    a) Accompany it with the complete corresponding machine-readable
-    source code, which must be distributed under the terms of Sections
-    1 and 2 above on a medium customarily used for software interchange; or,
+  The "source code" for a work means the preferred form of the work
+for making modifications to it.  "Object code" means any non-source
+form of a work.
 
-    b) Accompany it with a written offer, valid for at least three
-    years, to give any third party, for a charge no more than your
-    cost of physically performing source distribution, a complete
-    machine-readable copy of the corresponding source code, to be
-    distributed under the terms of Sections 1 and 2 above on a medium
-    customarily used for software interchange; or,
+  A "Standard Interface" means an interface that either is an official
+standard defined by a recognized standards body, or, in the case of
+interfaces specified for a particular programming language, one that
+is widely used among developers working in that language.
 
-    c) Accompany it with the information you received as to the offer
-    to distribute corresponding source code.  (This alternative is
-    allowed only for noncommercial distribution and only if you
-    received the program in object code or executable form with such
-    an offer, in accord with Subsection b above.)
+  The "System Libraries" of an executable work include anything, other
+than the work as a whole, that (a) is included in the normal form of
+packaging a Major Component, but which is not part of that Major
+Component, and (b) serves only to enable use of the work with that
+Major Component, or to implement a Standard Interface for which an
+implementation is available to the public in source code form.  A
+"Major Component", in this context, means a major essential component
+(kernel, window system, and so on) of the specific operating system
+(if any) on which the executable work runs, or a compiler used to
+produce the work, or an object code interpreter used to run it.
 
-The source code for a work means the preferred form of the work for
-making modifications to it.  For an executable work, complete source
-code means all the source code for all modules it contains, plus any
-associated interface definition files, plus the scripts used to
-control compilation and installation of the executable.  However, as a
-special exception, the source code distributed need not include
-anything that is normally distributed (in either source or binary
-form) with the major components (compiler, kernel, and so on) of the
-operating system on which the executable runs, unless that component
-itself accompanies the executable.
+  The "Corresponding Source" for a work in object code form means all
+the source code needed to generate, install, and (for an executable
+work) run the object code and to modify the work, including scripts to
+control those activities.  However, it does not include the work's
+System Libraries, or general-purpose tools or generally available free
+programs which are used unmodified in performing those activities but
+which are not part of the work.  For example, Corresponding Source
+includes interface definition files associated with source files for
+the work, and the source code for shared libraries and dynamically
+linked subprograms that the work is specifically designed to require,
+such as by intimate data communication or control flow between those
+subprograms and other parts of the work.
 
-If distribution of executable or object code is made by offering
-access to copy from a designated place, then offering equivalent
-access to copy the source code from the same place counts as
-distribution of the source code, even though third parties are not
-compelled to copy the source along with the object code.
-
-  4. You may not copy, modify, sublicense, or distribute the Program
-except as expressly provided under this License.  Any attempt
-otherwise to copy, modify, sublicense or distribute the Program is
-void, and will automatically terminate your rights under this License.
-However, parties who have received copies, or rights, from you under
-this License will not have their licenses terminated so long as such
-parties remain in full compliance.
+  The Corresponding Source need not include anything that users
+can regenerate automatically from other parts of the Corresponding
+Source.
 
-  5. You are not required to accept this License, since you have not
-signed it.  However, nothing else grants you permission to modify or
-distribute the Program or its derivative works.  These actions are
-prohibited by law if you do not accept this License.  Therefore, by
-modifying or distributing the Program (or any work based on the
-Program), you indicate your acceptance of this License to do so, and
-all its terms and conditions for copying, distributing or modifying
-the Program or works based on it.
+  The Corresponding Source for a work in source code form is that
+same work.
 
-  6. Each time you redistribute the Program (or any work based on the
-Program), the recipient automatically receives a license from the
-original licensor to copy, distribute or modify the Program subject to
-these terms and conditions.  You may not impose any further
-restrictions on the recipients' exercise of the rights granted herein.
-You are not responsible for enforcing compliance by third parties to
+  2. Basic Permissions.
+
+  All rights granted under this License are granted for the term of
+copyright on the Program, and are irrevocable provided the stated
+conditions are met.  This License explicitly affirms your unlimited
+permission to run the unmodified Program.  The output from running a
+covered work is covered by this License only if the output, given its
+content, constitutes a covered work.  This License acknowledges your
+rights of fair use or other equivalent, as provided by copyright law.
+
+  You may make, run and propagate covered works that you do not
+convey, without conditions so long as your license otherwise remains
+in force.  You may convey covered works to others for the sole purpose
+of having them make modifications exclusively for you, or provide you
+with facilities for running those works, provided that you comply with
+the terms of this License in conveying all material for which you do
+not control copyright.  Those thus making or running the covered works
+for you must do so exclusively on your behalf, under your direction
+and control, on terms that prohibit them from making any copies of
+your copyrighted material outside their relationship with you.
+
+  Conveying under any other circumstances is permitted solely under
+the conditions stated below.  Sublicensing is not allowed; section 10
+makes it unnecessary.
+
+  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
+
+  No covered work shall be deemed part of an effective technological
+measure under any applicable law fulfilling obligations under article
+11 of the WIPO copyright treaty adopted on 20 December 1996, or
+similar laws prohibiting or restricting circumvention of such
+measures.
+
+  When you convey a covered work, you waive any legal power to forbid
+circumvention of technological measures to the extent such circumvention
+is effected by exercising rights under this License with respect to
+the covered work, and you disclaim any intention to limit operation or
+modification of the work as a means of enforcing, against the work's
+users, your or third parties' legal rights to forbid circumvention of
+technological measures.
+
+  4. Conveying Verbatim Copies.
+
+  You may convey verbatim copies of the Program's source code as you
+receive it, in any medium, provided that you conspicuously and
+appropriately publish on each copy an appropriate copyright notice;
+keep intact all notices stating that this License and any
+non-permissive terms added in accord with section 7 apply to the code;
+keep intact all notices of the absence of any warranty; and give all
+recipients a copy of this License along with the Program.
+
+  You may charge any price or no price for each copy that you convey,
+and you may offer support or warranty protection for a fee.
+
+  5. Conveying Modified Source Versions.
+
+  You may convey a work based on the Program, or the modifications to
+produce it from the Program, in the form of source code under the
+terms of section 4, provided that you also meet all of these conditions:
+
+    a) The work must carry prominent notices stating that you modified
+    it, and giving a relevant date.
+
+    b) The work must carry prominent notices stating that it is
+    released under this License and any conditions added under section
+    7.  This requirement modifies the requirement in section 4 to
+    "keep intact all notices".
+
+    c) You must license the entire work, as a whole, under this
+    License to anyone who comes into possession of a copy.  This
+    License will therefore apply, along with any applicable section 7
+    additional terms, to the whole of the work, and all its parts,
+    regardless of how they are packaged.  This License gives no
+    permission to license the work in any other way, but it does not
+    invalidate such permission if you have separately received it.
+
+    d) If the work has interactive user interfaces, each must display
+    Appropriate Legal Notices; however, if the Program has interactive
+    interfaces that do not display Appropriate Legal Notices, your
+    work need not make them do so.
+
+  A compilation of a covered work with other separate and independent
+works, which are not by their nature extensions of the covered work,
+and which are not combined with it such as to form a larger program,
+in or on a volume of a storage or distribution medium, is called an
+"aggregate" if the compilation and its resulting copyright are not
+used to limit the access or legal rights of the compilation's users
+beyond what the individual works permit.  Inclusion of a covered work
+in an aggregate does not cause this License to apply to the other
+parts of the aggregate.
+
+  6. Conveying Non-Source Forms.
+
+  You may convey a covered work in object code form under the terms
+of sections 4 and 5, provided that you also convey the
+machine-readable Corresponding Source under the terms of this License,
+in one of these ways:
+
+    a) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by the
+    Corresponding Source fixed on a durable physical medium
+    customarily used for software interchange.
+
+    b) Convey the object code in, or embodied in, a physical product
+    (including a physical distribution medium), accompanied by a
+    written offer, valid for at least three years and valid for as
+    long as you offer spare parts or customer support for that product
+    model, to give anyone who possesses the object code either (1) a
+    copy of the Corresponding Source for all the software in the
+    product that is covered by this License, on a durable physical
+    medium customarily used for software interchange, for a price no
+    more than your reasonable cost of physically performing this
+    conveying of source, or (2) access to copy the
+    Corresponding Source from a network server at no charge.
+
+    c) Convey individual copies of the object code with a copy of the
+    written offer to provide the Corresponding Source.  This
+    alternative is allowed only occasionally and noncommercially, and
+    only if you received the object code with such an offer, in accord
+    with subsection 6b.
+
+    d) Convey the object code by offering access from a designated
+    place (gratis or for a charge), and offer equivalent access to the
+    Corresponding Source in the same way through the same place at no
+    further charge.  You need not require recipients to copy the
+    Corresponding Source along with the object code.  If the place to
+    copy the object code is a network server, the Corresponding Source
+    may be on a different server (operated by you or a third party)
+    that supports equivalent copying facilities, provided you maintain
+    clear directions next to the object code saying where to find the
+    Corresponding Source.  Regardless of what server hosts the
+    Corresponding Source, you remain obligated to ensure that it is
+    available for as long as needed to satisfy these requirements.
+
+    e) Convey the object code using peer-to-peer transmission, provided
+    you inform other peers where the object code and Corresponding
+    Source of the work are being offered to the general public at no
+    charge under subsection 6d.
+
+  A separable portion of the object code, whose source code is excluded
+from the Corresponding Source as a System Library, need not be
+included in conveying the object code work.
+
+  A "User Product" is either (1) a "consumer product", which means any
+tangible personal property which is normally used for personal, family,
+or household purposes, or (2) anything designed or sold for incorporation
+into a dwelling.  In determining whether a product is a consumer product,
+doubtful cases shall be resolved in favor of coverage.  For a particular
+product received by a particular user, "normally used" refers to a
+typical or common use of that class of product, regardless of the status
+of the particular user or of the way in which the particular user
+actually uses, or expects or is expected to use, the product.  A product
+is a consumer product regardless of whether the product has substantial
+commercial, industrial or non-consumer uses, unless such uses represent
+the only significant mode of use of the product.
+
+  "Installation Information" for a User Product means any methods,
+procedures, authorization keys, or other information required to install
+and execute modified versions of a covered work in that User Product from
+a modified version of its Corresponding Source.  The information must
+suffice to ensure that the continued functioning of the modified object
+code is in no case prevented or interfered with solely because
+modification has been made.
+
+  If you convey an object code work under this section in, or with, or
+specifically for use in, a User Product, and the conveying occurs as
+part of a transaction in which the right of possession and use of the
+User Product is transferred to the recipient in perpetuity or for a
+fixed term (regardless of how the transaction is characterized), the
+Corresponding Source conveyed under this section must be accompanied
+by the Installation Information.  But this requirement does not apply
+if neither you nor any third party retains the ability to install
+modified object code on the User Product (for example, the work has
+been installed in ROM).
+
+  The requirement to provide Installation Information does not include a
+requirement to continue to provide support service, warranty, or updates
+for a work that has been modified or installed by the recipient, or for
+the User Product in which it has been modified or installed.  Access to a
+network may be denied when the modification itself materially and
+adversely affects the operation of the network or violates the rules and
+protocols for communication across the network.
+
+  Corresponding Source conveyed, and Installation Information provided,
+in accord with this section must be in a format that is publicly
+documented (and with an implementation available to the public in
+source code form), and must require no special password or key for
+unpacking, reading or copying.
+
+  7. Additional Terms.
+
+  "Additional permissions" are terms that supplement the terms of this
+License by making exceptions from one or more of its conditions.
+Additional permissions that are applicable to the entire Program shall
+be treated as though they were included in this License, to the extent
+that they are valid under applicable law.  If additional permissions
+apply only to part of the Program, that part may be used separately
+under those permissions, but the entire Program remains governed by
+this License without regard to the additional permissions.
+
+  When you convey a copy of a covered work, you may at your option
+remove any additional permissions from that copy, or from any part of
+it.  (Additional permissions may be written to require their own
+removal in certain cases when you modify the work.)  You may place
+additional permissions on material, added by you to a covered work,
+for which you have or can give appropriate copyright permission.
+
+  Notwithstanding any other provision of this License, for material you
+add to a covered work, you may (if authorized by the copyright holders of
+that material) supplement the terms of this License with terms:
+
+    a) Disclaiming warranty or limiting liability differently from the
+    terms of sections 15 and 16 of this License; or
+
+    b) Requiring preservation of specified reasonable legal notices or
+    author attributions in that material or in the Appropriate Legal
+    Notices displayed by works containing it; or
+
+    c) Prohibiting misrepresentation of the origin of that material, or
+    requiring that modified versions of such material be marked in
+    reasonable ways as different from the original version; or
+
+    d) Limiting the use for publicity purposes of names of licensors or
+    authors of the material; or
+
+    e) Declining to grant rights under trademark law for use of some
+    trade names, trademarks, or service marks; or
+
+    f) Requiring indemnification of licensors and authors of that
+    material by anyone who conveys the material (or modified versions of
+    it) with contractual assumptions of liability to the recipient, for
+    any liability that these contractual assumptions directly impose on
+    those licensors and authors.
+
+  All other non-permissive additional terms are considered "further
+restrictions" within the meaning of section 10.  If the Program as you
+received it, or any part of it, contains a notice stating that it is
+governed by this License along with a term that is a further
+restriction, you may remove that term.  If a license document contains
+a further restriction but permits relicensing or conveying under this
+License, you may add to a covered work material governed by the terms
+of that license document, provided that the further restriction does
+not survive such relicensing or conveying.
+
+  If you add terms to a covered work in accord with this section, you
+must place, in the relevant source files, a statement of the
+additional terms that apply to those files, or a notice indicating
+where to find the applicable terms.
+
+  Additional terms, permissive or non-permissive, may be stated in the
+form of a separately written license, or stated as exceptions;
+the above requirements apply either way.
+
+  8. Termination.
+
+  You may not propagate or modify a covered work except as expressly
+provided under this License.  Any attempt otherwise to propagate or
+modify it is void, and will automatically terminate your rights under
+this License (including any patent licenses granted under the third
+paragraph of section 11).
+
+  However, if you cease all violation of this License, then your
+license from a particular copyright holder is reinstated (a)
+provisionally, unless and until the copyright holder explicitly and
+finally terminates your license, and (b) permanently, if the copyright
+holder fails to notify you of the violation by some reasonable means
+prior to 60 days after the cessation.
+
+  Moreover, your license from a particular copyright holder is
+reinstated permanently if the copyright holder notifies you of the
+violation by some reasonable means, this is the first time you have
+received notice of violation of this License (for any work) from that
+copyright holder, and you cure the violation prior to 30 days after
+your receipt of the notice.
+
+  Termination of your rights under this section does not terminate the
+licenses of parties who have received copies or rights from you under
+this License.  If your rights have been terminated and not permanently
+reinstated, you do not qualify to receive new licenses for the same
+material under section 10.
+
+  9. Acceptance Not Required for Having Copies.
+
+  You are not required to accept this License in order to receive or
+run a copy of the Program.  Ancillary propagation of a covered work
+occurring solely as a consequence of using peer-to-peer transmission
+to receive a copy likewise does not require acceptance.  However,
+nothing other than this License grants you permission to propagate or
+modify any covered work.  These actions infringe copyright if you do
+not accept this License.  Therefore, by modifying or propagating a
+covered work, you indicate your acceptance of this License to do so.
+
+  10. Automatic Licensing of Downstream Recipients.
+
+  Each time you convey a covered work, the recipient automatically
+receives a license from the original licensors, to run, modify and
+propagate that work, subject to this License.  You are not responsible
+for enforcing compliance by third parties with this License.
+
+  An "entity transaction" is a transaction transferring control of an
+organization, or substantially all assets of one, or subdividing an
+organization, or merging organizations.  If propagation of a covered
+work results from an entity transaction, each party to that
+transaction who receives a copy of the work also receives whatever
+licenses to the work the party's predecessor in interest had or could
+give under the previous paragraph, plus a right to possession of the
+Corresponding Source of the work from the predecessor in interest, if
+the predecessor has it or can get it with reasonable efforts.
+
+  You may not impose any further restrictions on the exercise of the
+rights granted or affirmed under this License.  For example, you may
+not impose a license fee, royalty, or other charge for exercise of
+rights granted under this License, and you may not initiate litigation
+(including a cross-claim or counterclaim in a lawsuit) alleging that
+any patent claim is infringed by making, using, selling, offering for
+sale, or importing the Program or any portion of it.
+
+  11. Patents.
+
+  A "contributor" is a copyright holder who authorizes use under this
+License of the Program or a work on which the Program is based.  The
+work thus licensed is called the contributor's "contributor version".
+
+  A contributor's "essential patent claims" are all patent claims
+owned or controlled by the contributor, whether already acquired or
+hereafter acquired, that would be infringed by some manner, permitted
+by this License, of making, using, or selling its contributor version,
+but do not include claims that would be infringed only as a
+consequence of further modification of the contributor version.  For
+purposes of this definition, "control" includes the right to grant
+patent sublicenses in a manner consistent with the requirements of
 this License.
 
-  7. If, as a consequence of a court judgment or allegation of patent
-infringement or for any other reason (not limited to patent issues),
-conditions are imposed on you (whether by court order, agreement or
+  Each contributor grants you a non-exclusive, worldwide, royalty-free
+patent license under the contributor's essential patent claims, to
+make, use, sell, offer for sale, import and otherwise run, modify and
+propagate the contents of its contributor version.
+
+  In the following three paragraphs, a "patent license" is any express
+agreement or commitment, however denominated, not to enforce a patent
+(such as an express permission to practice a patent or covenant not to
+sue for patent infringement).  To "grant" such a patent license to a
+party means to make such an agreement or commitment not to enforce a
+patent against the party.
+
+  If you convey a covered work, knowingly relying on a patent license,
+and the Corresponding Source of the work is not available for anyone
+to copy, free of charge and under the terms of this License, through a
+publicly available network server or other readily accessible means,
+then you must either (1) cause the Corresponding Source to be so
+available, or (2) arrange to deprive yourself of the benefit of the
+patent license for this particular work, or (3) arrange, in a manner
+consistent with the requirements of this License, to extend the patent
+license to downstream recipients.  "Knowingly relying" means you have
+actual knowledge that, but for the patent license, your conveying the
+covered work in a country, or your recipient's use of the covered work
+in a country, would infringe one or more identifiable patents in that
+country that you have reason to believe are valid.
+
+  If, pursuant to or in connection with a single transaction or
+arrangement, you convey, or propagate by procuring conveyance of, a
+covered work, and grant a patent license to some of the parties
+receiving the covered work authorizing them to use, propagate, modify
+or convey a specific copy of the covered work, then the patent license
+you grant is automatically extended to all recipients of the covered
+work and works based on it.
+
+  A patent license is "discriminatory" if it does not include within
+the scope of its coverage, prohibits the exercise of, or is
+conditioned on the non-exercise of one or more of the rights that are
+specifically granted under this License.  You may not convey a covered
+work if you are a party to an arrangement with a third party that is
+in the business of distributing software, under which you make payment
+to the third party based on the extent of your activity of conveying
+the work, and under which the third party grants, to any of the
+parties who would receive the covered work from you, a discriminatory
+patent license (a) in connection with copies of the covered work
+conveyed by you (or copies made from those copies), or (b) primarily
+for and in connection with specific products or compilations that
+contain the covered work, unless you entered into that arrangement,
+or that patent license was granted, prior to 28 March 2007.
+
+  Nothing in this License shall be construed as excluding or limiting
+any implied license or other defenses to infringement that may
+otherwise be available to you under applicable patent law.
+
+  12. No Surrender of Others' Freedom.
+
+  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
-excuse you from the conditions of this License.  If you cannot
-distribute so as to satisfy simultaneously your obligations under this
-License and any other pertinent obligations, then as a consequence you
-may not distribute the Program at all.  For example, if a patent
-license would not permit royalty-free redistribution of the Program by
-all those who receive copies directly or indirectly through you, then
-the only way you could satisfy both it and this License would be to
-refrain entirely from distribution of the Program.
+excuse you from the conditions of this License.  If you cannot convey a
+covered work so as to satisfy simultaneously your obligations under this
+License and any other pertinent obligations, then as a consequence you may
+not convey it at all.  For example, if you agree to terms that obligate you
+to collect a royalty for further conveying from those to whom you convey
+the Program, the only way you could satisfy both those terms and this
+License would be to refrain entirely from conveying the Program.
 
-If any portion of this section is held invalid or unenforceable under
-any particular circumstance, the balance of the section is intended to
-apply and the section as a whole is intended to apply in other
-circumstances.
+  13. Use with the GNU Affero General Public License.
 
-It is not the purpose of this section to induce you to infringe any
-patents or other property right claims or to contest validity of any
-such claims; this section has the sole purpose of protecting the
-integrity of the free software distribution system, which is
-implemented by public license practices.  Many people have made
-generous contributions to the wide range of software distributed
-through that system in reliance on consistent application of that
-system; it is up to the author/donor to decide if he or she is willing
-to distribute software through any other system and a licensee cannot
-impose that choice.
+  Notwithstanding any other provision of this License, you have
+permission to link or combine any covered work with a work licensed
+under version 3 of the GNU Affero General Public License into a single
+combined work, and to convey the resulting work.  The terms of this
+License will continue to apply to the part which is the covered work,
+but the special requirements of the GNU Affero General Public License,
+section 13, concerning interaction through a network will apply to the
+combination as such.
 
-This section is intended to make thoroughly clear what is believed to
-be a consequence of the rest of this License.
-
-  8. If the distribution and/or use of the Program is restricted in
-certain countries either by patents or by copyrighted interfaces, the
-original copyright holder who places the Program under this License
-may add an explicit geographical distribution limitation excluding
-those countries, so that distribution is permitted only in or among
-countries not thus excluded.  In such case, this License incorporates
-the limitation as if written in the body of this License.
+  14. Revised Versions of this License.
 
-  9. The Free Software Foundation may publish revised and/or new versions
-of the General Public License from time to time.  Such new versions will
+  The Free Software Foundation may publish revised and/or new versions of
+the GNU General Public License from time to time.  Such new versions will
 be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
 
-Each version is given a distinguishing version number.  If the Program
-specifies a version number of this License which applies to it and "any
-later version", you have the option of following the terms and conditions
-either of that version or of any later version published by the Free
-Software Foundation.  If the Program does not specify a version number of
-this License, you may choose any version ever published by the Free Software
-Foundation.
+  Each version is given a distinguishing version number.  If the
+Program specifies that a certain numbered version of the GNU General
+Public License "or any later version" applies to it, you have the
+option of following the terms and conditions either of that numbered
+version or of any later version published by the Free Software
+Foundation.  If the Program does not specify a version number of the
+GNU General Public License, you may choose any version ever published
+by the Free Software Foundation.
 
-  10. If you wish to incorporate parts of the Program into other free
-programs whose distribution conditions are different, write to the author
-to ask for permission.  For software which is copyrighted by the Free
-Software Foundation, write to the Free Software Foundation; we sometimes
-make exceptions for this.  Our decision will be guided by the two goals
-of preserving the free status of all derivatives of our free software and
-of promoting the sharing and reuse of software generally.
+  If the Program specifies that a proxy can decide which future
+versions of the GNU General Public License can be used, that proxy's
+public statement of acceptance of a version permanently authorizes you
+to choose that version for the Program.
 
-                            NO WARRANTY
+  Later license versions may give you additional or different
+permissions.  However, no additional obligations are imposed on any
+author or copyright holder as a result of your choosing to follow a
+later version.
 
-  11. BECAUSE THE PROGRAM IS LICENSED FREE OF CHARGE, THERE IS NO WARRANTY
-FOR THE PROGRAM, TO THE EXTENT PERMITTED BY APPLICABLE LAW.  EXCEPT WHEN
-OTHERWISE STATED IN WRITING THE COPYRIGHT HOLDERS AND/OR OTHER PARTIES

+# :cd: What is dvdisaster?
+
+**dvdisaster** provides additional [ECC](https://en.m.wikipedia.org/wiki/Error_correction_code) protection for optical media.
+If a medium gets damaged, dvdisaster can recover it as long as the amount of damage is smaller than the amount of ECC data you added to protect it.
+
+It can loosely be compared to [.par2](https://en.m.wikipedia.org/wiki/Parchive) files, but the protection works at the *iso* level instead of working at the file level.
+This way, even if metadata from the optical medium filesystem is damaged, dvdisaster can still work flawlessly.
+
+Please refer to the [PDF manual](documentation/user-manual/manual.pdf) for more information.
+
+# :wrench: Unofficial version
+
+The last upstream version dates back to 2021, and can be found on the [official website](https://dvdisaster.jcea.es).
+
+This version is built on top of the latest upstream version, with the following notable enhancements:
+
+- Added pre-defined sizes for BD-R Triple Layer (100GB), BD-R Quadruple Layer (128GB)
+- Added an option to use more space for ECC on BD-R when using RS03 (`--no-bdr-defect-management`)
+- Re-enabled adaptive reading for RS01 and RS02, and optionally for RS03 on user request (more on that below)
+- Ability to strip an augmented image from its additional ECC-data
+- A new CLI-only version, not depending on gtk (`./configure --with-gui=no && make clean && make -j4`)
+- GUI codebase ported from gtk2 to gtk3 to ensure future-proofness
+- Windows and macOS builds are supported again, those were dropped upstream a few versions back
+- Non-regression tests on each code change, along with prebuilt binaries for Linux64, Windows32/64 and macOS, for both CLI and GUI versions
+- Fixed a bunch of other (minor) quirks, a few (minor) bugs, added a couple other (minor) features
+
+Please refer to the [CHANGELOG](CHANGELOG) for all the details.
+
+This version will never break compatibility with upstream versions,
+the goal is to ensure an optical media protected by upstream dvdisaster will still be able to be repaired
+with this version, decades from now. Regression tests are here to ensure this is the case.
+
+# :twisted_rightwards_arrows: 3 available protection modes ("codecs")
+
+For a more detailed explanation of the algorithms, please refer to the [codecs specification PDF](documentation/codecs.pdf).
+
+:arrow_forward: **RS01** creates error correction files which are stored separately from the image they belong to.
+The artefact is an **ecc** file, which must be stored on another media than the one we're protecting.
+
+:arrow_forward: **RS02** creates error correction data which is added to the medium to protect, we call this *augmenting* the image we're protecting.
+Damaged sectors in the error correction information reduce the data recovering capacity,
+but do not make recovery impossible - a second medium for keeping or protecting the error correction information is not required.
+Intelligent adaptive reading is also available when reading a damaged RS02-protected disc: dvdisaster will only attempt
+to read the minimum amount of required sectors to be able to rebuild the image, using a so-called "divide and conquer"
+seeking mechanism, cutting off up to 90% of the time required to read and recover a damaged media.
+
+:arrow_forward: **RS03** is a further development of RS01 and RS02. It can create both error correction files and
+augmented images, with the following added features:
+
+- It can use multiple CPU cores and is therefore **WAY** faster than RS01/RS02 on modern hardware.
+- RS03 augmented images and error correction files are - contrary to RS01, and to a lesser extent RS02 - robust against
+  damage of the dvdisaster-added recovery data itself
+
+There are, however, a few cons that must be noted for RS03:
+
+- In image mode, the RS03 augmented image file size will be picked up from a predefined list of well-known medium sizes,
+  while the size of augmented images can be freely chosen in RS02. This is the "price to pay" for the added robustness
+  of the correction data.
+- In image mode, intelligent adaptive reading is not available for RS03-protected images. The "divide and conquer"
+  algorithm will still be used, but dvdisaster will not stop as soon as enough sectors have been recovered to rebuild
+  the image: it'll attempt to read them all until you stop it, or until it tried to read all the sectors. You can still
+  stop it manually and attempt a "verify" of the resulting image file, to see if enough data has been read for recovery,
+  otherwise resuming the adaptive reading until this is the case.
+- The changes for parallel computation and higher robustness make RS03 a tiny bit less space efficient, e.g. RS03 error
+  correction data has slighly less (around -3%) error correction capacity than RS02 on images with equal size. This is
+  usually considered a cheap price to pay for the added robustness against corruption.

+
+:one: Here we're talking about the robustness against corruption of the dvdisaster-added ECC parts _themselves_. The higher the ranking, the less it is likely than a few badly located damaged sectors render the whole correction impossible because they affect dvdisaster metadata on-disc. For example, corruption of the first dozens of sectors of an image can make RS02 entirely unusable regardless of the redundancy data originally stored on it.
+
+:two: When algorithm is CPU-bound, i.e. generating or repairing an image stored on a SSD/NVMe drive where the storage i/o speed is not an issue.
+
+:three: Using adaptive reading when supported (RS02), limiting the number of damaged sectors that need to be read to what is strictly necessary for repair. Using linear reading otherwise (RS03 and separate file codecs), assuming a badly damaged media, taking into account the time the drive takes to try to read damaged sectors.
+
+:four: The robustness of RS03 comes at the cost of having to augment images strictly to well-known media sizes, as explained in the previous section above. This usually doesn't make much difference as long as you intend to burn the augmented image to a classic medium (CD-R, DVD-R, BD-R, ...).
+
+# :bulb: Rationale
+
+Even if the peak of the optical media era is well behind us, optical media is still of some value for specific use cases such as off-site backups.
+In any case, we still have media in our hands that we want to be able to repair, should it be damaged, during the next years/decades.
+Repairing is actually pretty much the very reason of dvdisaster existence (as long as parity data has been added, of course).
+The main purpose of this unofficial version is to ensure dvdisaster doesn't get hard to find, use or compile on recent systems.
+To this effect, prebuilt binaries are available for the 3 main categories of operating systems, and on top of that we've also fixed a few
+bugs and added a few tiny features.

+ - Grand finale: add a last new feature which isn't jaw dropping 
+   but very convenient to have (sorry - has nothing to do 
+   with ripping). Since I'm not sure whether there
+   is prior art to this feature, I won't get into
+   details about it until the first release to fence
+   off IP trolls.
+
+Version 1.00: maintenance releases
+   The project is considered finished. By the time we reach
+   1.00, optical media should be as extinct as floppy discs
+   are now. That won't obsolete dvdisaster (quite to the
+   contrary!), but we're probably feature complete in this
+   revision and won't need to introduce new features. 
+   From time to time maintenance releases will be made
+   to adapt for new operating system and toolkit versions.
+
+Unspecified schedule / later releases
+
+ - add pause/resume button
+ - optionally pause after n read errors for drives which
+   need to cool down 
+ - add function for stripping RS02 data from image [done in pl7]
+ - add quiet option for command line mode
+ - display estimated finishing time for encoding/decoding
+ - catch up with many other queued up suggestions
+ - provide a function for searching directories for suitable .ecc files 
+   for the current image
+ - add real UDF parsing to udf.c 
+   (currently only the backward compatibility ISO structures are used)

+Description: Fix GNU Make detection.
+ While the previous code works with earlier versions of bash, it doesn't
+ seem to work with bash 4.4.5. The redirection to /dev/null somehow causes
+ grep to return an error code of 2.
+ .
+ This change allows for more predictable behaviour: grep returns an
+ error code of 0 or 1.

+\begin{abstract}
+This is the {\em blue manual}, describing the data formats of the dvdisaster
+Reed-Solomon codecs which are currently called RS01, RS02 and RS03.
+The codecs create Reed-Solomon parity data to protect data stored on optical media.
+Depending on the codec, parity data can either be stored in a separate file 
+or be integrated with the .iso image on the same medium. 
+See \homepage for additional resources on the dvdisaster pro\-ject,
+e.g. for the {\em orange manual} (manual.pdf) containing information for end users.
+\end{abstract}
+
+\bigskip
+
+{\bf Target audience.} This paper is primarily intended as a working base for the
+dvdisaster developers and, when the final version has been crafted, as an implementation
+guide for third party developers who wish to create and process dvdisaster error correction data.
+It is {\bf neither intended nor suitable} as end-user documentation; for usage information
+please refer to the online documentation at \homepage.
+
+\bigskip
+
+{\bf Prerequisites.} This paper assumes profound knowledge of coding theory and the 
+underlying math. The reader is assumed to have a thorough understanding of Reed-Solomon
+codes, both in theory and from an implementation viewpoint. A basic understanding
+of programming in C is also assumed.

+\section{RS03 CRC block format}
+\label{crc-block}
+
+The crc layer contains 2048 byte blocks containing the data structure
+described below. Except for the CRC32 checksums most of the information
+contained in this data structure is copied from the Ecc Header described
+in appendix \ref{eh}. The crc block format is defined in the include 
+file {\em dvdisaster.h} and has the following C definition:
+
+\begin{tabbing}
+ xxx \= xxxxxxxxxxxxxxxxxxxxxxx \= xxx \kill
+typedef struct \_CrcBlock \\

+\> gint8 methodFlags[4];        \>{\em /* 0-2 for free use by the respective methods; 3 see above */}\\

+\end{tabbing}

+\bigskip
+
+The CrcBlock data structure is used in the CRC layer of RS03 augmented images
+only. RS02 has a similar CRC layer but uses a different concept for retrieving
+layout information from the image. The following table describes the meaning
+and usage of the CrcBlock fields:
+\medskip
+
+\begin{tabular}{|l|p{12cm}|}
+\hline
+Field & Usage \\
+\hline 
+crc & If this data structure is found in the {\em i-th} sector of the CRC layer,
+it contains the CRC32 checksum for data sectors $d_{j,1}, \ldots, d_{j,n}$, with
+$j = (i+1) \bmod\ layer\ size$. See figure \ref{layout-logical} for details.
+Please note that the crc[] array is filled starting from crc[0], and unused field
+are left zero. \\
+\hline
+$cookie$ & Magic byte sequence for recognizing the header.\newline
+Contains the string {\tt *dvdisaster*}. \\
+\hline
+$method$ & 4 characters describing the format; currently only ``RS03''
+may appear here.\\
+\hline
+\end{tabular}
+
+{\footnotesize (continued on next page)}
+\vfill
+\newpage
+
+\begin{tabular}{|l|p{12cm}|}
+\hline
+$methodFlags$ & 4 bytes for further specification of the format.\newline
+Byte 0 contains the following flags:\newline
+Bit 0 - The {\em mediumSum} field is valid.\newline
+Bit 1 - Set to 1 in ecc files.\newline
+Bytes 1-2 are unused in the current methods.\newline
+Byte 3 contains the following flags:\newline
+Bit 0 - ecc data was created by a development release.\newline
+Bit 1 - ecc data was created by a release candidate.\newline
+If these bits are present, the user will be hinted that he is using
+ecc data from a non-stable dvdisaster version. \\
+\hline
+$creatorVersion$ & The dvdisaster version used for creating this ecc data.
+A decimal value 102345 would mean dvdisaster version 10.23.45.\\
+\hline
+$neededVersion$ & The minimum dvdisaster version required for 
+processing this ecc data. Version encoding as above. \\
+\hline
+$fpSector$ & The sector used for calculating $mediumFP$. \\
+\hline
+$mediumFP$ & The md5sum of the sector specified by the {\em fpSector}.
+The sector should be chosen to have a huge probability being unique to the medium;
+currently sector 16 (the ISO filesystem root sector) is used. \\
+\hline
+$mediumSum$ & The md5sum of the original ISO image if the first bit 
+in the {\em methodFlags} field is set. Since md5sum generation can not be
+parallelized, the user may opt not to calculate this checksum if multi core
+encoding is used. \\
+\hline
+$dataSectors$ & For error correction files this is the number of sectors in the
+protected medium. If augmented images are used, this denotes the number of
+sectors in the original ISO image (without the added padding and RS03 sectors). \\
+\hline
+$inLast$ & The number of Bytes contained in the last image sector. This allows for
+encoding of files with arbitrary length, not just ISO images.\\
+\hline
+$dataBytes$ & The number of data layers, including the CRC layer. \\
+\hline
+$eccBytes$ & The number of ecc layers (= number of roots) for the parity. \newline
+$dataBytes + eccBytes = 255$. \\
+\hline
+$sectorsPerLayer$ & The number of sectors per layer. \\
+\hline
+$selfCRC$ & A CRC32 checksum of the ecc header itself. Not used fields are
+set to zero and the selfCRC field is initialized to the 
+value 0x4c5047 (little endian). \\
+\hline
+remaining bytes & The CrcBlock is zero padded to a size of 2048 bytes.\\

+\bigskip
+
+The ecc header is used in all ecc formats (RS01, RS02, RS03) of dvdisaster,
+but not all fields apply to all formats. See the following table for the meaning
+and usage of the fields:
+\bigskip
+
+\begin{tabular}{|l|p{10cm}|c|}
+\hline
+Field & Usage & Format(s) \\
+\hline
+$cookie$ & Magic byte sequence for recognizing the header.\newline
+Contains the string {\tt *dvdisaster*}. & all \\
+\hline
+$method$ & 4 characters describing the format; currently allowed:\newline
+{\tt RS01}, {\tt RS02}, {\tt RS03}. & all \\ 
+\hline
+$methodFlags$ & 4 bytes for further specification of the format. &\\
+ \cline{2-3} 
+ & Byte 0 contains the following flag: &\\
+ & Bit 0 - The {\em mediumSum} field is valid. & RS03 \\
+ & Bit 1 - Set to 1 in ecc files. & RS03 \\
+ \cline{2-3} 
+ & Bytes 1-2 are unused in the current methods. & \\
+ \cline{2-3} 
+ & Byte 3 contains the following flags:\newline
+Bit 0 - ecc data was created by a development release.\newline
+Bit 1 - ecc data was created by a release candidate.\newline
+If these bits are present, the user will be hinted that he is using
+ecc data from a non-stable dvdisaster version. & all \\
+\hline
+\end{tabular}
+
+{\footnotesize (continued on next page)}
+\vfill
+\newpage
+
+\begin{tabular}{|l|p{10cm}|c|}
+\hline
+$mediumFP$ & The md5sum of the sector specified by the {\em fpSector}.
+The sector should be chosen to have a huge probability being unique to the medium;
+currently sector 16 (the ISO filesystem root sector) is used. & all \\
+\hline
+$mediumSum$ & The md5sum of the ISO image. For RS01 this is the md5sum of the
+whole image; for RS02 it is calculated for the original ISO image (without
+the added RS02 sectors). RS03 uses this value only when bit 1 in
+{\em methodFlags} is set. & all \\ 
+\hline
+$eccSum$ & On RS01 this is the md5sum of the ecc file excluding the first 4096
+bytes. For RS02 this is the md5sum calculated over the md5sums of the $nroots$
+ecc layers. RS03 does not use this value. & RS01, RS02 \\
+\hline
+$sectors$ & For error correction files this is the number of sectors in the
+protected medium. If augmented images are used, this denotes the number of
+sectors in the original ISO image (without the added RS02/RS03 sectors). & all \\
+\hline
+$dataBytes$ & The number of data layers, including the CRC layer. & all \\
+\hline
+$eccBytes$ & The number of ecc layers (= number of roots) for the parity.
+$dataBytes + eccBytes = 255$. & all\\
+\hline
+$creatorVersion$ & The dvdisaster version used for creating this ecc data.
+A decimal value 102345 would mean dvdisaster version 10.23.45. & all \\
+\hline
+$neededVersion$ & The minimum dvdisaster version required for 
+processing this ecc data. Version encoding as above. & all \\
+\hline
+$fpSector$ & The sector used for calculating $mediumFP$. & all \\
+\hline
+$selfCRC$ & A CRC32 checksum of the ecc header itself. Not used 
+header fields are set to zero and the selfCRC field is initialized to the 
+value 0x4c5047 (little endian). & \\
+\hline
+$crcSum$ & md5sum of the CRC layer in RS02 encoded images. & RS02 \\
+\hline
+$inLast$ & The number of Bytes contained in the last image sector. This allows for
+encoding of files with arbitrary length, not just ISO images. 
+dvdisaster versions prior to V0.66 do not use this field and always assume it
+to be 2048 which is the default for iso images. & all \\
+\hline
+$sectorsPerLayer$ & The number of sectors per layer. & RS03 \\
+\hline
+$sectorsAddedByEcc$ & The total number of sectors (Headers, CRC, ECC) added. & RS02 \\
+\hline
+$padding$ & The ecc header is zero padded to a length of 4096 bytes. Future codes
+may allocate additional space for the zero padding. See the note below for
+usage of the upper 2048 bytes on RS02/RS03. & all \\
+\hline
+Byte 2048-4096 & A copy of the first CRC layer sector. & RS02 \\

+\section{RS(255,k) encoding parameters and examples}
+\label{rs}
+
+dvdisaster uses a standard, non-shortened Reed-Solomon code
+with the following commonly used parameters: \smallskip
+
+The Galois field tables are generated by the field
+generator polynomial 0x187 ($1 + X + X^2 + X^7 + X^8$).
+The Reed-Solomon code generator polynomial is created using element 
+0x70 as first consecutive root and the primitive element 0x0b. \medskip
+
+As a starting point for testing your own implementation, some 
+values and tables are shown below. The logarithm
+and anti-logarithm tables in the Galois field are shown in tables
+\ref{log-table} and \ref{anti-log-table}. Please note that there is no need for hard-coding
+these tables as their contents can be enumerated by using
+the field generator polynomial. \medskip
+
+When encoding for 32 roots, the RS code generator polynomial will be:
+
+{\small 01 5b 7f 56 10 1e 0d eb 61 a5 08 2a 36 56 ab 20 71 20 ab 56 36 2a 08 a5 61 eb 0d 1e 10 56 7f 5b 01}
+
+or in index form:
+
+{\small 00 f9 3b 42 04 2b 7e fb 61 1e 03 d5 32 42 aa 05 18 05 aa 42 32 d5 03 1e 61 fb 7e 2b 04 42 3b f9 00} \medskip
+
+Using the above generator polynomial for encoding the data byte
+sequence $\{0,1,\ldots,222\}$ produces the following parity bytes:
+
+{\small 2f bd 4f b4 74 84 94 b9 ac d5 54 62 72 12 ee b3 eb ed 41 19 1d e1 d3 63 20 ea 49 29 0b 25 ab cf}

+\section{The RS01 codec}
+\label{rs01}
+This section describes the dvdisaster RS01 Reed-Solomon codec. 
+It was conceived during the summer of 2004 for creating 
+error correction files in the first dvdisaster versions.
+At this time, CD media was still predominant. 
+Typical machines were based on Pentium 4 (tm) processors.
+Measured by todays standards physical RAM and hard disk
+space were scarce, and especially hard disk random I/O
+was extremely slow. 
+
+\smallskip
+
+In order to work efficiently with the available technology,
+RS01 was designed to be as space efficient as possible 
+and to minimize hard disk random access. 
+Optimizing the data layout for random access efficiency
+lead to a parity byte distribution which left the error correction
+file vulnerable to being damaged. RS01 was 
+occasionally being critcized for not being able to recover 
+from damaged error corrction files, but these points
+were not really fair. RS01 error correction
+files were never designed for being stored on fragile
+media. They are supposed to
+be either stored on hard disk, or to be stored on optical
+media which itself is protected by dvdisaster error
+correction which has the following consequences:
+ Unlike optical media, hard disks do not degrade
+gradually. Hard disks are usually either 100\% readable or 
+completely dead, so we can assume that error correction
+files on hard disk are either completely readable or fully lost.
+
+Storing error correction files on optical media is a different
+story. While an error correction file could protect itself to some
+degree against lost sectors (as RS03 ecc files do), it is still
+prone to the shortcomings of a file level error correction. 
+The biggest disadvantage of file level error correction is
+that there is no protection of file system meta data.
+If meta data like a directory node becomes damaged, all files
+in the directory are lost regardless of the redundancy contained
+within the files. Therefore any medium containing error 
+correction files must be protected with an image level
+error correction layer (by using RS01,RS02 or RS03 on the medium), 
+since only image level error correction avoids meta 
+data sectors to become a single point of failure. See the
+discussion at \url{https://web.archive.org/web/20180428070843/http://dvdisaster.net/en/qa32.html} for
+more information on the advantages of image level data protection
+over file level approaches.
+
+\smallskip
+
+Nevertheless, the time has come to phase out the RS01 codec.
+Consider creating an error correction file with 32 roots 
+for a 650MiB sized image using both  codecs\footnote{The benchmark was
+done using the GNU/Linux version 
+of dvdisaster 0.79.4 on a AMD Athlon(tm) II X4 615e 
+processor. RS03 used all 4 cores of the machine.
+Both image and ecc files were stored in {\tt /dev/shm}
+to rule out I/O effects.}:
+
+\begin{center}
+\begin{tabular}{|l|r|r|}
+\hline
+codec & ecc file size & encoding time \\
+\hline
+RS01 & 94.58MiB & 46.2s \\
+RS03 & 96.68MiB &  2.4s \\
+\hline
+\end{tabular}
+\end{center}
+
+RS03 is about 2.2\% less storage efficient than RS01 since
+its data layout has been rearranged for better parallelization.
+But this is made up by a 19-fold speed improvement as
+RS03 can use multiple cores and SSE2 extensions
+(of course the speed improvement varies depending on the
+hardware used).
+Since all other properties of RS03 do at least match those
+of RS01, it's fair to begin phasing out RS01 in dvdisaster.
+
+%\smallskip
+
+dvdisaster V0.80 will be the first and only version 
+featuring all three codecs. In version 0.82, users
+will be presented a note the RS01 became deprecated.
+In subsequent releases support for encoding RS01 will
+be removed. Of course, capabilities to use and decode
+RS01 will remain in dvdisaster for umlimited time.
+Existing RS01 error correction files should remain in use
+and there is be no need to replace them with RS03 ones.
+
+\subsection{Physical layout}
+
+\begin{figure}
+ \begin{center}
+ \includegraphics[width=67mm]{spiral-rs01.eps}
+ \caption{Interpretation of physical layout in the .iso image}
+ \label{layout-phy-one}
+ \end{center}
+\end{figure}
+
+RS01 is meant to protect data which has already been written to an optical
+medium, so the parity data can not be appended to the medium and must instead 
+be kept in a separate error correction file. Like all dvdisaster
+codecs, RS01 is based on a RS(255,k) Reed-Solomon code with  each
+ecc block being comprised of $n$ data bytes and $k$ parity bytes, and
+$n+k=255$.
+
+The $n$ data bytes are taken from an iso image generated from the medium.
+Reading data directly from the optical drive during encoding would slow down the
+process tremendously due to massive random access over the medium, and 
+quickly wear out the drive mechanics. However producing the .iso image 
+takes one fast linear read, accesses the drive in a way it is designed to be used,
+and puts the data on hard disk which can sustain the needed random access I/O.
+
+Reed-Solomon codes
+work best when errors are evenly distributed over all ecc blocks.
+Therefore the $n$ data bytes used for creating an ecc block must be picked from
+locations which are evenly distributed over the medium with a maximum
+distance between each data byte pair. To obtain a suitable data distribution,
+it is taken  into account that optical media are recorded as a single long 
+spiral\footnote{Multiple layered
+media contain one spiral for each physical layer, but are otherwise conceptually
+identical.} of sectors each containing 2048 bytes.
+The first sector lies at the innermost position of the spiral and is indexed with 0;
+numbering continues onward to the outside of the spiral. The .iso image
+contains a 1:1 mapping of this storage scheme, with the first 2048 bytes
+holding the contents of sector 0, the next 2048 bytes resembling sector 1, and so on.
+
+When encoding with $n$ data bytes per ecc block, the iso image is divided into
+$n$ layers which physically map to the medium as shown in fig.\ref{layout-phy-one}. 
+This distributes the ecc block reasonably good over the medium surface.
+However since the image size does not need
+to be a multiple of the layer size, the $n$-th layer may be physically shorter
+as the layer size. For encoding purposes, the non-existant sectors in layer
+$n$ are treated as sectors being filled with 2048 zero bytes. 
+
+\subsection{Logical ecc file layout}
+
+\begin{figure}
+ \begin{center}
+ \includegraphics[width=\textwidth]{rs01-layout.eps}
+ \caption{Logical RS01 layout}
+ \label{layout-logical-one}
+ \end{center}
+\end{figure}
+
+The ecc file layout, and therefore the relationship between the iso image
+contents and the ecc file, is shown in 
+figure \ref{layout-logical-one}. The first 4096 bytes of the ecc file
+contain the ecc header whose format is described in appendix \ref{eh}.
+For RS01, only the data fields marked with ``all'' or ``RS01'' are
+relevant; all other fields should be set to zero.
+
+Next to the ecc header comes the CRC section of the ecc file. If the
+iso image contains $s$ sectors, the next $4*s$ bytes in the ecc file
+contain the CRC32 sums of the sectors from the iso image: Let $b_1,\dots,b_{2048}$ denote 
+the bytes of the first data sector; $b_{2049},\dots,b_{4096}$ those of the
+second data sector and so on. Then $c_1 = CRC32(b_1,\dots,b_{2048})$,
+$c_2 = CRC32(b_{2049},\dots,b_{4096})$ etc. Note that in contrast to
+RS02 and RS03, bytes from the CRC section are not included into the ecc block
+calculation and are therefore not protected by ecc.
+
+\smallskip
+
+The remainder of the ecc file contains the parity bytes of the
+ecc blocks. For an ecc file built with $k$ roots, 
+the iso image is logically divided into 
+$n = 255-k$ layers as shown in figure \ref{layout-logical-one}.
+The $d_{i,j}$ denote the $i-th$ byte in the $j-th$ layer.
+In order to create the first ecc block, bytes $d_{1,1}$ to  $d_{1,n}$ are taken from the
+$n$ layers. Then the RS(255,k) code is calculated (see appendix \ref{rs} for its parameters)
+and the 
+resulting $k$ parity bytes $e_{1,1}$ up to $e_{k,1}$ are stored
+in the ecc file. The resulting ecc block is marked grey in the
+figure. The next ecc blocks are calculated and stored accordingly.
+In total, the ecc section contains $k*ls$ bytes of parity information,
+with the $k$ parity bytes of each ecc block being stored consecutively.
+
+\subsection{Calculating the layout for encoding}
+
+The RS01 layout is fully determined by the number of roots for the error correction code
+and the iso image size in sectors (from now on, ``size'' always means ``number of
+2048K sectors). The number of roots can be freely chosen by the user from the
+range of $[8...100]$. The iso image size is directly measured
+from the iso image file.
+
+\smallskip
+
+The number of data layers is simply calculated from the number of roots, $k$:
+
+\[ data\ layers = 255 - k\]
+
+The size of each layer is:
+
+\[ layer\ size = \left\lceil\frac{medium\ size}{data\ layers}\right\rceil\]
+
+At the end of the last layer, $data\ layers * layer\ size - medium\ size$
+zero filled padding sectors are used in the encoding process.
+
+\subsection{Getting the layout when recovering defective media}
+
+The required parameters are taken from the ecc header stored in
+the error correction file (see appendix \ref{eh}). Especially,
+the number of roots are taken from the {\em eccBytes} field and
+the medium size is recorded in the {\em sectors} field.
+
+\subsection{md5 checksums}
+
+RS01 provides two md5 checksums for integrity checking.
+The md5 sum of the iso image is calculated and stored in the
+{\em mediumSum} field of the ecc header. 
+Another md5 sum is calculated over the ecc file, excluding the
+first 4096 bytes, and stored in the {\em eccSum} field of
+the ecc header. It can be used to verify the integrity of the
+ecc file itself. The ecc header is protected by its own CRC
+checksum which is stored in the {\em selfCRC} field.
+
+\smallskip
+
+The md5 checksum generation is the major obstacle for parallelizing
+the encoder. In RS03, md5sum generation has been made optional since
+the RS03 layout allows suffcient consistency checks 
+by doing a quick error syndrome check using the Reed-Solomon code.
+
+\subsection{Special cases}
+
+Error correction files can be created for any type of input files, not just iso files,
+as long as the input files are ``reasonably'' long\footnote{Input files should contain
+at least 2048*(255-k) bytes, so that there is at least one sector for each data
+layer.}. Since input files are processed in units of 2048 kByte sectors, 
+files whose byte size is not an integer multiple of 2048 are virtually padded 
+with zeroes. In that case, the {\em inLast} field of the ecc header
+contains the real byte size of the last file ``sector'' so that recovering the
+last file sector does not write out the padding bytes. A size of zero in the
+{\em inLast} field means that the last sector contains 2048 bytes.

+\section{The RS02 codec}
+
+This section describes the dvdisaster RS02 Reed-Solomon codec.
+It was developed during the winter of 2005/2006 in order to facilitate
+augmenting iso images directly with error correction data.
+
+RS02 is based on the Reed-Solomon encoders and decoders 
+introduced with RS01, but focuses exclusively on augmenting
+iso images. The allocation of data sectors within an ecc block 
+follows a similar scheme as in RS01. However the layout of the
+parity bytes is vastly different between RS01 and RS02, as the codec must
+cope with any parity sector being damaged or unreadable. 
+Consequently a RS02 image can lose as many sectors as 
+allowed by the redundancy of
+the error correction data, and the lost sectors can be any
+combination of data and parity sectors, as it is expected from
+a Reed-Solomon scheme.
+
+\smallskip
+
+Unlike RS01, which will be completely superseded by RS03 soon,
+the case of RS02 vs. RS03 still remains open, as both codecs
+have their individual strengths. RS02 is slightly more space
+efficient than RS03, so on CD media RS02 might provide
+slightly more redundancy (typically one additional root) than RS03. 
+This effect will be less
+pronounced on larger media like DVD and BD. 
+RS02 images can be augmented to an arbitrary size which may
+be smaller than the maximum medium size, while RS03 requires
+augmenting the image to the full medium size.
+This might favour RS02 for working on images which are only
+30\% or less of the medium size, as they can be encoded with
+less than the maximum of 170 roots 
+(the maximum redundancy requires lots of time to compute, producing
+a three-fold redundancy which may not be needed in all cases). 
+On the other hand RS03 will counter
+the performance argument since it can encode at least 
+20 times faster than RS02 on multi-core architectures, 
+because RS02 encoding can not be parallelized. 
+See the end of section \ref{rs01}  for a speed comparison of RS01 vs. RS03; 
+RS01 and RS02 are very similar performance-wise.
+Finally, the data layout of RS03 does not depend on interspersed
+ecc headers which gives it a better robustness over RS02;
+see subsection \ref{layout-logical-two} for details.
+
+\subsection{Physical layout}
+

+ \end{center}
+\end{figure}
+
+RS02 must be applied to the .iso image before it is written to
+the medium. Additional sectors are appended to the .iso image 
+containing the parity data. The data structures of the .iso image
+are not changed to reflect the new image size, so the original
+part of the augmented .iso image remains untouched. The parity
+sectors can be removed from the augmented image by simply 
+truncating the .iso image to its original sector size; the resulting
+image file will have the same contents as prior to the augmentation.
+As a side effect, the parity data is invisible to applications reading
+the medium at the filesystem level, including most hardware media
+players. If you find a player which gets confused by media containing
+RS02 (or RS03) parity, please consider telling the dvdisaster project about it. As of this writing,
+not a single device has been reported to run into problems with
+the RS02 data scheme. The RS02 augmented image might conflict with
+optical media writing software, though. If the writing software
+decides the image length by looking at the iso filesystem structures,
+the parity data portion of the image might not be written to the medium.
+Most current writing programs do however measure the .iso image by examining
+its file size, and will transfer the parity data correctly. To be sure you
+should follow the steps described under ``Testing image compatibility''

+before using each version of your optical media authoring software.
+
+Like the other dvdisaster codecs, RS02 is based on a  RS(255,k) Reed-Solomon code
+with each ecc block being comprised of $n$ data bytes and $k$ parity bytes, and
+$n+k=255$. The $n$ data bytes comprise the .iso image which will be
+written to the medium, and the additional ecc header and CRC checksums added
+by dvdisaster. Reed-Solomon encoding works best when errors are
+distributed evenly over all ecc blocks. Therefore we must strive to distribute
+the ecc blocks evenly over the medium surface. To facilitate such mapping,
+dvdisaster logically divides the medium into 255 logical units which are called
+``layers'' for historical reasons. 
+Figure \ref{layout-phy-two} shows how the medium is divided into $n$ data layers
+and $k$ ecc layers, with $n + k = 255$. Ecc blocks are
+created by taking on byte from each layer as shown in fig. \ref{layout-logical-two}
+on the following page. This distributes the ecc block reasonably good over
+the medium surface. 
+All layers have the same length in bytes, with the possible exception of
+data layer $n$. As the .iso image size plus the size of one ecc header and the CRC data
+is usually not a multiple of the layer size, the $n$-th data layer may be shorter
+than the layer size and considered to be filled up with a virtual zero padding. 
+The zero padding is not written out to the augmented image (note that data layer $n$
+is intentionally drawn shorter in fig. \ref{layout-phy-two}), but it is used in the
+calculation of the respective parity bytes.
+
+\newpage
+
+\subsection{Logical layout}
+\label{sec-layout-logical-two}
+
+\begin{figure}
+ \begin{center}
+ \includegraphics[width=\textwidth]{rs02-layout.eps}
+ \caption{Logical RS02 layout}
+ \label{layout-logical-two}
+ \end{center}
+\end{figure}
+
+The data layout in the augmented image is shown in figure \ref{layout-logical-two}.
+Note that in this figure the data is byte-indexed; e.g. $d_{1,1}$ denotes the
+first data byte in the augmented image. Each layer has a length of
+$ls$ bytes, with the exception of data layer $n$ which may be shortened (see subsection \ref{calc-two} for an exact calculation of its size). 
+Some ecc layers my be interleaved with redundant copies of the ecc header. 
+The ecc header size is not included in the respective ecc layer size.
+
+\paragraph{Data layers.} A data layer index $d_{i,j}$ refers to the $i$-th byte in the $j$-th data layer.
+The $n$ data layers are mapped in a linear fashion to the original iso image.
+$d_{1,1}$ maps to the first .iso image byte, and $d_{ns,n}$ maps to the last .iso image
+byte ($ns$ is the number of remaining iso image bytes in the $n$-th data layer). 
+
+The last data layer is special because it does not only contain the rest of the iso image,
+but also the ecc header and the CRC checksums. These extensions 
+are logically treated as a part of the iso image; their contents are used in the
+ecc data calculation and are therefore protected by the ecc data.
+The ecc header follows immediately after byte $d_{ns,n}$ and is 4096 bytes long.
+Its format is described in appendix \ref{eh}. For RS02, only the data fields
+marked with ``all'' or ``RS02'' are relevant; all other fields should be set to zero.
+
+Data layer $n$ does also contain the CRC32 checksums of each data sector
+up to the ecc header. If the .iso image contains $s$ sectors,
+then the CRC field contains $4s$ bytes, rounded up
+to the nearest multiple of 2048. 
+CRC32 checksums are calculated over a whole CD sector comprising 2048 bytes.
+Let $c_{y,j}$ be the 4-byte checksum of the $y$-th sector in the $j$-th layer
+and $lss$ be the number of sectors in each layer.
+Then $c_{y,j}$ = CRC32($d_{2048*y,j}$, $d_{2048*y+1,j}$, \dots, $d_{2048*y+2047,j}$).  
+ 
+$y_1$ is usually not the first sector in the layer, but a later sector.
+In general, $y_i$ = $(i+offset)$ mod $lss$. The offset is introduced to restore
+the CRC32 sums of ecc block $i+1$ during the correction of ecc block $i$.
+This helps if the data portion of the image is corrupted with wrong byte values and
+the sectors containing the CRC32 sums have been lost. 
+The error correction will start at the ecc block $i$ which is determined
+by the offset, and whose CRC32 checksums are stored in the ecc header (at least one
+ecc header will be recovered before any error correction can begin). Correcting
+ecc block $i$ will recover the CRC32 checksums for ecc block $i+1$ in the image
+(and possibly some more in advance, as less than 2048 bytes are required for
+one set of checksums). This makes it possible to detect corrupted bytes by the
+checksums and flag them as erasures which effectively doubles the error correction
+capabilities of the Reed-Solomon code.
+
+\paragraph{Ecc layers.} For an image augmented with $k$ roots, the parity bytes
+will be spread over $k$ ecc layers. In order to calculate the first ecc block,
+bytes $d_{1,1}$ to $d_{1,n}$ are taken from the $n$ data layers. The RS(255,k) code
+is calculated (see appendix \ref{rs} for its parameters) and the resulting $k$
+parity bytes $e_{1,1}$ to $e_{1,k}$ are stored in the $k$ ecc layers. 
+The next ecc blocks are calculated and stored accordingly; ecc block $i$ 
+is marked grey in the figure.
+Care must be taken to honour the non-linear mapping of
+ecc layer bytes as the ecc area is interleaved with 20-40 copies of the ecc header.
+The ecc header copies are placed at sector addresses whose numbers 
+are large powers of two. This makes it possible to heuristically search for them
+during the decoding boot-strap process 
+when no other information (image size, layer size, etc.) is yet available.
+See section \ref{search-two} on the search heuristics and section \ref{addressing-two}
+on calculating ecc bytes positions from the non-linear mapping. 
+
+\subsection{Calculating the image layout for encoding}
+
+The image layout can be either computed automatically to fill up
+the medium as much as possible, or by user selected criteria such
+as a maximum image size or a specified redundancy.
+
+\subsubsection{Automatic layout calculation}
+\label{calc-two}
+
+The only available inputs to automatic layout detection are
+the .iso image size and a table of maximum media sizes (see
+tab. \ref{layout-size-table} in the RS03 section for the
+respective values). From the media size table the smallest
+possible medium  is chosen which can contain the .iso image.
+In some border cases, with e.g. the .iso image being only
+100 sectors smaller than the medium capacity, the automatic
+layout calculation will fail later due to insufficient space
+on the medium. In such cases, the user must decide between
+choosing the next larger medium size or splitting the image
+contents onto two media by himself (splitting a 700MiB CD image 
+onto two CDs may be better than writing it to a DVD).
+
+\smallskip
+
+From now on, all calculations are given in numbers of 2048K 
+sectors or sectors addresses
+unless noted otherwise. The number of sectors required for the
+CRC checksums can be directly computed from the .iso image size:
+
+\[
+crc\; sectors = \left\lceil\frac{4 * iso\; image\; sectors}{2048}\right\rceil
+\]
+
+The total accumulated size of all data layers is the sum of the
+.iso image size, the number of crc sectors and the two sectors required
+for the ecc header. Since these sectors are protected by the parity,
+they are called {\em protected sectors}:
+
+\[protected\; sectors = iso\; image\; size + 2 + crc\; sectors\]
+ 
+These calculations also produce two important sector addresses within
+the augmented image:
+
+\begin{itemize}
+\item The sector with address {\em iso image size} marks the location
+of the ecc header; and
+\item The sector at address $iso\; image\; size + 2$ marks the beginning
+of the CRC checksum data.
+\end{itemize}
+
+The next step is to partition the {\em protected sectors} and the remaining
+medium space into an optimal layer size. It is carried out iteratively.
+
+\smallskip
+
+For an approximate start, we determine the free space on the medium:
+
+\[free\; space = medium\; capacity - protected\; sectors\]
+
+and estimate a preliminary value for the number of roots and data layers:
+
+\[k\; roots = min\left(170, \quad\left\lfloor\frac{255 * free\; space}{medium\; capacity}\right\rfloor\right)\]
+
+\[n\; data = 255 - k\; roots\]
+
+The maximum number of roots is capped at 170 which is approximately a three-fold
+redundancy. Larger values would get too computationally expensive.
+
+\smallskip
+
+The preliminary layer size is then:
+
+\[preliminary\; layer\; size = \left\lceil\frac{protected\; sectors}{n\; data}\right\rceil\]
+
+and the expected size of the parity layers is:
+
+\[preliminary\; ecc\; size = k\; roots * preliminary\; layer\; size\]
+
+\smallskip
+
+% TODO: implement in codec
+\begin{comment}
+
+From these values we iteratively compute a $2^p$ which has about 20-40 multiples
+in the {\em preliminary ecc size} address space. This value will be used
+for interleaving the ecc header copies with the ecc layers:
+
+\smallskip
+
+{\tt
+p := 5
+
+while($\frac{preliminary\;ecc\;size}{2^p} > 40$)
+
+\quad p := p + 1}  
+\end{comment}
+
+From these values we compute a $2^p$ which has about 20-40 multiples
+in the {\em preliminary ecc size} address space. This value will be used
+for interleaving the ecc header copies with the ecc layers:
+
+\[ p = \left\lceil log_2\; \frac{preliminary\;ecc\;size}{40} \right\rceil \]
+
+%\[ p = \left\lceil \frac{log\; \frac{preliminary\;ecc\;size}{40}}{log\; 2} \right\rceil \]
+
+
+\smallskip
+
+Now the chosen values might be actually too big since we haven't taken
+the ecc header copies into account. 
+So the final task is to add up the number pf parity sectors and ecc header
+copies. If these fit into the free medium space, we are done; otherwise
+the calculations are done again with one root less.
+

+
+while($n\; roots > 7$)
+
+\smallskip
+
+\quad $layer\; size := \left\lceil\frac{protected\; sectors}{n\; data}\right\rceil$
+

+
+\smallskip
+
+\quad Otherwise, set $n\; roots := n\; roots - 1$ and $n\; data := 255 - n\; roots$
+and do another iteration. 
+
+\medskip
+
+The iteration will either terminate with a valid layout or fail when
+$n\; roots$ drops below the minimum redundancy of 8 roots. 
+
+\subsubsection{Layout calculation by user selected criteria}
+
+The user has several means of specifying a certain redundancy:
+
+\paragraph{Specifying the maximum number of sectors for the augmented image.}
+
+This case is simply handled by setting {\em medium capacity} to the user
+selected sector size rather than using the maximum medium size from the
+built-in table. Afterwards, calculations continue as described in
+section \ref{calc-two}.
+
+\paragraph{Specifying the number of roots to use.}
+
+In this case we can skip the calculations for {\em free space} and
+{\em k roots} as described in section \ref{calc-two}, and instead
+set {\em k roots} directly to the user selected value. Then the
+layout calculation proceeds as usual. 
+
+\paragraph{Specifying the percentage of redundancy to use.}
+
+For a given number of {\em k roots}, the resulting redundancy in percent is:
+
+\[\frac{k\; roots \cdot 100}{255 - k\; roots}\]
+
+Pick a suitable value for {\em k roots} so that the user selected value
+is met or slightly exceeded. Proceed with the given number of roots
+as described in the previous paragraph.
+
+\subsubsection{Layout calculation from ecc header information}
+\label{recalc-layout-header-two}
+
+In a given ecc header struct {\em eh}, the number of sectors in the .iso
+image is recorded as \mbox{\em eh-$>$sectors} 
+and the number of roots is contained in \mbox{\em eh-$>$eccBytes}.
+Calculation of the layout is done as shown in section \ref{calc-two}, 
+with the exception of omitting the calculation for {\em free space} and
+setting {\em k roots} directly to  \mbox{\em eh-$>$eccBytes}.
+
+\subsection{Automatic layout calculation example}
+\label{example-two}
+
+Let's assume we are going to encode an .iso image of 295.000 sectors.
+This is well below the CD medium capacity of 359.424 sectors, so we
+start with:
+
+\smallskip
+
+$medium\; capacity = 359.424\; sectors$
+
+$iso\; image\; size = 295.000\; sectors$
+
+\medskip
+
+The number of CRC sectors will be:
+
+\smallskip
+
+$crc\; sectors = \left\lfloor\frac{4 * 295.000}{2.048}\right\rfloor = 577\; sectors$
+
+\medskip
+
+The total size of all data layers is:
+
+$protected\; sectors = 295.000 + 2 + 577 = 295.579\; sectors$
+
+\bigskip
+
+The next step is creating some preliminary starting values:
+
+\smallskip
+
+$free\; space = 359.424 - 295.579 = 63.845\; sectors$
+
+\smallskip
+
+$k\; roots = min\left(170, \left\lfloor\frac{255* 63.845}{359.424}\right\rfloor\right) = min(170, 45) = 45\; roots\; (or\; layers)$
+
+\smallskip
+
+$n\; data = 255 - 45 = 210\; layers$
+
+\bigskip
+
+Now some more preliminary values can be computed:
+
+\smallskip
+
+$preliminary\; layer\; size = \left\lceil\frac{295.579}{210}\right\rceil = 1.408\; sectors$
+
+\smallskip
+
+$preliminary\; ecc\; size = 45 * 1.408 = 63.360\; sectors$
+
+\bigskip
+
+Finally, we compute $p = 11$ since $\frac{63360}{2^{11}} = 30,9$.
+
+\bigskip
+
+Now the chosen values must be verified to produce a layout which is
+still smaller than the image size. We compute (the first two values are already known):
+
+\medskip
+
+$layer\; size = \left\lceil\frac{295.579}{210}\right\rceil = 1.408\; sectors$
+
+\smallskip
+
+$ecc\; size = 45 * 1.408 = 63.360\; sectors$
+
+\smallskip
+
+$first\; ecc\; header\; repeat\; addr = \left\lceil\frac{295.579}{2048}\right\rceil * 2048 = 296.960$
+
+\smallskip 
+
+$space\; for\; interleaved\; sectors = 295.579 + 63.360 - 296.960 = 61.979\; sectors$
+
+\smallskip
+
+$number\; of\; ecc\; copies = \left\lfloor\frac{61.979}{2048-2}\right\rfloor + 1 = 31\; header\; repeats$
+
+\smallskip
+
+$total\; added\; sectors = 2 + 577 + 63.360 + 2 * 31 = 64.001\; sectors$
+
+\medskip
+
+This layout will generate an augmented image containing
+$295.000 + 64.001 = 359.001$ sectors which is 
+less than the medium capacity of 359.424 sectors
+and therefore accepted.
+
+\subsection{Re-calculating the layout from defective media}
+\label{search-two}
+
+In order to recover a defective medium, at least one ecc header must
+remain readable and be located by the following heuristic. This
+is a major difference to RS03, which has more and different means
+for bootstrapping the recovery (see section \ref{recover} for details).
+Once one ecc header has been recovered, the ecc data layout can be
+calculated as described in section \ref{recalc-layout-header-two}.
+From this point, the error correction is done using the parameters
+and data described in section \ref{encoding-two}.
+
+\smallskip
+
+If the medium is not damaged or only slightly damaged, the following
+short cut might work: The size of the .iso image can be determined
+from the iso file system header. Then the ecc header immediately
+following the .iso image part of the augmented image is either
+located at sector number $iso\;image\;size$ or $iso\;image\;size + 150$.
+The latter case arises because some popular CD authoring software
+appends 150 padding sectors to any .iso image it creates. 
+
+\smallskip
+
+If the short cut does not work due to the required sectors being damaged,
+the following strategy is employed. The size of the augmented image
+can always be determined; it can either be queried from the drive or
+it is the file size of a file-based image. Then apply the following
+algorithm:
+
+\bigskip
+
+$p = \left\lfloor log_2(image\; size)\right\rfloor$
+
+while $p > 32$
+
+\quad $pos = \left\lfloor\frac{image\; size}{2^p}\right\rfloor \cdot 2^p$
+
+\smallskip
+
+\quad while $pos > 0$
+
+\qquad if {\em sector at pos} is a valid ecc header: STOP.
+
+\qquad if {\em sector at pos} is unreadable, set $pos := pos - 2^p$ .
+
+\hspace*{13mm} Continue with inner while loop.
+
+\qquad if {\em sector at pos} is readable and not a ecc header, set $p := p -1$ .
+
+\hspace*{13mm} Continue with outer while loop.
+
+\bigskip
+
+In order to test for a valid ecc header, check that {\em ec-$>$cookie}
+equals the 16-byte string ``*dvdisaster*RS02''. Then check that the
+CRC32 sum of the ecc header matches the value recorded in {\em eh-$>$selfCRC},
+with {\em eh-$>$selfCRC} set to the byte sequence 0x47,0x50,0x4c,0x00
+for the purpose of calculating the CRC32 sum.
+
+\medskip
+
+Please notice that during testing of the sectors at multiples of $2^{(p-1)}$,
+all sectors previously tested for $2^p$ will be examined again. It is therefore
+highly recommended to cache results from previous iterations of the outer
+while loop, especially when reading sectors from the optical medium.
+
+
+
+\subsection{Sector addressing and initialization scheme}
+\label{addressing-two}
+
+For encoding and decoding purposes it is required to retrieve the
+{\em i-th} sector from the {\em j-th} data or ecc layers, e.g. to calculate
+the corresponding sector number in the augmented image. 
+The reverse calculation is also needed, e.g. to calculate the
+corresponding layer and sector index for a given sector number
+in the augmented image.
+
+\smallskip
+
+Bear in mind that as shown in figure \ref{layout-logical-two}, an augmented image 
+is divided into two logical parts. There is a data area containing 
+the .iso image contents, the first ecc header and the CRC checksums.
+The data area is protected by the parity in the ecc area, which contains
+the parity data interleaved with copies of the ecc header. 
+
+\smallskip
+
+In order to carry out the calculations described below, the following
+values from the layout calculation (see section \ref{calc-two} are required:
+
+\bigskip
+
+\begin{tabular}{lp{10cm}}
+{\em protected sectors} & the size of the data part in sectors \\
+{\em layer size} & the number of sectors per layer \\
+{\em $2^p$} & the modulo value for locating ecc header copies \\
+\end{tabular}
+
+\paragraph{Converting (layer, sector index) pairs into image sector numbers.}
+
+The {\em i-th} sector of data layer {\em j} has the following address $s$ in the image:
+
+\[s = j \cdot layer\; size + i\]
+
+If $s >= protected\; sectors$, $s$ is a padding sector which must not be read 
+from the image file, but created in memory (see the paragraph on initialization below).
+
+\bigskip
+
+To calculate the sector address $es$ of the {\em i-th} sector from the {\em j-th} 
+ecc layer, the non-linear mapping of the ecc sectors has to be taken into account.
+The index of the first interleaved ecc header is:
+
+\[ first\; interleaved = \left\lceil\frac{protected\; sectors}{2^p}\right\rceil \cdot 2^p\]
+
+Since {\em protected sectors} is equal to the address of the first ecc sector in the image,
+the amount of ecc sectors before the first interleaved ecc header is:
+
+\[ base\; ecc\; sectors = first\; interleaved - protected\; sectors\]
+
+The ecc sector we are looking for would have the following index if ecc
+sectors were linearly mapped:
+
+\[ ecc\; index = j \cdot layer\; size + i\]
+
+If {\em ecc index $<$ base ecc sectors}, $es$ = {\em protected sectors} + {\em ecc index}.
+Otherwise, the non-linear mapping must be taken into account. The number of interleaved
+ecc headers before the (currently unknown) sector position $es$ is:
+
+\[ interleaved\; headers = \left\lfloor\frac{ecc\; index - base\; ecc\; sectors}{2^p - 2}\right\rfloor \]
+
+Therfore the position of the ecc sector in the augmented image is:
+
+\[ es = protected\; sectors + ecc\; index + 2 \cdot interleaved\; headers + 2 \] 
+
+\paragraph{Example.} To continue the example from section \ref{example-two}, the
+position of the 17th ecc sector in the 3rd ecc layer shall be computed. The relevant
+layout values are:
+
+\smallskip
+
+\begin{center}
+\begin{tabular}{rll}
+{\em protected sectors} & = & 295.579 \\
+{\em layer size} & = & 1.408 \\
+{\em $2^p$} & = & 2.048 \\
+\end{tabular}
+\end{center}
+
+The first interleaved ecc header is at position:
+
+\[ first\; interleaved = \left\lceil\frac{295.579}{2.048}\right\rceil \cdot 2.048 = 296.960 \]
+
+Before the first interleaved ecc header,
+
+\[ base\; ecc\; sectors = 296.960 - 295.579 = 1.381 \]
+
+ecc sectors have been stored. The linear index of the sought ecc sector is:
+
+\[ ecc\; index = 3 \cdot 1.408 + 17 = 4.241 \]
+
+Since 4.241 $\ge$ 1.381, the embedded ecc headers must be taken into account. There are
+
+\[ interleaved \; headers = \left\lfloor\frac{4.241 - 1.381}{2.048-2}\right\rfloor = 1 \]
+
+interleaved ecc headers, each containing 2 physical sectors. Therefore the position
+of the sought ecc sector in the image is:
+
+\[ es = 295.579 + 4.241 + 2 + 2 = 299.824 \]
+
+\bigskip
+
+{\bf Converting image sector numbers into (layer, sector index pairs).}
+
+\smallskip
+
+If the sector number $s$ $<$ {\em protected sectors}, the sector will map to the data part
+as follows:
+
+\[layer = \left\lfloor s\; /\; layer\;size \right\rfloor\]
+\[i = s \bmod layer\;size\]
+
+Otherwise, the mapping to the ecc part is calculated as follows. The index of the first interleaved ecc header is:
+
+\[ first\; interleaved = \left\lceil\frac{protected\; sectors}{2^p}\right\rceil \cdot 2^p\]
+
+If $s\; mod\; 2^p \le 1$, the sector maps to the {\em n-th} interleaved ecc header, with:
+
+\[n = \left\lfloor\frac{s - first\; interleaved}{2^p}\right\rfloor\] 
+
+If $s < first\; interleaved$, the sector is an ecc parity sector with the following mapping:
+
+\[ layer = \left\lfloor(s - protected\; sectors)\; /\; layer\; size\right\rfloor\]
+\[ i = (s - protected\; sectors)\; mod\; layer\;size\]
+
+If $s \ge first\; interleaved$, the mapping of the ecc parity sector is calculated as follows:
+
+The amount of ecc sectors before the first interleaved ecc header is:
+
+\[ base\; ecc\; sectors = first\; interleaved - protected\; sectors\]
+
+The number of interleaved ecc headers before sector $s$ is:
+
+\[ interleaved\; headers = \left\lfloor\frac{s - first\; interleaved - 2}{2^p}\right\rfloor \]
+
+If ecc sectors were mapped linearly, then $s$ had the linear index:
+
+\[ ecc\; index = s - protected\; sectors - 2 \cdot interleaved\; headers - 2\]
+
+Finally, this means that $s$ maps to the following parity sector:
+
+\[ layer = \left\lfloor ecc\; index\; /\; layer\; size\right\rfloor \]
+\[ i = ecc\;index \bmod layer\; size \]
+
+\paragraph{Padding sectors.} Let {\em iso image size} be the size of the
+.iso image prior to augmenting it with error correction data. In order
+to augment the image with error correction sectors, the following
+sectors are treated as padding sectors which are filled with zeroes:
+
+\begin{itemize}
+\item All sectors $s$ $>$ {\em protected sectors}.
+\item The first ecc header (sectors $iso\; image\; size$ and $iso\; image\; size+1$).
+\end{itemize}
+ 
+The first ecc header sectors must be treated as padding to break a circular
+dependency with the parity bytes; as the ecc header contains a md5 sum over
+all parity bytes, it can not be used as input for the parity generation.
+
+\subsection{Encoding the checksums}
+\label{crc-two}
+
+For each sector of the .iso image a CRC32 checksum is calculated and stored in the
+data part of the augmented image (see fig. \ref{layout-logical-two}). By using the
+conventions of section \ref{sec-layout-logical-two}, let $d_{i,j}$ be the $i$-th byte
+of the $j$-th data layer and $c(y,j)$ the 4-byte checksum of the $y$-th sector
+in the $j$-th data layer. Then $c(y,j)$ = CRC32($d_{2048*y,j}$, $d_{2048*y+1,j}$, \dots, $d_{2048*y+2047,j}$).  
+

+\smallskip
+
+A total of $\left\lceil\frac{iso\; image\; size}{512}\right\rceil$ sectors holding the

+and there are $layer\; size$ blocks of checksums total. Checksum generation does not start with
+layer sector $0$, but rather with layer sector $first\; layer\; crc\; idx$. Subsequent blocks
+are generated in ascending layer sector order {\em modulo layer size} so that all
+{\em layer  size} layer sector positions are eventually covered. 
+This scheme produces the following
+sequence of checksums:

+
+$^{*)}$ The last sectors of each data layer may be padding sectors. For those padding
+sectors, {\em no} CRC32 checksums are generated and stored (e.g. the number of
+generated checksums is always exactly {\em iso image size}).
+
+Since {\em iso image size} is usually not a multiple of 512, the last sector in
+the data part may only be partially filled with checksum data. The remaining
+bytes of this sector must be filled with the repeated byte sequence
+0x47,0x50,0x4c,0x00 which is the ASCII string representation of the text ``GPL''.
+
+\smallskip
+
+A copy of the CRC32 sums for the layer sectors at position ($first\; layer\; crc\; idx \bmod layer\; size$)
+is stored in the ecc header, starting there at byte position 2048. This has the advantage that
+the CRC checksums are already available for the {\em first layer crc}-th sectors
+of data layers $1,\ldots,n$. Any corrupted bytes in those sectors are
+detected by the CRC32 and can be handled by the error correction in erasure mode,
+saving precious parity bytes. When the error correction has restored all sectors
+of the {\em first layer crc}-th ecc block, note that the {\em first layer crc}-th
+sector of data layer $n$ will contain the CRC32 checksums for the data sectors 
+in the next ecc block ({\em first layer crc + 1}). Therefore the layout is robust
+against loss of CRC sectors as they are restored by the error correction just
+before they are actually needed.
+
+\subsection{Encoding the ecc layers}
+\label{encoding-two}
+
+Encoding the ecc layers requires the following steps:
+
+\medskip
+
+First the image must be examined whether it does already contain
+augmented ecc data (either RS02 or RS03). If ecc data is found, the
+image must be stripped to the original size of the .iso image. 
+Nesting ecc data is not supported by the current codecs and it
+might derail the heuristics for detecting the augmented data
+properly. From a technical point, nesting ecc data does not
+make sense either.
+
+\medskip
+
+Next the image must be checked for missing sectors, and be rejected
+if it is incomplete. Producing and
+writing images with missing sectors to a medium is
+confusing to the user as dvdisaster will always report 
+the medium as partially readable even though it does not contain
+any physical defects. Also the error correction will never
+succeed for such media as it is just restoring the sector
+in its missing  state. 
+During the check for missing sectors the CRC32 checksums 
+of each sector can be computed as described in section \ref{crc-two} and, 
+after writing a placeholder for the first ecc header, be appended to the image.
+Also, the MD5 sum of the .iso image can be calculated at this time and
+kept for insertion into the ecc header field {\em ec-$>$mediumSum}.
+As another step of preparation, enough space should be appended
+to the image to store the ecc layer sectors. This makes sure
+that the encoder does not run out of disk space during
+its potentially lenghty work, and minimizes the impact of
+fragmentation due to random writes into the appended 
+image area under most file systems.
+
+\medskip
+
+Finally, the error correction information needs to be encoded.
+Please refer to fig. \ref{layout-logical-two} on the location
+of the bytes comprising an error correction block.
+Although the ecc blocks could be encoded by a byte-wise scheme, 
+a possible encoding algorithm would preferably buffer at least the 
+255 sectors holding the required data for 2048 subsequent ecc
+blocks, and process those in bulk. From the first $n$ data layers,
+the required bytes are retrieved and fed into the RS(255,k)
+Reed-Solomon encoder, with $k = 255 -n$. The RS(255,k) encoder 
+is the same for RS01, RS02 and RS03. See
+appendix \ref{rs} for the parameters used in the encoder.
+ 
+Please refer to
+the previous section on information about zeroed-out and
+zero-padded data sectors. The resulting $k$ parity bytes
+are distributed into the $k$ ecc layers. When writing out
+the ecc data into the image, free gaps must be left for
+the interleaved ecc headers; see section
+\ref{addressing-two} for information on calculating the
+interleaved ecc header positions. At this time, the MD5
+sums of each ecc layer can be updated incrementally. 
+
+\medskip
+
+When all parity sectors have been calculated, the ecc headers
+can be completed by filling in their {\em eh-$>$eccSum} field.
+This field contains the MD5 sum calculated over the MD5 sums
+over each of the $k$ ecc layers. In contrast to a single MD5
+sum spanning the ecc layers in a linear fashion, this
+approach allows for an incremental calculation of the MD5 sum
+while the ecc data is generated and written out.

+\section{The RS03 codec}

+
+This section describes the data format of the dvdisaster RS03 Reed-Solomon codec.
+RS03 can store parity data either in a separate file or append it to the .iso
+image on the same medium. In contrast to its predecessors RS03 is fully multi-threadable.
+RS03  is expected to become the default codec soon after its introduction in 
+dvdisaster 0.80.
+
+\subsection{Physical layout}
+
+Optical media are recorded as a single long spiral\footnote{Multiple layered
+media contain one spiral for each physical layer, but are otherwise conceptually
+identical.} of sectors which are indexed beginning with 0. 
+The first sector lies at the innermost position of the spiral and 
+numbering continues onward to the outside of the spiral.
+
+Reed-Solomon encoding works best when errors are evenly distributed over
+all ecc blocks. Therefore we must strive to spread our ecc blocks evenly over
+the media surface. To facilitate such distribution, dvdisaster logically
+divides the medium into 255 units which are called ``layers'' for historical reasons.
+Figure \ref{layout-phy} illustrates how a medium is divided into $n$ data layers,
+one CRC layer, and $m$ ecc layers, with $n+m+1 = 255$. Ecc blocks are comprised
+by taking one byte from each layer as shown in fig. \ref{layout-logical} on 
+the following page.
+This distributes the ecc block reasonably good 
+over the medium surface.
+
+Layer size is measured in numbers of sectors which are 2048 bytes in size. All
+255 layers have the same size. The data layers map exactly 
+to the iso image which is to be protected by dvdisaster; 
+e.g. the number and sequence of sectors in $Data_1,\ldots,Data_n$
+is the same as in the iso image. Two extra sectors are appended to the ISO image
+holding the ecc header ``EH''; these are logically treated as a part of the ISO image.
+If the ISO image size plus the two EH headers is not an integer multiple
+of the layer size, the last (n-th) data layer will be padded accordingly.  
+
+The data layers are followed by a CRC layer. Each CRC layer sector contains a
+data structure holding CRC32 checksums for the data sectors plus additional
+parameters which were used during the RS03 encoding process.
+The data and CRC layers are protected by the
+Reed-Solomon parity which is stored in the remaining layers ($ECC_1,\ldots,ECC_m$).
+Since the medium capacity is not necessarily an integer multiple of 255, some
+unused sectors remain at the end of the medium. These are neither written nor
+referenced in any way.
+
+\smallskip
+
+The RS03 data can be stored either directly on the medium or into a separate file.
+Figure \ref{layout-phy} shows the first case where ecc data is embedded into the
+image; this is also called a ``RS03 augmented ISO image'' in dvdisaster
+terminology. 
+In the other case a separate error correction file will be created containing
+the sectors starting with the EH header. The following discussion is based
+on the augmented image case; see section \ref{eccfile} for handling the
+file based format.
+
+\subsection{Logical layout}
+
+\begin{figure}
+ \begin{center}
+ \includegraphics[width=\textwidth]{layer.eps}
+ \caption{Logical RS03 layout}
+ \label{layout-logical}
+ \end{center}
+\end{figure}
+
+
+The relationship between layers and ecc blocks is stated again in the
+logical view presented in figure \ref{layout-logical}. Here the 255 layers are
+shown in stacked order. From each layer the $i-th$ byte corresponds to the
+$i-th$ error correction block. The parity is calculated using $n$ data bytes
+$d_{i,1},\ldots,d_{i,n}$ plus the crc byte $c_i$. The resulting $m$ roots of 
+the completed Reed-Solomon code are then stored in the 
+ecc bytes $e_{i,1},\ldots, e_{i,m}$. 
+
+Since the input iso image plus the two EH sectors is usually not an integer 
+multiple of the layer size, the last data layer $data_n$ may contain padding
+sectors containing a special signature. The content of the padding sectors
+is used in the ecc byte calculation and is written into the augmented image.
+
+\subsection{Calculating the layout for encoding}
+
+\begin{table}
+ \begin{center}
+ \begin{tabular}{|lrr|}
+ \hline
+ Medium type &  Maximum size & Layer size \\
+ \hline
+ CD & 359.424 & 1.409 \\
+ DVD 1 layer & 2.295.104 & 9.000 \\
+ DVD 2 layers & 4.171.712 & 16.359 \\
+ BD 1 layer & 11.826.176 & 46.377 \\
+ BD 2 layers & 23.652.352 & 92.754 \\
+ \hline
+ \end{tabular}
+ \caption{Sector size parameters for several media types}
+ \label{layout-size-table}
+ \end{center}
+\end{table}
+
+When encoding with RS03 the layout of the augmented image is fully specified
+by two values: the maximum medium size and the iso image size
+(from now on, ``size'' always means ``number of 2048K sectors''). \bigskip
+
+Media sizes are hard coded and taken from table \ref{layout-size-table}. Since we need to divide the medium into 255 layers, the layer size
+is:
+ 
+\[layer\ size = \left\lfloor\frac{medium\ size}{255}\right\rfloor\]
+
+This allows us to compute the number of data layers needed to cover the iso image plus the ecc header:
+
+\[data\ layers =  \left\lceil\frac{iso\ image\ size + 2}{layer\ size}\right\rceil\]
+
+The number of padding sectors in the last data layer is:
+
+\[padding\ sectors = layer\ size * data\ layers - iso\ image\ size - 2\]
+
+For Reed-Solomon encoding, we will have to encode 
+
+\[n\ data\ bytes = data\ layers + 1\]
+
+and produce the following number of parity bytes:
+
+\[m\ roots = 255 - n\ data\ bytes\]
+
+The RS03 augmented image must fill the medium completely (except for the 
+$medium\ size \bmod 255$ sectors  at the end). However for performance
+reasons the maximum redundancy is capped to 200\%, or 170 roots. This means
+that the ISO image must at least span the first 255-170=85 layers, otherwise
+additional padding will be added to fill up the 85 data layers. This situation
+is not reflected in the calculations and figure shown above.
+
+\subsection{Re-calculating the layout from defective media}
+\label{recover}
+
+In order to recover a defective medium, the values of {\em layer size}
+and {\em data layers} need to be determined. The RS03 format allows
+for three heuristics with increasing complexity for learning about these
+values:
+
+\subsubsection{Using the Ecc Header}
+
+All required information can be obtained from the data structures of the
+Ecc Header which is described in appendix \ref{eh}. 
+If ecc data is stored in a separate error correction
+file, the first 4096 bytes of the ecc file yield the Ecc Header.
+Otherwise, let $n$ be the size of the ISO file system which
+can be obtained from the ISO file system master block. Then the 
+Ecc Header is typically found in the RS03-augmented image at sectors $n,n+1$ 
+or at $n+150,n+151$ (due to padding inserted by some popular CD-R  mastering
+software). \smallskip
+
+If the ISO file system master block is unreadable, the Ecc Header
+can be identified by its characteristic signature and checksum. 
+If the Ecc Header is encountered during reading of the defective medium 
+it might be worthwhile to generate a tentative ISO master block in the image
+file. This would speed up future processing of the image; however current
+implementations of dvdisaster do not yet implement this feature.
+
+\subsubsection{Using the CRC layer}
+
+Each CRC layer sector contains a data structure which not only holds the
+CRC32 checksums but also a copy of important parameters from the Ecc header
+(see section \ref{crc} for details). CRC sectors can be easily recognized
+by looking for their signature and checksum while scanning the medium image.
+If dvdisaster finds a valid CRC sector and the Ecc header is defective,
+a tentative Ecc header is written to the image to speed up further
+operations on the image file.
+
+However it should be noted that since all CRC sectors are stored 
+consecutively on the medium, they can easily be wiped out by a large
+defective region on the medium. Therefore, another heuristic exists
+for learning about the RS03 layout.
+
+\subsubsection{Evaluating the Reed-Solomon code}
+\label{recover-rs}
+
+If neither the Ecc Header nor any CRC sectors are readable
+the RS03 layout can be determined by the following heuristic.
+
+First, the medium size is determined from table \ref{layout-size-table}.
+This is always possible as long as the drive will recognize the medium at all.
+Since the layer size is $\left\lfloor\frac{medium\ size}{255}\right\rfloor$,
+the location of the 255 layers on the medium is now known. The remaining task is to find
+out the redundancy of the Reed-Solomon code, e.g. how many layers contain
+roots for the RS code.
+
+\bigskip
+
+Taking the {\em i-th} sector from each layer will produce a valid error 
+correction block, but with unknown redundancy. As RS03 will create redundancies 
+using 8 to 170 roots, we employ a brute-force approach by evaluating
+the Reed-Solomon code for $8..170$ roots. If the error correction
+is successful for $n$ roots and the sector from layer {\em 255-1-n} yields
+the CRC data structure, the correct number of roots has been found.
+
+\medskip
+
+In reality, not all 162 combinations of roots need to tested since additional
+information can be exploited:
+
+\begin{enumerate}
+\item If the sector from layer {\em 255-1-n} is present/readable,
+we do not need to test for $n$ roots any further: Encoding with $n$ roots would
+have produced a CRC sector in this place.
+\item If the number of erasures (as indicated by unreadable sectors) is higher
+than $n$, we can trivially skip the RS decoding. We might have to test another
+set of 255 sectors though if testing for all other numbers of roots fails as well.
+\end{enumerate}
+
+Criterion 1) should quickly narrow down the possible numbers of roots
+in the average case, e.g. when enough redundancy is available for recovering the medium.
+Worst case behaviour of trying each ecc block for 8..170 roots is likely to appear only
+when the medium is unrecoverable, e.g. when more sectors are damaged than the 
+Reed-Solomon code can correct.
+
+\subsection{Contents of the CRC layer}
+\label{crc}
+
+Each sector of the CRC layer contains the data structure shown in
+appendix \ref{crc-block}. Following the numbering from figure \ref{layout-logical},
+CRC sector $c_i$ contains the CRC32 checksums for data sectors $d_{j,1},\ldots,d_{j,n}$
+with $j = (i+1)\bmod\ layer\ size$. The purpose of this offset is to have
+the error correction of ECC block $i$ recover the CRC checksum for the next 
+ECC block $i+1$. In case of readable but corrupted sectors this will keep the
+error correction in erasure mode and therefore save precious redundancy (the
+RS code can recover twice as much errors when the location of defective data
+is known). \medskip
+
+Checksums for data sector $d_{j,k}$ are stored in array element
+CrcBlock-$>$crc[k]. Unused array elements are set to zero.
+The remaining contents of the CRC sector structure provide 
+configuration and layout information; see appendix \ref{crc-block} for details.
+
+\subsection{Encoding the ecc layers}
+
+Encoding the error correction information
+ requires reading and buffering of at least
+255 sectors comprising the ecc block
+(see fig. \ref{layout-logical} for a definition of the ecc block).
+A possible encoding algorithm
+might process each ecc block at a time. For each ecc block $i$
+it would do the following: \smallskip
+
+First, the $n$ data sectors $d_{i,1},\ldots,d_{i,n}$ of the ecc block
+are read in. The CRC layer 
+sector $c_i$ is initialized, filled in with checksums 
+generated by processing the previous ecc block, and completed
+by calculating its own checksum {\em selfCRC}. Unused portions of $c_i$
+remain zero. Afterwards the
+CRC32 checksums of $d_{i,1},\ldots,d_{i,n}$ are calculated
+and stored away using the same buffering mechanism. Since the hand-over of
+CRC checksums between ecc blocks is the only place where RS03 does 
+not fully parallelize, data sector I/O and CRC32 caching needs to be 
+carefully thought out in multithreaded implementations. \medskip
+
+
+Once $d_{i,1},\ldots,d_{i,n}$ and $c_i$ have been prepared, 
+2048 sets of a  RS(255,k) code (with $k=255-n-1$) are calculated by 
+looping over the 2048 bytes of the ecc sectors. If $l$ denotes
+a certain byte position between $0,\ldots,2047$ in the ecc block
+sectors, then the {\em l-th} byte from $d_{i,1},\ldots,d_{i,n},c_i$
+is retrieved and fed into the RS(255,k) encoder. The resulting
+parity bytes $p_1,\ldots,p_m$ are stored in byte position $l$ of the
+ecc layer sectors $e_{i,1},\ldots,e_{i,m}$. When all 2048 bytes
+of the ecc block sectors have been processed the ecc layer sectors
+can be written out; either into the error correction file or into
+the RS03 augmented image. \medskip
+
+The RS(255,k) encoder is the same for RS01, RS02 and RS03. See
+appendix \ref{rs} for the parameters used in the encoder.
+
+\subsection{Encoding as a separate error correction file}
+\label{eccfile}
+
+If the image size is too close to the medium capacity, not enough
+space is left for augmenting the image with redundancy. dvdisaster
+will refuse to augment images when there is insufficient space
+for at least 8 roots. Creating images with less than 43 roots
+(20\% of redundancy) will trigger a warning that the error correction
+capacity may be too low. In those cases, storing the error correction
+information in a separate file comes as an alternative.
+
+\medskip
+
+RS03 error correction files (``ecc files'')
+contain the same error correction information
+and layout as in the augmented image case, with the following differences:
+
+\paragraph{Omittance of data padding sectors.} While the image format
+shown in figures \ref{layout-phy} and \ref{layout-logical}
+ may contain padding sectors between the ecc header and the CRC layer,
+those sectors are not written into the ecc file.
+The padding sectors are however required during encoding and
+decoding, e.g. they need to be virtually created in memory 
+when processing the respective ecc blocks. 
+Therefore an ecc file providing {\em nroots} of redundancy
+will contain {\em 2 + (nroots+1) * layer size} sectors.
+Physically it will contain the ecc header, then the CRC layer 
+and finally the {\em nroots} ecc layers. In contrast to the
+augmented image case, the ecc header {\em is not part of an ecc
+  block} and can therefore not be recovered
+by the error correction. If the ecc header is lost in an ecc file,
+its contents can be reconstructed from a still existing block
+in the CRC layer and then be rewritten accordingly.
+
+\paragraph{Freely chooseable redundancy.} In the augmented image case
+the redundancy is always chosen to fill up the medium completely.
+For ecc files the redundancy can be freely chosen by the user between
+ 8 roots (3.2\%) and 170 roots (200\%). Encoding with more than 170 roots
+is technically possible, but run-time requirements get out of proportion;
+hence the selectable redundancy is capped at 200\%.
+
+\medskip
+
+As a consequence of the variable redundancy the ecc file layout can only
+be determined by looking at the ecc header or CRC sectors. The strategy
+of experimentally evaluating the Reed-Solomon code (see sub 
+section \ref{recover-rs}) however can not be applied to ecc files since
+neither the size of the padding area nor the original size of the 
+possibly truncated image and ecc files can be determined. \medskip
+
+To see whether this is really a limiting factor we look
+at the typical outcome of recovering a single file from a defective
+medium:
+
+\begin{itemize}
+\item The ecc file is fully read, but random sectors are damaged.
+\item The ecc file is truncated to the position of the first read error.
+\end{itemize}
+
+In both scenarios it is highly likely that at least one CRC sector survives
+at the beginning of the file; in that case the error correction will not
+only recover the image but also repair the ecc file into its original state.
+
+\bigskip
+
+Although this gives RS03 ecc files good chances to remain functional even
+when being partly damaged, it is highly recommended to store ecc files 
+only on media which are themself being protected by dvdisaster. 
+ISO and UDF file systems
+do not have sufficient redundancy for their meta data (e.g. directory
+structures). If such meta data becomes unreadable a significant
+number of files may become completely inaccessible. 
+Please note that this is a
+general weakness of file-based data protection and recovery: The
+meta data is not part of any file and can therefore not be protected by
+any error correction data put inside the file(s). 
+\smallskip
+This is the also the simple reason why we did not use tools like PAR2 
+and developed dvdisaster instead; 
+the image-based approach of dvdisaster protects
+both files and meta data.
