-                    GNU GENERAL PUBLIC LICENSE
-                       Version 2, June 1991
-
- Copyright (C) 1989, 1991 Free Software Foundation, Inc.,
- 51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            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 Lesser General Public License instead.)  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.
-
-  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.
-
-  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.
-
-  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.
-
-  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.
-
-  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.
-
-  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".
-
-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.
-
-  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.
-
-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.
-
-  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:
-
-    a) You must cause the modified files to carry prominent notices
-    stating that you changed the files and the date of any change.
-
-    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.
-
-    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.
-
-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.
-
-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.
-
-  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:
-
-    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,
-
-    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,
-
-    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 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.
-
-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.
-
-  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.
-
-  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
-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
-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.
-
-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.
-
-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.
-
-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.
-
-  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
-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.
-
-  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.
-
-                            NO WARRANTY
-
-  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
-PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY OF ANY KIND, EITHER EXPRESSED
-OR IMPLIED, INCLUDING, BUT NOT LIMITED TO, THE IMPLIED WARRANTIES OF
-MERCHANTABILITY AND FITNESS FOR A PARTICULAR PURPOSE.  THE ENTIRE RISK AS
-TO THE QUALITY AND PERFORMANCE OF THE PROGRAM IS WITH YOU.  SHOULD THE
-PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF ALL NECESSARY SERVICING,
-REPAIR OR CORRECTION.
-
-  12. IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MAY MODIFY AND/OR
-REDISTRIBUTE THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES,
-INCLUDING ANY GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING
-OUT OF THE USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED
-TO LOSS OF DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY
-YOU OR THIRD PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER
-PROGRAMS), EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE
-POSSIBILITY OF SUCH DAMAGES.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-convey the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software; you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation; either version 2 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License along
-    with this program; if not, write to the Free Software Foundation, Inc.,
-    51 Franklin Street, Fifth Floor, Boston, MA 02110-1301 USA.
-
-Also add information on how to contact you by electronic and paper mail.
-
-If the program is interactive, make it output a short notice like this
-when it starts in an interactive mode:
-
-    Gnomovision version 69, Copyright (C) year name of author
-    Gnomovision comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, the commands you use may
-be called something other than `show w' and `show c'; they could even be
-mouse-clicks or menu items--whatever suits your program.
-
-You should also get your employer (if you work as a programmer) or your
-school, if any, to sign a "copyright disclaimer" for the program, if
-necessary.  Here is a sample; alter the names:
-
-  Yoyodyne, Inc., hereby disclaims all copyright interest in the program
-  `Gnomovision' (which makes passes at compilers) written by James Hacker.
-
-  <signature of Ty Coon>, 1 April 1989
-  Ty Coon, President of Vice
-
-This General Public License does not permit incorporating your program into
-proprietary programs.  If your program is a subroutine library, you may
-consider it more useful to permit linking proprietary applications with the
-library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.

-                    GNU GENERAL PUBLIC LICENSE
-                       Version 3, 29 June 2007
-
- Copyright (C) 2007 Free Software Foundation, Inc. <http://fsf.org/>
- Everyone is permitted to copy and distribute verbatim copies
- of this license document, but changing it is not allowed.
-
-                            Preamble
-
-  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
-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 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 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.
-
-  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.
-
-  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.
-
-  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.
-
-                       TERMS AND CONDITIONS
-
-  0. Definitions.
-
-  "This License" refers to version 3 of the GNU General Public License.
-
-  "Copyright" also means copyright-like laws that apply to other kinds of
-works, such as semiconductor masks.
-
-  "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.
-
-  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.
-
-  A "covered work" means either the unmodified Program or a work based
-on the Program.
-
-  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.
-
-  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.
-
-  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.
-
-  1. Source Code.
-
-  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.
-
-  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.
-
-  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 "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.
-
-  The Corresponding Source need not include anything that users
-can regenerate automatically from other parts of the Corresponding
-Source.
-
-  The Corresponding Source for a work in source code form is that
-same work.
-
-  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.
-
-  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 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.
-
-  13. Use with the GNU Affero General Public License.
-
-  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.
-
-  14. Revised Versions of this License.
-
-  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 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.
-
-  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.
-
-  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.
-
-  15. Disclaimer of Warranty.
-
-  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 PROVIDE THE PROGRAM "AS IS" WITHOUT WARRANTY
-OF ANY KIND, EITHER EXPRESSED OR IMPLIED, INCLUDING, BUT NOT LIMITED TO,
-THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR
-PURPOSE.  THE ENTIRE RISK AS TO THE QUALITY AND PERFORMANCE OF THE PROGRAM
-IS WITH YOU.  SHOULD THE PROGRAM PROVE DEFECTIVE, YOU ASSUME THE COST OF
-ALL NECESSARY SERVICING, REPAIR OR CORRECTION.
-
-  16. Limitation of Liability.
-
-  IN NO EVENT UNLESS REQUIRED BY APPLICABLE LAW OR AGREED TO IN WRITING
-WILL ANY COPYRIGHT HOLDER, OR ANY OTHER PARTY WHO MODIFIES AND/OR CONVEYS
-THE PROGRAM AS PERMITTED ABOVE, BE LIABLE TO YOU FOR DAMAGES, INCLUDING ANY
-GENERAL, SPECIAL, INCIDENTAL OR CONSEQUENTIAL DAMAGES ARISING OUT OF THE
-USE OR INABILITY TO USE THE PROGRAM (INCLUDING BUT NOT LIMITED TO LOSS OF
-DATA OR DATA BEING RENDERED INACCURATE OR LOSSES SUSTAINED BY YOU OR THIRD
-PARTIES OR A FAILURE OF THE PROGRAM TO OPERATE WITH ANY OTHER PROGRAMS),
-EVEN IF SUCH HOLDER OR OTHER PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF
-SUCH DAMAGES.
-
-  17. Interpretation of Sections 15 and 16.
-
-  If the disclaimer of warranty and limitation of liability provided
-above cannot be given local legal effect according to their terms,
-reviewing courts shall apply local law that most closely approximates
-an absolute waiver of all civil liability in connection with the
-Program, unless a warranty or assumption of liability accompanies a
-copy of the Program in return for a fee.
-
-                     END OF TERMS AND CONDITIONS
-
-            How to Apply These Terms to Your New Programs
-
-  If you develop a new program, and you want it to be of the greatest
-possible use to the public, the best way to achieve this is to make it
-free software which everyone can redistribute and change under these terms.
-
-  To do so, attach the following notices to the program.  It is safest
-to attach them to the start of each source file to most effectively
-state the exclusion of warranty; and each file should have at least
-the "copyright" line and a pointer to where the full notice is found.
-
-    <one line to give the program's name and a brief idea of what it does.>
-    Copyright (C) <year>  <name of author>
-
-    This program is free software: you can redistribute it and/or modify
-    it under the terms of the GNU General Public License as published by
-    the Free Software Foundation, either version 3 of the License, or
-    (at your option) any later version.
-
-    This program is distributed in the hope that it will be useful,
-    but WITHOUT ANY WARRANTY; without even the implied warranty of
-    MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.  See the
-    GNU General Public License for more details.
-
-    You should have received a copy of the GNU General Public License
-    along with this program.  If not, see <http://www.gnu.org/licenses/>.
-
-Also add information on how to contact you by electronic and paper mail.
-
-  If the program does terminal interaction, make it output a short
-notice like this when it starts in an interactive mode:
-
-    <program>  Copyright (C) <year>  <name of author>
-    This program comes with ABSOLUTELY NO WARRANTY; for details type `show w'.
-    This is free software, and you are welcome to redistribute it
-    under certain conditions; type `show c' for details.
-
-The hypothetical commands `show w' and `show c' should show the appropriate
-parts of the General Public License.  Of course, your program's commands
-might be different; for a GUI interface, you would use an "about box".
-
-  You should also get your employer (if you work as a programmer) or school,
-if any, to sign a "copyright disclaimer" for the program, if necessary.
-For more information on this, and how to apply and follow the GNU GPL, see
-<http://www.gnu.org/licenses/>.
-
-  The GNU General Public License does not permit incorporating your program
-into proprietary programs.  If your program is a subroutine library, you
-may consider it more useful to permit linking proprietary applications with
-the library.  If this is what you want to do, use the GNU Lesser General
-Public License instead of this License.  But first, please read
-<http://www.gnu.org/philosophy/why-not-lgpl.html>.

-ZeroTier - A Planetary Ethernet Switch
+ZeroTier - Global Area Networking
 ======
 
-ZeroTier is a smart programmable Ethernet switch for planet Earth.
+ZeroTier is a smart programmable Ethernet switch for planet Earth. It allows all networked devices, VMs, containers, and applications to communicate as if they all reside in the same physical data center or cloud region.
 
-It replaces the physical LAN/WAN boundary with a virtual one, allowing devices of any type at any location to be managed as if they all reside in the same cloud region or data center. All traffic is encrypted end-to-end and takes the most direct path available for minimum latency and maximum performance. The goals and design of ZeroTier are inspired by among other things the original [Google BeyondCorp](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/43231.pdf) paper and the [Jericho Forum](https://en.wikipedia.org/wiki/Jericho_Forum).
+This is accomplished by combining a cryptographically addressed and secure peer to peer network (termed VL1) with an Ethernet emulation layer somewhat similar to VXLAN (termed VL2). Our VL2 Ethernet virtualization layer includes advanced enterprise SDN features like fine grained access control rules for network micro-segmentation and security monitoring.
 
-Visit [ZeroTier's site](https://www.zerotier.com/?pk_campaign=github_ZeroTierOne) for more information and [pre-built binary packages](https://www.zerotier.com/download.shtml?pk_campaign=github_ZeroTierOne). Apps for Android and iOS are available for free in the Google Play and Apple app stores.
+All ZeroTier traffic is encrypted end-to-end using secret keys that only you control. Most traffic flows peer to peer, though we offer free (but slow) relaying for users who cannot establish peer to peer connetions.
+
+The goals and design principles of ZeroTier are inspired by among other things the original [Google BeyondCorp](https://static.googleusercontent.com/media/research.google.com/en//pubs/archive/43231.pdf) paper and the [Jericho Forum](https://en.wikipedia.org/wiki/Jericho_Forum) with its notion of "deperimeterization."

+ZeroTier is licensed under the [BSL version 1.1](https://mariadb.com/bsl11/). See [LICENSE.txt](LICENSE.txt) and the [ZeroTier pricing page](https://www.zerotier.com/pricing) for details. ZeroTier is free to use internally in businesses and academic institutions and for non-commercial purposes. Certain types of commercial use such as building closed-source apps and devices based on ZeroTier or offering ZeroTier network controllers and network management as a SaaS service require a commercial license.
+
+A small amount of third party code is also included in ZeroTier and is not subject to our BSL license. See [AUTHORS.md] for a list of third party code, where it is included, and the licenses that apply to it. All of the third party code in ZeroTier is liberally licensed (MIT, BSD, Apache, public domain, etc.).
 
 ### Getting Started
 
-Everything in the ZeroTier world is controlled by two types of identifier: 40-bit/10-digit *ZeroTier addresses* and 64-bit/16-digit *network IDs*. A ZeroTier address identifies a node or "device" (laptop, phone, server, VM, app, etc.) while a network ID identifies a virtual Ethernet network that can be joined by devices.
+Everything in the ZeroTier world is controlled by two types of identifier: 40-bit/10-digit *ZeroTier addresses* and 64-bit/16-digit *network IDs*. These identifiers are easily distinguished by their length. A ZeroTier address identifies a node or "device" (laptop, phone, server, VM, app, etc.) while a network ID identifies a virtual Ethernet network that can be joined by devices.
 
-Another way of thinking about it is that ZeroTier addresses are port numbers on a giant planetary-sized smart switch while network IDs are VLANs to which these ports can be assigned. For more details read about VL1 and VL2 in [the ZeroTier manual](https://www.zerotier.com/manual.shtml).
+ZeroTier addresses can be thought of as port numbers on an enormous planet-wide enterprise Ethernet smart switch supporting VLANs. Network IDs are VLAN IDs to which these ports may be assigned. A single port can be assigned to more than one VLAN.
 
-*Network controllers* are ZeroTier nodes that act as access control certificate authorities and configuration managers for virtual networks. The first 40 bits (or 10 digits) of a network ID is the ZeroTier address of its controller. You can create networks with our [hosted controllers](https://my.zerotier.com/) and web UI/API or [host your own](controller/) if you don't mind posting some JSON configuration info or writing a script to do so.
+A ZeroTier address looks like `8056c2e21c` and a network ID looks like `8056c2e21c000001`. Network IDs are composed of the ZeroTier address of that network's primary controller and an arbitrary 24-bit ID that identifies the network on this controller. Network controllers are roughly analogous to SDN controllers in SDN protocols like [OpenFlow](https://en.wikipedia.org/wiki/OpenFlow), though as with the analogy between VXLAN and VL2 this should not be read to imply that the protocols or design are the same. You can use our convenient and inexpensive SaaS hosted controllers at [my.zerotier.com](https://my.zerotier.com/) or [run your own controller](controller/) if you don't mind messing around with JSON configuration files or writing scripts to do so.
 
 ### Project Layout
 
+The base path contains the ZeroTier One service main entry point (`one.cpp`), self test code, makefiles, etc.
+
  - `artwork/`: icons, logos, etc.
  - `attic/`: old stuff and experimental code that we want to keep around for reference.
  - `controller/`: the reference network controller implementation, which is built and included by default on desktop and server build targets.
@@ -28,35 +38,27 @@ Another way of thinking about it is that ZeroTier addresses are port numbers on
  - `macui/`: a Macintosh menu-bar app for controlling ZeroTier One, written in Objective C.

 ### Build and Platform Notes
 
 To build on Mac and Linux just type `make`. On FreeBSD and OpenBSD `gmake` (GNU make) is required and can be installed from packages or ports. For Windows there is a Visual Studio solution in `windows/'.
 
  - **Mac**
-   - Xcode command line tools for OSX 10.7 or newer are required.
-   - Tap device driver kext source is in `ext/tap-mac` and a signed pre-built binary can be found in `ext/bin/tap-mac`. You should not need to build it yourself. It's a fork of [tuntaposx](http://tuntaposx.sourceforge.net) with device names changed to `zt#`, support for a larger MTU, and tun functionality removed.
+   - Xcode command line tools for OSX 10.8 or newer are required.
  - **Linux**
-   - The minimum compiler versions required are GCC/G++ 4.9.3 or CLANG/CLANG++ 3.4.2.
+   - The minimum compiler versions required are GCC/G++ 4.9.3 or CLANG/CLANG++ 3.4.2. (Install `clang` on CentOS 7 as G++ is too old.)
    - Linux makefiles automatically detect and prefer clang/clang++ if present as it produces smaller and slightly faster binaries in most cases. You can override by supplying CC and CXX variables on the make command line.
-   - CentOS 7 ships with a version of GCC/G++ that is too old, but a new enough version of CLANG can be found in the *epel* repositories. Type `yum install epel-release` and then `yum install clang` to build there.
  - **Windows**
    - Windows 7 or newer is supported. This *may* work on Vista but isn't officially supported there. It will not work on Windows XP.
-   - We build with Visual Studio 2015. Older versions may not work. Clang or MinGW will also probably work but may require some makefile hacking.
-   - Pre-built signed Windows drivers are included in `ext/bin/tap-windows-ndis6`. The MSI files found there will install them on 32-bit and 64-bit systems. We don't recommend trying to build Windows drivers from scratch unless you know what you're doing. One does not simply "build" a Windows driver.
+   - We build with Visual Studio 2017. Older versions may not work. Clang or MinGW will also probably work but may require some makefile hacking.
  - **FreeBSD**
-   - Tested most recently on FreeBSD-11. Older versions may work but we're not sure.
-   - GCC/G++ 4.9 and gmake are required. These can be installed from packages or ports. Type `gmake` to build.
+   - GNU make is required. Type `gmake` to build.
  - **OpenBSD**
-   - There is a limit of four network memberships on OpenBSD as there are only four tap devices (`/dev/tap0` through `/dev/tap3`). We're not sure if this can be increased.
-   - OpenBSD lacks `getifmaddrs` (or any equivalent method) to get interface multicast memberships. As a result multicast will only work on OpenBSD for ARP and NDP (IP/MAC lookup) and not for other purposes.
-   - Only tested on OpenBSD 6.0. Older versions may not work.
-   - GCC/G++ 4.9 and gmake are required and can be installed using `pkg_add` or from ports. They get installed in `/usr/local/bin` as `egcc` and `eg++` and our makefile is pre-configured to use them on OpenBSD.
+   - There is a limit of four network memberships on OpenBSD as there are only four tap devices (`/dev/tap0` through `/dev/tap3`).

 Typing `make selftest` will build a *zerotier-selftest* binary which unit tests various internals and reports on a few aspects of the build environment. It's a good idea to try this on novel platforms or architectures.

 Users behind certain types of firewalls and "symmetric" NAT devices may not able able to connect to external peers directly at all. ZeroTier has limited support for port prediction and will *attempt* to traverse symmetric NATs, but this doesn't always work. If P2P connectivity fails you'll be bouncing UDP packets off our relay servers resulting in slower performance. Some NAT router(s) have a configurable NAT mode, and setting this to "full cone" will eliminate this problem. If you do this you may also see a magical improvement for things like VoIP phones, Skype, BitTorrent, WebRTC, certain games, etc., since all of these use NAT traversal techniques similar to ours.
 
-If you're interested, there's a [technical deep dive about NAT traversal on our blog](https://www.zerotier.com/blog/?p=226?pk_campaign=github_ZeroTierOne). A troubleshooting tool to help you diagnose NAT issues is planned for the future as are uPnP/IGD/NAT-PMP and IPv6 transport.

 If a firewall between you and the Internet blocks ZeroTier's UDP traffic, you will fall back to last-resort TCP tunneling to rootservers over port 443 (https impersonation). This will work almost anywhere but is *very slow* compared to UDP or direct peer to peer connectivity.

 ZeroTier Release Notes
 ======
 
+# Version 1.9.0 (2.0 beta)
+
+Version 2.0 is a very significant release with many changes. It remains backward compatibility to version 1.4.0 (and possibly earlier versions but this is not guaranteed) but makes numerous local and behavioral changes that should be reviewed before upgrading production systems.
+
+After this release we're going to be working to get to a more frequent, less extreme, more "agile" release cadence.
+
+Protocol changes:
+
+ * Trusted paths have been completely removed. The new AES mode is so fast on CPUs with AES acceleration that much of the rationale for this is gone, and this feature was never used much to begin with due to inconvenience and obvious security concerns. Environments using trusted paths will need to upgrade all nodes at once.
+ * The symmetric encryption algorithm and mode is now AES-GMAC-SIV, a variation of AES-GCM using the same primitives but offering superior security bounds and behavior under non-ideal conditions. It's also a lot faster than Salsa20/12 and Poly1305 on CPUs with AES acceleration (almost all desktops, laptops, and newer routers and phones). Salsa20/12 with Poly1305 is still supported for communication with older versions and small devices that lack AES acceleration.
+ * A new identity type (1) has been introduced that contains both Curve25519 and NIST P-384 public key types, but classic type 0 remains the default for new identities for now. ECDH key agreement between V1 identities uses both keys and hashes the resulting secrets to yield security equal to the best of the two, but V1 identities can also agree with V0 identities using only their Curve25519 component.
+ * Roots can now be joined and left like networks in a much more convenient way, and the old "moon" and "planet" terminology is deprecated.
+ * A new peer to peer multicast algorithm has been introduced that offers much better scalability and better performance, especially when the physical network itself is hub-and-spoke with many low latency peers connected by higher latency WAN links.
+ * Forward secrecy is finally supported via periodic re-keying using ephemeral asymmetric keys. Both Curve25519 and NIST P-384 keys are used with secrets being hashed to provide security equal to the stronger of the two curves.
+ * As part of forward secrecy implementation peers now always exchange HELLO messages even if they don't have a direct path.
+ * Compression is only enabled for control packets as almost all data packets are largely un-compressable.
+ * New NAT traversal tricks have been added, such as (ab)use of port 500.
+
+Code changes:
+
+ * Migrated from GNU make to cmake for easier cross platform builds and simplified build files.
+ * The core network hypervisor has been significantly refactored, almost amounting to a partial rewrite.
+ * Critical packet handling paths have been streamlined with unnecessary memcpy() steps removed.
+ * Host service code has been completely rewritten in Go. Packet handling code remains in C++, but Go offers superior developer productivity when it comes to implementing more complex local service and local API features. Go imposes a little bit more memory overhead but not much and has been tuned to minimize memory use.
+
+User interface:
+
+ * Command line interface has been redesigned and rewritten. Old commands names are supported but their output will be different.
+
+Other things:
+
+ * The V2 design, protocol, and cryptographic primitives (AES-GMAC-SIV) have been security audited by [Trail of Bits](https://www.trailofbits.com), and the code is being audited as well prior to full 2.0 release.

+ * Update default root list to latest
+ * ARM32 platform build and flag fixes
+ * Add a clarification line to LICENSE.txt
+ * Fix license message in CLI
+ * Windows service now looks for service command line arguments
+ * Fixed a bug that could cause excessive queued multicasts
+
+# 2019-08-23 -- Version 1.4.4
+
+ * Change license from GPL3 to BSL 1.1, see LICENSE.txt
+ * Fix an issue with the "ipauth" rule and auto-generated unforgeable IPv6 addresses
+ * Fix socket/bind errors setting IPs and routes on Linux

+ * Fix high CPU use bug on some platforms
+ * Fix issues with PostgreSQL controller DB (only affects Central)
+ * Restore backward compatibility with MacOS versions prior to 10.13
+
+# 2019-07-29 -- Version 1.4.0
+
+### Major Changes
+
+ * Mac version no longer requires a kernel extension, instead making use of the [feth interfaces](https://apple.stackexchange.com/questions/337715/fake-ethernet-interfaces-feth-if-fake-anyone-ever-seen-this).
+ * Added support for concurrent multipath (multiple paths at once) with traffic weighting by link quality and faster recovery from lost links.
+ * Added under-the-hood support for QoS (not yet exposed) that will eventually be configurable via our rules engine.
+
+### Minor Changes and Bug Fixes
+
+ * Experimental controller DB driver for [LF](https://github.com/zerotier/lf) to store network controller data (LFDB.cpp / LFDB.hpp).
+ * Modified credential push and direct path push timings and algorithms to somewhat reduce "chattiness" of the protocol when idle. More radical background overhead reductions will have to wait for the 2.x line.
+ * Removed our beta/half-baked integration of Central with the Windows UI. We're going to do a whole new UI of some kind in the future at least for Windows and Mac.
+ * Fixed stack overflow issues on Linux versions using musl libc.
+ * Fixed some alignment problems reported on ARM and ARM64, but some reports we could not reproduce so please report any issues with exact chip, OS/distro, and ZeroTier version in use.
+ * Fixed numerous other small issues and bugs such as ARM alignment issues causing crashes on some devices.
+ * Windows now sets the adapter name such that it is consistent in both the Windows UI and command line utilities.
+
+# 2018-07-27 -- Version 1.2.12
+
+ * Fixed a bug that caused exits to take a long time on Mac due to huge numbers of redundant attempts to delete managed routes.
+ * Fixed a socket limit problem on Windows that caused the ZeroTier service to run out of sockets, causing the UI and CLI to be unable to access the API.
+ * Fixed a threading bug in the ZeroTier Core, albeit one that never manifested on the regular ZeroTier One service/client.
+ * Fixed a bug that could cause the service to crash if an authorized local client accessed an invalid URL via the control API. (Not exploitable since you needed admin access anyway.)
+
+# 2018-05-08 -- Version 1.2.10
+
+ * Fix bug loading `moons.d/` files for federated root operation.
+ * Fix compile problem with ZT_DEBUG on some versions of `clang`
+ * Fix slow network startup bug related to loading of `networks.d/` cache files
+
+# 2018-04-27 -- Version 1.2.8
+
+ * Linux version once again builds with PIE (position independent executable) flags
+ * Fixed bug in zerotier-idtool file sign and verify
+ * Fixed minor OSX app typo
+ * Merged alpha NetBSD support (mostly untested, so YMMV)

 You will need [Packages](http://s.sudre.free.fr/Software/Packages/about.html) and our release signing key in the keychain.
 
-## Linux
-
-See `LinuxBuild` environment on `linux-build` VM and use: `chroots/mount-build.sh`, `chroots/build.sh`, and the scripts in `build/` to make APT and RPM repositories.
-
 ## Windows
 
 First load the Visual Studio solution and rebuild the UI and ZeroTier One in both x64 and i386 `Release` mode. Then load [Advanced Installer Enterprise](http://www.advancedinstaller.com/), check that the version is correct, and build. The build will fail if any build artifacts are missing, and Windows must have our product singing key (from DigiCert) available to sign the resulting MSI file. The MSI must then be tested on at least a few different CLEAN Windows VMs to ensure that the installer is valid and properly signed.
-
-*After the MSI is published to download.zerotier.com in the proper RELEASE/#.#.#/dist subfolder for its version* the Chocolatey package must be rebuilt and published. Open a command prompt, change to `ext/installfiles/windows/chocolatey`, and type `choco pack`. Then use `choco push` to push it to Chocolatey (API key required).
-
-    choco pack
-    choco push zerotier-one.#.#.#.nupkg -s https://chocolatey.org/
-
-Note that this does not cover rebuilding the drivers or their containing MSI projects, as this is typically not necessary and they are shipped in binary form in the repository for convenience.

+ZeroTier security and cryptographic design
+=======
+
+(c)2020 ZeroTier, Inc.  
+Author(s): Adam Ierymenko <adam@zerotier.com>
+
+# Introduction
+
+This document describes the core components of ZeroTier's cryptographic and security architecture. It focuses primarily on version 2.0 and only briefly touches on v1.x constructions that are being phased out.
+
+The intended audience for this document is developers, auditors, and security professionals wishing to understand ZeroTier's design from a security posture point of view. It's also written to serve as the basis for professional security audits of the ZeroTier protocol and code base.
+
+## High-Level Protocol Design
+
+ZeroTier's protocol is split into two conceptual layers that we term **VL1** and **VL2**.
+
+VL1 stands for *virtual layer 1* and is a cryptographically addressed secure global peer-to-peer network responsible for moving packets between ZeroTier nodes. It's a virtual analogue of the physical wire or radio transciever in an Ethernet or WiFi network respectively. Think of it as a gigantic wire closet for planet Earth.
+
+VL2 stands for *virtual layer 2* and is a full Ethernet emulation layer incorporating cryptographic certificate and token based access control. It is similar (but not identical) to other Ethernet virtualization protocols like VXLAN. VL2 is conceptually separate from VL1 but for the sake of simplicity and ease of use leverages VL1's cryptographic infrastructure for its own authentication needs.
+
+## VL1 Asymmetric Cryptography: Identities, and Addressing
+
+VL1 peers are cryptographically addressed, meaning addresses are strongly bound to public keys. Cryptographic addressing is extremely convenient in peer-to-peer networks as it leverages authenticated (AEAD) encryption to implicity authenticate endpoint addresses.
+
+A ZeroTier identity is comprised of one or more cryptographic public keys and a short **ZeroTier address** derived from a hash of those keys. In addition to this short address there also exists a longer fingerprint in the form of a SHA-384 hash of identity public key(s).
+
+#### Identity Types and Corresponding Algorithms
+
+* **Type 0** (v1.x and v2.x): one Curve25519 key for elliptic curve Diffie-Hellman and one Ed25519 key for Ed25519 signatures, with the address and fingerprint computed from a hash of both.
+* **Type 1** (v2.x only): Curve25519, Ed25519, and NIST P-384 public keys, with the latter being used for signatures (the Ed25519 key is still there but is presently unused) and with *both* Curve25519 and NIST P-384 being used for elliptic curve Diffie-Hellman key agreement. In key agreement the resulting raw secret keys are hashed together using SHA-384 to combine them and yield a single session key.
+
+Session keys resulting from identity key exchange and agreement are *long-lived keys* that remain static for the lifetime of a particular pair of identities. A different mechanism is used for ephemeral key negotiation.
+
+#### ZeroTier Addresses and Identity Fingerprints
+
+In the simplest form of cryptographic addressing, keys are used directly as addresses throughout the system. Unfortunately even public key cryptosystems with short keys like Curve25519 still result in string representations that are prohibitively long for human beings to type. ZeroTier mitigates this usability problem by using a short hash of the public key termed a **ZeroTier address** to refer to a peer's full identity. This short address is also used at the wire level to reduce the size of the packet header. Peers may request full identities based on addresses from from root servers.
+
+ZeroTier addresses are very short: only 40 bits or 10 hexadecimal digits, e.g. `89e92ceee5.` This makes them convenient to type, but such a short hash would in a naive implementation introduce a significant risk that an attacker could create a duplicate identity with a different key pair but the same address. With 40 bits an intentional collision would require only an average of about 549,755,813,888 attempts for a 50% chance of colliding. If an attempt requires 0.5ms of CPU time on a typical contemporary desktop or server CPU, this would require about 3,000 CPU-days. Since this type of search is easy to parallelize, it would take only a few days for someone with access to a few thousand CPU cores.
+
+To provide this short hash with a larger security margin, an intentionally slow one-way "hashcash" or "proof of work" function is required during identity generation. This work function is slow to compute but fast to verify, and an address is not valid unless its work checks out. This gives identity address derivation the following costs:
+
+* Type 1 identities: an average of about 500ms per key pair per typical 2.4ghz CPU core, requiring around 3 million CPU-days to reach a 50% collision probability.
+* Type 2 identities: an average of about one second per key pair per typical 2.4ghz CPU core, requiring around 6.3 million CPU-days to reach a 50% collision probability.
+
+While too costly for the vast majority of attackers, this cost may not be prohibitive to a nation-state level attacker or to a criminal with significant funds and/or access to a very large "botnet." It's also possible that FPGA, GPU, or ASIC acceleration could be leveraged to decrease this time in a manner similar to what's been accomplished in the area of cryptocurrency mining.
+
+Fingerprints are full SHA-384 hashes of identity public keys. In base32-encoding they look like this:
+
+```
+bzg7fc3sn46fzyxcxw2ev4c4m2u5fyisb3o4wz5hfmvexbzwk6et3fsglkdcn6nnjobxi3bq7hgxqox3n4u4k
+```
+
+These are too large to type but not to copy/paste, store in databases, or use in scripts and APIs.
+
+Once a device has joined a network, network controllers will remember and check its full identity or identity fingerprint (depending on implementation) rather than just the device's ZeroTier address.
+
+## VL1 Wire Protocol
+
+ZeroTier's wire protocol is packet based with packets having the following format:
+
+```
+[0:8]    64-bit packet ID and cryptographic nonce
+[8:13]   40-bit destination ZeroTier address
+[13:18]  40-bit source ZeroTier address
+[18:19]  8-bit cleartext flags, cipher, and hop count (bits: FFCCCHHH)
+[19:27]  64-bit message authentication code (MAC)
+-- BEGIN ENCRYPTED SECTION --
+[27:28]  8-bit inner flags and 5-bit protocol verb (bits: FFFVVVVV)
+[28:...] Verb-specific packet payload
+```
+
+All fields (both those that remain cleartext and those that are encrypted) in a packet are authenticated except for the last three "hops" bits of the combined flags/cipher/hops field. These are masked to zero during MAC computation and verification. This is because the hops field is the only field that can be modified by third party peers in transit. It's incremented whenever a packet is forwarded by a root server or connectivity-assisting peer and is checked against a limit to prevent infinite forwarding loops.
+
+Packets can be up to 16,384 bytes in size. Since the most common transport is UDP and this transport does not reliably support fragmentation, ZeroTier implements its own packet fragmentation and re-assembly scheme using fragments with the following wire format:
+
+```
+[0:8]    64-bit packet ID of packet of which this is a fragment
+[8:13]   40-bit destination ZeroTier address
+[13:14]  0xff here indicates a fragment since addresses cannot start with this byte
+[14:15]  4-bit total fragments and 4-bit fragment number (bits: TTTTNNNN)
+[15:16]  5 reserved bits, 3-bit hop count (bits: rrrrrHHH)
+[16:...] Fragment data
+```
+
+A fragmented packet is indicated by the presence of the flag 0x40 in its cleartext flags field. If this flag is present the receiver must expect the receipt of one or more fragments in addition to the packet's header and first fragment. The total number of fragments expected is not contained in the header but will be contained within each subsequent fragment. If a fragment is received prior to its head, it's held in the event that its head arrives as the protocol does support out of order receipt of fragments.
+
+Fragmentation can be effectively ignored from a security point of view (with the exception of denial of service concerns, which are mitigated by way of limits and heuristics in the code) since packet message authentication codes are checked at the packet level. Any improperly fragmented packet will fail cryptographic MAC check and be discarded.
+
+*Legacy: In v1.x the packet ID and nonce field was assigned from a counter maintained to avoid duplicate nonce assignment and the MAC field was the first 64 bits of a Poly1305 MAC of the packet. The overall construction was identical in form to the NaCl Salsa20/Poly1305 "secret box" construction in which the first 32 bytes of Salsa20 output are used as a one-time Poly1305 key for each packet.*
+
+In v2.x the packet ID and MAC field are in reality a single split 128-bit encrypted nonce and MAC field. See AES-GMAC-SIV below.
+
+## Symmetric Encryption: AES-GMAC-SIV
+
+**This is a draft and may change based on peer review and feedback.**
+
+In v1.x there is a risk of nonce re-use due in part to the small size of the MAC and in part to the way ZeroTier is used. More specifically the risk arises when ZeroTier VMs are cloned or ZeroTier is used on small devices that have the potential to lack both accurate timekeeping and native strong random sources.
+
+Salsa20 was used in v1.x since at the time the protocol was initially designed AES acceleration was not available on most mobile phones, embedded chips, and small ARM processors such as those use on Raspberry Pi and similar devices. This is no longer the case.
+
+For v2.x our design has three objectives:
+
+- Make use of FIPS140-compliant cryptographic primitives that would be available in a FIPS140-ceritified library (e.g. a FIPS build of crypto++ or openssl libcrypto), and use them in a way that could pass FIPS/NIST/NSA review.
+- Use AES with hardware acceleration for extremely high performance processors with AES hardware acceleration, which is most non-trivial CPUs today.
+- Incorporate some form of nonce-reuse-resistance to reduce the risk of duplicate nonces when virtual machines are cloned or on small devices, and to mitigate the short MAC.
+
+The proposed AES-GMAC-SIV construction attempts to achieve all these objectives by using GMAC combined with AES-CTR (both FIPS140 primitives) in a way that achieves the security bounds and characteristics of AES-GCM-SIV but could be certified as FIPS compliant. The design is almost identical to another proposed mode called AES-GCM-SIV except that GMAC is used "as-is" for FIPS-certifiability reasons.
+
+#### AES-GMAC-SIV Session Setup
+
+For each new session key, derive two sub-keys **K0** and **K1** using a key derivation function such as KBKDF-HMAC-SHA384.
+
+#### AES-GMAC-SIV Encryption
+
+<img src="AES-GMAC-SIV.png">
+
+As with all other SIV (synthetic IV) modes of operation, encryption requires two passes. Since messages are small in our system it's very likely that the second pass would be operating on data already in CPU L0 cache, reducing the additional overhead of this two-pass requirement.
+
+1. Generate a new unique 64-bit packet ID in the same manner as v1.x.
+2. Expand this 64-bit ID to a 96-bit AES-GMAC nonce by padding the remainder with the size of the packet in bytes and the direction of communication (sender > recipient or recipient > sender). This adds a small amount of additional entropy taken from characteristics of the packet.
+3. Using session sub-key **K0** compute AES-GMAC(K0, plaintext) to yield a 128-bit GMAC tag.
+4. Take the first 64 bits of this 128-bit GMAC tag and append it to the 64-bit packet ID generated in step 1 to yield a 128-bit combined nonce+MAC field.
+5. Obtain a 128-bit AES-CTR nonce by encrypting this 128-bit combined nonce+MAC field as a single AES block using **K1**. This is done because GMAC alone is not a cryptographic PRF (pseudo-random function) and we want to ensure that we destroy any algebraic structure before using it with AES-CTR.
+6. Using the encrypted nonce+MAC field as a 128-bit nonce, encrypt the encrypted section of the packet with AES-CTR. This is also done using **K1**, meaning that the first block of CTR padding data is actually AES(K1,AES(K1,nonce+MAC)).
+7. Encrypt the 128-bit AES-CTR nonce again as a single AES block using **K0** to yield a final encrypted 128-bit combined nonce and MAC. *(Question for peer review: does this step have any attack-mitigating value? AES-CTR does not require that its nonce/IV be a secret.)*
+8. Split this final encrypted nonce+IV into two 64-bit chunks, replacing the packet ID with one and placing the other in the packet MAC field.
+
+#### AES-GMAC-SIV Decryption
+
+Unlike encryption, SIV decryption can be performed in a single pass if there is a performance benefit to doing so.
+
+1. Re-combine the packet ID and MAC fields into a single 128-bit block.
+2. Decrypt this block with AES using **K0** to yield the AES-CTR nonce.
+3. Decrypt the packet using AES-CTR with **K1**.
+4. Decrypt the 128-bit AES-CTR nonce field *again* as a single AES block using **K1** to obtain the original packet nonce and 64-bit truncated GMAC tag.
+5. Expand the 64-bit packet ID / nonce into a 96-bit GMAC nonce as in encryption step 2.
+6. Compute AES-GMAC(K0,plaintext) as in encryption step 3.
+7. Verify that the first 64 bytes of the resulting GMAC tag equals the tag (last 64 bits) obtained in decryption step 4 and discard the packet if they do not match.
+
+#### Discussion
+
+Most standard stream cipher modes such as AES-GCM or Salsa20/Poly1305 require that message nonce/IV values are never duplicated for the same session key. Since these stream modes generate key streams that are simply XORed with message plaintext, nonce duplication reveals the plaintext of both messages for which the nonce is duplicated due to the commutativity of the XOR operation. It may also allow the MAC (GMAC or Poly1305) itself to be attacked in such a way as to enable message forgery.
+
+SIV modes mitigate these attacks by making the actual cryptographic nonce used for stream encryption dependent on the content of the message. If a nonce is repeated when two messages differ, ciphertext will still be unique unless a MAC collision also occurs. The chance of this is quite small, only 1/2^64 in our system for any given pair of repeated nonce values. If a repeated nonce occurs and both messages are the same, the protocol will leak only the fact that a message was repeated. The actual plaintext and MAC are not compromised.
+
+Our AES-GMAC-SIV mode is almost identical to a proposed mode called [AES-GCM-SIV](https://cyber.biu.ac.il/aes-gcm-siv/). The proposed AES-GCM-SIV mode uses a variant of GMAC called POLYVAL with very minor performance improvements while ours retains standard GMAC for compatibility with existing standards and libraries. We call our mode AES-GMAC-SIV to distinguish it.
+
+*Question for peer review: both GMAC and AES-CTR are FIPS140 approved primitives, and the use of AES-CTR with an approved MAC is permitted. Is it actually feasible that this could be FIPS certified if it were documented in a correct and "strategic" way? It would be described as GMAC authenticated AES-CTR with the CTR IV being constructed via keyed hash (AES) from an initial plaintext IV and a "salt" taken from the MAC, or some similar description.*
