-                       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,

-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.

+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.

  - `java/`: a JNI wrapper used with our Android mobile app. (The whole Android app is not open source but may be made so in the future.)
  - `macui/`: a Macintosh menu-bar app for controlling ZeroTier One, written in Objective C.
  - `node/`: the ZeroTier virtual Ethernet switch core, which is designed to be entirely separate from the rest of the code and able to be built as a stand-alone OS-independent library. Note to developers: do not use C++11 features in here, since we want this to build on old embedded platforms that lack C++11 support. C++11 can be used elsewhere.
  - `osdep/`: code to support and integrate with OSes, including platform-specific stuff only built for certain targets.
+ - `rule-compiler/`: JavaScript rules language compiler for defining network-level rules.
  - `service/`: the ZeroTier One service, which wraps the ZeroTier core and provides VPN-like connectivity to virtual networks for desktops, laptops, servers, VMs, and containers.

 ### 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`).
+   - GNU make is required. Type `gmake` to build.
 
 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.

         * The Windows installer should now install the driver without requiring a special prompt in most cases. This should make it easier for our packages to be accepted into and updated in the Chocolatey repository and should make it easier to perform remote installs across groups of machines using IT management and provisioning tools.
         * The Windows official packages are now signed with an EV certificate (with hardware key).

 ## Major Bug Fixes in 1.2.0
 
  * **The Windows HyperV 100% CPU bug is FINALLY DEAD**: This long-running problem turns out to have been an issue with Windows itself, but one we were triggering by placing invalid data into the Windows registry. Microsoft is aware of the issue but we've also fixed the triggering problem on our side. ZeroTier should now co-exist quite well with HyperV and should now be able to be bridged with a HyperV virtual switch.
- * **Segmenation faults on musl-libc based Linux systems**: Alpine Linux and some embedded Linux systems that use musl libc (a minimal libc) experienced segmentation faults. These were due to a smaller default stack size. A work-around that sets the stack size for new threads has been added.

  * **Windows firewall blocks local JSON API**: On some Windows systems the firewall likes to block 127.0.0.1:9993 for mysterious reasons. This is now fixed in the installer via the addition of another firewall exemption rule.
  * **UI crash on embedded Windows due to missing fonts**: The MSI installer now ships fonts and will install them if they are not present, so this should be fixed.
