Fix TEST simplification logic (again).

"ip.DstAddr >= 0.0.0.0" ---> "ip"
"ip.DstAddr <  0.0.0.0" ---> "false"

Previously, the latter simplified to "not ip".

CHANGELOG

@@ -84,3 +84,237 @@ WinDivert 1.3.0
       callout drivers.
     - WinDivertSend() has been optimized.  However, it may not detect as
       many packet injection errors as it could before.
+WinDivert 1.4.0-rc
+    - Add a new WINDIVERT_PARAM_QUEUE_SIZE parameter that can be used to
+      control the maximum number of bytes used by the packet queue.
+    - Add a new WINDIVERT_FLAG_DEBUG flag that causes WinDivertSend() to
+      block until the packet exits the Windows TCP/IP stack.  This is slower
+      but provides better error messages, so is useful for debugging.
+    - Internally queued packets are now reinjected when WinDivertClose() is
+      called instead of being dropped.
+    - WINDIVERT_ADDRESS now includes a Timestamp field that indicates when
+      the packet was first captured by WinDivert.  The timestamp uses the
+      same clock as QueryPerformanceCounter().
+    - WINDIVERT_ADDRESS now includes a Loopback field that indicates whether
+      the packet is a loopback packet or not.
+    - The filter language has been extended to include a loopback field that
+      matches loopback packets.
+    - Loopback packets are now considered to be outbound-only.
+    - WINDIVERT_ADDRESS now includes an Impostor field which indicates that the
+      packet originated from another driver rather than from the network or
+      TCP/IP stack.
+    - WinDivertRecv() will eventually fail with ERROR_HOST_UNREACHABLE if
+      an impostor packet enters an infinite loop (see #41).
+    - The filter language has been extended to include an impostor field that 
+      matches impostor packets.
+    - WINDIVERT_ADDRESS now includes three new flags relating to checksums:
+      * PseudoIPChecksum
+      * PseudoTCPChecksum
+      * PseudoUDPChecksum
+      When set, these flags indicate that the corresponding packet uses
+      "pseudo" IP/TCP/UDP checksums instead of the default full checksums.
+      Pseudo checksums are cheaper to calculate, and can be used when the
+      network hardware supports checksum offloading.
+    - WinDivertHelperCalcChecksums() now takes an optional pointer to a
+      WINDIVERT_ADDRESS structure, and calculates pseudo checksums if the
+      corresponding Pseudo*Checksum flag is set.
+    - The WINDIVERT_HELPER_NO_REPLACE flag for WinDivertHelperCalcChecksums()
+      has been deprecated.  It is no longer necessary to calculate checksums
+      for unmodified packets.
+WinDivert 1.4.1
+    - Dual license WinDivert under LGPLv3 and GPLv2.
+WinDivert 1.4.2
+    - Add workaround for pseudo checksum issue (see #134).
+WinDivert 1.4.3
+    - WinDivert.dll no longer depends on MSVCRT*.dll.
+WinDivert 2.0.0-rc
+    - Add 3 new layers:
+      * WINDIVERT_LAYER_FLOW for tracking network "flow" events.
+      * WINDIVERT_LAYER_SOCKET for tracking "socket" events.
+      * WINDIVERT_LAYER_REFLECT for tracking WinDivert events.
+    - WINDIVERT_ADDRESS has been re-factored as follows:
+      * addr.Layer: The WINDIVERT_LAYER_* value for the handle.
+      * addr.Event: A WINDIVERT_EVENT_* value representing the event (see
+        below).
+      * addr.Sniffed: Indicates that the event was sniffed.
+      * addr.Outbound: Replaces addr.Direction.
+      * addr.IPv6: Indicates an IPv6 packet.

+      * addr.Socket.LocalPort: The socket's local port.
+      * addr.Socket.RemotePort: The socket's remote port.
+      * addr.Socket.Protocol: The socket's protocol.
+      * addr.Reflect.ProcessId: The ID of process that created opened the
+        handle.
+      * addr.Reflect.Timestamp: The timestamp of the handle.
+      * addr.Reflect.Layer: The layer of the handle.
+      * addr.Reflect.Flags: The flags of the handle.
+      * addr.Reflect.Priority: The priority of the handle.
+    - The addr.Event field can take the following values:

+        operation occurred.
+      * WINDIVERT_EVENT_REFLECT_CLOSE: (REFLECT layer) a WinDivertClose()

+      * endpointId: (FLOW/SOCKET layers) the endpoint ID.
+      * parentEndpointId: (FLOW/SOCKET layers) the parent endpoint ID.

+      Furthermore, the index can be:
+      * Positive, representing addressing from the start of the
+        packet/payload.
+      * Negative, representing addressing from the end of the packet/payload.
+    - The WinDivert filter language now supports several symbolic values:
+      * PACKET: (NETWORK/NETWORK_FORWARD layers) equal to
+        WINDIVERT_EVENT_NETWORK_PACKET
+      * ESTABLISHED: (FLOW layer) equal to WINDIVERT_EVENT_FLOW_ESTABLISHED.

+      * ICMP: equal to IPPROTO_ICMP (1).
+      * ICMPV6: equal to IPPROTO_ICMPV6 (58).
+    - WinDivertOpen() now supports several new flags:
+      * WINDIVERT_FLAG_RECV_ONLY/WINDIVERT_FLAG_READ_ONLY: The handle cannot
+        be used for send operations.
+      * WINDIVERT_FLAG_SEND_ONLY/WINDIVERT_FLAG_WRITE_ONLY: The handle cannot
+        be used for receive operations.
+      * WINDIVERT_FLAG_NO_INSTALL: If the WinDivert driver is not already
+        installed/loaded, then WinDivertOpen() will fail with an error.
+    - WinDivertRecvEx()/WinDivertSendEx() now support a "batch" mode that
+      allows more than one packet to be received/sent at once.  The number
+      of packets is determined by a new pAddrLen/addrLen parameter.
+    - Add a new WinDivertShutdown() function that supports the following
+      modes:
+      * WINDIVERT_SHUTDOWN_RECV: Disable the queuing new packets.
+      * WINDIVERT_SHUTDOWN_SEND: Disable the sending of new packets.
+      * WINDIVERT_SHUTDOWN_BOTH: Equivalent to
+        (WINDIVERT_SHUTDOWN_RECV | WINDIVERT_SHUTDOWN_SEND).

+    - Add new WinDivertHelperFormatIPv4Address() and
+      WinDivertHelperFormatIPv6Address() helper functions that format
+      IPv4 and IPv6 addresses respectively.
+    - Replace WinDivertHelperCheckFilter() with a new
+      WinDivertHelperCompileFilter() helper function.  The latter can also be
+      used to compile a human-readable filter string into a more compact
+      "object" format.  The object format can be used in place of the
+      human readable format for all WinDivert operations.
+    - Add a new WinDivertHelperFormatFilter() helper function that formats a
+      filter string into a normalized form.  It also can be used to
+      "de-compile" the object format into a human readable form.
+    - Add a new WinDivertHelperDecrementTTL() function that decrements the
+      ip.TTL/ipv6.HopLimit field of a packet.
+    - Add new WinDivertHelperNto*()/WinDivertHelperHton*() helper functions
+      for swapping from network to host byte ordering, and vice versa.
+    - WinDivertOpen() priorities now are ascending, meaning that higher
+      values correspond to higher priorities.
+    - The last two arguments for WinDivertRecv() and WinDivertSend() have been
+      swapped.
+WinDivert 2.0.1-rc
+    - Fix WFP callout install optimization bug.
+    - Fix WinDivertHelperNtohIpv6Address/WinDivertHelperHtonIpv6Address bug.
+    - Rename the following functions for consistency:
+      * WinDivertHelperNtohIpv6Address -> WinDivertHelperNtohIPv6Address
+      * WinDivertHelperHtonIpv6Address -> WinDivertHelperHtonIPv6Address
+WinDivert 2.1.0
+    - WinDivertOpen() now supports a new flag:
+      * WINDIVERT_FLAG_FRAGMENTS: If set, the handle will capture inbound IP
+        fragments, but not inbound reassembled IP packets.  Otherwise, if not
+        set (the default), the handle will capture inbound reassembled IP
+        packets, but not inbound IP fragments.  This flag only affects
+        inbound packets at the NETWORK layer.
+    - Filter fields inbound/outbound are now supported at the SOCKET layer.
+    - Fix BSOD caused by packets with missing or incomplete transport
+      headers (introduced in 2.0.0).
+    - Fix missing Flow.EndpointId and Flow.ParentEndpointId for IPv6 flows.
+WinDivert 2.2.0
+    - Implement new packet parser that correctly handles IP fragments.
+    - Add a new "fragment" filter field that matches IP fragments.
+    - (Un)Loading the WinDivert driver will cause a system event to be logged.
+WinDivert 2.2.1
+    - Fix potential driver deadlock on user-mode program crash.
+    - Fix filter language simplification bug.
+    - Fix Flow.EndpointId containing junk data.
+WinDivert 2.2.2
+    - Fix potential WinDivertClose() BSOD for WINDIVERT_LAYER_FLOW handles.

+
+            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 <https://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
+<https://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

+
+ 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.

-2. Similar Packages
--------------------
-
-WinDivert is similar to divert sockets in FreeBSD/MacOS, NETLINK sockets in
-Linux, and some commercial packet capturing packages such as WinPkFilter for
-Windows.  The design of WinDivert is largely influenced by FreeBSD's divert
-sockets.
-
-WinDivert in packet-sniffing mode is similar to Winpcap.  Unlike Winpcap,
-WinDivert fully supports capturing loopback traffic.   Furthermore, WinDivert
-supports packet interception, which is not supported in Winpcap.
