How to build wireshark with HAProxy Peers Protocol dissection support.
------------------------------------------------------------------------

Please note that at this time, HAProxy Peers Protocol dissection is not supported
on Windows systems (could not be tested).

1) File list
-------------
 - packet-happp.c: source code for HAProxy Peers Protocol (HAPPP) dissection
   support.
 - wireshark.happp.dissector.patch: a patch file for wireshark sources to enable HAPPP
   dissection support. Note that this patch file modifies only two files:
   (epan/dissectors/CMakeLists.txt and epan/dissectors/Makefile.am) to add
   packet-happp.c file DISSECTOR_SRC variable which list all wireshark
 - README: this file.

2a) To build wireshark with HAPPP dissection support
---------------------------------------------------
 - Download wireshark sources:
   $ git clone https://code.wireshark.org/review/wireshark
 - copy packet-happp.c file to epan/dissectors/ directory.
 - apply wireshark.happp.dissector.patch file to wireshark source directory.
 - build wireshark (see https://www.wireshark.org/docs/wsdg_html_chunked/):
   $ ./autogen.sh
   $ ./configure
   $ make

2b) Alternative: build the HAPPP dissector as a wireshark plugin
-----------------------------------------------------------------
If you don't want to build completely wireshark, you can build the dissector as
a plugin.

You will need the development package of your distribution, which is
"libwireshark-dev" for debian based distribution and "wireshark-dev" for
redhat-based ones.

$ make

To install it in your home directory:

$ make install

The plugin will be installed in ~/.wireshark/plugins/ by default, but you can
change this path by setting the "plugins" variable. If it didn't work, check
the paths in "Help > About Wireshark > Folders > Personal Plugins" which should
give you the right path to use.

In some distribution it will be in ~/.local/lib/wireshark/ so you will need to
install it this way:

$ make install plugins=~/.local/lib/wireshark/plugins/3.2/epan/

If you want to install it in the system directory you can do it this way, the
righ path is also in the Folder window. Change the plugins variable this way:

$ sudo make install plugins=/usr/lib64/wireshark/plugins/3.2/epan/

Be careful to use the right version number in the path.

3) Check if you have the dissector in wireshark
-----------------------------------------------
To verify if the protocol was well loaded by your wireshark, open the Supported
Protocols window in "View > Internals > Supported Protocols" and look for
"HAPPP".

In the case of a plugin, you should see your plugin loaded in "Help > About
Wireshark > Plugins".
