William Lallemand 2be58f7584 MINOR: contrib: make the peers wireshark dissector a plugin
The wireshark dissector could only be build within wireshark, which
means maintaining a wireshark binary just for this dissector. It was not
really convenient to update wireshark because of this.

This patch converts the dissector into a .so plugin which is built with
the .h found in distributions instead of the whole wireshark sources.

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".
