Wireshark · Wireshark-dev: Re: [Wireshark-dev] Adding a new dissector - beginners guide

[Michal Orynicz <michal.orynicz@xxxxxxxxx>]

Hi,

the best line of doing this would be going to https://code.wireshark.org/review/, registering there and then pushing Your change to https://code.wireshark.org/review/wireshark . This way the changes will go through review in gerrit, and no matter how bad or how good Your code is, it will stay there until it is decided to be ready and safe to be incorporated to the main branch :)

Hi,
I have written a dissector for a protocol which I call "S7 communication".
I've hosted it as plugin dll at sourceforge, but I think the better way
is to contribute it direct into wireshark (if it's good enough).

I've changed the dissector from plugin to internal and did the
testtools, so I think I am ready to go.

The main problem is that I'm new to git/gerrit. I don't want to destroy
or confuse anything in your code repository, and the wireshark docs
don't write it step by step how to do it. I would like to write down
what I want to do, and I hope that someone corrects me when I am wrong.

What I have done:
- created a local copy via git clone
https://code.wireshark.org/review/wireshark
- I've added four files into epan/dissectors:
packet-s7comm.c
packet-s7comm_szl_ids.c
packet-s7comm.h
packet-s7comm_szl_ids.h
- I've changed two files:
epan/CMakeLists.txt
epan/dissectors/Makefile.common
config.nmake

And the steps to push the files up (haven't done it yet):

git add epan/dissectors/packet-s7comm.c
git add epan/dissectors/packet-s7comm_szl_ids.c
git add epan/dissectors/packet-s7comm.h
git add epan/dissectors/packet-s7comm_szl_ids.h
git add epan/CMakeLists.txt
git add epan/dissectors/Makefile.common
git commit -m "Add S7COMM protocol" -m "Dissector T.125 has to be
disabled to let this dissector work."

and finally:

git push ssh://thomas_v2@xxxxxxxxxxxxxxxxxx:29418/wireshark
HEAD:refs/for/master/s7comm


I don't know how to fix the problem with the concurrent T.125 dissector,
seems that my captures are also valid T.125 protocols.

Thanks,

Thomas Wiens
