UPDATE: The last pending patch got merged end of march. You can now use upstream wireshark \o/

Wireshark is a network analyzer. Over the past year, we introduced a number of improvements in MPTCP related dissection:

  1. Registers an ‘mptcp’ protocol
  2. Introduced interval trees to handle DSN/SSN search

To get a full list of loosely related changes, you can run in your wireshark repository:

$ git log --author="Matthieu Coudron" 

There is a last patch pending that needs more work & tests before upstreaming.

For ease of use, we provide a custom github mirror incorporating all current changes (checkout the branch ‘mptcp_final’).

Here is a picture of some additionnal fields that are available when using our version of wireshark: wireshark

The building is the same as for vanilla wireshark. Here is an example on how to install/use it with cmake (wireshark can use autotools directly or cmake):

$ git clone https://github.com/lip6-mptcp/wireshark-mptcp.git
$ cd wireshark-mptcp
$ mkdir debug
$ cd debug

Here is my custom command, feel free to change the compiler to yours or just remove the commands:

$ CXXFLAGS="-Wno-unused-but-set-variable" cmake \
        -G"Unix Makefiles" \
        -DENABLE_GTK3=0 \
        -DENABLE_QT5=1 \
        -DENABLE_GEOIP=0 \
        -DENABLE_SBC=0 \
        -DENABLE_SMI=0 \
        -DENABLE_GNUTLS=1 \
        -DENABLE_GCRYPT=1 \
        -DCMAKE_BUILD_TYPE=Debug \
        -DDISABLE_WERROR=1 \
        .. \
        -DCMAKE_C_FLAGS=$(printf %q "$CFLAGS") \
        -DCMAKE_CXX_FLAGS=$(printf %q "$CXXFLAGS") \
        -DCMAKE_C_COMPILER=clang \

$ make wireshark

Full MPTCP dissection can be quite CPU-consuming (optimization was not our priority), thus we provide some options to enable only the needed features in the menu “Edit -> Preferences -> Protocols -> MPTCP”. Just tick the boxes but keep in mind it is a work in progress and don’t hesitate to report (or fix) bugs in the github tracker.

Here is my custom MPTCP profile in case it helps (finding the field names) !
