1: There is no need to "diagnose the problem".  It has been diagnosed,
solved, and corrected by me, in my role as code maintainer. This is what
I did with the above-mentioned commit; it just didn't make it into 4.4.

2: "apport-collect" seems to assume access to a browser, which I don't
have on my non-graphical server version. Anyway, I don't quite see the
use of it in this case.

3) Apart from the above-mentioned commit, even the following one must be
applied to have a fully robust code:

tipc: allow non-linear first fragment buffer

Please advise me how to proceed.

Title:
  tipc: missing linearization of sk_buff

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  The TIPC binding table sometimes fails to update correctly between
  nodes because we don't linearize nonlinear buffers at two places where
  it is needed in the code.

  In the upstream kernel at kernel.org, the following commit was applied
  on Nov 19th 2015:

  commit c7cad0d6f70cd4ce8644ffe528a4df1cdc2e77f5   ("tipc: move
  linearization of buffers to generic code") that fixes this issue.

  This crucial fix made it into kernel 4.5, but unfortunately not into
  4.4 that is used in Xenial, and makes TIPC in Xenial almost unusable
  as it is now.

  Now I am uncertain about how to proceed with this, since I am new with dealing with the Ubuntu kernel. 
  -  Do you apply such fixes from kernel.org if I post a new one to kernel.org/stable? (The one referred to above won't apply cleanly to 4.4).  
  - Or should I issue a new one directly to Ubuntu's kernel team ? 
  - Or do you fix it yourself (it it pretty trivial and safe if you take a look at the original commit I refer to) ?
