[Bug 669500] Re: TIPC 2.0 API/ABI breaking changes


luca, this bug was reported a while ago and there hasn't been any
activity in it recently. We were wondering if this is still an issue? If
so, could you please test for this with the latest development release
of Ubuntu? ISO images are available from http://cdimage.ubuntu.com
/daily-live/current/ .

If it remains an issue, could you please run the following command in
the development release from a Terminal
(Applications->Accessories->Terminal), as it will automatically gather
and attach updated debug information to this report:

apport-collect -p linux <replace-with-bug-number>

Also, could you please test the latest upstream kernel available (not the daily folder) following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested. If this bug is fixed in the mainline kernel, please add the following tags:

where VERSION-NUMBER is the version number of the kernel you tested. For example:

This can be done by clicking on the yellow circle with a black pencil icon next to the word Tags located at the bottom of the bug description. As well, please remove the tag:

If the mainline kernel does not fix this bug, please add the following tags:

As well, please remove the tag:

Once testing of the upstream kernel is complete, please mark this bug's
Status as Confirmed. Please let us know your results. Thank you for your

  TIPC 2.0 API/ABI breaking changes

Status in “linux” package in Ubuntu:

Bug description:
  TIPC 2.0 (included in kernel 2.6.35) has a serious regression that
  breaks API and ABI compatibility with previous versions. Programs that
  used to compile and work previous versions, don't work with 2.6.35,
  even if you recompiled them with the 2.6.35 tipc.h header.

  For the full discussion please see this thread:

  See: http://www.spinics.net/lists/netdev/msg144489.html

  The problem is, they are not  yet in stable released kernels, so it
  could be nice if Ubuntu patches the distributed kernel to behave
  correctly with TIPC applications.

  Note that package linux-libc-dev should be updated too to include the
  patched /usr/include/linux/tipc.h.
