TIPC 2.0 API/ABI breaking changes

[luca]

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:

http://thread.gmane.org/gmane.network.tipc.general/2259

As a result of this problem, 2 commits have been reverted:

http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=db5a753bf198ef7a50e17d2ff358adf37efe8648
http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=8c974438085d2c81b006daeaab8801eedbd19758

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.

Also, it would be nice if you can remove all the *irrelevant* information collected from my computer (**I CAN'T**). It's *really* **REALLY** annoying not having an option to NOT send that kind of informations. There are cases (like this one) when all that information is completely useless for the bug report and affects my privacy.

Thank you.

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:
kernel-fixed-upstream
kernel-fixed-upstream-VERSION-NUMBER

where VERSION-NUMBER is the version number of the kernel you tested. For example:
kernel-fixed-upstream-v3.13-rc5

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:
needs-upstream-testing

If the mainline kernel does not fix this bug, please add the following tags:
kernel-bug-exists-upstream
kernel-bug-exists-upstream-VERSION-NUMBER

As well, please remove the tag:
needs-upstream-testing

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 understanding.

I'm not using TIPC so is hard to test, but this has been fixed upstream ages ago, so I think it should be safe to assume upstream changes made it into ubuntu, so feel free to close this bug...
