Default Bug#668511: Kernel panic with bridge networking

Package: linux-image-3.2.0-2-amd64*

Version: 3.2.12-1

Severity: important



Hello,



i am experiencing a panic whose logs are attached (grabbed with
netconsole).



They look quite similar to what has been described here

** http://www.spinics.net/lists/linux-net/msg17689.html



The patch proposed as the solution (commit
6b1e960fdbd75dcd9bcc3ba5ff8898ff1ad30b6e) seems to be applied (even
with small differences) but the problem persists.



-------------

if (pf == PF_INET && br_parse_ip_options(skb))

*************** return NF_DROP;

-------------



The kernel is a debian linux-image-3.2.0-2-amd64 which should be a
plain 3.2.12



I have checked the changelog of 3.2.13 and 3.2.14 and it doesn't
seems to be any commit regarding such problem.

Any hint ?

Hope that helps,

Subject: set fake_rtable's dst to NULL to avoid kernel Oops.

When bridge is deleted before tap/vif device's delete, kernel may encounter an oops because of NULL reference to fake_rtable's dst.
Set fake_rtable's dst to NULL before sending packets out can solve this problem.

Hi Jonathan,

It didn't work the way it was described in that document. Probably
because i'm on squeeze and test-patch throw some python exceptions that
do not happen on wheezy.


Instead:
- i downloaded the debian sourrces with dget.
- i applied the patch manually (it's very short) because the offsets
were not the same

- i re-generated the sources with dpkg-buildpackage -S
- i boult the whole linux-$stuff with pbuilder.

I have installed that kernel on a test server and it seems to work.

Max

Hi Jonathan,

please notice that they submitted another patch here:

http://thread.gmane.org/gmane.linux.kernel/1283857

It's basically the previous one, with the same solution but with
additional "embellishments".


The patch i applied yesterday to the debian kernel has been installed
and the kernel is not panic-ing anymore.


I'll try to keep this bug up to date.

Thanks,
Max

Yep, they seem to be dealing now with small details like the
changelog and comments, which is a good sign.

Thanks again for testing. I've passed this information upstream.

Sounds painful. Here are instructions for testing against upstream
source, which might be easier.

0. prerequisites

apt-get install git build-essential

1. get the kernel history, if you don't already have it

git clone
git://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git

2. fetch point releases

cd linux
git remote add stable
git://git.kernel.org/pub/scm/linux/kernel/git/stable/linux-stable.git
git fetch stable

3. configure, build, test

git checkout stable/linux-3.2.y
cp /boot/config-$(uname -r) .config; # current configuration
scripts/config --disable DEBUG_INFO
make localmodconfig; # optional: minimize configuration
make deb-pkg; # optionally with -j<num> for parallel build
dpkg -i ../<name of package>
reboot

Hopefully it reproduces the bug. So:

4. try the patch

cd linux
git cherry-pick -x -s a881e963c7fe
make deb-pkg; # maybe with -j4
dpkg -i ../<name of package>
reboot

You wrote at [1] that this doesn't seem to have completely solved the
bridging-related panics. Am I correct in assuming the patch still
works as advertised, though? Are there other patches we should pick
up?

Hope that helps,
Jonathan

Hi Jonathan,

For the bridge related panics, i have sent another couple of panics here:

- http://marc.info/?t=133699959300002&r=1&w=2

But i have no reply, yet and the problem is still open (no one cares ?).
The panic is reproduceable very easily.

I'll let you know as soon as i have the new kernel running and compiled
as you explained.


Thank you very much.

Max

Sounds painful. Here are instructions for testing against upstream
source, which might be easier.

Hi,

I'm sorry for this late reply but i had a lot of problems and i lost
time reverting the kernel to a 2.6 series one to avoid panics.


Today i have installed the latest debian kernel from the testing
repository (linux-image-3.2.0-2-amd64 - 3.2.20-1) and the panics are
still present.

I'm attaching 2 of them grabbed through netconsole.

Then i compiled, using your instructions, the latest 3.2.21 and i had
(after 5 minutes of uptime) another panic which seems different.

The panic with a 3.2.21 is attached as well.

I don't really know the cause (i'm not a kernel hacker) but it seems
related to bridges and to "aliased" bridge interfaces.
I'm using heartbeat for high availability and if the aliased bridged IPs
are moved to the other node, the panic does not happen.


Max

P.S.: (i'll send another email to netdev@vger)

Default Bug#668511: Kernel panic with bridge networking
