[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-06-20 Thread Heikki Hannikainen
I deployed the actual -proposed kernel 4.4.0-152.179 on 4 servers, and
it is stable for us. Previously there were multiple crashes per day.
Confirming, verification done. Thank you!

  [SRU Justification]

  == Impact ==

  Since 05c0b86b96 "ipv6: frags: rewrite ip6_expire_frag_queue()" the
  16.04/4.4 kernel crashes whenever that functions gets called (on busy
  systems this can be every 3-4 hours). While this potentially affects
  Cosmic and later, too, the fix differs on later kernels (Bionic is not
  yet affected as it does not yet carry updates to the frags handling).

  == Fix ==

  For Xenial and Cosmic, the proposed fix would be additional changes to 
ip6_expipre_frag_queue(), taken from follow-up changes to ip_expire().
  For Disco, I would hold back because we have a backlog of stable patches 
there and depending on what got backported to 5.0.y there would be a simpler 
fix.
  For current development kernels, one just needs to ensure that the following 
upstream change is included: 47d3d7fdb10a "ip6: fix skb leak in 
ip6frag_expire_frag_queue()".

  == Testcase ==

  Unfortunately this could not be re-created locally. But a test kernel
  which had the proposed fix applied was showing good testing (see
  comment #37 and #38).

  == Risk of Regression ==

  The modified function is only called in rare cases and the positive
  testing in production would cover this. So I would consider it low.

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-06-19 Thread Dirk
I tested with Kernel:
Linux tor3 4.4.0-149-generic #175+lp1824687v4 SMP Mon May 27 17:21:02 UTC 2019 
x86_64 x86_64 x86_64 GNU/Linux

IPv6 is enabled and the system is under usual load. 
No crashes in 24h.
For me this is a clear indication that the problem is fixed. Before there where 
crashes all 2-4 hours.

Therefore Verified for Xenial.

How can I add tags ?

2019-06-18 Thread Ubuntu Kernel Bot
This bug is awaiting verification that the kernel in -proposed solves
the problem. Please test the kernel and update this bug with the
results. If the problem is solved, change the tag 'verification-needed-
xenial' to 'verification-done-xenial'. If the problem still exists,
change the tag 'verification-needed-xenial' to 'verification-failed-
xenial'.

If verification is not done by 5 working days from today, this fix will
be dropped from the source code, and this bug will be closed.

See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how
to enable and use -proposed. Thank you!

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-06-11 Thread Stefan Bader
I reverted the changes to Cosmic because that needs at least a different
approach. In that version the rbtree usage is not yet present and the
IPv4 expire function does the exactly same thing (increment the refcount
of the skb) and we have no hard evidence this actually causes crashes in
the 4.18 kernel. So for now only keep the xenial change.

  16.04/4.4 kernel crashes whenever that functions gets called (on busy
  systems this can be every 3-4 hours). While this potentially affects
  Cosmic and later, too, the fix differs on later kernels (Bionic is not
  yet affected as it does not yet carry updates to the frags handling).

  == Fix ==

  For Xenial and Cosmic, the proposed fix would be additional changes to 
ip6_expipre_frag_queue(), taken from follow-up changes to ip_expire().
  For Disco, I would hold back because we have a backlog of stable patches 
there and depending on what got backported to 5.0.y there would be a simpler 
fix.
  For current development kernels, one just needs to ensure that the following 
upstream change is included: 47d3d7fdb10a "ip6: fix skb leak in 
ip6frag_expire_frag_queue()".

  == Testcase ==

  Unfortunately this could not be re-created locally. But a test kernel
  which had the proposed fix applied was showing good testing (see
  comment #37 and #38).

  == Risk of Regression ==

  The modified function is only called in rare cases and the positive
  testing in production would cover this. So I would consider it low.

  After upgrading our server to this Kernel we experience frequent Kernel 
panics (Attachment).
  Every 3 hours.
  Our machine has a throuput of about 600 Mbits/s
  The Panics are around the area of ip6_expire_frag_queue.

  It seems similar to Bug Report in Debian.

  According to the bug finder of above bug it also occurred after using a

Thanks, I deployed the v4 debs on one server which was particularly
unstable, and it's still up after 1 day and 8 hours now. I'll deploy
more widely on Monday and Tuesday.

  Description:  Ubuntu 16.04.6 LTS
  Release:  16.04

  
  After upgrading our server to this Kernel we experience frequent Kernel 
panics (Attachment).
  Every 3 hours. 
  Our machine has a throuput of about 600 Mbits/s 
  The Panics are around the area of ip6_expire_frag_queue.

__pskb_pull_tail
ip6_dst_lookup_tail
_decode_session6
__xfrm_decode_session
icmpv6_route_lookup
icmp6_send

  
  It seems similar to Bug Report in Debian.
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=922488

  According to the bug finder of above bug it also occurred after using a 
Kernel with the change of
  rewrite ip6_expire_frag_queue()

  Intermediate solution. We disabled IPv6 on this machine to avoid further 
Panics.
  Please let me know what information is missing. The ubuntu-bug linux was

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-05-28 Thread Stefan Bader
So far I have not been successful to trigger the code path which leads to the 
crashes on my test system. I have, however been able to extend the patch I had 
in v2 in a way that makes me a bit more hopeful that it might get us somewhere. 
Potentially not the most optimized handling but that could wait. The problem is 
a bit that all the changes come from a set of changes where I am not sure 
upstream really tested the intermediate steps too well. Anyhow, you would find 
the new debs again at http://people.canonical.com/~smb/lp1824687/
I know it sucks, but I would appreciate if we could put that again into 
production stress.

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-05-21 Thread Stefan Bader
Spend a little more time on this yesterday. While it is somewhat clear that 
this results from fixing the original issue (now it crashes when releasing 
memory a little later), My past experience of looking at network issues like 
that is that memory dumps are of rather limited use as the reasons lie in the 
past and by the time crashes happen all the interesting state is already lost.
On the other hand I also would rather avoid making experiments in production 
environments (if that can be avoided). But I am not sure how much chance there 
is for that.

Thanks, quickly glancing at this it looks to be different as in crashing
now at a different occasion (when releasing a buffer). I will have to
take a closer look but probably not today.

2019-05-17 Thread Heikki Hannikainen
Unfortunately 4.4.0-144-generic #170+lp1824687v2 testing kernel still
crashes. I have 4 hardware instances running it now, there were 2 panics
(Australia, Sweden) within 24 hours. I installed linux-crashdump on them
after the first crash to get the panic logs reliably. Attached a log
from the second panic.

Sorry for the delay. I'm back in the office now and deploying the test
kernel today to a few servers, and to additional ones tomorrow if it's
OK on the first ones.

Just a reminder for the test kernel. If this can be tested soon, it
could make it into the next update cycle which starts next week. But for
that it has to be submitted before end of Wednesday.

2019-05-03 Thread Stefan Bader
>From the upstream discussion thread it looks like I was on the right
track (https://marc.info/?l=linux-netdev=155688404826002=2). For
confirmation I am building another set of test kernel packages and once
this can be confirmed will proceed to SRU this into the other series.
This looks to have remained unnoticed so far, so anything after 4.18 and
all the older kernels which have backported those changes would be
affected.

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-05-03 Thread Heikki Hannikainen
There is the kernel.org bug ticket which describes similar oopsing
through ip6_expire_frag_queue() in 4.9 and 4.19 kernels:
https://bugzilla.kernel.org/show_bug.cgi?id=202669

I also saw crashes on 4.15.0-48-generic on a server running the same
task; I don't have stack traces to show yet since they didn't get out to
the remote syslog server.

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-05-03 Thread Stefan Bader
As a status update: thanks for testing. I pity it did not help. So far I
was looking through all related changes in that set but could not find
anything that immediately stuck out. Thinking more over the crash
stacktrace it is a netfilter contrack timer expiring which causes a call
into ip6_expire_frag_queue() and that got rewritten in "ipv6: frags:
rewrite ip6_expire_frag_queue()" to use the first entry in the frag list
for sending an ICMP message. And before doing that, it calls skb_get()
which does increment the user refcount. That might actually be the issue
but it is still done that way in any kernel since v4.18 upstream. Could
be that nobody is using those under heavy ipv6 traffic, yet. Since I am
not that familiar with the network stack, I would like to reach out to
upstream with that question.

O.k. tested with the Kernel Provided. It does not improve the situtation.
Machine crashed first time after about 2hours - same error as always.
I rebootet it - took 2-3 hours until next crash.

Thanks for the updated Kernel.
Sorry for the late reply. Changes of ipmi where without success.

However I could install and boot your kernel
Linux version 4.4.0-144-generic (smb@kathleen) (gcc version 5.4.0 20160609 
(Ubuntu 5.4.0-6ubuntu1~16.04.10) ) #170+lp1824687v1 SMP Tue Apr 30 11:18:53 UTC 
2019 (Ubuntu 4.4.0-144.170+lp1824687v1-generic 4.4.176)

I activated IPv6 Traffic. We should see if the machine will panic.

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-04-30 Thread Stefan Bader
The issue is a check which is causing a oops/crash when a send buffer is
referenced more than once when calling pskb_expand_head(). As mentioned
in comment #18, this seems to be introduced by a series of patches
modifying the way fragments are handled.

The networking code is quite complex, so I am not sure whether some
detail I found actually is causing this issues (one backport claims to
drop some extraneous initialization in ipv6 which was not done in the
ipv4 counterpart), but I created a test kernel to see what happens. If
someone could give http://people.canonical.com/~smb/lp1824687/ a try and
let me know I would highly appreciate.

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-04-29 Thread Heikki Hannikainen
I have had this crash, with the ip6_expire_frag_queue stack trace, more
than 18 times since 2019-04-16 on more than 10 different servers in 8
different countries.  There have been some more crashes, but from these
ones the panic dump managed to go out to a remote syslog server where
it's easy to grep. Crash count by kernel version; these are on both
trusty and xenial:

2 crashes: 4.4.0-144-generic #170~14.04.1-Ubuntu
8 crashes: 4.4.0-145-generic #171-Ubuntu
8 crashes: 4.4.0-146-generic #172-Ubuntu

Downgrading to 4.4.0-143 now, as that build does not seem to have the
"ipv6: frags: rewrite ip6_expire_frag_queue()" change; it first appears
in 4.4.0-144-generic image.  I think by tomorrow it's clear whether that
kernel is stable as we're now having multiple crashes per day (last
crash 50 minutes ago).

These are routers running NAT & firewall & some applications, with
substantial IPv6 traffic.

Interestingly the crashes only happen on bare hardware. We have a much
larger number of VMs doing the same thing, most of them now running 
4.4.0-146, and none of them have crashed like this.  The hardware instances
do have a larger number of CPU cores, the VMs only have 2 or 4.

I am also seeing crashes on 4.15.0-48-generic hwe kernel running on xenial,
but no stack trace to show yet.

Attaching kernel stack trace file containing several crashes on various
servers (hessu-ipv6_expire_frag_queue-crashes.txt).

2019-04-17 Thread Stefan Bader
The latter means that you still have 4.4.0-143 around and could select
that if you had any way of interfacing with the booting server. So you
could go back and confirm the regression happened between 143 and 145.

About IPMI, I don't know how one would do that with Windows, but using a
Linux box, there is a package (name in Ubuntu, might vary on other
distros) called ipmitool which can be used to do the SOL session without
any java and from a terminal window. Of course in any case to see
anything you have to figure out which ttyS# on the server is mapped to
the SOL session (ttyS0 or ttyS1 usually). And then something like
"console=ttyS#,115200n8" has to be added to the default arguments in
/etc/default/grub to tell the kernel to re-direct the console to that
serial port.

just for completeness the command to initial a SOL session would be:
ipmitool -Ilanplus -H -U -P sol activate

I spend the better part of 2h to install java on an old windows to satisfy the 
IPMI needs.
I was able to start SOL. BUT it is just a black windows displaying nothing.
I give up. on this - sorry I do not know how to produce an better screenshot.
(Yes I googled). IPMI Viewer produced the same bad results.

Regards grub. Does this help:

2019-04-16 Thread Stefan Bader
Knowing which was the last good kernel would be good to minimize the delta of 
changes. Note that if you are able to interact with the grub loader at boot, 
you can go back to at least the previous kernel before the reboot.
For the trace it would be good to capture the full message. If the server has 
IPMI capabilities you could add a console= kernel command-line to have messages 
observable through SOL.

[Kernel-packages] [Bug 1824687] Re: 4.4.0-145-generic Kernel Panic ip6_expire_frag_queue

2019-04-15 Thread Dirk
regarding #2 I do not know which kernel ran before.

I assume linux-image-4.4.0-143 due to following apt history logs.
I however do not know if we rebooted.

I have a different type of server here with ubuntu. I can try to stress it and 
to see.
But I doubt I get the same quality of traffic since the other machine is an tor 
exit.

Bug description:
  Description:  Ubuntu 16.04.6 LTS
  Release:  16.04

  
  After upgrading our server to this Kernel we experience frequent Kernel 
panics (Attachment).
  Every 3 hours. 
  Our machine has a throuput of about 600 Mbits/s 
  The Panics are around the area of ip6_expire_frag_queue.

__pskb_pull_tail

icmpv6_route_lookup
icmp6_send

  
  It seems similar to Bug Report in Debian.
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=922488

  According to the bug finder of above bug it also occurred after using a 
Kernel with the change of
  rewrite ip6_expire_frag_queue()

  Intermediate solution. We disabled IPv6 on this machine to avoid further 
Panics.
  Please let me know what information is missing. The ubuntu-bug linux was

2019-04-15 Thread Stefan Bader
Which kernel version was used before (and did not show this crash)? Can
you reproduce the issue on a non-production server (which would allow to
experiment with the HWE (4.15) kernel)?

__pskb_pull_tail

  It seems similar to Bug Report in Debian.
  https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=922488

  According to the bug finder of above bug it also occurred after using a 
Kernel with the change of
  rewrite ip6_expire_frag_queue()

  Intermediate solution. We disabled IPv6 on this machine to avoid further 
Panics.
  Please let me know what information is missing. The ubuntu-bug linux was 
send. And I hope it is attached to this report.
