Unfortunately I have no control over the host, so I cannot test dom0. I could
only test inside a single domU.

I can confirm that applying 1adc34adc3447c34926994b87db5d929f5ab45b5 on top of
Debian’s 4.9.110-1 kernel solves the issue here on a Xen PV guest.

Bug#871608: linux-image-4.9.0-3-amd64: Linux kernel should handle decreasing cpu steal clock counter gracefully

[Michael Laß]

There is currently a discussion on LKML and xen-devel about this issue:
https://lkml.org/lkml/2017/10/10/182

Maybe this will result in some backportable fix.

Indeed this patch is not included upstream and won’t be as it does not apply to 
the current development branch. See the following brief discussion on this on 
Linux stable: http://www.spinics.net/lists/stable/msg186915.html

The main issue here is the conversion between nsecs and cputime and how this 
behaves when the calculated difference in steal time overflows, i.e. decreases. 
In this case cpustat does not overflow and therefore decrease as well but 
instead increases by a large number. In Linux 4.11 the conversion between nsecs 
and cputime is entirely gone, which should lead to a backwards running cpustat 
counter without further issues (I have not actually tested this):

2b1f967d80e8e5d7361f0e1654c842869570f573  sched/cputime: Complete nsec 
conversion of tick based accounting

This change seems to be only the last commit of a larger change though and I’m 
not sure if this larger change is suitable for backporting.

I agree that it would be nice to have a patch which has undergone a good review 
process. Unfortunately I cannot provide that. I also cannot estimate how many 
people are affected by this issue considering that it did not attract attention 
over the last year.

Bug#851214: images attached to emails are embedded with task=1 instead of task=mail

[Michael Laß]

Hi,

this is a duplicate of #843795. The workaround shown here would actually revert 
parts of a critical security fix for CVE-2016-4069. Instead, the solution 
mentioned in #843795 should be implemented and pushed via Wheezy LTS.

Cheers,
Michael
