Sorry for the delay, bisecting took longer than planned, but I now have
the result:

i40e: fix handling of HW ATR eviction
The bad news is that this patch pretty certainly isn't directly the
culprit, as it only fixes (and re-enables) features that seem to have
been messed up earlier. So not sure how to proceed now, probably need to
discuss this with upstream developers?

Title:
Servers going OOM after updating kernel from 4.10 to 4.13
Status in linux package in Ubuntu:
Triaged
Status in linux source package in Artful:
Triaged
Bug description:
We are seeing this on multiple servers after upgrading from previous
4.10 series HWE kernels to the new 4.13 HWE series. With the new
kernel, free memory is continously decreasing at a high rate and the
servers start swapping and finally OOMing services within days. With
the 4.10 kernel, decrease of free memory is slower and stabilizes
after a while.
Latest kernel tested is linux-image-4.13.0-32-generic but the issue
also affects older kernels from that series, tested back to linux-
image-4.13.0-19-generic. No issue with linux-image-4.10.0-42-generic.
The servers are running as OpenStack controller nodes using either
Ocata or Pike UCA plus ceph. See attached graph for the memory
behaviour.
