[Kernel-packages] [Bug 1698747] Re: "vforkmany" test in the smoke test test suite will stuck on Xenial i386

2017-06-19 Thread Colin Ian King
This was introduced with upstream stress-ng commit:

commit f954db3afe8ae2dc9474908250d3a2c595200a94
Author: Colin Ian King 
Date:   Wed Jun 7 20:01:16 2017 +0100

stress-vforkmany: remove as many calls as possible

We should remove as many function calls so we don't clobber the stack.

Signed-off-by: Colin Ian King 

..the code added a wrapper process to ensure that kill'd vfork children
were respawned, however, the non-OOM-able setting on the vfork processes
were causing the OOM killer to reap everything except the vfork
children.

I've fixed this with upstream fix:

http://kernel.ubuntu.com/git/cking/stress-
ng.git/commit/?id=5f3c93335def9985d479e891f3eb5939c1dd3797

This now makes vfork processes OOM-able by default.

2017-06-19 Thread Colin Ian King
This results in OOM'ing and killing various services - I can reproduce
this right back to earlier 4.4 kernels, e.g. 4.4.0-59, so this is not a
regressions per se.

This one belongs to ubuntu_stress_smoke_test test suite, which will call
the stress-ng to perform this test.
