Memory resource controller oom killing not functioning
Status in “linux” package in Ubuntu:
Invalid
Bug description:
This problem reproduces on Ubuntu 13.10 with a 3.11 kernel but, for
comparison, works ok on RHEL 7 with a 3.10 kernel.
Steps to reproduce:
1. Make a directory, for example /home/glyn/cgh1.
2. Switch to root user.
3. Attach the memory resource controller subsystem to a cgroup hierarchy:
# mount -t cgroup -o memory none /home/glyn/cgh1
4. cd /home/glyn/cgh1
5. Createa a child cgroup:
# mkdir example
6. cd example
7. check oom killing is enabled:
# cat memory.oom_control
oom_kill_disable 0
under_oom 0
8. Set a memory limit for the example cgroup of approx. 1 MB:
# echo 100 memory.limit_in_bytes
# cat memory.limit_in_bytes
1003520
9. Move the current process into the example cgroup and check it has
moved:
# echo $$ tasks
# cat tasks
7357
8449
# cat tasks
7357
8450
10. Run a process which will exceed 1 MB of memory:
# perl -e 'for ($i = 0; $i 10; $i++) { $foo .= A x (1024 * 1024); }'
#
This terminates successfully whereas it should have been killed. On
RHEL 7 (and on earlier Ubuntu versions I have tried), the results look
like this:
# perl -e 'for ($i = 0; $i 10; $i++) { $foo .= A x (1024 * 1024); }'
killed
#
I will attempt to reproduce this bug on an upstream kernel, but don't
want to lose the bug report during the upgrade, hence I am filing the
report now.

[Kernel-packages] [Bug 1303683] Re: Memory resource controller oom killing not functioning
This is not a bug.
It turns out the behaviour I was seeing was due to the fact that swap
accounting is disabled by default and so the perl process was swapping
rather than being killed when its RAM limit was reached.
If I turn swap off (swapoff -a), the process is killed correctly.
Similarly, if I inhibit swapping by setting memory.swappiness to 0 in
the example cgroup, the process is killed correctly.
Alternatively, if I turn swap accounting on (by setting
`GRUB_CMDLINE_LINUX=cgroup_enable=memory swapaccount=1` in
/etc/default/grub, running update-grub, and rebooting), then
memory.memsw.* files appear in the example cgroup. If I set
memory.limit_in_bytes and memory.memsw.limit_in_bytes both to 300,
then the perl process is killed correctly.

[Kernel-packages] [Bug 1303683] Re: Memory resource controller oom killing not functioning
It occurred to me that the behaviour observed could have been due to an
optimisation in a later version of perl, but Ubuntu 13.10 is running
perl v5.14.2 whereas RHEL 7 is running v5.16.3. It seems unlikely,
therefore, that the version of perl is significant to this problem.

[Kernel-packages] [Bug 1303683] Re: Memory resource controller oom killing not functioning
Note that the above instructions assuming swapping is off, otherwise
memory.memsw.limit_in_bytes would also need to be set to 100.
The above testing was done on a 3.11.0-17-generic kernel. Re-testing on
an upstream kernel, 3.14.0-031400-generic (3.14-trusty), showed the
same problem - the process which should have been killed oom again ran
successfully.

[Kernel-packages] [Bug 1303683] Re: Memory resource controller oom killing not functioning
Would it be possible for you to test the latest upstream kernel? Refer
to https://wiki.ubuntu.com/KernelMainlineBuilds . Please test the latest
v3.14 kernel[0].
If this bug is fixed in the mainline kernel, please add the following
tag 'kernel-fixed-upstream'.
If the mainline kernel does not fix this bug, please add the tag:
'kernel-bug-exists-upstream'.
If you are unable to test the mainline kernel, for example it will not boot,
please add the tag: 'kernel-unable-to-test-upstream'.
Once testing of the upstream kernel is complete, please mark this bug as
Confirmed.
Thanks in advance.

Title:
Memory resource controller oom killing not functioning
Status in “linux” package in Ubuntu:
Incomplete
Bug description:
This problem reproduces on Ubuntu 13.10 with a 3.11 kernel but, for
comparison, works ok on RHEL 7 with a 3.10 kernel.
Steps to reproduce:
1. Make a directory, for example /home/glyn/cgh1.
2. Switch to root user.
3. Attach the memory resource controller subsystem to a cgroup hierarchy:
# mount -t cgroup -o memory none /home/glyn/cgh1
4. cd /home/glyn/cgh1
5. Createa a child cgroup:
# mkdir example
6. cd example
7. check oom killing is enabled:
# cat memory.oom_control
oom_kill_disable 0
under_oom 0
8. Set a memory limit for the example cgroup of approx. 1 MB:
# echo 100 memory.limit_in_bytes
# cat memory.limit_in_bytes
1003520
9. Move the current process into the example cgroup and check it has
moved:
# echo $$ tasks
# cat tasks
7357
8449
# cat tasks
7357
8450
10. Run a process which will exceed 1 MB of memory:
# perl -e 'for ($i = 0; $i 10; $i++) { $foo .= A x (1024 * 1024); }'
#
This terminates successfully whereas it should have been killed. On
RHEL 7 (and on earlier Ubuntu versions I have tried), the results look
like this:
# perl -e 'for ($i = 0; $i 10; $i++) { $foo .= A x (1024 * 1024); }'
killed
#
I will attempt to reproduce this bug on an upstream kernel, but don't
want to lose the bug report during the upgrade, hence I am filing the
report now.
