Public bug reported:
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 1000000 > 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.
