description |
A simple stress test conducted on a KVM guest running standard updated Lucid with vsftpd demonstrates that memory is continuously used up until OOM Killer starts to protect the system. If test is terminated before that point is reached then memory is freed only after several hours. This does not occur with the 2.6.35 kernel (LTS backported kernel).
The test is started in this way:
$ for i in 1 2 3 4 5 6 7 8 ; do ./feedftp $i >/dev/null & done
What is observed during the test is that /proc/vmallocinfo grows continually with lines like the following being added:
0xffffe8ffff800000-0xffffe8ffffa00000 2097152 pcpu_get_vm_areas+0x0/0x790 vmalloc
0xffffe8ffffa00000-0xffffe8ffffc00000 2097152 pcpu_get_vm_areas+0x0/0x790 vmalloc
0xffffe8ffffc00000-0xffffe8ffffe00000 2097152 pcpu_get_vm_areas+0x0/0x790 vmalloc
Attached:
- test script (see feedftp)
- tarball containing the file at various times during the test (see vmallocinfo.32.tar)
- dmesg output showing OOM Killer at work (see dmesg-oom.32.txt)

A simple stress test conducted on a KVM guest running standard updated Lucid with vsftpd demonstrates that memory is continuously used up until OOM Killer starts to protect the system (after ~12 min on my system). If test is terminated before that point is reached then memory is freed only after several hours. If vsftpd is stopped then memory is freed (after ~10 min on my system).
This does not occur with the 2.6.35 kernel (LTS backported kernel).
The test is started in this way:
$ for i in 1 2 3 4 5 6 7 8 ; do ./feedftp $i >/dev/null & done
What is observed during the test is that /proc/vmallocinfo grows continually with lines like the following being added:
0xffffe8ffff800000-0xffffe8ffffa00000 2097152 pcpu_get_vm_areas+0x0/0x790 vmalloc

SRU justification:
Impact: With activated network namespace (CONFIG_NET_NS) support it is possible to create new namespaces much faster than cleaning them up. This can lead to memory pressure and in the case of vsftp it is easily possible to bring down the server by just repeatedly connecting to it.
Fix: The issue was fixed by a long series of changes to make cleanup quicker. The vast amount of changes makes them unsuited for SRU. So it was decided that the safest way for a 2.6.32 based kernel is to turn that feature off (it was considered experimental until 2.6.37 anyway).
Testcase: Se report.

A simple stress test conducted on a KVM guest running standard updated Lucid with vsftpd demonstrates that memory is continuously used up until OOM Killer starts to protect the system (after ~12 min on my system). If test is terminated before that point is reached then memory is freed only after several hours. If vsftpd is stopped then memory is freed (after ~45 min on my system).
This does not occur with the 2.6.35 kernel (LTS backported kernel).
The test is started in this way:

What is observed during the test is that /proc/vmallocinfo grows continually with lines like the following being added:
