Subject: PROBLEM: kernel memory subsystem incorrectly invokes OOM killer under certain situations
Hi linux-kernel,
[1.] One line summary of the problem:
kernel memory subsystem incorrectly invokes OOM killer under certain situations
[2.] Full description of the problem/report:
My guess is that whatever invokes the OOM killer is incorrectly
"deciding" that memory allocated for disk cache operations cannot be
"reclaimed", or, the oom killer code itself is incorrectly killing
processes when the cause of the memory exhaustion is the disk cache
subsystem (and not a runaway process).
Specifically - I have a RedHat AS4u5 2.6.9-55.0.6.ELsmp system with
4gigs RAM, running vmware 1.0.4, and another AS4 guest, which has 3
virtual SCSI drives. The following guest command reliably causes the
host OOM killer to terminate my vmware process:
dd if=/dev/sdb of=/deb/sdc
(to clone the contents of a 16gb virtual disk). The host has one 2TB
file system only.
While it's easiest to use vmware to demonstrate the problem, this does
not appear to be a problem with vmware itself.
[3.] Keywords (i.e., modules, networking, kernel):
/usr/src/redhat/BUILD/kernel-2.6.9/linux-2.6.9/mm/oom_kill.c
OOM killer
[4.] Kernel version (from /proc/version):
Linux version 2.6.9-55.0.6.ELsmp (brewbuilder@...0-bc2-3.build.redhat.com) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-8)) #1 SMP Thu Aug 23 11:11:20 EDT 2007
[5.] Output of Oops.. message (if applicable) with symbolic information
resolved (see Documentation/oops-tracing.txt)
Here's the messages output showing the offending oom-kill.

[6.] A small shell script or example program which triggers the
problem (if possible)
1. install RedHat AS4
2. install vmware 1.0.4 (same problem with 1.0.1, 1.0.2, and 1.0.3)
3. install AS4 again as a guest
4. configure 2 extra SCSI drives, and put at least 16gb of junk onto
one.
5. issue the "dd" command to copy one disk to another
6. observe the host will OOM-kill the vmware-vmx without warrant :-)
Here's an example of the guest (from the "top" command) before an
unwarranted oom-kill:-

[X.] Other notes, patches, fixes, workarounds:
This seems to fix the problem with no side effects:
echo 0 > /proc/sys/vm/oom-kill
Obviously - it's a better idea to hunt down the reason for the
unwarranted call rather than simply making the call do nothing...
At least one Internet posting I found through google suggested this
bug can be used by unprivileged users to kill random privileged
processes on a local machine, so there may be security implications if
this can be verified.
