Add vm-pid to VIRT_CONTROL audit events
Last modified: 2012-06-20 02:47:42 EDT
Description of problem: In order to positively correlate all audit events to a qemu instance, we need to record the vm-pid on startup/shutdown. There is a patch upstream that does this: http://libvirt.org/git/?p=libvirt.git;a=commitdiff;h=98b01e8f2bf3dd3c8a8881f2a94af3f9d1a95620 Testing should be easy. start up a vm, run ausearch -m VIRT_CONTROL, then run ps -ef and see if the vm-pid field is a qemu process. (Or something like that.) Additional info: This is needed for the auvirt program in the 6.3 audit package.
Verified PASS with libvirt-0.9.10-1.el6. The vm-pid is the same as corresponding qemu process id. # virsh list --all Id Name State ---------------------------------------------------- 6 rhel6 running #ausearch -m VIRT_CONTROL ...snip... time->Wed Feb 15 14:36:26 2012 type=VIRT_CONTROL msg=audit(1329287786.381:110288): user pid=2557 uid=0 auid=4294967295 ses=4294967295 subj=system_u:system_r:virtd_t:s0-s0:c0.c1023 msg='virt=kvm op=start reason=restored vm="rhel6" uuid=4f2e1779-7040-702c-efd0-380e87f73a5d vm-pid=29067: exe=2F7573722F7362696E2F6C69627669727464202864656C6574656429 hostname=? addr=? terminal=? res=success' #ps aux|grep rhel6 qemu 29067 0.4 4.3 1323320 323504 ?
