Description Matthew Farrellee 2011-11-04 11:00:48 EDT
+++ This bug was initially created as a clone of Bug #750818 +++

Description of problem:
When condor-vm-gahp runs a KVM/VM job, the following error can be seen in /var/log/message:

SELinux is preventing condor_vm-gahp (initrc_t) "setattr" to ./testvm.img (svirt_image_t). For complete SELinux messages. run sealert -l e57ca993-1ff2-45c2-bd24-ae2a0d7e573e

Excerpts from the output of sealert:

host=... type=AVC msg=audit(1320237390.206:506): avc:  denied  { setattr } for  pid=675 comm="condor_vm-gahp" name="testvm.img" dev=dm-0 ino=4751773 scontext=root:system_r:initrc_t:s0 tcontext=system_u:object_r:svirt_image_t:s0:c242,c576 tclass=file

host=... type=SYSCALL msg=audit(1320237390.206:506): arch=c000003e syscall=132 success=no exit=-13 a0=1cf42840 a1=7fffac450580 a2=0 a3=ea items=0 ppid=672 pid=675 auid=0 uid=0 gid=0 euid=64 suid=0 fsuid=64 egid=64 sgid=0 fsgid=64 tty=(none) ses=5 comm="condor_vm-gahp" exe="/usr/sbin/condor_vm-gahp" subj=root:system_r:initrc_t:s0 key=(null)

The job is successfully executed despite the error.

Job file:



# ls -Z /var/lib/libvirt/images/testvm.img 
-rwxr-xr-x  root root system_u:object_r:svirt_image_t:s0:c242,c576 /var/lib/libvirt/images/testvm.img

("restorecon -vF /var/lib/libvirt/images/testvm.img" was also executed but it did not change anything).

The error can be seen on RHEL5.x (5.7) only, not on RHEL 6.2.

I labeled condor_vm-gahp as virtd_exec_t which we have in RHEL6.
