Description of problem: Recently updated from f21 to f22. Started a VM that I had created under f21 on the new installation. Version-Release number of selected component: selinux-policy-3.13.1-126.fc22.noarch Additional info: reporter: libreport-2.5.1 hashmarkername: setroubleshoot kernel: 4.0.2-300.fc22.x86_64 type: libreport Description of problem: Starting a VM Version-Release number of selected component: selinux-policy-3.13.1-126.fc22.noarch Additional info: reporter: libreport-2.5.1 hashmarkername: setroubleshoot kernel: 4.0.3-300.fc22.x86_64 type: libreport OK, it relates with lttng support. Are you able to create/start a virtual machine even this error? *** Bug 1221961 has been marked as a duplicate of this bug. *** *** Bug 1222190 has been marked as a duplicate of this bug. *** This error pops up, but the VMs start/stop correctly. It relates with #1222157. We need to add a support for it in SELinux policy but I believe we don't want to allow it until we get a separation on it by libvirt. Description of problem: I have two VMs set to start on host boot. This AVC denial notification occurred upon log-in. Version-Release number of selected component: selinux-policy-3.13.1-126.fc22.noarch Additional info: reporter: libreport-2.5.1 hashmarkername: setroubleshoot kernel: 4.0.3-300.fc22.x86_64 type: libreport (In reply to Miroslav Grepl from comment #7) > It relates with #1222157.

Not sure what you mean 'separation on it by libvirt' FWIW this doesn't seem to be anything explicitly used by libvirt or qemu, but instead used automatically by ceph/librados (which both libvirt and qemu link to). So I don't think this is something that libvirt's svirt labelling should explicitly know about How do these files get created with the wrong label? Is this the kernel creating the files? There's a similar issue WRT apparmor: https://bugs.launchpad.net/ubuntu/+source/ust/+bug/1404302 Turns out fedora ceph disabled the lttng bits in the most recent builds for other reasons, so duping to that: https://bugzilla.redhat.com/show_bug.cgi?id=1223319 *** This bug has been marked as a duplicate of bug 1223319 *** |
Description of problem: SELinux is preventing qemu-system-x86 from 'open' accesses on the file /dev/shm/lttng-ust-wait-5. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that qemu-system-x86 should be allowed open access on the lttng-ust-wait-5 file by default. Then you should report this as a bug. You can generate a local policy module to allow this access. Do allow this access for now by executing: # grep qemu-system-x86 /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context unconfined_u:unconfined_r:svirt_t:s0:c160,c405 Target Context system_u:object_r:tmpfs_t:s0 Target Objects /dev/shm/lttng-ust-wait-5 [ file ] Source qemu-system-x86 Source Path qemu-system-x86 Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-126.fc22.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.0.3-300.fc22.x86_64 #1 SMP Wed May 13 18:43:52 UTC 2015 x86_64 x86_64 Alert Count 5 First Seen 2015-05-15 12:07:59 CEST Last Seen 2015-05-15 12:08:19 CEST Local ID b1ad018c-283e-4d8d-8ae4-b22e4cfe615f Raw Audit Messages type=AVC msg=audit(1431684499.522:567): avc: denied { open } for pid=2840 comm="qemu-system-x86" path="/dev/shm/lttng-ust-wait-5" dev="tmpfs" ino=21718 scontext=unconfined_u:unconfined_r:svirt_t:s0:c160,c405 tcontext=system_u:object_r:tmpfs_t:s0 tclass=file permissive=0 Hash: qemu-system-x86,svirt_t,tmpfs_t,file,open Version-Release number of selected component: selinux-policy-3.13.1-126.fc22.noarch Additional info: reporter: libreport-2.5.1 hashmarkername: setroubleshoot kernel: 4.0.3-300.fc22.x86_64 type: libreport
