Description of problem: I encounter this frequently; at least on every boot, but I suspect it pops up later too. This might be related to bug 1296150 Version-Release number of selected component: selinux-policy-3.13.1-168.fc24.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.5.0-0.rc1.git2.1.fc24.x86_64 type: libreport (In reply to Giulio 'juliuxpigface' from comment #1) > Description of problem: > I encounter this frequently; at least on every boot, but I suspect it pops > up later too. > > This might be related to bug 1296150 > Please disregard this description... It was not for this bug report but for another one. I apologize for the inconvenience it may have caused. Description of problem: This selinux alert appears right after start of the system. Version-Release number of selected component: selinux-policy-3.13.1-171.fc24.noarch Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.5.0-0.rc3.git3.1.fc24.x86_64 type: libreport This bug appears to have been reported against 'rawhide' during the Fedora 24 development cycle. Changing version to '24'. More information and reason for this action is here: https://fedoraproject.org/wiki/Fedora_Program_Management/HouseKeeping/Fedora24#Rawhide_Rebase Proposed as a Blocker for 24-final by Fedora user chrismurphy using the blocker tracking app because: This denial comes up on Workstation lives during live boot and post-install. selinux-policy-3.13.1-176.fc24.noarch Fedora-Workstation-Live-x86_64-24-20160305.0.iso. "SELinux and crash notifications There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop. " Pretty sure this is not an selinux-policy bug, but is systemd setting the label on /sys/fs/cgroup. Discussed at today's blocker review meeting [1]. Accepted as a Final blocker - it's a clear violation of "There must be no SELinux denial notifications or crash notifications on boot of or during installation from a release-blocking live image, or at first login after a default install of a release-blocking desktop."

You can provide feedback for this update here: https://bodhi.fedoraproject.org/updates/FEDORA-2016-8f142bb969 Description of problem: Booted the F24 Alpha 1.5 Workstation x86_64 live image in a KVM, this denial appeared as soon as the desktop came up. I do notice that I can't seem to cut/paste into or out of the VM - this denial may be why? Version-Release number of selected component: selinux-policy-3.13.1-176.fc24.noarch Additional info: reporter: libreport-2.6.4 hashmarkername: setroubleshoot kernel: 4.5.0-0.rc7.git0.2.fc24.x86_64 type: libreport Proposing as an Alpha freeze exception; avoiding an AVC out-of-the-box seems like a good idea, and if this would also fix copying/pasting into/out of a VM while running live, that's significant too. +1 FE Sure, +1 FE That's +3, marking accepted. The update has not yet gone stable. Please do not close the bug. If it's closed, we won't notice that it needs a stable push. selinux-policy-3.13.1-179.fc24 has been pushed to the Fedora 24 stable repository.

Description of problem: SELinux is preventing spice-vdagentd from 'getattr' accesses on the filesystem /sys/fs/cgroup. ***** Plugin catchall (100. confidence) suggests ************************** If you believe that spice-vdagentd should be allowed getattr access on the cgroup filesystem 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 spice-vdagentd /var/log/audit/audit.log | audit2allow -M mypol # semodule -i mypol.pp Additional Information: Source Context system_u:system_r:vdagent_t:s0 Target Context system_u:object_r:tmpfs_t:s0 Target Objects /sys/fs/cgroup [ filesystem ] Source spice-vdagentd Source Path spice-vdagentd Port <Unknown> Host (removed) Source RPM Packages Target RPM Packages Policy RPM selinux-policy-3.13.1-156.fc24.noarch Selinux Enabled True Policy Type targeted Enforcing Mode Enforcing Host Name (removed) Platform Linux (removed) 4.3.0-0.rc7.git1.1.fc24.x86_64 #1 SMP Tue Oct 27 16:50:25 UTC 2015 x86_64 x86_64 Alert Count 1 First Seen 2015-10-29 10:02:35 CET Last Seen 2015-10-29 10:02:35 CET Local ID 5defad19-42d3-407d-9b09-7560d6878e7c Raw Audit Messages type=AVC msg=audit(1446109355.534:570): avc: denied { getattr } for pid=699 comm="spice-vdagentd" name="/" dev="tmpfs" ino=9622 scontext=system_u:system_r:vdagent_t:s0 tcontext=system_u:object_r:tmpfs_t:s0 tclass=filesystem permissive=0 Hash: spice-vdagentd,vdagent_t,tmpfs_t,filesystem,getattr Version-Release number of selected component: selinux-policy-3.13.1-156.fc24.noarch Additional info: reporter: libreport-2.6.3 hashmarkername: setroubleshoot kernel: 4.3.0-0.rc7.git1.1.fc24.x86_64 type: libreport
