Description Chris Murphy 2017-02-28 05:23:22 UTC
Description of problem:

Feb 28 00:17:20 localhost.localdomain audit[17896]: AVC avc:  denied  { mounton } for  pid=17896 comm="(-localed)" path="/proc/mtrr" dev="proc" ino=4026531961 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:mtrr_device_t:s0 tclass=file permissive=1



Version-Release number of selected component (if applicable):
Fedora-Workstation-Live-x86_64-Rawhide-20170226.n.0.iso
selinux-policy-3.13.1-241.fc26.noarch

How reproducible:
Always, happens during tail end of installation


Steps to Reproduce:
1. Install Fedora
2.
3.

Actual results:

Near tail end of installation, dracut building initramfs, there is a notification in gnome-shell of an SELinux alert.


Expected results:

No alert.

Additional info:

SELinux is preventing (-localed) from mounton access on the file /proc/mtrr.

*****  Plugin catchall (100. confidence) suggests   **************************

If you believe that (-localed) should be allowed mounton access on the mtrr 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:
# ausearch -c '(-localed)' --raw | audit2allow -M my-localed
# semodule -X 300 -i my-localed.pp

Comment 1 Fedora Blocker Bugs Application 2017-02-28 05:26:01 UTC
Proposed as a Blocker for 26-final by Fedora user chrismurphy using the blocker tracking app because:

 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.

Comment 2 Geoffrey Marr 2017-03-06 18:43:00 UTC
Discussed during the 2017-03-06 blocker review meeting: [1]

The decision to classify this bug as an Accepted Blocker (Final) and an Accepted Freeze Exception (Alpha) as it violates the following blocker criteria:

"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."

It is also visible enough on Alpha release to warrant the classification as a Freeze Exception.
