Description Bernardo Donadio 2016-06-29 19:07:17 EDT
Description of problem:
After a fresh F24 install, SELinux complains that bluez-5.40-1 (specifically, the /usr/libexec/bluetooth/bluetoothd binary) wants to have mounton access on /etc (not any subdir, but the /etc itself), despite having no sane justification for doing so.

As intended, SELinux blocks this request. Even though not side effect is seen on my system, other have reported that their capability to use bluetooth was impaired, as per bug #1341753.

The AVC denial is the following, and the system was put in permissive mode in order to confirm the issue:
type=AVC msg=audit(1467239211.21:93): avc:  denied  { mounton } for  pid=1091 comm="(uetoothd)" path="/etc" dev="dm-0" ino=783362 scontext=system_u:system_r:init_t:s0 tcontext=system_u:object_r:etc_t:s0 tclass=dir permissive=1

No other AVC is logged even when permissive mode is enabled.

In my case, the PID 1091 proccess is, indeed, /usr/libexec/bluetooth/bluetoothd, which was started by init.

Version-Release number of selected component (if applicable): bluez-5.40-1.fc24.x86_64

How reproducible: Always. Reproducible on all three Fedora 24 systems of mine.

Steps to Reproduce:
1. Install a fresh F24 system and start the system.
2. The above pasted AVC will be logged in the auditd log.

Expected results:
No package should need to mount anything on /etc. This access request should be removed.
