SELinux initial steps failing (?)

English Install/Boot/Login
1

Dear all,

after upgrading from 15.6 to 16.0 and installing and activating SELinux as described in Portal:SELinux/Setup I have an issue that after touch /.autorelabel

(1) On every boot SELinux: relabeling root filesystem is running, throwing three /sbin/setfiles: conflicting specifications all of them on hard links (files have the same inode)

(2) After boot /sbin/restorecon is running in the background.

(3) while for some boots the command

ausearch -m avc,user_avc,selinux_err,user_selinux_err -ts boot

returned nothing, now i am getting

type=AVC msg=audit(1779561826.073:38): avc:  denied  { sys_admin } for  pid=1580 comm="switcheroo-cont" capability=21  scontext=system_u:system_r:switcheroo_control_t:s0 tcontext=system_u:system_r:switcheroo_control_t:s0 tclass=capability permissive=1

which is strange, as the system has only one graphics card.

Is this how relabeling should work? My understanding was that this is a one-time procedure. What am I doing wrong and how can I resolve the “conflicting specifications” messages?
Also what should I do about the AVC message? Create a module to allow it, or just ignore it since I do not realy need switcheroo in this installation?

Best regards,

George

Deinstall switcheroo and taboo it:

 LANG=C zypper ll

so the problem is caused by switcheroo-control, which seems to be legitimate.

Only need switcheroo if you have more then one GPU’s

As root:
deinstall:

zypper rm switcheroo-control

now block it (set a lock on it):

zypper al switcheroo-control

See now

zypper ll

It is locked

I rebooted and

# ausearch -m avc,user_avc,selinux_err,user_selinux_err -ts boot
<no matches>

so the switcheroo-control issue has gone. This did not change the scanning of / as part of dracut-pre-pivot:

which takes 2:13 to complete. And after login I can observe restorecon running for a while:
