I installed the latest batch of updates for F28 tonight. Since that
included a new kernel (4.16.10-300.fc28), I rebooted. The system came up
with the GDM panic screen [1]. I rebooted into the previous kernel
thinking that something might be wrong with the new one. Same result. I
rebooted again and added enforcing=0 to the kernel boot line. That
worked. I did a full SELinux relabel immediately afterwards. Nothing
relevant changed labels.
The SELinux Alert Browser says there are no alerts. Journalctl shows this:
systemd[1071]: selinux: avc: denied { status } for auid=n/a uid=42 gid=42
cmdline="/usr/libexec/gdm-x-session gnome-session --autostart
/usr/share/gdm/greeter/autostart"
scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023
tcontext=unconfined_u:unconfined_r:unconfined_t:s0-s0:c0.c1023
tclass=system permissive=0
followed a short time later by this:
audit[1405]: AVC avc: denied { map } for pid=1405 comm="gnome-session-c"
path="/dev/nvidiactl" dev="devtmpfs" ino=20616
scontext=system_u:system_r:xdm_t:s0-s0:c0.c1023
tcontext=system_u:object_r:xserver_misc_device_t:s0
tclass=chr_file permissive=0
And there are several more minor variations on that last one in the logs.
Just thought everybody should know ASAP.
Footnotes:
[1] Which is totally useless, by the way. It says "Oh no! Something went
wrong!" (Great. *WHAT* went wrong?) and informs me that I must logout. I
wasn't logged in. There's a nice logout button there, but it can't be
pressed. There is no mouse pointer. No keyboard shortcut that I can think
of causes the button to change appearance. Even if I did manage to press
it, what exactly would that do? I'm already not logged in!
