F23 -> Rawhide upgrade fails to start GDM

[Richard Bradfield]

Hi all,

This may have been an insane proposition, so I'm asking here before I go
near bugzilla. 

I installed a clean F23 beta machine, then used dnf system upgrade to
try and move up to Rawhide. 

When I rebooted the system, I got the 'Oh no! Something has gone wrong'
screen, which repeats if I try and relaunch GDM. 

The only relevant error in the journal is:
Glib: g_hash_table_find: assertion 'version == hash_table->version'
failed

Setting 'setenforce 0', or setting selinux to permissive in the config
allows everything to work normally. 

I have tried relabelling the filesystem. 

Is this an insane unsupportable upgrade path or could I have found an
actual bug?

Those are not mutually exclusive options. This looks like a bug, but
fixing it will probably not be high priority when poeople are working
on F23 release.

Have a look at
https://fedoraproject.org/wiki/SELinux/Troubleshooting
and read the part about dontaudit rules. If you don't see any avcs,
it might because of that.

Yeah, I am/was seeing this in rawhide as well.

Here at least I see a crash in xwayland... 
( https://bugzilla.redhat.com/show_bug.cgi?id=1266637 ) 
then it dies in enforcing mode.

This is several real bugs. :) 

It seems if xwayland doesn't crash things work enforcing, but if it
does the fallback to X doesnt work right in enforcing mode. 

I've not yet filed the selinux bug... I'll try later today, or if you
can see what avc's you see and file it that would be great.

Unfortunately updating Mesa hasn't worked for me. I disabled dontaudit
and pasted a journal log from an attempt to restart GDM with SElinux in
Enforcing mode [1]. 

Apologies for how long it is, I have no way of telling which AVCs are
relevant so I thought it best to just paste the whole thing.

BTW With updated Mesa, pressing spacebar several times to close to Oh-No
message gets me finally to login screen ...
