Hi All
I have tried DU with kernels 5.1.10, 5.1.12 and 5.1.15. After reboot I get message "SELinux default policy relabel is required" and after while system reboots. On next very slow boot it shows all kind of errors, which do not appear in dmesg later, and eventualy boots as CLI. After logging in boot messages continue to appear occasionaly and system does not respond.

Use

Code: [Select]
selinux=0
as a boot option!

@dibl: normally the SELINUX things should not be relevant in a installed system - just because SELINUX is activated, but not strict - it was a problem for ISOs - so the kernel parameter is right :)

https://git.siduction.org/extra/pyfll/commit/489cd640acb1aa77360bc11273def74fcb29770f

Anyways - i would like to know the the SELINUX configuration of this particular installation.

@melmarker -- is there more to see than this?

Code: [Select]
don@n5110:~$ cat /etc/selinux/config
# This file controls the state of SELinux on the system.
# SELINUX= can take one of these three values:
# enforcing - SELinux security policy is enforced.
# permissive - SELinux prints warnings instead of enforcing.
# disabled - No SELinux policy is loaded.
SELINUX=permissive
# SELINUXTYPE= can take one of these two values:
# default - equivalent to the old strict and targeted policies
# mls     - Multi-Level Security (for military and educational use)
# src     - Custom policy built from source
SELINUXTYPE=default

# SETLOCALDEFS= Check local definition changes
SETLOCALDEFS=0
don@n5110:~$

No - the entry
Code: [Select]
SELINUX=permissive
should do the trick - all the things that would be otherwise enforced result only in warnings.

It must be a hardware-related compatibility issue, because I have had no such problem on 4 other kinds of hardware, all fully updated. Just this Dell laptop.  But selinux=0 fixed it.

On my siduction system that config file is missing:

Code: [Select]
# LANG=C ls -al /etc/selinux/
total 20
drwxr-xr-x   2 root root  4096 Mai  13 00:49 .
drwxr-xr-x 157 root root 12288 Jun  28 20:48 ..
-rw-r--r--   1 root root  2041 Sep  15  2017 semanage.conf

What could be the reason?

@samoht - if /etc/selinux/config isn't there - it isn't there - in other words: the file is not provided by any package. so it seems that it is created on the fly by some unknown selinux package

To be blunt: I fucking hate such packaging practices.

When I looked at my other systems, I found one configured like @samoht.

@dibl: it would be worth to search where the configuration file comes from -  i really hate it to create such things on the fly or copy it from elsewhere. But i hate the pyfll things as in "we do a heredoc and cat it right in and nobody knows where it comes from" most

PS: And in case of SElinux filing a grave bug against would be appropriate.

I would be willing to file a bug, but I'm not sure who to blame.  The Dell was running perfectly on kernel 5.0.14. When I upgraded to the first kernel 5.1, it broke.  The errors came from selinux, but it appears that a change in the kernel triggered the errors.  And @kole reports different errors than I saw, so there's a complication.

firsthand i see the problem in the "new" selinux configuration file - fuck, where does it come from? - Seems to be introduced some month ago. Right now i was to busy to search for ... :)

hrm - the fuck is all about this file - it is hard to search for, even if one has a clue where it come from, there are not much possible packages.
