<center>Notable Changes</center>
</h2>
<ul>
<li>SLE Micro 5.4 is based on SLES 15 SP4 (like SLE Micro 5.3) but plus Maintenance Updates,</li>
<li>The default setting of SELinux for new installations has been changed from permissive to enforcing
mode,</li>
<li>PCP container integration in cockpit,</li>
<li>Podman was updated from 3.x to 4.3.1.</li>
</ul>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">As always, we highly recommend to check our
<a href="https://www.suse.com/releasenotes/x86_64/SLE-Micro/5.4/index.html" style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">Release Notes</a> for a complete
overview of the changes in this new version.
</p>
<h2 style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly; color: #30BA78">
<center>Debugging SELinux Denials</center>
</h2>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">SELinux will now be set to enforcing by default. That means that you might run into issues because
SELinux prevents you from doing something. This might then result in issues that are hard to debug
with the approaches you used up to this point.</p>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">If you run into strange issues have a look at the audit log to check for AVC entries like these:</p>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly"><em>type=AVC msg=audit(1669971354.731:25): avc: denied { create } for pid=1264 comm="ModemManager" scontext=system_u:system_r:modemmanager_t:s0 tcontext=system_u:system_r:modemmanager_t:s0 tclass=qipcrtr_socket permissive=0</em></p>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">These tell you that SELinux prevented something. You should also check the journal, as some of
these messages are only visible there.</p>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">The next step is to set the system to permissive mode and try again with executing <em>setenforce 0</em>
command, which switches SELinux to permissive immediately, or with changing the kernel command line
too include <em>enforcing=0</em> and rebooting. After that SELinux will log, but not prevent access. If it
works then you have confirmation that SELinux is the culprit.</p>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">If you ran in permissive mode you will need to relabel your system until you are in a good state
again, as permissive mode allows you to reach states that are not reachable otherwise. For that run
touch /etc/selinux/.autorelabel and reboot.</p>
<p style="font-family: 'Segoe UI', sans-serif; mso-line-height-rule: exactly">If you identify and issues open a bug for the security team with SELinux in the subject, the AVCs
you saw and step by step reproduction steps. We'll then work on this to get it fixed for future
Alpha and Beta snapshots.</p>
