Hi guys.
I filed a bug report with RH's Bugzilla but nothing happened there thus thought I'd let - if SIGs read this list - you guys know that Samba 4.16 is broken, hard-crashes. For better picture - Samba is managed by IPA
What bug report? Can you point to it?
The only problem I know about is a missing SELinux policy extension for samba-dcerpcd daemon which prevent ipasam module from loading. samba-dcerpcd got a new SELinux context which is not allowed to do anything that ipasam is supposed to do: read /etc/krb5.conf, initialize openssl configuration, communicate with LDAP server, etc.
This is handled in https://bugzilla.redhat.com/show_bug.cgi?id=2096521 for RHEL 9.1 (C9S) and in https://bugzilla.redhat.com/show_bug.cgi?id=2096825 for RHEL 8.7 (C8S).
A workaround is to put SELinux into permissive mode until SELinux folks would produce a fix -- or apply a local policy extension described in the bugzillas.
Pretty much the same as what I showed below, is in that BZ - https://bugzilla.redhat.com/show_bug.cgi?id=2094975 I did not think it had to do with SELinux, which I put into permissive and still got a crash as below. Is not very critical as Samba from appstream repo (also 4.16) works, only no gluster's libgfapi.
many thanks,
