Subject: [PATCH] core: reload SELinux label cache on daemon-reload
|
||
|
|
|
||
|
|
Reloading the SELinux label cache here enables a light-wight follow-up of a SELinux policy change, e.g. adding a label for a RuntimeDirectory.

|
|
|
||
|
|
Closes: #13363
|
||
|
|
(cherry picked from commit a9dfac21ec850eb5dcaf1ae9ef729389e4c12802)

||
|
|
|
||
|
|
Resolves: #1888912
