Subject: [PATCH] Allow smbcontrol use additional socket types
|
||
|
|
|
||
|
|
Reference: https://gitbub.com/fedora-selinux/selinux-policy/commit/0269eebb529eef5288b4b6dd1c62604dbd230230
|
||
|
|
Conflict: NA
|
||
|
|
|
||
|
|
In order to set debug level, smbcontrol was allowed to:
|
||
|
|
- create and use udp socket
|
||
|
|
- create and use netlink route sockets, read route configuration state
|
||
|
|
|
||
|
|
AVC denials example:
