Subject: [PATCH] locking: restrict sockets to mode 0600

The virtlockd daemon's only intended client is the libvirtd daemon. As
|
|
such it should never allow clients from other user accounts to connect.
|
|
The code already enforces this and drops clients from other UIDs, but
|
|
we can get earlier (and thus stronger) protection against DoS by setting
|
|
the socket permissions to 0600
|
|
|
|
Fixes CVE-2019-10132
