The virtlockd daemon's only intended client is the libvirtd daemon. As
|
|
|
9b85a9 |
such it should never allow clients from other user accounts to connect.
|
|
|
9b85a9 |
The code already enforces this and drops clients from other UIDs, but
|
|
|
9b85a9 |
we can get earlier (and thus stronger) protection against DoS by setting
|
|
|
9b85a9 |
the socket permissions to 0600
