Subject: [PATCH 07/11] logging: restrict sockets to mode 0600
|

MIME-Version: 1.0

The virtlogd 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
|
