flowi structure:
|
|
|
|
The secid member in the flow structure is used in LSMs (e.g. SELinux) to indicate
|
|
the label of the flow. This label of the flow is currently used in selecting
|
|
matching labeled xfrm(s).
|
|
|
|
If this is an outbound flow, the label is derived from the socket, if any, or
|
|
the incoming packet this flow is being generated as a response to (e.g. tcp
|
|
resets, timewait ack, etc.). It is also conceivable that the label could be
|
|
derived from other sources such as process context, device, etc., in special
|
|
cases, as may be appropriate.
|
|
|
|
If this is an inbound flow, the label is derived from the IPSec security
|
|
associations, if any, used by the packet.
