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.
