| 7 | flowi structure:
|
| 8 |
|
| 9 | The secid member in the flow structure is used in LSMs (e.g. SELinux) to indicate
|
| 10 | the label of the flow. This label of the flow is currently used in selecting
|
| 11 | matching labeled xfrm(s).
|
| 12 |
|
| 13 | If this is an outbound flow, the label is derived from the socket, if any, or
|
| 14 | the incoming packet this flow is being generated as a response to (e.g. tcp
|
| 15 | resets, timewait ack, etc.). It is also conceivable that the label could be
|
| 16 | derived from other sources such as process context, device, etc., in special
|
| 17 | cases, as may be appropriate.
|
| 18 |
|
| 19 | If this is an inbound flow, the label is derived from the IPSec security
|
| 20 | associations, if any, used by the packet.
