Subject: [PATCH] mka: Disable peer detection timeout for PSK mode
|
|
|
41389a |
|
|
|
41389a |
The first peer may take a long time to come up. In PSK mode we are
|
|
|
41389a |
basically in a p2p system, and we cannot know when a peer will join the
|
|
|
41389a |
key exchange. Wait indefinitely, and let the administrator decide if
|
|
|
41389a |
they want to abort.
