| 3 | Subject: [PATCH] mesh: allow processing authentication frames in blocked state |
| 4 | |
| 5 | If authentication fails repeatedly e.g. because of a weak signal, the link |
| 6 | can end up in blocked state. If one of the nodes tries to establish a link |
| 7 | again before it is unblocked on the other side, it will block the link to |
| 8 | that other side. The same happens on the other side when it unblocks the |
| 9 | link. In that scenario, the link never recovers on its own. |
| 10 | |
| 11 | To fix this, allow restarting authentication even if the link is in blocked |
| 12 | state, but don't initiate the attempt until the blocked period is over. |
