1490 | * | |
1491 | * This code has a bug, which requires creating a separate | |
1492 | * nl80211 socket to fix: | |
1493 | * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or | |
1494 | * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel | |
1495 | * before (!) we listen to it, because we only start listening | |
1496 | * after we send our scan request. | |
1497 | * | |
1498 | * Doing it the other way around has a race condition as well, | |
1499 | * if you first open the events socket you may get a notification | |
1500 | * for a previous scan. | |
1501 | * | |
1502 | * The only proper way to fix this would be to listen to events | |
1503 | * before sending the command, and for the kernel to send the | |
1504 | * scan request along with the event, so that you can match up | |
1505 | * whether the scan you requested was finished or aborted (this | |
1506 | * may result in processing a scan that another application | |
1507 | * requested, but that doesn't seem to be a problem). | |
1508 | * | |
1509 | * Alas, the kernel doesn't do that (yet). | |
