2366 | * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or | |
2367 | * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel | |
2368 | * before (!) we listen to it, because we only start listening | |
2369 | * after we send our scan request. | |
2370 | * | |
2371 | * Doing it the other way around has a race condition as well, | |
2372 | * if you first open the events socket you may get a notification | |
2373 | * for a previous scan. | |
2374 | * | |
2375 | * The only proper way to fix this would be to listen to events | |
2376 | * before sending the command, and for the kernel to send the | |
2377 | * scan request along with the event, so that you can match up | |
2378 | * whether the scan you requested was finished or aborted (this | |
2379 | * may result in processing a scan that another application | |
2380 | * requested, but that doesn't seem to be a problem). | |
2381 | * | |
2382 | * Alas, the kernel doesn't do that (yet). | |
