2724 | * This code has a bug, which requires creating a separate | |
2725 | * nl80211 socket to fix: | |
2726 | * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or | |
2727 | * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel | |
2728 | * before (!) we listen to it, because we only start listening | |
2729 | * after we send our scan request. | |
2730 | * | |
2731 | * Doing it the other way around has a race condition as well, | |
2732 | * if you first open the events socket you may get a notification | |
2733 | * for a previous scan. | |
2734 | * | |
2735 | * The only proper way to fix this would be to listen to events | |
2736 | * before sending the command, and for the kernel to send the | |
2737 | * scan request along with the event, so that you can match up | |
2738 | * whether the scan you requested was finished or aborted (this | |
2739 | * may result in processing a scan that another application | |
2740 | * requested, but that doesn't seem to be a problem). | |
2741 | * | |
2742 | * Alas, the kernel doesn't do that (yet). | |
