2043 | * WARNING: DO NOT COPY THIS CODE INTO YOUR APPLICATION | |
2044 | * | |
2045 | * This code has a bug, which requires creating a separate | |
2046 | * nl80211 socket to fix: | |
2047 | * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or | |
2048 | * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel | |
2049 | * before (!) we listen to it, because we only start listening | |
2050 | * after we send our scan request. | |
2051 | * | |
2052 | * Doing it the other way around has a race condition as well, | |
2053 | * if you first open the events socket you may get a notification | |
2054 | * for a previous scan. | |
2055 | * | |
2056 | * The only proper way to fix this would be to listen to events | |
2057 | * before sending the command, and for the kernel to send the | |
2058 | * scan request along with the event, so that you can match up | |
2059 | * whether the scan you requested was finished or aborted (this | |
2060 | * may result in processing a scan that another application | |
2061 | * requested, but that doesn't seem to be a problem). | |
2062 | * | |
2063 | * Alas, the kernel doesn't do that (yet). | |
