1767 | * WARNING: DO NOT COPY THIS CODE INTO YOUR APPLICATION | |
1768 | * | |
1769 | * This code has a bug, which requires creating a separate | |
1770 | * nl80211 socket to fix: | |
1771 | * It is possible for a NL80211_CMD_NEW_SCAN_RESULTS or | |
1772 | * NL80211_CMD_SCAN_ABORTED message to be sent by the kernel | |
1773 | * before (!) we listen to it, because we only start listening | |
1774 | * after we send our scan request. | |
1775 | * | |
1776 | * Doing it the other way around has a race condition as well, | |
1777 | * if you first open the events socket you may get a notification | |
1778 | * for a previous scan. | |
1779 | * | |
1780 | * The only proper way to fix this would be to listen to events | |
1781 | * before sending the command, and for the kernel to send the | |
1782 | * scan request along with the event, so that you can match up | |
1783 | * whether the scan you requested was finished or aborted (this | |
1784 | * may result in processing a scan that another application | |
1785 | * requested, but that doesn't seem to be a problem). | |
1786 | * | |
1787 | * Alas, the kernel doesn't do that (yet). | |
