Move wpa_supplicant specific scan code away from src/drivers This fits better in wpa_supplicant/scan.c. Couple of remaining scan_helpers.c functions are currently used in driver wrappers, but they can likely be removed in the future.

Validate WEP key lengths based on driver capabilities The nl80211 driver interface does not allow 128-bit WEP to be used without a vendor specific cipher suite and no such suite is defined for this purpose. Do not accept WEP key length 16 for nl80211 driver interface forn ow. wext-interface can still try to use these for backwards compatibility. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

void wpa_supplicant_req_scan(struct wpa_supplicant *wpa_s, int sec, int usec);
Add delayed scheduled scan request When initializing, the scheduled scan code was being called before everything is ready. With normal scans, the first scan round is delayed, so the initialization is finished by the time it really starts. Add a function that can be used to request a delayed scheduled scan. The scan will only start after the specified time has elapsed. Call this function instead of starting the scheduled scan directly during driver initialization.

Add scheduled scan driver operations In new Linux kernel versions (>=3.0), nl80211 adds scheduled scan capability. In order to use this feature to its full extent, we need to support it in the wpa_supplicant core, so that it can also be used by other drivers. This commit adds initial scheduled scan support operations and events. Signed-off-by: Luciano Coelho <coelho@ti.com>

void wpa_supplicant_cancel_scan(struct wpa_supplicant *wpa_s);
Cancel delayed scheduled scan when wpa_supplicant cleans up Because a delayed scheduled scan will access the members of struct wpa_supplicant which is freed and this can result in a crash, wpa_supplicant needs to cancel delayed scheduled scan during cleanups.

Remove src/drivers/scan_helpers.c Most of this file was already moved into wpa_supplicant/scan.c and we can remove the file completely by having couple of small helper functions copied to the remaining users outside core wpa_supplicant code.

P2P: Allow GO to be discovered based on Beacon frame This fixes some P2P-join-a-group cases where GO may have been discovered based on passive scan or non-P2P scan. P2P IEs may have been received from a Beacon frame in such a case and that information can be used to create a P2P peer entry, e.g., to allow provision discovery exchange to be completed.

Add BSSID filter for testing purposes wpa_supplicant can now be configured to filter out scan results based on a BSSID filter. Space-separated set of allowed BSSIDs can be set with wpa_cli set bssid_filter command. Filtering mechanism can be disabled by setting this variable to an empty list. When set, only the BSSes that have a matching entry in this list will be accepted from scan results. Signed-hostap: Jouni Malinen <jouni@qca.qualcomm.com>

Update scan interval gracefully When the scan interval is changed the new interval is effective after the old interval timer fires off one last time. This can cause an unacceptable long delay when updating the interval. Change this behaviour to use MIN(left of old interval, new interval) for the scan interval following the interval change.

P2P: Postpone P2P scan only if station mode scan is pending sta_scan_pending was supposed to be accurate enough for determining whether a P2P scan needs to be postponed. However, it has turned out that there were cases where sta_scan_pending was not cleared properly. While the known cases have now been addressed, it is possible that some other cases may still exist. To avoid issues with P2P operationg getting stuck, verify more carefully that there is a real pending station mode scan (either in progress or scheduled to be requested).

int wpas_scan_scheduled(struct wpa_supplicant *wpa_s);
Handle legacy scan interruption of sched_scan/PNO While starting from PNO start context, the scheduled scan was not setting the flag wpa_s->scanning. This was resulting in the subsequent SCAN command to proceed further and send command to nl80211/cfg80211. The expected behavior of cancelling sched_scan was not happening here. While sched_scan is in progress and a legacy scan comes on the cli/socket, the sched_scan is cancelled and normal scan is allowed to continue. However, sometimes sched_scan cancelled event comes a bit delayed and we will send out the scan command before the wpa_s->scanning is cleared. Instead, reschedule the incoming scan req if the wpa_s->scanning shows that it is still in progress. Signed-hostap: Jithu Jance <jithu@broadcom.com>
