b02fe7ff32 Interworking: Add commands for network selection
This adds the basic mechanism for running through network selection:
scan, ANQP fetch, network selection, and connection. Actual rules for
network selection and the creation of the network block are still
missing, but will be added in separate commits.

afc064fe7a Interworking: Add ANQP query requests
Add mechanism for using GAS/ANQP to query Interworking related
information from APs. The received information is stored in the BSS
table and can be viewed with ctrl_iface BSS command.

New ctrl_iface command ANQP_GET can be used to fetch ANQP elements from
a specific AP. Additional commands FETCH_ANQP and STOP_FETCH_ANQP can be
used to initiate and stop an iteration through all APs in the BSS table
that indicate support Interworking to fetch ANQP elements from them.

6a90053cdf 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.

bd525934e5 nl80211: Add support for sched_scan filtering
Use the SSID filter list passed in the scheduled scan request down to

SSIDs. Some kernel drivers can use this information to offload the
SSID filter to the hardware, helping with reducing the power

cbdf3507e9 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.

6758b1677a nl80211: Use shorter monitor interface name for P2P GO
Currently the P2P Interface name[p2p-%s-%d] is reset when the P2P
Interface name reaches the "IFNAMSIZ" limit. Monitor interface name is
derived from p2p interface name with the addition of few characters
[mon.p2p-%s-%d] and hence Monitor interface name hits IFNAMSIZ limit
before P2P Interface name. Rename the monitor interface name to
mon-%s-%d to reduce the length to same with p2p-%s-%d.

8666585b9e Disconnect STA when it fails to get added in kernel driver/firmware
Data path for stations that get successfully associated to the
hostapd but fail to get added in the driver/firmware, will not
work. In such cases, hostapd should deauth and disconnect such
stations. In such scenario, hostapd should disconnect the STAs.

a7fd39bb5d P2P: Cleanup AP callbacks when removing the group
Clear the P2P GO callback parameters when removing the group to avoid
using these for non-P2P AP mode.

This is a fix for the bug I found in the following scenario:

A) p2p_group_add
A) p2p_group_remove wlan0
A) add_n
A) set_n 0 ssid "testap"
A) set_n 0 key_mgmt NONE
A) set_n 0 mode 2
A) set_n 0 frequency 2412
A) enable_n 0

B) try connect to testap

Authentication request will be always rejected because of
HOSTAPD_ACL_REJECT and not cleaned callbacks when group removed.

fd8e4fda50 EAPOL auth: Disconnect after IEEE 802.1X failure
The EAPOL authenticator was previously forcing disconnection in the WPS
use case. However, this can be benefitial operation with any IEEE 802.1X
authentication mechanism and need not be limited to WPS. This helps some
use cases like EAP-FAST where provisioning may require two
authentication runs if the authentication server does not allow the PAC
provisioning step to be used for normal data connection. While the
station would be free to decide to re-associate in such a case, not all
stations do and as such, it helps if the AP does that instead of leaving
the association up with EAPOL state machine in HELD state for 60
seconds.

88dc899a1b EAP-FAST: Allow unprotected EAP-Failure in provisioning case
While EAP-FAST uses protected success notification, RFC 5422, Section
3.5 points out a possibility of EAP-Failure being sent out even after
protected success notification in case of provisioning. Change the
EAP-FAST peer implementation to accept that exception to the protected
success notification. This allows the station to re-connect more quickly
to complete EAP-FAST connection in the case the server rejects the
initial attempt by only allowing it to use to provision a new PAC.

Flush the other entries based on network_ctx matches to get rid of the
OKC entries. These entries can then be re-creating using OKC with the

1473f95e98 AP: Use QoS nullfunc for connection poll
When polling a station that has been inactive for a while, hostapd currently
always uses a null data frame. This is a bit strange with uAPSD clients
(though it seems to mostly work) since the EOSP bit can never be set in a
non-QoS frame. Make hostapd use QoS null data frames for probing when the
station is a QoS STA.
