b39a05913a Simplify Timeout Interval element parsing
Remove the length field from struct ieee802_11_elems since the only
allowed element length is five and that is checked by the parser.

ae7a42bde2 FT: Check FT, MD, and Timeout Interval length in the parser
All the existing users of these elements were already validating the
element length. However, it is clearer to validate this already at the
parser for extra layer of protection for any future changes.

05e46a944a Ignore too long SSID element value in parser
The SSID element is defined to have a valid length range of 0-32. While
this length was supposed to validated by the users of the element
parser, there are not really any valid cases where the maximum length of
32 octet SSID would be exceeded and as such, the parser itself can
enforce the limit as an additional protection.

e7d0e97bdb hostapd: Add vendor specific VHT extension for the 2.4 GHz band
This allows vendor specific information element to be used to advertise
support for VHT on 2.4 GHz band. In practice, this is used to enable use
of 256 QAM rates (VHT-MCS 8 and 9) on 2.4 GHz band.

This functionality is disabled by default, but can be enabled with
vendor_vht=1 parameter in hostapd.conf if the driver advertises support
for VHT on either 2.4 or 5 GHz bands.

533630625d Add generic operating class and channel to frequency function
ieee80211_chan_to_freq() is a generic function that replaces and extends
the previous P2P-specific p2p_channel_to_freq(). The new function
supports both the global operating class table as well as the additional
US, EU, JP, and CN operating class tables.

3a88914d8e Remove unused information element parsing data
These information elements are not really used anywhere in hostapd or
wpa_supplicant nor is there any plan to use them. As such, there is no
need to keep the code here either, so save couple of bytes here.

56f5af489c Interworking: Add support for QoS Mapping functionality for the STA

Map if QoS Map Set elements is received from the AP either in
(Re)Association Response or QoS Map Configure frame.

This commit adds support for receiving the frames with nl80211 drivers,

This commit adds control interface commands and internal storage of
Wi-Fi Display related configuration. In addition, WFD IE is now added
to various P2P frames, Probe Request/Response, and (Re)Association
Request/Response frames. WFD subelements from peers are stored in the
P2P peer table.

Following control interface commands are now available:
SET wifi_display <0/1>
GET wifi_display
WFD_SUBELEM_SET <subelem> [hexdump of length+body]

information to the (Re)Association Response frame from the AP and parse

timer to handle periodic transmission of the keep-alive frame. The
actual request for the driver to transmit a frame is not yet
implemented.

babfbf15cc FT: Add RIC Request generation and validation (but not processing)
This adds first part of FT resource request as part of Reassocition
Request frame (i.e., FT Protocol, not FT Resource Request Protocol).
wpa_supplicant can generate a test resource request when driver_test.c
is used with internal MLME code and hostapd can verify the FTIE MIC
properly with the included RIC Request.

The actual RIC Request IEs are not processed yet and hostapd does not
yet reply with RIC Response (nor would wpa_supplicant be able to
validate the FTIE MIC for a frame with RIC Response).

adddffd129 Fixed MFP Association Comeback mechanism to use Timeout Interval IE
The separate Association Comeback Time IE was removed from IEEE 802.11w
and the Timeout Interval IE (from IEEE 802.11r) is used instead. The
editing on this is still somewhat incomplete in IEEE 802.11w/D7.0, but
still, the use of Timeout Interval IE is the expected mechanism.

ad08c3633c Added preliminary Wi-Fi Protected Setup (WPS) implementation
This adds WPS support for both hostapd and wpa_supplicant. Both programs
can be configured to act as WPS Enrollee and Registrar. Both PBC and PIN
methods are supported.

Currently, hostapd has more complete configuration option for WPS
parameters and wpa_supplicant configuration style will likely change in
the future. External Registrars are not yet supported in hostapd or
wpa_supplicant. While wpa_supplicant has initial support for acting as
an Registrar to configure an AP, this is still using number of hardcoded
parameters which will need to be made configurable for proper operation.
