90ac1f9fc9 Allow more complex BSSID masks to be used for multi-BSSID
If every secondary BSS is configured with a pre-set BSSID, hostapd does
not enforce the BSSID mask requirements anymore, i.e., they are used
only if hostapd is responsible for generating MAC addresses for virtual
interfaces.

eb1f7446b5 Move DTIM period configuration into Beacon set operation
This is needed to make mac80211 work with multi-BSS configuration. The
previous design ended up setting DTIM period for secondary BSSes before
setting the Beacon and driver_nl80211.c was not really prepared for
that. Eventually, the Beacon configuration routines should be combined
into a single driver operation, but for now, just moving this call is
the simplest workaround.

86f4deb635 FT: Fix status code values to match with IEEE 802.11r-2007
It looks like couple of status code values were changed during the
802.11r draft process and these were not updated in source code yet.

f238cf9f42 FT: Add RIC Request processing and RIC Response generation
hostapd will now go through the RIC Request and process each RDIE. Only
WMM TSPEC requests are currently supported; all other request
descriptors will be declined.

RIC Response is written by hostapd and verified by wpa_supplicant (MIC
validation). wpa_supplicant does not yet have code to notify the driver
about the resource request results.

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).

143a4bf632 WPS: Add a workaround for static WEP with Windows network probe
Windows XP and Vista clients can get confused about EAP-Identity/Request
when they probe the network with EAPOL-Start. In such a case, they may
assume the network is using IEEE 802.1X and prompt user for a
certificate while the correct (non-WPS) behavior would be to ask for the
static WEP key. As a workaround, use Microsoft Provisioning IE to
advertise that legacy 802.1X is not supported.

This seems to make Windows ask for a static WEP key when adding a new
network, but at least Windows XP SP3 was still marking IEEE 802.1X
enabled for the network. Anyway, this is better than just leaving the
network configured with IEEE 802.1X and automatic WEP key distribution.

9e783041fa Add a workaround for EAP-FAST with Cisco AP local RADIUS server
When using the internal TLS implementation, EAP-FAST unauthenticated
provisioning ends up proposing multiple cipher suites. It looks like
Cisco AP (at least 350 and 1200 series) local authentication server does
not know how to search cipher suites from the list and seem to require
that the last entry in the list is the one that it wants to use.
However, TLS specification requires the list to be in the client
preference order. As a workaround, ass anon-DH AES-128-SHA1 again at the
end of the list to allow the Cisco code to find it.

This fixed EAP-FAST provisioning with the following IOS version:
Cisco IOS Software, C350 Software (C350-K9W7-M), Version 12.3(8)JEA3,
RELEASE SOFTWARE (fc2)

a14bda9d9d driver_ndis: Detect Native 802.11 drivers (NDIS 6, Vista)
This is just there very first step on being able to do something with
wireless LAN on Vista. There is some example code for requesting a scan,
but it does not work in its current form. Anyway, this adds a wpa_printf
noting that Native 802.11 drivers are not yet supported.

c472ef754d driver_ndis: Add PAE group address to the multicast address
This is done with wired interfaces to fix IEEE 802.1X authentication
when the authenticator uses the group address (which should be happening
with wired Ethernet authentication).

This allows wpa_supplicant to complete wired authentication successfully
on Vista with a NDIS 6 driver, but the change is likely needed for
Windows XP, too.

ed843aaa33 WMM-AC: Fix hostapd processing of ADDTS Request and add test code
Calculate the estimated medium time using integer variables since there
is no real need to use floating point arithmetics here. In addition,
make sure there is no division by zero regardless of how invalid the
request from the station is. Reject invalid parameters and refuse
requests that would take most of the bandwidth by themselves.

Add test code into wpa_supplicant mlme.c to allow WMM-AC negotiation to
be tested with driver_test.

e1ee6b600b WPS: Add support for NFC out-of-band mechanism
The new file wps_nfc.c and ndef.c implements NFC device independent
operation, wps_nfc_pn531.c implements NFC device dependent operation.

This patch is only for the following use case:
- Enrollee = wpa_supplicant
- Registrar = hostapd internal Registrar

Following NFC methods can be used:
- Enrollee PIN with NFC
- Registrar PIN with NFC
- unencrypted credential with NFC

Encrypted credentials are not supported.

Enrollee side operation:

Registrar side operation:

Example configuration.
CONFIG_WPS=y
CONFIG_WPS_NFC=y
CONFIG_WPS_NFC_PN531=y

I used NFC device "NXP PN531". The NFC device access method is
confidential, so I used outer library. Please download below files from

4.2.6 Add device using NFC Method with configuration token

5.1.9 Add to AP using NFC Method with password token
through internal registrar
(I used SONY AP instead of NXP AP.)

7cc1b6c900 WPS: Add a workaround for TKIP/CCMP mixed mode credentials
Many deployed APs do not handle negotiation of security parameters well
when both TKIP and CCMP (or both WPA and WPA2) are enabled. The most
common end result seems to be ending up with the least secure option..

As a workaround, check whether the AP advertises WPA2/CCMP in Beacon
frames and add those options for the credential if needed. This allows
the client to select the most secure configuration regardless of how
broken the AP's WPS implementation is as far as auth/encr type
negotiation is concerned.
