22a299ee9d Improve EAPOL-Key handshake stability with retransmitted frames
Accept response to any pending request, not just the last one. This
gives the Supplicant more time to reply since hostapd will now allow up
to three seconds for the reply to the first EAPOL-Key frame transmission
(and two seconds for the first retry and one second for the last) while
the previous version invalidated any old request immediately when
sending a retransmitted frame.

If the Supplicant replies to more than one request, only the first reply
to arrive at the Authenticator will be processed. As far as the
Supplicant is concerned, this behavior does not differ from the previous
one except for being less likely to cause unneeded retransmissions of
EAPOL-Key frames.

This can help in cases where power saving is used when the group key is
rekeyed or when there is excessive traffic on the channel that can delay
(or drop) EAPOL-Key frames.

e33bbd8f4d driver_test: Optional support for using UDP socket
driver_test can now be used either over UNIX domain socket or UDP
socket. This makes it possible to run the test over network and makes it
easier to port driver_test to Windows.

hostapd configuration: test_socket=UDP:<listen port>
wpa_supplicant configuration: driver_param=test_udp=<dst IP addr>:<port>

205a372b2d Added libnl 2.0 compatibility code (CONFIG_LIBNL20=y in .config needed)
Unfortunately, at least the current libnl git snapshot changes the API
in backwards incompatible way and in a way that makes it difficult to
to allow building against the latest libnl code.

This makes it easier to build the packages and allows all new features
to be built into the binary regardless of which kernel is currently
used.

bb9f45e0bb nl80211: Remove the debug print from data frame processing
This is currently happening way too frequently (mac80211 monitor
interface sends TX info for every frame) and the end result makes it
difficult to read hostapd debug log if there is large amount of data
traffic.

4a7b9f885f Fixed WEP authentication (both Open System and Shared Key) with mac80211
Only one of the authentication frame types is encrypted. In order for
static WEP encryption to work properly (i.e., to not encrypt the frame),
we need to tell mac80211 about the frames that must not be encrypted.

f07688e37d nl80211: Generate 802.11b mode based on 802.11g information
If the phy info from nl80211 does not include 802.11b mode, generate
that mode based on 802.11g information. This allows hw_mode=b to be used
with drivers that support 2.4 GHz band.

8c37556cd1 Add a starting point for EAP-AKA' (draft-arkko-eap-aka-kdf-10)
This is just making an as-is copy of EAP-AKA server and peer
implementation into a new file and by using the different EAP method
type that is allocated for EAP-AKA' (50). None of the other differences
between EAP-AKA and EAP-AKA' are not yet included.

It is likely that once EAP-AKA' implementation is done and is found to
work correctly, large part of the EAP-AKA and EAP-AKA' code will be
shared. However, it is not reasonable to destabilize EAP-AKA
implementation at this point before it is clearer what the final
differences will be.

08bec36178 WPS: Added support for wildcard PINs that work with any UUID-E
Since the Registrar may not yet know the UUID-E when a new PIN is
entered, use of a wildcard PIN that works with any UUID-E can be useful.
Such a PIN will be bound to the first Enrollee trying to use it and it
will be invalidated after the first use.

a8d05fca5f Clear various flags on re-association to allow key_mgmt changes
If a STA reassociates and changes key_mgmt (e.g., from WPA-PSK to WPS),
hostapd needs to reset some of the existing STA and WPA state machine
variables to allow correct processing for the new association.

eb76b7e3ff WPS: Parse Request Type from WPS IE in (Re)AssocReq and derive mgmt keys
WPS IE is now passed from hostapd association processing into EAP-WSC
and WPS processing. Request Type attribute is parsed from this
information and if the request is for a WLAN Manager Registrar,
additional management keys are derived (to be used with UPnP).

merged into wireless-testing. If that change is not present, the old
mechanism (WEXT) will be used instead.

ffbcf648ed Change HT parameter configuration to use a single driver ops function
It is better to pass both HT Capabilities and HT Operation IEs in the
same function call since it may be easier for the driver wrappers to
handle the changes without having to wait for the other IE in the
wrapper code.

d6c9d4740b driver_nl80211: Added set_country() handler

"iw reg set <alpha2>" is not needed anymore when using hostapd.

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.

2fc98d02c1 Simplified RADIUS accounting id usage
Changed accounting_sta_start() to call accounting_sta_get_id()
internally in accounting.c so that external callers do not need to do
anything to allocate unique accounting id. When starting a new session,
a unique identifier is needed anyway, so no need to keep these
operations separate.

fe2c5241b5 Remove experimental non-AP STA code from hostapd
This was used to allow hostapd to associate as a non-AP STA to another
AP one the same channel while still acting as an AP with the Host AP
driver. This was very experimental and did not work with all firmware
versions. Nowadays, much better way of doing this is to use mac80211
virtual non-AP STA interface. As such, this experimental code can be
removed from hostapd to reduce the code size and make MLME code easier
to understand since it is now only handling AP functionality.

ddaa83ebeb Remove overly complex hostapd setup sequence with n+1 callbacks
This code was originally added as a mechanism to handle long waits
during channel selection and/or radar detection. It is not currently
really used and makes the setup sequence nearly impossible to
understand. Let's get rid of the unwanted complexity. This needs to be
redesigned if it is ever needed again.
