45f4a97a3a eap_proxy: Add mechanism for allowing EAP methods to be offloaded
In addition to the offload mechanism, the Android configuration and
makefiles are extended to allow this to be configured for the build by
dropping in platform specific configuration files and makefile without
having to modify any existing files.

86cf382b80 Fix EAPOL supplicant port authorization with PMKSA caching
The previous eapol_sm_notify_cached() implementation forced the port
to be authorized when receiving EAPOL-Key msg 1/4 that included a
matching PMKID in cases when PMKSA caching is used. This is too early
since the port should really be authorized only after the PTK has been
configured which is the case when PMKSA caching is not used.

Fix this by using the EAPOL supplicant PAE state machine to go through
the AUTHENTICATING and AUTHENTICATED states instead of forcing a jump
to AUTHENTICATED without performing full state machine steps. This can
be achieved simply by marking eapSuccess TRUE at least with the current
version of EAP and EAPOL state machines (the earlier commits in this
function seemed to indicate that this may have not been that easy in
the older versions due to the hacks needed here).

This addresses an issue with nl80211-based driver interface when the
driver depends on the STA Authorized flag being used to prevent
unprotected frames from being accepted (both TX and RX) prior to PTK
configuration.

e026159a8e EAP-SIM/AKA: Store pseudonym identity in configuration
Use the anonymous_identity field to store EAP-SIM/AKA pseudonym identity
so that this can be maintained between EAP sessions (e.g., after
wpa_supplicant restart) even if fast re-authentication data was cleared.

bf0d9ae40f Add explicit EAPOL-Key length validation in processKey()
These checks would not really be needed since eapol_sm_rx_eapol()
validates the length fields. Anyway, these makes it more obvious to
anyone reviewing the code that there are no integer underflow issues in
processKey().

0ebb23e340 EXT PW: Add support for password parameter from external storage
This allows the password parameter for EAP methods to be fetched

    eap=TTLS
    identity="user"
    password=ext:pw1

dd7fec1f29 wpa_supplicant: Report EAP connection progress to DBus
Send an "EAP" signal via the new DBus interface under various
conditions during EAP authentication:

  - During method selection (ACK and NAK)
  - During certificate verification
  - While sending and receiving TLS alert messages
  - EAP success and failure messages

This provides DBus callers a number of new tools:

  - The ability to probe an AP for available EAP methods
    (given an identity).
  - The ability to identify why the remote certificate was
    not verified.
  - The ability to identify why the remote peer refused
    a TLS connection.

d033694ac5 Clear EAPOL authWhile and heldWhile values when port is disabled
IEEE Std 802.1X-2004 does not clear authWhile and heldWhile in this
case, but doing so allows the timer tick to be stopped more quickly when
the port is not enabled. Since these variables are used only within HELD
and RECEIVE states, clearing them on initialization does not change
actual state machine behavior. This reduces some unnecessary operations
in port disabled state and cleans up the wpa_supplicant debug log after
disconnection.

9ef1aaae24 Use an enum for EAP SM requests
Control requests will be extended for non-EAP uses later, so it makes
sense to have them be generic. Furthermore, having them defined as an
enum is easier for processing internally, and more generic for control
interfaces that may not use field names. The public ctrl_req_type /
field_name conversion function will be used later by the D-Bus control
interface too.

00468b4650 with dbus support.

This can be used by dbus client to implement subject match text
entry with preset value probed from server. This preset value, if

into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.

b414900a90 Reduce latency on starting WPS negotiation (TX EAPOL-Start earlier)
Reduce startWhen from 3 to 1 second if WPS is included in the build.
While this is done regardless of runtime WPS configuration, it is fine
to use a smaller value here in general. This cuts two seconds out from
WPS negotiation if the driver does not support addition of WPS IE into
the (Re)Association Request frame.

b385188de3 Add an EAPOL payload length workaround for a WPS implementation
Buffalo WHR-G125 Ver.1.47 seems to send EAP-WPS packets with too short
EAPOL header length field (14 octets regardless of EAP frame length).
This is fixed in firmware Ver.1.49, but the broken version is included
in many deployed APs. As a workaround, fix the EAPOL header based on the
correct length in the EAP packet. This workaround can be disabled with
eap_workaround=0 option in the network configuration.

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.
