6e6909a97e FIPS: Remove MD5 from the CONFIG_FIPS=y build
When CONFIG_FIPS=y is used, do not include MD5 in the build and disable
EAPOL-Key frames that use MD5 (WPA/TKIP and dynamic WEP with IEEE
802.1X).

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
from an external storage.

Following example can be used for developer testing:

ext_password_backend=test:pw1=password|pw2=testing

network={
    key_mgmt=WPA-EAP
    eap=TTLS
    identity="user"
    password=ext:pw1
    ca_cert="ca.pem"
    phase2="auth=PAP"
}

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.

the received server certificate chain to be written to the specified

ade74830b4 Add dbus signal for information about server certification
In general, this patch attemps to extend commit
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
user accepts it, is remembered and passed to subject_match config
for any future authentication.

7992b07f6a Remove unnecessary SUBDIRS loops from src/*/Makefile
There are no subdirectories in any of these directories or plans
for adding ones. As such, there is no point in running the loop
that does not do anything and can cause problems with some shells.

90973fb2fd Remove src/common from default header file path
This makes it clearer which files are including header from src/common.
Some of these cases should probably be cleaned up in the future not to
do that.

In addition, src/common/nl80211_copy.h and wireless_copy.h were moved
into src/drivers since they are only used by driver wrappers and do not
need to live in src/common.

8ef1683115 Remove rc4() wrapper
This is not really of that much use since rc4_skip() can be used as
easily. In addition, rc4 has caused some symbol conflicts in the past,
so it is easier to live without that as an exported symbol.

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.

The wps_context data is now managed at wpa_supplicant, not EAP-WSC. This
makes wpa_supplicant design for WPS match with hostapd one and also
makes it easier configure whatever parameters and callbacks are needed
for WPS.

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.
