0a40ec6a90 Always clear EAP altAccept and altReject variables on new association
Previously, this was only done when the new connection is using
WPA-Personal. However, it looks like it was possible to trigger an
infinite busy loop if altAccept or altReject were left set to true and
an EAPOL frame is received (eapolEap is set to true). Clearing altAccept
and altReject for each association prevents this loop from happening in
the beginning of the next association.

351f09a221 WPS: Added support for fragmented WPS IE in Beacon and Probe Response
Fragment WPS IE if needed to fit into the IE length limits in hostapd
and Reassemble WPS IE data from multiple IEs in wpa_supplicant.

In addition, moved WPS code from events.c into wps_supplicant.c to clean
up module interfaces.

fcc60db4eb WPS: Added wpa_supplicant ctrl_iface commands to start WPS processing
New control interface commands WPS_PBC, WPS_PIN, and WPS_REG can be used
to start WPS processing. These add and select the WPS network block into
the configuration temporarily, i.e., there is no need to add the WPS
network block manually anymore.

c0d041d9a7 WPS: Moved ProbeReq/AssocReq WPS IE building into wps_common.c
This code and the related attributes are not specific to Enrollee

398cfbf6be WPS: Moved mac_addr and uuid configuration into wps_context

116654ce24 WPS: Moved wps_context initialization into wps_supplicant.c
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.

bcbbc7af45 WPS: Merged two cred_cb variables into the same one
Previously, wpa_supplicant as Enrollee case was handled using a
different callback function pointer. However, now that the wps_context
structure is allocated for all cases, the same variable can be used in
all cases.

as WPS is concerned.

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.

1ac2d4a9ee Fixed canceling of PMKSA caching with driver generated RSN IE
It looks like some Windows NDIS drivers (e.g., Intel) do not clear the
PMKID list even when wpa_supplicant explicitly sets the list to be
empty. In such a case, the driver ends up trying to use PMKSA caching
with the AP and wpa_supplicant may not have the PMK that would be needed
to complete 4-way handshake.

RSN processing already had some code for aborting PMKSA caching by
sending EAPOL-Start. However, this was not triggered in this particular
case where the driver generates the RSN IE. With this change, this case
is included, too, and the failed PMKSA caching attempt is cleanly
canceled and wpa_supplicant can fall back to full EAP authentication.

8038591be2 wpa_gui: Add a PNG version of the tray icon for Windows binary build
It looks like Qt does not support SVG format by default on Windows and
it was not trivial to add the plugin into the build, so for now, build a
16x16 PNG icon file for Windows binary to avoid showing an invisible

98842d51ec Separate OpenSSL engine configuration for Phase 2
I fixed the engine issue in phase2 of EAP-TTLS. The problem was that you
only defined one engine variable, which was read already in phase1. I
defined some new variables:

engine2
engine2_id
pin2

and added support to read those in phase2 wheres all the engine
variables without number are only read in phase1. That solved it and I
am now able to use an engine also in EAP-TTLS phase2.

e519314ee9 Add RoboSwitch driver interface for wpa_supplicant
Find attached the patch that creates a new driver: roboswitch. This
driver adds support for wired authentication with a Broadcom
RoboSwitch chipset. For example it is now possible to do wired
authentication with a Linksys WRT54G router running OpenWRT.

LIMITATIONS
- At the moment the driver does not support the BCM5365 series (though
adding it requires just some register tweaks).
- The driver is also limited to Linux (this is a far more technical
restriction).
- In order to compile against a 2.4 series you need to edit
include/linux/mii.h and change all references to "u16" in "__u16". I
have submitted a patch upstream that will fix this in a future version
of the 2.4 kernel. [These modifications (and more) are now included in
the kernel source and can be found in versions 2.4.37-rc2 and up.]

USAGE
- Usage is similar to the wired driver. Choose the interfacename of
the vlan that contains your desired authentication port on the router.
This name must be formatted as <interface>.<vlan>, which is the
default on all systems I know.

cd35db9fef Updated userspace MLME instructions for current mac80211
Remove the old code from driver_wext.c since the private ioctl interface is
never going to be used with mac80211. driver_nl80211.c has an
implementation than can be used with mac80211 (with two external patches to
enable userspace MLME configuration are still required, though).

46690a3b9b Added an optional mitigation mechanism for certain attacks against TKIP by
delaying Michael MIC error reports by a random amount of time between 0 and
60 seconds if multiple Michael MIC failures are detected with the same PTK
(i.e., the Authenticator does not rekey PTK on first failure report). This
is disabled by default and can be enabled with a build option
CONFIG_DELAYED_MIC_ERROR_REPORT=y in .config.

This may help in making a chopchop attack take much longer time by forcing
the attacker to wait 60 seconds before knowing whether a modified frame
resulted in a MIC failure.

581a8cde77 Added support for enforcing frequent PTK rekeying
Added a new configuration option, wpa_ptk_rekey, that can be used to
enforce frequent PTK rekeying, e.g., to mitigate some attacks against TKIP
deficiencies. This can be set either by the Authenticator (to initiate
periodic 4-way handshake to rekey PTK) or by the Supplicant (to request
Authenticator to rekey PTK).

With both wpa_ptk_rekey and wpa_group_rekey (in hostapd) set to 600, TKIP
keys will not be used for more than 10 minutes which may make some attacks
against TKIP more difficult to implement.
