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.
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.
This cleans up the internal interface between different modules and is
the first step in getting wpa_supplicant design closer to hostapd as far
as WPS is concerned.
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.
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.
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
icon in the tray.
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.
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.
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).
Updated OpenSSL code for EAP-FAST to use an updated version of the
session ticket overriding API that was included into the upstream
OpenSSL 0.9.9 tree on 2008-11-15 (no additional OpenSSL patch is
needed with that version anymore).
GCC 4.4 cleaned up some more C++ headers. You always have to #include
headers directly and cannot rely for things to be included indirectly.

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.
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.
This may be needed if the AP does not disconnect in case of EAP-FAST
unauthenticated provisioning (EAP-Failure). Adding the local short timeout
will speed up the process in such a case by reducing the wait (which can
often be up to 60 seconds).
This allows identity (etc.) variables to be removed from configuration
which is different from setting them to an empty string. For example,
EAP-SIM and EAP-AKA can now be configured to use identity string generation
from SIM/USIM by clearing the identity string in wpa_gui.
Setting the value of the SET_NETWORK command to NULL (without quotation)
unsets the variable, i.e., removes it from configuration file. This is
needed to allow GUI programs to clear variables, e.g., identity for
EAP-AKA/SIM.
Allow application to be started in the system tray only when started with
the `-t' command line argument.

When the system tray icon is created, qApp's setQuitOnLastWindowClosed
property is set to false, therefore do _not_ ignore widget close events, or
else wpa_gui will refuse to exit when the window manager is logging out.
While at it, remove WpaGui::fileExit() and connect fileExitAction to
quit().

A bug just got reported as a result of this for mac80211 drivers.
https://bugzilla.redhat.com/show_bug.cgi?id=459399
The basic problem is that since taking the device down clears the keys
from the driver on many mac80211-based cards, and since the mode gets
set _after_ the keys have been set in the driver, the keys get cleared
on a mode switch and the resulting association is wrong. The report is
about ad-hoc mode specifically, but this could happen when switching
from adhoc back to managed mode.
