c60ba9f7ab Skip network disabling on expected EAP failure
Some EAP methods can go through a step that is expected to fail and as
such, should not trigger temporary network disabling when processing
EAP-Failure or deauthentication. EAP-WSC for WPS was already handled as
a special case, but similar behavior is needed for EAP-FAST with
unauthenticated provisioning.

a5d44ac083 EAP peer: Add framework for external SIM/USIM processing
The new configuration parameter external_sim=<0/1> can now be used to
configure wpa_supplicant to use external SIM/USIM processing (e.g., GSM
authentication for EAP-SIM or UMTS authentication for EAP-AKA). The
requests and responses for such operations are sent over the ctrl_iface
CTRL-REQ-SIM and CTRL-RSP-SIM commands similarly to the existing
password query mechanism.

Changes to the EAP methods to use this new mechanism will be added in
separate commits.

fa7ae9501b Add test code for fetching the last configured GTK
This can be useful for some test cases, so allow wpa_supplicant to be
built with special test functionality to expose the current (last
configured) GTK. This is disabled by default and can be enabled by
adding following line into .config:
CFLAGS += -DCONFIG_TESTING_GET_GTK

The GTK can then be fetched with "wpa_cli get gtk".

f11b72c3e9 TDLS: Move AID=1 workaround into driver_nl80211.c
The use of AID=1 for the nl80211 dummy STA case is specific to the
driver (cfg80211), so better move this into the driver wrapper instead
of generic TDLS implementation.

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.

delaying Michael MIC error reports by a random amount of time between 0 and

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

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.

entries.

3e2ad1b932 Fixed race condition between disassociation event and group key handshake
This avoids getting stuck in state where wpa_supplicant has canceled scans,
but the driver is actually in disassociated state. The previously used code
that controlled scan timeout from WPA module is not really needed anymore
(and has not been needed for past four years since authentication timeout
was separated from scan request timeout), so this can simply be removed to
resolved the race condition. As an extra bonus, this simplifies the
interface to WPA module.
