This is a rewrite of Ben Greear's patch, making the
nl80211 code use just a single multicast event socket.
Signed-hostap: Johannes Berg <johannes.berg@intel.com>
When running AP mode, we need to receive beacons over overlapping BSSes
to handle protection. Use the new nl80211 command for this. As the
command works per wiphy (and we don't want to receive the Beacon frames
multiple times) add an abstraction that keeps track of per-wiphy data.

These events are necessary to send deauth frames to
stations sending spurious data frames. Subscribe to
them on the per-BSS event socket.
Signed-hostap: Johannes Berg <johannes.berg@intel.com>
To achieve this, multiple things are needed:
1) since hostapd needs to handle *all* action frames,
make the normal registration only when in a non-AP
mode, to be able to do this use the new socket
2) store the frequency in each BSS to be able to give
the right frequency to nl80211's mgmt-tx operation
3) make TX status processing reject non-matched cookie
only in non-AP mode
The whole thing depends on having station-poll support
in the kernel. That's currently a good indicator since
the kernel patches are added together.

Fix start of reauthentication after failed authentication with

When using authentication retry within driver_nl80211.c, a failure on the
second attempt has to be indicated with a driver event since the return
code from wpa_driver_nl80211_authenticate() is not actually delivered to
the core code in that case.

The wpa_state needs to be dropped back to DISCONNECTED to allow scan
results to trigger a new authentication attempt.
Signed-hostap: Jouni Malinen <j@w1.fi>
If the AP disconnects us with a reason code that indicates that it has
dropped the association, but could allow us to connect again, try to
reconnect to the same BSS without going through the full scan. This can
save quite a bit of time in some common use cases, e.g., when inactivity
timeout is used on the AP (and especially, when waking up from suspend
which has likely triggered some timeout on the AP).

cfg80211 rejects NL80211_CMD_AUTHENTICATE with ENOENT if the BSS entry
for the target BSS is not available. This can happen if the cfg80211
entry has expired before wpa_supplicant entry (e.g., during a suspend).
To recover from this quickly, run a single channel scan to get the
cfg80211 entry back and then retry authentication command again. This
is handled within driver_nl80211.c to keep the core wpa_supplicant
implementation cleaner.

The wpa_state needs to be dropped back to DISCONNECTED to allow scan
results to trigger a new authentication attempt. In addition, we can use
wpas_connection_failed() instead of requesting a scan after a fixed time
to make this error case more consistent with other similar error paths
in sme.c.

The pseudonym is a temporary identity, but is no one-time identifier (like
the fast re-authentication identity). Thus, do not forget it if the server
does not include it in every challenge. There are servers that include the
pseudonym identity only at full-auth. [Bug 424]
Make sure sign extension does not end up getting used here by
explicitly type casting the variables to correct size.

Storing the frequency in the bss struct allows using it for frame
commands in AP mode and not relying on the driver struct as much, which

This will allow getting TX status for EAPOL frames

Previously, sm->start_reauth was set to TRUE in SUCCESS2 state to force
reauthentication to start with EAP identity request. This works fine for
the case of EAP success through the AAA passthrough authentication, but
is not enough to handle passthrough authentication failure. sm->identity
is set in that case and getDecision would return PASSTHROUGH instead of
CONTINUE (to Identity method).

I have a test case where I remove and insert another network adapter
between two connections to AP. The interface get the same interface name
but switches macadresses between the connections. When running WPA2 I
got a failure in EAPOL negotiation and found out that the reason for
this was that the supplicant did not update the MAC address in the
correct place.

When using wpa_supplicant AP mode, WPS support is enabled by default for
WPA/WPA2-Personal. Change this to enforce the WPS2 rules on not allowing
WPS to be used with WPA/TKIP-only configuration (i.e., at minimum, mixed
mode with WPA/TKIP and WPA2/CCMP has to be used for WPS to be enabled).

A disconnection event from the driver may end up getting delivered at a
time when wpa_supplicant is not even trying to connect (e.g., during a
scan that was already started after WPS provisioning step). In such a
case, there is not much point calling wpas_connection_failed() and
skipping this avoids confusing attempts of re-starting scanning while
the previous scan is still in progress.

The show_group_started variable could be left to 1 based on an earlier
failed attempt to start P2P client operation. This can result in
unexpected P2P-GROUP-STARTED event when a GO is started without group
formation (e.g., re-invoke a persistent group or start an autonomous
GO). Avoid this by explicitly clearing show_group_start when setting up
the GO.

When hostapd controls multiple radios, WPS operations are started on
all interfaces. However, when the provisioning run had been completed
successfully, actiove WPS mode was stopped only a single interface. Fix
this to iterate through all interfaces so that this is handled

Commit 628d54639a introduced number
of new WPS related ctrl_iface messages to hostapd. Some of these
were for ER events which do not make any sense to hostapd that
cannot operate as an ER. The WPS_EV_ER_SET_SELECTED_REGISTRAR one
from wps_registrar_sel_registrar_changed_event() was especially
problematic since it can cause wpa_supplicant ER code segfault due
to missing event data.
Revert all the ER specific changes from commit
628d54639a to get rid of the segfault
and undesired extra code in hostapd.
