Antonio reported that RSN IBSS failed to work.
We traced it down to a GTK failure, and he then
bisected it to commit bdffdc5ddb:
"AP: Reorder WPA/Beacon initialization".
The reason this commit broke it is that the state
machine's GInit variable is never set to false as
wpa_init_keys() never gets called, and thus new
keys are generated every time the state machine
executes.
Fix this by calling wpa_init_keys() when the new
group has been initialised.

Previously, the WPS scans could have been done in associated state if we
happened to be associated when the request to use WPS was received. This
can slow down scanning and end up in unexpected state if no WPS
association is tried. Avoid these issues by disconnecting when WPS
search is started.

Convert core wpa_supplicant code to use u64 instead of void * for the
P2P service discovery reference. Use uintptr_t in type casts in
p2p_supplicant.c to handle the conversion without warnings.
Note: This needs to be revisited for 128-bit CPU where sizeof(void *)
could be larger than sizeof(u64).

A Pending Provision Discovery Request was sent in SEARCH phase after a

This allows per-device PSK to be configured for WPA-Personal using a
RADIUS authentication server. This uses RADIUS-based MAC address ACL
(macaddr_acl=2), i.e., Access-Request uses the MAC address of the
station as the User-Name and User-Password. The WPA passphrase is
returned in Tunnel-Password attribute in Access-Accept. This
functionality can be enabled with the new hostapd.conf parameter,
wpa_psk_radius.

WPS overlap detection can detect false overlap if a P2P peer
changes UUID while authentication is ongoing. Changing UUID
is of course wrong but this is what some popular devices do
so we need to work around it in order to keep compatibility
with these devices. There already is a mechanism in WPS
registrar to skip overlap detection if P2P addresses of two
sessions match but it wasn't really triggered because the
address wasn't filled in in the caller function.
Let's fill in this address and also clean up WPS PBC sessions
on WSC process completion if UUID was changed.

If a P2P group network block is removed for any reason (e.g., wps_cancel

formation timeout and indicate failure immediately. Previously, this
type of operations could end up leaving the timeout running and result
in somewhat unexpected group formation failure events later.

Testing code can now be enabled in the hostapd RADIUS server to dump
each derived MSK into a text file (e.g., to be used as an input to
wlantest). This functionality is not included in the default build
and can be enabled by adding the following line to hostapd/.config:
CFLAGS += -DCONFIG_RADIUS_TEST
The MSK dump file is specified with dump_msk_file parameter in
hostapd.conf (path to the dump file). If this variable is not set,
MSK dump mechanism is not enabled at run time.

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

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.

When using authentication retry within driver_nl80211.c, a failure on the

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 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
