To support Android the kernel may have a "p2p0" netdev for a P2P Device
even though this isn't very useful, but Android requires a netdev. To
support this in the supplicant, if the interface mode is P2P_DEVICE,
re-set it to the same instead of STATION mode.
Note that this is only possible with a kernel that creates a
netdev for the P2P Device wdev.

Add wdev_id to i802_bss. wdev_id_set indicates whether this id is
available. Use wdev_id if assigned, instead of ifindex. Use wdev_id for
events that come from the kernel to identify the relevant interface.
This commit does not assign wdev_id value for the BSS yet, i.e., this is
only preparation for the value to be used in a future commit.

Sometimes an interface name that cannot be resolved is given to the

Currently, hostapd_get_vlan_id_ifname() is used to determine if a given
vlan is valid *and* to actually determine the interface. This leads to
wpa_set_keys() sometimes setting the key on the wildcard interface name,
which does not make sense.
This patch therefore adds hostapd_vlan_id_valid() and makes
hostapd_get_vlan_id_ifname() not return a wildcard interface.

Currently, struct hostapd_vlan is a per-BSS data structure which
also contains informations about whether to remove the bridge
or clear wlan / tagged-vlan interface from the bridge.
In a multi-interface multi-BSS setup, this can lead to the following
race condition:
1. wlan0 creates VLAN A, sets DVLAN_CLEAN_BR and DVLAN_CLEAN_VLAN_PORT
2. wlan1 creates VLAN A, does not set DVLAN_CLEAN_BR and
DVLAN_CLEAN_VLAN_PORT as already there
3. wlan0 removes VLAN A, removes tagged-interface from the bridge
but not the bridge.
Now wlan1 VLAN A is unusable due to the missing uplink.
4. wlan1 removes VLAN A, does not cleanup
Solution:
This requires an inter-BSS inter-interface data structure to track the
bridge / bridge port usage within hostapd. This data structure could
also be used to track any other device-has-been-created-by-hostapd
information or when regarding interface freeing.

Currently by default, all BSS share the bridge brvlan%d.
While this is sane when no tagged-interface is given, this
is insane when different tagged interfaces are given, as
it would result in bridging those tagged interfaces.
This patch therefore uses br%s%d with %s=tagged_interface
and %d=VLAN ID as bridge name when a tagged-interface is given.
Signed-hostap: Michael Braun <michael-dev@fami-braun.de>
Currently, when different BSS using different tagged vlan

It looks like cfg80211 can deliver a deauth/disassoc event during some
roaming cases while we are already in progress with a new
authentication/association. This happens at least with FT protocol.
Avoid issues with such disconnection event resulting in core
wpa_supplicant stopping the new connection attempt by tracking
auth/assoc BSSID more carefully within driver_nl80211.c and filtering
out events that do not apply for the current AP.

Commit c3fea27274 added a call to clear
all other PMKSA cache entries for the same network if the PMKSA cache
entry of the current AP changed. This was needed to fix OKC cases since
the other APs would likely use the new PMK in the future. However, this
ended up clearing entries in cases where that is not desired and this
resulted in needing additional full EAP authentication with networks
that did not support OKC if wpa_supplicant was configured to try to use
it.
Make PMKSA cache entry flushing more limited so that the other entries
are removed only if they used the old PMK that was replaced for the
current AP and only if that PMK had previously been used successfully
(i.e., opportunistic flag was already cleared back to 0 in
wpa_supplicant_key_neg_complete()). This is still enough to fix the
issue described in that older commit while not causing problems for
standard PMKSA caching operations even if OKC is enabled in
wpa_supplicant configuration.

TDLS responder STA used to retransmit the TDLS Setup Response after 5
seconds if the TDLS Setup Confirm is not received. The initiator would
have enabled the TDLS link and started transmitting the data to the peer
on the TDLS link after transmitting the TDLS Setup Confirm frame. If the
TDLS Setup Confirm frame is not received by the receiver, the
transmissions from the initiator on the direct link would get failed for
the TDLS link not getting enabled on the receiver. This commit reduces
the data delivery failure duration by shortening the retry time of the
TDLS Setup Response frames. The retry limit of the TDLS Response frame
also is increased to ensure that the peer does not miss the frames in
the reduced time period.

Commit 97279d8d1a started filtering MLME
frame events based on Address 1 (destination) field. This works fine for

such case is deauthentication or disassociation triggered by something

for frames where either Address 1 or 2 (transmitter) matches the
