2aaeedfa07 bridge: Give bridge name in per-bss configuration
Currently, when different BSS using different tagged vlan
interfaces, they are forced to share the bridge brvlan#,
which is not desirable.

This patch fixes this by making the bridge name configurable.

4331263b73 Fix session timeout after ANQP dummy STA entry with SME-in-driver
Upon association, disable the timer that removes the dummy STA. This
timer caused the STA that associates within 5 seconds of doing an ANQP
query to disassociate, thinking it's a dummy STA. Similar call was
already there for the SME/MLME-in-hostapd case in handle_auth(), but the
SME-in-driver case was not previously addressed.

aa20e1a1fb Remove CONFIG_NO_WPA2 build parameter
There is not much use for enabling WPA without WPA2 nowadays since most

add9b7a46a nl80211: Ignore deauth/disassoc event from old AP
It looks like cfg80211 can deliver a deauth/disassoc event during some
roaming cases while we are already in progress with a new

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.

4033935dd9 Fix OKC-based PMKSA cache entry clearing
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.

2cadc8e1e5 TDLS: Retry TDLS Setup Response more quickly
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.

7ca902b53e Make vlan_file optional if dynamic_vlan is used
My APs generate their configuration on their own using a different
number of (vlan-enabled) bss. Currently, all my vlan_file files consist
of a single line: the wildcard line. Configuration file generation would
be easier, if the hostapd configuration file would not depend on those
simple vlan_file files.

This patch removes the need for those one-line files by using the
<device>.<vlan> naming scheme if no vlan_file is given (or that file is
empty). This should not break any existing setup, as using dynamic_vlan
with no vlan configured does not make sense anyway.

7800d45c71 P2P: Set P2P_DEV_PEER_WAITING_RESPONSE from TX status callback
Commit fb8984fd6f added a mechanism to
skip the Listen state when the peer is expected to be waiting for us to
initiate a new GO Negotiation. However, this flag was set when building
the GO Negotiation Response frame with status 1 regardless of whether we
managed to send that frame or peer receive it. This could result in GO
Negotiation failures in cases where the peer did not receive the
response and Listen channels of the devices were different. Fix this by
setting the flag only after TX status indicating success has been
received.

bb0122f3e8 SAE: Add forgotten commit element validation step for FFC groups
The peer commit element needs to be validated to pass one of the steps
listed in IEEE 802.11, 11.3.5.4:
scalar-op(r, ELEMENT) = 1 modulo p

Similar step was present for ECC groups, but was missing for FFC groups.
This is needed to avoid dictionary attacks.

3a2a7c3da6 P2P: Fix regression in GO Negotiation
Commit fb8984fd6f cleared wps_method to
WPS_NOT_READY in p2p_stop_find_for_freq() as an attempt to clear
authorization when a group formation is cancelled. However, this code
path is hit also in cases where the user did not actually cancel
anything (e.g., from p2p_process_go_neg_req()). As such, it is not fine
to clear wps_method here even if it could be proper for some cases. For
now, revert that part to avoid regressions and consider clearing
wps_method on cancel separately.

fb8984fd6f P2P: Skip Listen phase when peer is expected to be waiting
In case we have replied to a peer's GO Negotiation Request frame with a
GO Negotiation Response frame using status code
info-currently-unavailable (1), the peer is likely going to wait for us
to initiate GO Negotiation on its Listen channel. We were previously
using alternativing send-GO-Neg-Req and Listen phase when providing that
response after the user had authorized the connection. However, the
Listen phase here is unnecessary in this case and will make the
connection take longer time to go through. Skip the Listen phase and
make the wait-for-GO-Neg-Resp timeout random between 100 and 200 ms to
avoid getting in sync with the peer. In practice, this will make us
retry GO Negotiation Request frames more frequently and remain on the
peer's Listen channel for most of the time when initiating GO
Negotiation after status=1 response.

8cee87ab13 P2P: Only schedule a single p2p_go_neg_start timeout at a time
It is possible for the driver to indicate multiple Probe Request frames
that would be processed in a single loop. If those frames happen to be
from a peer which with we are trying to start GO Negotiation, multiple
timeouts to start GO Negotiation (p2p_go_neg_start) could end up being
scheduled. This would result in confusing burst of multiple GO
Negotiation Request frames being sent once the RX loop finally
concludes. Avoid this by scheduling only a single eloop timeout to
trigger GO Negotiation regardless of how many Probe Request frames from
the peer is received. In addition, make sure this timeout gets canceled
in p2p_deinit().

The device that is selected as the GO shall incode P2P Group ID
attribute in GO Negotiation Response/Confirm message. Previously we did
not reject a message without that attribute since it was possible to
continue operations even without knowing the SSID. However, this can
potentially result in confusing results since missing P2P Group ID
attribute can be a sign of conflicting GO role determination (both
devices assuming the peer is the GO). To get clearer end result for the
GO Negotiation, reject this as a fatal error. In addition, stop GO
Negotiation if GO Negotiation Confirm indicates non-zero status since
that is also a fatal error.

003c45804f P2P: Assign GO tie breaker bit at the same time with dialog token
Commit 624b4d5a64 changed GO Negotiation
to use the same Dialog Token value for all retransmissions of the GO
Negotiation Request within the same session. However, it did leave the
tie breaker bit changing for each frame. While this should not have
caused issues for most cases, it looks like there are possible sequences
where the peer may end up replying to two GO Negotiation Request frames
with different tie breaker values. If in such a case the different GO
Negotiation Response frames are used at each device, GO role
determination may result in conflicting results when same GO intent is
used.

Fix this by assigning the tie breaker value at the same time with the
dialog token (i.e., when processing the p2p_connect command instead of
for each transmitted GO Negotiation Request frame) to avoid issues with
GO selection.
