If we discover a P2P peer based on a Beacon frame from the GO role, we
do not get information about the supported configuration methods. This
can result in issues if the P2P managing entity above wpa_supplicant is
not prepared to handling config_methods=0x0. To avoid this, postpone
reporting of the P2P-DEVICE-FOUND event when this happens on one of the
social channels. It would be good to be able to this on all channels,
but that could result in issues of never indicating the event for a peer
that is operating a GO on a channel that requires passive scanning.

It could be possible for the scan results to include two entries for a
peer, one from the Listen state and the second one from the GO role. The
latter could be based on a Beason frame. If that happens and the entry
from GO is processed last, the P2P peer config_methods value could
potentially get cleared since Beacon frames do not include this
information in either WPS or P2P element. Avoid this by allowing the
config_methods value for P2P peers to be updated only if the new value
is non-zero.

Since there could be multiple carrier records, it is cleaner to build
only the WPS carrier record instead of full NFC connection handover
request within wpa_supplicant.

The capability itself isn't really affected by an OBSS
scan, only the HT operation must then be restricted to
20 MHz. Change this, and therefore use the secondary
channel configuration to determine the setting of the
OP_MODE_20MHZ_HT_STA_ASSOCED flag.
This shouldn't really change anything functionally,
it just makes the code a little less confusing and
is also needed to implement more dynamic bandwidth
changes if ever desired.

Commit 1a9f6509b3 added support for
fragmenting the P2P IE in Probe Response frames from a GO. However, it
did not take into account the possibility of Wi-Fi Display IE being
included in the same buffer and caused a regression for the cases where
Wi-Fi Display is enabled. Fix this by building the possibly fragmented
P2P IE first and then concatenating the separate IEs together.

When AP mode operation reject the client, nl80211 layer advertises the
connect failed event with the reason for failures (for example, max
client reached, etc.) using NL80211_CMD_CONN_FAILED.
This patch adds some debug messages whenever such an event is received
from the nl80211 layer and also the same event is posted to the upper

If an implicit TDLS set up request is obtained on an existing link or an
to be established link, the previous link was not removed. This commit
disables the existing link on a new set up request. Also,
wpa_tdls_reneg() function was invoking wpa_tdls_start() on an already
existing peer for the case of internal setup, which is incorrect. Thus
the invocation of wpa_tdls_start() is removed in wpa_tdls_reneg() and
also this function is renamed to wps_tdls_remove() as it does not
renegotiation rather shall remove the link (if any) for the case of
external setup.

Peer entries were getting added on every discover request from the peer,
thus resulting in multiple entries with the same MAC address. Ensures

GAS server used the same public_action_cb mechanism as P2P to process
Action frames. This ended up overriding P2P processing of Action frames
while running an AP/GO interface with a build that enables Interworking
(e.g., for Hotspot 2.0) and a driver that uses hostapd for AP mode
SME/MLME. Fix this by adding a separate callback registration for the
GAS server. This should really be cleaned up by supporting arbitrary
number of callback handlers, but for now, this addresses the regression
with a minimal change.

When scan failed, the wpa_driver_nl80211_scan method tried
to recursively call itself, but it passed in the wrong argument
for the void*, and so then it crashed accessing bad memory.
With this fix, hostapd still will not retry the scan later, but
at least it will exit cleanly and won't polute the file system
with core files.

Each GO Negotiation Request is (re)tried with an unique dialog token and
a GO Negotiation Response / Confirmation from the peer with a mismatched
dialog token is ignored which could result in a failure in this group
formation attempt. Thus, the P2P device would continue retrying the GO
Negotiation Request frames till the GO Negotiation Response frame with a
matching dialog token is received. To avoid the failures due to the
dialog token mismatch in retry cases if the peer is too slow to reply
within the timeout, the same dialog token value is used for every retry
in the same group formation handshake.
It should be noted that this can result in different contents of the GO
Negotiation Request frame being sent with the same dialog token value
since the tie breaker bit in GO Intent is still toggled for each
attempt. The specification is not very clear on what would be the
correct behavior here. Tie breaker bit is not updated on
"retransmissions", but that is more likely referring to the layer 2
retransmission and not the retry at higher layer using a new MMPDU.
