8cd6b7bce8 hostapd/wpa_s: Use driver's extended capabilities
Some extended capabilities (I'm currently interested in "Operating Mode
Notification" for VHT) are implemented by the kernel driver and exported
in nl80211. Use these in hostapd/wpa_supplicant.

65a32cdbcb AP: Fix infinite loop in WPA state machine when out of random bytes
When the OS is out of random bytes in SM_STATE(WPA_PTK, AUTHENTICATION2)
in ap/wpa_auth.c, hostapd sends the sm to state DISCONNECT without
clearing ReAuthenticationRequest, resulting in an infinite loop.
Clearing sm->ReAuthenticationRequest using gdb fixes the running hostapd
instance for me. Also sm->Disconnect = TRUE should be used instead of
wpa_sta_disconnect() to make sure that the incomplete ANonce does not
get used.

Fix this issue by resetting sm->ReAuthenticationRequest even if the STA
gets disconnected and use sm->Disconnect instead of
wpa_sta_disconnect().

a5f61b2b87 Fix OLBC non-HT AP detection to check channel
A non-HT capable AP on any channel could have triggered us to enable
protection regardless of own operating channel if the driver delivered
Beacon frames from other channels. The channel detection in ap_list is
not exactly ideal, but most cases can be handled by checking ap->channel
against the currently configured channel (or secondary channel in case
of HT40).

Commit 6b56cc2d97 added a possible call to
p2p_reset_pending_pd() prior to checking config_methods match between
our request and peer response. That reset call could clear

864fe3a47c TDLS: Fix TDLS Setup Request processing in existing-peer cases
wpa_tdls_peer_free() ended up getting called after some of the
parameters from the TDLS Setup Request frame were copied into the struct
wpa_tdls_peer information. This could result in continuing with cleared

capabilities correctly in such case.

Commit 50285f5ca8 changed number of rules

the currently used operating channel on a virtual interface that is
shared by the same radio is preferred to avoid costs related to
multi-channel concurrency. Fix this regression by making the P2P module

priority when re-selecting the channel during negotiation.

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.
