Change the nl80211 driver in wpa_supplicant to correctly handle
connecting to a new AP through cfg80211 without SME capability. As
before, the driver will disconnect from the previously associated AP,
but now we attempt to immediately connect to our intended AP. This
prevents us from blacklisting the AP we were trying to connect to
because of a semantic mismatch between cfg80211 and wpa_supplicant. The
disconnect/connect patch generates a local disconnect nl80211 event
which we discard because we're already correctly tracking the pending
association request.
In detail:
cfg80211 does not support connecting to a new BSS while already
connected to another BSS, if the underlying driver doesn't support
separate authenticate and associate commands. wpa_supplicant is written
to expect that this is a supported operation, except for a little error
handling that disconnects from the current BSS when roaming fails and
relies on autoconnect logic to reconnect later. However, this failure to
connect is incorrectly attributed to the new AP we attempted to
associate with, rather than a local condition in cfg80211.
The combined effect of these two conditions is that full-mac drivers
accessible through cfg80211 but without SME capability take a long time
to roam across BSS's because wpa_supplicant will:
1) Fail to associate for local reasons
2) Disconnect and return that the association request failed
3) Blacklist the association target (incorrectly)
4) Do a scan
5) Pick a less desirable AP to associate with

This uses the recent cfg80211 changes to allow SAE authentication to be
implemented with the nl80211 driver interface.

These values are used with WAPI and CCX and reserving the definitions
here reduces the number of merge conflicts with repositories that
include these functions.

This avoids extra latency caused by establishing an aggregation session
and makes the initial connection attempt more reliable

This patch fixes an issue where removing a WDS VLAN interface also
removed the main AP interface from the same bridge.

This driver_op can now be used in station mode, too, to fetch
information about the connection with the AP, so allow this to be used
even if wpa_supplicant is built without AP mode support.

This allows both hostapd and wpa_supplicant to be used to derive and
configure keys for GCMP. This is quite similar to CCMP key
configuration, but a different cipher suite and somewhat different rules
are used in cipher selection. It should be noted that GCMP is not
included in default parameters at least for now, so explicit
pairwise/group configuration is needed to enable it. This may change in
the future to allow GCMP to be selected automatically in cases where
CCMP could have been used.
This commit does not included changes to WPS or P2P to allow GCMP to be
used.

Use the NL80211_IFACE_COMB_NUM_CHANNELS value > 1 as a trigger for
enabling support for P2P multichannel channel concurrency. This does not
handle all possible details of enforcing driver capabilities, but it is
a good first step for allowing nl80211 drivers to enable multichannel
concurrency.

Commit a11241fa11 removed the 802.11b rate
enabling/disabling code from wpa_driver_nl80211_set_mode() and while
doing that, removed the only place where drv->disabled_11b_rates was
set. Fix this by updating the flag in nl80211_disable_11b_rates(). In
addition, re-enable the 802.11b rates when changing to non-P2P mode.
Signed-hostap: Jouni Malinen <j@w1.fi>
Right now 11b rates are masked out while creating a P2P interface,
but this is always failing as the interface is down. Most drivers
allow to configure rates only when the interface is UP and running.
So let us disable 11b rates when interface type is changed into a
P2P type and it is UP and running.

Couple of functions did not verify that nla_put_nested() succeeded. Fix
these by checking the return value and handling error cases cleanly.

Allow the user to configure an RSSI threshold in dBm below which the

Some drivers may independently decide to switch channels. Handle this by
updating the hostapd and wpa_supplicant AP and GO configuration.

The control message received from the kernel needs some space, but
there's no need for the strange typing that breaks clang compilation.
