For various P2P use cases, it is useful to have more accurate timestamp

cfg80211 caches the scan results according the channel number. Due to

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

Storing the address in the BSS instead of the DRV struct makes it usable
for hostapd and thus gets rid of the linux_get_ifhwaddr() call when
receiving a spurious frame.

If Provision Discovery Request is sent for GO role (i.e., P2P Group ID
attribute is included), add the group interface name to the control
interface event on the GO. This makes it easier to figure out which
ctrl_iface needs to be used for wps_pbc/wps_pin command to authorize
the joining P2P client.

This can be used to request Provision Discovery Request to be sent
for the purpose of joining a running group, e.g., to request the GO
to display a PIN that we can then use with p2p_connect join command.

Since the nl_cache is not used anymore, there is no need for maintaining
the struct nl80211_handles wrapper for struct nl_handle. Clean this up
by using nl_handle directly.

This is a rewrite of Ben Greear's patch, making the
nl80211 code use just a single multicast event socket.

When running AP mode, we need to receive beacons over overlapping BSSes
to handle protection. Use the new nl80211 command for this. As the
command works per wiphy (and we don't want to receive the Beacon frames
multiple times) add an abstraction that keeps track of per-wiphy data.

These events are necessary to send deauth frames to
stations sending spurious data frames. Subscribe to
them on the per-BSS event socket.
Signed-hostap: Johannes Berg <johannes.berg@intel.com>
To achieve this, multiple things are needed:
1) since hostapd needs to handle *all* action frames,
make the normal registration only when in a non-AP
mode, to be able to do this use the new socket
2) store the frequency in each BSS to be able to give
the right frequency to nl80211's mgmt-tx operation
3) make TX status processing reject non-matched cookie
only in non-AP mode
The whole thing depends on having station-poll support
in the kernel. That's currently a good indicator since
the kernel patches are added together.

When using authentication retry within driver_nl80211.c, a failure on the
second attempt has to be indicated with a driver event since the return
code from wpa_driver_nl80211_authenticate() is not actually delivered to
the core code in that case.
Signed-hostap: Jouni Malinen <j@w1.fi>
cfg80211 rejects NL80211_CMD_AUTHENTICATE with ENOENT if the BSS entry
for the target BSS is not available. This can happen if the cfg80211
entry has expired before wpa_supplicant entry (e.g., during a suspend).
To recover from this quickly, run a single channel scan to get the
cfg80211 entry back and then retry authentication command again. This
is handled within driver_nl80211.c to keep the core wpa_supplicant
implementation cleaner.

By passing the nl_cb as the context to the eloop function we can
(in the next patch) use the same eloop function for BSS events.

Storing the frequency in the bss struct allows using it for frame
commands in AP mode and not relying on the driver struct as much, which
is good for hostapd mode.

This is based on the Android driver_cmd changes that are converted to
use the sched_scan/stop_sched_scan driver_ops for the case where the

(jm: This is based on the Android change that used driver_cmd. The same
implementation is used for the actual driver interface, but the commands
are now accessed through sched_scan/stop_sched_scan driver_ops instead
of driver_cmd)
IW_ENCODE_ALG_PMK and IW_ENC_CAPA_4WAY_HANDSHAKE are not defined in the
Android tree, so add compatibility defines for these.

cfg80211 will reject the NL80211_CMD_START_SCHED_SCAN if too many
match sets are requested. To avoid being completely unable to start
any scheduled scans, skip setting these filters if the driver did
not advertise support for large enough number of match sets.

It's not really valid to send off-channel in all cases,
so pass whether it should be allowed or not and don't
set it in the AP case.
Also, to get the right ifindex for hostapd, pass a bss
pointer instead of the drv pointer.

In some situations it might be benefical to send a unicast frame without
the need for getting it ACKed (probe responses for example). In order to
achieve this add a new noack parameter to the drivers send_mlme callback
that can be used to advise the driver to not wait for an ACK for this
frame.

If the kernel supports this, don't use manual null
data frame transmissions. This is one thing to get
rid of cooked monitor interfaces.
Signed-hostap: Johannes Berg <johannes.berg@intel.com>
The non-monitor TX currently uses a normal L2 abstraction
socket, but that will also receive frames we don't want,
so use a plain socket that isn't bound for RX. This might
be possible using the L2 abstraction, but we need a plain
socket later for getting TX status events here.

This changes the auto-detection of whether or not the device contains
the AP SME away from monitor interface addition failing to the explicit
attribute in nl80211. Keep the old auto-detection for a little while so
that ath6kl isn't broken right away.

This patch implements shared_freq handler for driver_nl80211.c. If a
"p2p_group_add" happens after legacy STA association, then this patch
will help to start the GO on the same frequency. This is useful when
supplicant is started on multiple interface running over a singly "PHY"
and the station interface is not used for the P2P device operations.
For example, wpa_supplicant -iwlan0 .. -N -iwlan1 ... and wlan0 is used
for station connection and wlan1 as the P2P device interface.

WEXT is not really changing anymore and more or less all Linux

Use a driver_ndis.c specific initialization function to fill in the
wpa_driver_ops information to make it easier to modify struct
wpa_driver_ops in the future. Being able to build driver_ndis.c
with MSVC was the only reason for having to maintain the same order
of function pointers in struct wpa_driver_ops and for having to
update driver_ndis.c for all changes in that structure.

In scan.c, merge a channel's noise value into the scan results. When
comparing scan results, compute the signal-to-noise ratio and use it
when available. Prefer a 5 GHz network if its SNR is really big (> 30)
or if its SNR is relatively close to the other network's.
Instead of hardcoding IEEE 802.11b rates to be disabled whenever
P2P support is built in and supported by the driver, do this only
when an interface is set to P2P mode (both when adding a new
interface and when changing the interface mode). This re-enables
use of IEEE 802.11b APs with CONFIG_P2P=y builds.
