In multiple BSSes scenario for the drivers that do not use
monitor interface and do not implement AP SME, RX MGMT
frame subscription happens only for the default bss (first_bss).
Subscribe for RX MGMT frames for such BSSes.

Commit e4fb216769 moved frequency
storage from driver struct to bss struct and is assigned in
wpa_driver_nl80211_set_freq. As this wpa_driver_nl80211_set_freq is
triggered only on the first_bss, bss->freq for other BSSes is never
being set to the correct value. This sends MLME frames on frequency zero
(initialized value of freq) for BSSes other than the first.
To fix this derive frequency value from first_bss.

A P2P Action frame may need to be sent on another channel than the GO's
operating channel. This information was lost in
wpa_driver_nl80211_send_action() in the case the interface was in AP
mode. Pass the frequence and related parameters to send_mlme mechanism
to allow the correct frequence to be used with the send frame command in
AP (P2P GO) mode.

The cookie value needs to be fetched in GO mode, too, to be able to
indicate TX status callbacks with drivers that handle AP mode SME
functionality internally. This fixes issues with client discoverability
where TX status callback for GO Discoverability Request is needed to
trigger the GO to send Device Discoverability Response.
The deauthentication and disassociation events from nl80211 were being
processed identically regardless of whether the frame was generated by
the local STA or the AP. This resulted in fast reconnection mechanism
getting triggered even in the case where the disconnection was detected
locally (e.g., due to beacon loss) while this was supposed to happen
only in the case where the AP is sending an explicit Deauthentication
or Disassociation frame with a specific reason code.
Fix this by adding a new deauth/disassoc event variable to indicate
whether the event was generated locally.

The offchanok parameter is hardcoded to one in number of paths and that
added NL80211_ATTR_OFFCHANNEL_TX_OK attribute to NL80211_CMD_FRAME
unconditional. cfg80211 rejects this with EINVAL if the driver does not
indicate support for offchannel TX. Fix this by not requesting
offchannel TX depending on driver capabilities. Remain-on-channel
operation was used for those cases anyway, so the additional attribute
was not really needed for these in the first place.

When nl80211_setup_ap() has enabled Probe Request reporting, this must
not be disabled when P2P Listen state is stopped to avoid breaking AP
mode operations. This could happen, e.g., if a Probe Request frame was
received from a P2P device that the we are trying to invite to our group
(i.e., when operating in GO role). p2p_probe_req_rx() calls
p2p_invite_start() in this case and that ends up calling
p2p->cfg->stop_listen() which calls probe_req_report() driver op.

Poll command may be enough for mac80211 to figure out whether monitor

For example, ath6kl needs to get use_monitor disabled.

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.

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.
