253f2e3795 P2P: Apply unsafe frequency rules to available channels
This adds a QCA vendor specific nl80211 event to allow the driver to
indicate a list of frequency ranges that should be avoided due to
interference or possible known co-existance constraints. Such
frequencies are marked as not allowed for P2P use to force groups to be
formed on different channels.

If a P2P GO is operating on a channel that the driver recommended not to
use, a notification about this is sent on the control interface and
upper layer code may decide to tear down the group and optionally
restart it on another channel. As a TODO item, this could also be changed
to use CSA to avoid removing the group.

949938aadf Ask driver to report only new scan results if requested
If the BSS table within wpa_supplicant is flushed, request the driver to
flush its own scan result table during the next scan. This can avoid
unexpected old BSS entries showing up after BSS_FLUSH or FLUSH command
in cases where the driver may maintain its internal cache of scan
results (e.g., cfg80211 BSS table persists at least for 15 seconds).

In addition to doing this automatically on BSS_FLUSH/FLUSH, a new SCAN
command argument, only_new=1, can be used to request a manual scan
request to do same. Though, it should be noted that this maintains the
BSS table within wpa_supplicant. BSS_FLUSH followed by SCAN command can
be used to clear all BSS entries from both the driver and
wpa_supplicant.

6f06766e71 nl80211: Fix nl_mgmt handling in partial error case
If Action frame registration in nl80211_mgmt_subscribe_non_ap() failed
for any frame type, the previous implementation skipped
nl80211_mgmt_handle_register_eloop() call. This is not desirable since
none of the Action frame types could be received and even worse, the
following nl80211_destroy_eloop_handle() call for nl_mgmt would likely
result in crashing the process due to the ELOOP_SOCKET_INVALID XOR
operation. This could be triggered at least in a P2P group interface
startup failure case.

4ea6a47133 nl80211: Prefer newer scan result over older during duplicate removal
Previously, it was possible for bss_info_handler() to end up dropping a
newer scan result entry if there were two entries with the same BSSID
and SSID (i.e., only frequency was different) and we were not associated
with either. This could happen, e.g., in some P2P use cases where device
discovery may happen on different channels. Fix this by checking the age
of the scan entries as well to prefer the most recent response.

dbfb8e82ff Remove unnecessary EVENT_RX_ACTION
This driver event was used separately for some Action frames, but all
the driver wrappers converted to this from information that would have
been enough to indicate an EVENT_RX_MGMT event. In addition, the
received event was then converted back to a full IEEE 802.11 management
frame for processing in most cases. This is unnecessary complexity, so
get rid of the extra path and use EVENT_RX_MGMT for Action frames as
well as other management frame subtypes.

795baf773f hostapd: Filter channel list updated events after country code change

such, old channel list remaining in use when configuring

hints according to the initiator and only regulatory hints initiated by

Previously, there could be two disconnection events in core
wpa_supplicant when going through a case of wpa_supplicant-requested
disconnection with a driver that implements SME internally. This could
result in undesired behavior when a disconnection is followed by a new
connection attempt before the extra event has been received (e.g.,
during fast reassoc or WPS provisioning). Avoid such issues by ignoring
locally generated disconnect events after requesting cfg80211 to
disconnect.

This makes the previously used ignore_next_local_disconnect more
consistent by setting the variable within
wpa_driver_nl80211_disconnect() so that both callers get the same
behavior.

a8c5b43ad3 nl80211: Roam correctly through cfg80211 without SME
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

edb9bfba89 nl80211: Disable 11b rates on configuring P2P interface
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.

536fd62dba nl80211: Recover from auth req ENOENT with a scan
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.

Set the NL80211_ATTR_CONTROL_PORT_NO_ENCRYPT flag for nl80211 to tell
drivers (mac80211) to not encrypt the EAPOL frames for WEP IEEE 802.1X.

a4ae123c3f nl80211: Pass cb to eloop function
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.

e4fb216769 nl80211: Store frequency in bss struct
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.
