This uses the new nl80211 attributes to allow the connect command to
provide bssid and freq hints to the driver without limiting roaming to
the specific BSS/frequency. This can be used by drivers that perform
internal BSS selection (WPA_DRIVER_FLAGS_BSS_SELECTION) as a candidate
for initial association.

Commit 795baf773f ('hostapd: Filter
channel list updated events after country code change') uses the
EVENT_CHANNEL_LIST_CHANGED data pointer, but it updated only one of the
callers to provide that data. NL80211_CMD_REG_BEACON_HINT event was
still sending the event without the initiator data and resulted in NULL
pointer dereference, e.g., if a scan was run while hostapd was running
and the driver was in world roaming state and enabled a channel for
active scans.

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.

Replace channel_switch_supported flag of the

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.

WPA_CIPHER_* and CIPHER_* are used for the exact same set of cipher
suites with the main difference being that the WPA_CIPHER_* version is
suitable to be used as a bitfield. Similarly, WPA_KEY_MGMT_* and
KEY_MGMT_* have similar design for AKMs. There is no need to maintain
two separate copies of the definitions since the bitfield compatible
version can be used for both needs. Get rid of the CIPHER_* and
KEY_MGMT_* versions to clean up the implementation by getting rid of
unnecessary mapping functions.

The option of handling upper layer P2P management operations within the
driver/firmware was originally planned to be used with wpa_supplicant,
but this has not really happened and there is no clear sign of this
being needed in the near term either. This functionality has not been
completed and it is certainly not being kept up-to-date or tested. As
such, it is best to remove it for now and if this or something similar
is needed in the future, it can be brought back once a clear need for it
has been demonstrated first.

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.
Signed-hostap: Jouni Malinen <j@w1.fi>
Action frame RX report through EVENT_RX_ACTION did not indicate whether
the frame was protected or not even though that information is available
in mlme_event_mgmt(). hostapd_rx_action() has a workaround for setting
the protected flag for SA Query frames, but that did not apply for other
frames, like FT Action. This broke FT-over-DS when PMF is enabled with
newer kernel versions (i.e., the ones that do not use monitor interface
for receiving management frames).

The BSS table, scan timeout, and related functionality should use

Unfortunately, these are all connected, so the patch can't be split

Add csa_settings struct which holds parameters for CSA. Change driver

We were not filtering the EVENT_CHANNEL_LIST_CHANGED events based on the
regulatory hint initiator. So wait for EVENT_CHANNEL_LIST_CHANGED event
after our own change was triggered even when regulatory hint initiator
was the driver. This could result in the wait for the channel list to be
updated to be terminated before the real change has occurred and as
such, old channel list remaining in use when configuring
hostapd/wpa_supplicant country parameter. Fix this by filtering the
hints according to the initiator and only regulatory hints initiated by
user will be used to stop the wait.

If hostapd is requested to set the country code and the previous country
code differs from the new one, the channel list information from the
driver may change. This change may not be instant, so wait for an
EVENT_CHANNEL_LIST_CHANGED event before continuing interface setup with
fetching of the channel list information. This fixes issues where the
selected channel is not available based on the previous regulatory data
and update through CRDA takes some time.

It is possible that when trying to remove a dynamically added interface,
changing its type to station mode is not possible (since the kernel does
not support so in its interface combinations).
Since P2P interfaces are always dynamically added, avoid changing their

callbacks, assuming that the interface is about to be removed.
