Some time ago it was found some drivers are setting their hw/ucode RX
filters restrictively enough to prevent broadcast DPP Action frames from
being received at upper layers in the stack.
A set of patches was introduced to the kernel and
ath9k driver as well as wpa_supplicant, e.g.,
a39e9af90 ("nl80211: DPP listen mode callback")
4d2ec436e ("DPP: Add driver operation for enabling/disabling listen mode")
However, the hostapd code itself was not calling the new multicast
registration. As such the AP side of things wasn't working as expected
in some scenarios. I've found this while trying to get ath9k working as
an AP Responder/Configurator.
The problem wasn't seen on, e.g., mac80211 hwsim driver.
Extend the wpa_supplicant mechanism to work with hostapd as well.

hostapd (and wpa_supplicant in AP mode) was internally updating the STA
flags on disconnection cases to remove authorization and association.
However, some cases did not result in immediate update of the driver STA
entry. Update all such cases to send out the update to the driver as
well to reduce risk of race conditions where new frames might be
accepted for TX or RX after the port authorization or association has
been lost and configured keys are removed.

PASN authentication can be performed while a station interface is
connected to an AP. To allow sending PASN frames while connected, extend
the send_mlme() driver callback to also allow a wait option. Update the
relevant drivers and wpa_supplicant accordingly.
hostapd calls for send_mlme() are left unchanged, since the wait option
is not required there.

Add the new set_key() parameter "key_flag" to provide more specific
description of what type of a key is being configured. This is needed to
be able to add support for "Extended Key ID for Individually Addressed
Frames" from IEEE Std 802.11-2016. In addition, this may be used to
replace the set_tx boolean eventually once all the driver wrappers have
moved to using the new key_flag.
The following flag are defined:
KEY_FLAG_MODIFY
Set when an already installed key must be updated.
So far the only use-case is changing RX/TX status of installed
keys. Must not be set when deleting a key.
KEY_FLAG_DEFAULT
Set when the key is also a default key. Must not be set when
deleting a key. (This is the replacement for set_tx.)
KEY_FLAG_RX
The key is valid for RX. Must not be set when deleting a key.
KEY_FLAG_TX
The key is valid for TX. Must not be set when deleting a key.
KEY_FLAG_GROUP
The key is a broadcast or group key.
KEY_FLAG_PAIRWISE
The key is a pairwise key.
KEY_FLAG_PMK
The key is a Pairwise Master Key (PMK).
Predefined and needed flag combinations so far are:
KEY_FLAG_GROUP_RX_TX
WEP key not used as default key (yet).
KEY_FLAG_GROUP_RX_TX_DEFAULT
Default WEP or WPA-NONE key.
KEY_FLAG_GROUP_RX
GTK key valid for RX only.
KEY_FLAG_GROUP_TX_DEFAULT
GTK key valid for TX only, immediately taking over TX.
KEY_FLAG_PAIRWISE_RX_TX
Pairwise key immediately becoming the active pairwise key.
KEY_FLAG_PAIRWISE_RX
Pairwise key not yet valid for TX. (Only usable with Extended Key ID
support.)
KEY_FLAG_PAIRWISE_RX_TX_MODIFY
Enable TX for a pairwise key installed with KEY_FLAG_PAIRWISE_RX.
KEY_FLAG_RX_TX
Not a valid standalone key type and can only used in combination
with other flags to mark a key for RX/TX.
This commit is not changing any functionality. It just adds the new
key_flag to all hostapd/wpa_supplicant set_key() functions without using
it, yet.

The HE capabilities are no longer per PHY but per iftype on this
specific PHY. It is therefore no longer enough to just parse the AP
capabilities.
The he_capabilities are now duplicated to store all information for
IEEE80211_MODE_* which hostap cares about. The nl80211 driver fills in
this information when the iftype supports HE. The rest of the code still
only uses the IEEE80211_HE_AP portion but can be extended later to also
use other HE capabilities.

This implements the required functionality in hostapd to facilitate OWE
connection with the AP SME-in-driver cases. Stations can either send DH
IE or PMKID (in RSNE) (or both) in Association Request frame during the
OWE handshake. The drivers that use this offload mechanism do not
interpret this information and instead, pass the same to hostapd for
further processing. hostapd will either validate the PMKID obtained from
the STA or generate DH IE and further indicate the same to the driver.
The driver further sends this information in the Association Response
frame.

for cases where the driver supports DFS channels, but for some reason a

Previously, the chanlist parameter could have been used for this, but

IEEE Std 802.11-2012, 10.19 (Public Action frame addressing) specifies
that the wildcard BSSID value is used in Public Action frames that are
transmitted to a STA that is not a member of the same BSS. hostapd used
to use the actual BSSID value for all such frames regardless of whether
the destination STA is a member of the BSS.
Fix this by using the wildcard BSSID in cases the destination STA is not
a member of the BSS. Leave group addressed case as-is (i.e., the actual
BSSID), since both values are accepted. No such frames are currently
used, though.
This version is still using the AP BSSID value in the Address 3 field
for GAS response frames when replying to a GAS request with AP BSSID
instead of Wildcard BSSID. This is left as a workaround to avoid
interoperability issues with deployed STA implementations that are still
using the non-compliant address and that might be unable to process the
standard compliant case.

When an AP interface it created, it is also setup and subscribes
for management frames etc. However, when the interface is added by
wpa_supplicant, setting up for AP operations is redundant because
it will be done by wpa_supplicant on wpa_drv_init() when setting
the interface mode to AP.
In addition, it may cause wpa_supplicant to fail initializing the
interface as it will try to subscribe for management frames on this
interface but the interface is already registered.
Change this, so when adding an AP interface, make setting up the AP
optional, and use it only when the interface is added by hostapd but not
when it is added by wpa_supplicant.
