Try to fetch the list of supported AKM suite selectors from the driver
through the vendor interface
QCA_NL80211_VENDOR_SUBCMD_GET_SUPPORTED_AKMS. If that command is
available and succeeds, use the returned list to populate the
wpa_driver_capa key_mgmt information instead of assuming all
cfg80211-based drivers support all AKMs. If the driver does not support
this command, the previous behavior is maintained.

This new QCA vendor command is used to query the supported AKM suite
selectors from the driver. There has been no such capability indication
from the driver and thus the current user space has to assume the driver
to support all the AKMs. This may be the case with some drivers (e.g.,
mac80211-based ones) but there are cfg80211-based drivers that implement
SME and have constraints on which AKMs can be supported (e.g., such
drivers may need an update to support SAE AKM using
NL80211_CMD_EXTERNAL_AUTH). Allow such drivers to specify the exact set
of supported AKMs so that user space tools can determine what network
profile options should be allowed to be configured. This command returns
the list of supported AKM suite selectors in the attribute
NL80211_ATTR_AKM_SUITES.

When using LibreSSL instead of OpenSSL, linkage of hostapd executable
fails with the following error when using some LibreSSL versions
../src/crypto/tls_openssl.o: In function `tls_verify_cb':
tls_openssl.c:(.text+0x1273): undefined reference to `ASN1_STRING_get0_data'
../src/crypto/tls_openssl.o: In function `tls_connection_peer_serial_num':
tls_openssl.c:(.text+0x3023): undefined reference to `ASN1_STRING_get0_data'
collect2: error: ld returned 1 exit status
make: *** [Makefile:1278: hostapd] Error 1
ASN1_STRING_get0_data is present in recent OpenSSL, but absent in some
versions of LibreSSL (confirmed for version 2.6.5), so fallback needs to
be defined in this case, just like for old OpenSSL.
This patch was inspired by similar patches to other projects, such as
spice-gtk, pjsip.

Advertise vendor specific Multi-AP IE in (Re)Association Request frames
and process Multi-AP IE from (Re)Association Response frames if the user
enables Multi-AP fuctionality. If the (Re)Association Response frame
does not contain the Multi-AP IE, disassociate.
This adds a new configuration parameter 'multi_ap_backhaul_sta' to
enable/disable Multi-AP functionality.
Enable 4-address mode after association (if the Association Response
frame contains the Multi-AP IE). Also enable the bridge in that case.
This is necessary because wpa_supplicant only enables the bridge in
wpa_drv_if_add(), which only gets called when an interface is added
through the control interface, not when it is configured from the
command line.

The purpose of Multi-AP specification is to enable inter-operability
across Wi-Fi access points (APs) from different vendors.
This patch introduces one new configuration parameter 'multi_ap' to
enable Multi-AP functionality and to configure the BSS as a backhaul
and/or fronthaul BSS.
Advertise vendor specific Multi-AP capabilities in (Re)Association
Response frame, if Multi-AP functionality is enabled through the
configuration parameter.
A backhaul AP must support receiving both 3addr and 4addr frames from a
backhaul STA, so create a VLAN for it just like is done for WDS, i.e.,
by calling hostapd_set_wds_sta(). Since Multi-AP requires WPA2 (never
WEP), we can safely call hostapd_set_wds_encryption() as well and we can
reuse the entire WDS condition.
To parse the Multi-AP Extension subelement, we use get_ie(): even though
that function is meant for parsing IEs, it works for subelements.

After the network changed to a new channel, perform an SA Query with the
AP after a random delay if OCV was negotiated for the association. This
is used to confirm that we are still operating on the real operating
channel of the network. This commit is adding only the station side
functionality for this, i.e., the AP behavior is not changed to
disconnect stations with OCV that do not go through SA Query.

Include an OCI element in SA Query Request and Response frames if OCV
has been negotiated.
On Linux, a kernel patch is needed to let clients correctly handle SA
Query Requests that contain an OCI element. Without this patch, the
kernel will reply to the SA Query Request itself, without verifying the
included OCI. Additionally, the SA Query Response sent by the kernel
will not include an OCI element. The correct operation of the AP does
not require a kernel patch.
Without the corresponding kernel patch, SA Query Requests sent by the
client are still valid, meaning they do include an OCI element.
Note that an AP does not require any kernel patches. In other words, SA
Query frames sent and received by the AP are properly handled, even
without a kernel patch.
As a result, the kernel patch is only required to make the client properly
process and respond to a SA Query Request from the AP. Without this
patch, the client will send a SA Query Response without an OCI element,
causing the AP to silently ignore the response and eventually disconnect
the client from the network if OCV has been negotiated to be used.

It is better not to process a new (most likely repeated) FILS HLP
request if a station retransmits (Re)Association Request frame before
the previous HLP response has either been received or timed out. The
previous implementation ended up doing this and also ended up
rescheduling the fils_hlp_timeout timer in a manner that prevented the
initial timeout from being reached if the STA continued retransmitting
the frame. This could result in failed association due to a timeout on
the station side.
Make this more robust by processing (and relaying to the server) the HLP
request once and then ignoring any new HLP request while the response
for the relayed request is still pending. The new (Re)Association
Request frames are otherwise processed, but they do not result in actual
state change on the AP side before the HLP process from the first
pending request is completed.
This fixes hwsim test case fils_sk_hlp_oom failures with unmodified
mac80211 implementation (i.e., with a relatively short retransmission
timeout for (Re)Association Request frame).
