The QCA_NL80211_VENDOR_SUBCMD_GET_HE_CAPABILITIES attributes are not
up-to-date with the latest P802.11ax/D4.0 capabilities and would need to
be updated or replaced. Since the variables from this functionality were
not used for anything in practice, it is easier to simply remove this
functionality completely to avoid issues with upcoming updates to use
upstream nl80211 information to determine HE capabilities.
This is practically reverting the commit ca1ab9db2a ("hostapd: Get

When processing the NL80211_CMD_PROBE_CLIENT command response, the
nl80211 layer in the kernel sends a response containing the cookie
associated with the client probe request. This response was not handled
by driver_nl80211.c when sending the command, and it was mistakenly
handled as an asynchronous event. This incorrect event did not include
the MAC/ACK attributes, so it was ignored in practice, but nevertheless,
the command response should not be processed as an event.
Fix this by reading the response as part of the sending the command
flow.

Move event.assoc_info.freq selection to be after the

happened between the association request and completion of association.
Furthermore, update bss->freq based on assoc_freq to make that
information a bit more useful for station mode. It was already updated
after channel switches during association, but not at the beginning of
association.

This fixes some issues where bss->freq could have been used to replace
the current operating channel when sending out a management frame.
bss->freq has not been consistently used to track the current operating
channel in station mode, so it should not be trusted for this type of
uses. Clearing it makes this a bit more robust by at least avoiding the
cases of information from past association being used.

hostapd configuration parameters fragm_threshold and rts_threshold were
documented to disable the threshold with value -1 and not change driver
configuration if the parameter is not included. However, -1 was mapped
into not changing the driver value, so the explicit disabling part did
not work.
Replace the default values for these to be -2 so that explicitly set
configuration value -1 can be distinguished from the case of not
including the parameter. Map the -1 value to a driver request to disable
the threshold. Ignore any error from this operation just in case to
avoid breaking functionality should some drivers not accept the (u32) -1

We do not need such payload in the acknowledgment, so adding it uses

this received message buffer and it would be inconvenient for
wpa_supplicant/hostapd to try to clear it with the current libnl design

that keys might be left unnecessarily in heap memory. Avoid this by

The purpose of the Lowest Acceptable PN (lpn) parameters in the MACsec
SAK Use parameter set is to enforce delay protection. Per IEEE Std
802.1X-2010, Clause 9, "Each SecY uses MKA to communicate the lowest PN
used for transmission with the SAK within the last two seconds, allowing
receivers to bound transmission delays."
When encoding the SAK Use parameter set the KaY should set llpn and olpn
to the lowest PN transmitted by the latest SAK and oldest SAK (if
active) within the last two seconds. Because MKPDUs are transmitted
every 2 seconds (MKA_HELLO_TIME), the solution implemented here
calculates lpn based on the txsc->next_pn read during the previous MKPDU
transmit.
Upon receiving and decoding a SAK Use parameter set with delay
protection enabled, the KaY will update the SecY's lpn if the delay
protect lpn is greater than the SecY's current lpn (which is a product
of last PN received and replay protection and window size).

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.

Add support for negotiating WNM Collocated Interference Reporting. This
allows hostapd to request associated STAs to report their collocated
interference information and wpa_supplicant to process such request and
reporting. The actual values (Collocated Interference Report Elements)
are out of scope of hostapd and wpa_supplicant, i.e., external
components are expected to generated and process these.
For hostapd/AP, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration. STAs are requested to perform
reporting with "COLOC_INTF_REQ <addr> <Automatic Report Enabled> <Report
Timeout>" control interface command. The received reports are indicated
as control interface events "COLOC-INTF-REPORT <addr> <dialog token>
<hexdump of report elements>".
For wpa_supplicant/STA, this mechanism is enabled by setting
coloc_intf_reporting=1 in configuration and setting Collocated
Interference Report Elements as a hexdump with "SET coloc_intf_elems
<hexdump>" control interface command. The hexdump can contain one or
more Collocated Interference Report Elements (each including the
information element header). For additional testing purposes, received
requests are reported with "COLOC-INTF-REQ <dialog token> <automatic
report enabled> <report timeout>" control interface events and
unsolicited reports can be sent with "COLOC_INTF_REPORT <hexdump>".
This commit adds support for reporting changes in the collocated
interference (Automatic Report Enabled == 1 and partial 3), but not for
periodic reports (2 and other part of 3).

That's because wpa_supplicant computed the PMKID using the wrong (old)
MAC address used during the scan. wpa_supplicant updates own_addr when
the interface goes up, as the MAC can only change while the interface
is down. However, drivers don't report all interface state changes:
for example the nl80211 driver may ignore a down-up cycle if the down
message is processed later, when the interface is already up. In such
cases, wpa_supplicant (and in particular, the EAP state machine) would
continue to use the old MAC.
Add a new driver event that notifies of MAC address changes while the
interface is active.

Add generic DFS offload support using the nl80211 feature that was
recently added to the mac80211-next tree. This uses the already
available DFS offload infrastructure that was previously used with
vendor specific definitions and just sets necessary flags (DFS_OFFLOAD
ext_feature) and forawrds CAC_STARTED event for processing.

The nl80211 driver can report STA_OPMODE notification event as soon as
it receives an HT/VHT Action frame about modification of station's SMPS
mode/bandwidth/RX NSS. Add support to parse such events.

This allows external application to get last ACK signal strength of the
last transmitted frame if the driver makes this information
(NL80211_STA_INFO_ACK_SIGNAL) available.

Now we can configure the network block so that it allows MFP setting for
the NL80211_CMD_CONNECT command. If the kernel finds an AP that requires
MFP, it'll be able to connect to it.
Note that since NL80211_MFP_OPTIONAL isn't supported for
NL80211_CMD_ASSOCIATE, we need to take the MFP configuration outside
nl80211_connect_common(). In addition, check that
NL80211_EXT_FEATURE_MFP_OPTIONAL is supported, to be backward compatible
with older kernels.

Add an event that indicates that the 4 way handshake was completed by
the driver.
This event is useful for networks that require 802.1X authentication.
The driver can use this event that a new connection is already
authorized (e.g. when the driver used PMKSA caching) and 802.1X
authentication is not required.

Add support for setting the PMK to the driver. This is used for
drivers that support 4-way handshake offload.

Set the WPA_DRIVER_FLAGS_4WAY_HANDSHAKE flag if the driver indicates
both 4-way handshake PSK and 802.1X support. Currently wpa_supplicant
doesn't distinguish between 4-way handshake for 802.1X and PSK, but
nl80211 API has different capabilities for each one.

The current cfg80211 limit for the maximum NL80211_ATTR_PMK length is
48, so anything larger than that will result in the operation completely
failing. Since the PMKSA entries can be used without the PMK for most
purposes (the main use case for PMK currently is offloaded FILS
authentication), try to go ahead by configuring only the PMKID for the
case where 64-octet PMK is needed (which is currently limited to only
DPP with NIST P-521 and brainpoolP512r1 curves). This can fix DPP
connections with drivers that expect to get the PMKID through this
interface while still leaving the actual 4-way handshake for user space.

This netlink socket handle owns the connect request and is further used
