When parsing a SAE Commit message, the temporary peer_rejected_groups
parameter was left to its old value in cases where the new SAE Commit
message did not include the Rejected Groups element. This could result
in unexpected behavior if a previously processed SAE Commit message
included a Rejected Groups element that claimed one of the enabled
groups to be rejected.
Explicitly clear the peer_rejected_groups value when parsing an SAE
Commit message without a Rejected Groups element to avoid rejecting the
new message based on some previously received incorrect information.
This avoids some potential denial-of-service issues during the lifetime
of the SAE temporary data.

Authentication rejection was found when doing fuzz testing even with a
valid SAE commit message when it was sent after a SAE commit message
that included an incorrect password identifier. The test steps for this
are as below:
1. Peer sends an abnormal commit message with incorrect password
identifier
2. APUT rejects as expected
3. Peer sends a valid commit message
4. APUT rejects again, which is not expected
In step 2, as the abnormal data fakes an empty password identifier
element, it passes sae_is_password_id_elem() checking. Memory is then
allocated for sae->tmp->pw_id. The authentication process then fails
due to no available password with this invalid password identifier.
In step 4, though the peer sends a valid commit message, APUT rejects
this SAE commit again due to no password identifier element (due to that
sae->tmp->pw_id being set), which is not expected.
Free the sae->tmp->pw_id field and set it to NULL when SAE commit
message processing fails due to an unknown password identifier so that
the bogus value is not used as a requirement for any consecutive SAE
commit from the same STA before the STA entry gets cleared.

Userspace tools can use QCA_WLAN_VENDOR_ATTR_CONFIG_IF_OFFLOAD_TYPE to
configure the different below acceleration features (hardware, software)
on a per interface basis.
0 - No acceleration Packets are processed through the Linux kernel
networking stack.
1 - Software based acceleration: Packets are processed through the
shortcut forwarding engine (SFE) to bypass the Linux networking stack
for improved throughput performance. This option is applicable for AP,
STA, and Mesh mode and available for all radio designs. From the
performance aspect, this option consumes more CPU compared to the other
two options. Linux traffic control can be further applied with this
option to have more control on the traffic flows.
2 - Hybrid acceleration (software and hardware acceleration combined):
Packets are processed through both hardware and software in this case.
Packet classification is done by the hardware and then the packets are
delivered to software along with classification results as meta data.
Software can choose to do more classification/QoS based on use cases.
This is applicable for AP, STA, and Mesh modes and is available for all
radio designs. From the performance aspect, this option consumes
relatively less CPU compared to the SFE option above. Linux traffic
control rules cannot be applied with this option.
3 - Hardware based acceleration : Packets are processed through special
hardware (Direct Switch) rings which can directly forward the packets
between ethernet hardware and Wi-Fi hardware with very less software
involvement. This is applicable only for AP and STA modes; not
applicable for Mesh mode. From the performance aspect, this option
consumes very much less CPU compared to the other options. Linux traffic
control rules cannot be applied when this option is used. This option is
applicable only for specific radio designs. When this option is not
available, the default option (SFE) would be configured.

If a non-PSC 6 GHz channel with bandwidth higher than 20 MHz is

The Primary Channel subfield is set to the channel number of the primary

Add a QCA vendor command for registering NL80211_CMD_GET_STATION
response as a unicast event when there is a NL80211_CMD_GET_STATION
request from any userspace module.
The driver will send the unicast events with the same netlink port ID
which is used by userspace application for sending the registration
command. If multiple registration commands are received with different
netlink port IDs, the driver will send unicast event with each netlink
port ID separately.
Userspace application can deregister the unicast events with disable
configuration. The registrations will be removed automatically by the
driver when the corresponding netlink socket is closed.
This will help avoid multiple NL80211_CMD_GET_STATION requests from
different userspace applications in short span. The userspace
application which registers for the unicast event can avoid sending
NL80211_CMD_GET_STATION request again if the response is available with
a recently received unicast event.

Add support for TWT responder for AP operating in HT and VHT modes by
introducing a new configuration parameter ht_vht_twt_responder. When
this is enabled, TWT responder mode support in HT and VHT modes is
enabled if the driver supports this and is disabled otherwise.

for_each_mld_link() macro used three nested for loops. Since now the
affliated links are linked together via a linked list, the logic can be
improved by using dl_list_for_each() macro instead which uses one for
loop.
Modify for_each_mld_link() macro to use dl_list_for_each() instead.

If the build path is long, the contents of the _DIRS variable can be
very long, since it repeats the same directories very often. In some
cases, this has triggered an "Argument list too long" build error.

If authentication fails repeatedly, e.g., because of a weak signal, the
link can end up in blocked state. If one of the nodes tries to establish
a link again before it is unblocked on the other side, it will block the
link to that other side. The same happens on the other side when it
unblocks the link. In that scenario, the link never recovers on its own.
To fix this, allow restarting authentication even if the link is in
blocked state, but don't initiate the attempt until the blocked period
is over. This reverts commit 09d96de09e ("mesh: Drop Authentication
frames from BLOCKED STA").

The DTIM information in the per-STA profile is set incorrectly. The DTIM
period is set in the LSB octet of the DTIM Info subfield (2 octets),
which is intended for the DTIM count.
Fix this by setting the DTIM period and DTIM count information properly
to the MSB and LSB octets of the DTIM Info subfield, respectively.

When we are configuring automatic channel selection, we are not able to
switch to a given DFS channel because when we are trying to move to a
DFS channel, the interface is disabled and enabled again. When the
interface is disabled and enabled we are setting iface's freq and
channel to 0 in setup_interface2() in case ACS is enabled, and now we
don't know to which channel we were trying to move. Now ACS will run and
the interface will be up in the channel that is suitable.
To fix this issue add a flag named is_ch_switch_dfs to check if the
channel switch request is for a DFS channel and we can use this in
setup_interface2() to decide whther we have to set iface's freq and
channel to 0 or not. This way iface's freq and channel will retain the
values while channel switching to a DFS channel when ACS is enabled.

Add a new flag radar_detected which is used in the following cases
when setting up a link on a DFS channel while the interface is not yet
enabled:
1. DFS link received CAC start event
2. If no radar detected, link setup succeeeds after CAC end
event is received. Else go to 3.
3. Radar detected on this link -> set radar_detected bit
4. CAC end received for the current freq -> Do not setup interface
as radar already detected. Clear radar_detected bit.
5. The driver sends channel switch event to switch to another channel
a. Switch to another DFS channel -> go to 1
b. Switch to non-DFS channel -> proceed to set up interface
Or when receiving a CAC start event when the interface is already set up:
1. DFS link already set up successfully
2. Radar detected on this link -> set radar_detected bit
a. Switch to DFS channel
a.1. CAC start -> clear radar_detected bit and partner RNR
a.2. If radar detected, go to 2.
a.3. CAC end -> clear radar_detected bit
a.4. Link enabled successfully
b. Switch to non-DFS channel
b.1 No op and the driver handles this

Link ID is more accurate to specify the BSS for a radar event in some
corner cases, e.g., when there is a radar detection event and the driver
then switches to another DFS channel. There will then be two events
coming from the driver (CAC start and channel switch complete). In case
the CAC-start event comes first, hostapd still stores the previous
frequency and cannot find the correct link by calling
nl80211_get_mld_link_by_freq() with the new frequency.
