ath12k just like ath11k [1] did not handle skb cleanup during idr
cleanup callback. Both ath12k_mac_vif_txmgmt_idr_remove() and
ath12k_mac_tx_mgmt_pending_free() performed idr cleanup and DMA
unmapping for skb but only ath12k_mac_tx_mgmt_pending_free() freed
skb. As a result, during vdev deletion a memory leak occurs.
Refactor all clean up steps into a new function. New function
ath12k_mac_tx_mgmt_free() creates a centralized area where idr
cleanup, DMA unmapping for skb and freeing skb is performed. Utilize
skb pointer given by idr_remove(), instead of passed as a function
argument because IDR will be protected by locking. This will prevent
concurrent modification of the same IDR.
Now ath12k_mac_tx_mgmt_pending_free() and
ath12k_mac_vif_txmgmt_idr_remove() call ath12k_mac_tx_mgmt_free().

Pull networking updates from Paolo Abeni:
"Core & protocols:
- Improve drop account scalability on NUMA hosts for RAW and UDP
sockets and the backlog, almost doubling the Pps capacity under DoS
- Optimize the UDP RX performance under stress, reducing contention,
revisiting the binary layout of the involved data structs and
implementing NUMA-aware locking. This improves UDP RX performance
by an additional 50%, even more under extreme conditions
- Add support for PSP encryption of TCP connections; this mechanism
has some similarities with IPsec and TLS, but offers superior HW
offloads capabilities
- Ongoing work to support Accurate ECN for TCP. AccECN allows more
than one congestion notification signal per RTT and is a building
block for Low Latency, Low Loss, and Scalable Throughput (L4S)
- Reorganize the TCP socket binary layout for data locality, reducing
the number of touched cachelines in the fastpath
- Refactor skb deferral free to better scale on large multi-NUMA
hosts, this improves TCP and UDP RX performances significantly on
such HW
- Increase the default socket memory buffer limits from 256K to 4M to
better fit modern link speeds
- Improve handling of setups with a large number of nexthop, making
dump operating scaling linearly and avoiding unneeded
synchronize_rcu() on delete
- Improve bridge handling of VLAN FDB, storing a single entry per
bridge instead of one entry per port; this makes the dump order of
magnitude faster on large switches
- Restore IP ID correctly for encapsulated packets at GSO
segmentation time, allowing GRO to merge packets in more scenarios
- Improve netfilter matching performance on large sets
- Improve MPTCP receive path performance by leveraging recently
introduced core infrastructure (skb deferral free) and adopting
recent TCP autotuning changes
- Allow bridges to redirect to a backup port when the bridge port is
administratively down
- Introduce MPTCP 'laminar' endpoint that con be used only once per
connection and simplify common MPTCP setups
- Add RCU safety to dst->dev, closing a lot of possible races
- A significant crypto library API for SCTP, MPTCP and IPv6 SR,
reducing code duplication
- Supports pulling data from an skb frag into the linear area of an
XDP buffer
Things we sprinkled into general kernel code:
- Generate netlink documentation from YAML using an integrated YAML
parser
Driver API:

easily building DevMem-enabled drivers with a unified XDP/skbs
datapath
- Add a new dedicated ethtool callback enabling drivers to provide
the number of RX rings directly, improving efficiency and clarity
in RX ring queries and RSS configuration

Currently, the QMI interface only works on little endian systems due to how
it encodes and decodes data. Most QMI related data structures do not use
endian specific types and are already defined in CPU native order. The
ath12k specific QMI structs are an exception: they use partially endian
specific types, which prevents the QMI interface from being extended to
support big endian systems.
Update the two affected ath12k QMI structs to use CPU order types instead.
This is required because the QMI interface is being extended to support big
endian system, and that support depends on QMI data structures being
defined in CPU native order.
This change:
* preserves compatibility with existing kernels, which only support little
endian system
* enables future support for big endian systems
* aligns ath12k QMI handling with the general QMI design

During stress test scenarios, when the REO command ring becomes full,
the RX queue update command issued during peer deletion fails due to
insufficient space. In response, the host performs a dma_unmap and
frees the associated memory. However, the hardware still retains a
reference to the same memory address. If the kernel later reallocates
this address, unaware that the hardware is still using it, it can
lead to memory corruption-since the host might access or modify
memory that is still actively referenced by the hardware.
Implement a retry mechanism for the HAL_REO_CMD_UPDATE_RX_QUEUE
command during TID deletion to prevent memory corruption. Introduce
a new list, reo_cmd_update_rx_queue_list, in the struct ath12k_dp to
track pending RX queue updates. Protect this list with
reo_rxq_flush_lock, which also ensures synchronized access to
reo_cmd_cache_flush_list. Defer memory release until hardware
confirms the virtual address is no longer in use, avoiding immediate
deallocation on command failure. Release memory for pending RX queue
updates via ath12k_dp_rx_reo_cmd_list_cleanup() on system reset
if hardware confirmation is not received.

In ath12k_dp_mon_rx_deliver_msdu(), peer lookup fails because
rxcb->peer_id is not updated with a valid value. This is expected
in monitor mode, where RX frames bypass the regular RX
descriptor path that typically sets rxcb->peer_id.
As a result, the peer is NULL, and link_id and link_valid fields
in the RX status are not populated. This leads to a WARN_ON in
mac80211 when it receives data frame from an associated station
with invalid link_id.
Fix this potential issue by using ppduinfo->peer_id, which holds
the correct peer id for the received frame. This ensures that the
peer is correctly found and the associated link metadata is updated
accordingly.

Currently, ath12k_mac_handle_beacon_miss() does not handle the beacon
miss for the MLO case.
In MLO scenarios, the host fails to process the beacon miss because the
vdev_id comparison in ath12k_mac_handle_beacon_miss_iter() does not match.
This mismatch occurs since arvif always points to ahvif->deflink, which may
not correspond to the actual vdev_id associated with the event.
Fix this by retrieving arvif from vdev_id instead of ahvif->deflink which
will work for both MLO and Non-MLO case.
Also refactor the ath12k_mac_handle_beacon_miss(), by passing arvif
directly instead of vdev_id and remove ath12k_mac_handle_beacon_miss_iter()
which is no longer needed.
ath12k_mac_handle_beacon_miss() is called from ath12k_roam_event() for WCN
chipsets and ath12k_peer_sta_kickout_event() for QCN chipsets.
So, refactor the ath12k_roam_event() to pass arvif instead vdev_id to the
ath12k_mac_handle_beacon_miss() function to align with the
ath12k_peer_sta_kickout_event() and change the rcu_read_lock() to
guard(rcu)() in the same function ath12k_roam_event().

Currently, when the non-AP STA connected to the AP STA, and the AP STA goes
down or becomes inactive without indication, firmware detects the beacon
miss and sends the WMI event WMI_PEER_STA_KICKOUT_EVENTID with reason as
INACTIVITY. The host driver handles this event as low ACK and reports it to
the mac80211 driver.
However, the expectation is that non-AP STA should be disconnected from
AP STA instantly once it receives the STA kickout event with reason of
inactivity.
Trigger a disconnect from AP STA through beacon miss handling upon
receiving non-AP STA peer kickout event with reason code inactivity.
Replace the helper function ath12k_mac_get_ar_by_vdev_id() with
ath12k_mac_get_arvif_by_vdev_id() due to the following reasons.
1. Check the station VIF type for handling the beacon miss.
2. Retrieve the proper ar from the arvif by checking the vdev_id with
vdev_map and link_map lookup which is needed for the MLO case in the

Currently, command “iw wlan0 station dump” does not show per-chain signal

This is because ath12k does not handle the num_per_chain_rssi and
rssi_avg_beacon reported by firmware to ath12k.
To address this, update ath12k to send WMI_REQUEST_STATS_CMDID with the
flag WMI_REQUEST_RSSI_PER_CHAIN_STAT to the firmware. Then, add logic to
handle num_per_chain_rssi and rssi_avg_beacon in the
ath12k_wmi_tlv_fw_stats_parse(), and assign the resulting per-chain signal
strength to the chain_signal of struct station_info.

There are two rings involved in the Copy Engine (CE) receive path
handling, the CE status (STS) ring and the CE destination (DST) ring.
Each time CE hardware needs to send an event (e.g. WMI event) to host,
CE hardware finds a buffer (to which the tail pointer (TP) points) in
DST ring and fills it with payload, then hardware fills meta data in
STS ring and fires interrupt to host. Please note the TP of DST ring is
expected to be advanced by CE hardware before interrupting host. While
handling the interrupt, host finds that DST ring buffers are used hence
increases rx_buf_needed to record the number of buffers to be replenished.
Note before that, host compares TP and head pointer (HP) of DST ring to
see if there is available space. Normally rx_buf_needed simply equals
available space. But sometimes CE hardware doesn't (for whatever reason)
update TP timely, making the comparison fails, then enqueue is cancelled
and a warning is logged.
However even enqueue fails this time, rx_buf_needed still records the
numbers of needed buffers. Later when TP gets updated correctly, the
missing buffer will be eventually replenished. And there is no doubt on
the late update, it always comes (or lots of such warnings should be seen).
Since this won't cause any functional issue, downgrade logging level to
avoid misleading.
Compile tested only.

Currently, ath12k_dp_rx_h_ppdu() determines the band and frequency
based on the channel number and center frequency from the RX descriptor's
PHY metadata. However, in rare cases, it is observed that frequency
retrieved from the metadata may be invalid or unexpected especially for
6 GHz frames.
This can result in a NULL sband, which prevents proper frequency assignment
in rx_status and potentially leading to incorrect RX packet classification.
To fix this potential issue, add a fallback mechanism that uses
ar->rx_channel to populate the band and frequency when the derived
sband is invalid or missing.

Currently, host fetches combined rssi from rssi_comb in struct
hal_rx_phyrx_rssi_legacy_info.
rssi_comb is 8th to 15th bits of the second to last variable.
rssi_comb_ppdu is the 0th to 7th of the last variable.
When bandwidth = 20MHz, rssi_comb = rssi_comb_ppdu. But when bandwidth >
20MHz, rssi_comb < rssi_comb_ppdu because rssi_comb only includes power
of primary 20 MHz while rssi_comb_ppdu includes power of active
RUs/subchannels. So should fetch combined rssi from rssi_comb_ppdu.
Also related macro definitions are too long, rename them.

In ath12k_mac_parse_tx_pwr_env(), for the non-PSD case num_pwr_levels is
limited by ATH12K_NUM_PWR_LEVELS which is 16:
if (tpc_info->num_pwr_levels > ATH12K_NUM_PWR_LEVELS)
tpc_info->num_pwr_levels = ATH12K_NUM_PWR_LEVELS;
Then it is used to iterate entries in local_non_psd->power[] and
reg_non_psd->power[]:
for (i = 0; i < tpc_info->num_pwr_levels; i++) {
tpc_info->tpe[i] = min(local_non_psd->power[i],
reg_non_psd->power[i]) / 2;
Since the two array are of size 5, Smatch warns:
drivers/net/wireless/ath/ath12k/mac.c:9812
ath12k_mac_parse_tx_pwr_env() error: buffer overflow 'local_non_psd->power' 5 <= 15
drivers/net/wireless/ath/ath12k/mac.c:9812
ath12k_mac_parse_tx_pwr_env() error: buffer overflow 'reg_non_psd->power' 5 <= 15
This is a false positive as there is already implicit limitation:
tpc_info->num_pwr_levels = max(local_non_psd->count,
reg_non_psd->count);
meaning it won't exceed 5.
However, to make robot happy, add explicit limit there.
Also add the same to the PSD case, although no warning due to
ATH12K_NUM_PWR_LEVELS equals IEEE80211_TPE_PSD_ENTRIES_320MHZ.

Currently, at the end of ath12k_mac_fill_reg_tpc_info(), the
reg_tpc_info struct is populated, including the following:
reg_tpc_info->is_psd_power = is_psd_power;
reg_tpc_info->eirp_power = eirp_power;
Kernel test robot complains on uninitialized symbol:
drivers/net/wireless/ath/ath12k/mac.c:10069
ath12k_mac_fill_reg_tpc_info() error: uninitialized symbol 'eirp_power'
This is because there are some code paths that never set eirp_power, so
the assignment of reg_tpc_info->eirp_power can come from an
uninitialized variable. Functionally this is OK since the eirp_power
only has meaning when is_psd_power is true, and all code paths which set
is_psd_power to true also set eirp_power. However, to keep the robot
happy, always initialize eirp_power before use.

Currently, command to set RTS threshold makes changes to the threshold of
all radios in the multi-radio wiphy. But each radio in a multi-radio wiphy
can have different RTS threshold requirements.
To support this requirement, use the index of radio for which the RTS
threshold needs to be changed from mac80211 - radio_idx. Based on the value
passed, set the RTS threshold value for the corresponding radios. Following
are the possible values of radio_idx and the corresponding behavior in
multi-radio wiphys:
1. radio_idx is -1: consider RTS threshold as a global parameter, i.e.,
make changes to all the radios in a wiphy. If setting RTS threshold
fails for any radio, then the previous RTS threshold values of
respective radios will be restored.
2. radio_idx denotes a specific radio: make changes in RTS threshold to
that radio alone.
3. radio_idx is any other number: report it as an invalid number.
In case of single-radio wiphys, continue with the existing behavior, i.e.,
set the passed RTS threshold value to the radio present.

Currently, if any error occurs during ath12k_dp_rx_peer_tid_setup(),
the tid value is already incremented, even though the corresponding
TID is not actually allocated. Proceed to
ath12k_dp_rx_peer_tid_delete() starting from unallocated tid,
which might leads to freeing unallocated TID and cause potential
crash or out-of-bounds access.
Hence, fix by correctly decrementing tid before cleanup to match only
the successfully allocated TIDs.
Also, remove tid-- from failure case of ath12k_dp_rx_peer_frag_setup(),
as decrementing the tid before cleanup in loop will take care of this.

to support 2 channels concurrently, making AP mode not working on DFS
channels [1].
Revert portions of that commit to bring DFS back, and add a new

MAC80211 restrict works on each individual combination, but does not care
about them as a whole, as far as DFS is concerned.
This change applies to WCN7850 only, other chips are not affected.

works correctly to report transmission status to mac80211, as
it retrieves station information using sta_info_get_by_addrs().

regardless of the operating mode (Mission or FTM).
Firmware expects additional software information (like peer ID, vdev
ID, and link ID) in Tx packets when HTT_TCL_METADATA_VER_V2 is set.
However, in FTM (Factory Test Mode) mode, no vdev is created on the
host side (this is expected). As a result, the firmware fails to find
the expected vdev during packet processing and ends up dropping
packets.
To fix this, send HTT_TCL_METADATA_VER_V1 in FTM mode because FTM

A multi-link client can use any link for transmissions. It can decide to
put one link in power save mode for longer periods while listening on the
other links as per MLD listen interval. Unicast management frames sent to
that link station might get dropped if that link station is in power save
mode or inactive. In such cases, firmware can take decision on which link
to use.
Allow the firmware to decide on which link management frame should be
sent on, by filling the hardware link with maximum value of u32, so that
the firmware will not have a specific link to transmit data on and so
the management frames will be link agnostic. For QCN devices, all action
frames are marked as link agnostic. For WCN devices, if the device is
configured as an AP, then all frames other than probe response frames,
authentication frames, association response frames, re-association response
frames and ADDBA response frames are marked as link agnostic and if the
device is configured as a station, then all frames other than probe request
frames, authentication frames, de-authentication frames and ADDBA response
frames are marked as link agnostic.
