570eec3d40 wifi: ath11k: Relocate the func ath11k_mac_bitrate_mask_num_ht_rates() and change hweight16 to hweight8
Relocate the function ath11k_mac_bitrate_mask_num_ht_rates() definition
to call this function from other functions which helps to avoid the
compilation error (function not defined).

ht_mcs[] is 1 byte array and it is enough to use hweight8() instead
of hweight16(). Hence, fixed the same.

Tested on: Compile tested only.

1fd2c3f93c wifi: ath12k: increase vdev setup timeout
When vdev start/stop happens, response from firmware is received with delay
and hence there is a timeout before VDEV can be up/down.
Also, with maximum peers connected and when vdev stop occurs, firmware
will take time to clean up all the peers and vap queues.
In such cases as well, vdev start/stop response is sent by firmware with delay.

Increase the vdev setup timeout as recommended by firmware team.

cb9bea773c wifi: ath11k: refactor vif parameter configurations
Security parameters for each non-transmitting profile can be
different when MBSSID is enabled and this information is included
in the MBSSID element in the Beacon frame. Current implementation
to set rsnie_present and wpaie_present does not parse this element
hence it applies only to the transmitting interface.

Move the code to a separate function to make additions for
non-transmitting interfaces cleaner.

ath11k_wmi_fw_stats_num_vdevs() and ath11k_wmi_fw_stats_num_bcn() really
look the same as list_count_nodes(), so use the latter instead of hand
writing it.

The first ones use list_for_each_entry() and the other list_for_each(), but
they both count the number of nodes in the list.

While at it, also remove to prototypes of non-existent functions.
Based on the names and prototypes, it is likely that they should be
equivalent to list_count_nodes().

b719ebc37a wifi: ath10k: Serialize wake_tx_queue ops
Serialize the ath10k implementation of the wake_tx_queue ops.
ath10k_mac_op_wake_tx_queue() must not run concurrent since it's using
ieee80211_txq_schedule_start().

The intend of this patch is to sort out an issue discovered in the discussion
referred to by the Link tag.

I can't test it with real hardware and thus just implemented the per-ac queue
lock Felix suggested. One obvious alternative to the per-ac lock would be to
bring back the txqs_lock commit bb2edb7335 ("ath10k: migrate to mac80211 txq
scheduling") dropped.

e995f3f602 wifi: ath12k: fix potential wmi_mgmt_tx_queue race condition
During stress test with maximum VAPs and peer connected, below warning
is seen:

[ 1079.110967] ath12k_pci 0004:01:00.0: mgmt tx queue is full
[ 1079.117708] ath12k_pci 0004:01:00.0: failed to queue management frame -28

[ 1079.135641] ath12k_pci 0004:01:00.0: mgmt tx queue is full

This is caused by potential race condition while accessing skb_queue_len().
When ath12k_mgmt_over_wmi_tx_work() and ath12k_mac_mgmt_tx() is called concurrently,
then skb_queue_len() might fetch list length which is modified by skb_queue_tail()
or skb_dequeue().

Replace skb_queue_len() with skb_queue_len_lockless() which will
prevent concurrent modified access using READ_ONCE(). And also use '>=',
in case we queue a few SKBs simultaneously.

5189a8dba8 wifi: ath12k: add wait operation for tx management packets for flush from mac80211
Transmission of management packets are done in a work queue. Sometimes
the workqueue does not finish Tx immediately, then it lead after the next
step of vdev delete finished, it start to send the management packet to
firmware and lead firmware crash.

ieee80211_set_disassoc() have logic of ieee80211_flush_queues() after
it send_deauth_disassoc() to ath12k, its purpose is make sure the
deauth was actually sent, so it need to change ath12k to match the
purpose of mac80211.

To address these issues wait for Tx management as well as Tx data packets.

For the reasons also described in commit b383e8abed ("wifi: ath9k: avoid
uninit memory read in ath9k_htc_rx_msg()"), ath9k_htc_rx_msg() should
validate pkt_len before accessing the SKB.

For example, the obtained SKB may have been badly constructed with
pkt_len = 8. In this case, the SKB can only contain a valid htc_frame_hdr
but after being processed in ath9k_htc_rx_msg() and passed to
ath9k_wmi_ctrl_rx() endpoint RX handler, it is expected to have a WMI
command header which should be located inside its data payload.

Implement sanity checking inside ath9k_wmi_ctrl_rx(). Otherwise, uninit
memory can be referenced.

Pull networking updates from Paolo Abeni:
 "Core:

   - Introduce a config option to tweak MAX_SKB_FRAGS. Increasing the
     default value allows for better BIG TCP performances

   - Reduce compound page head access for zero-copy data transfers

   - RPS/RFS improvements, avoiding unneeded NET_RX_SOFTIRQ when
     possible

   - Threaded NAPI improvements, adding defer skb free support and
     unneeded softirq avoidance

   - Address dst_entry reference count scalability issues, via false
     sharing avoidance and optimize refcount tracking

   - Add lockless accesses annotation to sk_err[_soft]

   - Optimize again the skb struct layout

   - Extends the skb drop reasons to make it usable by multiple
     subsystems

   - Better const qualifier awareness for socket casts

  BPF:

   - Add skb and XDP typed dynptrs which allow BPF programs for more
     ergonomic and less brittle iteration through data and
     variable-sized accesses

   - Add a new BPF netfilter program type and minimal support to hook
     BPF programs to netfilter hooks such as prerouting or forward

   - Add more precise memory usage reporting for all BPF map types

   - Adds support for using {FOU,GUE} encap with an ipip device
     operating in collect_md mode and add a set of BPF kfuncs for
     controlling encap params

   - Allow BPF programs to detect at load time whether a particular
     kfunc exists or not, and also add support for this in light
     skeleton

   - Bigger batch of BPF verifier improvements to prepare for upcoming
     BPF open-coded iterators allowing for less restrictive looping
     capabilities

   - Rework RCU enforcement in the verifier, add kptr_rcu and enforce
     BPF programs to NULL-check before passing such pointers into kfunc

   - Add support for kptrs in percpu hashmaps, percpu LRU hashmaps and
     in local storage maps

   - Enable RCU semantics for task BPF kptrs and allow referenced kptr
     tasks to be stored in BPF maps

   - Add support for refcounted local kptrs to the verifier for allowing
     shared ownership, useful for adding a node to both the BPF list and
     rbtree

   - Add BPF verifier support for ST instructions in
     convert_ctx_access() which will help new -mcpu=v4 clang flag to
     start emitting them

   - Add ARM32 USDT support to libbpf

   - Improve bpftool's visual program dump which produces the control
     flow graph in a DOT format by adding C source inline annotations

  Protocols:

   - IPv4: Allow adding to IPv4 address a 'protocol' tag. Such value
     indicates the provenance of the IP address

   - IPv6: optimize route lookup, dropping unneeded R/W lock acquisition

   - Add the handshake upcall mechanism, allowing the user-space to
     implement generic TLS handshake on kernel's behalf

   - Bridge: support per-{Port, VLAN} neighbor suppression, increasing
     resilience to nodes failures

   - SCTP: add support for Fair Capacity and Weighted Fair Queueing
     schedulers

   - MPTCP: delay first subflow allocation up to its first usage. This
     will allow for later better LSM interaction

   - xfrm: Remove inner/outer modes from input/output path. These are
     not needed anymore

   - WiFi:
      - reduced neighbor report (RNR) handling for AP mode
      - HW timestamping support
      - support for randomized auth/deauth TA for PASN privacy
      - per-link debugfs for multi-link
      - TC offload support for mac80211 drivers
      - mac80211 mesh fast-xmit and fast-rx support
      - enable Wi-Fi 7 (EHT) mesh support

  Netfilter:

   - Add nf_tables 'brouting' support, to force a packet to be routed
     instead of being bridged

   - Update bridge netfilter and ovs conntrack helpers to handle IPv6
     Jumbo packets properly, i.e. fetch the packet length from
     hop-by-hop extension header. This is needed for BIT TCP support

   - The iptables 32bit compat interface isn't compiled in by default
     anymore

   - Move ip(6)tables builtin icmp matches to the udptcp one. This has
     the advantage that icmp/icmpv6 match doesn't load the
     iptables/ip6tables modules anymore when iptables-nft is used

   - Extended netlink error report for netdevice in flowtables and
     netdev/chains. Allow for incrementally add/delete devices to netdev
     basechain. Allow to create netdev chain without device

  Driver API:

   - Remove redundant Device Control Error Reporting Enable, as PCI core
     has already error reporting enabled at enumeration time

   - Move Multicast DB netlink handlers to core, allowing devices other
     then bridge to use them

   - Allow the page_pool to directly recycle the pages from safely
     localized NAPI

   - Implement lockless TX queue stop/wake combo macros, allowing for
     further code de-duplication and sanitization

   - Add YNL support for user headers and struct attrs

   - Add partial YNL specification for devlink

   - Add partial YNL specification for ethtool

   - Add tc-mqprio and tc-taprio support for preemptible traffic classes

   - Add tx push buf len param to ethtool, specifies the maximum number
     of bytes of a transmitted packet a driver can push directly to the
     underlying device

   - Add basic LED support for switch/phy

   - Add NAPI documentation, stop relaying on external links

   - Convert dsa_master_ioctl() to netdev notifier. This is a
     preparatory work to make the hardware timestamping layer selectable
     by user space

   - Add transceiver support and improve the error messages for CAN-FD
     controllers

e671fb86ec wifi: ath12k: send WMI_PEER_REORDER_QUEUE_SETUP_CMDID when ADDBA session starts
Low receive throughput is seen on WCN7850 because ADDBA related
parameters are not updated to firmware when receive ADDBA session starts.

Fix it by sending WMI_PEER_REORDER_QUEUE_SETUP_CMDID again to firmware
to update the ADDBA related parameters for chips which have false
reoq_lut_support in hw_params. For chips which have true reoq_lut_support
in hw_params don't need this command to send to firmware.

Currently the CNSS (Connectivity Subsystem) QMI feature is assigned to

qmi_wlanfw_host_cap_req_msg_v01 request.

0f2a4af27b wifi: ath9k: Don't mark channelmap stack variable read-only in ath9k_mci_update_wlan_channels()
This partially reverts commit e161d4b60a.

Turns out the channelmap variable is not actually read-only, it's modified
through the MCI_GPM_CLR_CHANNEL_BIT() macro further down in the function,
so making it read-only causes page faults when that code is hit.

f9fff67d2d wifi: ath11k: Fix SKB corruption in REO destination ring
While running traffics for a long time, randomly an RX descriptor
filled with value "0" from REO destination ring is received.
This descriptor which is invalid causes the wrong SKB (SKB stored in
the IDR lookup with buffer id "0") to be fetched which in turn
causes SKB memory corruption issue and the same leads to crash
after some time.

Changed the start id for idr allocation to "1" and the buffer id "0"
is reserved for error validation. Introduced Sanity check to validate
the descriptor, before processing the SKB.

Crash Signature :

93a91f40c2 wifi: ath11k: fix double free of peer rx_tid during reo cmd failure
Peer rx_tid is locally copied thrice during peer_rx_tid_cleanup to
send REO_CMD_UPDATE_RX_QUEUE followed by REO_CMD_FLUSH_CACHE to flush
all aged REO descriptors from HW cache.

When sending REO_CMD_FLUSH_CACHE fails, we do dma unmap of already
mapped rx_tid->vaddr and free it. This is not checked during
reo_cmd_list_cleanup() and dp_reo_cmd_free() before trying to free and
unmap again.

Fix this by setting rx_tid->vaddr NULL in rx tid delete and also
wherever freeing it to check in reo_cmd_list_cleanup() and
reo_cmd_free() before trying to free again.

e04e4b6e01 wifi: ath9k: fix per-packet TX-power cap for TPC
Fix incorrect usage of plain rate_idx as index into the max (power) per
rate lookup table.

For transmit power control (TPC), the ath9k driver maintains internal
tables (in struct ath_hw) to store the max allowed power level per rate.
They are used to limit a given TX-power according to regulatory and user
limits in the TX-path per packet. The tables are filled in a predefined
order, starting with values for CCK + OFDM rates and followed by the
values for MCS rates. Thus, the maximum power levels for MCS do not
start at index 0 in the table but are shifted by a fixed value.

The TX-power limiting in ath_get_rate_txpower currently does not apply
this shift, thus retrieves the incorrect maximum power level for a given
rate. In particular for MCS rates, the maximum power levels for CCK/OFDM
rates were used, e.g. maximum power for OFDM 0 was used for MCS 0. If
STBC is used, the power is mostly limited to 0 because the STBC table
is zeroed for legacy CCK/OFDM rates. Encountered this during testing of
our work-in-progress TPC per packet for ath9k.
This only has an effect when TPC is enabled in ath9k (tpc_enabled in
struct ath_hw) which defaults to false. In this case it has a
significant impact on the used TX-power, throughput + RSSI. Otherwise
the affected code is just skipped and TX-power is limited with the
hardware registers only. This patch fixes this table lookup.

Tested on OpenWrt (kernel 5.15.98, but backported ath9k driver) with
small desk setup using ath9k chips AR9280 and AR9580. Cap of TX-power is
working properly for all rates now, throughput and RSSI as expected,
equal to as if TPC was disabled.
Compile-tested with latest 6.3 kernel + allyesconfig.

When max virtual ap interfaces are configured in all the bands with

In this certain scenario, a fragmented packet is received for
self peer, for which rx_tid and rx_frags are not initialized in

rx_frag list is uninitialised and when we walk in
ath11k_dp_rx_h_sort_frags, skb null leads to exception.

To address this, before processing received fragments we check
dp_setup_done flag is set to ensure that peer has completed its
dp peer setup for fragment queue, else ignore processing the
fragments.

Firmwares advertising the support of triggering 11d algorithm on the

WMI_11D_SCAN_START_CMDID before sending WMI_START_SCAN_CMDID.
Triggering 11d algorithm on the scan results of a normal scan helps
in completely avoiding a separate 11d scan for determining regdomain.
This indirectly helps in speeding up connections on station
interfaces on the chipsets supporting 11D scan.

To enable this feature, send WMI_11D_SCAN_START_CMDID just before
sending WMI_START_SCAN_CMDID if the firmware advertises
WMI_TLV_SERVICE_SUPPORT_11D_FOR_HOST_SCAN service flag.
