It is a consequence of a race between the waiting and the signaling side
of the completion:
Waiting thread Completing thread
rtw89_core_tx_kick_off_and_wait()
rcu_assign_pointer(skb_data->wait, wait)
/* start waiting */
wait_for_completion_timeout()
rtw89_pci_tx_status()
rtw89_core_tx_wait_complete()
rcu_read_lock()
/* signals completion and
* proceeds further
*/
complete(&wait->completion)
rcu_read_unlock()
...
/* frees skb_data */
ieee80211_tx_status_ni()
/* returns (exit status doesn't matter) */
wait_for_completion_timeout()
...
/* accesses the already freed skb_data */
rcu_assign_pointer(skb_data->wait, NULL)
The completing side might proceed and free the underlying skb even before
the waiting side is fully awoken and run to execution. Actually the race
happens regardless of wait_for_completion_timeout() exit status, e.g.
the waiting side may hit a timeout and the concurrent completing side is
still able to free the skb.
Skbs which are sent by rtw89_core_tx_kick_off_and_wait() are owned by the
driver. They don't come from core ieee80211 stack so no need to pass them
to ieee80211_tx_status_ni() on completing side.
Introduce a work function which will act as a garbage collector for
rtw89_tx_wait_info objects and the associated skbs. Thus no potentially
heavy locks are required on the completing side.

When buf_len is not 4-byte aligned in ath12k_wmi_mgmt_send(), the

This issue was observed when running 'iw wlanx set power_save off/on'
in MLO station mode, which triggers the sending of an SMPS action frame
with a length of 27 bytes to the AP. To resolve the misalignment, use
buf_len_aligned instead of buf_len when constructing the WMI TLV header.

During GTK rekey, mac80211 issues a clear key (if the old key exists)
followed by an install key operation in the same context. This causes
ath11k to send two WMI commands in quick succession: one to clear the
old key and another to install the new key in the same slot.
Under certain conditions—especially under high load or time sensitive
scenarios, firmware may process these commands asynchronously in a way
that firmware assumes the key is cleared whereas hardware has a valid key.
This inconsistency between hardware and firmware leads to group addressed
packet drops. Only setting the same key again can restore a valid key in
firmware and allow packets to be transmitted.
This issue remained latent because the host's clear key commands were
not effective in firmware until commit 436a4e8865 ("ath11k: clear the
keys properly via DISABLE_KEY"). That commit enabled the host to
explicitly clear group keys, which inadvertently exposed the race.
To mitigate this, restrict group key clearing across all modes (AP, STA,
MESH). During rekey, the new key can simply be set on top of the previous
one, avoiding the need for a clear followed by a set.
However, in AP mode specifically, permit group key clearing when no
stations are associated. This exception supports transitions from secure
modes (e.g., WPA2/WPA3) to open mode, during which all associated peers
are removed and the group key is cleared as part of the transition.
Add a per-BSS station counter to track the presence of stations during
set key operations. Also add a reset_group_keys flag to track the key
re-installation state and avoid repeated installation of the same key
when the number of connected stations transitions to non-zero within a
rekey period.
Additionally, for AP and Mesh modes, when the first station associates,
reinstall the same group key that was last set. This ensures that the
firmware recovers from any race that may have occurred during a previous
key clear when no stations were associated.
This change ensures that key clearing is permitted only when no clients
are connected, avoiding packet loss while enabling dynamic security mode
transitions.

Currently, when updating EMLSR capabilities of a multi-link (ML) station,
only the EMLSR parameters (e.g., padding delay, transition delay, and
timeout) are sent to firmware. However, firmware also requires the
EMLSR support flag to be set in the MLO flags of the peer assoc WMI
command to properly handle EML operating mode notification frames.
Set the ATH12K_WMI_FLAG_MLO_EMLSR_SUPPORT flag in the peer assoc WMI
command when the ML station is EMLSR-capable, so that the firmware can
respond to EHT EML action frames from associated stations.

The adapter->chan_stats[] array is initialized in
mwifiex_init_channel_scan_gap() with vmalloc(), which doesn't zero out
memory. The array is filled in mwifiex_update_chan_statistics()
and then the user can query the data in mwifiex_cfg80211_dump_survey().
There are two potential issues here. What if the user calls
mwifiex_cfg80211_dump_survey() before the data has been filled in.
Also the mwifiex_update_chan_statistics() function doesn't necessarily
initialize the whole array. Since the array was not initialized at
the start that could result in an information leak.
Also this array is pretty small. It's a maximum of 900 bytes so it's
more appropriate to use kcalloc() instead vmalloc().

When station mode, don't disconnect when we get
channel switch from AP to DFS channel. Most APs
send CSA request after pass background CAC. In other
case we should disconnect after detect beacon miss.
Without patch when we get CSA to DFS channel get:
"kernel: wlo1: preparing for channel switch failed, disconnecting"

The brcmf_btcoex_detach() only shuts down the btcoex timer, if the
flag timer_on is false. However, the brcmf_btcoex_timerfunc(), which
runs as timer handler, sets timer_on to false. This creates critical
race conditions:
1.If brcmf_btcoex_detach() is called while brcmf_btcoex_timerfunc()
is executing, it may observe timer_on as false and skip the call to
timer_shutdown_sync().
2.The brcmf_btcoex_timerfunc() may then reschedule the brcmf_btcoex_info
worker after the cancel_work_sync() has been executed, resulting in
use-after-free bugs.
The use-after-free bugs occur in two distinct scenarios, depending on
the timing of when the brcmf_btcoex_info struct is freed relative to
the execution of its worker thread.
Scenario 1: Freed before the worker is scheduled
The brcmf_btcoex_info is deallocated before the worker is scheduled.
A race condition can occur when schedule_work(&bt_local->work) is
called after the target memory has been freed. The sequence of events
is detailed below:
CPU0 | CPU1
brcmf_btcoex_detach | brcmf_btcoex_timerfunc
| bt_local->timer_on = false;
if (cfg->btcoex->timer_on) |
... |
cancel_work_sync(); |
... |
kfree(cfg->btcoex); // FREE |
| schedule_work(&bt_local->work); // USE
Scenario 2: Freed after the worker is scheduled
The brcmf_btcoex_info is freed after the worker has been scheduled
but before or during its execution. In this case, statements within
the brcmf_btcoex_handler() — such as the container_of macro and
subsequent dereferences of the brcmf_btcoex_info object will cause
a use-after-free access. The following timeline illustrates this
scenario:
CPU0 | CPU1
brcmf_btcoex_detach | brcmf_btcoex_timerfunc
| bt_local->timer_on = false;
if (cfg->btcoex->timer_on) |
... |
cancel_work_sync(); |
... | schedule_work(); // Reschedule
|
kfree(cfg->btcoex); // FREE | brcmf_btcoex_handler() // Worker
/* | btci = container_of(....); // USE
The kfree() above could | ...
also occur at any point | btci-> // USE
during the worker's execution|
*/ |
To resolve the race conditions, drop the conditional check and call
timer_shutdown_sync() directly. It can deactivate the timer reliably,
regardless of its current state. Once stopped, the timer_on state is
then set to false.

Core & protocols
----------------
- Wrap datapath globals into net_aligned_data, to avoid false sharing.
- Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container).
- Add SO_INQ and SCM_INQ support to AF_UNIX.
- Add SIOCINQ support to AF_VSOCK.
- Add TCP_MAXSEG sockopt to MPTCP.
- Add IPv6 force_forwarding sysctl to enable forwarding per interface.
- Make TCP validation of whether packet fully fits in the receive
window and the rcv_buf more strict. With increased use of HW
aggregation a single "packet" can be multiple 100s of kB.
- Add MSG_MORE flag to optimize large TCP transmissions via sockmap,
improves latency up to 33% for sockmap users.
- Convert TCP send queue handling from tasklet to BH workque.
- Improve BPF iteration over TCP sockets to see each socket exactly once.
- Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code.
- Support enabling kernel threads for NAPI processing on per-NAPI
instance basis rather than a whole device. Fully stop the kernel NAPI
thread when threaded NAPI gets disabled. Previously thread would stick
around until ifdown due to tricky synchronization.
- Allow multicast routing to take effect on locally-generated packets.
- Add output interface argument for End.X in segment routing.
- MCTP: add support for gateway routing, improve bind() handling.
- Don't require rtnl_lock when fetching an IPv6 neighbor over Netlink.
- Add a new neighbor flag ("extern_valid"), which cedes refresh
responsibilities to userspace. This is needed for EVPN multi-homing
where a neighbor entry for a multi-homed host needs to be synced
across all the VTEPs among which the host is multi-homed.
- Support NUD_PERMANENT for proxy neighbor entries.
- Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM.
- Add sequence numbers to netconsole messages. Unregister netconsole's
console when all net targets are removed. Code refactoring.
Add a number of selftests.
- Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol
should be used for an inbound SA lookup.
- Support inspecting ref_tracker state via DebugFS.
- Don't force bonding advertisement frames tx to ~333 ms boundaries.
Add broadcast_neighbor option to send ARP/ND on all bonded links.
- Allow providing upcall pid for the 'execute' command in openvswitch.
- Remove DCCP support from Netfilter's conntrack.
- Disallow multiple packet duplications in the queuing layer.
- Prevent use of deprecated iptables code on PREEMPT_RT.
Driver API
----------
- Support RSS and hashing configuration over ethtool Netlink.
- Add dedicated ethtool callbacks for getting and setting hashing fields.

Support providing clock reference and SYNC over separate DPLL
inputs.
- Support traffic classes in devlink rate API for bandwidth management.
- Remove rtnl_lock dependency from UDP tunnel port configuration.

...
Prepare for adding an enum type for NAPI threaded states by adding
netif_threaded_enable API. De-export the existing netif_set_threaded API
and only use it internally. Update existing drivers to use
netif_threaded_enable instead of the de-exported netif_set_threaded.
Note that dev_set_threaded used by mt76 debugfs file is unchanged.

To eliminate the use of struct page in page pool, the page pool users
should use netmem descriptor and APIs instead.
Make mt76 access ->pp through netmem_desc instead of page.
