16ecdab544 wifi: mac80211: reject TDLS operations when station is not associated
syzbot triggered a WARN in ieee80211_tdls_oper() by sending
NL80211_TDLS_ENABLE_LINK immediately after NL80211_CMD_CONNECT,
before association completed and without prior TDLS setup.

This left internal state like sdata->u.mgd.tdls_peer uninitialized,
leading to a WARN_ON() in code paths that assumed it was valid.

Reject the operation early if not in station mode or not associated.

81284e86bf wifi: brcmsmac: Remove const from tbl_ptr parameter in wlc_lcnphy_common_read_table()
A new warning in clang [1] complains that diq_start in
wlc_lcnphy_tx_iqlo_cal() is passed uninitialized as a const pointer to
wlc_lcnphy_common_read_table():

  drivers/net/wireless/broadcom/brcm80211/brcmsmac/phy/phy_lcn.c:2728:13: error: variable 'diq_start' is uninitialized when passed as a const pointer argument here [-Werror,-Wuninitialized-const-pointer]

The table pointer passed to wlc_lcnphy_common_read_table() should not be
considered constant, as wlc_phy_read_table() is ultimately going to
update it. Remove the const qualifier from the tbl_ptr to clear up the
warning.

1bc892d76a wifi: mac80211: extend connection monitoring for MLO
Currently, reset connection monitor (ieee80211_sta_reset_conn_monitor())
timer is handled only for non-AP non-MLD STA and do not support non-AP MLD
STA. The current implementation checks for the CSA active and update the
monitor timer with the timeout value of deflink and reset the timer based
on the deflink's timeout value else schedule the connection loss work when
the deflink is timed out and it won't work for the non-AP MLD STA.

Handle the reset connection monitor timer for non-AP MLD STA by updating
the monitor timer with the timeout value which is determined based on the
link that will expire last among all the links in MLO. If at least one link
has not timed out, the timer is updated accordingly with the latest timeout
value else schedule the connection loss work when all links have timed out.

Remove the MLO-related WARN_ON() checks in the beacon and connection
monitoring logic code paths as they support MLO now.

66e53e117f wifi: mac80211: extend beacon monitoring for MLO
Currently, reset beacon monitor (ieee80211_sta_reset_beacon_monitor())
timer is handled only for non-AP non-MLD STA and do not support non-AP MLD
STA. When the beacon loss occurs in non-AP MLD STA with the current
implementation, it is treated as a single link and the timer will reset
based on the timeout of the deflink, without checking all the links.

Check the CSA flags for all the links in the MLO and decide whether to
schedule the work queue for beacon loss. If any of the links has CSA
active, then beacon loss work is not scheduled.

Also, call the functions ieee80211_sta_reset_beacon_monitor() and
ieee80211_sta_reset_conn_monitor() from ieee80211_csa_switch_work() only
when all the links are CSA active.

4e1916dec9 wifi: mac80211: Add link iteration macro for link data with rcu_dereference
Currently, the existing macro for_each_link_data() uses sdata_dereference()
which requires the wiphy lock. This lock cannot be used in atomic or RCU
read-side contexts, such as in the RX path.

Introduce a new macro, for_each_link_data_rcu(), that iterates over link of
sdata using rcu_dereference(), making it safe to use in RCU contexts. This
allows callers to access link data without requiring the wiphy lock.

The macro takes into account the vif.valid_links bitmap and ensures only
valid links are accessed safely. Callers are responsible for ensuring that
rcu_read_lock() is held when using this macro.

f562f6a589 wifi: mac80211: fix macro scoping in for_each_link_data
The for_each_link_data() macro currently declares a local variable
__sdata directly, which could lead to compiler warnings or errors when
reused in the same function or within switch-case blocks due to variable
redefinition or invalid scoping.

To address this, restructure the macro to use an outer for-loop that runs
only once, allowing safe declaration of __sdata without polluting the outer
scope. This ensures compatibility with static analyzers.

No functional changes; this is purely a cleanup to improve macro hygiene.

765e98e918 wifi: cfg80211/mac80211: remove wrong scan request n_channels
This (partially) reverts commits
 - 838c7b8f1f ("wifi: nl80211: Avoid address calculations via out of bounds array indexing")
 - f1d3334d60 ("wifi: cfg80211: sme: init n_channels before channels[] access")
 - 82bbe02b25 ("wifi: mac80211: Set n_channels after allocating struct cfg80211_scan_request")

These commits all set the structure to be in an inconsistent
state, setting n_channels to some value before them actually
being filled in. That's fine for what the code does now, but
with the removal of __counted_by() in 444020f4bf ("wifi:
cfg80211: remove scan request n_channels counted_by") it's no
longer needed and it does leave a bit of a landmine there
since breaking out of some code to send the scan or something
would leave it wrong.

Remove the now superfluous n_channels settings.

Remove request batching support from crypto_engine, as there are no
drivers using this feature and it doesn't really work that well.

Instead of doing batching based on backlog, a more optimal approach
would be for the user to handle the batching (similar to how IPsec
can hook into GSO to get 64K of data each time or how block encryption
can use unit sizes much greater than 4K).

3d4df408ba crypto: qat - flush misc workqueue during device shutdown
Repeated loading and unloading of a device specific QAT driver, for
example qat_4xxx, in a tight loop can lead to a crash due to a
use-after-free scenario. This occurs when a power management (PM)
interrupt triggers just before the device-specific driver (e.g.,
qat_4xxx.ko) is unloaded, while the core driver (intel_qat.ko) remains
loaded.

Since the driver uses a shared workqueue (`qat_misc_wq`) across all
devices and owned by intel_qat.ko, a deferred routine from the
device-specific driver may still be pending in the queue. If this
routine executes after the driver is unloaded, it can dereference freed
memory, resulting in a page fault and kernel crash like the following:

    BUG: unable to handle page fault for address: ffa000002e50a01c
    #PF: supervisor read access in kernel mode
    RIP: 0010:pm_bh_handler+0x1d2/0x250 [intel_qat]

      worker_thread+0x277/0x3a0
      kthread+0xf0/0x120
      ret_from_fork+0x2d/0x50

To prevent this, flush the misc workqueue during device shutdown to
ensure that all pending work items are completed before the driver is
unloaded.

Note: This approach may slightly increase shutdown latency if the
workqueue contains jobs from other devices, but it ensures correctness
and stability.

f0ae287c50 crypto: hisilicon/sec2 - implement full backlog mode for sec
This patch introduces a hierarchical backlog mechanism to cache
user data in high-throughput encryption/decryption scenarios,
the implementation addresses packet loss issues when hardware
queues overflow during peak loads.

First, we use sec_alloc_req_id to obtain an exclusive resource
from the pre-allocated resource pool of each queue, if no resource
is allocated, perform the DMA map operation on the request memory.

When the task is ready, we will attempt to send it to the hardware,
if the hardware queue is already full, we cache the request into
the backlog list, then return an EBUSY status to the upper layer
and instruct the packet-sending thread to pause transmission.
Simultaneously, when the hardware completes a task, it triggers
the sec callback function, within this function, reattempt to send
the requests from the backlog list and wake up the sending thread
until the hardware queue becomes fully occupied again.

In addition, it handles such exceptions like the hardware is reset
when packets are sent, it will switch to the software computing
and release occupied resources.

skcipher_walk_done() can call kfree(), which takes a spinlock, which

Therefore, end the kernel-mode FPU section before calling
skcipher_walk_done(), and restart it afterwards.

Moreover, pass atomic=false to skcipher_walk_aead_encrypt() instead of
atomic=true.  The point of atomic=true was to make skcipher_walk_done()
safe to call while in a kernel-mode FPU section, but that does not
actually work.  So just use the usual atomic=false.

75e2d4b1ed crypto: caam - avoid option aliasing with the CONFIG_CAAM_QI build option
In the Makefile, the new build option CONFIG_CAAM_QI is defined conditioned
on the existence of the CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI, which is
properly defined in the Kconfig file. So, CONFIG_CAAM_QI is just a local
alias for CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI.

There is little benefit in the source code of having this slightly shorter
alias for this configuration, but it complicates further maintenance, as
searching for the impact of CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI
requires to grep once, and then identify the option introduced and continue
searching for that. Further, tools, such as cross referencers, and scripts
to check Kconfig definitions and their use simply do not handle this
situation. Given that this is the only incidence of such a config alias in
the whole kernel tree, just prefer to avoid this pattern of aliasing here.

Use CONFIG_CRYPTO_DEV_FSL_CAAM_CRYPTO_API_QI throughout the Freescale
CAAM-Multicore platform driver backend source code.
