ath11k: send beacon template after vdev_start/restart during csa

Firmware has added assert if beacon template is received after
vdev_down. Firmware expects beacon template after vdev_start
and before vdev_up. This change is needed to support MBSSID EMA
cases in firmware.

Hence, Change the sequence in ath11k as expected from firmware.
This new change is not causing any issues with older
firmware.

rsi: fix AP mode with WPA failure due to encrypted EAPOL

In AP mode WPA2-PSK connections were not established.

The reason was that the AP was sending the first message
of the 4 way handshake encrypted, even though no pairwise
key had (correctly) yet been set.

Encryption was enabled if the "security_enable" driver flag
was set and encryption was not explicitly disabled by
IEEE80211_TX_INTFL_DONT_ENCRYPT.

However security_enable was set when *any* key, including
the AP GTK key, had been set which was causing unwanted
encryption even if no key was avaialble for the unicast
packet to be sent.

Fix this by adding a check that we have a key and drop
the old security_enable driver flag which is insufficient
and redundant.

The Redpine downstream out of tree driver does it this way too.

Regarding the Fixes tag the actual code being modified was
introduced earlier, with the original driver submission, in
dad0d04fa7ba ("rsi: Add RS9113 wireless driver"), however
at that time AP mode was not yet supported so there was
no bug at that point.

So I have tagged the introduction of AP support instead
which was part of the patch set "rsi: support for AP mode" [1]

It is not clear whether AP WPA has ever worked, I can see nothing
on the kernel side that broke it afterwards yet the AP support
patch series says "Tests are performed to confirm aggregation,
connections in WEP and WPA/WPA2 security."

One possibility is that the initial tests were done with a modified
userspace (hostapd).

cw1200: Revert unnecessary patches that fix unreal use-after-free bugs

A previous commit 4f68ef64cd7f ("cw1200: Fix concurrency
use-after-free bugs in cw1200_hw_scan()") tried to fix a seemingly
use-after-free bug between cw1200_bss_info_changed() and
cw1200_hw_scan(), where the former frees a sk_buff pointed
to by frame.skb, and the latter accesses the sk_buff
pointed to by frame.skb. However, this issue should be a
false alarm because:

(1) "frame.skb" is not a shared variable between the above
two functions, because "frame" is a local function variable,
each of the two functions has its own local "frame" - they
just happen to have the same variable name.

(2) the sk_buff(s) pointed to by these two "frame.skb" are
also two different object instances, they are individually
allocated by different dev_alloc_skb() within the two above
functions. To free one object instance will not invalidate
the access of another different one.

Based on these facts, the previous commit should be unnecessary.
Moreover, it also introduced a missing unlock which was
addressed in a subsequent commit 51c8d24101c7 ("cw1200: fix missing
unlock on error in cw1200_hw_scan()"). Now that the
original use-after-free is unreal, these two commits should
be reverted. This patch performs the reversion.

brcmsmac: Drop unnecessary NULL check after container_of

The parameter passed to ai_detach() is guaranteed to never be NULL
because it is checked by the caller. Consequently, the result of
container_of() on it is also never NULL, and a NULL check on it
is unnecessary. Even without that, the NULL check would still be
unnecessary because the subsequent kfree() can handle NULL arguments.
On top of all that, it is misleading to check the result of container_of()
against NULL because the position of the contained element could change,
which would make the check invalid. Remove it.

wlcore: fix read pointer update

When reading the fw_log structure from the device's memory, we could
race with the firmware updating the actual_buff_size and buff_write_ptr
members of this structure. This would lead to bytes being dropped from
the log.

Fix this by writing back the actual - now fixed - clear_ptr which
reflects where we read up to in the buffer.

This also means that we must not check that the clear_ptr matches the
current write pointer, so remove that check.

wlcore/wl12xx: Fix wl12xx get_mac error if device is in ELP

At least on wl12xx, reading the MAC after boot can fail with a warning
at drivers/net/wireless/ti/wlcore/sdio.c:78 wl12xx_sdio_raw_read.
The failed call comes from wl12xx_get_mac() that wlcore_nvs_cb() calls
after request_firmware_work_func().

After the error, no wireless interface is created. Reloading the wl12xx
module makes the interface work.

Turns out the wlan controller can be in a low-power ELP state after the
boot from the bootloader or kexec, and needs to be woken up first.

Let's wake the hardware and add a sleep after that similar to
wl12xx_pre_boot() is already doing.

Note that a similar issue could exist for wl18xx, but I have not seen it
so far. And a search for wl18xx_get_mac and wl12xx_sdio_raw_read did not

wcn36xx: Enable WOWLAN flags

Enable flags for

- Magic packet
- GTK rekey

Previous patches implemented the necessary code to switch these two on.
Standalone magic packet absent GTK rekey is pretty useless, so it makes
sense to flag both at once.

Once done it is possible for wcn36xx firmware to

1. Respond to ipv4 and ipv6 ARP/NS lookup requests
2. Bring the system out of suspend when a magic packet is received.
   Magic in our case is a simple ipv4 or ipv6 unicast.
3. GTK rekey whilst in suspend
   Once we wake from suspend the GTK will be updated as necessary

wcn36xx: Add host resume request support

This commit is the corresponding resume() path request to the firmware when
resuming. Unlike the suspend() version which is a unidirectional
indication, the resume version is a standard request/response.

Once the resume() request completes ipv4 ARP, ipv6 NS and GTK rekey offload
stop working and can subsequently be rolled back.

ath9k: Fix kernel NULL pointer dereference during ath_reset_internal()

I got this crash more times during debugging of PCIe controller and crash
happens somehow at the time when PCIe kernel code started link retraining (as
part of ASPM code) when at the same time PCIe link went down and ath9k probably
executed hw reset procedure.

Currently I'm not able to reproduce this issue as it looks like to be
some race condition between link training, ASPM, link down and reset
path. And as always, race conditions which depends on more input
parameters are hard to reproduce as it depends on precise timings.

But it is clear that pointers are zero in this case and should be
properly filled as same code pattern is used in ath9k_stop() function.
Anyway I was able to reproduce this crash by manually triggering ath
reset worker prior putting card up. I created simple patch to export
reset functionality via debugfs and use it to "simulate" of triggering
reset.    s proved that NULL-pointer dereference issue is there.

Function ath9k_hw_reset() is dereferencing chan structure pointer, so it
needs to be non-NULL pointer.

Function ath9k_stop() already contains code which sets ah->curchan to valid
non-NULL pointer prior calling ath9k_hw_reset() function.

Add same code pattern also into ath_reset_internal() function to prevent
kernel NULL pointer dereference in ath9k_hw_reset() function.

This change fixes kernel NULL pointer dereference in ath9k_hw_reset() which
is caused by calling ath9k_hw_reset() from ath_reset_internal() with NULL
chan structure.

These TODO empty code are added by
commit 9442e5b58edb ("b43: N-PHY: partly implement SPUR workaround"). It's
been more than a decade now. I don't think anyone who wants to perfect
this workaround can follow this TODO tip exactly. Instead, it limits them
to new thinking. Remove it will be better.

No functional change.

By the way, this helps reduce some binary code size.

Jesse Brandeburg says:

In this series I address the C=2 (sparse) warnings. The goal is to be
completely sparse clean in the drivers/net/ethernet/intel directory.
This can help us run this tool for every patch, and helps the kernel
code by reducing technical debt.

NOTE: there is one warning left in ixgbe XDP code using rcu_assign_pointer().

  igbvf: convert to strongly typed descriptors
  intel: call csum functions with well formatted arguments
  igb: override two checker warnings
  igb: fix assignment on big endian machines
  igb: handle vlan types with checker enabled
  igb/igc: use strongly typed pointer

ixgbe: reduce checker warnings

Fix the sparse warnings in the ixgbe crypto offload code. These
changes were made in the most conservative way (force cast)
in order to hopefully not break the code. I suspect that the
code might still be broken on big-endian architectures, but
no one is complaining, so I'm just leaving it functionally
the same.
