6dcadb2ed3 wifi: iwlwifi: mvm: avoid NULL pointer dereference
[ Upstream commit 557a6cd847 ]

iwl_mvm_tx_skb_sta() and iwl_mvm_tx_mpdu() verify that the mvmvsta
pointer is not NULL.
It retrieves this pointer using iwl_mvm_sta_from_mac80211, which is
dereferencing the ieee80211_sta pointer.
If sta is NULL, iwl_mvm_sta_from_mac80211 will dereference a NULL
pointer.
Fix this by checking the sta pointer before retrieving the mvmsta
from it. If sta is not NULL, then mvmsta isn't either.

3241162554 wifi: iwlwifi: mvm: use correct key iteration
[ Upstream commit 4f1591d292 ]

In the cases changed here, key iteration isn't done from
an RCU critical section, but rather using the wiphy lock
as protection. Therefore, just use ieee80211_iter_keys().
The link switch case can therefore also use sync commands.

239ac7faea wifi: rtw89: correct base HT rate mask for firmware
[ Upstream commit 45742881f9 ]

Coverity reported that u8 rx_mask << 24 will become signed 32 bits, which
casting to unsigned 64 bits will do sign extension. For example,
putting 0x80000000 (signed 32 bits) to a u64 variable will become
0xFFFFFFFF_80000000.

The real case we meet is:
  rx_mask[0...3] = ff ff 00 00
  ra_mask = 0xffffffff_ff0ff000

After this fix:
  rx_mask[0...3] = ff ff 00 00
  ra_mask = 0x00000000_ff0ff000

Fortunately driver does bitwise-AND with incorrect ra_mask and supported
rates (1ss and 2ss rate only) afterward, so the final rate mask of
original code is still correct.

7a552bc2f3 wifi: ath11k: fix array out-of-bound access in SoC stats
[ Upstream commit 69f253e46a ]

Currently, the ath11k_soc_dp_stats::hal_reo_error array is defined with a
maximum size of DP_REO_DST_RING_MAX. However, the ath11k_dp_process_rx()
function access ath11k_soc_dp_stats::hal_reo_error using the REO
destination SRNG ring ID, which is incorrect. SRNG ring ID differ from
normal ring ID, and this usage leads to out-of-bounds array access. To fix
this issue, modify ath11k_dp_process_rx() to use the normal ring ID
directly instead of the SRNG ring ID to avoid out-of-bounds array access.

d76360adab wifi: iwlwifi: mvm: drop wrong STA selection in TX
[ Upstream commit 1c7e1068a7 ]

This shouldn't happen at all, since in station mode all MMPDUs
go through the TXQ for the STA, and not this function. There
may or may not be a race in mac80211 through which this might
happen for some frames while a station is being added, but in
that case we can also just drop the frame and pretend the STA
didn't exist yet.

Also, the code is simply wrong since it uses deflink, and it's
not easy to fix it since the mvmvif->ap_sta pointer cannot be
used without the mutex, and perhaps the right link might not
even be known.

Just drop the frame at that point instead of trying to fix it
up.

191e8d5256 wifi: iwlwifi: mvm: Fix a race in scan abort flow
[ Upstream commit 87c1c28a9a ]

When the upper layer requests to cancel an ongoing scan, a race
is possible in which by the time the driver starts to handle the
upper layers scan cancel flow, the FW already completed handling
the scan request and the driver received the scan complete
notification but still did not handle the notification. In such a
case the FW will simply ignore the scan abort request coming from
the driver, no notification would arrive from the FW and the entire
abort flow would be considered a failure.

To better handle this, check the status code returned by the FW for
the scan abort command. In case the status indicates that
no scan was aborted, complete the scan abort flow with success, i.e.,
the scan was aborted, as the flow is expected to consume the scan
complete notification.

e37e348835 wifi: ath9k_htc: Use __skb_set_length() for resetting urb before resubmit
[ Upstream commit 94745807f3 ]

Syzbot points out that skb_trim() has a sanity check on the existing length of
the skb, which can be uninitialised in some error paths. The intent here is
clearly just to reset the length to zero before resubmitting, so switch to
calling __skb_set_length(skb, 0) directly. In addition, __skb_set_length()
already contains a call to skb_reset_tail_pointer(), so remove the redundant
call.

The syzbot report came from ath9k_hif_usb_reg_in_cb(), but there's a similar
usage of skb_trim() in ath9k_hif_usb_rx_cb(), change both while we're at it.

fdc73f2cfb wifi: rtw89: avoid to add interface to list twice when SER
[ Upstream commit 7dd5d2514a ]

If SER L2 occurs during the WoWLAN resume flow, the add interface flow
is triggered by ieee80211_reconfig(). However, due to
rtw89_wow_resume() return failure, it will cause the add interface flow
to be executed again, resulting in a double add list and causing a kernel
panic. Therefore, we have added a check to prevent double adding of the
list.

rx bitrate:     86.7 MBit/s VHT-MCS 9 VHT-NSS 1

This is because the RX band width is calculated incorrectly. Fix the
calculation according to the phydm_rxsc_2_bw() function from the
official drivers.

After:

tx bitrate:     866.7 MBit/s VHT-MCS 9 80MHz short GI VHT-NSS 2
rx bitrate:     390.0 MBit/s VHT-MCS 9 80MHz VHT-NSS 1

commit 0af8cd2822 upstream.

Remove VID/PID 0bda:c82c as it was inadvertently added to the device
list in driver rtw8821cu. This VID/PID is for the rtw8822cu device
and it is already in the appropriate place for that device.

d71300d07f wifi: rtw88: Fix USB/SDIO devices not transmitting beacons
commit faa2e484b3 upstream.

All USB devices supported by rtw88 have the same problem: they don't
transmit beacons in AP mode. (Some?) SDIO devices are also affected.
The cause appears to be clearing BIT_EN_BCNQ_DL of REG_FWHW_TXQ_CTRL
before uploading the beacon reserved page, so don't clear the bit for
USB and SDIO devices.

Tested with RTL8811CU and RTL8723DU.

84398204c5 wifi: wilc1000: fix potential RCU dereference issue in wilc_parse_join_bss_param
[ Upstream commit 6d7c6ae1ef ]

In the `wilc_parse_join_bss_param` function, the TSF field of the `ies`
structure is accessed after the RCU read-side critical section is
unlocked. According to RCU usage rules, this is illegal. Reusing this
pointer can lead to unpredictable behavior, including accessing memory
that has been updated or causing use-after-free issues.

This possible bug was identified using a static analysis tool developed
by myself, specifically designed to detect RCU-related issues.

To address this, the TSF value is now stored in a local variable
`ies_tsf` before the RCU lock is released. The `param->tsf_lo` field is
then assigned using this local variable, ensuring that the TSF value is
safely accessed.

aafd6ad1d9 wifi: ath12k: match WMI BSS chan info structure with firmware definition
[ Upstream commit dd98d54db2 ]

struct wmi_pdev_bss_chan_info_event is not similar to the firmware
struct definition, this will cause some random failures.

Fix by matching the struct wmi_pdev_bss_chan_info_event with the
firmware structure definition.

d45fe0115e wifi: ath12k: fix BSS chan info request WMI command
[ Upstream commit 59529c982f ]

Currently, the firmware returns incorrect pdev_id information in
WMI_PDEV_BSS_CHAN_INFO_EVENTID, leading to incorrect filling of
the pdev's survey information.

To prevent this issue, when requesting BSS channel information
through WMI_PDEV_BSS_CHAN_INFO_REQUEST_CMDID, firmware expects
pdev_id as one of the arguments in this WMI command.

Add pdev_id to the struct wmi_pdev_bss_chan_info_req_cmd and fill it
during ath12k_wmi_pdev_bss_chan_info_request(). This resolves the
issue of sending the correct pdev_id in WMI_PDEV_BSS_CHAN_INFO_EVENTID.

dda028a8aa wifi: ath9k: Remove error checks when creating debugfs entries
[ Upstream commit f6ffe7f018 ]

We should not be checking the return values from debugfs creation at all: the
debugfs functions are designed to handle errors of previously called functions
and just transparently abort the creation of debugfs entries when debugfs is
disabled. If we check the return value and abort driver initialisation, we break
the driver if debugfs is disabled (such as when booting with debugfs=off).

Earlier versions of ath9k accidentally did the right thing by checking the
return value, but only for NULL, not for IS_ERR(). This was "fixed" by the two
commits referenced below, breaking ath9k with debugfs=off starting from the 6.6
kernel (as reported in the Bugzilla linked below).

Restore functionality by just getting rid of the return value check entirely.

fb1862ce26 wifi: brcmfmac: introducing fwil query functions
[ Upstream commit c6002b6c05 ]

When the firmware interface layer was refactored it provided various
"get" and "set" functions. For the "get" in some cases a parameter
needed to be passed down to firmware as a key indicating what to
"get" turning the output parameter of the "get" function into an
input parameter as well. To accommodate this the "get" function blindly
copies the parameter which in some places resulted in an uninitialized
warnings from the compiler. These have been fixed by initializing the
input parameter in the past. Recently another batch of similar fixes
were submitted to address clang static checker warnings [1].

Proposing another solution by introducing a "query" variant which is used
when the (input) parameter is needed by firmware. The "get" variant will
only fill the (output) parameter with the result received from firmware
taking care of proper endianess conversion.

In 'rtw_wait_firmware_completion()', always wait for both (regular and
wowlan) firmware loading attempts. Otherwise if 'rtw_usb_intf_init()'
has failed in 'rtw_usb_probe()', 'rtw_usb_disconnect()' may issue
'ieee80211_free_hw()' when one of 'rtw_load_firmware_cb()' (usually
the wowlan one) is still in progress, causing UAF detected by KASAN.

021cd8f0e4 wifi: iwlwifi: clear trans->state earlier upon error
[ Upstream commit 094513f8a2 ]

When the firmware crashes, we first told the op_mode and only then,
changed the transport's state. This is a problem if the op_mode's
nic_error() handler needs to send a host command: it'll see that the
transport's state still reflects that the firmware is alive.

Today, this has no consequences since we set the STATUS_FW_ERROR bit and
that will prevent sending host commands. iwl_fw_dbg_stop_restart_recording
looks at this bit to know not to send a host command for example.

To fix the hibernation, we needed to reset the firmware without having
an error and checking STATUS_FW_ERROR to see whether the firmware is
alive will no longer hold, so this change is necessary as well.

Change the flow a bit.
Change trans->state before calling the op_mode's nic_error() method and
check trans->state instead of STATUS_FW_ERROR. This will keep the
current behavior of iwl_fw_dbg_stop_restart_recording upon firmware
error, and it'll allow us to call iwl_fw_dbg_stop_restart_recording
safely even if STATUS_FW_ERROR is clear, but yet, the firmware is not
alive.

4d0a900ec4 wifi: iwlwifi: mvm: don't wait for tx queues if firmware is dead
[ Upstream commit 3a84454f52 ]

There is a WARNING in iwl_trans_wait_tx_queues_empty() (that was
recently converted from just a message), that can be hit if we
wait for TX queues to become empty after firmware died. Clearly,
we can't expect anything from the firmware after it's declared dead.

Don't call iwl_trans_wait_tx_queues_empty() in this case. While it could
be a good idea to stop the flow earlier, the flush functions do some
maintenance work that is not related to the firmware, so keep that part
of the code running even when the firmware is not running.
