df62e22c2e wifi: brcm80211: handle pmk_op allocation failure
[ Upstream commit b4152222e0 ]

The kzalloc() in brcmf_pmksa_v3_op() will return null if the
physical memory has run out. As a result, if we dereference
the null value, the null pointer dereference bug will happen.

Return -ENOMEM from brcmf_pmksa_v3_op() if kzalloc() fails
for pmk_op.

This is caused by a mistake in the chip initialisation. This version of
the chip requires loading an extra AGC table right after the main one,
but the extra table is being loaded at the wrong time, in
rtw_chip_board_info_setup().

Move the extra AGC table loading to the right place, in
rtw_phy_load_tables().

The rtw_chip_board_info_setup() can only do "software" things, and
rtw_phy_load_tables() can really do IO.

[ Upstream commit 41a7acb7dd ]

RTL8822CU, RTL8822BU, and RTL8821CU need an extra register write after

0f7bdcbb0f wifi: wilc1000: revert reset line logic flip
[ Upstream commit f3ec643947 ]

This reverts commit fcf690b0b4.

When using a wilc1000 chip over a spi bus, users can optionally define a
reset gpio and a chip enable gpio. The reset line of wilc1000 is active
low, so to hold the chip in reset, a low (physical) value must be applied.

The corresponding device tree binding documentation was introduced by
commit f31ee3c0a5 ("wilc1000: Document enable-gpios and reset-gpios
properties") and correctly indicates that the reset line is an active-low
signal. The corresponding driver part, brought by commit ec031ac479
("wilc1000: Add reset/enable GPIO support to SPI driver") was applying the
correct logic. But commit fcf690b0b4 ("wifi: wilc1000: use correct
sequence of RESET for chip Power-UP/Down") eventually flipped this logic
and started misusing the gpiod APIs, applying an inverted logic when
powering up/down the chip (for example, setting the reset line to a logic
"1" during power up, which in fact asserts the reset line when device tree
describes the reset line as GPIO_ACTIVE_LOW). As a consequence, any
platform currently using the driver in SPI mode must use a faulty reset
line description in device tree, or else chip will be maintained in reset
and will not even allow to bring up the chip.

Fix reset line usage by inverting back the gpiod APIs usage, setting the
reset line to the logic value "0" when powering the chip, and the logic
value "1" when powering off the chip.

David Mosberger-Tan initial investigation [1] showed that this
use-after-free is due to netdevice unregistration during vif list
traversal. When unregistering a net device, since the needs_free_netdev has
been set to true during registration, the netdevice object is also freed,
and as a consequence, the corresponding vif object too, since it is
attached to it as private netdevice data. The next occurrence of the loop
then tries to access freed vif pointer to the list to move forward in the
list.

Fix this use-after-free thanks to two mechanisms:
- navigate in the list with list_for_each_entry_safe, which allows to
  safely modify the list as we go through each element. For each element,
  remove it from the list with list_del_rcu
- make sure to wait for RCU grace period end after each vif removal to make
  sure it is safe to free the corresponding vif too (through
  unregister_netdev)

Since we are in a RCU "modifier" path (not a "reader" path), and because
such path is expected not to be concurrent to any other modifier (we are
using the vif_mutex lock), we do not need to use RCU list API, that's why
we can benefit from list_for_each_entry_safe.

85074e3394 wifi: iwlwifi: mvm: don't set replay counters to 0xff
[ Upstream commit d5bd4041cd ]

The firmware (later) actually uses the values even for keys
that are invalid as far as the host is concerned, later in
rekeying, and then only sets the low 48 bits since the PNs
are only 48 bits over the air. It does, however, compare the
full 64 bits later, obviously causing problems.

Remove the memset and use kzalloc instead to avoid any old
heap data leaking to the firmware. We already init all the
other fields in the struct anyway. This leaves the data set
to zero for any unused fields, so the firmware can look at
them safely even if they're not used right now.

67e7b24a70 wifi: iwlwifi: mvm: fix erroneous queue index mask
[ Upstream commit 2e0e766bd8 ]

When retrieving the queue index ("SCD SSN") from the TX response,
it's currently masked with 0xFFF. However, now that we have queues
longer than 4k, that became wrong, so make the mask depend on the
hardware family.

This fixes an issue where if we get a single frame reclaim while
in the top half of an 8k long queue, we'd reclaim-wrap the queue
twice (once on this and then again on the next non-single reclaim)
which at least triggers the WARN_ON_ONCE() in iwl_txq_reclaim(),
but could have other negative side effects (such as unmapping a
frame that wasn't transmitted yet, and then taking an IOMMU fault)
as well.

During calculate vdev_stats_id, will compare vdev_stats_id with
ATH12K_INVAL_VDEV_STATS_ID by '<='. If vdev_stats_id is relatively
small, then assign ATH12K_INVAL_VDEV_STATS_ID to vdev_stats_id.

This logic is incorrect. Firstly, should use '>=' instead of '<=' to
check if this u8 variable exceeds the max valid range.

Secondly, should use the maximum value as comparison value.

Correct comparison symbols and use the maximum value
ATH12K_MAX_VDEV_STATS_ID for comparison.

4615164c4d wifi: ath11k: initialize rx_mcs_80 and rx_mcs_160 before use
[ Upstream commit b802e7b7e7 ]

Currently in ath11k_peer_assoc_h_he() rx_mcs_80 and rx_mcs_160
are used to calculate max_nss, see
	if (support_160)
		max_nss = min(rx_mcs_80, rx_mcs_160);
	else
		max_nss = rx_mcs_80;

Kernel test robot complains on uninitialized symbols:
drivers/net/wireless/ath/ath11k/mac.c:2321 ath11k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_80'.
drivers/net/wireless/ath/ath11k/mac.c:2321 ath11k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_160'.
drivers/net/wireless/ath/ath11k/mac.c:2323 ath11k_peer_assoc_h_he() error: uninitialized symbol 'rx_mcs_80'.

This is because there are some code paths that never set them, so
the assignment of max_nss can come from uninitialized variables.
This could result in some unknown issues since a wrong peer_nss
might be passed to firmware.

Change to initialize them to an invalid value at the beginning. This
makes sense because even max_nss gets an invalid value, due to either
or both of them being invalid, we can get an valid peer_nss with
following guard:
	arg->peer_nss = min(sta->deflink.rx_nss, max_nss)

3f6548bae3 wifi: ath12k: fix fetching MCBC flag for QCN9274
[ Upstream commit 902700d55d ]

In QCN9274, RX packet's multicast and broadcast(MCBC) flag is fetched
from RX descriptor's msdu_end info5 member but it is not correct
for QCN9274. Due to this with encryption, ARP request packet is wrongly
marked as MCBC packet and it is sent to mac80211 without setting
RX_FLAG_PN_VALIDATED & RX_FLAG_DECRYPTED flag. This results in packet
getting dropped in mac80211. Hence ping initiated from station to AP
fails.

Fix this by fetching correct MCBC flag in case of QCN9274.
For QC9274 MCBC flag should be fetched from RX descriptor's mpdu_start
info6 member.

f77ba3e047 wifi: ath11k: change to move WMI_VDEV_PARAM_SET_HEMU_MODE before WMI_PEER_ASSOC_CMDID
[ Upstream commit 413e20e82e ]

Currently when connecting to an AP with 11AX-HE phy mode, host sends
WMI_VDEV_PARAM_SET_HEMU_MODE parameter to firmware after
WMI_PEER_ASSOC_CMDID command. This results in TXBF not working, because
firmware calculates TXBF values while handling WMI_PEER_ASSOC_CMDID,
however at that time WMI_VDEV_PARAM_SET_HEMU_MODE has not been sent yet.
See below log:

AP sends "VHT/HE/EHT NDP Announcement" to station, and station sends
"Action no Ack" of category code HE to AP, the "Nc Index" and
"Codebook Information" are wrong:

Issued action:
IEEE 802.11 Action No Ack, Flags: ........

                .... .... .... .... .... .... .... ..0. .... .... = Codebook Information: 0

Change to send WMI_VDEV_PARAM_SET_HEMU_MODE before WMI_PEER_ASSOC_CMDID,
then firmware will calculate the TXBF values with valid parameters
instead of empty values. TXBF works well and throughput performance is
improved from 80 Mbps to 130 Mbps with this patch.

a015fbf698 wifi: ath9k: delay all of ath9k_wmi_event_tasklet() until init is complete
[ Upstream commit 24355fcb0d ]

The ath9k_wmi_event_tasklet() used in ath9k_htc assumes that all the data
structures have been fully initialised by the time it runs. However, because of
the order in which things are initialised, this is not guaranteed to be the
case, because the device is exposed to the USB subsystem before the ath9k driver
initialisation is completed.

We already committed a partial fix for this in commit:
8b3046abc9 ("ath9k_htc: fix NULL pointer dereference at ath9k_htc_tx_get_packet()")

However, that commit only aborted the WMI_TXSTATUS_EVENTID command in the event
tasklet, pairing it with an "initialisation complete" bit in the TX struct. It
seems syzbot managed to trigger the race for one of the other commands as well,
so let's just move the existing synchronisation bit to cover the whole
tasklet (setting it at the end of ath9k_htc_probe_device() instead of inside
ath9k_tx_init()).

e479ae4c9b wifi: ath12k: Fix issues in channel list update
[ Upstream commit 67a48d937f ]

Currently, the logic used to select the 6 GHz band is incorrect,
which may cause 6 GHz supported channels to not be updated properly.
This is because the 6 GHz Max frequency supported by the driver is
being compared to the Max frequency supported on the board. If in
some cases, the 6 GHz Max frequency supported on the board is less
than the defined 6 GHz Max frequency, all 6 GHz channels are disabled.
To address this, compare the max frequency supported by the board to
the defined 6 GHz Minimum frequency by the driver.

Similarly, when a dual mac card supports both 6 GHz and 5 GHz radios,
if the 5 GHz radio gets enumerated first before 6 GHz, the checks in
ath12k_mac_setup_channels_rates() can cause the 5 GHz channels which
were enabled earlier to get disabled when the 6 GHz channel list is
updated. This is because the Min 6 GHz frequency defined in the driver
is 5945 MHz, which should be 5925 MHz since channel 2 is not considered
currently, but the firmware can pass 5925 MHz as the minimum.
Hence, update the Min frequency supported by the driver to 5925 MHz.

In addition, ensure that the channel list update to firmware updates
only the channels that the current radio (ar) supports rather than
considering the wiphy support. This would be required when multiple pdevs
are supported in a wiphy and they support different ranges of frequencies
or bands as in single wiphy support.

9ade676d25 wifi: mwifiex: debugfs: Drop unnecessary error check for debugfs_create_dir()
[ Upstream commit 50180c7f8e ]

debugfs_create_dir() returns ERR_PTR and never return NULL.

As Russell suggested, this patch removes the error checking for
debugfs_create_dir(). This is because the DebugFS kernel API is developed
in a way that the caller can safely ignore the errors that occur during
the creation of DebugFS nodes. The debugfs APIs have a IS_ERR() judge in
start_creating() which can handle it gracefully. So these checks are
unnecessary.

b66b008f1d wifi: wilc1000: fix multi-vif management when deleting a vif
[ Upstream commit 12cfc9c8d3 ]

Adding then removing a second vif currently makes the first vif not working
anymore. This is visible for example when we have a first interface
connected to some access point:
- create a wpa_supplicant.conf with some AP credentials
- wpa_supplicant -Dnl80211 -c /etc/wpa_supplicant.conf -i wlan0
- dhclient wlan0
- iw phy phy0 interface add wlan1 type managed
- iw dev wlan1 del
wlan0 does not manage properly traffic anymore (eg: ping not working)

This is due to vif mode being incorrectly reconfigured with some default
values in del_virtual_intf, affecting by default first vif.

Prevent first vif from being affected on second vif removal by removing vif
mode change command in del_virtual_intf

4041c60a9d wifi: wilc1000: do not realloc workqueue everytime an interface is added
[ Upstream commit 328efda22a ]

Commit 09ed8bfc52 ("wilc1000: Rename workqueue from "WILC_wq" to
"NETDEV-wq"") moved workqueue creation in wilc_netdev_ifc_init in order to
set the interface name in the workqueue name. However, while the driver
needs only one workqueue, the wilc_netdev_ifc_init is called each time we
add an interface over a phy, which in turns overwrite the workqueue with a
new one. This can be observed with the following commands:

for i in $(seq 0 10)
do
  iw phy phy0 interface add wlan1 type managed
  iw dev wlan1 del
done
ps -eo pid,comm|grep wlan

 39 kworker/R-wlan0
 98 kworker/R-wlan1
102 kworker/R-wlan1
105 kworker/R-wlan1
108 kworker/R-wlan1
111 kworker/R-wlan1
114 kworker/R-wlan1
117 kworker/R-wlan1
120 kworker/R-wlan1
123 kworker/R-wlan1
126 kworker/R-wlan1
129 kworker/R-wlan1

Fix this leakage by putting back hif_workqueue allocation in
wilc_cfg80211_init. Regarding the workqueue name, it is indeed relevant to
set it lowercase, however it is not  attached to a specific netdev, so
enforcing netdev name in the name is not so relevant. Still, enrich the
name with the wiphy name to make it clear which phy is using the workqueue.

7b9fe69c3b wifi: b43: Disable QoS for bcm4331
[ Upstream commit 09795bded2 ]

bcm4331 seems to not function correctly with QoS support. This may be due
to issues with currently available firmware or potentially a device
specific issue.

When queues that are not of the default "best effort" priority are
selected, traffic appears to not transmit out of the hardware while no
errors are returned. This behavior is present among all the other priority
queues: video, voice, and background. While this can be worked around by
setting a kernel parameter, the default behavior is problematic for most
users and may be difficult to debug. This patch offers a working out-of-box
experience for bcm4331 users.

We should check whether the WMI_TLV_TAG_STRUCT_MGMT_TX_COMPL_EVENT tlv is
present before accessing it, otherwise a null pointer deference error will
occur.

ae668e2e60 wifi: iwlwifi: mvm: use correct address 3 in A-MSDU
[ Upstream commit 2e57b77583 ]

As described in IEEE sta 802.11-2020, table 9-30 (Address
field contents), A-MSDU address 3 should contain the BSSID
address.

In TX_CMD we copy the MAC header from skb, and skb address 3
holds the destination address, but it may not be identical to
the BSSID.

Using the wrong destination address appears to work with (most)
receivers without MLO, but in MLO some devices are checking for
it carefully, perhaps as a consequence of link to MLD address
translation.

Replace address 3 in the TX_CMD MAC header with the correct
address while retaining the skb address 3 unchanged.
This ensures that skb address 3 will be utilized later for
constructing the A-MSDU subframes.

Note that we fill in the MLD address, but the firmware will do the
necessary translation to link address after encryption.

[ Upstream commit a23c0af103 ]

mac80211 does not have proper support for EPCS currently as that would
require changing the ECDA parameters if EPCS (Emergency Preparedness
Communications Service) is in use. As such, do not announce support for
it in the capabilities.
