Due to the scan command may only request legacy bands and PSC channel in 6GHz band, we are unable to scan the APs on non-PSC channel in this case. Enable WIPHY_FLAG_SPLIT_SCAN_6GHZ to support non-PSC channel (obtained during scan on legacy bands) in 6GHz scan request. Fixes: 50ac15a5 ("mt76: mt7921: add 6GHz support") Signed-off-by:

The stats are clear-on-read, which makes it very difficult for tools to adequately deal with wrapped stats and with keeping good totals. So, accumulate these values when they are read from the firmware/radio and present totals to user-space. Signed-off-by:

txs may be dropped if the frame is aggregated in AMSDU. When the problem shows up, some SKBs would be hold in driver to cause network stopped temporarily. Even if the problem can be recovered by txs timeout handling, mt7921 still need to disable txs in AMSDU to avoid this issue.

Add support for the MediaTek MT7981 SoC which is similar to the MT7986 but with a newer IP cores and only 2x ARM Cortex-A53 instead of 4x. Unlike MT7986 the MT7981 can only connect a single wireless frontend, usually MT7976 is used for DBDC. Signed-off-by:

Concurrent binding/non-binding skbs could be handled anywhere which leads to mixed byte counting, so switch to use PPDU TxS reporting regardless Tx paths when WED is active. Fixes: 43eaa368 ("wifi: mt76: add PPDU based TxS support for WED device") Co-developed-by:

PPDU TxS can only report MPDU count whereas mac80211 requires MSDU scale (NL80211_STA_INFO_TX_PACKETS), so switch to get MSDU counts from WA statistic. Note that mt7915 WA firmware only counts tx_packet for WED path, so driver needs to take care of host path additionally.

The Group ID Management frame is an Action frame of category VHT. It is transmitted by the AP to assign or change the user position of a STA for one or more group IDs. Also, sniffer can use a given group id to monitor STA that belongs to that group. Notify underlying driver of changes via BSS_CHANGED_MU_GROUPS. Signed-off-by:

When header translation failure is indicated, the hardware will insert an extra 2-byte field containing the data length after the protocol type field. This happens either when the LLC-SNAP pattern did not match, or if a VLAN header was detected. The previous commit accidentally breaks the logic, so reverts back.

mt7921_usb_sdio_tx_prepare_skb() calls mt7921_usb_sdio_write_txwi() and mt7921_skb_add_usb_sdio_hdr(), both of which blindly assume that adequate headroom will be available in the passed skb. This assumption typically is satisfied when the skb was allocated in the net core for transmission via the mt7921 netdev (although even that is only an optimization and is not strictly guaranteed), but the assumption is sometimes not satisfied when the skb originated in the receive path of another netdev and was passed through to the mt7921, such as by the bridge layer. Blindly prepending bytes to an skb is always wrong. This commit introduces a call to skb_cow_head() before the call to mt7921_usb_sdio_write_txwi() in mt7921_usb_sdio_tx_prepare_skb() to ensure that at least MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE bytes can be pushed onto the skb. Without this fix, I can trivially cause kernel panics by bridging an MT7921AU-based USB 802.11ax interface with an Ethernet interface on an Intel Atom-based x86 system using its onboard RTL8169 PCI Ethernet adapter and also on an ARM-based Raspberry Pi 1 using its onboard SMSC9512 USB Ethernet adapter. Note that the panics do not occur in every system configuration, as they occur only if the receiving netdev leaves less headroom in its received skbs than the mt7921 needs for its SDIO headers. Here is an example stack trace of this panic on Raspberry Pi OS Lite 2023-02-21 running kernel 6.1.24+ [1]: skb_panic from skb_push+0x44/0x48 skb_push from mt7921_usb_sdio_tx_prepare_skb+0xd4/0x190 [mt7921_common] mt7921_usb_sdio_tx_prepare_skb [mt7921_common] from mt76u_tx_queue_skb+0x94/0x1d0 [mt76_usb] mt76u_tx_queue_skb [mt76_usb] from __mt76_tx_queue_skb+0x4c/0xc8 [mt76] __mt76_tx_queue_skb [mt76] from mt76_txq_schedule.part.0+0x13c/0x398 [mt76] mt76_txq_schedule.part.0 [mt76] from mt76_txq_schedule_all+0x24/0x30 [mt76] mt76_txq_schedule_all [mt76] from mt7921_tx_worker+0x58/0xf4 [mt7921_common] mt7921_tx_worker [mt7921_common] from __mt76_worker_fn+0x9c/0xec [mt76] __mt76_worker_fn [mt76] from kthread+0xbc/0xe0 kthread from ret_from_fork+0x14/0x34 After this fix, bridging the mt7921 interface works fine on both of my previously problematic systems.

Allow moving the wiphy device for mwififex to a non-inital network namespace. Many wireless drivers enable this flag implicitly by initializing through the generic ieee80211_alloc_hw_nm function. As mwifiex does not utilize this function WIPHY_FLAG_NETNS_OK must be set explicitly. Moving to network namespace and working connection tested using wpa_supplicant from a network namespace as well as from a container on GyroidOS. The hardware was the Toradex Apalis i.MX8QM Board using the Azurewave AW-CM276NF wireless module. Signed-off-by:

When compiling with gcc 13.1 and CONFIG_FORTIFY_SOURCE=y, I've noticed the following: In function ‘fortify_memcpy_chk’, inlined from ‘mwifiex_construct_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:765:3, inlined from ‘mwifiex_send_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:856:6: ./include/linux/fortify-string.h:529:25: warning: call to ‘__read_overflow2_field’ declared with attribute warning: detected read beyond size of field (2nd parameter); maybe use struct_group()? [-Wattribute-warning] 529 | __read_overflow2_field(q_size_field, size); | ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The compiler actually complains on: memmove(pos + ETH_ALEN, &mgmt->u.action.category, sizeof(mgmt->u.action.u.tdls_discover_resp)); and it happens because the fortification logic interprets this as an attempt to overread 1-byte 'u.action.category' member of 'struct ieee80211_mgmt'. To silence this warning, it's enough to pass an address of 'u.action' itself instead of an address of its first member. This also fixes an improper usage of 'sizeof()'. Since 'skb' is extended with 'sizeof(mgmt->u.action.u.tdls_discover_resp) + 1' bytes (where 1 is actually 'sizeof(mgmt->u.action.category)'), I assume that the same number of bytes should be copied.

If there is a failure during kstrtobool_from_user() rtw89_debug_priv_btc_manual_set should return a negative error code instead of returning the count directly. Fix this bug by returning an error code instead of a count after a failed call of the function "kstrtobool_from_user". Moreover I omitted the label "out" with this source code correction.
