2023-09-30wifi: mt76: mt7603: improve stuck beacon handlingFelix Fietkau
Before preparing the new beacon, check the queue status, flush out all previous beacons and buffered multicast packets, then (if necessary) try to recover more gracefully from a stuck beacon condition by making a less invasive attempt at getting the MAC un-stuck.

2023-09-30wifi: mt76: mt7603: improve watchdog reset reliablityFelix Fietkau
Only trigger PSE reset if PSE was stuck, otherwise it can cause DMA issues. Trigger the PSE reset while DMA is fully stopped in order to improve reliabilty. Fixes: c8846e101502 ("mt76: add driver for MT7603E and MT7628/7688") Signed-off-by: Felix Fietkau <nbd@nbd.name>
2023-09-30wifi: mt76: mt7603: rework/fix rx pse hang checkFelix Fietkau
It turns out that the code in mt7603_rx_pse_busy() does not detect actual hardware hangs, it only checks for busy conditions in PSE. A reset should only be performed if these conditions are true and if there is no rx activity as well. Reset the counter whenever a rx interrupt occurs. In order to also deal with a fully loaded CPU that leaves interrupts disabled with continuous NAPI polling, also check for pending rx interrupts in the function itself.

2023-09-22wifi: mt76: mt76x02: fix MT76x0 external LNA gain handlingFelix Fietkau
On MT76x0, LNA gain should be applied for both external and internal LNA. On MT76x2, LNA gain should be treated as 0 for external LNA. Move the LNA type based logic to mt76x2 in order to fix mt76x0.

2023-09-19net: ethernet: mtk_wed: rename mtk_rxbm_desc in mtk_wed_bm_descLorenzo Bianconi
Rename mtk_rxbm_desc structure in mtk_wed_bm_desc since it will be used even on tx side by MT7988 SoC. Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Paolo Abeni <pabeni@redhat.com>
2023-09-11wifi: cfg80211: annotate iftype_data pointer with sparseJohannes Berg
There were are a number of cases in mac80211 and iwlwifi (at least) that used the sband->iftype_data pointer directly, instead of using the accessors to find the right array entry to use. Make sparse warn when such a thing is done. To not have a lot of casts, add two helper functions/macros - ieee80211_set_sband_iftype_data() - for_each_sband_iftype_data() Signed-off-by: Johannes Berg <johannes.berg@intel.com>

2023-08-25Fix nomenclature for USB and PCI wireless devicesAlan Stern
A mouse that uses a USB connection is called a "USB mouse" device (or "USB mouse" for short), not a "mouse USB" device. By analogy, a WiFi adapter that connects to the host computer via USB is a "USB wireless" device, not a "wireless USB" device. (The latter term more properly refers to a defunct Wireless USB specification, which described a technology for sending USB protocol messages over an ultra wideband radio link.) Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a "PCIe wireless" device, not a "wireless PCIe" device. Rephrase the text in the kernel source where the word ordering is wrong.

2023-08-09USB: Remove remnants of Wireless USB and UWBAlan Stern
Wireless USB has long been defunct, and kernel support for it was removed in 2020 by commit caa6772db4c1 ("Staging: remove wusbcore and UWB from the kernel tree."). Nevertheless, some vestiges of the old implementation still clutter up the USB subsystem and one or two other places. Let's get rid of them once and for all. The only parts still left are the user-facing APIs in include/uapi/linux/usb/ch9.h. (There are also a couple of misleading instances, such as the Sierra Wireless USB modem, which is a USB modem made by Sierra Wireless.)

2023-08-02wifi: mt76: Replace strlcpy() with strscpy()Azeem Shaikh
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). Direct replacement is safe here since DEV_ASSIGN is only used by TRACE macros and the return values are ignored.

2023-08-01wifi: drivers: Explicitly include correct DT includesRob Herring
The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

2023-07-26wifi: mt76: mt7603: fix tx filter/flush functionFelix Fietkau
Setting MT_TX_ABORT does not abort any transmission for a wtbl index on its own. Instead, it modifies the behavior of a queue flush to make it selectively flush packets for a particular wtbl index. Adjust powersave filtering to make use of this in order to avoid running into unnecessary timeouts while flushing Signed-off-by: Felix Fietkau <nbd@nbd.name>
2023-07-26wifi: mt76: mt7603: fix beacon interval after disabling a single vifFelix Fietkau
When disabling beacons on a vif, intval is 0. Ensure that dev->mt76.beacon_int is not overwritten in this case, so that beacons continue to work for other interfaces. Signed-off-by: Felix Fietkau <nbd@nbd.name>

The IEEE80211_VHT_CAP_EXT_NSS_BW value already indicates support for half-NSS 160 MHz support, so it is wrong to also advertise full 160 MHz support. Fixes: c2f73eacee3b ("wifi: mt76: mt7915: add back 160MHz channel width support for MT7915") Signed-off-by: Felix Fietkau <nbd@nbd.name>
