2021-10-23mt76: Print error message when reading EEPROM from mtd failedHauke Mehrtens
When the EEPROM data is stored on a MTD partition print an error message when reading this MTD partition failed. This is currently happening often in OpenWrt because the initial data was written with using a flash driver which ignores the error detection data and now OpenWrt uses a driver which checks it. With this patch a better error message is shown: [ 8.986988] mt7915e 0000:01:00.0: WA Firmware Version: DEV_000000, Build Time: 20201105222323 [ 9.100508] mt7915e 0000:01:00.0: reading EEPROM from mtd factory failed: -117 [ 9.144289] mt7915e: probe of 0000:01:00.0 failed with error -22 mt7915 does not work without an EEPROM, MT7922 still works.

2021-10-23mt76: mt7615: mt7622: fix ibss and meshpointNick Hainke
commit 7f4b7920318b ("mt76: mt7615: add ibss support") introduced IBSS and commit f4ec7fdf7f83 ("mt76: mt7615: enable support for mesh") meshpoint support. Both used in the "get_omac_idx"-function: if (~mask & BIT(HW_BSSID_0)) return HW_BSSID_0; With commit d8d59f66d136 ("mt76: mt7615: support 16 interfaces") the ibss and meshpoint mode should "prefer hw bssid slot 1-3". However, with that change the ibss or meshpoint mode will not send any beacon on the mt7622 wifi anymore. Devices were still able to exchange data but only if a bssid already existed. Two mt7622 devices will never be able to communicate. This commits reverts the preferation of slot 1-3 for ibss and meshpoint. Only NL80211_IFTYPE_STATION will still prefer slot 1-3. Tested on Banana Pi R64.

2021-10-20mwifiex: Deactive host sleep using HSCFG after it was activated manuallyJonas Dreßler
When powersaving (so either wifi powersaving or deep sleep, depending on which state the firmware is in) is disabled, the way the firmware goes into host sleep is different: Usually the firmware implicitely enters host sleep on the next SLEEP event we get when we configured host sleep via HSCFG before. When powersaving is disabled though, there are no SLEEP events, the way we enter host sleep in that case is different: The firmware will send us a HS_ACT_REQ event and after that we "manually" make the firmware enter host sleep by sending it another HSCFG command with the action HS_ACTIVATE. Now waking up from host sleep appears to be different depending on whether powersaving is enabled again: When powersaving is enabled, the firmware implicitely leaves host sleep as soon as it wakes up and sends us an AWAKE event. When powersaving is disabled though, it apparently doesn't implicitely leave host sleep, but instead we need to send it a HSCFG command with the HS_CONFIGURE action and the HS_CFG_CANCEL condition. We didn't do that so far, which is why waking up from host sleep was broken when powersaving is disabled. So add some additional state to mwifiex_adapter where we keep track of whether host sleep was activated manually via HS_ACTIVATE, and if that was the case, deactivate it manually again via HS_CFG_CANCEL.

2021-10-20mwifiex: Send DELBA requests according to specJonas Dreßler
While looking at on-air packets using Wireshark, I noticed we're never setting the initiator bit when sending DELBA requests to the AP: While we set the bit on our del_ba_param_set bitmask, we forget to actually copy that bitmask over to the command struct, which means we never actually set the initiator bit. Fix that and copy the bitmask over to the host_cmd_ds_11n_delba command struct.

2021-10-20mwifiex: Log an error on command failure during key-material uploadJonas Dreßler
Sometimes the KEY_MATERIAL command can fail with the 88W8897 firmware (when this happens exactly seems pretty random).

2021-10-20mwl8k: Fix use-after-free in mwl8k_fw_state_machine()Zheyu Ma
When the driver fails to request the firmware, it calls its error handler. In the error handler, the driver detaches device from driver first before releasing the firmware, which can cause a use-after-free bug. Fix this by releasing firmware first. The following log reveals it: [ 9.007301 ] BUG: KASAN: use-after-free in mwl8k_fw_state_machine+0x320/0xba0 [ 9.010143 ] Workqueue: events request_firmware_work_func [ 9.010830 ] Call Trace: [ 9.010830 ] dump_stack_lvl+0xa8/0xd1 [ 9.010830 ] print_address_description+0x87/0x3b0 [ 9.010830 ] kasan_report+0x172/0x1c0 [ 9.010830 ] ? mutex_unlock+0xd/0x10 [ 9.010830 ] ? mwl8k_fw_state_machine+0x320/0xba0 [ 9.010830 ] ? mwl8k_fw_state_machine+0x320/0xba0 [ 9.010830 ] __asan_report_load8_noabort+0x14/0x20 [ 9.010830 ] mwl8k_fw_state_machine+0x320/0xba0 [ 9.010830 ] ? mwl8k_load_firmware+0x5f0/0x5f0 [ 9.010830 ] request_firmware_work_func+0x172/0x250 [ 9.010830 ] ? read_lock_is_recursive+0x20/0x20 [ 9.010830 ] ? process_one_work+0x7a1/0x1100 [ 9.010830 ] ? request_firmware_nowait+0x460/0x460 [ 9.010830 ] ? __this_cpu_preempt_check+0x13/0x20 [ 9.010830 ] process_one_work+0x9bb/0x1100 Signed-off-by: Zheyu Ma <zheyuma97@gmail.com> Signed-off-by: Kalle Valo <kvalo@codeaurora.org> Link: https://lore.kernel.org/r/1634356979-6211-1-git-send-email-zheyuma97@gmail.com

Update max rx len of some hw modules, which aligns out vendor SDK. In normal modes, we exchange MPDU 7991 cap with peers; however, this won't play a part in sniffer mode. To prevent packets which exceed the max MPDU size from entering specific rx path in hw, we need to set a proper limit to filter them out.
