2021-06-19mt76: mt7915: add thermal cooling device supportRyder Lee4-0/+194
Thermal cooling device support is added to control the temperature by throttling the data transmission for the given duration. Throttling is done by adjusting Tx period by given percentage of time. The thermal device allows user to configure duty cycle. Throttling can be disabled by setting the duty cycle to 0. The cooling device can be found under /sys/class/thermal/cooling_deviceX/. Corresponding soft link to this device can be found under phy folder To set duty cycle as 80%, echo 80 > /sys/class/ieee80211/phy*/cooling_device/cur_state Signed-off-by: Ryder Lee <ryder.lee@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2021-06-19mt76: mt7921: fix reset under the deep sleep is enabledSean Wang3-15/+30
To fix possibly the race to access register between the WiFi reset and the other context that is caused by explicitly cancelling ps_work and wake_work to break PM_STATE consistency. Deep sleep would cause the hardware into the inactive state, so we forcely put device drv_own state before we start to reset. The patch also ignore the reset request when the procedure is in progress to avoid the consecutive WiFi resets. localhost ~ # [ 2932.073966] SError Interrupt on CPU7, code 0xbe000011 [ 2932.073967] CPU: 7 PID: 8761 Comm: kworker/u16:2 Not tainted 5.4.112 #30 [ 2932.073968] Hardware name: MediaTek Asurada rev1 board (DT) [ 2932.073968] Workqueue: phy0 ieee80211_reconfig_filter [mac80211] [ 2932.073969] pstate: 80400089 (Nzcv daIf +PAN -UAO) [ 2932.073969] pc : el1_irq+0x78/0x180 [ 2932.073970] lr : mt76_mmio_rmw+0x30/0x5c [mt76] [ 2932.073970] sp : ffffffc01142bad0 [ 2932.073970] x29: ffffffc01142bc00 x28: ffffff8f96fb1e00 [ 2932.073971] x27: ffffffd2cdc12138 x26: ffffffd2cdaeb018 [ 2932.073972] x25: 0000000000000000 x24: ffffff8fa8e14c08 [ 2932.073973] x23: 0000000080c00009 x22: ffffffd2a5603918 [ 2932.073974] x21: ffffffc01142bc10 x20: 0000007fffffffff [ 2932.073975] x19: 0000000000000000 x18: 0000000000000400 [ 2932.073975] x17: 0000000000000400 x16: ffffffd2cd2b87dc [ 2932.073976] x15: 0000000000000000 x14: 0000000000000000 [ 2932.073977] x13: 0000000000000001 x12: 0000000000000001 [ 2932.073978] x11: 0000000000000001 x10: 000000000010e000 [ 2932.073978] x9 : 0000000000000000 x8 : ffffffc013921404 [ 2932.073979] x7 : 000000b2b5593519 x6 : 0000000000300000 [ 2932.073980] x5 : 0000000000000000 x4 : ffffffc01142bbc8 [ 2932.073980] x3 : 00000000000001f0 x2 : 0000000000000000 [ 2932.073981] x1 : 0000000000021404 x0 : ffffff8fa8e12300 [ 2932.073982] Kernel panic - not syncing: Asynchronous SError Interrupt [ 2932.073983] CPU: 7 PID: 8761 Comm: kworker/u16:2 Not tainted 5.4.112 #30 [ 2932.073983] Hardware name: MediaTek Asurada rev1 board (DT) [ 2932.073984] Workqueue: phy0 ieee80211_reconfig_filter [mac80211] [ 2932.073984] Call trace: [ 2932.073985] dump_backtrace+0x0/0x14c [ 2932.073985] show_stack+0x20/0x2c [ 2932.073985] dump_stack+0xa0/0xf8 [ 2932.073986] panic+0x154/0x360 [ 2932.073986] test_taint+0x0/0x44 [ 2932.073986] arm64_serror_panic+0x78/0x84 [ 2932.073987] do_serror+0x0/0x118 [ 2932.073987] do_serror+0xa4/0x118 [ 2932.073987] el1_error+0x84/0xf8 [ 2932.073988] el1_irq+0x78/0x180 [ 2932.073988] mt76_mmio_rr+0x30/0xf0 [mt76] [ 2932.073988] mt76_mmio_rmw+0x30/0x5c [mt76] [ 2932.073989] mt7921_rmw+0x4c/0x5c [mt7921e] [ 2932.073989] mt7921_configure_filter+0x138/0x160 [mt7921e] [ 2932.073990] ieee80211_configure_filter+0x2f0/0x3e0 [mac80211] [ 2932.073990] ieee80211_reconfig_filter+0x1c/0x28 [mac80211] [ 2932.073990] process_one_work+0x208/0x3c8 [ 2932.073991] worker_thread+0x23c/0x3e8 [ 2932.073991] kthread+0x140/0x17c [ 2932.073992] ret_from_fork+0x10/0x18 [ 2932.074071] SMP: stopping secondary CPUs [ 2932.074071] Kernel Offset: 0x12bc800000 from 0xffffffc010000000 [ 2932.074072] PHYS_OFFSET: 0xfffffff180000000 [ 2932.074072] CPU features: 0x080026,2a80aa18 [ 2932.074072] Memory Limit: none Co-developed-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Lorenzo Bianconi <lorenzo@kernel.org> Signed-off-by: Sean Wang <sean.wang@mediatek.com> Signed-off-by: Felix Fietkau <nbd@nbd.name>

2021-05-15mt76: validate rx A-MSDU subframesFelix Fietkau1-0/+26
Mitigate A-MSDU injection attacks (CVE-2020-24588) by detecting if the destination address of a subframe equals an RFC1042 (i.e., LLC/SNAP) header, and if so dropping the complete A-MSDU frame. This mitigates known attacks, although new (unknown) aggregation-based attacks may remain possible. This defense works because in A-MSDU aggregation injection attacks, a normal encrypted Wi-Fi frame is turned into an A-MSDU frame. This means the first 6 bytes of the first A-MSDU subframe correspond to an RFC1042 header. In other words, the destination MAC address of the first A-MSDU subframe contains the start of an RFC1042 header during an aggregation attack. We can detect this and thereby prevent this specific attack. For details, see Section 7.2 of "Fragment and Forge: Breaking Wi-Fi Through Frame Aggregation and Fragmentation".
