2021-12-08rtw89: add const in the cast of le32_get_bits()Ping-Ke Shih
Add 'const' to be clear that this is a read-only access, and this patch doesn't change logic at all.

2021-12-08mt76: mt7921: fix build regressionArnd Bergmann
After mt7921s got added, there are two possible build problems: a) mt7921s does not get built at all if mt7921e is not also enabled b) there is a link error when mt7921e is a loadable module, but mt7921s configured as built-in: ERROR: modpost: "mt7921_mac_sta_add" [drivers/net/wireless/mediatek/mt76/mt7921/mt7921e.ko] undefined!

2021-12-08brcmsmac: rework LED dependenciesArnd Bergmann
This is now the only driver that selects the LEDS_CLASS framework, which is normally user-selectable. While it doesn't strictly cause a bug, rework the Kconfig logic to be more consistent with what other drivers do, and only enable LED support in brcmsmac if the dependencies are all there, rather than using 'select' to enable what it needs.

2021-12-08iwlwifi: fix LED dependenciesArnd Bergmann
The dependencies for LED configuration are highly inconsistent and too complicated at the moment. One of the results is a randconfig failure I get very rarely when LEDS_CLASS is in a loadable module, but the wireless core is built-in: WARNING: unmet direct dependencies detected for MAC80211_LEDS Depends on [n]: NET [=y] && WIRELESS [=y] && MAC80211 [=y] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=MAC80211 [=y]) Selected by [m]: - IWLEGACY [=m] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y] - IWLWIFI_LEDS [=y] && NETDEVICES [=y] && WLAN [=y] && WLAN_VENDOR_INTEL [=y] && IWLWIFI [=m] && (LEDS_CLASS [=m]=y || LEDS_CLASS [=m]=IWLWIFI [=m]) && (IWLMVM [=m] || IWLDVM [=m]) aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_register_led': led.c:(.text+0x60): undefined reference to `led_classdev_register_ext' aarch64-linux-ld: drivers/net/wireless/ath/ath5k/led.o: in function `ath5k_unregister_leds': led.c:(.text+0x200): undefined reference to `led_classdev_unregister' For iwlwifi, the dependency is wrong, since this config prevents the MAC80211_LEDS code from being part of a built-in MAC80211 driver. For iwlegacy, this is worse because the driver tries to force-enable the other subsystems, which is both a layering violation and a bug because it will still fail with MAC80211=y and IWLEGACY=m, leading to LEDS_CLASS being a module as well. The actual link failure in the ath5k driver is a result of MAC80211_LEDS being enabled but not usable. With the Kconfig logic fixed in the Intel drivers, the ath5k driver works as expected again.

While running stress tests in roaming scenarios (switching ap's every 5 seconds, we discovered a issue which leads to tx hangings of exactly 5 seconds while or after scanning for new accesspoints. We found out that this hanging is triggered by ath10k_mac_wait_tx_complete since the empty_tx_wq was not wake when the num_tx_pending counter reaches zero. To fix this, we simply move the wake_up call to htt_tx_dec_pending, since this call was missed on several locations within the ath10k code.

2021-12-08ath11k: avoid deadlock by change ieee80211_queue_work for regd_update_workWen Gong
When enable debug config, it print below warning while shut down wlan interface shuh as run "ifconfig wlan0 down". The reason is because ar->regd_update_work is ran once, and it is will call wiphy_lock(ar->hw->wiphy) in function ath11k_regd_update() which is running in workqueue of ieee80211_local queued by ieee80211_queue_work(). Another thread from "ifconfig wlan0 down" will also accuqire the lock by wiphy_lock(sdata->local->hw.wiphy) in function ieee80211_stop(), and then it call ieee80211_stop_device() to flush_workqueue(local->workqueue), this will wait the workqueue of ieee80211_local finished. Then deadlock will happen easily if the two thread run meanwhile. Below warning disappeared after this change.

2021-12-07net: fec: only clear interrupt of handling queue in fec_enet_rx_queue()Joakim Zhang
Background: We have a customer is running a Profinet stack on the 8MM which receives and responds PNIO packets every 4ms and PNIO-CM packets every 40ms. However, from time to time the received PNIO-CM package is "stock" and is only handled when receiving a new PNIO-CM or DCERPC-Ping packet (tcpdump shows the PNIO-CM and the DCERPC-Ping packet at the same time but the PNIO-CM HW timestamp is from the expected 40 ms and not the 2s delay of the DCERPC-Ping). After debugging, we noticed PNIO, PNIO-CM and DCERPC-Ping packets would be handled by different RX queues. The root cause should be driver ack all queues' interrupt when handle a specific queue in fec_enet_rx_queue(). The blamed patch is introduced to receive as much packets as possible once to avoid interrupt flooding. But it's unreasonable to clear other queues'interrupt when handling one queue, this patch tries to fix it.

After the below patch, the conntrack attached to skb is set to "notrack" in the context of vrf device, for locally generated packets. But this is true only when the default qdisc is set to the vrf device. When changing the qdisc, notrack is not set anymore. In fact, there is a shortcut in the vrf driver, when the default qdisc is set, see commit dcdd43c41e60 ("net: vrf: performance improvements for IPv4") for more details. This patch ensures that the behavior is always the same, whatever the qdisc is. To demonstrate the difference, a new test is added in conntrack_vrf.sh.

2021-12-07ice: fix adding different tunnelsMichal Swiatkowski
Adding filters with the same values inside for VXLAN and Geneve causes HW error, because it looks exactly the same. To choose between different type of tunnels new recipe is needed. Add storing tunnel types in creating recipes function and start checking it in finding function. Change getting open tunnels function to return port on correct tunnel type. This is needed to copy correct port to dummy packet. Block user from adding enc_dst_port via tc flower, because VXLAN and Geneve filters can be created only with destination port which was previously opened.

2021-12-07ice: fix choosing UDP header typeMichal Swiatkowski
In tunnels packet there can be two UDP headers: - outer which for hw should be mark as ICE_UDP_OF - inner which for hw should be mark as ICE_UDP_ILOS or as ICE_TCP_IL if inner header is of TCP type In none tunnels packet header can be: - UDP, which for hw should be mark as ICE_UDP_ILOS - TCP, which for hw should be mark as ICE_TCP_IL Change incorrect ICE_UDP_OF for none tunnel packets to ICE_UDP_ILOS. ICE_UDP_OF is incorrect for none tunnel packets and setting it leads to error from hw while adding this kind of recipe. In summary, for tunnel outer port type should always be set to ICE_UDP_OF, for none tunnel outer and tunnel inner it should always be set to ICE_UDP_ILOS.

2021-12-07ice: ignore dropped packets during initJesse Brandeburg
If the hardware is constantly receiving unicast or broadcast packets during driver load, the device previously counted many GLV_RDPC (VSI dropped packets) events during init. This causes confusing dropped packet statistics during driver load. The dropped packets counter incrementing does stop once the driver finishes loading. Avoid this problem by baselining our statistics at the end of driver open instead of the end of probe.

2021-12-07ice: Fix problems with DSCP QoS implementationDave Ertman
The patch that implemented DSCP QoS implementation removed a bandwidth check that was used to check for a specific condition caused by some corner cases. This check should not of been removed. The same patch also added a check for when the DCBx state could be changed in relation to DSCP, but the check was erroneously added nested in a check for CEE mode, which made the check useless. Fix these problems by re-adding the bandwidth check and relocating the DSCP mode check earlier in the function that changes DCBx state in the driver.

2021-12-07iwlwifi: work around reverse dependency on MEIArnd Bergmann
If the iwlmei code is a loadable module, the main iwlwifi driver cannot be built-in: x86_64-linux-ld: drivers/net/wireless/intel/iwlwifi/pcie/trans.o: in function `iwl_pcie_prepare_card_hw': trans.c:(.text+0x4158): undefined reference to `iwl_mei_is_connected' Unfortunately, Kconfig enforces the opposite, forcing the MEI driver to not be built-in if iwlwifi is a module. To work around this, decouple iwlmei from iwlwifi and add the dependency in the other direction.
