2023-02-15virtio-blk: add support for zoned block devicesDmitry Fomichev
This patch adds support for Zoned Block Devices (ZBDs) to the kernel virtio-blk driver. The patch accompanies the virtio-blk ZBD support draft that is now being proposed for standardization. The latest version of the draft is linked at https://github.com/oasis-tcs/virtio-spec/issues/143 . The QEMU zoned device code that implements these protocol extensions has been developed by Sam Li and it is currently in review at the QEMU mailing list. A number of virtblk request structure changes has been introduced to accommodate the functionality that is specific to zoned block devices and, most importantly, make room for carrying the Zoned Append sector value from the device back to the driver along with the request status. The zone-specific code in the patch is heavily influenced by NVMe ZNS code in drivers/nvme/host/zns.c, but it is simpler because the proposed virtio ZBD draft only covers the zoned device features that are relevant to the zoned functionality provided by Linux block layer. includes the following fixup: virtio-blk: fix probe without CONFIG_BLK_DEV_ZONED When building without CONFIG_BLK_DEV_ZONED, VIRTIO_BLK_F_ZONED is excluded from array of driver features. As a result virtio_has_feature panics in virtio_check_driver_offered_feature since that by design verifies that a feature we are checking for is listed in the feature array. To fix, replace the call to virtio_has_feature with a stub.

2023-02-14wifi: mac80211: add a workaround for receiving non-standard mesh A-MSDUFelix Fietkau
At least ath10k and ath11k supported hardware (maybe more) does not implement mesh A-MSDU aggregation in a standard compliant way. 802.11-2020 9.3.2.2.2 declares that the Mesh Control field is part of the A-MSDU header (and little-endian). As such, its length must not be included in the subframe length field. Hardware affected by this bug treats the mesh control field as part of the MSDU data and sets the length accordingly. In order to avoid packet loss, keep track of which stations are affected by this and take it into account when converting A-MSDU to 802.3 + mesh control packets.

2023-02-14wifi: mac80211: fix receiving A-MSDU frames on mesh interfacesFelix Fietkau
The current mac80211 mesh A-MSDU receive path fails to parse A-MSDU packets on mesh interfaces, because it assumes that the Mesh Control field is always directly after the 802.11 header. 802.11-2020 9.3.2.2.2 Figure 9-70 shows that the Mesh Control field is actually part of the A-MSDU subframe header. This makes more sense, since it allows packets for multiple different destinations to be included in the same A-MSDU, as long as RA and TID are still the same. Another issue is the fact that the A-MSDU subframe length field was apparently accidentally defined as little-endian in the standard. In order to fix this, the mesh forwarding path needs happen at a different point in the receive path. ieee80211_data_to_8023_exthdr is changed to ignore the mesh control field and leave it in after the ethernet header. This also affects the source/dest MAC address fields, which now in the case of mesh point to the mesh SA/DA. ieee80211_amsdu_to_8023s is changed to deal with the endian difference and to add the Mesh Control length to the subframe length, since it's not covered by the MSDU length field. With these changes, the mac80211 will get the same packet structure for converted regular data packets and unpacked A-MSDU subframes. The mesh forwarding checks are now only performed after the A-MSDU decap. For locally received packets, the Mesh Control header is stripped away. For forwarded packets, a new 802.11 header gets added.

2023-02-14wifi: nl80211: validate and configure puncturing bitmapAloka Dixit
- New feature flag, NL80211_EXT_FEATURE_PUNCT, to advertise driver support for preamble puncturing in AP mode. - New attribute, NL80211_ATTR_PUNCT_BITMAP, to receive a puncturing bitmap from the userspace during AP bring up (NL80211_CMD_START_AP) and channel switch (NL80211_CMD_CHANNEL_SWITCH) operations. Each bit corresponds to a 20 MHz channel in the operating bandwidth, lowest bit for the lowest channel. Bit set to 1 indicates that the channel is punctured. Higher 16 bits are reserved. - New members added to structures cfg80211_ap_settings and cfg80211_csa_settings to propagate the bitmap to the driver after validation.

Add new parameters in struct station_info to provide below information in cfg80211_new_sta() call: - MLO link ID of the AP, with which station completed (re)association. This is applicable for both MLO and non-MLO station connections when the AP affiliated with an MLD. - Station's MLD address if the connection is MLO capable. - (Re)Association Response IEs sent to the station.

2023-02-14wifi: cfg80211: Authentication offload to user space for MLO connection in ↵Veerendranath Jakkam
STA mode Currently authentication request event interface doesn't have support to indicate the user space whether it should enable MLO or not during the authentication with the specified AP. But driver needs such capability since the connection is MLO or not decided by the driver in case of SME offload to the driver. Add support for driver to indicate MLD address of the AP in authentication offload request to inform user space to enable MLO during authentication process. Driver shall look at NL80211_ATTR_MLO_SUPPORT flag capability in NL80211_CMD_CONNECT to know whether the user space supports enabling MLO during the authentication offload. User space should enable MLO during the authentication only when it receives the AP MLD address in authentication offload request. User space shouldn't enable MLO if the authentication offload request doesn't indicate the AP MLD address even if the AP is MLO capable. When MLO is enabled, user space should use the MAC address of the interface (on which driver sent request) as self MLD address. User space and driver to use MLD addresses in RA, TA and BSSID fields of the frames between them, and driver translates the MLD addresses to/from link addresses based on the link chosen for the authentication.

2023-02-14net/mlx5e: TC, support per action statsOz Shlomo
Extend the action stats callback implementation to update stats for actions that are associated with hw counters. Note that the callback may be called from tc action utility or from tc flower. Both apis expect the driver to return the stats difference from the last update. As such, query the raw counter value and maintain the diff from the last api call in the tc layer, instead of the fs_core layer.

2023-02-14net/sched: support per action hw statsOz Shlomo
There are currently two mechanisms for populating hardware stats: 1. Using flow_offload api to query the flow's statistics. The api assumes that the same stats values apply to all the flow's actions. This assumption breaks when action drops or jumps over following actions. 2. Using hw_action api to query specific action stats via a driver callback method. This api assures the correct action stats for the offloaded action, however, it does not apply to the rest of the actions in the flow's actions array. Extend the flow_offload stats callback to indicate that a per action stats update is required. Use the existing flow_offload_action api to query the action's hw stats. In addition, currently the tc action stats utility only updates hw actions. Reuse the existing action stats cb infrastructure to query any action stats.
