For the NL80211_REGDOM_SET_BY_USER hint from cfg80211, it set the new alpha2 code to ath11k, then ath11k send WMI_SET_INIT_COUNTRY_CMDID to firmware for all chips currently. When test with WCN6855/QCA6390 chips, this WMI CMD leads firmware crash. For AP based chips(ipq8074/qcn9074), WMI_SET_INIT_COUNTRY_CMDID is used to send to firmware, for STATION based chips(WCN6855/QCA6390), it need to use another WMI CMD WMI_SET_CURRENT_COUNTRY_CMDID. Add flag current_cc_support in hardware parameters, it is used to distinguish AP/STA platform. After that, the firmware will work normal and the regulatory feature works well for QCA6390/WCN6855.

Syzbot reported 2 KMSAN bugs in ath9k. All of them are caused by missing field initialization. In htc_connect_service() svc_meta_len and pad are not initialized. Based on code it looks like in current skb there is no service data, so simply initialize svc_meta_len to 0. htc_issue_send() does not initialize htc_frame_hdr::control array. Based on firmware code, it will initialize it by itself, so simply zero whole array to make KMSAN happy Fail logs: BUG: KMSAN: kernel-usb-infoleak in usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 usb_submit_urb+0x6c1/0x2aa0 drivers/usb/core/urb.c:430 hif_usb_send_regout drivers/net/wireless/ath/ath9k/hif_usb.c:127 [inline] hif_usb_send+0x5f0/0x16f0 drivers/net/wireless/ath/ath9k/hif_usb.c:479 htc_issue_send drivers/net/wireless/ath/ath9k/htc_hst.c:34 [inline] htc_connect_service+0x143e/0x1960 drivers/net/wireless/ath/ath9k/htc_hst.c:275 ...

Zerocopy benchmarks over dummy showed ~5% tx/s improvement, should be similar for small payload non-zc cases. The performance comes from killing 4 atomics and a couple of big struct memcpy/memset. 1/10 removes a pair of atomics on dst refcounting for cork->skb setup, 9/10 saves another pair on cork init. 5/10 and 8/10 kill extra 88B memset and memcpy respectively. ==================== Link: https://lore.kernel.org/r/cover.1643243772.git.asml.silence@gmail.comSigned-off-by:

udpv6_sendmsg() doesn't need dst after calling ip6_make_skb(), so instead of taking an additional reference inside ip6_setup_cork() and releasing the initial one afterwards, we can hand over a reference into ip6_make_skb() saving two atomics. The only other user of ip6_setup_cork() is ip6_append_data() and it requires an extra dst_hold(). Signed-off-by:

udpv6_sendmsg() first initialises an on-stack 88B struct flowi6 and then copies it into cork, which is expensive. Avoid the copy in corkless case by initialising on-stack cork->fl directly. The main part is a couple of lines under !corkreq check. The rest converts fl6 variable to be a pointer. Signed-off-by:

Another preparation patch. inet_cork_full already contains a field for iflow, so we can avoid passing a separate struct iflow6 into __ip6_append_data() and ip6_make_skb(), and use the flow stored in inet_cork_full. Make sure callers set cork->fl, i.e. we init it in ip6_append_data() and before calling ip6_make_skb(). Signed-off-by:

In Spectrum-2 and later ASICs, each TCAM region has a default action that is executed in case a packet did not match any rule in the region. The location of the action in the database (KVDL) is computed by adding the region's index to a base value. Some TCAM regions are not exposed to the host and used internally by the device. Allocate KVDL entries for the default actions of these regions to avoid the host from overwriting them. With mlxsw, lookups in the internal regions are not currently performed, but it is a good practice not to overwrite their default actions. Signed-off-by:

When processing events generated by the device's firmware, the driver protects itself from events reported for non-existent local ports, but not for the CPU port (local port 0), which exists, but does not have all the fields as any local port. This can result in a NULL pointer dereference when trying access 'struct mlxsw_sp_port' fields which are not initialized for CPU port. Commit 63b08b1f ("mlxsw: spectrum: Protect driver from buggy firmware") already handled such issue by bailing early when processing a PUDE event reported for the CPU port. Generalize the approach by moving the check to a common function and making use of it in all relevant places. Signed-off-by:

Saeed Mahameed says: ==================== mlx5-updates-2022-01-27 1) Dima, adds an internal mlx5 steering callback per steering provider (FW vs SW steering), to advertise steering capabilities implemented by each module, this helps upper modules in mlx5 to know what is supported and what's not without the need to tell what is the underlying steering mode. 2nd patch is the usecase where this interface is used to implement Vlan Push/pop for uplink with SW steering, where in FW mode it's not supported yet. 2) Roi Dayan improves code readability and maintainability as preparation step for multi attribute instance per flow in mlx5 TC module Currently the mlx5_flow object contains a single mlx5_attr instance. However, multi table actions (e.g. CT) instantiate multiple attr instances. This is a refactoring series in a preparation to support multiple attribute instances per flow. The commits prepare functions to get attr instance instead of using flow->attr and also using attr->flags if the flag is more relevant to be attr flag and not a flow flag considering there will be multiple attr instances. i.e. CT and SAMPLE flags. * tag 'mlx5-updates-2022-01-27' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux: net/mlx5: VLAN push on RX, pop on TX net/mlx5: Introduce software defined steering capabilities net/mlx5: Remove unused TIR modify bitmask enums net/mlx5e: CT, Remove redundant flow args from tc ct calls net/mlx5e: TC, Store mapped tunnel id on flow attr net/mlx5e: Test CT and SAMPLE on flow attr net/mlx5e: Refactor eswitch attr flags to just attr flags net/mlx5e: CT, Don't set flow flag CT for ct clear flow net/mlx5e: TC, Hold sample_attr on stack instead of pointer net/mlx5e: TC, Reject rules with multiple CT actions net/mlx5e: TC, Refactor mlx5e_tc_add_flow_mod_hdr() to get flow attr net/mlx5e: TC, Pass attr to tc_act can_offload() net/mlx5e: TC, Split pedit offloads verify from alloc_tc_pedit_action() net/mlx5e: TC, Move pedit_headers_action to parse_attr net/mlx5e: Move counter creation call to alloc_flow_attr_counter() net/mlx5e: Pass attr arg for attaching/detaching encaps net/mlx5e: Move code chunk setting encap dests into its own function ==================== Link: https://lore.kernel.org/r/20220127204007.146300-1-saeed@kernel.orgSigned-off-by:

Some older NIC hardware isn't capable of doing VLAN push on RX and pop on TX. A workaround has been added in software to support it, but it has a performance penalty since it requires a hairpin + loopback. There's no such limitation with the newer NICs, so no need to pay the price of the w/a. With this change the software w/a is disabled for certain HW versions and steering modes that support it.

There are two different internal steering modes, abstracted from the rest of the driver. In order to keep upper layer of the driver agnostic to the differences in capabilities of the steering modes, this patch introduces mlx5_fs_get_capabilities() API to check if a certain software defined capability is supported. It differs from the capabilities exposed by the hardware, as it takes into account the flow steering mode (SMFS/DMFS) currently enabled. This implementation supports only two capability flags: MLX5_FLOW_STEERING_CAP_VLAN_PUSH_ON_RX MLX5_FLOW_STEERING_CAP_VLAN_POP_ON_TX They map to DR_ACTION_STATE_PUSH_VLAN and DR_ACTION_STATE_POP_VLAN actions, implemented in SW steering earlier in commit f5e22be5 ("net/mlx5: DR, Split modify VLAN state to separate pop/push states"). Which enables using of pop/push vlan without restrictions, e.g. doing vlan pop on TX and RX, compared to FW steering that supports only vlan pop on RX and push on TX. Other capabilities can be added in the future. Signed-off-by:

ct clear action is a normal flow with a modify header for registers to 0. there is no need for any special handling in tc_ct.c. Parsing of ct clear action still allocates mod acts to set 0 on the registers and the driver continue to add a normal rule with modify hdr context. Signed-off-by:

In later commit we are going to instantiate multiple attr instances for flow instead of single attr. Parsing TC sample allocates a new memory but there is no symmetric cleanup in the infrastructure. To avoid asymmetric alloc/free use sample_attr as part of the flow attr and not allocated and held as a pointer. This will avoid a cleanup leak when sample action is not on the first attr.

The driver doesn't support multiple CT actions. Multiple CT clear actions are ok as they are redundant also with another CT actions. Signed-off-by:
