2022-04-09net/mlx5: Unify device IPsec capabilities checkLeon Romanovsky1-2/+5
Merge two different function to one in order to provide coherent picture if the device is IPsec capable or not.

2022-04-09RDMA/mlx5: Drop crypto flow steering APILeon Romanovsky1-8/+5
The mlx5 flow steering crypto API was intended to be used in FPGA devices, which is not supported for years already. The removal of mlx5 crypto FPGA code together with inability to configure encryption keys makes the low steering API completely unusable. So delete the code, so any ESP flow steering requests will fail with not supported error, as it is happening now anyway as no device support this type of API.

git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Jakub Kicinski: "The sprinkling of SPI drivers is because we added a new one and Mark sent us a SPI driver interface conversion pull request. Core ---- - Introduce XDP multi-buffer support, allowing the use of XDP with jumbo frame MTUs and combination with Rx coalescing offloads (LRO). - Speed up netns dismantling (5x) and lower the memory cost a little. Remove unnecessary per-netns sockets. Scope some lists to a netns. Cut down RCU syncing. Use batch methods. Allow netdev registration to complete out of order. - Support distinguishing timestamp types (ingress vs egress) and maintaining them across packet scrubbing points (e.g. redirect). - Continue the work of annotating packet drop reasons throughout the stack. - Switch netdev error counters from an atomic to dynamically allocated per-CPU counters. - Rework a few preempt_disable(), local_irq_save() and busy waiting sections problematic on PREEMPT_RT. - Extend the ref_tracker to allow catching use-after-free bugs. BPF --- - Introduce "packing allocator" for BPF JIT images. JITed code is marked read only, and used to be allocated at page granularity. Custom allocator allows for more efficient memory use, lower iTLB pressure and prevents identity mapping huge pages from getting split. - Make use of BTF type annotations (e.g. __user, __percpu) to enforce the correct probe read access method, add appropriate helpers. - Convert the BPF preload to use light skeleton and drop the user-mode-driver dependency. - Allow XDP BPF_PROG_RUN test infra to send real packets, enabling its use as a packet generator. - Allow local storage memory to be allocated with GFP_KERNEL if called from a hook allowed to sleep. - Introduce fprobe (multi kprobe) to speed up mass attachment (arch bits to come later). - Add unstable conntrack lookup helpers for BPF by using the BPF kfunc infra. - Allow cgroup BPF progs to return custom errors to user space. - Add support for AF_UNIX iterator batching. - Allow iterator programs to use sleepable helpers. - Support JIT of add, and, or, xor and xchg atomic ops on arm64. - Add BTFGen support to bpftool which allows to use CO-RE in kernels without BTF info. - Large number of libbpf API improvements, cleanups and deprecations. Protocols --------- - Micro-optimize UDPv6 Tx, gaining up to 5% in test on dummy netdev. - Adjust TSO packet sizes based on min_rtt, allowing very low latency links (data centers) to always send full-sized TSO super-frames. - Make IPv6 flow label changes (AKA hash rethink) more configurable, via sysctl and setsockopt. Distinguish between server and client behavior. - VxLAN support to "collect metadata" devices to terminate only configured VNIs. This is similar to VLAN filtering in the bridge. - Support inserting IPv6 IOAM information to a fraction of frames. - Add protocol attribute to IP addresses to allow identifying where given address comes from (kernel-generated, DHCP etc.) - Support setting socket and IPv6 options via cmsg on ping6 sockets. - Reject mis-use of ECN bits in IP headers as part of DSCP/TOS. Define dscp_t and stop taking ECN bits into account in fib-rules. - Add support for locked bridge ports (for 802.1X). - tun: support NAPI for packets received from batched XDP buffs, doubling the performance in some scenarios. - IPv6 extension header handling in Open vSwitch. - Support IPv6 control message load balancing in bonding, prevent neighbor solicitation and advertisement from using the wrong port. Support NS/NA monitor selection similar to existing ARP monitor. - SMC - improve performance with TCP_CORK and sendfile() - support auto-corking - support TCP_NODELAY - MCTP (Management Component Transport Protocol) - add user space tag control interface - I2C binding driver (as specified by DMTF DSP0237) - Multi-BSSID beacon handling in AP mode for WiFi. - Bluetooth: - handle MSFT Monitor Device Event - add MGMT Adv Monitor Device Found/Lost events - Multi-Path TCP: - add support for the SO_SNDTIMEO socket option - lots of selftest cleanups and improvements - Increase the max PDU size in CAN ISOTP to 64 kB. Driver API ---------- - Add HW counters for SW netdevs, a mechanism for devices which offload packet forwarding to report packet statistics back to software interfaces such as tunnels. - Select the default NIC queue count as a fraction of number of physical CPU cores, instead of hard-coding to 8. - Expose devlink instance locks to drivers. Allow device layer of drivers to use that lock directly instead of creating their own which always runs into ordering issues in devlink callbacks. - Add header/data split indication to guide user space enabling of TCP zero-copy Rx. - Allow configuring completion queue event size. - Refactor page_pool to enable fragmenting after allocation. - Add allocation and page reuse statistics to page_pool. - Improve Multiple Spanning Trees support in the bridge to allow reuse of topologies across VLANs, saving HW resources in switches. - DSA (Distributed Switch Architecture): - replay and offload of host VLAN entries - offload of static and local FDB entries on LAG interfaces - FDB isolation and unicast filtering New hardware / drivers ---------------------- - Ethernet: - LAN937x T1 PHYs - Davicom DM9051 SPI NIC driver - Realtek RTL8367S, RTL8367RB-VB switch and MDIO - Microchip ksz8563 switches - Netronome NFP3800 SmartNICs - Fungible SmartNICs - MediaTek MT8195 switches - WiFi: - mt76: MediaTek mt7916 - mt76: MediaTek mt7921u USB adapters - brcmfmac: Broadcom BCM43454/6 - Mobile: - iosm: Intel M.2 7360 WWAN card Drivers ------- - Convert many drivers to the new phylink API built for split PCS designs but also simplifying other cases. - Intel Ethernet NICs: - add TTY for GNSS module for E810T device - improve AF_XDP performance - GTP-C and GTP-U filter offload - QinQ VLAN support - Mellanox Ethernet NICs (mlx5): - support xdp->data_meta - multi-buffer XDP - offload tc push_eth and pop_eth actions - Netronome Ethernet NICs (nfp): - flow-independent tc action hardware offload (police / meter) - AF_XDP - Other Ethernet NICs: - at803x: fiber and SFP support - xgmac: mdio: preamble suppression and custom MDC frequencies - r8169: enable ASPM L1.2 if system vendor flags it as safe - macb/gem: ZynqMP SGMII - hns3: add TX push mode - dpaa2-eth: software TSO - lan743x: multi-queue, mdio, SGMII, PTP - axienet: NAPI and GRO support - Mellanox Ethernet switches (mlxsw): - source and dest IP address rewrites - RJ45 ports - Marvell Ethernet switches (prestera): - basic routing offload - multi-chain TC ACL offload - NXP embedded Ethernet switches (ocelot & felix): - PTP over UDP with the ocelot-8021q DSA tagging protocol - basic QoS classification on Felix DSA switch using dcbnl - port mirroring for ocelot switches - Microchip high-speed industrial Ethernet (sparx5): - offloading of bridge port flooding flags - PTP Hardware Clock - Other embedded switches: - lan966x: PTP Hardward Clock - qca8k: mdio read/write operations via crafted Ethernet packets - Qualcomm 802.11ax WiFi (ath11k): - add LDPC FEC type and 802.11ax High Efficiency data in radiotap - enable RX PPDU stats in monitor co-exist mode - Intel WiFi (iwlwifi): - UHB TAS enablement via BIOS - band disablement via BIOS - channel switch offload - 32 Rx AMPDU sessions in newer devices - MediaTek WiFi (mt76): - background radar detection - thermal management improvements on mt7915 - SAR support for more mt76 platforms - MBSSID and 6 GHz band on mt7915 - RealTek WiFi: - rtw89: AP mode - rtw89: 160 MHz channels and 6 GHz band - rtw89: hardware scan - Bluetooth: - mt7921s: wake on Bluetooth, SCO over I2S, wide-band-speed (WBS) - Microchip CAN (mcp251xfd): - multiple RX-FIFOs and runtime configurable RX/TX rings - internal PLL, runtime PM handling simplification - improve chip detection and error handling after wakeup" * tag 'net-next-5.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (2521 commits) llc: fix netdevice reference leaks in llc_ui_bind() drivers: ethernet: cpsw: fix panic when interrupt coaleceing is set via ethtool ice: don't allow to run ice_send_event_to_aux() in atomic ctx ice: fix 'scheduling while atomic' on aux critical err interrupt net/sched: fix incorrect vlan_push_eth dest field net: bridge: mst: Restrict info size queries to bridge ports net: marvell: prestera: add missing destroy_workqueue() in prestera_module_init() drivers: net: xgene: Fix regression in CRC stripping net: geneve: add missing netlink policy and size for IFLA_GENEVE_INNER_PROTO_INHERIT net: dsa: fix missing host-filtered multicast addresses net/mlx5e: Fix build warning, detected write beyond size of field iwlwifi: mvm: Don't fail if PPAG isn't supported selftests/bpf: Fix kprobe_multi test.

In switchdev where TC rules are offloaded to the FDB this can lead to packets being hit in the FDB where without offload they would have been dropped before reaching TC rules in the kernel. Create a drop rule to make sure packets on inactive ports are dropped before reaching the FDB.

2022-02-27net/mlx5: Expose APIs to get/put the mlx5 core deviceYishai Hadas1-0/+3
Expose an API to get the mlx5 core device from a given VF PCI device if mlx5_core is its driver. Upon the get API we stay with the intf_state_mutex locked to make sure that the device can't be gone/unloaded till the caller will complete its job over the device, this expects to be for a short period of time for any flow that the lock is taken. Upon the put API we unlock the intf_state_mutex. The use case for those APIs is the migration flow of a VF over VFIO PCI. In that case the VF doesn't ride on mlx5_core, because the device is driving *two* different PCI devices, the PF owned by mlx5_core and the VF owned by the vfio driver. The mlx5_core of the PF is accessed only during the narrow window of the VF's ioctl that requires its services. This allows the PF driver to be more independent of the VF driver, so long as it doesn't reset the FW.

For mlx5_core/eth kernel user this is what we actually want, but for a devx/rdma user the hidden information is essential and should be propagated up to the caller, thus we convert these commands to use mlx5_cmd_do to return the FW/driver and command outbox status as is, and let the caller decide what to do with it. For kernel callers of mlx5_core_create_{cq/dct} or those who only care about the binary status (FAIL/SUCCESS) they must check status themselves via mlx5_cmd_check() to restore the current behavior. err = mlx5_create_cq(in, out) err = mlx5_cmd_check(err, in, out) if (err) // handle err For DEVX users and those who care about full visibility, They will just propagate the error to user space, and app can check if err == -EREMOTEIO, then outbox.{status,syndrome} are valid. API Note: mlx5_cmd_check() must be used by kernel users since it allows the driver to intercept the command execution status and return a driver simulated status in case of driver induced error handling or reset/recovery flows.

Add mlx5_cmd_do. Unlike mlx5_cmd_exec, this function will not modify or translate outbox.status. The function will return: return = 0: Command was executed, outbox.status == MLX5_CMD_STAT_OK. return = -EREMOTEIO: Executed, outbox.status != MLX5_CMD_STAT_OK. return < 0: Command execution couldn't be performed by FW or driver.

Currently IRQs are requested one by one. To balance spreading IRQs among cpus using such scheme requires remembering cpu mask for the cpus used for a given device. This complicates the IRQ allocation scheme in subsequent patch. Hence, prepare the code for bulk IRQs allocation. This enables spreading IRQs among cpus in subsequent patch.

2021-12-02net/mlx5: Dynamically resize flow counters query bufferAvihai Horon1-0/+4
The flow counters bulk query buffer is allocated once during mlx5_fc_init_stats(). For PFs and VFs this buffer usually takes a little more than 512KB of memory, which is aligned to the next power of 2, to 1MB. For SFs, this buffer is reduced and takes around 128 Bytes. The buffer size determines the maximum number of flow counters that can be queried at a time. Thus, having a bigger buffer can improve performance for users that need to query many flow counters. There are cases that don't use many flow counters and don't need a big buffer (e.g. SFs, VFs). Since this size is critical with large scale, in these cases the buffer size should be reduced. In order to reduce memory consumption while maintaining query performance, change the query buffer's allocation scheme to the following: - First allocate the buffer with small initial size. - If the number of counters surpasses the initial size, resize the buffer to the maximum size. The buffer only grows and isn't shrank, because users with many flow counters don't care about the buffer size and we don't want to add resize overhead if the current number of counters drops. This solution is preferable to the current one, which is less accurate and only addresses SFs.

2021-10-29net/mlx5: Allow skipping counter refresh on creationPaul Blakey1-0/+4
CT creates a counter for each CT rule, and for each such counter, fs_counters tries to queue mlx5_fc_stats_work() work again via mod_delayed_work(0) call to refresh all counters. This call has a large performance impact when reaching high insertion rate and accounts for ~8% of the insertion time when using software steering. Allow skipping the refresh of all counters during counter creation. Change CT to use this refresh skipping for it's counters.
