2022-07-06octeontx2-af: Use hashed field in MCAM keyRatheesh Kannoth
CN10KB variant of CN10K series of silicons supports a new feature where in a large protocol field (eg 128bit IPv6 DIP) can be condensed into a small hashed 32bit data. This saves a lot of space in MCAM key and allows user to add more protocol fields into the filter. A max of two such protocol data can be hashed. This patch adds support for hashing IPv6 SIP and/or DIP. Signed-off-by: Suman Ghosh <sumang@marvell.com> Signed-off-by: Ratheesh Kannoth <rkannoth@marvell.com> Signed-off-by: David S.

2022-07-02net: add skb_[inner_]tcp_all_headers helpersEric Dumazet
Most drivers use "skb_transport_offset(skb) + tcp_hdrlen(skb)" to compute headers length for a TCP packet, but others use more convoluted (but equivalent) ways. Add skb_tcp_all_headers() and skb_inner_tcp_all_headers() helpers to harmonize this a bit. Signed-off-by: Eric Dumazet <edumazet@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2022-05-02octeontx2-pf: replace bitmap_weight with bitmap_empty where appropriateYury Norov
In some places, octeontx2 code calls bitmap_weight() to check if any bit of a given bitmap is set. It's better to use bitmap_empty() in that case because bitmap_empty() stops traversing the bitmap as soon as it finds first set bit, while bitmap_weight() counts all bits unconditionally.

2022-04-06prestera: acl: add action hw_stats supportVolodymyr Mytnyk
Currently, when user adds a tc action and the action gets offloaded, the user expects the HW stats to be counted also. This limits the amount of supported offloaded filters, as HW counter resources may be quite limited. Without counter assigned, the HW is capable to carry much more filters. To resolve the issue above, the following types of HW stats are offloaded and supported by the driver: any - current default, user does not care about the type. delayed - polled from HW periodically. disabled - no HW stats needed. immediate - not supported. Example: tc filter add dev PORT ingress proto ip flower skip_sw ip_proto 0x11 \ action drop tc filter add dev PORT ingress proto ip flower skip_sw ip_proto 0x12 \ action drop hw_stats disabled tc filter add dev sw1p1 ingress proto ip flower skip_sw ip_proto 0x14 \ action drop hw_stats delayed Signed-off-by: Volodymyr Mytnyk <vmytnyk@marvell.com> Link: https://lore.kernel.org/r/1649164814-18731-1-git-send-email-volodymyr.mytnyk@plvision.eu Signed-off-by: Jakub Kicinski <kuba@kernel.org>

There is often not a MAC address available in an EEPROM accessible by Linux with Marvell devices. Instead the bootload has the MAC address and directly programs it into the hardware. So don't consider an error from of_get_mac_address() has fatal. However, the check was added for the case where there is a MAC address in an the EEPROM, but the EEPROM has not probed yet, and -EPROBE_DEFER is returned. In that case the error should be returned.

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.
