Merge tag 'net-next-6.17' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Jakub Kicinski: "Core & protocols: - Wrap datapath globals into net_aligned_data, to avoid false sharing - Preserve MSG_ZEROCOPY in forwarding (e.g. out of a container) - Add SO_INQ and SCM_INQ support to AF_UNIX - Add SIOCINQ support to AF_VSOCK - Add TCP_MAXSEG sockopt to MPTCP - Add IPv6 force_forwarding sysctl to enable forwarding per interface - Make TCP validation of whether packet fully fits in the receive window and the rcv_buf more strict. With increased use of HW aggregation a single "packet" can be multiple 100s of kB - Add MSG_MORE flag to optimize large TCP transmissions via sockmap, improves latency up to 33% for sockmap users - Convert TCP send queue handling from tasklet to BH workque - Improve BPF iteration over TCP sockets to see each socket exactly once - Remove obsolete and unused TCP RFC3517/RFC6675 loss recovery code - Support enabling kernel threads for NAPI processing on per-NAPI instance basis rather than a whole device. Fully stop the kernel NAPI thread when threaded NAPI gets disabled.

This is needed for EVPN multi-homing where a neighbor entry for a multi-homed host needs to be synced across all the VTEPs among which the host is multi-homed - Support NUD_PERMANENT for proxy neighbor entries - Add a new queuing discipline for IETF RFC9332 DualQ Coupled AQM - Add sequence numbers to netconsole messages. Unregister netconsole's console when all net targets are removed. Code refactoring. Add a number of selftests - Align IPSec inbound SA lookup to RFC 4301. Only SPI and protocol should be used for an inbound SA lookup - Support inspecting ref_tracker state via DebugFS - Don't force bonding advertisement frames tx to ~333 ms boundaries. Add broadcast_neighbor option to send ARP/ND on all bonded links - Allow providing upcall pid for the 'execute' command in openvswitch - Remove DCCP support from Netfilter's conntrack - Disallow multiple packet duplications in the queuing layer - Prevent use of deprecated iptables code on PREEMPT_RT Driver API: - Support RSS and hashing configuration over ethtool Netlink - Add dedicated ethtool callbacks for getting and setting hashing fields - Add support for power budget evaluation strategy in PSE / Power-over-Ethernet.

189bd9c873f0e49f3fb20372407ccda64114d68a - Merge branch '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue

Wed, 18 Jun 2025 03:50:57 +0200

Merge branch '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queueTony Nguyen says:====================libeth: add libeth_xdp helper libAlexander Lobakin says:Time to add XDP helpers infra to libeth to greatly simplify addingXDP to idpf and iavf, as well as improve and extend XDP in ice andi40e. Any vendor is free to reuse helpers. If this happens, I'm finewith moving the folder of out intel/.The helpers greatly simplify building xdp_buff, running a prog,handling the verdict, implement XDP_TX, .ndo_xdp_xmit, XDP buffercompletion. Same applies to XSk (with XSk xmit instead of.ndo_xdp_xmit, plus stuff like XSk wakeup).They are entirely generic with no HW definitions or assumptions.HW-specific stuff like parsing Rx desc / filling Tx desc is passedfrom the driver as inline callbacks.For now, key assumptions that optimize performance / avoid codebloat, but might not fit every driver in driver/net/: * netmem holding the buffers are always order-0; * driver has separate XDP Tx queues, doesn't use stack queues for that. For best efficiency, you may want to have nr_cpu_ids XDP queues, but less (queue sharing) is also supported; * XDP Tx queues are interrupt-less and use "lazy" cleaning only when there are less than 1/4 free Tx descriptors of the queue size; * main target platforms are 64-bit, although 32-bit is also fully supported, but the code might be not as optimized for them.Library code already supports multi-buffer for all kinds of Tx andboth header split and no split for Rx and Tx. Frags can come fromdevmem/io_uring etc., direct `struct page *` is used only for headerbuffers for which it's always true.Drivers are free to pass their own Rx hints and XSK xmit hints ops.XDP_TX and ndo_xdp_xmit use onstack bulk for the frames to be sentand send them by batches of 16 buffers. This eats ~280 bytes on thestack, but gives good boosts and allow to greatly optimize the mainsending function leaving it without any error/exception paths.XSk xmit fills Tx descriptors in the loop unrolled by 8. This wasproven to improve perf on ice and i40e. XDP_TX and ndo_xdp_xmitdoesn't use unrolling as I wasn't able to get any improvements inthose scenenarios from this, while +1 Kb for their sending functionsfor nothing doesn't sound reasonable.XSk wakeup, instead of traditionally used "SW interrupts" providedby NICs, uses IPI to schedule NAPI on the CPU corresponding to thegiven queue pair. It gives better control over CPU distribution andin general performs way better than "SW interrupts", plus allows usto not pass any HW-specific callbacks there.The code is built the way that all callbacks passed from driversget inlined; in general, most of hotpath gets inlined. Everythingslow/exception lands to .c files in the libeth folder, doesn'tcreate copies in the drivers themselves and doesn't overloathotpath.Sure, inlining means that hotpath will be compiled into every driverthat uses the lib, but the core code is written in one place, so nocopying of bugs happens. Fixed once -- works everywhere.The last commit might look like sorta hack, but it gives really goodboosts and decreases object code size, plus there are checks thatall those wider accesses are fully safe, so I don't feel anythingbad about it.An example of using libeth_xdp can be found either on my GitHub oron the mailing lists here ("XDP for idpf"). Macros for buildingdriver XDP functions lead to that some implementations (XDP_TX,ndo_xdp_xmit etc.) consist of really only a few lines.* '200GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/tnguy/next-queue: libeth: xdp, xsk: access adjacent u32s as u64 where applicable libeth: xsk: add XSkFQ refill and XSk wakeup helpers libeth: xsk: add XSk Rx processing support libeth: xsk: add XSk xmit functions libeth: xsk: add XSk XDP_TX sending helpers libeth: xdp: add RSS hash hint and XDP features setup helpers libeth: xdp: add templates for building driver-side callbacks libeth: xdp: add XDP prog run and verdict result handling libeth: xdp: add helpers for preparing/processing &libeth_xdp_buff libeth: xdp: add XDPSQ cleanup timers libeth: xdp: add XDPSQ locking helpers libeth: xdp: add XDPSQE completion helpers libeth: xdp: add .ndo_xdp_xmit() helpers libeth: xdp: add XDP_TX buffers sending libeth: support native XDP and register memory model libeth: convert to netmem libeth, libie: clean symbol exports up a little====================Link: https://patch.msgid.link/20250616201639.710420-1-anthony.l.nguyen@intel.comSigned-off-by: Jakub Kicinski List of files: /linux/drivers/net/ethernet/intel/libeth/Kconfig

libeth: xsk: add XSk XDP_TX sending helpersAdd Xsk counterparts for XDP_TX buffer sending and completion.The same base structures and functions used from the libeth_xdp core,with adjustments to that XSk Rx always operates on &xdp_buff_xsk forboth head and frags.

8591c3afe8882a00d9070daf78c384b003b596f3 - libeth: xdp: add XDP_TX buffers sending

Thu, 12 Jun 2025 18:02:21 +0200

libeth: xdp: add XDP_TX buffers sendingStart adding XDP-specific code to libeth, namely handling XDP_TX buffers(only sending).The idea is that we accumulate up to 16 buffers on the stack, then,if either the limit is reached or the polling is finished, flush themat once with only one XDPSQ cleaning (if needed). The main sendingfunction will be aware of the sending budget and already have all theinfo to send the buffers, so it can't fail.Drivers need to provide 2 inline callbacks to the main sending function:for cleaning an XDPSQ and for filling descriptors; the library codetakes care of the rest.Note that unlike the generic code, multi-buffer support is not wrappedhere with unlikely() to not hurt header split setups.&libeth_xdp_buff is a simple extension over &xdp_buff which has a directpointer to the corresponding Rx descriptor (and, luckily, precisely 1 CLsize and 16-byte alignment on x86_64).Suggested-by: Maciej Fijalkowski # xmit logicSigned-off-by: Alexander Lobakin Signed-off-by: Tony Nguyen List of files: /linux/drivers/net/ethernet/intel/libeth/Kconfig
