Thu, 02 Oct 2025 22:17:01 +0000

Merge tag 'net-next-6.18' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextPull networking updates from Paolo Abeni: "Core & protocols: - Improve drop account scalability on NUMA hosts for RAW and UDP sockets and the backlog, almost doubling the Pps capacity under DoS - Optimize the UDP RX performance under stress, reducing contention, revisiting the binary layout of the involved data structs and implementing NUMA-aware locking. This improves UDP RX performance by an additional 50%, even more under extreme conditions - Add support for PSP encryption of TCP connections; this mechanism has some similarities with IPsec and TLS, but offers superior HW offloads capabilities - Ongoing work to support Accurate ECN for TCP. AccECN allows more than one congestion notification signal per RTT and is a building block for Low Latency, Low Loss, and Scalable Throughput (L4S) - Reorganize the TCP socket binary layout for data locality, reducing the number of touched cachelines in the fastpath - Refactor skb deferral free to better scale on large multi-NUMA hosts, this improves TCP and UDP RX performances significantly on such HW - Increase the default socket memory buffer limits from 256K to 4M to better fit modern link speeds - Improve handling of setups with a large number of nexthop, making dump operating scaling linearly and avoiding unneeded synchronize_rcu() on delete - Improve bridge handling of VLAN FDB, storing a single entry per bridge instead of one entry per port; this makes the dump order of magnitude faster on large switches - Restore IP ID correctly for encapsulated packets at GSO segmentation time, allowing GRO to merge packets in more scenarios - Improve netfilter matching performance on large sets - Improve MPTCP receive path performance by leveraging recently introduced core infrastructure (skb deferral free) and adopting recent TCP autotuning changes - Allow bridges to redirect to a backup port when the bridge port is administratively down - Introduce MPTCP 'laminar' endpoint that con be used only once per connection and simplify common MPTCP setups - Add RCU safety to dst->dev, closing a lot of possible races - A significant crypto library API for SCTP, MPTCP and IPv6 SR, reducing code duplication - Supports pulling data from an skb frag into the linear area of an XDP buffer Things we sprinkled into general kernel code: - Generate netlink documentation from YAML using an integrated YAML parser Driver API: - Support using IPv6 Flow Label in Rx hash computation and RSS queue selection - Introduce API for fetching the DMA device for a given queue, allowing TCP zerocopy RX on more H/W setups - Make XDP helpers compatible with unreadable memory, allowing more easily building DevMem-enabled drivers with a unified XDP/skbs datapath - Add a new dedicated ethtool callback enabling drivers to provide the number of RX rings directly, improving efficiency and clarity in RX ring queries and RSS configuration - Introduce a burst period for the health reporter, allowing better handling of multiple errors due to the same root cause - Support for DPLL phase offset exponential moving average, controlling the average smoothing factor Device drivers: - Add a new Huawei driver for 3rd gen NIC (hinic3) - Add a new SpacemiT driver for K1 ethernet MAC - Add a generic abstraction for shared memory communication devices (dibps) - Ethernet high-speed NICs: - nVidia/Mellanox: - Use multiple per-queue doorbell, to avoid MMIO contention issues - support adjacent functions, allowing them to delegate their SR-IOV VFs to sibling PFs - support RSS for IPSec offload - support exposing raw cycle counters in PTP and mlx5 - support for disabling host PFs. - Intel (100G, ice, idpf): - ice: support for SRIOV VFs over an Active-Active link aggregate - ice: support for firmware logging via debugfs - ice: support for Earliest TxTime First (ETF) hardware offload - idpf: support basic XDP functionalities and XSk - Broadcom (bnxt): - support Hyper-V VF ID - dynamic SRIOV resource allocations for RoCE - Meta (fbnic): - support queue API, zero-copy Rx and Tx - support basic XDP functionalities - devlink health support for FW crashes and OTP mem corruptions - expand hardware stats coverage to FEC, PHY, and Pause - Wangxun: - support ethtool coalesce options - support for multiple RSS contexts - Ethernet virtual: - Macsec: - replace custom netlink attribute checks with policy-level checks - Bonding: - support aggregator selection based on port priority - Microsoft vNIC: - use page pool fragments for RX buffers instead of full pages to improve memory efficiency - Ethernet NICs consumer, and embedded: - Qualcomm: support Ethernet function for IPQ9574 SoC - Airoha: implement wlan offloading via NPU - Freescale - enetc: add NETC timer PTP driver and add PTP support - fec: enable the Jumbo frame support for i.MX8QM - Renesas (R-Car S4): - support HW offloading for layer 2 switching - support for RZ/{T2H, N2H} SoCs - Cadence (macb): support TAPRIO traffic scheduling - TI: - support for Gigabit ICSS ethernet SoC (icssm-prueth) - Synopsys (stmmac): a lot of cleanups - Ethernet PHYs: - Support 10g-qxgmi phy-mode for AQR412C, Felix DSA and Lynx PCS driver - Support bcm63268 GPHY power control - Support for Micrel lan8842 PHY and PTP - Support for Aquantia AQR412 and AQR115 - CAN: - a large CAN-XL preparation work - reorganize raw_sock and uniqframe struct to minimize memory usage - rcar_canfd: update the CAN-FD handling - WiFi: - extended Neighbor Awareness Networking (NAN) support - S1G channel representation cleanup - improve S1G support - WiFi drivers: - Intel (iwlwifi): - major refactor and cleanup - Broadcom (brcm80211): - support for AP isolation - RealTek (rtw88/89) rtw88/89: - preparation work for RTL8922DE support -

Merge branch 'selftest-packetdrill-import-tfo-server-tests'Kuniyuki Iwashima says:====================selftest: packetdrill: Import TFO server tests.The series imports 15 TFO server tests from google/packetdrill andadds 2 more tests.The repository has two versions of tests for most scenarios; one usesthe non-experimental option (34), and the other uses the experimentaloption (255) with 0xF989.Basically, we only import the non-experimental version of tests, andfor the experimental option, tcp_fastopen_server_experimental_option.pktis added.The following tests are not (yet) imported: * icmp-baseline.pkt * simple1.pkt / simple2.pkt / simple3.pktThe former is completely covered by icmp-before-accept.pkt.The later's delta is the src/dst IP pair to generate a differentcookie, but supporting dualstack requires churn in ksft_runner.sh,so defered to future series. Also, sockopt-fastopen-key.pkt coversthe same function.The following tests have the experimental version only, so convertedto the non-experimental option: * client-ack-dropped-then-recovery-ms-timestamps.pkt * sockopt-fastopen-key.pktFor the imported tests, these common changes are applied. * Add SPDX header * Adjust path to default.sh * Adjust sysctl w/ set_sysctls.py * Use TFO_COOKIE instead of a raw hex value * Use SOCK_NONBLOCK for socket() not to block accept() * Add assertions for TCP state if commented * Remove unnecessary delay (e.g. +0.1 setsockopt(SO_REUSEADDR), etc)With this series, except for simple{1,2,3}.pkt, we can remove TFO servertests in google/packetdrill.====================Link: https://patch.msgid.link/20250927213022.1850048-1-kuniyu@google.comSigned-off-by: Jakub Kicinski List of files: /linux/tools/testing/selftests/net/packetdrill/tcp_fastopen_server_basic-pure-syn-data.pkt

selftest: packetdrill: Import TFO server basic tests.This imports basic TFO server tests from google/packetdrill.The repository has two versions of tests for most scenarios; one usesthe non-experimental option (34), and the other uses the experimentaloption (255) with 0xF989.This only imports the following tests of the non-experimental versionplaced in [0]. I will add a specific test for the experimental optionhandling later. | TFO | Cookie | Payload | ---------------------------+-----+--------+---------+ basic-rw.pkt | yes | yes | yes | basic-zero-payload.pkt | yes | yes | no | basic-cookie-not-reqd.pkt | yes | no | yes | basic-non-tfo-listener.pkt | no | yes | yes | pure-syn-data.pkt | yes | no | yes |The original pure-syn-data.pkt missed setsockopt(TCP_FASTOPEN) and didnot test TFO server in some scenarios unintentionally, so setsockopt()is added where needed. In addition, non-TFO scenario is stripped asit is covered by basic-non-tfo-listener.pkt.
