![]() Core ---- - More core refactoring to reduce the RTNL lock contention, including preparatory work for the per-network namespace RTNL lock, replacing RTNL lock with a per device-one to protect NAPI-related net device data and moving synchronize_net() calls outside such lock. - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and more specific TCP coverage. - Reduce network namespace tear-down time by removing per-subsystems synchronize_net() in tipc and sched. - Add flow label selector support for fib rules, allowing traffic redirection based on such header field. Netfilter --------- - Do not remove netdev basechain when last device is gone, allowing netdev basechains without devices. - Revisit the flowtable teardown strategy, dealing better with fin, reset and re-open events. - Scale-up IP-vs connection dumping by avoiding linear search on each restart. Protocols --------- - A significant XDP socket refactor, consolidating and optimizing several helpers into the core - Better scaling of ICMP rate-limiting, by removing false-sharing in inet peers handling. - Introduces netlink notifications for multicast IPv4 and IPv6 address changes. - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing aggregation and fragmentation of the inner IP. - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to avoid local port exhaustion issues when the average connection lifetime is very short. - Support updating keys (re-keying) for connections using kernel TLS (for TLS 1.3 only). - Support ipv4-mapped ipv6 address clients in smc-r v2. - Add support for jumbo data packet transmission in RxRPC sockets, gluing multiple data packets in a single UDP packet. - Support RxRPC RACK-TLP to manage packet loss and retransmission in conjunction with the congestion control algorithm. Driver API ---------- - Introduce a unified and structured interface for reporting PHY statistics, exposing consistent data across different H/W via ethtool. - Make timestamping selectable, allow the user to select the desired hwtstamp provider (PHY or MAC) administratively. - Add support for configuring a header-data-split threshold (HDS) value via ethtool, to deal with partial or buggy H/W implementation. - Consolidate DSA drivers Energy Efficiency Ethernet support. - Add EEE management to phylink, making use of the phylib implementation. - Add phylib support for in-band capabilities negotiation. - Simplify how phylib-enabled mac drivers expose the supported interfaces. Tests and tooling ----------------- - Make the YNL tool package-friendly to make it easier to deploy it separately from the kernel. - Increase TCP selftest coverage importing several packetdrill test-cases. - Regenerate the ethtool uapi header from the YNL spec, to ease maintenance and future development. - Add YNL support for decoding the link types used in net self-tests, allowing a single build to run both net and drivers/net. Drivers ------- - Ethernet high-speed NICs: - nVidia/Mellanox (mlx5): - add cross E-Switch QoS support - add SW Steering support for ConnectX-8 - implement support for HW-Managed Flow Steering, improving the rule deletion/insertion rate - support for multi-host LAG - Intel (ixgbe, ice, igb): - ice: add support for devlink health events - ixgbe: add initial support for E610 chipset variant - igb: add support for AF_XDP zero-copy - Meta: - add support for basic RSS config - allow changing the number of channels - add hardware monitoring support - Broadcom (bnxt): - implement TCP data split and HDS threshold ethtool support, enabling Device Memory TCP. - Marvell Octeon: - implement egress ipsec offload support for the cn10k family - Hisilicon (HIBMC): - implement unicast MAC filtering - Ethernet NICs embedded and virtual: - Convert UDP tunnel drivers to NETDEV_PCPU_STAT_DSTATS, avoiding contented atomic operations for drop counters - Freescale: - quicc: phylink conversion - enetc: support Tx and Rx checksum offload and improve TSO performances - MediaTek: - airoha: introduce support for ETS and HTB Qdisc offload - Microchip: - lan78XX USB: preparation work for phylink conversion - Synopsys (stmmac): - support DWMAC IP on NXP Automotive SoCs S32G2xx/S32G3xx/S32R45 - refactor EEE support to leverage the new driver API - optimize DMA and cache access to increase raw RX performances by 40% - TI: - icssg-prueth: add multicast filtering support for VLAN interface - netkit: - add ability to configure head/tailroom - VXLAN: - accepts packets with user-defined reserved bit - Ethernet switches: - Microchip: - lan969x: add RGMII support - lan969x: improve TX and RX performance using the FDMA engine - nVidia/Mellanox: - move Tx header handling to PCI driver, to ease XDP support - Ethernet PHYs: - Texas Instruments DP83822: - add support for GPIO2 clock output - Realtek: - 8169: add support for RTL8125D rev.b - rtl822x: add hwmon support for the temperature sensor - Microchip: - add support for RDS PTP hardware - consolidate periodic output signal generation - CAN: - several DT-bindings to DT schema conversions - tcan4x5x: - add HW standby support - support nWKRQ voltage selection - kvaser: - allowing Bus Error Reporting runtime configuration - WiFi: - the on-going Multi-Link Operation (MLO) effort continues, affecting both the stack and in drivers - mac80211/cfg80211: - Emergency Preparedness Communication Services (EPCS) station mode support - support for adding and removing station links for MLO - add support for WiFi 7/EHT mesh over 320 MHz channels - report Tx power info for each link - RealTek (rtw88): - enable USB Rx aggregation and USB 3 to improve performance - LED support - RealTek (rtw89): - refactor power save to support Multi-Link Operations - add support for RTL8922AE-VS variant - MediaTek (mt76): - single wiphy multiband support (preparation for MLO) - p2p device support - add TP-Link TXE50UH USB adapter support - Qualcomm (ath10k): - support for the QCA6698AQ IP core - Qualcomm (ath12k): - enable MLO for QCN9274 - Bluetooth: - Allow sysfs to trigger hdev reset, to allow recovering devices not responsive from user-space - MediaTek: add support for MT7922, MT7925, MT7921e devices - Realtek: add support for RTL8851BE devices - Qualcomm: add support for WCN785x devices - ISO: allow BIG re-sync Signed-off-by: Paolo Abeni <pabeni@redhat.com> -----BEGIN PGP SIGNATURE----- iQJGBAABCAAwFiEEg1AjqC77wbdLX2LbKSR5jcyPE6QFAmePf5YSHHBhYmVuaUBy ZWRoYXQuY29tAAoJECkkeY3MjxOkUcMQALblhkGTxurnfT+yK+Bsuhn2LoHl2RPN 4u2Kjkzm+2FYgcw6lS17cFXsnfAPlRIpmhnmKk1EBgsBdkuL29c+jtqnljA2bboD tIMhMgWiaLS3xgEMrLeKnseIo0G9mviQRphGeZPFTaLb4Ww/bd5LAp4ZGc5oij76 tURatC3b6MuO4Lt5U+jWKnRwviXku8udHkVHXlvPdirawHCVinmx3tvce/BI/MaD eUOp6ZeJCPCOLtk7b8WEyxxvdY0f6D9ed82qfPDHjb94SJv+Vxb38RZtNuApIjn9 S0KdlNih/4flDy17LDxGYSyFps78lUFRbpqmsUlnZkyLXpsph7/WTvAmMAFcrX0K UgQ/F/q5GAvcP5WZcCj5+tZaRmfKQraQirXMtYU/Uj50qCnSU7ssyACASt23GLZ8 OF8tCLlm9lLOU1B6Ofkul1Dbo5f0Xpaghga4dFb0kzSfbm78fTUnqBNsJ7jIkWfi fD6dO+fg+p2ZMD0CACGo3CNxQuJmaQWg6BIDeno6God8kZ6qBMxY/sFr4qozrvFH x/FgQq8dgc8WLmaPejKiNIPkdQepXrIiv3T9jgMVyEjJnWB/LBfyWKSQOdTfnLs+ rgr4YMV6XW4bx0fYqTI8B9jZ+FCWbG6sn4UtRTHITKcd3FSvd8Y+PHa5YyCUWvJM l8pePMGF0XVF =hrsp -----END PGP SIGNATURE----- Merge tag 'net-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next Pull networking updates from Paolo Abeni: "This is slightly smaller than usual, with the most interesting work being still around RTNL scope reduction.
