Merge tag 'net-next-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next
Pull networking changes from Paolo Abeni: "Core: - Refactor the forward memory allocation to better cope with memory pressure with many open sockets, moving from a per socket cache to a per-CPU one - Replace rwlocks with RCU for better fairness in ping, raw sockets and IP multicast router. - Network-side support for IO uring zero-copy send. - A few skb drop reason improvements, including codegen the source file with string mapping instead of using macro magic. - Rename reference tracking helpers to a more consistent netdev_* schema. - Adapt u64_stats_t type to address load/store tearing issues. - Refine debug helper usage to reduce the log noise caused by bots. BPF: - Improve socket map performance, avoiding skb cloning on read operation. - Add support for 64 bits enum, to match types exposed by kernel. - Introduce support for sleepable uprobes program. - Introduce support for enum textual representation in libbpf. - New helpers to implement synproxy with eBPF/XDP. - Improve loop performances, inlining indirect calls when possible. - Removed all the deprecated libbpf APIs. - Implement new eBPF-based LSM flavor. - Add type match support, which allow accurate queries to the eBPF used types. - A few TCP congetsion control framework usability improvements. - Add new infrastructure to manipulate CT entries via eBPF programs. - Allow for livepatch (KLP) and BPF trampolines to attach to the same kernel function. Protocols: - Introduce per network namespace lookup tables for unix sockets, increasing scalability and reducing contention. - Preparation work for Wi-Fi 7 Multi-Link Operation (MLO) support. - Add support to forciby close TIME_WAIT TCP sockets via user-space tools. - Significant performance improvement for the TLS 1.3 receive path, both for zero-copy and not-zero-copy. - Support for changing the initial MTPCP subflow priority/backup status - Introduce virtually contingus buffers for sockets over RDMA, to cope better with memory pressure. - Extend CAN ethtool support with timestamping capabilities - Refactor CAN build infrastructure to allow building only the needed features. Driver API: - Remove devlink mutex to allow parallel commands on multiple links. - Add support for pause stats in distributed switch. - Implement devlink helpers to query and flash line cards. - New helper for phy mode to register conversion. New hardware / drivers: - Ethernet DSA driver for the rockchip mt7531 on BPI-R2 Pro. - Ethernet DSA driver for the Renesas RZ/N1 A5PSW switch. - Ethernet DSA driver for the Microchip LAN937x switch. - Ethernet PHY driver for the Aquantia AQR113C EPHY. - CAN driver for the OBD-II ELM327 interface. - CAN driver for RZ/N1 SJA1000 CAN controller. - Bluetooth: Infineon CYW55572 Wi-Fi plus Bluetooth combo device. Drivers: - Intel Ethernet NICs: - i40e: add support for vlan pruning - i40e: add support for XDP framented packets - ice: improved vlan offload support - ice: add support for PPPoE offload - Mellanox Ethernet (mlx5) - refactor packet steering offload for performance and scalability - extend support for TC offload - refactor devlink code to clean-up the locking schema - support stacked vlans for bridge offloads - use TLS objects pool to improve connection rate - Netronome Ethernet NICs (nfp): - extend support for IPv6 fields mangling offload - add support for vepa mode in HW bridge - better support for virtio data path acceleration (VDPA) - enable TSO by default - Microsoft vNIC driver (mana) - add support for XDP redirect - Others Ethernet drivers: - bonding: add per-port priority support - microchip lan743x: extend phy support - Fungible funeth: support UDP segmentation offload and XDP xmit - Solarflare EF100: add support for virtual function representors - MediaTek SoC: add XDP support - Mellanox Ethernet/IB switch (mlxsw): - dropped support for unreleased H/W (XM router). - improved stats accuracy - unified bridge model coversion improving scalability (parts 1-6) - support for PTP in Spectrum-2 asics - Broadcom PHYs - add PTP support for BCM54210E - add support for the BCM53128 internal PHY - Marvell Ethernet switches (prestera): - implement support for multicast forwarding offload - Embedded Ethernet switches: - refactor OcteonTx MAC filter for better scalability - improve TC H/W offload for the Felix driver - refactor the Microchip ksz8 and ksz9477 drivers to share the probe code (parts 1, 2), add support for phylink mac configuration - Other WiFi: - Microchip wilc1000: diable WEP support and enable WPA3 - Atheros ath10k: encapsulation offload support Old code removal: - Neterion vxge ethernet driver: this is untouched since more than 10 years" * tag 'net-next-6.0' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1890 commits) doc: sfp-phylink: Fix a broken reference wireguard: selftests: support UML wireguard: allowedips: don't corrupt stack when detecting overflow wireguard: selftests: update config fragments wireguard: ratelimiter: use hrtimer in selftest net/mlx5e: xsk: Discard unaligned XSK frames on striding RQ net: usb: ax88179_178a: Bind only to vendor-specific interface selftests: net: fix IOAM test skip return code net: usb: make USB_RTL8153_ECM non user configurable net: marvell: prestera: remove reduntant code octeontx2-pf: Reduce minimum mtu size to 60 net: devlink: Fix missing mutex_unlock() call net/tls: Remove redundant workqueue flush before destroy net: txgbe: Fix an error handling path in txgbe_probe() net: dsa: Fix spelling mistakes and cleanup code Documentation: devlink: add add devlink-selftests to the table of contents dccp: put dccp_qpolicy_full() and dccp_qpolicy_push() in the same lock net: ionic: fix error check for vlan flags in ionic_set_nic_features() net: ice: fix error NETIF_F_HW_VLAN_CTAG_FILTER check in ice_vsi_sync_fltr() nfp: flower: add support for tunnel offload without key ID ...
