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.
