Core ---- - Increase size limits for to-be-sent skb frag allocations. This allows tun, tap devices and packet sockets to better cope with large writes operations. - Store netdevs in an xarray, to simplify iterating over netdevs. - Refactor nexthop selection for multipath routes. - Improve sched class lifetime handling. - Add backup nexthop ID support for bridge. - Implement drop reasons support in openvswitch. - Several data races annotations and fixes. - Constify the sk parameter of routing functions. - Prepend kernel version to netconsole message. Protocols --------- - Implement support for TCP probing the peer being under memory pressure. - Remove hard coded limitation on IPv6 specific info placement inside the socket struct. - Get rid of sysctl_tcp_adv_win_scale and use an auto-estimated per socket scaling factor. - Scaling-up the IPv6 expired route GC via a separated list of expiring routes. - In-kernel support for the TLS alert protocol. - Better support for UDP reuseport with connected sockets. - Add NEXT-C-SID support for SRv6 End.X behavior, reducing the SR header size. - Get rid of additional ancillary per MPTCP connection struct socket. - Implement support for BPF-based MPTCP packet schedulers. - Format MPTCP subtests selftests results in TAP. - Several new SMC 2.1 features including unique experimental options, max connections per lgr negotiation, max links per lgr negotiation. BPF --- - Multi-buffer support in AF_XDP. - Add multi uprobe BPF links for attaching multiple uprobes and usdt probes, which is significantly faster and saves extra fds. - Implement an fd-based tc BPF attach API (TCX) and BPF link support on top of it. - Add SO_REUSEPORT support for TC bpf_sk_assign. - Support new instructions from cpu v4 to simplify the generated code and feature completeness, for x86, arm64, riscv64. - Support defragmenting IPv(4|6) packets in BPF. - Teach verifier actual bounds of bpf_get_smp_processor_id() and fix perf+libbpf issue related to custom section handling. - Introduce bpf map element count and enable it for all program types. - Add a BPF hook in sys_socket() to change the protocol ID from IPPROTO_TCP to IPPROTO_MPTCP to cover migration for legacy. - Introduce bpf_me_mcache_free_rcu() and fix OOM under stress. - Add uprobe support for the bpf_get_func_ip helper. - Check skb ownership against full socket. - Support for up to 12 arguments in BPF trampoline. - Extend link_info for kprobe_multi and perf_event links. Netfilter --------- - Speed-up process exit by aborting ruleset validation if a fatal signal is pending. - Allow NLA_POLICY_MASK to be used with BE16/BE32 types. Driver API ---------- - Page pool optimizations, to improve data locality and cache usage. - Introduce ndo_hwtstamp_get() and ndo_hwtstamp_set() to avoid the need for raw ioctl() handling in drivers. - Simplify genetlink dump operations (doit/dumpit) providing them the common information already populated in struct genl_info. - Extend and use the yaml devlink specs to [re]generate the split ops. - Introduce devlink selective dumps, to allow SF filtering SF based on handle and other attributes. - Add yaml netlink spec for netlink-raw families, allow route, link and address related queries via the ynl tool. - Remove phylink legacy mode support. - Support offload LED blinking to phy. - Add devlink port function attributes for IPsec.
