Increase single TCP flow performance on a 200Gbit NIC by 20% (100Gbit -> 120Gbit). - The Fair Queuing (FQ) packet scheduler: - add built-in 3 band prio / WRR scheduling - support bypass if the qdisc is mostly idle (5% speed up for TCP RR) - improve inactive flow reporting - optimize the layout of structures for better cache locality - Support TCP Authentication Option (RFC 5925, TCP-AO), a more modern replacement for the old MD5 option. - Add more retransmission timeout (RTO) related statistics to TCP_INFO. - Support sending fragmented skbs over vsock sockets. - Make sure we send SIGPIPE for vsock sockets if socket was shutdown(). - Add sysctl for ignoring lower limit on lifetime in Router Advertisement PIO, based on an in-progress IETF draft. - Add sysctl to control activation of TCP ping-pong mode. - Add sysctl to make connection timeout in MPTCP configurable. - Support rcvlowat and notsent_lowat on MPTCP sockets, to help apps limit the number of wakeups. - Support netlink GET for MDB (multicast forwarding), allowing user space to request a single MDB entry instead of dumping the entire table. - Support selective FDB flushing in the VXLAN tunnel driver. - Allow limiting learned FDB entries in bridges, prevent OOM attacks. - Allow controlling via configfs netconsole targets which were created via the kernel cmdline at boot, rather than via configfs at runtime. - Support multiple PTP timestamp event queue readers with different filters. - MCTP over I3C. BPF: - Add new veth-like netdevice where BPF program defines the logic of the xmit routine. It can operate in L3 and L2 mode. - Support exceptions - allow asserting conditions which should never be true but are hard for the verifier to infer. With some extra flexibility around handling of the exit / failure: https://lwn.net/Articles/938435/ - Add support for local per-cpu kptr, allow allocating and storing per-cpu objects in maps. Access to those objects operates on the value for the current CPU. This allows to deprecate local one-off implementations of per-CPU storage like BPF_MAP_TYPE_PERCPU_CGROUP_STORAGE maps. - Extend cgroup BPF sockaddr hooks for UNIX sockets. The use case is for systemd to re-implement the LogNamespace feature which allows running multiple instances of systemd-journald to process the logs of different services. - Enable open-coded task_vma iteration, after maple tree conversion made it hard to directly walk VMAs in tracing programs. - Add open-coded task, css_task and css iterator support. One of the use cases is customizable OOM victim selection via BPF. - Allow source address selection with bpf_*_fib_lookup(). - Add ability to pin BPF timer to the current CPU. - Prevent creation of infinite loops by combining tail calls and fentry/fexit programs. - Add missed stats for kprobes to retrieve the number of missed kprobe executions and subsequent executions of BPF programs. - Inherit system settings for CPU security mitigations. - Add BPF v4 CPU instruction support for arm32 and s390x. Changes to common code: - overflow: add DEFINE_FLEX() for on-stack definition of structs with flexible array members. - Process doc update with more guidance for reviewers. Driver API: - Simplify locking in WiFi (cfg80211 and mac80211 layers), use wiphy mutex in most places and remove a lot of smaller locks. - Create a common DPLL configuration API. Allow configuring and querying state of PLL circuits used for clock syntonization, in network time distribution. - Unify fragmented and full page allocation APIs in page pool code. Let drivers be ignorant of PAGE_SIZE. - Rework PHY state machine to avoid races with calls to phy_stop(). - Notify DSA drivers of MAC address changes on user ports, improve correctness of offloads which depend on matching port MAC addresses. - Allow antenna control on injected WiFi frames. - Reduce the number of variants of napi_schedule(). - Simplify error handling when composing devlink health messages. Misc: - A lot of KCSAN data race "fixes", from Eric. - A lot of __counted_by() annotations, from Kees. - A lot of strncpy -> strscpy and printf format fixes. - Replace master/slave terminology with conduit/user in DSA drivers. - Handful of KUnit tests for netdev and WiFi core. Removed: - AppleTalk COPS. - AppleTalk ipddp. - TI AR7 CPMAC Ethernet driver. Drivers: - Ethernet high-speed NICs: - Intel (100G, ice, idpf): - add a driver for the Intel E2000 IPUs - make CRC/FCS stripping configurable - cross-timestamping for E823 devices - basic support for E830 devices - use aux-bus for managing client drivers - i40e: report firmware versions via devlink - nVidia/Mellanox: - support 4-port NICs - increase max number of channels to 256 - optimize / parallelize SF creation flow - Broadcom (bnxt): - enhance NIC temperature reporting - support PAM4 speeds and lane configuration - Marvell OcteonTX2: - PTP pulse-per-second output support - enable hardware timestamping for VFs - Solarflare/AMD: - conntrack NAT offload and offload for tunnels - Wangxun (ngbe/txgbe): - expose HW statistics - Pensando/AMD: - support PCI level reset - narrow down the condition under which skbs are linearized - Netronome/Corigine (nfp): - support CHACHA20-POLY1305 crypto in IPsec offload - Ethernet NICs embedded, slower, virtual: - Synopsys (stmmac): - add Loongson-1 SoC support - enable use of HW queues with no offload capabilities - enable PPS input support on all 5 channels - increase TX coalesce timer to 5ms - RealTek USB (r8152): improve efficiency of Rx by using GRO frags - xen: support SW packet timestamping - add drivers for implementations based on TI's PRUSS (AM64x EVM) - nVidia/Mellanox Ethernet datacenter switches: - avoid poor HW resource use on Spectrum-4 by better block selection for IPv6 multicast forwarding and ordering of blocks in ACL region - Ethernet embedded switches: - Microchip: - support configuring the drive strength for EMI compliance - ksz9477: partial ACL support - ksz9477: HSR offload - ksz9477: Wake on LAN - Realtek: - rtl8366rb: respect device tree config of the CPU port - Ethernet PHYs: - support Broadcom BCM5221 PHYs - TI dp83867: support hardware LED blinking - CAN: - add support for Linux-PHY based CAN transceivers - at91_can: clean up and use rx-offload helpers - WiFi: - MediaTek (mt76): - new sub-driver for mt7925 USB/PCIe devices - HW wireless <> Ethernet bridging in MT7988 chips - mt7603/mt7628 stability improvements - Qualcomm (ath12k): - WCN7850: - enable 320 MHz channels in 6 GHz band - hardware rfkill support - enable IEEE80211_HW_SINGLE_SCAN_ON_ALL_BANDS to make scan faster - read board data variant name from SMBIOS - QCN9274: mesh support - RealTek (rtw89): - TDMA-based multi-channel concurrency (MCC) - Silicon Labs (wfx): - Remain-On-Channel (ROC) support - Bluetooth: - ISO: many improvements for broadcast support - mark BCM4378/BCM4387 as BROKEN_LE_CODED - add support for QCA2066 - btmtksdio: enable Bluetooth wakeup from suspend" * tag 'net-next-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1816 commits) net: pcs: xpcs: Add 2500BASE-X case in get state for XPCS drivers net: bpf: Use sockopt_lock_sock() in ip_sock_set_tos() net: mana: Use xdp_set_features_flag instead of direct assignment vxlan: Cleanup IFLA_VXLAN_PORT_RANGE entry in vxlan_get_size() iavf: delete the iavf client interface iavf: add a common function for undoing the interrupt scheme iavf: use unregister_netdev iavf: rely on netdev's own registered state iavf: fix the waiting time for initial reset iavf: in iavf_down, don't queue watchdog_task if comms failed iavf: simplify mutex_trylock+sleep loops iavf: fix comments about old bit locks doc/netlink: Update schema to support cmd-cnt-name and cmd-max-name tools: ynl: introduce option to process unknown attributes or types ipvlan: properly track tx_errors netdevsim: Block until all devices are released nfp: using napi_build_skb() to replace build_skb() net: dsa: microchip: ksz9477: Fix spelling mistake "Enery" -> "Energy" net: dsa: microchip: Ensure Stable PME Pin State for Wake-on-LAN net: dsa: microchip: Refactor switch shutdown routine for WoL preparation ...

| * netlink: specs: support conditional operationsJakub Kicinski2023-10-263-0/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Page pool code is compiled conditionally, but the operations are part of the shared netlink family. We can handle this by reporting empty list of pools or -EOPNOTSUPP / -ENOSYS but the cleanest way seems to be removing the ops completely at compilation time. That way user can see that the page pool ops are not present using genetlink introspection. Same way they'd check if the kernel is "new enough" to support the ops. Extend the specs with the ability to specify the config condition under which op (and its policies, etc.) should be hidden.

The support is less than trivial, because we try to keep struct nla_policy tiny the min/max members it holds in place are s16. Meaning we can only express checks in range of s16. For larger ranges we need to define a structure and link it in the policy. Link: https://lore.kernel.org/r/20231018163917.2514503-3-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>

The scheduler can now find an svc thread to wake in constant time and without a list walk. Thanks again to Neil Brown for this overhaul. Lorenzo Bianconi contributed infrastructure for a netlink-based NFSD control plane. The long-term plan is to provide the same functionality as found in /proc/fs/nfsd, plus some interesting additions, and then migrate the NFSD user space utilities to netlink. A long series to overhaul NFSD's NFSv4 operation encoding was applied in this release. The goals are to bring this family of encoding functions in line with the matching NFSv4 decoding functions and with the NFSv2 and NFSv3 XDR functions, preparing the way for better memory safety and maintainability. A further improvement to NFSD's write delegation support was contributed by Dai Ngo. This adds a CB_GETATTR callback, enabling the server to retrieve cached size and mtime data from clients holding write delegations. If the server can retrieve this information, it does not have to recall the delegation in some cases. The usual panoply of bug fixes and minor improvements round out this release. As always I am grateful to all contributors, reviewers, and testers" * tag 'nfsd-6.7' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux: (127 commits) svcrdma: Fix tracepoint printk format svcrdma: Drop connection after an RDMA Read error NFSD: clean up alloc_init_deleg() NFSD: Fix frame size warning in svc_export_parse() NFSD: Rewrite synopsis of nfsd_percpu_counters_init() nfsd: Clean up errors in nfs3proc.c nfsd: Clean up errors in nfs4state.c NFSD: Clean up errors in stats.c NFSD: simplify error paths in nfsd_svc() NFSD: Clean up nfsd4_encode_seek() NFSD: Clean up nfsd4_encode_offset_status() NFSD: Clean up nfsd4_encode_copy_notify() NFSD: Clean up nfsd4_encode_copy() NFSD: Clean up nfsd4_encode_test_stateid() NFSD: Clean up nfsd4_encode_exchange_id() NFSD: Clean up nfsd4_do_encode_secinfo() NFSD: Clean up nfsd4_encode_access() NFSD: Clean up nfsd4_encode_readdir() NFSD: Clean up nfsd4_encode_entry4() NFSD: Add an nfsd4_encode_nfs_cookie4() helper ...
