Merge tag 'net-next-6.11' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextHEADmaster
Pull networking updates from Jakub Kicinski: "Not much excitement - a handful of large patchsets (devmem among them) did not make it in time. Core & protocols: - Use local_lock in addition to local_bh_disable() to protect per-CPU resources in networking, a step closer for local_bh_disable() not to act as a big lock on PREEMPT_RT - Use flex array for netdevice priv area, ensure its cache alignment - Add a sysctl knob to allow user to specify a default rto_min at socket init time. Bit of a big hammer but multiple companies were independently carrying such patch downstream so clearly it's useful - Support scheduling transmission of packets based on CLOCK_TAI - Un-pin TCP TIMEWAIT timer to avoid it firing on CPUs later cordoned off using cpusets - Support multiple L2TPv3 UDP tunnels using the same 5-tuple address - Allow configuration of multipath hash seed, to both allow synchronizing hashing of two routers, and preventing partial accidental sync - Improve TCP compliance with RFC 9293 for simultaneous connect() - Support sending NAT keepalives in IPsec ESP in UDP states. Userspace IKE daemon had to do this before, but the kernel can better keep track of it - Support sending supervision HSR frames with MAC addresses stored in ProxyNodeTable when RedBox (i.e. HSR-SAN) is enabled - Introduce IPPROTO_SMC for selecting SMC when socket is created - Allow UDP GSO transmit from devices with no checksum offload - openvswitch: add packet sampling via psample, separating the sampled traffic from "upcall" packets sent to user space for forwarding - nf_tables: shrink memory consumption for transaction objects Things we sprinkled into general kernel code: - Power Sequencing subsystem (used by Qualcomm Bluetooth driver for QCA6390) [ Already merged separately - Linus ] - Add IRQ information in sysfs for auxiliary bus - Introduce guard definition for local_lock - Add aligned flavor of __cacheline_group_{begin, end}() markings for grouping fields in structures BPF: - Notify user space (via epoll) when a struct_ops object is getting detached/unregistered - Add new kfuncs for a generic, open-coded bits iterator - Enable BPF programs to declare arrays of kptr, bpf_rb_root, and bpf_list_head - Support resilient split BTF which cuts down on duplication and makes BTF as compact as possible WRT BTF from modules - Add support for dumping kfunc prototypes from BTF which enables both detecting as well as dumping compilable prototypes for kfuncs - riscv64 BPF JIT improvements in particular to add 12-argument support for BPF trampolines and to utilize bpf_prog_pack for the latter - Add the capability to offload the netfilter flowtable in XDP layer through kfuncs Driver API: - Allow users to configure IRQ tresholds between which automatic IRQ moderation can choose - Expand Power Sourcing (PoE) status with power, class and failure reason. Support setting power limits - Track additional RSS contexts in the core, make sure configuration changes don't break them - Support IPsec crypto offload for IPv6 ESP and IPv4 UDP-encapsulated ESP data paths - Support updating firmware on SFP modules Tests and tooling: - mptcp: use net/lib.sh to manage netns - TCP-AO and TCP-MD5: replace debug prints used by tests with tracepoints - openvswitch: make test self-contained (don't depend on OvS CLI tools) Drivers: -

- * struct iwl_trans_ops - transport specific operations
- *
- * All the handlers MUST be implemented
- *
- * @start_hw: starts the HW. From that point on, the HW can send interrupts.
- * May sleep.
- * @op_mode_leave: Turn off the HW RF kill indication if on
- * May sleep
- * @start_fw: allocates and inits all the resources for the transport
- * layer. Also kick a fw image.
- * May sleep
- * @fw_alive: called when the fw sends alive notification. If the fw provides
- * the SCD base address in SRAM, then provide it here, or 0 otherwise.
- * May sleep
- * @stop_device: stops the whole device (embedded CPU put to reset) and stops
- * the HW. From that point on, the HW will be stopped but will still issue
- * an interrupt if the HW RF kill switch is triggered.
- * This callback must do the right thing and not crash even if %start_hw()
- * was called but not &start_fw(). May sleep.
- * @d3_suspend: put the device into the correct mode for WoWLAN during
- * suspend. This is optional, if not implemented WoWLAN will not be
- * supported. This callback may sleep.
- * @d3_resume: resume the device after WoWLAN, enabling the opmode to
- * talk to the WoWLAN image to get its status. This is optional, if not
- * implemented WoWLAN will not be supported. This callback may sleep.
- * @send_cmd:send a host command. Must return -ERFKILL if RFkill is asserted.
- * If RFkill is asserted in the middle of a SYNC host command, it must
- * return -ERFKILL straight away.
- * May sleep only if CMD_ASYNC is not set
- * @tx: send an skb. The transport relies on the op_mode to zero the
- * the ieee80211_tx_info->driver_data. If the MPDU is an A-MSDU, all
- * the CSUM will be taken care of (TCP CSUM and IP header in case of
- * IPv4). If the MPDU is a single MSDU, the op_mode must compute the IP
- * header if it is IPv4.
- * Must be atomic
- * @reclaim: free packet until ssn. Returns a list of freed packets.
- * Must be atomic
- * @set_q_ptrs: set queue pointers internally, after D3 when HW state changed
- * @txq_enable: setup a queue. To setup an AC queue, use the
- * iwl_trans_ac_txq_enable wrapper. fw_alive must have been called before
- * this one. The op_mode must not configure the HCMD queue. The scheduler
- * configuration may be %NULL, in which case the hardware will not be
- * configured. If true is returned, the operation mode needs to increment
- * the sequence number of the packets routed to this queue because of a
- * hardware scheduler bug. May sleep.
- * @txq_disable: de-configure a Tx queue to send AMPDUs
- * Must be atomic
- * @txq_alloc: Allocate a new TX queue, may sleep.
- * @txq_free: Free a previously allocated TX queue.
- * @txq_set_shared_mode: change Tx queue shared/unshared marking
- * @wait_tx_queues_empty: wait until tx queues are empty. May sleep.
- * @wait_txq_empty: wait until specific tx queue is empty. May sleep.
- * @freeze_txq_timer: prevents the timer of the queue from firing until the
- * queue is set to awake. Must be atomic.
- * @write8: write a u8 to a register at offset ofs from the BAR
- * @write32: write a u32 to a register at offset ofs from the BAR
- * @read32: read a u32 register at offset ofs from the BAR
- * @read_prph: read a DWORD from a periphery register
- * @write_prph: write a DWORD to a periphery register
- * @read_mem: read device's SRAM in DWORD
- * @write_mem: write device's SRAM in DWORD. If %buf is %NULL, then the memory
- * will be zeroed.
- * @read_config32: read a u32 value from the device's config space at
- * the given offset.
- * @configure: configure parameters required by the transport layer from
- * the op_mode. May be called several times before start_fw, can't be
- * called after that.
- * @set_pmi: set the power pmi state
- * @sw_reset: trigger software reset of the NIC
- * @grab_nic_access: wake the NIC to be able to access non-HBUS regs.
- * Sleeping is not allowed between grab_nic_access and
- * release_nic_access.
- * @release_nic_access: let the NIC go to sleep. The "flags" parameter
- * must be the same one that was sent before to the grab_nic_access.
- * @set_bits_mask: set SRAM register according to value and mask.
- * @dump_data: return a vmalloc'ed buffer with debug data, maybe containing last
- * TX'ed commands and similar. The buffer will be vfree'd by the caller.
- * Note that the transport must fill in the proper file headers.
- * @debugfs_cleanup: used in the driver unload flow to make a proper cleanup
- * of the trans debugfs
- * @sync_nmi: trigger a firmware NMI and wait for it to complete
- * @load_pnvm: save the pnvm data in DRAM
- * @set_pnvm: set the pnvm data in the prph scratch buffer, inside the
- * context info.
- * @load_reduce_power: copy reduce power table to the corresponding DRAM memory
- * @set_reduce_power: set reduce power table addresses in the sratch buffer
- * @interrupts: disable/enable interrupts to transport
- * @imr_dma_data: set up IMR DMA
- * @rxq_dma_data: retrieve RX queue DMA data, see @struct iwl_trans_rxq_dma_data
