Merge tag 'net-next-6.3' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-nextgrafted
Pull networking updates from Jakub Kicinski: "Core: - Add dedicated kmem_cache for typical/small skb->head, avoid having to access struct page at kfree time, and improve memory use. - Introduce sysctl to set default RPS configuration for new netdevs. - Define Netlink protocol specification format which can be used to describe messages used by each family and auto-generate parsers. Add tools for generating kernel data structures and uAPI headers. - Expose all net/core sysctls inside netns. - Remove 4s sleep in netpoll if carrier is instantly detected on boot. - Add configurable limit of MDB entries per port, and port-vlan. - Continue populating drop reasons throughout the stack. - Retire a handful of legacy Qdiscs and classifiers. Protocols: - Support IPv4 big TCP (TSO frames larger than 64kB). - Add IP_LOCAL_PORT_RANGE socket option, to control local port range on socket by socket basis. - Track and report in procfs number of MPTCP sockets used. - Support mixing IPv4 and IPv6 flows in the in-kernel MPTCP path manager. - IPv6: don't check net.ipv6.route.max_size and rely on garbage collection to free memory (similarly to IPv4). - Support Penultimate Segment Pop (PSP) flavor in SRv6 (RFC8986). - ICMP: add per-rate limit counters. - Add support for user scanning requests in ieee802154. - Remove static WEP support. - Support minimal Wi-Fi 7 Extremely High Throughput (EHT) rate reporting. - WiFi 7 EHT channel puncturing support (client & AP). BPF: - Add a rbtree data structure following the "next-gen data structure" precedent set by recently added linked list, that is, by using kfunc + kptr instead of adding a new BPF map type. - Expose XDP hints via kfuncs with initial support for RX hash and timestamp metadata. - Add BPF_F_NO_TUNNEL_KEY extension to bpf_skb_set_tunnel_key to better support decap on GRE tunnel devices not operating in collect metadata. - Improve x86 JIT's codegen for PROBE_MEM runtime error checks. - Remove the need for trace_printk_lock for bpf_trace_printk and bpf_trace_vprintk helpers. - Extend libbpf's bpf_tracing.h support for tracing arguments of kprobes/uprobes and syscall as a special case. - Significantly reduce the search time for module symbols by livepatch and BPF. - Enable cpumasks to be used as kptrs, which is useful for tracing programs tracking which tasks end up running on which CPUs in different time intervals. - Add support for BPF trampoline on s390x and riscv64. - Add capability to export the XDP features supported by the NIC. - Add __bpf_kfunc tag for marking kernel functions as kfuncs. - Add cgroup.memory=nobpf kernel parameter option to disable BPF memory accounting for container environments. Netfilter: - Remove the CLUSTERIP target. It has been marked as obsolete for years, and we still have WARN splats wrt races of the out-of-band /proc interface installed by this target. - Add 'destroy' commands to nf_tables. They are identical to the existing 'delete' commands, but do not return an error if the referenced object (set, chain, rule...) did not exist. Driver API: - Improve cpumask_local_spread() locality to help NICs set the right IRQ affinity on AMD platforms. - Separate C22 and C45 MDIO bus transactions more clearly. - Introduce new DCB table to control DSCP rewrite on egress. - Support configuration of Physical Layer Collision Avoidance (PLCA) Reconciliation Sublayer (RS) (802.3cg-2019). Modern version of shared medium Ethernet. - Support for MAC Merge layer (IEEE 802.3-2018 clause 99). Allowing preemption of low priority frames by high priority frames. - Add support for controlling MACSec offload using netlink SET. - Rework devlink instance refcounts to allow registration and de-registration under the instance lock. Split the code into multiple files, drop some of the unnecessarily granular locks and factor out common parts of netlink operation handling. - Add TX frame aggregation parameters (for USB drivers). - Add a new attr TCA_EXT_WARN_MSG to report TC (offload) warning messages with notifications for debug. - Allow offloading of UDP NEW connections via act_ct. - Add support for per action HW stats in TC. - Support hardware miss to TC action (continue processing in SW from a specific point in the action chain). - Warn if old Wireless Extension user space interface is used with modern cfg80211/mac80211 drivers. Do not support Wireless Extensions for Wi-Fi 7 devices at all. Everyone should switch to using nl80211 interface instead. - Improve the CAN bit timing configuration. Use extack to return error messages directly to user space, update the SJW handling, including the definition of a new default value that will benefit CAN-FD controllers, by increasing their oscillator tolerance.

+
+``int ioctl(int fd, CEC_ADAP_S_LOG_ADDRS, struct cec_log_addrs *argp)``
+
+Arguments
+=========
+
+``fd``
+ File descriptor returned by :c:func:`open()`.
+
+``argp``
+ Pointer to struct :c:type:`cec_log_addrs`.
+
+Description
+===========
+
+To query the current CEC logical addresses, applications call
+:ref:`ioctl CEC_ADAP_G_LOG_ADDRS <CEC_ADAP_G_LOG_ADDRS>` with a pointer to a
+struct :c:type:`cec_log_addrs` where the driver stores the logical addresses.
+
+To set new logical addresses, applications fill in
+struct :c:type:`cec_log_addrs` and call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+with a pointer to this struct. The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+is only available if ``CEC_CAP_LOG_ADDRS`` is set (the ``ENOTTY`` error code is
+returned otherwise). The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>`
+can only be called by a file descriptor in initiator mode (see :ref:`CEC_S_MODE`), if not
+the ``EBUSY`` error code will be returned.
+
+To clear existing logical addresses set ``num_log_addrs`` to 0. All other fields
+will be ignored in that case. The adapter will go to the unconfigured state and the
+``cec_version``, ``vendor_id`` and ``osd_name`` fields are all reset to their default
+values (CEC version 2.0, no vendor ID and an empty OSD name).
+
+If the physical address is valid (see :ref:`ioctl CEC_ADAP_S_PHYS_ADDR <CEC_ADAP_S_PHYS_ADDR>`),
+then this ioctl will block until all requested logical
+addresses have been claimed. If the file descriptor is in non-blocking mode then it will
+not wait for the logical addresses to be claimed, instead it just returns 0.
+
+A :ref:`CEC_EVENT_STATE_CHANGE <CEC-EVENT-STATE-CHANGE>` event is sent when the
+logical addresses are claimed or cleared.
+
+Attempting to call :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>` when
+logical address types are already defined will return with error ``EBUSY``.

+
+ * - __u8
+ - ``log_addr[CEC_MAX_LOG_ADDRS]``
+ - The actual logical addresses that were claimed. This is set by the
+ driver. If no logical address could be claimed, then it is set to
+ ``CEC_LOG_ADDR_INVALID``. If this adapter is Unregistered, then
+ ``log_addr[0]`` is set to 0xf and all others to
+ ``CEC_LOG_ADDR_INVALID``.
+ * - __u16
+ - ``log_addr_mask``
+ - The bitmask of all logical addresses this adapter has claimed. If
+ this adapter is Unregistered then ``log_addr_mask`` sets bit 15
+ and clears all other bits. If this adapter is not configured at
+ all, then ``log_addr_mask`` is set to 0. Set by the driver.
+ * - __u8
+ - ``cec_version``
+ - The CEC version that this adapter shall use. See
+ :ref:`cec-versions`. Used to implement the
+ ``CEC_MSG_CEC_VERSION`` and ``CEC_MSG_REPORT_FEATURES`` messages.
+ Note that :ref:`CEC_OP_CEC_VERSION_1_3A <CEC-OP-CEC-VERSION-1-3A>` is not allowed by the CEC
+ framework.
+ * - __u8
+ - ``num_log_addrs``
+ - Number of logical addresses to set up. Must be ≤
+ ``available_log_addrs`` as returned by
+ :ref:`CEC_ADAP_G_CAPS`. All arrays in
+ this structure are only filled up to index
+ ``available_log_addrs``-1. The remaining array elements will be
+ ignored. Note that the CEC 2.0 standard allows for a maximum of 2
+ logical addresses, although some hardware has support for more.
+ ``CEC_MAX_LOG_ADDRS`` is 4. The driver will return the actual
+ number of logical addresses it could claim, which may be less than
+ what was requested. If this field is set to 0, then the CEC
+ adapter shall clear all claimed logical addresses and all other
+ fields will be ignored.
+ * - __u32
+ - ``vendor_id``
+ - The vendor ID is a 24-bit number that identifies the specific
+ vendor or entity. Based on this ID vendor specific commands may be
+ defined. If you do not want a vendor ID then set it to
+ ``CEC_VENDOR_ID_NONE``.
+ * - __u32
+ - ``flags``
+ - Flags. See :ref:`cec-log-addrs-flags` for a list of available flags.
+ * - char
+ - ``osd_name[15]``
+ - The On-Screen Display name as is returned by the
+ ``CEC_MSG_SET_OSD_NAME`` message.
+ * - __u8
+ - ``primary_device_type[CEC_MAX_LOG_ADDRS]``
+ - Primary device type for each logical address. See
+ :ref:`cec-prim-dev-types` for possible types.
+ * - __u8
+ - ``log_addr_type[CEC_MAX_LOG_ADDRS]``
+ - Logical address types. See :ref:`cec-log-addr-types` for
+ possible types. The driver will update this with the actual
+ logical address type that it claimed (e.g. it may have to fallback
+ to :ref:`CEC_LOG_ADDR_TYPE_UNREGISTERED <CEC-LOG-ADDR-TYPE-UNREGISTERED>`).
+ * - __u8
+ - ``all_device_types[CEC_MAX_LOG_ADDRS]``
+ - CEC 2.0 specific: the bit mask of all device types. See
+ :ref:`cec-all-dev-types-flags`. It is used in the CEC 2.0
+ ``CEC_MSG_REPORT_FEATURES`` message. For CEC 1.4 you can either leave
+ this field to 0, or fill it in according to the CEC 2.0 guidelines to
+ give the CEC framework more information about the device type, even
+ though the framework won't use it directly in the CEC message.
+ * - __u8
+ - ``features[CEC_MAX_LOG_ADDRS][12]``
+ - Features for each logical address. It is used in the CEC 2.0
+ ``CEC_MSG_REPORT_FEATURES`` message. The 12 bytes include both the
+ RC Profile and the Device Features. For CEC 1.4 you can either leave
+ this field to all 0, or fill it in according to the CEC 2.0 guidelines to
+ give the CEC framework more information about the device type, even
+ though the framework won't use it directly in the CEC message.

+
+ * .. _`CEC-LOG-ADDRS-FL-ALLOW-UNREG-FALLBACK`:
+
+ - ``CEC_LOG_ADDRS_FL_ALLOW_UNREG_FALLBACK``
+ - 1
+ - By default if no logical address of the requested type can be claimed, then
+ it will go back to the unconfigured state. If this flag is set, then it will
+ fallback to the Unregistered logical address. Note that if the Unregistered
+ logical address was explicitly requested, then this flag has no effect.

+
+ - ``CEC_LOG_ADDRS_FL_ALLOW_RC_PASSTHRU``
+ - 2
+ - By default the ``CEC_MSG_USER_CONTROL_PRESSED`` and ``CEC_MSG_USER_CONTROL_RELEASED``
+ messages are only passed on to the follower(s), if any. If this flag is set,
+ then these messages are also passed on to the remote control input subsystem
+ and will appear as keystrokes. This features needs to be enabled explicitly.
+ If CEC is used to enter e.g. passwords, then you may not want to enable this
+ to avoid trivial snooping of the keystrokes.
+ * .. _`CEC-LOG-ADDRS-FL-CDC-ONLY`:
+
+ - ``CEC_LOG_ADDRS_FL_CDC_ONLY``

+Return Value
+============
+
+On success 0 is returned, on error -1 and the ``errno`` variable is set
+appropriately. The generic error codes are described at the
+:ref:`Generic Error Codes <gen-errors>` chapter.
+
+The :ref:`ioctl CEC_ADAP_S_LOG_ADDRS <CEC_ADAP_S_LOG_ADDRS>` can return the following
+error codes:
+
+ENOTTY
+ The ``CEC_CAP_LOG_ADDRS`` capability wasn't set, so this ioctl is not supported.
+
+EBUSY
+ The CEC adapter is currently configuring itself, or it is already configured and
+ ``num_log_addrs`` is non-zero, or another filehandle is in exclusive follower or
+ initiator mode, or the filehandle is in mode ``CEC_MODE_NO_INITIATOR``.
+
+EINVAL
+ The contents of struct :c:type:`cec_log_addrs` is invalid.
