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.

+ * struct drm_property - modeset object property
+ *
+ * This structure represent a modeset object property. It combines both the name
+ * of the property with the set of permissible values. This means that when a
+ * driver wants to use a property with the same name on different objects, but
+ * with different value ranges, then it must create property for each one. An
+ * example would be rotation of &drm_plane, when e.g. the primary plane cannot
+ * be rotated. But if both the name and the value range match, then the same
+ * property structure can be instantiated multiple times for the same object.
+ * Userspace must be able to cope with this and cannot assume that the same
+ * symbolic property will have the same modeset object ID on all modeset
+ * objects.
+ *
+ * Properties are created by one of the special functions, as explained in
+ * detail in the @flags structure member.
+ *
+ * To actually expose a property it must be attached to each object using
+ * drm_object_attach_property(). Currently properties can only be attached to
+ * &drm_connector, &drm_crtc and &drm_plane.
+ *
+ * Properties are also used as the generic metadatatransport for the atomic
+ * IOCTL. Everything that was set directly in structures in the legacy modeset
+ * IOCTLs (like the plane source or destination windows, or e.g. the links to
+ * the CRTC) is exposed as a property with the DRM_MODE_PROP_ATOMIC flag set.

+	 * @flags:
+	 *
+	 * Property flags and type. A property needs to be one of the following
+	 * types:
+	 *
+	 * DRM_MODE_PROP_RANGE
+	 *     Range properties report their minimum and maximum admissible unsigned values.
+	 *     The KMS core verifies that values set by application fit in that
+	 *     range. The range is unsigned. Range properties are created using
+	 *     drm_property_create_range().
+	 *
+	 * DRM_MODE_PROP_SIGNED_RANGE
+	 *     Range properties report their minimum and maximum admissible unsigned values.
+	 *     The KMS core verifies that values set by application fit in that
+	 *     range. The range is signed. Range properties are created using
+	 *     drm_property_create_signed_range().
+	 *
+	 * DRM_MODE_PROP_ENUM
+	 *     Enumerated properties take a numerical value that ranges from 0 to
+	 *     the number of enumerated values defined by the property minus one,
+	 *     and associate a free-formed string name to each value. Applications
+	 *     can retrieve the list of defined value-name pairs and use the
+	 *     numerical value to get and set property instance values. Enum
+	 *     properties are created using drm_property_create_enum().
+	 *
+	 * DRM_MODE_PROP_BITMASK
+	 *     Bitmask properties are enumeration properties that additionally
+	 *     restrict all enumerated values to the 0..63 range. Bitmask property
+	 *     instance values combine one or more of the enumerated bits defined
+	 *     by the property. Bitmask properties are created using
+	 *     drm_property_create_bitmask().
+	 *
+	 * DRM_MODE_PROP_OBJECT
+	 *     Object properties are used to link modeset objects. This is used
+	 *     extensively in the atomic support to create the display pipeline,
+	 *     by linking &drm_framebuffer to &drm_plane, &drm_plane to
+	 *     &drm_crtc and &drm_connector to &drm_crtc. An object property can
+	 *     only link to a specific type of &drm_mode_object, this limit is
+	 *     enforced by the core. Object properties are created using
+	 *     drm_property_create_object().
+	 *
+	 *     Object properties work like blob properties, but in a more
+	 *     general fashion. They are limited to atomic drivers and must have
+	 *     the DRM_MODE_PROP_ATOMIC flag set.
+	 *
+	 * DRM_MODE_PROP_BLOB
+	 *     Blob properties store a binary blob without any format restriction.
+	 *     The binary blobs are created as KMS standalone objects, and blob
+	 *     property instance values store the ID of their associated blob
+	 *     object. Blob properties are created by calling
+	 *     drm_property_create() with DRM_MODE_PROP_BLOB as the type.
+	 *
+	 *     Actual blob objects to contain blob data are created using
+	 *     drm_property_create_blob(), or through the corresponding IOCTL.
+	 *
+	 *     Besides the built-in limit to only accept blob objects blob
+	 *     properties work exactly like object properties. The only reasons
+	 *     blob properties exist is backwards compatibility with existing
+	 *     userspace.
+	 *
+	 * In addition a property can have any combination of the below flags:
+	 *
+	 * DRM_MODE_PROP_ATOMIC
+	 *     Set for properties which encode atomic modeset state. Such
+	 *     properties are not exposed to legacy userspace.
+	 *
+	 * DRM_MODE_PROP_IMMUTABLE
+	 *     Set for properties whose values cannot be changed by
+	 *     userspace. The kernel is allowed to update the value of these
+	 *     properties. This is generally used to expose probe state to
+	 *     userspace, e.g. the EDID, or the connector path property on DP
+	 *     MST sinks. Kernel can update the value of an immutable property
+	 *     by calling drm_object_property_set_value().
