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.

+================================
+Intel 810/815 Framebuffer driver
+================================
+
+Tony Daplas <adaplas@pol.net>
+
+http://i810fb.sourceforge.net
+
+March 17, 2002
+
+First Released: July 2001
+Last Update:    September 12, 2005
+
+A. Introduction
+===============
+
+	This is a framebuffer driver for various Intel 810/815 compatible
+	graphics devices.  These include:
+
+	- Intel 810
+	- Intel 810E
+	- Intel 810-DC100
+	- Intel 815 Internal graphics only, 100Mhz FSB
+	- Intel 815 Internal graphics only
+	- Intel 815 Internal graphics and AGP
+
+B.  Features
+============
+
+	- Choice of using Discrete Video Timings, VESA Generalized Timing
+	  Formula, or a framebuffer specific database to set the video mode
+
+	- Supports a variable range of horizontal and vertical resolution and
+	  vertical refresh rates if the VESA Generalized Timing Formula is
+	  enabled.
+
+	- Supports color depths of 8, 16, 24 and 32 bits per pixel
+
+	- Supports pseudocolor, directcolor, or truecolor visuals
+
+	- Full and optimized hardware acceleration at 8, 16 and 24 bpp
+
+	- Robust video state save and restore
+
+	- MTRR support
+
+	- Utilizes user-entered monitor specifications to automatically
+	  calculate required video mode parameters.
+
+	- Can concurrently run with xfree86 running with native i810 drivers
+
+	- Hardware Cursor Support
+
+	- Supports EDID probing either by DDC/I2C or through the BIOS
+
+C.  List of available options
+=============================
+
+   a. "video=i810fb"
+	enables the i810 driver
+
+	Recommendation: required
+
+   b. "xres:<value>"
+	select horizontal resolution in pixels. (This parameter will be
+	ignored if 'mode_option' is specified.  See 'o' below).
+
+	Recommendation: user preference
+	(default = 640)
+
+   c. "yres:<value>"
+	select vertical resolution in scanlines. If Discrete Video Timings
+	is enabled, this will be ignored and computed as 3*xres/4.  (This
+	parameter will be ignored if 'mode_option' is specified.  See 'o'
+	below)
+
+	Recommendation: user preference
+	(default = 480)
+
+   d. "vyres:<value>"
+	select virtual vertical resolution in scanlines. If (0) or none
+	is specified, this will be computed against maximum available memory.
+
+	Recommendation: do not set
+	(default = 480)
+
+   e. "vram:<value>"
+	select amount of system RAM in MB to allocate for the video memory
+
+	Recommendation: 1 - 4 MB.
+	(default = 4)
+
+   f. "bpp:<value>"
+	select desired pixel depth
+
+	Recommendation: 8
+	(default = 8)
+
+   g. "hsync1/hsync2:<value>"
+	select the minimum and maximum Horizontal Sync Frequency of the
+	monitor in kHz.  If using a fixed frequency monitor, hsync1 must
+	be equal to hsync2. If EDID probing is successful, these will be
+	ignored and values will be taken from the EDID block.
+
+	Recommendation: check monitor manual for correct values
+	(default = 29/30)
+
+   h. "vsync1/vsync2:<value>"
+	select the minimum and maximum Vertical Sync Frequency of the monitor
+	in Hz. You can also use this option to lock your monitor's refresh
+	rate. If EDID probing is successful, these will be ignored and values
+	will be taken from the EDID block.
+
+	Recommendation: check monitor manual for correct values
+	(default = 60/60)
+
+	IMPORTANT:  If you need to clamp your timings, try to give some
+	leeway for computational errors (over/underflows).  Example: if
+	using vsync1/vsync2 = 60/60, make sure hsync1/hsync2 has at least
+	a 1 unit difference, and vice versa.
+
+   i. "voffset:<value>"
+	select at what offset in MB of the logical memory to allocate the
+	framebuffer memory.  The intent is to avoid the memory blocks
+	used by standard graphics applications (XFree86).  The default
+	offset (16 MB for a 64 MB aperture, 8 MB for a 32 MB aperture) will
+	avoid XFree86's usage and allows up to 7 MB/15 MB of framebuffer
+	memory.  Depending on your usage, adjust the value up or down
+	(0 for maximum usage, 31/63 MB for the least amount).  Note, an
+	arbitrary setting may conflict with XFree86.
+
+	Recommendation: do not set
+	(default = 8 or 16 MB)
+
+   j. "accel"
+	enable text acceleration.  This can be enabled/reenabled anytime
+	by using 'fbset -accel true/false'.
+
+	Recommendation: enable
+	(default = not set)
+
+   k. "mtrr"
+	enable MTRR.  This allows data transfers to the framebuffer memory
+	to occur in bursts which can significantly increase performance.
+	Not very helpful with the i810/i815 because of 'shared memory'.
+
+	Recommendation: do not set
+	(default = not set)
+
+   l. "extvga"
+	if specified, secondary/external VGA output will always be enabled.
+	Useful if the BIOS turns off the VGA port when no monitor is attached.
+	The external VGA monitor can then be attached without rebooting.
+
+	Recommendation: do not set
+	(default = not set)
+
+   m. "sync"
+	Forces the hardware engine to do a "sync" or wait for the hardware
+	to finish before starting another instruction. This will produce a
+	more stable setup, but will be slower.
+
+	Recommendation: do not set
+	(default = not set)
+
+   n. "dcolor"
+	Use directcolor visual instead of truecolor for pixel depths greater
+	than 8 bpp.  Useful for color tuning, such as gamma control.
+
+	Recommendation: do not set
+	(default = not set)
+
+   o. <xres>x<yres>[-<bpp>][@<refresh>]
+	The driver will now accept specification of boot mode option.  If this
+	is specified, the options 'xres' and 'yres' will be ignored. See
+	Documentation/fb/modedb.rst for usage.
+
+D. Kernel booting
+=================
+
+Separate each option/option-pair by commas (,) and the option from its value
+with a colon (:) as in the following::
+
+	video=i810fb:option1,option2:value2
+
+Sample Usage
+------------
+
+In /etc/lilo.conf, add the line::
+
+  append="video=i810fb:vram:2,xres:1024,yres:768,bpp:8,hsync1:30,hsync2:55, \
+	  vsync1:50,vsync2:85,accel,mtrr"
+
+This will initialize the framebuffer to 1024x768 at 8bpp.  The framebuffer
+will use 2 MB of System RAM. MTRR support will be enabled. The refresh rate
+will be computed based on the hsync1/hsync2 and vsync1/vsync2 values.
+
+IMPORTANT:
+  You must include hsync1, hsync2, vsync1 and vsync2 to enable video modes
+  better than 640x480 at 60Hz. HOWEVER, if your chipset/display combination
+  supports I2C and has an EDID block, you can safely exclude hsync1, hsync2,
+  vsync1 and vsync2 parameters.  These parameters will be taken from the EDID
+  block.
+
+E.  Module options
+==================
+
+The module parameters are essentially similar to the kernel
+parameters. The main difference is that you need to include a Boolean value
+(1 for TRUE, and 0 for FALSE) for those options which don't need a value.
+
+Example, to enable MTRR, include "mtrr=1".
+
+Sample Usage
+------------
+
+Using the same setup as described above, load the module like this::
+
+	modprobe i810fb vram=2 xres=1024 bpp=8 hsync1=30 hsync2=55 vsync1=50 \
+		 vsync2=85 accel=1 mtrr=1
+
+Or just add the following to a configuration file in /etc/modprobe.d/::
+
+	options i810fb vram=2 xres=1024 bpp=16 hsync1=30 hsync2=55 vsync1=50 \
+	vsync2=85 accel=1 mtrr=1
+
+and just do a::
+
+	modprobe i810fb
+
+
+F.  Setup
+=========
+
+	a. Do your usual method of configuring the kernel
+
+	   make menuconfig/xconfig/config
+
+	b. Under "Code maturity level options" enable "Prompt for development
+	   and/or incomplete code/drivers".
+
+	c. Enable agpgart support for the Intel 810/815 on-board graphics.
+	   This is required.  The option is under "Character Devices".
+
+	d. Under "Graphics Support", select "Intel 810/815" either statically
+	   or as a module.  Choose "use VESA Generalized Timing Formula" if
+	   you need to maximize the capability of your display.  To be on the
+	   safe side, you can leave this unselected.
+
+	e. If you want support for DDC/I2C probing (Plug and Play Displays),
+	   set 'Enable DDC Support' to 'y'. To make this option appear, set
+	   'use VESA Generalized Timing Formula' to 'y'.
+
+	f. If you want a framebuffer console, enable it under "Console
+	   Drivers".
+
+	g. Compile your kernel.
+
+	h. Load the driver as described in sections D and E.
+
+	i.  Try the DirectFB (http://www.directfb.org) + the i810 gfxdriver
+	    patch to see the chipset in action (or inaction :-).
