Linus Torvalds
9d31d23389 Networking changes for 5.13.
Core:
 
  - bpf:
 	- allow bpf programs calling kernel functions (initially to
 	  reuse TCP congestion control implementations)
 	- enable task local storage for tracing programs - remove the
 	  need to store per-task state in hash maps, and allow tracing
 	  programs access to task local storage previously added for
 	  BPF_LSM
 	- add bpf_for_each_map_elem() helper, allowing programs to
 	  walk all map elements in a more robust and easier to verify
 	  fashion
 	- sockmap: support UDP and cross-protocol BPF_SK_SKB_VERDICT
 	  redirection
 	- lpm: add support for batched ops in LPM trie
 	- add BTF_KIND_FLOAT support - mostly to allow use of BTF
 	  on s390 which has floats in its headers files
 	- improve BPF syscall documentation and extend the use of kdoc
 	  parsing scripts we already employ for bpf-helpers
 	- libbpf, bpftool: support static linking of BPF ELF files
 	- improve support for encapsulation of L2 packets
 
  - xdp: restructure redirect actions to avoid a runtime lookup,
 	improving performance by 4-8% in microbenchmarks
 
  - xsk: build skb by page (aka generic zerocopy xmit) - improve
 	performance of software AF_XDP path by 33% for devices
 	which don't need headers in the linear skb part (e.g. virtio)
 
  - nexthop: resilient next-hop groups - improve path stability
 	on next-hops group changes (incl. offload for mlxsw)
 
  - ipv6: segment routing: add support for IPv4 decapsulation
 
  - icmp: add support for RFC 8335 extended PROBE messages
 
  - inet: use bigger hash table for IP ID generation
 
  - tcp: deal better with delayed TX completions - make sure we don't
 	give up on fast TCP retransmissions only because driver is
 	slow in reporting that it completed transmitting the original
 
  - tcp: reorder tcp_congestion_ops for better cache locality
 
  - mptcp:
 	- add sockopt support for common TCP options
 	- add support for common TCP msg flags
 	- include multiple address ids in RM_ADDR
 	- add reset option support for resetting one subflow
 
  - udp: GRO L4 improvements - improve 'forward' / 'frag_list'
 	co-existence with UDP tunnel GRO, allowing the first to take
 	place correctly	even for encapsulated UDP traffic
 
  - micro-optimize dev_gro_receive() and flow dissection, avoid
 	retpoline overhead on VLAN and TEB GRO
 
  - use less memory for sysctls, add a new sysctl type, to allow using
 	u8 instead of "int" and "long" and shrink networking sysctls
 
  - veth: allow GRO without XDP - this allows aggregating UDP
 	packets before handing them off to routing, bridge, OvS, etc.
 
  - allow specifing ifindex when device is moved to another namespace
 
  - netfilter:
 	- nft_socket: add support for cgroupsv2
 	- nftables: add catch-all set element - special element used
 	  to define a default action in case normal lookup missed
 	- use net_generic infra in many modules to avoid allocating
 	  per-ns memory unnecessarily
 
  - xps: improve the xps handling to avoid potential out-of-bound
 	accesses and use-after-free when XPS change race with other
 	re-configuration under traffic
 
  - add a config knob to turn off per-cpu netdev refcnt to catch
 	underflows in testing
 
 Device APIs:
 
  - add WWAN subsystem to organize the WWAN interfaces better and
    hopefully start driving towards more unified and vendor-
    -independent APIs
 
  - ethtool:
 	- add interface for reading IEEE MIB stats (incl. mlx5 and
 	  bnxt support)
 	- allow network drivers to dump arbitrary SFP EEPROM data,
 	  current offset+length API was a poor fit for modern SFP
 	  which define EEPROM in terms of pages (incl. mlx5 support)
 
  - act_police, flow_offload: add support for packet-per-second
 	policing (incl. offload for nfp)
 
  - psample: add additional metadata attributes like transit delay
 	for packets sampled from switch HW (and corresponding egress
 	and policy-based sampling in the mlxsw driver)
 
  - dsa: improve support for sandwiched LAGs with bridge and DSA
 
  - netfilter:
 	- flowtable: use direct xmit in topologies with IP
 	  forwarding, bridging, vlans etc.
 	- nftables: counter hardware offload support
 
  - Bluetooth:
 	- improvements for firmware download w/ Intel devices
 	- add support for reading AOSP vendor capabilities
 	- add support for virtio transport driver
 
  - mac80211:
 	- allow concurrent monitor iface and ethernet rx decap
 	- set priority and queue mapping for injected frames
 
  - phy: add support for Clause-45 PHY Loopback
 
  - pci/iov: add sysfs MSI-X vector assignment interface
 	to distribute MSI-X resources to VFs (incl. mlx5 support)
 
 New hardware/drivers:
 
  - dsa: mv88e6xxx: add support for Marvell mv88e6393x -
 	11-port Ethernet switch with 8x 1-Gigabit Ethernet
 	and 3x 10-Gigabit interfaces.

 	  (21% improvement for 1000B UDP frames)
 	- support XDP even without dedicated Tx queues - share the Tx
 	  queues with the stack when necessary
 
  - mlx5:
 	- flow rules: add support for mirroring with conntrack,
 	  matching on ICMP, GTP, flex filters and more
 	- support packet sampling with flow offloads
 	- persist uplink representor netdev across eswitch mode
 	  changes
 	- allow coexistence of CQE compression and HW time-stamping

35655ceb31 Here's a collection of largely clk driver updates for the merge window. The
usual suspects are here: i.MX, Qualcomm, Renesas, Allwinner, Samsung, and
 Rockchip, but it feels pretty light on commits. There's only one real commit to
 the framework core and that's to consolidate code. Otherwise the diffstat is
 dominated by many Qualcomm clk driver patches that modernize the driver for the
 proper way of speciying clk parents. That's shifting data around, which could
 subtly break things so I'll be on the lookout for fixes.
 
 New Drivers:
  - Proper clk driver for Mediatek MT7621 SoCs
  - Support for the clock controller on the new Rockchip rk3568
 
 Updates:
  - Simplify Zynq Kconfig dependencies
  - Use clk_hw pointers in socfpga driver
  - Cleanup parent data in qcom clk drivers
  - Some cleanups for rk3399 modularization
  - Fix reparenting of i.MX UART clocks by initializing only the ones
    associated to stdout
  - Correct the PCIE clocks for i.MX8MP and i.MX8MQ
  - Make i.MX LPCG and SCU clocks return on registering failure
  - Kernel doc fixes
  - Add DAB hardware accelerator clocks on Renesas R-Car E3 and M3-N
  - Add timer (TMU) clocks on Renesas R-Car H3 ES1.0
  - Add Timer (TMU & CMT) and thermal sensor (TSC) clocks on Renesas R-Car V3U
  - Sigma-delta modulation on Allwinner V3s audio PLL

 "The usual lots of work all over the place.

  i915 has gotten some Alderlake work and prelim DG1 code, along with a
  major locking rework over the GEM code, and brings back the property

  Alderbran support (new GPU), freesync HDMI support along with a lot
  other fixes.

Merge tag 'printk-for-5.13' of git://git.kernel.org/pub/scm/linux/kernel/git/printk/linux

Pull printk updates from Petr Mladek:

 - Stop synchronizing kernel log buffer readers by logbuf_lock. As a
   result, the access to the buffer is fully lockless now.

   Note that printk() itself still uses locks because it tries to flush
   the messages to the console immediately. Also the per-CPU temporary
   buffers are still there because they prevent infinite recursion and
   serialize backtraces from NMI. All this is going to change in the
   future.

 - kmsg_dump API rework and cleanup as a side effect of the logbuf_lock
   removal.

 - Make bstr_printf() aware that %pf and %pF formats could deference the
   given pointer.

 - Show also page flags by %pGp format.

 - Clarify the documentation for plain pointer printing.

 - Do not show no_hash_pointers warning multiple times.

 - Update Senozhatsky email address.

 - Some clean up.

4a0225c3d2 spi: Updates for v5.13
The only core work for SPI this time around is the completion of the
 conversion to the new style method for specifying transfer delays,
 meaning we can cope with what most controllers support more directly
 using conversions in the core rather than open coding in drivers.
 Otherwise it's a good stack of cleanups and fixes plus a few new
 drivers.
 
 The conversion to new style transfer delay will cause an issue with a
 newly added staging driver which has a straightforward resolution in
 -next.
 
  - Completion of the conversion to new style transfer delay
    configuration.
  - Introduction and use of module_parport_driver() helper, merged here
    as there's no parport tree.
  - Support for Altera SoCs on DFL buses, NXP i.MX8DL, HiSilicon Kunpeng,
    MediaTek MT8195,

47080f2286 hwmon updates for v5.13
The most notable change is the removal of the amd_energy driver. It was
 rendered all but unusable by making its attributes privileged-only to work
 around a security issue. A suggested remedy was rejected by AMD, so the
 only real solution was to remove the driver. For the future, we'll have
 to make sure that no privileged-access-only drivers are accepted into the
 hwmon subsystem in the first place. The hwmon ABI document was updated
 accordingly.
 
 Other changes:
 
 PMBus drivers:
 - Added driver for MAX15301
 - Added driver for BluTek BPA-RS600
 - Added driver for fsp-3y PSUs and PDUs
 - Added driver for Infineon IR36021
 - Added driver for ST STPDDC60
 - Added support for TI TPS53676 to tps53679 driver
 - Introduced PMBUS symbol namespace
   This was made necessary by a suggestion to use its exported functions
   from outside the hwmon subsystem.
 - Minor improvements and bug fixes
 
 New drivers:
 - Driver for NZXT Kraken X42/X52/X62/X72
 
 Driver enhancements:
 - Added support for Intel D5005 to intel-m10-bmc-hwmon driver
 - Added support for NCT6686D to nct6683 driver
 
 Other:
 - Converted sch5627 and amd9240 drivers to hwmon_device_register_with_info()
 - Added support for fan drawers capability and present registers to mlxreg-fan
   driver
 - Added Dell Latitude E7440 to fan control whitelist in dell-smm driver
 - Replaced snprintf in show functions with sysfs_emit
   Done with coccinelle script for all drivers to preempt endless per-driver
   submissions of the same change.
 - Use kobj_to_dev()
   Another coccinelle based change to preempt endless per-driver submissions
   of the same change.

0c85556318 ARM: platform support for Apple M1
The Apple M1 is the processor used it all current generation Apple
 Macintosh computers. Support for this platform so far is rudimentary,
 but it boots and can use framebuffer and serial console over a special
 USB cable.
 
 Support for several essential on-chip devices (USB, PCIe, IOMMU, NVMe)
 is work in progress but was not ready in time.
 
 A very detailed description of what works is in the merge commit
 and on the AsahiLinux wiki.

6b0fbc540c ARM: platform support for Nuvoton WPCM450
The Nuvoton WPCM450 BMC is an older chip based on the ARM926 CPU core
 that remains in use on Supermicro X9 server boards among others. Support
 gets added for a particular server board using this SoC along with the
 basic platform bringup.
 
 As the platform is a predecessor to the npcm7xx platform we already
 support, it is added to the same directory, despite using a different
 name. It also seems to be related to the older w90x900/nuc9xx platform
 that was removed last year.

01d7136894 ARM: SoC changes for v5.13
Almost all SoC code changes this time are for the TI OMAP
 platform, which continues its decade-long quest to move from
 describing a complex SoC in code to device tree.
 
 Aside from this, the Uniphier platform has a new maintainer
 and some platforms have minor bugfixes and cleanups that were
 not urgent enough for v5.12.

d08410d8c9 TTY/Serial driver updates for 5.13-rc1
Here is the big set of tty and serial driver updates for 5.13-rc1.
 
 Actually busy this release, with a number of cleanups happening:
 	- much needed core tty cleanups by Jiri Slaby
 	- removal of unused and orphaned old-style serial drivers.  If
 	  anyone shows up with this hardware, it is trivial to restore
 	  these but we really do not think they are in use anymore.
 	- fixes and cleanups from Johan Hovold on a number of termios
 	  setting corner cases that loads of drivers got wrong as well
 	  as removing unneeded code due to tty core changes from long
 	  ago that were never propagated out to the drivers
 	- loads of platform-specific serial port driver updates and
 	  fixes
 	- coding style cleanups and other small fixes and updates all
 	  over the tty/serial tree.
 
 All of these have been in linux-next for a while now with no reported
 issues.

8900d92fd6 Staging/IIO driver updates for 5.13-rc1
Here is the big set of staging and IIO driver updates for 5.13-rc1.
 
 Lots of little churn in here, and some larger churn as well.  Major
 things are:
 	- removal of wimax drivers, no one has this hardware anymore for
 	  this failed "experiment".
 	- removal of the Google gasket driver, turns out no one wanted
 	  to maintain it or cares about it anymore, so they asked for it
 	  to be removed.
 	- comedi finally moves out of the staging directory into
 	  drivers/comedi/  This is one of the oldest kernel subsystems
 	  around, being created in the 2.0 kernel days, and was one of
 	  the first things added to drivers/staging/ when that was
 	  created over 15 years ago.  It should have been moved out of
 	  staging a long time ago, it's well maintained and used by
 	  loads of different devices in the real world every day.  Nice
 	  to see this finally happen.
 	- so many tiny coding style cleanups it's not funny.  Perfect
 	  storm of at least 2 different intern project application
 	  deadlines combined to provide a huge number of new
 	  contributions in this area from people learning how to do
 	  kernel development.  Great job to everyone involved here.
 
 There's also the normal updates for IIO drivers with new IIO drivers and
 updates all over that subsystem.
 
 All of these have been in linux-next for a while with no reported
 issues.

Here is the "big" set of driver core changes for 5.13-rc1.

 things are:
 	- finally set fw_devlink=on by default.  All reported issues
 	  with this have been shaken out over the past 9 months or so,
 	  but we will be paying attention to any fallout here in case we
 	  need to revert this as the default boot value (symptoms of

 	- fixes found to be needed by fw_devlink=on value in some
 	  subsystems (like clock).
 	- delayed work initialization cleanup
 	- driver core cleanups and minor updates
 	- software node cleanups and tweaks
 	- devtmpfs cleanups

spi: brcm,spi-bcm-qspi: convert to the json-schema
This helps validating DTS files.

Changes that require mentioning:
1. reg-names
   "mspi_regs" and "bspi_regs" were renamed to "mspi" and "bspi" as that
   is what's used in DTS files and in Linux driver
2. interrupt-names
   Names were reordered. "mspi_done" has to go first as it's always
   required.
3. spi-rx-bus-width
   Property description was dropped as it's part of the
   spi-controller.yaml
4. Examples:
   * drop partitions as they are well documented elsewhere
   * regs and interrupts were formatted and reordered to match yaml
   * <0x1c> was replaced with <&gic>
   * "m25p80" node name became "flash"
   * dropped invalid "m25p,fast-read" property
   * dropped undocumented and Linux-unused "clock-names"

This rewritten binding validates cleanly using the  "dt_binding_check".
Some Linux stored DTS files will require reordering regs and interrupts
to make dtbs_check happy.

9049572fb1 hwmon: Remove amd_energy driver
Commit 60268b0e82 ("hwmon: (amd_energy) modify the visibility of
the counters") restricted visibility of AMD energy counters to work
around a side-channel attack using energy data to determine which
instructions are executed. The attack is described in 'PLATYPUS:
Software-based Power Side-Channel Attacks on x86'. It relies on quick
and accurate energy readings.

This change made the counters provided by the amd_energy driver
effectively unusable for non-provileged users. However, unprivileged
read access is the whole point of hardware monitoring attributes.

An attempt to remedy the situation by limiting and randomizing access
to chip registers was rejected by AMD. Since the driver is for all
practical purposes unusable, remove it.

Add pmbus driver support for Maxim MAX15301 InTune Automatically
Compensated Digital PoL Controller with Driver and PMBus Telemetry

Even though the specification does not specifically mention it,
extensive empirical testing has revealed that auto-detection of
limit-registers will fail in a random fashion unless the delay
parameter is set to above about 80us. The default delay is set
to 100us to include some safety margin.

This patch is tested on a Flex BMR461 converter module.

82e3430dfa hwmon: add driver for NZXT Kraken X42/X52/X62/X72
These are "all-in-one" CPU liquid coolers that can be monitored and
controlled through a proprietary USB HID protocol.

While the models have differently sized radiators and come with varying
numbers of fans, they are all indistinguishable at the software level.

The driver exposes fan/pump speeds and coolant temperature through the
standard hwmon sysfs interface.

Fan and pump control, while supported by the devices, are not currently
exposed.  The firmware accepts up to 61 trip points per channel
(fan/pump), but the same set of trip temperatures has to be maintained
for both; with pwmX_auto_point_Y_temp attributes, users would need to
maintain this invariant themselves.

Instead, fan and pump control, as well as LED control (which the device
also supports for 9 addressable RGB LEDs on the CPU water block) are
left for existing and already mature user-space tools, which can still
be used alongside the driver, thanks to hidraw.  A link to one, which I
also maintain, is provided in the documentation.

The implementation is based on USB traffic analysis.  It has been
runtime tested on x86_64, both as a built-in driver and as a module.

5ffe04ccd6 ARM SoC fixes for v5.12, part 2
Another smaller set of fixes for three of the Arm platforms:
 
 TI OMAP:
 
     Fix swapped mmc device order also for omap3 that got changed with the
     recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the aliases
     should be board specific, all the mmc device instances are all there in
     the SoC, and we do probe them by default so that PM runtime can idle the
     devices if left enabled from the bootloader.
 
 Qualcomm Snapdragon:
 
     This bypasses the, recently introduced, interconnect handling in the
     GENI (serial engine) driver when running off ACPI, as this causes the
     GENI probe to fail and the Lenovo Yoga C630 to boot without keyboard
     and touchpad.
 
 Allwinner:
 
     One 32kHz clock fix for the beelink gs1, a CD polarity fix for the SoPine,
     some MAINTAINERS maintainance, and a clk / reset switch to our headers.

Merge tag 'arm-fixes-5.12-3' of git://git.kernel.org/pub/scm/linux/kernel/git/soc/soc

Pull ARM SoC fixes from Arnd Bergmann:
 "Another smaller set of fixes for three of the Arm platforms:

  TI OMAP:

     Fix swapped mmc device order also for omap3 that got changed with
     the recent PROBE_PREFER_ASYNCHRONOUS changes. While eventually the
     aliases should be board specific, all the mmc device instances are
     all there in the SoC, and we do probe them by default so that PM
     runtime can idle the devices if left enabled from the bootloader.

  Qualcomm Snapdragon:

     This bypasses the recently introduced interconnect handling in
     the GENI (serial engine) driver when running off ACPI, as this
     causes the GENI probe to fail and the Lenovo Yoga C630 to boot
     without keyboard and touchpad.

  Allwinner:

     One 32kHz clock fix for the beelink gs1, a CD polarity fix for the
     SoPine, some MAINTAINERS maintainance, and a clk / reset switch to
     our headers"

88a5af9439 Networking fixes for 5.12-rc8, including fixes from netfilter,
and bpf. BPF verifier changes stand out, otherwise things have
 slowed down.
 
 Current release - regressions:
 
  - gro: ensure frag0 meets IP header alignment
 
  - Revert "net: stmmac: re-init rx buffers when mac resume back"
 
  - ethernet: macb: fix the restore of cmp registers
 
 Previous releases - regressions:
 
  - ixgbe: Fix NULL pointer dereference in ethtool loopback test
 
  - ixgbe: fix unbalanced device enable/disable in suspend/resume
 
  - phy: marvell: fix detection of PHY on Topaz switches
 
  - make tcp_allowed_congestion_control readonly in non-init netns
 
  - xen-netback: Check for hotplug-status existence before watching
 
 Previous releases - always broken:
 
  - bpf: mitigate a speculative oob read of up to map value size by
         tightening the masking window
 
  - sctp: fix race condition in sctp_destroy_sock
 
  - sit, ip6_tunnel: Unregister catch-all devices
 
  - netfilter: nftables: clone set element expression template
 
  - netfilter: flowtable: fix NAT IPv6 offload mangling
 
  - net: geneve: check skb is large enough for IPv4/IPv6 header
 
  - netlink: don't call ->netlink_bind with table lock held
