3a755cd8b7 bonding: add new option lacp_active
Add an option lacp_active, which is similar with team's runner.active.
This option specifies whether to send LACPDU frames periodically. If set
on, the LACPDU frames are sent along with the configured lacp_rate
setting. If set off, the LACPDU frames acts as "speak when spoken to".

Note, the LACPDU state frames still will be sent when init or unbind port.

v2: remove module parameter

3d9d00bd18 net: bonding: move ioctl handling to private ndo operation
All other user triggered operations are gone from ndo_ioctl, so move
the SIOCBOND family into a custom operation as well.

The .ndo_ioctl() helper is no longer called by the dev_ioctl.c code now,
but there are still a few definitions in obsolete wireless drivers as well
as the appletalk and ieee802154 layers to call SIOCSIFADDR/SIOCGIFADDR
helpers from inside the kernel.

In order to further reduce the scope of ndo_do_ioctl(), move

function.

Adjust the prototype to only pass the if_settings sub-structure

in the process.

a76053707d dev_ioctl: split out ndo_eth_ioctl
Most users of ndo_do_ioctl are ethernet drivers that implement
the MII commands SIOCGMIIPHY/SIOCGMIIREG/SIOCSMIIREG, or hardware
timestamping with SIOCSHWTSTAMP/SIOCGHWTSTAMP.

Separate these from the few drivers that use ndo_do_ioctl to
implement SIOCBOND, SIOCBR and SIOCWANDEV commands.

This is a purely cosmetic change intended to help readers find
their way through the implementation.

b9067f5dc4 net: split out SIOCDEVPRIVATE handling from dev_ioctl
SIOCDEVPRIVATE ioctl commands are mainly used in really old
drivers, and they have a number of problems:

- They hide behind the normal .ndo_do_ioctl function that
  is also used for other things in modern drivers, so it's
  hard to spot a driver that actually uses one of these

- Since drivers use a number different calling conventions,
  it is impossible to support compat mode for them in
  a generic way.

- With all drivers using the same 16 commands codes, there
  is no way to introspect the data being passed through
  things like strace.

Add a new net_device_ops callback pointer, to address the
first two of these. Separating them from .ndo_do_ioctl
makes it easy to grep for drivers with a .ndo_siocdevprivate
callback, and the unwieldy name hopefully makes it easier
to spot in code review.

By passing the ifreq structure and the ifr_data pointer
separately, it is no longer necessary to overload these,
and the driver can use either one for a given command.

====================
pull-request: can-next 2021-07-25

this is a pull request of 46 patches for net-next/master.

The first 6 patches target the CAN J1939 protocol. One is from
gushengxian, fixing a grammatical error, 5 are by me fixing a checkpatch
warning, make use of the fallthrough pseudo-keyword, and use
consistent variable naming.

The next 3 patches target the rx-offload helper, are by me and improve
the performance and fix the local softirq work pending error, when
napi_schedule() is called from threaded IRQ context.

The next 3 patches are by Vincent Mailhol and me update the CAN
bittiming and transmitter delay compensation, the documentation for
the struct can_tdc is fixed, clear data_bittiming if FD mode is turned
off and a redundant check is removed.

Followed by 4 patches targeting the m_can driver. Faiz Abbas's patches
add support for CAN PHY via the generic phy subsystem. Yang Yingliang
converts the driver to use devm_platform_ioremap_resource_byname().
And a patch by me which removes the unused support for custom bit
timing.

Andy Shevchenko contributes 2 patches for the mcp251xfd driver to
prepare the driver for ACPI support. A patch by me adds support for
shared IRQ handlers.

Zhen Lei contributes 3 patches to convert the esd_usb2, janz-ican3 and
the at91_can driver to make use of the DEVICE_ATTR_RO/RW() macros.

The next 8 patches are by Peng Li and provide general cleanups for the
at91_can driver.

The next 7 patches target the peak driver. Frist 2 cleanup patches by
me for the peak_pci driver, followed by Stephane Grosjean' patch to
print the name and firmware version of the detected hardware. The
peak_usb driver gets a cleanup patch, loopback and one-shot mode and
an upgrading of the bus state change handling in Stephane Grosjean's
patches.

Vincent Mailhol provides 6 cleanup patches for the etas_es58x driver.

In the last 3 patches Angelo Dureghello add support for the mcf5441x
SoC to the flexcan driver.

However, that is further constrained with an if clause that require
exactly two interrupts, even though it might not make sense on those
devices or in some setups.

Let's remove the clause entirely.

e71e2ace57 userfaultfd: do not untag user pointers
Patch series "userfaultfd: do not untag user pointers", v5.

If a user program uses userfaultfd on ranges of heap memory, it may end
up passing a tagged pointer to the kernel in the range.start field of
the UFFDIO_REGISTER ioctl.  This can happen when using an MTE-capable
allocator, or on Android if using the Tagged Pointers feature for MTE
readiness [1].

When a fault subsequently occurs, the tag is stripped from the fault
address returned to the application in the fault.address field of struct
uffd_msg.  However, from the application's perspective, the tagged
address *is* the memory address, so if the application is unaware of
memory tags, it may get confused by receiving an address that is, from
its point of view, outside of the bounds of the allocation.  We observed
this behavior in the kselftest for userfaultfd [2] but other
applications could have the same problem.

Address this by not untagging pointers passed to the userfaultfd ioctls.
Instead, let the system call fail.  Also change the kselftest to use
mmap so that it doesn't encounter this problem.

[1] https://source.android.com/devices/tech/debug/tagged-pointers
[2] tools/testing/selftests/vm/userfaultfd.c

This patch (of 2):

Do not untag pointers passed to the userfaultfd ioctls.  Instead, let
the system call fail.  This will provide an early indication of problems
with tag-unaware userspace code instead of letting the code get confused
later, and is consistent with how we decided to handle brk/mmap/mremap
in commit dcde237319e6 ("mm: Avoid creating virtual address aliases in
brk()/mmap()/mremap()"), as well as being consistent with the existing
tagged address ABI documentation relating to how ioctl arguments are
handled.

The code change is a revert of commit 7d0325749a6c ("userfaultfd: untag
user pointers") plus some fixups to some additional calls to
validate_range that have appeared since then.

1e3bac71c5 tracing/histogram: Rename "cpu" to "common_cpu"
Currently the histogram logic allows the user to write "cpu" in as an
event field, and it will record the CPU that the event happened on.

The problem with this is that there's a lot of events that have "cpu"
as a real field, and using "cpu" as the CPU it ran on, makes it
impossible to run histograms on the "cpu" field of events.

For example, if I want to have a histogram on the count of the
workqueue_queue_work event on its cpu field, running:

 ># echo 'hist:keys=cpu' > events/workqueue/workqueue_queue_work/trigger

Gives a misleading and wrong result.

Change the command to "common_cpu" as no event should have "common_*"
fields as that's a reserved name for fields used by all events. And
this makes sense here as common_cpu would be a field used by all events.

Now we can even do:

 ># echo 'hist:keys=common_cpu,cpu if cpu < 100' > events/workqueue/workqueue_queue_work/trigger
 ># cat events/workqueue/workqueue_queue_work/hist
 # event histogram
 #
 # trigger info: hist:keys=common_cpu,cpu:vals=hitcount:sort=hitcount:size=2048 if cpu < 100 [active]
 #

 { common_cpu:          0, cpu:          2 } hitcount:          1
 { common_cpu:          0, cpu:          4 } hitcount:          1
 { common_cpu:          7, cpu:          7 } hitcount:          1
 { common_cpu:          0, cpu:          7 } hitcount:          1
 { common_cpu:          0, cpu:          1 } hitcount:          1
 { common_cpu:          0, cpu:          6 } hitcount:          2
 { common_cpu:          0, cpu:          5 } hitcount:          2
 { common_cpu:          1, cpu:          1 } hitcount:          4
 { common_cpu:          6, cpu:          6 } hitcount:          4
 { common_cpu:          5, cpu:          5 } hitcount:         14
 { common_cpu:          4, cpu:          4 } hitcount:         26
 { common_cpu:          0, cpu:          0 } hitcount:         39
 { common_cpu:          2, cpu:          2 } hitcount:        184

Now for backward compatibility, I added a trick. If "cpu" is used, and
the field is not found, it will fall back to "common_cpu" and work as
it did before. This way, it will still work for old programs that use
"cpu" to get the actual CPU, but if the event has a "cpu" as a field, it
will get that event's "cpu" field, which is probably what it wants
anyway.

I updated the tracefs/README to include documentation about both the
common_timestamp and the common_cpu. This way, if that text is present in
the README, then an application can know that common_cpu is supported over
just plain "cpu".

213ad73d06 tcp: disable TFO blackhole logic by default
Multiple complaints have been raised from the TFO users on the internet
stating that the TFO blackhole logic is too aggressive and gets falsely
triggered too often.
(e.g. https://blog.apnic.net/2021/07/05/tcp-fast-open-not-so-fast/)
Considering that most middleboxes no longer drop TFO packets, we decide
to disable the blackhole logic by setting
/proc/sys/net/ipv4/tcp_fastopen_blackhole_timeout_set to 0 by default.

de8e80a54c ipv6: ioam: Documentation for new IOAM sysctls
Add documentation for new IOAM sysctls:
 - ioam6_id and ioam6_id_wide: two per-namespace sysctls
 - ioam6_enabled, ioam6_id and ioam6_id_wide: three per-interface sysctls

Example of IOAM configuration based on the following simple topology:

 _____              _____              _____
|     | eth0  eth0 |     | eth1  eth0 |     |
|  A  |.----------.|  B  |.----------.|  C  |
|_____|            |_____|            |_____|

1) Node and interface IDs can be configured for IOAM:

  # IOAM ID of A = 1, IOAM ID of A.eth0 = 11
  (A) sysctl -w net.ipv6.ioam6_id=1
  (A) sysctl -w net.ipv6.conf.eth0.ioam6_id=11

  # IOAM ID of B = 2, IOAM ID of B.eth0 = 21, IOAM ID of B.eth1 = 22
  (B) sysctl -w net.ipv6.ioam6_id=2
  (B) sysctl -w net.ipv6.conf.eth0.ioam6_id=21
  (B) sysctl -w net.ipv6.conf.eth1.ioam6_id=22

  # IOAM ID of C = 3, IOAM ID of C.eth0 = 31
  (C) sysctl -w net.ipv6.ioam6_id=3
  (C) sysctl -w net.ipv6.conf.eth0.ioam6_id=31

  Note that "_wide" IDs equivalents can be configured the same way.

2) Each node can be configured to form an IOAM domain. For instance,
   we allow IOAM from A to C only (not the reverse path), i.e. enable
   IOAM on ingress for B.eth0 and C.eth0:

  (B) sysctl -w net.ipv6.conf.eth0.ioam6_enabled=1
  (C) sysctl -w net.ipv6.conf.eth0.ioam6_enabled=1

3) An IOAM domain (e.g. ID=123) is defined and made known to each node:

  (A) ip ioam namespace add 123
  (B) ip ioam namespace add 123
  (C) ip ioam namespace add 123

4) Finally, an IOAM Pre-allocated Trace can be inserted in traffic sent
   by A when C (e.g. db02::2) is the destination:

  (A) ip -6 route add db02::2/128 encap ioam6 trace type 0x800000 ns 123
      size 12 dev eth0

1d67c8d993 ARM: SoC fixes for v5.14
Here are the patches for this week that came as the fallout of
 the merge window:
 
  - Two fixes for the NVidia memory controller driver
 
  - multiple defconfig files get patched to turn CONFIG_FB back on
    after that is no longer selected by CONFIG_DRM
 
  - ffa and scmpi firmware drivers fixes, mostly addressing compiler
    and documentation warnings
 
  - Platform specific fixes for device tree files on ASpeed,
    Renesas and NVidia SoC, mostly for recent regressions.
 
  - A workaround for a regression on the USB PHY with devlink when
    the usb-nop-xceiv driver is not available until the rootfs is
    mounted.

50d8d7e19c dt-bindings: display: renesas,du: Make resets optional on R-Car H1
The "resets" property is not present on R-Car Gen1 SoCs.
Supporting it would require migrating from renesas,cpg-clocks to
renesas,cpg-mssr.

Reflect this in the DT bindings by removing the global "required:
