8c1b211985 bpf/bpftool: Add unprivileged_bpf_disabled check against value of 2
In [1], we added a kconfig knob that can set
/proc/sys/kernel/unprivileged_bpf_disabled to 2

We now check against this value in bpftool feature probe

22a41e9a50 dt-bindings: Fix missing '/schemas' in $ref paths
Absolute paths in $ref should always begin with '/schemas'. The tools
mostly work with it omitted, but for correctness the path should be
everything except the hostname as that is taken from the schema's $id
value. This scheme is defined in the json-schema spec.

a50e431bbc dt-bindings: media: mediatek,vcodec: Fix addressing cell sizes
'dma-ranges' in the example is written for cell sizes of 2 cells, but
the schema and example specify sizes of 1 cell. As the h/w has a bus
address of >32-bits, cell sizes of 2 is correct. Update the schema's
'#address-cells' and '#size-cells' to be 2 and adjust the example
throughout.

There's no error currently because dtc only checks 'dma-ranges' is a
correct multiple number of cells (3) and the schema checking is based on
bracketing of entries.

bff4e302a6 dt-bindings: display: mediatek: Fix examples on new bindings
To avoid failure of dt_binding_check perform a slight refactoring
of the examples: the main block is kept, but that required fixing
the address and size cells, plus the inclusion of missing dt-bindings
headers, required to parse some of the values assigned to various
properties.

1930a6e739 ptrace: Cleanups for v5.18
This set of changes removes tracehook.h, moves modification of all of
 the ptrace fields inside of siglock to remove races, adds a missing
 permission check to ptrace.c
 
 The removal of tracehook.h is quite significant as it has been a major
 source of confusion in recent years.  Much of that confusion was
 around task_work and TIF_NOTIFY_SIGNAL (which I have now decoupled
 making the semantics clearer).
 
 For people who don't know tracehook.h is a vestiage of an attempt to
 implement uprobes like functionality that was never fully merged, and
 was later superseeded by uprobes when uprobes was merged.  For many
 years now we have been removing what tracehook functionaly a little
 bit at a time.  To the point where now anything left in tracehook.h is
 some weird strange thing that is difficult to understand.
 
 Eric W. Biederman (15):
       ptrace: Move ptrace_report_syscall into ptrace.h
       ptrace/arm: Rename tracehook_report_syscall report_syscall

       task_work: Decouple TIF_NOTIFY_SIGNAL and task_work
       signal: Move set_notify_signal and clear_notify_signal into sched/signal.h
       resume_user_mode: Remove #ifdef TIF_NOTIFY_RESUME in set_notify_resume
       resume_user_mode: Move to resume_user_mode.h
       tracehook: Remove tracehook.h

This reverts commit d9142e1cf3.

The test is supposed to run cleanly with TLS is disabled,
to test compatibility with TCP behavior. I can't repro
the failure [1], the problem should be debugged rather
than papered over.

906b3d6491 net/smc: Send out the remaining data in sndbuf before close
The current autocork algorithms will delay the data transmission
in BH context to smc_release_cb() when sock_lock is hold by user.

So there is a possibility that when connection is being actively
closed (sock_lock is hold by user now), some corked data still
remains in sndbuf, waiting to be sent by smc_release_cb(). This
will cause:

- smc_close_stream_wait(), which is called under the sock_lock,
  has a high probability of timeout because data transmission is
  delayed until sock_lock is released.

- Unexpected data sends may happen after connction closed and use
  the rtoken which has been deleted by remote peer through
  LLC_DELETE_RKEY messages.

So this patch will try to send out the remaining corked data in
sndbuf before active close process, to ensure data integrity and
avoid unexpected data transmission after close.

6da69b1da1 net: dsa: bcm_sf2_cfp: fix an incorrect NULL check on list iterator
The bug is here:
	return rule;

The list iterator value 'rule' will *always* be set and non-NULL
by list_for_each_entry(), so it is incorrect to assume that the
iterator value will be NULL if the list is empty or no element
is found.

To fix the bug, return 'rule' when found, otherwise return NULL.

ad6dc1daaf vdpa/mlx5: Avoid processing works if workqueue was destroyed
If mlx5_vdpa gets unloaded while a VM is running, the workqueue will be
destroyed. However, vhost might still have reference to the kick
function and might attempt to push new works. This could lead to null
pointer dereference.

To fix this, set mvdev->wq to NULL just before destroying and verify
that the workqueue is not NULL in mlx5_vdpa_kick_vq before attempting to
push a new work.

This reverts commit 9e35276a53. Issue
were reported for the drivers that are using affinity managed IRQ
where manually toggling IRQ status is not expected. And we forget to
enable the interrupts in the restore path as well.

In the future, we will rework on the interrupt hardening.

c11708209d drivers/net/virtio_net: Added RSS hash report control.
Now it's possible to control supported hashflows.
Added hashflow set/get callbacks.
Also, disabling RXH_IP_SRC/DST for TCP would disable then for UDP.
TCP and UDP supports only:
ethtool -U eth0 rx-flow-hash tcp4 sd
    RXH_IP_SRC + RXH_IP_DST
ethtool -U eth0 rx-flow-hash tcp4 sdfn
    RXH_IP_SRC + RXH_IP_DST + RXH_L4_B_0_1 + RXH_L4_B_2_3
Disabling happens because VirtioNET hashtype for IP doesn't check L4 proto,
it works for all IP packets(TCP, UDP, ICMP, etc.).
For TCP and UDP, it's possible to set IP+PORT hashes.
But disabling IP hashes will disable them for TCP and UDP simultaneously.
It's possible to set IP+PORT for TCP/UDP and disable/enable IP
for everything else(UDP, ICMP, etc.).

8d65bc9a5b virtio: use virtio_device_ready() in virtio_device_restore()

    Disabling IRQ #22

This happens because we don't invoke .enable_cbs callback in
virtio_device_restore(). That callback is used by some transports
(e.g. virtio-pci) to enable interrupts.

Let's fix it, by calling virtio_device_ready() as we do in
virtio_dev_probe(). This function calls .enable_cts callback and sets
DRIVER_OK status bit.

This fix also avoids setting DRIVER_OK twice for those drivers that
call virtio_device_ready() in the .restore.

1e00e821e4 net/mlx5: Add support for configuring max device MTU
Allow an admin creating a vdpa device to specify the max MTU for the
net device.

For example, to create a device with max MTU of 1000, the following
command can be used:

$ vdpa dev add name vdpa-a mgmtdev auxiliary/mlx5_core.sf.1 mtu 1000

This configuration mechanism assumes that vdpa is the sole real user of
the function. mlx5_core could theoretically change the mtu of the
function using the ip command on the mlx5_core net device but this
should not be done.

9b3e814834 vDPA/ifcvf: implement shared IRQ feature
On some platforms/devices, there may not be enough MSI vectors
allocated for the virtqueues and config changes. In such a case,
the interrupt sources(virtqueues, config changes) must share
an IRQ/vector, to avoid initialization failures, keep
the device functional.

This commit handles three cases:
(1) number of the allocated vectors == the number of virtqueues + 1
(config changes), every virtqueue and the config interrupt has
a separated vector/IRQ, the best and the most likely case.
(2) number of the allocated vectors is less than the best case, but
greater than 1. In this case, all virtqueues share a vector/IRQ,
the config interrupt has a separated vector/IRQ
(3) only one vector is allocated, in this case, the virtqueues and
the config interrupt share a vector/IRQ. The worst and most
unlikely case.

Otherwise, it needs to fail.

This commit introduces some helper functions:
ifcvf_set_vq_vector() and ifcvf_set_config_vector() sets virtqueue
vector and config vector in the device config space, so that
the device can send interrupt DMA.
