ASoC: SOF: Make sof_widget_setup/free IPC agnostic
Add 3 new topology IPC ops for widget_setup, widget_free and dai_config
in order to make the pipeline management code IPC agnostic and implement
the ops for IPC3.

Use the newly introduced tplg dai_config op to configure the DAI during
BE DAI hw_params and hw_free.

Also, in preparation for IPC4, modify BE hw_params callback to skip
setting up the DAI widget. All widgets will be set up during FW
hw_params and the DAI_CONFIG IPC should be sent only if the widget
use_count is > 0. With setting up/freeing removed from the BE hw_params,
remove the configured flag as it is no longer needed.

ASoC: SOF: set up scheduler widget before all other widgets in the pipeline
For dynamic pipelines, We set up the DAI widget during BE DAI hw_params
and this results in it getting set up before the scheduler widget for the
pipeline it belongs to is set up. Move the scheduler widget set up into
sof_widget_setup() to ensure that the scheduler widget is always the first
widget in a pipeline to be set up and the last one to get freed after all
the other widgets have been freed.

8f9e7b65f8 block: cancel all throttled bios in del_gendisk()
Throttled bios can't be issued after del_gendisk() is done, thus
it's better to cancel them immediately rather than waiting for
throttle is done.

For example, if user thread is throttled with low bps while it's
issuing large io, and the device is deleted. The user thread will
wait for a long time for io to return.

0a9a25ca78 block: let blkcg_gq grab request queue's refcnt
In the whole lifetime of blkcg_gq instance, ->q will be referred, such
as, ->pd_free_fn() is called in blkg_free, and throtl_pd_free() still
may touch the request queue via &tg->service_queue.pending_timer which
is handled by throtl_pending_timer_fn(), so it is reasonable to grab
request queue's refcnt by blkcg_gq instance.

Previously blkcg_exit_queue() is called from blk_release_queue, and it
is hard to avoid the use-after-free. But recently commit 1059699f87 ("block:
move blkcg initialization/destroy into disk allocation/release handler")
is merged to for-5.18/block, it becomes simple to fix the issue by simply
grabbing request queue's refcnt.

ee37eddbfa block: avoid use-after-free on throttle data
In throtl_pending_timer_fn(), request queue is retrieved from throttle
data. And tg's pending timer is deleted synchronously when releasing the
associated blkg, at that time, throttle data may have been freed since
commit 1059699f87 ("block: move blkcg initialization/destroy into disk
allocation/release handler") moves freeing q->td to disk_release() from
blk_release_queue(). So use-after-free on q->td in throtl_pending_timer_fn
can be triggered.

Fixes the issue by:

- do nothing in case that disk is released, when there isn't any bio to
  dispatch

- retrieve request queue from blkg instead of throttle data for
non top-level pending timer.

It is not recommened to use platform_get_resource(pdev, IORESOURCE_IRQ)
for requesting IRQ's resources any more, as they can be not ready yet in
case of DT-booting.

platform_get_irq() instead is a recommended way for getting IRQ even if
it was not retrieved earlier.

It also makes code simpler because we're getting "int" value right away
and no conversion from resource to int is required.

6487d1dab8 ptrace: Return the signal to continue with from ptrace_stop
The signal a task should continue with after a ptrace stop is
inconsistently read, cleared, and sent.  Solve this by reading and
clearing the signal to be sent in ptrace_stop.

In an ideal world everything except ptrace_signal would share a common
implementation of continuing with the signal, so ptracers could count
on the signal they ask to continue with actually being delivered.  For
now retain bug compatibility and just return with the signal number
the ptracer requested the code continue with.

63cc8e20b3 Merge branch 'bpf-fix-sock-field-tests'
Jakub Sitnicki says:

====================
I think we have reached a consensus [1] on how the test for the 4-byte load from
bpf_sock->dst_port and bpf_sk_lookup->remote_port should look, so here goes v3.

I will submit a separate set of patches for bpf_sk_lookup->remote_port tests.

This series has been tested on x86_64 and s390 on top of recent bpf-next -
ad13baf456 ("selftests/bpf: Test subprog jit when toggle bpf_jit_harden
repeatedly").

  [1] https://lore.kernel.org/bpf/87k0cwxkzs.fsf@cloudflare.com/

v2 -> v3:
- Split what was previously patch 2 which was doing two things
- Use BPF_TCP_* constants (Martin)
- Treat the result of 4-byte load from dst_port as a 16-bit value (Martin)
- Typo fixup and some rewording in patch 4 description
v1 -> v2:
- Limit read_sk_dst_port only to client traffic (patch 2)
- Make read_sk_dst_port pass on litte- and big-endian (patch 3)

v1: https://lore.kernel.org/bpf/20220225184130.483208-1-jakub@cloudflare.com/

deb5940046 selftests/bpf: Fix test for 4-byte load from dst_port on big-endian
The check for 4-byte load from dst_port offset into bpf_sock is failing on
big-endian architecture - s390. The bpf access converter rewrites the
4-byte load to a 2-byte load from sock_common at skc_dport offset, as shown
below.

  * s390 / llvm-objdump -S --no-show-raw-insn

  00000000000002a0 <sk_dst_port__load_word>:
        84:       r1 = *(u32 *)(r1 + 48)
        85:       w0 = 1
        86:       if w1 == 51966 goto +1 <LBB5_2>
        87:       w0 = 0
  00000000000002c0 <LBB5_2>:
        88:       exit

  * s390 / bpftool prog dump xlated

  _Bool sk_dst_port__load_word(struct bpf_sock * sk):
    35: (69) r1 = *(u16 *)(r1 +12)
    36: (bc) w1 = w1
    37: (b4) w0 = 1
    38: (16) if w1 == 0xcafe goto pc+1
    39: (b4) w0 = 0
    40: (95) exit

  * x86_64 / llvm-objdump -S --no-show-raw-insn

  00000000000002a0 <sk_dst_port__load_word>:
        84:       r1 = *(u32 *)(r1 + 48)
        85:       w0 = 1
        86:       if w1 == 65226 goto +1 <LBB5_2>
        87:       w0 = 0
  00000000000002c0 <LBB5_2>:
        88:       exit

  * x86_64 / bpftool prog dump xlated

  _Bool sk_dst_port__load_word(struct bpf_sock * sk):
    33: (69) r1 = *(u16 *)(r1 +12)
    34: (b4) w0 = 1
    35: (16) if w1 == 0xfeca goto pc+1
    36: (b4) w0 = 0
    37: (95) exit

This leads to surprises if we treat the destination register contents as a
32-bit value, ignoring the fact that in reality it contains a 16-bit value.

On little-endian the register contents reflect the bpf_sock struct
definition, where the lower 16-bits contain the port number:

	struct bpf_sock {
		...
		__be16 dst_port;	/* offset 48 */
		__u16 :16;
		...
	};

However, on big-endian the register contents suggest that field the layout
of bpf_sock struct is as so:

	struct bpf_sock {
		...
		__u16 :16;		/* offset 48 */
		__be16 dst_port;
		...
	};

Account for this quirky access conversion in the test case exercising the
4-byte load by treating the result as 16-bit wide.

2d2202ba85 selftests/bpf: Check dst_port only on the client socket
cgroup_skb/egress programs which sock_fields test installs process packets
flying in both directions, from the client to the server, and in reverse
direction.

Recently added dst_port check relies on the fact that destination
port (remote peer port) of the socket which sends the packet is known ahead
of time. This holds true only for the client socket, which connects to the
known server port.

Filter out any traffic that is not egressing from the client socket in the
BPF program that tests reading the dst_port.

a4c9fe0ed4 selftests/bpf: Fix error reporting from sock_fields programs
The helper macro that records an error in BPF programs that exercise sock
fields access has been inadvertently broken by adaptation work that
happened in commit b18c1f0aa4 ("bpf: selftest: Adapt sock_fields test to
use skel and global variables").

BPF_NOEXIST flag cannot be used to update BPF_MAP_TYPE_ARRAY. The operation
always fails with -EEXIST, which in turn means the error never gets
recorded, and the checks for errors always pass.

Revert the change in update flags.

336d4b814b ptrace: Move setting/clearing ptrace_message into ptrace_stop
Today ptrace_message is easy to overlook as it not a core part of
ptrace_stop.  It has been overlooked so much that there are places
that set ptrace_message and don't clear it, and places that never set
it.  So if you get an unlucky sequence of events the ptracer may be
able to read a ptrace_message that does not apply to the current
ptrace stop.

Move setting of ptrace_message into ptrace_stop so that it always gets
set before the stop, and always gets cleared after the stop.  This
prevents non-sense from being reported to userspace and makes
ptrace_message more visible in the ptrace helper functions so that
kernel developers can see it.
