ASoC: Fixes for v6.19

We've been quite busy with fixes since the merge window, though not in
any particularly exciting ways - the standout thing is the fix for _SX
controls which were broken by a change to how we do clamping, otherwise
it's all fairly run of the mill fixes and quirks.

====================
selftests/bpf: convert test_tc_edt.sh into test_progs

Hello,
this is a (late) v2 to my first attempt to convert the test_tc_edt
script to test_progs. This new version is way simpler, thanks to
Martin's suggestion about properly using the existing network_helpers
rather than reinventing the wheel. It also fixes a small bug in the
measured effective rate.

The converted test roughly follows the original script logic, with two
veths in two namespaces, a TCP connection between a client and a server,
and the client pushing a specific amount of data. Time is recorded
before and after the transmission to compute the effective rate.

There are two knobs driving the robustness of the test in CI:
- the amount of pushed data (the higher, the more precise is the
effective rate)
- the tolerated error margin

The original test was configured with a 20s duration and a 1% error
margin. The new test is configured with 1MB of data being pushed and a
2% error margin, to:
- make the duration tolerable in CI
- while keeping enough margin for rate measure fluctuations depending on
the CI machines load

This has been run multiple times locally to ensure that those values are
sane, and once in CI before sending the series, but I suggest to let it
live a few days in CI to see how it really behaves.

Merge branch 'bpf-indirect-jumps'

Anton Protopopov says:

====================
BPF indirect jumps

This patchset implements a new type of map, instruction set, and uses
it to build support for indirect branches in BPF (on x86). (The same
map will be later used to provide support for indirect calls and static
keys.) See [1], [2] for more context.

Short table of contents:

* Patches 1-6 implement the new map of type
BPF_MAP_TYPE_INSN_SET and corresponding selftests. This map can
be used to track the "original -> xlated -> jitted mapping" for
a given program.

* Patches 7-12 implement the support for indirect jumps on x86 and add libbpf
support for LLVM-compiled programs containing indirect jumps, and selftests.

The jump table support was merged to LLVM and now can be
enabled with -mcpu=v4, see [3]. The __BPF_FEATURE_GOTOX
macros can be used to check if the compiler supports the
feature or not.

See individual patches for more details on the implementation details.

v10 -> v11 (this series):

* rearranged patches and split libbpf patch such that first 6 patches
implementing instruction arrays can be applied independently

RFC -> v1 (https://lore.kernel.org/bpf/20250816180631.952085-1-a.s.protopopov@gmail.com/):

* I've tried to address all the comments provided by Alexei and
Eduard in RFC. Will try to list the most important of them below.
* One big change: move from older LLVM version [5] to newer [4].
Now LLVM generates jump tables as symbols in the new special
section ".jumptables". Another part of this change is that
libbpf now doesn't try to link map load and goto *rX, as
1) this is absolutely not reliable 2) for some use cases this
is impossible (namely, when more than one jump table can be used
in the same gotox instruction).
* Added insn_successors() support (Alexei, Eduard). This includes
getting rid of the ugly bpf_insn_set_iter_xlated_offset()
interface (Eduard).
* Removed hack for the unreachable instruction, as new LLVM thank to
Eduard doesn't generate it.
* Set mem_size for direct map access properly instead of hacking.
Remove off>0 check. (Alexei)
* Do not allocate new memory for min_index/max_index (Alexei, Eduard)
* Information required during check_cfg is now cached to be reused
later (Alexei + general logic for supporting multiple JT per jump)
* Properly compare registers in regsafe (Alexei, Eduard)
* Remove support for JMP32 (Eduard)
* Better checks in adjust_ptr_min_max_vals (Eduard)
* More selftests were added (but still there's room for more) which
directly use gotox (Alexei)
* More checks and verbose messages added
* "unique pointers" are no more in the map

Add C-level selftests for indirect jumps to validate LLVM and libbpf
functionality. The tests are intentionally disabled, to be run
locally by developers, but will not make the CI red.

====================
selftests/bpf: Integrate test_xsk.c to test_progs framework

The test_xsk.sh script covers many AF_XDP use cases. The tests it runs
are defined in xksxceiver.c. Since this script is used to test real
hardware, the goal here is to leave it as it is, and only integrate the
tests that run on veth peers into the test_progs framework.

PATCH 1 extracts test_xsk[.c/.h] from xskxceiver[.c/.h] to make the
tests available to test_progs.
PATCH 2 to 7 fix small issues in the current test
PATCH 8 to 13 handle all errors to release resources instead of calling
exit() when any error occurs.
PATCH 14 isolates the tests that won't fit in the CI
PATCH 15 integrates the CI tests to the test_progs framework

Merge branch 'selftests-bpf-convert-test_tc_tunnel-sh-to-test_progs'

Alexis Lothoré says:

====================
Hello,
this is the v3 of test_tc_tunnel conversion into test_progs framework.
This new revision:
- fixes a few issues spotted by the bot reviewer
- removes any test ensuring connection failure (and so depending on a
timout) to keep the execution time reasonable

test_tc_tunnel.sh tests a variety of tunnels based on BPF: packets are
encapsulated by a BPF program on the client egress. We then check that
those packets can be decapsulated on server ingress side, either thanks
to kernel-based or BPF-based decapsulation. Those tests are run thanks
to two veths in two dedicated namespaces.

- patches 1 and 2 are preparatory patches
- patch 3 introduce tc_tunnel test into test_progs
- patch 4 gets rid of the test_tc_tunnel.sh script

The new test has been executed both in some x86 local qemu machine, as
well as in CI:

__maybe_unused for the variables, but it is better to just add the option
-Wno-unused-but-set-variable to CFLAGS in Makefile to disable the errors
instead of hacking the tests.
