9e7aaa7c65 selftests: mlxsw: Use shapers in QOS tests instead of forcing speed
QOS tests create congestion and verify the switch behavior. To create
congestion, they need to have more traffic than the port can handle, so
some of them force 1Gbps speed.

The tests assume that 1Gbps speed is supported, otherwise, they will fail.
Spectrum-4 ASIC will not support this speed in all ports, so to be able
to run QOS tests there, some adjustments are required. Use shapers to
limit the traffic instead of forcing speed. Note that for several ports,
the speed configuration is just for autoneg issues, so shaper is not needed
instead.

In tests that already use shapers, set the existing shaper to be a child of
a new TBF shaper which is added as a root qdisc and acts as a port shaper.

a7e85406bd selftests/bpf: Add test result messages for test_task_storage_map_stress_lookup
Add test result message when test_task_storage_map_stress_lookup()
succeeds or is skipped. The test case can be skipped due to the choose
of preemption model in kernel config, so export skips in test_maps.c and
increase it when needed.

The following is the output of test_maps when the test case succeeds or
is skipped:

  test_task_storage_map_stress_lookup:PASS
  test_maps: OK, 0 SKIPPED

  test_task_storage_map_stress_lookup SKIP (no CONFIG_PREEMPT)
  test_maps: OK, 1 SKIPPED

b18e4d4aeb KVM: arm64: selftests: Add a test case for KVM_GUESTDBG_SINGLESTEP
Add a test case for KVM_GUESTDBG_SINGLESTEP to the debug-exceptions test.
The test enables single-step execution from userspace, and check if the
exit to userspace occurs for each instruction that is stepped.
Set the default number of the test iterations to a number of iterations
sufficient to always reproduce the problem that the previous patch fixes
on an Ampere Altra machine.

ff00e73709 KVM: arm64: selftests: Refactor debug-exceptions to make it amenable to new test cases
Split up the current test into a helper, but leave the debug version
checking in main(), to make it convenient to add a new debug exception
test case in a subsequent patch.

Pull parisc architecture fixes from Helge Deller:
 "Some small parisc architecture fixes for 6.0-rc6:

  One patch lightens up a previous commit and thus unbreaks building the
  debian kernel, which tries to configure a 64-bit kernel with the
  ARCH=parisc environment variable set.

  The other patches fixes asm/errno.h includes in the tools directory
  and cleans up memory allocation in the iosapic driver.

  Summary:

   - Allow configuring 64-bit kernel with ARCH=parisc

   - Fix asm/errno.h includes in tools directory for parisc and xtensa

   - Clean up iosapic memory allocation

   - Minor typo and spelling fixes"

3e4519b7af memblock tests: add generic NUMA tests for memblock_alloc_try_nid*
Add tests for memblock_alloc_try_nid() and memblock_alloc_try_nid_raw()
where the simulated physical memory is set up with multiple NUMA nodes.
Additionally, two of these tests set nid != NUMA_NO_NODE. All tests are
run for both top-down and bottom-up allocation directions.

The tested scenarios are:

Range unrestricted:
- region cannot be allocated:
      + none of the nodes have enough memory to allocate the region

Range restricted:
- region can be allocated in the specific node requested without dropping
  min_addr:
      + the range fully overlaps with the node, and there are adjacent
        reserved regions
- region cannot be allocated:
      + nid is set to NUMA_NO_NODE and the total range can fit the region,
        but the range is split between two nodes and everything else is
        reserved

  min_addr:
      + range partially overlaps with two different nodes, where the first
        node is the requested node
      + range partially overlaps with two different nodes, where the

- region cannot be allocated in the specific node requested, but it can be

        requested node ends before min_addr
      + range overlaps with multiple nodes along node boundaries, and the

        second node is the requested node

b338bde5a3 memblock tests: add simulation of physical memory with multiple NUMA nodes
Add function setup_numa_memblock() for setting up a memory layout with
multiple NUMA nodes in a previously allocated dummy physical memory.
This function can be used in place of setup_memblock() in tests that need
to simulate a NUMA system.

setup_numa_memblock():
- allows for setting up a memory layout by specifying the fraction of
  MEM_SIZE in each node

Set CONFIG_NODES_SHIFT to 4 when building with NUMA=1 to allow for up to
16 NUMA nodes.

c8bc5e0509 selftests/bpf: Add veristat tool for mass-verifying BPF object files
Add a small tool, veristat, that allows mass-verification of
a set of *libbpf-compatible* BPF ELF object files. For each such object
file, veristat will attempt to verify each BPF program *individually*.
Regardless of success or failure, it parses BPF verifier stats and
outputs them in human-readable table format. In the future we can also
add CSV and JSON output for more scriptable post-processing, if necessary.

veristat allows to specify a set of stats that should be output and
ordering between multiple objects and files (e.g., so that one can
easily order by total instructions processed, instead of default file
name, prog name, verdict, total instructions order).

This tool should be useful for validating various BPF verifier changes
or even validating different kernel versions for regressions.

Here's an example for some of the heaviest selftests/bpf BPF object
files:

  $ sudo ./veristat -s insns,file,prog {pyperf,loop,test_verif_scale,strobemeta,test_cls_redirect,profiler}*.linked3.o

749c202cb6 libbpf: Fix crash if SEC("freplace") programs don't have attach_prog_fd set
Fix SIGSEGV caused by libbpf trying to find attach type in vmlinux BTF
for freplace programs. It's wrong to search in vmlinux BTF and libbpf
doesn't even mark vmlinux BTF as required for freplace programs. So
trying to search anything in obj->vmlinux_btf might cause NULL
dereference if nothing else in BPF object requires vmlinux BTF.

Instead, error out if freplace (EXT) program doesn't specify
attach_prog_fd during at the load time.

Update version number.

This version includes fixes for:
- fix build failure when using gcc options -Wl,--as-needed
- Fix warning for perf_cap.cpu may be uninitialized
- Fix off by one check for MAX_DIE_PER_PACKAGE
- Fix issue with use of get_physical_die_id instead of
get_physical_die_id

Optimizations:
- Removed unused interfaces and functions
- Better handle package, die, cpu combination by
defining a struct and set at one place instead
at each user level.

New functional change:
- Warn if turbo is disabled and SST turbo-freq feature is requested

7a7621dfa4 objtool,x86: Teach decode about LOOP* instructions
When 'discussing' control flow Masami mentioned the LOOP* instructions
and I realized objtool doesn't decode them properly.

As it turns out, these instructions are somewhat inefficient and as
such unlikely to be emitted by the compiler (a few vmlinux.o checks
can't find a single one) so this isn't critical, but still, best to
decode them properly.

95363747a6 tools/include/uapi: Fix <asm/errno.h> for parisc and xtensa
tools/include/uapi/asm/errno.h currently attempts to include
non-existent arch-specific errno.h header for xtensa.
Remove this case so that <asm-generic/errno.h> is used instead,
and add the missing arch-specific header for parisc.
