Just ignore one more compiler warning for the bison generated C code.
Committer notes:
Older clangs don't know about -Wunused-but-set-variable, so we need to
add -Wno-unknown-warning-option to avoid this:

Currently we treat any error when reading from the child as a failure and
don't read any more output from that child as a result. This ignores the
fact that it is valid for read() to return EINTR as the error code if there
is a signal pending so we could stop handling the output of children,
especially during exit when we will get some SIGCHLD signals delivered to
us. Fix this by pulling the read handling out into a separate function
which returns a flag if reads should be continued and wrapping it in a
loop.

When fp-stress gets a termination signal it sets a flag telling itself to
exit and sends a termination signal to all the children. If the flag is set
then don't bother repeating this process, it isn't going to accomplish
anything other than consume CPU time which can be an issue when running in
emulation.

Currently we set -march=armv8.5+memtag when building the MTE selftests,
allowing the compiler to emit v8.5 and MTE instructions for anything it
generates. This means that we may get code that will generate SIGILLs when
run on older systems rather than skipping on non-MTE systems as should be
the case. Most toolchains don't select any incompatible instructions but
I have seen some reports which suggest that some may be appearing which do
so. This is also potentially problematic in that if the compiler chooses to
emit any MTE instructions for the C code it may interfere with the MTE
usage we are trying to test.
Since the only reason we are specifying this option is to allow us to
assemble MTE instructions in mte_helper.S we can avoid these issues by
moving to using a .arch directive there and adding the -march explicitly to
the toolchain support check instead of the generic CFLAGS.

We were just checking for the 'err' variable, when we should really see
if there was some of the many checked errors that don't stop the test
right away.
Detected with clang 15.0.0:
44 75.23 fedora:37 : FAIL clang version 15.0.0 (Fedora 15.0.0-2.fc37)

int err = -1, errs = 0, i, wakeups = 0;
^
1 error generated.
The patch introducing this 'perf test' entry had that check:
+ return (err < 0 || errs > 0) ? -1 : 0;
But at some point we lost that:
- return (err < 0 || errs > 0) ? -1 : 0;
+ if (err == -EACCES)
+ return TEST_SKIP;
+ if (err < 0)
+ return TEST_FAIL;
+ return TEST_OK
Put it back.

Show tid or pid of iterators if giving an argument of tid or pid
For example, the command `bpftool link list` may list following
lines.
1: iter prog 2 target_name bpf_map
2: iter prog 3 target_name bpf_prog
33: iter prog 225 target_name task_file tid 1644
pids test_progs(1644)
Link 33 is a task_file iterator with tid 1644. For now, only targets
of task, task_file and task_vma may be with tid or pid to filter out
tasks other than those belonging to a process (pid) or a thread (tid).

When synthesizing event with SPE data source, commit 4e6430cbb1a9("perf

source information by MIDR. However, is_midr_in_range only compares the
first entry in neoverse_spe.
Change is_midr_in_range to is_midr_in_range_list to traverse the
neoverse_spe array so that all neoverse cores synthesize event with data
source packet.

kernel ignored list
The testcase “vmlinux-kallsyms.c” fails in powerpc.
vmlinux symtab matches kallsyms: FAILED!
This test look at the symbols in the vmlinux DSO and check if we find
all of them in the kallsyms dso.
But from the powerpc logs , observed that the failure happens for:
ERR : 0xc0000000000fe9c8: .Lmfspr_table not on kallsyms
ERR : 0xc0000000001009c8: .Lmtspr_table not on kallsyms
These are labels ( with .L) in the source code and has to be ignored.
Reference code with .Lmtspr_table: arch/powerpc/xmon/spr_access.S
The testcases invokes is_ignored_symbol() function to ignore hidden
symbols in the dso like local symbols. This function is adapted from
is_ignored_symbol() kernel function in code: scripts/kallsyms.c . The
kernel function got some updates which is not reflected in the testcase
function and the new updates also handles ignoring "labels".
Below is the changes that went in the kernel function.
/* Symbol names that begin with the following are ignored.*/
static const char * const ignored_prefixes[] = {
"$", /* local symbols for ARM, MIPS, etc. */
- ".LASANPC", /* s390 kasan local symbols */
+ ".L", /* local labels, .LBB,.Ltmpxxx,.L__unnamed_xx,.LASANPC, etc. */
"__crc_", /* modversions */
"__efistub_", /* arm64 EFI stub namespace */
- "__kvm_nvhe_", /* arm64 non-VHE KVM namespace */
+ "__kvm_nvhe_$", /* arm64 local symbols in non-VHE KVM namespace */
+ "__kvm_nvhe_.L", /* arm64 local symbols in non-VHE KVM namespace */
"__AArch64ADRPThunk_", /* arm64 lld */
"__ARMV5PILongThunk_", /* arm lld */
"__ARMV7PILongThunk_",
This change is part of below commits and will handle the
symbols with “.L”
commit d4c858643263 ("kallsyms: ignore all local labels prefixed by '.L'")
commit 6ccf9cb557bd ("KVM: arm64: Symbolize the nVHE HYP addresses")

For PERF_SAMPLE_BRANCH_STACK sample type, different branch_sample_type,
ie branch filters are supported. The testcase "bhrb_filter_map_test"
tests the valid and invalid filter maps in different powerpc platforms.
Update this testcase to include scenario to cover multiple branch
filters at sametime. Since powerpc doesn't support multiple filters at
sametime, expect failure during perf_event_open.

Arch-specific implementations of syscall handlers are currently used
over generic implementations for the following reasons:
1. Semantics unique to powerpc
2. Compatibility syscalls require 'argument padding' to comply with
64-bit argument convention in ELF32 abi.
3. Parameter types or order is different in other architectures.
These syscall handlers have been defined prior to this patch series
without invoking the SYSCALL_DEFINE or COMPAT_SYSCALL_DEFINE macros with
custom input and output types. We remove every such direct definition in
favour of the aforementioned macros.
Also update syscalls.tbl in order to refer to the symbol names generated
by each of these macros. Since ppc64_personality can be called by both
64 bit and 32 bit binaries through compatibility, we must generate both
both compat_sys_ and sys_ symbols for this handler.
As an aside:
A number of architectures including arm and powerpc agree on an
alternative argument order and numbering for most of these arch-specific
handlers. A future patch series may allow for asm/unistd.h to signal
through its defines that a generic implementation of these syscall
handlers with the correct calling convention be emitted, through the
__ARCH_WANT_COMPAT_SYS_... convention.

Rust symbols can become quite long due to namespacing introduced
by modules, types, traits, generics, etc. For instance,
the following code:
pub mod my_module {
pub struct MyType;
pub struct MyGenericType<T>(T);
pub trait MyTrait {
fn my_method() -> u32;
}
impl MyTrait for MyGenericType<MyType> {
fn my_method() -> u32 {
42
}
}
}
generates a symbol of length 96 when using the upcoming v0 mangling scheme:
_RNvXNtCshGpAVYOtgW1_7example9my_moduleINtB2_13MyGenericTypeNtB2_6MyTypeENtB2_7MyTrait9my_method
At the moment, Rust symbols may reach up to 300 in length.
Setting 512 as the maximum seems like a reasonable choice to
keep some headroom.

Drop the requirement for system-wide kernel UAPI headers to provide full
struct btf_enum64 definition. This is an unexpected requirement that
slipped in libbpf 1.0 and put unnecessary pressure ([0]) on users to have
a bleeding-edge kernel UAPI header from unreleased Linux 6.0.
To achieve this, we forward declare struct btf_enum64. But that's not
enough as there is btf_enum64_value() helper that expects to know the
layout of struct btf_enum64. So we get a bit creative with
reinterpreting memory layout as array of __u32 and accesing lo32/hi32
fields as array elements. Alternative way would be to have a local
pointer variable for anonymous struct with exactly the same layout as
struct btf_enum64, but that gets us into C++ compiler errors complaining
about invalid type casts. So play it safe, if ugly.
