Introduce a test for aarch64 that ensures CPU resets induced by PSCI are
reflected in the target vCPU's state, even if the target is never run
again. This is a regression test for a race between vCPU migration and
PSCI.

libbpf CI has reported send_signal test is flaky although
I am not able to reproduce it in my local environment.
But I am able to reproduce with on-demand libbpf CI ([1]).
Through code analysis, the following is possible reason.
The failed subtest runs bpf program in softirq environment.
Since bpf_send_signal() only sends to a fork of "test_progs"
process. If the underlying current task is
not "test_progs", bpf_send_signal() will not be triggered
and the subtest will fail.
To reduce the chances where the underlying process is not
the intended one, this patch boosted scheduling priority to
-20 (highest allowed by setpriority() call). And I did
10 runs with on-demand libbpf CI with this patch and I
didn't observe any failures.

This patch adds '-a' and '-d' arguments supporting both exact string match as

co-exists, same as '-d' and '-b', in which case they just add to the list of

Caveat: Same as the current substring matching mechanism, test and subtest
selector applies independently, 'a*/b*' will execute all tests matching "a*",
and with subtest name matching "b*", but tests matching "a*" that has no

As previously discussed with David Ahern, here is a refactored and improved
version of the IOAM self-test. It is now more complete and more robust. Now,
all tests are divided into three categories: OUTPUT (evaluates the IOAM
processing by the sender), INPUT (evaluates the IOAM processing by the receiver)
and GLOBAL (evaluates wider use cases that do not fall into the other two
categories). Both OUTPUT and INPUT tests only use a two-node topology (alpha and
beta), while GLOBAL tests use the entire three-node topology (alpha, beta,
gamma). Each test is documented inside its own handler in the (bash) script.

Extend attach_probe selftests to specify ref_ctr_offset for uprobe/uretprobe
and validate that its value is incremented from zero.
Turns out that once uprobe is attached with ref_ctr_offset, uretprobe for the
same location/function *has* to use ref_ctr_offset as well, otherwise
perf_event_open() fails with -EINVAL. So this test uses ref_ctr_offset for
both uprobe and uretprobe, even though for the purpose of test uprobe would be
enough.

Add selftest with few subtests testing proper bpf_cookie usage.
Kprobe and uprobe subtests are pretty straightforward and just validate that
the same BPF program attached with different bpf_cookie will be triggered with
those different bpf_cookie values.
Tracepoint subtest is a bit more interesting, as it is the only
perf_event-based BPF hook that shares bpf_prog_array between multiple
perf_events internally. This means that the same BPF program can't be attached
to the same tracepoint multiple times. So we have 3 identical copies. This
arrangement allows to test bpf_prog_array_copy()'s handling of bpf_prog_array
list manipulation logic when programs are attached and detached. The test
validates that bpf_cookie isn't mixed up and isn't lost during such list
manipulations.
Perf_event subtest validates that two BPF links can be created against the
same perf_event (but not at the same time, only one BPF program can be
attached to perf_event itself), and that for each we can specify different
bpf_cookie value.

Using asm goto in __WARN_FLAGS() and WARN_ON() allows more

For that add an entry to the exception table so that

Here are two exemples. The first one is done on PPC32 (which
benefits from the previous patch), the second is on PPC64.
unsigned long test(struct pt_regs *regs)
{
int ret;
WARN_ON(regs->msr & MSR_PR);
return regs->gpr[3];
}
unsigned long test9w(unsigned long a, unsigned long b)
{
if (WARN_ON(!b))
return 0;
return a / b;
}

In the first exemple, we see GCC doesn't need to duplicate what
happens after the trap.
In the second exemple, we see that GCC doesn't need to emit a test
and a branch in the likely path in addition to the trap.

Currently weak typeless ksyms have default value zero, when they don't
exist in the kernel. However, weak typed ksyms are rejected by libbpf
if they can not be resolved. This means that if a bpf object contains
the declaration of a nonexistent weak typed ksym, it will be rejected
even if there is no program that references the symbol.
Nonexistent weak typed ksyms can also default to zero just like
typeless ones. This allows programs that access weak typed ksyms to be
accepted by verifier, if the accesses are guarded. For example,
extern const int bpf_link_fops3 __ksym __weak;
/* then in BPF program */
if (&bpf_link_fops3) {
/* use bpf_link_fops3 */
}
If actual use of nonexistent typed ksym is not guarded properly,
verifier would see that register is not PTR_TO_BTF_ID and wouldn't
allow to use it for direct memory reads or passing it to BPF helpers.

The program type cannot be deduced from 'tx' which causes an invalid
argument error when trying to load xdp_tx.o using the skeleton.
Rename the section name to "xdp" so that libbpf can deduce the type.
