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
well as using '*' wildcard in test/subtests selection. '-a' and '-t' can
co-exists, same as '-d' and '-b', in which case they just add to the list of
allowed or denied test selectors.
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
subtests will also be executed.

This patch add test name in subtest status message line, making it possible to
grep ':OK' in the output to generate a list of passed test+subtest names, which
can be processed to generate argument list to be used with "-a", "-d" exact
string matching.

..
#1/12 align/pointer variable subtraction:OK

In skip_account(), test->skip_cnt is set to 0 at the end, this makes next print

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
flexibility to GCC.
For that add an entry to the exception table so that
program_check_exception() knowns where to resume execution
after a WARNING.
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.
We've got some WARN_ON() in .softirqentry.text section so it needs
to be added in the OTHER_TEXT_SECTIONS in modpost.c

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.

perf_test_util is used to set up KVM selftests where vCPUs touch a
region of memory. The guest code is implemented in perf_test_util.c (not
the calling selftests). The guest code requires a 1 parameter, the
vcpuid, which has to be set by calling vcpu_args_set(vm, vcpu_id, 1,
vcpu_id).
Today all of the selftests that use perf_test_util are making this call.
Instead, perf_test_util should just do it. This will save some code but
more importantly prevents mistakes since totally non-obvious that this
needs to be called and failing to do so results in vCPUs not accessing
the right regions of memory.

Introduce a new option to dirty_log_perf_test: -x number_of_slots. This
causes the test to attempt to split the region of memory into the given
number of slots. If the region cannot be evenly divided, the test will

This allows testing with more than one slot and therefore measure how
performance scales with the number of memslots.

Pull kvm fixes from Paolo Bonzini:
"Mostly bugfixes; plus, support for XMM arguments to Hyper-V hypercalls
now obeys KVM_CAP_HYPERV_ENFORCE_CPUID.
Both the XMM arguments feature and KVM_CAP_HYPERV_ENFORCE_CPUID are
new in 5.14, and each did not know of the other"

To verify that this hash implements the Toeplitz hash function.
Additionally, provide a script toeplitz.sh to run the test in loopback mode
on a networking device of choice (see setup_loopback.sh). Since the
script modifies the NIC setup, it will not be run by selftests
automatically.
Tested:
./toeplitz.sh -i eth0 -irq_prefix <eth0_pattern> -t -6

Implement a GRO testsuite that expects Linux kernel GRO behavior.
All tests pass with the kernel software GRO stack. Run against a device
with hardware GRO to verify that it matches the software stack.
gro.c generates packets and sends them out through a packet socket. The
receiver in gro.c (run separately) receives the packets on a packet
socket, filters them by destination ports using BPF and checks the
packet geometry to see whether GRO was applied.
gro.sh provides a wrapper to run the gro.c in NIC loopback mode.
It is not included in continuous testing because it modifies network
configuration around a physical NIC: gro.sh sets the NIC in loopback
mode, creates macvlan devices on the physical device in separate
namespaces, and sends traffic generated by gro.c between the two
namespaces to observe coalescing behavior.
GRO coalescing is time sensitive.
Some tests may prove flaky on some hardware.
Note that this test suite tests for software GRO unless hardware GRO is
enabled (ethtool -K $DEV rx-gro-hw on).
To test, run ./gro.sh.
The wrapper will output success or failed test names, and generate
log.txt and stderr.
Sample log.txt result:
...
pure data packet of same size: Test succeeded
large data packets followed by a smaller one: Test succeeded
small data packets followed by a larger one: Test succeeded
...
Sample stderr result:
...
carrier ready
running test ipv4 data
Expected {200 }, Total 1 packets
Received {200 }, Total 1 packets.

Rewrite to skel and ASSERT macros as well while we are at it.
v3:
- replace -f with -A to make it work with busybox ping.
-A is available on both busybox and iputils, from the man page:
On networks with low RTT this mode is essentially equivalent to
flood mode.
v2:
- don't check result of bpf_map__fd (Yonghong Song)
- remove from .gitignore (Andrii Nakryiko)
- move ping_command into network_helpers (Andrii Nakryiko)
- remove assert() (Andrii Nakryiko)

The test was mistakenly using addr_gpa2hva on a gva and that happened
to work accidentally. Commit 106a2e766eae ("KVM: selftests: Lower the
min virtual address for misc page allocations") revealed this bug.

Recently we added multi-queue support to netdevsim in commit d4861fc6be58
("netdevsim: Add multi-queue support"); add a few control-plane selftests
for sch_mq using this new feature.
Use nsPlugin.py to avoid network interface name collisions.

1) Fix a sysbot reported memory leak in xfrm_user_rcv_msg.
From Pavel Skripkin.
2) Revert "xfrm: policy: Read seqcount outside of rcu-read side
in xfrm_policy_lookup_bytype". This commit tried to fix a
lockin bug, but only cured some of the symptoms. A proper
fix is applied on top of this revert.
3) Fix a locking bug on xfrm state hash resize. A recent change
on sequence counters accidentally repaced a spinlock by a mutex.
Fix from Frederic Weisbecker.
4) Fix possible user-memory-access in xfrm_user_rcv_msg_compat().
From Dmitry Safonov.
5) Add initialiation sefltest fot xfrm_spdattr_type_t.

This patch adds OOB support for AF_UNIX sockets.
The semantics is same as TCP.
The last byte of a message with the OOB flag is
treated as the OOB byte. The byte is separated into
a skb and a pointer to the skb is stored in unix_sock.
The pointer is used to enforce OOB semantics.
