selftests: mptcp: lib: skip if missing symbol
Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
New functions are now available to easily detect if a certain feature is
missing by looking at kallsyms.
These new helpers are going to be used in the following commits. In
order to ease the backport of such future patches, it would be good if
this patch is backported up to the introduction of MPTCP selftests,
hence the Fixes tag below: this type of check was supposed to be done
from the beginning.

bpf: netfilter: Add BPF_NETFILTER bpf_attach_type
Andrii Nakryiko writes:
And we currently don't have an attach type for NETLINK BPF link.
Thankfully it's not too late to add it. I see that link_create() in
kernel/bpf/syscall.c just bypasses attach_type check. We shouldn't
have done that. Instead we need to add BPF_NETLINK attach type to enum
bpf_attach_type. And wire all that properly throughout the kernel and
libbpf itself.
This adds BPF_NETFILTER and uses it. This breaks uabi but this
wasn't in any non-rc release yet, so it should be fine.
v2: check link_attack prog type in link_create too

selftests/ftrace: Choose target function for filter test from samples
Since the event-filter-function.tc expects the 'exit_mmap()' directly
calls 'kmem_cache_free()', this is vulnerable to code modifications.
Choose the target function for the filter test from the sample
event data so that it can keep test running correctly even if the caller
function name will be changed.

KVM: selftests: Add test for race in kvm_recalculate_apic_map()
Keep switching between LAPIC_MODE_X2APIC and LAPIC_MODE_DISABLED during APIC map construction to hunt for TOCTOU bugs in KVM. KVM's optimized map recalc makes multiple passes over the list of vCPUs, and the calculations ignore vCPU's whose APIC is hardware-disabled, i.e. there's a window where toggling LAPIC_MODE_DISABLED is quite interesting.

- Remove the use of llvm-strip on BPF skel object files, not needed, fixes a

selftests: mptcp: join: avoid using 'cmp --bytes'
BusyBox's 'cmp' command doesn't support the '--bytes' parameter.
Some CIs -- i.e. LKFT -- use BusyBox and have the mptcp_join.sh test
failing [1] because their 'cmp' command doesn't support this '--bytes'
option:
cmp: unrecognized option '--bytes=1024'
BusyBox v1.35.0 () multi-call binary.
Usage: cmp [-ls] [-n NUM] FILE1 [FILE2]
Instead, 'head --bytes' can be used as this option is supported by
BusyBox. A temporary file is needed for this operation.
Because it is apparently quite common to use BusyBox, it is certainly
better to backport this fix to impacted kernels.

Tracing fixes:
User events:
- Use long instead of int for storing the enable set/clear bit, as it was
found that big endian machines could end up using the wrong bits.
- Split allocating mm and attaching it. This keeps the allocation separate
from the registration and avoids various races.
- Remove RCU locking around pin_user_pages_remote() as that can schedule. The
RCU protection is no longer needed with the above split of mm allocation and
attaching.
- Rename the "link" fields of the various structs to something more
meaningful.
- Add comments around user_event_mm struct usage and locking requirements.
Timerlat tracer:
- Fix missed wakeup of timerlat thread caused by the timerlat interrupt
triggering when tracing is off. The timer interrupt handler needs to always
wake up the timerlat thread regardless if tracing is enabled or not,
otherwise, it will never wake up.
Histograms:
- Fix regression of breaking the "stacktrace" modifier for variables. That
modifier cannot be used for values, but can be used for variables that are
passed from one histogram to the next. This was broken when adding the
restriction to values as the variable logic used the same code.
- Rename the special field "stacktrace" to "common_stacktrace". Special fields
(that are not actually part of the event, but can act just like event
fields, like 'comm' and 'timestamp') should be prefixed with 'common_' for
consistency. To keep backward compatibility, 'stacktrace' can still be used
(as with the special field 'cpu'), but can be overridden if the event has a
field called 'stacktrace'.
- Update the synthetic event selftests to use the new name (synthetic events
are created by histograms)
Tracing bootup selftests:
- Reorganize the code to keep artifacts of the selftests not compiled in when
selftests are not configured.
- Add various cond_resched() around the selftest code, as the softlock
watchdog was triggering much more often. It appears that the kernel runs
slower now with full debugging enabled.
- While debugging ftrace with ftrace (using an instance ring buffer instead of
the top level one), I found that the selftests were disabling prints to the
debug instance. This should not happen, as the selftests only disable
printing to the main buffer as the selftests examine the main buffer to see
if it has what it expects, and prints can make the tests fail. Make the
selftests only disable printing to the toplevel buffer, and leave the
instance buffers alone.

Error: cpu-clock event does not have sample flags 66c660
failed to set filter "(null)" on event cpu-clock with 2 (No such file or directory)

tracing/selftests: Update synthetic event selftest to use common_stacktrace
With the rename of the stacktrace field to common_stacktrace, update the selftests to reflect this change. Copy the current selftest to test the backward compatibility "stacktrace" keyword. Also the "requires" of that test was incorrect, so it would never actually ran before. That is fixed now.

bpf, sockmap: Test FIONREAD returns correct bytes in rx buffer with drops
When BPF program drops pkts the sockmap logic 'eats' the packet and updates copied_seq. In the PASS case where the sk_buff is accepted we update copied_seq from recvmsg path so we need a new test to handle the drop case. Original patch series broke this resulting in test_sockmap_skb_verdict_fionread:PASS:ioctl(FIONREAD) error 0 nsec test_sockmap_skb_verdict_fionread:FAIL:ioctl(FIONREAD) unexpected ioctl(FIONREAD): actual 1503041772 != expected 256 After updated patch with fix.

bpf, sockmap: Test FIONREAD returns correct bytes in rx buffer
A bug was reported where ioctl(FIONREAD) returned zero even though the socket with a SK_SKB verdict program attached had bytes in the msg queue. The result is programs may hang or more likely try to recover, but use suboptimal buffer sizes. Add a test to check that ioctl(FIONREAD) returns the correct number of bytes.

bpf, sockmap: Build helper to create connected socket pair
A common operation for testing is to spin up a pair of sockets that are connected. Then we can use these to run specific tests that need to send data, check BPF programs and so on.

perf tools fixes for v6.4:
- Fail graciously if BUILD_BPF_SKEL=1 is specified and clang isn't available.
- Add empty 'struct rq' to 'perf lock contention' to satisfy libbpf 'runqueue'
type verification. This feature is built only with BUILD_BPF_SKEL=1.
- Make vmlinux.h use bpf.h and perf_event.h in source directory, not system
ones that may be old and not have things like 'union perf_sample_weight'.
- Add system include paths to BPF builds to pick things missing in the headers
included by clang -target bpf.
- Update various header copies with the kernel sources.
- Change divide by zero and not supported events behavior to show 'nan'/'not
counted' in 'perf stat' output. This happens when using things like
'perf stat -M TopdownL2 true', involving JSON metrics.
- Update no event/metric expectations affected by using JSON metrics in
'perf stat -ddd' perf test.
- Avoid segv with 'perf stat --topdown' for metrics without a group.
- Do not assume which events may have a PMU name, allowing the logic to keep an
AUX event group together. Makes this usecase work again:

- Add a check for the above use case in 'perf test test_intel_pt'.
- Fix build with refcount checking on arm64, it was still accessing fields that
need to be wrapped so that the refcounted struct gets checked.
- Fix contextid validation in ARM's CS-ETM, so that older kernels without that
field can still be supported.
- Skip unsupported aggregation for stat events found in perf.data files in 'perf script'.
- Add stat test for record and script to check the previous problem.
- Remove needless debuginfod queries from 'perf test java symbol', this was
just making the test take a long time to complete.
- Address python SafeConfigParser() deprecation warning in 'perf test attr'.
- Fix __NR_execve undeclared on i386 'perf bench syscall' build error.

driver is registered already when it starts (Petr Pavlu).
- Make cpupower read TSC on each CPU right before reading MPERF so as

accesses and improve the C0 percentage calculation (Wyes Karny).
- Fix a possible file handle leak and clean up the code in the

This cpupower fixes update for Linux 67.4-rc3 consists of: - a resource leak fix - fix drift in C0 percentage calculation due to System-wide TSC read. To lower this drift read TSC per CPU and also just after mperf read. This technique improves C0 percentage calculation in Mperf monitor -----BEGIN PGP SIGNATURE----- iQIzBAABCgAdFiEEPZKym/RZuOCGeA/kCwJExA0NQxwFAmRlGnYACgkQCwJExA0N Qxx80A//RtYobNoT+VANs3ZWoioGF1r0l4abxRXgGOTIPe+CsPtYF1OT3eUyj1as 2VoOdt6UT4X46RkGmgcyAYJon9tVaINVVm0ssk2zyXBsbf5NyNOECuO1HAiH8f3W T15HYB+ilGpj2yH969+Ggw/sFzhPwEJQCCJvOk1/ESiL/XCp24eEsMRxYtwjMXC2 rdOCUOP1+4vXywytiraYNee4eNIae66x1Mg7+mCortQyyvXtt1VaOmlZHwk1gdgs P5kZjVwYzczNlxeQCkjaPtgOT13iqwo4+GUq1ezjSKtTXAZB4HgWYAaHKjqzOxRp STGaNwFyzF/+LkPLHwe9cgm1STGgX/LvyH/SI8hziqtJzkgTTOTxbDWh+GCtVJsR HRJdrLe2k5bEW0ygV/01ACDiOJLY3tikUhZi1wrjQ1THAbUsIGIBRCooL7/q8iUQ UsLCsOLBUI82oy3M/r0ZkLAZ3gC2aOmxPyp7AcGL17V90+2k90uZL99Ir8HJMtob FdEXztPh8x1lYhZoj1DJd1YXA/sxNG0n9CqhLJGcXkwf6L4V+uyoQlDoQrKjky9C Dvtd0cGrPaOEGoLj1ABvwFagmU1oDqkd4OeHx2bxZnpipBGLxQTAKwaBjp6+FFEk lOMPAzEU8hXVo5Bj/nNmxZmwraEzcV0WwFiLCLvOUUt5dFhZIns= =eD91 -----END PGP SIGNATURE----- Merge tag 'linux-cpupower-6.4-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/shuah/linux Pull cpupower utility fixes for 6.4-rc3 from Shuah Khan: "This cpupower fixes update for Linux 67.4-rc3 consists of: - a resource leak fix - fix drift in C0 percentage calculation due to System-wide TSC read.
