The xarray.c file contains the only call to radix_tree_node_rcu_free(),
and it comes with its own extern declaration for it. This means the
function definition causes a missing-prototype warning:
lib/radix-tree.c:288:6: error: no previous prototype for 'radix_tree_node_rcu_free' [-Werror=missing-prototypes]
Instead, move the declaration for this function to a new header that can
be included by both, and do the same for the radix_tree_node_cachep
variable that has the same underlying problem but does not cause a warning
with gcc.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the new listener events linked to the path-manager
introduced by commit f8c9dfbd875b ("mptcp: add pm listener events").
It is possible to look for "mptcp_event_pm_listener" in kallsyms to know
in advance if the kernel supports this feature and skip these sub-tests
if the feature is not supported.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the MPTCP Userspace PM introduced by commit 4638de5aefe5
("mptcp: handle local addrs announced by userspace PMs").
We can skip all these tests if the feature is not supported simply by
looking for the MPTCP pm_type's sysctl knob.

One of them is the getsockopt(SOL_MPTCP) to get info about the MPTCP
connections introduced by commit 55c42fa7fa33 ("mptcp: add MPTCP_INFO

We cannot guess in advance which sizes the kernel will returned: older
kernel can returned smaller sizes, e.g. recently the tcp_info structure
has been modified in commit 71fc704768f6 ("tcp: add rcv_wnd and
plb_rehash to TCP_INFO") where a new field has been added.
The userspace can also expect a smaller size if it is compiled with old
uAPI kernel headers.
So for these sizes, we can only check if they are above a certain
threshold, 0 for the moment. We can also only compared sizes with the
ones set by the kernel.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the fullmesh flag that can be given to the MPTCP
in-kernel path-manager and introduced in commit 2843ff6f36db ("mptcp:
remote addresses fullmesh").
If the flag is not visible in the dump after having set it, we don't
check the content. Note that if we expect to have this feature and
SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var is set to 1, we always
check the content to avoid regressions.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the checks of the default limits returned by the MPTCP
in-kernel path-manager. The default values have been modified by commit
72bcbc46a5c3 ("mptcp: increase default max additional subflows to 2").
Instead of comparing with hardcoded values, we can get the default one
and compare with them.
Note that if we expect to have the latest version, we continue to check
the hardcoded values to avoid unexpected behaviour changes.

Selftests are supposed to run on any kernels, including the old ones not
supporting all MPTCP features.
One of them is the reporting of the MPTCP sockets being used, introduced
by commit c558246ee73e ("mptcp: add statistics for mptcp socket in use").
Similar to the parent commit, it looks like there is no good pre-check
to do here, i.e. dedicated function available in kallsyms. Instead, we
try to get info and if nothing is returned, the test is marked as
skipped.

It looks like there is no good pre-check to do here, i.e. dedicated

is returned, the test is marked as skipped.
That's not ideal because something could be wrong with the feature and
instead of reporting an error, the test could be marked as skipped. If
we know in advanced that the feature is supposed to be supported, the
tester can set SELFTESTS_MPTCP_LIB_EXPECT_ALL_FEATURES env var to 1: in
this case the test will report an error instead of marking the test as
skipped if nothing is returned.

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.

The canonical location for the tracefs filesystem is at /sys/kernel/tracing.
But, from Documentation/trace/ftrace.rst:
Before 4.1, all ftrace tracing control files were within the debugfs
file system, which is typically located at /sys/kernel/debug/tracing.
For backward compatibility, when mounting the debugfs file system,
the tracefs file system will be automatically mounted at:
/sys/kernel/debug/tracing
A few spots in tools/virtio still refer to this older debugfs
path, so let's update them to avoid confusion.

In net/netlink/af_netlink.c, function netlink_getsockopt(), for NETLINK_LIST_MEMBERSHIPS,
nlk->ngroups equals to 36. Before Commit f4e4534850a9, the optlen is calculated as
ALIGN(nlk->ngroups / 8, sizeof(u32)) = 4
After that commit, the optlen is
ALIGN(BITS_TO_BYTES(nlk->ngroups), sizeof(u32)) = 8
Fix the test by setting the expected optlen to be 8.

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.

This patch is linked to the previous commit ("mptcp: only send RM_ADDR in
nl_cmd_remove").
To align with what is done by the in-kernel PM, update userspace pm addr
selftests, by sending a remove_subflows command together after the
remove_addrs command.

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.

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.

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.

Pull tracing fixes from Steven Rostedt:
"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"
