Execution of command:
./tools/net/ynl/cli.py --spec Documentation/netlink/specs/dpll.yaml /
--subscribe "monitor" --sleep 10
fails with:
File "/repo/./tools/net/ynl/cli.py", line 109, in main
ynl.check_ntf()
File "/repo/tools/net/ynl/lib/ynl.py", line 924, in check_ntf
op = self.rsp_by_value[nl_msg.cmd()]
KeyError: 19
Parsing Generic Netlink notification messages performs lookup for op in
the message. The message was not yet decoded, and is not yet considered
GenlMsg, thus msg.cmd() returns Generic Netlink family id (19) instead of
proper notification command id (i.e.: DPLL_CMD_PIN_CHANGE_NTF=13).
Allow the op to be obtained within NetlinkProtocol.decode(..) itself if the
op was not passed to the decode function, thus allow parsing of Generic
Netlink notifications without causing the failure.

bind_wildcard is compiled but not run, bind_timewait is not compiled.
These two tests complete in a very short time, use the test harness
properly, and seem reasonable to enable.
The author of the tests confirmed via email that these were
intended to be run.
Enable these two tests.

The encoding of the pkey register differs on arm64, than on x86/ppc. On those
platforms, a bit in the register is used to disable permissions, for arm64, a
bit enabled in the register indicates that the permission is allowed.
This drops two asserts of the form:
assert(read_pkey_reg() <= orig_pkey_reg);
Because on arm64 this doesn't hold, due to the encoding.
The pkey must be reset to both access allow and write allow in the signal
handler. pkey_access_allow() works currently for PowerPC as the
PKEY_DISABLE_ACCESS and PKEY_DISABLE_WRITE have overlapping bits set.
Access to the uc_mcontext is abstracted, as arm64 has a different structure.

The test is supposed to be killed before the end, which will likely
cause "Connection reset by peer" errors. It is confusing, especially
because in case of real transfer errors, the test will not be marked as
failed. But that's OK, there are many other tests checking that.

Instead of displaying 'invert' when looking at some events like MP_FAIL,
MP_FASTCLOSE, MP_RESET, RM_ADDR, which is a bit vague because they are
not traditionnaly sent from one side, the host being checked is now
printed.
For the ADD_ADDR, only display the host when it is the client sending
it, which is more unusual.
Also before, the 'invert' message was printed after a few checks, but it
was not clear which ones exactly.

A few new MPJoinSynTx MIB counters have been added in a previous commit.
They are being validated here in mptcp_join.sh selftest, each time the
number of received MPJ are checked.
Most of the time, the number of sent SYN+MPJ is the same as the received
ones. But sometimes, there are more, because there are dropped, or there
are errors.
While at it, the "no MPC reuse with single endpoint" subtest has been
modified to force a bind() error.

have been received, each of them on one line.
More Join related tests are going to be checked soon, no need to add 5

issue, the errors will still be reported like before.

chk_join_nr() currently takes 9 positional parameters, 6 of them are
optional. It makes it hard to read:
chk_join_nr 1 1 1 1 0 1 1 0 4
Naming these vars helps to make it easier to read:
join_csum_ns1=1 join_csum_ns2=0 \
join_fail_nr=1 join_rst_nr=1 join_infi_nr=0 \
join_corrupted_pkts=4 \
chk_join_nr 1 1 1

The sctp selftest is very slow on debug kernels.
Its possible that the nf_queue listener program exits due to timeout
before first sctp packet is processed.
In this case socat hangs until script times out.
Fix this by removing the -t option where possible and kill the test
program once the file transfer/socat has exited.
-t sets SO_RCVTIMEO, its inteded for the 'ping' part of the selftest
where we want to make sure that packets get reinjected properly without
skipping a second queue request.
While at it, add a helper to compare the (binary) files instead of diff.
The 'diff' part was copied from a another sub-test that compares text.
Let helper dump file sizes on error so we can see the progress made.
Tested on an old 2010-ish box with a debug kernel and 100 iterations.
This is a followup to the earlier filesize reduction change.

The 32-bit arm build system will complain:
tools/perf/util/python.c:75:28: error: field ‘sample’ has incomplete type
75 | struct perf_sample sample;
However, arm64 build system doesn't complain this.
The root cause is arm64 define "HAVE_KVM_STAT_SUPPORT := 1" in
tools/perf/arch/arm64/Makefile, but arm arch doesn't define this.
This will lead to kvm-stat.h include other header files on arm64 build
system, especially "util/sample.h" for util/python.c.
This will try to directly include "util/sample.h" for "util/python.c" to
avoid such build issue on arm platform.

The spinlock and rwlock use a single-element per-cpu array to track
current locks due to performance reason. But this means the key is
always available and it cannot simply account lock stats in the array
because some of them are invalid.
In fact, the contention_end() program in the BPF invalidates the entry
by setting the 'lock' value to 0 instead of deleting the entry for the
hashmap. So it should skip entries with the lock value of 0 in the
account_end_timestamp().
Otherwise, it'd have spurious high contention on an idle machine:
$ sudo perf lock con -ab -Y spinlock sleep 3
contended total wait max wait avg wait type caller
8 4.72 s 1.84 s 590.46 ms spinlock rcu_core+0xc7

1 11.61 us 11.61 us 11.61 us spinlock rcu_core+0xc7
I don't believe it has contention on a spinlock longer than 1 second.
After this change, it only reports some small contentions.

Commit 3e0bf9fde2984469 ("perf pmu: Restore full PMU name wildcard

wildcard support provided by function perf_pmu__match(). The test works
with a wide range of supported combinations of PMU name matching but
omits the case that if the perf_pmu__match() cannot match the PMU name
to the wildcard, it tries to match its alias. However, this variable is
not set up, causing the test case to fail when run with subprocesses or
to segfault if run as a single process.

The __NR_mmap isn't found on armhf. The mmap() is commonly available
system call and its wrapper is present on all architectures. So it should
be used directly. It solves problem for armhf and doesn't create problem
for other architectures.
Remove sys_mmap() functions as they aren't doing anything else other than
calling mmap(). There is no need to set errno = 0 manually as glibc
always resets it.
For reference errors are as following:

The test case for SME vector length changes via sigreturn use a bit too
much cut'n'paste and only actually changed the SVE vector length in the
test itself. Andre's recent factoring out of the initialisation code caused
this to be exposed and the test to start failing. Fix the test to actually
cover the thing it's supposed to test.

Add a new arch_timer_edge_cases selftests that validates:
* timers above the max TVAL value
* timers in the past
* moving counters ahead and behind pending timers
* reprograming timers
* timers fired multiple times
* masking/unmasking using the timer control mask
These are intentionally unusual scenarios to stress compliance with
the arm architecture.

Someone reported on GitHub that the YNL NIPA test is failing
when run locally. The test builds the tools, and it hits:
netdev.c:82:9: warning: ignoring return value of ‘scanf’ declared with attribute ‘warn_unused_result’ [-Wunused-result]
82 | scanf("%d", &ifindex);
I can't repro this on my setups but error seems clear enough.

Charlie Jenkins <[email protected]> says:
There have been a couple of reports that using the hint address to
restrict the address returned by mmap hint address has caused issues in
applications. A different solution for restricting addresses returned by
mmap is necessary to avoid breakages.
[Palmer: This also just wasn't doing the right thing in the first place,
as it didn't handle the sv39 cases we were trying to deal with.]

This test extends "delete re-add signal" to validate the previous
commit: when the 'signal' endpoint linked to the initial subflow (ID 0)
is re-added multiple times, it will re-send the ADD_ADDR with id 0. The
client should still be able to re-create this subflow, even if the
add_addr_accepted limit has been reached as this special address is not
considered as a new address.
The 'Fixes' tag here below is the same as the one from the previous
commit: this patch here is not fixing anything wrong in the selftests,
but it validates the previous fix for an issue introduced by this commit
ID.

This test extends "delete and re-add" and "delete re-add signal" to
validate the previous commit: the number of MPTCP events are checked to
make sure there are no duplicated or unexpected ones.
A new helper has been introduced to easily check these events. The
missing events have been added to the lib.

This test extends "delete and re-add" to validate the previous commit:
when the endpoint linked to the initial subflow (ID 0) is re-added
multiple times, it was no longer being used, because the internal linked
counters are not decremented for this special endpoint: it is not an
additional endpoint.
Here, the "del/add id 0" steps are done 3 times to unsure this case is
validated.

The initial subflow has a special local ID: 0. It is specific per
connection.
When a global endpoint is deleted and re-added later, it can have a
different ID, but the kernel should still use the ID 0 if it corresponds
to the initial address.
This test validates this behaviour: the endpoint linked to the initial
subflow is removed, and re-added with a different ID.
Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
counter, as it will be seen as an additional subflow this time.

Removing the endpoint linked to the initial subflow should trigger a
RM_ADDR for the right ID, and the removal of the subflow. That's what is
now being verified in the "delete and re-add" test.
Note that removing the initial subflow will not decrement the 'subflows'
counters, which corresponds to the *additional* subflows. On the other
hand, when the same endpoint is re-added, it will increment this
