openat is useful to avoid needing to construct relative paths, so expose

The open_tuntap helper function uses open() to get a file descriptor for
/dev/net/tun.
The open(2) manpage writes this about its return value:
On success, open(), openat(), and creat() return the new file
descriptor (a nonnegative integer). On error, -1 is returned and
errno is set to indicate the error.
This means that the fd > 0 assertion in the open_tuntap helper is
incorrect and should rather check for fd >= 0.
When running the BPF selftests locally, this incorrect assertion was not
an issue, but the BPF kernel-patches CI failed because of this:
open_tuntap:FAIL:open(/dev/net/tun) unexpected open(/dev/net/tun):
actual 0 <= expected 0

Add a selftest that creates a tap device, attaches XDP and TC programs,
writes a packet with a test payload into the tap device and checks the
test result. This test ensures that the XDP metadata support in the tun
driver is enabled and that the metadata size is correctly passed to the
skb.
See the previous commit ("selftests/bpf: refactor xdp_context_functional
test and bpf program") for details about the test design.
The test runs in its own network namespace. This provides some extra
safety against conflicting interface names.

The existing XDP metadata test works by creating a veth pair and
attaching XDP & TC programs that drop the packet when the condition of
the test isn't fulfilled. The test then pings through the veth pair and
succeeds when the ping comes through.
While this test works great for a veth pair, it is hard to replicate for
tap devices to test the XDP metadata support of them. A similar test for
the tun driver would either involve logic to reply to the ping request,
or would have to capture the packet to check if it was dropped or not.
To make the testing of other drivers easier while still maximizing code
reuse, this commit refactors the existing xdp_context_functional test to
use a test_result map. Instead of conditionally passing or dropping the
packet, the TC program is changed to copy the received metadata into the
value of that single-entry array map. Tests can then verify that the map
value matches the expectation.
This testing logic is easy to adapt to other network drivers as the only
remaining requirement is that there is some way to send a custom
Ethernet packet through it that triggers the XDP & TC programs.
The Ethernet header of that custom packet is all-zero, because it is not
required to be valid for the test to work. The zero ethertype also helps
to filter out packets that are not related to the test and would
otherwise interfere with it.
The payload of the Ethernet packet is used as the test data that is
expected to be passed as metadata from the XDP to the TC program and
written to the map. It has a fixed size of 32 bytes which is a
reasonable size that should be supported by both drivers. Additional
packet headers are not necessary for the test and were therefore skipped
to keep the testing code short.
This new testing methodology no longer requires the veth interfaces to
have IP addresses assigned, therefore these were removed.

To test the XDP metadata functionality of the tun driver, it's necessary
to create a new tap device first. A helper function for this already
exists in lwt_helpers.h. Move it to the common network helpers header,
so it can be reused in other tests.

with min/max boundaries
damon_nr_regions.py starts DAMON, periodically collect number of regions
in snapshots, and see if it is in the requested range. The check code
assumes the numbers are sorted on the collection list, but there is no
such guarantee. Hence this can result in false positive test success.
Sort the list before doing the check.

100ms
damon_nr_regions.py updates max_nr_regions to a number smaller than
expected number of real regions and confirms DAMON respect the harsh
limit. To give time for DAMON to make changes for the regions, 3
aggregation intervals (300 milliseconds) are given.
The internal mechanism works with not only the max_nr_regions, but also
sz_limit, though. It avoids merging region if that casn make region of
size larger than sz_limit. In the test, sz_limit is set too small to
achive the new max_nr_regions, unless it is updated for the new
min_nr_regions. But the update is done only once per operations set
update interval, which is one second by default.
Hence, the test randomly incurs false positive failures. Fix it by
setting the ops interval same to aggregation interval, to make sure
sz_limit is updated by the time of the check.

Patch series "selftests/damon: three fixes for false results".
Fix three DAMON selftest bugs that cause two and one false positive
failures and successes.
This patch (of 3):
damos_quota.py assumes the quota will always exceeded. But whether quota
will be exceeded or not depend on the monitoring results. Actually the
monitored workload has chaning access pattern and hence sometimes the
quota may not really be exceeded. As a result, false positive test
failures happen. Expect how much time the quota will be exceeded by
checking the monitoring results, and use it instead of the naive
assumption.

further reduced
damos_quota_goal.py selftest see if DAMOS quota goals tuning feature
increases or reduces the effective size quota for given score as expected.
The tuning feature sets the minimum quota size as one byte, so if the
effective size quota is already one, we cannot expect it further be
reduced. However the test is not aware of the edge case, and fails since
it shown no expected change of the effective quota. Handle the case by
updating the failure logic for no change to see if it was the case, and
simply skips to next test input.

This reverts commit a5c6bc590094a1a73cf6fa3f505e1945d2bf2461.
The general approach described in commit e076eaca5906 ("selftests: break
the dependency upon local header files") was taken one step too far here:
it should not have been extended to include the syscall numbers. This is
because doing so would require per-arch support in tools/include/uapi, and
no such support exists.
This revert fixes two separate reports of test failures, from Dave
Hansen[1], and Li Wang[2]. An excerpt of Dave's report:
Before this commit (a5c6bc590094a1a73cf6fa3f505e1945d2bf2461) things are

The PMU test commandline option takes an argument to disable a
certain test. The initial assumption behind this was a common use case
is just to run all the test most of the time. However, running a single
test seems more useful instead. Especially, the overflow test has been
helpful to validate PMU virtualizaiton interrupt changes.
Switching the command line option to run a single test instead
of disabling a single test also allows to provide additional
test specific arguments to the test. The default without any options
remains unchanged which continues to run all the tests.

There is no need to start the counter in the overflow handler as we
intend to trigger precise number of LCOFI interrupts through these
tests. The overflow irq handler has already stopped the counter. As
a result, the stop call from the test function may return already
stopped error which is fine as well.

Add extra parameters for rcutorture module. One is the "nfakewriters"
which is set -1. There will be created number of test-kthreads which
correspond to number of CPUs in a test system. Those threads randomly
invoke synchronize_rcu() call.
Apart of that "rcu_normal" is set to 1, because it is specifically for
a normal synchronize_rcu() testing, also a newly added parameter which
is "rcu_normal_wake_from_gp" is set to 1 also. That prevents interaction

Commit 14be4e6f3522 ("selftests: vDSO: fix ELF hash table entry size for s390x")
changed the type of the ELF hash table entries to 64bit on s390x.
However the *GNU* hash tables entries are always 32bit.
The "bucket" pointer is shared between both hash algorithms.
On s390, this caused the GNU hash algorithm to access its 32-bit entries as if they
were 64-bit, triggering compiler warnings (assignment between "Elf64_Xword *" and
"Elf64_Word *") and runtime crashes.
Introduce a new dedicated "gnu_bucket" pointer which is used by the GNU hash.

Allocating a domain with a fault ID indicates that the domain is faultable.
However, there is a gap for the nested parent domain to support PRI. Some
hardware lacks the capability to distinguish whether PRI occurs at stage 1
or stage 2. This limitation may require software-based page table walking
to resolve. Since no in-tree IOMMU driver currently supports this
functionality, it is disallowed. For more details, refer to the related
discussion at [1].
