selftests/mm: add hugetlb_fault_after_madv to .gitignore

2023-11-15T23:30:09+00:00

commit 116d57303a05 ("selftests/mm: add a new test for madv and hugetlb")
added a new test case, but, it didn't add the binary name in
tools/testing/selftests/mm/.gitignore.

Add hugetlb_fault_after_madv to tools/testing/selftests/mm/.gitignore.

selftests/mm: restore number of hugepages

2023-11-15T23:30:08+00:00

The test mm `hugetlb_fault_after_madv` selftest needs one and only one
huge page to run, thus it sets `/proc/sys/vm/nr_hugepages` to 1.

The problem is that further tests require the previous number of hugepages
allocated in order to succeed.

Save the number of huge pages before changing it, and restore it once the
test finishes, so, further tests could run successfully.

selftests: mm: skip whole test instead of failure

2023-11-15T23:30:08+00:00

Some architectures don't support userfaultfd.  Skip running the whole test
on them instead of registering the failure.

selftests: mptcp: fix fastclose with csum failure

2023-11-15T04:10:21+00:00

Running the mp_join selftest manually with the following command line:

  ./mptcp_join.sh -z -C

leads to some failures:

  002 fastclose server test
  # ...
  rtx                                 [fail] got 1 MP_RST[s] TX expected 0
  # ...
  rstrx                               [fail] got 1 MP_RST[s] RX expected 0

The problem is really in the wrong expectations for the RST checks
implied by the csum validation. Note that the same check is repeated
explicitly in the same test-case, with the correct expectation and
pass successfully.

Address the issue explicitly setting the correct expectation for
the failing checks.

Add a few more simple cases to validate proper privileged vs unprivileged
loop detection behavior. conditional_loop2 is the one reported by Hao
Sun that triggered this set of fixes.
