[RFC PATCH v1 0/3] Fix TCP short AF_UNSPEC handling

[Matthieu Buffet <matthieu@buffet.re>]

Hi Mickaël, Günther, Konstantin, Mikhail,

Here's a small fix for userland behaviour+error consistency in TCP, in
the edge case where userland uses an AF_UNSPEC address consisting of
just a bare sa_family_t.
First two commits fix/add test cases (which then fail), and third commit
patches current_check_access_socket() to make these tests pass. There's
more than one way to patch it, I just chose this because it should also
make it easier to merge UDP support (soon if this goes well).
Feedback welcome!

  selftests/landlock: Fix TCP bind(AF_UNSPEC) test case
  selftests/landlock: Add missing connect(minimal AF_UNSPEC) test
  landlock: Fix TCP handling of short AF_UNSPEC addresses
