bpf/selftests: add a few helpers for bpftool testing
0ede6a5 
In order to integrate some bpftool tests into test_progs, define a few
specific helpers that allow to execute bpftool commands, while possibly
retrieving the command output. Those helpers most notably set the
path to the bpftool binary under test. This version checks different
possible paths relative to the directories where the different
test_progs runners are executed, as we want to make sure not to
accidentally use a bootstrap version of the binary.

Changes in v2:
- Drop the new runner from commit, keep only the new bpftool-specific
  helpers
- replace hardcoded path with a detected (and cached) path

selftests/bpf: convert test_bpftool_metadata.sh into test_progs frame…
fc7ad5b 
…work

The test_bpftool_metadata.sh script validates that bpftool properly
returns in its ouptput any metadata generated by bpf programs through
some .rodata sections.

Port this test to the test_progs framework so that it can be executed
automatically in CI. The new test, similarly to the former script,
checks that valid data appears both for textual output and json output,
as well as for both data not used at all and used data. For the json
check part, the expected json string is hardcoded to avoid bringing a
new external dependency (eg: a json deserializer) for test_progs.
As the test is now converted into test_progs, remove the former script.

The newly converted test brings two new subtests:

  kernel-patches#37/1    bpftool_metadata/metadata_unused:OK
  kernel-patches#37/2    bpftool_metadata/metadata_used:OK
  kernel-patches#37      bpftool_metadata:OK
  Summary: 1/2 PASSED, 0 SKIPPED, 0 FAILED

Changes in v2:
- move the new test in prog_tests directory
- use power of 2 for bpftool output buffer size
- check snprintf return when building commands
- target program by pin path rather than prog name
- remove a few blank lines

selftests/bpf: convert test_bpftool_map_access.sh into test_progs fra…
4c979fc 
…mework

The test_bpftool_map.sh script tests that maps read/write accesses
are being properly allowed/refused by the kernel depending on a specific
fmod_ret program being attached on security_bpf_map function.

Rewrite this test to integrate it in the test_progs. The
new test spawns a few subtests:

  kernel-patches#36/1    bpftool_maps_access/unprotected_unpinned:OK
  kernel-patches#36/2    bpftool_maps_access/unprotected_pinned:OK
  kernel-patches#36/3    bpftool_maps_access/protected_unpinned:OK
  kernel-patches#36/4    bpftool_maps_access/protected_pinned:OK
  kernel-patches#36/5    bpftool_maps_access/nested_maps:OK
  kernel-patches#36/6    bpftool_maps_access/btf_list:OK
  kernel-patches#36      bpftool_maps_access:OK
  Summary: 1/6 PASSED, 0 SKIPPED, 0 FAILED
