[PATCH V2 net-next 0/6] test_bpf improvements

Hello,

Please find below the patch series with my latest changes to test_bpf.

The first patch checks for unexpected NULL generated skbs before
running the filter.

The second patch adds the possibility for tests to generate fragmented
skbs.

The third patch tests LD_ABS and LD_IND on fragmented skbs.

The fourth patch adds the possibility to restrict the tests being run
by specifying the name/id/range of the test(s) to run via module
parameters.

The fifth patch tests LD_ABS and LD_IND on non fragmented skbs with
various sizes and alignments.

The sixth and final patch checks that the interpreter or JIT correctly
resets A and X to 0.

This serie is against today's net-next tree.

Changes in V2:

* move declaration of 'ptr' in if() block in patch 2/6.

* fix various typos in patch 4/6

* rework default init of test_range array and cleanup exclude_test()
  return condition in patch 4/6.

Regards,

Nicolas Schichan (6):
  test_bpf: avoid oopsing the kernel when generate_test_data() fails.
  test_bpf: allow tests to specify an skb fragment.
  test_bpf: test LD_ABS and LD_IND instructions on fragmented skbs.
  test_bpf: allow running of a single test specified as a module
    parameter.
  test_bpf: add more tests for LD_ABS and LD_IND.
  test_bpf: add tests checking that JIT/interpreter sets A and X to 0.
