bpf verifier is misconfigured
Summary: 0 PASSED, 0 SKIPPED, 1 FAILED
The bpf_sock_is_valid_access() is expecting src_ip4 can be narrowly
loaded (meaning load any 1 or 2 bytes of the src_ip4) by
marking info->ctx_field_size. However, this marked
ctx_field_size is not used. This patch fixes it.
Due to the recent refactoring in test_verifier,
this new test will be added to the bpf-next branch
(together with the bpf_tcp_sock patchset)
to avoid merge conflict.
