bpf: support input __sk_buff context in BPF_PROG_TEST_RUN
...
Add new set of arguments to bpf_attr for BPF_PROG_TEST_RUN:
* ctx_in/ctx_size_in - input context
* ctx_out/ctx_size_out - output context
The intended use case is to pass some meta data to the test runs that
operate on skb (this has being brought up on recent LPC).
For programs that use bpf_prog_test_run_skb, support __sk_buff input and
output. Initially, from input __sk_buff, copy _only_ cb and priority into
skb, all other non-zero fields are prohibited (with EINVAL).
If the user has set ctx_out/ctx_size_out, copy the potentially modified
__sk_buff back to the userspace.
We require all fields of input __sk_buff except the ones we explicitly
support to be set to zero. The expectation is that in the future we might
add support for more fields and we want to fail explicitly if the user
runs the program on the kernel where we don't yet support them.
The API is intentionally vague (i.e. we don't explicitly add __sk_buff
to bpf_attr, but ctx_in) to potentially let other test_run types use
this interface in the future (this can be xdp_md for xdp types for
example).
v4:
* don't copy more than allowed in bpf_ctx_init [Martin]
v3:
* handle case where ctx_in is NULL, but ctx_out is not [Martin]
* convert size==0 checks to ptr==NULL checks and add some extra ptr
checks [Martin]
v2:
* Addressed comments from Martin Lau
