Subject: [PATCH bpf-next v2 0/2] add hwtstamp to __sk_buff

This patch set adds hardware timestamps to __sk_buff. The first patch
implements feature, the second one adds a selftest.

v1 -> v2:

* Fixed bpf_skb_is_valid_access() to provide correct access to field
* Added explicit test to deny access to padding area
* Added verifier selftest to check for denied access to padding area

Vadim Fedorenko (2):
  bpf: add hardware timestamp field to __sk_buff
  selftests/bpf: test new __sk_buff field hwtstamp
