This patch set adds support for narrow loads with offset > 0 to BPF
verifier.

Patch 1 provides more details and is the main patch in the set.
Patches 2 and 3 add new test cases to test_verifier and test_sock_addr
selftests.


Andrey Ignatov (3):
  bpf: Allow narrow loads with offset > 0
  selftests/bpf: Test narrow loads with off > 0 in test_verifier
  selftests/bpf: Test narrow loads with off > 0 for bpf_sock_addr
