Subject: [PATCH bpf-next 0/2] test_bpf: Add an skb_segment test for a linear head_frag=0 skb whose gso_size was mangled

Add a reproducer test that mimics the input skbs that lead to the BUG_ON
in skb_segment() which was fixed by commit 3dcbdb134f32 ("net: gso: Fix skb_segment splat when splitting gso_size mangled skb having linear-headed frag_list").

Shmulik Ladkani (2):
  test_bpf: Refactor test_skb_segment() to allow testing skb_segment()
    on numerous different skbs
  test_bpf: Introduce 'gso_linear_no_head_frag' skb_segment test
