  selftests/bpf: Test bpf_skb_change_tail() in TC ingress (2024-12-20 23:13:31 +0100)

----------------------------------------------------------------
BPF fixes:

- Fix inlining of bpf_get_smp_processor_id helper for !CONFIG_SMP
  systems (Andrea Righi)

- Fix BPF USDT selftests helper code to use asm constraint "m"
  for LoongArch (Tiezhu Yang)

- Fix BPF selftest compilation error in get_uprobe_offset when
  PROCMAP_QUERY is not defined (Jerome Marchand)

- Fix BPF bpf_skb_change_tail helper when used in context of
  BPF sockmap to handle negative skb header offsets (Cong Wang)

- Several fixes to BPF sockmap code, among others, in the area
  of socket buffer accounting (Levi Zim, Zijian Zhang, Cong Wang)
