Subject: [PATCH net-next 0/8] Misc BPF updates

This set contains a couple of misc updates: stack usage reduction
for perf_sample_data in tracing progs, reduction of stale data in
verifier on register state transitions that I still had in my queue
and few selftest improvements as well as bpf_set_hash() helper for
tc programs.

Thanks!

Daniel Borkmann (8):
  bpf: avoid excessive stack usage for perf_sample_data
  bpf: don't check spilled reg state for non-STACK_SPILLed type slots
  bpf: reset id on CONST_IMM transition
  bpf: reset id on spilled regs in clear_all_pkt_pointers
  bpf, tests: add a test for htab lookup + update traversal
  bpf, tests: set rlimit also for test_align, so it doesn't fail
  bpf: remove cg_skb_func_proto and use sk_filter_func_proto directly
  bpf: add bpf_set_hash helper for tc progs
