[bpf,0/4] bpf, sockmap: fixes stress testing and regression

Message

Attached are 4 patches that fix issues we found by either stress testing
or updating our CI to LTS kernels. We nearly have CI running on BPF tree
now so hopefully future regressions will be caught much earlier.

Thanks to Jussi for all the hard work tracking down issues and getting
stress testing/CI running.

First two patches are issues discovered by Jussi after writing a stess
testing tool.

The last two fix an issue noticed while reviewing patches and xlated
code paths also discovered by Jussi.


John Fastabend (3):
  bpf, sockmap: Remove unhash handler for BPF sockmap usage
  bpf, sockmap: Fix race in ingress receive verdict with redirect to
    self
  bpf: sockmap, strparser, and tls are reusing qdisc_skb_cb and
    colliding

Jussi Maki (1):
  bpf: sk skb data_end stomps register when src_reg = dst_reg
