Hi David,

The following pull-request contains BPF updates for your *net* tree.

We've added 12 non-merge commits during the last 9 day(s) which contain
a total of 13 files changed, 95 insertions(+), 43 deletions(-).

The main changes are:

1) Fix refcount leak for TCP time wait and request sockets for socket lookup
   related BPF helpers, from Lorenz Bauer.

2) Fix wrong verification of ARSH instruction under ALU32, from Daniel Borkmann.

3) Batch of several sockmap and related TLS fixes found while operating
   more complex BPF programs with Cilium and OpenSSL, from John Fastabend.

4) Fix sockmap to read psock's ingress_msg queue before regular sk_receive_queue()
   to avoid purging data upon teardown, from Lingpeng Chen.

5) Fix printing incorrect pointer in bpftool's btf_dump_ptr() in order to properly
   dump a BPF map's value with BTF, from Martin KaFai Lau.

Daniel Borkmann (2):
      bpf: Fix incorrect verifier simulation of ARSH under ALU32
      Merge branch 'bpf-sockmap-tls-fixes'

John Fastabend (8):
      bpf: Sockmap/tls, during free we may call tcp_bpf_unhash() in loop
      bpf: Sockmap, ensure sock lock held during tear down
      bpf: Sockmap/tls, push write_space updates through ulp updates
      bpf: Sockmap, skmsg helper overestimates push, pull, and pop bounds
      bpf: Sockmap/tls, msg_push_data may leave end mark in place
      bpf: Sockmap/tls, tls_sw can create a plaintext buf > encrypt buf
      bpf: Sockmap/tls, skmsg can have wrapped skmsg that needs extra chaining
      bpf: Sockmap/tls, fix pop data with SK_DROP return code

Lingpeng Chen (1):
      bpf/sockmap: Read psock ingress_msg before sk_receive_queue
