Subject: [bpf PATCH v4 0/4] sockmap/ktls fixes

Series of fixes for sockmap and ktls, see patches for descriptions.

v2: fix build issue for CONFIG_TLS_DEVICE and fixup couple comments
    from Jakub

v3: fix issue where release could call unhash resulting in a use after
    free. Now we detach the ulp pointer before calling into destroy
    or unhash. This way if we get a callback into unhash from destroy
    path there is no ulp to access. The fallout is we must pass the
    ctx into the functions rather than use the sk lookup in each
    routine. This is probably better anyways.

v4: move unhash routine to TLS_SW only, hardware offloads need to
    keep ctx around long enough to free in-flight context. We will
    need a follow up fix for this.

John Fastabend (4):
      bpf: tls, implement unhash to avoid transition out of ESTABLISHED
      bpf: sockmap, only stop/flush strp if it was enabled at some point
      bpf: sockmap remove duplicate queue free
      bpf: sockmap fix msg->sg.size account on ingress skb
