[PATCH bpf 0/2] bpf, sockmap: fix copied_seq left behind when a stream parser is removed

[Sechang Lim]

A stream-parser sockmap socket can be removed with SK_PASS data still
parked on its ingress_msg queue. The copied_seq rollback for that data is
never repaid, leaving copied_seq behind sk_receive_queue, so the native
tcp_recvmsg() warns. Patch 1 settles copied_seq on removal. Patch 2 adds a
selftest.
