sctp: fix the data size calculation in sctp_data_size
sctp data size should be calculated by subtracting data chunk header's length from chunk_hdr->length, not just data header. Fixes: 668c9beb9020 ("sctp: implement assign_number for sctp_stream_interleave") Signed-off-by: Xin Long <lucien.xin@gmail.com> Acked-by: Marcelo Ricardo Leitner <marcelo.leitner@gmail.com> Signed-off-by: David S.
