There is some ambiguity in the RFC as to whether the ADD_ADDR HMAC is the rightmost 64 bits of the entire hash or of the leftmost 160 bits of the hash. The intention, as clarified with the author of the RFC, is the entire hash. This change returns the entire hash from mptcp_crypto_hmac_sha (instead of only the first 160 bits), and moves any truncation/selection operation on the hash to the caller. Fixes: 12555a2d ("mptcp: use rightmost 64 bits in ADD_ADDR HMAC") Reviewed-by:
