Dave Watson cd00edc179 strparser: Fix sign of err codes ... strp_parser_err is called with a negative code everywhere, which then calls abort_parser with a negative code. strp_msg_timeout calls abort_parser directly with a positive code. Negate ETIMEDOUT to match signed-ness of other calls. The default abort_parser callback, strp_abort_strp, sets sk->sk_err to err. Also negate the error here so sk_err always holds a positive value, as the rest of the net code expects. Currently a negative sk_err can result in endless loops, or user code that thinks it actually sent/received err bytes. Found while testing net/tls_sw recv path.
