It looks like it does the wrong thing when the option space increases, which would have made hdr_delta negative if it were of a signed type. I think therefore that sk_conn->icsk_ext_hdr_len needs to be adjusted in both directions, just just when the option area length shrinks. -- To unsubscribe from this list: send the line "unsubscribe netdev" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
