Re: [TLS] [Technical Errata Reported] RFC5246 (4382)

["Corcoran, Laura S" <[e-mail]>]

It seems that Data is not a vector, but an array of vectors. Wouldn't that make a difference here?

I do not believe that this report is correct:

"A vector (single-dimensioned array) is a stream of homogeneous data elements.
The size of the vector may be specified at documentation time or left unspecified until runtime. In either case, the length declares the number of bytes, not the number of elements, in the vector."

	Type: Technical
	Reported by: Laura Corcoran <[e-mail]>
	
	Section: 4.3
	
	Original Text
	-------------
	In the following example, Datum is defined to be three consecutive
	   bytes that the protocol does not interpret, while Data is three
	   consecutive Datum, consuming a total of nine bytes.
	
	      opaque Datum[3];      /* three uninterpreted bytes */
	      Datum Data[9];        /* 3 consecutive 3 byte vectors */
	
	
	Corrected Text

	In the following example, Datum is defined to be three consecutive
	   bytes that the protocol does not interpret, while Data is three
	   consecutive Datum, consuming a total of nine bytes.
	
	      opaque Datum[3];      /* three uninterpreted bytes */
	      Datum Data[3];        /* 3 consecutive 3 byte vectors */
	
	
	Notes
	-----
	The 9 in "Datum Data[9]" should be a 3 because Datum is a data type that consumes 3 bytes, so as written the Data vector is 27 bytes long. To make it a 9 byte vector the 9 must change to a 3.
