RE: iSCSI: Decimal encoding - why 64 bits ?

["THALER,PAT (A-Roseville,ex1)" <pat_thaler@agilent.com>]

Mark,

What about 40-bit to 56-bit decimal encoded binary values? They are allowed.

4.1
binary-value includes regular-binary-value and large-binary-value.
regular-binary-value is for strings less than 64 bits and allows decimal encoding. (It says less than 64 and decimal encoded binary strings are always in bytes so the largest decimal encoded binary would be 56 bits.)

10.4 SRP: N,g,s,A,B,M and H(A | M | K) are binary-values
10.5 CHAP: C and R are binary-values

10.2 and 10.3 use large-binary-value instead of binary-value and I can't find any other use of binary-value.

Normally, the values defined as binary-values for SRP and CHAP would be 64 bits or longer anyway, but someone could send short keys and encode them in decimal according to the current draft. This should be eliminated. 

Regards,
Pat

For what it's worth, none of the numeric values for iSCSI that
can be retrieved or set via the MIB require more than 32 bits
(other than counters, but I doubt we would ever send a counter
during negotiation :-).  The allowable ranges just didn't need
more than that.

Anyway, I haven't seen a need to provide support for 64-bit
values in our implementation yet, since none of the numeric
keys can have values that high.
