Re: Proposed Up/Down protocol description




- suggested_sia_head is a filesystem path so it should be some sort of
lowest common denominator of the PATH_MAX of the platforms that will be
running this (typically 1K)
- cert serial length(decimal(2^(8*20))) (RFC 3280 says 20 octets)
- msg_ref is length(decimal(2^64)) (or maybe length(decimal(2^128)))

These sound reasonable.

The remaining fields, sender, recipient, class name and the
resource_set_*, we could take one of two approaches:

- try to estimate what would be "sensible" maximums based on the
conceivable maximum number of entities involved. eg, sender, recipient,
and classname are 255 chars, resource_set_* are 4k

classname: ok
resource_set: this could be larger, sepacially if we did lots of RIR2RIR transfers. OTOH, I think the value of this field will be parsed and split into db records anyway - at least that's how I would do it.

- make the maximums stupidly large. eg, sender, recipient, and classname
can be 1K (or 4K, or....), resource_set_* are 8k (or 16k, or....)

WFM too. The point is not to let them grow to insane sizes as that could lead to failed processes DOS attacks.
