process_attestation: Validate epoch before using it
2020-07-24 08:04:06 -06:00
Jacek Sieka 6f7652d330
process_attestation: Validate epoch before using it
`data.target.epoch` is used to count the active validator set.

Because `get_committee_count_per_slot` is extremely inefficient the way
the spec is written, clients cache it, or the underlying active
validator set.

Performing the checks in the given order leads to a (very unlikely)
security issue where the a cold and above all, distant value may get
used which may be costly - reordering the checks brings the value into a
more reasonable range before using it.

Jacek Sieka 56309342c0
Use `Bytes32` for `error_message`
`ErrorMessage.error_message` is a leftover from an older version of SSZ
that was able to encode unbounded lists. This is no longer the case -
all collection types now have a fixed upper bound on length.

In general, the `error_message`, just like the `graffitti` field, should
not be interpreted in any particular way except for debugging and vanity
- as such, using the same type, a `Bytes32`, seems reasonable.

An alternative would be `List[byte, 256]` which maybe could be
"reasonably backwards compatible" with whatever clients are are doing
now - depending on how they are dealing with this field type that no
longer exists in the SSZ spec :) It would however be the only place
where `List[uintN, N]` is used in the current spec.

As an exercise, this could be considered a security issue since it's
essentially unbounded and undefined behaviour.

require blocks to be ordered consecutively in block range request
Per the spec, if I request range 5-10, it is permissible for a client to
answer with block 7, 9 - even if the blocks 5, 6 and 8 exist.

Because blocks 7 and 9 cannot be validated as they arrive in such a
request, it seems better to close this gap - this update adds the spec
language that forbids well-behaving clients from answering this way.
