Affected Product(s):
BIG-IP LTM
Fixed In:
16.1.0
Opened: Aug 21, 2020 Severity: 4-Minor
This an improvement; there is no defect or known issue
This should have no impact on endpoints, but it will help to preserve future extensibility of the protocol.
This an improvement.
If you wish to disable this function, you can set the db variable quic.bit.grease to 'disable'. When disabled, BIG-IP will neither advertise the ability to accept values other than '1', nor will it send values other than '1'. It will reject packets that set it to '0'. The reasons to disable would be that (1) something in the path is dropping packets with the greased bit, or (2) future evaluation of the draft shows that this in some way introduces a security or performance impact.
BIG-IP now fully implements draft-thomson-quic-bit-grease-00, an optional extension that allows the second bit in each QUIC packet to be a random value instead of always '1', if the client requests it.
