Cloudfront: HTTP/2 compliance issue

QUESTION

Cloudfront: HTTP/2 compliance issue

Asked 2019-Nov-20 at 18:39

I've resorted to stackoverflow becase AWS doesn't provide technical support for free tiers.

Someone reported an issue using httpx, the ruby HTTP client library I maintain: https://gitlab.com/honeyryderchuck/httpx/issues/64

The report came after a recent upgrade to improve HTTP/2 spec compliance in the parser. Although the library now passes the h2spec, there seem to be legitimate issues requesting from cloudfront, due to an apparent part of the spec they don't seem to comply with: when a flow control window over 2 ** 31 - 1 is advertised, the sender must not allow it and return a flow control error.

Is it correct?

...

ANSWER

Answered 2019-Nov-19 at 00:30

You are correct that the flow control window cannot exceed 2^31-1, as indicated in the specification.

The initial flow control window is 65535, not 65536 as sent from Cloudfront, so the subsequent enlargement of the flow control window by 2147418112 yields 2^31 which is off-by-one too big for the flow control window.

Your client correctly sends a GO_AWAY with error FLOW_CONTROL_ERROR.
