----------------------------------
Summary: HTTP/2 packet corruption introduced by TS-4717 fix
Key: TS-4766
URL: https://issues.apache.org/jira/browse/TS-4766
Project: Traffic Server
Issue Type: Bug
Components: HTTP/2
Reporter: Susan Hinrichs
We observed problems with large uploads over HTTP/2 via Firefox. Tracked it
down to ATS sending a GOAWAY frame early because the frame appeared to be
corrupted. The problem was introduced in the restructuring in TS-4717 to get
rid of the unbounded recursion. The logic will return with one of two handlers
set. One to deal with the case of starting to read a fresh frame and another
to deal with the case of finishing reading a partially read frame. There is a
path where we finish reading a frame but don't reset the handler to the new
frame case. When the next data arrives the wrong handler starts reading it
resulting in ATS thinking it has received a malformed frame.
