             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.
