Follow-up Comment #4, bug #22110 (project lwip):
ACKing the data before its delivered to the application is fine. The problem
here is updating the available window while we're still buffering the data.
The change needed here - being able to find out if the layer above is
buffering data - is similar to the one needed to support shutdown and close
properly. (BUG #24830) While this bug is a minor problem, BUG #24830 is more
serious, and if I can fix that we might get the solution to this one for
free.
