BUG/MEDIUM: mux-h2: handle remaining read0 cases
Commit 3d4631fec ("BUG/MEDIUM: mux-h2: fix read0 handling on partial
frames") tried to address an issue introduced in commit aade4edc1 where
read0 wasn't properly handled in the middle of a frame. But the fix was
incomplete for two reasons:
- first, it would set H2_CF_RCVD_SHUT in h2_recv() after detecting
a read0 but the condition was guarded by h2_recv_allowed() which
explicitly excludes read0 ;
- second, h2_process would only call h2_process_demux() when there
were still data in the buffer, but closing after a short pause to
leave a buffer empty wouldn't be caught in this case.
This patch fixes this by properly taking care of the received shutdown
and by also waking up h2_process_demux() on an empty buffer if the demux
is not blocked.
Given the patches above were tagged for backporting to 2.0, this one
should be as well.
