In some cases, qemu_chr_fe_read_all() on HUP event doesn't raise CHR_EVENT_CLOSED because the read/recv function returns -1 on disconnected peers (for example with tch_chr_recv, an ECONNRESET errno overwritten as EIO). It is simpler to explicitely disconnect on HUP, rising CHR_EVENT_CLOSED if it wasn't disconnected already. Signed-off-by: Marc-André Lureau <marcandre.lureau@redhat.com> Reviewed-by: Michael S.
