Xen devel - Sep 2006 - [PATCH] qemu-dm drops into infinite loop

Hi,

I encountered the problem that qemu-dm hangs up.
After some investigation, I found qemu-dm drops into infinite loop
in function vnc_client_read() of tools/ioemu/vnc.c.

    while (vs->read_handler && vs->input.offset >=
vs->read_handler_expect) {
	size_t len = vs->read_handler_expect;
	int ret;

	ret = vs->read_handler(vs, vs->input.buffer, len);
	...
	if (!ret) {
	    ...
	} else
	    vs->read_handler_expect = ret;
    }

Attached patch prevents qemu-dm from causing the infinite loop.

Thanks
Kouya
