The virtio_scsi_bad_req() function is called when a guest sends a
request with missing or ill-sized headers. This generally happens
when the virtio_scsi_parse_req() function returns an error.
With this patch, virtio_scsi_bad_req() will mark the device as broken,
detach the request from the virtqueue and free it, instead of forcing
QEMU to exit.
In nearly all locations where virtio_scsi_bad_req() is called, the only
thing to do next is to return to the caller.
The virtio_scsi_handle_cmd_req_prepare() function is an exception though.
It is called in a loop by virtio_scsi_handle_cmd_vq() and passed requests
freshly popped from a cmd virtqueue; virtio_scsi_handle_cmd_req_prepare()
does some sanity checks on the request and returns a boolean flag to
indicate whether the request should be queued or not. In the latter case,
virtio_scsi_handle_cmd_req_prepare() has detected a non-fatal error and
sent a response back to the guest.
We have now a new condition to take into account: the device is broken
and should stop all processing.
The return value of virtio_scsi_handle_cmd_req_prepare() is hence changed
to an int. A return value of zero means that the request should be queued.
Other non-fatal error cases where the request shoudn't be queued return
a negative errno (values are vaguely inspired by the error condition, but
the only goal here is to discriminate the case we're interested in).
And finally, if virtio_scsi_bad_req() was called, -EINVAL is returned. In
this case, virtio_scsi_handle_cmd_vq() detaches and frees already queued
requests, instead of submitting them.

All these errors are caused by a buggy guest: QEMU should not exit.
With this patch, if virtio_blk_handle_request() detects a buggy request, it
marks the device as broken and returns an error to the caller so it takes
appropriate action.
In the case of virtio_blk_handle_vq(), we detach the request from the
virtqueue, free its allocated memory and stop popping new requests.
We don't need to bother about multireq since virtio_blk_handle_request()
errors out early and mrb.num_reqs == 0.
In the case of virtio_blk_dma_restart_bh(), we need to detach and free all
queued requests as well.

A broken guest may send a request without providing buffers for the reply
or for the request itself, and virtqueue_pop() will return an element with
either in_num == 0 or out_num == 0.
All 9P requests are expected to start with the following 7-byte header:
uint32_t size_le;
uint8_t id;
uint16_t tag_le;
If iov_to_buf() fails to return these 7 bytes, then something is wrong in
the guest.
In both cases, it is wrong to crash QEMU, since the root cause lies in the
guest.
This patch hence does the following:
- keep the check of in_num since pdu_complete() assumes it has enough
space to store the reply and we will send something broken to the guest
- let iov_to_buf() handle out_num == 0, since it will return 0 just like
if the guest had provided an zero-sized buffer.
- call virtio_error() to inform the guest that the device is now broken,
instead of aborting
- detach the request from the virtqueue and free it

Ports enter a "throttled" state when writing to the chardev would block.
The current output VirtQueueElement is kept around until the chardev
becomes writable again.
There are several places in the virtio-serial lifecycle where the
VirtQueueElement should be thrown away. For example, if the virtio
device is reset then virtqueue elements are no longer valid.
This patch adds the discard_throttle_data() function to unmap the
scatter-gather list and decrement vq->inuse. This ensures that the
VirtQueueElement is freed properly.

During device reset or similar situations a VirtQueueElement needs to be

Extract a new function to do this.
Later patches add virtio_detach_element() calls to existing device so
that scatter-gather lists are unmapped and vq->inuse goes back to zero
during device reset. Currently some devices don't bother and simply
call g_free(elem) which is not a clean way to throw away a
VirtQueueElement.

While processing isochronous transfer descriptors(iTD), if the page
select(PG) field value is out of bands it will return. In this
situation the ehci's sg list is not freed thus leading to a memory
leak issue. This patch avoid this.

hw/intc/sh_intc.c and hw/timer/sh_timer.c seem to belong to
the R2D machine, as far as I can see.
And concerning the Shix machine, it does not make much sense
to have a "M:" entry here and the "S:" set to "Orphan". So
I'd like to suggest to use "Odd Fixes" here instead.

The get_maintainer.pl script currently thinks that the win32
related files in the util and include folders are currently
unmaintained. Thus let's add some additional wildcards to
match these files.
