Most list head structs need not be given a name. In most cases the
name is given just in case one is going to use QTAILQ_LAST, QTAILQ_PREV
or reverse iteration, but this does not apply to lists of other kinds,
and even for QTAILQ in practice this is only rarely needed. In addition,
we will soon reimplement those macros completely so that they do not
need a name for the head struct. So clean up everything, not giving a

In usb_device_post_load, certain values of dev->setup_len or
dev->setup_index can cause -EINVAL to be returned. One example is when
setup_len exceeds 4096, the hard-coded value of sizeof(dev->data_buf).
This can happen through legitimate guest activity and will cause all
subsequent attempts to migrate the guest to fail in vmstate_load_state.
The values of these variables can be set by USB packets originating in
the guest. There are two ways in which they can be set: in
do_token_setup and in do_parameter in hw/usb/core.c.
It is easy to craft a USB packet in a guest that causes do_token_setup
to set setup_len to a value larger than 4096. When this has been done
once, all subsequent attempts to migrate the VM will fail in
usb_device_post_load until the VM is next power-cycled or a
smaller-sized USB packet is sent to the device.
Sample code for achieving this in a VM started with "-device usb-tablet"
running Linux with CONFIG_HIDRAW=y and HID_MAX_BUFFER_SIZE > 4096:
#include <sys/types.h>
#include <sys/stat.h>
#include <fcntl.h>
#include <unistd.h>
int main() {
char buf[4097];
int fd = open("/dev/hidraw0", O_RDWR|O_NONBLOCK);
buf[0] = 0x1;
write(fd, buf, 4097);
return 0;
}
When this code is run in the VM, qemu will output:
usb_generic_handle_packet: ctrl buffer too small (4097 > 4096)
A subsequent attempt to migrate the VM will fail and output the
following on the destination host:
qemu-kvm: error while loading state for instance 0x0 of device '0000:00:06.7/1/usb-ptr'
qemu-kvm: load of migration failed: Invalid argument
The idea behind checking the values of setup_len and setup_index before
they are used is correct, but doing it in usb_device_post_load feels
arbitrary, and will cause unnecessary migration failures. Indeed, none
of the commit messages for c60174e8, 9f8e9895 and 719ffe1f justify why
post_load is the right place to do these checks. They correctly point
out that the important thing to protect is the usb_packet_copy.
Instead, the right place to do the checks is in do_token_setup and
do_parameter. Indeed, there are already some checks here. We can examine
each of the disjuncts currently tested in usb_device_post_load to see
whether any need adding to do_token_setup or do_parameter to improve
safety there:
* dev->setup_index < 0
- This test is not needed because setup_index is explicitly set to
0 in do_token_setup and do_parameter.
* dev->setup_len < 0
- In both do_token_setup and do_parameter, the value of setup_len
is computed by (s->setup_buf[7] << 8) | s->setup_buf[6]. Since
s->setup_buf is a byte array and setup_len is an int32_t, it's
impossible for this arithmetic to set setup_len's top bit, so it can
never be negative.
* dev->setup_index > dev->setup_len
- Since setup_index is 0, this is equivalent to the previous test,
so is redundant.
* dev->setup_len > sizeof(dev->data_buf)
- This condition is already explicitly checked in both
do_token_setup and do_parameter.
Hence there is no need to bolster the existing checks in do_token_setup
or do_parameter, and we can safely remove these checks from
usb_device_post_load without reducing safety but allowing migrations to
proceed regardless of what USB packets have been generated by the guest.

The emulated_realize method was changed so that it jumps to a cleanup

Because qemu ignores symlinks, carrying out a successful symlink attack

The token field contains the (guest-filled) state of the qtd, which
indicates whenever the other fields are valid or not. So make sure
we read the token first, otherwise we may end up with an stale next
pointer:
(1) ehci reads next
(2) guest writes next
(3) guest writes token
(4) ehci reads token
(5) ehci operates with stale next.
Typical effect is that qemu doesn't notice that the guest appends new
qtds to the end of the queue. Looks like the usb device stopped
responding. Linux can recover from that, but leaves a message in the
kernel log that it did reset the usb device in question.

Fei Li pointed out that doing error_propagate() first doesn't work
well when @errp is &error_fatal or &error_abort: the error_prepend()
is never reached.
Since I doubt fixing the documentation will stop people from getting
it wrong, introduce error_propagate_prepend(), in the hope that it
lures people away from using its constituents in the wrong order.
Update the instructions in error.h accordingly.
Convert existing error_prepend() next to error_propagate to
error_propagate_prepend(). If any of these get reached with
&error_fatal or &error_abort, the error messages improve. I didn't

This is mandated by the ohci specification. It tells at 6.4.4 on page 104
that for transfer descriptors that are retired with an error the done
queue interrupt counter is cleared as if the interrupt delay field of the
descriptions were zero.
Before this change, error conditions were handled similarly to the
successful condition which is especially troublesome for control transfers.
Some drivers (e.g., the AmigaOS-one) as well as the example code in the
spec, set the setup stage with an interrupt delay of seven (which means no
interrupt). This is fine under normal conditions, because one usually
doesn't want to be notified about the completion of this stage. However, if
an error occurs in this stage, these drivers will not get notified with the
current implementation. The fix addresses this by following the spec more
closely. Also, otherwise, the ability to set interrupt delay to seven would
be useless.
Note that Linux drivers that I looked at don't seem to be affected as they
set six as the interrupt delay presumably for the reason that they won't
get notified otherwise.

Fetching qtd with the NULL address most likely makes no sense so from now
on, we handle it this case similarly as if the terminate (T) bit is not
set, which is already an exception as according to section 3.6 of the EHCI
spec there is no T bit defined for the current_qtd field.
The spec is a bit vague on how an EHCI driver should initialize these
fields: "The general operational model is that the host controller can
detect whether the overlay area contains a description of an active
transfer" (p. 49). QEMU primarily uses the QTD_TOKEN_ACTIVE bit of the
queue header to infer the activity state but there are other ways
conceivable.
This change allows QEMU to boot further into AmigaOS. The public available
version of the EHCI driver recycles queue heads in some rare conditions but
only clears the current_qtd field but not the status field. This works with
many available EHCI PCI cards but e.g., not with the Freescale USB
controller's found on the P5040. On the emulated EHCI controller of QEMU
the consequence is that some garbage was read in, which resulted in a
reset of the controller. This change fixes the problem.

The error handling policy was traditionally set with -drive, but with
-blockdev it is no longer possible to set frontend options. scsi-disk
(and other block devices) have long supported qdev properties to
configure the error handling policy, so let's add these options to
usb-storage as well and just forward them to the internal scsi-disk
instance.

The -drive option serial was deprecated in QEMU 2.10. It's time to
remove it.
Tests need to be updated to set the serial number with -global instead
of using the -drive option.

We banned use of certain g_assert_FOO() functions outside tests, and
made checkpatch.pl flag them (commit 6e9389563e). We neglected to
purge existing uses. Do that now.
