If an (emulated) usb-device tries to write more data to a packet then
its iov len, this will trigger an assert in usb_packet_copy(), and if
a driver somehow circumvents that check and writes more data to the
iov then there is space, we have a much bigger problem then not correctly
reporting babble to the guest.
In practice babble will only happen with (real) redirected devices, and there
both the usb-host os and the qemu usb-device code already check for it.

This can happen with usb-redir live-migration when the packet gets re-queued
after the migration and the original queuing from the migration source side

This reverts commit 9bc3a3a216e2689bfcdd36c3e079333bbdbf3ba0, which got
added to fix an issue where the real, underlying cause was not stopping
the ep queue on an error.
Now that the underlying cause is fixed by the "usb: Halt ep queue and
cancel pending packets on a packet error" patch, the "don't flush" fix
is no longer needed.
Not only is it not needed, it causes us to see cancellations (unlinks)
done by the Linux EHCI driver too late, which in combination with the new
usb-core packet-id generation where qtd addresses are used as ids, causes
duplicate ids for in flight packets.

Otherwise we'll see the packet free twice in the trace log even though
it actually happens only once.

make qemu_queue_{cancel,reset} return the number of packets released,
so the caller can figure whenever there have been active packets even
though there shouldn't have been any. Add tracepoint to log this.

Currently each time we try to execute a NAK-ed packet we redo
ehci_init_transfer, and usb_packet_map, re-allocing (without freeing) the
sg list every time.
This patch fixes this, it does this by introducing another async state, so
that we also properly cleanup a NAK-ed packet on cancel.

USB_RET_PROCERR can be triggered by the guest (by for example requesting more
then BUFFSIZE bytes), so don't assert on it.

Since my previous comment said "Should never happen", I tried changing the
next line to an assert(0), which did not go well, which as the new comments
explains is logical if you think about it for a moment.

USB_RET_NAK is not a valid response for async handled packets (and will
trigger an assert as such).
Also drop the warning when receiving a status of cancelled for packets not
cancelled by qemu itself, this can happen when a device gets unredirected
by the usbredir-host while transfers are pending.

There is no need for this, and doing so means that a backend trying to
write immediately after an open event will see qemu_chr_be_can_write
returning 0, which not all backends handle well as there is no wakeup
mechanism to detect when the frontend does become writable.

The shadow copy only serves as an extra check (besides the packet-id) to
ensure the packet we get back is a reply to the packet we think it is.
This check has never triggered in all the time usb-redir is in use now,
and since the verified data in the returned packet-header is not used
otherwise, removing the check does not open any possibilities for the
usbredirhost to confuse us.
This is a preparation patch for completely getting rid of the async-packet
struct in usb-redir, instead relying on the (new) per ep queues in the
qemu usb core.

In order for redirection to work properly when redirecting to an emulated
XHCI controller, the usb-redir-host must support both
usb_redir_cap_ep_info_max_packet_size and usb_redir_cap_64bits_ids,
reject any devices redirected to an XHCI controller when these are not

original xhci code (the one which used libusb directly) used to use
'background transfers' for iso streams. In upstream qemu the iso
stream buffering is handled by usb-host & usb-redir, so we will
never ever need this. It has been left in as reference, but is dead
code anyway. Rip it out.

From: Gerd Hoffmann @ 2012-09-06 7:12 UTC (permalink / raw)
To: qemu-devel; +Cc: Gerd Hoffmann
This patch splits the xhci_xfer_data function into three.
The xhci_xfer_data function used to do does two things:
(1) copy transfer data between guest memory and a temporary buffer.
(2) report transfer results to the guest using events.
Now we three functions to handle this:
(1) xhci_xfer_map creates a scatter list for the transfer and
uses that (instead of the temporary buffer) to build a
USBPacket.
(2) xhci_xfer_unmap undoes the mapping.
(3) xhci_xfer_report sends out events.
The patch also fixes reporting of transaction errors which must be
reported unconditinally, not only in case the guest asks for it
using the ISP flag.

Change the register layout to be a bit more sparse and also not depend
on the number of ports. Useful when for making the number of ports
runtime-configurable.

This patch changes the way xhci ports are linked to USBPorts. The fixed
1:1 relationship between xhci ports and USBPorts is gone. Now each
USBPort represents a physical plug which has usually two xhci ports
assigned: one usb2 and ond usb3 port. usb devices show up at one or the
other, depending on whenever they support superspeed or not.
This patch also makes the number of usb2 and usb3 ports runtime
configurable by adding 'p2' and 'p3' properties. It is allowed to
have different numbers of usb2 and usb3 ports. Specifying p2=4,p3=2
will give you an xhci adapter which supports all speeds on physical
ports 1+2 and usb2 only on ports 3+4.

Drop custom write_config function which isn't needed any more.
Make the msi property a bit property so it accepts 'on' & 'off'.
Enable MSI by default.
TODO: add compat property to disable on old machine types.

Split xhci_irq_update into a function which handles intx updates
(including lowering the irq line once the guests acks the interrupt)
and one which is used for raising an irq only.
