ASSERT (TrsRing != NULL) [4]
UsbEnumerateNewDev() in the USB bus driver issues a GET_DESCRIPTOR
request, in order to determine the number of configurations that the
endpoint supports. The requests consists of three stages (three TRBs),
setup, data, and status. The length of the response is determined in [1],
namely from the transfer event that the host controller generates in
response to the request's middle stage (ie. the data stage).
If the length of the answer is correct (a full GET_DESCRIPTOR request
takes 18 bytes), then the XHCI driver that underlies the USB bus driver
"snoops" (caches) the descriptor data for later [2].
Later, the USB bus driver sends a SET_CONFIG request. The underlying XHCI
driver allocates a transfer ring for the endpoint, relying on the data
snooped and cached in step [2].
Finally, the USB keyboard driver submits an asynchronous interrupt
transfer to manage the keyboard. As part of this it asserts [4] that the
ring has been allocated in step [3].
And this ASSERT() fires. The root cause can be found in the way QEMU
handles the initial GET_DESCRIPTOR request.
Again, that request consists of three stages (TRBs, Transfer Request
Blocks), "setup", "data", and "status". The XhcCreateTransferTrb()
function sets the IOC ("Interrupt on Completion") flag in each of these
TRBs.
According to the XHCI specification, the host controller shall generate a
Transfer Event in response to *each* individual TRB of the request that
had the IOC flag set. This means that QEMU should queue three events:
setup, data, and status, for edk2's XHCI driver.
However, QEMU only generates two events:
- one for the setup (ie. 1st) stage,
- another for the status (ie. 3rd) stage.
No event is generated for the middle (ie. data) stage. The loop in QEMU's
xhci_xfer_report() function runs three times, but due to the "reported"
variable, only the first and the last TRBs elicit events, the middle (data
stage) results in no event queued.
As a consequence:
- When handling the GET_DESCRIPTOR request, XhcCheckUrbResult() in [1]
does not update the response length from zero.
- XhcControlTransfer() thinks that the response is invalid (it has zero
length payload instead of 18 bytes), hence [2] is not reached; the
device descriptor is not stashed for later, and the number of possible
configurations is left at zero.
- When handling the SET_CONFIG request, (NumConfigurations == 0) from
above prevents the allocation of the endpoint's transfer ring.
- When the keyboard driver tries to use the endpoint, the ASSERT() blows
up.
The solution is to correct the emulation in QEMU, and to generate a
transfer event whenever IOC is set in a TRB.
The patch replaces
!reported && (IOC || foo) == !reported && IOC ||
!reported && foo
with
IOC || (!reported && foo) == IOC ||
!reported && foo
which only changes how
reported && IOC
is handled. (Namely, it now generates an event.)
Tested with edk2 built for "qemu-system-aarch64 -M virt" (ie.
"ArmVirtualizationQemu.dsc", aka "AAVMF"), and guest Linux.

USBDevice's realize method usb_qdev_realize() automatically creates a
usb-hub when only one port is left. Creating devices in realize
methods is questionable, but works.
If usb-hub creation fails, an error is reported to stderr, but the
failure is otherwise ignored. We then create the actual device using
the last port, which may well succeed.
Example:
$ qemu -nodefaults -S -display none -machine usb=on -monitor stdio
QEMU 2.2.50 monitor - type 'help' for more information
(qemu) device_add usb-mouse
[Repeat 36 times]

Device 0.0, Port 2, Speed 12 Mb/s, Product QEMU USB Hub
Device 0.0, Port 2.1, Speed 12 Mb/s, Product QEMU USB Mouse
[More mice and hubs omitted...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
(qemu) device_add usb-mouse
usb hub chain too deep

(qemu) info usb
[...]
Device 0.0, Port 2.8.8.8.8.7, Speed 12 Mb/s, Product QEMU USB Mouse
Device 0.0, Port 2.8.8.8.8.8, Speed 12 Mb/s, Product QEMU USB Mouse
Despite the "Failed" message, the command actually succeeded.
In QMP, it's worse. When adding the 37th mouse via QMP, the command
fails with
{"error": {"class": "GenericError", "desc": "usb hub chain too deep"}}
Additionally, "Failed to initialize USB device 'usb-hub'" is reported
on stderr. Despite the command failure, the device was created. This
is wrong.
Fix by avoiding qdev_init() for usb-hub creation, so we can ignore
errors cleanly.

Most LegacyUSBFactory usbdevice_init() methods realize with
qdev_init_nofail(), even though their caller usbdevice_create() can
handle failure. Okay if it really can't fail (I didn't check), but
somewhat brittle.
usb_msd_init() and usb_bt_init() call qdev_init(). The latter
additionally reports an error when qdev_init() fails.
Realization failure produces multiple error reports: a specific one
from qdev_init(), and generic ones from usb_bt_init(),
usb_create_simple(), usbdevice_create() and usb_parse().
Remove realization from the usbdevice_init() methods. Realize in
usbdevice_create(), and produce exactly one error message there. You
still get another one from usb_parse().

Device models should access their block backends only through the
block-backend.h API. Convert them, and drop direct includes of
inappropriate headers.
Just four uses of BlockDriverState are left:
* The Xen paravirtual block device backend (xen_disk.c) opens images
itself when set up via xenbus, bypassing blockdev.c. I figure it
should go through qmp_blockdev_add() instead.
* Device model "usb-storage" prompts for keys. No other device model
does, and this one probably shouldn't do it, either.
* ide_issue_trim_cb() uses bdrv_aio_discard() instead of
blk_aio_discard() because it fishes its backend out of a BlockAIOCB,
which has only the BlockDriverState.
* PC87312State has an unused BlockDriverState[] member.
The next two commits take care of the latter two.

usb_msd_init() calls qemu_opts_create() with a made-up ID and false
fail_if_exists. If the ID already exists, it happily messes up those

Add back the PCIe config capabilities on XHCI cards in non-PCIe slots,
but only for machine types before 2.1.
This fixes a migration incompatibility in the XHCI PCI devices
caused by:
058fdcf52c - xhci: add endpoint cap on express bus only
Note that in fixing it for compatibility with older QEMUs, it breaks
compatibility with existing QEMU 2.1's on older machine types.
The status before this patch was (if it used an XHCI adapter):
machine type | source qemu
any pre-2.1 - FAIL
any 2.1... - PASS
With this patch:
machine type | source qemu
any pre-2.1 - PASS
pre-2.1 2.1... - FAIL
2.1 2.1... - PASS
A test to trigger it is to add '-device nec-usb-xhci,id=xhci,addr=0x12'

We identify devices by their Open Firmware device paths. The encoding
of the host controller and hub port numbers is incorrect:
usb_get_fw_dev_path() formats them in decimal, while SeaBIOS uses
hexadecimal. When some port number > 9, SeaBIOS will miss the
bootindex (lucky case), or apply it to another device (unlucky case).
The relevant spec[*] agrees with SeaBIOS (and OVMF, for that matter).
Change %d to %x.
Bug can bite only with host controllers or hubs sporting more than ten
ports. I'm not aware of any.

"vmstate_xhci_event" was introduced in commit 37352df3 ("xhci: add live
migration support"), and first released in v1.6.0. The field list in this
VMSD is not terminated with the VMSTATE_END_OF_LIST() macro.
During normal use (ie. migration), the issue is practically invisible,
because the "vmstate_xhci_event" object (with the unterminated field list)
is only ever referenced -- via "vmstate_xhci_intr" -- if xhci_er_full()
returns true, for the "ev_buffer" test. Since that field_exists() check
(apparently) almost always returns false, we almost never traverse
"vmstate_xhci_event" during migration, which hides the bug.
However, Amit's vmstate checker forces recursion into this VMSD as well,
and the lack of VMSTATE_END_OF_LIST() breaks the field list terminator
check (field->name != NULL) in dump_vmstate_vmsd(). The result is
undefined behavior, which in my case translates to infinite recursion
(because the loop happens to overflow into "vmstate_xhci_intr", which then
links back to "vmstate_xhci_event").
Add the missing terminator.

On FreeBSD polling a master pty while the other end is not connected
with G_IO_OUT only results in an endless wait. This is different from
the Linux behaviour, that returns immediately. In order to demonstrate
this, I have the following example code:
http://xenbits.xen.org/people/royger/test_poll.c
When executed on Linux:
$ ./test_poll
In callback
On FreeBSD instead, the callback never gets called:
$ ./test_poll
So, in order to workaround this, poll the source with G_IO_HUP (which
makes the code behave the same way on both Linux and FreeBSD).

We can pick the usb port speed in generic code, by looking at the port

This way we can set the device speed before calling port->ops->attach,

While at it, rename variables to better reflect reality: libcacard_*

Note this code is not as KISS as I would like, the reason for this is that
the Linux kernel interface wants streams on eps belonging to one interface

to the kernel API.

Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>
This patch mirrors a patch to the Linux uas kernel driver which I've just
submitted. It looks like the qemu uas struct definitions were taken from
the Linux kernel driver, and have inherited the same mistake.
Besides fixing the response iu struct, the patch also drops the add_info
parameter from the usb_uas_queue_response() function, it is always 0 anyways,
and expressing 3 zero-bytes as a function argument is a bit hard.
Below is the long explanation for this change taken from the kernel commit:
The response iu struct before this patch has a size of 7 bytes, which is weird
since all other iu-s are explictly padded to a multiple of 4 bytes.
Submitting a 7 byte bulk transfer to the status endpoint of a real uasp device
when expecting a response iu results in an USB babble error, as the device
actually sends 8 bytes.
Up on closer reading of the UAS spec:
http://www.t10.org/cgi-bin/ac.pl?t=f&f=uas2r00.pdf
The reason for this becomes clear, the 2 entries in "Table 17 — RESPONSE IU"
are numbered 4 and 6, looking at other iu definitions in the spec, esp.
multi-byte fields, this indicates that the ADDITIONAL RESPONSE INFORMATION
field is not a 2 byte field as one might assume at a first look, but is
a multi-byte field containing 3 bytes.
This also aligns with the SCSI Architecture Model 4 spec, which UAS is based
on which states in paragraph "7.1 Task management function procedure calls"
that the "Additional Response Information" output argument for a Task
management function procedure call is 3 bytes.
Last but not least I've verified this by sending a logical unit reset task
management call with an invalid lun to an actual uasp device, and received
back a response-iu with byte 6 being 0, and byte 7 being 9, which is the
responce code for an invalid iu, which confirms that the response code is
being reported in byte 7 of the response iu rather then in byte 6.

The OS can ask the xhci controller to save and restore its
internal state, which is used by the OS when the system is
suspended and resumed.
This patch handles writes to the save + restore bits in the
command register. Only thing it does is updating the
restore error bit in the status register to signal an error
on restore. The guest OS should do a full reinitialization
after resume then.
This is the minimal patch which gets S3 going with xhci.
Implementing full save/restore support is TBD.

One of the reworks of qemu's usb core made changes to usb-port's disconnect
handling. Now ports with a device will always have a non 0 dev member, but
if the device is not attached (which is possible with usb redirection),
dev->attached will be 0.
So supplement all checks for dev to also check dev->attached, and add an
extra check in a path where a device check was completely missing.
This fixes various crashes (asserts triggering) I've been seeing when xhci
attached usb devices get disconnected at the wrong time.

The qdev_free() function name is misleading since all the function does
is unlink the device from its parent. The device is not necessarily
freed.
The device will be freed when its QObject refcount reaches zero. It is
usual for the parent (bus) to hold the final reference but there are
cases where something else holds a reference so "free" is a misleading
name.
Call object_unparent(obj) directly instead of having a qdev wrapper
function.

With streams the endpoint context dequeue pointer should point to the

At least Linux guests expect it to point to value set by an set_ep_dequeue

Quoting from: linux/Documentation/ABI/stable/sysfs-bus-usb:
Note that some devices, in violation of the USB spec, have a
configuration with a value equal to 0. Writing 0 to
bConfigurationValue for these devices will install that
configuration, rather then unconfigure the device.
So don't compare the configuration value against 0 to check for unconfigured
devices, instead check for a LIBUSB_ERROR_NOT_FOUND return from
libusb_get_active_config_descriptor().

The guest will issue an initial device reset when the device is attached, but
since the current usb-host-libusb code only actually does the reset when
udev->configuration != 0, and on attach the device is not yet configured,
the reset gets ignored. This means that the device gets passed to the guest
in an unknown state, which is not good.
The udev->configuration check is there because of the release / claim
interfaces done around the libusb_device_reset call, but these are not
necessary. If interfaces are claimed when libusb_device_reset gets called
libusb will release + reclaim them itself.
The usb_host_ep_update call also is not necessary. If the reset succeeds the
original config and interface alt settings will be restored.
Last if the reset fails, that means the device has either disconnected or
morphed into an another device and has been completely re-enumerated,
so it is treated by the host as a new device and our handle is invalid,
so on reset failure we need to call usb_host_nodev().

The name field in a VMStateDescription is part of the migration state
versioning, so changing it will break migration. It's therefore a
bad idea to use a QOM typename macro to initialize it, because in
general we're free to rename QOM types as part of code refactoring
and cleanup. For the handful of devices that were doing this by
mistake, replace the QOM typenames with the corresponding literal

Due to various unfortunate reasons we cannot reliable detect a guest
cancelling a packet as soon as it happens, instead we detect cancels
with some delay.
When packets are handled async, and we directly pass the guest memory for
the packet to the usb-device as iovec, this means that the usb-device can
write to guest-memory which the guest has already re-used for other purposes
-> not good!
This patch fixes this by adding an intermediate buffer and writing back not
only the result, but also the data, of async completed packets when scanning
the schedule.

With pipelining it is possible to encounter a finished packet when cleaning
the queue due to a halt. This happens when a non stall error happens while
talking to a real device. In this case the queue on the usb-host side will
continue processing packets, and we can have completed packets waiting in
the queue after an error condition packet causing a halt.
There are 2 reasons to discard the completed packets at this point, rather
then trying to writing them back to the guest:
1) The guest expect to be able to cancel and/or change packets after the
packet with the error without doing an unlink, so writing them back may
confuse the guest.
2) Since the queue does not advance when halted, the writing back of these
packets will fail anyways since p->qtdaddr != q->qtdaddr, so the
ehci_verify_qtd call in ehci_writeback_async_complete_packet will fail.
Note that 2) means that then only functional change this patch introduces
is the printing of a warning when this scenario happens.
Note that discarding these packets means that the guest driver and the device
will get out of sync! This is unfortunate, but should not be a problem since
with a non stall error (iow an io-error) the 2 are out of sync already anyways.
Still this patch adds a warning to signal this happening.
Note that sofar this has only been seen with a DVB-T receiver, which gives
of a MPEG-2 stream, which allows for recovering from lost packets, see:

Reimplement usb-host on top of libusb.
Reasons to do this:
(1) Largely rewritten from scratch, nice opportunity to kill historical
cruft.
(2) Offload usbfs handling to libusb.
(3) Have a single portable code base instead of bsd + linux variants.
(4) Bring usb-host support to any platform supported by libusbx.
For now this goes side-by-side to the existing code. That is only to
simplify regression testing though, at the end of the day I want remove
the old code and support libusb exclusively. Merge early in 1.5 cycle,
remove the old code after 1.5 release or something like this.
Thanks to qdev the old and new code can coexist nicely on linux. Just
use "-device usb-host-linux" to use the old linux driver instead of the
libusb one (which takes over the "usb-host" name).
The bsd driver isn't qdev'ified so it isn't that easy for bsd.
I didn't bother making it runtime switchable, so you have to rebuild
qemu with --disable-libusb to get back the old code.

usb-serial has a qdev chardev property, and hw/qdev-properties-system.c
already contains:
static void release_chr(Object *obj, const char *name, void *opaque)
{
DeviceState *dev = DEVICE(obj);
Property *prop = opaque;
CharDriverState **ptr = qdev_get_prop_ptr(dev, prop);
CharDriverState *chr = *ptr;
if (chr) {
qemu_chr_add_handlers(chr, NULL, NULL, NULL, NULL);
qemu_chr_fe_release(chr);
}
}
So doing the qemu_chr_add_handlers(s->cs, NULL, NULL, NULL, NULL); from
the usb handle_destroy function too will lead to it being done twice.

And allow frontends which can actually determine if the guest is listening to
