Laszlo Ersek aa6857891d xhci: generate a Transfer Event for each Transfer TRB with the IOC bit set
At the moment, when the XHCI driver in edk2
(MdeModulePkg/Bus/Pci/XhciDxe/XhciDxe.inf) runs on QEMU, with the options

  -device nec-usb-xhci -device usb-kbd

it crashes with:

  ASSERT MdeModulePkg/Bus/Pci/XhciDxe/XhciSched.c(1759):
  TrsRing != ((void*) 0)

The crash hits in the following edk2 call sequence (all files under
MdeModulePkg/Bus/):

              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.

Markus Armbruster f43e47dbf6 QemuOpts: Drop qemu_opt_set(), rename qemu_opt_set_err(), fix use
qemu_opt_set() is a wrapper around qemu_opt_set() that reports the
error with qerror_report_err().

Most of its users assume the function can't fail.  Make them use
qemu_opt_set_err() with &error_abort, so that should the assumption
ever break, it'll break noisily.

Just two users remain, in util/qemu-config.c.  Switch them to
qemu_opt_set_err() as well, then rename qemu_opt_set_err() to
qemu_opt_set().

Markus Armbruster bd8b92d5c8 usb: Suppress bogus error when automatic usb-hub creation fails
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]
    (qemu) info usb
      Device 0.0, Port 1, Speed 12 Mb/s, Product QEMU USB Mouse
      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
    Failed to initialize USB device 'usb-hub'
    (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.

Markus Armbruster 3bc36a401e usb: Improve -usbdevice error reporting a bit
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().

Markus Armbruster 4be746345f hw: Convert from BlockDriverState to BlockBackend, mostly
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.

Markus Armbruster fa1d36df74 block: Eliminate DriveInfo member bdrv, use blk_by_legacy_dinfo()
The patch is big, but all it really does is replacing

    dinfo->bdrv

by

    blk_bs(blk_by_legacy_dinfo(dinfo))

The replacement is repetitive, but the conversion of device models to
BlockBackend is imminent, and will shorten it to just
blk_legacy_dinfo(dinfo).

Line wrapping muddies the waters a bit.  I also omit tests whether
dinfo->bdrv is null, because it never is.

which are not supported by qdev property.

Because usb-storage rely on scsi-disk which is created
in usb_msg_realize_storage(), so we should store the SCSIDevice
pointer in MSDState struct. Only in this way, we can change
the global boot_order_list when we want to change the bootindex
during vm rebooting by calling object_property_set_int(Object(SCSIDevice),).

Markus Armbruster 31376776d0 usb-storage: Fix how legacy init handles option ID clash
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
options, then fails drive_new(), because the BlockDriverState with
that ID already exists, too.

Reproducer: -drive if=none,id=usb0,format=raw -usbdevice disk:tmp.qcow2

Pass true fail_if_exists to qemu_opts_create(), and if it fails, try
the next made-up ID.

The reproducer now succeeds, and creates an usb-storage device with ID
usb1.

Dr. David Alan Gilbert e6043e92c2 xhci PCIe endpoint migration compatibility fix
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'
to the command line.

Markus Armbruster 830cd54fca usb: Fix bootindex for portnr > 9
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.

Laszlo Ersek 3afca1d6d4 vmstate_xhci_event: fix unterminated field list
"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.

Roger Pau Monne e02bc6de30 serial: poll the serial console with G_IO_HUP
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).

Michael S. Tsirkin 719ffe1f5f usb: fix up post load checks
Correct post load checks:
1. dev->setup_len == sizeof(dev->data_buf)
    seems fine, no need to fail migration
2. When state is DATA, passing index > len
   will cause memcpy with negative length,
   resulting in heap overflow

First of the issues was reported by dgilbert.

Juan Quintela 6e3d652ab2 savevm: Remove all the unneeded version_minimum_id_old (usb)
After previous Peter patch, they are redundant.  This way we don't
assign them except when needed.  Once there, there were lots of case
where the ".fields" indentation was wrong:

     .fields = (VMStateField []) {
and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

The biggest problem (appart from aesthetics) was that checkpatch complained
when we copy&pasted the code from one place to another.

Michael Tokarev 9d171bd937 libcacard: remove libcacard-specific CFLAGS and LIBS from global vars
Currently all what's needed for single file libcacard/vcard_emul_nss.c
(libnss cflags) and hw/usb/ccid-card-emulated.c (libcacard includes)
together with the libs is added to global QEMU_CFLAGS and libs_softmmu.

Use the cflags only where really used (for two mentioned files), and
libs only where needed.

While at it, rename variables to better reflect reality: libcacard_*
is really nss_*.

This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs
(ditto for _cflags).  But in order to fix it, some more preparations
should be made first.  So add a FIXME comment.

setup_len and setup_index should be checked to make sure

error_is_set(&var) is the same as var != NULL, but it takes
whole-program analysis to figure that out.  Unnecessarily hard for
optimizers, static checkers, and human readers.  Dumb it down to
obvious.

Gets rid of several dozen Coverity false positives.

Note that the obvious form is already used in many places.

to the kernel API.

Hans de Goede 49cfa2fdc9 uas: Fix response iu struct definition
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.

Gerd Hoffmann f1f8bc218a xhci: add support for suspend/resume
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.

Hans de Goede de9de157fb xhci: Add a few missing checks for disconnected devices
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.

Hans de Goede 5af35d7fec usb-host-libusb: Fix reset handling
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().

Gerd Hoffmann b5613fdcb0 usb: remove old usb-host code
The usb-host code has been rewritten for qemu 1.5 to use libusb,
the old code has been left in as temporary fallback.  Now we are
two releases further out, targeting the 1.7 release.  No major
issues with the new code poped up until now.  Time to remove it
from tre tree.  Should we ever need it again for some reason --
git has a copy for us in the history.

Gerd Hoffmann bdebd6ee81 Revert "usb-hub: report status changes only once"
This reverts commit a309ee6e0a.

This isn't in line with the usb specification and adds regressions,
win7 fails to drive the usb hub for example.

Was added because it "solved" the issue of hubs interacting badly
with the xhci host controller.  Now with the root cause being fixed
in xhci (commit <FIXME>) we can revert this one.

Alexey Kardashevskiy cf66ee8e20 hcd-ohci: add dma error handling
Current hcd-ohci does not handle DMA errors. However they may happen
so here we introduce simple error handling.

On such errors, a typical OHCI will stop operating, signal the guest
about the error by sending "UnrecoverableError Event", set itself into
error state and set "Detected Parity Error" in its PCI config space
to signal that it got an error and so does the patch.

This also adds ohci_die() call to ohci_bus_start() to handle possible
failure of qemu_new_timer_ns().

Hans de Goede 9822261ce3 uhci: Use an intermediate buffer for usb packet data
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.

Alon Levy b16352acf3 ccid-card-passthru, dev-smartcard-reader: add debug environment variables
Introduces a new utility function: parse_debug_env to avoid code
duplication.

This overrides whatever debug value is set on the corresponding devices
from the command line, and is meant to ease the usage with any
management stack. For libvirt you can set environment variables by
extending the dom namespace, i.e:

<domain type='kvm' id='3' xmlns:qemu='http://libvirt.org/schemas/domain/qemu/1.0'>
  <qemu:commandline>
    <qemu:env name='QEMU_CCID_PASSTHRU_DEBUG' value='4'/>
    <qemu:env name='QEMU_CCID_DEBUG' value='4'/>
  </qemu:commandline>
</domain>

Hans de Goede e449f26bed ehci_free_packet: Discard finished packets when the queue is halted
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:

Gerd Hoffmann 2b2325ff64 use libusb for usb-host
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.

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.
