Gerd Hoffmann f419a626c7 usb/uhci: move pid check
commit "5f77e06 usb: add pid check at the first of uhci_handle_td()"
moved the pid verification to the start of the uhci_handle_td function,
to simplify the error handling (we don't have to free stuff which we
didn't allocate in the first place ...).

Problem is now the check fires too often, it raises error IRQs even for
TDs which we are not going to process because they are not set active.

So, lets move down the check a bit, so it is done only for active TDs,
but still before we are going to allocate stuff to process the requested
transfer.

Gerd Hoffmann 1ae3f2f178 ehci: apply limit to iTD/sidt descriptors
Commit "156a2e4 ehci: make idt processing more robust" tries to avoid a
DoS by the guest (create a circular iTD queue and let qemu ehci
emulation run in circles forever).  Unfortunately this has two problems:
First it misses the case of siTDs, and second it reportedly breaks
FreeBSD.

So lets go for a different approach: just count the number of iTDs and
siTDs we have seen per frame and apply a limit.  That should really
catch all cases now.

Rutuja Shah 73bcb24d93 Replaced get_tick_per_sec() by NANOSECONDS_PER_SECOND
This patch replaces get_ticks_per_sec() calls with the macro
NANOSECONDS_PER_SECOND. Also, as there are no callers, get_ticks_per_sec()
is then removed.  This replacement improves the readability and
understandability of code.

For example,

    timer_mod(fdctrl->result_timer,
	      qemu_clock_get_ns(QEMU_CLOCK_VIRTUAL) + (get_ticks_per_sec() / 50));

NANOSECONDS_PER_SECOND makes it obvious that qemu_clock_get_ns
matches the unit of the expression on the right side of the plus.

Markus Armbruster da34e65cb4 include/qemu/osdep.h: Don't include qapi/error.h
Commit 57cb38b included qapi/error.h into qemu/osdep.h to get the
Error typedef.  Since then, we've moved to include qemu/osdep.h
everywhere.  Its file comment explains: "To avoid getting into
possible circular include dependencies, this file should not include
any other QEMU headers, with the exceptions of config-host.h,
compiler.h, os-posix.h and os-win32.h, all of which are doing a
similar job to this file and are under similar constraints."
qapi/error.h doesn't do a similar job, and it doesn't adhere to
similar constraints: it includes qapi-types.h.  That's in excess of
100KiB of crap most .c files don't actually need.

Add the typedef to qemu/typedefs.h, and include that instead of
qapi/error.h.  Include qapi/error.h in .c files that need it and don't
get it now.  Include qapi-types.h in qom/object.h for uint16List.

Update scripts/clean-includes accordingly.  Update it further to match
reality: replace config.h by config-target.h, add sysemu/os-posix.h,
sysemu/os-win32.h.  Update the list of includes in the qemu/osdep.h
comment quoted above similarly.

This reduces the number of objects depending on qapi/error.h from "all
of them" to less than a third.  Unfortunately, the number depending on
qapi-types.h shrinks only a little.  More work is needed for that one.

Gonglei 5f77e06baa usb: add pid check at the first of uhci_handle_td()
pid can be gotten from uhci device memory in uhci_handle_td(),
so the guest can trigger assert qemu if we get an invalid pid.
And the uhci spec 2.1.2 tells us The Host Controller sets Host
Controller Process Error bit to 1 when it detects a fatal error
and indicates that the Host Controller suffered a consistency
check failure while processing a Transfer Descriptor. An example
of a consistency check failure would be finding an illegal PID
field while processing the packet header portion of the TD.
When this error occurs, the Host Controller clears the Run/Stop
bit in the Command register to prevent further schedule execution.

We'd better to set UHCI_STS_HCPERR and kick an interrupt, check
the pid value at the first of uhci_handle_td function.

Eric Blake d7bce9999d qom: Swap 'name' next to visitor in ObjectPropertyAccessor
Similar to the previous patch, it's nice to have all functions
in the tree that involve a visitor and a name for conversion to
or from QAPI to consistently stick the 'name' parameter next
to the Visitor parameter.

Done by manually changing include/qom/object.h and qom/object.c,
then running this Coccinelle script and touching up the fallout
(Coccinelle insisted on adding some trailing whitespace).

Eric Blake 51e72bc1dd qapi: Swap visit_* arguments for consistent 'name' placement
JSON uses "name":value, but many of our visitor interfaces were
called with visit_type_FOO(v, &value, name, errp).  This can be
a bit confusing to have to mentally swap the parameter order to
match JSON order.  It's particularly bad for visit_start_struct(),
where the 'name' parameter is smack in the middle of the
otherwise-related group of 'obj, kind, size' parameters! It's
time to do a global swap of the parameter ordering, so that the
'name' parameter is always immediately after the Visitor argument.

Additional reason in favor of the swap: the existing include/qjson.h
prefers listing 'name' first in json_prop_*(), and I have plans to
unify that file with the qapi visitors; listing 'name' first in
qapi will minimize churn to the (admittedly few) qjson.h clients.

Later patches will then fix docs, object.h, visitor-impl.h, and
those clients to match.

Done by first patching scripts/qapi*.py by hand to make generated
files do what I want, then by running the following Coccinelle
script to affect the rest of the code base:
 $ spatch --sp-file script `git grep -l '\bvisit_' -- '**/*.[ch]'`
I then had to apply some touchups (Coccinelle insisted on TAB
indentation in visitor.h, and botched the signature of
visit_type_enum() by rewriting 'const char *const strings[]' to
the syntactically invalid 'const char*const[] strings').  The
movement of parameters is sufficient to provoke compiler errors
if any callers were missed.

Laurent Vivier 087462c773 ohci: clear pending SOF on suspend
On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.

On suspend, if a SOF interrupt is raised between the stop of the
device processing and the change of the device internal state to
OHCI_USB_SUSPEND (QEMU stops SOF timer on this state change), this
interrupt is never acknowledged.

This patch clears pending SOF interrupt on OHCI_USB_SUSPEND setting.

Some details:

- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
  only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
  So if this interrupt happens and the driver is not in this state,
  the function is called again and again, moving the system to a
  CPU starvation.

- ohci_rh_suspend(): the function stop the operation and acknowledge
  pending interrupts (but doesn't disable it). Later in the function,
  the device is moved to OHCI_SUSPEND_STATE, and the driver to
  OHCI_RH_SUSPENDED. If between the moment when the interrupt is
  acknowledged and the moment when the device is suspended a new
  interrupt is raised, it will be never acknowledged because the
  driver is now not in OHCI_RH_RUNNING state.

Laurent Vivier fd0a10cd20 ohci: delay first SOF interrupt
On overcommitted CPU, kernel can be so slow that an interrupt can
be triggered by the device whereas the driver is not ready to receive
it. This drives us into an infinite loop.

This does not happen on real hardware because real hardware never send
interrupt immediately after the controller has been moved to OPERATION state.

This patch tries to delay the first SOF interrupt to let driver exits from
the critical section (which is not protected against interrupts...)

Some details:

- ohci_irq(): the OHCI interrupt handler, acknowledges the SOF IRQ
  only if the state of the driver (rh_state) is OHCI_STATE_RUNNING.
  So if this interrupt happens and the driver is not in this state,
  the function is called again and again, moving the system to a
  CPU starvation.

- ohci_rh_resume(): the driver re-enables operation with OHCI_USB_OPER.
  In QEMU this start the SOF timer and QEMU starts to send IRQs. As
  the driver is not in OHCI_STATE_RUNNING and not protected against IRQ,
  the ohci_irq() can be called and the driver never moved to
  OHCI_STATE_RUNNING.

g_new(T, n) is neater than g_malloc(sizeof(T) * n).  It's also safer,

Two, it returns T * rather than void *, which lets the compiler catch
more type errors.

sizeof(T).  Same Coccinelle semantic patch as in commit b45c03f.

Gerd Hoffmann cbf82fa01e ehci: clear suspend bit on detach
When a device is detached, clear the suspend bit (PORTSC_SUSPEND)
in the port status register.

The specs are not *that* clear what is supposed to happen in case
a suspended device is unplugged.  But the enable bit (PORTSC_PED)
is cleared, and the specs mention setting suspend with enable being
unset is undefined behavior.  So clearing them both looks reasonable,
and it actually fixes the reported bug.

Markus Armbruster 70b9433109 QemuOpts: Wean off qerror_report_err()
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP.  It should not be used
elsewhere.

The only remaining user in qemu-option.c is qemu_opts_parse().  Is it
used in QMP context?  If not, we can simply replace
qerror_report_err() by error_report_err().

The uses in qemu-img.c, qemu-io.c, qemu-nbd.c and under tests/ are
clearly not in QMP context.

The uses in vl.c aren't either, because the only QMP command handlers
there are qmp_query_status() and qmp_query_machines(), and they don't
call it.

Remaining uses:

* drive_def(): Command line -drive and such, HMP drive_add and pci_add

* hmp_chardev_add(): HMP chardev-add

* monitor_parse_command(): HMP core

* tmp_config_parse(): Command line -tpmdev

* net_host_device_add(): HMP host_net_add

* net_client_parse(): Command line -net and -netdev

* qemu_global_option(): Command line -global

* vnc_parse_func(): Command line -display, -vnc, default display, HMP
  change, QMP change.  Bummer.

* qemu_pci_hot_add_nic(): HMP pci_add

* usb_net_init(): Command line -usbdevice, HMP usb_add

Propagate errors through qemu_opts_parse().  Create a convenience
function qemu_opts_parse_noisily() that passes errors to
error_report_err().  Switch all non-QMP users outside tests to it.

That leaves vnc_parse_func().  Propagate errors through it.  Since I'm
touching it anyway, rename it to vnc_parse().

Michal Kazior 278412d0e7 usb: fix usb-net segfault
The dev->config pointer isn't set until guest
system initializes usb devices (via
usb_desc_set_config). However qemu networking can
go through some motions prior to that, e.g.:

 #0  is_rndis (s=0x555557261970) at hw/usb/dev-network.c:653
 #1  0x000055555585f723 in usbnet_can_receive (nc=0x55555641e820) at hw/usb/dev-network.c:1315
 #2  0x000055555587635e in qemu_can_send_packet (sender=0x5555572660a0) at net/net.c:470
 #3  0x0000555555878e34 in net_hub_port_can_receive (nc=0x5555562d7800) at net/hub.c:101
 #4  0x000055555587635e in qemu_can_send_packet (sender=0x5555562d7980) at net/net.c:470
 #5  0x000055555587dbca in tap_can_send (opaque=0x5555562d7980) at net/tap.c:172

The command to reproduce most reliably was:

 qemu-system-i386 -usb -device usb-net,vlan=0 -net tap,vlan=0

This wasn't strictly a problem with tap. Other
networking endpoints (vde, user) could trigger
this problem as well.

Boards that do not include an USB controller should not provide
USB devices. However, when running "qemu-system-s390x -device help"
for example, there's still a usb-hub, usb-kbd, usb-mouse and
usb-tablet in the list of "supported" devices. Let's fix that
by compiling and linking the USB files only if it is really
necessary.

Markus Armbruster c326529b74 usb/dev-storage: Avoid qerror_report_err() outside QMP handlers
qerror_report_err() is a transitional interface to help with
converting existing monitor commands to QMP.  It should not be used
elsewhere.

usb_msd_password_cb() is only called from within an HMP command
handler.  Replace by error_report_err().

Markus Armbruster 7afcc1f9ba usb/dev-storage: Fix QMP device_add missing encryption key failure
When the image is encrypted, QMP device_add creates the device, defers
actually attaching it to when the key becomes available, then returns
an error.  This is wrong.  device_add must either create the device
and succeed, or do nothing and fail.

The bug is in usb_msd_realize_storage().  It posts an error with
qerror_report_err(), and returns success.  Device realization relies
on the return value, and completes.  The QMP monitor, however, relies
on the posted error, and sends it in an error reply.

Reproducer:

    $ qemu-system-x86_64 -nodefaults -display none -usb -qmp stdio -drive if=none,id=foo,file=geheim.qcow2
    {"QMP": {"version": {"qemu": {"micro": 50, "minor": 2, "major": 2}, "package": ""}, "capabilities": []}}
    { "execute": "qmp_capabilities" }
    {"return": {}}
    { "execute": "device_add", "arguments": { "driver": "usb-storage", "id": "bar", "drive": "foo" } }
    {"error": {"class": "DeviceEncrypted", "desc": "'foo' (geheim.qcow2) is encrypted"}}

Even though we got an error back, the device got created just fine.
To demonstrate, let's unplug it again:

    {"execute":"device_del","arguments": { "id": "bar" } }
    {"timestamp": {"seconds": 1426003440, "microseconds": 237181}, "event": "DEVICE_DELETED", "data": {"path": "/machine/peripheral/bar/bar.0/legacy[0]"}}
    {"timestamp": {"seconds": 1426003440, "microseconds": 238231}, "event": "DEVICE_DELETED", "data": {"device": "bar", "path": "/machine/peripheral/bar"}}
    {"return": {}}

Fix by making usb_msd_realize_storage() fail properly.

Markus Armbruster 9b14e0efcc monitor usb: Inline monitor_read_bdrv_key_start()'s first part
monitor_read_bdrv_key_start() does several things:

1. If no key is needed, call completion_cb() and succeed

2. If we're in QMP context, call qerror_report_err() and fail

3. Start reading the key in the monitor.

This is two things too many.  Inline 1. and 2. into its callers
monitor_read_block_device_key() and usb_msd_realize_storage().

Since monitor_read_block_device_key() only ever runs in HMP context,
drop 2. there.

The next commit will clean up the result in usb_msd_realize_storage().

Ekaterina Tumanova 0eb28a4228 BlockConf: Call backend functions to detect geometry and blocksizes
geometry: hd_geometry_guess function autodetects the drive geometry.
This patch adds a block backend call, that probes the backing device
geometry. If the inner driver method is implemented and succeeds
(currently only for DASDs), the blkconf_geometry will pass-through
the backing device geometry. Otherwise will fallback to old logic.

blocksize: This patch initializes blocksize properties to 0.
In order to set the property a blkconf_blocksizes was introduced.
If user didn't set physical or logical blocksize, it will
retrieve its value from a driver (only succeeds for DASD), otherwise
it will set default 512 value.

The blkconf_blocksizes call was added to all users of BlkConf.

Markus Armbruster 9b3d111ad9 hw: Propagate errors through qdev_prop_set_drive()
Three kinds of callers:

1. On failure, report the error and abort

   Passing &error_abort does the job.  No functional change.

2. On failure, report the error and exit()

   This is qdev_prop_set_drive_nofail().  Error reporting moves from
   qdev_prop_set_drive() to its caller.  Because hiding away the error
   in the monitor right before exit() isn't helpful, replace
   qerror_report_err() by error_report_err().  Shouldn't make a
   difference, because qdev_prop_set_drive_nofail() should never be
   used in QMP context.

3. On failure, report the error and recover

   This is usb_msd_init() and scsi_bus_legacy_add_drive().  Error
   reporting and freeing the error object moves from
   qdev_prop_set_drive() to its callers.

   Because usb_msd_init() can't run in QMP context, replace
   qerror_report_err() by error_report_err() there.

   No functional change.

   scsi_bus_legacy_add_drive() calling qerror_report_err() is of
   course inappropriate, but this commit merely makes it more obvious.
   The next one will clean it up.

              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.

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.

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.

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

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).

and
     .fields =      (VMStateField []) {

Change all the combinations to:

     .fields = (VMStateField[]){

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.
