      usb-storage: Fix how legacy init handles option ID clash · 31376776
      由 Markus Armbruster 提交于 
      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.

      xhci PCIe endpoint migration compatibility fix · e6043e92
      由 Dr. David Alan Gilbert 提交于 
      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:
   058fdcf5 - 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.

      Reason: we don't want commit to that interface yet.  Possibly
the implementation will be switched over to use fsdev.

      vmstate_xhci_event: fix unterminated field list · 3afca1d6
      由 Laszlo Ersek 提交于 
      "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.

      mtp: linux guest detection fix. · 13d54125
      由 Gerd Hoffmann 提交于 
      Attach a name to the MTP interface (android phones have this too).

With this patch recent linux guests such as fedora 20 happily detect and
use the device.  It shows up in nautilus file manager automatically, and
simple-mtpfs can mount it.

      serial: poll the serial console with G_IO_HUP · e02bc6de
      由 Roger Pau Monne 提交于 
      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).
