46dea4160d qemu-iotests: remove 085 and 087 from 'quick' group
The 'quick' group in qemu-iotests are not allowed to run QEMU since we
don't know which targets are available.  In other words, they may only
use qemu-img, qemu-io, and qemu-nbd.

Drop 085 and 087 from the 'quick' group since they run QEMU.  This
makes "make check-block" pass again.

dc668ded10 qemu-iotests: add 083 NBD client disconnect tests
This new test case uses nbd-fault-injector.py to simulate broken TCP
connections at each stage in the NBD protocol.  This way we can exercise
block/nbd-client.c's socket error handling code paths.

In particular, this serves as a regression test to make sure
nbd-client.c doesn't cause an infinite loop by leaving its
nbd_receive_reply() fd handler registered after the connection has been
closed.  This bug was fixed in an earlier patch.

1e8ece0db3 tests: add nbd-fault-injector.py utility
The nbd-fault-injector.py script is a special kind of NBD server.  It
throws away all writes and produces zeroes for reads.  Given a list of
fault injection rules, it can simulate NBD protocol errors and is useful
for testing NBD client error handling code paths.

See the patch for documentation.  This scripts is modelled after Kevin
Wolf <kwolf@redhat.com>'s blkdebug block driver.

4a41a2d68a nbd: close socket if connection breaks
nbd_receive_reply() is called by the event loop whenever data is
available or the socket has been closed by the remote side.

This patch closes the socket when an error occurs to prevent the
nbd_receive_reply() handler from being called indefinitely after the
connection has failed.

Note that we were already correctly returning EIO for pending requests
but leaving the nbd_receive_reply() handler registered resulted in high
CPU consumption and a flood of error messages.

Reuse nbd_teardown_connection() to close the socket.

c3adb58fe0 blockdev: Refuse to open encrypted image unless paused
Opening an encrypted image takes an additional step: setting the key.
Between open and the key set, the image must not be used.

We have some protection against accidental use in place: you can't
unpause a guest while we're missing keys.  You can, however, hot-plug
block devices lacking keys into a running guest just fine, or insert
media lacking keys.  In the latter case, notifying the guest of the
insert is delayed until the key is set, which may suffice to protect
at least some guests in common usage.

This patch makes the protection apply in more cases, in a rather
heavy-handed way: it doesn't let you open encrypted images unless
we're in a paused state.

It doesn't extend the protection to users other than the guest (block
jobs?).  Use of runstate_check() from block.c is disgusting.  Best I
can do right now.

22956a3755 spapr-vscsi: fix CRQ status
Normally VIOSRP_OK (0) means success and non-zero value means error
except VIOSRP_OK2 (0x99) which is another success code by weird accident.

This uses 0 as success code always as some guests do not cope with
the 0x99 value well. The existing linux driver checks for both VIOSRP_OK
and VIOSRP_OK2 since 2.6.32.

This returns non-zero code (VIOSRP_ADAPTER_FAIL == 0x10) on errors which
can only happen if DMA write failed.

01c22f2cdd main-loop: Suppress "I/O thread spun" warnings for qtest
When running under qtest we don't actually have any vcpu threads
to be starved, so the warning about the I/O thread spinning isn't
relevant, and the way qtest manipulates the simulated clock means
the warning is produced a lot as a false positive. Suppress it if
qtest_enabled(), so 'make check' output is less noisy.

cb201b4872 qtest: Fix crash if SIGABRT during qtest_init()
If an assertion fails during qtest_init() the SIGABRT handler is
invoked.  This is the correct behavior since we need to kill the QEMU
process to avoid leaking it when the test dies.

The global_qtest pointer used by the SIGABRT handler is currently only
assigned after qtest_init() returns.  This results in a segfault if an
assertion failure occurs during qtest_init().

Move global_qtest assignment inside qtest_init().  Not pretty but let's
face it - the signal handler depends on global state.

Commit 0399a3819b (virtio-console: QOM

virtio-serial-bus.c, whereas virtserialport is the user-instantiatable
type in virtio-console.c. Therefore using TYPE_VIRTIO_CONSOLE_SERIAL_PORT.

7effdaa321 spapr: Fix return value of vga initialization
Before spapr_vga_init will returned false if the vga is specified by
the command '-device VGA' because vga_interface_type was evaluated to
VGA_NONE. With the change in previous patch of this series,
spapr_vga_init should return true if it's told that the vga will be
initialized in flow of the generic devices initialization.

To keep '-nodefaults' have the semantics of bare minimum, it adds a
check of 'has_defaults' in usb_enabled() to avoid that a USB controller
is added by '-nodefautls, -device VGA' implicitly.

This patch also makes two cleanups:
1. skip initialization for VGA_NONE
2. remove the useless 'break'

f0c3c505a8 cpu: Move breakpoints field from CPU_COMMON to CPUState
Most targets were using offsetof(CPUFooState, breakpoints) to determine
how much of CPUFooState to clear on reset. Use the next field after
CPU_COMMON instead, if any, or sizeof(CPUFooState) otherwise.
