72b3b8f24a target/xtensa: tests: fix timer tests
Don't expect that CCOUNT increments are equal to the number of executed
instructions. Verify that timer interrupt does not fire before the
programmed CCOMPARE value and does fire after.

204febd17f libqtest: handle zero length memwrite/memread
Some recently added tests pass a zero length to qtest_memwrite().
Unfortunately, the qtest protocol doesn't implement an on-the-wire
syntax for zero-length writes and the current code happily sends
garbage to QEMU. This causes intermittent failures.

It isn't worth the pain to enhance the protocol, so this patch
simply fixes the issue by "just return, doing nothing". The same
fix is applied to qtest_memread() since the issue also exists in
the QEMU part of the "memread" command.

a37c07022b tests: virtio-9p: ".." cannot be used to walk out of the shared directory
According to the 9P spec at http://man.cat-v.org/plan_9/5/intro, the
parent directory of the root directory of a server's tree is itself.
This test hence checks that the qid of the root directory as returned by
attach is the same as the qid of ".." when walking from the root directory.

The walk operation is used to traverse the directory tree and to associate
paths to fids. A single walk can be used to traverse up to P9_MAXWELEM path
elements at the same time.

The test creates a path with P9_MAXWELEM elements on the backend (à la
'mkdir -p') and issues a walk operation. The walk is expected to succeed
without error.

6cc9906b4c tests: virtio-9p: add version operation test
This patch lays the foundations to be able to test 9P operations and
provides a test for the version operation as a first example.

A 9P request is composed of a T-message sent by the client (guest) to the
server (QEMU), and a R-message sent by the server back to the client.

The following general calls are available to implement requests for any
9P operations:

v9fs_req_init(): allocates the request structure and the guest memory for
                 the T-message

v9fs_req_send(): allocates the guest memory for the R-message and sends the
                 T-message to QEMU

v9fs_req_recv(): waits for QEMU to answer and does some sanity checks on the
                 returned R-message header

v9fs_req_free(): releases the guest memory and the request structure

Helpers are provided, to be used by each specific 9P operation to copy data
to/from the guest memory.

The version operation is used to negotiate the 9P protocol version to be
used and the maximum buffer size for exchanged data. It is necessarily
the first message of a 9P session. For simplicity, the maximum buffer size
is hardcoded to 4k, which should be enough for functional tests.

The test simply advertises the "9P2000.L" version to QEMU and expects QEMU
to answer it is supported.

fcf5ef2ab5 Move target-* CPU file into a target/ folder
We've currently got 18 architectures in QEMU, and thus 18 target-xxx
folders in the root folder of the QEMU source tree. More architectures
(e.g. RISC-V, AVR) are likely to be included soon, too, so the main
folder of the QEMU sources slowly gets quite overcrowded with the
target-xxx folders.
To disburden the main folder a little bit, let's move the target-xxx
folders into a dedicated target/ folder, so that target-xxx/ simply
becomes target/xxx/ instead.

a3e1505dae qcow2: Don't strand clusters near 2G intervals during commit
The qcow2_make_empty() function is reached during 'qemu-img commit',
in order to clear out ALL clusters of an image.  However, if the
image cannot use the fast code path (true if the image is format
0.10, or if the image contains a snapshot), the cluster size is
larger than 512, and the image is larger than 2G in size, then our
choice of sector_step causes problems.  Since it is not cluster
aligned, but qcow2_discard_clusters() silently ignores an unaligned
head or tail, we are leaving clusters allocated.

Enhance the testsuite to expose the flaw, and patch the problem by
ensuring our step size is aligned.

29a6731afb tests: Avoid qobject_from_jsonf("%"PRId64)
The qobject_from_jsonf() function implements a pseudo-printf
language for creating a QObject; however, it is hard-coded to
only parse a subset of formats understood by -Wformat, and is
not a straight synonym to bare printf().  In particular, any
use of an int64_t integer works only if the system's
definition of PRId64 matches what the parser expects; which
works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd).  Rather than enhance
the parser, it is just as easy to force the use of int (where
the value is small enough) or long long instead of int64_t,
which we know always works.

This should cover all remaining testsuite uses of
qobject_from_json[fv]() that were trying to rely on PRId64,
although my proof for that was done by adding in asserts and
checking that 'make check' still passed, where such asserts
are inappropriate during hard freeze.  A later series in 2.9
may remove all dynamic JSON parsing, but that's a bigger task.

1792d7d0a2 test-qga: Avoid qobject_from_jsonv("%"PRId64)
The qobject_from_jsonv() function implements a pseudo-printf
language for creating a QObject; however, it is hard-coded to
only parse a subset of formats understood by -Wformat, and is
not a straight synonym to bare printf().  In particular, any
use of an int64_t integer works only if the system's
definition of PRId64 matches what the parser expects; which
works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd).  Rather than enhance
the parser, it is just as easy to use normal printf() for
this particular conversion, matching what is done elsewhere
in this file [1], which is safe in this instance because the
format does not contain any of the problematic differences
(bare '%' or the '%s' format).

The use of PRId64 for a variable named 'pid' is gross, but it
is a sad reality of the 64-bit mingw environment, which
mistakenly defines pid_t as a 64-bit type even though getpid()
returns 'int' on that platform [2].  Our definition of the
QGA GuestExec type defines 'pid' as a 64-bit entity, and we
can't tighten it to 'int32' unless the mingw header is fixed.
Using 'long long' instead of 'int64_t' just so that we can
stick with qobject_from_jsonv("%lld") instead of printf() is
not any prettier, since we may have later type churn anyways.

171da9d5db tests/postcopy: Use KVM on ppc64 only if it is KVM-HV
The ppc64 postcopy test does not work with KVM-PR, and it is also
causing annoying warning messages when run on a x86 host. So let's
use KVM here only if we know that we're running with KVM-HV (which
automatically also means that we're running on a ppc64 host), and
fall back to TCG otherwise.

For now, add the block_job_start mechanism and start the jobs
automatically as we have been doing, with conversions job-by-job coming
in later patches.

Of note: cancellation of unstarted jobs will perform all the normal
cleanup as if the job had started, particularly abort and clean. The
only difference is that we will not emit any events, because the job
never actually started.

ebde93bf9a ahci-test: test atapi read_cd with bcl, nb_sectors = 0
Commit 9ef2e93f introduced the concept of tagging ATAPI commands as
NONDATA, but this introduced a regression for certain commands better
described as CONDDATA. read_cd is such a command that both requires
a non-zero BCL if a transfer size is set, but is perfectly content to
accept a zero BCL if the transfer size is 0.

This test adds a regression test for the case where BCL and nb_sectors
are both 0.

Flesh out the CDROM tests by:

(1) Allowing the test to specify a BCL
(2) Allowing the buffer comparison test to compare a 0-size buffer
(3) Fix the BCL specification in libqos (It is LE, not BE)
(4) Add a nice human-readable message for future SCSI command additions

e6af1e0854 block: Don't mark node clean after failed flush
Commit 3ff2f67a changed bdrv_co_flush() so that no flush is issues if
the image hasn't been dirtied since the last flush. This is not quite
correct: The condition should be that the image hasn't been dirtied
since the last _successful_ flush. This patch changes the logic
accordingly.

Without this fix, subsequent bdrv_co_flush() calls would return success
without actually doing anything even though the image is still dirty.
The difference is visible in some blkdebug test cases where error
messages incorrectly disappeared after commit 3ff2f67a.

f53b9f3625 ipmi: Add graceful shutdown handling to the external BMC
I misunderstood the workings of the power settings, the power off
is a force off operation and there needs to be a separate graceful
shutdown operation.  So replace the force off operation with a

c87621ea68 blockjobs: split interface into public/private, Part 1
To make it a little more obvious which functions are intended to be
public interface and which are intended to be for use only by jobs
themselves, split the interface into "public" and "private" files.

Convert blockjobs (e.g. block/backup) to using the private interface.
Leave blockdev and others on the public interface.

There are remaining uses of private state by qemu-img, and several
cases in blockdev.c and block/io.c where we grab job->blk for the
purposes of acquiring an AIOContext.

These will be corrected in future patches.

66a77ea676 ppc patch queue 2016-10-28
This pull request supersedes and extends the one from 2016-10-26
 (which had a build bug).
 
 Highlights:
   * SLOF (pseries guest firmware) update
   * Enable a number of extra testcases on ppc / pseries
   * Added the 'powernv' machine type
     - Almost enough to be minimally usable
     - But still missing necessary interrupt controller updates
   * Cleanup and consolidation of NVRAM handling on several platforms
     with related firmware
   * Substantial cleanup to device tree construction
   * Some more POWER9 instruction emulation
   * Cleanup to handling of pseries option vectors and CAS reboot
     handling (host/guest feature negotiation mechanism)
   * Significant cleanups to handling of PCI devices in test cases
   * New hotplug event infrastructure
   * Memory hot unplug support for pseries
   * Several bug fixes
 
 The NVRAM cleanup affects some Sun sparc platforms as well as ppc
 ones, but have been tested by the sparc maintainer (Mark Cave-Ayland).
 
 The test additions also include substantial general changes to the
 test framework that aren't strictly ppc related.  They don't seem to
 break tests on other platforms, they're for the benefit of enabling
 tests on ppc and there isn't a specific maintainer for them, so
 they're included in this tree.

65c1b5b622 iothread: release AioContext around aio_poll
This is the first step towards having fine-grained critical sections in
dataplane threads, which will resolve lock ordering problems between
address_space_* functions (which need the BQL when doing MMIO, even
after we complete RCU-based dispatch) and the AioContext.

Because AioContext does not use contention callbacks anymore, the
unit test has to be changed.

Now that we also support the "-prom-env" parameter for the pseries
machine, we can enable this test for this machine, too. Since booting
with TCG is rather slow with the pseries machine, we also enable
the "-nodefaults" parameter for this test now, so that SLOF does not
have to check that much devices during boot and thus runs a little

b4ba67d9a7 libqos: Change PCI accessors to take opaque BAR handle
The usual use model for the libqos PCI functions is to map a specific PCI
BAR using qpci_iomap() then pass the returned token into IO accessor
functions.  This, and the fact that iomap() returns a (void *) which
actually contains a PCI space address, kind of suggests that the return
value from iomap is supposed to be an opaque token.

..except that the callers expect to be able to add offsets to it.  Which
also assumes the compiler will support pointer arithmetic on a (void *),
and treat it as working with byte offsets.

To clarify this situation change iomap() and the IO accessors to take
a definitely opaque BAR handle (enforced with a wrapper struct) along with
an offset within the BAR.  This changes both the functions and all the
callers.

There were a number of places that checked if iomap() returned non-NULL,
and or initialized it to NULL before hand.  Since iomap() already assert()s
if it fails to map the BAR, these tests were mostly pointless and are
removed.

e7c8526b2a tests: Don't assume structure of PCI IO base in ahci-test
In a couple of places ahci-test makes assumptions about how the tokens
returned from qpci_iomap() are formatted in ways it probably shouldn't.

First in verify_state() it uses a non-NULL token to indicate that the AHCI
device has been enabled (part of enabling is to iomap()).  This changes it
to use an explicit 'enabled' flag instead.

Second, it uses the fact that the token contains a PCI address, stored when
the BAR is mapped during initialization to check that the BAR has the same
value after a migration.  This changes it to explicitly read the BAR
register before and after the migration and compare.

Together, these changes will  make the test more robust against changes to
the internals of the libqos PCI layer.

204e54b86d tests: Use qpci_mem{read,write} in ivshmem-test
ivshmem implements a block of shared memory in a PCI BAR.  Currently our
test case accesses this using qtest_mem{read,write}.  However, deducing
the correct addresses for these requires making assumptions about the
internel format returned by qpci_iomap(), along with some ugly casts.

This patch changes the test to use the new qpci_mem{read,write} interfaces
which is neater.

f775f45ab8 libqos: Add 64-bit PCI IO accessors
Currently the libqos PCI layer includes accessor helpers for 8, 16 and 32
bit reads and writes.  It's likely that we'll want 64-bit accesses in the
future (plenty of modern peripherals will have 64-bit reigsters).  This
adds them.

For PIO (not MMIO) accesses on the PC backend, this is implemented as two
32-bit ins or outs.  That's not ideal but AFAICT x86 doesn't have 64-bit
versions of in and out.

This patch also converts the single current user of 64-bit accesses -
virtio-pci.c to use the new mechanism, rather than a sequence of 8 byte
reads.

352d664cce libqos: Implement mmio accessors in terms of mem{read,write}
In the libqos PCI code we now have accessors both for registers (byte
significance preserving) and for streaming data (byte address order
preserving).  These exist in both the interface for qtest drivers and in
the machine specific backends.

However, the register-style accessors aren't actually necessary in the
backend.  They can be implemented in terms of the byte address order
preserving accessors by the libqos wrappers.  This works because PCI is
always little endian.

This does assume that the back end byte address order preserving accessors
will perform the equivalent of a single bus transaction for short lengths.
This is the case, and in fact they currently end up using the same
cpu_physical_memory_rw() implementation within the qtest accelerator.

a certain size.  However, there are a few cases where we instead need a
"bag of bytes" style streaming interface to PCI MMIO space.  This can be
either for streaming data style registers or when there's actual memory
rather than registers in PCI space, for example frame buffers or ivshmem.

This patch adds backend callbacks, and libqos wrappers for this type of
byte address order preserving accesses.

a7b85b6062 libqos: Better handling of PCI legacy IO
The usual model for PCI IO with libqos is to use qpci_iomap() to map a
specific BAR for a PCI device, then perform IOs within that BAR using
qpci_io_{read,write}*().

However, certain devices also have legacy PCI IO.  In this case, instead of
(or as well as) being accessed via PCI BARs, the device can be accessed
via certain well-known, fixed addresses in PCI IO space.

Two existing tests use legacy PCI IO, and take different flawed approaches
to it:
    * tco-test manually constructs a tco_io_base value instead of calling
      qpci_iomap(), which assumes internal knowledge of the structure of
      the value it shouldn't have
    * ide-test uses direct in*() and out*() calls instead of using
      qpci_io_*() accessors, meaning it's not portable to non-x86 machine
      types.

This patch implements a new qpci_iomap_legacy() interface which gets a
handle in the same format as qpci_iomap() but refers to a region in
the legacy PIO space.  For a device which has the same registers
available both in a BAR and in legacy space (quite common), this
allows the same test code to test both options with just a different
iomap() at the beginning.

b8cc4d0231 libqos: Move BAR assignment to common code
The PCI backends in libqos each supply an iomap() and iounmap() function
which is used to set up a specified PCI BAR.  But PCI BAR allocation takes
place entirely within PCI space, so doesn't really need per-backend
versions.  For example, Linux includes generic BAR allocation code used on
platforms where that isn't done by firmware.

This patch merges the BAR allocation from the two existing backends into a
single simplified copy.  The back ends just need to set up some parameters
describing the window of PCI IO and PCI memory addresses which are
available for allocation.  Like both the existing versions the new one uses
a simple bump allocator.

Note that (again like the existing versions) this doesn't really handle
64-bit memory BARs properly.  It is actually used for such a BAR by the
ivshmem test, and apparently the 32-bit MMIO BAR logic is close enough to
work, as long as the BAR isn't too big.  Fixing that to properly handle
64-bit BAR allocation is a problem for another time.

a795fc08f2 libqos: Handle PCI IO de-multiplexing in common code
The PCI IO space (aka PIO, aka legacy IO) and PCI memory space (aka MMIO)
are distinct address spaces by the PCI spec (although parts of one might be
aliased to parts of the other in some cases).

However, qpci_io_read*() and qpci_io_write*() can perform accesses to
either space depending on parameter.  That's convenient for test case
drivers, since there are a fair few devices which can be controlled via
either a PIO or MMIO BAR but with an otherwise identical driver.

This is implemented by having addresses below 64kiB treated as PIO, and
those above treated as MMIO.  This works because low addresses in memory
space are generally reserved for DMA rather than MMIO.

At the moment, this demultiplexing must be handled by each PCI backend
(pc and spapr, so far).  There's no real reason for this - the current
encoding is likely to work for all platforms, and even if it doesn't we
can still use a more complex common encoding since the value returned from
iomap are semi-opaque.

This patch moves the demultiplexing into the common part of the libqos PCI
code, with the backends having simpler, separate accessors for PIO and
MMIO space.  This also means we have a way of explicitly accessing either
space if it's necessary for some special case.

246fc0fb66 libqos: Give qvirtio_config_read*() consistent semantics
The 'addr' parameter to qvirtio_config_read*() doesn't have a consistent
meaning: when using the virtio-pci versions, it's a full PCI space address,
but for virtio-mmio, it's an offset from the device's base mmio address.

This means that the callers need to do different things to calculate the
addresses in the two cases, which rather defeats the purpose of function
pointer backends.

All the current users of these functions are using them to retrieve
variables from the device specific portion of the virtio config space.
So, this patch alters the semantics to always be an offset into that
device specific config area.

However, this doesn't make anything work that was broken before: The
only way to get IMGOPTSSYNTAX is with -luks, but the combination of
-luks and -nfs doesn't get qemu-img create commands right (because
qemu-img create doesn't support --image-opts yet), so even after this

603476c25c qdict: implement a qdict_crumple method for un-flattening a dict
The qdict_flatten() method will take a dict whose elements are
further nested dicts/lists and flatten them by concatenating
keys.

The qdict_crumple() method aims to do the reverse, taking a flat
qdict, and turning it into a set of nested dicts/lists. It will
apply nesting based on the key name, with a '.' indicating a
new level in the hierarchy. If the keys in the nested structure
are all numeric, it will create a list, otherwise it will create
a dict.

If the keys are a mixture of numeric and non-numeric, or the
numeric keys are not in strictly ascending order, an error will
be reported.

As an example, a flat dict containing

 {
   'foo.0.bar': 'one',
   'foo.0.wizz': '1',
   'foo.1.bar': 'two',
   'foo.1.wizz': '2'
 }

will get turned into a dict with one element 'foo' whose
value is a list. The list elements will each in turn be
dicts.

 {
   'foo': [
     { 'bar': 'one', 'wizz': '1' },
     { 'bar': 'two', 'wizz': '2' }
   ],
 }

If the key is intended to contain a literal '.', then it must
be escaped as '..'. ie a flat dict

  {
     'foo..bar': 'wizz',
     'bar.foo..bar': 'eek',
     'bar.hello': 'world'
  }

Will end up as

  {
     'foo.bar': 'wizz',
     'bar': {
        'foo.bar': 'eek',
        'hello': 'world'
     }
  }

The intent of this function is that it allows a set of QemuOpts
to be turned into a nested data structure that mirrors the nesting
used when the same object is defined over QMP.

12ac9d9e90 iotests: Do not rely on unavailable domains in 162
There are some (mostly ISP-specific) name servers who will redirect
non-existing domains to special hosts. In this case, we will get a
different error message when trying to connect to such a host, which
breaks test 162.

162 needed this specific error message so it can confirm that qemu was
indeed trying to connect to the user-specified port. However, we can
also confirm this by setting up a local NBD server on exactly that port;
so we can fix the issue by doing just that.

a26ddb4396 qemu-iotests: Test I/O in a single drive from a throttling group
iotest 093 contains a test that creates a throttling group with
several drives and performs I/O in all of them. This patch adds a new
test that creates a similar setup but only performs I/O in one of the
drives at the same time.

This is useful to test that the round robin algorithm is behaving
properly in these scenarios, and is specifically written using the
regression introduced in 27ccdd5259 as an example.

0153d2f50b block: Remove "options" indirection from blockdev-add
Now that QAPI supports boxed types, we can have unions at the top level
of a command, so let's put our real options directly there for
blockdev-add instead of having a single "options" dict that contains the
real arguments.

blockdev-add is still experimental and we already made substantial
changes to the API recently, so we're free to make changes like this
one, too.

     * A number of extra tests added for ppc
     * Other tests clean up / fixed
     * Some cleanups to the XICS interrupt controller in preparation
       for the 'powernv' machine type
 
 A number of the test changes aren't strictly in ppc related code, but
 are included via my tree because they're primarily focused on
 improving test coverage for ppc.

Merge remote-tracking branch 'remotes/dgibson/tags/ppc-for-2.8-20161017' into staging

ppc patch queue 2016-10-17

Highlights:
    * Significant rework of how PCI IO windows are placed for the
      pseries machine type
    * A number of extra tests added for ppc
    * Other tests clean up / fixed
    * Some cleanups to the XICS interrupt controller in preparation
      for the 'powernv' machine type

A number of the test changes aren't strictly in ppc related code, but
are included via my tree because they're primarily focused on
improving test coverage for ppc.

e86c9a64f4 tests/docker/Makefile.include: add a generic docker-run target
This re-factors the docker makefile to include a docker-run target which
can be controlled entirely from environment variables specified on the
make command line. This allows us to run against any given docker image
we may have in our repository, for example:

    make docker-run TEST="test-quick" IMAGE="debian:arm64" \
         EXECUTABLE=./aarch64-linux-user/qemu-aarch64

The existing docker-foo@bar targets still work but the inline
verification has been dropped because we already don't hit that due to
other pattern rules in rules.mak.

357d1e3bc7 spapr: Improved placement of PCI host bridges in guest memory map
Currently, the MMIO space for accessing PCI on pseries guests begins at
1 TiB in guest address space.  Each PCI host bridge (PHB) has a 64 GiB
chunk of address space in which it places its outbound PIO and 32-bit and
64-bit MMIO windows.

This scheme as several problems:
  - It limits guest RAM to 1 TiB (though we have a limited fix for this
    now)
  - It limits the total MMIO window to 64 GiB.  This is not always enough
    for some of the large nVidia GPGPU cards
  - Putting all the windows into a single 64 GiB area means that naturally
    aligning things within there will waste more address space.
In addition there was a miscalculation in some of the defaults, which meant
that the MMIO windows for each PHB actually slightly overran the 64 GiB
region for that PHB.  We got away without nasty consequences because
the overrun fit within an unused area at the beginning of the next PHB's
region, but it's not pretty.

This patch implements a new scheme which addresses those problems, and is
also closer to what bare metal hardware and pHyp guests generally use.

Because some guest versions (including most current distro kernels) can't
access PCI MMIO above 64 TiB, we put all the PCI windows between 32 TiB and
64 TiB.  This is broken into 1 TiB chunks.  The first 1 TiB contains the
PIO (64 kiB) and 32-bit MMIO (2 GiB) windows for all of the PHBs.  Each
subsequent TiB chunk contains a naturally aligned 64-bit MMIO window for
one PHB each.

This reduces the number of allowed PHBs (without full manual configuration
of all the windows) from 256 to 31, but this should still be plenty in
practice.

We also change some of the default window sizes for manually configured
PHBs to saner values.

Finally we adjust some tests and libqos so that it correctly uses the new
default locations.  Ideally it would parse the device tree given to the
guest, but that's a more complex problem for another time.

8360544a6d libqos: Limit spapr-pci to 32-bit MMIO for now
Currently the functions in pci-spapr.c (like pci-pc.c on which it's based)
don't distinguish between 32-bit and 64-bit PCI MMIO.  At the moment, the
qemu side implementation is a bit weird and has a single MMIO window
straddling 32-bit and 64-bit regions, but we're likely to change that in
future.

In any case, pci-pc.c - and therefore the testcases using PCI - only handle
32-bit MMIOs for now.  For spapr despite whatever changes might happen with
the MMIO windows, the 32-bit window is likely to remain at 2..4 GiB in PCI
space.

So, explicitly limit pci-spapr.c to 32-bit MMIOs for now, we can add 64-bit
MMIO support back in when and if we need it.

c711369087 libqos: Correct error in PCI hole sizing for spapr
In pci-spapr.c (as in pci-pc.c from which it was derived), the
pci_hole_start/pci_hole_size and pci_iohole_start/pci_iohole_size pairs[1]
essentially define the region of PCI (not CPU) addresses in which MMIO
or PIO BARs respectively will be allocated.

The size value is relative to the start value.  But in pci-spapr.c it is
set to the entire size of the window supported by the (emulated) hardware,
but the start values are *not* at the beginning of the emulated windows.

That means if you tried to map enough PCI BARs, we'd messily overrun the
IO windows, instead of failing in iomap as we should.

This patch corrects this by calculating the hole sizes from the location
of the window in PCI space and the hole start.

[1] Those are bad names, but that's a problem for another time.

cd1b354ec0 libqos: Isolate knowledge of spapr memory map to qpci_init_spapr()
The libqos code for accessing PCI on the spapr machine type uses IOBASE()
and MMIOBASE() macros to determine the address in the CPU memory map of
the windows to PCI address space.

This is a detail of the implementation of PCI in the machine type, it's not
specified by the PAPR standard.  Real guests would get the addresses of the
PCI windows from the device tree.

Finding the device tree in libqos would be awkward, but we can at least
localize this knowledge of the implementation to the init function, saving
it in the QPCIBusSPAPR structure for use by the accessors.

That leaves only one place to fix if we alter the location of the PCI
windows, as we're planning to do.

74cba2b3b2 tests/boot-sector: Increase time-out to 90 seconds
Since the PXE tester runs rather slow on ppc64 with tcg, there
is a chance that we hit the 60 seconds timeout on machines that
have a heavy CPU load. So let's increase the timeout to ease
the situation.

3e35377372 tests/boot-sector: Use mkstemp() to create a unique file name
The pxe-test is run for three different targets now (x86_64, i386
and ppc64), and the bios-tables-test is run for two targets (x86_64
and i386). But each of the tests is using an invariant name for the
disk image with the boot sector code - so if the tests are running in
parallel, there is a race condition that they destroy the disk image
of a parallel test program. Let's use mkstemp() to create unique
temporary files here instead - and since mkstemp() is returning an
integer file descriptor instead of a FILE pointer, we also switch
the fwrite() and fclose() to write() and close() instead.

qht_lookup is meant to be called from an RCU read-critical
section. Make sure we're in such a section in test-qht
when performing lookups, despite the fact that no races
in qht can be triggered by test-qht since it is single-threaded.

Note that rcu_register_thread is already called by the
rcu_after_fork hook, and therefore duplicating it here would
be a bug.

0bdb12c7c5 rules.mak: quiet-command: Split command name and args to print
The quiet-command make rule currently takes two arguments:
the command and arguments to run, and a string to print if
the V flag is not set (ie we are not being verbose).
By convention, the string printed is of the form
"  NAME   some args". Unfortunately to get nicely lined up
output all the strings have to agree about what column the
arguments should start in, which means that if we add a
new quiet-command usage which wants a slightly longer CMD
name then we either put up with misalignment or change
every quiet-command string.

Split the quiet-mode string into two, the "NAME" and
the "same args" part, and use printf(1) to format the
string automatically. This means we only need to change
one place if we want to support a longer maximum name.

In particular, we can now print 7-character names lined
up properly (they are needed for the OSX "SETTOOL" invocation).

Change all the uses of quiet-command to the new syntax.
(Any which are missed or inadvertently reintroduced
via later merges will result in slightly misformatted
quiet output rather than disaster.)

A few places in the pc-bios/ makefiles are updated to use
"BUILD", "SIGN" and "STRIP" rather than "Building",
"Signing" and "Stripping" for consistency and to keep them
below 7 characters. Module .mo links now print "LD" rather
than the nonstandard "LD -r".

ef6c47f1d7 tests/pxe: Use -nodefaults to speed up ppc64/ipv6 pxe test
SLOF is unfortunately quite slow when running with TCG, so
the pxe test is also performing rather slow here. By using
"-nodefaults" we can disable some devices (vscsi) that we
are not interested in here, so that SLOF does not have to
scan them during boot and thus starts up a little bit faster.
The ppc64 pxe-test now only takes 27 seconds on my laptop
instead of 33 seconds.
The "-nodefaults" flag seems to work fine for the x86 tests,
too, so it is added here unconditionally here (though there
is no speed-up on x86 by using this flag).

The firmware of the pseries machine, SLOF, is able to load files via
IPv6 networking, too. So to test both, network bootloading on ppc64
and IPv6 (via Slirp) , let's add some PXE tests for this environment,
too. Since we can not use the normal x86 boot sector for network boot
loading, we use a simple Forth script on ppc64 instead.

0a4279d97c block/qapi: Move 'aio' option to file driver
The option whether or not to use a native AIO interface really isn't a
generic option for all drivers, but only applies to the native file
protocols. This patch moves the option in blockdev-add to the
appropriate places (raw-posix and raw-win32).

We still have to keep the flag BDRV_O_NATIVE_AIO for compatibility
because so far the AIO option was usually specified on the wrong layer
(the top-level format driver, which didn't even look at it) and then
inherited by the protocol driver (where it was actually used). We can't
forbid this use except in new interfaces.

Add the appropriate register constraints for the inline asm for the
write and exit system calls.  Without the correct constraints for the

SVM needs CPUID[0x8000000A] to be available. So if SVM is enabled
in a CPU model or explicitly in the command-line, adjust CPUID
xlevel to expose the CPUID[0x8000000A] leaf.

c39c0edf9b target-i386: Automatically set level/xlevel/xlevel2 when needed
Instead of requiring users and management software to be aware of
required CPUID level/xlevel/xlevel2 values for each feature,
automatically increase those values when features need them.

This was already done for CPUID[7].EBX, and is now made generic
for all CPUID feature flags. Unit test included, to make sure we
don't break ABI on older machine-types and don't mess with the
CPUID level values if they are explicitly set by the user.

This pull request supersedes ppc-for-2.8-20160922.  There was a clang
 build error in that, and I've also added one extra patch in the new pull.
 
 Included in this set of ppc and spapr patches are:
     * TCG implementations for more POWER9 instructions
     * Some preliminary XICS fixes in preparataion for the pnv machine type
     * A significant ADB (Macintosh kbd/mouse) cleanup
     * Some conversions to use trace instead of debug macros
     * Fixes to correctly handle global TLB flush synchronization in
       TCG.  This is already a bug, but it will have much more impact
       when we get MTTCG
     * Add more qtest testcases for Power
     * Some MAINTAINERS updates
     * Assorted bugfixes
     * Add the basics of NUMA associativity to the spapr PCI host bridge
 
 This touches some test files and monitor.c which are technically
 outside the ppc code, but coming through this tree because the changes
 are primarily of interest to ppc.

creates a BDS, but no BB. Consequently, x-blockdev-del doesn't need the
'device' option any more, but 'node-name' becomes mandatory.

486b88bdc8 qemu-iotests/118: Test media change with qdev name
We just added the option to use qdev device names in all device related
block QMP commands. This patch converts some of the test cases in 118 to
use qdev device names instead of BlockBackend names to cover the new
way. It converts cases for each of the media change commands, but only
for CD-ROM and not everywhere, so that the old way is still tested, too.

bb9f8dd0e1 qcow2: fix encryption during cow of sectors
Broken in previous commit:

  commit aaa4d20b49
  Author: Kevin Wolf <kwolf@redhat.com>
  Date:   Wed Jun 1 15:21:05 2016 +0200

      qcow2: Make copy_sectors() byte based

The copy_sectors() code was originally using the 'sector'
parameter for encryption, which was passed in by the caller
from the QCowL2Meta.offset field (aka the guest logical
offset).

After the change, the code is using 'cluster_offset' which
was passed in from QCow2L2Meta.alloc_offset field (aka the
host physical offset).

This would cause the data to be encrypted using an incorrect
initialization vector which will in turn cause later reads
to return garbage.

Although current qcow2 built-in encryption is blocked from
usage in the emulator, one could still hit this if writing
to the file via qemu-{img,io,nbd} commands.

For the start, this implements the bs, if, of and count options and requires
both if and of to be specified (no stdin/stdout if not specified) and doesn't
support tty, pipes, etc.

The image format must be specified with -O for the output if the raw format
is not the intended one.

a0067da157 qapi: check invalid arguments on no-args commands
The generated marshal functions do not visit arguments from commands
that take no arguments. Thus they fail to catch invalid
members. Visit the arguments, if provided, to throw an error in case of
invalid members.

Currently, qmp_check_client_args() checks for invalid arguments and
correctly catches this case. When switching to qmp_dispatch() we want to
keep that behaviour. The commands using 'O' may have arbitrary
arguments, and must have 'gen': false in the qapi schema to skip the
generated checks.

Old/new diff:
 void qmp_marshal_stop(QDict *args, QObject **ret, Error **errp)
 {
     Error *err = NULL;
+    Visitor *v = NULL;

-    (void)args;
+    if (args) {
+        v = qmp_input_visitor_new(QOBJECT(args), true);
+        visit_start_struct(v, NULL, NULL, 0, &err);
+        if (err) {
+            goto out;
+        }
+
+        if (!err) {
+            visit_check_struct(v, &err);
+        }
+        visit_end_struct(v, NULL);
+        if (err) {
+            goto out;
+        }
+    }

     qmp_stop(&err);
+
+out:
     error_propagate(errp, err);
+    visit_free(v);
+    if (args) {
+        v = qapi_dealloc_visitor_new();
+        visit_start_struct(v, NULL, NULL, 0, NULL);
+
+        visit_end_struct(v, NULL);
+        visit_free(v);
+    }
 }

The new code closely resembles code for a command with arguments.
Differences:
- the visit of the argument and its cleanup struct don't visit any
  members (because there are none).

Daniel P. Berrange
e74aabcffb crypto: use correct derived key size when timing pbkdf
Currently when timing the pbkdf algorithm a fixed key
size of 32 bytes is used. This results in inaccurate
timings for certain hashes depending on their digest
size. For example when using sha1 with aes-256, this
causes us to measure time for the master key digest
doing 2 sha1 operations per iteration, instead of 1.

Instead we should pass in the desired key size to the
timing routine that matches the key size that will be
used for real later.

d9269b274a crypto: fix building complaint
gnutls commit 846753877d renamed LIBGNUTLS_VERSION_NUMBER to GNUTLS_VERSION_NUMBER.
If using gnutls before that verion, we'll get the below warning:
crypto/tlscredsx509.c:618:5: warning: "GNUTLS_VERSION_NUMBER" is not defined

Because gnutls 3.x still defines LIBGNUTLS_VERSION_NUMBER for back compat, Let's
use LIBGNUTLS_VERSION_NUMBER instead of GNUTLS_VERSION_NUMBER to fix building
complaint.

a5d2f44d0d crypto: ensure XTS is only used with ciphers with 16 byte blocks
The XTS cipher mode needs to be used with a cipher which has
a block size of 16 bytes. If a mis-matching block size is used,
the code will either corrupt memory beyond the IV array, or
not fully encrypt/decrypt the IV.

This fixes a memory corruption crash when attempting to use
cast5-128 with xts, since the former has an 8 byte block size.

A test case is added to ensure the cipher creation fails with
such an invalid combination.

 queued for a while.  In particular:
     * A number of preliminary patches for the powernv machine type
         * A substantial cleanup of exception handling which will be
           necessary to support running a TCG with hypervisor
           facilities
     * A start on support for POWER9
         * Some TCG implementations for new POWER9 instructions
         * Some TCG and related cleanups in preparation for POWER9
     * Some assorted TCG optimizations
     * An implementation of the H_CHANGE_LOGICAL_LAN_MAC hypercall
       which allows the MAC address to be changed on the PAPR virtual
       NIC.
     * Add some extra test cases for several machines (this isn't
       strictly in the ppc code, but is most value to ppc)
 
 NOTE: This pull request supersedes ppc-for-2.8-20160906, which had
 some problems.  Changes:
   * Dropped BenH's lmw/stmw speedups, which break for
     qemu-system-ppc64 on BE hosts
   * A small fix to Thomas' serial output test to avoid a warning on
     the isapc machine type.
   * Some trivial checkpatch fixes
 
 Note that some of the patches in this series still have large numbers
 of checkpatch warnings.  This is because they're moving existing code
 that predates most of the checkpatch style conventions.

Some of the machines that we have got a firmware image for write

29531542bc tests: Resort check-qtest entries in Makefile.include
The rather random list of check-qtest-xxx entries caused some
confusion in the past, where to use "=" and where to use "+="
(see commits 0ccac16f59 and 1f5c1cfbae
for example).
Sorting the check-qtest-xxx entries by architecure instead and
using some empty lines inbetween should help to ease this
situation a little bit, so that it is hopefully now obvious
that new tests should be added with "+=" instead of "=".
While we are at it, this patch also comments out two of the
"gcov-files-..." lines since the corresponding m48t59-test is
disabled for sparc and sparc64, too.

cdafe92961 vhost-user-test: Use libqos instead of pxe-virtio.rom
vhost-user-test relies on iPXE just to initialize the virtio-net
device, and doesn't do any actual packet tx/rx testing.

In addition to that, the test relies on TCG, which is
imcompatible with vhost. The test only worked by accident: a bug
the memory backend initialization made memory regions not have
the DIRTY_MEMORY_CODE bit set in dirty_log_mask.

This changes vhost-user-test to initialize the virtio-net device
using libqos, and not use TCG nor pxe-virtio.rom.

980e66216f test-coroutine: Fix coroutine pool corruption
The test case overwrites the Coroutine object with 0xff as a way to
assert that the coroutine isn't used any more. However, this means that
the coroutine pool now contains a corrupted object and later test cases
may get this corrupted object and crash.

This patch saves the real content of the object and restores it after
completing the test. The only use of the coroutine pool between those
two points is the deletion of co2. As this only means an insertion at
the head of an SLIST (release_pool or alloc_pool), it doesn't access the
invalid list pointers that co1 has during this period.

5f9f818ea8 test-logging: don't hard-code paths in /tmp
Since f6880b7f [qemu-log: support simple pid substitution for logs],
test-logging creates files with hard-coded names in /tmp. In the best
case, this prevents multiple developers from running "make check" on
the same machine. In the worst case, it allows for symlink attacks,
enabling an attacker to overwrite files that are writable to the
developer running "make check".

Instead of hard-coding the paths, create a temporary directory using
g_dir_make_tmp() and clean it up afterwards.

3fdd0ee393 timer: set vm_clock disabled default
(commit 80dcfb8532)
Upon migration, the code use a timer based on vm_clock for 1ns
in the future from post_load to do the event send in case host_connected
differs between migration source and target.

However, it's not guaranteed that the apic is ready to inject irqs into
the guest, and the irq line remained high, resulting in any future interrupts
going unnoticed by the guest as well.

That's because 1) the migration coroutine is not blocked when it get EAGAIN
while reading QEMUFile. 2) The vm_clock is enabled default currently, it doesn't
rely on the calling of vm_start(), that means vm_clock timers can run before
VCPUs are running.

So, let's set the vm_clock disabled default, keep the initial intention of
design for vm_clock timers.

Meanwhile, change the test-aio usecase, using QEMU_CLOCK_REALTIME instead of
QEMU_CLOCK_VIRTUAL as the block code does.

a752e4786c iotests: fix 109
109 iotest is broken for raw after 0965a41e99
[mirror: double performance of the bulk stage if the disc is full]

The problem is with finishing block-job with error: before specified
patch mirror was not very async and it created one big request at disk
start, this request finished with error and qemu produced
BLOCK_JOB_COMPLETED with zero progress.

After 0965a41, mirror starts several smaller requests in parallel, when
BLOCK_JOB_COMPLETED emited we have some successful non-zero progress.

This patch solves the issue by filtering out progress from 109 test
output.

51009170d8 tests: Rename qtests which have names ending "error"
We have three qtest tests which have test names ending with "error".
This is awkward because the output of verbose test runs looks like
  /crypto/task/error:                                                  OK
  /crypto/task/thread_error:                                           OK

which gives false positives if you are grepping build logs for
errors by looking for "error:". Since there are only three tests
with this problem, just rename them all to 'failure' instead.

5fc8c052ce throttle: Test burst limits lower than the normal limits
This checks that making FOO_max lower than FOO is not allowed.

We could also forbid having FOO_max == FOO, but that doesn't have
any odd side effects and it would require us to update several other
tests, so let's keep it simple.

7266ae91a1 qht: do not segfault when gathering stats from an uninitialized qht
So far, QHT functions assume that the passed qht has previously been
initialized--otherwise they segfault.

This patch makes an exception for qht_statistics_init, with the goal
of simplifying calling code. For instance, qht_statistics_init is
called from the 'info jit' dump, and given that under KVM the TB qht
is never initialized, we get a segfault. Thus, instead of complicating
the 'info jit' code with additional checks, let's allow passing an
uninitialized qht to qht_statistics_init.

While at it, add a test for this to test-qht.

Before the patch (for $ qemu -enable-kvm [...]):
(qemu) info jit
[...]

Program received signal SIGSEGV, Segmentation fault.

After the patch the "TB hash buckets", "TB hash occupancy"
and "TB hash avg chain" lines are omitted.

df2c35902e ppc patch queue 2016-07-29
Here are the current pending ppc and spapr related patches for
 qemu-2.7.  Given the freeze status, these are all bugfixes, with two
 exceptions:
 
   * There's some final rework of the vcpu hotplug model.  Specifically
     we add spapr specific code on the generic basis Igor established
     to make cpu_index stable for pseries-2.7 and later machine types.
       - This allows us to remove the limitation that cpu cores had to
         be inserted in linear order, and removed in LIFO order.
       - This is worth merging this late in 2.7 because it will avoid
         considerable future grief with management layers needing to
         discover whether out-of-order hotplug is possible, amongst
         other things.
       - For now we do add a constraint that the initial cpu cannot be
         unplugged.
   * We add two extra testcases to make check, for postcopy and
     drive_del on ppc64.
       - Not strictly bugfixes, but safe, because they don't affect the
         actual code, and increase test coverage.

As userfaultfd syscall is available on powerpc, migration
postcopy can be used.

This patch adds the support needed to test this on powerpc,
instead of using a bootsector to run code to modify memory,
we use a FORTH script in "boot-command" property.

As spapr machine doesn't support "-prom-env" argument
(the nvram is initialized by SLOF and not by QEMU),
"boot-command" is provided to SLOF via a file mapped nvram
(with "-drive file=...,if=pflash")

  commit 6661397446

  Date:   Wed Jul 20 14:23:10 2016 +0100

    scripts: refactor the VM class in iotests for reuse

was not properly tested and included a number of broken
bits.

 - The 'event_match' method was not moved into qemu.py
 - The 'self._args' list parameter in QEMUMachine needs
   to be copied otherwise modifications will affect the
   global 'qemu_opts' variable in iotests.py
 - The QEMUQtestMachine class methods had inverted
   parameter order for the super() calls
 - The QEMUQtestMachine class forgot to add
   '-machine accel=qtest'
 - The QEMUQtestMachine class constructor needs to set
   a default 'name' value before using it as it may
   be None
 - The QEMUQtestMachine class constructor needs to use
   named parameters when calling the super constructor
   as it is leaving out some positional parameters.
 - The 'qemu_prog' variable should be a string not a
   list in iotests.py
 - The VM classs constructor needs to use named
   parameters when calling the super constructor
   as it is leaving out some positional parameters.
 - The path to the socket-scm-helper needs to be
   passed into the QEMUMachine class

409437e16d tests: introduce a framework for testing migration performance
This introduces a moderately general purpose framework for
testing performance of migration.

The initial guest workload is provided by the included 'stress'
program, which is configured to spawn one thread per guest CPU
and run a maximally memory intensive workload. It will loop
over GB of memory, xor'ing each byte with data from a 4k array
of random bytes. This ensures heavy read and write load across
all of guest memory to stress the migration performance. While
running the 'stress' program will record how long it takes to
xor each GB of memory and print this data for later reporting.

The test engine will spawn a pair of QEMU processes, either on
the same host, or with the target on a remote host via ssh,
using the host kernel and a custom initrd built with 'stress'
as the /init binary. Kernel command line args are set to ensure
a fast kernel boot time (< 1 second) between launching QEMU and
the stress program starting execution.

None the less, the test engine will initially wait N seconds for
the guest workload to stablize, before starting the migration
operation. When migration is running, the engine will use pause,
post-copy, autoconverge, xbzrle compression and multithread
compression features, as well as downtime & bandwidth tuning
to encourage completion. If migration completes, the test engine
will wait N seconds again for the guest workooad to stablize on
the target host. If migration does not complete after a preset
number of iterations, it will be aborted.

While the QEMU process is running on the source host, the test
engine will sample the host CPU usage of QEMU as a whole, and
each vCPU thread. While migration is running, it will record
all the stats reported by 'query-migration'. Finally, it will
capture the output of the stress program running in the guest.

All the data produced from a single test execution is recorded
in a structured JSON file. A separate program is then able to
create interactive charts using the "plotly" python + javascript
libraries, showing the characteristics of the migration.

The data output provides visualization of the effect on guest
vCPU workloads from the migration process, the corresponding
vCPU utilization on the host, and the overall CPU hit from
QEMU on the host. This is correlated from statistics from the
migration process, such as downtime, vCPU throttling and iteration
number.

While the tests can be run individually with arbitrary parameters,
there is also a facility for producing batch reports for a number
of pre-defined scenarios / comparisons, in order to be able to
get standardized results across different hardware configurations
(eg TCP vs RDMA, or comparing different VCPU counts / memory
sizes, etc).

To use this, first you must build the initrd image

 $ make tests/migration/initrd-stress.img

To run a a one-shot test with all default parameters

 $ ./tests/migration/guestperf.py > result.json

This has many command line args for varying its behaviour.
For example, to increase the RAM size and CPU count and
bind it to specific host NUMA nodes

 $ ./tests/migration/guestperf.py \
       --mem 4 --cpus 2 \
       --src-mem-bind 0 --src-cpu-bind 0,1 \
       --dst-mem-bind 1 --dst-cpu-bind 2,3 \
       > result.json

Using mem + cpu binding is strongly recommended on NUMA
machines, otherwise the guest performance results will
vary wildly between runs of the test due to lucky/unlucky
NUMA placement, making sensible data analysis impossible.

To make it run across separate hosts:

 $ ./tests/migration/guestperf.py \
       --dst-host somehostname > result.json

To request that post-copy is enabled, with switchover
after 5 iterations

 $ ./tests/migration/guestperf.py \
       --post-copy --post-copy-iters 5 > result.json

Once a result.json file is created, a graph of the data
can be generated, showing guest workload performance per
thread and the migration iteration points:

 $ ./tests/migration/guestperf-plot.py --output result.html \
        --migration-iters --split-guest-cpu result.json

To further include host vCPU utilization and overall QEMU
utilization

 $ ./tests/migration/guestperf-plot.py --output result.html \
        --migration-iters --split-guest-cpu \
	--qemu-cpu --vcpu-cpu result.json

NB, the 'guestperf-plot.py' command requires that you have
the plotly python library installed. eg you must do

 $ pip install --user  plotly

Viewing the result.html file requires that you have the
plotly.min.js file in the same directory as the HTML
output. This js file is installed as part of the plotly
python library, so can be found in

  $HOME/.local/lib/python2.7/site-packages/plotly/offline/plotly.min.js

The guestperf-plot.py program can accept multiple json files
to plot, enabling results from different configurations to
be compared.

Finally, to run the entire standardized set of comparisons

  $ ./tests/migration/guestperf-batch.py \
       --dst-host somehost \
       --mem 4 --cpus 2 \
       --src-mem-bind 0 --src-cpu-bind 0,1 \
       --dst-mem-bind 1 --dst-cpu-bind 2,3
       --output tcp-somehost-4gb-2cpu

will store JSON files from all scenarios in the directory
named tcp-somehost-4gb-2cpu

95c975013a tests/docker/dockerfiles: new debian-bootstrap.docker
Together with the debian-bootstrap.pre script can now build an arbitrary
architecture of Debian using debootstrap. This allows debootstrap to set
up its first stage before the container is built.

To build a container you need a command line like:

  DEB_ARCH=armhf DEB_TYPE=testing \
    ./tests/docker/docker.py build \
    --include-executable=arm-linux-user/qemu-arm debian:armhf \
    ./tests/docker/dockerfiles/debian-bootstrap.docker

Although a number of non-debian systems package the debootstrap script
it is fairly portable in itself. Assuming we have some sort of fakeroot
implementation we can just clone the upstream repository and use the
script from there.

c818408e44 qapi: Implement boxed types for commands/events
Turn on the ability to pass command and event arguments in
a single boxed parameter, which must name a non-empty type
(although the type can be a struct with all optional members).
For structs, it makes it possible to pass a single qapi type
instead of a breakout of all struct members (useful if the
arguments are already in a struct or if the number of members
is large); for other complex types, it is now possible to use
a union or alternate as the data for a command or event.

The empty type may be technically feasible if needed down the
road, but it's easier to forbid it now and relax things to allow
it later, than it is to allow it now and have to special case
how the generated 'q_empty' type is handled (see commit 7ce106a9
for reasons why nothing is generated for the empty type).  An
alternate type is never considered empty, but now that a boxed
type can be either an object or an alternate, we have to provide
a trivial QAPISchemaAlternateType.is_empty().  The new call to
arg_type.is_empty() during QAPISchemaCommand.check() requires
that we first check the type in question; but there is no chance
of introducing a cycle since objects do not refer back to commands.

We still have a split in syntax checking between ad-hoc parsing
up front (merely validates that 'boxed' has a sane value) and
during .check() methods (if 'boxed' is set, then 'data' must name
a non-empty user-defined type).

Generated code is unchanged, as long as no client uses the
new feature.

48825ca419 qapi: Plumb in 'boxed' to qapi generator lower levels
The next patch will add support for passing a qapi union type
as the 'data' of a command.  But to do that, the user function
for implementing the command, as called by the generated
marshal command, must take the corresponding C struct as a
single boxed pointer, rather than a breakdown into one
parameter per member.  Even without a union, being able to use
a C struct rather than a list of parameters can make it much
easier to handle coding with QAPI.

This patch adds the internal plumbing of a 'boxed' flag
associated with each command and event.  In several cases,
this means adding indentation, with one new dead branch and
the remaining branch being the original code more deeply
nested; this was done so that the new implementation in the
next patch is easier to review without also being mixed with
indentation changes.

For this patch, no behavior or generated output changes, other
than the testsuite outputting the value of the new flag
(always False for now).

d0b182392d qapi: Require all branches of flat union enum to be covered
We were previously enforcing that all flat union branches were
found in the corresponding enum, but not that all enum values
were covered by branches.  The resulting generated code would
abort() if the user passes the uncovered enum value.

We don't automatically treat non-present branches in a flat
union as empty types, for symmetry with simple unions (there,
the enum type is generated from the list of all branches, so
there is no way to omit a branch but still have it be part of
the union).

A later patch will add shorthand so that branches that are empty
in flat unions can be declared as 'branch':{} instead of
'branch':'Empty', to avoid the need for an otherwise useless
explicit empty type.  [Such shorthand for simple unions is a bit
harder to justify, since we would still have to generate a
wrapper type that parses 'data':{}, rather than truly being an
empty branch with no additional siblings to the 'type' member.]

3ff2f67a7c block: ignore flush requests when storage is clean
Some guests (win2008 server for example) do a lot of unnecessary
flushing when underlying media has not changed. This adds additional
overhead on host when calling fsync/fdatasync.

This change introduces a write generation scheme in BlockDriverState.
Current write generation is checked against last flushed generation to
avoid unnessesary flushes.

The problem with excessive flushing was found by a performance test
which does parallel directory tree creation (from 2 processes).
Results improved from 0.424 loops/sec to 0.432 loops/sec.
Each loop creates 10^3 directories with 10 files in each.

This affected some blkdebug testcases that were expecting error logs from
failure-injected flushes which are now skipped entirely
(tests 026 071 089).

This also affects the performance of block jobs and thus BLOCK_JOB_READY
events for driver-mirror and active block-commit commands now arrives
faster, before QMP send successfully returns to caller (tests 141 144).

0b8b8753e4 coroutine: move entry argument to qemu_coroutine_create
In practice the entry argument is always known at creation time, and
it is confusing that sometimes qemu_coroutine_enter is used with a
non-NULL argument to re-enter a coroutine (this happens in
block/sheepdog.c and tests/test-coroutine.c).  So pass the opaque value
at creation time, for consistency with e.g. aio_bh_new.

Mostly done with the following semantic patch:

@ entry1 @
expression entry, arg, co;
@@
- co = qemu_coroutine_create(entry);
+ co = qemu_coroutine_create(entry, arg);
  ...
- qemu_coroutine_enter(co, arg);
+ qemu_coroutine_enter(co);

@ entry2 @
expression entry, arg;
identifier co;
@@
- Coroutine *co = qemu_coroutine_create(entry);
+ Coroutine *co = qemu_coroutine_create(entry, arg);
  ...
- qemu_coroutine_enter(co, arg);
+ qemu_coroutine_enter(co);

@ entry3 @
expression entry, arg;

except for the aforementioned few places where the semantic patch

7f0317cfc8 blockjob: Add 'job_id' parameter to block_job_create()
When a new job is created, the job ID is taken from the device name of
the BDS. This patch adds a new 'job_id' parameter to let the caller
provide one instead.

This patch also verifies that the ID is always unique and well-formed.
This causes problems in a couple of places where no ID is being set,
because the BDS does not have a device name.

In the case of test_block_job_start() (from test-blockjob-txn.c) we
can simply use this new 'job_id' parameter to set the missing ID.

In the case of img_commit() (from qemu-img.c) we still don't have the
API to make commit_active_start() set the job ID, so we solve it by
setting a default value. We'll get rid of this as soon as we extend
the API.

a15fcc3cf6 qapi: Add new clone visitor
We have a couple places in the code base that want to deep-clone
one QAPI object into another, and they were resorting to serializing
the struct out to QObject then reparsing it.  A much more efficient
version can be done by adding a new clone visitor.

Since cloning is still relatively uncommon, expose the use of the
new visitor via a QAPI_CLONE() macro that takes care of type-punning
the underlying function pointer, rather than generating lots of
unused functions for types that won't be cloned.  And yes, we're
relying on the compiler treating all pointers equally, even though
a strict C program cannot portably do so - but we're not the first
one in the qemu code base to expect it to work (hello, glib!).

The choice of adding a fourth visitor type deserves some explanation.
On the surface, the clone visitor is mostly an input visitor (it
takes arbitrary input - in this case, another QAPI object - and
creates a new QAPI object during the course of the visit).  But
ever since commit da72ab0 consolidated enum visits based on the
visitor type, using VISITOR_INPUT would cause us to run
visit_type_str(), even though for cloning there is nothing to do
(we just copy the enum value across, without regards to its mapping
to strings).   Also, since our input happens to be a QAPI object,
we can also satisfy the internal checks for VISITOR_OUTPUT.  So in
the end, I settled with a new VISITOR_CLONE, and chose its value
such that many internal checks can use 'v->type & mask', sticking
to 'v->type == value' where the difference matters.

Note that we can only clone objects (including alternates) and lists,
not built-ins or enums.  The visitor core hides integer width from
the actual visitor (since commit 04e070d), and as long as that's the
case, we can't clone top-level integers.  Then again, those can
always be cloned by direct copy, since they are not objects with
deep pointers, so it's no real loss.  And restricting cloning to
just objects and lists is cleaner than restricting it to non-integers.
As such, I documented that the clone visitor is for direct use only
by code internal to QAPI, and should not be used on incomplete objects
(other than a hack to work around the fact that we allow NULL in place
of "" in visit_type_str() in other output visitors).  Note that as
written, the clone visitor will never fail on a complete object.

Scalars (including enums) not at the root of the clone copy just fine
with no additional effort while visiting the scalar, by virtue of a
g_memdup() each time we push another struct onto the stack.  Cloning
a string requires deduplication of a pointer, which means it can also
provide the guarantee of an input visitor of never producing NULL
even when still accepting NULL in place of "" the way the QMP output
visitor does.

Cloning an 'any' type could be possible by incrementing the QObject
refcnt, but it's not obvious whether that is better than implementing
a QObject deep clone.  So for now, we document it as unsupported,
and intentionally omit the .type_any() callback to let a developer
know their usage needs implementation.

Add testsuite coverage for several different clone situations, to
ensure that the code is working.  I also tested that valgrind was
happy with the test.

3b098d5697 qapi: Add new visit_complete() function
Making each output visitor provide its own output collection
function was the only remaining reason for exposing visitor
sub-types to the rest of the code base.  Add a polymorphic
visit_complete() function which is a no-op for input visitors,
and which populates an opaque pointer for output visitors.  For
maximum type-safety, also add a parameter to the output visitor
constructors with a type-correct version of the output pointer,
and assert that the two uses match.

This approach was considered superior to either passing the
output parameter only during construction (action at a distance
during visit_free() feels awkward) or only during visit_complete()
(defeating type safety makes it easier to use incorrectly).

Most callers were function-local, and therefore a mechanical
conversion; the testsuite was a bit trickier, but the previous
cleanup patch minimized the churn here.

The visit_complete() function may be called at most once; doing
so lets us use transfer semantics rather than duplication or
ref-count semantics to get the just-built output back to the
caller, even though it means our behavior is not idempotent.

Generated code is simplified as follows for events:

2c0ef9f411 qapi: Add new visit_free() function
Making each visitor provide its own (awkwardly-named) FOO_cleanup()
is unusual, when we can instead have a polymorphic visit_free()
interface.  Over the next few patches, we can use the polymorphic
functions to eliminate the need for a FOO_get_visitor() function
for accessing specific visitor functionality, once everything can
be accessed directly through the Visitor* interfaces.

The dealloc visitor is the first one converted to completely use
the new entry point, since qapi_dealloc_visitor_cleanup() was the
only reason that qapi_dealloc_get_visitor() existed, and only
generated and testsuite code was even using it.  With the new
visit_free() entry point in place, we no longer need to expose
the QapiDeallocVisitor subtype through qapi_dealloc_visitor_new(),
and can get by with less generated code, with diffs that look like:

| void qapi_free_ACPIOSTInfo(ACPIOSTInfo *obj)
| {
|-    QapiDeallocVisitor *qdv;
|     Visitor *v;
|
|     if (!obj) {
|         return;
|     }
|
|-    qdv = qapi_dealloc_visitor_new();
|-    v = qapi_dealloc_get_visitor(qdv);
|+    v = qapi_dealloc_visitor_new();
|     visit_type_ACPIOSTInfo(v, NULL, &obj, NULL);
|-    qapi_dealloc_visitor_cleanup(qdv);
|+    visit_free(v);
|}

1158bb2a05 qapi: Add parameter to visit_end_*
Rather than making the dealloc visitor track of stack of pointers
remembered during visit_start_* in order to free them during
visit_end_*, it's a lot easier to just make all callers pass the
same pointer to visit_end_*.  The generated code has access to the
same pointer, while all other users are doing virtual walks and
can pass NULL.  The dealloc visitor is then greatly simplified.

All three visit_end_*() functions intentionally take a void**,
even though the visit_start_*() functions differ between void**,
GenericList**, and GenericAlternate**.  This is done for several
reasons: when doing a virtual walk, passing NULL doesn't care
what the type is, but when doing a generated walk, we already
have to cast the caller's specific FOO* to call visit_start,
while using void** lets us use visit_end without a cast. Also,
an upcoming patch will add a clone visitor that wants to use
the same implementation for all three visit_end callbacks,
which is made easier if all three share the same signature.

For visitors with already track per-object state (the QMP visitors
via a stack, and the string visitors which do not allow nesting),
add an assertion that the caller is indeed passing the same
pointer to paired calls.

58e19e6e79 log: Clean up misuse of Range for -dfilter
Range encodes an integer interval [a,b] as { begin = a, end = b + 1 },
where a \in [0,2^64-1] and b \in [1,2^64].  Thus, zero end is to be
interpreted as 2^64.

The implementation of -dfilter (commit 3514552) uses Range
differently: it encodes [a,b] as { begin = a, end = b }.  The code
works, but it contradicts the specification of Range in range.h.

Switch to the specified representation.  Since it can't represent
[0,UINT64_MAX], we have to reject that now.  Add a test for it.

While we're rejecting anyway: observe that we reject -dfilter LOB..UPB
where LOB > UPB when UPB is zero, but happily create an empty Range
when it isn't.  Reject it then, too, and add a test for it.

While there, add a positive test for the problematic upper bound
UINT64_MAX.

0c16c056a4 crypto: switch hash code to use nettle/gcrypt directly
Currently the internal hash code is using the gnutls hash APIs.
GNUTLS in turn is wrapping either nettle or gcrypt. Not only
were the GNUTLS hash APIs not added until GNUTLS 2.9.10, but
they don't expose support for all the algorithms QEMU needs
to use with LUKS.

Address this by directly wrapping nettle/gcrypt in QEMU and
avoiding GNUTLS's extra layer of indirection. This gives us
support for hash functions on a much wider range of platforms
and opens up ability to support more hash functions. It also
avoids a GNUTLS bug which would not correctly handle hashing
of large data blocks if int != size_t.

If a QAPI struct has a mandatory alternate member which is not
present on input, the input visitor reports an error for the
missing alternate without setting the discriminator, but the
cleanup code for the struct still tries to use the dealloc
visitor to clean up the alternate.

Commit dbf11922 changed visit_start_alternate to set *obj to NULL
when an error occurs, where it was previously left untouched.
Thus, before the patch, the dealloc visitor is blindly trying to
cleanup whatever branch corresponds to (*obj)->type == 0 (that is,
QTYPE_NONE, because *obj still pointed to zeroed memory), which
selects the default branch of the switch and sets an error, but
this second error is ignored by the way the dealloc visitor is
used; but after the patch, the attempt to switch dereferences NULL.

When cleaning up after a partial object parse, we specifically
check for !*obj after visit_start_struct() (see gen_visit_object());
doing the same for alternates fixes the crash. Enhance the testsuite
to give coverage for both missing struct and missing alternate
members.

Also add an abort - we expect visit_start_alternate() to either set an
error or to set (*obj)->type to a valid QType that corresponds to
actual user input, and QTYPE_NONE should never be reachable from valid
input.  Had the abort() been in place earlier, we might have noticed
the dealloc visitor dereferencing bogus zeroed memory prior to when
commit dbf11922 forced our hand by setting *obj to NULL and causing a
fault.

Test case:

{'execute':'blockdev-add', 'arguments':{'options':{'driver':'raw'}}}

The choice of 'driver':'raw' selects a BlockdevOptionsGenericFormat
struct, which has a mandatory 'file':'BlockdevRef' in QAPI.  Since
'file' is missing as a sibling of 'driver', this should report a
graceful error rather than fault.  After this patch, we are back to:

{"error": {"class": "GenericError", "desc": "Parameter 'file' is missing"}}

Generated code in qapi-visit.c changes as:

daa76aa416 log: Fix qemu_set_log_filename() error handling
When qemu_set_log_filename() detects an invalid file name, it reports
an error, closes the log file (if any), and starts logging to stderr
(unless daemonized or nothing is being logged).

This is wrong.  Asking for an invalid log file on the command line
should be fatal.  Asking for one in the monitor should fail without
messing up an existing logfile.

Fix by converting qemu_set_log_filename() to Error.  Pass it
&error_fatal, except for hmp_logfile report errors.

This also permits testing without a subprocess, so do that.

fcbf4a3c0c ppc / sparc: Add a tester for checking whether OpenBIOS runs successfully
Since the mac99 and g3beige PowerPC machines recently broke without
being noticed, it would be good to have a tester for "make check"
that detects such issues immediately. A simple way to test the firmware
of these machines is to use the "-prom-env" parameter of QEMU. This
parameter can be used to put some Forth code into the 'boot-command'
firmware variable which then can signal success to the tester by
writing a magic value to a known memory location. And since some of the
Sparc machines are also using OpenBIOS, they are now tested with this
prom-env-tester, too.

4616e3592b test: start vhost-user reconnect test
This is a simple reconnect test, that simply checks if vhost-user
reconnection is possible and restore the state. A more complete test
would actually manipulate and check the ring contents (such extended
testing would benefit from the libvhost-user proposed in QEMU list to
avoid duplication of ring manipulations)

523b018dde tests/vhost-user-bridge: workaround stale vring base
This patch is a similar solution to what Yuanhan Liu/Huawei Xie have
suggested for DPDK. When vubr quits (killed or crashed), a restart of
vubr would get stale vring base from QEMU. That would break the kernel
virtio net completely, making it non-work any more, unless a driver
reset is done.

So, instead of getting the stale vring base from QEMU, Huawei suggested
we could get a proper one from used->idx. This works because the queues
packets are processed in order.

8c0dcbc4ad block: drop support for using qcow[2] encryption with system emulators
Back in the 2.3.0 release we declared qcow[2] encryption as
deprecated, warning people that it would be removed in a future
release.

  commit a1f688f415
  Author: Markus Armbruster <armbru@redhat.com>
  Date:   Fri Mar 13 21:09:40 2015 +0100

    block: Deprecate QCOW/QCOW2 encryption

The code still exists today, but by a (happy?) accident we entirely
broke the ability to use qcow[2] encryption in the system emulators
in the 2.4.0 release due to

  commit 8336aafae1
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Tue May 12 17:09:18 2015 +0100

    qcow2/qcow: protect against uninitialized encryption key

This commit was designed to prevent future coding bugs which
might cause QEMU to read/write data on an encrypted block
device in plain text mode before a decryption key is set.

It turns out this preventative measure was a little too good,
because we already had a long standing bug where QEMU read
encrypted data in plain text mode during system emulator
startup, in order to guess disk geometry:

So the safety net is correctly preventing QEMU reading cipher
text as if it were plain text, during startup and aborting QEMU
to avoid bad usage of this data.

For added fun this bug only happens if the encrypted qcow2
file happens to have data written to the first cluster,
otherwise the cluster won't be allocated and so qcow2 would
not try the decryption routines at all, just return all 0's.

That no one even noticed, let alone reported, this bug that
has shipped in 2.4.0, 2.5.0 and 2.6.0 shows that the number
of actual users of encrypted qcow2 is approximately zero.

So rather than fix the crash, and backport it to stable
releases, just go ahead with what we have warned users about
and disable any use of qcow2 encryption in the system
emulators. qemu-img/qemu-io/qemu-nbd are still able to access
qcow2 encrypted images for the sake of data conversion.

In the future, qcow2 will gain support for the alternative
luks format, but when this happens it'll be using the
'-object secret' infrastructure for getting keys, which
avoids this problematic scenario entirely.

e7ed11f083 crypto: remove temp files on completion of secrets test
The secret object tests left some temporary files on disk
when completing. Ensure they are unlink, and rename them
to make it more obvious where they come from.

515864a0d7 qht: add qht-bench, a performance benchmark
This serves as a performance benchmark as well as a stress test
for QHT. We can tweak quite a number of things, including the
number of resize threads and how frequently resizes are triggered.

A performance comparison of QHT vs CLHT[1] and ck_hs[2] using
this same benchmark program can be found here:
  http://imgur.com/a/0Bms4

The tests are run on a 64-core AMD Opteron 6376, pinning threads
to cores favoring same-socket cores. For each run, qht-bench is
invoked with:
  $ tests/qht-bench -d $duration -n $n -u $u -g $range
, where $duration is in seconds, $n is the number of threads,
$u is the update rate (0.0 to 100.0), and $range is the number
of keys.

Note that ck_hs's performance drops significantly as writes go
up, since it requires an external lock (I used a ck_spinlock)
around every write.

Also, note that CLHT instead of using a seqlock, relies on an
allocator that does not ever return the same address during the
same read-critical section. This gives it a slight performance
advantage over QHT on read-heavy workloads, since the seqlock
writes aren't there.

A few of those plots are shown in text here, since that site
might not be online forever. Throughput is on Mops/s on the Y axis.

ebb718a5c7 qcow2: Catch more unaligned write_zero into zero cluster
is_zero_cluster() and is_zero_cluster_top_locked() are used only
by qcow2_co_write_zeroes().  The former is too broad (we don't
care if the sectors we are about to overwrite are non-zero, only
that all other sectors in the cluster are zero), so it needs to
be called up to twice but with smaller limits - rename it along
with adding the neeeded parameter.  The latter can be inlined for
more compact code.

The testsuite change shows that we now have a sparser top file
when an unaligned write_zeroes overwrites the only portion of
the backing file with data.

Based on a patch proposal by Denis V. Lunev.

443668ca40 block: split write_zeroes always
We should split requests even if they are less than write_zeroes_alignment.
For example we can have the following request:
  offset 62k
  size   4k
  write_zeroes_alignment 64k
The original code sent 1 request covering 2 qcow2 clusters, and resulted
in both clusters being allocated. But by splitting the request, we can
cater to the case where one of the two clusters can be zeroed as a
whole, for only 1 cluster allocated after the operation.

d5aebef884 docker: Don't use eval trick on Makefile
The eval trick for defining DOCKER_SRC_COPY doesn't do anything
useful, as DOCKER_SRC_COPY is immediately expanded just after it
is defined, and CUR_TIME is already defined using ":=". Simply
define it using ":=" so it is evaluated only once.

The eval trick was also triggering an weird error on Travis builds:
  qemu/tests/docker/Makefile.include:34: *** unterminated variable reference.  Stop.

The issue is not easily reproducible (maybe it's a bug in some
versions of Make), but it is avoided if removing the eval trick.

In a similar vein to commit ee2bdc33c9
("throttle: refuse bps_max/iops_max without bps/iops") it is likely that
the user made a configuration error if iops-size has been set but no
iops limit has been set.

Print an error message so the user can check their throttling
configuration.  They should either remove iops-size if they don't want
any throttling or specify one of iops-total, iops-read, or iops-write.

271b385e7e tests: avoid coroutine pool test crash
Skip the test_co_queue test case if the coroutine pool is not enabled.
The test case does not work without the pool because it touches memory
belonging to a freed coroutine (on purpose).

605d52e62f net_pkt: Name vmxnet3 packet abstractions more generic
This patch drops "vmx" prefix from packet abstractions names
to emphasize the fact they are generic and not tied to any
specific network device.

These abstractions will be reused by e1000e emulation implementation
introduced by following patches so their names need generalization.

This patch (except renamed files, adjusted comments and changes in MAINTAINTERS)
was produced by:

324027c24c Makefile: Rules for docker testing
This adds a group of make targets to run docker tests, all are available
in source tree without running ./configure.

The usage is shown with "make docker".

Besides the fixed ones, dynamic targets for building each image and
running each test in each image are generated automatically by make,
scanning $(SRC_PATH)/tests/docker/ files with specific patterns.

Alternative to manually list particular targets (docker-TEST@IMAGE)
set, you can control which tests/images to run by filtering variables,
TESTS= and IMAGES=, which are expressed in Makefile pattern syntax,
"foo% %bar ...". For example:

    $ make docker-test IMAGES="ubuntu fedora"

Unfortunately, it's impossible to propagate "-j $JOBS" into make in
containers, however since each combination is made a first class target
in the top Makefile, "make -j$N docker-test" still parallels the tests
coarsely.

Still, $J is made a magic variable to let all make invocations in
containers to use -j$J.

Instead of providing a live version of the source tree to the docker
container we snapshot it with git-archive. This ensures the tree is in a
pristine state for whatever operations the container is going to run on
them.

Uncommitted changes known to files known by the git index will be
included in the snapshot if there are any.
