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.

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.

If we silence docker when --quiet is given, we should also silence the

* A number of preliminary patches for the powernv machine type
* A substantial cleanup of exception handling which will be

* 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

* Add some extra test cases for several machines (this isn't

NOTE: This pull request supersedes ppc-for-2.8-20160906, which had

qemu-system-ppc64 on BE hosts
* A small fix to Thomas' serial output test to avoid a warning on

* Some trivial checkpatch fixes

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.

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.

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.

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.

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.

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.

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.

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

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 [...]):

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")

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

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.

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.

[Test files renamed to *-boxed-*]
Signed-off-by: Markus Armbruster <armbru@redhat.com>
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).

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.]

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).

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.

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.

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.

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);

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.

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.

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.

not essiv, then we explicitly ignore any iv hash algorithm,
rather than report an error, for compatibility with dm-crypt.
When creating a new LUKS volume, if the iv generator is essiv

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"}}

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.

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.

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)

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.

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.

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.

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.

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.

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.
