d6ac6e9363 iotests: Split 177 into two parts for compat=0.10
When originally written, test 177 explicitly took care to run
with compat=0.10.  Then I botched my own test in commit
81c219ac and f0a9c18f, by adding additional actions that require
v3 images.  Split out the new code into a new v3-only test, 204,
and revert 177 back to its original state other than a new comment.

b01a1944e5 iotests: Filter compat-dependent info in 198
There is a bit of image-specific information which depends on the qcow2
compat level.  Filter it so that 198 works with compat=0.10 (and any
refcount_bits value).

Note that we cannot simply drop the --format-specific switch because we
do need the "encrypt" information.

7e0db6f442 iotests: Fix 051 for compat=0.10
051 has both compat=1.1 and compat=0.10 tests (once it uses
lazy_refcounts, once it tests that setting them does not work).
For the compat=0.10 tests, it already explicitly creates a suitable
image.  So let's just ignore the user-specified compat level for the
lazy_refcounts test and explicitly create a compat=1.1 image there, too.

This test does funny things like TEST_IMG="TEST_IMG.base" _make_test_img
that usually only work with the file protocol.  More specifically, they
do not work with the most interesting non-file protocols, so we might as
well skip this for anything but file.

1cc6169bb2 iotests: Drop format-specific in _filter_img_info
_filter_img_info should remove format-specific information, too.  We
already have such a filter in _img_info, and it is very useful for
query-block-named-block-nodes (etc.), too.

However, in 198 we need that information (but we still want the rest of
the filter), so make that filtering optional.  Note that "the rest of
the filter" includes filtering of the test directory, so we can drop the
_filter_testdir from 198 at the same time.

6bfc907dee qemu-iotests: Fix locking issue in 102
102 truncates a qcow2 file (the raw file) on purpose while a VM is
running.  However, image locking will usually prevent exactly this.

The fact that most people have not noticed until now (I suppose you may
have seen sporadic failures, but not taken them too seriously, like me)
further shows that this truncation is actually not really done
concurrently, but that the VM is still starting up by this point and has
not yet opened the image.  Remedy this by waiting for the monitor shell
to appear before the qemu-img invocation so we know the VM is up.

Likewise test_acpi_tables() name is to broad, while the function
only loads tables referenced by RSDT, rename it to reflect it.

b24b9d9472 tests: acpi: move tested tables array allocation outside of test_acpi_dsdt_table()
at best it's confusing that array for list of tables to be tested
against reference tables is allocated within test_acpi_dsdt_table()
and at worst it would just overwrite list of tables if they were
added before test_acpi_dsdt_table().
Move array initialization to test_acpi_one() before we start
processing tables.

d82c4f82e0 ACPI/unit-test: Add a testcase for RAM allocation in numa node
As QEMU supports the memory-less node, it is possible that there is
no RAM in the first numa node(also be called as node0). eg:
  ... \
  -m 128,slots=3,maxmem=1G \
  -numa node -numa node,mem=128M \

But, this makes it hard for QEMU to build a known-to-work ACPI SRAT
table. Only fixing it is not enough.

Add a testcase for this situation to make sure the ACPI table is
correct for guest.

2562755ee7 maint: Fix macros with broken 'do/while(0); ' usage
The point of writing a macro embedded in a 'do { ... } while (0)'
loop (particularly if the macro has multiple statements or would
otherwise end with an 'if' statement) is so that the macro can be
used as a drop-in statement with the caller supplying the
trailing ';'.  Although our coding style frowns on brace-less 'if':
  if (cond)
    statement;
  else
    something else;
that is the classic case where failure to use do/while(0) wrapping
would cause the 'else' to pair with any embedded 'if' in the macro
rather than the intended outer 'if'.  But conversely, if the macro
includes an embedded ';', then the same brace-less coding style
would now have two statements, making the 'else' a syntax error
rather than pairing with the outer 'if'.  Thus, even though our
coding style with required braces is not impacted, ending a macro
with ';' makes our code harder to port to projects that use
brace-less styles.

The change should have no semantic impact.  I was not able to
fully compile-test all of the changes (as some of them are
examples of the ugly bit-rotting debug print statements that are
completely elided by default, and I didn't want to recompile
with the necessary -D witnesses - cleaning those up is left as a
bite-sized task for another day); I did, however, audit that for
all files touched, all callers of the changed macros DID supply
a trailing ';' at the callsite, and did not appear to be used
as part of a brace-less conditional.

Found mechanically via: $ git grep -B1 'while (0);' | grep -A1 \\\\

241187c118 tests: Avoid 'do/while(false); ' in vhost-user-bridge
Use of a do/while(0) loop as a way to allow break statements in
the middle of execute-once code is unusual.  More typical is
the use of goto for early exits, with a label at the end of
the execute-once code, rather than nesting code in a scope;
however, the comment at the end of the existing code makes this
alternative a bit unpractical.

So, to avoid false positives from a future syntax check about
'while (false);', and to keep the loop form (in case someone
ever does add DONTWAIT support, where they can just as easily
manipulate the initial loop condition or add an if around the
final 'break'), I opted to use the form of a while(1) loop (the
break as an early exit is more idiomatic there), coupled with
a final break preserving the original comment.

e12c08d3b6 tests/boot-serial-test: Add code to allow to specify our own kernel or bios
QEMU only ships with some few firmware images, i.e. we can currently run
the boot-serial test only on a very limited set of machines. But writing
some characters to the default UART of a machine can often be done with
some few lines of assembly, so we add the possibility to the boot-serial
tester to use its own mini-kernels or mini-firmwares. We write such images
then into a file that we can load with the "-kernel" or "-bios" parameter
when we launch QEMU.

92b540dac9 tests/boot-serial-test: Make sure that we check the timeout regularly
If the guest continuesly writes characters to the UART, we never leave
the inner while loop and thus never check whether we've reached the
timeout value. So if we fail to find the expected string in the UART
output, the test just hangs and never finishs. Use a counter to regularly
break out of the while loop to check the timeout.

18b20bb43a tests/pxe-test: Add some extra tests
Previously virtio-net was only tested for ppc64 in "slow" mode.  That
doesn't make much sense since virtio-net is used much more often in
practice than the spapr-vlan device which was tested always.  So, move
virtio-net to always be tested on ppc64.

We had no tests at all for the q35 machine, which doesn't seem wise
given its increasing prominence.  Add a couple of tests for it,
including testing the newer e1000e adapter.

1e88989f6a tests/pxe-test: Use table of testcases rather than open-coding
Currently pxe-tests open codes the list of tests for each architecture.
This changes it to use tables of test parameters, somewhat similar to
boot-serial-test.

This adds the machine type into the table as well, giving us the ability
to perform tests on multiple machine types for architectures where there's
more than one machine type that matters.

NOTE: This changes the names of the tests in the output, to include the
      machine type and IPv4 vs. IPv6.  I'm not sure if this has the
      potential to break existing tooling.

5c96e091e8 tests/pxe-test: Remove unnecessary special case test functions
All of the x86 and some of the other test cases here use a common test
function, test_pxe_ipv4(), but one ppc and one s390 test use different
functions.

In the s390 case, this is completely pointless, the right parameter to
test_pxe_ipv4() will already do exactly the right thing.  For the
spapr-vlan case there's a slight difference - it will use IPv6 instead of
IPv4.

But testing just one case with IPv6 (and NOT IPv4) is rather haphazard.
Change everything to use the common test function, until we have a better
way of testing IPv6 across the board.

dbd73b569b Revert "docker: Enable features explicitly in test-full"
This reverts commit 5e8a7fe673.

It's hard to get all images to have all these packages, the usual
"FEATURES" and "require" mechanism doesn't scale with so many features.
With that change, the test basically only works in ubuntu.

Until a better way comes up, leave the feature enabling to ./configure
detection.

But don't remove the "-e" removal.

This patch let this info to be printed once test is running in

For the future it might be useful to fail the test if command has
failed, however it would require a bit of rework inside test
engine itself.

A simple example of silent failure without reporting it would to
add some non-existent HMP command into 'hmp_cmds' list. In this case
test will report it successfully passed without error.

2807746ff1 iotests: Fix 176 on 32-bit host
The contents of a qcow2 bitmap are rounded up to a size that
matches the number of bits available for the granularity, but
that granularity differs for 32-bit hosts (our default 64k
cluster allows for 2M bitmap coverage per 'long') and 64-bit
hosts (4M bitmap per 'long').  If the image is a multiple of
2M but not 4M, then the number of bytes occupied by the array
of longs in memory differs between architecture, thus
resulting in different SHA256 hashes.

Furthermore (but untested by me), if our computation of the
SHA256 hash is at all endian-dependent because of how we store
data in memory, that's another variable we'd have to account
for (ideally, we specified the bitmap stored in qcow2 as
fixed-endian on disk, because the same qcow2 file must be
usable across any architecture; but that says nothing about
how we represent things in memory).  But we already have test
165 to validate that bitmaps are stored correctly on disk,
while this test is merely testing that the bitmap exists.

So for this test, the easiest solution is to filter out the
actual hash value.  Broken in commit 4096974e.

50a3efb0f0 block: Close a BlockDriverState completely even when bs->drv is NULL
bdrv_close() skips much of its logic when bs->drv is NULL. This is
fine when we're closing a BlockDriverState that has just been created
(because e.g the initialization process failed), but it's not enough
in other cases.

For example, when a valid qcow2 image is found to be corrupted then
QEMU marks it as such in the file header and then sets bs->drv to
NULL in order to make the BlockDriverState unusable. When that BDS is
later closed then many of its data structures are not freed (leaking
their memory) and none of its children are detached. This results in
bdrv_close_all() failing to close all BDSs and making this assertion
fail when QEMU is being shut down:

   bdrv_close_all: Assertion `QTAILQ_EMPTY(&all_bdrv_states)' failed.

This patch makes bdrv_close() do the full uninitialization process
in all cases. This fixes the problem with corrupted images and still
works fine with freshly created BDSs.

4efb1f7c61 qcow2: Refuse to get unaligned offsets from cache
Instead of using an assertion, it is better to emit a corruption event
here.  Checking all offsets for correct alignment can be tedious and it
is easily possible to forget to do so.  qcow2_cache_do_get() is a
function every L2 and refblock access has to go through, so this is a
good central point to add such a check.

And for good measure, let us also add an assertion that the offset is
non-zero.  Making this a corruption event is not feasible, because a
zero offset usually means something special (such as the cluster is
unused), so all callers should be checking this anyway.  If they do not,
it is their fault, hence the assertion here.

d470ad42ac block: Guard against NULL bs->drv
We currently do not guard everywhere against a NULL bs->drv where we
should be doing so.  Most of the places fixed here just do not care
about that case at all.

Some care implicitly, e.g. through a prior function call to
bdrv_getlength() which would always fail for an ejected BDS.  Add an
assert there to make it more obvious.

Other places seem to care, but do so insufficiently: Freeing clusters in
a qcow2 image is an error-free operation, but it may leave the image in
an unusable state anyway.  Giving qcow2_free_clusters() an error code is
not really viable, it is much easier to note that bs->drv may be NULL
even after a successful driver call.  This concerns bdrv_co_flush(), and
the way the check is added to bdrv_co_pdiscard() (in every iteration
instead of only once).

Finally, some places employ at least an assert(bs->drv); somewhere, that
may be reasonable (such as in the reopen code), but in
bdrv_has_zero_init(), it is definitely not.  Returning 0 there in case
of an ejected BDS saves us much headache instead.

4096974e18 qcow2: fix image corruption on commit with persistent bitmap
If an image contains persistent bitmaps, we cannot use the
fast path of bdrv_make_empty() to clear the image during
qemu-img commit, because that will lose the clusters related
to the bitmaps.

Also leave a comment in qcow2_read_extensions to remind future
feature additions to think about fast-path removal, since we
just barely fixed the same bug for LUKS encryption.

It's a pain that qemu-img has not yet been taught to manipulate,
or even at a very minimum display, information about persistent
bitmaps; instead, we have to use QMP commands.  It's also a
pain that only qeury-block and x-debug-block-dirty-bitmap-sha256
will allow bitmap introspection; but the former requires the
node to be hooked to a block device, and the latter is experimental.

After committing the qcow2 image contents into the base image, qemu-img

When this is done for qcow2 images, it blows away the LUKS encryption
header, making the resulting image unusable. There are two codepaths
for emptying a qcow2 image, and the second (slower) codepath leaves
the LUKS header intact, so force use of that codepath.

d04c155503 iotests: 077: Filter out 'resume' lines
In the "Overlapping multiple requests" cases, the 3rd reqs (the break
point B) doesn't wait for the 2nd, and once resumed the I/O will just
continue.  This is because the 2nd is already waiting for the 1st, and
in wait_serialising_requests() there is:

    /* If the request is already (indirectly) waiting for us, or
     * will wait for us as soon as it wakes up, then just go on
     * (instead of producing a deadlock in the former case). */
    if (!req->waiting_for) {
        /* actually break */
        ...
    }

Consequently, the following "sleep 100; resume A" command races with the
completion of that request, and sometimes results in an unexpected
order of output:

> @@ -56,9 +56,9 @@
>  wrote XXX/XXX bytes at offset XXX
>  XXX bytes, X ops; XX:XX:XX.X (XXX YYY/sec and XXX ops/sec)
>  blkdebug: Resuming request 'B'

Filter out the "Resuming request" lines to make the output
deterministic.

147b44be49 iotests: Use new-style NBD connections
Old-style NBD is deprecated upstream (it is documented, but no
longer implemented in the reference implementation), and it is
severely limited (it cannot support structured replies, which
means it cannot support efficient handling of zeroes), when
compared to new-style NBD.  We are better off having our iotests
favor new-style everywhere (although some explicit tests,
particularly 83, still cover old-style for back-compat reasons);
this is as simple as supplying the empty string as the default
export name, as it does not change the URI needed to connect a
client to the server.  This also gives us more coverage of the
just-added structured reply code, when not overriding $QEMU_NBD
to intentionally point to an older server.

19026817f7 iotests: Make 136 less flaky
136 executes some AIO requests without a final aio_flush; then it
advances the virtual clock and thus expects the last access time of the
device to be less than the current time when queried (i.e. idle_time_ns
to be greater than 0).  However, without the aio_flush, some requests
may be settled after the clock_step invocation.  In that case,
idle_time_ns would be 0 and the test fails.

Fix this by adding an aio_flush if any AIO request other than some other
aio_flush has been executed.

ddc7093eec iotests: Make 083 less flaky
083 has (at least) two issues:

1. By launching the nbd-fault-injector in background, it may not be
   scheduled until the first grep on its output file is executed.
   However, until then, that file may not have been created yet -- so it
   either does not exist yet (thus making the grep emit an error), or it
   does exist but contains stale data (thus making the rest of the test
   case work connect to a wrong address).
   Fix this by explicitly overwriting the output file before executing
   nbd-fault-injector.

2. The nbd-fault-injector prints things other than "Listening on...".
   It also prints a "Closing connection" message from time to time.  We
   currently invoke sed on the whole file in the hope of it only
   containing the "Listening on..." line yet.  That hope is sometimes
   shattered by the brutal reality of race conditions, so make the sed
   script more robust.

bc11aee2ac iotests: Make 055 less flaky
First of all, test 055 does a valiant job of invoking pause_drive()
sometimes, but that is worth nothing without blkdebug.  So the first
thing to do is to sprinkle a couple of "blkdebug::" in there -- with the
exception of the transaction tests, because the blkdebug break points
make the transaction QMP command hang (which is bad).  In that case, we
can get away with throttling the block job that it effectively is
paused.

Then, 055 usually does not pause the drive before starting a block job
that should be cancelled.  This means that the backup job might be
completed already before block-job-cancel is invoked; thus making the
test either fail (currently) or moot if cancel_and_wait() ignored this
condition.  Fix this by pausing the drive before starting the job.

This patch fixes two race conditions in 030:

1. The first is in TestENOSPC.test_enospc().  After resuming the job,
   querying it to confirm it is no longer paused may fail because in the

2. The second is in TestSetSpeed.test_set_speed_invalid(): Here, a
   stream job is started on a drive without any break points, with a
   block-job-set-speed invoked subsequently.  However, without any break
   points, the job might have completed in the meantime (on tmpfs at
   least); or it might complete before cancel_and_wait() which expects
   the job to still exist.  This can be fixed like everywhere else by
   pausing the drive (installing break points) before starting the job
   and letting cancel_and_wait() resume it.

6bf45d59f9 qcow2: Prevent allocating refcount blocks at offset 0
Each entry in the qcow2 cache contains an offset field indicating the
location of the data in the qcow2 image. If the offset is 0 then it
means that the entry contains no data and is available to be used when
needed.

Because of that it is not possible to store in the cache the first
cluster of the qcow2 image (offset = 0). This is not a problem because
that cluster always contains the qcow2 header and we're not using this
cache for that.

However, if the qcow2 image is corrupted it can happen that we try to
allocate a new refcount block at offset 0, triggering this assertion
and crashing QEMU:

  qcow2_cache_entry_mark_dirty: Assertion `c->entries[i].offset != 0' failed

This patch adds an explicit check for this scenario and a new test

0761562687 qemu-iotests: Test I/O limits with removable media
This test hotplugs a CD drive to a VM and checks that I/O limits can
be set only when the drive has media inserted and that they are kept
when the media is replaced.

This also tests the removal of a device with valid I/O limits set but
no media inserted. This involves deleting and disabling the limits
of a BlockBackend without BlockDriverState, a scenario that has been
crashing until the fixes from the last couple of patches.

1104d83c72 nbd-client: Refuse read-only client with BDRV_O_RDWR
The NBD spec says that clients should not try to write/trim to
an export advertised as read-only by the server.  But we failed
to check that, and would allow the block layer to use NBD with
BDRV_O_RDWR even when the server is read-only, which meant we
were depending on the server sending a proper EPERM failure for
various commands, and also exposes a leaky abstraction: using
qemu-io in read-write mode would succeed on 'w -z 0 0' because
of local short-circuiting logic, but 'w 0 0' would send a
request over the wire (where it then depends on the server, and
fails at least for qemu-nbd but might pass for other NBD
implementations).

With this patch, a client MUST request read-only mode to access
a server that is doing a read-only export, or else it will get
a message like:

can't open device nbd://localhost:10809/foo: request for write access conflicts with read-only export

It is no longer possible to even attempt writes over the wire
(including the corner case of 0-length writes), because the block
layer enforces the explicit read-only request; this matches the
behavior of qcow2 when backed by a read-only POSIX file.

Fix several iotests to comply with the new behavior (since
qemu-nbd of an internal snapshot, as well as nbd-server-add over QMP,
default to a read-only export, we must tell blockdev-add/qemu-io to
set up a read-only client).

test_multi_co_schedule_entry() set to_schedule[id] in the final loop

where the main thread attempts to enter the terminating or terminated
coroutine when signalling coroutines to stop:

  atomic_mb_set(&now_stopping, true);
  for (i = 0; i < NUM_CONTEXTS; i++) {
      ctx_run(i, finish_cb, NULL);  <--- enters dead coroutine!
      to_schedule[i] = NULL;
  }

Make sure only to set to_schedule[id] if this coroutine really needs to
be scheduled!

c1958e9d54 docker: Improved image checksum
When a base image locally defined by QEMU, such as in the debian images,
is updated, the dockerfile checksum mechanism in docker.py still skips
updating the derived image, because it only looks at the literal content
of the dockerfile, without considering changes to the base image.

For example we have a recent fix e58c1f9b35 that fixed
debian-win64-cross by updating its base image, debian8-mxe, but due to
above "feature" of docker.py the image in question is automatically NOT
rebuilt unless you add NOCACHE=1. It is noticed on Shippable:

https://app.shippable.com/github/qemu/qemu/runs/541/2/console

because after the fix is merged, the error still occurs, and the log
shows the container image is, as explained above, not updated.

This is because at the time docker.py was written, there wasn't any
dependencies between QEMU's docker images.

Now improve this to preprocess any "FROM qemu:*" directives in the
dockerfiles while doing checksum, and inline the base image's dockerfile
content, recursively. This ensures any changes on the depended _QEMU_
images are taken into account.

This means for external images that we expect to retrieve from docker
registries, we still do it as before. It is not perfect, because
registry images can get updated too. Technically we could substitute the
image name with its hex ID as obtained with $(docker images $IMAGE
--format="{{.Id}}"), but --format is not supported by RHEL 7, so leave
it for now.

guests, we can pass any values, and can use qemu-io to add
coverage that our rounding is correct regardless of the guest
alignment constraints.

Update iotest 177 to intentionally probe block status at
unaligned boundaries as well as with a bytes value that does not
map to 32-bit sectors, which also required tweaking the image
prep to leave an unallocated portion to the image under test.

0608e40e8e qemu-img: Drop redundant error message in compare
If a read error is encountered during 'qemu-img compare', we
were printing the "Error while reading offset ..." message twice;
this was because our helper function was awkward, printing output
on some but not all paths.  Fix it to consistently report errors
on all paths, so that the callers do not risk a redundant message,
and update the testsuite for the improved output.

Further simplify the code by hoisting the conversion from an error
message to an exit code into the helper function, rather than
repeating that logic at all callers (yes, the helper function is
now less generic, but it's a net win in lines of code).

4e2ca83e71 tcg: define CF_PARALLEL and use it for TB hashing along with CF_COUNT_MASK
This will enable us to decouple code translation from the value
of parallel_cpus at any given time. It will also help us minimize
TB flushes when generating code via EXCP_ATOMIC.

Note that the declaration of parallel_cpus is brought to exec-all.h
to be able to define there the "curr_cflags" inline.

78b27bade1 libqtest: Add qtest_[v]startf()
We have several callers that were formatting the argument strings
themselves; consolidate this effort by adding new convenience
functions directly in libqtest, and update some call-sites that
can benefit from it.

Note that the new functions qtest_startf() and qtest_vstartf()
behave more like qtest_init() (the caller must assign global_qtest
after the fact, rather than getting it implicitly set).  This helps
us prepare for future patches that get rid of the global variable,
by explicitly highlighting which tests still depend on it now.

b95b5a0a52 tests/prom-env: Bump the timeout, and test pseries only in slow mode
If QEMU has been compiled with the flags --enable-tcg-interpreter and
--enable-debug, the guest is running incredibly slow. The prom-env
test is approximately 10 times slower than normal in this case, and
it takes up to 500 seconds until the test with the pseries machine
finishs. While we should still look for ways to speed up the test
on the pseries machine here, let's bump the timeout to 600 seconds to
allow the test to pass with this unusal configuration already now.
Also move the pseries test into the "slow" category - since it is
really a very slow test.

ab06ec4357 tests/pxe: Test more NICs when running in SPEED=slow mode
The pxe-test is a very good test to excercise NICs, thus we should use
it to test all NICs that can be used by the BIOS for booting via network.
However, to avoid that the default testing time increases too much, the
additional NICs are only tested in the "make check SPEED=slow" mode.

The virtio-net NIC on ppc64 is now also only tested in slow mode, since
the test on ppc64 is really quite slow and we've got test coverage for
virtio-net in big endian mode now on s390x, too.

fb3b4e6d88 basevm: Call logging.basicConfig()
Just setting level=DEBUG when debug is enabled is not enough: we
need to set up a log handler if we want debug messages generated
using logging.getLogger(...).debug() to be printed.

This was not a problem before because logging.debug() calls
logging.basicConfig() implicitly, but it's safer to not rely on
that.

47500c6775 iotests: Fix 195 if IMGFMT is part of TEST_DIR
do_run_qemu() in iotest 195 first applies _filter_imgfmt when printing
qemu's command line and _filter_testdir only afterwards.  Therefore, if
the image format is part of the test directory path, _filter_testdir
will no longer apply and the actual output will differ from the
reference output even in case of success.

For example, TEST_DIR might be "/tmp/test-qcow2", in which case
_filter_imgfmt first transforms this to "/tmp/test-IMGFMT" which is no
longer recognized as the TEST_DIR by _filter_testdir.

Fix this by not applying _filter_imgfmt in do_run_qemu() but in
run_qemu() instead, and only after _filter_testdir.

461743390d iotests: Add test 197 for covering copy-on-read
Add a test for qcow2 copy-on-read behavior, including exposure
for the just-fixed bugs.

The copy-on-read behavior is always to a qcow2 image, but the
test is careful to allow running with most image protocol/format
combos as the backing file being copied from (luks being the
exception, as it is harder to pass the right secret to all the
right places).  In fact, for './check nbd', this appears to be
the first time we've had a qcow2 image wrapping NBD, requiring
an additional line in _filter_img_create to match the similar
line in _filter_img_info.

Invoking blkdebug to prove we don't write too much took some
effort to get working; and it requires that $TEST_WRAP (based
on $TEST_DIR) not be subject to word splitting.  We may decide
later to have the entire iotests suite use relative rather than
absolute names, to avoid problems inherited by the absolute
name of $PWD or $TEST_DIR, at which point the sanity check in
this commit could be simplified.

This test requires at least 2G of consecutive memory to succeed;
as such, it is prone to spurious failures, particularly on
32-bit machines under load.  This situation is detected and
triggers an early exit to skip the test, rather than a failure.
To manually provoke this setup on a beefier machine, I used:
  $ (ulimit -S -v 1000000; ./check -qcow2 197)

8803714b53 iotests: Restore stty settings on completion
Executing qemu with a terminal as stdin will temporarily alter stty
settings on that terminal (for example, disabling echo), because of
how we run both the monitor and any multiplexing with guest input.
Normally, qemu restores the original settings on exit; but if an
iotest triggers qemu to abort in the middle, we can be left with
the altered terminal setup.  This can make life very annoying when
debugging an iotest failure (not everyone remembers the trick of
blind-typing 'stty sane' without echo, and some people prefer
terminal settings that are slightly different than the defaults
picked by 'stty sane').

It is possible to avoid qemu corrupting the terminal by not passing
a terminal to qemu's stdin in the first place (as in, use
'./check ... </dev/null'), but that's extra typing to have to
remember.  But running 'exec </dev/null' in the harness seems like
it might be too heavy of a hammer.  So I instead went the the
solution of saving and restoring the stty settings, only when the
harness detects that it is run interactively.

I tested this patch by forcing an allocation failure (I can't
guarantee that this particular limit will work on all setups, but
it shows the idea):
 $ (ulimit -S -v 500000; ./check -qcow2 1)

bde70715b6 commit: Remove overlay_bs
We don't need to make any assumptions about the graph layout above the
top node of the commit operation any more. Remove the use of
bdrv_find_overlay() and related variables from the commit job code.

bdrv_drop_intermediate() doesn't use the 'active' parameter any more, so
we can just drop it.

The overlay node was previously added to the block job to get a
BLK_PERM_GRAPH_MOD. We really need to respect those permissions in
bdrv_drop_intermediate() now, but as long as we haven't figured out yet
how BLK_PERM_GRAPH_MOD is actually supposed to work, just leave a TODO
comment there.

With this change, it is now possible to perform another block job on an
overlay node without conflicts. qemu-iotests 030 is changed accordingly.
