Now that moxiesim supports the -bios parameter, we can check this machine

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.

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.

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

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.

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.

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.

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.

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.

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

continue. This is because the 2nd is already waiting for the 1st, and
in wait_serialising_requests() there is:

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

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.

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.

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

Each entry in the qcow2 cache contains an offset field indicating the

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

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).

So run the luks test only if the required encryption support is available.

test_multi_co_schedule_entry() set to_schedule[id] in the final loop
iteration before terminating the coroutine. There is a race condition
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!
