The first test case would cause a huge memory allocation, leading to a
qemu abort; the second one to a too small malloc() for the catalog
(smaller than s->catalog_size), which causes a read-only out-of-bounds
array access and on big endian hosts an endianess conversion for an
undefined memory area.
The sample image used here is not an original Parallels image. It was
created using an hexeditor on the basis of the struct that qemu uses.
Good enough for trying to crash the driver, but not for ensuring
compatibility.

bs->total_sectors is not the highest possible sector number that could
be involved in a copy on write operation: VM state is after the end of
the virtual disk. This resulted in wrong values for the number of
sectors to be copied (n).
The code that checks for the end of the image isn't required any more
because the code hasn't been calling the block layer's bdrv_read() for a
long time; instead, it directly calls qcow2_readv(), which doesn't error
out on VM state sector numbers.

free_cluster_index is only correct if update_refcount() was called from
an allocation function, and even there it's brittle because it's used to
protect unfinished allocations which still have a refcount of 0 - if it
moves in the wrong place, the unfinished allocation can be corrupted.
So not using it any more seems to be a good idea. Instead, use the
first requested cluster to do the calculations. Return -EAGAIN if
unfinished allocations could become invalid and let the caller restart
its search for some free clusters.
The context of creating a snapsnot is one situation where
update_refcount() is called outside of a cluster allocation. For this
case, the change fixes a buffer overflow if a cluster is referenced in
an L2 table that cannot be represented by an existing refcount block.

Opening an encrypted image takes an additional step: setting the key.
Between open and the key set, the image must not be used.
We have some protection against accidental use in place: you can't
unpause a guest while we're missing keys. You can, however, hot-plug
block devices lacking keys into a running guest just fine, or insert
media lacking keys. In the latter case, notifying the guest of the
insert is delayed until the key is set, which may suffice to protect
at least some guests in common usage.
This patch makes the protection apply in more cases, in a rather
heavy-handed way: it doesn't let you open encrypted images unless
we're in a paused state.
It doesn't extend the protection to users other than the guest (block
jobs?). Use of runstate_check() from block.c is disgusting. Best I
can do right now.

If an assertion fails during qtest_init() the SIGABRT handler is
invoked. This is the correct behavior since we need to kill the QEMU
process to avoid leaking it when the test dies.
The global_qtest pointer used by the SIGABRT handler is currently only
assigned after qtest_init() returns. This results in a segfault if an
assertion failure occurs during qtest_init().
Move global_qtest assignment inside qtest_init(). Not pretty but let's

It can be useful to run an AioContext from a thread which normally does
not "own" the AioContext. For example, request draining can be
implemented by acquiring the AioContext and looping aio_poll() until all
requests have been completed.
The following pattern should work:
/* Event loop thread */
while (running) {
aio_context_acquire(ctx);
aio_poll(ctx, true);
aio_context_release(ctx);
}
/* Another thread */
aio_context_acquire(ctx);
bdrv_read(bs, 0x1000, buf, 1);
aio_context_release(ctx);
This patch implements aio_context_acquire() and aio_context_release().
Note that existing aio_poll() callers do not need to worry about
acquiring and releasing - it is only needed when multiple threads will
call aio_poll() on the same AioContext.

QemuMutex does not guarantee fairness and cannot be acquired
recursively:
Fairness means each locker gets a turn and the scheduler cannot cause
starvation.
Recursive locking is useful for composition, it allows a sequence of
locking operations to be invoked atomically by acquiring the lock around
them.
This patch adds RFifoLock, a recursive lock that guarantees FIFO order.
Its first user is added in the next patch.
RFifoLock has one additional feature: it can be initialized with an
optional contention callback. The callback is invoked whenever a thread

Older versions of gcc (eg 4.6) can't handle varargs functions declared
inline for anything other than completely trivial uses, and complain:
tests/qom-test.c: In function 'qmp': tests/libqtest.h:359:60: sorry,
unimplemented: function 'qmp' can never be inlined because it uses
variable argument lists
Avoid this problem by putting the functions into libqtest.c instead
of using inline definitions in libqtest.h.

'socket_accept' waits for QEMU to init its unix socket.
If QEMU encounters an error during command line parsing,
it can exit before initializing the communication channel.
Using a timeout for sockets fixes the issue.

Test the error class instead. Expecting a specific message is

Use g_assert_cmpstr() instead of combining g_assert() and strcmp(3).
This simplifies the code since we no longer have to play games to

By default, any union will automatically generate a enum type as
"[UnionName]Kind" in C code, and it is duplicated when the discriminator
is specified as a pre-defined enum type in schema. After this patch,
the pre-defined enum type will be really used as the switch case
condition in generated C code, if discriminator is an enum field.

For common union the patch will check whether base is a valid complex

whether discriminator is found in base, whether the key of every branch
is correct when discriminator is an enum type.

The QEMU process stays running if the test case fails. This patch fixes
the leak by installing a SIGABRT signal handler which invokes
qtest_end().

qtest_init() cannot use exec*p() to launch QEMU since the exec*p()
functions take an argument array while qtest_init() takes char
*extra_args. Therefore we execute /bin/sh -c <command-line> and let the
shell parse the argument string.
This left /bin/sh as our child process and our child's child was QEMU.
We still want QEMU's pid so the -pidfile option was used to let QEMU
report its pid.
The pidfile needs to be unlinked when the test case exits or fails. In
other words, the pidfile creates a new problem for us!
Simplify all this using the shell 'exec' command. It allows us to
replace the /bin/sh process with QEMU. Then we no longer need to use
-pidfile because we already know our fork child's pid.
Note: Yes, it seems silly to exec /bin/sh when we could just exec QEMU
directly. But remember qtest_init() takes a single char *extra_args
command-line fragment instead of a real argv[] array, so we need
/bin/sh's argument parsing behavior.

The 071 test is designed for IMGFMT=qcow2 because it uses the l2_load
blkdebug event. Its output filtering also assumes that IMGFMT is not
raw since 071.out contains "format=raw" but IMGFMT=raw would filter the
output to "format=IMGFMT".
Perhaps the test case can be rewritten to be more generic, but for now
let's document that it was only supposed to work with qcow2.

turn requires another file, i.e., nesting file formats.
Allowing nested file formats results in e.g. qcow2 BlockDriverStates
never being directly passed to bdrv_open_common() from bdrv_file_open(),
but instead being handed through bdrv_open(). This changes the error
message when trying to give a filename to qcow2, i.e. trying to use it

The current two GTest cases, /i440fx/defaults and /i440fx/pam can share a
qemu process, but the next two cases will need dedicated instances. It is
messy (and order-dependent) to dynamically configure GTest cases one by
one to start, stop, or keep the current qtest (*); let's just have each
GTest work with its own qtest. The performance difference should be
negligible.
(*) As g_test_run() can be invoked at most once per process startup, and
it runs GTest cases in sequence, we'd need clumsy data structures to
control each GTest case to start/stop/keep the qemu instance. Or, we'd
have to code the same information into the test methods themselves, which
would make them even more order-dependent.

SMTP does not preserve newlines. This is normally not a problem if the
email body uses DOS or UNIX newlines consistently. In 051.out we mix
UNIX newlines with DOS newlines (since QEMU monitor output uses \r\n).
This patch filters the QEMU monitor output so the golden master file
uses UNIX newlines exclusively.
The result is that patches touching 051.out will apply cleanly without
mangling newlines after this commit.

This patch drops a special case where aio_poll(ctx, true) returns false
instead of blocking if no file descriptors are waiting on I/O. Now it
is possible to block in aio_poll() to wait for aio_notify().
This change eliminates busy waiting. bdrv_drain_all() used to rely on
busy waiting to completed throttled I/O requests but this is no longer
required so we can simplify aio_poll().
Note that aio_poll() still returns false when aio_notify() was used. In
other words, stopping a blocking aio_poll() wait is not considered
making progress.
Adjust test-aio /aio/bh/callback-delete/one which assumed aio_poll(ctx,
true) would immediately return false instead of blocking.

This avoids each test needing to add it to suppress windows popping up.

43cd209803 ("qdev-monitor-test: add

-display none.
As a result, "make check" now tries to use graphics (GTK or SDL). Since
graphics are not used by the test and inappropriate for headless "make
check" runs, add the missing -display none.

This patch moves ret assignment after reporting original error.
We were lucky to pass qemu-iotests 048 (qemu-img compare case) but when
I tried to run with TEST_DIR=/tmp (tmpfs), it fails with a "wrong"
mismatch offset. This fixes two bugs.
In the first if branch, setting ret to 1 before using it makes dead code
in the next line: pnum is never added to mismatch offset even if ret was
0.
In the other if branch, currently the output error is always -4:
strerror(-4) -> Unknown error -4

Case 030 occasionally fails because of block job compltes too fast to be
captured by script, and 'unexpected qmp event' of job completion causes
the test failure.
Simply fill in some data to the test image to make this false alarm less

Add a test case for trying to open an image file where it is impossible

doing this, qemu (or qemu-io in this case) should not crash but rather

This adds a test case for Multiboot memory map in the tests/multiboot
directory, where future i386 test kernels can be dropped. Because this
requires an x86 build host and an installed 32 bit libgcc, the test is
not part of a regular 'make check'.
The reference output for the test is verified against test runs of the
same multiboot kernel booted by some GRUB 0.97.

This adds the VHDX format to the qemu-iotests format, and adds
a read test. The test reads from an existing sample image, that
was created with Hyper-V under Windwos Server 2012.
The image file is a 1GB dynamic image, with 32MB blocks.
The pattern 0xa5 exists from 0MB-33MB (past a block size boundary)
The pattern 0x96 exists from 33MB-66MB (past another block boundary,
and leaving a partial blank block)
From 66MB-1024MB, all reads should return 0.
Although 1GB dynamic image with 66MB of data, the bzip2'ed image
file size is only 874 bytes.
This also adds in the IMGFMT_GENERIC flag, so r/o images can be
tested (e.g. ./check -vhdx) without failing tests that assume
r/w support.

In _img_info, filter out additional information specific to the image
format provided by qemu-img info, since tests designed for multiple
image formats would produce different outputs for every image format
otherwise.
In a human-readable dump, that new information will always be last for
each "image information block" (multiple blocks are emitted when
inspecting the backing file chain). Every block is separated by an empty
line. Therefore, in this case, everything starting with the line "Format
specific information:" up to that empty line (or EOF, if it is the last
block) has to be stripped.
The JSON dump will always emit pretty JSON data. Therefore, the opening
and closing braces of every object will be on lines which are indented
by exactly the same amount, and all lines in between will have more
indentation. Thus, in this case, everything starting with a line
matching the regular expression /^ *"format-specific": {/ until /^ *},?/
has to be stripped, where the number of spaces at the beginning of the
respective lines is equal.

For image formats that are not "QEMU native", but supported for
compatibility, it is useful to verify that an image created with
the 'gold standard' native tool can be read / written to successfully
by QEMU.
In addition to testing non-native images, this could also be useful to
test against image files created by older versions of QEMU.
This provides a directory to store small sample images, for use by
scripts in tests/qemu-iotests.
Image files should be compressed with bzip2.
To use a sample image from a bash script, the _use_sample_img function
will copy and decompress the image into $TEST_DIR, and set $TEST_IMG to
be the decompressed sample image copy. To cleanup, call
_cleanup_test_img as normal.

When opening/creating images, propagating errors instead of immediately
emitting them on occurrence results in errors generally being printed on
a single line rather than being split up into multiple ones. This in
turn requires adjustments to some test results.
Also, test 060 used a sed to filter out the test image directory and
format by removing everything from the affected line after a certain
keyword; this now also removes the error message itself, which can be
fixed by using _filter_testdir and _filter_imgfmt.
Finally, _make_test_img in common.rc did not filter out the test image
directory etc. from stderr. This has been fixed through a redirection of
stderr to stdout (which is already done in _check_test_img and
_img_info).

The reference output for test case 026 hasn't been updated in a long

The problem with this test case is that it produces different output
depending on whether -nocache is used or not. The solution of this patch
is to actually have two different reference outputs. If nnn.out.nocache
exists, it is used as the reference output for -nocache; otherwise,
nnn.out stays valid for both cases.

Now that aio_poll() users check their termination condition themselves,
it is no longer necessary to call .io_flush() handlers.
The behavior of aio_poll() changes as follows:
1. .io_flush() is no longer invoked and file descriptors are *always*
monitored. Previously returning 0 from .io_flush() would skip this file
descriptor.
Due to this change it is essential to check that requests are pending
before calling qemu_aio_wait(). Failure to do so means we block, for
example, waiting for an idle iSCSI socket to become readable when there
are no requests. Currently all qemu_aio_wait()/aio_poll() callers check
before calling.
2. aio_poll() now returns true if progress was made (BH or fd handlers
executed) and false otherwise. Previously it would return true whenever
'busy', which means that .io_flush() returned true. The 'busy' concept
no longer exists so just progress is returned.
Due to this change we need to update tests/test-aio.c which asserts
aio_poll() return values. Note that QEMU doesn't actually rely on these
return values so only tests/test-aio.c cares.
Note that ctx->notifier, the EventNotifier fd used for aio_notify(), is
now handled as a special case. This is a little ugly but maintains
aio_poll() semantics, i.e. aio_notify() does not count as 'progress' and
aio_poll() avoids blocking when the user has not set any fd handlers yet.
Patches after this remove .io_flush() handler code until we can finally
drop the io_flush arguments to aio_set_fd_handler() and friends.

Granularity is used to calculate the cluster size and allocate r/w
buffer. Check the value from image before using it, so we don't abort()
for unbounded memory allocation.

The new poke_file function sets bytes at an offset in a file given a
printf-style format string. It can be used to corrupt an image file for
test coverage of error paths.

We don't want to commit to the API yet before everything is worked out.
Like already for 1.5, disable it again for the 1.6 release. This commit
is meant to be reverted after the 1.6 release.
The disabling of the driver-specific options is achieved by applying the
old checks while parsing the command line.

Five tests files for DSP instructions had wrong expected values in the tests.
This change fixes this, and this has been cross-checked by running the same
test binaries on Malta 74K board.

The parser has a rather unorthodox structure:
Until EOF:
Read a section:
Generator function get_expr() yields one section after the
other, as a string. An unindented, non-empty line that
isn't a comment starts a new section.
Lexing:
Split section into a list of tokens (strings), with help
of generator function tokenize().
Parsing:
Parse the first expression from the list of tokens, with
parse(), throw away any remaining tokens.
In parse_schema(): record value of an enum, union or
struct key (if any) in the appropriate global table,
append expression to the list of expressions.
Return list of expressions.
Known issues:
(1) Indentation is significant, unlike in real JSON.
(2) Neither lexer nor parser have any idea of source positions. Error
reporting is hard, let's go shopping.
(3) The one error we bother to detect, we "report" via raise.
(4) The lexer silently ignores invalid characters.
(5) If everything in a section gets ignored, the parser crashes.
(6) The lexer treats a string containing a structural character exactly
like the structural character.
(7) Tokens trailing the first expression in a section are silently
ignored.
(8) The parser accepts any token in place of a colon.
(9) The parser treats comma as optional.
(10) parse() crashes on unexpected EOF.
(11) parse_schema() crashes when a section's expression isn't a JSON
object.
Replace this piece of original art by a thoroughly unoriginal design.
Takes care of (1), (2), (5), (6) and (7), and lays the groundwork for
addressing the others. Generated source files remain unchanged.
