Markus Armbruster 86cdf9ec8d json: Clean up headers
The JSON parser has three public headers, json-lexer.h, json-parser.h,
json-streamer.h.  They all contain stuff that is of no interest
outside qobject/json-*.c.

Collect the public interface in include/qapi/qmp/json-parser.h, and
everything else in qobject/json-parser-int.h.

Markus Armbruster dd98e84819 qjson: Have qobject_from_json() & friends reject empty and blank
The last case where qobject_from_json() & friends return null without
setting an error is empty or blank input.  Callers:

* block.c's parse_json_protocol() reports "Could not parse the JSON
  options".  It's marked as a work-around, because it also covered
  actual bugs, but they got fixed in the previous few commits.

* qobject_input_visitor_new_str() reports "JSON parse error".  Also
  marked as work-around.  The recent fixes have made this unreachable,
  because it currently gets called only for input starting with '{'.

* check-qjson.c's empty_input() and blank_input() demonstrate the
  behavior.

* The other callers are not affected since they only pass input with
  exactly one JSON value or, in the case of negative tests, one error.

Fail with "Expecting a JSON value" instead of returning null, and
simplify callers.

Markus Armbruster f9277915ee json: Fix streamer not to ignore trailing unterminated structures
json_message_process_token() accumulates tokens until it got the
sequence of tokens that comprise a single JSON value (it counts curly
braces and square brackets to decide).  It feeds those token sequences
to json_parser_parse().  If a non-empty sequence of tokens remains at
the end of the parse, it's silently ignored.  check-qjson.c cases
unterminated_array(), unterminated_array_comma(), unterminated_dict(),
unterminated_dict_comma() demonstrate this bug.

Fix as follows.  Introduce a JSON_END_OF_INPUT token.  When the
streamer receives it, it feeds the accumulated tokens to
json_parser_parse().

Markus Armbruster 2a4794ba14 qjson: Fix qobject_from_json() & friends for multiple values
qobject_from_json() & friends use the consume_json() callback to
receive either a value or an error from the parser.

When they are fed a string that contains more than either one JSON
value or one JSON syntax error, consume_json() gets called multiple
times.

When the last call receives a value, qobject_from_json() returns that
value.  Any other values are leaked.

When any call receives an error, qobject_from_json() sets the first
error received.  Any other errors are thrown away.

When values follow errors, qobject_from_json() returns both a value
and sets an error.  That's bad.  Impact:

* block.c's parse_json_protocol() ignores and leaks the value.  It's
  used to to parse pseudo-filenames starting with "json:".  The
  pseudo-filenames can come from the user or from image meta-data such
  as a QCOW2 image's backing file name.

* vl.c's parse_display_qapi() ignores and leaks the error.  It's used
  to parse the argument of command line option -display.

* vl.c's main() case QEMU_OPTION_blockdev ignores the error and leaves
  it in @err.  main() will then pass a pointer to a non-null Error *
  to net_init_clients(), which is forbidden.  It can lead to assertion
  failure or other misbehavior.

* check-qjson.c's multiple_values() demonstrates the badness.

* The other callers are not affected since they only pass strings with
  exactly one JSON value or, in the case of negative tests, one
  error.

The impact on the _nofail() functions is relatively harmless.  They
abort when any call receives an error.  Else they return the last
value, and leak the others, if any.

Fix consume_json() as follows.  On the first call, save value and
error as before.  On subsequent calls, if any, don't save them.  If
the first call saved a value, the next call, if any, replaces the
value by an "Expecting at most one JSON value" error.  Take care not
to leak values or errors that aren't saved.

Markus Armbruster f7617d45d4 json: Leave rejecting invalid interpolation to parser
Both lexer and parser reject invalid interpolation specifications.
The parser's check is useless.

The lexer ends the token right after the first bad character.  This
tends to lead to suboptimal error reporting.  For instance, input

    [ %04d ]

produces the tokens

    JSON_LSQUARE  [
    JSON_ERROR    %0
    JSON_INTEGER  4
    JSON_KEYWORD  d
    JSON_RSQUARE  ]

The parser then yields an error, an object and two more errors:

    error: Invalid JSON syntax
    object: 4
    error: JSON parse error, invalid keyword
    error: JSON parse error, expecting value

Dumb down the lexer to accept [A-Za-z0-9]*.  The parser's check is now
used.  Emit a proper error there.

The lexer now produces

    JSON_LSQUARE  [
    JSON_INTERP   %04d
    JSON_RSQUARE  ]

and the parser reports just

    JSON parse error, invalid interpolation '%04d'

Markus Armbruster 84a56f38b2 json: Pass lexical errors and limit violations to callback
The callback to consume JSON values takes QObject *json, Error *err.
If both are null, the callback is supposed to make up an error by
itself.  This sucks.

qjson.c's consume_json() neglects to do so, which makes
qobject_from_json() null instead of failing.  I consider that a bug.

The culprit is json_message_process_token(): it passes two null
pointers when it runs into a lexical error or a limit violation.  Fix
it to pass a proper Error object then.  Update the callbacks:

* monitor.c's handle_qmp_command(): the code to make up an error is
  now dead, drop it.

* qga/main.c's process_event(): lumps the "both null" case together
  with the "not a JSON object" case.  The former is now gone.  The
  error message "Invalid JSON syntax" is misleading for the latter.
  Improve it to "Input must be a JSON object".

* qobject/qjson.c's consume_json(): no update; check-qjson
  demonstrates qobject_from_json() now sets an error on lexical
  errors, but still doesn't on some other errors.

* tests/libqtest.c's qmp_response(): the Error object is now reliable,
  so use it to improve the error message.

Markus Armbruster 2cbd15aa6f json: Treat unwanted interpolation as lexical error
The JSON parser optionally supports interpolation.  The lexer
recognizes interpolation tokens unconditionally.  The parser rejects
them when interpolation is disabled, in parse_interpolation().
However, it neglects to set an error then, which can make
json_parser_parse() fail without setting an error.

Move the check for unwanted interpolation from the parser's
parse_interpolation() into the lexer's finite state machine.  When
interpolation is disabled, '%' is now handled like any other
unexpected character.

The next commit will improve how such lexical errors are handled.

Markus Armbruster 62815d85ae json: Redesign the callback to consume JSON values
The classical way to structure parser and lexer is to have the client
call the parser to get an abstract syntax tree, the parser call the
lexer to get the next token, and the lexer call some function to get
input characters.

Another way to structure them would be to have the client feed
characters to the lexer, the lexer feed tokens to the parser, and the
parser feed abstract syntax trees to some callback provided by the
client.  This way is more easily integrated into an event loop that
dispatches input characters as they arrive.

Our JSON parser is kind of between the two.  The lexer feeds tokens to
a "streamer" instead of a real parser.  The streamer accumulates
tokens until it got the sequence of tokens that comprise a single JSON
value (it counts curly braces and square brackets to decide).  It
feeds those token sequences to a callback provided by the client.  The
callback passes each token sequence to the parser, and gets back an
abstract syntax tree.

I figure it was done that way to make a straightforward recursive
descent parser possible.  "Get next token" becomes "pop the first
token off the token sequence".  Drawback: we need to store a complete
token sequence.  Each token eats 13 + input characters + malloc
overhead bytes.

Observations:

1. This is not the only way to use recursive descent.  If we replaced
   "get next token" by a coroutine yield, we could do without a
   streamer.

2. The lexer reports errors by passing a JSON_ERROR token to the
   streamer.  This communicates the offending input characters and
   their location, but no more.

3. The streamer reports errors by passing a null token sequence to the
   callback.  The (already poor) lexical error information is thrown
   away.

4. Having the callback receive a token sequence duplicates the code to
   convert token sequence to abstract syntax tree in every callback.

5. Known bug: the streamer silently drops incomplete token sequences.

This commit rectifies 4. by lifting the call of the parser from the
callbacks into the streamer.  Later commits will address 3. and 5.

The lifting removes a bug from qjson.c's parse_json(): it passed a
pointer to a non-null Error * in certain cases, as demonstrated by
check-qjson.c.

json_parser_parse() is now unused.  It's a stupid wrapper around
json_parser_parse_err().  Drop it, and rename json_parser_parse_err()
to json_parser_parse().

Peter Maydell 6b699ae1be tests/vm: Increase timeout waiting for VM to boot to 5 minutes
The VM tests currently have a timeout of 2 minutes for trying
to connect to ssh. Since the guest VM has to boot from cold
to the point of accepting inbound ssh during this time, if the
host machine is heavily loaded it can spuriously time out.
Increase the timeout from 2 to 5 minutes.

Thomas Huth 410573aa2c tests/device-introspect: Test with all machines, not only with "none"
Certain device introspection crashes used to only happen if you were
using a certain machine, e.g. if the machine was using serial_hd() or
nd_table[], and a device was trying to use these in its instance_init
function, too.

To be able to catch these problems, let's extend the device-introspect
test to check the devices on all machine types, with and without the
"-nodefaults" parameter (since this makes a difference sometimes, too).
Since this is a rather slow operation, and most of the problems are
already handled by testing with the "none" machine only, the test with
all machines is only run in the "make check SPEED=slow" mode.

Introspection should not change the qom-tree / qtree, so we should check

Thomas Huth 1f4a0d81af tests: Skip old versioned machine types in quick testing mode
The tests that check something for all machine types currently spend
a lot of time checking old machine types (like "pc-i440fx-2.0" for
example). The chances that we find something new there in addition
to checking the latest version of a machine type are pretty low, so
we should not waste the time of the developers by testing this again
and again in the "quick" testing mode.
Thus let's add some code to determine whether we are testing a current
machine type or an old one, and only test the old types if we are
running in "SPEED=slow" mode.
This decreases the testing time quite a bit now, e.g. the qom-test
now finishes within 4 seconds for qemu-system-x86_64 instead of 30
seconds when testing all machines.

Thomas Huth 880b169a45 tests/migration-test: Silence the kvm_hv message by default
When running "make check" on a non-POWER host, the output is quite
distorted like this:

  [...]
  GTESTER check-qtest-nios2
  GTESTER check-qtest-or1k
  GTESTER check-qtest-ppc64
Skipping test: kvm_hv not available Skipping test: kvm_hv not available Skipping test: kvm_hv not available Skipping test: kvm_hv not available   GTESTER check-qtest-ppcemb
  GTESTER check-qtest-ppc
  GTESTER check-qtest-riscv32
  GTESTER check-qtest-riscv64
  [...]

Move the check to the beginning of the main function instead, so that
we do not have to test the condition again and again for each test,
and better use g_test_message() instead of g_print() here, like it is
also done in ufd_version_check() already.

Paolo Bonzini 06d09a018f tests: virtio: separate ccw tests from libqos
Because qtest does not support s390 channel I/O, s390 only performs smoke tests on
those few devices that do not have any functional tests.  Therefore, every time we
add functional tests for a virtio device, the choice is between removing
those tests from the s390 suite (so that s390 actually _loses_ coverage)
or sprinkling the test with architecture checks.

This patch simply creates a ccw-specific test that only performs smoke tests on
all virtio-ccw devices.  If channel I/O support is ever added to qtest and libqos,
then this file can go away.  In the meanwhile, it simplifies maintenance and
makes sure that all virtio devices are tested.

Hervé Poussineau 54c86f5a48 hw/ppc: deprecate the machine type 'prep', replaced by '40p'
- prep machine is a fictional machine, so has no specifications. Which
  devices can be changed/added/removed without impact? Are interrupts
  correctly mapped?
- prep firmware (OHW) has support only for IDE drives (no SCSI).
  Booting from IDE has been broken approximatively 3 years ago, and nobody complained.
- OHW is limited on IDE boot to a specific set of OS loaders.
  These operating systems are of the 2004 time frame.
- OHW can use -kernel. Linux kernel freezes a long time after PS/2 mouse
  detection, and then screen becomes garbage. This was already broken in
  QEMU v2.7, 2 years ago, and nobody complained.

On the other side:
- 40p is a real machine, so emulation can be checked against
  hardware specifications
- OpenBIOS has support for SCSI block devices, including 40p LSI adapter
- OpenBIOS can start mostly all Linux kernels (including recent ones)
  and recent operating system (like NetBSD 7.1.2)

On a SPARC host that I'm using as a build test machine, the
boot-serial-test for the SPARC guest machines takes about 65
seconds to execute. This means that it hits the current
60 second timer on these tests. Push the timeout up so
that it doesn't trigger spuriously on slow hosts like this one.

Markus Armbruster f9e986d237 libqtest: Improve error reporting for bad read from QEMU
When read() from the qtest socket or the QMP socket fails or EOFs, we
report "Broken pipe" and exit(1).  This commonly happens when QEMU
crashes.  It also happens when QEMU refuses to run because the test
passed it bad arguments.  Sadly, we neglect to report either.

Improve this by calling abort() instead of exit(1), so kill_qemu()
runs, and reports how QEMU died.  This improves error reporting to
something like

    /x86_64/device/introspect/list: Broken pipe
    tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 6 (Aborted) (dumped core)

Three exit() remain in libqtest.c:

* In qmp_response(), when we can't parse a QMP reply read from the QMP
  socket.  Change to abort() for consistency.

* In qtest_qemu_binary(), when QTEST_QEMU_BINARY isn't in the
  environment.  This can only happen before we start QEMU.  Leave
  alone.

* In qtest_init_without_qmp_handshake(), when the fork()ed child fails
  to execlp().  Leave alone.

exit() elsewhere are unlikely due to QEMU dying on us.  If that should
turn out to be wrong, we can move kill_qemu() from @abrt_hooks to
atexit() or something.

Eric Blake 71a268a5fd tests/libqtest: Improve kill_qemu()
In kill_qemu() we have an assert that checks that the QEMU process
didn't dump core:
            assert(!WCOREDUMP(wstatus));

Unfortunately the WCOREDUMP macro here means the resulting message
is not very easy to comprehend on at least some systems:

ahci-test: tests/libqtest.c:113: kill_qemu: Assertion `!(((__extension__ (((union { __typeof(wstatus) __in; int __i; }) { .__in = (wstatus) }).__i))) & 0x80)' failed.

and it doesn't identify what signal the process took. What's more,
WCOREDUMP is not reliable - in some cases, setrlimit() coupled with
kernel dump settings can result in the flag not being set.  It's
better to log ALL death by signal, instead of caring whether a core
dump was attempted (although once we know a signal happened, also
mentioning if a core dump is present can be helpful).

Furthermore, we are NOT detecting EINTR (while EINTR shouldn't be
happening if we didn't install signal handlers, it's still better
to always be robust).

Finally, even non-signal death with a non-zero status is suspicious,
since qemu's SIGINT handler is supposed to result in exit(0).

Instead of using a raw assert, print the information in an
easier to understand way:

/i386/ahci/sanity: tests/libqtest.c:129: kill_qemu() detected QEMU death from signal 11 (Segmentation fault) (core dumped)

(Of course, the really useful information would be why the QEMU
process dumped core in the first place, but we don't have that
by the time the test program has picked up the exit status.)

QMP input manually, as explained in the recent commit "tests: Clean up
string interpolation into QMP input (simple cases)".

migration-test.c interpolates strings into JSON in a few places:

* migrate_set_parameter() interpolates string parameter @value as a
  JSON number.  Change it to long long.  This requires changing
  migrate_check_parameter() similarly.

* migrate_set_capability() interpolates string parameter @value as a
  JSON boolean.  Change it to bool.

* deprecated_set_speed() interpolates string parameter @value as a
  JSON number.  Change it to long long.

Markus Armbruster 82cab70bd8 tests: Clean up string interpolation around qtest_qmp_device_add()
Leaving interpolation into JSON to qmp() is more robust than building
QMP input manually, as explained in the commit before previous.

qtest_qmp_device_add() and its wrappers interpolate into JSON as
follows:

* qtest_qmp_device_add() interpolates members into a JSON object.

* So do its wrappers qpci_plug_device_test() and usb_test_hotplug().

* usb_test_hotplug() additionally interpolates strings and numbers
  into JSON strings.

Clean them up:

* Have qtest_qmp_device_add() take its extra device properties as
  arguments for qdict_from_jsonf_nofail() instead of a string
  containing JSON members.

* Drop qpci_plug_device_test(), use qtest_qmp_device_add()
  directly.

* Change usb_test_hotplug() parameter @port to string, to avoid
  interpolation.  Interpolate @hcd_id separately.

Haswell-x86_64-cpu with device_add.  It passes socket-id, core-id,

test_plug_with_device_add_coreid() plugs power8_v2.0-spapr-cpu-core
and qemu-s390x-cpu with device_add.  It passes core-id as JSON string.
The properties are actually integers.

Passing JSON string values to integer properties works only due to

numbers.  While there, use %u rather than %i with unsigned int.

Markus Armbruster 015715f554 tests: Clean up string interpolation into QMP input (simple cases)
When you build QMP input manually like this

    cmd = g_strdup_printf("{ 'execute': 'migrate',"
                          "'arguments': { 'uri': '%s' } }",
                          uri);
    rsp = qmp(cmd);
    g_free(cmd);

you're responsible for escaping the interpolated values for JSON.  Not
done here, and therefore works only for sufficiently nice @uri.  For
instance, if @uri contained a single "'", qobject_from_vjsonf_nofail()
would abort.  A sufficiently nasty @uri could even inject unwanted
members into the arguments object.

Leaving interpolation into JSON to qmp() is more robust:

    rsp = qmp("{ 'execute': 'migrate', 'arguments': { 'uri': %s } }", uri);

It's also more concise.

Clean up the simple cases where we interpolate exactly a JSON value.

Commit ab45015a96 "qobject: Let qobject_from_jsonf() fail instead of
abort" fails to accomplish its stated aim: the function can still
abort due to its use of &error_abort.

Its rationale for letting it fail is that all remaining users cope
fine with failure.  Well, they're just fine with aborting, too; it's
what they do on failure.

Simply reverting the broken commit would bring back the unfortunate
asymmetry between qobject_from_jsonf() and qobject_from_jsonv(): one
aborts, the other returns null.  So also rename it to
qobject_from_jsonf_nofail().

them, with a TODO comment asking for cleanup.

Kevin Wolf 86fae10c64 mirror: Fail gracefully for source == target
blockdev-mirror with the same node for source and target segfaults
today: A node is in its own backing chain, so mirror_start_job() decides
that this is an active commit. When adding the intermediate nodes with
block_job_add_bdrv(), it starts the iteration through the subchain with
the backing file of source, though, so it never reaches target and
instead runs into NULL at the base.

While we could fix that by starting with source itself, there is no
point in allowing mirroring a node into itself and I wouldn't be
surprised if this caused more problems later.

So just check for this scenario and error out.

This reinstates commit b008326744,
which was temporarily reverted for the 3.0 release so that libvirt gets
some extra time to update their command lines.

The -drive option serial was deprecated in QEMU 2.10. It's time to
remove it.

Tests need to be updated to set the serial number with -global instead
of using the -drive option.

This reinstates commit a7aff6dd10,
which was temporarily reverted for the 3.0 release so that libvirt gets
some extra time to update their command lines.

The -drive options cyls, heads, secs and trans were deprecated in
QEMU 2.10. It's time to remove them.

hd-geo-test tested both the old version with geometry options in -drive
and the new one with -device. Therefore the code using -drive doesn't
have to be replaced there, we just need to remove the -drive test cases.
This in turn allows some simplification of the code.

Alberto Garcia 3db3e9c621 qemu-iotests: Update 093 to improve the draining test
The previous patch fixes a problem in which draining a block device
with more than one throttled request can make it wait first for the
completion of requests in other members of the same group.

This patch updates test_remove_group_member() in iotest 093 to
reproduce that scenario. This updated test would hang QEMU without the
fix from the previous patch.

Alberto Garcia ef7a6a3c2a qemu-iotests: Test removing a throttle group member with a pending timer
A throttle group can have several members, and each one of them can
have several pending requests in the queue.

The requests are processed in a round-robin fashion, so the algorithm
decides the drive that is going to run the next request and sets a
timer in it. Once the timer fires and the throttled request is run
then the next drive from the group is selected and a new timer is set.

If the user tried to remove a drive from a group and that drive had a
timer set then the code was not taking care of setting up a new timer
in one of the remaining members of the group, freezing their I/O.

This problem was fixed in 6fccbb475b,
and this patch adds a new test case that reproduces this exact
scenario.

Markus Armbruster ba891d68b4 qstring: Move qstring_from_substr()'s @end one to the right
qstring_from_substr() takes the index of the substring's first and
last character.  qstring_from_substr(s, 0, SIZE_MAX) denotes an empty
substring.  Awkward.

Shift the end index one to the right.  This simplifies both
qstring_from_substr() and its callers.

Daniel P. Berrangé db0a8c70f2 tests: fix TLS handshake failure with TLS 1.3
When gnutls negotiates TLS 1.3 instead of 1.2, the order of messages
sent by the handshake changes. This exposed a logic bug in the test
suite which caused us to wait for the server to see handshake
completion, but not wait for the client to see completion. The result
was the client didn't receive the certificate for verification and the
test failed.

This is exposed in Fedora 29 rawhide which has just enabled TLS 1.3 in
its GNUTLS builds.

Daniel P. Berrangé 68db13183f tests: use error_abort in places expecting errors
Most of the TLS related tests are passing an in a "Error" object to
methods that are expected to fail, but then ignoring any error that is
set and instead asserting on a return value. This means that when an
error is unexpectedly raised, no information about it is printed out,
making failures hard to diagnose. Changing these tests to pass in
&error_abort will make unexpected failures print messages to stderr.

Daniel P. Berrangé 977a7204ab tests: don't silence error reporting for all tests
The test-vmstate test is a bit chatty because it triggers various
expected failure scenarios and the code in question uses error_report
instead of accepting 'Error **errp' parameters. To silence this test the
stubs for error_vprintf() were changed to send errors via
g_test_message() instead of stderr:

  commit 28017e010d
  Author: Paolo Bonzini <pbonzini@redhat.com>
  Date:   Mon Oct 24 18:31:03 2016 +0200

    tests: send error_report to test log

    Implement error_vprintf to send the output of error_report to
    the test log.  This silences test-vmstate.

    Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
    Message-Id: <1477326663-67817-3-git-send-email-pbonzini@redhat.com>

Unfortunately this change has global impact across the entire test suite
and means that when tests fail for unexpected reasons, the message is
not displayed on stderr. eg when using &error_abort in a call the test
merely prints

  Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280:

and the actual error message is hidden, making it impossible to diagnose
the failure. This is especially problematic in CI or build systems where
it isn't possible to easily pass the --debug-log flag to tests and
re-run with the test log visible.

This change makes the previous big hammer much more nuanced, providing a
flag in the stub error_vprintf() that can used on a per-test basis to
silence the errors. Only the test-vmstate silences errors initially.

Peter Xu 829db8b497 tests: only update last_byte when at the edge
The only possible change of last_byte is when it reaches the edge.
Setting it every time might let last_byte contain an invalid data when
memory corruption is detected, then the check of the next byte will be
incorrect.  For example, a single page corruption at address 0x14ad000
will also lead to a "fake" corruption at 0x14ae000:

  Memory content inconsistency at 14ad000 first_byte = 44 last_byte = 44 current = ef hit_edge = 0
  Memory content inconsistency at 14ae000 first_byte = 44 last_byte = ef current = 44 hit_edge = 0

After the patch, it'll only report the corrputed page:

  Memory content inconsistency at 14ad000 first_byte = 44 last_byte = 44 current = ef hit_edge = 0

the test will fail if the image format is part of the test directory,
like so:

[...]
-can't open: Could not open 'TEST_DIR/t.IMGFMT': Is a directory
+can't open: Could not open '/tmp/test-IMGFMT/t.IMGFMT': Is a directory
[...]

John Snow e05eb9f29b iotests: remove LUKS support from test 226
This test doesn't actually care about the format anyway, it just
supports "all formats" as a convenience. LUKS however does not use a
simple image filename which confuses this iotest.

We can simply skip the test for formats that use IMGOPTSSYNTAX for
their filenames without missing much coverage.

Peter Xu 62aa1d887f monitor: Fix unsafe sharing of @cur_mon among threads
@cur_mon is null unless the main thread is running monitor code, either
HMP code within monitor_read(), or QMP code within
monitor_qmp_dispatch().

Use of @cur_mon outside the main thread is therefore unsafe.

Most of its uses are in monitor command handlers.  These run in the main
thread.

However, there are also uses hiding elsewhere, such as in
error_vprintf(), and thus error_report(), making these functions unsafe
outside the main thread.  No such unsafe uses are known at this time.
Regardless, this is an unnecessary trap.  It's an ancient trap, though.

More recently, commit cf869d5317 "qmp: support out-of-band (oob)
execution" spiced things up: the monitor I/O thread assigns to @cur_mon
when executing commands out-of-band.  Having two threads save, set and
restore @cur_mon without synchronization is definitely unsafe.  We can
end up with @cur_mon null while the main thread runs monitor code, or
non-null while it runs non-monitor code.

We could fix this by making the I/O thread not mess with @cur_mon, but
that would leave the trap armed and ready.

Instead, make @cur_mon thread-local.  It's now reliably null unless the
thread is running monitor code.

Emanuele Giuseppe Esposito 9ee8a692f1 vhost-user-test: added proper TestServer *dest initialization in test_migrate()
server->bus in _test_server_free() could be NULL, since TestServer
*dest in test_migrate() was not properly initialized like TestServer *s.
Added init_virtio_dev(dest) and uninit_virtio_dev(dest), so the fields
are properly set and when test_server_free(dest); is called, they can
be correctly freed.

The reason for that is init_virtio_dev() calls qpci_init_pc(), that
creates a QPCIBusPC * (returned as QPCIBus *), while test_server_free()
calls qpci_free_pc(), that frees the QPCIBus *. Not calling
init_virtio_dev() would leave the QPCIBus * of TestServer unset.

Problem came out once I modified  pci-pc.c and pci-pc.h, modifying
QPCIBusPC by adding another field before QPCIBus bus. Re-running the
tests showed vhost-user-test failing.

Peter Lieven 8dcd3c9b91 qemu-img: align result of is_allocated_sectors
We currently don't enforce that the sparse segments we detect during convert are
aligned. This leads to unnecessary and costly read-modify-write cycles either
internally in Qemu or in the background on the storage device as nearly all
modern filesystems or hardware have a 4k alignment internally.

This patch modifies is_allocated_sectors so that its *pnum result will always
end at an alignment boundary. This way all requests will end at an alignment
boundary. The start of all requests will also be aligned as long as the results
of get_block_status do not lead to an unaligned offset.

The number of RMW cycles when converting an example image [1] to a raw device that
has 4k sector size is about 4600 4k read requests to perform a total of about 15000
write requests. With this path the additional 4600 read requests are eliminated while
the number of total write requests stays constant.

Kevin Wolf b0ddcbbb36 block: Fix copy-on-read crash with partial final cluster
If the virtual disk size isn't aligned to full clusters,
bdrv_co_do_copy_on_readv() may get pnum == 0 before having the full
cluster completed, which will let it run into an assertion failure:

qemu-io: block/io.c:1203: bdrv_co_do_copy_on_readv: Assertion `skip_bytes < pnum' failed.

Check for EOF, assert that we read at least as much as the read request
originally wanted to have (which is true at EOF because otherwise
bdrv_check_byte_request() would already have returned an error) and
return success early even though we couldn't copy the full cluster.

Alex Bennée 19c9a18f45 docker: add linux-user powered cross builder for QEMU
We can't use cross compilers in the current Debian stable and Debian
sid is sketchy as hell. So for powerpc fall back to dog-fooding our
own linux-user to do the build.

As we can only build the base image with a suitably configured
source tree we fall back to checking for its existence when we can't
build it from scratch. However this does mean you don't have to keep
a static powerpc-linux-user in your active configuration just to
update the cross build image.

Alex Bennée dc338fdb07 docker: add special rule for deboostrapped images
We might as well have a custom rule for this. For one thing the
dependencies are different. As the primary dependency for
docker-image-% could never be docker-image-debian-bootstrap we can
drop that test in the main rule as well.

Missing EXECUTABLE, DEB_ARCH and DEB_TYPE are treated as hard faults
now. We also error out if the EXECUTABLE file isn't there. We should
really do this with a dependency on any source rules but currently
subdir-FOO-linux-user isn't enough on a clean build.

Alex Bennée 547cb45ea3 docker: add special handling for FROM:debian-%-user targets
These will have been build with debootstrap so we need to check
against the debian-bootstrap dockerfile. This does mean sticking to
debian-FOO-user as the naming conventions for boot-strapped images.
The actual cross image is built on top.

Alex Bennée 300cf467fd docker: debian-bootstrap.pre allow customising of variant/url
We default to the buildd variant as most of our images are for
building. However lets give the user the ability to specify "minbase"
if they want to create a simple base image for experimentation.

Allowing the tweaking of DEB_URL means we can also bootstrap other
Debian based OS's. For example:

  make docker-binfmt-image-debian-ubuntu-bionic-arm64 \
       DEB_ARCH=arm64 DEB_TYPE=bionic \
       DEB_VARIANT=minbase DEB_URL=http://ports.ubuntu.com/ \
       EXECUTABLE=./aarch64-linux-user/qemu-aarch64

Philippe Mathieu-Daudé beac6a98f6 docker: ubuntu: Update the package list before installing new ones
Since docker caches the different layers, updating the package
list does not invalidate the previous "apt-get update" layer,
and it is likely "apt-get install" hits an outdated repository.

See https://docs.docker.com/develop/develop-images/dockerfile_best-practices/#apt-get

This fixes:

Kevin Wolf 824808dd77 block: Don't silently truncate node names
If the user passes a too long node name string, we silently truncate it
to fit into BlockDriverState.node_name, i.e. to 31 characters. Apart
from surprising the user when the node has a different name than
requested, this also bypasses the check for duplicate names, so that the
same name can be assigned to multiple nodes.

Fix this by just making too long node names an error.

Markus Armbruster 69240fe62d qmp: Don't let malformed in-band commands jump the queue
handle_qmp_command() reports certain errors right away.  This is wrong
when OOB is enabled, because the errors can "jump the queue" then, as
the previous commit demonstrates.

To fix, we need to delay errors until dispatch.  Do that for semantic
errors, mostly by reverting ill-advised parts of commit cf869d5317
"qmp: support out-of-band (oob) execution".  Bonus: doesn't run
qmp_dispatch_check_obj() twice, once in handle_qmp_command(), and
again in do_qmp_dispatch().  That's also due to commit cf869d5317.

The next commit will fix queue jumping for syntax errors.

Markus Armbruster e8f4a22168 tests/qmp-test: Demonstrate QMP errors jumping the queue
When OOB is enabled, out-of-band commands are executed right away,
everything else is queued.  This lets out-of-band commands "jump the
queue".

However, certain errors are always reported right away, and therefore
can jump the queue even when the erroneous input does not request
out-of-band execution.  These errors are pretty unlikely to occur in
production, but it's wrong all the same.  Mark FIXME.

Markus Armbruster 00ecec151d qmp: Redo how the client requests out-of-band execution
Commit cf869d5317 "qmp: support out-of-band (oob) execution" added a
general mechanism for command-independent arguments just for an
out-of-band flag:

    The "control" key is introduced to store this extra flag.  "control"
    field is used to store arguments that are shared by all the commands,
    rather than command specific arguments.  Let "run-oob" be the first.

However, it failed to reject unknown members of "control".  For
instance, in QMP command

    {"execute": "query-name", "id": 42, "control": {"crap": true}}

"crap" gets silently ignored.

Instead of fixing this, revert the general "control" mechanism
(because YAGNI), and do it the way I initially proposed, with key
"exec-oob".  Simpler code, simpler interface.

An out-of-band command

    {"execute": "migrate-pause", "id": 42, "control": {"run-oob": true}}

becomes

    {"exec-oob": "migrate-pause", "id": 42}

Markus Armbruster 674ed7228f qmp qemu-ga: Fix qemu-ga not to accept "control"
Commit cf869d5317 "qmp: support out-of-band (oob) execution"
accidentally made qemu-ga accept and ignore "control".  Fix that.

Out-of-band execution in a monitor that doesn't support it now fails
with

    {"error": {"class": "GenericError", "desc": "QMP input member 'control' is unexpected"}}

instead of

    {"error": {"class": "GenericError", "desc": "Please enable out-of-band first for the session during capabilities negotiation"}}

The old description is suboptimal when out-of-band cannot not be
enabled, or the command doesn't support out-of-band execution.

The new description is a bit unspecific, but it'll do.

Commit cf869d5317 "qmp: support out-of-band (oob) execution" changed
how we check "id":

    Note that in the patch I exported qmp_dispatch_check_obj() to be
    used to check the request earlier, and at the same time allowed
    "id" field to be there since actually we always allow that.

The part after "and" is ill-advised: it makes qemu-ga accept and
ignore "id".  Revert.

Markus Armbruster 97ca0712c8 qmp: Get rid of x-oob-test command
tests/qmp-test tests an out-of-band command overtaking a slow in-band
command.  To do that, it needs:

1. An in-band command that *reliably* takes long enough to be
   overtaken.

2. An out-of-band command to do the overtaking.

3. To avoid delays, a way to make the in-band command complete quickly
   after it was overtaken.

To satisfy these needs, commit 469638f9cb provides the rather
peculiar oob-capable QMP command x-oob-test:

* With "lock": true, it waits for a global semaphore.

* With "lock": false, it signals the global semaphore.

To satisfy 1., the test runs x-oob-test in-band with "lock": true.
To satisfy 2. and 3., it runs x-oob-test out-of-band with "lock": false.

Note that waiting for a semaphore violates the rules for oob-capable
commands.  Running x-oob-test with "lock": true hangs the monitor
until you run x-oob-test with "lock": false on another monitor (which
you might not have set up).

Having an externally visible QMP command that may hang the monitor is
not nice.  Let's apply a little more ingenuity to the problem.  Idea:
have an existing command block on reading a FIFO special file, unblock
it by opening the FIFO for writing.

For 1., use

    {"execute": "blockdev-add",  "id": ID1,
     "arguments": {
        "driver": "blkdebug", "node-name": ID1, "config": FIFO,
        "image": { "driver": "null-co"}}}

where ID1 is an arbitrary string, and FIFO is the name of the FIFO.

For 2., use

    {"execute": "migrate-pause", "id": ID2, "control": {"run-oob": true}}

where ID2 is a different arbitrary string.  Since there's no migration
to pause, the command will fail, but that's fine; instant failure is
still a test of out-of-band responses overtaking in-band commands.

For 3., open FIFO for writing.

Drop QMP command x-oob-test.

Richard W.M. Jones e1a6dc91dd crypto: Implement TLS Pre-Shared Keys (PSK).
Pre-Shared Keys (PSK) is a simpler mechanism for enabling TLS
connections than using certificates.  It requires only a simple secret
key:

  $ mkdir -m 0700 /tmp/keys
  $ psktool -u rjones -p /tmp/keys/keys.psk
  $ cat /tmp/keys/keys.psk
  rjones:d543770c15ad93d76443fb56f501a31969235f47e999720ae8d2336f6a13fcbc

The key can be secretly shared between clients and servers.  Clients
must specify the directory containing the "keys.psk" file and a
username (defaults to "qemu").  Servers must specify only the
directory.

Example NBD client:

  $ qemu-img info \
    --object tls-creds-psk,id=tls0,dir=/tmp/keys,username=rjones,endpoint=client \
    --image-opts \
    file.driver=nbd,file.host=localhost,file.port=10809,file.tls-creds=tls0,file.export=/

Example NBD server using qemu-nbd:

  $ qemu-nbd -t -x / \
    --object tls-creds-psk,id=tls0,endpoint=server,dir=/tmp/keys \
    --tls-creds tls0 \
    image.qcow2

Example NBD server using nbdkit:

  $ nbdkit -n -e / -fv \
    --tls=on --tls-psk=/tmp/keys/keys.psk \
    file file=disk.img

Eric Blake a1532a225a iotests: New test 223 for exporting dirty bitmap over NBD
Although this test is NOT a full test of image fleecing (as it
intentionally uses just a single block device directly exported
over NBD, rather than trying to set up a blockdev-backup job with
multiple BDS involved), it DOES prove that qemu as a server is
able to properly expose a dirty bitmap over NBD.

When coupled with image fleecing, it is then possible for a
third-party client to do an incremental backup by using
qemu-img map with the x-dirty-bitmap option to learn which parts
of the file are dirty (perhaps confusingly, they are the portions
mapped as "data":false - which is part of the reason this is
still in the x- experimental namespace), along with another
normal client (perhaps 'qemu-nbd -c' to expose the server over
/dev/nbd0 and then just use normal I/O on that block device) to
read the dirty sections.

Daniel P. Berrangé e71e8cc035 glib: enforce the minimum required version and warn about old APIs
There are two useful macros that can be defined before including
glib.h that are related to the min required glib version

 - GLIB_VERSION_MIN_REQUIRED

   When this is defined, if code uses an API that was deprecated
   in this version, or older, a compiler warning will be emitted.
   This alerts maintainers to update their code to whatever new
   replacement API is now recommended best practice.

 - GLIB_VERSION_MAX_ALLOWED

   When this is defined, if code uses an API that was introduced
   in a version that is newer than the declared version, a compiler
   warning will be emitted. This alerts maintainers if new code
   accidentally uses functionality that won't be available on some
   supported platforms.

The GLIB_VERSION_MAX_ALLOWED constant makes it a bit harder to opt
in to using specific new APIs with a GLIB_CHECK_VERSION conditional.
To workaround this Pragmas can be used to temporarily turn off the
-Wdeprecated-declarations compiler warning, while a static inline
compat function is implemented. This workaround is illustrated with the
implementation of the g_strv_contains method to satisfy the test suite.

Daniel P. Berrangé e7b3af8159 glib: bump min required glib library version to 2.40
Per supported platforms doc[1], the various min glib on relevant distros is:

  RHEL-7: 2.50.3
  Debian (Stretch): 2.50.3
  Debian (Jessie): 2.42.1
  OpenBSD (Ports): 2.54.3
  FreeBSD (Ports): 2.50.3
  OpenSUSE Leap 15: 2.54.3
  SLE12-SP2: 2.48.2
  Ubuntu (Xenial): 2.48.0
  macOS (Homebrew): 2.56.0

This suggests that a minimum glib of 2.42 is a reasonable target.

The GLibC compile farm, however, uses Ubuntu 14.04 (Trusty) which only
has glib 2.40.0, and this is needed for testing during merge. Thus an
exception is made to the documented platform support policy to allow for
all three current LTS releases to be supported.

Docker jobs that not longer satisfy this new min version are removed.

Thomas Huth 28a3cfc10b tests/boot-serial: Do not delete the output file in case of errors
Peter reported that the boot-serial tester sometimes runs into timeouts
with SPARC guests. It's currently completely unclear whether this is due
to too much load on the host machine (so that the guest really just ran
too slow), or whether there is something wrong with the guest's firmware
boot. For further debugging, we need the serial output of the guest in
case of errors, so instead of unlinking the file immediately, this is
now only done in case of success. In case of error, print the name of the
file with the serial output via g_error() (which then also calls abort()
internally to mark the test as failed).

Paolo Bonzini ae79c2db15 ahci: fix FIS I bit and PIO Setup FIS interrupt
The "I" bit in PIO Setup and D2H FISes is exclusively a device concept
and the irqstatus register in the controller does not matter.  The SATA
spec says when it should be one; for D2H FISes in practice it is always
set, while the PIO Setup FIS has several subcases that are documented in
the patch.

Also, the PIO Setup FIS interrupt is actually generated _after_ data
has been received.

Someone should probably spend some time reading the SATA specification and
figuring out the more obscure fields in the PIO Setup FIS, but this is enough
to fix SeaBIOS booting from ATAPI CD-ROMs over an AHCI controller.

This commit removes the PYTHON_UTF8 workaround. The problem with setting

  LC_ALL= LANG=C LC_CTYPE=en_US.UTF-8

is that the en_US.UTF-8 locale might not be available. In this case
setting above locales results in build errors even though another UTF-8
locale was originally set [1]. The only stable way of fixing the
encoding problem is by specifying the encoding in Python, like the

Anton Nefedov 800877bb16 qapi: allow empty branches in flat unions
It often happens that just a few discriminator values imply extra data in
a flat union. Existing checks did not make possible to leave other values
uncovered. Such cases had to be worked around by either stating a dummy
(empty) type or introducing another (subset) discriminator enumeration.

Both options create redundant entities in qapi files for little profit.

With this patch it is not necessary anymore to add designated union
fields for every possible value of a discriminator enumeration.

Eric Blake ac5de4984d tests: Simplify .gitignore
Commit 0bcc8e5b was yet another instance of 'git status' reporting
dirty files after an in-tree build, thanks to the new binary
tests/check-block-qdict.

Instead of piecemeal exemptions of each new binary as they are
added, let's use git's negative globbing feature to exempt ALL
files that have a 'test-' or 'check-' prefix, except for the ones
ending in '.c' or '.sh'.  We still have a couple of generated
files that then need (re-)exclusion, but the overall list is a
LOT shorter, and less prone to needing future edits.

Alex Bennée 1a7fab926b tests: add top-level make dependency for docker builds
One problem with satisfying your docker dependencies in a sub-make it
you might end up trying to satisfy the dependency multiple times. This
is especially a problem with debian-sid based cross compilers and CI
setups. We solve this by doing a docker build pass at the top level
before any sub-makes are called.

We still need to satisfy dependencies in the Makefile.target call so
people can run tests from individual target directories. We introduce
a new Makefile.probe which gets called for each PROBE_TARGET and
allows us to build up the list. It does require multiply including
config-target.mak which shouldn't cause any issues as it shouldn't
define anything that clashes with config-host.mak. However we undefine
a few key variables each time around.

This make is now invoked from each individual target make with the

additional Makefile.targets from:

  - tests/tcg/multiarch (always)
  - tests/tcg/$(TARGET_BASE_ARCH) (if available)

The order is important as the later Makefile's may want to suppress
TESTS from its base arch profile. Each included Makefile.target is
responsible for adding TESTS as well as defining any special build
instructions for individual tests.

Max Reitz 269576848e test-hbitmap: Add non-advancing iter_next tests
Add a function that wraps hbitmap_iter_next() and always calls it in
non-advancing mode first, and in advancing mode next.  The result should
always be the same.

By using this function everywhere we called hbitmap_iter_next() before,
we should get good test coverage for non-advancing hbitmap_iter_next().

Max Reitz 4c8158e359 test-bdrv-drain: Add test for node deletion
This patch adds two bdrv-drain tests for what happens if some BDS goes
away during the drainage.

The basic idea is that you have a parent BDS with some child nodes.
Then, you drain one of the children.  Because of that, the party who
actually owns the parent decides to (A) delete it, or (B) detach all its
children from it -- both while the child is still being drained.

A real-world case where this can happen is the mirror block job, which
may exit if you drain one of its children.

Kevin Wolf 89bd030533 block: Really pause block jobs on drain
We already requested that block jobs be paused in .bdrv_drained_begin,
but no guarantee was made that the job was actually inactive at the
point where bdrv_drained_begin() returned.

This introduces a new callback BdrvChildRole.bdrv_drained_poll() and
uses it to make bdrv_drain_poll() consider block jobs using the node to
be drained.

For the test case to work as expected, we have to switch from
block_job_sleep_ns() to qemu_co_sleep_ns() so that the test job is even
considered active and must be waited for when draining the node.

Kevin Wolf 6d0252f2f9 tests/test-bdrv-drain: bdrv_drain_all() works in coroutines now
Since we use bdrv_do_drained_begin/end() for bdrv_drain_all_begin/end(),
coroutine context is automatically left with a BH, preventing the
deadlocks that made bdrv_drain_all*() unsafe in coroutine context. Now
that we even removed the old polling code as dead code, it's obvious
that it's compatible now.

Enable the coroutine test cases for bdrv_drain_all().

Kevin Wolf 79ab8b21dc block: Use bdrv_do_drain_begin/end in bdrv_drain_all()
bdrv_do_drain_begin/end() implement already everything that
bdrv_drain_all_begin/end() need and currently still do manually: Disable
external events, call parent drain callbacks, call block driver
callbacks.

It also does two more things:

The first is incrementing bs->quiesce_counter. bdrv_drain_all() already
stood out in the test case by behaving different from the other drain
variants. Adding this is not only safe, but in fact a bug fix.

The second is calling bdrv_drain_recurse(). We already do that later in
the same function in a loop, so basically doing an early first iteration
doesn't hurt.

Kevin Wolf bb67568954 test-bdrv-drain: bdrv_drain() works with cross-AioContext events
As long as nobody keeps the other I/O thread from working, there is no
reason why bdrv_drain() wouldn't work with cross-AioContext events. The
key is that the root request we're waiting for is in the AioContext
we're polling (which it always is for bdrv_drain()) so that aio_poll()
is woken up in the end.

Add a test case that shows that it works. Remove the comment in
bdrv_drain() that claims otherwise.

Cleber Rosa c1cc73f407 Acceptance tests: add Linux kernel boot and console checking test
This test boots a Linux kernel, and checks that the given command
line was effective in two ways:

 * It makes the kernel use the set "console device" as a console
 * The kernel records the command line as expected in the console

Given that way too many error conditions may occur, and detecting the
kernel boot progress status may not be trivial, this test relies on a
timeout to handle unexpected situations.  Also, it's *not* tagged as a
quick test for obvious reasons.

It may be useful, while interactively running/debugging this test, or
tests similar to this one, to show some of the logging channels.
Example:

 $ avocado --show=QMP,console run boot_linux_console.py

Emilio G. Cota 61b8cef1d4 qht: require a default comparison function
qht_lookup now uses the default cmp function. qht_lookup_custom is defined
to retain the old behaviour, that is a cmp function is explicitly provided.

qht_insert will gain use of the default cmp in the next patch.

Note that we move qht_lookup_custom's @func to be the last argument,
which makes the new qht_lookup as simple as possible.
Instead of this (i.e. keeping @func 2nd):
0000000000010750 <qht_lookup>:
   10750:       89 d1                   mov    %edx,%ecx
   10752:       48 89 f2                mov    %rsi,%rdx
   10755:       48 8b 77 08             mov    0x8(%rdi),%rsi

   1075e:       66 90                   xchg   %ax,%ax

We get:

Markus Armbruster 2860b2b2cb block: Fix -blockdev / blockdev-add for empty objects and arrays
-blockdev and blockdev-add silently ignore empty objects and arrays in
their argument.  That's because qmp_blockdev_add() converts the
argument to a flat QDict, and qdict_flatten() eats empty QDict and
QList members.  For instance, we ignore an empty BlockdevOptions
member @cache.  No real harm, as absent means the same as empty there.

Thus, the flaw puts an artificial restriction on the QAPI schema: we
can't have potentially empty objects and arrays within
BlockdevOptions, except when they're optional and "empty" has the same
meaning as "absent".

Our QAPI schema satisfies this restriction (I checked), but it's a
trap for the unwary, and a temptation to employ awkward workarounds
for the wary.  Let's get rid of it.

Change qdict_flatten() and qdict_crumple() to treat empty dictionaries
and lists exactly like scalars.

There are numerous QDict functions that have been introduced for and are
used only by the block layer.  Move their declarations into an own
header file to reflect that.

While qdict_extract_subqdict() is in fact used outside of the block
layer (in util/qemu-config.c), it is still a function related very
closely to how the block layer works with nested QDicts, namely by
sometimes flattening them.  Therefore, its declaration is put into this
header as well and util/qemu-config.c includes it with a comment stating
exactly which function it needs.

Test that the bug fixed in the previous patch does not recur.

It's a bit annoying that we can see the (implicit) hole past
the end of the file on to the next sector boundary, so if we
ever reach the point where we report a byte-accurate size rather
than our current behavior of always rounding up, this test will
probably need a slight modification.

Ross Zwisler 0f3ef1c062 hw/i386: Update SSDT table used by "make check"
This commit:

commit aa78a16d86 ("hw/i386: Rename 2.13 machine types to 3.0")

updated the name used to create the q35 machine, which in turn changed the
SSDT table which is generated when we run "make check":

  acpi-test: Warning! SSDT mismatch. Actual [asl:/tmp/asl-QZDWJZ.dsl,
  aml:/tmp/aml-T8JYJZ], Expected [asl:/tmp/asl-DTWVJZ.dsl,
  aml:tests/acpi-test-data/q35/SSDT.dimmpxm].

Here's the only difference, aside from the checksum:

  <     Name (MEMA, 0x07FFF000)
  ---
  >     Name (MEMA, 0x07FFE000)

Update the binary table that we compare against so it reflects this name
change.

Max Reitz 83f90b535a iotests: Fix 219's timing
219 has two issues that may lead to sporadic failure, both of which are
the result of issuing query-jobs too early after a job has been
modified.  This can then lead to different results based on whether the
modification has taken effect already or not.

First, query-jobs is issued right after the job has been created.
Besides its current progress possibly being in any random state (which
has already been taken care of), its total progress too is basically
arbitrary, because the job may not yet have been able to determine it.
This patch addresses this by just filtering the total progress, like
what has been done for the current progress already.  However, for more
clarity, the filtering is changed to replace the values by a string
'FILTERED' instead of deleting them.

Secondly, query-jobs is issued right after a job has been resumed.  The
job may or may not yet have had the time to actually perform any I/O,
and thus its current progress may or may not have advanced.  To make
sure it has indeed advanced (which is what the reference output already
assumes), keep querying it until it has.

Max Reitz e4ca4e981a iotests: Let 216 make use of qemu-io's exit code
As a showcase of how you can use qemu-io's exit code to determine
success or failure (same for qemu-img), this test is changed to use
qemu_io_silent() instead of qemu_io(), and to assert the exit code
instead of logging the filtered result.

One real advantage of this is that in case of an error, you get a
backtrace that helps you locate the issue in the test file quickly.

This adds a test for an I/O error during snapshot deletion, and maybe

Max Reitz dee6ddd8a6 iotests: Rework 113
This test case has been broken since 398e6ad014 (roughly half a
year).  qemu-img amend requires its output image to be R/W, so it opens
it as such; the node is then turned into an read-only node automatically
which is now accompanied by a warning, however.  This warning has not
been part of the reference output.

For one thing, this warning shows that we cannot keep the test case as
it is.  We would need a format that has no create_opts but that does
have write support -- we do not have such a format, though.

Another thing is that qemu now actually checks whether an image format
supports amendment instead of whether it has create_opts (since the
former always implies the latter).  So we can now use any format that
does not support amendment (even if it supports creation) and thus test
the same code path.

The reason nobody has noticed the breakage until now of course is the
fact that nobody runs the iotests for nbd+bochs.  There actually was
never any reason to set the protocol to "nbd" but because that was
technically correct; functionally it made no difference.  So that is the
first thing we are going to change: Make the protocol "file" instead so
that people might actually notice breakage here.

Secondly, now that bochs no longer works for the amend test case, we
have to change the format there anyway.  Set let us just bend the truth
a bit, declare this test a raw test.  In fact, that does not even
concern the bochs test cases, other than the output now reading 'bochs'
instead of 'IMGFMT'.

So with this test now being a raw test, we can rework the amend test
case to use raw instead.

Max Reitz 5164135142 qemu-img: Add print_amend_option_help()
The more generic print_block_option_help() function is not really
suitable for qemu-img amend, for a couple of reasons:
(1) We do not need to append the protocol-level options, as amendment
    happens only on one node and does not descend downwards to its
    children.
(2) print_block_option_help() says those options are "supported".  For
    option amendment, we do not really know that.  So this new function
    explicitly says that those options are the creation options, and not
    all of them may be supported.
(3) If the driver does not support option amendment, we should not print
    anything (except for an error message that amendment is not
    supported).

John Snow 956556e131 ahci: move PIO Setup FIS before transfer, fix it for ATAPI commands
The PIO Setup FIS is written in the PIO:Entry state, which comes before
the ATA and ATAPI data transfer states.  As a result, the PIO Setup FIS
interrupt is now raised before DMA ends for ATAPI commands, and tests have
to be adjusted.

This is also hinted by the description of the command header in the AHCI
specification, where the "A" bit is described as

    When ‘1’, indicates that a PIO setup FIS shall be sent by the device
    indicating a transfer for the ATAPI command.

and also by the description of the ACMD (ATAPI command region):

    The ATAPI command must be either 12 or 16 bytes in length. The length
    transmitted by the HBA is determined by the PIO setup FIS that is sent
    by the device requesting the ATAPI command.

QEMU, which conflates the "generator" and the "receiver" of the FIS into
one device, always uses ATAPI_PACKET_SIZE, aka 12, for the length.

John Snow 27e4648ce9 libqos/ahci: track sector size
It's not always 512, and it does wind up mattering for PIO tranfers,
because this means DRQ blocks are four times as big for ATAPI.
Replace an instance of 2048 with the correct define, too.

This patch by itself winds changing no behavior. fis->count is ignored
for CMD_PACKET, and sect_count only gets used in non-ATAPI cases.

Thomas Huth 49d43a5978 tests/cdrom-test: Test that -cdrom parameter is working
Commit 1454509726 recently broke the "-cdrom" parameter
on a couple of boards without us noticing it immediately. Thus let's
add a test which checks that "-cdrom" can at least be used to start
QEMU with certain machine types.

Thomas Huth 42f455054f tests/cdrom-test: Test booting from CD-ROM ISO image file
We already have the code for a boot file in tests/boot-sector.c,
so if the genisoimage program is available, we can easily create
a bootable CD ISO image that we can use for testing whether our
CD-ROM emulation and the BIOS CD-ROM boot works correctly.

Thomas Huth b1dd6d2d27 tests/boot-sector: Add magic bytes to s390x boot code header
We're going to use the s390x boot code for testing CD-ROM booting.
But the ISO loader of the s390-ccw bios is a little bit more picky
than the network loader and expects some magic bytes in the header
of the file (see linux_s390_magic in pc-bios/s390-ccw/bootmap.c), so
we've got to add them in our boot code here, too.
