Markus Armbruster f332e830e3 qapi: Make string input and opts visitor require non-null input
The string input visitor tries to cope with null input.  Null input
isn't used anywhere, and isn't covered by tests.  Unsurprisingly, it
doesn't fully work: start_list() crashes because it passes the input
via parse_str() to strtoll() unchecked.

Make string_input_visitor_new() assert its argument isn't null, and
drop the code trying to deal with null input.

The opts visitor crashes when you try to actually visit something with
null input.  Make opts_visitor_new() assert its argument isn't null,
mostly for clarity.

qobject_input_visitor_new() already asserts its argument isn't null.

Markus Armbruster a8aec6de2a qapi: Drop string input visitor method optional()
visit_optional() is to be called only between visit_start_struct() and
visit_end_struct().  Visitors that don't support struct visits,
i.e. don't implement start_struct(), end_struct(), have no use for it.
Clarify documentation.

The string input visitor doesn't support struct visits.  Its
parse_optional() is therefore useless.  Drop it.

Markus Armbruster a9fc37f6bc qapi: Improve qobject input visitor error reporting
Error messages refer to nodes of the QObject being visited by name.
Trouble is the names are sometimes less than helpful:

* The name of the root QObject is whatever @name argument got passed
  to the visitor, except NULL gets mapped to "null".  We commonly pass
  NULL.  Not good.

  Avoiding errors "at the root" mitigates.  For instance,
  visit_start_struct() can only fail when the visited object is not a
  dictionary, and we commonly ensure it is beforehand.

* The name of a QDict's member is the member key.  Good enough only
  when this happens to be unique.

* The name of a QList's member is "null".  Not good.

Improve error messages by referring to nodes by path instead, as
follows:

* The path of the root QObject is whatever @name argument got passed
  to the visitor, except NULL gets mapped to "<anonymous>".

* The path of a root QDict's member is the member key.

* The path of a root QList's member is "[%u]", where %u is the list
  index, starting at zero.

* The path of a non-root QDict's member is the path of the QDict
  concatenated with "." and the member key.

* The path of a non-root QList's member is the path of the QList
  concatenated with "[%u]", where %u is the list index.

For example, the incorrect QMP command

    { "execute": "blockdev-add", "arguments": { "node-name": "foo", "driver": "raw", "file": {"driver": "file" } } }

now fails with

    {"error": {"class": "GenericError", "desc": "Parameter 'file.filename' is missing"}}

instead of

    {"error": {"class": "GenericError", "desc": "Parameter 'filename' is missing"}}

and

    { "execute": "input-send-event", "arguments": { "device": "bar", "events": [ [] ] } }

now fails with

    {"error": {"class": "GenericError", "desc": "Invalid parameter type for 'events[0]', expected: object"}}

instead of

    {"error": {"class": "GenericError", "desc": "Invalid parameter type for 'null', expected: QDict"}}

Aside: calling the thing "parameter" is suboptimal for QMP, because
the root object is "arguments" there.

The qobject output visitor doesn't have this problem because it should
not fail.  Same for dealloc and clone visitors.

The string visitors don't have this problem because they visit just
one value, whose name needs to be passed to the visitor as @name.  The
string output visitor shouldn't fail anyway.

The options visitor uses QemuOpts names.  Their name space is flat, so
the use of QDict member keys as names is fine.  NULL names used with
roots and lists could conceivably result in bad error messages.  Left
for another day.

Markus Armbruster 58561c2766 qapi: Make QObject input visitor set *list reliably
qobject_input_start_struct() sets *list, except when it fails because
qobject_input_get_object() fails, i.e. the input object doesn't exist.

All the other input visitor start_struct(), start_list(),
start_alternate() always set *obj / *list.

Change qobject_input_start_struct() to match.

Markus Armbruster 910f738b85 qapi: Improve a QObject input visitor error message
The QObject input visitor has three error message formats:

* Parameter '%s' is missing
* "Invalid parameter type for '%s', expected: %s"
* "QMP input object member '%s' is unexpected"

The '%s' are member names (or "null", but I'll fix that later).

The last error message calls the thing "QMP input object member"
instead of "parameter".  Misleading when the visitor is used on
QObjects that don't come from QMP.  Change it to "Parameter '%s' is
unexpected".

Markus Armbruster 104fc30279 qmp: Drop duplicated QMP command object checks
qmp_check_input_obj() duplicates qmp_dispatch_check_obj(), except the
latter screws up an error message.  handle_qmp_command() runs first
the former, then the latter via qmp_dispatch(), masking the screwup.

qemu-ga also masks the screwup, because it also duplicates checks,
just differently.

qmp_check_input_obj() exists because handle_qmp_command() needs to
examine the command before dispatching it.  The previous commit got
rid of this need, except for a tracepoint, and a bit of "id" code that
relies on qdict not being null.

Fix up the error message in qmp_dispatch_check_obj(), drop
qmp_check_input_obj() and the tracepoint.  Protect the "id" code with
a conditional.

Markus Armbruster 74d8c9d99d qga: Fix crash on non-dictionary QMP argument
The value of key 'arguments' must be a JSON object.  qemu-ga neglects
to check, and crashes.  To reproduce, send

    { 'execute': 'guest-sync', 'arguments': [] }

to qemu-ga.

do_qmp_dispatch() uses qdict_get_qdict() to get the arguments.  When
not a JSON object, this gets a null pointer, which flows through the
generated marshalling function to qobject_input_visitor_new(), where
it fails the assertion.  qmp_dispatch_check_obj() needs to catch this
error.

QEMU isn't affected, because it runs qmp_check_input_obj() first,
which basically duplicates qmp_dispatch_check_obj()'s checks, plus the
missing one.

Fix by copying the missing one from qmp_check_input_obj() to
qmp_dispatch_check_obj().

Change the qemu_strtosz() & friends to return -EINVAL when @endptr is

Matches how qemu_strtol() & friends work.

Only test_qemu_strtosz_simple() passes a null @endptr.  No functional
change there, because its conversion consumes the string.

Simplify callers that use @endptr only to fail when it doesn't point
to '\0' to pass a null @endptr instead.

Stefan Hajnoczi 7f4076c1bb trace: clean up trace-events files
There are a number of unused trace events that
scripts/cleanup-trace-events.pl finds.  The "hw/vfio/pci-quirks.c"
filename was typoed and "qapi/qapi-visit-core.c" was missing the qapi/
directory prefix.

Stefan Hajnoczi 6514532f73 qapi: add missing trace_visit_type_enum() call
A trace event exists for enums but it's never called.  This patch fixes
this oversight so that enums are traced just like the other QAPI types.

Eric Blake 4230e5d128 qapi: Document introduction of gluster's 'debug' option
We intentionally renamed 'debug-level' to 'debug' in the QMP
schema for 'blockdev-add' related to gluster, in order to
match the command line (commit 1a417e46).  However, since
'debug-level' was visible in 2.7, that means that we should
document that 'debug' was not available until 2.8.

The change was intentional because 'blockdev-add' itself
underwent incompatible changes (such as commit 0153d2f) for
the same release; our intent is that after 2.8, these
interfaces will now be stable.  [In hindsight, we should have
used the name x-blockdev-add when we first introduced it]

Eric Blake 043b5a4951 qmp-event: Avoid qobject_from_jsonf("%"PRId64)
The qobject_from_jsonf() function implements a pseudo-printf
language for creating a QObject; however, it is hard-coded to
only parse a subset of formats understood by -Wformat, and is
not a straight synonym to bare printf().  In particular, any
use of an int64_t integer works only if the system's
definition of PRId64 matches what the parser expects; which
works on glibc (%lld or %ld depending on 32- vs. 64-bit) and
mingw (%I64d), but not on Mac OS (%qd).  Rather than enhance
the parser, it is just as easy to use 'long long', which we
know always works.  There are few enough callers of
qobject_from_json[fv]() that it is easy to audit that this is
the only non-testsuite caller that was actually relying on
this particular conversion.

Max Reitz 23dce3873f block/curl: Drop TFTP "support"
Because TFTP does not support byte ranges, it was never usable with our
curl block driver. Since apparently nobody has ever complained loudly
enough for someone to take care of the issue until now, it seems
reasonable to assume that nobody has ever actually used it.

Therefore, it should be safe to just drop it from curl's protocol list.

[Jeff Cody: Below is additional summary pulled, with some rewording,
            from followup emails between Max and Markus, to explain what
            worked and what didn't]

TFTP would sometimes work, to a limited extent, for images <= the curl
"readahead" size, so long as reads started at offset zero.  By default,
that readahead size is 256KB.

Reads starting at a non-zero offset would also have returned data from a
zero offset.  It can become more complicated still, with mixed reads at
zero offset and non-zero offsets, due to data buffering.

In short, TFTP could only have worked before in very specific scenarios
with unrealistic expectations and constraints.

Kevin Wolf 2d76e724cf block: Add qdev ID to DEVICE_TRAY_MOVED
The event currently only contains the BlockBackend name. However, with
anonymous BlockBackends, this is always the empty string. Add the qdev
ID (or if none was given, the QOM path) so that the user can still see
which device caused the event.

Event generation has to be moved from bdrv_eject() to the BlockBackend
because the BDS doesn't know the attached device, but that's easy
because blk_eject() is the only user of it.

Kevin Wolf 0a4279d97c block/qapi: Move 'aio' option to file driver
The option whether or not to use a native AIO interface really isn't a
generic option for all drivers, but only applies to the native file
protocols. This patch moves the option in blockdev-add to the
appropriate places (raw-posix and raw-win32).

We still have to keep the flag BDRV_O_NATIVE_AIO for compatibility
because so far the AIO option was usually specified on the wrong layer
(the top-level format driver, which didn't even look at it) and then
inherited by the protocol driver (where it was actually used). We can't
forbid this use except in new interfaces.

Daniel P. Berrange 3bd18890ca crypto: make PBKDF iterations configurable for LUKS format
As protection against bruteforcing passphrases, the PBKDF
algorithm is tuned by counting the number of iterations
needed to produce 1 second of running time. If the machine
that the image will be used on is much faster than the
machine where the image is created, it can be desirable
to raise the number of iterations. This change adds a new
'iter-time' property that allows the user to choose the
iteration wallclock time.

Prasanna Kumar Kalever e9db8ff38e block/gluster: add support to choose libgfapi logfile
currently all the libgfapi logs defaults to '/dev/stderr' as it was hardcoded
in a call to glfs logging api. When the debug level is chosen to DEBUG/TRACE,
gfapi logs will be huge and fill/overflow the console view.

This patch provides a commandline option to mention log file path which helps
in logging to the specified file and also help in persisting the gfapi logs.

Usage:
-----
 *URI Style:
  ---------
  -drive file=gluster://hostname/volname/image.qcow2,file.debug=9,\
                      file.logfile=/var/log/qemu/qemu-gfapi.log

 *JSON Style:
  ----------
  'json:{
           "driver":"qcow2",
           "file":{
              "driver":"gluster",
              "volume":"volname",

Pavel Butsykin 13b9414b57 drive-backup: added support for data compression
The idea is simple - backup is "written-once" data. It is written block
by block and it is large enough. It would be nice to save storage
space and compress it.

The patch adds a flag to the qmp/hmp drive-backup command which enables
block compression. Compression should be implemented in the format driver
to enable this feature.

There are some limitations of the format driver to allow compressed writes.
We can write data only once. Though for backup this is perfectly fine.
These limitations are maintained by the driver and the error will be
reported if we are doing something wrong.

Kevin Wolf 094138d09e nbd-server: Allow node name for nbd-server-add
There is no reason why an NBD server couldn't be started for any node,
even if it's not on the top level. This converts nbd-server-add to
accept a node-name.

Note that there is a semantic difference between using a BlockBackend
name and the node name of its root: In the former case, the NBD server
is closed on eject; in the latter case, the NBD server doesn't drop its
reference and keeps the image file open this way.

One somewhat undesirable artifact is that the data fields are

later by changing the way the block layer pretty-prints the

Prasanna Kumar Kalever 6c7189bb29 block/gluster: add support for multiple gluster servers
This patch adds a way to specify multiple volfile servers to the gluster
block backend of QEMU with tcp|rdma transport types and their port numbers.

Problem:

Currently VM Image on gluster volume is specified like this:

file=gluster[+tcp]://host[:port]/testvol/a.img

Say we have three hosts in a trusted pool with replica 3 volume in action.
When the host mentioned in the command above goes down for some reason,
the other two hosts are still available. But there's currently no way
to tell QEMU about them.

Solution:

New way of specifying VM Image on gluster volume with volfile servers:
(We still support old syntax to maintain backward compatibility)

Basic command line syntax looks like:

Pattern I:
 -drive driver=gluster,
        volume=testvol,path=/path/a.raw,[debug=N,]
        server.0.type=tcp,
        server.0.host=1.2.3.4,
        server.0.port=24007,
        server.1.type=unix,
        server.1.socket=/path/socketfile

Pattern II:
 'json:{"driver":"qcow2","file":{"driver":"gluster",
       "volume":"testvol","path":"/path/a.qcow2",["debug":N,]
       "server":[{hostinfo_1}, ...{hostinfo_N}]}}'

   driver      => 'gluster' (protocol name)
   volume      => name of gluster volume where our VM image resides
   path        => absolute path of image in gluster volume
  [debug]      => libgfapi loglevel [(0 - 9) default 4 -> Error]

  {hostinfo}   => {{type:"tcp",host:"1.2.3.4"[,port=24007]},
                   {type:"unix",socket:"/path/sockfile"}}

   type        => transport type used to connect to gluster management daemon,
                  it can be tcp|unix
   host        => host address (hostname/ipv4/ipv6 addresses/socket path)
   port        => port number on which glusterd is listening.
   socket      => path to socket file

Examples:
1.
 -drive driver=qcow2,file.driver=gluster,
        file.volume=testvol,file.path=/path/a.qcow2,file.debug=9,
        file.server.0.type=tcp,
        file.server.0.host=1.2.3.4,
        file.server.0.port=24007,
        file.server.1.type=unix,
        file.server.1.socket=/var/run/glusterd.socket
2.
  'json:{"driver":"qcow2","file":{"driver":"gluster","volume":"testvol",
         "path":"/path/a.qcow2","debug":9,"server":
         [{"type":"tcp","host":"1.2.3.4","port":"24007"},
          {"type":"unix","socket":"/var/run/glusterd.socket"}
         ]}}'

This patch gives a mechanism to provide all the server addresses, which are in
replica set, so in case host1 is down VM can still boot from any of the
active hosts.

This is equivalent to the backup-volfile-servers option supported by
mount.glusterfs (FUSE way of mounting gluster volume)

Paolo Bonzini 3d344c2aab qapi: change QmpInputVisitor to QSLIST
This saves a lot of memory compared to a statically-sized array,
or at least 24kb could be considered a lot on an Atari ST.
It also makes the code more similar to QmpOutputVisitor.

This removes the limit on the depth of a QObject that can be processed
into a QAPI tree.  This is not a problem because QObjects can be
considered trusted; the text received on the QMP wire is untrusted
input, but the JSON parser already takes pains to limit the QObject tree
it creates.  We don't need the QMP input visitor to limit it again.

Kevin Wolf 35fedb7b0e block: Remove BB options from blockdev-add
werror/rerror are now available as qdev options. The stats-* options are
removed without an existing replacement; they should probably be
configurable with a separate QMP command like I/O throttling settings.

Removing id is left for another day because this involves updating
qemu-iotests cases to use node-name for everything. Before we can do
that, however, all QMP commands must support node-name.

If the option isn't given (or "auto" is specified), the setting of the

Eric Blake a15fcc3cf6 qapi: Add new clone visitor
We have a couple places in the code base that want to deep-clone
one QAPI object into another, and they were resorting to serializing
the struct out to QObject then reparsing it.  A much more efficient
version can be done by adding a new clone visitor.

Since cloning is still relatively uncommon, expose the use of the
new visitor via a QAPI_CLONE() macro that takes care of type-punning
the underlying function pointer, rather than generating lots of
unused functions for types that won't be cloned.  And yes, we're
relying on the compiler treating all pointers equally, even though
a strict C program cannot portably do so - but we're not the first
one in the qemu code base to expect it to work (hello, glib!).

The choice of adding a fourth visitor type deserves some explanation.
On the surface, the clone visitor is mostly an input visitor (it
takes arbitrary input - in this case, another QAPI object - and
creates a new QAPI object during the course of the visit).  But
ever since commit da72ab0 consolidated enum visits based on the
visitor type, using VISITOR_INPUT would cause us to run
visit_type_str(), even though for cloning there is nothing to do
(we just copy the enum value across, without regards to its mapping
to strings).   Also, since our input happens to be a QAPI object,
we can also satisfy the internal checks for VISITOR_OUTPUT.  So in
the end, I settled with a new VISITOR_CLONE, and chose its value
such that many internal checks can use 'v->type & mask', sticking
to 'v->type == value' where the difference matters.

Note that we can only clone objects (including alternates) and lists,
not built-ins or enums.  The visitor core hides integer width from
the actual visitor (since commit 04e070d), and as long as that's the
case, we can't clone top-level integers.  Then again, those can
always be cloned by direct copy, since they are not objects with
deep pointers, so it's no real loss.  And restricting cloning to
just objects and lists is cleaner than restricting it to non-integers.
As such, I documented that the clone visitor is for direct use only
by code internal to QAPI, and should not be used on incomplete objects
(other than a hack to work around the fact that we allow NULL in place
of "" in visit_type_str() in other output visitors).  Note that as
written, the clone visitor will never fail on a complete object.

Scalars (including enums) not at the root of the clone copy just fine
with no additional effort while visiting the scalar, by virtue of a
g_memdup() each time we push another struct onto the stack.  Cloning
a string requires deduplication of a pointer, which means it can also
provide the guarantee of an input visitor of never producing NULL
even when still accepting NULL in place of "" the way the QMP output
visitor does.

Cloning an 'any' type could be possible by incrementing the QObject
refcnt, but it's not obvious whether that is better than implementing
a QObject deep clone.  So for now, we document it as unsupported,
and intentionally omit the .type_any() callback to let a developer
know their usage needs implementation.

Add testsuite coverage for several different clone situations, to
ensure that the code is working.  I also tested that valgrind was
happy with the test.

Eric Blake 3b098d5697 qapi: Add new visit_complete() function
Making each output visitor provide its own output collection
function was the only remaining reason for exposing visitor
sub-types to the rest of the code base.  Add a polymorphic
visit_complete() function which is a no-op for input visitors,
and which populates an opaque pointer for output visitors.  For
maximum type-safety, also add a parameter to the output visitor
constructors with a type-correct version of the output pointer,
and assert that the two uses match.

This approach was considered superior to either passing the
output parameter only during construction (action at a distance
during visit_free() feels awkward) or only during visit_complete()
(defeating type safety makes it easier to use incorrectly).

Most callers were function-local, and therefore a mechanical
conversion; the testsuite was a bit trickier, but the previous
cleanup patch minimized the churn here.

The visit_complete() function may be called at most once; doing
so lets us use transfer semantics rather than duplication or
ref-count semantics to get the just-built output back to the
caller, even though it means our behavior is not idempotent.
