2018-08-16qobject: qobject_from_jsonv() is dangerous, hide it awayMarkus Armbruster1-2/+0
qobject_from_jsonv() takes ownership of %p arguments. On failure, we can't generally know whether we failed before or after %p, so ownership becomes indeterminate. To avoid leaks, callers passing %p must terminate on error, e.g. by passing &error_abort. Trap for the unwary; document and give the function internal linkage.

2018-08-16qobject: Replace qobject_from_jsonf() by qobject_from_jsonf_nofail()Markus Armbruster1-2/+4
Commit ab45015a968 "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().

2018-07-28qstring: Fix qstring_from_substr() not to provoke int overflowliujunjie1-1/+1
qstring_from_substr() parameters @start and @end are of type int. blkdebug_parse_filename(), blkverify_parse_filename(), nbd_parse_uri(), and qstring_from_str() pass @end values of type size_t or ptrdiff_t. Values exceeding INT_MAX get truncated, with possibly disastrous results. Such huge substrings seem unlikely, but we found one in a core dump, where "info tlb" executed via QMP's human-monitor-command apparently produced 35 GiB of output. Fix by changing the parameters size_t.

2018-07-03qmp: Don't let malformed in-band commands jump the queueMarkus Armbruster1-2/+0
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 cf869d53172 "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 cf869d53172. The next commit will fix queue jumping for syntax errors.

Commit cf869d53172 "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.

2018-06-15block: Add block-specific QDict headerMax Reitz1-17/+0
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.

2018-05-30qapi: introduce new cmd option "allow-preconfig"Igor Mammedov1-0/+1
New option will be used to allow commands, which are prepared/need to run, during preconfig state. Other commands that should be able to run in preconfig state, should be amended to not expect machine in initialized state or deal with it. For compatibility reasons, commands that don't use new flag 'allow-preconfig' explicitly are not permitted to run in preconfig state but allowed in all other states like they used to be. Within this patch allow following commands in preconfig state: qmp_capabilities query-qmp-schema query-commands query-command-line-options query-status exit-preconfig to allow qmp connection, basic introspection and moving to the next state. PS: set-numa-node and query-hotpluggable-cpus will be enabled later in a separate patches.

2018-05-04qobject: Replace qobject_incref/QINCREF qobject_decref/QDECREFMarc-André Lureau2-23/+19

The replacement is mechanical, except I broke a long line, and added a cast in monitor_qmp_cleanup_req_queue_locked(). Unlike qobject_decref(), qobject_unref() doesn't accept void *.

2018-05-04qobject: use a QObjectBase_ structMarc-André Lureau7-17/+26
By moving the base fields to a QObjectBase_, QObject can be a type which also has a 'base' field. This allows writing a generic QOBJECT() macro that will work with any QObject type, including QObject itself. The container_of() macro ensures that the object to cast has a QObjectBase_ base field, giving some type safety guarantees. QObject must have no members but QObjectBase_ base, or else QOBJECT() breaks. QObjectBase_ is not a typedef and uses a trailing underscore to make it obvious it is not for normal use and to avoid potential abuse.

2018-03-19qmp: support out-of-band (oob) executionPeter Xu1-0/+2
Having "allow-oob":true for a command does not mean that this command will always be run in out-of-band mode. The out-of-band quick path will only be executed if we specify the extra "run-oob" flag when sending the QMP request: { "execute": "command-that-allows-oob", "arguments": { ... }, "control": { "run-oob": true } } 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. 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.

2018-03-19qapi: introduce new cmd option "allow-oob"Peter Xu1-2/+3
Here "oob" stands for "Out-Of-Band". When "allow-oob" is set, it means the command allows out-of-band execution. The "oob" idea is proposed by Markus Armbruster in following thread: https://lists.gnu.org/archive/html/qemu-devel/2017-09/msg02057.html This new "allow-oob" boolean will be exposed by "query-qmp-schema" as well for command entries, so that QMP clients can know which commands can be used in out-of-band calls. For example the command "migrate" originally looks like: {"name": "migrate", "ret-type": "17", "meta-type": "command", "arg-type": "86"} And it'll be changed into: {"name": "migrate", "ret-type": "17", "allow-oob": false, "meta-type": "command", "arg-type": "86"} This patch only provides the QMP interface level changes. It does not contain the real out-of-band execution implementation yet.

2018-03-19qapi: Add qobject_to()Max Reitz1-0/+29
This is a dynamic casting macro that, given a QObject type, returns an object as that type or NULL if the object is of a different type (or NULL itself). The macro uses lower-case letters because: 1. There does not seem to be a hard rule on whether qemu macros have to be upper-cased, 2. The current situation in qapi/qmp is inconsistent (compare e.g. QINCREF() vs. qdict_put()), 3. qobject_to() will evaluate its @obj parameter only once, thus it is generally not important to the caller whether it is a macro or not, 4. I prefer it aesthetically. The macro parameter order is chosen with typename first for consistency with other QAPI macros like QAPI_CLONE(), as well as for legibility (read it as "qobject to" type "applied to" obj).

2017-09-04qapi: Change data type of the FOO_lookup generated for enum FOOMarc-André Lureau2-3/+8
Currently, a FOO_lookup is an array of strings terminated by a NULL sentinel. A future patch will generate enums with "holes". NULL-termination will cease to work then. To prepare for that, store the length in the FOO_lookup by wrapping it in a struct and adding a member for the length. The sentinel will be dropped next.

compare_litqobj_to_qobj() lacks a qlit_ prefix. Moreover, "compare" suggests -1, 0, +1 for less than, equal and greater than. The function actually returns non-zero for equal, zero for unequal. Rename to qlit_equal_qobject(). Its return type will be cleaned up in the next patch.

2017-09-04qlit: Change compound literals to initializersMarc-André Lureau1-4/+4
The QLIT_QFOO() macros expand into compound literals. Sadly, gcc doesn't recognizes these as constant expressions (clang does), which makes the macros useless for initializing objects with static storage duration. There is a gcc bug about it: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=71713 Change the macros to expand into initializers.
