This patch adds loading, stamp checking and initialization of modules.
The init function of dynamic module is no longer directly called as
__attribute__((constructor)) in static linked version, it is called
only after passed the checking of presense of stamp symbol:
qemu_stamp_$RELEASEHASH
where $RELEASEHASH is generated by hashing version strings and content
of configure script.
With this, modules built from a different tree/version/configure will
not be loaded.
The module loading code requires gmodule-2.0.
Modules are searched under
- CONFIG_MODDIR
- executable folder (to allow running qemu-{img,io} in the build
directory)
- ../ of executable folder (to allow running system emulator in the
build directory)
Modules are linked under their subdir respectively, then copied to top
level of build directory for above convinience, e.g.:
$(BUILD_DIR)/block/curl.so -> $(BUILD_DIR)/block-curl.so

* A new format is required to generate definitions for ust tracepoints.
Files ust_events_h.py and ust_events_c.py define common macros, while
new function ust_events_h in events.py does the actual definition of
each tracepoint.
* ust.py generates the new interface for calling userspace tracepoints
with LTTng 2.x, replacing trace_name(args) to tracepoint(name, args).
* As explained in ust_events_c.py, -Wredundant-decls gives a warning
when compiling with gcc 4.7 or older. This is specific to lttng-ust so
for now use a pragma clause to avoid getting a warning.

qmp-shell hides the QMP wire protocol JSON encoding from the user. Most
of the time this is helpful and makes the command-line human-friendly.
Some QMP commands take a dict as an argument. In order to express this
we need to revert back to JSON notation.
This patch allows JSON dict arguments in qmp-shell so commands like
blockdev-add and nbd-server-start can be invoked:
(QEMU) blockdev-add options={"driver":"file","id":"drive1",...}
Note that spaces are not allowed since str.split() is used to break up
the command-line arguments first.

The trace-events "disable" keyword turns an event into a nop at
compile-time. This is important for high-frequency events that can
impact performance.
The "disable" keyword is currently broken in the simple trace backend.
This patch fixes the problem as follows:
Trace events are identified by their TraceEventID number. When events
are disabled there are two options for assigning TraceEventID numbers:
1. Skip disabled events and don't assign them a number.
2. Assign numbers for all events regardless of the disabled keyword.
The simple trace backend and its binary file format uses approach #1.
The tracetool infrastructure has been using approach #2 for a while.
The result is that the numbers used in simple trace files do not
correspond with TraceEventIDs. In trace/simple.c we assumed that they
are identical and therefore emitted bogus numbers.
This patch fixes the bug by using TraceEventID for trace_event_id()
while sticking to approach #1 for simple trace file numbers. This
preserves simple trace file format compatibility.

When qemu dies unexpectedly, for example in response to an explicit
abort() call, or (more importantly) when an external signal is delivered
to it that results in a coredump, sometimes it is useful to extract the
guest vmcore from the qemu process' memory image. The guest vmcore might
help understand an emulation problem in qemu, or help debug the guest.
This script reimplements (and cuts many features of) the
qmp_dump_guest_memory() command in gdb/Python,
https://sourceware.org/gdb/current/onlinedocs/gdb/Python-API.html
working off the saved memory image of the qemu process. The docstring in
the patch (serving as gdb help text) describes the limitations relative to
the QMP command.
Dependencies of qmp_dump_guest_memory() have been reimplemented as needed.
I sought to follow the general structure, sticking to original function
names where possible. However, keeping it simple prevailed in some places.
The patch has been tested with a 4 VCPU, 768 MB, RHEL-6.4
(2.6.32-358.el6.x86_64) guest:

Detect presence of IASL compiler and use it
to process ASL source. If not there, use pre-compiled
files in-tree. Add script to update the in-tree files.
Note: distros are known to silently update iasl
so detect correct iasl flags for the installed version on each run as
opposed to at configure time.

outages due to DNS issues or IP address changes. For example, if the
web server IP address needs to change we cannot guarantee qemu.org will
point to it!
The newer qemu-project.org domain name is owned by Anthony Liguori
<anthony@codemonkey.ws>. You can confirm this by querying the whois
information. Also note that the #qemu IRC channel topic already
references qemu-project.org.
Short of having a dedicated legal entity to hold the domain name on
behalf of the community, qemu-project.org seems like the safest bet.
Let's replace references to qemu.org with qemu-project.org.
Note that git-submodule(1) does not detect URL changes. The following
commands clear out and re-initialize all submodules to ensure you are
using the latest URLs:
$ git submodule deinit . # you'll be warned if you have local changes
$ rm -rf .git/modules # also clear cached .git/ directories
$ git submodule update --init

This introduces a new 'base' key for struct definitions that refers to
another struct type. On the JSON level, the fields of the base type are
included directly into the same namespace as the fields of the defined
type, like with unions. On the C level, a pointer to a struct of the
base type is included.

Unlike other list types, enum wasn't adding any padding, which caused
a mismatch between the generated struct size and GenericList struct
size. More details in a678e26cbe89f7a27cbce794c2c2784571ee9d21
This crashed qemu if calling qmp query-tpm-types for example, which
upsets libvirt capabilities probing. Reproducer on i686:
(sleep 5; printf '{"execute":"qmp_capabilities"}\n{"execute":"query-tpm-types"}\n') | ./i386-softmmu/qemu-system-i386 -S -nodefaults -nographic -M none -qmp stdio

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.

The discriminator for anonymous unions is the data type. This allows to
have a union type that allows both of these:
{ 'file': 'my_existing_block_device_id' }
{ 'file': { 'filename': '/tmp/mydisk.qcow2', 'read-only': true } }
Unions like this are specified in the schema with an empty dict as
discriminator. For this example you could take:
{ 'union': 'BlockRef',
'discriminator': {},
'data': { 'definition': 'BlockOptions',
'reference': 'str' } }
{ 'type': 'ExampleObject',
'data: { 'file': 'BlockRef' } }

Instead of the rather verbose syntax that distinguishes base and

{ "type": "file",
"read-only": true,
"data": {
"filename": "test"
} }
...we can now have both in the same namespace, allowing a more direct
mapping of the command line, and moving fields between the common base
and subclasses without breaking the API:
{ "driver": "file",
"read-only": true,

The new 'base' key in a union definition refers to a struct type, which
is inlined into the union definition and can represent fields common to
all kinds.
For example the following schema definition...
{ 'type': 'BlockOptionsBase', 'data': { 'read-only': 'bool' } }
{ 'union': 'BlockOptions',
'base': 'BlockOptionsBase',
'data': {
'raw': 'BlockOptionsRaw'
'qcow2': 'BlockOptionsQcow2'
} }
...would result in this generated C struct:
struct BlockOptions
{
BlockOptionsKind kind;
union {
void *data;
BlockOptionsRaw * raw;
BlockOptionsQcow2 * qcow2;
};
bool read_only;
};

In qmp-marshal.c the dealloc visitor calls use the same errp
pointer of the input visitor calls. This means that if any of
the input visitor calls fails, then the dealloc visitor will
return early, before freeing the object's memory.
Here's an example, consider this code:
int qmp_marshal_input_block_passwd(Monitor *mon, const QDict *qdict, QObject **ret)
{
[...]
char * device = NULL;
char * password = NULL;
mi = qmp_input_visitor_new_strict(QOBJECT(args));
v = qmp_input_get_visitor(mi);
visit_type_str(v, &device, "device", errp);
visit_type_str(v, &password, "password", errp);
qmp_input_visitor_cleanup(mi);
if (error_is_set(errp)) {
goto out;
}
qmp_block_passwd(device, password, errp);
out:
md = qapi_dealloc_visitor_new();
v = qapi_dealloc_get_visitor(md);
visit_type_str(v, &device, "device", errp);
visit_type_str(v, &password, "password", errp);
qapi_dealloc_visitor_cleanup(md);
[...]
return 0;
}
Consider errp != NULL when the out label is reached, we're going
to leak device and password.
This patch fixes this by always passing errp=NULL for dealloc
visitors, meaning that we always try to free them regardless of
any previous failure. The above example would then be:
out:
md = qapi_dealloc_visitor_new();
v = qapi_dealloc_get_visitor(md);
visit_type_str(v, &device, "device", NULL);
visit_type_str(v, &password, "password", NULL);
qapi_dealloc_visitor_cleanup(md);

If 'data' for a command definition isn't a dict, but a string, it is
taken as a (struct) type name and the fields of this struct are directly
used as parameters.
This is useful for transactionable commands that can use the same type
definition for both the transaction action and the arguments of the
standalone command.
