It's not easy to figure out how monitor translates
strings: most QEMU code deals with translated indexes,
these are translated using _lookup arrays,
so you need to find the array name, and find the
appropriate offset.
This patch adds C99 indexes to lookup arrays, which makes it possible to
find the correct key using simple grep, and see that the matching is
correct at a glance.
Example:
Before:
const char *MigrationCapability_lookup[] = {
"xbzrle",
"rdma-pin-all",
"auto-converge",
"zero-blocks",
NULL,
};
After:
const char *MigrationCapability_lookup[] = {
[MIGRATION_CAPABILITY_XBZRLE] = "xbzrle",
[MIGRATION_CAPABILITY_RDMA_PIN_ALL] = "rdma-pin-all",
[MIGRATION_CAPABILITY_AUTO_CONVERGE] = "auto-converge",
[MIGRATION_CAPABILITY_ZERO_BLOCKS] = "zero-blocks",
[MIGRATION_CAPABILITY_MAX] = NULL,
};

Memory allocated with GLib needs to be freed with GLib. Freeing it
with free() instead of g_free() is a common error. Harmless when
g_free() is a trivial wrapper around free(), which is commonly the
case. But model the difference anyway.
In a local scan, this flags four ALLOC_FREE_MISMATCH. Requires
--enable ALLOC_FREE_MISMATCH, because the checker is still preview.

Without a model, Coverity can't know that the result of g_strdup()
needs to be fed to g_free().
One way to get such a model is to scan GLib, build a derived model
file with cov-collect-models, and use that when scanning QEMU.
Unfortunately, the Coverity Scan service we use doesn't support that.
Thus, we're stuck with the other way: write a user model. Doing that
for all of GLib is hardly practical. I'm doing it for the "String
Utility Functions" we actually use that return dynamically allocated
strings.
In a local scan, this flags 20 additional RESOURCE_LEAKs. The ones I
checked look genuine.
It also loses a NULL_RETURNS about ppce500_init() using
qemu_find_file() without error checking. I don't understand why.

In current versions of GLib, g_new() may expand into g_malloc_n().
When it does, Coverity can't see the memory allocation, because we
don't model g_malloc_n(). Similarly for g_new0(), g_renew(),
g_try_new(), g_try_new0(), g_try_renew().
Model g_malloc_n(), g_malloc0_n(), g_realloc_n(). Model
g_try_malloc_n(), g_try_malloc0_n(), g_try_realloc_n() by adding
indeterminate out of memory conditions on top.
To avoid undue duplication, replace the existing models for g_malloc()
& friends by trivial wrappers around g_malloc_n() & friends.
In a local scan, this flags four additional RESOURCE_LEAKs and one
NULL_RETURNS.
The NULL_RETURNS is a false positive: Coverity can now see that
g_try_malloc(l1_sz * sizeof(uint64_t)) in
qcow2_check_metadata_overlap() may return NULL, but is too stupid to
recognize that a loop executing l1_sz times won't be entered then.
Three out of the four RESOURCE_LEAKs appear genuine. The false
positive is in ppce500_prep_device_tree(): the pointer dies, but a
pointer to a struct member escapes, and we get the pointer back for
freeing with container_of(). Too funky for Coverity.

While running kvm_stat using tracepoint on ARM64 hardware (e.g. "kvm_stat
-1 -t"), the initial values of some kvm_userspace_exit counters were found
to be very suspecious. For instance the tracing tool showed that S390_TSCH
was called many times on ARM64 machine, which apparently was wrong.
This patch adds RESET ioctl support for perf monitoring. Before calling
ioctl to enable a perf event, this patch resets the counter first. With
this patch, the init counter values become correct on ARM64 hardware.
Example:
==== before patch ====
kvm_userspace_exit(S390_SIEIC) 1426 0
kvm_userspace_exit(S390_TSCH) 339 0
==== after patch ====
kvm_userspace_exit(S390_SIEIC) 0 0

call fails, the returned value is -1, which doesn't tell the details

Make sure that all generated C structs have at least one field; this
avoids potential issues with attempting to malloc space for
zero-length structs in C (g_malloc(sizeof struct) would return NULL).
It also avoids an incompatibility with C++ (where an empty struct is
size 1); that isn't important to us now but might be in future.
Generated empty structures look like this:
struct Abort
{
char qapi_dummy_field_for_empty_struct;
};
This silences clang warnings like:
./qapi-types.h:3752:1: warning: empty struct has size 0 in C, size 1 in C++ [-Wextern-c-compat]

CODING_STYLE states the following about braces around blocks:
> The opening brace is on the line that contains the control flow
> statement that introduces the new block; [...]
This is obviously impossible with multi-line conditions. Therefore,
CODING_STYLE does not make any clear statement about where to put the
opening brace after a multi-line condition.
There is a reason to prefer to place the opening brace on an own line
after such a condition while still placing it on the same line as the
"control flow statement" if possible; that reason is that the last line
of a multi-line condition is indented, in the case of "if", it is often
indented by four spaces, just as much as the first statement in the
block will be indented. This is hard to read as there is no clearly
visible distinction between condition and block. Placing the opening
brace on a separate line solves this issue.
Also, there are cases where placing the opening brace on a separate line
is the only viable option; if the previous line had nearly 80 characters
and splitting it is not desirable, the opening brace is naturally placed
on an own line.
This patch fixes checkpatch.pl to not complain about braces on own lines
if the condition introducing the block spanned more than one line, or if
the previous line had 79 or 80 characters.
Furthermore, the warning about not having braces around a block is fixed
to mind braces not being on the last line of the condition.

In some cases an input visitor might bail out on filling out a
struct for various reasons, such as missing fields when running
in strict mode. In the case of a QAPI Union type, this may lead
to cases where the .kind field which encodes the union type
is uninitialized. Subsequently, other visitors, such as the
dealloc visitor, may use this .kind value as if it were
initialized, leading to assumptions about the union type which
in this case may lead to segfaults. For example, freeing an
integer value.
However, we can generally rely on the fact that the always-present
.data void * field that we generate for these union types will
always be NULL in cases where .kind is uninitialized (at least,
there shouldn't be a reason where we'd do this purposefully).
So pass this information on to Visitor implementation via these
optional start_union/end_union interfaces so this information
can be used to guard against the situation above. We will make
use of this information in a subsequent patch for the dealloc
visitor.

Red Hat Enterprise Linux 5 ships Python 2.4.3. The all() function was
added in Python 2.5 so we cannot use it.

There is one instance of any() in qapi.py that breaks builds on older
distros that ship Python 2.4 (like RHEL5):

Most QEMU typedefs are camelcase, starting with one uppercase letter
and containing at least one lowercase letter. There are a few
all-uppercase types, add the most common too.
This fixes recognition of types in lines such as
static __attribute__((unused)) inline void tcg_out8(TCGContext *s, uint8_t v)
(Example provided by Peter Maydell).

This makes the UST backend pay attention to the format string arguments
that are defined when defining payload data. With this you can now
ensure integers are reported in hex mode if you want.

Generate header "trace/generated-tcg-tracers.h" with the necessary routines for
tracing events in guest code:
* trace_${event}_tcg
Convenience wrapper that calls the translation-time tracer
'trace_${event}_trans', and calls 'gen_helper_trace_${event}_exec to
generate the TCG code to later trace the event at execution time.

Generates header "trace/generated-helpers-wrappers.h" with definitions for TCG
helper wrappers.
These wrappers ('gen_helper_trace_${event}_exec_wrapper') transform mixed native
and TCG argument types to TCG types and call the actual TCG helpers
('gen_helper_trace_${event}_exec_proxy').

Generates file "trace/generated-helpers.c" with TCG helper definitions to trace
events in guest code at execution time.
The helpers ('helper_trace_${event}_exec_proxy') cast the TCG-compatible native
argument types to their original types (as defined in "trace-events") and call
the tracing routine ('trace_${event}_exec').
