We remove the CONFIG_LOCALTIME_R detection option in configure, and move the check
existence of gmtime_r from configure into C header and source directly by using macro
`_POSIX_THREAD_SAFE_FUNCTIONS`.
Before this patch, the configure script are always assume the compiler doesn't define
_POSIX_C_SOURCE macro at all, but that's not true, because thirdparty library such
as ncursesw may define -D_POSIX_C_SOURCE in it's pkg-config file. And that C Flags will
added -D_POSIX_C_SOURCE into each QEMU_CFLAGS. And that's causing the following compiling error:

Because most files in QEMU are grouped into static libraries, Meson conservatively
compiles them with -fPIC. This is overkill and produces slowdowns up to 20% on
some TCG tests.
As a stopgap measure, use the b_staticpic option to limit the slowdown to
--enable-pie. https://github.com/mesonbuild/meson/pull/7760 will allow
us to use b_staticpic=false and let Meson do the right thing.

Environment variables like CFLAGS are easy to accidentally change. Meson
warns if that happens, but in a project with a lot of configuration that
is easy to lose. It is also surprising behavior since meson caches -D
options and remembers those on reconfiguration (which we rely on,
since configure options become -D options).
By placing the user-provided CFLAGS, CXXFLAGS and LDFLAGS in the
cross file, we at least get consistent behavior. These environment
variables are still ugly and not really recommended, but there are
distros that rely on them. For the gory details, refer to
https://github.com/mesonbuild/meson/issues/4664.

If the CFLAGS, CXXFLAGS or LDFLAGS variables are present in the environment,
any modification made within the configure script is passed down to Meson.
This is particularly undesirable for the "-pie" option, since it overrides
"-shared" and thus messes up the linker flags for shared modules.
Using a separate variable therefore fixes the bug, while clarifying that
the scope of these CFLAGS is just the configure script.
We also do not need to pass those variables in config-host.mak; they
were only used for printing the summary now that all submodules are
built with handwritten Meson rules). For now synthesize CFLAGS in the
configuration summary, the next patch will also pass them in a cleaner
way using the cross file.

There are better ways to do this, e.g. meson cmake subproject,
but that requires cmake 3.7 and some of our CI environments
only provide cmake 3.5.
Nor can we add a meson.build file to capstone/, because the git
submodule would then always report "untracked files". Fixing that
would require creating our own branch on the qemu git mirror, at
which point we could just as easily create a native meson subproject.
Instead, build the library via the main meson.build.
This improves the current state of affairs in that we will re-link
the qemu executables against a changed libcapstone.a, which we wouldn't
do before-hand. In addition, the use of the configuration header file
instead of command-line -DEFINES means that we will rebuild the
capstone objects with changes to meson.build.

All Meson executables should specify their dependencies explicitly, either
directly or indirectly via declare_dependency. Makefiles instead did
not propagate dependencies correctly from static libraries, for example.
Therefore, flags for dependencies need not be included in QEMU_CFLAGS.
LIBS is not used at all, so drop that one as well.
In a few cases the dependencies were not yet specified, so add them.

The glib compilation flags were added to QEMU_CFLAGS. While we still
want them to be added to all compilation commands (at least for now),
do that via GLIB_CFLAGS rather than via QEMU_CFLAGS. This shows that
glib is a special case and makes it clearer that QEMU_CFLAGS is only
about compiler commands and not dependencies.

If nettle is disabled and gcrypt enabled, the compiler and linker flags
needed for gcrypt are not passed.
Gnutls was also not added as a dependancy when gcrypt is enabled.
Attempting to add the library dependencies at the same time as the
source dependencies is error prone, as there are alot of different
rules for picking which sources to use, and some of the source files
use code level conditionals intead. It is thus clearer to add the
library dependencies separately.

In case the qemu-keymap tool generating them is neither installed on the
system nor built from sources (due to xkbcommon not being available)
qemu will not find the keymaps when started directly from the build
tree,
This happens because commit ddcf607fa3 ("meson: drop keymaps symlink")
removed the symlink to the source tree, and the special handling for
install doesn't help in case we do not install qemu.
Lets fix that by simply copying over the file from the source tree as

When using --enable-werror for the macOS builders in the Cirrus-CI,
the atomic64 test is currently failing, and config.log shows a bunch
of error messages like this:
config-temp/qemu-conf.c:6:7: error: implicit declaration of function
'__atomic_load_8' is invalid in C99 [-Werror,-Wimplicit-function-declaration]
y = __atomic_load_8(&x, 0);
^
config-temp/qemu-conf.c:6:7: error: this function declaration is not a
prototype [-Werror,-Wstrict-prototypes]
Seems like these __atomic_*_8 functions are available in one of the
libraries there, so that the test links and passes there when not
using --enable-werror. But there does not seem to be a valid prototype
for them in any of the header files, so that the test fails when using
--enable-werror.
Fix it by using the "official" built-in functions instead (see e.g.
https://gcc.gnu.org/onlinedocs/gcc/_005f_005fatomic-Builtins.html).
We are not using the *_8 variants in QEMU anyway.

This patch implements functionality of following ioctls:
BTRFS_IOC_SUBVOL_CREATE - Creating a btrfs subvolume
Create a btrfs subvolume. The subvolume is created using the ioctl's
third argument which represents a pointer to a following structure
type:
struct btrfs_ioctl_vol_args {
__s64 fd;
char name[BTRFS_PATH_NAME_MAX + 1];
};
Before calling this ioctl, the fields of this structure should be filled
with aproppriate values. The fd field represents the file descriptor
value of the subvolume and the name field represents the subvolume
path.
BTRFS_IOC_SUBVOL_GETFLAGS - Getting subvolume flags
Read the flags of the btrfs subvolume. The flags are read using
the ioctl's third argument that is a pointer of __u64 (unsigned long).
The third argument represents a bit mask that can be composed of following
values:
BTRFS_SUBVOL_RDONLY (1ULL << 1)
BTRFS_SUBVOL_QGROUP_INHERIT (1ULL << 2)
BTRFS_DEVICE_SPEC_BY_ID (1ULL << 3)
BTRFS_SUBVOL_SPEC_BY_ID (1ULL << 4)
BTRFS_IOC_SUBVOL_SETFLAGS - Setting subvolume flags
Set the flags of the btrfs subvolume. The flags are set using the
ioctl's third argument that is a pointer of __u64 (unsigned long).
The third argument represents a bit mask that can be composed of same
values as in the case of previous ioctl (BTRFS_IOC_SUBVOL_GETFLAGS).
BTRFS_IOC_SUBVOL_GETINFO - Getting subvolume information
Read information about the subvolume. The subvolume information is
returned in the ioctl's third argument which represents a pointer to
a following structure type:
struct btrfs_ioctl_get_subvol_info_args {
/* Id of this subvolume */
__u64 treeid;
/* Name of this subvolume, used to get the real name at mount point */
char name[BTRFS_VOL_NAME_MAX + 1];
/*
* Id of the subvolume which contains this subvolume.
* Zero for top-level subvolume or a deleted subvolume.
*/
__u64 parent_id;
/*
* Inode number of the directory which contains this subvolume.
* Zero for top-level subvolume or a deleted subvolume
*/
__u64 dirid;
/* Latest transaction id of this subvolume */
__u64 generation;
/* Flags of this subvolume */
__u64 flags;
/* UUID of this subvolume */
__u8 uuid[BTRFS_UUID_SIZE];
/*
* UUID of the subvolume of which this subvolume is a snapshot.
* All zero for a non-snapshot subvolume.
*/
__u8 parent_uuid[BTRFS_UUID_SIZE];
/*
* UUID of the subvolume from which this subvolume was received.
* All zero for non-received subvolume.
*/
__u8 received_uuid[BTRFS_UUID_SIZE];
/* Transaction id indicating when change/create/send/receive happened */
__u64 ctransid;
__u64 otransid;
__u64 stransid;
__u64 rtransid;
/* Time corresponding to c/o/s/rtransid */
struct btrfs_ioctl_timespec ctime;
struct btrfs_ioctl_timespec otime;
struct btrfs_ioctl_timespec stime;
struct btrfs_ioctl_timespec rtime;
/* Must be zero */
__u64 reserved[8];
};
All of the fields of this structure are filled after the ioctl call.
Implementation notes:
Ioctls BTRFS_IOC_SUBVOL_CREATE and BTRFS_IOC_SUBVOL_GETINFO have structure
types as third arguments. That is the reason why a corresponding definition
are added in file 'linux-user/syscall_types.h'.
The line '#include <linux/btrfs.h>' is added in file 'linux-user/syscall.c' to
recognise preprocessor definitions for these ioctls. Since the file "linux/btrfs.h"
was added in the kernel version 3.9, it is enwrapped in an #ifdef statement
with parameter CONFIG_BTRFS which is defined in 'configure' if the
header file is present.

For architectures where the input file is not named syscall_nr.tbl,
syscall_nr.h has to be a source file; it's just a forwarder for x86

This shows how to do some "computations" in meson.build using its array

module for conditional compilation.
Notice the new "if have_system" part of util/meson.build, which fixes
a bug in the old build system was buggy: util/dbus.c was built even for
non-softmmu builds, but the dependency on -lgio was lost when the linking
was done through libqemuutil.a. Because all of its users required gio
otherwise, the bug was hidden. Meson instead propagates libqemuutil's
dependencies down to its users, and shows the problem.

Meson requires the build dir to be separate from the source tree. Many
people are used to just running "./configure && make" though and the
meson conversion breaks that.
This introduces some backcompat support to make it appear as if an
"in source tree" build is being done, but with the results in the
"build/" directory. This allows "./configure && make" to work as it
did historically, albeit with the output binaries staying under build/.

If pixman is not installed, it is currently not possible to run:
.../configure --disable-system --enable-tools
Seems like there was a dependency from one of the required source
files to pixman in the past, but since commit 1ac0206b2a
("qemu-timer.c: Trim list of included headers"), this dependency
should be gone. Thus allow to compile the tools without pixman now.

We already have a nice --enable-sanitizers option to enable
AddressSanitizer. There is no reason to duplicate and force this
functionality in --enable-fuzzing. In the future, if more sanitizers are
added to --enable-sanitizers, it might be impossible to build with both
--enable-sanitizers and --enable-fuzzing, since not all sanitizers are

Add a pair of configure options --{enable,disable}-libdaxctl to control
whether QEMU is compiled with libdaxctl [1]. Libdaxctl is a utility
library for managing the device dax subsystem.
QEMU uses mmap(2) to maps vNVDIMM backends and aligns the mapping
address to the page size (getpagesize(2)) by default. However, some
types of backends may require an alignment different than the page
size. The 'align' option is provided to memory-backend-file to allow
users to specify the proper alignment.
For device dax (e.g., /dev/dax0.0), the 'align' option needs to match
the alignment requirement of the device dax, which can be fetched
through the APIs of libdaxctl version 57 or up.
[1] Libdaxctl is a part of ndctl project.
The project's repository is: https://github.com/pmem/ndctl
For more information about libdaxctl APIs, you can refer to the
comments in source code of: pmem/ndctl/daxctl/lib/libdaxctl.c.

This patch adds a flag to enable/disable the SafeStack instrumentation
provided by LLVM.
On enable, make sure that the compiler supports the flags, and that we
are using the proper coroutine implementation (coroutine-ucontext).
On disable, explicitly disable the option if it was enabled by default.
While SafeStack is supported only on Linux, NetBSD, FreeBSD and macOS,
we are not checking for the O.S. since this is already done by LLVM.

On aarch64, gcc 9.3 is generating
qemu/exec.c: In function ‘address_space_translate_iommu’:
qemu/exec.c:431:28: note: parameter passing for argument of type \
‘MemTxAttrs’ {aka ‘struct MemTxAttrs’} changed in GCC 9.1
and many other repetitions. This structure, and the functions
amongst which it is passed, are not part of a QEMU public API.
Therefore we do not care how the compiler passes the argument,
so long as the compiler is self-consistent.
The only portion of QEMU which does have a public api, and so
must have a stable abi, is "qemu/plugin.h". We test this by
forcing -Wpsabi in tests/plugin/Makefile.

GDB's remote protocol requires M-profile cores to use the feature
name 'org.gnu.gdb.arm.m-profile' instead of the 'org.gnu.gdb.arm.core'
feature used for A- and R-profile cores. We weren't doing this, which
meant GDB treated our M-profile cores like A-profile ones. This mostly
doesn't matter, but for instance means that it doesn't correctly
handle backtraces where an M-profile exception frame is involved.
Ship a copy of GDB's arm-m-profile.xml and use it on the M-profile
cores. The integer registers have the same offsets as the
arm-core.xml, but register 25 is the M-profile XPSR rather than the
A-profile CPSR, so we need to update arm_cpu_gdb_read_register() and
arm_cpu_gdb_write_register() to handle XSPR reads and writes.

"Non-x86 are not changed, as they require TCG changes"

When re-run with "--accel tcg,thread=single" the instability goes

Which seems to indicate there is some aspect of the MIPS MTTCG fixes

have time to investigate and am not super familiar with the
architecture anyway. In lieu of someone tracking down the failure lets

glib's G_DEFINE_AUTOPTR_CLEANUP_FUNC() macro defines several static
inline functions, often with some of them unused, but prior to 2.57.2
did not mark the functions as such. As a result, clang (but not gcc)
fails to build with older glib unless -Wno-unused-function is enabled.

The comment in tcg-runtime-gvec.c about CONFIG_VECTOR16 says that
tcg-op-gvec.c has eliminated size 8 vectors, and only passes on
multiples of 16. This may have been true of the first few operations,
but is not true of all operations.
In particular, multiply, shift by scalar, and compare of 8- and 16-bit
elements are not expanded inline if host vector operations are not
supported.
For an x86_64 host that does not support AVX, this means that we will
fall back to the helper, which will attempt to use SSE instructions,
which will SEGV on an invalid 8-byte aligned memory operation.
This patch simply removes the CONFIG_VECTOR16 code and configuration
without further simplification.

glibc and Linux-provided headers are known to generate macro
redefinition warnings when used together. For example:
<linux/mman.h> and <sys/mman.h> duplicate some macro definitions.
We normally never see those warnings because GCC suppresses
warnings generated by system headers. We carry our own copy of
Linux header files, though, and this makes those warnings not be
suppressed when glibc headers are included before Linux headers
(e.g. if <sys/mman.h> is included before <linux/mman.h>).
Use -isystem instead of -I for linux-headers. This makes the
compiler treat our linux-headers directory the same way it treats
system-provided Linux headers, and suppress warnings generated by
them.

The Simple Authentication and Security Layer (SASL) library
re-defines the struct iovec on Win32 [*]. QEMU also re-defines
it in "qemu/osdep.h". The two definitions then clash on a MinGW
build.
We can avoid the SASL definition by defining STRUCT_IOVEC_DEFINED.
Since QEMU already defines 'struct iovec' if it is missing, add
the definition to vnc_sasl_cflags to avoid SASL re-defining it.

On upgrades the old .so files usually are replaced. But on the other
hand since a qemu process represents a guest instance it is usually kept
around.
That makes late addition of dynamic features e.g. 'hot-attach of a ceph
disk' fail by trying to load a new version of e.f. block-rbd.so into an
old still running qemu binary.
This adds a fallback to also load modules from a versioned directory in the
temporary /var/run path. That way qemu is providing a way for packaging
to store modules of an upgraded qemu package as needed until the next reboot.
An example how that can then be used in packaging can be seen in:

The recent Linux io_uring API has several advantages over ppoll(2) and
epoll(2). Details are given in the source code.
Add an io_uring implementation and make it the default on Linux.
Performance is the same as with epoll(7) but later patches add
optimizations that take advantage of io_uring.
It is necessary to change how aio_set_fd_handler() deals with deleting
AioHandlers since removing monitored file descriptors is asynchronous in
io_uring. fdmon_io_uring_remove() marks the AioHandler deleted and
aio_set_fd_handler() will let it handle deletion in that case.

This adds a new binary qemu-storage-daemon that doesn't yet do more than
some typical initialisation for tools and parsing the basic command
options --version, --help and --trace.
Even though this doesn't add any options yet that create things (like
--object or --blockdev), already document that we're planning to process
them in the order they are given on the command line rather than trying
(and failing, like vl.c) to resolve dependencies between options
automatically.

Currently configure's has_sphinx_build() check simply runs a dummy
sphinx-build and either passes or fails. This means that "no
sphinx-build at all" and "sphinx-build exists but is too old" are
both reported the same way.
Further, we want to assume that all the Python we write is running
with at least Python 3.5; configure checks that for our scripts, but
Sphinx extensions run with whatever Python version sphinx-build
itself is using.
Add a check to our conf.py which makes sphinx-build fail if it would
be running our extensions with an old Python, and handle this
in configure so we can report failure helpfully to the user.
This will mean that configure --enable-docs will fail like this
if the sphinx-build provided is not suitable:
Warning: sphinx-build exists but it is either too old or uses too old a Python version
ERROR: User requested feature docs
configure was not able to find it.
Install texinfo, Perl/perl-podlators and a Python 3 version of python-sphinx
(As usual, the default is to simply not build the docs, as we would
if sphinx-build wasn't present at all.)

Some of the CFLAGS that are discovered during configure, for example
compiler warnings, are being included on the linker command line because
QEMU_CFLAGS is added to it. Other flags, such as the -m32, appear twice
because they are included in both QEMU_CFLAGS and LDFLAGS. All this
leads to confusion with respect to what goes in which Makefile variables
(and we have plenty).
So, introduce QEMU_LDFLAGS for flags discovered by configure, following
the lead of QEMU_CFLAGS, and stop adding to it:
1) options that are already in CFLAGS, for example "-g"
2) duplicate options
At the same time, options that _are_ needed by both compiler and linker
must now be added to both QEMU_CFLAGS and QEMU_LDFLAGS, which is clearer.
This is mostly -fsanitize options. For now, --extra-cflags has this behavior
(but --extra-cxxflags does not).
Meson will not include CFLAGS on the linker command line, do the same in our
build system as well.

We only require libfdt for system emulation, in a small set
of architecture:
4077 # fdt support is mandatory for at least some target architectures,
4078 # so insist on it if we're building those system emulators.
4079 fdt_required=no
4080 for target in $target_list; do
4081 case $target in
4082 aarch64*-softmmu|arm*-softmmu|ppc*-softmmu|microblaze*-softmmu|mips64el-softmmu|riscv*-softmmu)
4083 fdt_required=yes
Do not build libfdt if we did not manually specified --enable-fdt,
or have one of the platforms that require it in our target list.
