2b9f74efcc configure: Move preadv check to meson.build
Move the preadv availability check to meson.build.  This is what we
want to be doing for host-OS-feature-checks anyway, but it also fixes
a problem with building for macOS with the most recent XCode SDK on a
Catalina host.

On that configuration, 'preadv()' is provided as a weak symbol, so
that programs can be built with optional support for it and make a
runtime availability check to see whether the preadv() they have is a
working one or one which they must not call because it will
runtime-assert.  QEMU's configure test passes (unless you're building
with --enable-werror) because the test program using preadv()
compiles, but then QEMU crashes at runtime when preadv() is called,
with errors like:

  dyld: lazy symbol binding failed: Symbol not found: _preadv
    Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
    Expected in: /usr/lib/libSystem.B.dylib

  dyld: Symbol not found: _preadv
    Referenced from: /Users/pm215/src/qemu/./build/x86/tests/test-replication
    Expected in: /usr/lib/libSystem.B.dylib

Meson's own function availability check has a special case for macOS
which adds '-Wl,-no_weak_imports' to the compiler flags, which forces
the test to require the real function, not the macOS-version-too-old
stub.

So this commit fixes the bug where macOS builds on Catalina currently
require --disable-werror.

15588a6245 configure: MinGW respect --bindir argument
There are two cases that need to be accounted for when compiling QEMU
for MinGW32:
 1) A standalone distribution, where QEMU is self contained and
    extracted by the user, such as a user would download from the QEMU
    website. In this case, all the QEMU executable files should be
    rooted in $prefix to ensure they can be easily found by the user
 2) QEMU integrated into a distribution image/sysroot/SDK and
    distributed with other programs. In this case, the provided
    arguments for bindir/datadir/etc. should be respected as they for a
    Linux build.

Restructures the MinGW path configuration so that all of the paths
except bindir use the same rules as when building for other platforms.
This satisfies #2 and #1 since these files do not need to be directly in
$prefix anyway.

The handling for --bindir is changed so that it defaults to $prefix on
MinGW (maintaining the compatibility with #1), but if the user specifies
a specific path when configuring it can also satisfy #2.

testing is only really stable as of 8.3.1 so lets gate our use of GDB

For direct testing you can just point to a locally compiled version of
gdb via configure, e.g.:

8e4e2b551d curl: remove compatibility code, require 7.29.0
cURL 7.16.0 was released in October 2006.  Just remove code that is
in all likelihood not being used anywhere, and require the oldest version

pkg-config is enough for QEMU, since it does not need extra information
such as the path for certicate authorities.  All supported platforms
today will all have pkg-config for curl, so we can drop curl-config.

9e62ba48ea configure,meson: support Control-Flow Integrity
This patch adds a flag to enable/disable control flow integrity checks
on indirect function calls.
This feature only allows indirect function calls at runtime to functions
with compatible signatures.

This feature is only provided by LLVM/Clang, and depends on link-time
optimization which is currently supported only with LLVM/Clang >= 6.0

We also add an option to enable a debugging version of cfi, with verbose
output in case of a CFI violation.

CFI on indirect function calls does not support calls to functions in
shared libraries (since they were not known at compile time), and such
calls are forbidden. QEMU relies on dlopen/dlsym when using modules,
so we make modules incompatible with CFI.

All the checks are performed in meson.build. configure is only used to
forward the flags to meson

c87ea11631 configure: add --without-default-features
By default QEMU enables a lot of features if it can probe and find the
support libraries. It also enables a bunch of features by default.
This patch adds the ability to build --without-default-features which
can be paired with a --without-default-devices for a barely functional
build.

The main use case for this is testing our build assumptions and for
minimising the amount of stuff you build if you just want to test a
particular feature on your relatively slow emulated test system. On
it's own I go from:

  $ ls -lh qemu-system-aarch64
  -rwxr-xr-x 1 alex alex 120M Dec 10 12:45 qemu-system-aarch64*
  $ ldd qemu-system-aarch64 | wc -l
  170

to:

  $ ls -lh qemu-aarch64
  -rwxr-xr-x 1 alex alex 43M Dec 10 12:41 qemu-aarch64*
  $ ldd qemu-system-aarch64 | wc -l
  57

which is still able to run my default Debian ARM64 machine with a lot
less fat involved.

0a2ebce92a configure: Compile with -Wimplicit-fallthrough=2
Coverity always complains about switch-case statements that fall through
the next one when there is no comment in between - which could indicate
a forgotten "break" statement. Instead of handling these issues after
they have been committed, it would be better to avoid them in the build
process already. Thus let's enable the -Wimplicit-fallthrough warning now.
The "=2" level seems to be a good compromise between being too strict and
too generic about the possible comments, so we'll start with "=2" for now.

bbd2d5a812 build: -no-pie is no functional linker flag
Recent binutils changes dropping unsupported options [1] caused a build
issue in regard to the optionroms.

  ld -m elf_i386 -T /<<PKGBUILDDIR>>/pc-bios/optionrom//flat.lds -no-pie \
    -s -o multiboot.img multiboot.o
  ld.bfd: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?)

This isn't really a regression in ld.bfd, filing the bug upstream
revealed that this never worked as a ld flag [2] - in fact it seems we
were by accident setting --nmagic).

Since it never had the wanted effect this usage of LDFLAGS_NOPIE, should be
droppable without any effect. This also is the only use-case of LDFLAGS_NOPIE
in .mak, therefore we can also remove it from being added there.

4b265c79a8 trace: use STAP_SDT_V2 to work around symbol visibility
QEMU binaries no longer launch successfully with recent SystemTap
releases. This is because modular QEMU builds link the sdt semaphores
into the main binary instead of into the shared objects where they are
used. The symbol visibility of semaphores is 'hidden' and the dynamic
linker prints an error during module loading:

  $ ./configure --enable-trace-backends=dtrace --enable-modules ...
  ...
  Failed to open module: /builddir/build/BUILD/qemu-4.2.0/s390x-softmmu/../block-curl.so: undefined symbol: qemu_curl_close_semaphore

The long-term solution is to generate per-module dtrace .o files and
link them into the module instead of the main binary.

In the short term we can define STAP_SDT_V2 so dtrace(1) produces a .o
file with 'default' symbol visibility instead of 'hidden'. This
workaround is small and easier to merge for QEMU 5.2 and downstream
backports.

13ceae6663 configure: Make "does libgio work" test pull in some actual functions
In commit 76346b6264 we tried to add a configure check that
the libgio pkg-config data was correct, which builds an executable
linked against it.  Unfortunately this doesn't catch the problem
(missing static library dependency info), because a "do nothing" test
source file doesn't have any symbol references that cause the linker
to pull in .o files from libgio.a, and so we don't see the "missing
symbols from libmount" error that a full QEMU link triggers.

(The ineffective test went unnoticed because of a typo that
effectively disabled libgio unconditionally, but after commit
3569a5dfc1 fixed that, a static link of the system emulator on
Ubuntu stopped working again.)

Improve the gio test by having the test source fragment reference a
g_dbus function (which is what is indirectly causing us to end up
wanting functions from libmount).

The Haiku VM that we are going to add is using _BSD_SOURCE instead
of BSD_SOURCE (without initial underscore)... according to David
Carlier, the BSD_SOURCE without underscore was likely a typo, so
let's simply add the underscore there now.
This fixes the build failure with the bswapXX() macros not being
defined after including <endian.h>.

d88618f717 configure: mark vhost-user Linux-only
The vhost-user protocol uses the Linux eventfd feature and is typically
connected to Linux kvm.ko ioeventfd and irqfd file descriptors. The
protocol specification in docs/interop/vhost-user.rst does not describe
how platforms without eventfd support work.

The QEMU vhost-user devices compile on other POSIX host operating
systems because eventfd usage is abstracted in QEMU. The libvhost-user
programs in contrib/ do not compile but we failed to notice since they
are not built by default.

Make it clear that vhost-user is only supported on Linux for the time
being. If someone wishes to support it on other platforms then the
details can be added to vhost-user.rst and CI jobs can test the feature
to prevent bitrot.

e5e856c1eb meson: move vhost_user_blk_server to meson.build
The --enable/disable-vhost-user-blk-server options were implemented in
./configure. There has been confusion about them and part of the problem
is that the shell syntax used for setting the default value is not easy
to read. Move the option over to meson where the conditions are easier
to understand:

  have_vhost_user_blk_server = (targetos == 'linux')

  if get_option('vhost_user_blk_server').enabled()
      if targetos != 'linux'
          error('vhost_user_blk_server requires linux')
      endif
  elif get_option('vhost_user_blk_server').disabled() or not have_system
      have_vhost_user_blk_server = false
  endif

This patch does not change behavior.

Make it possible to compile out the vhost-user-blk server. It is enabled
by default on Linux.

Note that vhost-user-server.c depends on libvhost-user, which requires
CONFIG_LINUX. The CONFIG_VHOST_USER dependency was erroneous since that
option controls vhost-user frontends (previously known as "master") and
not device backends (previously known as "slave").

Meson 0.56.0 correctly builds non-PIC static libraries with -fPIE if
b_pie=true.  We do not have to pass b_staticpic=true if PIE is requested
if Meson is new-enough, which improves performance.

76346b6264 configure: Test that gio libs from pkg-config work
On some hosts (eg Ubuntu Bionic) pkg-config returns a set of
libraries for gio-2.0 which don't actually work when compiling
statically. (Specifically, the returned library string includes
-lmount, but not -lblkid which -lmount depends upon, so linking
fails due to missing symbols.)

Check that the libraries work, and don't enable gio if they don't,
in the same way we do for gnutls.

cece116c93 configure: add option for virtiofsd
Currently it is unknown whether virtiofsd will be built at
configuration time. It will be automatically built when dependency
is met. Also, required libraries are not clear.

To make this clear, add configure option --{enable,disable}-virtiofsd.
The default is the same as current (enabled if available) like many
other options. When --enable-virtiofsd is given and dependency is not
met, we get:

  ERROR: Problem encountered: virtiofsd requires libcap-ng-devel and seccomp-devel
or
  ERROR: Problem encountered: virtiofsd needs tools and vhost-user support

In addition, configuration summary now includes virtiofsd entry:

5c53015a48 build: add --enable/--disable-libudev
Initially, libudev detection was bundled with --enable-mpath because
qemu-pr-helper was the only user of libudev.  Recently however the USB
U2F emulation has also started using libudev, so add a separate
option.  This also allows 1) disabling libudev if desired for static
builds and 2) for non-static builds, requiring libudev even if
multipath support is undesirable.

The multipath test is adjusted, because it is now possible to enter it
with configurations that should fail, such as --static --enable-mpath
--disable-libudev.

09e93326e4 build: replace ninjatool with ninja
Now that the build is done entirely by Meson, there is no need
to keep the Makefile conversion.  Instead, we can ask Ninja about
the targets it exposes and forward them.

The main advantages are, from smallest to largest:

- reducing the possible namespace pollution within the Makefile

- removal of a relatively large Python program

- faster build because parsing Makefile.ninja is slower than
parsing build.ninja; and faster build after Meson runs because
we do not have to generate Makefile.ninja.

- tracking of command lines, which provides more accurate rebuilds

In addition the change removes the requirement for GNU make 3.82, which
was annoying on Mac, and avoids bugs on Windows due to ninjatool not
knowing how to convert Windows escapes to POSIX escapes.

e1c4269763 block: deprecate the sheepdog block driver
This thread from a little over a year ago:

  http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html

states that sheepdog is no longer actively developed. The only mentioned
users are some companies who are said to have it for legacy reasons with
plans to replace it by Ceph. There is talk about cutting out existing
features to turn it into a simple demo of how to write a distributed
block service. There is no evidence of anyone working on that idea:

  https://github.com/sheepdog/sheepdog/commits/master

No real commits to git since Jan 2018, and before then just some minor
technical debt cleanup.

There is essentially no activity on the mailing list aside from
patches to QEMU that get CC'd due to our MAINTAINERS entry.

Fedora packages for sheepdog failed to build from upstream source
because of the more strict linker that no longer merges duplicate
global symbols. Fedora patches it to add the missing "extern"
annotations and presumably other distros do to, but upstream source
remains broken.

There is only basic compile testing, no functional testing of the
driver.

Since there are no build pre-requisites the sheepdog driver is currently
enabled unconditionally. This would result in configure issuing a
deprecation warning by default for all users. Thus the configure default
is changed to disable it, requiring users to pass --enable-sheepdog to
build the driver.

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:

After this patch, whenever ncursesw or other thirdparty libraries tried to define or not

assumption if _POSIX_C_SOURCE are defined. We solely relied on if the macro `_POSIX_THREAD_SAFE_FUNCTIONS`

The _POSIX_THREAD_SAFE_FUNCTIONS are defined in mingw header like this:

```

#define _POSIX_THREAD_SAFE_FUNCTIONS 200112L

0c3dd50eae configure: fix performance regression due to PIC objects
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.

cb8baa7720 configure: don't enable ASLR for --enable-debug Windows builds
Unlike other OSs it is not possible for gdb to temporarily disable ASLR when
debugging executables on Windows which causes gdb to fail with memory access
errors when trying to debug QEMU.

Keep ASLR enabled by default on Windows via the --dynamicbase compiler flag

functioning gdb is expected at the cost of slightly less security.

47b30835e4 configure: consistently pass CFLAGS/CXXFLAGS/LDFLAGS to meson
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.

5770e8afd6 configure: do not clobber environment CFLAGS/CXXFLAGS/LDFLAGS
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.

fbb4121d59 dtc: Convert Makefile bits to meson bits
Build the library via the main meson.build just like for capstone.
This improves the current state of affairs in that we will re-link
the qemu executables against a changed libfdt.a, which we wouldn't
do before-hand, and lets us remove the whole recursive make machinery.

4d34a86b2b slirp: Convert Makefile bits to meson bits
SLIRP uses Meson so it could become a subproject in the future,
but our choice of configure options is not yet supported in Meson
(https://github.com/mesonbuild/meson/pull/7740).

For now, build the library via the main meson.build just like for
capstone.

This improves the current state of affairs in that we will re-link
the qemu executables against a changed libslirp.a, which we wouldn't
do before-hand.

deb62371fe meson: move sparse detection to Meson and rewrite check_sparse.py
Pass the path to the program to scripts/check_sparse.py, which
previously was not included in config-host.mak.  Change
scripts/check_sparse.py to work with cgcc, which seems to
work better with sparse 0.6.x.
