Paolo Bonzini b5ed2e11ef build: disable Xen on ARM
While ARM could present the xenpv machine, it does not and trying to enable
it breaks compilation.  Revert to the previous test which only looked at
$target_name, not $cpu.

Peter Maydell e189091fba configure: Handle having no c++ compiler in FORTIFY_SOURCE check
Our FORTIFY_SOURCE check assumes that $cxx refers to a working C++
compiler, with the result that if you don't happen to have one
then configure will spuriously print
  configure: line 4685: c++: command not found

Fix this by adding a 'has $cxx' check.

Thomas Huth 5f37e6d4a7 configure: Fix build with pkg-config and --static --enable-sdl
The configure script prefers pkg-config over sdl-config, but
the "--static-libs" parameter only exists for the latter. With
pkg-config, "--static --libs" have to be used instead.

Paolo Bonzini b3f6ea7e55 configure: add --disable-tcg configure option
This lets you build without TCG (hardware accelerationor qtest only).  When
this flag is passed to configure, it will automatically filter out the target
list to only those that support KVM or Xen or HAX.

Peter Maydell b01a4fd3bd configure: Define NCURSES_WIDECHAR if we're using curses
We want the wide character functions from the ncurses header.
Unfortunately it doesn't provide them by default, but only
if either:
 * NCURSES_WIDECHAR is defined (for ncurses 20111030 and up)
 * _XOPEN_SOURCE/_XOPEN_SOURCE_EXTENDED are suitably defined

So far we have been implicitly relying on the latter, because
for GNU libc when we define _GNU_SOURCE this causes libc
to define the _XOPEN_SOURCE macros for us. Unfortunately
this doesn't work on all libcs, because some (like OSX and
musl libc) do not define _XOPEN_SOURCE when _GNU_SOURCE
is defined.

We can't fix this by defining _XOPEN_SOURCE ourselves, because
that also means "and don't provide any functions that aren't in
that standard", and not all libcs provide any way to override
that to also get the non-standard functions. In particular
FreeBSD has no such mechanism, and OSX's _DARWIN_C_SOURCE
doesn't reenable everything (for instance getpagesize()
is still not prototyped if _DARWIN_C_SOURCE and _XOPEN_SOURCE
are both defined).

So we have to define NCURSES_WIDECHAR. (This will only work
if your ncurses is at least 20111030, as older versions
don't honour this macro.)

Bruno Dominguez 11cde1c810 configure: split c and cxx extra flags
There was no possibility to add specific cxx flags using the configure
file. So A new entrance has been created to support it.

Duplication of information in configure and rules.mak. Taking
QEMU_CFLAGS and add them to QEMU_CXXFLAGS, now the value of
QEMU_CXXFLAGS is stored in config-host.mak, so there is no need for
it.

The makefile for libvixl was adding flags for QEMU_CXXFLAGS in
QEMU_CFLAGS because of the addition in rules.mak. That was removed, so
adding them where it should be.

Symlink .gdbinit and the scripts directory in order to make out-of-tree
builds work.  The scripts directory is used to find the qemu-gdb.py file
specified by a relative path in .gdbinit.

Kamil Rytarowski 271f37abb5 configure: Detect native NetBSD curses(3)
NetBSD ships with traditional BSD curses with compatibility with ncurses.
qemu works nicely with the basesystem version of curses(3) from NetBSD.

The only mismatch between curses(3) and ncurses is the lack of
curses_version() in the NetBSD version. This function is used solely in
the configure script, therefore eliminate it from the curses(3) detection.

With this change applied, configure detects correctly curses frontend.

switch-statement.

Both glfs_zerofill() and glfs_fallocate() have been introduced with
GlusterFS 3.5.0 (pkg-config glusterfs-api = 6). A #define for the
availability of glfs_fallocate() has been added to ./configure.

The GThread implementation is not functional enough to actually
run QEMU reliably. While it was potentially useful for debugging,
we have a scripts/qemugdb/coroutine.py to enable tracing of
ucontext coroutines in GDB, so that removes the only reason for
GThread to exist.

Andreas Grapentin 49e00a1870 use _Static_assert in QEMU_BUILD_BUG_ON
QEMU_BUILD_BUG_ON should use C11's _Static_assert, if the compiler supports it,
to provide more readable messages on failure.

We check for _Static_assert in configure, and set CONFIG_STATIC_ASSERT
accordingly. QEMU_BUILD_BUG_ON invokes _Static_assert if CONFIG_STATIC_ASSERT
is defined, and reverts to the old way otherwise.

That way, systems without C11 conforming compiler will still have the old
messages, as verified by intentionally breaking the configure check.

the following example output was generated by inverting the condition in
QEMU_BUILD_BUG_ON:

Juergen Gross c1cdd9d5be configure: use pkg-config for obtaining xen version
Instead of trying to guess the Xen version to use by compiling various
test programs first just ask the system via pkg-config. Only if it
can't return the version fall back to the test program scheme.

If configure is being called with dedicated flags for the Xen libraries
use those instead of the pkg-config output. This will avoid breaking
an in-tree Xen build of an old Xen version while a new Xen version is
installed on the build machine: pkg-config would pick up the installed
Xen config files as the Xen tree wouldn't contain any of them.

Peter Maydell ad04d8cb2f configure: on Windows minimum glib version must be 2.30
In the 2.7 release we stated in the ChangeLog that the
minimum glib version for Windows hosts was 2.30, but we
didn't update configure to enforce this because we were
very close to the release at the point where we noticed
the issue, and it only affected building the test suite.
We then forgot that we needed to do it. Fix the omission.

(The reason for the 2.30 requirement is use of
g_dir_make_tmp() -- our fallback implementation uses
mkdtemp(), which isn't available on Windows.)

Peter Maydell fb59dabd4f configure: Don't claim 'unsupported host OS' when better message available
The change in commit 898be3e041 which made completely
unrecognized OSes cause an error_exit "Unsupported host OS"
has some unfortunate unintended effects:
 * if you run 'configure --help' on an unsupported host OS
   (eg if intending to use it as a build machine for a
   cross compile to a supported host) then the message
   is printed instead of --help
 * if the C compiler doesn't work or is missing (eg if
   you passed an incorrect --cross-prefix by mistake)
   the message is printed instead of the more useful
   'compiler does not exist or does not work' message

Fix this by postponing the error_exit in this situation
until later, when we have already identified the more
useful cases for this.

The long term fix for this would be to move handling
of --help much further up in the configure script,
and make its output not dependent on checks that configure
runs. However for 2.9 this would be too invasive.

Peter Maydell 898be3e041 configure: Warn about deprecated hosts
We plan to drop support in a future QEMU release for host OSes
and host architectures for which we have no test machine where
we can build and run tests. For the 2.9 release, make configure
print a warning if it is run on such a host, so that the user
has some warning of the plans and can volunteer to help us
maintain the port if they need it to continue to function.

This commit flags up as deprecated the CPU architectures:
 * ia64
 * sparc
 * anything which we don't have a TCG port for
   (and which was presumably using TCI)
and the OSes:
 * GNU/kFreeBSD
 * DragonFly BSD
 * NetBSD
 * OpenBSD
 * Solaris
 * AIX
 * Haiku

It also makes entirely unrecognized host OS strings be
rejected rather than treated as if they were Linux (which
likely never worked).

sdl is probed before audio, so we can simply look at $sdl so see
whenever we have support or not.  Throw an error in case sdl audio
is requested without sdl being available.

Paolo Bonzini c8645752ce configure: remove Cygwin
The Cygwin target is really compiling for native Win32 with -mno-cygwin.
Except, GCC 4.7.0 has finally removed the long deprecated -mno-cygwin
option, and that happened about five years ago.

Let it rest in peace.

Christopher Covington 4d04351f4c build: include sys/sysmacros.h for major() and minor()
The definition of the major() and minor() macros are moving within glibc to
<sys/sysmacros.h>. Include this header when it is available to avoid the
following sorts of build-stopping messages:

qga/commands-posix.c: In function ‘dev_major_minor’:
qga/commands-posix.c:656:13: error: In the GNU C Library, "major" is defined

 currently defined by <sys/types.h> as well, but we plan to
 remove this soon. To use "major", include <sys/sysmacros.h>
 directly. If you did not intend to use a system-defined macro
 "major", you should undefine it after including <sys/types.h>. [-Werror]
         *devmajor = major(st.st_rdev);

Eric Blake e32ccbc6e9 block: Drop unmaintained 'archipelago' driver
The driver has failed to build since commit da34e65, in qemu 2.6,
due to a missing include of qapi/error.h for error_setg().
Since no one has complained in three releases, it is easier to
remove the dead code than to keep it around, especially since it
is not being built by default and therefore prone to bitrot.

Paul Burton df1d8a1f29 hw/mips: MIPS Boston board support
Introduce support for emulating the MIPS Boston development board. The
Boston board is built around an FPGA & 3 PCIe controllers, one of which
is connected to an Intel EG20T Platform Controller Hub. It is used
during the development & debug of new CPUs and the software intended to
run on them, and is essentially the successor to the older MIPS Malta
board.

This patch does not implement the EG20T, instead connecting an already
supported ICH-9 AHCI controller. Whilst this isn't accurate it's enough
for typical stock Boston software (eg. Linux kernels) to work with hard
disks given that both the ICH-9 & EG20T implement the AHCI
specification.

Boston boards typically boot kernels in the FIT image format, and this
patch will treat kernels provided to QEMU as such. When loading a kernel
directly, the board code will generate minimal firmware much as the
Malta board code does. This firmware will set up the CM, CPC & GIC
register base addresses then set argument registers & jump to the kernel
entry point. Alternatively, bootloader code may be loaded using the bios
argument in which case no firmware will be generated & execution will
proceed from the start of the boot code at the default MIPS boot
exception vector (offset 0x1fc00000 into (c)kseg1).

Currently real Boston boards are always used with FPGA bitfiles that
include a Global Interrupt Controller (GIC), so the interrupt
configuration is only defined for such cases. Therefore the board will
only allow use of CPUs which implement the CPS components, including the
GIC, and will otherwise exit with a message.

Alex Bennée ca759f9e38 tcg: enable MTTCG by default for ARM on x86 hosts
This enables the multi-threaded system emulation by default for ARMv7
and ARMv8 guests using the x86_64 TCG backend. This is because on the
guest side:

  - The ARM translate.c/translate-64.c have been converted to
    - use MTTCG safe atomic primitives
    - emit the appropriate barrier ops
  - The ARM machine has been updated to
    - hold the BQL when modifying shared cross-vCPU state
    - defer powerctl changes to async safe work

All the host backends support the barrier and atomic primitives but
need to provide same-or-better support for normal load/store
operations.

This reverts commit d3473e147a.

This commit creates a board which defaults to having 2GB of RAM.
Unfortunately on 32-bit hosts we can't create boards with 2GB of RAM,
and so 'make check' fails. I missed this during testing of the
merge, unfortunately. Luckily the offending commit is the last
one in the merge request, so we can just revert it for now.

Daniel P. Berrange ac7568bd3f rules: don't try to create missing include dirs
In

  commit ba78db44f6
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Wed Jan 25 16:14:10 2017 +0000

  make: move top level dir to end of include search path

The dir $(BUILD_DIR)/$(@D) was added to the include
path. This would sometimes point to a non-existant
directory, if the sub-dir in question did not contain
any target-independant files (eg tcg/). To deal with
this the rules.mak attempted to create the directory.

While this was succesful, it also caused accidental
creation of files in the parent of the build dir.
e.g. when building common source files into target
specific output files.

Rather than trying to workaround this, just revert
the code that attempted to mkdir the missing include
directories. Instead just turn off the compiler warning
in question as the missing dir is expected & harmless
in general.

NB: you can clean up a build directory parent that has
been filled with empty directories by commit ba78db44f6
using this GNU find command in that parent directory:
  find audio backends block chardev crypto disas fsdev hw io linux-user \
    migration nbd net qapi qom replay slirp target ui util \
    -type d -empty -delete

These files deal with the file protocol, not the raw format (the
file protocol is often used with other formats, and the raw
format is not forced to use the file protocol).  Rename things

Paolo Bonzini 7ecf44a579 rules.mak: Also try -r to build modules
Building qemu fails in distributions where gcc enables PIE by default
(e.g. Debian unstable) with:

/usr/bin/ld: -r and -pie may not be used together

You have to use -r instead of -Wl,-r to avoid gcc passing -pie to the linker
when PIE is enabled and a relocatable object is passed.  However, clang
does not know about -r, so try -Wl,-r first.

[This is a fix for commit c96f0ee6a6
("rules.mak: Use -r instead of -Wl, -r to fix building when PIE is
default") which mostly worked but broke the ./configure --enable-modules
build with clang.

/usr/include, but also with -I/usr/include/ncursesw.

To properly detect for wide support with and without -Werror, we need to

Stefan Hajnoczi 6a02c8069f sockets: add AF_VSOCK support
Add the AF_VSOCK address family so that qemu-ga will be able to use
virtio-vsock.

The AF_VSOCK address family uses <cid, port> address tuples.  The cid is
the unique identifier comparable to an IP address.  AF_VSOCK does not
use name resolution so it's easy to convert between struct sockaddr_vm
and strings.

This patch defines a VsockSocketAddress instead of trying to piggy-back
on InetSocketAddress.  This is cleaner in the long run since it avoids
lots of IPv4 vs IPv6 vs vsock special casing.

Eric Blake 6b39b06339 build: Work around SIZE_MAX bug in OSX headers
C99 requires SIZE_MAX to be declared with the same type as the
integral promotion of size_t, but OSX mistakenly defines it as
an 'unsigned long long' expression even though size_t is only
'unsigned long'.  Rather than futzing around with whether size_t
is 32- or 64-bits wide (which would be needed if we cared about
using SIZE_T in a #if expression), just hard-code it with a cast.
This is not a strict C99-compliant definition, because it doesn't
work in the preprocessor, but if we later need that, the build
will break on Mac to inform us to improve our replacement at that
time.

See also https://patchwork.ozlabs.org/patch/542327/ for an
instance where the wrong type trips us up if we don't fix it
for good in osdep.h.

Some versions of glibc make a similar mistake with SSIZE_MAX; the
goal is that the approach of this patch could be copied to work
around that problem if it ever becomes important to us.

Paulina Szubarczyk b6eb9b45f7 qdisk - hw/block/xen_disk: grant copy implementation
Copy data operated on during request from/to local buffers to/from
the grant references.

Before grant copy operation local buffers must be allocated what is
done by calling ioreq_init_copy_buffers. For the 'read' operation,
first, the qemu device invokes the read operation on local buffers
and on the completion grant copy is called and buffers are freed.
For the 'write' operation grant copy is performed before invoking
write by qemu device.

A new value 'feature_grant_copy' is added to recognize when the
grant copy operation is supported by a guest.

Peter Maydell 2d31515bc0 configure: Always compile with -fwrapv
QEMU's code relies on left shifts of signed integers always
being defined behaviour with the obvious 2s-complement
semantics. The only way to tell the compiler (and any
associated undefined-behaviour sanitizer) that we require a
C dialect with these semantics is to use the -fwrapv option.
This is a bit of a heavy hammer for the job as it also gives
us guaranteed semantics on integer arithmetic overflow which
in theory we don't require.

In an ideal world this would allow us to drop the warning
flag -Wno-shift-negative-value, but we must retain this to
avoid spurious warnings on clang versions predating the
fix to https://llvm.org/bugs/show_bug.cgi?id=25552.

Peter Maydell e57218b6ed pc-bios/optionrom: Fix OpenBSD build with better detection of linker emulation
The various host OSes are irritatingly variable about the name
of the linker emulation we need to pass to ld's -m option to
build the i386 option ROMs. Instead of doing this via a
CONFIG ifdef, check in configure whether any of the emulation
names we know about will work and pass the right answer through
to the makefile. If we can't find one, we fall back to not trying
to build the option ROMs, in the same way we would for a non-x86
host platform.

This is in particular necessary to unbreak the build on OpenBSD,
since it wants a different answer to FreeBSD and we don't have
an existing CONFIG_ variable that distinguishes the two.

Michael Roth 690604f696 configure: mark qemu-ga VSS includes as system headers
As of e4650c81, we do w32 builds with -Werror enabled. Unfortunately
for cases where we enable VSS support in qemu-ga, we still have
warnings generated by VSS includes that ship as part of the Microsoft
VSS SDK.

We can selectively address a number of these warnings using

  #pragma GCC diagnostic ignored ...

but at least one of these:

  warning: ‘typedef’ was ignored in this declaration

resulting from declarations of the form:

  typedef struct Blah { ... };

does not provide a specific command-line/pragma option to disable
warnings of the sort.

To allow VSS builds to succeed, the next-best option is disabling
these warnings on a per-file basis. pragmas like #pragma GCC
system_header can be used to declare subsequent includes/declarations
as being exempt from normal warnings, but this must be done within
a header file.

Since we don't control the VSS SDK, we'd need to rely on a
intermediate header include to accomplish this, and
since different objects in the VSS link target rely on different
headers from the VSS SDK, this would become somewhat of a rat's nest
(though not totally unmanageable).

The next step up in granularity is just marking the entire VSS
SDK include path as system headers via -isystem. This is a bit more
heavy-handed, but since this SDK hasn't changed since 2005, there's
likely little to be gained from selectively disabling warnings
anyway, so we implement that approach here.

This fixes the -Werror failures in both the configure test and the
qga build due to shared reliance on $vss_win32_include. For the
same reason, this also enforces a new dependency on -isystem support
in the C/C++ compiler when building QGA with VSS enabled.

Daniel P. Berrange 409437e16d tests: introduce a framework for testing migration performance
This introduces a moderately general purpose framework for
testing performance of migration.

The initial guest workload is provided by the included 'stress'
program, which is configured to spawn one thread per guest CPU
and run a maximally memory intensive workload. It will loop
over GB of memory, xor'ing each byte with data from a 4k array
of random bytes. This ensures heavy read and write load across
all of guest memory to stress the migration performance. While
running the 'stress' program will record how long it takes to
xor each GB of memory and print this data for later reporting.

The test engine will spawn a pair of QEMU processes, either on
the same host, or with the target on a remote host via ssh,
using the host kernel and a custom initrd built with 'stress'
as the /init binary. Kernel command line args are set to ensure
a fast kernel boot time (< 1 second) between launching QEMU and
the stress program starting execution.

None the less, the test engine will initially wait N seconds for
the guest workload to stablize, before starting the migration
operation. When migration is running, the engine will use pause,
post-copy, autoconverge, xbzrle compression and multithread
compression features, as well as downtime & bandwidth tuning
to encourage completion. If migration completes, the test engine
will wait N seconds again for the guest workooad to stablize on
the target host. If migration does not complete after a preset
number of iterations, it will be aborted.

While the QEMU process is running on the source host, the test
engine will sample the host CPU usage of QEMU as a whole, and
each vCPU thread. While migration is running, it will record
all the stats reported by 'query-migration'. Finally, it will
capture the output of the stress program running in the guest.

All the data produced from a single test execution is recorded
in a structured JSON file. A separate program is then able to
create interactive charts using the "plotly" python + javascript
libraries, showing the characteristics of the migration.

The data output provides visualization of the effect on guest
vCPU workloads from the migration process, the corresponding
vCPU utilization on the host, and the overall CPU hit from
QEMU on the host. This is correlated from statistics from the
migration process, such as downtime, vCPU throttling and iteration
number.

While the tests can be run individually with arbitrary parameters,
there is also a facility for producing batch reports for a number
of pre-defined scenarios / comparisons, in order to be able to
get standardized results across different hardware configurations
(eg TCP vs RDMA, or comparing different VCPU counts / memory
sizes, etc).

To use this, first you must build the initrd image

 $ make tests/migration/initrd-stress.img

To run a a one-shot test with all default parameters

 $ ./tests/migration/guestperf.py > result.json

This has many command line args for varying its behaviour.
For example, to increase the RAM size and CPU count and
bind it to specific host NUMA nodes

 $ ./tests/migration/guestperf.py \
       --mem 4 --cpus 2 \
       --src-mem-bind 0 --src-cpu-bind 0,1 \
       --dst-mem-bind 1 --dst-cpu-bind 2,3 \
       > result.json

Using mem + cpu binding is strongly recommended on NUMA
machines, otherwise the guest performance results will
vary wildly between runs of the test due to lucky/unlucky
NUMA placement, making sensible data analysis impossible.

To make it run across separate hosts:

 $ ./tests/migration/guestperf.py \
       --dst-host somehostname > result.json

To request that post-copy is enabled, with switchover
after 5 iterations

 $ ./tests/migration/guestperf.py \
       --post-copy --post-copy-iters 5 > result.json

Once a result.json file is created, a graph of the data
can be generated, showing guest workload performance per
thread and the migration iteration points:

 $ ./tests/migration/guestperf-plot.py --output result.html \
        --migration-iters --split-guest-cpu result.json

To further include host vCPU utilization and overall QEMU
utilization

 $ ./tests/migration/guestperf-plot.py --output result.html \
        --migration-iters --split-guest-cpu \
	--qemu-cpu --vcpu-cpu result.json

NB, the 'guestperf-plot.py' command requires that you have
the plotly python library installed. eg you must do

 $ pip install --user  plotly

Viewing the result.html file requires that you have the
plotly.min.js file in the same directory as the HTML
output. This js file is installed as part of the plotly
python library, so can be found in

  $HOME/.local/lib/python2.7/site-packages/plotly/offline/plotly.min.js

The guestperf-plot.py program can accept multiple json files
to plot, enabling results from different configurations to
be compared.

Finally, to run the entire standardized set of comparisons

  $ ./tests/migration/guestperf-batch.py \
       --dst-host somehost \
       --mem 4 --cpus 2 \
       --src-mem-bind 0 --src-cpu-bind 0,1 \
       --dst-mem-bind 1 --dst-cpu-bind 2,3
       --output tcp-somehost-4gb-2cpu

will store JSON files from all scenarios in the directory
named tcp-somehost-4gb-2cpu

We fail to pass to $(AS) all of the different flags that may be required

Daniel P. Berrange a1c5e949dd crypto: allow default TLS priority to be chosen at build time
Modern gnutls can use a global config file to control the
crypto priority settings for TLS connections. For example
the priority string "@SYSTEM" instructs gnutls to find the
priority setting named "SYSTEM" in the global config file.

Latest gnutls GIT codebase gained the ability to reference
multiple priority strings in the config file, with the first
one that is found to existing winning. This means it is now
possible to configure QEMU out of the box with a default
priority of "@QEMU,SYSTEM", which says to look for the
settings "QEMU" first, and if not found, use the "SYSTEM"
settings.

To make use of this facility, we introduce the ability to
set the QEMU default priority at build time via a new
configure argument.  It is anticipated that distro vendors
will set this when building QEMU to a suitable value for
use with distro crypto policy setup. eg current Fedora
would run

 ./configure --tls-priority=@SYSTEM

while future Fedora would run

 ./configure --tls-priority=@QEMU,SYSTEM

Daniel P. Berrange 0c16c056a4 crypto: switch hash code to use nettle/gcrypt directly
Currently the internal hash code is using the gnutls hash APIs.
GNUTLS in turn is wrapping either nettle or gcrypt. Not only
were the GNUTLS hash APIs not added until GNUTLS 2.9.10, but
they don't expose support for all the algorithms QEMU needs
to use with LUKS.

Address this by directly wrapping nettle/gcrypt in QEMU and
avoiding GNUTLS's extra layer of indirection. This gives us
support for hash functions on a much wider range of platforms
and opens up ability to support more hash functions. It also
avoids a GNUTLS bug which would not correctly handle hashing
of large data blocks if int != size_t.

Peter Maydell 7dd929dfdc configure: Make AVX2 test robust to non-ELF systems
The AVX2 optimization test assumes that the object format
is ELF and the system has the readelf utility. If this isn't
true then configure might fail or emit a warning (since in
a pipe "foo | bar >/dev/null 2>&1" does not redirect the
stderr of foo, only of bar). Adjust the check so that if
we don't have readelf or don't have an ELF object then we
just don't enable the AVX2 optimization.

Peter Maydell 92fe2ba8b0 configure: Improve usermode relocation linker option probe
The probe we do to determine what flags to use to make the usermode
executables use a non-default text address has some flaws:
 * we run it even if we're not building the user binaries
 * we don't expect "ld --verbose" to fail

The combination of these two results in a harmless but
ugly "ld: unknown option: --verbose" message when running
configure on OSX.

Improve the probe to only run when we need it and to fail
nicely when even the backstop 'ld --verbose' approach fails.

Peter Maydell affc88cc9b configure: Don't allow user-only targets for unknown CPU architectures
For the user-only targets, we need to know something about the host CPU
architecture even if we are using the TCI interpreter rather than TCG.
(In particular user-exec.c has code for handling signals that needs
to know about that host's context structures.)

Specifically forbid building the user-only targets on unknown CPU
architectures, rather than allowing them to configure but then fail
when building user-exec.c.

This change drops supports for two configurations which were theoretically
possible before:
 * linux-user targets on M68K hosts using TCI
 * linux-user targets on HPPA hosts using TCI

We don't think anybody is actually trying to use these in practice, though:
 * interpreted TCG on a slow host CPU would be unusably slow
 * the m68k user-exec.c support is missing is_write detection so guest
   code which writes to the same page it is executing from was broken
   (will include any guest program using signals)
 * HPPA TCG backend support was dropped two and a half years ago
   with no complaints

Peter Maydell 997f6ed3a1 configure: Don't override ARCH=unknown if enabling TCI
At the moment if configure finds an unknown CPU it will set
ARCH to 'unknown', and then later either bail out or set it
to 'tci' (depending on whether the user passed configure the
--enable-tcg-interpreter switch). This is unnecessarily
confusing, because we could be using TCI in two cases:
 * a known host architecture (in which case ARCH is set to
   the actual host architecture, like 'i386')
 * an unknown host architecture (in which case ARCH is
   set to 'tci')
so nothing can rely on ARCH=tci to mean "using TCI".
Remove the line setting ARCH, so we leave it as "unknown",
which is what the actual situation is.

Use the safe_syscall wrapper for epoll_wait and epoll_pwait syscalls.

Since we now directly use the host epoll_pwait syscall for both
epoll_wait and epoll_pwait, we don't need the configure machinery
to check whether glibc supports epoll_pwait(). (The kernel has
supported the syscall since 2.6.19 so we can assume it's always there.)

Peter Krempa e58ff62d58 audio: pa: Set volume of recording stream instead of recording device
Since pulseaudio 1.0 it's possible to set the individual stream volume
rather than setting the device volume. With this, setting hardware mixer
of a emulated sound card doesn't mess up the volume configuration of the
host.

A side effect is that this limits compatible pulseaudio version to 1.0
which was released on 2011-09-27.

Jeff Cody d85fa9eb87 block/gluster: prevent data loss after i/o error
Upon receiving an I/O error after an fsync, by default gluster will
dump its cache.  However, QEMU will retry the fsync, which is especially
useful when encountering errors such as ENOSPC when using the werror=stop
option.  When using caching with gluster, however, the last written data
will be lost upon encountering ENOSPC.  Using the write-behind-cache
xlator option of 'resync-failed-syncs-after-fsync' should cause gluster
to retain the cached data after a failed fsync, so that ENOSPC and other
transient errors are recoverable.

Unfortunately, we have no way of knowing if the
'resync-failed-syncs-after-fsync' xlator option is supported, so for now
close the fd and set the BDS driver to NULL upon fsync error.

Daniel P. Berrange 37788f253a crypto: add support for PBKDF2 algorithm
The LUKS data format includes use of PBKDF2 (Password-Based
Key Derivation Function). The Nettle library can provide
an implementation of this, but we don't want code directly
depending on a specific crypto library backend. Introduce
a new include/crypto/pbkdf.h header which defines a QEMU
API for invoking PBKDK2. The initial implementations are
backed by nettle & gcrypt, which are commonly available
with distros shipping GNUTLS.

The test suite data is taken from the cryptsetup codebase
under the LGPLv2.1+ license. This merely aims to verify
that whatever backend we provide for this function in QEMU
will comply with the spec.

The gcrypt impl is provided for cases where QEMU build

No nettle impl is provided, since it is non-trivial to

Ian Campbell edfb07ed22 xen: drop support for Xen 4.1 and older.
Xen 4.2 become unsupported upstream in 09/2015 (see
http://wiki.xen.org/wiki/Xen_Release_Features). However as far as the
interfaces provided by the toolstack libraries go 4.2 and 4.3 are
indistinguishable.

Therefore drop support for Xen 4.1 and earlier which removes a whole
pile of compatibility code which makes future work (to use stable
library interfaces provided by upstream) more difficult. In particular
all supported versions now use a pointer as a libxc handle (4.1 and
earlier used an integer, resulting in various shim layers).

Also Xen 4.2 was the first version of Xen to formally support upstream
QEMU (as a preview) so that makes sense as a cut-off now.

This change drops all the configure-y and resulting ifdefs in a mostly
mechanical way. A follow up will refactor wrappers which are now
unused.

Daniel P. Berrange 977a82ab56 configure: sanity check the glib library that pkg-config finds
Developers on 64-bit machines will often try to perform a
32-bit build of QEMU by running

  ./configure --extra-cflags="-m32"

Unfortunately if PKG_CONFIG_LIBDIR is not set to point to
the location of the 32-bit pkg-config files, then configure
will silently pick up the 64-bit pkg-config files and still
succeed.

This causes a problem for glib because it means QEMU will
be pulling in /usr/lib64/glib-2.0/include/glibconfig.h
instead of /usr/lib/glib-2.0/include/glibconfig.h

This causes problems because the 'gsize' type (defined as
'unsigned long') will no longer be fully compatible with
the 'size_t' type (defined as 'unsigned int'). Although
both are the same size, the compiler refuses to allow
casts from 'unsigned long *' to 'unsigned int *' as they
are different pointer types. This results in non-obvious
compiler errors when building QEMU eg

qga/commands-posix.c: In function ‘qmp_guest_set_user_password’:
qga/commands-posix.c:1912:55: error: passing argument 2 of ‘g_base64_decode’ from incompatible pointer type [-Werror=incompatible-pointer-types]
     rawpasswddata = (char *)g_base64_decode(password, &rawpasswdlen);
                                                            ^
In file included from /usr/include/glib-2.0/glib.h:35:0,
                 from qga/commands-posix.c:14:
/usr/include/glib-2.0/glib/gbase64.h:52:9: note: expected ‘gsize * {aka long unsigned int *}’ but argument is of type ‘size_t * {aka unsigned int *}’
 guchar *g_base64_decode         (const gchar  *text,
         ^
cc1: all warnings being treated as errors

To detect this problem, add a check to configure that
verifies that GLIB_SIZEOF_SIZE_T matches sizeof(size_t).
If this fails print a warning suggesting that the dev
probably needs to set PKG_CONFIG_LIBDIR.

On Fedora x86_64 it passes with any of:

 # ./configure
 # PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig ./configure --extra-cflags="-m32"
 # PKG_CONFIG_LIBDIR=/usr/lib64/pkgconfig ./configure --extra-cflags="-m64"

And fails with a mis-match

 # PKG_CONFIG_LIBDIR=/usr/lib64/pkgconfig ./configure --extra-cflags="-m32"
 # PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig ./configure --extra-cflags="-m64"

ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T.
       You probably need to set PKG_CONFIG_LIBDIR
       to point to the right pkg-config files for your
       build target

Ian Campbell 64a7ad6fe3 xen: make it possible to build without the Xen PV domain builder
Until the previous patch this relied on xc_fd(), which was only
implemented for Xen 4.0 and earlier.

Given this wasn't working since Xen 4.0 I have marked this as disabled
by default.

Removing this support drops the use of a bunch of symbols from
libxenctrl, specifically:

  - xc_domain_create
  - xc_domain_destroy
  - xc_domain_getinfo
  - xc_domain_max_vcpus
  - xc_domain_setmaxmem
  - xc_domain_unpause
  - xc_evtchn_alloc_unbound
  - xc_linux_build

This is another step towards only using Xen libraries which provide a
stable inteface.

Ian Campbell 5eeb39c24b xen: Use stable library interfaces when they are available.
In Xen 4.7 we are refactoring parts libxenctrl into a number of
separate libraries which will provide backward and forward API and ABI
compatiblity.

Specifically libxenevtchn, libxengnttab and libxenforeignmemory.

Previous patches have already laid the groundwork for using these by
switching the existing compatibility shims to reflect the intefaces to
these libraries.

So all which remains is to update configure to detect the libraries
and enable their use. Although they are notionally independent we take
an all or nothing approach to the three libraries since they were
added at the same time.

The only non-obvious bit is that we now open a proper xenforeignmemory
handle for xen_fmem instead of reusing the xen_xc handle.

Build tested with 4.0 .. 4.6 (inclusive) and the patches targetting
4.7 which adds these libraries.

This uses CONFIG_XEN_CTRL_INTERFACE_VERSION == 471 to cover the
introduction of these new interfaces.

though both bash and dash accept them. In any case this line
was causing odd output in the case where nettle is not present:
  nettle    no ()

(because if nettle is not present then $nettle will be "no",
not a null string or unset).

Rewrite it to just use an if.

Rodrigo Rebello fccd35a046 configure: use appropriate code fragment for -fstack-protector checks
The check for stack-protector support consisted in compiling and linking
the test program below (output by function write_c_skeleton()) with the
compiler flag -fstack-protector-strong first and then with
-fstack-protector-all if the first one failed to work:

  int main(void) { return 0; }

This caused false positives when using certain toolchains in which the
compiler accepted -fstack-protector-strong but no support was provided
by the C library, since for this stack-protector variant the compiler
emits canary code only for functions that meet specific conditions
(local arrays, memory references to local variables, etc.) and the code
fragment under test included none of them (hence no stack protection
code generated, no link failure).

This fix changes the test program used for -fstack-protector checks to
include a function that meets conditions which cause the compiler to
generate canary code in all variants.

Marc-André Lureau 421f4448ce tests: re-enable vhost-user-test
Commit 7fe34ca9c2 actually disabled vhost-user-test altogether,
since CONFIG_VHOST_NET is a per-target config variable.

tests/vhost-user-test is already x86/x64 softmmu specific test, in order
to enable it correctly, kvm & vhost-net are also conditions. To check
that, set CONFIG_VHOST_NET_TEST_$target when kvm is also enabled.

Since "check-qtest-x86_64-y = $(check-qtest-i386-y)", avoid duplication
when both x86 & x64 are enabled.

Other targets than x86 aren't enabled yet, and is intentionally left as
a future improvement, since I can't easily test those.

dann frazier ba060c53d5 seccomp: loosen library version dependency
Drop the libseccomp required version back to 2.1.0, restoring the ability
to build w/ --enable-seccomp on Ubuntu 14.04.

Commit 4cc47f8b3c tightened the dependency
on libseccomp from version 2.1.0 to 2.1.1. This broke building on Ubuntu
14.04, the current Ubuntu LTS release. The commit message didn't mention
any specific functional need for 2.1.1, just that it was the most recent
stable version at the time. I reviewed the changes between 2.1.0 and 2.1.1,
but it looks like that update just contained minor fixes and cleanups - no
obvious (to me) new interfaces or critical bug fixes.

This is a revert of ae6e8ef11e, but with a bit of refactoring,
and also specifically adding arm/aarch64, rather than all
architectures. Currently, libseccomp code appears to also support
mips, ppc, and s390. We could therefore allow qemu to enable
seccomp for those platforms as well, with additional configure
patches, given they're tested and proven to work.

John Snow b553a04280 configure: disable FORTIFY_SOURCE under clang
Some versions of clang may have difficulty compiling glibc headers when
-D_FORTIFY_SOURCE is used. For example, Clang++ 3.5.0-9.fc22 cannot
compile glibc's stdio headers when -D_FORTIFY_SOURCE=2 is used. This
manifests currently as build failures with clang and any arm target.

According to LLVM dev Richard Smith, clang does not target or support
FORTIFY_SOURCE + glibc, and it should not be relied on.
"It's still an unsupported combination, and while it might compile, some
of the checks are unlikely to work because they require a frontend
inliner to be useful"

See: http://lists.llvm.org/pipermail/cfe-dev/2015-November/045846.html

Conclusion: disable fortify-source if we appear to be using clang instead
of testing for compile success or failure, which may be incidental or not
indicative of proper support of the feature.

John Snow 5e4dfd3d4e configure: disallow ccache during compile tests
If the user is using ccache during the configuration step,
it may interfere with some of the configuration tests,
particularly the "Is ccache interfering with macro analysis" step,
which is a bit of a poetic problem.

1) Disallow ccache from reading from the cache during configure,
   but don't disable it entirely to allow us to see if it causes other
   problems.

2) Force off CCACHE_CPP2 during the ccache test to get a deterministic
   answer over whether or not we need to enable that feature later.

Daniel P. Berrange 9024603776 configure: avoid polluting global CFLAGS with tasn1 flags
The previous commit

  commit 9a2fd4347c
  Author: Daniel P. Berrange <berrange@redhat.com>
  Date:   Mon Apr 13 14:01:39 2015 +0100

    crypto: add sanity checking of TLS x509 credentials

defined new variables $TEST_LIBS and $TEST_CFLAGS and
used them in tests/Makefile to augment $LIBS and $CFLAGS.

Unfortunately this overlooks the fact that tests/Makefile
is not executed via recursive-make, it is just pulled into
the top level Makefile via an include statement. So rather
than just augmenting the compiler/linker flags for tests
it polluted the global flags.

This is thought to be behind a reported failure when
building the pixman module as a sub-module, since global
$CFLAGS are passed down to configure in pixman.

This change removes the $TEST_LIBS and $TEST_CFLAGS
replacing them with $TASN1_LIBS and $TASN1_CFLAGS,
setting only against specific objects/executables
that need them.

Daniel P. Berrange 91bfcdb01d crypto: allow use of nettle/gcrypt to be selected explicitly
Currently the choice of whether to use nettle or gcrypt is
made based on what gnutls is linked to. There are times
when it is desirable to be able to force build against a
specific library. For example, if testing changes to QEMU's
crypto code all 3 possible backends need to be checked
regardless of what the local gnutls uses.

It is also desirable to be able to enable nettle/gcrypt
for cipher/hash algorithms, without enabling gnutls
for TLS support.

This gives two new configure flags, which allow the
following possibilities

Automatically determine nettle vs gcrypt from what
gnutls links to (recommended to minimize number of
crypto libraries linked to)

 ./configure

Automatically determine nettle vs gcrypt based on
which is installed

 ./configure --disable-gnutls

Force use of nettle

 ./configure --enable-nettle

Force use of gcrypt

 ./configure --enable-gcrypt

Force use of built-in AES & crippled-DES

 ./configure --disable-nettle --disable-gcrypt

Michael Roth fafcaf1d74 build: qemu-ga: add 'qemu-ga' build target for w32
Currently POSIX builds rely on 'qemu-ga' target to do qga-only
distributable build. On w32, as with most standalone binary targets,
we rely on 'qemu-ga.exe' target.

Unlike with POSIX, qemu-ga for w32 has a number of related targets
such as VSS DLL and MSI package. We can do the full distributable
qga-only build on w32 with:

  make qemu-ga.exe

or:

  make msi

To make that work, we tie VSS dependencies onto qemu-ga.exe.
However, in reality the DLL isn't part of the binary, so we use a
filter to pull them out of the LINK recipe, which attempts to link
against prereqs for binary targets. Additionally, it could be argued
that VSS is a separate distributable, and shouldn't be implied by
qemu-ga.exe binary target.

To avoid this, we can tie the VSS dependencies only to the 'msi'
target, but that would make it impossible to do a qga-only build of
the w32 distributable without building the 'msi' package, which was
supported in the past.

An alternative approach is to add a new target to build the whole
distributable. w32 allows us to use the same build target we use
on POSIX, 'qemu-ga', since the current binary-only target on w32
is 'qemu-ga.exe'.

To further simplify the build, we also make 'qemu-ga' build the MSI
package if the appropriate ./configure options are set, making the
full qga-only build the same on both POSIX and w32: `make qemu-ga`

Daniel P. Berrange 4d9310f427 oslib-win32: only provide localtime_r/gmtime_r if missing
The oslib-win32 file currently provides a localtime_r and
gmtime_r replacement unconditionally. Some versions of
Mingw-w64 would provide crude macros for localtime_r/gmtime_r
which QEMU takes care to disable. Latest versions of Mingw-w64
now provide actual functions for localtime_r/gmtime_r, but
with a twist that you have to include unistd.h or pthread.h
before including time.h.  By luck some files in QEMU have
such an include order, resulting in compile errors:

  CC    util/osdep.o

This change adds a configure test to see if localtime_r
exits, and only enables the QEMU impl if missing. We also
re-arrange qemu-common.h try attempt to guarantee that all
source files get unistd.h before time.h and thus see the
localtime_r/gmtime_r defs.

Daniel P. Berrange 3e305e4a47 ui: convert VNC server to use QCryptoTLSSession
Switch VNC server over to using the QCryptoTLSSession object
for the TLS session. This removes the direct use of gnutls
from the VNC server code. It also removes most knowledge
about TLS certificate handling from the VNC server code.
This has the nice effect that all the CONFIG_VNC_TLS
conditionals go away and the user gets an actual error
message when requesting TLS instead of it being silently
ignored.

With this change, the existing configuration options for
enabling TLS with -vnc are deprecated.

Old syntax for anon-DH credentials:

  -vnc hostname:0,tls

New syntax:

  -object tls-creds-anon,id=tls0,endpoint=server \
  -vnc hostname:0,tls-creds=tls0

Old syntax for x509 credentials, no client certs:

  -vnc hostname:0,tls,x509=/path/to/certs

New syntax:

  -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=no \
  -vnc hostname:0,tls-creds=tls0

Old syntax for x509 credentials, requiring client certs:

  -vnc hostname:0,tls,x509verify=/path/to/certs

New syntax:

  -object tls-creds-x509,id=tls0,dir=/path/to/certs,endpoint=server,verify-peer=yes \
  -vnc hostname:0,tls-creds=tls0

This aligns VNC with the way TLS credentials are to be
configured in the future for chardev, nbd and migration
backends. It also has the benefit that the same TLS
credentials can be shared across multiple VNC server
instances, if desired.

If someone uses the deprecated syntax, it will internally
result in the creation of a 'tls-creds' object with an ID
based on the VNC server ID. This allows backwards compat
with the CLI syntax, while still deleting all the original
TLS code from the VNC server.

Daniel P. Berrange 9a2fd4347c crypto: add sanity checking of TLS x509 credentials
If the administrator incorrectly sets up their x509 certificates,
the errors seen at runtime during connection attempts are very
obscure and difficult to diagnose. This has been a particular
problem for people using openssl to generate their certificates
instead of the gnutls certtool, because the openssl tools don't
turn on the various x509 extensions that gnutls expects to be
present by default.

This change thus adds support in the TLS credentials object to
sanity check the certificates when QEMU first loads them. This
gives the administrator immediate feedback for the majority of
common configuration mistakes, reducing the pain involved in
setting up TLS. The code is derived from equivalent code that
has been part of libvirt's TLS support and has been seen to be
valuable in assisting admins.

It is possible to disable the sanity checking, however, via
the new 'sanity-check' property on the tls-creds object type,
with a value of 'no'.

Unit tests are included in this change to verify the correctness
of the sanity checking code in all the key scenarios it is
intended to cope with. As part of the test suite, the pkix_asn1_tab.c
from gnutls is imported. This file is intentionally copied from the
(long since obsolete) gnutls 1.6.3 source tree, since that version
was still under GPLv2+, rather than the GPLv3+ of gnutls >= 2.0.

Konrad Rzeszutek Wilk 20a544c7dc xen: use errno instead of rc for xc_domain_add_to_physmap
In Xen 4.6 commit cd2f100f0f61b3f333d52d1737dd73f02daee592
"libxc: Fix do_memory_op to return negative value on errors"
made the libxc API less odd-ball: On errors, return value is
-1 and error code is in errno. On success the return value
is either 0 or an positive value.

Since we could be running with an old toolstack in which the
Exx value is in rc or the newer, we add an wrapper around
the xc_domain_add_to_physmap (called xen_xc_domain_add_to_physmap)
which will always return the EXX.

Xen 4.6 did not change the libxc functions mentioned (same parameters)
so we piggyback on the fact that Xen 4.6 has a new function:
commit 504ed2053362381ac01b98db9313454488b7db40 "tools/libxc: Expose
new hypercall xc_reserved_device_memory_map" and check for that.

Jan Beulich d8b441a3fb xen/HVM: atomically access pointers in bufioreq handling
The number of slots per page being 511 (i.e. not a power of two) means
that the (32-bit) read and write indexes going beyond 2^32 will likely
disturb operation. The hypervisor side gets I/O req server creation
extended so we can indicate that we're using suitable atomic accesses
where needed, allowing it to atomically canonicalize both pointers when
both have gone through at least one cycle.

The Xen side counterpart (which is not a functional prereq to this
change, albeit a build one) went in already (commit b7007bc6f9).

Alexandre Derumier 7b01cb974f configure: Add support for jemalloc
This adds "--enable-jemalloc" and "--disable-jemalloc" to allow linking
to jemalloc memory allocator.

We have already tcmalloc support,
but it seem to not working well with a lot of iothreads/disks.

The main problem is that tcmalloc use a shared thread cache of 16MB
by default.
With more threads, this cache is shared, and some bad garbage collections
can occur if the cache is too low.

It's possible to tcmalloc cache increase it with a env var:
TCMALLOC_MAX_TOTAL_THREAD_CACHE_BYTES=256MB

With default 16MB, performances are  really bad with more than 2 disks.
Increasing to 256MB, it's helping but still have problem with 16 disks/iothreads.

Jemalloc don't have performance problem with default configuration.

Here the benchmark results in iops of 1 qemu vm randread 4K iodepth=32,
with rbd block backend (librbd is doing a lot of memory allocation),
1 iothread by disk

Michael Roth f33ca81f13 build: qemu-ga: fix VSS dependencies
Currently VSS dll/tlb files for use in w32 builds are only built as a
result of having been added to the general 'tools' target alongside
qemu-ga. This is fine for default make target, but if we build
qemu-ga directly via `make qemu-ga.exe`, the VSS files are not
created.

Fix this by moving the VSS dependencies to qemu-ga.exe directly.
With this move we can move the VSS files back out of 'tools',
and drop the extra handling from MSI target in Makefile.

Now we can build qemu-ga MSI package with:
  ./configure ...
  make qemu-ga.exe
  make msi

or simply:
  ./configure ...
  make msi

and no longer need to do a full build beforehand.

Michael Roth 1a34904e5b configure: qemu-ga: explicitly enable qemu-ga MSI support when probed
Currently, if we don't explicitly disable support for MSI installer
via --disable-guest-agent-msi, the configure variable that tracks
the flag, 'guest_agent_msi', never gets set unless one of the probes
fails. Subsequent code then treats this unset value the same as if it
were a "yes" value (via != "no" style checks).

Instead, set the default "yes" value explicitly after the probes, then
make subsequent code expect the values to be set.

This makes it easier to report on whether or not MSI support was
enabled via probe by looking at the ./configure summary.

cases where --enable-guest-agent/--disable-guest-agent have not been
passed to configure, qemu-ga support may end up getting enabled later,
as is the case with w32 builds. This leads to MSI probe prematurely
reporting error due to lack of qemu-ga support.

Fix this by moving MSI installer probe after the final qga probes.

Peter Maydell a30878e708 configure: Don't permit SDL or GTK on OSX
The cocoa GUI frontend assumes it is the only GUI (it redefines
main() so it always gets control before the rest of QEMU), so
it does not play well with other UIs like SDL or GTK. (Mostly
people building QEMU on OSX don't have the necessary dependencies
available for configure to build those other front ends, so
mostly this problem goes unnoticed.)

Make configure automatically disable the SDL and GTK front ends
if the cocoa front end is enabled. (We were sort of attempting
to do this for SDL before, but not in a way that worked very well.)

Michael Roth c54e1eb492 qga: added GuestPCIAddress information
PCIAddress inforfation is obtained via SetupApi, which provides the
information about address, bus, etc. We look throught entire device tree
in the system and try to find device object for given volume. For this PDO
SetupDiGetDeviceRegistryProperty is called, which reads PCI configuration
for a given devicei if it is possible.

This is the most convinient way for a userspace service. The lookup is
performed for every volume available. However, this information is
not mandatory for vss-provider.

In order to use SetupApi we need to notify linker about it. We do not need
to install additional libs, so we do not make separate configuration
option to use libsetupapi.su

SetupApi gives as the same information as kernel driver
with IRP_MN_QUERY_INTERFACE.

Daniel P. Berrange ddbb0d0966 crypto: introduce new module for computing hash digests
Introduce a new crypto/ directory that will (eventually) contain
all the cryptographic related code. This initially defines a
wrapper for initializing gnutls and for computing hashes with
gnutls. The former ensures that gnutls is guaranteed to be
initialized exactly once in QEMU regardless of CLI args. The
block quorum code currently fails to initialize gnutls so it
only works by luck, if VNC server TLS is not requested. The
hash APIs avoids the need to litter the rest of the code with
preprocessor checks and simplifies callers by allocating the
correct amount of memory for the requested hash.

Some recent patches require a function from libfdt version 1.4.0,
so we should check for this version during the configure step

we check for the availability of the required function
fdt_get_property_by_offset() instead instead.

gdb allows registers to be displayed/modified, and is being updated
to account for the new vector registers.  Mirror these changes in
the gdb stub in qemu so that this can be performed when gdb is
attached to the qemu gdbserver.

John Snow fd0e60530f configure: Add workaround for ccache and clang
Test if ccache is interfering with semantic analysis of macros,
disable its habit of trying to compile already pre-processed
versions of code if so. ccache attempts to save time by compiling
pre-processed versions of code, but this disturbs clang's static
analysis enough to produce false positives.

ccache allows us to disable this feature, opting instead to
compile the original version instead of its preprocessed version.
This makes ccache much slower for cache misses, but at least it
becomes usable with QEMU/clang.

This workaround only activates for users using ccache AND clang,
and only if their configuration is observed to be producing warnings.
You may need to clear your ccache for builds started without -Werror,
as those may continue to produce warnings from the cache.

Thanks to Peter Eisentraut for his writeup on the issue:

John Snow bbbf2e04e5 configure: silence glib unknown attribute __alloc_size__
The glib headers use GCC attributes.  Unfortunately the __GNUC__ and
__GNUC_MINOR__ version macros are also defined by clang, but clang
doesn't support the same attributes as GCC.

clang 3.5.0 does not support the __alloc_size__ attribute:

  c047507a9a

The following warning is produced:

  gstrfuncs.h:257:44: warning: unknown attribute '__alloc_size__' ignored [-Wunknown-attributes]
        G_GNUC_MALLOC G_GNUC_ALLOC_SIZE(2);
          gmacros.h:67:45: note: expanded from macro 'G_GNUC_ALLOC_SIZE'
                #define G_GNUC_ALLOC_SIZE(x) __attribute__((__alloc_size__(x)))

This patch checks whether glib headers cause warnings and disables
-Wunknown-attributes if it is able to.

Fam Zheng 2847b46958 configure: Add support for tcmalloc
This adds "--enable-tcmalloc" and "--disable-tcmalloc" to allow linking
to libtcmalloc from gperftools.

tcmalloc is a malloc implementation that works well with threads and is
fast, so it is good for performance.

It is disabled by default, because the MALLOC_PERTURB_ flag we use in
tests doesn't work with tcmalloc. However we can enable tcmalloc
specific heap checker and profilers later.

An IOPS gain can be observed with virtio-blk-dataplane, other parts of
QEMU will directly benefit from it as well:

disabling seccomp support in all other situations.

This reverts the two commits:

libxseg has changed license to GPLv3.  QEMU includes GPL "v2 only" code
which is not compatible with GPLv3.  This means the resulting binaries
may not be redistributable!

Disable Archipelago (libxseg) by default to prevent accidental license
violations.  Also warn if linking against libxseg is enabled to remind
the user.

Note that this commit does not constitute any advice about software
licensing.  If you have doubts you should consult a lawyer.

Libseccomp dependency was mandating version 2.2.0 on all architectures
and this was causing configure and virt-test to break on non-updates
distros. This patch works-around it and give a more flexible way to
check the version, giving more time for other distros to update
libseccomp version.
