We threatened to remove ia64 as host in v2.9.0. Its time has now come.
There are still some usages of defined(__ia64__) throughout the source
code that would be triggered if one were to enable TCI on an ia64 host.

KVM guests on s390 need a different page table layout than normal
processes (2kb page table + 2kb page status extensions vs 2kb page table
only). As of today this has to be enabled via the vm.allocate_pgste
sysctl.
Newer kernels (>= 4.12) on s390 check for an S390_PGSTE program header
and enable the pgste page table extensions in that case. This makes the
vm.allocate_pgste sysctl unnecessary. We enable this program header for
the s390 system emulation (qemu-system-s390x) if we build on s390
- for s390 system emulation
- the linker supports --s390-pgste (binutils >= 2.29)
- KVM is enabled
This will allow distributions to disable the global vm.allocate_pgste
sysctl, which will improve the page table allocation for non KVM
processes as only 2kb chunks are necessary.

Learn to compile out vhost-user (net, scsi & upcoming users). Keep it

When trying to make a vhost-user netdev, it gives the following error:

Clang 3.9 passes the CONFIG_AVX2_OPT configure test. However, the
supplied <cpuid.h> does not contain the bit_AVX2 define that we use
when detecting whether the routine can be enabled.
Introduce a qemu-specific header that uses the compiler's definition
of __cpuid et al, but supplies any missing bit_* definitions needed.
This avoids introducing any extra ifdefs to util/bufferiszero.c, and
allows quite a few to be removed from tcg/i386/tcg-target.inc.c.

Solaris 9 was released in 2002, its successor Solaris 10 was

Nobody has stepped forward to express interest in supporting

For a very long time we have used 'uname -s' as our fallback if
we don't identify the target OS using a compiler #define. This
obviously doesn't work for cross-compilation, and we've had
a comment suggesting we fix this in configure for a long time.
Since we now have an exhaustive list of which OSes we can run
on (thanks to commit 898be3e041 making an unrecognized OS
be a fatal error), we know which ones we're missing.
Add check_define tests for the remaining OSes we support. The
defines checked are based on ones we already use in the codebase for
identifying the host OS (with the exception of GNU/kFreeBSD).
We can now set bogus_os immediately rather than doing it later.
We leave the comment about uname being bad untouched, since
there is still a use of it for the fallback for unrecognized
host CPU type.

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.)

seem to work. 'min-glib' jammed while gtesting moxie, which seems
very unlikely to be caused by this series. 'ubuntu', 'debian' and
'debian-bootstrap' hit build errors almost immediately that look like
problems with the container configuration, and 'debian-*-cross' hit
build errors later on which also look like missing dependencies from
the container.

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.

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:

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.

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.)

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.

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

hw/mips: MIPS Boston board support
Signed-off-by: Peter Maydell <peter.maydell@linaro.org>
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.

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 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.

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:

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

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

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.

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.

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

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.

Implement the new virtio sockets device for host<->guest communication
using the Sockets API. Most of the work is done in a vhost kernel
driver so that virtio-vsock can hook into the AF_VSOCK address family.
The QEMU vhost-vsock device handles configuration and live migration
while the rx/tx happens in the vhost_vsock.ko Linux kernel driver.
The vsock device must be given a CID (host-wide unique address):
# qemu -device vhost-vsock-pci,id=vhost-vsock-pci0,guest-cid=3 ...

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

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.

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

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

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.

is ELF and the system has the readelf utility. If this isn't
true then configure might fail or emit a warning (since in

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

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

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.)

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.

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.

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]

cc1: all warnings being treated as errors
To detect this problem, add a check to configure that

If this fails print a warning suggesting that the dev

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"

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

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

Removing this support drops the use of a bunch of symbols from

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.

The implementation is able to manage a single socket file
descriptor, whether a TCP/UNIX listener, TCP/UNIX connection,

is no asynchronous DNS lookup API available, it uses the

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.

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.

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.

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.

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.

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

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`

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:

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.

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.

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.

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).

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),

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.

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.

MSI probe assumes that qemu-ga support has been probed already, but in
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.

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.)

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.

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.

so we should check for this version during the configure step
already. Unfortunately, there does not seem to be a proper #define
for the version number in the libfdt headers. So alternatively,
we check for the availability of the required function
fdt_get_property_by_offset() instead instead.

It makes sense that extra-cflags should be appended after the normal
CFLAGS so they don't get overridden by default behaviour. This way if
you specify something like:
./configure --extra-cflags="-O0"
You will see the requested behaviour.

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.

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:

This patch adds support for bzip2-compressed block entries as introduced
with OS X 10.4 (source: https://en.wikipedia.org/wiki/Apple_Disk_Image).
It was tested against a 5.2G "OS X Yosemite" installation image which
stores the BLXX block in the XML property list (instead of resource
forks) and has over 5k chunks.
New configure entries are added (--enable-bzip2 / --disable-bzip2) to
control inclusion of bzip2 functionality (which requires linking against
libbz2). The help message suggests that this option is needed for DMG
files, but the tests are generic enough that other parts of QEMU can use
bzip2 if needed.
The identifiers are based on http://newosxbook.com/DMG.html.
The decompression routines are based on the zlib case, but as there is
no way to reset the decompression state (unlike zlib), memory is
allocated and deallocated for every decompression. This should not be
problematic as the decompression takes most of the time and as blocks
are typically about/over 1 MiB in size, only one allocation is done
every 2000 sectors.

The ioreq-server API added to Xen 4.5 offers better security than
the existing Xen/QEMU interface because the shared pages that are
used to pass emulation request/results back and forth are removed
from the guest's memory space before any requests are serviced.
This prevents the guest from mapping these pages (they are in a
well known location) and attempting to attack QEMU by synthesizing
its own request structures. Hence, this patch modifies configure
to detect whether the API is available, and adds the necessary
code to use the API if it is.

This function was only added in glib 2.38, and our
minimum version is 2.12.
To fix, disable the test for glib < 2.38.

commit a93a3af9 introduces use of PIXMAN_TYPE_RGBA, but it's only available
in pixman >= 0.21.8. If pixman doesn't meet the version requirement, qemu
will fail to build with following message:

VM Image on Archipelago volume is specified like this:
file.driver=archipelago,file.volume=<volumename>[,file.mport=<mapperd_port>[,
file.vport=<vlmcd_port>][,file.segment=<segment_name>]]
'archipelago' is the protocol.
'mport' is the port number on which mapperd is listening. This is optional
and if not specified, QEMU will make Archipelago to use the default port.
'vport' is the port number on which vlmcd is listening. This is optional
and if not specified, QEMU will make Archipelago to use the default port.
'segment' is the name of the shared memory segment Archipelago stack is using.
This is optional and if not specified, QEMU will make Archipelago to use the

Some non-linux systems, for example a system with
FreeBSD kernel and glibc, may declare struct mmsghdr
(in glibc) but may not have linux-specific header
file linux/ip.h. The actual implementation in qemu
includes this linux-specific header file unconditionally,
so compilation fails if it is not present. Include

The existing test whether "-lm" needs to be included or not is
insufficient as it reports false negative on Fedora20/ppc64.
This happens because sin(0.0) is a constant value which compiler
can safely throw away and therefore there is no need to add "-lm".
As the result, qemu-nbd/qemu-io/qemu-img tools cannot compile.
This adds a global variable and uses it in the test to prevent
from optimization.

a socket backend, with a set path (i.e. a Unix socket) and optionally
the server parameter set, will be allowed. Other options (nowait, telnet)
will make the chardev unusable and the netdev will not be initialised.
Additional checks for validity:
- requires `-numa node,memdev=..`
- requires `-device virtio-net-*`
The `vhostforce` option is used to force vhost-net when we deal with

This patch lifts the minimum supported libiscsi version from 1.4.0 to
1.9.0 since the BUSY patch required that change.
On one this allows us to remove all #ifdefs from the code which
makes the code easier to maintain and read. On the other hand
I would not recommend libiscsi prior to 1.8.0 for production use
because the following important libiscsi fixes for deadlocks and
protocol errors are missing prior to 1.8.0:
dbe9a1e SOCKET queue cmd PDUs directly in waitpdu queue
30df192 DATA-OUT set pdu->cmdsn appropriately
548bd22 ISCSI fix broken send logic in iscsi_scsi_async_command
14bee10 RECONNECT do not increase CmdSN for immediate PDUs
1f4a66a PDU queue out PDUs in order of itt.
562dd46 PDU avoid incrementing itt to 0xffffffff
cd09c0f PDU use serial32 arithmetic for cmdsn, maxcmdsn and expcmdsn.
89e918e SOCKET validate data_size in in_pdu header
91267f5 Limit immediate and unsolicited data to FirstBurstLength

Adds support to compile QEMU with multiple tracing backends at the same time.
For example, you can compile QEMU with:
$ ./configure --enable-trace-backends=ftrace,dtrace
Where 'ftrace' can be handy for having an in-flight record of events, and 'dtrace' can be later used to extract more information from the system.
This patch allows having both available without recompiling QEMU.

When libtool support was added to configure, the new temporary files
were left out of the list of files cleaned up on exit; this results
in a lot of stale .lo files being left around in /tmp. Worse, libtool
creates a /tmp/.libs directory which we can't easily clean up.
Put all our temporary files in a single temporary directory created
as a subdirectory of the build directory, so we can easily clean it up,
and don't need fragile or complicated code for creation to avoid it
clashing with temporary directories from other instances of QEMU
configure or being subject to attack from adversaries who can write
to /tmp.
Since the temporaries now live in the build tree, we have no
need to jump through hoops with a trap handler to try to remove
them when configure exits; this fixes some weird bugs where hitting
^C during a configure run wouldn't actually make it stop, because
we would run the trap handler but then not stop. (It is possible
to get the trap handler semantics right but it is convoluted largely
because of bugs in dash, so it is simpler to just avoid it.)
Note that "temporary files go in the build directory, not /tmp" is
the way autoconf behaves.

The configure option --with-gtkabi=3.0 is still supported, but no longer
needed when GTK+-2.0 is missing. When no GTK+ ABI is selected by the
user, configure first tries 2.0, then 3.0.

available for GTK+ 3.0. Now building on these platforms is a little bit

Currently all what's needed for single file libcacard/vcard_emul_nss.c

together with the libs is added to global QEMU_CFLAGS and libs_softmmu.
Use the cflags only where really used (for two mentioned files), and
libs only where needed.
While at it, rename variables to better reflect reality: libcacard_*
is really nss_*.
This needs a bit more tweaking: $(NSS_LIBS) should not contain $glib_libs

When source directory can be arrived at by two paths,
configure might misdetect an out of tree build.
The simplest way to trigger the problem is running
configure using a full path. E.g. (<firstpath> refers to qemu source
tree):
ln -s <firstpath> <secondpath>
cd <firstpath>
<secondpath>/configure
A more practical way is when make runs configure automatically:
1. cd <firstpath>/; ./configure
SRC_PATH=<firstpath>/ is written into config_host.mak
2. cd <secondpath>/; touch configure; make
make now runs <firstpath>/configure, so configure
assumes it's an out of tree build
When this happens configure overwrites parts of
the current tree with symlinks.
Make the test more robust: look for configure
in the current directory.
If there - we know it's a source build!

--enable-uname-release was a rather heavyweight hammer, as it allows
providing values less that UNAME_MINIMUM_RELEASE. Also, it affects
all built linux-user targets, which in most cases is not what user
wants.
Now that we have UNAME_MINIMUM_RELEASE for all linux-user platforms,
we can drop --enable-uname-release and the related CONFIG_UNAME_RELEASE
define.
Users can still override the variable with QEMU_UNAME=2.6.32 or -r
command line option. If distributors need to update a minimum version
for a specific target, it can be done by updating UNAME_MINIMUM_RELEASE.

MacOSX doesn't pull .o files from .a archives if the symbol that it
requires is one which the .o file defines as a common symbol.
(Common symbols are those declared without "extern"; the linker
will merge together common symbols with the same name, so
redeclaring the same variable in two compilation units results in
them referring to the same symbol rather than a compilation error).
This MacOSX difference from traditional linker behaviour means that
"make check" produces link errors:
Undefined symbols for architecture x86_64:
"_cur_mon", referenced from:
_error_vprintf in libqemuutil.a(qemu-error.o)
_error_printf in libqemuutil.a(qemu-error.o)
_error_printf_unless_qmp in libqemuutil.a(qemu-error.o)
_error_print_loc in libqemuutil.a(qemu-error.o)
_error_report in libqemuutil.a(qemu-error.o)
ld: symbol(s) not found for architecture x86_64
in this case because "cur_mon" is a common symbol in
libqemustub.a(mon-set-error.o).
In QEMU we don't make any use at all of the common symbol
functionality, so we can avoid this problem entirely simply
by compiling with -fno-common. Enable this option for all
builds, not just MacOSX, so that if we ever inadvertently
introduce multiple definitions of some variable that will
be immediately spotted as a build error rather than only
breaking the MacOSX build.

gcc's C++ compiler complains about being passed some -W options
which make sense for C but not for C++. This means we mustn't try
a C++ compile with QEMU_CFLAGS, but only with a filtered version
that removes the offending options. This filtering was already being
done for uses of C++ in the build itself, but was omitted for the
"does C++ work?" configure test. This only showed up when doing
builds which explicitly enabled -Werror with --enable-werror,
because the "do the compilers work" tests were mistakenly placed
above the "default werror based on whether compiling from git" code.
Another error in this category is that clang warns if you ask it to
compile C++ code from a file named "foo.c". Further, because we
were running do_cc in a subshell in the condition part of an "if",
the error_exit inside do_compiler wouldn't terminate configure and
we would plunge on regardless. Fix this complex of errors:
1. Move the default-werror code up so that there are no invocations
of compile_object and friends between it and the point where we
set $werror explicitly based on the --enable-werror command line
option.
2. Provide a mechanism for filtering QEMU_CFLAGS to create
QEMU_CXXFLAGS, and use it for the test we run here.
3. Provide a do_cxx function to run a test with the C++ compiler
rather than doing cute tricks with subshells and do_cc.
4. Use a new temporary file TMPCXX for the C++ program fragment.

Add support for AArch32 CRC32 and CRC32C instructions added in ARMv8
and add a CPU feature flag to enable these instructions.
The CRC32-C implementation used is the built-in qemu implementation
and The CRC-32 implementation is from zlib. This requires adding zlib
to LIBS to ensure it is linked for the linux-user binary.

gmodule-2.0's pkg-config files include -Wl,--export-dynamic, which breaks
static builds. It is a glib bug, but we need to support --static builds for
the linux-user targets, and in the end all that is needed to fix this is:
* outlaw --enable-modules --static, which makes little sense anyway
* only include gmodule-2.0's cflags and ldflags if --enable-modules is
specified on the command line.

This patch fixes configure so that the netmap backend is not compiled in if the
host doesn't support an API version >= 11. A version upper bound (15) has been
added so that the netmap API can be extended with some minor features without
requiring QEMU code modifications.
Moreover, some changes have been done to net/netmap.c in order to reflect the
current netmap API/ABI (11).
The NETMAP_WITH_LIBS macro makes possible to include some utilities (e.g.
netmap ring macros, D(), RD() and other high level functions) through the netmap
headers. In this way we get rid of the D and RD macro definitions in the QEMU
code, and we open the way for further code simplifications that will be
introduced by future patches.

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

Add necessary rules and flags for shared object generation.
The new rules introduced here are:
1) %.o in $(common-obj-m) is compiled to %.o, then linked to %.so.
2) %.mo in $(common-obj-m) is the placeholder for %.so for pattern
matching in Makefile. It's linked to "-shared" with all its dependencies
(multiple *.o) as input. Which means the list of depended objects must
be specified in each sub-Makefile.objs:
foo.mo-objs := bar.o baz.o qux.o
in the same style with foo.o-cflags and foo.o-libs. The objects here
will be prefixed with "$(obj)/" if it's a subdirectory Makefile.objs.
3) For all files ending up in %.so, the following is added automatically:
foo.o-cflags += -fPIC -DBUILD_DSO
Also introduce --enable-modules in configure, the option will enable
support of shared object build. Otherwise objects are static linked to
executables.

Makefile.target includes rule.mak and unnested common-obj-y, then prefix
them with '../', this will ignore object specific QEMU_CFLAGS in subdir
Makefile.objs:
$(obj)/curl.o: QEMU_CFLAGS += $(CURL_CFLAGS)
Because $(obj) here is './block', instead of '../block'. This doesn't
hurt compiling because we basically build all .o from top Makefile,
before entering Makefile.target, but it will affact arriving per-object
libs support.
The starting point of $(obj) is passed in as argument of unnest-vars, as
well as nested variables, so that different Makefiles can pass in a

This resolves the build issue with building the ROMs on OpenBSD on x86 archs.
As of OpenBSD 5.3 the compiler builds PIE binaries by default and thus the
whole OS/packages and so forth. The ROMs need to have PIE disabled.
Check in configure whether the compiler supports the flags for disabling
PIE, and if it does then use them for building the ROMs. This fixes the
following buildbot failure:

This patch adds native support for accessing images on NFS
shares without the requirement to actually mount the entire
NFS share on the host.
NFS Images can simply be specified by an url of the form:
nfs://<host>/<export>/<filename>[?param=value[¶m2=value2[&...]]]
For example:
qemu-img create -f qcow2 nfs://10.0.0.1/qemu-images/test.qcow2
You need LibNFS from Ronnie Sahlberg available at:
git://github.com/sahlberg/libnfs.git
for this to work.
During configure it is automatically probed for libnfs and support
is enabled on-the-fly. You can forbid or enforce libnfs support
with --disable-libnfs or --enable-libnfs respectively.
Due to NFS restrictions you might need to execute your binaries
as root, allow them to open priviledged ports (<1024) or specify
insecure option on the NFS server.
For additional information on ROOT vs. non-ROOT operation and URL
format + parameters see:
https://raw.github.com/sahlberg/libnfs/master/README
Supported by qemu are the uid, gid and tcp-syncnt URL parameters.

Enable KVM if the host and target CPU are both aarch64. Note
that host aarch64 + target arm is not valid for KVM acceleration:
the 64 bit kernel does not support the ioctl interface for
32 bit CPUs. 32 bit VMs on 64 bit hosts need to be created
using the 64 bit ioctl interface; when QEMU supports this it
will be on the arch64-softmmu target with a -cpu parameter for
a 32 bit CPU, which is still an aarch64/aarch64 combination
as far as configure is concerned.

This patch adds support for a network backend based on netmap.
netmap is a framework for high speed packet I/O. You can use it
to build extremely fast traffic generators, monitors, software
switches or network middleboxes. Its companion software switch
VALE lets you interconnect virtual machines.
netmap and VALE are implemented as a non-intrusive kernel module,
support NICs from multiple vendors, are part of standard FreeBSD
distributions and available in source format for Linux too.
To compile QEMU with netmap support, use the following configure
options:
./configure [...] --enable-netmap --extra-cflags=-I/path/to/netmap/sys
where "/path/to/netmap" contains the netmap source code, available at
http://info.iet.unipi.it/~luigi/netmap/
The same webpage contains more information about the netmap project
(together with papers and presentations).

Our rules.mak adds '-rR' to MAKEFLAGS to indicate that we will be
explicitly specifying everything and not relying on any default
variables or rules. However we were accidentally relying on the
default ARFLAGS ("rv"). This went unnoticed because of a bug in
GNU Make 3.82 and earlier which meant that adding -rR to MAKEFLAGS
only affected submakes, not the currently running instance.
Explicitly set ARFLAGS in config-host.mak, in the same way we
handle CFLAGS and LDFLAGS; this will allow us to work with
Make 4.0.

Commit 1d984a67a9 added the -B switch
unconditionally. This breaks Python versions before 2.6 which don't
support that switch.
Now configure adds -B only if it is accepted by the Python interpreter.
This modification introduces a small incompatibility because -B might now
also be added when configure was called with --python=PYTHON_INTERPRETER.

The 'gthread' coroutine backend was written before the freelist (aka
pool) existed in qemu-coroutine.c.
This means that every thread is expected to exit when its coroutine
terminates. It is not possible to reuse threads from a pool.
This patch automatically disables the pool when 'gthread' is used. This
allows the 'gthread' backend to work again (for example,
tests/test-coroutine completes successfully instead of hanging).
I considered implementing thread reuse but I don't want quirks like CPU
affinity differences due to coroutine threads being recycled. The
'gthread' backend is a reference backend and it's therefore okay to skip
the pool optimization.
Note this patch also makes it easy to toggle the pool for benchmarking
purposes:
./configure --with-coroutine-backend=ucontext \
--disable-coroutine-pool

Adds VSS provider and requester as a qga-vss.dll, which is loaded by
Windows VSS service as well as by qemu-ga.
"provider.cpp" implements a basic stub of a software VSS provider.
Currently, this module only relays a frozen event from VSS service to the
agent, and thaw event from the agent to VSS service, to block VSS process
to keep the system frozen while snapshots are taken at the host.
To register the provider to the guest system as COM+ application, the type
library (.tlb) for qga-vss.dll is required. To build it from COM IDL (.idl),
VisualC++, MIDL and stdole2.tlb in Windows SDK are required. This patch also
adds pre-compiled .tlb file in the repository in order to enable
cross-compile qemu-ga.exe for Windows with VSS support.
"requester.cpp" provides the VSS requester to kick the VSS snapshot process.
Qemu-ga.exe works without the DLL, although fsfreeze features are disabled.
These functions are only supported in Windows 2003 or later. In older
systems, fsfreeze features are disabled.
In several versions of Windows which don't support attribute
VSS_VOLSNAP_ATTR_NO_AUTORECOVERY, DoSnapshotSet fails with error
VSS_E_OBJECT_NOT_FOUND. In this patch, we just ignore this error.
To solve this fundamentally, we need a framework to handle mount writable
snapshot on guests, which is required by VSS auto-recovery feature
(cleanup phase after a snapshot is taken).

To enable VSS support in qemu-ga for Windows, header files included in
VSS SDK are required.
The VSS support is enabled by the configure option like below:
./configure --with-vss-sdk="/path/to/VSS SDK"
If the path is omitted, it tries to search the headers from default paths
and VSS support is enabled only if the SDK is found.
VSS support is disabled if --without-vss-sdk or --with-vss-sdk=no is
specified.
VSS SDK is available from:
http://www.microsoft.com/en-us/download/details.aspx?id=23490
To cross-compile using mingw, you need to setup the SDK on Windows
environments to extract headers. You can also extract the SDK headers on
POSIX environments using scripts/extract-vss-headers and msitools.
In addition, --with-win-sdk="/path/to/Windows SDK" option is also added to
specify path to Windows SDK, which may be used for native-compile of .tlb
file of qemu-ga VSS provider. However, this is usually unnecessary because
pre-compiled .tlb file is included.

When a Python script is run, Python normally writes bytecode into a .pyc file.
QEMU's build process uses several Python scripts which are called from
configure or make.
The generated .pyc files take disk space without being of much use, because
those scripts are short, not time critical and only called a few times.
Python's option -B disables writing of .pyc files. QEMU now uses "python -B"
as default, but it is still possible to choose a different call by passing
--python=PYTHON to configure.

Some versions of clang will warn about adding integers to strings:

~~~~~~~^~~~~~~~~~~~~~
disas/i386.c:4753:23: note: use array indexing to silence this warning
oappend ("%es:" + intel_syntax);

disas/i386.c uses this idiom to to skip a "%" prefix if using intel
rather than AT&T syntax. This seems like a reasonable thing to do,

Now all linux-user targets support building with NPTL, we can make it
mandatory. This is a good idea because:
* NPTL is no longer new and experimental; it is completely standard
* in practice, linux-user without NPTL is nearly useless for
binaries built against non-ancient glibc
* it allows us to delete the rather untested code for handling
the non-NPTL configuration
Note that this patch leaves the CONFIG_USE_NPTL ifdefs in the
bsd-user codebase alone. This makes no change for bsd-user, since
our configure test for NPTL had a "#include <linux/futex.h>"
which means bsd-user would never have been compiled with
CONFIG_USE_NPTL defined, and it still is not.

Commit 7791dba3ec broke compilation on MacOSX, because it introduced
a new include of util.h. On MacOSX this includes pwd.h which in turn
includes the system uuid/uuid.h, which causes a compile failure if
QEMU was configured without CONFIG_UUID due to a conflict between
the system header and our fallback versions:
block/vdi.c:124:20: error: static declaration of 'uuid_generate'
follows non-static declaration
static inline void uuid_generate(uuid_t out)
^
/usr/include/uuid/uuid.h:63:6: note: previous declaration is here
void uuid_generate(uuid_t out);
^
Fix this breakage by improving configure's check for uuid to work on
MacOSX (where there is no need to link in a separate libuuid).
Note that if the user explicitly runs configure with '--disable-uuid'
on MacOSX then QEMU will fail to compile.

This patch adds a ftrace tracing backend which sends trace event to
ftrace marker file. You can effectively compare qemu trace data and
kernel(especially, kvm.ko when using KVM) trace data.
The ftrace backend is restricted to Linux only.
To try out the ftrace backend:
$ ./configure --trace-backend=ftrace
$ make
if you use KVM, enable kvm events in ftrace:
# sudo echo 1 > /sys/kernel/debug/tracing/events/kvm/enable
After running qemu by root user, you can get the trace:
# cat /sys/kernel/debug/tracing/trace

Reimplement usb-host on top of libusb.
Reasons to do this:
(1) Largely rewritten from scratch, nice opportunity to kill historical
cruft.
(2) Offload usbfs handling to libusb.
(3) Have a single portable code base instead of bsd + linux variants.
(4) Bring usb-host support to any platform supported by libusbx.
For now this goes side-by-side to the existing code. That is only to
simplify regression testing though, at the end of the day I want remove
the old code and support libusb exclusively. Merge early in 1.5 cycle,
remove the old code after 1.5 release or something like this.
Thanks to qdev the old and new code can coexist nicely on linux. Just
use "-device usb-host-linux" to use the old linux driver instead of the
libusb one (which takes over the "usb-host" name).
The bsd driver isn't qdev'ified so it isn't that easy for bsd.
I didn't bother making it runtime switchable, so you have to rebuild
qemu with --disable-libusb to get back the old code.

qemu-system-x86_64 -drive file=ssh://hostname/some/image
QEMU will ssh into 'hostname' and open '/some/image' which is made
available as a standard block device.
You can specify a username (ssh://user@host/...) and/or a port number
(ssh://host:port/...). You can also use an alternate syntax using
properties (file.user, file.host, file.port, file.path).
Current limitations:
- Authentication must be done without passwords or passphrases, using
ssh-agent. Other authentication methods are not supported.
- Uses a single connection, instead of concurrent AIO with multiple
SSH connections.
This is implemented using libssh2 on the client side. The server just
requires a regular ssh daemon with sftp-server support. Most ssh
daemons on Unix/Linux systems will work out of the box.

The CONFIG_DEBUG_EXEC define compiles out a single qemu_log_mask()
call, which is a pretty trivial cost even for something in the main
cpu_exec() loop. Having this be conditionally defined means that
'-d exec' on a non-debug build will silently do nothing. Drop the
define and the configure machinery that sets it, in favour of just
always allowing this log option to be enabled at runtime. As a
concession to the mainloopiness, we use qemu_loglevel_mask()+qemu_log()
rather than qemu_log_mask() to avoid the function call overhead.
Note that DEBUG_DISAS is always defined, so removing the
'|| defined(CONFIG_DEBUG_EXEC)' from those conditionals makes
no behavioural change for that logging.

The gthread coroutine backend is broken and does not produce a working
QEMU; it is only useful for some very limited debugging situations.
Clean up the backend selection logic in configure so that it now runs
"if on windows use windows; else prefer ucontext; else sigaltstack".
To do this we refactor the configure code to separate out "test
whether we have a working ucontext", "pick a default if user didn't
specify" and "validate that user didn't specify something invalid",
rather than having all three of these run together. We also simplify
the Makefile logic so it just links in the backend the configure
script selects.

This is minimalistic and just contains the basic widget infrastructure. The GUI
consists of a menu and a GtkNotebook. To start with, the notebook has its tabs
hidden which provides a UI that looks very similar to SDL with the exception of
the menu bar.
The menu bar allows a user to toggle the visibility of the tabs. Cairo is used
for rendering.
I used gtk-vnc as a reference. gtk-vnc solves the same basic problems as QEMU
since it was originally written as a remote display for QEMU. So for the most
part, the approach to rendering and keyboard handling should be pretty solid for
GTK.

This patch adds basic Websocket Protocol version 13 - RFC 6455 - support
to QEMU VNC. Binary encoding support on the client side is mandatory.
Because of the GnuTLS requirement the Websockets implementation is
optional (--enable-vnc-ws).
To activate Websocket support the VNC option "websocket"is used, for
example "-vnc :0,websocket".
The listen port for Websocket connections is (5700 + display) so if
QEMU VNC is started with :0 the Websocket port would be 5700.
As an alternative the Websocket port could be manually specified by
using ",websocket=<port>" instead.
Parts of the implementation base on Anthony Liguori's QEMU Websocket
patch from 2010 and on Joel Martin's LibVNC Websocket implementation.

Buffered bulk mode is intended for bulk *input* endpoints, where the data is
of a streaming nature (not part of a command-response protocol). These
endpoints' input buffer may overflow if data is not read quickly enough.
So in buffered bulk mode the usb-host takes care of the submitting and
re-submitting of bulk transfers.
Buffered bulk mode is necessary for reliable operation with the bulk in
endpoints of usb to serial convertors. Unfortunatelty buffered bulk input
mode will only work with certain devices, therefor this patch also adds a
usb-id table to enable it for devices which need it, while leaving the
bulk ep handling for other devices unmodified.
Note that the bumping of the required usbredir from 0.5.3 to 0.6 does
not mean that we will now need a newer usbredir release then qemu-1.3,

Default to 'cc' as our compiler, rather than 'gcc'. We used to have
to insist on gcc when we still kept the CPU env in a fixed global
register, but this is no longer necessary and we will now compile OK
on clang as well as gcc. Using 'cc' should generally result in us
using the most standard and maintained system compiler for the
platform. (For instance on newer MacOS X 'gcc' exists but is an
elderly compiler provided mostly for legacy reasons, and 'cc'
(which is clang) is definitely the better choice.) On Linux there
will generally be no user-visible change since cc will be gcc.
This changeover necessitates a slight reworking of how we set the
'cc' variable, because GNU cross toolchains generally provide a
'${cross_prefix}gcc' but not a '${cross_prefix}cc'.

gcc will silently accept unrecognized -Wno-wombat warning suppression
options (it only mentions them if it has to print a compiler warning
for some other reason). Since we already run a check for whether gcc
recognizes the warning options we use, we can easily make this use
the positive sense of the option when checking for support for the
suppression option. This doesn't have any effect except that it avoids
gcc emitting extra messages about unrecognized command line options
when it is printing other warning messages.

and build with the usb-redir device. Due to the API change there will be
some compiler warnings, but the build will succeed, however the usb-redir
device will be broken on 32 bit machines.
To solve this a new usbredir-0.5.2 release is coming, which renames the
libusbredirparser.pc file to libusbredirparser-0.5.pc, so that it will no
longer fulfill the pkg-config check of the qemu-1.2 and older releases,
stopping the (silent) breakage. This patch adjusts qemu master's configure
to properly detect the new usbredir release.

-Not only use the new .pc name in the check but also when getting cflags

valgrind with kvm produces a big amount of false positives regarding
"Conditional jump or move depends on uninitialised value(s)". This
happens because the guest memory is allocated with qemu_vmalloc which
boils down posix_memalign etc. This function is (correctly) considered
by valgrind as returning undefined memory.
Since valgrind is based on jitting code, it will not be able to see
changes made by the guest to guest memory if this is done by KVM_RUN,
thus keeping most of the guest memory undefined.
Now lots of places in qemu will then use guest memory to change behaviour.
To avoid the flood of these messages, lets declare the whole guest
memory as defined. This will reduce the noise and allows us to see real
problems.
In the future we might want to make this conditional, since there
is actually something that we can use those false positives for:
These messages will point to code that depends on guest memory, so
we can use these backtraces to actually make an audit that is focussed
only at those code places. For normal development we dont want to
see those messages, though.

MacOSX 10.8 ("Mountain Lion") requires us to compile our one
Objective-C source file with clang even if the rest of QEMU
requires a real gcc, because the system headers we use make
use of Apple's "Blocks" extension to C/ObjC, and mainline
gcc doesn't support that. Since we only need to use a true
gcc for the parts of QEMU that use the fixed-register
env variable, we can simply use clang to build the ObjC
file: it will link to the gcc-built objects with no problems.
Add the necessary support for an OBJCC variable in the
makefile and configure machinery; we default to clang
if we have it, otherwise whatever CC is (since gcc
might be the Apple gcc which does support Blocks).

Don't run configure tests with -Werror in the compiler flags. The idea
of -Werror is that it makes problems very obvious to developers, so
they get fixed quickly. However, when running configure tests, failures
due to -Werror are far from obvious -- they simply result in the test
quietly failing when it should have passed. Not using -Werror is in
line with recommended practice in the Autoconf world.
This commit is essentially backing out the changes in commit 417c9d72.
Instead we fix the problem that commit was trying to address in a
different way: we add -Werror only for the test of the nss headers,
with a comment that this is specifically intended to detect a bug
in some releases of nss.
We also have to clean up a bug in the smartcard test where it was
trying to include smartcard_cflags in the test compile flags: this
would always result in a failure with -Werror, because they include
an escaped "$(SRC_PATH)" which is only valid when used in the final

The MinGW toolchain on w32/w64 hosts does not create symbolic links,
but implements 'ln -s' similar to 'cp -r'.
In incremental out of tree builds, this resulted in files which
were not updated when their counterparts in the QEMU source tree
changed. Especially for Makefile* this happened very often.
With this patch, the 'symlinked' files are now always updated for
out of tree builds. Similar code was already used for the symbolic
link of libcacard/Makefile.
The symlink macro always removes the target before it is created
again, therefore the rm command for libcacard/Makefile was redundant
and is removed now.
Macro symlink is also used with directories. To remove them on w32
hosts, a recursive rm is needed.
v2:
Quote arguments in shell function symlink, and also quote any argument
which is passed to symlink and which contains macros. This should reduce
the chance of accidents caused by rm -rf.

The tracetool script is written in shell and has hit several portability
problems due to shell quirks or external tools across host platforms.
Additionally the amount of string processing and lack of real data
structures makes it tough to implement code generator backends for
tracers that are more complex.
This patch replaces the shell version of tracetool with a Python
version. The new tracetool design is:
scripts/tracetool.py - top-level script
scripts/tracetool/backend/ - tracer backends live here (simple, ust)
scripts/tracetool/format/ - output formats live here (.c, .h)
There is common code for trace-events definition parsing so that
backends can focus on generating code rather than parsing input.
Support for all existing backends (nop, stderr, simple, ust,
and dtrace) is added back in follow-up patches.

Some locale settings let make fail or create wrong results
because tr '[:lower:]' '[:upper:]' which is used to convert
from lower to upper case depends on the locale.
With locale tr_TR.UTF-8, lower case 'i' is not converted to 'I'.
This results in wrong entries in config-host.h like these ones:
#define CONFIG_QEMU_PREFiX "/usr/local"
#define CONFIG_QEMU_BiNDiR "/usr/local/bin"
This problem was reported by Emre Ersin.
The same problem occurs when configure creates the target specific
files config-target.mak. They get wrong declarations:
TARGET_CRiS=y
TARGET_i386=y
TARGET_MiCROBLAZE=y
TARGET_MiPS64=y
TARGET_MiPS=y
TARGET_UNiCORE32=y
It is sufficient to restrict the conversion to the characters a-z.
Using this explicit range avoids the dependency on the locale
settings and is also shorter.

locale, so we must set LC_ALL=C to make sure that we are using

The macro offsetof is defined in stddef.h. It is conforming to
the standards C89, C99 and POSIX.1-2001 (see man page), so it
is a sufficiently old standard.
Therefore chances are very high that QEMU never needs a local
definition of this macro.
osdep.h already includes stddef.h, so this patch simply removes
the unneeded code from the files configure and osdep.h.
If we ever need the local definition again, it should be added
to compiler.h (the macro is usually provided with the compiler,

also check for the presence of the __stub_makecontext macro which

This patch adds the posibility to filter out certain devices from redirecion.
To use this pass the filter property to -device usb-redir. The filter
property takes a string consisting of filter rules, the format for a rule is:
<class>:<vendor>:<product>:<version>:<allow>
-1 can be used to allow any value for a field.
Muliple rules can be concatonated using | as a separator. Note that if
a device matches none of the passed in rules, redirecting it will not be
allowed!
Example:
-device usb-redir,filter='-1:0x0781:0x5567👎0|0x08👎-1👎1'
This example will deny the Sandisk Cruzer Blade being redirected, as it
has a usb id of 0781:5567, it will allow any other usb mass storage devices,
and it will deny any other devices (the default for devices not matching any
of the rules.

The most common use of -net tap is to connect a tap device to a bridge. This
requires the use of a script and running qemu as root in order to allocate a
tap device to pass to the script.
This model is great for portability and flexibility but it's incredibly
difficult to eliminate the need to run qemu as root. The only really viable
mechanism is to use tunctl to create a tap device, attach it to a bridge as
root, and then hand that tap device to qemu. The problem with this mechanism
is that it requires administrator intervention whenever a user wants to create
a guest.
By essentially writing a helper that implements the most common qemu-ifup
script that can be safely given cap_net_admin, we can dramatically simplify
things for non-privileged users. We still support existing -net tap options
as a mechanism for advanced users and backwards compatibility.
Currently, this is very Linux centric but there's really no reason why it
couldn't be extended for other Unixes.
A typical invocation would be similar to one of the following:
qemu linux.img -net bridge -net nic,model=virtio
qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper"
-net nic,model=virtio
qemu linux.img -netdev bridge,id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1
qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper",id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1
The default bridge that we attach to is br0. The thinking is that a distro
could preconfigure such an interface to allow out-of-the-box bridged networking.
Alternatively, if a user wants to use a different bridge, a typical invocation
would be simliar to one of the following:
qemu linux.img -net bridge,br=qemubr0 -net nic,model=virtio
qemu linux.img -net tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0"
-net nic,model=virtio
qemu linux.img -netdev bridge,br=qemubr0,id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1
qemu linux.img -netdev tap,helper="/usr/local/libexec/qemu-bridge-helper --br=qemubr0",id=hn0
-device virtio-net-pci,netdev=hn0,id=nic1

The ideal way to use qemu-bridge-helper is to give it an fscap of using:
setcap cap_net_admin=ep qemu-bridge-helper
Unfortunately, most distros still do not have a mechanism to package files
with fscaps applied. This means they'll have to SUID the qemu-bridge-helper
binary.
To improve security, use libcap to reduce our capability set to just
cap_net_admin, then reduce privileges down to the calling user. This is
hopefully close to equivalent to fscap support from a security perspective.

This patch adds a helper that can be used to create a tap device attached to
a bridge device. Since this helper is minimal in what it does, it can be
given CAP_NET_ADMIN which allows qemu to avoid running as root while still
satisfying the majority of what users tend to want to do with tap devices.
The way this all works is that qemu launches this helper passing a bridge
name and the name of an inherited file descriptor. The descriptor is one
end of a socketpair() of domain sockets. This domain socket is used to
transmit a file descriptor of the opened tap device from the helper to qemu.
The helper can then exit and let qemu use the tap device.

The test for whether the host CPU is supported had several problems:
* the attempt to fall back to TCI was done as a duplicate
test, very late (so "--cpu foo" would fail early but "--cpu unicore32"
would fail late, differently, and after configure had already
printed a lot of output)
* a number of CPUs only supported as guests were included in the
list of CPUs we would accept as valid hosts, which would result
in a late compile failure on those systems rather than a
configure failure or fallback to TCI
* bailing out for an unsupported CPU happened before the main
option parsing, so "configure --help" wouldn't work
Fix these by folding the setting of ARCH into the first test for
supported host CPU, removing spurious guest-only CPU names from it,
and moving the "fall back to TCI" code earlier.

Change the default on x86 Linux hosts to building PIE (position
independent executables); instead of restricting the option to
user-only targets, apply it to all targets.
In addition, set the relocation sections to read-only (relro) when
available; this reduces the attack surface by disallowing changes to
relocation tables at runtime.
While PIE reduces performance and relro increases load time, it
greatly improves security, with the potential to reduce a code
execution vulnerability to a self denial of service.

This provides built-in support for iSCSI to QEMU.
This has the advantage that the iSCSI devices need not be made visible to the host, which is useful if you have very many virtual machines and very many iscsi devices.
It also has the benefit that non-root users of QEMU can access iSCSI devices across the network without requiring root privilege on the host.
This driver interfaces with the multiplatform posix library for iscsi initiator/client access to iscsi devices hosted at
git://github.com/sahlberg/libiscsi.git
The patch adds the driver to interface with the iscsi library.
It also updated the configure script to
* by default, probe is libiscsi is available and if so, build
qemu against libiscsi.
* --enable-libiscsi
Force a build against libiscsi. If libiscsi is not available
the build will fail.
* --disable-libiscsi
Do not link against libiscsi, even if it is available.
When linked with libiscsi, qemu gains support to access iscsi resources such as disks and cdrom directly, without having to make the devices visible to the host.
You can specify devices using a iscsi url of the form :
iscsi://[<username>[:<password>@]]<host>[:<port]/<target-iqn-name>/<lun>
When using authentication, the password can optionally be set with
LIBISCSI_CHAP_PASSWORD="password" to avoid it showing up in the process list

This patch removes redundant shell code and cleans it a little bit.
Shell macro compile_prog takes two arguments:
local_cflags and local ldflags.
$QEMU_CFLAGS is added automatically to the cflags, so there is no need
to pass it as an argument.
It is also unnecessary to pass -Werror twice.
$flag is a compiler warning option, so it should be in local_cflags
instead of local_ldflags.

The QDict unit-tests (check-qdict) will fail when ran on a different
build directory. That's, it only works when ran on the source dir.
This happens because its data file (qdict-test-data.txt) is not
copied to the build dir. Fix it.

Allow overriding the location of Samba's smbd.
Pretty much every OS I look at has some means of
changing this path (patching) so lets just make
it easier for OS developers creating packages
and/or end users to override the location.

Fix install(1) usage to be compatible with OpenBSD's install(1).
When creating a directory via the -d flag the -p flag cannot be
used at the same time. Also in the context of installing QEMU it
doesn't make sense to use the -p flag anyway so use the [default]
-c flag instead.

Enabling the I/O thread by default seems like an important part of declaring
1.0. Besides allowing true SMP support with KVM, the I/O thread means that the
TCG VCPU doesn't have to multiplex itself with the I/O dispatch routines which
currently requires a (racey) signal based alarm system.
I know there have been concerns about performance. I think so far the ones that
have come up (virtio-net) are most likely due to secondary reasons like
decreased batching.
I think we ought to force enabling I/O thread early in 1.0 development and
commit to resolving any lingering issues.

This patch tries to cull any uneeded library dependencies from the guest
agent to improve portability across various distros. We do so by being
as explicit as possible about in-tree dependencies rather than relying
on existing *-obj-y targets, and by manually setting LIBS for the
qemu-ga target to avoid pulling in LIBS_TOOLS libraries discovered by
configure.

guest_agent is not supported for mingw32, so the default value
should be 'no', not 'yes'.
This removes the dependencies to glib-2.0 and python which
makes native and cross builds for w32 much easier (no need
to get and install these extra packages).
It also avoids the problems caused by different bitfield alignment
which is required by glib-2.0.
It is still possible to set guest_agent=yes via configure option.

QAPI will require glib/python, but for now the guest agent is the only
user. For now, make these dependencies an explicit guest agent one, and
give users the option to disable it if need be.
Once QAPI is adopted in core QEMU code, we would basically revert this
patch.
