2015-07-27configure: Work around broken static pkg-config info for Ubuntu gnutlsPeter Maydell
Unfortunately Ubuntu's pkg-config information for gnutls is broken for the static linking case, and outputs --libs options which the compiler does not recognize. Work around this problem by testing that the --cflags/--libs output will at least allow compilation before enabling gnutls support.

2015-07-07qga: added GuestPCIAddress informationMichael Roth
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. https://support.microsoft.com/en-us/kb/253232 Signed-off-by: Olga Krishtal <okrishtal@virtuozzo.com> Signed-off-by: Denis V.

2015-07-07crypto: introduce new module for computing hash digestsDaniel P. Berrange
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.

2015-05-22configure: Add workaround for ccache and clangJohn Snow
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.

2015-03-19configure: enable kvm on x32Michael Tokarev
Here's a trivial change to enable kvm on x32 architecture. I'm not 100% sure the result works correctly in all cases, but this is a good start and in theory everything should work.

2015-03-17opengl: fix configure testGerd Hoffmann
Re-add the glx compile test to configure. We can't use pkg-config to probe for glx, and as long as milkymist-tmu2 privately uses glx (due to opengl infrastructure in qemu not being ready yet) we must continue to test for glx to avoid build failures.

2015-02-06block/dmg: support bzip2 block entry typesPeter Wu
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.

This efficiently writes zeroes on Linux if the kernel is capable enough. FALLOC_FL_ZERO_RANGE correctly handles all cases, including and not including file expansion.

2015-01-20Xen: Use the ioreq-server API when availablePaul Durrant
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.
