2016-04-19block/gluster: prevent data loss after i/o errorJeff Cody
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.

2016-03-17crypto: add support for PBKDF2 algorithmDaniel P. Berrange
The LUKS data format includes use of PBKDF2 (Password-Based Key Derivation Function). The Nettle library can provide an implementation of this, but we don't want code directly depending on a specific crypto library backend. Introduce a new include/crypto/pbkdf.h header which defines a QEMU API for invoking PBKDK2. The initial implementations are backed by nettle & gcrypt, which are commonly available with distros shipping GNUTLS. The test suite data is taken from the cryptsetup codebase under the LGPLv2.1+ license. This merely aims to verify that whatever backend we provide for this function in QEMU will comply with the spec.

2016-02-10xen: drop support for Xen 4.1 and older.Ian Campbell
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.

2016-02-09configure: sanity check the glib library that pkg-config findsDaniel P. Berrange
Developers on 64-bit machines will often try to perform a 32-bit build of QEMU by running ./configure --extra-cflags="-m32" Unfortunately if PKG_CONFIG_LIBDIR is not set to point to the location of the 32-bit pkg-config files, then configure will silently pick up the 64-bit pkg-config files and still succeed. This causes a problem for glib because it means QEMU will be pulling in /usr/lib64/glib-2.0/include/glibconfig.h instead of /usr/lib/glib-2.0/include/glibconfig.h This causes problems because the 'gsize' type (defined as 'unsigned long') will no longer be fully compatible with the 'size_t' type (defined as 'unsigned int'). Although both are the same size, the compiler refuses to allow casts from 'unsigned long *' to 'unsigned int *' as they are different pointer types. This results in non-obvious compiler errors when building QEMU eg qga/commands-posix.c: In function ‘qmp_guest_set_user_password’: qga/commands-posix.c:1912:55: error: passing argument 2 of ‘g_base64_decode’ from incompatible pointer type [-Werror=incompatible-pointer-types] rawpasswddata = (char *)g_base64_decode(password, &rawpasswdlen); ^ In file included from /usr/include/glib-2.0/glib.h:35:0, from qga/commands-posix.c:14: /usr/include/glib-2.0/glib/gbase64.h:52:9: note: expected ‘gsize * {aka long unsigned int *}’ but argument is of type ‘size_t * {aka unsigned int *}’ guchar *g_base64_decode (const gchar *text, ^ cc1: all warnings being treated as errors To detect this problem, add a check to configure that verifies that GLIB_SIZEOF_SIZE_T matches sizeof(size_t). If this fails print a warning suggesting that the dev probably needs to set PKG_CONFIG_LIBDIR. On Fedora x86_64 it passes with any of: # ./configure # PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig ./configure --extra-cflags="-m32" # PKG_CONFIG_LIBDIR=/usr/lib64/pkgconfig ./configure --extra-cflags="-m64" And fails with a mis-match # PKG_CONFIG_LIBDIR=/usr/lib64/pkgconfig ./configure --extra-cflags="-m32" # PKG_CONFIG_LIBDIR=/usr/lib/pkgconfig ./configure --extra-cflags="-m64" ERROR: sizeof(size_t) doesn't match GLIB_SIZEOF_SIZE_T.

2016-01-26xen: make it possible to build without the Xen PV domain builderIan Campbell
Until the previous patch this relied on xc_fd(), which was only implemented for Xen 4.0 and earlier. Given this wasn't working since Xen 4.0 I have marked this as disabled by default. Removing this support drops the use of a bunch of symbols from libxenctrl, specifically: - xc_domain_create - xc_domain_destroy - xc_domain_getinfo - xc_domain_max_vcpus - xc_domain_setmaxmem - xc_domain_unpause - xc_evtchn_alloc_unbound - xc_linux_build This is another step towards only using Xen libraries which provide a stable inteface.

2016-01-26xen: Use stable library interfaces when they are available.Ian Campbell
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.

2015-12-04configure: use appropriate code fragment for -fstack-protector checksRodrigo Rebello
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.

2015-11-05configure: disable FORTIFY_SOURCE under clangJohn Snow
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.

2015-11-04configure: disallow ccache during compile testsJohn Snow
If the user is using ccache during the configuration step, it may interfere with some of the configuration tests, particularly the "Is ccache interfering with macro analysis" step, which is a bit of a poetic problem. 1) Disallow ccache from reading from the cache during configure, but don't disable it entirely to allow us to see if it causes other problems. 2) Force off CCACHE_CPP2 during the ccache test to get a deterministic answer over whether or not we need to enable that feature later.

2015-11-03ui/opengl: Reduce build required libraries for openglOGAWA Hirofumi
We now use epoxy to load opengl libraries. This means we don't need to link opengl libraries directly if interfaces handled by epoxy. With this, we just need epoxy headers and epoxy's *.so to build. Tested with epoxy-1.3.1. - sdl2/gtk/console egl stuff doesn't require other than epoxy - milkymist-tmu2 glx stuff doesn't require other than epoxy (lm32 test is limited, because can't find mmone-bios.bin, so just test to load libGL with "./lm32-softmmu/qemu-system-lm32 -M milkymist,accel=qtest") Signed-off-by: OGAWA Hirofumi <hirofumi@mail.parknet.co.jp> [ lm32 tested by kraxel ] Signed-off-by: Gerd Hoffmann <kraxel@redhat.com>

2015-10-22configure: avoid polluting global CFLAGS with tasn1 flagsDaniel P. Berrange
The previous commit commit 9a2fd4347c40321f5cbb4ab4220e759fcbf87d03 Author: Daniel P. Berrange <berrange@redhat.com> Date: Mon Apr 13 14:01:39 2015 +0100 crypto: add sanity checking of TLS x509 credentials defined new variables $TEST_LIBS and $TEST_CFLAGS and used them in tests/Makefile to augment $LIBS and $CFLAGS. Unfortunately this overlooks the fact that tests/Makefile is not executed via recursive-make, it is just pulled into the top level Makefile via an include statement. So rather than just augmenting the compiler/linker flags for tests it polluted the global flags. This is thought to be behind a reported failure when building the pixman module as a sub-module, since global $CFLAGS are passed down to configure in pixman. This change removes the $TEST_LIBS and $TEST_CFLAGS replacing them with $TASN1_LIBS and $TASN1_CFLAGS, setting only against specific objects/executables that need them. Signed-off-by: Daniel P.

2015-10-22crypto: allow use of nettle/gcrypt to be selected explicitlyDaniel P. Berrange
Currently the choice of whether to use nettle or gcrypt is made based on what gnutls is linked to. There are times when it is desirable to be able to force build against a specific library. For example, if testing changes to QEMU's crypto code all 3 possible backends need to be checked regardless of what the local gnutls uses. It is also desirable to be able to enable nettle/gcrypt for cipher/hash algorithms, without enabling gnutls for TLS support. This gives two new configure flags, which allow the following possibilities Automatically determine nettle vs gcrypt from what gnutls links to (recommended to minimize number of crypto libraries linked to) ./configure Automatically determine nettle vs gcrypt based on which is installed ./configure --disable-gnutls Force use of nettle ./configure --enable-nettle Force use of gcrypt ./configure --enable-gcrypt Force use of built-in AES & crippled-DES ./configure --disable-nettle --disable-gcrypt Signed-off-by: Daniel P.

2015-10-19build: qemu-ga: add 'qemu-ga' build target for w32Michael Roth
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` Cc: Paolo Bonzini <pbonzini@redhat.com> Cc: Marc-André Lureau <marcandre.lureau@redhat.com> Signed-off-by: Michael Roth <mdroth@linux.vnet.ibm.com>
