2015-04-28configure: Add support for tcmallocFam Zheng1-0/+24
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: ========================================================== glibc malloc ---------------------------------------------------------- rw bs iodepth bw iops latency read 4k 1 150 38511 24 ---------------------------------------------------------- ========================================================== tcmalloc ---------------------------------------------------------- rw bs iodepth bw iops latency read 4k 1 156 39969 23 ---------------------------------------------------------- Signed-off-by: Fam Zheng <famz@redhat.com> Message-Id: <1427338992-27057-1-git-send-email-famz@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2015-04-13Revert seccomp tests that allow it to be used on non-x86 architecturesPeter Maydell1-7/+2
Unfortunately it turns out that libseccomp 2.2 still does not work correctly on non-x86 architectures; return to the previous configure setup of insisting on libseccomp 2.1 or better and i386/x86_64 and disabling seccomp support in all other situations. This reverts the two commits: * "seccomp: libseccomp version varying according to arch" (commit 896848f0d3e2393905845ef2b244bb2601f9df0c) * "seccomp: update libseccomp version and remove arch restriction" (commit 8e27fc200457e3f2473d0069263774d4ba17bd85) Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Message-id: 1428670681-23032-1-git-send-email-peter.maydell@linaro.org
2015-04-09configure: disable Archipelago by default and warn about libxseg GPLv3 licenseStefan Hajnoczi1-1/+7
libxseg has changed license to GPLv3. QEMU includes GPL "v2 only" code which is not compatible with GPLv3. This means the resulting binaries may not be redistributable! Disable Archipelago (libxseg) by default to prevent accidental license violations. Also warn if linking against libxseg is enabled to remind the user. Note that this commit does not constitute any advice about software licensing. If you have doubts you should consult a lawyer.

2015-03-26seccomp: libseccomp version varying according to archEduardo Otubo1-1/+7
Libseccomp dependency was mandating version 2.2.0 on all architectures and this was causing configure and virt-test to break on non-updates distros. This patch works-around it and give a more flexible way to check the version, giving more time for other distros to update libseccomp version.

2015-02-06block/dmg: support bzip2 block entry typesPeter Wu1-0/+31
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.

2015-01-20Xen: Use the ioreq-server API when availablePaul Durrant1-0/+29
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.

2014-08-09l2tpv3 (configure): it is linux-specificMichael Tokarev1-0/+1
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 this header in the configure test too.

2014-07-10Enforce stack protector usageMiroslav Rezanina1-1/+8
If --enable-stack-protector is used is used, configure script try to use --fstack-protector-strong. In case it's not supported, --fstack-protector-all is enabled. If both protectors are not supported, configure does not use any protector at all without any notification. This patch reports error when user requests stack protector to be used and both protector modes are not supported. Behavior is not changed in case user do not use any of --enable-stack-protector/--disable-stack-protector.

2014-07-01net: add mmsghdr struct check for L2TPV3Gonglei1-0/+16
The mmsghdr struct is only introduced in Linux 2.6.32; add a configure check for it and disable L2TPV3 on hosts which are too old to provide it, rather than simply failing to compile.

2014-07-01configure: Fix -lm test, so that tools can be compiled on hosts that require -lmAlexey Kardashevskiy1-1/+1
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.

2014-06-27configure: Enable out-of-tree iotestsMax Reitz1-0/+12
In order to allow out-of-tree iotests, create a symlink for the check script in the build tree. While doing so, also write configured options relevant to the iotests to common.env in the build tree; currently, this is the command to invoke Python 2.

2014-06-24configure: Enable TPM by default, add --disable-tpmCole Robinson1-1/+4
I don't see why tpm is disabled by default: it doesn't have any external dependencies, or change default behavior. Leaving it disabled is just going to cause it to bit rot. Enable it by default, and add a --disable-tpm option. Signed-off-by: Cole Robinson <crobinso@redhat.com> Signed-off-by: Michael Tokarev <mjt@tls.msk.ru>
