2020-11-19trace: use STAP_SDT_V2 to work around symbol visibilityStefan Hajnoczi
QEMU binaries no longer launch successfully with recent SystemTap releases. This is because modular QEMU builds link the sdt semaphores into the main binary instead of into the shared objects where they are used. The symbol visibility of semaphores is 'hidden' and the dynamic linker prints an error during module loading: $ ./configure --enable-trace-backends=dtrace --enable-modules ... ... Failed to open module: /builddir/build/BUILD/qemu-4.2.0/s390x-softmmu/../block-curl.so: undefined symbol: qemu_curl_close_semaphore The long-term solution is to generate per-module dtrace .o files and link them into the module instead of the main binary. In the short term we can define STAP_SDT_V2 so dtrace(1) produces a .o file with 'default' symbol visibility instead of 'hidden'. This workaround is small and easier to merge for QEMU 5.2 and downstream backports.

2020-11-17configure: Make "does libgio work" test pull in some actual functionsPeter Maydell
In commit 76346b6264a9b01979 we tried to add a configure check that the libgio pkg-config data was correct, which builds an executable linked against it. Unfortunately this doesn't catch the problem (missing static library dependency info), because a "do nothing" test source file doesn't have any symbol references that cause the linker to pull in .o files from libgio.a, and so we don't see the "missing symbols from libmount" error that a full QEMU link triggers. (The ineffective test went unnoticed because of a typo that effectively disabled libgio unconditionally, but after commit 3569a5dfc11f2 fixed that, a static link of the system emulator on Ubuntu stopped working again.) Improve the gio test by having the test source fragment reference a g_dbus function (which is what is indirectly causing us to end up wanting functions from libmount).

2020-11-12configure: mark vhost-user Linux-onlyStefan Hajnoczi
The vhost-user protocol uses the Linux eventfd feature and is typically connected to Linux kvm.ko ioeventfd and irqfd file descriptors. The protocol specification in docs/interop/vhost-user.rst does not describe how platforms without eventfd support work. The QEMU vhost-user devices compile on other POSIX host operating systems because eventfd usage is abstracted in QEMU. The libvhost-user programs in contrib/ do not compile but we failed to notice since they are not built by default. Make it clear that vhost-user is only supported on Linux for the time being. If someone wishes to support it on other platforms then the details can be added to vhost-user.rst and CI jobs can test the feature to prevent bitrot.

Initially, libudev detection was bundled with --enable-mpath because qemu-pr-helper was the only user of libudev. Recently however the USB U2F emulation has also started using libudev, so add a separate option. This also allows 1) disabling libudev if desired for static builds and 2) for non-static builds, requiring libudev even if multipath support is undesirable. The multipath test is adjusted, because it is now possible to enter it with configurations that should fail, such as --static --enable-mpath --disable-libudev.

Now that the build is done entirely by Meson, there is no need to keep the Makefile conversion. Instead, we can ask Ninja about the targets it exposes and forward them.

2020-10-15block: deprecate the sheepdog block driverDaniel P. Berrangé
This thread from a little over a year ago: http://lists.wpkg.org/pipermail/sheepdog/2019-March/thread.html states that sheepdog is no longer actively developed. The only mentioned users are some companies who are said to have it for legacy reasons with plans to replace it by Ceph. There is talk about cutting out existing features to turn it into a simple demo of how to write a distributed block service. There is no evidence of anyone working on that idea: https://github.com/sheepdog/sheepdog/commits/master No real commits to git since Jan 2018, and before then just some minor technical debt cleanup. There is essentially no activity on the mailing list aside from patches to QEMU that get CC'd due to our MAINTAINERS entry. Fedora packages for sheepdog failed to build from upstream source because of the more strict linker that no longer merges duplicate global symbols. Fedora patches it to add the missing "extern" annotations and presumably other distros do to, but upstream source remains broken. There is only basic compile testing, no functional testing of the driver. Since there are no build pre-requisites the sheepdog driver is currently enabled unconditionally. This would result in configure issuing a deprecation warning by default for all users. Thus the configure default is changed to disable it, requiring users to pass --enable-sheepdog to build the driver.

2020-10-09configure: fix performance regression due to PIC objectsPaolo Bonzini
Because most files in QEMU are grouped into static libraries, Meson conservatively compiles them with -fPIC. This is overkill and produces slowdowns up to 20% on some TCG tests. As a stopgap measure, use the b_staticpic option to limit the slowdown to --enable-pie. https://github.com/mesonbuild/meson/pull/7760 will allow us to use b_staticpic=false and let Meson do the right thing.

2020-10-06configure: don't enable ASLR for --enable-debug Windows buildsMark Cave-Ayland
Unlike other OSs it is not possible for gdb to temporarily disable ASLR when debugging executables on Windows which causes gdb to fail with memory access errors when trying to debug QEMU. Keep ASLR enabled by default on Windows via the --dynamicbase compiler flag except for --enable-debug builds when there is a clear expectation that a functioning gdb is expected at the cost of slightly less security.

2020-10-06configure: consistently pass CFLAGS/CXXFLAGS/LDFLAGS to mesonPaolo Bonzini
Environment variables like CFLAGS are easy to accidentally change. Meson warns if that happens, but in a project with a lot of configuration that is easy to lose. It is also surprising behavior since meson caches -D options and remembers those on reconfiguration (which we rely on, since configure options become -D options). By placing the user-provided CFLAGS, CXXFLAGS and LDFLAGS in the cross file, we at least get consistent behavior. These environment variables are still ugly and not really recommended, but there are distros that rely on them. For the gory details, refer to https://github.com/mesonbuild/meson/issues/4664.

2020-10-06configure: do not clobber environment CFLAGS/CXXFLAGS/LDFLAGSPaolo Bonzini
If the CFLAGS, CXXFLAGS or LDFLAGS variables are present in the environment, any modification made within the configure script is passed down to Meson. This is particularly undesirable for the "-pie" option, since it overrides "-shared" and thus messes up the linker flags for shared modules. Using a separate variable therefore fixes the bug, while clarifying that the scope of these CFLAGS is just the configure script. We also do not need to pass those variables in config-host.mak; they were only used for printing the summary now that all submodules are built with handwritten Meson rules). For now synthesize CFLAGS in the configuration summary, the next patch will also pass them in a cleaner way using the cross file.
