2021-12-21ui: add a D-Bus display backendMarc-André Lureau
The "dbus" display backend exports the QEMU consoles and other UI-related interfaces over D-Bus. By default, the connection is established on the session bus, but you can specify a different bus with the "addr" option. The backend takes the "org.qemu" service name, while still allowing further instances to queue on the same name (so you can lookup all the available instances too). It accepts any number of clients at this point, although this is expected to evolve with options to restrict clients, or only accept p2p via fd passing. The interface is intentionally very close to the internal QEMU API, and can be introspected or interacted with busctl/dfeet etc: $ ./qemu-system-x86_64 -name MyVM -display dbus $ busctl --user introspect org.qemu /org/qemu/Display1/Console_0 org.qemu.Display1.Console interface - - - .RegisterListener method h - - .SetUIInfo method qqiiuu - - .DeviceAddress property s "pci/0000/01.0" emits-change .Head property u 0 emits-change .Height property u 480 emits-change .Label property s "VGA" emits-change .Type property s "Graphic" emits-change .Width property u 640 emits-change [...] See the interfaces XML source file and Sphinx docs for the generated API documentations.

2021-11-16nbd/server: Add --selinux-label optionRichard W.M. Jones
Under SELinux, Unix domain sockets have two labels. One is on the disk and can be set with commands such as chcon(1). There is a different label stored in memory (called the process label). This can only be set by the process creating the socket. When using SELinux + SVirt and wanting qemu to be able to connect to a qemu-nbd instance, you must set both labels correctly first. For qemu-nbd the options to set the second label are awkward. You can create the socket in a wrapper program and then exec into qemu-nbd. Or you could try something with LD_PRELOAD. This commit adds the ability to set the label straightforwardly on the command line, via the new --selinux-label flag. (The name of the flag is the same as the equivalent nbdkit option.) A worked example showing how to use the new option can be found in this bug: https://bugzilla.redhat.com/show_bug.cgi?id=1984938 Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1984938 Signed-off-by: Richard W.M.

2021-10-14configure: automatically parse command line for meson -D optionsPaolo Bonzini
Right now meson_options.txt lists about 90 options. Each option needs code in configure to parse it and pass the option down to Meson as a -D command-line argument; in addition the default must be duplicated between configure and meson_options.txt. This series tries to remove the code duplication by generating the case statement for those --enable and --disable options, as well as the corresponding help text. About 80% of the options can be handled completely by the new mechanism. Eight meson options are not of the --enable/--disable kind. Six more need to be parsed in configure for various reasons documented in the patch, but they still have their help automatically generated. The advantages are: - less code in configure - parsing and help is more consistent (for example --enable-blobs was not supported) - options are described entirely in one place, meson_options.txt. This make it more attractive to use Meson options instead of hand-crafted configure options and config-host.mak A few options change name: --enable-tcmalloc and --enable-jemalloc become --enable-malloc={tcmalloc,jemalloc}; --disable-blobs becomes --disable-install-blobs; --enable-trace-backend becomes --enable-trace-backends. However, the old names are allowed for backwards compatibility. Message-Id: <20211007130829.632254-19-pbonzini@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2021-10-14configure, meson: move audio driver detection to MesonPaolo Bonzini
This brings a change that makes audio drivers more similar to all other modules. All drivers are built by default, while --audio-drv-list only governs the default choice of the audio driver. Meson options are added to disable the drivers, and the next patches will fix the help messages and command line options, and especially make the non-default drivers available via -audiodev.

2021-01-02configure,meson: support Control-Flow IntegrityDaniele Buono
This patch adds a flag to enable/disable control flow integrity checks on indirect function calls. This feature only allows indirect function calls at runtime to functions with compatible signatures. This feature is only provided by LLVM/Clang, and depends on link-time optimization which is currently supported only with LLVM/Clang >= 6.0 We also add an option to enable a debugging version of cfi, with verbose output in case of a CFI violation. CFI on indirect function calls does not support calls to functions in shared libraries (since they were not known at compile time), and such calls are forbidden. QEMU relies on dlopen/dlsym when using modules, so we make modules incompatible with CFI. All the checks are performed in meson.build. configure is only used to forward the flags to meson Signed-off-by: Daniele Buono <dbuono@linux.vnet.ibm.com> Message-Id: <20201204230615.2392-5-dbuono@linux.vnet.ibm.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
