* curl: remove compatibility code, require 7.29.0Paolo Bonzini2021-01-021-7/+2Star
| | | | | | | | | | | | | | cURL 7.16.0 was released in October 2006. Just remove code that is in all likelihood not being used anywhere, and require the oldest version found in currently supported distros, which is 7.29.0 from CentOS 7. pkg-config is enough for QEMU, since it does not need extra information such as the path for certicate authorities. All supported platforms today will all have pkg-config for curl, so we can drop curl-config.

* configure,meson: support Control-Flow IntegrityDaniele Buono2021-01-021-2/+20
| | | | | | | | | | | | | | | | | | | | | | | | | 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>

* configure: add --without-default-featuresAlex Bennée2021-01-021-70/+85
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default QEMU enables a lot of features if it can probe and find the support libraries. It also enables a bunch of features by default. This patch adds the ability to build --without-default-features which can be paired with a --without-default-devices for a barely functional build. The main use case for this is testing our build assumptions and for minimising the amount of stuff you build if you just want to test a particular feature on your relatively slow emulated test system. On it's own I go from: $ ls -lh qemu-system-aarch64 -rwxr-xr-x 1 alex alex 120M Dec 10 12:45 qemu-system-aarch64* $ ldd qemu-system-aarch64 | wc -l 170 to: $ ls -lh qemu-aarch64 -rwxr-xr-x 1 alex alex 43M Dec 10 12:41 qemu-aarch64* $ ldd qemu-system-aarch64 | wc -l 57 which is still able to run my default Debian ARM64 machine with a lot less fat involved.

* configure: Compile with -Wimplicit-fallthrough=2Thomas Huth2020-12-181-0/+1
| | | | | | | | | | | | | | | | Coverity always complains about switch-case statements that fall through the next one when there is no comment in between - which could indicate a forgotten "break" statement. Instead of handling these issues after they have been committed, it would be better to avoid them in the build process already. Thus let's enable the -Wimplicit-fallthrough warning now. The "=2" level seems to be a good compromise between being too strict and too generic about the possible comments, so we'll start with "=2" for now.

* build: -no-pie is no functional linker flagChristian Ehrhardt2020-12-151-3/+0Star
| | | | | | | | | | | | | | | | | | | | | | | | | Recent binutils changes dropping unsupported options [1] caused a build issue in regard to the optionroms. ld -m elf_i386 -T /<<PKGBUILDDIR>>/pc-bios/optionrom//flat.lds -no-pie \ -s -o multiboot.img multiboot.o ld.bfd: Error: unable to disambiguate: -no-pie (did you mean --no-pie ?) This isn't really a regression in ld.bfd, filing the bug upstream revealed that this never worked as a ld flag [2] - in fact it seems we were by accident setting --nmagic). Since it never had the wanted effect this usage of LDFLAGS_NOPIE, should be droppable without any effect. This also is the only use-case of LDFLAGS_NOPIE in .mak, therefore we can also remove it from being added there.

* trace: use STAP_SDT_V2 to work around symbol visibilityStefan Hajnoczi2020-11-191-0/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* | meson: move vhost_user_blk_server to meson.buildStefan Hajnoczi2020-11-121-12/+4Star
|/ | | | | | | | | | | | | | | | | | | | | | | | | | The --enable/disable-vhost-user-blk-server options were implemented in ./configure. There has been confusion about them and part of the problem is that the shell syntax used for setting the default value is not easy to read. Move the option over to meson where the conditions are easier to understand: have_vhost_user_blk_server = (targetos == 'linux') if get_option('vhost_user_blk_server').enabled() if targetos != 'linux' error('vhost_user_blk_server requires linux') endif elif get_option('vhost_user_blk_server').disabled() or not have_system have_vhost_user_blk_server = false endif This patch does not change behavior.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Make it possible to compile out the vhost-user-blk server. It is enabled by default on Linux. Note that vhost-user-server.c depends on libvhost-user, which requires CONFIG_LINUX. The CONFIG_VHOST_USER dependency was erroneous since that option controls vhost-user frontends (previously known as "master") and not device backends (previously known as "slave").
