2023-01-26tests/tcg: Do not build/run TCG tests if TCG is disabledFabiano Rosas1-1/+5

2023-01-11configure: remove backwards-compatibility codePaolo Bonzini1-10/+0
The cmd_line.txt mangling is only needed when rebuilding from very old trees and is kept mostly as an example of how to extend it. However, Meson 0.63 introduces a deprecation mechanism for meson_options.txt that can be used instead, so get rid of our home-grown hack.

2023-01-11enforce use of G_GNUC_PRINTF attributesDaniel P. Berrangé1-0/+1
We've been very gradually adding G_GNUC_PRINTF annotations to functions over years. This has been useful in detecting certain malformed printf strings, or cases where we pass user data as the printf format which is a potential security flaw. Given the inherant memory corruption danger in use of format strings vs mis-matched variadic arguments, it is worth applying G_GNUC_PRINTF to all functions using printf, even if we know they are safe. The compilers can reasonably reliably identify such places with the -Wsuggest-attribute=format / -Wmissing-format-attribute flags. Signed-off-by: Daniel P.

2023-01-11configure: fix GLIB_VERSION for cross-compilationPaolo Bonzini1-1/+1
configure uses "pkg-config" directly so that GLIB_VERSION is always based on host glib version. To correctly handle cross-compilation it should use "$pkg_config" and take GLIB_VERSION from the cross-compiled glib.

2023-01-06configure: test all warningsPaolo Bonzini1-2/+5
Some warnings are hardcoded in QEMU_CFLAGS and not tested. There is no particular reason to single out these five, as many more -W flags are present on all the supported compilers. For homogeneity when moving the detection to meson, make them use the same warn_flags infrastructure.

2022-12-23configure: Fix check-tcg not executing any testsMukilan Thiyagarajan1-3/+1
After configuring with --target-list=hexagon-linux-user running `make check-tcg` just prints the following: ``` make: Nothing to be done for 'check-tcg' ``` In the probe_target_compiler function, the 'break' command is used incorrectly. There are no lexically enclosing loops associated with that break command which is an unspecfied behaviour in the POSIX standard. The dash shell implementation aborts the currently executing loop, in this case, causing the rest of the logic for the loop in line 2490 to be skipped, which means no Makefiles are generated for the tcg target tests.

2022-12-20qga-win: add logging to Windows event logAndrey Drobyshev1-0/+3
This commit allows QGA to write to Windows event log using Win32 API's ReportEvent() [1], much like syslog() under *nix guests. In order to generate log message definitions we use a very basic message text file [2], so that every QGA's message gets ID 1. The tools "windmc" and "windres" respectively are used to generate ".rc" file and COFF object file, and then the COFF file is linked into qemu-ga.exe.

2022-11-22Run docker probe only if docker or podman are availableStefan Weil1-1/+1
The docker probe uses "sudo -n" which can cause an e-mail with a security warning each time when configure is run. Therefore run docker probe only if either docker or podman are available. That avoids the problematic "sudo -n" on build environments which have neither docker nor podman installed.

2022-11-06Fix broken configure with -Wunused-parameterStefan Weil1-4/+4
The configure script fails because it tries to compile small C programs with a main function which is declared with arguments argc and argv although those arguments are unused. Running `configure -extra-cflags=-Wunused-parameter` triggers the problem. configure for a native build does abort but shows the error in config.log. A cross build configure for Windows with Debian stable aborts with an error. Avoiding unused arguments fixes this.

2022-10-18configure: Avoid using strings binaryMichal Privoznik1-17/+18
When determining the endiandness of the target architecture we're building for a small program is compiled, which in an obfuscated way declares two strings. Then, we look which string is in correct order (using strings binary) and deduct the endiandness. But using the strings binary is problematic, because it's part of toolchain (strings is just a symlink to x86_64-pc-linux-gnu-strings or llvm-strings). And when (cross-)compiling, it requires users to set the symlink to the correct toolchain. Fortunately, we have a better alternative anyways. We can mimic what compiler.h is already doing: comparing __BYTE_ORDER__ against values for little/big endiandness.

2022-09-26Remove the slirp submodule (i.e. compile only with an external libslirp)Thomas Huth1-24/+0
Since QEMU 7.1 we don't support Ubuntu 18.04 anymore, so the last big important Linux distro that did not have a pre-packaged libslirp has been dismissed. All other major distros seem to have a libslirp package in their distribution already - according to repology.org: Fedora 35: 4.6.1 CentOS 8 (RHEL-8): 4.4.0 Debian 11: 4.4.0 OpenSUSE Leap 15.3: 4.3.1 Ubuntu LTS 20.04: 4.1.0 FreeBSD Ports: 4.7.0 NetBSD pkgsrc: 4.7.0 Homebrew: 4.7.0 MSYS2 mingw: 4.7.0 The only one that was still missing a libslirp package is OpenBSD - but the next version (OpenBSD 7.2 which will be shipped in October) is going to include a libslirp package. Since QEMU 7.2 will be published after OpenBSD 7.2, we should be fine there, too. So there is no real urgent need for keeping the slirp submodule in the QEMU tree anymore. Thus let's drop the slirp submodule now and rely on the libslirp packages from the distributions instead.

2022-09-26configure: Add -Wno-gnu-variable-sized-type-not-at-endChenyi Qiang1-0/+1
A Linux headers update to v6.0-rc switches some definitions from GNU 'zero-length-array' extension to the C-standard-defined flexible array member. e.g. struct kvm_msrs { __u32 nmsrs; /* number of msrs in entries */ __u32 pad; - struct kvm_msr_entry entries[0]; + struct kvm_msr_entry entries[]; }; Those (unlike the GNU zero-length-array) have some extra restrictions like 'this must be put at the end of a struct', which clang build would complain about. e.g. the current code struct { struct kvm_msrs info; struct kvm_msr_entry entries[1]; } msr_data = { } generates the warning like: target/i386/kvm/kvm.c:2868:25: error: field 'info' with variable sized type 'struct kvm_msrs' not at the end of a struct or class is a GNU extension [-Werror,-Wgnu-variable-sized-type-not-at-end] struct kvm_msrs info; ^ In fact, the variable length 'entries[]' field in 'info' is zero-sized in GNU defined semantics, which can give predictable offset for 'entries[1]' in local msr_data. The local defined struct is just there to force a stack allocation large enough for 1 kvm_msr_entry, a clever trick but requires to turn off this clang warning. Suggested-by: Daniel P.

2022-09-22configure: Avoid use of 'local' as it is non-POSIXPeter Maydell1-4/+3
We use the non-POSIX 'local' keyword in just two places in configure; rewrite to avoid it. In do_compiler(), just drop the 'local' keyword. The variable 'compiler' is only used elsewhere in the do_compiler_werror() function, which already uses the variable as a normal non-local one. In probe_target_compiler(), $try and $t are both local; make them normal variables and use a more obviously distinct variable name for $t.

2022-09-22configure: Add missing quoting for some easy casesPeter Maydell1-32/+32
This commit adds quotes in some places which: * are spotted by shellcheck * are obviously incorrect * are easy to fix just by adding the quotes It doesn't attempt fix all of the places shellcheck finds errors, or even all the ones which are easy to fix. It's just a random sampling which is hopefully easy to review and which cuts down the size of the problem for next time somebody wants to try to look at shellcheck errors.

Shellcheck correctly reports that we set python_version and never use it. This is a leftover from commit f9332757898a7: we used to use python_version purely to as part of the summary information printed at the end of a configure run, and that commit changed to printing the information from meson (which looks up the python version itself).

probe_target_compiler returns nonempty $target_cc for installed toolchains and $container_cross_cc for container-based toolchains. In both cases however the flags (coming from $cross_cc_cflags_${target_arch}) must be in $target_cflags. Therefore, do not clear them prior to returning from probe_target_compiler.
