CMake: Bump cmake_minimum_required to 3.25 The SerenityOS platform files we upstreamed were first released in version 3.25.0
2022-12-10 20:40:24 +00:00
cmake_minimum_required(VERSION 3.25)
Meta: Add Meta/CMake to the CMAKE_MODULE_PATH for Serenity and Lagom This makes it so we don't need to specify the full path to all the helper scripts we include() from different places in the codebase and feels a lot cleaner.

cmake: Make setting CMAKE_BUILD_TYPE an error. I tried setting it to Release, then noticed that it didn't build due to gcc's optimizer-level dependent warnings and -Werror, then started fixing the warnings for a bit (all false positives), then looked at the global CMakeLists.txt and realized that the default build is aleady using compiler optimizations. It looks like people aren't supposed to change this, so make that explicit to be friendly to people familiar with cmake but new to serenity.

CMake: Fix message levels for error conditions during configuration Make messages which should be fatal, actually fail the build. - FATAL is not a valid mode keyword. The full list is available in the docs: https://cmake.org/cmake/help/v3.19/command/message.html - SEND_ERROR doesn't immediately stop processing, FATAL_ERROR does. We should immediately stop if the Toolchain is not present. - The app icon size validation was just a WARNING that is easy to overlook. We should promote it to a FATAL_ERROR so that people will not overlook the issue when adding a new application. We can only make the small icon message FATAL_ERROR, as there is currently one violation of the medium app icon validation.

Meta: Switch to a SuperBuild that splits host and target builds Replace the old logic where we would start with a host build, and swap all the CMake compiler and target variables underneath it to trick CMake into building for Serenity after we configured and built the Lagom code generators. The SuperBuild creates two ExternalProjects, one for Lagom and one for Serenity. The Serenity project depends on the install stage for the Lagom build. The SuperBuild also generates a CMakeToolchain file for the Serenity build to use that replaces the old toolchain file that was only used for Ports. To ensure that code generators are rebuilt when core libraries such as AK and LibCore are modified, developers will need to direct their manual `ninja` invocations to the SuperBuild's binary directory instead of the Serenity binary directory. This commit includes warning coalescing and option style cleanup for the affected CMakeLists in the Kernel, top level, and runtime support libraries. A large part of the cleanup is replacing USE_CLANG_TOOLCHAIN with the proper CMAKE_CXX_COMPILER_ID variable, which will no longer be confused by a host clang compiler.

Meta+CMake: Remove "image" ninja target in favor of "qemu-image" "image" was an alias for "qemu-image". I want to add an `image` userland utility, which clashes with that shortname. So remove the existing "image" target. It was just an alias for "qemu-image". If you use serenity.sh to build, nothing changes. This only affects you if you run ninja manually -- you now have to say `ninja qemu-image` to build the disk image.

The program uses whiptail(1) for user interaction.

CMake: Hide KMALLOC_VERIFY_NO_SPINLOCK_HELD so folks don't find it Since I introduced this functionality there has been a steady stream of people building with `ALL_THE_DEBUG_MACROS` and trying to boot the system, and immediately hitting this assert. I have no idea why people try to build with all the debugging enabled, but I'm tired of seeing the bug reports about asserts we know are going to happen at this point. So I'm hiding this value under the new ENABLE_ALL_DEBUG_FACILITIES flag instead. This is only set by CI, and hopefully no-one will try to build with this thing (It's documented as not recommended). Fixes: #7527

Kernel: Add option to build with coverage instrumentation and KCOV GCC and Clang allow us to inject a call to a function named __sanitizer_cov_trace_pc on every edge. This function has to be defined by us. By noting down the caller in that function we can trace the code we have encountered during execution. Such information is used by coverage guided fuzzers like AFL and LibFuzzer to determine if a new input resulted in a new code path. This makes fuzzing much more effective. Additionally this adds a basic KCOV implementation. KCOV is an API that allows user space to request the kernel to start collecting coverage information for a given user space thread. Furthermore KCOV then exposes the collected program counters to user space via a BlockDevice which can be mmaped from user space. This work is required to add effective support for fuzzing SerenityOS to the Syzkaller syscall fuzzer. :^) :^)

Meta+LibC: Don't allow text relocations in SerenityOS libraries The `-z,text` linker flag causes the linker to reject shared libraries and PIE executables that have textrels. Our code mostly did not use these except in one place in LibC, which is changed in this commit. This makes GNU ld match LLD's behavior, which has this option enabled by default. TEXTRELs pose a security risk, as performing these relocations require executable pages to be written to by the dynamic linker. This can significantly weaken W^X hardening mitigations. Note that after this change, TEXTRELs can still be used in ports, as the dynamic loader code is not changed. There are also uses of it in the kernel, removing which are outside the scope of this PR.

Meta: Do not allow undefined symbols in executables and shared objects The `--allow-shlib-undefined` option is a bit of a misnomer. It actually controls whether we should be allowed to have undefined references after symbols from all dependencies have been resolved, so it applies both to shared libraries and executables. LLD defaults to allowing undefined references in shared libraries, but not in executables. Previously, we had to disable this check for executables too, as it caused a build failure due to the LibC-LibPthread-libc++ and the LibCore-LibCrypto circular dependencies. Now that those have been resolved, we can enable this warning, in the hopes that it will prevent us from introducing circular libraries and missing dependencies that might cause unexpected breakage.

The legal aspects of redistributing this file as we currently do are not quite clear to me, they require either GPL (version 2 or later) or 3-clause BSD - Serenity is 2-clause BSD... The current version we use is 2019.08.08, so quite outdated - and while most of these devices are obviously not supported, we're still capable of *listing* them, so having an up-to-date version with recent additions and fixes would be nice. This updates the root CMakeLists.txt to check for existence of the file and download it if not found - effectively on every fresh build. Do note that this is not a critical file, and the system runs just fine should this ever fail. :^)

A component can have an optional description which isn't used by the build system but may be useful for a configuration UI. Components specify the TARGETS which should be built when the component is enabled. They can also specify other components which they depend on (with DEPENDS). This also adds the BUILD_EVERYTHING CMake variable which lets the user build all optional components. For now this defaults to ON to make the transition to the components-based build system easier. The list of components is exported as an INI file in the build directory (e.g. Build/i686/components.ini). Fixes #8048.

Meta: Download uncompressed files instead of *.gz Problem: cmake cannot handle gzip files (see https://gitlab.kitware.com/cmake/cmake/-/issues/23054 for more details). Instead of downloading the compressed (*.gz) USB and PCI ids, we not download the raw uncompressed files. The sizes we "loose" due to downloading such files are meaningless. This are the file sizes: ``` diego@debian:~/$ ls -lh pci.ids{,.gz} usb.ids{,.gz} -rw-r--r-- 1 diego diego 1.3M Aug 7 04:15 pci.ids -rw-r--r-- 1 diego diego 300K Aug 7 04:15 pci.ids.gz -rw-r--r-- 1 diego diego 700K May 20 22:34 usb.ids -rw-r--r-- 1 diego diego 245K May 20 22:34 usb.ids.gz ```

Build: Remove gzip -k usage in PCI/USB ID files and crypt for OpenBSD OpenBSD gzip does not have the -k flag to keep the original after extraction. Work around this by copying the original gzip to the dest and then extracting. A bit of a hack, but only needs to be done for the first-time or rebuilds OpenBSD provides crypt in libc, not libcrypt. Adjust if/else to check for either and proceed accordingly Remove outdated OpenBSD checks when building the toolchain

Base: Remove /res/pci.ids and download at build time instead This is an external file from https://pci-ids.ucw.cz that's being updated daily, which was imported a while ago but probably shouldn't live in the SerenityOS repository in the first place (or else would need manual maintenance). The legal aspects of redistributing this file as we currently do are not quite clear to me, they require either GPL (version 2 or later) or 3-clause BSD - Serenity is 2-clause BSD... The current version we use is 2019.08.08, so quite outdated - and while most of these devices are obviously not supported, we're still capable of *listing* them, so having an up-to-date version with recent additions and fixes would be nice. This updates the root CMakeLists.txt to check for existence of the file and download it if not found - effectively on every fresh build. Do note that this is not a critical file, and the system runs just fine should this ever fail. :^)
