clang: Add status of CVE-2024-7883

2026-06-16T05:17:41+00:00

The patch (CVE-2024-7883.patch) is correctly applied via llvm-project-source's do_patch task. However, because common-source.inc sets SRC_URI = "" in the clang recipe (shared-source architecture), cve_check finds no patches in the clang recipe and reports the CVE as Unpatched. Add an explicit CVE_STATUS declaration to mark the CVE as fixed and document that the patch is applied via llvm-project-source, without altering the shared-source build flow.

clang.bbclass: Allow overriding LTO:toolchain-clang

2026-02-11T04:55:33+00:00

Currently, LTO:toolchain-clang is defined using the immediate assignment operator (=). This forces the variable to the default value defined in the class, preventing users from overriding LTO flags for the clang toolchain via distro configuration or local.conf. Change the assignment to use the conditional assignment operator (?=). This ensures that if LTO:toolchain-clang is already set (e.g., in a distro include file), the custom value is preserved and not overwritten by the default. Signed-off-by: mark.yang

clang.bbclass: add clang-native to BASE_DEFAULT_DEPS

2025-12-12T04:21:48+00:00

Add it for target builds in: BASE_DEFAULT_DEPS:append:class-target:toolchain-clang:class-target because ${MLPREFIX}clang-cross-${TARGET_ARCH} contains a broken symlink to clang binary provided by clang-native and then in case someone changes e.g. TC_CXX_RUNTIME = "llvm" to TC_CXX_RUNTIME:class-target = "llvm" then both clang-native and clang-cross-${TARGET_ARCH} are correctly rebuilt, but unfortunately the hashequiv output hash of clang-cross-${TARGET_ARCH} doesn't change (because the broken symlink is still the same), so e.g. gptfdisk which depends on "equivalent" clang-cross from BASE_DEFAULT_DEPS doesn't get rebuilt, but then it still links with libc++.so.1 while in clean build without sstate and hashequiv it will link with libstdc++.so.6 (because TC_CXX_RUNTIME affects only clang-native and the override for class-target doesn't work as one might expect). This might need some bigger changes in hashequiv to have special handlink of broken symlinks in the output, if the symlink target is provided by some dependency, we should include the hash of the symlink target to make sure the outhash changes even when something deeper in dependency tree changed the target binary (or error out when there is no direct dependency of the provider). clang-cross from oe-core master doesn't have this issue, because it contains the actual binary from clang-native after: https://github.com/openembedded/openembedded-core/commit/3b0128fe6421e64674fd250e0b4e6afb1c8ce436 so the outhash is changed when this binary is changed.

bpftrace 0.20.1: Fix CVE-2024-2313

2025-12-12T04:21:23+00:00

Upstream Repository: https://github.com/bpftrace/bpftrace.git Bug Details: https://nvd.nist.gov/vuln/detail/CVE-2024-2313 Type: Security Fix CVE: CVE-2024-2313 Score: 2.8 Patch: https://github.com/bpftrace/bpftrace/commit/bc73244963f2 Note: - This CVE was initially addressed via commit 4be4b7191acb [1], which added ownership verification for unpacked kernel headers. - The fix was deemed insufficient and a revised comprehensive fix was implemented in commit bc73244963f2 [2], which completely removes the risky functionality. - This patch applies only the revised fix (bc73244963f2) which supersedes the initial partial fix.

bpftool: Use gcc instead of clang compiler

2025-09-05T16:12:33+00:00

While compiling bpftool with clang, it fails with below error: | error: no member named 'id' in 'struct bpf_link' | return BPF_CORE_READ((struct bpf_link *)ent, id); bpftool is kernel tool to inspect and manipulate eBPF programs and maps. And kernel is built using GCC by default. Maintaining compatibility with Clang is an ongoing challenge, and using Clang solely for building bpftool is ineffective unless the entire kernel is compiled with Clang. Hence, updated TOOLCHAIN of bpftool to gcc. Signed-off-by: Deepak Rathore

perf: Use gcc as default compiler

2025-08-28T16:48:56+00:00

Since its being build from kernel sources which are procecced with gcc by default KERNEL_CC is gcc, its a constant battle to keep this compiling with clang, so unless clang is also used to compile kernel this is a fruitless excercise to use clang just for perf.
