We use LLVM in the builder image to compile our core_bpf probe.

llvm >= 20 is not working with the BTF relocation.

There are two concurrent work items:

• [done]#2690: update to the latest clang version and modify the probe to pass the verifier.
  •  The failure has been reproduced and is confirmed to be a 'complexity' issue.
  • A first round of probe fixes have been proposed, but recvfrom fails in the UDP tests
  • A supplementary fix has been designed for recvfrom.
  • Lowering the size of IOV solved most UDP issues. Disabling tests for the remaining kernels (Mostly RHEL : ROX-32092).
• [done] #2692: keep using clang19 update base images to centos stream10
  • Requires to update ubi to version 10 as well, to get compatible libc
  • The base image comes with the newer GCC14
  • Requires to update TBB (third party dep) : new compiler throws a warning + -Werror. This warning was fixed last september, and the project does not make stable releases => update to master
  • Running the image against e2e tests in stackrox/stackrox gives a "all green" result.
  • => merged in master
