Hi everyone, You might have noticed that the linux-leaks and linux-asan-ubsan jobs in GitHub Actions started failing last week. I investigated this so I'm sharing my findinds in case it helps. The failures are due to the new ubuntu-22.04 GitHub Actions image (release 20240310.1.0, [1]) which uses a kernel where ASLR is configured in a way that is incompatible with ASan and LSan as used in the GCC and Clang versions in that image. More info can be found in [2] and [3] and pages linked there. A workaround was already implemented in the image generation process [4], so the next version of the image should work. I think the images are released weekly. We could maybe add the same sysctl command to reduce the entropy to our YAML file, or we could live with it for the next week or so while waiting for the next image to roll out. Cheers, Philippe.
