Perf data leaking kernel file offsets |
||||||||||||||||||||
Issue descriptionWe noticed non-zero kernel file offsets in perf data reports received by CWP starting with build 10516.0.0, see b/77610802. This was diagnosed to quipper failing to apply the right remapping to the kernel mmap after the perf uprev to 4.14. Fix is being submitted upstream. Need to sync the quipper version used by Chrome OS on branch 67.
