Found and fixed: There was an imbalance in the syscall exit patch. It was using a fragile heuristic to guess if the slow-work path should be taken or not. That in combination with latest glibc using syscall probing (I had to switch to an Arch vm image) caused the audit path to be taken on entry but not on exit if a call was unsupported. A long pending issue in I-pipe. Patches for the various x86 branches will follow. Jan -- Siemens AG, T RDA IOT Corporate Competence Center Embedded Linux
