Revision 6b1873371cea13036171d03a7c1e3e59158b4505 authored by Richard Weinberger on 09 August 2015, 19:49:07 UTC, committed by Richard Weinberger on 19 October 2015, 20:53:37 UTC
If UML is executing a helper program it is using waitpid() with the __WCLONE flag to wait for the program as the helper is executed from a clone()'ed thread. While using __WCLONE is perfectly fine for clone()'ed childs it won't detect terminated childs if the helper has issued an execve(). We have to use __WALL to wait for both clone()'ed and regular childs to detect the termination before and after an execve().
