2019-06-05Implement dumpability tracking and checksMichael Pratt
We don't actually support core dumps, but some applications want to get/set dumpability, which still has an effect in procfs. Lack of support for set-uid binaries or fs creds simplifies things a bit. As-is, processes started via CreateProcess (i.e., init and sentryctl exec) have normal dumpability. I'm a bit torn on whether sentryctl exec tasks should be dumpable, but at least since they have no parent normal UID/GID checks should protect them. PiperOrigin-RevId: 251712714
