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

2018-12-05Check for CAP_SYS_RESOURCE in prctl(PR_SET_MM, ...)Zach Koopmans
If sys_prctl is called with PR_SET_MM without CAP_SYS_RESOURCE, the syscall should return failure with errno set to EPERM. See: http://man7.org/linux/man-pages/man2/prctl.2.html PiperOrigin-RevId: 224182874 Change-Id: I630d1dd44af8b444dd16e8e58a0764a0cf1ad9a3
2018-10-20Add more unimplemented syscall eventsFabricio Voznika
Added events for *ctl syscalls that may have multiple different commands. For runsc, each syscall event is only logged once. For *ctl syscalls, use the cmd as identifier, not only the syscall number. PiperOrigin-RevId: 218015941 Change-Id: Ie3c19131ae36124861e9b492a7dbe1765d9e5e59
