2019-09-24gvisor: change syscall.RawSyscall to syscall.RawSyscall6 where requiredgVisor bot
Before https://golang.org/cl/173160 syscall.RawSyscall would zero out the last three register arguments to the system call. That no longer happens. For system calls that take more than three arguments, use RawSyscall6 to ensure that we pass zero, not random data, for the additional arguments. PiperOrigin-RevId: 271062527

2018-11-20Use RET_KILL_PROCESS if available in kernelFabricio Voznika
RET_KILL_THREAD doesn't work well for Go because it will kill only the offending thread and leave the process hanging. RET_TRAP can be masked out and it's not guaranteed to kill the process. RET_KILL_PROCESS is available since 4.14. For older kernel, continue to use RET_TRAP as this is the best option (likely to kill process, easy to debug).

2018-10-10Add seccomp filter configuration to ptrace stubs.Adin Scannell
This is a defense-in-depth measure. If the sentry is compromised, this prevents system call injection to the stubs. There is some complexity with respect to ptrace and seccomp interactions, so this protection is not really available for kernel versions < 4.8; this is detected dynamically. Note that this also solves the vsyscall emulation issue by adding in appropriate trapping for those system calls. It does mean that a compromised sentry could theoretically inject these into the stub (ignoring the trap and resume, thereby allowing execution), but they are harmless.
