2021-03-29[syserror] Split usermem packageZach Koopmans
Split usermem package to help remove syserror dependency in go_marshal. New hostarch package contains code not dependent on syserror. PiperOrigin-RevId: 365651233
2021-01-12Fix simple mistakes identified by goreportcard.Adin Scannell
These are primarily simplification and lint mistakes. However, minor fixes are also included and tests added where appropriate. PiperOrigin-RevId: 351425971

2020-09-15Add support for OCI seccomp filters in the sandbox.Ian Lewis
OCI configuration includes support for specifying seccomp filters. In runc, these filter configurations are converted into seccomp BPF programs and loaded into the kernel via libseccomp. runsc needs to be a static binary so, for runsc, we cannot rely on a C library and need to implement the functionality in Go. The generator added here implements basic support for taking OCI seccomp configuration and converting it into a seccomp BPF program with the same behavior as a program generated by libseccomp. - New conditional operations were added to pkg/seccomp to support operations available in OCI. - AllowAny and AllowValue were renamed to MatchAny and EqualTo to better reflect that syscalls matching the conditionals result in the provided action not simply SCMP_RET_ALLOW. - BuildProgram in pkg/seccomp no longer panics if provided an empty list of rules. It now builds a program with the architecture sanity check only. - ProgramBuilder now allows adding labels that are unused. However, backwards jumps are still not permitted.

2020-08-12enable seccomp test on arm64Howard Zhang
syscalls in ARM64 is different from that in X86_64, use differen syscallrules for each arch. The auditnumber are also different for different arch. Use LINUX_AUDIT_ARCH to get correct auditnumber. Signed-off-by: Howard Zhang <howard.zhang@arm.com>

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.
