allowlist trap
# 'allowlist' would normally mean kill a task doing any syscall which is not
# allowlisted below. By appending 'trap' to the line, we will cause a SIGSYS
# to be sent to the task instead. 'errno 0' would mean don't allow the system
# call but immediately return 0. 'errno 22' would mean return EINVAL immediately.

# Since we are listing system calls by name, we can also ask to have them resolved
# for another arch, i.e. for 32/64-bit versions.
