seccomp: allow rseq syscall Starting with v4.18, the Linux kernel provides the rseq syscall which is a mechanism for fast userspace task synchronization. Starting with v2.35 glibc uses the new syscall, if it exists, to gain some performance improvements, so we need to update the policy files to allow it. Even on older kernels where rseq is not supported, glibc will still probe for its existence by expecting an -ENOSYS response.
