   For reference, The clone3() system call first appeared in Linux 5.3.

   Concept ACK

   I think we need to #define __NR_clone3 (if not defined) like we do for statx and other relatively recently introduced syscalls:

   0// Define system call numbers for x86_64 that are referenced in the system call profile
   1// but not provided by the kernel headers used in the GUIX build.
   2#ifndef __NR_statx
   3#define __NR_statx 332
   4#endif

   How do I find the number?

   How do I find the number?

   Usually in /usr/include/x86_64-linux-gnu/asm/unistd_64.h for x86_64.

    Thanks again for testing on diverse systems and filling in the gaps!

    From the original syscall sandbox PR #20487 (comment): As have been noted in previous discussions above syscall sandboxing is a type of feature that needs experimentation and fine-tuning for different environments to catch potential diversity in syscall use across systems. Such experimentation was required when sandboxing using seccomp-bpf was introduced in projects such as Chromium, OpenSSH and Tor, and it will be required for Bitcoin Core too. There is really no way around it :)
