When attempting to perform the clone syscall, an error of -1 is returned where I would expect it to succeed. Running the same executable outside of qemu works as expected. +Steps to reproduce: +1. gcc clone.c +2. qemu-x86_64 a.out +Additional information: +I've tried building with gcc, zig cc, and clang and the output of each works fine when running natively, but running under qemu fails. I originally discovered it when cross compiling to riscv64 but it doesn't seem to be limited to that architecture. + +``` +// clone.c + +#include <linux/sched.h> +#include <sched.h> +#include <sys/syscall.h> +#include <unistd.h> +#include <stdio.h> + +int main(void) { + + long pid = syscall( SYS_clone, 0, 0, 0, 0, 0 ); + + if (pid < 0) { + printf( "error %ld\n", pid ); + } else if (pid == 0) { + printf( "child %ld\n", pid ); + } else { + printf( "parent %ld\n", pid ); + } + + return 0; +} +``` |
