If you're on MIPS, x86 code and syscall numbers won't help you. In this case the proper syscall numbers are defined in arch/mips/include/uapi/asm/unistd.h. Additionally, note that your kernel version does not seem to implement the getrandom syscall for MIPS: $ git blame arch/mips/include/uapi/asm/unistd.h | grep getrandom 42944521 (Ralf Baechle 2014-08-26 03:03:40 +0200 376) #define __NR_getrandom (__NR_Linux + 353) 42944521 (Ralf Baechle 2014-08-26 03:03:40 +0200 716) #define __NR_getrandom (__NR_Linux + 313) 42944521 (Ralf Baechle 2014-08-26 03:03:40 +0200 1060) #define __NR_getrandom (__NR_Linux + 317) $ git show 42944521 | head -n 5 commit 42944521af97a3b25516f15f3149aec3779656dc Author: Ralf Baechle <[email protected]> Date: Tue Aug 26 03:03:40 2014 +0200 MIPS: Wire up new syscalls getrandom and memfd_create. $ git show v3.10.20 | head -n 3 tag v3.10.20 Tagger: Greg Kroah-Hartman <[email protected]> Date: Wed Nov 20 12:28:06 2013 -0800 Regards, Markus _______________________________________________ Kernelnewbies mailing list [email protected] http://lists.kernelnewbies.org/mailman/listinfo/kernelnewbies
