We use kernel 3.7 Fedora16, 64-bit and want to intercept kernel functions.

We tried Linux Kernel: System call hooking example and successfully received the address of "sys_call_table", while returned address of "access_remote_vm" is NULL.

Please advice.

  • There are many questions on Stack Overflow about replacing system calls in Linux kernel. Did you check them? – Tsyvarev Sep 22 '16 at 08:34
  • Yes we checked and didn't succeeded in latest kernels. – Pavel Komarov Sep 25 '16 at 05:50
  • Do you really need the function `access_remote_vm`? While it is strange that the function is absent on x86_64 with MMU support... BTW, kernel 3.7 is not a "latest kernel", it differs slightly from 3.4 on which answer, referenced by you, is based. – Tsyvarev Sep 25 '16 at 12:47
