Public bug reported:
Systemtap will not run even basic scripts. I figured out why, it is
because Ubuntu's systemtap is heavily out of date.
When I try this simple script:
---------------------------------------
#! /usr/bin/env stap
probe oneshot { println("hello world") }
---------------------------------------
It produces errors like this:
---------------------------------------
In file included from /usr/share/systemtap/runtime/linux/runtime.h:204:0,
from /usr/share/systemtap/runtime/runtime.h:24,
from
/tmp/stapU8dHoL/stap_51a003b6f4617d04704c8d0c0008dd2c_967_src.c:25:
/usr/share/systemtap/runtime/linux/access_process_vm.h: In function
‘__access_process_vm_’:
/usr/share/systemtap/runtime/linux/access_process_vm.h:35:29: error: passing
argument 1 of ‘get_user_pages’ makes integer from pointer without a cast
[-Werror=int-conversion]
ret = get_user_pages (tsk, mm, addr, 1, write, 1, &page, &vma);
---------------------------------------
Systemtap is attempting to compile generated C code against the kernel
headers. The function get_user_pages() as changed since systemtap worked
on Ubuntu. It is using the following prototype for get_user_pages:
long get_user_pages(struct task_struct *tsk, struct mm_struct *mm,
unsigned long start, unsigned long nr_pages,
int write, int force, struct page **pages,
struct vm_area_struct **vmas);
For my kernel (4.10.0-35-generic), this is the function prototype:
long get_user_pages(unsigned long start, unsigned long nr_pages,
unsigned int gup_flags, struct page **pages,
struct vm_area_struct **vmas);
This results in even simple systemtap scripts failing to compile. The
solution is to update the systemtap package for Ubuntu.
I am on Ubuntu 16.04, using the 4.10.0-35-generic kernel.
