Bug #: 15016
Summary: SystemTap + Probing User Space
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: uprobes
AssignedTo: systemtap@sourceware.org
ReportedBy: eldereng@hotmail.com
Classification: Unclassified
I use OpenSuSe 12.2 with XEN hypervisor. Studying the Systemtap (Chapter 4.
User-Space Probing), I saw that it is possible to do probing for applications
in user space, but it's not work in my kernel.
Running the command below, everything works correctly.
stap -v -e 'probe vfs.read {printf("read performed\n"); exit()}'
Pass 1: parsed user script and 90 library script(s) using
80812virt/24360res/2512shr/22300data kb, in 130usr/10sys/151real ms.
Pass 2: analyzed script: 1 probe(s), 1 function(s), 3 embed(s), 0 global(s)
using 300208virt/126464res/8372shr/115764data kb, in 1360usr/730sys/2131real

Pass 5: starting run.
read performed
Pass 5: run completed in 10usr/50sys/403real ms.
But, running the command below, nothing works.
stap -e 'probe process("/lib64/libc-2.15.so").function("malloc")
{println("test")}'
user-space facilities not available without kernel CONFIG_UTRACE or
CONFIG_TRACEPOINTS/CONFIG_ARCH_SUPPORTS_UPROBES/CONFIG_UPROBES
Pass 4: compilation failed. Try again with another '--vp 0001' option.
Can someone help me?

CONFIG_UPROBES-related code was merged into the Linus kernel only for version
3.5, so your 3.4.11 may simply be too old.

I installed the latest version of kernel (3.7.2), but the systemtap not working
for probing in user space.
I tested using the following command:
stap -vvv -e 'probe process("/bin/ls").function("*") { log(pp()) }' -c /bin/ls

SystemTap needs debug information to locate functions in your binary, which you
can install with your distro's package management. I'm not sure for openSUSE,
but in Fedora the package for /usr/bin/ls would be coreutils-debuginfo.
Note also, the version of the debuginfo package must exactly match the version
of the package which provided /usr/bin/ls.

Correct Josh, but if I build my code with debug it should work right?
In my case, this did not work. Look:
My code is (Command for compile is: gcc -g -o Application Application.c):
#include <stdlib.h>
#include <stdio.h>
#include <unistd.h>
#include <time.h>
int TimeForSleep();
int TimeForSleep(){
double nr=3.0;
return 1000000 * nr;
}
int main(int argc,char *argv[]){
while(1){
printf("test \n");
usleep(TimeForSleep());
}
return 0;
}
My script of systemtap:
probe process("/home/elder/Application").function("TimeForSleep").call
{
printf("found\n");
}
probe begin {
printf("INI\n");
}
probe end {
printf("FIM \n");
}
Return of systemtap:
