Description Josh Stone 2011-06-21 17:43:27 UTC 
A simple process probe aliased in stap itself:
> $ stap -l 'stap.system'
> stap.system

It ought to be allowed to unprivileged users too, but this fails:
> $ stap -l 'stap.system' --unprivileged
> $ echo $?
> 1

Manually specifying the probepoint works:
> $ stap -l 'process("stap").mark("stap_system__start")' --unprivileged
> process("stap").mark("stap_system__start")

So it seems that the alias breaks unprivileged access.
