Hello List,
I thought about defending tor with ptrace().
For people, that cannot use yama sysctl, write
a knob tor_announce_ptrace_check()
Then, before tor_init() check with standard code
from silvio caesare example.
Later renew check in periodic_events or in event_loop.
The check must always fail, when uid less then 101.
This way, a user without root, can be informed, whether
the machine traces him.
Greetings
