make snap usable by operator? #120

Open se6astian-pi opened 4 years ago

with /dev/mem you have access to basically everything, so allowing that for non-root would basically make every user root probably make the cmv_snap3 suid? Sebastian tried the suid approach and it works

seems reasonable :)

anuejn commented 4 years ago

some scripts need that too but scripts cant be setuided so we probably need a more generalized approach

I tried the suid approach and the execution worked but the resulting images where just appearing to be random data. I also tried the static binary of cmv_snap3 from the old firmware on the new firmware and that worked in the end.

Its well possible I made a mistake somewhere along the way so please test.
