Subjectsigned exec, was: Re: When to submit something? and: signed executables.


Just a few questions for you:

1. How much slowes your module down the system?
2. You have kernel MD5ing a few megabyte executable. Are all processes
other stopped (kernel is not reentrant) during this?
3. Do you solve shared libraries modification?
4. Isn't "chattr +i" sufficient protection with much less impact on
performance?
