2) Adding a LSM hook
We are doing both the command line and kernel version measurement in IMA.
Can you please elaborate on how this can be used outside of the scenario?
That will help me come back with a better design and code. I am
neutral about this.
As I said previously, initially you might want to only measure the
kexec boot command line, but will you ever want to verify or audit log
the boot command line hash?????Perhaps LSMs would be interested in the
boot command line. ??Should this be an LSM hook?
From an LSM perspective, is there any interest in the boot command line?

I can imagine an LSM that cares about the command line,
but I don't have interest in it for any work I have in progress.
