minor is_cpu_vulnerable() changes ( #71 )
...
* correct is_cpu_vulnerable() comment
As far as I can tell, the function and usage are correct for the comment
to be inverted.
Add a clarifying note as to why the value choice makes sense.
* exit on invalid varient
If this happens, it's a bug in the script. None of the calling code
checks for status 255, so don't let a scripting bug cause a false
negative.
* no need to set vulnerable CPUs
According to comment above this code:
'by default, everything is vulnerable, we work in a "whitelist" logic here.'

fix(opcodes): fix regression introduced in previous commit

We were saying unknown instead of vulnerable when the count of lfence opcodes was low
This was not impacting batch mode or the final decision, just the human-readable output of the script.

With --batch json there must not be any other output on stdout, so redirect warnings to stderr will show the warning on the console and only the json output is on stdout.

Improve PTI detection even more
...
when PTI detection relies on dmesg, dmesg output is checked first
then /var/log/dmesg if dmesg output lacks boot time messages

Improve PTI detection
...
In case of a busy or misconfigured server, kernel message buffer loop
can be filled with messages broadcasted later than boot time. So dmesg
command wont return boot time messages.
Grepping /var/log/dmesg fixes it and this log file location semms pretty
standard across many common distros
