a7b14306d5 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

608952ff71 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

Introduce "verbose" and "batch" modes 
Rewrite the way the output is processed:
- Define verbosity level (currently warn, info (default) & verbose)
- Add a batch mode, for simple machine parsing

RedHat uses a different configuration name 2018-01-08 12:59:12 +01:00
Vincent Brillault
66f7708095
Refactor RedHat support: 
- Isolate file check to different elif (allowing to add more)
- Do the PTI debugfs check first (faster and supposed to be dynamic)
- If pti_enable is 0, don't trust dmesg (supposed to be dynamic)

1aaca63dcf Improve "running as root" check 
Small issue with the USER environment variable:

  $ echo $USER
  thib
  $ sudo sh -c 'echo $USER'
  thib
  $ sudo -i sh -c 'echo $USER'
  root

Rather than recommending users to use sudo --login / -i, use the (very
widespread/portable) id program to retrieve the effective user ID
instead and don't change the recommendation.

  $ id -u
  1000
  $ sudo id -u
  0
  $ sudo -i id -u
  0
