parse_config error when searching for fs.suid_dumpable

[anniehedgpeth]

parse_config error

I wanted to use the parse_config resource instead of a file resource to match content for fs.suid_dumpable in /etc/systctl.conf. So I tried using

  describe parse_config('/etc/sysctl.conf') do
    its('fs.suid_dumpable') { should eq '0' }
  end

See:
https://github.com/anniehedgpeth/ubuntu-14-cis-profile/blob/master/controls/4.rb#L22

But it gets this error

  ✖  4.1: 4.1 Restrict Core Dumps (Scored) (1 failed)
     undefined method `suid_dumpable' for nil:NilClass

InSpec and Platform Version

InSpec version 0.28.1
MacOs 10.11.6

Replication Case

@anniehedgpeth You run into a specific issue :-)

# What should work, but isnt
options = {
  assignment_re: /^\s*([^=]*?)\s*=\s*(.*?)\s*$/
}

output = file('/etc/sysctl.conf', options).content
describe parse_config(output) do
 its('kernel.domainname') { should eq 'example.com' }
 its('fs.suid_dumpable') { should eq '0' }
end

also, the same should work with parse_config_file:

options = {
  assignment_re: /^\s*([^=]*?)\s*=\s*(.*?)\s*$/
}
describe parse_config_file('/etc/sysctl.conf', options) do
 its('kernel.domainname') { should eq 'example.com' }
 its('fs.suid_dumpable') { should eq '0' }
end

For now, we need to circumvent the issue #875 with the following code:

# What we need to do right now until # is fixed
describe parse_config_file('/etc/sysctl.conf', options).params['kernel.domainname'] do
 it { should eq 'example.com' }
end
describe parse_config_file('/etc/sysctl.conf', options).params['fs.suid_dumpable'] do
 it { should eq '0' }
end

This functionality has been added with #876.

@anniehedgpeth Also be aware the the regular expression you used was not working. I used:

options = {
  assignment_re: /^\s*([^=]*?)\s*=\s*(.*?)\s*$/
}

The RSpec issues is tracked in #875, improvements #876 for parse_config will be shipped with the next InSpec release.
