puppet-selinux

Overview

Transparently create SELinux modules based on AVC denial messages, to easily allow otherwise denied system operations, and set file and directory security contexts

• selinux : Main class which makes sure the basics are set up correctly.
• selinux::audit2allow : Definition for allowing based on avc denial messages.
• selinux::filecontext : Manage SELinux file context.
• selinux::dircontext : Manage SELinux file context recursively (directories).
• selinux::portcontext : Manage SELinux port context.

Note : For SELinux booleans, use the Puppet built-in selboolean type.

selinux

Main SELinux class to be included on all nodes. If SELinux isn't available, it does nothing anyway.

selinux::audit2allow

Local SELinux modules, created from avc denial messages to be allowed.

The SELinux modules created and loaded are automatically prefixed with "local" in order to never conflict with modules from the currently loaded policy. You can get a list of existing loaded modules with : semodule -l

Example :

selinux::audit2allow { 'mydaemon':
  source => "puppet:///modules/${module_name}/selinux/messages.mydaemon",
}

The content of the above files is based on kernel/audit avc denial messages, typically found in /var/log/audit/audit.log. See the included messages.nrpe file for an example.

When using it multiple times on a single node, the selinux::concat parameter can be switched to true in order to create a single SELinux module instead of one each time it is used. This speeds up Puppet runs a lot.

selinux::filecontext and selinux::dircontext

Change SELinux file security context persistently using semanage.

To see all existing default contexts for file path patterns :

semanage fcontext -l

To see only the custom ones not included in the base policy, set manually or by this module :

semanage fcontext -l -C

Example to set a new recursive file context entry (for a directory), which will run the 'semanage' and 'restorecon' tools to apply the SELinux Type to the specified path both persistently and immediately.

selinux::dircontext { '/data/www':
  seltype => 'httpd_sys_content_t',
}

To set the context for just a file, without recursing :

selinux::filecontext { '/srv/foo.txt':
  seltype => 'public_content_t',
}

To copy the context from another file, set 'copy' to true and 'seltype' to the source file or directory :

selinux::dircontext { '/export/home':
  seltype => '/home',
  copy    => true,
}

selinux::portcontext

Change SELinux port security context persistently using semanage.

The proto must be tcp or udp. Example :

selinux::portcontext { '12345':
  seltype => 'redis_port_t',
  proto   => 'tcp',
}
