Regex problem with an SELinux context type with a dash

I have a file on the system with the following SELinux context

[root@sut ~]# matchpathcon /etc/my-app/my-config.cfg

/etc/my-app/my-config.cfg    system_u:object_r:my-app_config_t:s0

I also have a File["/etc/my-app/my-config.cfg"] resource defined in my manifests, which doesn't call out the seltype attribute, so according the documentation , it should get the type from matchpathcon, and set it to "my-app_config_t".

However, it's setting it to "my" instead.

Oct 16 13:13:43 src@sut puppet-agent[902]: (/File[/etc/my-app/my-config/cfg]/seltype) seltype changed 'etc_t' to 'my'

I think I've tracked this down to the regex in parse_selinux_context() in utils/selinux.rb, where the 'type' section of the regexp stops accepting characters at the dash in the "my-app_config_t"

I think it would be better if the regexp were something more lenient , like

/^([^:]+):([^:]+):([^:]+)(?::([a-zA-Z0-9:,._-]+))?/
