I recently setup my Puppetmaster server to run through Passenger via Apache instead of on the default webrick web server. SELinux made that not work and I've found some documentation on making rules to allow it however mine won't load. This is the policy I found via this website, http://sandcat.nl/~stijn/2012/01/20/selinux-passenger-and-puppet-oh-my/comme... .
module puppet_passenger 1.7;
require { type bin_t; type devpts_t; type httpd_t; type passenger_t; type port_t; type proc_net_t;
class process { getattr siginh setexec sigchld noatsecure transition rlimitinh }; class unix_stream_socket { getattr accept read write }; class capability { sys_resource sys_ptrace }; class file { entrypoint open create relabelfrom relabelto getattr setattr read write append ioctl lock rename link unlink }; class lnk_file { getattr read }; class udp_socket name_bind; class dir { getattr setattr add_name remove_name search open read write ioctl lock }; }
#============= httpd_t ============== allow httpd_t port_t:udp_socket name_bind;
allow httpd_t proc_net_t:file { read getattr open };
allow httpd_t bin_t:file entrypoint;
allow httpd_t passenger_t:process sigchld; allow httpd_t passenger_t:unix_stream_socket { getattr accept read write };
optional_policy(` puppet_manage_lib(httpd_t) puppet_search_log(httpd_t) puppet_search_pid(httpd_t) allow httpd_t puppet_var_lib_t:file { relabelfrom relabelto }; ')
#============= passenger_t ============== allow passenger_t devpts_t:dir search; allow passenger_t httpd_t:process { siginh rlimitinh transition noatsecure }; allow passenger_t self:capability { sys_resource sys_ptrace }; allow passenger_t self:process setexec;
ps_process_pattern(passenger_t, httpd_t) domain_read_all_domains_state(passenger_t)
Using the SELinux Make file works but when I try to add the new policy via "semodule -i puppet_passenger.pp" I get the following # semodule -i puppet_passenger.pp libsepol.print_missing_requirements: puppet_passenger's global requirements were not met: type/attribute passenger_t (No such file or directory). libsemanage.semanage_link_sandbox: Link packages failed (No such file or directory). semodule: Failed!
The blog I got the policy from mentioned disabling the rubygem_passenger policy, is that where passenger_t is defined? I've looked at the source of selinux-policy and see the required type of passenger_t is working so unsure why it doesn't work in my policy.
The policy from audit2allow generates this when using "grep -e 'httpd|passenger'" but it seems like too much allowance

Here's my version of selinux-policy
selinux-policy.noarch 3.7.19-126.el6_2.10 selinux-policy-targeted.noarch 3.7.19-126.el6_2.10
Any advice or pointers of how to get puppetmasterd to run through passenger WITH SELinux would be great.
Thanks - Trey
