View custom selinux policies

Solution 1:

This answer is borrowed from this question. While it doesn't exactly answer the question of seeing all custom SELinux policies applied to the machine, it does provide the set of tools you would want to use to see any custom policies or narrow it down a fair bit.

Some of the commands to obtain this info are (examples use httpd_log_t):

1. seinfo

   # seinfo -x --type=httpd_log_t /etc/selinux/default/policy/policy.26
      httpd_log_t
         file_type
         non_security_file_type
         logfile
   

2. sesearch

   # sesearch --dontaudit -t httpd_log_t /etc/selinux/default/policy/policy.26 | head
   Found 35 semantic av rules:
       dontaudit run_init_t file_type : dir { getattr search open } ;
       dontaudit staff_t non_security_file_type : file getattr ;
       dontaudit staff_t non_security_file_type : dir { ioctl read getattr lock search open } ;
       dontaudit staff_t non_security_file_type : lnk_file getattr ;
       dontaudit staff_t non_security_file_type : sock_file getattr ;
       dontaudit staff_t non_security_file_type : fifo_file getattr ;
       dontaudit unconfined_t non_security_file_type : file getattr ;
       dontaudit unconfined_t non_security_file_type : dir { ioctl read getattr lock search open } ;
       dontaudit unconfined_t non_security_file_type : lnk_file getattr ;
   

3. semanage

   # semanage fcontext -l | grep httpd_log_t
   /etc/httpd/logs                                    all files          system_u:object_r:httpd_log_t:s0
   /var/log/apache(2)?(/.*)?                          all files          system_u:object_r:httpd_log_t:s0
   /var/log/apache-ssl(2)?(/.*)?                      all files          system_u:object_r:httpd_log_t:s0
   /var/log/cacti(/.*)?                               all files          system_u:object_r:httpd_log_t:s0
   /var/log/cgiwrap\.log.*                            regular file       system_u:object_r:httpd_log_t:s0
   /var/log/horde2(/.*)?                              all files          system_u:object_r:httpd_log_t:s0
   /var/log/httpd(/.*)?                               all files          system_u:object_r:httpd_log_t:s0
   /var/log/lighttpd(/.*)?                            all files          system_u:object_r:httpd_log_t:s0
   /var/log/piranha(/.*)?                             all files          system_u:object_r:httpd_log_t:s0
   /var/www(/.*)?/logs(/.*)?                          all files          system_u:object_r:httpd_log_t:s0

Solution 2:

As of RHEL 7:

 semanage export 

should export all local configuration changes.
