How can I query for all selinux rules/default file contexts/etc affecting a type

Solution 1:

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
