NAME
       certmaster_selinux  - Security Enhanced Linux Policy for the certmaster
       processes

DESCRIPTION
       Security-Enhanced Linux secures the certmaster processes	 via  flexible
       mandatory access control.

       The  certmaster	processes  execute with the certmaster_t SELinux type.
       You can check if you have these processes running by executing  the  ps
       command with the -Z qualifier.

       For example:

       ps -eZ | grep certmaster_t

ENTRYPOINTS
       The  certmaster_t SELinux type can be entered via the certmaster_exec_t
       file type.

       The default entrypoint paths for the certmaster_t domain are  the  fol‐
       lowing:

       /usr/bin/certmaster

PROCESS TYPES
       SELinux defines process types (domains) for each process running on the
       system

       You can see the context of a process using the -Z option to ps

       Policy governs the access confined processes have  to  files.   SELinux
       certmaster  policy is very flexible allowing users to setup their cert‐
       master processes in as secure a method as possible.

       The following process types are defined for certmaster:

       certmaster_t

       Note: semanage permissive -a certmaster_t  can  be  used	 to  make  the
       process	type  certmaster_t permissive. SELinux does not deny access to
       permissive process types, but the AVC (SELinux  denials)	 messages  are
       still generated.

BOOLEANS
       SELinux	policy	is customizable based on least access required.	 cert‐
       master policy is extremely flexible and has several booleans that allow
       you  to	manipulate  the	 policy	 and  run certmaster with the tightest
       access possible.

       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
       gin_nsswitch_use_ldap boolean. Disabled by default.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow all daemons to write corefiles to /, you must turn
       on the daemons_dump_core boolean. Disabled by default.

       setsebool -P daemons_dump_core 1

       If  you	want  to enable cluster mode for daemons, you must turn on the
       daemons_enable_cluster_mode boolean. Enabled by default.

       setsebool -P daemons_enable_cluster_mode 1

       If you want to allow all daemons to use tcp wrappers, you must turn  on
       the daemons_use_tcp_wrapper boolean. Disabled by default.

       setsebool -P daemons_use_tcp_wrapper 1

       If  you	want to allow all daemons the ability to read/write terminals,
       you must turn on the daemons_use_tty boolean. Disabled by default.

       setsebool -P daemons_use_tty 1

       If you want to deny any process from ptracing or	 debugging  any	 other
       processes,  you	must  turn  on	the  deny_ptrace  boolean.  Enabled by
       default.

       setsebool -P deny_ptrace 1

       If you want to allow all domains to use other domains file descriptors,
       you must turn on the domain_fd_use boolean. Enabled by default.

       setsebool -P domain_fd_use 1

       If  you	want to allow all domains to have the kernel load modules, you
       must  turn  on  the  domain_kernel_load_modules	boolean.  Disabled  by
       default.

       setsebool -P domain_kernel_load_modules 1

       If you want to allow all domains to execute in fips_mode, you must turn
       on the fips_mode boolean. Enabled by default.

       setsebool -P fips_mode 1

       If you want to enable reading of urandom for all domains, you must turn
       on the global_ssp boolean. Disabled by default.

       setsebool -P global_ssp 1

       If  you	want  to allow confined applications to run with kerberos, you
       must turn on the kerberos_enabled boolean. Enabled by default.

       setsebool -P kerberos_enabled 1

       If you want to allow system to run with	NIS,  you  must	 turn  on  the
       nis_enabled boolean. Disabled by default.

       setsebool -P nis_enabled 1

       If  you	want to allow confined applications to use nscd shared memory,
       you must turn on the nscd_use_shm boolean. Disabled by default.

       setsebool -P nscd_use_shm 1

NSSWITCH DOMAIN
       If you want to allow users to resolve user passwd entries directly from
       ldap  rather  then  using  a sssd server for the certmaster_t, you must
       turn on the authlogin_nsswitch_use_ldap boolean.

       setsebool -P authlogin_nsswitch_use_ldap 1

       If you want to allow confined applications to run with kerberos for the
       certmaster_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

PORT TYPES
       SELinux defines port types to represent TCP and UDP ports.

       You  can	 see  the  types associated with a port by using the following
       command:

       semanage port -l

       Policy governs the access  confined  processes  have  to	 these	ports.
       SELinux	certmaster  policy  is	very  flexible allowing users to setup
       their certmaster processes in as secure a method as possible.

       The following port types are defined for certmaster:

       certmaster_port_t

       Default Defined Ports:
		 tcp 51235

MANAGED FILES
       The SELinux process type certmaster_t can manage files labeled with the
       following file types.  The paths listed are the default paths for these
       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS
       SELinux requires files to have an extended attribute to define the file
       type.

       You can see the context of a file using the -Z option to ls

       Policy  governs	the  access  confined  processes  have to these files.
       SELinux certmaster policy is very  flexible  allowing  users  to	 setup
       their certmaster processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines	 the  file  context  types  for the certmaster, if you
       wanted to store files with these types in a diffent paths, you need  to
       execute	the  semanage  command to sepecify alternate labeling and then
       use restorecon to put the labels on disk.

       semanage	 fcontext  -a  -t  certmaster_etc_rw_t	 '/srv/certmaster/con‐
       tent(/.*)?'
       restorecon -R -v /srv/mycertmaster_content

       Note:  SELinux  often  uses  regular expressions to specify labels that
       match multiple files.

       The following file types are defined for certmaster:

       certmaster_etc_rw_t

       - Set files with the certmaster_etc_rw_t type, if you want to treat the
       files as certmaster etc read/write content.

       certmaster_exec_t

       -  Set files with the certmaster_exec_t type, if you want to transition
       an executable to the certmaster_t domain.

       certmaster_initrc_exec_t

       - Set files with the certmaster_initrc_exec_t  type,  if	 you  want  to
       transition an executable to the certmaster_initrc_t domain.

       certmaster_var_lib_t

       -  Set  files  with the certmaster_var_lib_t type, if you want to store
       the certmaster files under the /var/lib directory.

       certmaster_var_log_t

       - Set files with the certmaster_var_log_t type, if you  want  to	 treat
       the  data as certmaster var log data, usually stored under the /var/log
       directory.

       certmaster_var_run_t

       - Set files with the certmaster_var_run_t type, if you  want  to	 store
       the certmaster files under the /run or /var/run directory.

       Note:  File context can be temporarily modified with the chcon command.
       If you want to permanently change the file context you need to use  the
       semanage fcontext command.  This will modify the SELinux labeling data‐
       base.  You will need to use restorecon to apply the labels.

COMMANDS
       semanage fcontext can also be used to manipulate default	 file  context
       mappings.

       semanage	 permissive  can  also	be used to manipulate whether or not a
       process type is permissive.

       semanage module can also be used to enable/disable/install/remove  pol‐
       icy modules.

       semanage port can also be used to manipulate the port definitions

       semanage boolean can also be used to manipulate the booleans

       system-config-selinux is a GUI tool available to customize SELinux pol‐
       icy settings.
