dccm_selinux(8)		      SELinux Policy dccm	       dccm_selinux(8)

NAME
       dccm_selinux - Security Enhanced Linux Policy for the dccm processes

DESCRIPTION
       Security-Enhanced  Linux secures the dccm processes via flexible manda‐
       tory access control.

       The dccm processes execute with the dccm_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 dccm_t

ENTRYPOINTS
       The dccm_t SELinux type can be entered via the dccm_exec_t file type.

       The default entrypoint paths for the dccm_t domain are the following:

       /usr/sbin/dccm, /usr/libexec/dcc/dccm

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
       dccm policy is very flexible allowing users to setup  their  dccm  pro‐
       cesses in as secure a method as possible.

       The following process types are defined for dccm:

       dccm_t

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

BOOLEANS
       SELinux policy is customizable based on least  access  required.	  dccm
       policy is extremely flexible and has several booleans that allow you to
       manipulate the policy and run dccm 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 dccm_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
       dccm_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 dccm policy is very flexible allowing users to setup their dccm
       processes in as secure a method as possible.

       The following port types are defined for dccm:

       dccm_port_t

       Default Defined Ports:
		 tcp 5679
		 udp 5679

MANAGED FILES
       The SELinux process type dccm_t can manage files labeled with the  fol‐
       lowing  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 dccm policy is very flexible allowing users to setup their dccm
       processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux	defines	 the file context types for the dccm, 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 dccm_exec_t '/srv/dccm/content(/.*)?'
       restorecon -R -v /srv/mydccm_content

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

       The following file types are defined for dccm:

       dccm_exec_t

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

       Paths:
	    /usr/sbin/dccm, /usr/libexec/dcc/dccm

       dccm_tmp_t

       - Set files with the dccm_tmp_t type, if you want to store dccm	tempo‐
       rary files in the /tmp directories.

       dccm_var_run_t

       - Set files with the dccm_var_run_t type, if you want to store the dccm
       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.
