NAME
       dcc_client_selinux  - Security Enhanced Linux Policy for the dcc_client
       processes

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

       The  dcc_client	processes  execute with the dcc_client_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 dcc_client_t

ENTRYPOINTS
       The  dcc_client_t SELinux type can be entered via the dcc_client_exec_t
       file type.

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

       /usr/bin/dccproc

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
       dcc_client  policy  is  very  flexible  allowing	 users	to setup their
       dcc_client processes in as secure a method as possible.

       The following process types are defined for dcc_client:

       dcc_client_t

       Note: semanage permissive -a dcc_client_t  can  be  used	 to  make  the
       process	type  dcc_client_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.
       dcc_client policy is extremely flexible and has several	booleans  that
       allow you to manipulate the policy and run dcc_client 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 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 dcc_client_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
       dcc_client_t, you must turn on the kerberos_enabled boolean.

       setsebool -P kerberos_enabled 1

MANAGED FILES
       The SELinux process type dcc_client_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.

       dcc_client_map_t

	    /etc/dcc/map
	    /var/dcc/map
	    /var/lib/dcc/map
	    /var/run/dcc/map

       dcc_client_tmp_t

       dcc_var_t

	    /etc/dcc(/.*)?
	    /var/dcc(/.*)?
	    /var/lib/dcc(/.*)?

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	dcc_client  policy  is	very  flexible allowing users to setup
       their dcc_client processes in as secure a method as possible.

       STANDARD FILE CONTEXT

       SELinux defines the file context	 types	for  the  dcc_client,  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  dcc_client_exec_t	 '/srv/dcc_client/con‐
       tent(/.*)?'
       restorecon -R -v /srv/mydcc_client_content

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

       The following file types are defined for dcc_client:

       dcc_client_exec_t

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

       dcc_client_map_t

       - Set files with the dcc_client_map_t type, if you want	to  treat  the
       files as dcc client map data.

       Paths:
	    /etc/dcc/map, /var/dcc/map, /var/lib/dcc/map, /var/run/dcc/map

       dcc_client_tmp_t

       -  Set  files  with the dcc_client_tmp_t type, if you want to store dcc
       client temporary files in the /tmp directories.

       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 boolean can also be used to manipulate the booleans

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