dcc_selinux(8) dcc SELinux Policy documentation dcc_selinux(8)NAMEdcc_selinux - Security Enhanced Linux Policy for the dcc processes
DESCRIPTION
Security-Enhanced Linux secures the dcc processes via flexible manda‐
tory access control.
NSSWITCH DOMAIN
If you want to allow users to login using a sssd serve for the
dccifd_t, dccm_t, dcc_client_t, dcc_dbclean_t, dccd_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
dccifd_t, dccm_t, dcc_client_t, dcc_dbclean_t, dccd_t, you must turn on
the allow_kerberos boolean.
setsebool -P allow_kerberos 1
If you want to allow system to run with NI for the dccifd_t, dccm_t,
dcc_client_t, dcc_dbclean_t, dccd_t, you must turn on the allow_ypbind
boolean.
setsebool -P allow_ypbind 1
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 policy is very flexible allowing users to setup their dcc
processes in as secure a method as possible.
The following file types are defined for dcc:
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:
/var/lib/dcc/map, /etc/dcc/map, /var/run/dcc/map, /var/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.
dcc_dbclean_exec_t
- Set files with the dcc_dbclean_exec_t type, if you want to transition
an executable to the dcc_dbclean_t domain.
dcc_dbclean_tmp_t
- Set files with the dcc_dbclean_tmp_t type, if you want to store dcc
dbclean temporary files in the /tmp directories.
dcc_var_run_t
- Set files with the dcc_var_run_t type, if you want to store the dcc
files under the /run directory.
dcc_var_t
- Set files with the dcc_var_t type, if you want to store the files
under the /var directory.
Paths:
/etc/dcc(/.*)?, /var/dcc(/.*)?, /var/lib/dcc(/.*)?
dccd_exec_t
- Set files with the dccd_exec_t type, if you want to transition an
executable to the dccd_t domain.
dccd_tmp_t
- Set files with the dccd_tmp_t type, if you want to store dccd tempo‐
rary files in the /tmp directories.
dccd_var_run_t
- Set files with the dccd_var_run_t type, if you want to store the dccd
files under the /run directory.
dccifd_exec_t
- Set files with the dccifd_exec_t type, if you want to transition an
executable to the dccifd_t domain.
dccifd_tmp_t
- Set files with the dccifd_tmp_t type, if you want to store dccifd
temporary files in the /tmp directories.
dccifd_var_run_t
- Set files with the dccifd_var_run_t type, if you want to store the
dccifd files under the /run directory.
Paths:
/etc/dcc/dccifd, /var/run/dcc/dccifd
dccm_exec_t
- Set files with the dccm_exec_t type, if you want to transition an
executable to the dccm_t domain.
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 directory.
Note: File context can be temporarily modified with the chcon command.
If you want to permanantly 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.
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 dcc policy is very flexible allowing users to setup their dcc
processes in as secure a method as possible.
The following port types are defined for dcc:
dcc_port_t
Default Defined Ports:
udp 6276,6277
dccm_port_t
Default Defined Ports:
tcp 5679
udp 5679
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 policy is very flexible allowing users to setup their dcc processes
in as secure a method as possible.
The following process types are defined for dcc:
dccm_t, dcc_client_t, dcc_dbclean_t, dccifd_t, dccd_t
Note: semanage permissive -a PROCESS_TYPE can be used to make a process
type permissive. Permissive process types are not denied access by
SELinux. AVC messages will still be generated.
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
system-config-selinux is a GUI tool available to customize SELinux pol‐
icy settings.
