dccd_selinux(8) SELinux Policy documentation for dccd dccd_selinux(8)

NAME dccd_selinux - Security Enhanced Linux Policy for the dccd processes

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

The dccd processes execute with the dccd_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 dccd_t

ENTRYPOINTS The dccd_t SELinux type can be entered via the "dccd_exec_t" file type. The default entrypoint paths for the dccd_t domain are the following:"

/usr/libexec/dcc/dccd

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

The following process types are defined for dccd:

dccm_t, dcc_client_t, dcc_dbclean_t, dccifd_t, dccd_t

Note: semanage permissive -a dccd_t

can be used to make the process type dccd_t permissive. Permissive pro- cess types are not denied access by SELinux. AVC messages will still be generated.

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

The following file types are defined for dccd:

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.

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

The following port types are defined for dccd:

dcc_port_t

Default Defined Ports: udp 6276,6277

dccm_port_t

Default Defined Ports: tcp 5679 udp 5679

MANAGED FILES The SELinux process type dccd_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.

dcc_client_map_t

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

dcc_var_t

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

dccd_tmp_t

dccd_var_run_t

initrc_tmp_t

mnt_t

/mnt(/[^/]*) /mnt(/[^/]*)? /rhev(/[^/]*)? /media(/[^/]*) /media(/[^/]*)? /etc/rhgb(/.*)? /media/.hal-.* /net /afs /misc /rhev

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.
