6 dccd_selinux - Security Enhanced Linux Policy for the dccd processes
7
9 Security-Enhanced Linux secures the dccd processes via flexible manda‐
10 tory access control.
11 The dccd processes execute with the dccd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep dccd_t
19
23 The dccd_t SELinux type can be entered via the dccd_exec_t file type.
24 The default entrypoint paths for the dccd_t domain are the following:
26 /usr/sbin/dccd, /usr/libexec/dcc/dccd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 dccd policy is very flexible allowing users to setup their dccd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for dccd:
40 dcc_client_t, dcc_dbclean_t, dccd_t
42 Note: semanage permissive -a dccd_t can be used to make the process
44 type dccd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. dccd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run dccd with the tightest access possible.
53 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
71 SELinux defines port types to represent TCP and UDP ports.
72 You can see the types associated with a port by using the following
74 command:
75 semanage port -l
77 Policy governs the access confined processes have to these ports.
80 SELinux dccd policy is very flexible allowing users to setup their dccd
81 processes in as secure a method as possible.
82 The following port types are defined for dccd:
84 dcc_port_t
87 Default Defined Ports:
91 udp 6276,6277
92
94 The SELinux process type dccd_t can manage files labeled with the fol‐
95 lowing file types. The paths listed are the default paths for these
96 file types. Note the processes UID still need to have DAC permissions.

151 SELinux requires files to have an extended attribute to define the file
152 type.
153 You can see the context of a file using the -Z option to ls
155 Policy governs the access confined processes have to these files.
157 SELinux dccd policy is very flexible allowing users to setup their dccd
158 processes in as secure a method as possible.
159 STANDARD FILE CONTEXT
161 SELinux defines the file context types for the dccd, if you wanted to
163 store files with these types in a diffent paths, you need to execute
164 the semanage command to sepecify alternate labeling and then use
165 restorecon to put the labels on disk.
166 semanage fcontext -a -t dccd_var_run_t '/srv/mydccd_content(/.*)?'
168 restorecon -R -v /srv/mydccd_content
169 Note: SELinux often uses regular expressions to specify labels that
171 match multiple files.
172 The following file types are defined for dccd:
174 dccd_exec_t
178 - Set files with the dccd_exec_t type, if you want to transition an
180 executable to the dccd_t domain.
181 Paths:
184 /usr/sbin/dccd, /usr/libexec/dcc/dccd
185 dccd_tmp_t
188 - Set files with the dccd_tmp_t type, if you want to store dccd tempo‐
190 rary files in the /tmp directories.
191 dccd_var_run_t
195 - Set files with the dccd_var_run_t type, if you want to store the dccd
197 files under the /run or /var/run directory.
198 Note: File context can be temporarily modified with the chcon command.
202 If you want to permanently change the file context you need to use the
203 semanage fcontext command. This will modify the SELinux labeling data‐
204 base. You will need to use restorecon to apply the labels.
205
208 semanage fcontext can also be used to manipulate default file context
209 mappings.
210 semanage permissive can also be used to manipulate whether or not a
212 process type is permissive.
213 semanage module can also be used to enable/disable/install/remove pol‐
215 icy modules.
216 semanage port can also be used to manipulate the port definitions
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
