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
12 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
16 For example:
17
18 ps -eZ | grep dccd_t
19
20
21
23 The dccd_t SELinux type can be entered via the dccd_exec_t file type.
24
25 The default entrypoint paths for the dccd_t domain are the following:
26
27 /usr/sbin/dccd, /usr/libexec/dcc/dccd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 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
39 The following process types are defined for dccd:
40
41 dcc_client_t, dcc_dbclean_t, dccd_t
42
43 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
48
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
54
55
56 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
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65
66 setsebool -P nis_enabled 1
67
68
69
71 SELinux defines port types to represent TCP and UDP ports.
72
73 You can see the types associated with a port by using the following
74 command:
75
76 semanage port -l
77
78
79 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
83 The following port types are defined for dccd:
84
85
86 dcc_port_t
87
88
89
90 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.

169 SELinux requires files to have an extended attribute to define the file
170 type.
171
172 You can see the context of a file using the -Z option to ls
173
174 Policy governs the access confined processes have to these files.
175 SELinux dccd policy is very flexible allowing users to setup their dccd
176 processes in as secure a method as possible.
177
178 STANDARD FILE CONTEXT
179
180 SELinux defines the file context types for the dccd, if you wanted to
181 store files with these types in a diffent paths, you need to execute
182 the semanage command to specify alternate labeling and then use re‐
183 storecon to put the labels on disk.
184
185 semanage fcontext -a -t dccd_var_run_t '/srv/mydccd_content(/.*)?'
186 restorecon -R -v /srv/mydccd_content
187
188 Note: SELinux often uses regular expressions to specify labels that
189 match multiple files.
190
191 The following file types are defined for dccd:
192
193
194
195 dccd_exec_t
196
197 - Set files with the dccd_exec_t type, if you want to transition an ex‐
198 ecutable to the dccd_t domain.
199
200
201 Paths:
202 /usr/sbin/dccd, /usr/libexec/dcc/dccd
203
204
205 dccd_tmp_t
206
207 - Set files with the dccd_tmp_t type, if you want to store dccd tempo‐
208 rary files in the /tmp directories.
209
210
211
212 dccd_var_run_t
213
214 - Set files with the dccd_var_run_t type, if you want to store the dccd
215 files under the /run or /var/run directory.
216
217
218
219 Note: File context can be temporarily modified with the chcon command.
220 If you want to permanently change the file context you need to use the
221 semanage fcontext command. This will modify the SELinux labeling data‐
222 base. You will need to use restorecon to apply the labels.
223
224
226 semanage fcontext can also be used to manipulate default file context
227 mappings.
228
229 semanage permissive can also be used to manipulate whether or not a
230 process type is permissive.
231
232 semanage module can also be used to enable/disable/install/remove pol‐
233 icy modules.
234
235 semanage port can also be used to manipulate the port definitions
236
237 semanage boolean can also be used to manipulate the booleans
238
239
240 system-config-selinux is a GUI tool available to customize SELinux pol‐
241 icy settings.
