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 dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59
60 setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow system to run with NIS, you must turn on the
72 nis_enabled boolean. Disabled by default.
73
74 setsebool -P nis_enabled 1
75
76
77
79 SELinux defines port types to represent TCP and UDP ports.
80
81 You can see the types associated with a port by using the following
82 command:
83
84 semanage port -l
85
86
87 Policy governs the access confined processes have to these ports.
88 SELinux dccd policy is very flexible allowing users to setup their dccd
89 processes in as secure a method as possible.
90
91 The following port types are defined for dccd:
92
93
94 dcc_port_t
95
96
97
98 Default Defined Ports:
99 udp 6276,6277
100
102 The SELinux process type dccd_t can manage files labeled with the fol‐
103 lowing file types. The paths listed are the default paths for these
104 file types. Note the processes UID still need to have DAC permissions.

177 SELinux requires files to have an extended attribute to define the file
178 type.
179
180 You can see the context of a file using the -Z option to ls
181
182 Policy governs the access confined processes have to these files.
183 SELinux dccd policy is very flexible allowing users to setup their dccd
184 processes in as secure a method as possible.
185
186 STANDARD FILE CONTEXT
187
188 SELinux defines the file context types for the dccd, if you wanted to
189 store files with these types in a different paths, you need to execute
190 the semanage command to specify alternate labeling and then use re‐
191 storecon to put the labels on disk.
192
193 semanage fcontext -a -t dccd_exec_t '/srv/dccd/content(/.*)?'
194 restorecon -R -v /srv/mydccd_content
195
196 Note: SELinux often uses regular expressions to specify labels that
197 match multiple files.
198
199 The following file types are defined for dccd:
200
201
202
203 dccd_exec_t
204
205 - Set files with the dccd_exec_t type, if you want to transition an ex‐
206 ecutable to the dccd_t domain.
207
208
209 Paths:
210 /usr/sbin/dccd, /usr/libexec/dcc/dccd
211
212
213 dccd_tmp_t
214
215 - Set files with the dccd_tmp_t type, if you want to store dccd tempo‐
216 rary files in the /tmp directories.
217
218
219
220 dccd_var_run_t
221
222 - Set files with the dccd_var_run_t type, if you want to store the dccd
223 files under the /run or /var/run directory.
224
225
226
227 Note: File context can be temporarily modified with the chcon command.
228 If you want to permanently change the file context you need to use the
229 semanage fcontext command. This will modify the SELinux labeling data‐
230 base. You will need to use restorecon to apply the labels.
231
232
234 semanage fcontext can also be used to manipulate default file context
235 mappings.
236
237 semanage permissive can also be used to manipulate whether or not a
238 process type is permissive.
239
240 semanage module can also be used to enable/disable/install/remove pol‐
241 icy modules.
242
243 semanage port can also be used to manipulate the port definitions
244
245 semanage boolean can also be used to manipulate the booleans
246
247
248 system-config-selinux is a GUI tool available to customize SELinux pol‐
249 icy settings.
