6 dlm_controld_selinux - Security Enhanced Linux Policy for the dlm_con‐
7 trold processes
8
10 Security-Enhanced Linux secures the dlm_controld processes via flexible
11 mandatory access control.
12
13 The dlm_controld processes execute with the dlm_controld_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep dlm_controld_t
20
21
22
24 The dlm_controld_t SELinux type can be entered via the dlm_con‐
25 trold_exec_t file type.
26
27 The default entrypoint paths for the dlm_controld_t domain are the fol‐
28 lowing:
29
30 /usr/sbin/dlm_controld
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 dlm_controld policy is very flexible allowing users to setup their
40 dlm_controld processes in as secure a method as possible.
41
42 The following process types are defined for dlm_controld:
43
44 dlm_controld_t
45
46 Note: semanage permissive -a dlm_controld_t can be used to make the
47 process type dlm_controld_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 dlm_controld policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run dlm_controld with the tight‐
56 est access possible.

59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow cluster administrative cluster domains memcheck-
69 amd64- to use executable memory, you must turn on the clus‐
70 ter_use_execmem boolean. Disabled by default.
71
72 setsebool -P cluster_use_execmem 1
73
74
75
76 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78
79 setsebool -P fips_mode 1
80
81
82
83 If you want to allow confined applications to run with kerberos, you
84 must turn on the kerberos_enabled boolean. Enabled by default.
85
86 setsebool -P kerberos_enabled 1
87
88
89
90 If you want to allow system to run with NIS, you must turn on the
91 nis_enabled boolean. Disabled by default.
92
93 setsebool -P nis_enabled 1
94
95
96
97 If you want to allow confined applications to use nscd shared memory,
98 you must turn on the nscd_use_shm boolean. Disabled by default.
99
100 setsebool -P nscd_use_shm 1
101

103
105 The SELinux process type dlm_controld_t can manage files labeled with
106 the following file types. The paths listed are the default paths for
107 these file types. Note the processes UID still need to have DAC per‐
108 missions.

171 SELinux requires files to have an extended attribute to define the file
172 type.
173
174 You can see the context of a file using the -Z option to ls
175
176 Policy governs the access confined processes have to these files.
177 SELinux dlm_controld policy is very flexible allowing users to setup
178 their dlm_controld processes in as secure a method as possible.
179
180 EQUIVALENCE DIRECTORIES
181
182
183 dlm_controld policy stores data with multiple different file context
184 types under the /var/run/dlm_controld directory. If you would like to
185 store the data in a different directory you can use the semanage com‐
186 mand to create an equivalence mapping. If you wanted to store this
187 data under the /srv dirctory you would execute the following command:
188
189 semanage fcontext -a -e /var/run/dlm_controld /srv/dlm_controld
190 restorecon -R -v /srv/dlm_controld
191
192 STANDARD FILE CONTEXT
193
194 SELinux defines the file context types for the dlm_controld, if you
195 wanted to store files with these types in a diffent paths, you need to
196 execute the semanage command to sepecify alternate labeling and then
197 use restorecon to put the labels on disk.
198
199 semanage fcontext -a -t dlm_controld_var_run_t '/srv/mydlm_con‐
200 trold_content(/.*)?'
201 restorecon -R -v /srv/mydlm_controld_content
202
203 Note: SELinux often uses regular expressions to specify labels that
204 match multiple files.
205
206 The following file types are defined for dlm_controld:
207
208
209
210 dlm_controld_exec_t
211
212 - Set files with the dlm_controld_exec_t type, if you want to transi‐
213 tion an executable to the dlm_controld_t domain.
214
215
216
217 dlm_controld_initrc_exec_t
218
219 - Set files with the dlm_controld_initrc_exec_t type, if you want to
220 transition an executable to the dlm_controld_initrc_t domain.
221
222
223
224 dlm_controld_tmpfs_t
225
226 - Set files with the dlm_controld_tmpfs_t type, if you want to store
227 dlm controld files on a tmpfs file system.
228
229
230
231 dlm_controld_var_log_t
232
233 - Set files with the dlm_controld_var_log_t type, if you want to treat
234 the data as dlm controld var log data, usually stored under the
235 /var/log directory.
236
237
238 Paths:
239 /var/log/dlm_controld(/.*)?, /var/log/cluster/dlm_controld.log.*
240
241
242 dlm_controld_var_run_t
243
244 - Set files with the dlm_controld_var_run_t type, if you want to store
245 the dlm controld files under the /run or /var/run directory.
246
247
248 Paths:
249 /var/run/dlm_controld(/.*)?, /var/run/dlm_controld.pid
250
251
252 Note: File context can be temporarily modified with the chcon command.
253 If you want to permanently change the file context you need to use the
254 semanage fcontext command. This will modify the SELinux labeling data‐
255 base. You will need to use restorecon to apply the labels.
256
257
259 semanage fcontext can also be used to manipulate default file context
260 mappings.
261
262 semanage permissive can also be used to manipulate whether or not a
263 process type is permissive.
264
265 semanage module can also be used to enable/disable/install/remove pol‐
266 icy modules.
267
268 semanage boolean can also be used to manipulate the booleans
269
270
271 system-config-selinux is a GUI tool available to customize SELinux pol‐
272 icy settings.
