6 deltacloudd_selinux - Security Enhanced Linux Policy for the delta‐
7 cloudd processes
8
10 Security-Enhanced Linux secures the deltacloudd processes via flexible
11 mandatory access control.
12 The deltacloudd processes execute with the deltacloudd_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep deltacloudd_t
20
24 The deltacloudd_t SELinux type can be entered via the delta‐
25 cloudd_exec_t file type.
26 The default entrypoint paths for the deltacloudd_t domain are the fol‐
28 lowing:
29 /usr/bin/deltacloudd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 deltacloudd policy is very flexible allowing users to setup their
40 deltacloudd processes in as secure a method as possible.
41 The following process types are defined for deltacloudd:
43 deltacloudd_t
45 Note: semanage permissive -a deltacloudd_t can be used to make the
47 process type deltacloudd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. delta‐
54 cloudd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run deltacloudd with the tightest
56 access possible.
57 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‐

150 must turn on the kerberos_enabled boolean. Enabled by default.
151 setsebool -P kerberos_enabled 1
153 If you want to allow system to run with NIS, you must turn on the
157 nis_enabled boolean. Disabled by default.
158 setsebool -P nis_enabled 1
160 If you want to allow confined applications to use nscd shared memory,
164 you must turn on the nscd_use_shm boolean. Disabled by default.
165 setsebool -P nscd_use_shm 1

171 The SELinux process type deltacloudd_t can manage files labeled with
172 the following file types. The paths listed are the default paths for
173 these file types. Note the processes UID still need to have DAC per‐
174 missions.

223 SELinux requires files to have an extended attribute to define the file
224 type.
225 You can see the context of a file using the -Z option to ls
227 Policy governs the access confined processes have to these files.
229 SELinux deltacloudd policy is very flexible allowing users to setup
230 their deltacloudd processes in as secure a method as possible.
231 STANDARD FILE CONTEXT
233 SELinux defines the file context types for the deltacloudd, if you
235 wanted to store files with these types in a diffent paths, you need to
236 execute the semanage command to sepecify alternate labeling and then
237 use restorecon to put the labels on disk.
238 semanage fcontext -a -t deltacloudd_var_run_t '/srv/mydeltacloudd_con‐
240 tent(/.*)?'
241 restorecon -R -v /srv/mydeltacloudd_content
242 Note: SELinux often uses regular expressions to specify labels that
244 match multiple files.
245 The following file types are defined for deltacloudd:
247 deltacloudd_exec_t
251 - Set files with the deltacloudd_exec_t type, if you want to transition
253 an executable to the deltacloudd_t domain.
254 deltacloudd_log_t
258 - Set files with the deltacloudd_log_t type, if you want to treat the
260 data as deltacloudd log data, usually stored under the /var/log direc‐
261 tory.
262 deltacloudd_tmp_t
266 - Set files with the deltacloudd_tmp_t type, if you want to store
268 deltacloudd temporary files in the /tmp directories.
269 deltacloudd_var_run_t
273 - Set files with the deltacloudd_var_run_t type, if you want to store
275 the deltacloudd files under the /run or /var/run directory.
276 Note: File context can be temporarily modified with the chcon command.
280 If you want to permanently change the file context you need to use the
281 semanage fcontext command. This will modify the SELinux labeling data‐
282 base. You will need to use restorecon to apply the labels.
283
286 semanage fcontext can also be used to manipulate default file context
287 mappings.
288 semanage permissive can also be used to manipulate whether or not a
290 process type is permissive.
291 semanage module can also be used to enable/disable/install/remove pol‐
293 icy modules.
294 semanage boolean can also be used to manipulate the booleans
296 system-config-selinux is a GUI tool available to customize SELinux pol‐
299 icy settings.
