6 oracleasm_selinux - Security Enhanced Linux Policy for the oracleasm
7 processes
8
10 Security-Enhanced Linux secures the oracleasm processes via flexible
11 mandatory access control.
12
13 The oracleasm processes execute with the oracleasm_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep oracleasm_t
20
21
22
24 The oracleasm_t SELinux type can be entered via the oracleasm_exec_t
25 file type.
26
27 The default entrypoint paths for the oracleasm_t domain are the follow‐
28 ing:
29
30 /usr/sbin/oracleasm
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 oracleasm policy is very flexible allowing users to setup their ora‐
40 cleasm processes in as secure a method as possible.
41
42 The following process types are defined for oracleasm:
43
44 oracleasm_t
45
46 Note: semanage permissive -a oracleasm_t can be used to make the
47 process type oracleasm_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. ora‐
54 cleasm policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run oracleasm with the tightest access
56 possible.

136
137 setsebool -P global_ssp 1
138
139

142 The SELinux process type oracleasm_t can manage files labeled with the
143 following file types. The paths listed are the default paths for these
144 file types. Note the processes UID still need to have DAC permissions.

195 SELinux requires files to have an extended attribute to define the file
196 type.
197
198 You can see the context of a file using the -Z option to ls
199
200 Policy governs the access confined processes have to these files.
201 SELinux oracleasm policy is very flexible allowing users to setup their
202 oracleasm processes in as secure a method as possible.
203
204 STANDARD FILE CONTEXT
205
206 SELinux defines the file context types for the oracleasm, if you wanted
207 to store files with these types in a diffent paths, you need to execute
208 the semanage command to sepecify alternate labeling and then use
209 restorecon to put the labels on disk.
210
211 semanage fcontext -a -t oracleasmfs_t '/srv/myoracleasm_content(/.*)?'
212 restorecon -R -v /srv/myoracleasm_content
213
214 Note: SELinux often uses regular expressions to specify labels that
215 match multiple files.
216
217 The following file types are defined for oracleasm:
218
219
220
221 oracleasm_conf_t
222
223 - Set files with the oracleasm_conf_t type, if you want to treat the
224 files as oracleasm configuration data, usually stored under the /etc
225 directory.
226
227
228 Paths:
229 /etc/sysconfig/oracleasm(/.*)?, /etc/sysconfig/oracleasm-_dev_ora‐
230 cleasm
231
232
233 oracleasm_exec_t
234
235 - Set files with the oracleasm_exec_t type, if you want to transition
236 an executable to the oracleasm_t domain.
237
238
239
240 oracleasm_initrc_exec_t
241
242 - Set files with the oracleasm_initrc_exec_t type, if you want to tran‐
243 sition an executable to the oracleasm_initrc_t domain.
244
245
246
247 oracleasm_tmp_t
248
249 - Set files with the oracleasm_tmp_t type, if you want to store ora‐
250 cleasm temporary files in the /tmp directories.
251
252
253
254 oracleasmfs_t
255
256 - Set files with the oracleasmfs_t type, if you want to treat the files
257 as oracleasmfs data.
258
259
260
261 Note: File context can be temporarily modified with the chcon command.
262 If you want to permanently change the file context you need to use the
263 semanage fcontext command. This will modify the SELinux labeling data‐
264 base. You will need to use restorecon to apply the labels.
265
266
268 semanage fcontext can also be used to manipulate default file context
269 mappings.
270
271 semanage permissive can also be used to manipulate whether or not a
272 process type is permissive.
273
274 semanage module can also be used to enable/disable/install/remove pol‐
275 icy modules.
276
277 semanage boolean can also be used to manipulate the booleans
278
279
280 system-config-selinux is a GUI tool available to customize SELinux pol‐
281 icy settings.
