NAME

6       oracleasm_selinux  -  Security  Enhanced Linux Policy for the oracleasm
7       processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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.
57
58
59
60       If you want to allow all daemons to write corefiles to /, you must turn

MANAGED FILES

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.

FILE CONTEXTS

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

COMMANDS

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.
