6 fenced_selinux - Security Enhanced Linux Policy for the fenced pro‐
7 cesses
8
10 Security-Enhanced Linux secures the fenced processes via flexible
11 mandatory access control.
12
13 The fenced processes execute with the fenced_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep fenced_t
20
21
22
24 The fenced_t SELinux type can be entered via the fenced_exec_t file
25 type.
26
27 The default entrypoint paths for the fenced_t domain are the following:
28
29 /usr/sbin/fenced, /usr/sbin/fence_node, /usr/sbin/fence_tool,
30 /usr/sbin/fence_virtd, /usr/sbin/fence_sanlockd, /usr/share/clus‐
31 ter/fence_scsi_check, /usr/share/cluster/fence_mpath_check,
32 /usr/share/cluster/fence_scsi_check.pl, /usr/lib/systemd/systemd-
33 fence_sanlockd, /usr/share/cluster/fence_scsi_check_hardreboot,
34 /usr/share/cluster/fence_mpath_check_hardreboot
35
37 SELinux defines process types (domains) for each process running on the
38 system
39
40 You can see the context of a process using the -Z option to ps
41
42 Policy governs the access confined processes have to files. SELinux
43 fenced policy is very flexible allowing users to setup their fenced
44 processes in as secure a method as possible.
45
46 The following process types are defined for fenced:
47
48 fenced_t
49
50 Note: semanage permissive -a fenced_t can be used to make the process
51 type fenced_t permissive. SELinux does not deny access to permissive
52 process types, but the AVC (SELinux denials) messages are still gener‐
53 ated.
54
55
57 SELinux policy is customizable based on least access required. fenced
58 policy is extremely flexible and has several booleans that allow you to
59 manipulate the policy and run fenced with the tightest access possible.
60
61
62
63 If you want to determine whether fenced can connect to the TCP network,
64 you must turn on the fenced_can_network_connect boolean. Disabled by
65 default.
66
67 setsebool -P fenced_can_network_connect 1
68
69
70
71 If you want to determine whether fenced can use ssh, you must turn on
72 the fenced_can_ssh boolean. Disabled by default.
73
74 setsebool -P fenced_can_ssh 1
75
76
77
78 If you want to allow cluster administrative cluster domains memcheck-
79 amd64- to use executable memory, you must turn on the clus‐
80 ter_use_execmem boolean. Disabled by default.
81
82 setsebool -P cluster_use_execmem 1
83
84
85
86 If you want to allow all domains to execute in fips_mode, you must turn
87 on the fips_mode boolean. Enabled by default.
88
89 setsebool -P fips_mode 1
90
91
92
94 The SELinux process type fenced_t can manage files labeled with the
95 following file types. The paths listed are the default paths for these
96 file types. Note the processes UID still need to have DAC permissions.

165 SELinux requires files to have an extended attribute to define the file
166 type.
167
168 You can see the context of a file using the -Z option to ls
169
170 Policy governs the access confined processes have to these files.
171 SELinux fenced policy is very flexible allowing users to setup their
172 fenced processes in as secure a method as possible.
173
174 STANDARD FILE CONTEXT
175
176 SELinux defines the file context types for the fenced, if you wanted to
177 store files with these types in a diffent paths, you need to execute
178 the semanage command to sepecify alternate labeling and then use
179 restorecon to put the labels on disk.
180
181 semanage fcontext -a -t fenced_tmp_t '/srv/myfenced_content(/.*)?'
182 restorecon -R -v /srv/myfenced_content
183
184 Note: SELinux often uses regular expressions to specify labels that
185 match multiple files.
186
187 The following file types are defined for fenced:
188
189
190
191 fenced_exec_t
192
193 - Set files with the fenced_exec_t type, if you want to transition an
194 executable to the fenced_t domain.
195
196
197 Paths:
198 /usr/sbin/fenced, /usr/sbin/fence_node, /usr/sbin/fence_tool,
199 /usr/sbin/fence_virtd, /usr/sbin/fence_sanlockd, /usr/share/clus‐
200 ter/fence_scsi_check, /usr/share/cluster/fence_mpath_check,
201 /usr/share/cluster/fence_scsi_check.pl, /usr/lib/systemd/systemd-
202 fence_sanlockd, /usr/share/cluster/fence_scsi_check_hardreboot,
203 /usr/share/cluster/fence_mpath_check_hardreboot
204
205
206 fenced_lock_t
207
208 - Set files with the fenced_lock_t type, if you want to treat the files
209 as fenced lock data, stored under the /var/lock directory
210
211
212
213 fenced_tmp_t
214
215 - Set files with the fenced_tmp_t type, if you want to store fenced
216 temporary files in the /tmp directories.
217
218
219
220 fenced_tmpfs_t
221
222 - Set files with the fenced_tmpfs_t type, if you want to store fenced
223 files on a tmpfs file system.
224
225
226
227 fenced_var_log_t
228
229 - Set files with the fenced_var_log_t type, if you want to treat the
230 data as fenced var log data, usually stored under the /var/log direc‐
231 tory.
232
233
234
235 fenced_var_run_t
236
237 - Set files with the fenced_var_run_t type, if you want to store the
238 fenced files under the /run or /var/run directory.
239
240
241 Paths:
242 /var/run/fence.*, /var/run/cluster/fence_scsi.*, /var/run/clus‐
243 ter/mpath.devices, /var/run/cluster/fenced_override
244
245
246 Note: File context can be temporarily modified with the chcon command.
247 If you want to permanently change the file context you need to use the
248 semanage fcontext command. This will modify the SELinux labeling data‐
249 base. You will need to use restorecon to apply the labels.
250
251
253 semanage fcontext can also be used to manipulate default file context
254 mappings.
255
256 semanage permissive can also be used to manipulate whether or not a
257 process type is permissive.
258
259 semanage module can also be used to enable/disable/install/remove pol‐
260 icy modules.
261
262 semanage boolean can also be used to manipulate the booleans
263
264
265 system-config-selinux is a GUI tool available to customize SELinux pol‐
266 icy settings.
