6 sanlock_selinux - Security Enhanced Linux Policy for the sanlock pro‐
7 cesses
8
10 Security-Enhanced Linux secures the sanlock processes via flexible
11 mandatory access control.
12
13 The sanlock processes execute with the sanlock_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 sanlock_t
20
21
22
24 The sanlock_t SELinux type can be entered via the sanlock_exec_t file
25 type.
26
27 The default entrypoint paths for the sanlock_t domain are the follow‐
28 ing:
29
30 /usr/sbin/sanlock
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 sanlock policy is very flexible allowing users to setup their sanlock
40 processes in as secure a method as possible.
41
42 The following process types are defined for sanlock:
43
44 sanlock_t
45
46 Note: semanage permissive -a sanlock_t can be used to make the process
47 type sanlock_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. sanlock
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run sanlock with the tightest access possi‐
56 ble.
57
58
59
60 If you want to allow sanlock to read/write user home directories, you
61 must turn on the sanlock_enable_home_dirs boolean. Disabled by default.
62
63 setsebool -P sanlock_enable_home_dirs 1
64
65
66
67 If you want to allow sanlock to read/write fuse files, you must turn on
68 the sanlock_use_fusefs boolean. Disabled by default.
69
70 setsebool -P sanlock_use_fusefs 1
71
72
73
74 If you want to allow sanlock to manage nfs files, you must turn on the
75 sanlock_use_nfs boolean. Disabled by default.
76
77 setsebool -P sanlock_use_nfs 1
78
79
80
81 If you want to allow sanlock to manage cifs files, you must turn on the
82 sanlock_use_samba boolean. Disabled by default.
83
84 setsebool -P sanlock_use_samba 1
85
86
87
88 If you want to allow all domains to execute in fips_mode, you must turn
89 on the fips_mode boolean. Enabled by default.
90
91 setsebool -P fips_mode 1
92
93
94
95 If you want to allow system to run with NIS, you must turn on the
96 nis_enabled boolean. Disabled by default.
97
98 setsebool -P nis_enabled 1
99

101
103 The SELinux process type sanlock_t can manage files labeled with the
104 following file types. The paths listed are the default paths for these
105 file types. Note the processes UID still need to have DAC permissions.

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