6 snapperd_selinux - Security Enhanced Linux Policy for the snapperd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the snapperd processes via flexible
11 mandatory access control.
12
13 The snapperd processes execute with the snapperd_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 snapperd_t
20
21
22
24 The snapperd_t SELinux type can be entered via the snapperd_exec_t file
25 type.
26
27 The default entrypoint paths for the snapperd_t domain are the follow‐
28 ing:
29
30 /usr/sbin/snapperd, /usr/lib/snapper/systemd-helper
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 snapperd policy is very flexible allowing users to setup their snapperd
40 processes in as secure a method as possible.
41
42 The following process types are defined for snapperd:
43
44 snapperd_t
45
46 Note: semanage permissive -a snapperd_t can be used to make the process
47 type snapperd_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. snap‐
54 perd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run snapperd with the tightest access
56 possible.
57
58
59
60 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‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 The SELinux process type snapperd_t can manage files labeled with the
98 following file types. The paths listed are the default paths for these
99 file types. Note the processes UID still need to have DAC permissions.

156 SELinux requires files to have an extended attribute to define the file
157 type.
158
159 You can see the context of a file using the -Z option to ls
160
161 Policy governs the access confined processes have to these files.
162 SELinux snapperd policy is very flexible allowing users to setup their
163 snapperd processes in as secure a method as possible.
164
165 STANDARD FILE CONTEXT
166
167 SELinux defines the file context types for the snapperd, if you wanted
168 to store files with these types in a diffent paths, you need to execute
169 the semanage command to sepecify alternate labeling and then use
170 restorecon to put the labels on disk.
171
172 semanage fcontext -a -t snapperd_data_t '/srv/mysnapperd_content(/.*)?'
173 restorecon -R -v /srv/mysnapperd_content
174
175 Note: SELinux often uses regular expressions to specify labels that
176 match multiple files.
177
178 The following file types are defined for snapperd:
179
180
181
182 snapperd_conf_t
183
184 - Set files with the snapperd_conf_t type, if you want to treat the
185 files as snapperd configuration data, usually stored under the /etc
186 directory.
187
188
189 Paths:
190 /etc/snapper(/.*)?, /etc/sysconfig/snapper
191
192
193 snapperd_data_t
194
195 - Set files with the snapperd_data_t type, if you want to treat the
196 files as snapperd content.
197
198
199 Paths:
200 /mnt/(.*/)?.snapshots(/.*)?, /.snapshots(/.*)?, /etc/.snap‐
201 shots(/.*)?, /usr/.snapshots(/.*)?, /var/.snapshots(/.*)?,
202 /home/(.*/)?.snapshots(/.*)?
203
204
205 snapperd_exec_t
206
207 - Set files with the snapperd_exec_t type, if you want to transition an
208 executable to the snapperd_t domain.
209
210
211 Paths:
212 /usr/sbin/snapperd, /usr/lib/snapper/systemd-helper
213
214
215 snapperd_log_t
216
217 - Set files with the snapperd_log_t type, if you want to treat the data
218 as snapperd log data, usually stored under the /var/log directory.
219
220
221
222 Note: File context can be temporarily modified with the chcon command.
223 If you want to permanently change the file context you need to use the
224 semanage fcontext command. This will modify the SELinux labeling data‐
225 base. You will need to use restorecon to apply the labels.
226
227
229 semanage fcontext can also be used to manipulate default file context
230 mappings.
231
232 semanage permissive can also be used to manipulate whether or not a
233 process type is permissive.
234
235 semanage module can also be used to enable/disable/install/remove pol‐
236 icy modules.
237
238 semanage boolean can also be used to manipulate the booleans
239
240
241 system-config-selinux is a GUI tool available to customize SELinux pol‐
242 icy settings.
