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 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 For example:
18 ps -eZ | grep snapperd_t
20
24 The snapperd_t SELinux type can be entered via the snapperd_exec_t file
25 type.
26 The default entrypoint paths for the snapperd_t domain are the follow‐
28 ing:
29 /usr/sbin/snapperd, /usr/lib/snapper/systemd-helper
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for snapperd:
43 snapperd_t
45 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
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 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 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 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

83 The SELinux process type snapperd_t can manage files labeled with the
84 following file types. The paths listed are the default paths for these
85 file types. Note the processes UID still need to have DAC permissions.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141 You can see the context of a file using the -Z option to ls
143 Policy governs the access confined processes have to these files.
145 SELinux snapperd policy is very flexible allowing users to setup their
146 snapperd processes in as secure a method as possible.
147 STANDARD FILE CONTEXT
149 SELinux defines the file context types for the snapperd, if you wanted
151 to store files with these types in a different paths, you need to exe‐
152 cute the semanage command to specify alternate labeling and then use
153 restorecon to put the labels on disk.
154 semanage fcontext -a -t snapperd_exec_t '/srv/snapperd/content(/.*)?'
156 restorecon -R -v /srv/mysnapperd_content
157 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160 The following file types are defined for snapperd:
162 snapperd_conf_t
166 - Set files with the snapperd_conf_t type, if you want to treat the
168 files as snapperd configuration data, usually stored under the /etc di‐
169 rectory.
170 Paths:
173 /etc/snapper(/.*)?, /etc/sysconfig/snapper
174 snapperd_data_t
177 - Set files with the snapperd_data_t type, if you want to treat the
179 files as snapperd content.
180 Paths:
183 /mnt/(.*/)?.snapshots(/.*)?, /.snapshots(/.*)?, /etc/.snap‐
184 shots(/.*)?, /usr/.snapshots(/.*)?, /var/.snapshots(/.*)?,
185 /home/.snapshots(/.*)?, /home/(.*/)?.snapshots(/.*)?
186 snapperd_exec_t
189 - Set files with the snapperd_exec_t type, if you want to transition an
191 executable to the snapperd_t domain.
192 Paths:
195 /usr/sbin/snapperd, /usr/lib/snapper/systemd-helper
196 snapperd_log_t
199 - Set files with the snapperd_log_t type, if you want to treat the data
201 as snapperd log data, usually stored under the /var/log directory.
202 Note: File context can be temporarily modified with the chcon command.
206 If you want to permanently change the file context you need to use the
207 semanage fcontext command. This will modify the SELinux labeling data‐
208 base. You will need to use restorecon to apply the labels.
209
212 semanage fcontext can also be used to manipulate default file context
213 mappings.
214 semanage permissive can also be used to manipulate whether or not a
216 process type is permissive.
217 semanage module can also be used to enable/disable/install/remove pol‐
219 icy modules.
220 semanage boolean can also be used to manipulate the booleans
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
225 icy settings.
