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 allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64 If you want to allow system to run with NIS, you must turn on the
68 nis_enabled boolean. Disabled by default.
69 setsebool -P nis_enabled 1
71
75 The SELinux process type snapperd_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux snapperd policy is very flexible allowing users to setup their
138 snapperd processes in as secure a method as possible.
139 STANDARD FILE CONTEXT
141 SELinux defines the file context types for the snapperd, if you wanted
143 to store files with these types in a diffent paths, you need to execute
144 the semanage command to specify alternate labeling and then use re‐
145 storecon to put the labels on disk.
146 semanage fcontext -a -t snapperd_data_t '/srv/mysnapperd_content(/.*)?'
148 restorecon -R -v /srv/mysnapperd_content
149 Note: SELinux often uses regular expressions to specify labels that
151 match multiple files.
152 The following file types are defined for snapperd:
154 snapperd_conf_t
158 - Set files with the snapperd_conf_t type, if you want to treat the
160 files as snapperd configuration data, usually stored under the /etc di‐
161 rectory.
162 Paths:
165 /etc/snapper(/.*)?, /etc/sysconfig/snapper
166 snapperd_data_t
169 - Set files with the snapperd_data_t type, if you want to treat the
171 files as snapperd content.
172 Paths:
175 /mnt/(.*/)?.snapshots(/.*)?, /.snapshots(/.*)?, /etc/.snap‐
176 shots(/.*)?, /usr/.snapshots(/.*)?, /var/.snapshots(/.*)?,
177 /home/(.*/)?.snapshots(/.*)?
178 snapperd_exec_t
181 - Set files with the snapperd_exec_t type, if you want to transition an
183 executable to the snapperd_t domain.
184 Paths:
187 /usr/sbin/snapperd, /usr/lib/snapper/systemd-helper
188 snapperd_log_t
191 - Set files with the snapperd_log_t type, if you want to treat the data
193 as snapperd log data, usually stored under the /var/log directory.
194 Note: File context can be temporarily modified with the chcon command.
198 If you want to permanently change the file context you need to use the
199 semanage fcontext command. This will modify the SELinux labeling data‐
200 base. You will need to use restorecon to apply the labels.
201
204 semanage fcontext can also be used to manipulate default file context
205 mappings.
206 semanage permissive can also be used to manipulate whether or not a
208 process type is permissive.
209 semanage module can also be used to enable/disable/install/remove pol‐
211 icy modules.
212 semanage boolean can also be used to manipulate the booleans
214 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
