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.

116 SELinux requires files to have an extended attribute to define the file
117 type.
118 You can see the context of a file using the -Z option to ls
120 Policy governs the access confined processes have to these files.
122 SELinux snapperd policy is very flexible allowing users to setup their
123 snapperd processes in as secure a method as possible.
124 STANDARD FILE CONTEXT
126 SELinux defines the file context types for the snapperd, if you wanted
128 to store files with these types in a diffent paths, you need to execute
129 the semanage command to sepecify alternate labeling and then use
130 restorecon to put the labels on disk.
131 semanage fcontext -a -t snapperd_data_t '/srv/mysnapperd_content(/.*)?'
133 restorecon -R -v /srv/mysnapperd_content
134 Note: SELinux often uses regular expressions to specify labels that
136 match multiple files.
137 The following file types are defined for snapperd:
139 snapperd_conf_t
143 - Set files with the snapperd_conf_t type, if you want to treat the
145 files as snapperd configuration data, usually stored under the /etc
146 directory.
147 Paths:
150 /etc/snapper(/.*)?, /etc/sysconfig/snapper
151 snapperd_data_t
154 - Set files with the snapperd_data_t type, if you want to treat the
156 files as snapperd content.
157 Paths:
160 /mnt/(.*/)?.snapshots(/.*)?, /.snapshots(/.*)?, /etc/.snap‐
161 shots(/.*)?, /usr/.snapshots(/.*)?, /var/.snapshots(/.*)?,
162 /home/(.*/)?.snapshots(/.*)?
163 snapperd_exec_t
166 - Set files with the snapperd_exec_t type, if you want to transition an
168 executable to the snapperd_t domain.
169 Paths:
172 /usr/sbin/snapperd, /usr/lib/snapper/systemd-helper
173 snapperd_log_t
176 - Set files with the snapperd_log_t type, if you want to treat the data
178 as snapperd log data, usually stored under the /var/log directory.
179 Note: File context can be temporarily modified with the chcon command.
183 If you want to permanently change the file context you need to use the
184 semanage fcontext command. This will modify the SELinux labeling data‐
185 base. You will need to use restorecon to apply the labels.
186
189 semanage fcontext can also be used to manipulate default file context
190 mappings.
191 semanage permissive can also be used to manipulate whether or not a
193 process type is permissive.
194 semanage module can also be used to enable/disable/install/remove pol‐
196 icy modules.
197 semanage boolean can also be used to manipulate the booleans
199 system-config-selinux is a GUI tool available to customize SELinux pol‐
202 icy settings.
