6 rsync_selinux - Security Enhanced Linux Policy for the rsync processes
7
9 Security-Enhanced Linux secures the rsync processes via flexible manda‐
10 tory access control.
11 The rsync processes execute with the rsync_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep rsync_t
19
23 The rsync_t SELinux type can be entered via the rsync_exec_t file type.
24 The default entrypoint paths for the rsync_t domain are the following:
26 /usr/bin/rsync
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 rsync policy is very flexible allowing users to setup their rsync pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for rsync:
40 rsync_t
42 Note: semanage permissive -a rsync_t can be used to make the process
44 type rsync_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. rsync
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run rsync with the tightest access possible.
53 If you want to allow rsync to run as a client, you must turn on the
57 rsync_client boolean. Disabled by default.
58 setsebool -P rsync_client 1
60 If you want to allow rsync to export any files/directories read only,
64 you must turn on the rsync_export_all_ro boolean. Disabled by default.
65 setsebool -P rsync_export_all_ro 1
67 If you want to allow rsync server to manage all files/directories on
71 the system, you must turn on the rsync_full_access boolean. Disabled by
72 default.
73 setsebool -P rsync_full_access 1
75 If you want to allow all domains to execute in fips_mode, you must turn
79 on the fips_mode boolean. Enabled by default.
80 setsebool -P fips_mode 1
82
86 SELinux defines port types to represent TCP and UDP ports.
87 You can see the types associated with a port by using the following
89 command:
90 semanage port -l
92 Policy governs the access confined processes have to these ports.
95 SELinux rsync policy is very flexible allowing users to setup their
96 rsync processes in as secure a method as possible.
97 The following port types are defined for rsync:
99 rsync_port_t
102 Default Defined Ports:
106 tcp 873
107 udp 873
108
110 The SELinux process type rsync_t can manage files labeled with the fol‐
111 lowing file types. The paths listed are the default paths for these
112 file types. Note the processes UID still need to have DAC permissions.

188 SELinux requires files to have an extended attribute to define the file
189 type.
190 You can see the context of a file using the -Z option to ls
192 Policy governs the access confined processes have to these files.
194 SELinux rsync policy is very flexible allowing users to setup their
195 rsync processes in as secure a method as possible.
196 STANDARD FILE CONTEXT
198 SELinux defines the file context types for the rsync, if you wanted to
200 store files with these types in a diffent paths, you need to execute
201 the semanage command to sepecify alternate labeling and then use
202 restorecon to put the labels on disk.
203 semanage fcontext -a -t rsync_var_run_t '/srv/myrsync_content(/.*)?'
205 restorecon -R -v /srv/myrsync_content
206 Note: SELinux often uses regular expressions to specify labels that
208 match multiple files.
209 The following file types are defined for rsync:
211 rsync_data_t
215 - Set files with the rsync_data_t type, if you want to treat the files
217 as rsync content.
218 rsync_etc_t
222 - Set files with the rsync_etc_t type, if you want to store rsync files
224 in the /etc directories.
225 rsync_exec_t
229 - Set files with the rsync_exec_t type, if you want to transition an
231 executable to the rsync_t domain.
232 rsync_log_t
236 - Set files with the rsync_log_t type, if you want to treat the data as
238 rsync log data, usually stored under the /var/log directory.
239 rsync_tmp_t
243 - Set files with the rsync_tmp_t type, if you want to store rsync tem‐
245 porary files in the /tmp directories.
246 rsync_var_run_t
250 - Set files with the rsync_var_run_t type, if you want to store the
252 rsync files under the /run or /var/run directory.
253 Paths:
256 /var/run/rsyncd.lock, /var/run/swift_server.lock
257 Note: File context can be temporarily modified with the chcon command.
260 If you want to permanently change the file context you need to use the
261 semanage fcontext command. This will modify the SELinux labeling data‐
262 base. You will need to use restorecon to apply the labels.
263
266 If you want to share files with multiple domains (Apache, FTP, rsync,
267 Samba), you can set a file context of public_content_t and public_con‐
268 tent_rw_t. These context allow any of the above domains to read the
269 content. If you want a particular domain to write to the public_con‐
270 tent_rw_t domain, you must set the appropriate boolean.
271 Allow rsync servers to read the /var/rsync directory by adding the pub‐
273 lic_content_t file type to the directory and by restoring the file
274 type.
275 semanage fcontext -a -t public_content_t "/var/rsync(/.*)?"
277 restorecon -F -R -v /var/rsync
278 Allow rsync servers to read and write /var/rsync/incoming by adding the
280 public_content_rw_t type to the directory and by restoring the file
281 type. You also need to turn on the rsync_anon_write boolean.
282 semanage fcontext -a -t public_content_rw_t "/var/rsync/incoming(/.*)?"
284 restorecon -F -R -v /var/rsync/incoming
285 setsebool -P rsync_anon_write 1
286 If you want to allow rsync to modify public files used for public file
289 transfer services. Files/Directories must be labeled public_con‐
290 tent_rw_t., you must turn on the rsync_anon_write boolean.
291 setsebool -P rsync_anon_write 1
293
296 semanage fcontext can also be used to manipulate default file context
297 mappings.
298 semanage permissive can also be used to manipulate whether or not a
300 process type is permissive.
301 semanage module can also be used to enable/disable/install/remove pol‐
303 icy modules.
304 semanage port can also be used to manipulate the port definitions
306 semanage boolean can also be used to manipulate the booleans
308 system-config-selinux is a GUI tool available to customize SELinux pol‐
311 icy settings.
