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 rsync sys_admin capability. This capability is re‐
79 quired to restore files with extended attributes in the "trusted" name‐
80 space, you must turn on the rsync_sys_admin boolean. Disabled by de‐
81 fault.
82 setsebool -P rsync_sys_admin 1
84 If you want to allow all domains to execute in fips_mode, you must turn
88 on the fips_mode boolean. Enabled by default.
89 setsebool -P fips_mode 1
91
95 SELinux defines port types to represent TCP and UDP ports.
96 You can see the types associated with a port by using the following
98 command:
99 semanage port -l
101 Policy governs the access confined processes have to these ports.
104 SELinux rsync policy is very flexible allowing users to setup their
105 rsync processes in as secure a method as possible.
106 The following port types are defined for rsync:
108 rsync_port_t
111 Default Defined Ports:
115 tcp 873
116 udp 873
117
119 The SELinux process type rsync_t can manage files labeled with the fol‐
120 lowing file types. The paths listed are the default paths for these
121 file types. Note the processes UID still need to have DAC permissions.

215 SELinux requires files to have an extended attribute to define the file
216 type.
217 You can see the context of a file using the -Z option to ls
219 Policy governs the access confined processes have to these files.
221 SELinux rsync policy is very flexible allowing users to setup their
222 rsync processes in as secure a method as possible.
223 STANDARD FILE CONTEXT
225 SELinux defines the file context types for the rsync, if you wanted to
227 store files with these types in a diffent paths, you need to execute
228 the semanage command to specify alternate labeling and then use re‐
229 storecon to put the labels on disk.
230 semanage fcontext -a -t rsync_var_run_t '/srv/myrsync_content(/.*)?'
232 restorecon -R -v /srv/myrsync_content
233 Note: SELinux often uses regular expressions to specify labels that
235 match multiple files.
236 The following file types are defined for rsync:
238 rsync_data_t
242 - Set files with the rsync_data_t type, if you want to treat the files
244 as rsync content.
245 rsync_etc_t
249 - Set files with the rsync_etc_t type, if you want to store rsync files
251 in the /etc directories.
252 rsync_exec_t
256 - Set files with the rsync_exec_t type, if you want to transition an
258 executable to the rsync_t domain.
259 rsync_log_t
263 - Set files with the rsync_log_t type, if you want to treat the data as
265 rsync log data, usually stored under the /var/log directory.
266 rsync_tmp_t
270 - Set files with the rsync_tmp_t type, if you want to store rsync tem‐
272 porary files in the /tmp directories.
273 rsync_var_run_t
277 - Set files with the rsync_var_run_t type, if you want to store the
279 rsync files under the /run or /var/run directory.
280 Paths:
283 /var/run/rsyncd.lock, /var/run/swift_server.lock
284 Note: File context can be temporarily modified with the chcon command.
287 If you want to permanently change the file context you need to use the
288 semanage fcontext command. This will modify the SELinux labeling data‐
289 base. You will need to use restorecon to apply the labels.
290
293 If you want to share files with multiple domains (Apache, FTP, rsync,
294 Samba), you can set a file context of public_content_t and public_con‐
295 tent_rw_t. These context allow any of the above domains to read the
296 content. If you want a particular domain to write to the public_con‐
297 tent_rw_t domain, you must set the appropriate boolean.
298 Allow rsync servers to read the /var/rsync directory by adding the pub‐
300 lic_content_t file type to the directory and by restoring the file
301 type.
302 semanage fcontext -a -t public_content_t "/var/rsync(/.*)?"
304 restorecon -F -R -v /var/rsync
305 Allow rsync servers to read and write /var/rsync/incoming by adding the
307 public_content_rw_t type to the directory and by restoring the file
308 type. You also need to turn on the rsync_anon_write boolean.
309 semanage fcontext -a -t public_content_rw_t "/var/rsync/incoming(/.*)?"
311 restorecon -F -R -v /var/rsync/incoming
312 setsebool -P rsync_anon_write 1
313 If you want to allow rsync to modify public files used for public file
316 transfer services. Files/Directories must be labeled public_con‐
317 tent_rw_t., you must turn on the rsync_anon_write boolean.
318 setsebool -P rsync_anon_write 1
320
323 semanage fcontext can also be used to manipulate default file context
324 mappings.
325 semanage permissive can also be used to manipulate whether or not a
327 process type is permissive.
328 semanage module can also be used to enable/disable/install/remove pol‐
330 icy modules.
331 semanage port can also be used to manipulate the port definitions
333 semanage boolean can also be used to manipulate the booleans
335 system-config-selinux is a GUI tool available to customize SELinux pol‐
338 icy settings.
