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 dontaudit all daemons scheduling requests (setsched,
88 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
89 Enabled by default.
90 setsebool -P daemons_dontaudit_scheduling 1
92 If you want to allow all domains to execute in fips_mode, you must turn
96 on the fips_mode boolean. Enabled by default.
97 setsebool -P fips_mode 1
99 If you want to allow system to run with NIS, you must turn on the
103 nis_enabled boolean. Disabled by default.
104 setsebool -P nis_enabled 1
106
110 SELinux defines port types to represent TCP and UDP ports.
111 You can see the types associated with a port by using the following
113 command:
114 semanage port -l
116 Policy governs the access confined processes have to these ports.
119 SELinux rsync policy is very flexible allowing users to setup their
120 rsync processes in as secure a method as possible.
121 The following port types are defined for rsync:
123 rsync_port_t
126 Default Defined Ports:
130 tcp 873
131 udp 873
132
134 The SELinux process type rsync_t can manage files labeled with the fol‐
135 lowing file types. The paths listed are the default paths for these
136 file types. Note the processes UID still need to have DAC permissions.

230 SELinux requires files to have an extended attribute to define the file
231 type.
232 You can see the context of a file using the -Z option to ls
234 Policy governs the access confined processes have to these files.
236 SELinux rsync policy is very flexible allowing users to setup their
237 rsync processes in as secure a method as possible.
238 STANDARD FILE CONTEXT
240 SELinux defines the file context types for the rsync, if you wanted to
242 store files with these types in a different paths, you need to execute
243 the semanage command to specify alternate labeling and then use re‐
244 storecon to put the labels on disk.
245 semanage fcontext -a -t rsync_exec_t '/srv/rsync/content(/.*)?'
247 restorecon -R -v /srv/myrsync_content
248 Note: SELinux often uses regular expressions to specify labels that
250 match multiple files.
251 The following file types are defined for rsync:
253 rsync_data_t
257 - Set files with the rsync_data_t type, if you want to treat the files
259 as rsync content.
260 rsync_etc_t
264 - Set files with the rsync_etc_t type, if you want to store rsync files
266 in the /etc directories.
267 rsync_exec_t
271 - Set files with the rsync_exec_t type, if you want to transition an
273 executable to the rsync_t domain.
274 rsync_log_t
278 - Set files with the rsync_log_t type, if you want to treat the data as
280 rsync log data, usually stored under the /var/log directory.
281 rsync_tmp_t
285 - Set files with the rsync_tmp_t type, if you want to store rsync tem‐
287 porary files in the /tmp directories.
288 rsync_var_run_t
292 - Set files with the rsync_var_run_t type, if you want to store the
294 rsync files under the /run or /var/run directory.
295 Paths:
298 /var/run/rsyncd.lock, /var/run/swift_server.lock
299 Note: File context can be temporarily modified with the chcon command.
302 If you want to permanently change the file context you need to use the
303 semanage fcontext command. This will modify the SELinux labeling data‐
304 base. You will need to use restorecon to apply the labels.
305
308 If you want to share files with multiple domains (Apache, FTP, rsync,
309 Samba), you can set a file context of public_content_t and public_con‐
310 tent_rw_t. These context allow any of the above domains to read the
311 content. If you want a particular domain to write to the public_con‐
312 tent_rw_t domain, you must set the appropriate boolean.
313 Allow rsync servers to read the /var/rsync directory by adding the pub‐
315 lic_content_t file type to the directory and by restoring the file
316 type.
317 semanage fcontext -a -t public_content_t "/var/rsync(/.*)?"
319 restorecon -F -R -v /var/rsync
320 Allow rsync servers to read and write /var/rsync/incoming by adding the
322 public_content_rw_t type to the directory and by restoring the file
323 type. You also need to turn on the rsync_anon_write boolean.
324 semanage fcontext -a -t public_content_rw_t "/var/rsync/incoming(/.*)?"
326 restorecon -F -R -v /var/rsync/incoming
327 setsebool -P rsync_anon_write 1
328 If you want to allow rsync to modify public files used for public file
331 transfer services. Files/Directories must be labeled public_con‐
332 tent_rw_t., you must turn on the rsync_anon_write boolean.
333 setsebool -P rsync_anon_write 1
335
338 semanage fcontext can also be used to manipulate default file context
339 mappings.
340 semanage permissive can also be used to manipulate whether or not a
342 process type is permissive.
343 semanage module can also be used to enable/disable/install/remove pol‐
345 icy modules.
346 semanage port can also be used to manipulate the port definitions
348 semanage boolean can also be used to manipulate the booleans
350 system-config-selinux is a GUI tool available to customize SELinux pol‐
353 icy settings.
