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 users to resolve user passwd entries directly from
79 ldap rather then using a sssd server, you must turn on the authlo‐
80 gin_nsswitch_use_ldap boolean. Disabled by default.
81 setsebool -P authlogin_nsswitch_use_ldap 1
83 If you want to allow all domains to execute in fips_mode, you must turn
87 on the fips_mode boolean. Enabled by default.
88 setsebool -P fips_mode 1
90 If you want to allow confined applications to run with kerberos, you
94 must turn on the kerberos_enabled boolean. Disabled by default.
95 setsebool -P kerberos_enabled 1
97 If you want to allow system to run with NIS, you must turn on the
101 nis_enabled boolean. Disabled by default.
102 setsebool -P nis_enabled 1
104 If you want to allow confined applications to use nscd shared memory,
108 you must turn on the nscd_use_shm boolean. Disabled by default.
109 setsebool -P nscd_use_shm 1
111
115 SELinux defines port types to represent TCP and UDP ports.
116 You can see the types associated with a port by using the following
118 command:
119 semanage port -l
121 Policy governs the access confined processes have to these ports.
124 SELinux rsync policy is very flexible allowing users to setup their
125 rsync processes in as secure a method as possible.
126 The following port types are defined for rsync:
128 rsync_port_t
131 Default Defined Ports:
135 tcp 873
136 udp 873
137
139 The SELinux process type rsync_t can manage files labeled with the fol‐
140 lowing file types. The paths listed are the default paths for these
141 file types. Note the processes UID still need to have DAC permissions.

241 SELinux requires files to have an extended attribute to define the file
242 type.
243 You can see the context of a file using the -Z option to ls
245 Policy governs the access confined processes have to these files.
247 SELinux rsync policy is very flexible allowing users to setup their
248 rsync processes in as secure a method as possible.
249 STANDARD FILE CONTEXT
251 SELinux defines the file context types for the rsync, if you wanted to
253 store files with these types in a diffent paths, you need to execute
254 the semanage command to sepecify alternate labeling and then use
255 restorecon to put the labels on disk.
256 semanage fcontext -a -t rsync_var_run_t '/srv/myrsync_content(/.*)?'
258 restorecon -R -v /srv/myrsync_content
259 Note: SELinux often uses regular expressions to specify labels that
261 match multiple files.
262 The following file types are defined for rsync:
264 rsync_data_t
268 - Set files with the rsync_data_t type, if you want to treat the files
270 as rsync content.
271 rsync_etc_t
275 - Set files with the rsync_etc_t type, if you want to store rsync files
277 in the /etc directories.
278 rsync_exec_t
282 - Set files with the rsync_exec_t type, if you want to transition an
284 executable to the rsync_t domain.
285 rsync_log_t
289 - Set files with the rsync_log_t type, if you want to treat the data as
291 rsync log data, usually stored under the /var/log directory.
292 rsync_tmp_t
296 - Set files with the rsync_tmp_t type, if you want to store rsync tem‐
298 porary files in the /tmp directories.
299 rsync_var_run_t
303 - Set files with the rsync_var_run_t type, if you want to store the
305 rsync files under the /run or /var/run directory.
306 Paths:
309 /var/run/rsyncd.lock, /var/run/swift_server.lock
310 Note: File context can be temporarily modified with the chcon command.
313 If you want to permanently change the file context you need to use the
314 semanage fcontext command. This will modify the SELinux labeling data‐
315 base. You will need to use restorecon to apply the labels.
316
319 If you want to share files with multiple domains (Apache, FTP, rsync,
320 Samba), you can set a file context of public_content_t and public_con‐
321 tent_rw_t. These context allow any of the above domains to read the
322 content. If you want a particular domain to write to the public_con‐
323 tent_rw_t domain, you must set the appropriate boolean.
324 Allow rsync servers to read the /var/rsync directory by adding the pub‐
326 lic_content_t file type to the directory and by restoring the file
327 type.
328 semanage fcontext -a -t public_content_t "/var/rsync(/.*)?"
330 restorecon -F -R -v /var/rsync
331 Allow rsync servers to read and write /var/rsync/incoming by adding the
333 public_content_rw_t type to the directory and by restoring the file
334 type. You also need to turn on the rsync_anon_write boolean.
335 semanage fcontext -a -t public_content_rw_t "/var/rsync/incoming(/.*)?"
337 restorecon -F -R -v /var/rsync/incoming
338 setsebool -P rsync_anon_write 1
339 If you want to allow rsync to modify public files used for public file
342 transfer services. Files/Directories must be labeled public_con‐
343 tent_rw_t., you must turn on the rsync_anon_write boolean.
344 setsebool -P rsync_anon_write 1
346
349 semanage fcontext can also be used to manipulate default file context
350 mappings.
351 semanage permissive can also be used to manipulate whether or not a
353 process type is permissive.
354 semanage module can also be used to enable/disable/install/remove pol‐
356 icy modules.
357 semanage port can also be used to manipulate the port definitions
359 semanage boolean can also be used to manipulate the booleans
361 system-config-selinux is a GUI tool available to customize SELinux pol‐
364 icy settings.
