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 to run as a server, you must turn on the
71 rsync_server boolean. Disabled by default.
72 setsebool -P rsync_server 1
74 If you want to allow rsync servers to share cifs files systems, you
78 must turn on the rsync_use_cifs boolean. Disabled by default.
79 setsebool -P rsync_use_cifs 1
81 If you want to allow rsync servers to share nfs files systems, you must
85 turn on the rsync_use_nfs boolean. Disabled by default.
86 setsebool -P rsync_use_nfs 1
88 If you want to allow all domains to use other domains file descriptors,
92 you must turn on the allow_domain_fd_use boolean. Enabled by default.
93 setsebool -P allow_domain_fd_use 1
95 If you want to allow confined applications to run with kerberos, you
99 must turn on the allow_kerberos boolean. Enabled by default.
100 setsebool -P allow_kerberos 1
102 If you want to allow sysadm to debug or ptrace all processes, you must
106 turn on the allow_ptrace boolean. Disabled by default.
107 setsebool -P allow_ptrace 1
109 If you want to allow system to run with NIS, you must turn on the
113 allow_ypbind boolean. Disabled by default.
114 setsebool -P allow_ypbind 1
116 If you want to allow all domains to have the kernel load modules, you
120 must turn on the domain_kernel_load_modules boolean. Disabled by
121 default.
122 setsebool -P domain_kernel_load_modules 1
124 If you want to allow all domains to execute in fips_mode, you must turn
128 on the fips_mode boolean. Enabled by default.
129 setsebool -P fips_mode 1
131 If you want to enable reading of urandom for all domains, you must turn
135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1
138 If you want to allow confined applications to use nscd shared memory,
142 you must turn on the nscd_use_shm boolean. Enabled by default.
143 setsebool -P nscd_use_shm 1
145
149 SELinux defines port types to represent TCP and UDP ports.
150 You can see the types associated with a port by using the following
152 command:
153 semanage port -l
155 Policy governs the access confined processes have to these ports.
158 SELinux rsync policy is very flexible allowing users to setup their
159 rsync processes in as secure a method as possible.
160 The following port types are defined for rsync:
162 rsync_port_t
165 Default Defined Ports:
169 tcp 873
170 udp 873
171
173 The SELinux process type rsync_t can manage files labeled with the fol‐
174 lowing file types. The paths listed are the default paths for these
175 file types. Note the processes UID still need to have DAC permissions.

238 SELinux requires files to have an extended attribute to define the file
239 type.
240 You can see the context of a file using the -Z option to ls
242 Policy governs the access confined processes have to these files.
244 SELinux rsync policy is very flexible allowing users to setup their
245 rsync processes in as secure a method as possible.
246 STANDARD FILE CONTEXT
248 SELinux defines the file context types for the rsync, if you wanted to
250 store files with these types in a diffent paths, you need to execute
251 the semanage command to sepecify alternate labeling and then use
252 restorecon to put the labels on disk.
253 semanage fcontext -a -t rsync_var_run_t '/srv/myrsync_content(/.*)?'
255 restorecon -R -v /srv/myrsync_content
256 Note: SELinux often uses regular expressions to specify labels that
258 match multiple files.
259 The following file types are defined for rsync:
261 rsync_data_t
265 - Set files with the rsync_data_t type, if you want to treat the files
267 as rsync content.
268 rsync_etc_t
272 - Set files with the rsync_etc_t type, if you want to store rsync files
274 in the /etc directories.
275 rsync_exec_t
279 - Set files with the rsync_exec_t type, if you want to transition an
281 executable to the rsync_t domain.
282 rsync_log_t
286 - Set files with the rsync_log_t type, if you want to treat the data as
288 rsync log data, usually stored under the /var/log directory.
289 rsync_tmp_t
293 - Set files with the rsync_tmp_t type, if you want to store rsync tem‐
295 porary files in the /tmp directories.
296 rsync_var_run_t
300 - Set files with the rsync_var_run_t type, if you want to store the
302 rsync files under the /run or /var/run directory.
303 Note: File context can be temporarily modified with the chcon command.
307 If you want to permanently change the file context you need to use the
308 semanage fcontext command. This will modify the SELinux labeling data‐
309 base. You will need to use restorecon to apply the labels.
310
313 If you want to share files with multiple domains (Apache, FTP, rsync,
314 Samba), you can set a file context of public_content_t and public_con‐
315 tent_rw_t. These context allow any of the above domains to read the
316 content. If you want a particular domain to write to the public_con‐
317 tent_rw_t domain, you must set the appropriate boolean.
318 Allow rsync servers to read the /var/rsync directory by adding the pub‐
320 lic_content_t file type to the directory and by restoring the file
321 type.
322 semanage fcontext -a -t public_content_t "/var/rsync(/.*)?"
324 restorecon -F -R -v /var/rsync
325 Allow rsync servers to read and write /var/rsync/incoming by adding the
327 public_content_rw_t type to the directory and by restoring the file
328 type. You also need to turn on the rsync_anon_write boolean.
329 semanage fcontext -a -t public_content_rw_t "/var/rsync/incoming(/.*)?"
331 restorecon -F -R -v /var/rsync/incoming
332 setsebool -P rsync_anon_write 1
333 If you want to allow rsync to modify public files used for public file
336 transfer services. Files/Directories must be labeled public_con‐
337 tent_rw_t., you must turn on the allow_rsync_anon_write boolean.
338 setsebool -P allow_rsync_anon_write 1
340
343 semanage fcontext can also be used to manipulate default file context
344 mappings.
345 semanage permissive can also be used to manipulate whether or not a
347 process type is permissive.
348 semanage module can also be used to enable/disable/install/remove pol‐
350 icy modules.
351 semanage port can also be used to manipulate the port definitions
353 semanage boolean can also be used to manipulate the booleans
355 system-config-selinux is a GUI tool available to customize SELinux pol‐
358 icy settings.
