6 ctdbd_selinux - Security Enhanced Linux Policy for the ctdbd processes
7
9 Security-Enhanced Linux secures the ctdbd processes via flexible manda‐
10 tory access control.
11 The ctdbd processes execute with the ctdbd_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 ctdbd_t
19
23 The ctdbd_t SELinux type can be entered via the ctdbd_exec_t file type.
24 The default entrypoint paths for the ctdbd_t domain are the following:
26 /etc/ctdb/events.d/.*, /usr/sbin/ctdbd, /usr/sbin/ctdbd_wrapper
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 ctdbd policy is very flexible allowing users to setup their ctdbd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for ctdbd:
40 ctdbd_t
42 Note: semanage permissive -a ctdbd_t can be used to make the process
44 type ctdbd_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. ctdbd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run ctdbd with the tightest access possible.
53 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60
64 SELinux defines port types to represent TCP and UDP ports.
65 You can see the types associated with a port by using the following
67 command:
68 semanage port -l
70 Policy governs the access confined processes have to these ports.
73 SELinux ctdbd policy is very flexible allowing users to setup their
74 ctdbd processes in as secure a method as possible.
75 The following port types are defined for ctdbd:
77 ctdb_port_t
80 Default Defined Ports:
84 tcp 4379
85 udp 4379
86
88 The SELinux process type ctdbd_t can manage files labeled with the fol‐
89 lowing file types. The paths listed are the default paths for these
90 file types. Note the processes UID still need to have DAC permissions.

173 SELinux requires files to have an extended attribute to define the file
174 type.
175 You can see the context of a file using the -Z option to ls
177 Policy governs the access confined processes have to these files.
179 SELinux ctdbd policy is very flexible allowing users to setup their
180 ctdbd processes in as secure a method as possible.
181 EQUIVALENCE DIRECTORIES
183 ctdbd policy stores data with multiple different file context types
186 under the /var/lib/ctdb directory. If you would like to store the data
187 in a different directory you can use the semanage command to create an
188 equivalence mapping. If you wanted to store this data under the /srv
189 directory you would execute the following command:
190 semanage fcontext -a -e /var/lib/ctdb /srv/ctdb
192 restorecon -R -v /srv/ctdb
193 ctdbd policy stores data with multiple different file context types
195 under the /var/run/ctdb directory. If you would like to store the data
196 in a different directory you can use the semanage command to create an
197 equivalence mapping. If you wanted to store this data under the /srv
198 directory you would execute the following command:
199 semanage fcontext -a -e /var/run/ctdb /srv/ctdb
201 restorecon -R -v /srv/ctdb
202 STANDARD FILE CONTEXT
204 SELinux defines the file context types for the ctdbd, if you wanted to
206 store files with these types in a diffent paths, you need to execute
207 the semanage command to sepecify alternate labeling and then use
208 restorecon to put the labels on disk.
209 semanage fcontext -a -t ctdbd_var_run_t '/srv/myctdbd_content(/.*)?'
211 restorecon -R -v /srv/myctdbd_content
212 Note: SELinux often uses regular expressions to specify labels that
214 match multiple files.
215 The following file types are defined for ctdbd:
217 ctdbd_exec_t
221 - Set files with the ctdbd_exec_t type, if you want to transition an
223 executable to the ctdbd_t domain.
224 Paths:
227 /etc/ctdb/events.d/.*, /usr/sbin/ctdbd, /usr/sbin/ctdbd_wrapper
228 ctdbd_initrc_exec_t
231 - Set files with the ctdbd_initrc_exec_t type, if you want to transi‐
233 tion an executable to the ctdbd_initrc_t domain.
234 ctdbd_log_t
238 - Set files with the ctdbd_log_t type, if you want to treat the data as
240 ctdbd log data, usually stored under the /var/log directory.
241 Paths:
244 /var/log/ctdb.log.*, /var/log/log.ctdb.*
245 ctdbd_spool_t
248 - Set files with the ctdbd_spool_t type, if you want to store the ctdbd
250 files under the /var/spool directory.
251 ctdbd_tmp_t
255 - Set files with the ctdbd_tmp_t type, if you want to store ctdbd tem‐
257 porary files in the /tmp directories.
258 ctdbd_var_lib_t
262 - Set files with the ctdbd_var_lib_t type, if you want to store the
264 ctdbd files under the /var/lib directory.
265 Paths:
268 /var/lib/ctdb(/.*)?, /var/lib/ctdbd(/.*)?
269 ctdbd_var_run_t
272 - Set files with the ctdbd_var_run_t type, if you want to store the
274 ctdbd files under the /run or /var/run directory.
275 Paths:
278 /var/run/ctdb(/.*)?, /var/run/ctdbd(/.*)?
279 ctdbd_var_t
282 - Set files with the ctdbd_var_t type, if you want to store the c files
284 under the /var directory.
285 Note: File context can be temporarily modified with the chcon command.
289 If you want to permanently change the file context you need to use the
290 semanage fcontext command. This will modify the SELinux labeling data‐
291 base. You will need to use restorecon to apply the labels.
292
295 semanage fcontext can also be used to manipulate default file context
296 mappings.
297 semanage permissive can also be used to manipulate whether or not a
299 process type is permissive.
300 semanage module can also be used to enable/disable/install/remove pol‐
302 icy modules.
303 semanage port can also be used to manipulate the port definitions
305 semanage boolean can also be used to manipulate the booleans
307 system-config-selinux is a GUI tool available to customize SELinux pol‐
310 icy settings.
