6 jabberd_selinux - Security Enhanced Linux Policy for the jabberd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the jabberd processes via flexible
11 mandatory access control.
12 The jabberd processes execute with the jabberd_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16 For example:
18 ps -eZ | grep jabberd_t
20
24 The jabberd_t SELinux type can be entered via the jabberd_exec_t file
25 type.
26 The default entrypoint paths for the jabberd_t domain are the follow‐
28 ing:
29 /usr/bin/sm, /usr/bin/s2s
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 jabberd policy is very flexible allowing users to setup their jabberd
40 processes in as secure a method as possible.
41 The following process types are defined for jabberd:
43 jabberd_t, jabberd_router_t
45 Note: semanage permissive -a jabberd_t can be used to make the process
47 type jabberd_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. jabberd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run jabberd with the tightest access possi‐
56 ble.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the daemons_dump_core boolean. Disabled by default.
62 setsebool -P daemons_dump_core 1

68 daemons_enable_cluster_mode boolean. Enabled by default.

135 on the global_ssp boolean. Disabled by default.
136 setsebool -P global_ssp 1

142 SELinux defines port types to represent TCP and UDP ports.
143 You can see the types associated with a port by using the following
145 command:
146 semanage port -l
148 Policy governs the access confined processes have to these ports.
151 SELinux jabberd policy is very flexible allowing users to setup their
152 jabberd processes in as secure a method as possible.
153 The following port types are defined for jabberd:
155 jabber_client_port_t
158 Default Defined Ports:
162 tcp 5222,5223
163 jabber_interserver_port_t
166 Default Defined Ports:
170 tcp 5269,5280
171 jabber_router_port_t
174 Default Defined Ports:
178 tcp 5347
179
181 The SELinux process type jabberd_t can manage files labeled with the
182 following file types. The paths listed are the default paths for these
183 file types. Note the processes UID still need to have DAC permissions.
184 cluster_conf_t
186 /etc/cluster(/.*)?
188 cluster_var_lib_t
190 /var/lib/pcsd(/.*)?
192 /var/lib/cluster(/.*)?

226 SELinux requires files to have an extended attribute to define the file
227 type.
228 You can see the context of a file using the -Z option to ls
230 Policy governs the access confined processes have to these files.
232 SELinux jabberd policy is very flexible allowing users to setup their
233 jabberd processes in as secure a method as possible.
234 STANDARD FILE CONTEXT
236 SELinux defines the file context types for the jabberd, if you wanted
238 to store files with these types in a diffent paths, you need to execute
239 the semanage command to sepecify alternate labeling and then use
240 restorecon to put the labels on disk.
241 semanage fcontext -a -t jabberd_var_lib_t '/srv/myjabberd_con‐
243 tent(/.*)?'
244 restorecon -R -v /srv/myjabberd_content
245 Note: SELinux often uses regular expressions to specify labels that
247 match multiple files.
248 The following file types are defined for jabberd:
250 jabberd_exec_t
254 - Set files with the jabberd_exec_t type, if you want to transition an
256 executable to the jabberd_t domain.
257 Paths:
260 /usr/bin/sm, /usr/bin/s2s
261 jabberd_initrc_exec_t
264 - Set files with the jabberd_initrc_exec_t type, if you want to transi‐
266 tion an executable to the jabberd_initrc_t domain.
267 jabberd_router_exec_t
271 - Set files with the jabberd_router_exec_t type, if you want to transi‐
273 tion an executable to the jabberd_router_t domain.
274 Paths:
277 /usr/bin/c2s, /usr/bin/router
278 jabberd_var_lib_t
281 - Set files with the jabberd_var_lib_t type, if you want to store the
283 jabberd files under the /var/lib directory.
284 Note: File context can be temporarily modified with the chcon command.
288 If you want to permanently change the file context you need to use the
289 semanage fcontext command. This will modify the SELinux labeling data‐
290 base. You will need to use restorecon to apply the labels.
291
294 semanage fcontext can also be used to manipulate default file context
295 mappings.
296 semanage permissive can also be used to manipulate whether or not a
298 process type is permissive.
299 semanage module can also be used to enable/disable/install/remove pol‐
301 icy modules.
302 semanage port can also be used to manipulate the port definitions
304 semanage boolean can also be used to manipulate the booleans
306 system-config-selinux is a GUI tool available to customize SELinux pol‐
309 icy settings.
