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, /usr/sbin/jabberd
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_router_t, jabberd_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 allow_daemons_dump_core boolean. Disabled by default.
62 setsebool -P allow_daemons_dump_core 1
64 If you want to allow all daemons to use tcp wrappers, you must turn on
68 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
69 setsebool -P allow_daemons_use_tcp_wrapper 1
71 If you want to allow all daemons the ability to read/write terminals,
75 you must turn on the allow_daemons_use_tty boolean. Disabled by
76 default.
77 setsebool -P allow_daemons_use_tty 1
79 If you want to allow all domains to use other domains file descriptors,
83 you must turn on the allow_domain_fd_use boolean. Enabled by default.
84 setsebool -P allow_domain_fd_use 1

90 turn on the allow_ptrace boolean. Disabled by default.
91 setsebool -P allow_ptrace 1

104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1
129
133 SELinux defines port types to represent TCP and UDP ports.
134 You can see the types associated with a port by using the following
136 command:
137 semanage port -l
139 Policy governs the access confined processes have to these ports.
142 SELinux jabberd policy is very flexible allowing users to setup their
143 jabberd processes in as secure a method as possible.
144 The following port types are defined for jabberd:
146 jabber_client_port_t
149 Default Defined Ports:
153 tcp 5222,5223
154 jabber_interserver_port_t
157 Default Defined Ports:
161 tcp 5269
162 jabber_router_port_t
165 Default Defined Ports:
169 tcp 5347
170
172 The SELinux process type jabberd_t can manage files labeled with the
173 following file types. The paths listed are the default paths for these
174 file types. Note the processes UID still need to have DAC permissions.
175 cluster_conf_t

247 SELinux requires files to have an extended attribute to define the file
248 type.
249 You can see the context of a file using the -Z option to ls
251 Policy governs the access confined processes have to these files.
253 SELinux jabberd policy is very flexible allowing users to setup their
254 jabberd processes in as secure a method as possible.
255 EQUIVALENCE DIRECTORIES
257 jabberd policy stores data with multiple different file context types
260 under the /var/lib/jabber directory. If you would like to store the
261 data in a different directory you can use the semanage command to cre‐
262 ate an equivalence mapping. If you wanted to store this data under the
263 /srv dirctory you would execute the following command:
264 semanage fcontext -a -e /var/lib/jabber /srv/jabber
266 restorecon -R -v /srv/jabber
267 STANDARD FILE CONTEXT
269 SELinux defines the file context types for the jabberd, if you wanted
271 to store files with these types in a diffent paths, you need to execute
272 the semanage command to sepecify alternate labeling and then use
273 restorecon to put the labels on disk.
274 semanage fcontext -a -t jabberd_var_run_t '/srv/myjabberd_con‐
276 tent(/.*)?'
277 restorecon -R -v /srv/myjabberd_content
278 Note: SELinux often uses regular expressions to specify labels that
280 match multiple files.
281 The following file types are defined for jabberd:
283 jabberd_exec_t
287 - Set files with the jabberd_exec_t type, if you want to transition an
289 executable to the jabberd_t domain.
290 Paths:
293 /usr/bin/sm, /usr/bin/s2s, /usr/sbin/jabberd
294 jabberd_initrc_exec_t
297 - Set files with the jabberd_initrc_exec_t type, if you want to transi‐
299 tion an executable to the jabberd_initrc_t domain.
300 jabberd_log_t
304 - Set files with the jabberd_log_t type, if you want to treat the data
306 as jabberd log data, usually stored under the /var/log directory.
307 jabberd_router_exec_t
311 - Set files with the jabberd_router_exec_t type, if you want to transi‐
313 tion an executable to the jabberd_router_t domain.
314 Paths:
317 /usr/bin/c2s, /usr/bin/router
318 jabberd_var_lib_t
321 - Set files with the jabberd_var_lib_t type, if you want to store the
323 jabberd files under the /var/lib directory.
324 Paths:
327 /var/lib/jabber(/.*)?, /var/lib/jabberd(/.*)?
328 jabberd_var_run_t
331 - Set files with the jabberd_var_run_t type, if you want to store the
333 jabberd files under the /run or /var/run directory.
334 Note: File context can be temporarily modified with the chcon command.
338 If you want to permanently change the file context you need to use the
339 semanage fcontext command. This will modify the SELinux labeling data‐
340 base. You will need to use restorecon to apply the labels.
341
344 semanage fcontext can also be used to manipulate default file context
345 mappings.
346 semanage permissive can also be used to manipulate whether or not a
348 process type is permissive.
349 semanage module can also be used to enable/disable/install/remove pol‐
351 icy modules.
352 semanage port can also be used to manipulate the port definitions
354 semanage boolean can also be used to manipulate the booleans
356 system-config-selinux is a GUI tool available to customize SELinux pol‐
359 icy settings.
