6 icecast_selinux - Security Enhanced Linux Policy for the icecast pro‐
7 cesses
8
10 Security-Enhanced Linux secures the icecast processes via flexible
11 mandatory access control.
12
13 The icecast processes execute with the icecast_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep icecast_t
20
21
22
24 The icecast_t SELinux type can be entered via the icecast_exec_t file
25 type.
26
27 The default entrypoint paths for the icecast_t domain are the follow‐
28 ing:
29
30 /usr/bin/icecast
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 icecast policy is very flexible allowing users to setup their icecast
40 processes in as secure a method as possible.
41
42 The following process types are defined for icecast:
43
44 icecast_t
45
46 Note: semanage permissive -a icecast_t can be used to make the process
47 type icecast_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. icecast
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run icecast with the tightest access possi‐
56 ble.
57
58
59
60 If you want to determine whether icecast can listen on and connect to
61 any TCP port, you must turn on the icecast_use_any_tcp_ports boolean.
62 Disabled by default.
63
64 setsebool -P icecast_use_any_tcp_ports 1
65
66
67
68 If you want to allow users to resolve user passwd entries directly from
69 ldap rather then using a sssd server, you must turn on the authlo‐
70 gin_nsswitch_use_ldap boolean. Disabled by default.
71
72 setsebool -P authlogin_nsswitch_use_ldap 1
73
74
75
76 If you want to allow all domains to execute in fips_mode, you must turn
77 on the fips_mode boolean. Enabled by default.
78
79 setsebool -P fips_mode 1
80
81
82
83 If you want to allow confined applications to run with kerberos, you
84 must turn on the kerberos_enabled boolean. Enabled by default.
85
86 setsebool -P kerberos_enabled 1
87
88
89
90 If you want to allow system to run with NIS, you must turn on the
91 nis_enabled boolean. Disabled by default.
92
93 setsebool -P nis_enabled 1
94
95
96
97 If you want to allow confined applications to use nscd shared memory,
98 you must turn on the nscd_use_shm boolean. Disabled by default.
99
100 setsebool -P nscd_use_shm 1
101
102
103
105 The SELinux process type icecast_t can manage files labeled with the
106 following file types. The paths listed are the default paths for these
107 file types. Note the processes UID still need to have DAC permissions.

151 SELinux requires files to have an extended attribute to define the file
152 type.
153
154 You can see the context of a file using the -Z option to ls
155
156 Policy governs the access confined processes have to these files.
157 SELinux icecast policy is very flexible allowing users to setup their
158 icecast processes in as secure a method as possible.
159
160 EQUIVALENCE DIRECTORIES
161
162
163 icecast policy stores data with multiple different file context types
164 under the /var/run/icecast directory. If you would like to store the
165 data in a different directory you can use the semanage command to cre‐
166 ate an equivalence mapping. If you wanted to store this data under the
167 /srv dirctory you would execute the following command:
168
169 semanage fcontext -a -e /var/run/icecast /srv/icecast
170 restorecon -R -v /srv/icecast
171
172 STANDARD FILE CONTEXT
173
174 SELinux defines the file context types for the icecast, if you wanted
175 to store files with these types in a diffent paths, you need to execute
176 the semanage command to sepecify alternate labeling and then use
177 restorecon to put the labels on disk.
178
179 semanage fcontext -a -t icecast_var_run_t '/srv/myicecast_con‐
180 tent(/.*)?'
181 restorecon -R -v /srv/myicecast_content
182
183 Note: SELinux often uses regular expressions to specify labels that
184 match multiple files.
185
186 The following file types are defined for icecast:
187
188
189
190 icecast_exec_t
191
192 - Set files with the icecast_exec_t type, if you want to transition an
193 executable to the icecast_t domain.
194
195
196
197 icecast_initrc_exec_t
198
199 - Set files with the icecast_initrc_exec_t type, if you want to transi‐
200 tion an executable to the icecast_initrc_t domain.
201
202
203
204 icecast_log_t
205
206 - Set files with the icecast_log_t type, if you want to treat the data
207 as icecast log data, usually stored under the /var/log directory.
208
209
210
211 icecast_var_run_t
212
213 - Set files with the icecast_var_run_t type, if you want to store the
214 icecast files under the /run or /var/run directory.
215
216
217 Paths:
218 /var/run/icecast(/.*)?, /var/run/icecast.pid
219
220
221 Note: File context can be temporarily modified with the chcon command.
222 If you want to permanently change the file context you need to use the
223 semanage fcontext command. This will modify the SELinux labeling data‐
224 base. You will need to use restorecon to apply the labels.
225
226
228 semanage fcontext can also be used to manipulate default file context
229 mappings.
230
231 semanage permissive can also be used to manipulate whether or not a
232 process type is permissive.
233
234 semanage module can also be used to enable/disable/install/remove pol‐
235 icy modules.
236
237 semanage boolean can also be used to manipulate the booleans
238
239
240 system-config-selinux is a GUI tool available to customize SELinux pol‐
241 icy settings.
