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 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 For example:
18 ps -eZ | grep icecast_t
20
24 The icecast_t SELinux type can be entered via the icecast_exec_t file
25 type.
26 The default entrypoint paths for the icecast_t domain are the follow‐
28 ing:
29 /usr/bin/icecast
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 icecast policy is very flexible allowing users to setup their icecast
40 processes in as secure a method as possible.
41 The following process types are defined for icecast:
43 icecast_t
45 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
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 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 setsebool -P icecast_use_any_tcp_ports 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72
76 The SELinux process type icecast_t can manage files labeled with the
77 following file types. The paths listed are the default paths for these
78 file types. Note the processes UID still need to have DAC permissions.

122 SELinux requires files to have an extended attribute to define the file
123 type.
124 You can see the context of a file using the -Z option to ls
126 Policy governs the access confined processes have to these files.
128 SELinux icecast policy is very flexible allowing users to setup their
129 icecast processes in as secure a method as possible.
130 EQUIVALENCE DIRECTORIES
132 icecast policy stores data with multiple different file context types
135 under the /var/run/icecast directory. If you would like to store the
136 data in a different directory you can use the semanage command to cre‐
137 ate an equivalence mapping. If you wanted to store this data under the
138 /srv directory you would execute the following command:
139 semanage fcontext -a -e /var/run/icecast /srv/icecast
141 restorecon -R -v /srv/icecast
142 STANDARD FILE CONTEXT
144 SELinux defines the file context types for the icecast, if you wanted
146 to store files with these types in a diffent paths, you need to execute
147 the semanage command to sepecify alternate labeling and then use
148 restorecon to put the labels on disk.
149 semanage fcontext -a -t icecast_var_run_t '/srv/myicecast_con‐
151 tent(/.*)?'
152 restorecon -R -v /srv/myicecast_content
153 Note: SELinux often uses regular expressions to specify labels that
155 match multiple files.
156 The following file types are defined for icecast:
158 icecast_exec_t
162 - Set files with the icecast_exec_t type, if you want to transition an
164 executable to the icecast_t domain.
165 icecast_initrc_exec_t
169 - Set files with the icecast_initrc_exec_t type, if you want to transi‐
171 tion an executable to the icecast_initrc_t domain.
172 icecast_log_t
176 - Set files with the icecast_log_t type, if you want to treat the data
178 as icecast log data, usually stored under the /var/log directory.
179 icecast_var_run_t
183 - Set files with the icecast_var_run_t type, if you want to store the
185 icecast files under the /run or /var/run directory.
186 Paths:
189 /var/run/icecast(/.*)?, /var/run/icecast.pid
190 Note: File context can be temporarily modified with the chcon command.
193 If you want to permanently change the file context you need to use the
194 semanage fcontext command. This will modify the SELinux labeling data‐
195 base. You will need to use restorecon to apply the labels.
196
199 semanage fcontext can also be used to manipulate default file context
200 mappings.
201 semanage permissive can also be used to manipulate whether or not a
203 process type is permissive.
204 semanage module can also be used to enable/disable/install/remove pol‐
206 icy modules.
207 semanage boolean can also be used to manipulate the booleans
209 system-config-selinux is a GUI tool available to customize SELinux pol‐
212 icy settings.
