6 irc_selinux - Security Enhanced Linux Policy for the irc processes
7
9 Security-Enhanced Linux secures the irc processes via flexible manda‐
10 tory access control.
11 The irc processes execute with the irc_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15 For example:
17 ps -eZ | grep irc_t
19
23 The irc_t SELinux type can be entered via the irc_exec_t file type.
24 The default entrypoint paths for the irc_t domain are the following:
26 /usr/bin/[st]irc, /usr/bin/ircII, /usr/bin/irssi, /usr/bin/tinyirc
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 irc policy is very flexible allowing users to setup their irc processes
37 in as secure a method as possible.
38 The following process types are defined for irc:
40 irc_t
42 Note: semanage permissive -a irc_t can be used to make the process type
44 irc_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
49 SELinux policy is customizable based on least access required. irc
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run irc with the tightest access possible.
52 If you want to determine whether irc clients can listen on and connect
56 to any unreserved TCP ports, you must turn on the irc_use_any_tcp_ports
57 boolean. Disabled by default.
58 setsebool -P irc_use_any_tcp_ports 1
60 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65 setsebool -P fips_mode 1
67 If you want to allow system to run with NIS, you must turn on the
71 nis_enabled boolean. Disabled by default.
72 setsebool -P nis_enabled 1
74
78 SELinux defines port types to represent TCP and UDP ports.
79 You can see the types associated with a port by using the following
81 command:
82 semanage port -l
84 Policy governs the access confined processes have to these ports.
87 SELinux irc policy is very flexible allowing users to setup their irc
88 processes in as secure a method as possible.
89 The following port types are defined for irc:
91 ircd_port_t
94 Default Defined Ports:
98 tcp 6667,6697
99
101 The SELinux process type irc_t can manage files labeled with the fol‐
102 lowing file types. The paths listed are the default paths for these
103 file types. Note the processes UID still need to have DAC permissions.

149 SELinux requires files to have an extended attribute to define the file
150 type.
151 You can see the context of a file using the -Z option to ls
153 Policy governs the access confined processes have to these files.
155 SELinux irc policy is very flexible allowing users to setup their irc
156 processes in as secure a method as possible.
157 STANDARD FILE CONTEXT
159 SELinux defines the file context types for the irc, if you wanted to
161 store files with these types in a different paths, you need to execute
162 the semanage command to specify alternate labeling and then use re‐
163 storecon to put the labels on disk.
164 semanage fcontext -a -t irc_exec_t '/srv/irc/content(/.*)?'
166 restorecon -R -v /srv/myirc_content
167 Note: SELinux often uses regular expressions to specify labels that
169 match multiple files.
170 The following file types are defined for irc:
172 irc_conf_t
176 - Set files with the irc_conf_t type, if you want to treat the files as
178 irc configuration data, usually stored under the /etc directory.
179 irc_exec_t
183 - Set files with the irc_exec_t type, if you want to transition an exe‐
185 cutable to the irc_t domain.
186 Paths:
189 /usr/bin/[st]irc, /usr/bin/ircII, /usr/bin/irssi, /usr/bin/tinyirc
190 irc_home_t
193 - Set files with the irc_home_t type, if you want to store irc files in
195 the users home directory.
196 Paths:
199 /home/[^/]+/.irssi(/.*)?, /home/[^/]+/irclog(/.*)?,
200 /home/[^/]+/.ircmotd
201 irc_tmp_t
204 - Set files with the irc_tmp_t type, if you want to store irc temporary
206 files in the /tmp directories.
207 Note: File context can be temporarily modified with the chcon command.
211 If you want to permanently change the file context you need to use the
212 semanage fcontext command. This will modify the SELinux labeling data‐
213 base. You will need to use restorecon to apply the labels.
214
217 semanage fcontext can also be used to manipulate default file context
218 mappings.
219 semanage permissive can also be used to manipulate whether or not a
221 process type is permissive.
222 semanage module can also be used to enable/disable/install/remove pol‐
224 icy modules.
225 semanage port can also be used to manipulate the port definitions
227 semanage boolean can also be used to manipulate the booleans
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
