6 ktalkd_selinux - Security Enhanced Linux Policy for the ktalkd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the ktalkd processes via flexible
11 mandatory access control.
12
13 The ktalkd processes execute with the ktalkd_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 ktalkd_t
20
21
22
24 The ktalkd_t SELinux type can be entered via the ktalkd_exec_t file
25 type.
26
27 The default entrypoint paths for the ktalkd_t domain are the following:
28
29 /usr/bin/ktalkd, /usr/sbin/ktalkd, /usr/sbin/in.talkd,
30 /usr/sbin/in.ntalkd
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 ktalkd policy is very flexible allowing users to setup their ktalkd
40 processes in as secure a method as possible.
41
42 The following process types are defined for ktalkd:
43
44 ktalkd_t
45
46 Note: semanage permissive -a ktalkd_t can be used to make the process
47 type ktalkd_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. ktalkd
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run ktalkd with the tightest access possible.
56
57
58
59 If you want to allow users to resolve user passwd entries directly from
60 ldap rather then using a sssd server, you must turn on the authlo‐
61 gin_nsswitch_use_ldap boolean. Disabled by default.
62
63 setsebool -P authlogin_nsswitch_use_ldap 1
64
65
66
67 If you want to allow all domains to execute in fips_mode, you must turn
68 on the fips_mode boolean. Enabled by default.
69
70 setsebool -P fips_mode 1
71
72
73
74 If you want to allow confined applications to run with kerberos, you
75 must turn on the kerberos_enabled boolean. Disabled by default.
76
77 setsebool -P kerberos_enabled 1
78
79
80
81 If you want to allow system to run with NIS, you must turn on the
82 nis_enabled boolean. Disabled by default.
83
84 setsebool -P nis_enabled 1
85
86
87
88 If you want to allow confined applications to use nscd shared memory,
89 you must turn on the nscd_use_shm boolean. Disabled by default.
90
91 setsebool -P nscd_use_shm 1
92
93
94
96 SELinux defines port types to represent TCP and UDP ports.
97
98 You can see the types associated with a port by using the following
99 command:
100
101 semanage port -l
102
103
104 Policy governs the access confined processes have to these ports.
105 SELinux ktalkd policy is very flexible allowing users to setup their
106 ktalkd processes in as secure a method as possible.
107
108 The following port types are defined for ktalkd:
109
110
111 ktalkd_port_t
112
113
114
115 Default Defined Ports:
116 udp 517,518
117
119 The SELinux process type ktalkd_t can manage files labeled with the
120 following file types. The paths listed are the default paths for these
121 file types. Note the processes UID still need to have DAC permissions.

163 SELinux requires files to have an extended attribute to define the file
164 type.
165
166 You can see the context of a file using the -Z option to ls
167
168 Policy governs the access confined processes have to these files.
169 SELinux ktalkd policy is very flexible allowing users to setup their
170 ktalkd processes in as secure a method as possible.
171
172 STANDARD FILE CONTEXT
173
174 SELinux defines the file context types for the ktalkd, if you wanted to
175 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 ktalkd_tmp_t '/srv/myktalkd_content(/.*)?'
180 restorecon -R -v /srv/myktalkd_content
181
182 Note: SELinux often uses regular expressions to specify labels that
183 match multiple files.
184
185 The following file types are defined for ktalkd:
186
187
188
189 ktalkd_exec_t
190
191 - Set files with the ktalkd_exec_t type, if you want to transition an
192 executable to the ktalkd_t domain.
193
194
195 Paths:
196 /usr/bin/ktalkd, /usr/sbin/ktalkd, /usr/sbin/in.talkd,
197 /usr/sbin/in.ntalkd
198
199
200 ktalkd_log_t
201
202 - Set files with the ktalkd_log_t type, if you want to treat the data
203 as ktalkd log data, usually stored under the /var/log directory.
204
205
206
207 ktalkd_tmp_t
208
209 - Set files with the ktalkd_tmp_t type, if you want to store ktalkd
210 temporary files in the /tmp directories.
211
212
213
214 ktalkd_unit_file_t
215
216 - Set files with the ktalkd_unit_file_t type, if you want to treat the
217 files as ktalkd unit content.
218
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 port can also be used to manipulate the port definitions
238
239 semanage boolean can also be used to manipulate the booleans
240
241
242 system-config-selinux is a GUI tool available to customize SELinux pol‐
243 icy settings.
