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 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 For example:
18 ps -eZ | grep ktalkd_t
20
24 The ktalkd_t SELinux type can be entered via the ktalkd_exec_t file
25 type.
26 The default entrypoint paths for the ktalkd_t domain are the following:
28 /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 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 ktalkd policy is very flexible allowing users to setup their ktalkd
40 processes in as secure a method as possible.
41 The following process types are defined for ktalkd:
43 ktalkd_t
45 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
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 If you want to allow all domains to execute in fips_mode, you must turn
60 on the fips_mode boolean. Enabled by default.
61 setsebool -P fips_mode 1
63
67 SELinux defines port types to represent TCP and UDP ports.
68 You can see the types associated with a port by using the following
70 command:
71 semanage port -l
73 Policy governs the access confined processes have to these ports.
76 SELinux ktalkd policy is very flexible allowing users to setup their
77 ktalkd processes in as secure a method as possible.
78 The following port types are defined for ktalkd:
80 ktalkd_port_t
83 Default Defined Ports:
87 udp 517,518
88
90 The SELinux process type ktalkd_t can manage files labeled with the
91 following file types. The paths listed are the default paths for these
92 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 ktalkd policy is very flexible allowing users to setup their
156 ktalkd processes in as secure a method as possible.
157 STANDARD FILE CONTEXT
159 SELinux defines the file context types for the ktalkd, if you wanted to
161 store files with these types in a diffent 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 ktalkd_tmp_t '/srv/myktalkd_content(/.*)?'
166 restorecon -R -v /srv/myktalkd_content
167 Note: SELinux often uses regular expressions to specify labels that
169 match multiple files.
170 The following file types are defined for ktalkd:
172 ktalkd_exec_t
176 - Set files with the ktalkd_exec_t type, if you want to transition an
178 executable to the ktalkd_t domain.
179 Paths:
182 /usr/bin/ktalkd, /usr/sbin/ktalkd, /usr/sbin/in.talkd,
183 /usr/sbin/in.ntalkd
184 ktalkd_log_t
187 - Set files with the ktalkd_log_t type, if you want to treat the data
189 as ktalkd log data, usually stored under the /var/log directory.
190 ktalkd_tmp_t
194 - Set files with the ktalkd_tmp_t type, if you want to store ktalkd
196 temporary files in the /tmp directories.
197 ktalkd_unit_file_t
201 - Set files with the ktalkd_unit_file_t type, if you want to treat the
203 files as ktalkd unit content.
204 Note: File context can be temporarily modified with the chcon command.
208 If you want to permanently change the file context you need to use the
209 semanage fcontext command. This will modify the SELinux labeling data‐
210 base. You will need to use restorecon to apply the labels.
211
214 semanage fcontext can also be used to manipulate default file context
215 mappings.
216 semanage permissive can also be used to manipulate whether or not a
218 process type is permissive.
219 semanage module can also be used to enable/disable/install/remove pol‐
221 icy modules.
222 semanage port can also be used to manipulate the port definitions
224 semanage boolean can also be used to manipulate the booleans
226 system-config-selinux is a GUI tool available to customize SELinux pol‐
229 icy settings.
