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.
93 cluster_conf_t
95 /etc/cluster(/.*)?
97 cluster_var_lib_t
99 /var/lib/pcsd(/.*)?

131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux ktalkd policy is very flexible allowing users to setup their
138 ktalkd processes in as secure a method as possible.
139 STANDARD FILE CONTEXT
141 SELinux defines the file context types for the ktalkd, if you wanted to
143 store files with these types in a diffent paths, you need to execute
144 the semanage command to sepecify alternate labeling and then use
145 restorecon to put the labels on disk.
146 semanage fcontext -a -t ktalkd_tmp_t '/srv/myktalkd_content(/.*)?'
148 restorecon -R -v /srv/myktalkd_content
149 Note: SELinux often uses regular expressions to specify labels that
151 match multiple files.
152 The following file types are defined for ktalkd:
154 ktalkd_exec_t
158 - Set files with the ktalkd_exec_t type, if you want to transition an
160 executable to the ktalkd_t domain.
161 Paths:
164 /usr/bin/ktalkd, /usr/sbin/ktalkd, /usr/sbin/in.talkd,
165 /usr/sbin/in.ntalkd
166 ktalkd_log_t
169 - Set files with the ktalkd_log_t type, if you want to treat the data
171 as ktalkd log data, usually stored under the /var/log directory.
172 ktalkd_tmp_t
176 - Set files with the ktalkd_tmp_t type, if you want to store ktalkd
178 temporary files in the /tmp directories.
179 ktalkd_unit_file_t
183 - Set files with the ktalkd_unit_file_t type, if you want to treat the
185 files as ktalkd unit content.
186 Note: File context can be temporarily modified with the chcon command.
190 If you want to permanently change the file context you need to use the
191 semanage fcontext command. This will modify the SELinux labeling data‐
192 base. You will need to use restorecon to apply the labels.
193
196 semanage fcontext can also be used to manipulate default file context
197 mappings.
198 semanage permissive can also be used to manipulate whether or not a
200 process type is permissive.
201 semanage module can also be used to enable/disable/install/remove pol‐
203 icy modules.
204 semanage port can also be used to manipulate the port definitions
206 semanage boolean can also be used to manipulate the booleans
208 system-config-selinux is a GUI tool available to customize SELinux pol‐
211 icy settings.
