6 lsmd_selinux - Security Enhanced Linux Policy for the lsmd processes
7
9 Security-Enhanced Linux secures the lsmd processes via flexible manda‐
10 tory access control.
11 The lsmd processes execute with the lsmd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15 For example:
17 ps -eZ | grep lsmd_t
19
23 The lsmd_t SELinux type can be entered via the lsmd_exec_t file type.
24 The default entrypoint paths for the lsmd_t domain are the following:
26 /usr/bin/lsmd
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 lsmd policy is very flexible allowing users to setup their lsmd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for lsmd:
40 lsmd_t, lsmd_plugin_t
42 Note: semanage permissive -a lsmd_t can be used to make the process
44 type lsmd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. lsmd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run lsmd with the tightest access possible.
53 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58 setsebool -P fips_mode 1
60 If you want to allow system to run with NIS, you must turn on the
64 nis_enabled boolean. Disabled by default.
65 setsebool -P nis_enabled 1
67
71 SELinux defines port types to represent TCP and UDP ports.
72 You can see the types associated with a port by using the following
74 command:
75 semanage port -l
77 Policy governs the access confined processes have to these ports.
80 SELinux lsmd policy is very flexible allowing users to setup their lsmd
81 processes in as secure a method as possible.
82 The following port types are defined for lsmd:
84 lsm_plugin_port_t
87 Default Defined Ports:
91 tcp 18700
92
94 The SELinux process type lsmd_t can manage files labeled with the fol‐
95 lowing file types. The paths listed are the default paths for these
96 file types. Note the processes UID still need to have DAC permissions.

139 SELinux requires files to have an extended attribute to define the file
140 type.
141 You can see the context of a file using the -Z option to ls
143 Policy governs the access confined processes have to these files.
145 SELinux lsmd policy is very flexible allowing users to setup their lsmd
146 processes in as secure a method as possible.
147 STANDARD FILE CONTEXT
149 SELinux defines the file context types for the lsmd, if you wanted to
151 store files with these types in a diffent paths, you need to execute
152 the semanage command to sepecify alternate labeling and then use
153 restorecon to put the labels on disk.
154 semanage fcontext -a -t lsmd_plugin_tmp_t '/srv/mylsmd_content(/.*)?'
156 restorecon -R -v /srv/mylsmd_content
157 Note: SELinux often uses regular expressions to specify labels that
159 match multiple files.
160 The following file types are defined for lsmd:
162 lsmd_exec_t
166 - Set files with the lsmd_exec_t type, if you want to transition an
168 executable to the lsmd_t domain.
169 lsmd_plugin_exec_t
173 - Set files with the lsmd_plugin_exec_t type, if you want to transition
175 an executable to the lsmd_plugin_t domain.
176 lsmd_plugin_tmp_t
180 - Set files with the lsmd_plugin_tmp_t type, if you want to store lsmd
182 plugin temporary files in the /tmp directories.
183 lsmd_unit_file_t
187 - Set files with the lsmd_unit_file_t type, if you want to treat the
189 files as lsmd unit content.
190 lsmd_var_run_t
194 - Set files with the lsmd_var_run_t type, if you want to store the lsmd
196 files under the /run or /var/run directory.
197 Note: File context can be temporarily modified with the chcon command.
201 If you want to permanently change the file context you need to use the
202 semanage fcontext command. This will modify the SELinux labeling data‐
203 base. You will need to use restorecon to apply the labels.
204
207 semanage fcontext can also be used to manipulate default file context
208 mappings.
209 semanage permissive can also be used to manipulate whether or not a
211 process type is permissive.
212 semanage module can also be used to enable/disable/install/remove pol‐
214 icy modules.
215 semanage port can also be used to manipulate the port definitions
217 semanage boolean can also be used to manipulate the booleans
219 system-config-selinux is a GUI tool available to customize SELinux pol‐
222 icy settings.
