6 lsmd_plugin_selinux - Security Enhanced Linux Policy for the lsmd_plug‐
7 in processes
8
10 Security-Enhanced Linux secures the lsmd_plugin processes via flexible
11 mandatory access control.
12
13 The lsmd_plugin processes execute with the lsmd_plugin_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep lsmd_plugin_t
20
21
22
24 The lsmd_plugin_t SELinux type can be entered via the lsmd_plug‐
25 in_exec_t file type.
26
27 The default entrypoint paths for the lsmd_plugin_t domain are the fol‐
28 lowing:
29
30 /usr/bin/.*_lsmplugin
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 lsmd_plugin policy is very flexible allowing users to setup their
40 lsmd_plugin processes in as secure a method as possible.
41
42 The following process types are defined for lsmd_plugin:
43
44 lsmd_plugin_t
45
46 Note: semanage permissive -a lsmd_plugin_t can be used to make the
47 process type lsmd_plugin_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 lsmd_plugin policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run lsmd_plugin with the tight‐
56 est access possible.
57
58
59
60 If you want to determine whether lsmd_plugin can connect to all TCP
61 ports, you must turn on the lsmd_plugin_connect_any boolean. Disabled
62 by default.
63
64 setsebool -P lsmd_plugin_connect_any 1
65
66
67
68 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70
71 setsebool -P allow_domain_fd_use 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the allow_kerberos boolean. Enabled by default.
77
78 setsebool -P allow_kerberos 1
79
80
81
82 If you want to allow sysadm to debug or ptrace all processes, you must
83 turn on the allow_ptrace boolean. Disabled by default.
84
85 setsebool -P allow_ptrace 1
86
87
88
89 If you want to allow system to run with NIS, you must turn on the
90 allow_ypbind boolean. Disabled by default.
91
92 setsebool -P allow_ypbind 1
93
94
95
96 If you want to allow all domains to have the kernel load modules, you
97 must turn on the domain_kernel_load_modules boolean. Disabled by
98 default.
99
100 setsebool -P domain_kernel_load_modules 1
101
102
103
104 If you want to allow all domains to execute in fips_mode, you must turn
105 on the fips_mode boolean. Enabled by default.
106
107 setsebool -P fips_mode 1
108
109
110
111 If you want to enable reading of urandom for all domains, you must turn
112 on the global_ssp boolean. Disabled by default.
113
114 setsebool -P global_ssp 1
115
116
117
118 If you want to allow confined applications to use nscd shared memory,
119 you must turn on the nscd_use_shm boolean. Enabled by default.
120
121 setsebool -P nscd_use_shm 1
122
123
124
126 The SELinux process type lsmd_plugin_t can manage files labeled with
127 the following file types. The paths listed are the default paths for
128 these file types. Note the processes UID still need to have DAC per‐
129 missions.

162 SELinux requires files to have an extended attribute to define the file
163 type.
164
165 You can see the context of a file using the -Z option to ls
166
167 Policy governs the access confined processes have to these files.
168 SELinux lsmd_plugin policy is very flexible allowing users to setup
169 their lsmd_plugin processes in as secure a method as possible.
170
171 STANDARD FILE CONTEXT
172
173 SELinux defines the file context types for the lsmd_plugin, if you
174 wanted to store files with these types in a diffent paths, you need to
175 execute the semanage command to sepecify alternate labeling and then
176 use restorecon to put the labels on disk.
177
178 semanage fcontext -a -t lsmd_plugin_tmp_t '/srv/mylsmd_plugin_con‐
179 tent(/.*)?'
180 restorecon -R -v /srv/mylsmd_plugin_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 lsmd_plugin:
186
187
188
189 lsmd_plugin_exec_t
190
191 - Set files with the lsmd_plugin_exec_t type, if you want to transition
192 an executable to the lsmd_plugin_t domain.
193
194
195
196 lsmd_plugin_tmp_t
197
198 - Set files with the lsmd_plugin_tmp_t type, if you want to store lsmd
199 plugin temporary files in the /tmp directories.
200
201
202
203 Note: File context can be temporarily modified with the chcon command.
204 If you want to permanently change the file context you need to use the
205 semanage fcontext command. This will modify the SELinux labeling data‐
206 base. You will need to use restorecon to apply the labels.
207
208
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212
213 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215
216 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218
219 semanage boolean can also be used to manipulate the booleans
220
221
222 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
