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 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 For example:
18 ps -eZ | grep lsmd_plugin_t
20
24 The lsmd_plugin_t SELinux type can be entered via the lsmd_plug‐
25 in_exec_t file type.
26 The default entrypoint paths for the lsmd_plugin_t domain are the fol‐
28 lowing:
29 /usr/bin/.*_lsmplugin
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 lsmd_plugin policy is very flexible allowing users to setup their
40 lsmd_plugin processes in as secure a method as possible.
41 The following process types are defined for lsmd_plugin:
43 lsmd_plugin_t
45 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
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 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 setsebool -P lsmd_plugin_connect_any 1
65 If you want to allow users to resolve user passwd entries directly from
69 ldap rather then using a sssd server, you must turn on the authlo‐
70 gin_nsswitch_use_ldap boolean. Disabled by default.
71 setsebool -P authlogin_nsswitch_use_ldap 1
73 If you want to deny any process from ptracing or debugging any other
77 processes, you must turn on the deny_ptrace boolean. Enabled by
78 default.
79 setsebool -P deny_ptrace 1
81 If you want to allow any process to mmap any file on system with
85 attribute file_type, you must turn on the domain_can_mmap_files bool‐
86 ean. Enabled by default.
87 setsebool -P domain_can_mmap_files 1
89 If you want to allow all domains write to kmsg_device, while kernel is
93 executed with systemd.log_target=kmsg parameter, you must turn on the
94 domain_can_write_kmsg boolean. Disabled by default.
95 setsebool -P domain_can_write_kmsg 1
97 If you want to allow all domains to use other domains file descriptors,
101 you must turn on the domain_fd_use boolean. Enabled by default.
102 setsebool -P domain_fd_use 1
104 If you want to allow all domains to have the kernel load modules, you
108 must turn on the domain_kernel_load_modules boolean. Disabled by
109 default.
110 setsebool -P domain_kernel_load_modules 1
112 If you want to allow all domains to execute in fips_mode, you must turn
116 on the fips_mode boolean. Enabled by default.
117 setsebool -P fips_mode 1
119 If you want to enable reading of urandom for all domains, you must turn
123 on the global_ssp boolean. Disabled by default.
124 setsebool -P global_ssp 1
126 If you want to allow confined applications to run with kerberos, you
130 must turn on the kerberos_enabled boolean. Enabled by default.
131 setsebool -P kerberos_enabled 1
133 If you want to allow system to run with NIS, you must turn on the
137 nis_enabled boolean. Disabled by default.
138 setsebool -P nis_enabled 1
140 If you want to allow confined applications to use nscd shared memory,
144 you must turn on the nscd_use_shm boolean. Disabled by default.
145 setsebool -P nscd_use_shm 1
147
151 The SELinux process type lsmd_plugin_t can manage files labeled with
152 the following file types. The paths listed are the default paths for
153 these file types. Note the processes UID still need to have DAC per‐
154 missions.
155 lsmd_plugin_tmp_t
157
161 SELinux requires files to have an extended attribute to define the file
162 type.
163 You can see the context of a file using the -Z option to ls
165 Policy governs the access confined processes have to these files.
167 SELinux lsmd_plugin policy is very flexible allowing users to setup
168 their lsmd_plugin processes in as secure a method as possible.
169 STANDARD FILE CONTEXT
171 SELinux defines the file context types for the lsmd_plugin, if you
173 wanted to store files with these types in a diffent paths, you need to
174 execute the semanage command to sepecify alternate labeling and then
175 use restorecon to put the labels on disk.
176 semanage fcontext -a -t lsmd_plugin_tmp_t '/srv/mylsmd_plugin_con‐
178 tent(/.*)?'
179 restorecon -R -v /srv/mylsmd_plugin_content
180 Note: SELinux often uses regular expressions to specify labels that
182 match multiple files.
183 The following file types are defined for lsmd_plugin:
185 lsmd_plugin_exec_t
189 - Set files with the lsmd_plugin_exec_t type, if you want to transition
191 an executable to the lsmd_plugin_t domain.
192 lsmd_plugin_tmp_t
196 - Set files with the lsmd_plugin_tmp_t type, if you want to store lsmd
198 plugin temporary files in the /tmp directories.
199 Note: File context can be temporarily modified with the chcon command.
203 If you want to permanently change the file context you need to use the
204 semanage fcontext command. This will modify the SELinux labeling data‐
205 base. You will need to use restorecon to apply the labels.
206
209 semanage fcontext can also be used to manipulate default file context
210 mappings.
211 semanage permissive can also be used to manipulate whether or not a
213 process type is permissive.
214 semanage module can also be used to enable/disable/install/remove pol‐
216 icy modules.
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.
