6 smsd_selinux - Security Enhanced Linux Policy for the smsd processes
7
9 Security-Enhanced Linux secures the smsd processes via flexible manda‐
10 tory access control.
11
12 The smsd processes execute with the smsd_t SELinux type. You can check
13 if you have these processes running by executing the ps command with
14 the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep smsd_t
19
20
21
23 The smsd_t SELinux type can be entered via the smsd_exec_t file type.
24
25 The default entrypoint paths for the smsd_t domain are the following:
26
27 /usr/sbin/smsd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 smsd policy is very flexible allowing users to setup their smsd pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for smsd:
40
41 smsd_t
42
43 Note: semanage permissive -a smsd_t can be used to make the process
44 type smsd_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. smsd
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run smsd with the tightest access possible.
53
54
55
56 If you want to allow users to resolve user passwd entries directly from
57 ldap rather then using a sssd server, you must turn on the authlo‐
58 gin_nsswitch_use_ldap boolean. Disabled by default.
59
60 setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
71 If you want to allow confined applications to run with kerberos, you
72 must turn on the kerberos_enabled boolean. Enabled by default.
73
74 setsebool -P kerberos_enabled 1
75
76
77
78 If you want to allow system to run with NIS, you must turn on the
79 nis_enabled boolean. Disabled by default.
80
81 setsebool -P nis_enabled 1
82
83
84
85 If you want to allow confined applications to use nscd shared memory,
86 you must turn on the nscd_use_shm boolean. Enabled by default.
87
88 setsebool -P nscd_use_shm 1
89
90
91
93 The SELinux process type smsd_t can manage files labeled with the fol‐
94 lowing file types. The paths listed are the default paths for these
95 file types. Note the processes UID still need to have DAC permissions.

153 SELinux requires files to have an extended attribute to define the file
154 type.
155
156 You can see the context of a file using the -Z option to ls
157
158 Policy governs the access confined processes have to these files.
159 SELinux smsd policy is very flexible allowing users to setup their smsd
160 processes in as secure a method as possible.
161
162 STANDARD FILE CONTEXT
163
164 SELinux defines the file context types for the smsd, if you wanted to
165 store files with these types in a diffent paths, you need to execute
166 the semanage command to sepecify alternate labeling and then use
167 restorecon to put the labels on disk.
168
169 semanage fcontext -a -t smsd_tmp_t '/srv/mysmsd_content(/.*)?'
170 restorecon -R -v /srv/mysmsd_content
171
172 Note: SELinux often uses regular expressions to specify labels that
173 match multiple files.
174
175 The following file types are defined for smsd:
176
177
178
179 smsd_exec_t
180
181 - Set files with the smsd_exec_t type, if you want to transition an
182 executable to the smsd_t domain.
183
184
185
186 smsd_initrc_exec_t
187
188 - Set files with the smsd_initrc_exec_t type, if you want to transition
189 an executable to the smsd_initrc_t domain.
190
191
192
193 smsd_log_t
194
195 - Set files with the smsd_log_t type, if you want to treat the data as
196 smsd log data, usually stored under the /var/log directory.
197
198
199
200 smsd_spool_t
201
202 - Set files with the smsd_spool_t type, if you want to store the smsd
203 files under the /var/spool directory.
204
205
206
207 smsd_tmp_t
208
209 - Set files with the smsd_tmp_t type, if you want to store smsd tempo‐
210 rary files in the /tmp directories.
211
212
213
214 smsd_var_lib_t
215
216 - Set files with the smsd_var_lib_t type, if you want to store the smsd
217 files under the /var/lib directory.
218
219
220
221 smsd_var_run_t
222
223 - Set files with the smsd_var_run_t type, if you want to store the smsd
224 files under the /run or /var/run directory.
225
226
227
228 Note: File context can be temporarily modified with the chcon command.
229 If you want to permanently change the file context you need to use the
230 semanage fcontext command. This will modify the SELinux labeling data‐
231 base. You will need to use restorecon to apply the labels.
232
233
235 semanage fcontext can also be used to manipulate default file context
236 mappings.
237
238 semanage permissive can also be used to manipulate whether or not a
239 process type is permissive.
240
241 semanage module can also be used to enable/disable/install/remove pol‐
242 icy modules.
243
244 semanage boolean can also be used to manipulate the booleans
245
246
247 system-config-selinux is a GUI tool available to customize SELinux pol‐
248 icy settings.
