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 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 For example:
17 ps -eZ | grep smsd_t
19
23 The smsd_t SELinux type can be entered via the smsd_exec_t file type.
24 The default entrypoint paths for the smsd_t domain are the following:
26 /usr/sbin/smsd
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 smsd policy is very flexible allowing users to setup their smsd pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for smsd:
40 smsd_t
42 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
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 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 The SELinux process type smsd_t can manage files labeled with the fol‐
72 lowing file types. The paths listed are the default paths for these
73 file types. Note the processes UID still need to have DAC permissions.

146 SELinux requires files to have an extended attribute to define the file
147 type.
148 You can see the context of a file using the -Z option to ls
150 Policy governs the access confined processes have to these files.
152 SELinux smsd policy is very flexible allowing users to setup their smsd
153 processes in as secure a method as possible.
154 STANDARD FILE CONTEXT
156 SELinux defines the file context types for the smsd, if you wanted to
158 store files with these types in a diffent paths, you need to execute
159 the semanage command to specify alternate labeling and then use re‐
160 storecon to put the labels on disk.
161 semanage fcontext -a -t smsd_tmp_t '/srv/mysmsd_content(/.*)?'
163 restorecon -R -v /srv/mysmsd_content
164 Note: SELinux often uses regular expressions to specify labels that
166 match multiple files.
167 The following file types are defined for smsd:
169 smsd_exec_t
173 - Set files with the smsd_exec_t type, if you want to transition an ex‐
175 ecutable to the smsd_t domain.
176 smsd_initrc_exec_t
180 - Set files with the smsd_initrc_exec_t type, if you want to transition
182 an executable to the smsd_initrc_t domain.
183 smsd_log_t
187 - Set files with the smsd_log_t type, if you want to treat the data as
189 smsd log data, usually stored under the /var/log directory.
190 smsd_spool_t
194 - Set files with the smsd_spool_t type, if you want to store the smsd
196 files under the /var/spool directory.
197 smsd_tmp_t
201 - Set files with the smsd_tmp_t type, if you want to store smsd tempo‐
203 rary files in the /tmp directories.
204 smsd_var_lib_t
208 - Set files with the smsd_var_lib_t type, if you want to store the smsd
210 files under the /var/lib directory.
211 smsd_var_run_t
215 - Set files with the smsd_var_run_t type, if you want to store the smsd
217 files under the /run or /var/run directory.
218 Note: File context can be temporarily modified with the chcon command.
222 If you want to permanently change the file context you need to use the
223 semanage fcontext command. This will modify the SELinux labeling data‐
224 base. You will need to use restorecon to apply the labels.
225
228 semanage fcontext can also be used to manipulate default file context
229 mappings.
230 semanage permissive can also be used to manipulate whether or not a
232 process type is permissive.
233 semanage module can also be used to enable/disable/install/remove pol‐
235 icy modules.
236 semanage boolean can also be used to manipulate the booleans
238 system-config-selinux is a GUI tool available to customize SELinux pol‐
241 icy settings.
