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.

128 SELinux requires files to have an extended attribute to define the file
129 type.
130 You can see the context of a file using the -Z option to ls
132 Policy governs the access confined processes have to these files.
134 SELinux smsd policy is very flexible allowing users to setup their smsd
135 processes in as secure a method as possible.
136 STANDARD FILE CONTEXT
138 SELinux defines the file context types for the smsd, if you wanted to
140 store files with these types in a diffent paths, you need to execute
141 the semanage command to sepecify alternate labeling and then use
142 restorecon to put the labels on disk.
143 semanage fcontext -a -t smsd_tmp_t '/srv/mysmsd_content(/.*)?'
145 restorecon -R -v /srv/mysmsd_content
146 Note: SELinux often uses regular expressions to specify labels that
148 match multiple files.
149 The following file types are defined for smsd:
151 smsd_exec_t
155 - Set files with the smsd_exec_t type, if you want to transition an
157 executable to the smsd_t domain.
158 smsd_initrc_exec_t
162 - Set files with the smsd_initrc_exec_t type, if you want to transition
164 an executable to the smsd_initrc_t domain.
165 smsd_log_t
169 - Set files with the smsd_log_t type, if you want to treat the data as
171 smsd log data, usually stored under the /var/log directory.
172 smsd_spool_t
176 - Set files with the smsd_spool_t type, if you want to store the smsd
178 files under the /var/spool directory.
179 smsd_tmp_t
183 - Set files with the smsd_tmp_t type, if you want to store smsd tempo‐
185 rary files in the /tmp directories.
186 smsd_var_lib_t
190 - Set files with the smsd_var_lib_t type, if you want to store the smsd
192 files under the /var/lib directory.
193 smsd_var_run_t
197 - Set files with the smsd_var_run_t type, if you want to store the smsd
199 files under the /run or /var/run directory.
200 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
210 semanage fcontext can also be used to manipulate default file context
211 mappings.
212 semanage permissive can also be used to manipulate whether or not a
214 process type is permissive.
215 semanage module can also be used to enable/disable/install/remove pol‐
217 icy modules.
218 semanage boolean can also be used to manipulate the booleans
220 system-config-selinux is a GUI tool available to customize SELinux pol‐
223 icy settings.
