NAME

6       smsd_selinux - Security Enhanced Linux Policy for the smsd processes
7

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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. Disabled by default.
87
88       setsebool -P nscd_use_shm 1
89

MANAGED FILES

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.

FILE CONTEXTS

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

COMMANDS

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.
