NAME

6       netlogond_selinux  -  Security  Enhanced Linux Policy for the netlogond
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the netlogond  processes  via  flexible
11       mandatory access control.
12
13       The  netlogond processes execute with the netlogond_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep netlogond_t
20
21
22

ENTRYPOINTS

24       The  netlogond_t  SELinux  type can be entered via the netlogond_exec_t
25       file type.
26
27       The default entrypoint paths for the netlogond_t domain are the follow‐
28       ing:
29
30       /usr/sbin/netlogond, /opt/likewise/sbin/netlogond
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       netlogond  policy is very flexible allowing users to setup their netlo‐
40       gond processes in as secure a method as possible.
41
42       The following process types are defined for netlogond:
43
44       netlogond_t
45
46       Note: semanage permissive -a  netlogond_t  can  be  used  to  make  the
47       process  type  netlogond_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy is customizable based on least access required.  netlo‐
54       gond policy is extremely flexible and has several booleans  that  allow
55       you to manipulate the policy and run netlogond with the tightest access
56       possible.

MANAGED FILES

149       The SELinux process type netlogond_t can manage files labeled with  the
150       following file types.  The paths listed are the default paths for these
151       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

205       SELinux requires files to have an extended attribute to define the file
206       type.
207
208       You can see the context of a file using the -Z option to ls
209
210       Policy  governs  the  access  confined  processes  have to these files.
211       SELinux netlogond policy is very flexible allowing users to setup their
212       netlogond processes in as secure a method as possible.
213
214       STANDARD FILE CONTEXT
215
216       SELinux defines the file context types for the netlogond, if you wanted
217       to store files with these types in a diffent paths, you need to execute
218       the  semanage  command  to  sepecify  alternate  labeling  and then use
219       restorecon to put the labels on disk.
220
221       semanage fcontext -a -t  netlogond_var_socket_t  '/srv/mynetlogond_con‐
222       tent(/.*)?'
223       restorecon -R -v /srv/mynetlogond_content
224
225       Note:  SELinux  often  uses  regular expressions to specify labels that
226       match multiple files.
227
228       The following file types are defined for netlogond:
229
230
231
232       netlogond_exec_t
233
234       - Set files with the netlogond_exec_t type, if you want  to  transition
235       an executable to the netlogond_t domain.
236
237
238       Paths:
239            /usr/sbin/netlogond, /opt/likewise/sbin/netlogond
240
241
242       netlogond_var_lib_t
243
244       - Set files with the netlogond_var_lib_t type, if you want to store the
245       netlogond files under the /var/lib directory.
246
247
248       Paths:
249            /var/lib/likewise/LWNetsd.err, /var/lib/likewise-open/LWNetsd.err,
250            /var/lib/likewise/krb5-affinity.conf,           /var/lib/likewise-
251            open/krb5-affinity.conf
252
253
254       netlogond_var_run_t
255
256       - Set files with the netlogond_var_run_t type, if you want to store the
257       netlogond files under the /run or /var/run directory.
258
259
260
261       netlogond_var_socket_t
262
263       -  Set files with the netlogond_var_socket_t type, if you want to treat
264       the files as netlogond var socket data.
265
266
267       Paths:
268            /var/lib/likewise/.netlogond, /var/lib/likewise-open/.netlogond
269
270
271       Note: File context can be temporarily modified with the chcon  command.
272       If  you want to permanently change the file context you need to use the
273       semanage fcontext command.  This will modify the SELinux labeling data‐
274       base.  You will need to use restorecon to apply the labels.
275
276

COMMANDS

278       semanage  fcontext  can also be used to manipulate default file context
279       mappings.
280
281       semanage permissive can also be used to manipulate  whether  or  not  a
282       process type is permissive.
283
284       semanage  module can also be used to enable/disable/install/remove pol‐
285       icy modules.
286
287       semanage boolean can also be used to manipulate the booleans
288
289
290       system-config-selinux is a GUI tool available to customize SELinux pol‐
291       icy settings.
