NAME

6       lwsmd_selinux - Security Enhanced Linux Policy for the lwsmd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The lwsmd_t SELinux type can be entered via the lwsmd_exec_t file type.
24
25       The default entrypoint paths for the lwsmd_t domain are the following:
26
27       /usr/sbin/lwsmd, /opt/likewise/sbin/lwsmd
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       lwsmd policy is very flexible allowing users to setup their lwsmd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for lwsmd:
40
41       lwsmd_t
42
43       Note:  semanage  permissive  -a lwsmd_t can be used to make the process
44       type lwsmd_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.   lwsmd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run lwsmd with the tightest access possible.
53
54
55
56       If you want to allow all daemons to write corefiles to /, you must turn

MANAGED FILES

138       The SELinux process type lwsmd_t can manage files labeled with the fol‐
139       lowing file types.  The paths listed are the default  paths  for  these
140       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

187       SELinux requires files to have an extended attribute to define the file
188       type.
189
190       You can see the context of a file using the -Z option to ls
191
192       Policy governs the access  confined  processes  have  to  these  files.
193       SELinux  lwsmd  policy  is  very flexible allowing users to setup their
194       lwsmd processes in as secure a method as possible.
195
196       STANDARD FILE CONTEXT
197
198       SELinux defines the file context types for the lwsmd, if you wanted  to
199       store  files  with  these types in a diffent paths, you need to execute
200       the semanage command  to  sepecify  alternate  labeling  and  then  use
201       restorecon to put the labels on disk.
202
203       semanage fcontext -a -t lwsmd_var_socket_t '/srv/mylwsmd_content(/.*)?'
204       restorecon -R -v /srv/mylwsmd_content
205
206       Note:  SELinux  often  uses  regular expressions to specify labels that
207       match multiple files.
208
209       The following file types are defined for lwsmd:
210
211
212
213       lwsmd_exec_t
214
215       - Set files with the lwsmd_exec_t type, if you want  to  transition  an
216       executable to the lwsmd_t domain.
217
218
219       Paths:
220            /usr/sbin/lwsmd, /opt/likewise/sbin/lwsmd
221
222
223       lwsmd_var_lib_t
224
225       -  Set  files  with  the lwsmd_var_lib_t type, if you want to store the
226       lwsmd files under the /var/lib directory.
227
228
229       Paths:
230            /var/lib/likewise/.lwsmd-lock, /var/lib/likewise-open/.lwsmd-lock
231
232
233       lwsmd_var_run_t
234
235       - Set files with the lwsmd_var_run_t type, if you  want  to  store  the
236       lwsmd files under the /run or /var/run directory.
237
238
239
240       lwsmd_var_socket_t
241
242       -  Set files with the lwsmd_var_socket_t type, if you want to treat the
243       files as lwsmd var socket data.
244
245
246       Paths:
247            /var/lib/likewise/.lwsm, /var/lib/likewise-open/.lwsm
248
249
250       Note: File context can be temporarily modified with the chcon  command.
251       If  you want to permanently change the file context you need to use the
252       semanage fcontext command.  This will modify the SELinux labeling data‐
253       base.  You will need to use restorecon to apply the labels.
254
255

COMMANDS

257       semanage  fcontext  can also be used to manipulate default file context
258       mappings.
259
260       semanage permissive can also be used to manipulate  whether  or  not  a
261       process type is permissive.
262
263       semanage  module can also be used to enable/disable/install/remove pol‐
264       icy modules.
265
266       semanage boolean can also be used to manipulate the booleans
267
268
269       system-config-selinux is a GUI tool available to customize SELinux pol‐
270       icy settings.
