NAME

6       uuidd_selinux - Security Enhanced Linux Policy for the uuidd processes
7

DESCRIPTION

9       Security-Enhanced Linux secures the uuidd processes via flexible manda‐
10       tory access control.
11
12       The uuidd processes execute with the  uuidd_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 uuidd_t
19
20
21

ENTRYPOINTS

23       The uuidd_t SELinux type can be entered via the uuidd_exec_t file type.
24
25       The default entrypoint paths for the uuidd_t domain are the following:
26
27       /usr/sbin/uuidd
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       uuidd policy is very flexible allowing users to setup their uuidd  pro‐
37       cesses in as secure a method as possible.
38
39       The following process types are defined for uuidd:
40
41       uuidd_t
42
43       Note:  semanage  permissive  -a uuidd_t can be used to make the process
44       type uuidd_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.   uuidd
51       policy is extremely flexible and has several booleans that allow you to
52       manipulate the policy and run uuidd with the tightest access possible.

MANAGED FILES

138       The SELinux process type uuidd_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  uuidd  policy  is  very flexible allowing users to setup their
194       uuidd processes in as secure a method as possible.
195
196       STANDARD FILE CONTEXT
197
198       SELinux defines the file context types for the uuidd, 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 uuidd_var_run_t '/srv/myuuidd_content(/.*)?'
204       restorecon -R -v /srv/myuuidd_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 uuidd:
210
211
212
213       uuidd_exec_t
214
215       - Set files with the uuidd_exec_t type, if you want  to  transition  an
216       executable to the uuidd_t domain.
217
218
219
220       uuidd_initrc_exec_t
221
222       -  Set  files with the uuidd_initrc_exec_t type, if you want to transi‐
223       tion an executable to the uuidd_initrc_t domain.
224
225
226
227       uuidd_var_lib_t
228
229       - Set files with the uuidd_var_lib_t type, if you  want  to  store  the
230       uuidd files under the /var/lib directory.
231
232
233
234       uuidd_var_run_t
235
236       -  Set  files  with  the uuidd_var_run_t type, if you want to store the
237       uuidd files under the /run or /var/run directory.
238
239
240
241       Note: File context can be temporarily modified with the chcon  command.
242       If  you want to permanently change the file context you need to use the
243       semanage fcontext command.  This will modify the SELinux labeling data‐
244       base.  You will need to use restorecon to apply the labels.
245
246

COMMANDS

248       semanage  fcontext  can also be used to manipulate default file context
249       mappings.
250
251       semanage permissive can also be used to manipulate  whether  or  not  a
252       process type is permissive.
253
254       semanage  module can also be used to enable/disable/install/remove pol‐
255       icy modules.
256
257       semanage boolean can also be used to manipulate the booleans
258
259
260       system-config-selinux is a GUI tool available to customize SELinux pol‐
261       icy settings.
