NAME

6       fprintd_selinux  -  Security Enhanced Linux Policy for the fprintd pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The  fprintd_t  SELinux type can be entered via the fprintd_exec_t file
25       type.
26
27       The default entrypoint paths for the fprintd_t domain are  the  follow‐
28       ing:
29
30       /usr/libexec/fprintd
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       fprintd  policy  is very flexible allowing users to setup their fprintd
40       processes in as secure a method as possible.
41
42       The following process types are defined for fprintd:
43
44       fprintd_t
45
46       Note: semanage permissive -a fprintd_t can be used to make the  process
47       type  fprintd_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

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

MANAGED FILES

171       The SELinux process type fprintd_t can manage files  labeled  with  the
172       following file types.  The paths listed are the default paths for these
173       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

216       SELinux requires files to have an extended attribute to define the file
217       type.
218
219       You can see the context of a file using the -Z option to ls
220
221       Policy  governs  the  access  confined  processes  have to these files.
222       SELinux fprintd policy is very flexible allowing users to  setup  their
223       fprintd processes in as secure a method as possible.
224
225       STANDARD FILE CONTEXT
226
227       SELinux  defines  the file context types for the fprintd, if you wanted
228       to store files with these types in a diffent paths, you need to execute
229       the  semanage  command  to  sepecify  alternate  labeling  and then use
230       restorecon to put the labels on disk.
231
232       semanage  fcontext   -a   -t   fprintd_var_lib_t   '/srv/myfprintd_con‐
233       tent(/.*)?'
234       restorecon -R -v /srv/myfprintd_content
235
236       Note:  SELinux  often  uses  regular expressions to specify labels that
237       match multiple files.
238
239       The following file types are defined for fprintd:
240
241
242
243       fprintd_exec_t
244
245       - Set files with the fprintd_exec_t type, if you want to transition  an
246       executable to the fprintd_t domain.
247
248
249
250       fprintd_var_lib_t
251
252       -  Set  files with the fprintd_var_lib_t type, if you want to store the
253       fprintd files under the /var/lib directory.
254
255
256
257       Note: File context can be temporarily modified with the chcon  command.
258       If  you want to permanently change the file context you need to use the
259       semanage fcontext command.  This will modify the SELinux labeling data‐
260       base.  You will need to use restorecon to apply the labels.
261
262

COMMANDS

264       semanage  fcontext  can also be used to manipulate default file context
265       mappings.
266
267       semanage permissive can also be used to manipulate  whether  or  not  a
268       process type is permissive.
269
270       semanage  module can also be used to enable/disable/install/remove pol‐
271       icy modules.
272
273       semanage boolean can also be used to manipulate the booleans
274
275
276       system-config-selinux is a GUI tool available to customize SELinux pol‐
277       icy settings.
