NAME

6       lpd_selinux - Security Enhanced Linux Policy for the lpd processes
7

DESCRIPTION

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

ENTRYPOINTS

23       The lpd_t SELinux type can be entered via the lpd_exec_t file type.
24
25       The default entrypoint paths for the lpd_t domain are the following:
26
27       /usr/sbin/lpd
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       lpd policy is very flexible allowing users to setup their lpd processes
37       in as secure a method as possible.
38
39       The following process types are defined for lpd:
40
41       lpd_t
42
43       Note: semanage permissive -a lpd_t can be used to make the process type
44       lpd_t permissive. SELinux does not deny access  to  permissive  process
45       types, but the AVC (SELinux denials) messages are still generated.
46
47

BOOLEANS

49       SELinux  policy  is  customizable  based on least access required.  lpd
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run lpd with the tightest access possible.

93       ean. Enabled by default.

MANAGED FILES

144       The  SELinux  process type lpd_t can manage files labeled with the fol‐
145       lowing file types.  The paths listed are the default  paths  for  these
146       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

199       SELinux requires files to have an extended attribute to define the file
200       type.
201
202       You can see the context of a file using the -Z option to ls
203
204       Policy governs the access  confined  processes  have  to  these  files.
205       SELinux  lpd  policy is very flexible allowing users to setup their lpd
206       processes in as secure a method as possible.
207
208       STANDARD FILE CONTEXT
209
210       SELinux defines the file context types for the lpd, if  you  wanted  to
211       store  files  with  these types in a diffent paths, you need to execute
212       the semanage command  to  sepecify  alternate  labeling  and  then  use
213       restorecon to put the labels on disk.
214
215       semanage fcontext -a -t lpd_var_run_t '/srv/mylpd_content(/.*)?'
216       restorecon -R -v /srv/mylpd_content
217
218       Note:  SELinux  often  uses  regular expressions to specify labels that
219       match multiple files.
220
221       The following file types are defined for lpd:
222
223
224
225       lpd_exec_t
226
227       - Set files with the lpd_exec_t type, if you want to transition an exe‐
228       cutable to the lpd_t domain.
229
230
231
232       lpd_tmp_t
233
234       - Set files with the lpd_tmp_t type, if you want to store lpd temporary
235       files in the /tmp directories.
236
237
238
239       lpd_var_run_t
240
241       - Set files with the lpd_var_run_t type, if you want to store  the  lpd
242       files under the /run or /var/run directory.
243
244
245       Paths:
246            /var/run/lprng(/.*)?, /var/spool/turboprint(/.*)?
247
248
249       Note:  File context can be temporarily modified with the chcon command.
250       If you want to permanently change the file context you need to use  the
251       semanage fcontext command.  This will modify the SELinux labeling data‐
252       base.  You will need to use restorecon to apply the labels.
253
254

COMMANDS

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