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.

MANAGED FILES

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

FILE CONTEXTS

211       SELinux requires files to have an extended attribute to define the file
212       type.
213
214       You can see the context of a file using the -Z option to ls
215
216       Policy  governs  the  access  confined  processes  have to these files.
217       SELinux lpd policy is very flexible allowing users to setup  their  lpd
218       processes in as secure a method as possible.
219
220       STANDARD FILE CONTEXT
221
222       SELinux  defines  the  file context types for the lpd, if you wanted to
223       store files with these types in a diffent paths, you  need  to  execute
224       the  semanage  command  to  sepecify  alternate  labeling  and then use
225       restorecon to put the labels on disk.
226
227       semanage fcontext -a -t lpd_var_run_t '/srv/mylpd_content(/.*)?'
228       restorecon -R -v /srv/mylpd_content
229
230       Note: SELinux often uses regular expressions  to  specify  labels  that
231       match multiple files.
232
233       The following file types are defined for lpd:
234
235
236
237       lpd_exec_t
238
239       - Set files with the lpd_exec_t type, if you want to transition an exe‐
240       cutable to the lpd_t domain.
241
242
243
244       lpd_tmp_t
245
246       - Set files with the lpd_tmp_t type, if you want to store lpd temporary
247       files in the /tmp directories.
248
249
250
251       lpd_var_run_t
252
253       -  Set  files with the lpd_var_run_t type, if you want to store the lpd
254       files under the /run or /var/run directory.
255
256
257
258       Note: File context can be temporarily modified with the chcon  command.
259       If  you want to permanently change the file context you need to use the
260       semanage fcontext command.  This will modify the SELinux labeling data‐
261       base.  You will need to use restorecon to apply the labels.
262
263

COMMANDS

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