NAME

6       cupsd_selinux - Security Enhanced Linux Policy for the cupsd processes
7

DESCRIPTION

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

ENTRYPOINTS

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

151       lowing file types.  The paths listed are the default  paths  for  these
152       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

298       SELinux requires files to have an extended attribute to define the file
299       type.
300
301       You can see the context of a file using the -Z option to ls
302
303       Policy governs the access  confined  processes  have  to  these  files.
304       SELinux  cupsd  policy  is  very flexible allowing users to setup their
305       cupsd processes in as secure a method as possible.
306
307       STANDARD FILE CONTEXT
308
309       SELinux defines the file context types for the cupsd, if you wanted  to
310       store  files  with  these types in a diffent paths, you need to execute
311       the semanage command  to  sepecify  alternate  labeling  and  then  use
312       restorecon to put the labels on disk.
313
314       semanage fcontext -a -t cupsd_var_run_t '/srv/mycupsd_content(/.*)?'
315       restorecon -R -v /srv/mycupsd_content
316
317       Note:  SELinux  often  uses  regular expressions to specify labels that
318       match multiple files.
319
320       The following file types are defined for cupsd:
321

451
452
453       Note:  File context can be temporarily modified with the chcon command.
454       If you want to permanently change the file context you need to use  the
455       semanage fcontext command.  This will modify the SELinux labeling data‐
456       base.  You will need to use restorecon to apply the labels.
457
458

COMMANDS

460       semanage fcontext can also be used to manipulate default  file  context
461       mappings.
462
463       semanage  permissive  can  also  be used to manipulate whether or not a
464       process type is permissive.
465
466       semanage module can also be used to enable/disable/install/remove  pol‐
