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/hp-[^/]+, /usr/share/hplip/.*.py, /usr/lib/cups/backend/hp.*,
28       /usr/bin/hpijs,   /usr/sbin/cupsd,   /usr/sbin/hpiod,   /usr/sbin/cups-
29       browsed

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       cupsd policy is very flexible allowing users to setup their cupsd  pro‐
39       cesses in as secure a method as possible.
40
41       The following process types are defined for cupsd:
42
43       cupsd_config_t, cupsd_t, cupsd_lpd_t, cups_pdf_t
44
45       Note:  semanage  permissive  -a cupsd_t can be used to make the process
46       type cupsd_t permissive. SELinux does not  deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

52       SELinux policy is customizable based on least access  required.   cupsd
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run cupsd with the tightest access possible.
55
56
57
58       If you want to allow cups  execmem/execstack,  you  must  turn  on  the
59       cups_execmem boolean. Disabled by default.
60
61       setsebool -P cups_execmem 1
62
63
64
65       If you want to allow users to resolve user passwd entries directly from
66       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
67       gin_nsswitch_use_ldap boolean. Disabled by default.
68
69       setsebool -P authlogin_nsswitch_use_ldap 1
70
71
72
73       If you want to allow all domains to execute in fips_mode, you must turn
74       on the fips_mode boolean. Enabled by default.
75
76       setsebool -P fips_mode 1
77
78
79
80       If you want to allow confined applications to run  with  kerberos,  you
81       must turn on the kerberos_enabled boolean. Enabled by default.
82
83       setsebool -P kerberos_enabled 1
84
85
86
87       If  you  want  to  allow  system  to run with NIS, you must turn on the
88       nis_enabled boolean. Disabled by default.
89
90       setsebool -P nis_enabled 1
91
92
93
94       If you want to allow confined applications to use nscd  shared  memory,
95       you must turn on the nscd_use_shm boolean. Disabled by default.
96
97       setsebool -P nscd_use_shm 1
98
99

MANAGED FILES

102       The SELinux process type cupsd_t can manage files labeled with the fol‐
103       lowing file types.  The paths listed are the default  paths  for  these
104       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

259       SELinux requires files to have an extended attribute to define the file
260       type.
261
262       You can see the context of a file using the -Z option to ls
263
264       Policy governs the access  confined  processes  have  to  these  files.
265       SELinux  cupsd  policy  is  very flexible allowing users to setup their
266       cupsd processes in as secure a method as possible.
267
268       STANDARD FILE CONTEXT
269
270       SELinux defines the file context types for the cupsd, if you wanted  to
271       store  files  with  these types in a diffent paths, you need to execute
272       the semanage command  to  sepecify  alternate  labeling  and  then  use
273       restorecon to put the labels on disk.
274
275       semanage fcontext -a -t cupsd_unit_file_t '/srv/mycupsd_content(/.*)?'
276       restorecon -R -v /srv/mycupsd_content
277
278       Note:  SELinux  often  uses  regular expressions to specify labels that
279       match multiple files.
280
281       The following file types are defined for cupsd:
282
283

288       tion an executable to the cupsd_config_t domain.
