6 cupsd_config_selinux - Security Enhanced Linux Policy for the
7 cupsd_config processes
8
10 Security-Enhanced Linux secures the cupsd_config processes via flexible
11 mandatory access control.
12 The cupsd_config processes execute with the cupsd_config_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep cupsd_config_t
20
24 The cupsd_config_t SELinux type can be entered via the cupsd_con‐
25 fig_exec_t file type.
26 The default entrypoint paths for the cupsd_config_t domain are the fol‐
28 lowing:
29 /usr/sbin/hal_lpadmin, /usr/libexec/hal_lpadmin, /usr/bin/cups-config-
31 daemon, /usr/sbin/printconf-backend, /usr/lib/udev/udev-configure-
32 printer, /usr/libexec/cups-pk-helper-mechanism
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 cupsd_config policy is very flexible allowing users to setup their
42 cupsd_config processes in as secure a method as possible.
43 The following process types are defined for cupsd_config:
45 cupsd_config_t
47 Note: semanage permissive -a cupsd_config_t can be used to make the
49 process type cupsd_config_t permissive. SELinux does not deny access to
50 permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required.
56 cupsd_config policy is extremely flexible and has several booleans that
57 allow you to manipulate the policy and run cupsd_config with the tight‐
58 est access possible.
59 If you want to allow users to resolve user passwd entries directly from
63 ldap rather then using a sssd server, you must turn on the authlo‐
64 gin_nsswitch_use_ldap boolean. Disabled by default.
65 setsebool -P authlogin_nsswitch_use_ldap 1
67 If you want to allow cups execmem/execstack, you must turn on the
71 cups_execmem boolean. Disabled by default.
72 setsebool -P cups_execmem 1
74 If you want to allow all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79 setsebool -P fips_mode 1
81 If you want to allow confined applications to run with kerberos, you
85 must turn on the kerberos_enabled boolean. Enabled by default.
86 setsebool -P kerberos_enabled 1
88 If you want to allow system to run with NIS, you must turn on the
92 nis_enabled boolean. Disabled by default.
93 setsebool -P nis_enabled 1
95 If you want to allow confined applications to use nscd shared memory,
99 you must turn on the nscd_use_shm boolean. Enabled by default.
100 setsebool -P nscd_use_shm 1

106 The SELinux process type cupsd_config_t can manage files labeled with
107 the following file types. The paths listed are the default paths for
108 these file types. Note the processes UID still need to have DAC per‐
109 missions.

212 SELinux requires files to have an extended attribute to define the file
213 type.
214 You can see the context of a file using the -Z option to ls
216 Policy governs the access confined processes have to these files.
218 SELinux cupsd_config policy is very flexible allowing users to setup
219 their cupsd_config processes in as secure a method as possible.
220 STANDARD FILE CONTEXT
222 SELinux defines the file context types for the cupsd_config, if you
224 wanted to store files with these types in a diffent paths, you need to
225 execute the semanage command to sepecify alternate labeling and then
226 use restorecon to put the labels on disk.
227 semanage fcontext -a -t cupsd_config_var_run_t '/srv/mycupsd_con‐
229 fig_content(/.*)?'
230 restorecon -R -v /srv/mycupsd_config_content
231 Note: SELinux often uses regular expressions to specify labels that
233 match multiple files.
234 The following file types are defined for cupsd_config:
236 cupsd_config_exec_t
240 - Set files with the cupsd_config_exec_t type, if you want to transi‐
242 tion an executable to the cupsd_config_t domain.
243 Paths:
246 /usr/sbin/hal_lpadmin, /usr/libexec/hal_lpadmin, /usr/bin/cups-
247 config-daemon, /usr/sbin/printconf-backend, /usr/lib/udev/udev-
248 configure-printer, /usr/libexec/cups-pk-helper-mechanism
249 cupsd_config_var_run_t
252 - Set files with the cupsd_config_var_run_t type, if you want to store
254 the cupsd config files under the /run or /var/run directory.
255 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
265 semanage fcontext can also be used to manipulate default file context
266 mappings.
267 semanage permissive can also be used to manipulate whether or not a
269 process type is permissive.
270 semanage module can also be used to enable/disable/install/remove pol‐
272 icy modules.
273 semanage boolean can also be used to manipulate the booleans
275 system-config-selinux is a GUI tool available to customize SELinux pol‐
278 icy settings.
