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‐

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

279 SELinux requires files to have an extended attribute to define the file
280 type.
281 You can see the context of a file using the -Z option to ls
283 Policy governs the access confined processes have to these files.
285 SELinux cupsd_config policy is very flexible allowing users to setup
286 their cupsd_config processes in as secure a method as possible.
287 STANDARD FILE CONTEXT
289 SELinux defines the file context types for the cupsd_config, if you
291 wanted to store files with these types in a diffent paths, you need to
292 execute the semanage command to sepecify alternate labeling and then
293 use restorecon to put the labels on disk.
294 semanage fcontext -a -t cupsd_config_var_run_t '/srv/mycupsd_con‐
296 fig_content(/.*)?'
297 restorecon -R -v /srv/mycupsd_config_content
298 Note: SELinux often uses regular expressions to specify labels that
300 match multiple files.
301 The following file types are defined for cupsd_config:
303 cupsd_config_exec_t
307 - Set files with the cupsd_config_exec_t type, if you want to transi‐
309 tion an executable to the cupsd_config_t domain.
310 Paths:
313 /usr/sbin/hal_lpadmin, /usr/libexec/hal_lpadmin, /usr/bin/cups-
314 config-daemon, /usr/sbin/printconf-backend, /usr/lib/udev/udev-
315 configure-printer, /usr/libexec/cups-pk-helper-mechanism
316 cupsd_config_var_run_t
319 - Set files with the cupsd_config_var_run_t type, if you want to store
321 the cupsd config files under the /run or /var/run directory.
322 Note: File context can be temporarily modified with the chcon command.
326 If you want to permanently change the file context you need to use the
327 semanage fcontext command. This will modify the SELinux labeling data‐
328 base. You will need to use restorecon to apply the labels.
329
332 semanage fcontext can also be used to manipulate default file context
333 mappings.
334 semanage permissive can also be used to manipulate whether or not a
336 process type is permissive.
337 semanage module can also be used to enable/disable/install/remove pol‐
339 icy modules.
340 semanage boolean can also be used to manipulate the booleans
342 system-config-selinux is a GUI tool available to customize SELinux pol‐
345 icy settings.
