6 cupsd_lpd_selinux - Security Enhanced Linux Policy for the cupsd_lpd
7 processes
8
10 Security-Enhanced Linux secures the cupsd_lpd processes via flexible
11 mandatory access control.
12 The cupsd_lpd processes execute with the cupsd_lpd_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep cupsd_lpd_t
20
24 The cupsd_lpd_t SELinux type can be entered via the cupsd_lpd_exec_t
25 file type.
26 The default entrypoint paths for the cupsd_lpd_t domain are the follow‐
28 ing:
29 /usr/lib/cups/daemon/cups-lpd
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 cupsd_lpd policy is very flexible allowing users to setup their
40 cupsd_lpd processes in as secure a method as possible.
41 The following process types are defined for cupsd_lpd:
43 cupsd_lpd_t
45 Note: semanage permissive -a cupsd_lpd_t can be used to make the
47 process type cupsd_lpd_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required.
54 cupsd_lpd policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run cupsd_lpd with the tightest
56 access possible.
57 If you want to allow all domains to execute in fips_mode, you must turn
61 on the fips_mode boolean. Enabled by default.
62 setsebool -P fips_mode 1
64
68 The SELinux process type cupsd_lpd_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

136 SELinux requires files to have an extended attribute to define the file
137 type.
138 You can see the context of a file using the -Z option to ls
140 Policy governs the access confined processes have to these files.
142 SELinux cupsd_lpd policy is very flexible allowing users to setup their
143 cupsd_lpd processes in as secure a method as possible.
144 STANDARD FILE CONTEXT
146 SELinux defines the file context types for the cupsd_lpd, if you wanted
148 to store files with these types in a diffent paths, you need to execute
149 the semanage command to specify alternate labeling and then use re‐
150 storecon to put the labels on disk.
151 semanage fcontext -a -t cupsd_lpd_var_run_t '/srv/mycupsd_lpd_con‐
153 tent(/.*)?'
154 restorecon -R -v /srv/mycupsd_lpd_content
155 Note: SELinux often uses regular expressions to specify labels that
157 match multiple files.
158 The following file types are defined for cupsd_lpd:
160 cupsd_lpd_exec_t
164 - Set files with the cupsd_lpd_exec_t type, if you want to transition
166 an executable to the cupsd_lpd_t domain.
167 cupsd_lpd_tmp_t
171 - Set files with the cupsd_lpd_tmp_t type, if you want to store cupsd
173 lpd temporary files in the /tmp directories.
174 cupsd_lpd_var_run_t
178 - Set files with the cupsd_lpd_var_run_t type, if you want to store the
180 cupsd lpd files under the /run or /var/run directory.
181 Note: File context can be temporarily modified with the chcon command.
185 If you want to permanently change the file context you need to use the
186 semanage fcontext command. This will modify the SELinux labeling data‐
187 base. You will need to use restorecon to apply the labels.
188
191 semanage fcontext can also be used to manipulate default file context
192 mappings.
193 semanage permissive can also be used to manipulate whether or not a
195 process type is permissive.
196 semanage module can also be used to enable/disable/install/remove pol‐
198 icy modules.
199 semanage boolean can also be used to manipulate the booleans
201 system-config-selinux is a GUI tool available to customize SELinux pol‐
204 icy settings.
