6 lpd_selinux - Security Enhanced Linux Policy for the lpd processes
7
9 Security-Enhanced Linux secures the lpd processes via flexible manda‐
10 tory access control.
11
12 The lpd processes execute with the lpd_t SELinux type. You can check if
13 you have these processes running by executing the ps command with the
14 -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep lpd_t
19
20
21
23 The lpd_t SELinux type can be entered via the lpd_exec_t file type.
24
25 The default entrypoint paths for the lpd_t domain are the following:
26
27 /usr/sbin/lpd
28
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 lpd policy is very flexible allowing users to setup their lpd processes
37 in as secure a method as possible.
38
39 The following process types are defined for lpd:
40
41 lpd_t
42
43 Note: semanage permissive -a lpd_t can be used to make the process type
44 lpd_t permissive. SELinux does not deny access to permissive process
45 types, but the AVC (SELinux denials) messages are still generated.
46
47
49 SELinux policy is customizable based on least access required. lpd
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run lpd with the tightest access possible.

55 If you want to dontaudit all daemons scheduling requests (setsched,
56 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
57 Enabled by default.
58
59 setsebool -P daemons_dontaudit_scheduling 1
60
61
62
63 If you want to allow all domains to execute in fips_mode, you must turn
64 on the fips_mode boolean. Enabled by default.
65
66 setsebool -P fips_mode 1
67
68
69
70 If you want to allow system to run with NIS, you must turn on the
71 nis_enabled boolean. Disabled by default.
72
73 setsebool -P nis_enabled 1
74
75
76
78 The SELinux process type lpd_t can manage files labeled with the fol‐
79 lowing file types. The paths listed are the default paths for these
80 file types. Note the processes UID still need to have DAC permissions.

134 SELinux requires files to have an extended attribute to define the file
135 type.
136
137 You can see the context of a file using the -Z option to ls
138
139 Policy governs the access confined processes have to these files.
140 SELinux lpd policy is very flexible allowing users to setup their lpd
141 processes in as secure a method as possible.
142
143 STANDARD FILE CONTEXT
144
145 SELinux defines the file context types for the lpd, if you wanted to
146 store files with these types in a different paths, you need to execute
147 the semanage command to specify alternate labeling and then use re‐
148 storecon to put the labels on disk.
149
150 semanage fcontext -a -t lpd_exec_t '/srv/lpd/content(/.*)?'
151 restorecon -R -v /srv/mylpd_content
152
153 Note: SELinux often uses regular expressions to specify labels that
154 match multiple files.
155
156 The following file types are defined for lpd:
157
158
159
160 lpd_exec_t
161
162 - Set files with the lpd_exec_t type, if you want to transition an exe‐
163 cutable to the lpd_t domain.
164
165
166
167 lpd_tmp_t
168
169 - Set files with the lpd_tmp_t type, if you want to store lpd temporary
170 files in the /tmp directories.
171
172
173
174 lpd_var_run_t
175
176 - Set files with the lpd_var_run_t type, if you want to store the lpd
177 files under the /run or /var/run directory.
178
179
180 Paths:
181 /var/run/lprng(/.*)?, /var/spool/turboprint(/.*)?
182
183
184 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
189
191 semanage fcontext can also be used to manipulate default file context
192 mappings.
193
194 semanage permissive can also be used to manipulate whether or not a
195 process type is permissive.
196
197 semanage module can also be used to enable/disable/install/remove pol‐
198 icy modules.
199
200 semanage boolean can also be used to manipulate the booleans
201
202
203 system-config-selinux is a GUI tool available to customize SELinux pol‐
204 icy settings.
