NAME

6       lpd_selinux - Security Enhanced Linux Policy for the lpd processes
7

DESCRIPTION

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

21

ENTRYPOINTS

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

PROCESS TYPES

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

BOOLEANS

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.
52
53
54
55       If you want to allow all domains to execute in fips_mode, you must turn
56       on the fips_mode boolean. Enabled by default.
57
58       setsebool -P fips_mode 1
59
60
61
62       If you want to allow system to run with  NIS,  you  must  turn  on  the
63       nis_enabled boolean. Disabled by default.
64
65       setsebool -P nis_enabled 1
66

MANAGED FILES

70       The  SELinux  process type lpd_t can manage files labeled with the fol‐
71       lowing file types.  The paths listed are the default  paths  for  these
72       file types.  Note the processes UID still need to have DAC permissions.

FILE CONTEXTS

122       SELinux requires files to have an extended attribute to define the file
123       type.
124
125       You can see the context of a file using the -Z option to ls
126
127       Policy governs the access  confined  processes  have  to  these  files.
128       SELinux  lpd  policy is very flexible allowing users to setup their lpd
129       processes in as secure a method as possible.
130
131       STANDARD FILE CONTEXT
132
133       SELinux defines the file context types for the lpd, if  you  wanted  to
134       store  files  with  these types in a diffent paths, you need to execute
135       the semanage command  to  sepecify  alternate  labeling  and  then  use
136       restorecon to put the labels on disk.
137
138       semanage fcontext -a -t lpd_var_run_t '/srv/mylpd_content(/.*)?'
139       restorecon -R -v /srv/mylpd_content
140
141       Note:  SELinux  often  uses  regular expressions to specify labels that
142       match multiple files.
143
144       The following file types are defined for lpd:
145
146
147
148       lpd_exec_t
149
150       - Set files with the lpd_exec_t type, if you want to transition an exe‐
151       cutable to the lpd_t domain.
152
153
154
155       lpd_tmp_t
156
157       - Set files with the lpd_tmp_t type, if you want to store lpd temporary
158       files in the /tmp directories.
159
160
161
162       lpd_var_run_t
163
164       - Set files with the lpd_var_run_t type, if you want to store  the  lpd
165       files under the /run or /var/run directory.
166
167
168       Paths:
169            /var/run/lprng(/.*)?, /var/spool/turboprint(/.*)?
170
171
172       Note:  File context can be temporarily modified with the chcon command.
173       If you want to permanently change the file context you need to use  the
174       semanage fcontext command.  This will modify the SELinux labeling data‐
175       base.  You will need to use restorecon to apply the labels.
176
177

COMMANDS

179       semanage fcontext can also be used to manipulate default  file  context
180       mappings.
181
182       semanage  permissive  can  also  be used to manipulate whether or not a
183       process type is permissive.
184
185       semanage module can also be used to enable/disable/install/remove  pol‐
186       icy modules.
187
188       semanage boolean can also be used to manipulate the booleans
189
190
191       system-config-selinux is a GUI tool available to customize SELinux pol‐
192       icy settings.
