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 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 For example:
17 ps -eZ | grep lpd_t
19
23 The lpd_t SELinux type can be entered via the lpd_exec_t file type.
24 The default entrypoint paths for the lpd_t domain are the following:
26 /usr/sbin/lpd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 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 The following process types are defined for lpd:
40 lpd_t
42 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
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 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 setsebool -P fips_mode 1
59 If you want to allow system to run with NIS, you must turn on the
63 nis_enabled boolean. Disabled by default.
64 setsebool -P nis_enabled 1
66
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.

126 SELinux requires files to have an extended attribute to define the file
127 type.
128 You can see the context of a file using the -Z option to ls
130 Policy governs the access confined processes have to these files.
132 SELinux lpd policy is very flexible allowing users to setup their lpd
133 processes in as secure a method as possible.
134 STANDARD FILE CONTEXT
136 SELinux defines the file context types for the lpd, if you wanted to
138 store files with these types in a diffent paths, you need to execute
139 the semanage command to sepecify alternate labeling and then use re‐
140 storecon to put the labels on disk.
141 semanage fcontext -a -t lpd_var_run_t '/srv/mylpd_content(/.*)?'
143 restorecon -R -v /srv/mylpd_content
144 Note: SELinux often uses regular expressions to specify labels that
146 match multiple files.
147 The following file types are defined for lpd:
149 lpd_exec_t
153 - Set files with the lpd_exec_t type, if you want to transition an exe‐
155 cutable to the lpd_t domain.
156 lpd_tmp_t
160 - Set files with the lpd_tmp_t type, if you want to store lpd temporary
162 files in the /tmp directories.
163 lpd_var_run_t
167 - Set files with the lpd_var_run_t type, if you want to store the lpd
169 files under the /run or /var/run directory.
170 Paths:
173 /var/run/lprng(/.*)?, /var/spool/turboprint(/.*)?
174 Note: File context can be temporarily modified with the chcon command.
177 If you want to permanently change the file context you need to use the
178 semanage fcontext command. This will modify the SELinux labeling data‐
179 base. You will need to use restorecon to apply the labels.
180
183 semanage fcontext can also be used to manipulate default file context
184 mappings.
185 semanage permissive can also be used to manipulate whether or not a
187 process type is permissive.
188 semanage module can also be used to enable/disable/install/remove pol‐
190 icy modules.
191 semanage boolean can also be used to manipulate the booleans
193 system-config-selinux is a GUI tool available to customize SELinux pol‐
196 icy settings.
