NAME

6       lpr_selinux - Security Enhanced Linux Policy for the lpr processes
7

DESCRIPTION

9       Security-Enhanced  Linux  secures the lpr processes via flexible manda‐
10       tory access control.
11
12       The lpr processes execute with the lpr_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 lpr_t
19

21

ENTRYPOINTS

23       The lpr_t SELinux type can be entered via the lpr_exec_t file type.
24
25       The default entrypoint paths for the lpr_t domain are the following:
26
27       /usr/bin/lp(.cups)?,    /usr/bin/lpq(.cups)?,     /usr/bin/lpr(.cups)?,
28       /usr/bin/lprm(.cups)?,  /usr/sbin/lpc(.cups)?, /usr/bin/cancel(.cups)?,
29       /usr/bin/lpstat(.cups)?,     /opt/gutenprint/bin(/.*)?,     /opt/guten‐
30       print/sbin(/.*)?,     /usr/linuxprinter/bin/l?lpr,    /usr/local/linux‐
31       printer/bin/l?lpr,  /usr/sbin/accept,  /usr/sbin/lpinfo,  /usr/sbin/lp‐
32       move, /usr/sbin/lpadmin, /usr/bin/lpoptions
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       lpr policy is very flexible allowing users to setup their lpr processes
42       in as secure a method as possible.
43
44       The following process types are defined for lpr:
45
46       lpr_t
47
48       Note: semanage permissive -a lpr_t can be used to make the process type
49       lpr_t  permissive.  SELinux  does not deny access to permissive process
50       types, but the AVC (SELinux denials) messages are still generated.
51
52

BOOLEANS

54       SELinux policy is customizable based on  least  access  required.   lpr
55       policy is extremely flexible and has several booleans that allow you to
56       manipulate the policy and run lpr with the tightest access possible.
57
58
59
60       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
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to  allow  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1
71
72
73
74       If you want to determine whether to support lpd server, you  must  turn
75       on the use_lpd_server boolean. Disabled by default.
76
77       setsebool -P use_lpd_server 1

MANAGED FILES

82       The  SELinux  process type lpr_t can manage files labeled with the fol‐
83       lowing file types.  The paths listed are the default  paths  for  these
84       file types.  Note the processes UID still need to have DAC permissions.
85
86       insights_client_tmp_t
87
88            /var/tmp/insights-client(/.*)?
89            /tmp/insights-client.ppid
90            /var/tmp/insights-client.ppid
91
92       krb5_host_rcache_t
93
94            /var/tmp/krb5_0.rcache2
95            /var/cache/krb5rcache(/.*)?

FILE CONTEXTS

117       SELinux requires files to have an extended attribute to define the file
118       type.
119
120       You can see the context of a file using the -Z option to ls
121
122       Policy governs the access  confined  processes  have  to  these  files.
123       SELinux  lpr  policy is very flexible allowing users to setup their lpr
124       processes in as secure a method as possible.
125
126       STANDARD FILE CONTEXT
127
128       SELinux defines the file context types for the lpr, if  you  wanted  to
129       store  files with these types in a different paths, you need to execute
130       the semanage command to specify alternate labeling  and  then  use  re‐
131       storecon to put the labels on disk.
132
133       semanage fcontext -a -t lpr_exec_t '/srv/lpr/content(/.*)?'
134       restorecon -R -v /srv/mylpr_content
135
136       Note:  SELinux  often  uses  regular expressions to specify labels that
137       match multiple files.
138
139       The following file types are defined for lpr:
140
141
142
143       lpr_exec_t
144
145       - Set files with the lpr_exec_t type, if you want to transition an exe‐
146       cutable to the lpr_t domain.
147
148
149       Paths:
150            /usr/bin/lp(.cups)?,  /usr/bin/lpq(.cups)?,  /usr/bin/lpr(.cups)?,
151            /usr/bin/lprm(.cups)?,    /usr/sbin/lpc(.cups)?,     /usr/bin/can‐
152            cel(.cups)?,  /usr/bin/lpstat(.cups)?,  /opt/gutenprint/bin(/.*)?,
153            /opt/gutenprint/sbin(/.*)?, /usr/linuxprinter/bin/l?lpr,  /usr/lo‐
154            cal/linuxprinter/bin/l?lpr,   /usr/sbin/accept,  /usr/sbin/lpinfo,
155            /usr/sbin/lpmove, /usr/sbin/lpadmin, /usr/bin/lpoptions
156
157
158       lpr_tmp_t
159
160       - Set files with the lpr_tmp_t type, if you want to store lpr temporary
161       files in the /tmp directories.
162
163
164
165       Note:  File context can be temporarily modified with the chcon command.
166       If you want to permanently change the file context you need to use  the
167       semanage fcontext command.  This will modify the SELinux labeling data‐
168       base.  You will need to use restorecon to apply the labels.
169
170

COMMANDS

172       semanage fcontext can also be used to manipulate default  file  context
173       mappings.
174
175       semanage  permissive  can  also  be used to manipulate whether or not a
176       process type is permissive.
177
178       semanage module can also be used to enable/disable/install/remove  pol‐
179       icy modules.
180
181       semanage boolean can also be used to manipulate the booleans
182
183
184       system-config-selinux is a GUI tool available to customize SELinux pol‐
185       icy settings.
