NAME

6       cupsd_lpd_selinux  -  Security  Enhanced Linux Policy for the cupsd_lpd
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the cupsd_lpd  processes  via  flexible
11       mandatory access control.
12
13       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
17       For example:
18
19       ps -eZ | grep cupsd_lpd_t
20

22

ENTRYPOINTS

24       The  cupsd_lpd_t  SELinux  type can be entered via the cupsd_lpd_exec_t
25       file type.
26
27       The default entrypoint paths for the cupsd_lpd_t domain are the follow‐
28       ing:
29
30       /usr/lib/cups/daemon/cups-lpd
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       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
42       The following process types are defined for cupsd_lpd:
43
44       cupsd_lpd_t
45
46       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
51

BOOLEANS

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
58
59
60       If you want to allow users to resolve user passwd entries directly from
61       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
62       gin_nsswitch_use_ldap boolean. Disabled by default.
63
64       setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to allow confined applications to run with kerberos, you
76       must turn on the kerberos_enabled boolean. Enabled by default.
77
78       setsebool -P kerberos_enabled 1
79
80
81
82       If you want to allow system to run with  NIS,  you  must  turn  on  the
83       nis_enabled boolean. Disabled by default.
84
85       setsebool -P nis_enabled 1
86
87
88
89       If  you  want to allow confined applications to use nscd shared memory,
90       you must turn on the nscd_use_shm boolean. Disabled by default.
91
92       setsebool -P nscd_use_shm 1

MANAGED FILES

97       The SELinux process type cupsd_lpd_t can manage files labeled with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.
100
101       cupsd_lpd_tmp_t
102
103
104       cupsd_lpd_var_run_t
105
106
107       print_spool_t
108
109            /var/spool/lpd(/.*)?
110            /var/spool/cups(/.*)?
111            /var/spool/cups-pdf(/.*)?
112
113

FILE CONTEXTS

115       SELinux requires files to have an extended attribute to define the file
116       type.
117
118       You can see the context of a file using the -Z option to ls
119
120       Policy  governs  the  access  confined  processes  have to these files.
121       SELinux cupsd_lpd policy is very flexible allowing users to setup their
122       cupsd_lpd processes in as secure a method as possible.
123
124       STANDARD FILE CONTEXT
125
126       SELinux defines the file context types for the cupsd_lpd, if you wanted
127       to store files with these types in a diffent paths, you need to execute
128       the  semanage  command  to  sepecify  alternate  labeling  and then use
129       restorecon to put the labels on disk.
130
131       semanage  fcontext  -a  -t  cupsd_lpd_var_run_t  '/srv/mycupsd_lpd_con‐
132       tent(/.*)?'
133       restorecon -R -v /srv/mycupsd_lpd_content
134
135       Note:  SELinux  often  uses  regular expressions to specify labels that
136       match multiple files.
137
138       The following file types are defined for cupsd_lpd:
139
140
141
142       cupsd_lpd_exec_t
143
144       - Set files with the cupsd_lpd_exec_t type, if you want  to  transition
145       an executable to the cupsd_lpd_t domain.
146
147
148
149       cupsd_lpd_tmp_t
150
151       -  Set  files with the cupsd_lpd_tmp_t type, if you want to store cupsd
152       lpd temporary files in the /tmp directories.
153
154
155
156       cupsd_lpd_var_run_t
157
158       - Set files with the cupsd_lpd_var_run_t type, if you want to store the
159       cupsd lpd files under the /run or /var/run directory.
160
161
162
163       Note:  File context can be temporarily modified with the chcon command.
164       If you want to permanently change the file context you need to use  the
165       semanage fcontext command.  This will modify the SELinux labeling data‐
166       base.  You will need to use restorecon to apply the labels.
167
168

COMMANDS

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