6 cups_pdf_selinux - Security Enhanced Linux Policy for the cups_pdf pro‐
7 cesses
8
10 Security-Enhanced Linux secures the cups_pdf processes via flexible
11 mandatory access control.
12
13 The cups_pdf processes execute with the cups_pdf_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 cups_pdf_t
20
21
22
24 The cups_pdf_t SELinux type can be entered via the cups_pdf_exec_t file
25 type.
26
27 The default entrypoint paths for the cups_pdf_t domain are the follow‐
28 ing:
29
30 /usr/lib/cups/backend/cups-pdf
31
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 cups_pdf policy is very flexible allowing users to setup their cups_pdf
40 processes in as secure a method as possible.
41
42 The following process types are defined for cups_pdf:
43
44 cups_pdf_t
45
46 Note: semanage permissive -a cups_pdf_t can be used to make the process
47 type cups_pdf_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required.
54 cups_pdf policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run cups_pdf 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. Enabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
96 If you want to support NFS home directories, you must turn on the
97 use_nfs_home_dirs boolean. Disabled by default.
98
99 setsebool -P use_nfs_home_dirs 1
100
101
102
104 The SELinux process type cups_pdf_t can manage files labeled with the
105 following file types. The paths listed are the default paths for these
106 file types. Note the processes UID still need to have DAC permissions.

141 SELinux requires files to have an extended attribute to define the file
142 type.
143
144 You can see the context of a file using the -Z option to ls
145
146 Policy governs the access confined processes have to these files.
147 SELinux cups_pdf policy is very flexible allowing users to setup their
148 cups_pdf processes in as secure a method as possible.
149
150 STANDARD FILE CONTEXT
151
152 SELinux defines the file context types for the cups_pdf, if you wanted
153 to store files with these types in a diffent paths, you need to execute
154 the semanage command to sepecify alternate labeling and then use
155 restorecon to put the labels on disk.
156
157 semanage fcontext -a -t cups_pdf_tmp_t '/srv/mycups_pdf_content(/.*)?'
158 restorecon -R -v /srv/mycups_pdf_content
159
160 Note: SELinux often uses regular expressions to specify labels that
161 match multiple files.
162
163 The following file types are defined for cups_pdf:
164
165
166
167 cups_pdf_exec_t
168
169 - Set files with the cups_pdf_exec_t type, if you want to transition an
170 executable to the cups_pdf_t domain.
171
172
173
174 cups_pdf_tmp_t
175
176 - Set files with the cups_pdf_tmp_t type, if you want to store cups pdf
177 temporary files in the /tmp directories.
178
179
180
181 Note: File context can be temporarily modified with the chcon command.
182 If you want to permanently change the file context you need to use the
183 semanage fcontext command. This will modify the SELinux labeling data‐
184 base. You will need to use restorecon to apply the labels.
185
186
188 semanage fcontext can also be used to manipulate default file context
189 mappings.
190
191 semanage permissive can also be used to manipulate whether or not a
192 process type is permissive.
193
194 semanage module can also be used to enable/disable/install/remove pol‐
195 icy modules.
196
197 semanage boolean can also be used to manipulate the booleans
198
199
200 system-config-selinux is a GUI tool available to customize SELinux pol‐
201 icy settings.
