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 al‐
55 low you to manipulate the policy and run cups_pdf with the tightest ac‐
56 cess 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
75 The SELinux process type cups_pdf_t can manage files labeled with the
76 following file types. The paths listed are the default paths for these
77 file types. Note the processes UID still need to have DAC permissions.

123 SELinux requires files to have an extended attribute to define the file
124 type.
125
126 You can see the context of a file using the -Z option to ls
127
128 Policy governs the access confined processes have to these files.
129 SELinux cups_pdf policy is very flexible allowing users to setup their
130 cups_pdf processes in as secure a method as possible.
131
132 STANDARD FILE CONTEXT
133
134 SELinux defines the file context types for the cups_pdf, if you wanted
135 to store files with these types in a different paths, you need to exe‐
136 cute the semanage command to specify alternate labeling and then use
137 restorecon to put the labels on disk.
138
139 semanage fcontext -a -t cups_pdf_exec_t '/srv/cups_pdf/content(/.*)?'
140 restorecon -R -v /srv/mycups_pdf_content
141
142 Note: SELinux often uses regular expressions to specify labels that
143 match multiple files.
144
145 The following file types are defined for cups_pdf:
146
147
148
149 cups_pdf_exec_t
150
151 - Set files with the cups_pdf_exec_t type, if you want to transition an
152 executable to the cups_pdf_t domain.
153
154
155
156 cups_pdf_tmp_t
157
158 - Set files with the cups_pdf_tmp_t type, if you want to store cups pdf
159 temporary files in the /tmp directories.
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
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.
