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
68 The SELinux process type cups_pdf_t can manage files labeled with the
69 following file types. The paths listed are the default paths for these
70 file types. Note the processes UID still need to have DAC permissions.

116 SELinux requires files to have an extended attribute to define the file
117 type.
118
119 You can see the context of a file using the -Z option to ls
120
121 Policy governs the access confined processes have to these files.
122 SELinux cups_pdf policy is very flexible allowing users to setup their
123 cups_pdf processes in as secure a method as possible.
124
125 STANDARD FILE CONTEXT
126
127 SELinux defines the file context types for the cups_pdf, if you wanted
128 to store files with these types in a diffent paths, you need to execute
129 the semanage command to specify alternate labeling and then use re‐
130 storecon to put the labels on disk.
131
132 semanage fcontext -a -t cups_pdf_tmp_t '/srv/mycups_pdf_content(/.*)?'
133 restorecon -R -v /srv/mycups_pdf_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 cups_pdf:
139
140
141
142 cups_pdf_exec_t
143
144 - Set files with the cups_pdf_exec_t type, if you want to transition an
145 executable to the cups_pdf_t domain.
146
147
148
149 cups_pdf_tmp_t
150
151 - Set files with the cups_pdf_tmp_t type, if you want to store cups pdf
152 temporary files in the /tmp directories.
153
154
155
156 Note: File context can be temporarily modified with the chcon command.
157 If you want to permanently change the file context you need to use the
158 semanage fcontext command. This will modify the SELinux labeling data‐
159 base. You will need to use restorecon to apply the labels.
160
161
163 semanage fcontext can also be used to manipulate default file context
164 mappings.
165
166 semanage permissive can also be used to manipulate whether or not a
167 process type is permissive.
168
169 semanage module can also be used to enable/disable/install/remove pol‐
170 icy modules.
171
172 semanage boolean can also be used to manipulate the booleans
173
174
175 system-config-selinux is a GUI tool available to customize SELinux pol‐
176 icy settings.
