6 varnishd_selinux - Security Enhanced Linux Policy for the varnishd pro‐
7 cesses
8
10 Security-Enhanced Linux secures the varnishd processes via flexible
11 mandatory access control.
12
13 The varnishd processes execute with the varnishd_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 varnishd_t
20
21
22
24 The varnishd_t SELinux type can be entered via the varnishd_exec_t file
25 type.
26
27 The default entrypoint paths for the varnishd_t domain are the follow‐
28 ing:
29
30 /usr/sbin/varnishd
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 varnishd policy is very flexible allowing users to setup their varnishd
40 processes in as secure a method as possible.
41
42 The following process types are defined for varnishd:
43
44 varnishd_t
45
46 Note: semanage permissive -a varnishd_t can be used to make the process
47 type varnishd_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. var‐
54 nishd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run varnishd with the tightest access
56 possible.
57
58
59
60 If you want to determine whether varnishd can use the full TCP network,
61 you must turn on the varnishd_connect_any boolean. Disabled by default.
62
63 setsebool -P varnishd_connect_any 1
64
65
66
67 If you want to allow all domains to execute in fips_mode, you must turn
68 on the fips_mode boolean. Enabled by default.
69
70 setsebool -P fips_mode 1
71
72
73
75 SELinux defines port types to represent TCP and UDP ports.
76
77 You can see the types associated with a port by using the following
78 command:
79
80 semanage port -l
81
82
83 Policy governs the access confined processes have to these ports.
84 SELinux varnishd policy is very flexible allowing users to setup their
85 varnishd processes in as secure a method as possible.
86
87 The following port types are defined for varnishd:
88
89
90 varnishd_port_t
91
92
93
94 Default Defined Ports:
95 tcp 6081-6082
96
98 The SELinux process type varnishd_t can manage files labeled with the
99 following file types. The paths listed are the default paths for these
100 file types. Note the processes UID still need to have DAC permissions.

165 SELinux requires files to have an extended attribute to define the file
166 type.
167
168 You can see the context of a file using the -Z option to ls
169
170 Policy governs the access confined processes have to these files.
171 SELinux varnishd policy is very flexible allowing users to setup their
172 varnishd processes in as secure a method as possible.
173
174 STANDARD FILE CONTEXT
175
176 SELinux defines the file context types for the varnishd, if you wanted
177 to store files with these types in a diffent paths, you need to execute
178 the semanage command to specify alternate labeling and then use re‐
179 storecon to put the labels on disk.
180
181 semanage fcontext -a -t varnishd_var_run_t '/srv/myvarnishd_con‐
182 tent(/.*)?'
183 restorecon -R -v /srv/myvarnishd_content
184
185 Note: SELinux often uses regular expressions to specify labels that
186 match multiple files.
187
188 The following file types are defined for varnishd:
189
190
191
192 varnishd_etc_t
193
194 - Set files with the varnishd_etc_t type, if you want to store varnishd
195 files in the /etc directories.
196
197
198
199 varnishd_exec_t
200
201 - Set files with the varnishd_exec_t type, if you want to transition an
202 executable to the varnishd_t domain.
203
204
205
206 varnishd_initrc_exec_t
207
208 - Set files with the varnishd_initrc_exec_t type, if you want to tran‐
209 sition an executable to the varnishd_initrc_t domain.
210
211
212
213 varnishd_tmp_t
214
215 - Set files with the varnishd_tmp_t type, if you want to store varnishd
216 temporary files in the /tmp directories.
217
218
219
220 varnishd_var_lib_t
221
222 - Set files with the varnishd_var_lib_t type, if you want to store the
223 varnishd files under the /var/lib directory.
224
225
226
227 varnishd_var_run_t
228
229 - Set files with the varnishd_var_run_t type, if you want to store the
230 varnishd files under the /run or /var/run directory.
231
232
233
234 Note: File context can be temporarily modified with the chcon command.
235 If you want to permanently change the file context you need to use the
236 semanage fcontext command. This will modify the SELinux labeling data‐
237 base. You will need to use restorecon to apply the labels.
238
239
241 semanage fcontext can also be used to manipulate default file context
242 mappings.
243
244 semanage permissive can also be used to manipulate whether or not a
245 process type is permissive.
246
247 semanage module can also be used to enable/disable/install/remove pol‐
248 icy modules.
249
250 semanage port can also be used to manipulate the port definitions
251
252 semanage boolean can also be used to manipulate the booleans
253
254
255 system-config-selinux is a GUI tool available to customize SELinux pol‐
256 icy settings.
