NAME

6       varnishd_selinux - Security Enhanced Linux Policy for the varnishd pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

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

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       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

BOOLEANS

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

PORT TYPES

178       SELinux defines port types to represent TCP and UDP ports.
179
180       You  can  see  the  types associated with a port by using the following
181       command:
182
183       semanage port -l
184
185
186       Policy governs the access  confined  processes  have  to  these  ports.
187       SELinux  varnishd policy is very flexible allowing users to setup their
188       varnishd processes in as secure a method as possible.
189
190       The following port types are defined for varnishd:
191
192
193       varnishd_port_t
194
195
196
197       Default Defined Ports:
198                 tcp 6081-6082
199

MANAGED FILES

201       The SELinux process type varnishd_t can manage files labeled  with  the
202       following file types.  The paths listed are the default paths for these
203       file types.  Note the processes UID still need to have DAC permissions.
204
205       cluster_conf_t

FILE CONTEXTS

253       SELinux requires files to have an extended attribute to define the file
254       type.
255
256       You can see the context of a file using the -Z option to ls
257
258       Policy  governs  the  access  confined  processes  have to these files.
259       SELinux varnishd policy is very flexible allowing users to setup  their
260       varnishd processes in as secure a method as possible.
261
262       STANDARD FILE CONTEXT
263
264       SELinux  defines the file context types for the varnishd, if you wanted
265       to store files with these types in a diffent paths, you need to execute
266       the  semanage  command  to  sepecify  alternate  labeling  and then use
267       restorecon to put the labels on disk.
268
269       semanage  fcontext  -a  -t   varnishd_var_run_t   '/srv/myvarnishd_con‐
270       tent(/.*)?'
271       restorecon -R -v /srv/myvarnishd_content
272
273       Note:  SELinux  often  uses  regular expressions to specify labels that
274       match multiple files.
275
276       The following file types are defined for varnishd:
277
278
279
280       varnishd_etc_t
281
282       - Set files with the varnishd_etc_t type, if you want to store varnishd
283       files in the /etc directories.
284
285
286
287       varnishd_exec_t
288
289       - Set files with the varnishd_exec_t type, if you want to transition an
290       executable to the varnishd_t domain.
291
292
293
294       varnishd_initrc_exec_t
295
296       - Set files with the varnishd_initrc_exec_t type, if you want to  tran‐
297       sition an executable to the varnishd_initrc_t domain.
298
299
300
301       varnishd_tmp_t
302
303       - Set files with the varnishd_tmp_t type, if you want to store varnishd
304       temporary files in the /tmp directories.
305
306
307
308       varnishd_var_lib_t
309
310       - Set files with the varnishd_var_lib_t type, if you want to store  the
311       varnishd files under the /var/lib directory.
312
313
314
315       varnishd_var_run_t
316
317       -  Set files with the varnishd_var_run_t type, if you want to store the
318       varnishd files under the /run or /var/run directory.
319
320
321
322       Note: File context can be temporarily modified with the chcon  command.
323       If  you want to permanently change the file context you need to use the
324       semanage fcontext command.  This will modify the SELinux labeling data‐
325       base.  You will need to use restorecon to apply the labels.
326
327

COMMANDS

329       semanage  fcontext  can also be used to manipulate default file context
330       mappings.
331
332       semanage permissive can also be used to manipulate  whether  or  not  a
333       process type is permissive.
334
335       semanage  module can also be used to enable/disable/install/remove pol‐
336       icy modules.
337
338       semanage port can also be used to manipulate the port definitions
339
340       semanage boolean can also be used to manipulate the booleans
341
342
343       system-config-selinux is a GUI tool available to customize SELinux pol‐
344       icy settings.
