NAME

6       memcached_selinux  -  Security  Enhanced Linux Policy for the memcached
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the memcached  processes  via  flexible
11       mandatory access control.
12
13       The  memcached processes execute with the memcached_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 memcached_t
20
21
22

ENTRYPOINTS

24       The  memcached_t  SELinux  type can be entered via the memcached_exec_t
25       file type.
26
27       The default entrypoint paths for the memcached_t domain are the follow‐
28       ing:
29
30       /usr/bin/memcached
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       memcached  policy  is  very flexible allowing users to setup their mem‐
40       cached processes in as secure a method as possible.
41
42       The following process types are defined for memcached:
43
44       memcached_t
45
46       Note: semanage permissive -a  memcached_t  can  be  used  to  make  the
47       process  type  memcached_t  permissive. SELinux does not deny access to
48       permissive process types, but the AVC (SELinux  denials)  messages  are
49       still generated.
50
51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  mem‐
54       cached policy is extremely flexible and has several booleans that allow
55       you to manipulate the policy and run memcached with the tightest access
56       possible.

PORT TYPES

171       SELinux defines port types to represent TCP and UDP ports.
172
173       You can see the types associated with a port  by  using  the  following
174       command:
175
176       semanage port -l
177
178
179       Policy  governs  the  access  confined  processes  have to these ports.
180       SELinux memcached policy is very flexible allowing users to setup their
181       memcached processes in as secure a method as possible.
182
183       The following port types are defined for memcached:
184
185
186       memcache_port_t
187
188
189
190       Default Defined Ports:
191                 tcp 11211
192                 udp 11211
193

MANAGED FILES

195       The  SELinux process type memcached_t can manage files labeled with the
196       following file types.  The paths listed are the default paths for these
197       file types.  Note the processes UID still need to have DAC permissions.
198

FILE CONTEXTS

241       SELinux requires files to have an extended attribute to define the file
242       type.
243
244       You can see the context of a file using the -Z option to ls
245
246       Policy governs the access  confined  processes  have  to  these  files.
247       SELinux memcached policy is very flexible allowing users to setup their
248       memcached processes in as secure a method as possible.
249
250       STANDARD FILE CONTEXT
251
252       SELinux defines the file context types for the memcached, if you wanted
253       to store files with these types in a diffent paths, you need to execute
254       the semanage command  to  sepecify  alternate  labeling  and  then  use
255       restorecon to put the labels on disk.
256
257       semanage  fcontext  -a  -t  memcached_var_run_t  '/srv/mymemcached_con‐
258       tent(/.*)?'
259       restorecon -R -v /srv/mymemcached_content
260
261       Note: SELinux often uses regular expressions  to  specify  labels  that
262       match multiple files.
263
264       The following file types are defined for memcached:
265
266
267
268       memcached_exec_t
269
270       -  Set  files with the memcached_exec_t type, if you want to transition
271       an executable to the memcached_t domain.
272
273
274
275       memcached_initrc_exec_t
276
277       - Set files with the memcached_initrc_exec_t type, if you want to tran‐
278       sition an executable to the memcached_initrc_t domain.
279
280
281
282       memcached_var_run_t
283
284       - Set files with the memcached_var_run_t type, if you want to store the
285       memcached files under the /run or /var/run directory.
286
287
288       Paths:
289            /var/run/memcached(/.*)?, /var/run/ipa_memcached(/.*)?
290
291
292       Note: File context can be temporarily modified with the chcon  command.
293       If  you want to permanently change the file context you need to use the
294       semanage fcontext command.  This will modify the SELinux labeling data‐
295       base.  You will need to use restorecon to apply the labels.
296
297

COMMANDS

299       semanage  fcontext  can also be used to manipulate default file context
300       mappings.
301
302       semanage permissive can also be used to manipulate  whether  or  not  a
303       process type is permissive.
304
305       semanage  module can also be used to enable/disable/install/remove pol‐
306       icy modules.
307
308       semanage port can also be used to manipulate the port definitions
309
310       semanage boolean can also be used to manipulate the booleans
311
312
313       system-config-selinux is a GUI tool available to customize SELinux pol‐
314       icy settings.
