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.
57
58
59
60       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
61       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
62       Enabled by default.
63
64       setsebool -P daemons_dontaudit_scheduling 1
65
66
67
68       If you want to allow all domains to execute in fips_mode, you must turn
69       on the fips_mode boolean. Enabled by default.
70
71       setsebool -P fips_mode 1
72
73
74
75       If  you  want  to  allow  system  to run with NIS, you must turn on the
76       nis_enabled boolean. Disabled by default.
77
78       setsebool -P nis_enabled 1
79
80
81

PORT TYPES

83       SELinux defines port types to represent TCP and UDP ports.
84
85       You can see the types associated with a port  by  using  the  following
86       command:
87
88       semanage port -l
89
90
91       Policy  governs  the  access  confined  processes  have to these ports.
92       SELinux memcached policy is very flexible allowing users to setup their
93       memcached processes in as secure a method as possible.
94
95       The following port types are defined for memcached:
96
97
98       memcache_port_t
99
100
101
102       Default Defined Ports:
103                 tcp 11211
104                 udp 11211
105

MANAGED FILES

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

FILE CONTEXTS

168       SELinux requires files to have an extended attribute to define the file
169       type.
170
171       You can see the context of a file using the -Z option to ls
172
173       Policy governs the access  confined  processes  have  to  these  files.
174       SELinux memcached policy is very flexible allowing users to setup their
175       memcached processes in as secure a method as possible.
176
177       STANDARD FILE CONTEXT
178
179       SELinux defines the file context types for the memcached, if you wanted
180       to  store files with these types in a different paths, you need to exe‐
181       cute the semanage command to specify alternate labeling  and  then  use
182       restorecon to put the labels on disk.
183
184       semanage fcontext -a -t memcached_exec_t '/srv/memcached/content(/.*)?'
185       restorecon -R -v /srv/mymemcached_content
186
187       Note:  SELinux  often  uses  regular expressions to specify labels that
188       match multiple files.
189
190       The following file types are defined for memcached:
191
192
193
194       memcached_exec_t
195
196       - Set files with the memcached_exec_t type, if you want  to  transition
197       an executable to the memcached_t domain.
198
199
200
201       memcached_initrc_exec_t
202
203       - Set files with the memcached_initrc_exec_t type, if you want to tran‐
204       sition an executable to the memcached_initrc_t domain.
205
206
207
208       memcached_var_run_t
209
210       - Set files with the memcached_var_run_t type, if you want to store the
211       memcached files under the /run or /var/run directory.
212
213
214       Paths:
215            /var/run/memcached(/.*)?, /var/run/ipa_memcached(/.*)?
216
217
218       Note:  File context can be temporarily modified with the chcon command.
219       If you want to permanently change the file context you need to use  the
220       semanage fcontext command.  This will modify the SELinux labeling data‐
221       base.  You will need to use restorecon to apply the labels.
222
223

COMMANDS

225       semanage fcontext can also be used to manipulate default  file  context
226       mappings.
227
228       semanage  permissive  can  also  be used to manipulate whether or not a
229       process type is permissive.
230
231       semanage module can also be used to enable/disable/install/remove  pol‐
232       icy modules.
233
234       semanage port can also be used to manipulate the port definitions
235
236       semanage boolean can also be used to manipulate the booleans
237
238
239       system-config-selinux is a GUI tool available to customize SELinux pol‐
240       icy settings.
