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 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

PORT TYPES

68       SELinux defines port types to represent TCP and UDP ports.
69
70       You  can  see  the  types associated with a port by using the following
71       command:
72
73       semanage port -l
74
75
76       Policy governs the access  confined  processes  have  to  these  ports.
77       SELinux memcached policy is very flexible allowing users to setup their
78       memcached processes in as secure a method as possible.
79
80       The following port types are defined for memcached:
81
82
83       memcache_port_t
84
85
86
87       Default Defined Ports:
88                 tcp 11211
89                 udp 11211
90

MANAGED FILES

92       The SELinux process type memcached_t can manage files labeled with  the
93       following file types.  The paths listed are the default paths for these
94       file types.  Note the processes UID still need to have DAC permissions.
95

FILE CONTEXTS

138       SELinux requires files to have an extended attribute to define the file
139       type.
140
141       You can see the context of a file using the -Z option to ls
142
143       Policy  governs  the  access  confined  processes  have to these files.
144       SELinux memcached policy is very flexible allowing users to setup their
145       memcached processes in as secure a method as possible.
146
147       STANDARD FILE CONTEXT
148
149       SELinux defines the file context types for the memcached, if you wanted
150       to store files with these types in a diffent paths, you need to execute
151       the  semanage  command  to  sepecify  alternate  labeling  and then use
152       restorecon to put the labels on disk.
153
154       semanage  fcontext  -a  -t  memcached_var_run_t  '/srv/mymemcached_con‐
155       tent(/.*)?'
156       restorecon -R -v /srv/mymemcached_content
157
158       Note:  SELinux  often  uses  regular expressions to specify labels that
159       match multiple files.
160
161       The following file types are defined for memcached:
162
163
164
165       memcached_exec_t
166
167       - Set files with the memcached_exec_t type, if you want  to  transition
168       an executable to the memcached_t domain.
169
170
171
172       memcached_initrc_exec_t
173
174       - Set files with the memcached_initrc_exec_t type, if you want to tran‐
175       sition an executable to the memcached_initrc_t domain.
176
177
178
179       memcached_var_run_t
180
181       - Set files with the memcached_var_run_t type, if you want to store the
182       memcached files under the /run or /var/run directory.
183
184
185       Paths:
186            /var/run/memcached(/.*)?, /var/run/ipa_memcached(/.*)?
187
188
189       Note:  File context can be temporarily modified with the chcon command.
190       If you want to permanently change the file context you need to use  the
191       semanage fcontext command.  This will modify the SELinux labeling data‐
192       base.  You will need to use restorecon to apply the labels.
193
194

COMMANDS

196       semanage fcontext can also be used to manipulate default  file  context
197       mappings.
198
199       semanage  permissive  can  also  be used to manipulate whether or not a
200       process type is permissive.
201
202       semanage module can also be used to enable/disable/install/remove  pol‐
203       icy modules.
204
205       semanage port can also be used to manipulate the port definitions
206
207       semanage boolean can also be used to manipulate the booleans
208
209
210       system-config-selinux is a GUI tool available to customize SELinux pol‐
211       icy settings.
