6 memcached_selinux - Security Enhanced Linux Policy for the memcached
7 processes
8
10 Security-Enhanced Linux secures the memcached processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep memcached_t
20
24 The memcached_t SELinux type can be entered via the memcached_exec_t
25 file type.
26 The default entrypoint paths for the memcached_t domain are the follow‐
28 ing:
29 /usr/bin/memcached
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 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 The following process types are defined for memcached:
43 memcached_t
45 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
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 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.

147 you must turn on the nscd_use_shm boolean. Enabled by default.
148 setsebool -P nscd_use_shm 1
150
154 SELinux defines port types to represent TCP and UDP ports.
155 You can see the types associated with a port by using the following
157 command:
158 semanage port -l
160 Policy governs the access confined processes have to these ports.
163 SELinux memcached policy is very flexible allowing users to setup their
164 memcached processes in as secure a method as possible.
165 The following port types are defined for memcached:
167 memcache_port_t
170 Default Defined Ports:
174 tcp 11211
175 udp 11211
176
178 The SELinux process type memcached_t can manage files labeled with the
179 following file types. The paths listed are the default paths for these
180 file types. Note the processes UID still need to have DAC permissions.
181 cluster_conf_t
183 /etc/cluster(/.*)?
185 cluster_var_lib_t

246 SELinux requires files to have an extended attribute to define the file
247 type.
248 You can see the context of a file using the -Z option to ls
250 Policy governs the access confined processes have to these files.
252 SELinux memcached policy is very flexible allowing users to setup their
253 memcached processes in as secure a method as possible.
254 STANDARD FILE CONTEXT
256 SELinux defines the file context types for the memcached, if you wanted
258 to store files with these types in a diffent paths, you need to execute
259 the semanage command to sepecify alternate labeling and then use
260 restorecon to put the labels on disk.
261 semanage fcontext -a -t memcached_var_run_t '/srv/mymemcached_con‐
263 tent(/.*)?'
264 restorecon -R -v /srv/mymemcached_content
265 Note: SELinux often uses regular expressions to specify labels that
267 match multiple files.
268 The following file types are defined for memcached:
270 memcached_exec_t
274 - Set files with the memcached_exec_t type, if you want to transition
276 an executable to the memcached_t domain.
277 memcached_initrc_exec_t
281 - Set files with the memcached_initrc_exec_t type, if you want to tran‐
283 sition an executable to the memcached_initrc_t domain.
284 memcached_var_run_t
288 - Set files with the memcached_var_run_t type, if you want to store the
290 memcached files under the /run or /var/run directory.
291 Paths:
294 /var/run/memcached(/.*)?, /var/run/ipa_memcached(/.*)?
295 Note: File context can be temporarily modified with the chcon command.
298 If you want to permanently change the file context you need to use the
299 semanage fcontext command. This will modify the SELinux labeling data‐
300 base. You will need to use restorecon to apply the labels.
301
304 semanage fcontext can also be used to manipulate default file context
305 mappings.
306 semanage permissive can also be used to manipulate whether or not a
308 process type is permissive.
309 semanage module can also be used to enable/disable/install/remove pol‐
311 icy modules.
312 semanage port can also be used to manipulate the port definitions
314 semanage boolean can also be used to manipulate the booleans
316 system-config-selinux is a GUI tool available to customize SELinux pol‐
319 icy settings.
