6 puppetagent_selinux - Security Enhanced Linux Policy for the puppeta‐
7 gent processes
8
10 Security-Enhanced Linux secures the puppetagent processes via flexible
11 mandatory access control.
12 The puppetagent processes execute with the puppetagent_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16 For example:
18 ps -eZ | grep puppetagent_t
20
24 The puppetagent_t SELinux type can be entered via the puppeta‐
25 gent_exec_t file type.
26 The default entrypoint paths for the puppetagent_t domain are the fol‐
28 lowing:
29 /usr/bin/puppet, /usr/bin/puppetd, /usr/sbin/puppetd, /usr/bin/start-
31 puppet-agent
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 puppetagent policy is very flexible allowing users to setup their pup‐
41 petagent processes in as secure a method as possible.
42 The following process types are defined for puppetagent:
44 puppetagent_t
46 Note: semanage permissive -a puppetagent_t can be used to make the
48 process type puppetagent_t permissive. SELinux does not deny access to
49 permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. pup‐
55 petagent policy is extremely flexible and has several booleans that
56 allow you to manipulate the policy and run puppetagent with the tight‐
57 est access possible.
58 If you want to allow Puppet client to manage all file types, you must
62 turn on the puppetagent_manage_all_files boolean. Disabled by default.
63 setsebool -P puppetagent_manage_all_files 1

205 secure_mode_policyload boolean. Enabled by default.
206 setsebool -P secure_mode_policyload 1
208 If you want to allow unconfined executables to make their heap memory
212 executable. Doing this is a really bad idea. Probably indicates a
213 badly coded executable, but could indicate an attack. This executable
214 should be reported in bugzilla, you must turn on the selin‐
215 uxuser_execheap boolean. Disabled by default.

247 The SELinux process type puppetagent_t can manage files labeled with
248 the following file types. The paths listed are the default paths for
249 these file types. Note the processes UID still need to have DAC per‐
250 missions.
251 file_type
253 all files on the system
255
258 SELinux requires files to have an extended attribute to define the file
259 type.
260 You can see the context of a file using the -Z option to ls
262 Policy governs the access confined processes have to these files.
264 SELinux puppetagent policy is very flexible allowing users to setup
265 their puppetagent processes in as secure a method as possible.
266 The following file types are defined for puppetagent:
268 puppetagent_exec_t
272 - Set files with the puppetagent_exec_t type, if you want to transition
274 an executable to the puppetagent_t domain.
275 Paths:
278 /usr/bin/puppet, /usr/bin/puppetd, /usr/sbin/puppetd,
279 /usr/bin/start-puppet-agent
280 puppetagent_initrc_exec_t
283 - Set files with the puppetagent_initrc_exec_t type, if you want to
285 transition an executable to the puppetagent_initrc_t domain.
286 Note: File context can be temporarily modified with the chcon command.
290 If you want to permanently change the file context you need to use the
291 semanage fcontext command. This will modify the SELinux labeling data‐
292 base. You will need to use restorecon to apply the labels.
293
296 semanage fcontext can also be used to manipulate default file context
297 mappings.
298 semanage permissive can also be used to manipulate whether or not a
300 process type is permissive.
301 semanage module can also be used to enable/disable/install/remove pol‐
303 icy modules.
304 semanage boolean can also be used to manipulate the booleans
306 system-config-selinux is a GUI tool available to customize SELinux pol‐
309 icy settings.
