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 al‐
56 low you to manipulate the policy and run puppetagent with the tightest
57 access possible.
58 If you want to dontaudit all daemons scheduling requests (setsched,
62 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
63 Enabled by default.
64 setsebool -P daemons_dontaudit_scheduling 1
66 If you want to deny user domains applications to map a memory region as
70 both executable and writable, this is dangerous and the executable
71 should be reported in bugzilla, you must turn on the deny_execmem bool‐
72 ean. Disabled by default.
73 setsebool -P deny_execmem 1
75 If you want to control the ability to mmap a low area of the address
79 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
80 the mmap_low_allowed boolean. Disabled by default.
81 setsebool -P mmap_low_allowed 1
83 If you want to allow system to run with NIS, you must turn on the
87 nis_enabled boolean. Disabled by default.
88 setsebool -P nis_enabled 1
90 If you want to disable kernel module loading, you must turn on the se‐
94 cure_mode_insmod boolean. Disabled by default.
95 setsebool -P secure_mode_insmod 1
97 If you want to allow unconfined executables to make their heap memory
101 executable. Doing this is a really bad idea. Probably indicates a
102 badly coded executable, but could indicate an attack. This executable
103 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
104 echeap boolean. Disabled by default.
105 setsebool -P selinuxuser_execheap 1
107 If you want to allow unconfined executables to make their stack exe‐
111 cutable. This should never, ever be necessary. Probably indicates a
112 badly coded executable, but could indicate an attack. This executable
113 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
114 stack boolean. Enabled by default.
115 setsebool -P selinuxuser_execstack 1

121 The SELinux process type puppetagent_t can manage files labeled with
122 the following file types. The paths listed are the default paths for
123 these file types. Note the processes UID still need to have DAC per‐
124 missions.
125 file_type
127 all files on the system
129
132 SELinux requires files to have an extended attribute to define the file
133 type.
134 You can see the context of a file using the -Z option to ls
136 Policy governs the access confined processes have to these files.
138 SELinux puppetagent policy is very flexible allowing users to setup
139 their puppetagent processes in as secure a method as possible.
140 STANDARD FILE CONTEXT
142 SELinux defines the file context types for the puppetagent, if you
144 wanted to store files with these types in a different paths, you need
145 to execute the semanage command to specify alternate labeling and then
146 use restorecon to put the labels on disk.
147 semanage fcontext -a -t puppetagent_exec_t '/srv/puppetagent/con‐
149 tent(/.*)?'
150 restorecon -R -v /srv/mypuppetagent_content
151 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154 The following file types are defined for puppetagent:
156 puppetagent_exec_t
160 - Set files with the puppetagent_exec_t type, if you want to transition
162 an executable to the puppetagent_t domain.
163 Paths:
166 /usr/bin/puppet, /usr/bin/puppetd, /usr/sbin/puppetd,
167 /usr/bin/start-puppet-agent
168 puppetagent_initrc_exec_t
171 - Set files with the puppetagent_initrc_exec_t type, if you want to
173 transition an executable to the puppetagent_initrc_t domain.
174 Note: File context can be temporarily modified with the chcon command.
178 If you want to permanently change the file context you need to use the
179 semanage fcontext command. This will modify the SELinux labeling data‐
180 base. You will need to use restorecon to apply the labels.
181
184 semanage fcontext can also be used to manipulate default file context
185 mappings.
186 semanage permissive can also be used to manipulate whether or not a
188 process type is permissive.
189 semanage module can also be used to enable/disable/install/remove pol‐
191 icy modules.
192 semanage boolean can also be used to manipulate the booleans
194 system-config-selinux is a GUI tool available to customize SELinux pol‐
197 icy settings.
