6 puppetmaster_selinux - Security Enhanced Linux Policy for the puppet‐
7 master processes
8
10 Security-Enhanced Linux secures the puppetmaster processes via flexible
11 mandatory access control.
12 The puppetmaster processes execute with the puppetmaster_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep puppetmaster_t
20
24 The puppetmaster_t SELinux type can be entered via the puppetmas‐
25 ter_exec_t file type.
26 The default entrypoint paths for the puppetmaster_t domain are the fol‐
28 lowing:
29 /usr/bin/puppetmasterd, /usr/sbin/puppetmasterd, /usr/bin/start-puppet-
31 master
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 puppetmaster policy is very flexible allowing users to setup their pup‐
41 petmaster processes in as secure a method as possible.
42 The following process types are defined for puppetmaster:
44 puppetmaster_t
46 Note: semanage permissive -a puppetmaster_t can be used to make the
48 process type puppetmaster_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. puppet‐
55 master policy is extremely flexible and has several booleans that allow
56 you to manipulate the policy and run puppetmaster with the tightest
57 access possible.
58 If you want to allow Puppet master to use connect to MySQL and Post‐
62 greSQL database, you must turn on the puppetmaster_use_db boolean. Dis‐
63 abled by default.
64 setsebool -P puppetmaster_use_db 1
66 If you want to allow users to resolve user passwd entries directly from
70 ldap rather then using a sssd server, you must turn on the authlo‐
71 gin_nsswitch_use_ldap boolean. Disabled by default.
72 setsebool -P authlogin_nsswitch_use_ldap 1

99 you must turn on the daemons_use_tty boolean. Disabled by default.
100 setsebool -P daemons_use_tty 1
102 If you want to deny any process from ptracing or debugging any other
106 processes, you must turn on the deny_ptrace boolean. Enabled by
107 default.
108 setsebool -P deny_ptrace 1
110 If you want to allow any process to mmap any file on system with
114 attribute file_type, you must turn on the domain_can_mmap_files bool‐
115 ean. Enabled by default.
116 setsebool -P domain_can_mmap_files 1
118 If you want to allow all domains write to kmsg_device, while kernel is
122 executed with systemd.log_target=kmsg parameter, you must turn on the
123 domain_can_write_kmsg boolean. Disabled by default.
124 setsebool -P domain_can_write_kmsg 1
126 If you want to allow all domains to use other domains file descriptors,
130 you must turn on the domain_fd_use boolean. Enabled by default.
131 setsebool -P domain_fd_use 1
133 If you want to allow all domains to have the kernel load modules, you
137 must turn on the domain_kernel_load_modules boolean. Disabled by
138 default.
139 setsebool -P domain_kernel_load_modules 1
141 If you want to allow all domains to execute in fips_mode, you must turn
145 on the fips_mode boolean. Enabled by default.
146 setsebool -P fips_mode 1
148 If you want to enable reading of urandom for all domains, you must turn
152 on the global_ssp boolean. Disabled by default.
153 setsebool -P global_ssp 1
155 If you want to allow confined applications to run with kerberos, you
159 must turn on the kerberos_enabled boolean. Enabled by default.
160 setsebool -P kerberos_enabled 1
162 If you want to allow system to run with NIS, you must turn on the
166 nis_enabled boolean. Disabled by default.
167 setsebool -P nis_enabled 1
169 If you want to allow confined applications to use nscd shared memory,
173 you must turn on the nscd_use_shm boolean. Disabled by default.
174 setsebool -P nscd_use_shm 1
176
180 The SELinux process type puppetmaster_t can manage files labeled with
181 the following file types. The paths listed are the default paths for
182 these file types. Note the processes UID still need to have DAC per‐
183 missions.

241 SELinux requires files to have an extended attribute to define the file
242 type.
243 You can see the context of a file using the -Z option to ls
245 Policy governs the access confined processes have to these files.
247 SELinux puppetmaster policy is very flexible allowing users to setup
248 their puppetmaster processes in as secure a method as possible.
249 STANDARD FILE CONTEXT
251 SELinux defines the file context types for the puppetmaster, if you
253 wanted to store files with these types in a diffent paths, you need to
254 execute the semanage command to sepecify alternate labeling and then
255 use restorecon to put the labels on disk.
256 semanage fcontext -a -t puppetmaster_tmp_t '/srv/mypuppetmaster_con‐
258 tent(/.*)?'
259 restorecon -R -v /srv/mypuppetmaster_content
260 Note: SELinux often uses regular expressions to specify labels that
262 match multiple files.
263 The following file types are defined for puppetmaster:
265 puppetmaster_exec_t
269 - Set files with the puppetmaster_exec_t type, if you want to transi‐
271 tion an executable to the puppetmaster_t domain.
272 Paths:
275 /usr/bin/puppetmasterd, /usr/sbin/puppetmasterd, /usr/bin/start-
276 puppet-master
277 puppetmaster_initrc_exec_t
280 - Set files with the puppetmaster_initrc_exec_t type, if you want to
282 transition an executable to the puppetmaster_initrc_t domain.
283 puppetmaster_tmp_t
287 - Set files with the puppetmaster_tmp_t type, if you want to store pup‐
289 petmaster temporary files in the /tmp directories.
290 Note: File context can be temporarily modified with the chcon command.
294 If you want to permanently change the file context you need to use the
295 semanage fcontext command. This will modify the SELinux labeling data‐
296 base. You will need to use restorecon to apply the labels.
297
300 semanage fcontext can also be used to manipulate default file context
301 mappings.
302 semanage permissive can also be used to manipulate whether or not a
304 process type is permissive.
305 semanage module can also be used to enable/disable/install/remove pol‐
307 icy modules.
308 semanage boolean can also be used to manipulate the booleans
310 system-config-selinux is a GUI tool available to customize SELinux pol‐
313 icy settings.
