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/sbin/puppetmasterd
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 puppetmaster policy is very flexible allowing users to setup their pup‐
40 petmaster processes in as secure a method as possible.
41 The following process types are defined for puppetmaster:
43 puppetmaster_t
45 Note: semanage permissive -a puppetmaster_t can be used to make the
47 process type puppetmaster_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. puppet‐
54 master policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run puppetmaster with the tightest
56 access possible.
57 If you want to allow Puppet master to use connect to mysql and post‐
61 gresql database, you must turn on the puppetmaster_use_db boolean. Dis‐
62 abled by default.
63 setsebool -P puppetmaster_use_db 1
65 If you want to allow all daemons to write corefiles to /, you must turn
69 on the allow_daemons_dump_core boolean. Disabled by default.
70 setsebool -P allow_daemons_dump_core 1
72 If you want to allow all daemons to use tcp wrappers, you must turn on
76 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
77 setsebool -P allow_daemons_use_tcp_wrapper 1
79 If you want to allow all daemons the ability to read/write terminals,
83 you must turn on the allow_daemons_use_tty boolean. Disabled by
84 default.
85 setsebool -P allow_daemons_use_tty 1
87 If you want to allow all domains to use other domains file descriptors,
91 you must turn on the allow_domain_fd_use boolean. Enabled by default.
92 setsebool -P allow_domain_fd_use 1
94 If you want to allow confined applications to run with kerberos, you
98 must turn on the allow_kerberos boolean. Enabled by default.
99 setsebool -P allow_kerberos 1
101 If you want to allow sysadm to debug or ptrace all processes, you must
105 turn on the allow_ptrace boolean. Disabled by default.
106 setsebool -P allow_ptrace 1
108 If you want to allow system to run with NIS, you must turn on the
112 allow_ypbind boolean. Disabled by default.
113 setsebool -P allow_ypbind 1
115 If you want to enable cluster mode for daemons, you must turn on the
119 daemons_enable_cluster_mode boolean. Disabled by default.
120 setsebool -P daemons_enable_cluster_mode 1
122 If you want to allow all domains to have the kernel load modules, you
126 must turn on the domain_kernel_load_modules boolean. Disabled by
127 default.
128 setsebool -P domain_kernel_load_modules 1
130 If you want to allow all domains to execute in fips_mode, you must turn
134 on the fips_mode boolean. Enabled by default.
135 setsebool -P fips_mode 1
137 If you want to enable reading of urandom for all domains, you must turn
141 on the global_ssp boolean. Disabled by default.
142 setsebool -P global_ssp 1
144 If you want to enable support for upstart as the init program, you must
148 turn on the init_upstart boolean. Enabled by default.
149 setsebool -P init_upstart 1
151 If you want to allow confined applications to use nscd shared memory,
155 you must turn on the nscd_use_shm boolean. Enabled by default.
156 setsebool -P nscd_use_shm 1
158
162 The SELinux process type puppetmaster_t can manage files labeled with
163 the following file types. The paths listed are the default paths for
164 these file types. Note the processes UID still need to have DAC per‐
165 missions.

244 SELinux requires files to have an extended attribute to define the file
245 type.
246 You can see the context of a file using the -Z option to ls
248 Policy governs the access confined processes have to these files.
250 SELinux puppetmaster policy is very flexible allowing users to setup
251 their puppetmaster processes in as secure a method as possible.
252 STANDARD FILE CONTEXT
254 SELinux defines the file context types for the puppetmaster, if you
256 wanted to store files with these types in a diffent paths, you need to
257 execute the semanage command to sepecify alternate labeling and then
258 use restorecon to put the labels on disk.
259 semanage fcontext -a -t puppetmaster_tmp_t '/srv/mypuppetmaster_con‐
261 tent(/.*)?'
262 restorecon -R -v /srv/mypuppetmaster_content
263 Note: SELinux often uses regular expressions to specify labels that
265 match multiple files.
266 The following file types are defined for puppetmaster:
268 puppetmaster_exec_t
272 - Set files with the puppetmaster_exec_t type, if you want to transi‐
274 tion an executable to the puppetmaster_t domain.
275 puppetmaster_initrc_exec_t
279 - Set files with the puppetmaster_initrc_exec_t type, if you want to
281 transition an executable to the puppetmaster_initrc_t domain.
282 puppetmaster_tmp_t
286 - Set files with the puppetmaster_tmp_t type, if you want to store pup‐
288 petmaster temporary files in the /tmp directories.
289 Note: File context can be temporarily modified with the chcon command.
293 If you want to permanently change the file context you need to use the
294 semanage fcontext command. This will modify the SELinux labeling data‐
295 base. You will need to use restorecon to apply the labels.
296
299 semanage fcontext can also be used to manipulate default file context
300 mappings.
301 semanage permissive can also be used to manipulate whether or not a
303 process type is permissive.
304 semanage module can also be used to enable/disable/install/remove pol‐
306 icy modules.
307 semanage boolean can also be used to manipulate the booleans
309 system-config-selinux is a GUI tool available to customize SELinux pol‐
312 icy settings.
