6 yppasswdd_selinux - Security Enhanced Linux Policy for the yppasswdd
7 processes
8
10 Security-Enhanced Linux secures the yppasswdd processes via flexible
11 mandatory access control.
12 The yppasswdd processes execute with the yppasswdd_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 yppasswdd_t
20
24 The yppasswdd_t SELinux type can be entered via the yppasswdd_exec_t
25 file type.
26 The default entrypoint paths for the yppasswdd_t domain are the follow‐
28 ing:
29 /usr/sbin/rpc.yppasswdd
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 yppasswdd policy is very flexible allowing users to setup their yppass‐
40 wdd processes in as secure a method as possible.
41 The following process types are defined for yppasswdd:
43 yppasswdd_t
45 Note: semanage permissive -a yppasswdd_t can be used to make the
47 process type yppasswdd_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. yppass‐
54 wdd policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run yppasswdd with the tightest access
56 possible.

111 must turn on the domain_kernel_load_modules boolean. Disabled by
112 default.
113 setsebool -P domain_kernel_load_modules 1
115 If you want to allow all domains to execute in fips_mode, you must turn
119 on the fips_mode boolean. Enabled by default.
120 setsebool -P fips_mode 1
122 If you want to enable reading of urandom for all domains, you must turn
126 on the global_ssp boolean. Disabled by default.
127 setsebool -P global_ssp 1
129 If you want to enable support for upstart as the init program, you must
133 turn on the init_upstart boolean. Enabled by default.
134 setsebool -P init_upstart 1

140 The SELinux process type yppasswdd_t can manage files labeled with the
141 following file types. The paths listed are the default paths for these
142 file types. Note the processes UID still need to have DAC permissions.

221 SELinux requires files to have an extended attribute to define the file
222 type.
223 You can see the context of a file using the -Z option to ls
225 Policy governs the access confined processes have to these files.
227 SELinux yppasswdd policy is very flexible allowing users to setup their
228 yppasswdd processes in as secure a method as possible.
229 STANDARD FILE CONTEXT
231 SELinux defines the file context types for the yppasswdd, if you wanted
233 to store files with these types in a diffent paths, you need to execute
234 the semanage command to sepecify alternate labeling and then use
235 restorecon to put the labels on disk.
236 semanage fcontext -a -t yppasswdd_var_run_t '/srv/myyppasswdd_con‐
238 tent(/.*)?'
239 restorecon -R -v /srv/myyppasswdd_content
240 Note: SELinux often uses regular expressions to specify labels that
242 match multiple files.
243 The following file types are defined for yppasswdd:
245 yppasswdd_exec_t
249 - Set files with the yppasswdd_exec_t type, if you want to transition
251 an executable to the yppasswdd_t domain.
252 yppasswdd_var_run_t
256 - Set files with the yppasswdd_var_run_t type, if you want to store the
258 yppasswdd files under the /run or /var/run directory.
259 Note: File context can be temporarily modified with the chcon command.
263 If you want to permanently change the file context you need to use the
264 semanage fcontext command. This will modify the SELinux labeling data‐
265 base. You will need to use restorecon to apply the labels.
266
269 semanage fcontext can also be used to manipulate default file context
270 mappings.
271 semanage permissive can also be used to manipulate whether or not a
273 process type is permissive.
274 semanage module can also be used to enable/disable/install/remove pol‐
276 icy modules.
277 semanage boolean can also be used to manipulate the booleans
279 system-config-selinux is a GUI tool available to customize SELinux pol‐
282 icy settings.
