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, /usr/sbin/rpc.yppasswdd.env
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.
57 If you want to dontaudit all daemons scheduling requests (setsched,
61 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
62 Enabled by default.
63 setsebool -P daemons_dontaudit_scheduling 1
65 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70 setsebool -P fips_mode 1
72 If you want to allow system to run with NIS, you must turn on the
76 nis_enabled boolean. Disabled by default.
77 setsebool -P nis_enabled 1

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

154 SELinux requires files to have an extended attribute to define the file
155 type.
156 You can see the context of a file using the -Z option to ls
158 Policy governs the access confined processes have to these files.
160 SELinux yppasswdd policy is very flexible allowing users to setup their
161 yppasswdd processes in as secure a method as possible.
162 STANDARD FILE CONTEXT
164 SELinux defines the file context types for the yppasswdd, if you wanted
166 to store files with these types in a different paths, you need to exe‐
167 cute the semanage command to specify alternate labeling and then use
168 restorecon to put the labels on disk.
169 semanage fcontext -a -t yppasswdd_exec_t '/srv/yppasswdd/content(/.*)?'
171 restorecon -R -v /srv/myyppasswdd_content
172 Note: SELinux often uses regular expressions to specify labels that
174 match multiple files.
175 The following file types are defined for yppasswdd:
177 yppasswdd_exec_t
181 - Set files with the yppasswdd_exec_t type, if you want to transition
183 an executable to the yppasswdd_t domain.
184 Paths:
187 /usr/sbin/rpc.yppasswdd, /usr/sbin/rpc.yppasswdd.env
188 yppasswdd_var_run_t
191 - Set files with the yppasswdd_var_run_t type, if you want to store the
193 yppasswdd files under the /run or /var/run directory.
194 Note: File context can be temporarily modified with the chcon command.
198 If you want to permanently change the file context you need to use the
199 semanage fcontext command. This will modify the SELinux labeling data‐
200 base. You will need to use restorecon to apply the labels.
201
204 semanage fcontext can also be used to manipulate default file context
205 mappings.
206 semanage permissive can also be used to manipulate whether or not a
208 process type is permissive.
209 semanage module can also be used to enable/disable/install/remove pol‐
211 icy modules.
212 semanage boolean can also be used to manipulate the booleans
214 system-config-selinux is a GUI tool available to customize SELinux pol‐
217 icy settings.
