NAME

6       ypserv_selinux  -  Security  Enhanced  Linux Policy for the ypserv pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  ypserv  processes  via  flexible
11       mandatory access control.
12
13       The  ypserv  processes  execute with the ypserv_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep ypserv_t
20
21
22

ENTRYPOINTS

24       The  ypserv_t  SELinux  type  can be entered via the ypserv_exec_t file
25       type.
26
27       The default entrypoint paths for the ypserv_t domain are the following:
28
29       /usr/sbin/ypserv
30

PROCESS TYPES

32       SELinux defines process types (domains) for each process running on the
33       system
34
35       You can see the context of a process using the -Z option to ps
36
37       Policy  governs  the  access confined processes have to files.  SELinux
38       ypserv policy is very flexible allowing users  to  setup  their  ypserv
39       processes in as secure a method as possible.
40
41       The following process types are defined for ypserv:
42
43       ypserv_t
44
45       Note:  semanage  permissive -a ypserv_t can be used to make the process
46       type ypserv_t permissive. SELinux does not deny  access  to  permissive
47       process  types, but the AVC (SELinux denials) messages are still gener‐
48       ated.

BOOLEANS

52       SELinux policy is customizable based on least access required.   ypserv
53       policy is extremely flexible and has several booleans that allow you to
54       manipulate the policy and run ypserv with the tightest access possible.
55
56
57
58       If you want to dontaudit all  daemons  scheduling  requests  (setsched,
59       sys_nice),  you  must turn on the daemons_dontaudit_scheduling boolean.
60       Enabled by default.
61
62       setsebool -P daemons_dontaudit_scheduling 1
63
64
65
66       If you want to allow all domains to execute in fips_mode, you must turn
67       on the fips_mode boolean. Enabled by default.
68
69       setsebool -P fips_mode 1

MANAGED FILES

74       The  SELinux  process  type  ypserv_t can manage files labeled with the
75       following file types.  The paths listed are the default paths for these
76       file types.  Note the processes UID still need to have DAC permissions.
77

FILE CONTEXTS

127       SELinux requires files to have an extended attribute to define the file
128       type.
129
130       You can see the context of a file using the -Z option to ls
131
132       Policy governs the access  confined  processes  have  to  these  files.
133       SELinux  ypserv  policy  is very flexible allowing users to setup their
134       ypserv processes in as secure a method as possible.
135
136       STANDARD FILE CONTEXT
137
138       SELinux defines the file context types for the ypserv, if you wanted to
139       store  files with these types in a different paths, you need to execute
140       the semanage command to specify alternate labeling  and  then  use  re‐
141       storecon to put the labels on disk.
142
143       semanage fcontext -a -t ypserv_exec_t '/srv/ypserv/content(/.*)?'
144       restorecon -R -v /srv/myypserv_content
145
146       Note:  SELinux  often  uses  regular expressions to specify labels that
147       match multiple files.
148
149       The following file types are defined for ypserv:
150
151
152
153       ypserv_conf_t
154
155       - Set files with the ypserv_conf_t type, if you want to treat the files
156       as ypserv configuration data, usually stored under the /etc directory.
157
158
159
160       ypserv_exec_t
161
162       -  Set  files with the ypserv_exec_t type, if you want to transition an
163       executable to the ypserv_t domain.
164
165
166
167       ypserv_tmp_t
168
169       - Set files with the ypserv_tmp_t type, if you  want  to  store  ypserv
170       temporary files in the /tmp directories.
171
172
173
174       ypserv_var_run_t
175
176       -  Set  files  with the ypserv_var_run_t type, if you want to store the
177       ypserv files under the /run or /var/run directory.
178
179
180
181       Note: File context can be temporarily modified with the chcon  command.
182       If  you want to permanently change the file context you need to use the
183       semanage fcontext command.  This will modify the SELinux labeling data‐
184       base.  You will need to use restorecon to apply the labels.
185
186

COMMANDS

188       semanage  fcontext  can also be used to manipulate default file context
189       mappings.
190
191       semanage permissive can also be used to manipulate  whether  or  not  a
192       process type is permissive.
193
194       semanage  module can also be used to enable/disable/install/remove pol‐
195       icy modules.
196
197       semanage boolean can also be used to manipulate the booleans
198
199
200       system-config-selinux is a GUI tool available to customize SELinux pol‐
201       icy settings.
