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 allow all domains to execute in fips_mode, you must turn
59       on the fips_mode boolean. Enabled by default.
60
61       setsebool -P fips_mode 1

MANAGED FILES

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

FILE CONTEXTS

118       SELinux requires files to have an extended attribute to define the file
119       type.
120
121       You can see the context of a file using the -Z option to ls
122
123       Policy governs the access  confined  processes  have  to  these  files.
124       SELinux  ypserv  policy  is very flexible allowing users to setup their
125       ypserv processes in as secure a method as possible.
126
127       STANDARD FILE CONTEXT
128
129       SELinux defines the file context types for the ypserv, if you wanted to
130       store  files  with  these types in a diffent paths, you need to execute
131       the semanage command  to  sepecify  alternate  labeling  and  then  use
132       restorecon to put the labels on disk.
133
134       semanage fcontext -a -t ypserv_var_run_t '/srv/myypserv_content(/.*)?'
135       restorecon -R -v /srv/myypserv_content
136
137       Note:  SELinux  often  uses  regular expressions to specify labels that
138       match multiple files.
139
140       The following file types are defined for ypserv:
141
142
143
144       ypserv_conf_t
145
146       - Set files with the ypserv_conf_t type, if you want to treat the files
147       as ypserv configuration data, usually stored under the /etc directory.
148
149
150
151       ypserv_exec_t
152
153       -  Set  files with the ypserv_exec_t type, if you want to transition an
154       executable to the ypserv_t domain.
155
156
157
158       ypserv_tmp_t
159
160       - Set files with the ypserv_tmp_t type, if you  want  to  store  ypserv
161       temporary files in the /tmp directories.
162
163
164
165       ypserv_var_run_t
166
167       -  Set  files  with the ypserv_var_run_t type, if you want to store the
168       ypserv files under the /run or /var/run directory.
169
170
171
172       Note: File context can be temporarily modified with the chcon  command.
173       If  you want to permanently change the file context you need to use the
174       semanage fcontext command.  This will modify the SELinux labeling data‐
175       base.  You will need to use restorecon to apply the labels.
176
177

COMMANDS

179       semanage  fcontext  can also be used to manipulate default file context
180       mappings.
181
182       semanage permissive can also be used to manipulate  whether  or  not  a
183       process type is permissive.
184
185       semanage  module can also be used to enable/disable/install/remove pol‐
186       icy modules.
187
188       semanage boolean can also be used to manipulate the booleans
189
190
191       system-config-selinux is a GUI tool available to customize SELinux pol‐
192       icy settings.
