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

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

115       SELinux requires files to have an extended attribute to define the file
116       type.
117
118       You can see the context of a file using the -Z option to ls
119
120       Policy governs the access  confined  processes  have  to  these  files.
121       SELinux  ypserv  policy  is very flexible allowing users to setup their
122       ypserv processes in as secure a method as possible.
123
124       STANDARD FILE CONTEXT
125
126       SELinux defines the file context types for the ypserv, if you wanted to
127       store  files  with  these types in a diffent paths, you need to execute
128       the semanage command  to  sepecify  alternate  labeling  and  then  use
129       restorecon to put the labels on disk.
130
131       semanage fcontext -a -t ypserv_var_run_t '/srv/myypserv_content(/.*)?'
132       restorecon -R -v /srv/myypserv_content
133
134       Note:  SELinux  often  uses  regular expressions to specify labels that
135       match multiple files.
136
137       The following file types are defined for ypserv:
138
139
140
141       ypserv_conf_t
142
143       - Set files with the ypserv_conf_t type, if you want to treat the files
144       as ypserv configuration data, usually stored under the /etc directory.
145
146
147
148       ypserv_exec_t
149
150       -  Set  files with the ypserv_exec_t type, if you want to transition an
151       executable to the ypserv_t domain.
152
153
154
155       ypserv_tmp_t
156
157       - Set files with the ypserv_tmp_t type, if you  want  to  store  ypserv
158       temporary files in the /tmp directories.
159
160
161
162       ypserv_var_run_t
163
164       -  Set  files  with the ypserv_var_run_t type, if you want to store the
165       ypserv files under the /run or /var/run directory.
166
167
168
169       Note: File context can be temporarily modified with the chcon  command.
170       If  you want to permanently change the file context you need to use the
171       semanage fcontext command.  This will modify the SELinux labeling data‐
172       base.  You will need to use restorecon to apply the labels.
173
174

COMMANDS

176       semanage  fcontext  can also be used to manipulate default file context
177       mappings.
178
179       semanage permissive can also be used to manipulate  whether  or  not  a
180       process type is permissive.
181
182       semanage  module can also be used to enable/disable/install/remove pol‐
183       icy modules.
184
185       semanage boolean can also be used to manipulate the booleans
186
187
188       system-config-selinux is a GUI tool available to customize SELinux pol‐
189       icy settings.
