6 ypxfr_selinux - Security Enhanced Linux Policy for the ypxfr processes
7
9 Security-Enhanced Linux secures the ypxfr processes via flexible manda‐
10 tory access control.
11
12 The ypxfr processes execute with the ypxfr_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep ypxfr_t
19
20
21
23 The ypxfr_t SELinux type can be entered via the ypxfr_exec_t file type.
24
25 The default entrypoint paths for the ypxfr_t domain are the following:
26
27 /usr/lib/yp/ypxfr, /usr/sbin/rpc.ypxfrd
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 ypxfr policy is very flexible allowing users to setup their ypxfr pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for ypxfr:
40
41 ypxfr_t
42
43 Note: semanage permissive -a ypxfr_t can be used to make the process
44 type ypxfr_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. ypxfr
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run ypxfr with the tightest access possible.
53
54
55
56 If you want to dontaudit all daemons scheduling requests (setsched,
57 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
58 Enabled by default.
59
60 setsebool -P daemons_dontaudit_scheduling 1
61
62
63
64 If you want to allow all domains to execute in fips_mode, you must turn
65 on the fips_mode boolean. Enabled by default.
66
67 setsebool -P fips_mode 1
68
69
70
72 The SELinux process type ypxfr_t can manage files labeled with the fol‐
73 lowing file types. The paths listed are the default paths for these
74 file types. Note the processes UID still need to have DAC permissions.

122 SELinux requires files to have an extended attribute to define the file
123 type.
124
125 You can see the context of a file using the -Z option to ls
126
127 Policy governs the access confined processes have to these files.
128 SELinux ypxfr policy is very flexible allowing users to setup their
129 ypxfr processes in as secure a method as possible.
130
131 STANDARD FILE CONTEXT
132
133 SELinux defines the file context types for the ypxfr, if you wanted to
134 store files with these types in a different paths, you need to execute
135 the semanage command to specify alternate labeling and then use re‐
136 storecon to put the labels on disk.
137
138 semanage fcontext -a -t ypxfr_exec_t '/srv/ypxfr/content(/.*)?'
139 restorecon -R -v /srv/myypxfr_content
140
141 Note: SELinux often uses regular expressions to specify labels that
142 match multiple files.
143
144 The following file types are defined for ypxfr:
145
146
147
148 ypxfr_exec_t
149
150 - Set files with the ypxfr_exec_t type, if you want to transition an
151 executable to the ypxfr_t domain.
152
153
154 Paths:
155 /usr/lib/yp/ypxfr, /usr/sbin/rpc.ypxfrd
156
157
158 ypxfr_var_run_t
159
160 - Set files with the ypxfr_var_run_t type, if you want to store the
161 ypxfr files under the /run or /var/run directory.
162
163
164
165 Note: File context can be temporarily modified with the chcon command.
166 If you want to permanently change the file context you need to use the
167 semanage fcontext command. This will modify the SELinux labeling data‐
168 base. You will need to use restorecon to apply the labels.
169
170
172 semanage fcontext can also be used to manipulate default file context
173 mappings.
174
175 semanage permissive can also be used to manipulate whether or not a
176 process type is permissive.
177
178 semanage module can also be used to enable/disable/install/remove pol‐
179 icy modules.
180
181 semanage boolean can also be used to manipulate the booleans
182
183
184 system-config-selinux is a GUI tool available to customize SELinux pol‐
185 icy settings.
