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 allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
64 The SELinux process type ypxfr_t can manage files labeled with the fol‐
65 lowing file types. The paths listed are the default paths for these
66 file types. Note the processes UID still need to have DAC permissions.

114 SELinux requires files to have an extended attribute to define the file
115 type.
116
117 You can see the context of a file using the -Z option to ls
118
119 Policy governs the access confined processes have to these files.
120 SELinux ypxfr policy is very flexible allowing users to setup their
121 ypxfr processes in as secure a method as possible.
122
123 STANDARD FILE CONTEXT
124
125 SELinux defines the file context types for the ypxfr, if you wanted to
126 store files with these types in a diffent paths, you need to execute
127 the semanage command to sepecify alternate labeling and then use re‐
128 storecon to put the labels on disk.
129
130 semanage fcontext -a -t ypxfr_var_run_t '/srv/myypxfr_content(/.*)?'
131 restorecon -R -v /srv/myypxfr_content
132
133 Note: SELinux often uses regular expressions to specify labels that
134 match multiple files.
135
136 The following file types are defined for ypxfr:
137
138
139
140 ypxfr_exec_t
141
142 - Set files with the ypxfr_exec_t type, if you want to transition an
143 executable to the ypxfr_t domain.
144
145
146 Paths:
147 /usr/lib/yp/ypxfr, /usr/sbin/rpc.ypxfrd
148
149
150 ypxfr_var_run_t
151
152 - Set files with the ypxfr_var_run_t type, if you want to store the
153 ypxfr files under the /run or /var/run directory.
154
155
156
157 Note: File context can be temporarily modified with the chcon command.
158 If you want to permanently change the file context you need to use the
159 semanage fcontext command. This will modify the SELinux labeling data‐
160 base. You will need to use restorecon to apply the labels.
161
162
164 semanage fcontext can also be used to manipulate default file context
165 mappings.
166
167 semanage permissive can also be used to manipulate whether or not a
168 process type is permissive.
169
170 semanage module can also be used to enable/disable/install/remove pol‐
171 icy modules.
172
173 semanage boolean can also be used to manipulate the booleans
174
175
176 system-config-selinux is a GUI tool available to customize SELinux pol‐
177 icy settings.
