7 cesses

10 Security-Enhanced Linux secures the ifconfig processes via flexible
11 mandatory access control.
12
13 The ifconfig processes execute with the ifconfig_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep ifconfig_t
20
21
22
24 The ifconfig_t SELinux type can be entered via the ifconfig_exec_t file
25 type.
26
27 The default entrypoint paths for the ifconfig_t domain are the follow‐
28 ing:
29
30 /bin/ip, /sbin/ip, /sbin/iw, /sbin/tc, /usr/bin/ip, /usr/sbin/ip,
31 /usr/sbin/iw, /usr/sbin/tc, /sbin/ethtool, /sbin/ifconfig, /sbin/iwcon‐
32 fig, /sbin/mii-tool, /usr/sbin/ethtool, /usr/sbin/ifconfig,
33 /usr/sbin/iwconfig, /usr/sbin/mii-tool, /sbin/ipx_configure,
34 /sbin/ipx_interface, /sbin/ipx_internal_net, /usr/sbin/ipx_configure,
35 /usr/sbin/ipx_interface, /usr/sbin/ipx_internal_net

38 SELinux defines process types (domains) for each process running on the
39 system
40
41 You can see the context of a process using the -Z option to ps
42
43 Policy governs the access confined processes have to files. SELinux
44 ifconfig policy is very flexible allowing users to setup their ifconfig
45 processes in as secure a method as possible.
46
47 The following process types are defined for ifconfig:
48
49 ifconfig_t
50
51 Note: semanage permissive -a ifconfig_t can be used to make the process
52 type ifconfig_t permissive. SELinux does not deny access to permissive
53 process types, but the AVC (SELinux denials) messages are still gener‐
54 ated.
55
56
58 SELinux policy is customizable based on least access required. ifcon‐
59 fig policy is extremely flexible and has several booleans that allow
60 you to manipulate the policy and run ifconfig with the tightest access
61 possible.
62
63
64
65 If you want to allow users to resolve user passwd entries directly from
66 ldap rather then using a sssd server, you must turn on the authlo‐
67 gin_nsswitch_use_ldap boolean. Disabled by default.
68
69 setsebool -P authlogin_nsswitch_use_ldap 1
70
71
72
73 If you want to allow all domains to execute in fips_mode, you must turn
74 on the fips_mode boolean. Enabled by default.
75
76 setsebool -P fips_mode 1
77
78
79
80 If you want to allow confined applications to run with kerberos, you
81 must turn on the kerberos_enabled boolean. Enabled by default.
82
83 setsebool -P kerberos_enabled 1
84
85
86
87 If you want to allow system to run with NIS, you must turn on the
88 nis_enabled boolean. Disabled by default.
89
90 setsebool -P nis_enabled 1
91
92
93
94 If you want to allow confined applications to use nscd shared memory,
95 you must turn on the nscd_use_shm boolean. Disabled by default.
96
97 setsebool -P nscd_use_shm 1
98
99

102 The SELinux process type ifconfig_t can manage files labeled with the
103 following file types. The paths listed are the default paths for these
104 file types. Note the processes UID still need to have DAC permissions.
105
106 ifconfig_var_run_t
107
108 /var/run/netns(/.*)?
109
110 ipsec_var_run_t
111
112 /var/racoon(/.*)?
113 /var/run/pluto(/.*)?
114 /var/run/charon.*
115 /var/run/racoon.pid
116 /var/run/charon.ctl
117 /var/run/charon.vici
118
119 tlp_var_run_t
120
121 /var/run/tlp(/.*)?
122
123
125 SELinux requires files to have an extended attribute to define the file
126 type.
127
128 You can see the context of a file using the -Z option to ls
129
130 Policy governs the access confined processes have to these files.
131 SELinux ifconfig policy is very flexible allowing users to setup their
132 ifconfig processes in as secure a method as possible.
133
134 STANDARD FILE CONTEXT
135
136 SELinux defines the file context types for the ifconfig, if you wanted
137 to store files with these types in a diffent paths, you need to execute
138 the semanage command to sepecify alternate labeling and then use
139 restorecon to put the labels on disk.
140
141 semanage fcontext -a -t ifconfig_var_run_t '/srv/myifconfig_con‐
142 tent(/.*)?'
143 restorecon -R -v /srv/myifconfig_content
144
145 Note: SELinux often uses regular expressions to specify labels that
146 match multiple files.
147
148 The following file types are defined for ifconfig:
149
150
151
152 ifconfig_exec_t
153
154 - Set files with the ifconfig_exec_t type, if you want to transition an
155 executable to the ifconfig_t domain.
156
157
158 Paths:
159 /bin/ip, /sbin/ip, /sbin/iw, /sbin/tc, /usr/bin/ip, /usr/sbin/ip,
160 /usr/sbin/iw, /usr/sbin/tc, /sbin/ethtool, /sbin/ifconfig,
161 /sbin/iwconfig, /sbin/mii-tool, /usr/sbin/ethtool,
162 /usr/sbin/ifconfig, /usr/sbin/iwconfig, /usr/sbin/mii-tool,
163 /sbin/ipx_configure, /sbin/ipx_interface, /sbin/ipx_internal_net,
164 /usr/sbin/ipx_configure, /usr/sbin/ipx_interface,
165 /usr/sbin/ipx_internal_net
166
167
168 ifconfig_var_run_t
169
170 - Set files with the ifconfig_var_run_t type, if you want to store the
171 ifconfig files under the /run or /var/run directory.
172
173
174
175 Note: File context can be temporarily modified with the chcon command.
176 If you want to permanently change the file context you need to use the
177 semanage fcontext command. This will modify the SELinux labeling data‐
178 base. You will need to use restorecon to apply the labels.
179
180
182 semanage fcontext can also be used to manipulate default file context
183 mappings.
184
185 semanage permissive can also be used to manipulate whether or not a
186 process type is permissive.
187
188 semanage module can also be used to enable/disable/install/remove pol‐
189 icy modules.
190
191 semanage boolean can also be used to manipulate the booleans
192
193
194 system-config-selinux is a GUI tool available to customize SELinux pol‐
195 icy settings.
