6 ifconfig_selinux - Security Enhanced Linux Policy for the ifconfig pro‐
7 cesses
8
10 Security-Enhanced Linux secures the ifconfig processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep ifconfig_t
20
24 The ifconfig_t SELinux type can be entered via the ifconfig_exec_t file
25 type.
26 The default entrypoint paths for the ifconfig_t domain are the follow‐
28 ing:
29 /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 You can see the context of a process using the -Z option to ps
42 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 The following process types are defined for ifconfig:
48 ifconfig_t
50 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
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 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 setsebool -P authlogin_nsswitch_use_ldap 1
70 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 setsebool -P fips_mode 1
77 If you want to allow confined applications to run with kerberos, you
81 must turn on the kerberos_enabled boolean. Disabled by default.
82 setsebool -P kerberos_enabled 1
84 If you want to allow system to run with NIS, you must turn on the
88 nis_enabled boolean. Disabled by default.
89 setsebool -P nis_enabled 1
91 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 setsebool -P nscd_use_shm 1
98
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 ifconfig_var_run_t
107 /var/run/netns(/.*)?
109 ipsec_var_run_t
111 /var/racoon(/.*)?
113 /var/run/pluto(/.*)?
114 /var/run/charon.*
115 /var/run/racoon.pid
116 /var/run/charon.ctl
117 /var/run/charon.dck
118 /var/run/charon.vici
119 tlp_var_run_t
121 /var/run/tlp(/.*)?
123 vmware_log_t
125 /var/log/vmware.*
127 /var/log/vnetlib.*
128
131 SELinux requires files to have an extended attribute to define the file
132 type.
133 You can see the context of a file using the -Z option to ls
135 Policy governs the access confined processes have to these files.
137 SELinux ifconfig policy is very flexible allowing users to setup their
138 ifconfig processes in as secure a method as possible.
139 STANDARD FILE CONTEXT
141 SELinux defines the file context types for the ifconfig, if you wanted
143 to store files with these types in a diffent paths, you need to execute
144 the semanage command to sepecify alternate labeling and then use
145 restorecon to put the labels on disk.
146 semanage fcontext -a -t ifconfig_var_run_t '/srv/myifconfig_con‐
148 tent(/.*)?'
149 restorecon -R -v /srv/myifconfig_content
150 Note: SELinux often uses regular expressions to specify labels that
152 match multiple files.
153 The following file types are defined for ifconfig:
155 ifconfig_exec_t
159 - Set files with the ifconfig_exec_t type, if you want to transition an
161 executable to the ifconfig_t domain.
162 Paths:
165 /bin/ip, /sbin/ip, /sbin/iw, /sbin/tc, /usr/bin/ip, /usr/sbin/ip,
166 /usr/sbin/iw, /usr/sbin/tc, /sbin/ethtool, /sbin/ifconfig,
167 /sbin/iwconfig, /sbin/mii-tool, /usr/sbin/ethtool,
168 /usr/sbin/ifconfig, /usr/sbin/iwconfig, /usr/sbin/mii-tool,
169 /sbin/ipx_configure, /sbin/ipx_interface, /sbin/ipx_internal_net,
170 /usr/sbin/ipx_configure, /usr/sbin/ipx_interface,
171 /usr/sbin/ipx_internal_net
172 ifconfig_var_run_t
175 - Set files with the ifconfig_var_run_t type, if you want to store the
177 ifconfig files under the /run or /var/run directory.
178 Note: File context can be temporarily modified with the chcon command.
182 If you want to permanently change the file context you need to use the
183 semanage fcontext command. This will modify the SELinux labeling data‐
184 base. You will need to use restorecon to apply the labels.
185
188 semanage fcontext can also be used to manipulate default file context
189 mappings.
190 semanage permissive can also be used to manipulate whether or not a
192 process type is permissive.
193 semanage module can also be used to enable/disable/install/remove pol‐
195 icy modules.
196 semanage boolean can also be used to manipulate the booleans
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
201 icy settings.
