6 firewallgui_selinux - Security Enhanced Linux Policy for the firewall‐
7 gui processes
8
10 Security-Enhanced Linux secures the firewallgui processes via flexible
11 mandatory access control.
12
13 The firewallgui processes execute with the firewallgui_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep firewallgui_t
20
21
22
24 The firewallgui_t SELinux type can be entered via the firewall‐
25 gui_exec_t file type.
26
27 The default entrypoint paths for the firewallgui_t domain are the fol‐
28 lowing:
29
30 /usr/share/system-config-firewall/system-config-firewall-mechanism.py
31
33 SELinux defines process types (domains) for each process running on the
34 system
35
36 You can see the context of a process using the -Z option to ps
37
38 Policy governs the access confined processes have to files. SELinux
39 firewallgui policy is very flexible allowing users to setup their fire‐
40 wallgui processes in as secure a method as possible.
41
42 The following process types are defined for firewallgui:
43
44 firewallgui_t
45
46 Note: semanage permissive -a firewallgui_t can be used to make the
47 process type firewallgui_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. fire‐
54 wallgui policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run firewallgui with the tight‐
56 est access possible.
57
58
59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.

100 you must turn on the domain_fd_use boolean. Enabled by default.
101
102 setsebool -P domain_fd_use 1
103
104
105
106 If you want to allow all domains to have the kernel load modules, you
107 must turn on the domain_kernel_load_modules boolean. Disabled by
108 default.
109
110 setsebool -P domain_kernel_load_modules 1
111
112
113
114 If you want to allow all domains to execute in fips_mode, you must turn
115 on the fips_mode boolean. Enabled by default.
116

118
119
120
121 If you want to enable reading of urandom for all domains, you must turn
122 on the global_ssp boolean. Disabled by default.
123
124 setsebool -P global_ssp 1
125
126
127
128 If you want to allow confined applications to run with kerberos, you
129 must turn on the kerberos_enabled boolean. Enabled by default.
130
131 setsebool -P kerberos_enabled 1
132
133
134
135 If you want to allow system to run with NIS, you must turn on the
136 nis_enabled boolean. Disabled by default.
137
138 setsebool -P nis_enabled 1
139
140
141
142 If you want to allow confined applications to use nscd shared memory,
143 you must turn on the nscd_use_shm boolean. Disabled by default.
144
145 setsebool -P nscd_use_shm 1
146
147
148
150 The SELinux process type firewallgui_t can manage files labeled with
151 the following file types. The paths listed are the default paths for
152 these file types. Note the processes UID still need to have DAC per‐
153 missions.
154
155 firewallgui_tmp_t
156
157
158 system_conf_t
159
160 /ostree/repo(/.*)?
161 /etc/yum.repos.d(/.*)?
162 /etc/sysctl.conf(.old)?
163 /etc/sysconfig/ip6?tables.*
164 /etc/ostree/remotes.d(/.*)?
165 /etc/sysconfig/ipvsadm.*
166 /etc/sysconfig/ebtables.*
167 /etc/sysconfig/system-config-firewall.*
168 /ostree/deploy/rhel-atomic-host/deploy(/.*)?
169
170 systemd_passwd_var_run_t

172 /var/run/systemd/ask-password(/.*)?
173 /var/run/systemd/ask-password-block(/.*)?

175
177 SELinux requires files to have an extended attribute to define the file
178 type.
179
180 You can see the context of a file using the -Z option to ls
181
182 Policy governs the access confined processes have to these files.
183 SELinux firewallgui policy is very flexible allowing users to setup
184 their firewallgui processes in as secure a method as possible.
185
186 STANDARD FILE CONTEXT
187
188 SELinux defines the file context types for the firewallgui, if you
189 wanted to store files with these types in a diffent paths, you need to
190 execute the semanage command to sepecify alternate labeling and then
191 use restorecon to put the labels on disk.
192
193 semanage fcontext -a -t firewallgui_tmp_t '/srv/myfirewallgui_con‐
194 tent(/.*)?'
195 restorecon -R -v /srv/myfirewallgui_content
196
197 Note: SELinux often uses regular expressions to specify labels that
198 match multiple files.
199
200 The following file types are defined for firewallgui:
201
202
203
204 firewallgui_exec_t
205
206 - Set files with the firewallgui_exec_t type, if you want to transition
207 an executable to the firewallgui_t domain.
208
209
210
211 firewallgui_tmp_t
212
213 - Set files with the firewallgui_tmp_t type, if you want to store fire‐
214 wallgui temporary files in the /tmp directories.
215
216
217
218 Note: File context can be temporarily modified with the chcon command.
219 If you want to permanently change the file context you need to use the
220 semanage fcontext command. This will modify the SELinux labeling data‐
221 base. You will need to use restorecon to apply the labels.
222
223
225 semanage fcontext can also be used to manipulate default file context
226 mappings.
227
228 semanage permissive can also be used to manipulate whether or not a
229 process type is permissive.
230
231 semanage module can also be used to enable/disable/install/remove pol‐
232 icy modules.
233
234 semanage boolean can also be used to manipulate the booleans
235
236
237 system-config-selinux is a GUI tool available to customize SELinux pol‐
238 icy settings.
