6 vbetool_selinux - Security Enhanced Linux Policy for the vbetool pro‐
7 cesses
8
10 Security-Enhanced Linux secures the vbetool processes via flexible
11 mandatory access control.
12
13 The vbetool processes execute with the vbetool_t SELinux type. You can
14 check if you have these processes running by executing the ps command
15 with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep vbetool_t
20
21
22
24 The vbetool_t SELinux type can be entered via the vbetool_exec_t file
25 type.
26
27 The default entrypoint paths for the vbetool_t domain are the follow‐
28 ing:
29
30 /usr/sbin/vbetool
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 vbetool policy is very flexible allowing users to setup their vbetool
40 processes in as secure a method as possible.
41
42 The following process types are defined for vbetool:
43
44 vbetool_t
45
46 Note: semanage permissive -a vbetool_t can be used to make the process
47 type vbetool_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
51
53 SELinux policy is customizable based on least access required. vbetool
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run vbetool with the tightest access possi‐
56 ble.
57
58
59
60 If you want to allow all daemons the ability to read/write terminals,
61 you must turn on the allow_daemons_use_tty boolean. Disabled by
62 default.
63
64 setsebool -P allow_daemons_use_tty 1
65
66
67
68 If you want to allow all domains to use other domains file descriptors,
69 you must turn on the allow_domain_fd_use boolean. Enabled by default.
70
71 setsebool -P allow_domain_fd_use 1
72
73
74
75 If you want to allow sysadm to debug or ptrace all processes, you must
76 turn on the allow_ptrace boolean. Disabled by default.
77
78 setsebool -P allow_ptrace 1
79
80
81
82 If you want to allow all domains to have the kernel load modules, you
83 must turn on the domain_kernel_load_modules boolean. Disabled by
84 default.
85
86 setsebool -P domain_kernel_load_modules 1
87
88
89
90 If you want to allow all domains to execute in fips_mode, you must turn
91 on the fips_mode boolean. Enabled by default.
92
93 setsebool -P fips_mode 1
94
95
96
97 If you want to enable reading of urandom for all domains, you must turn
98 on the global_ssp boolean. Disabled by default.
99
100 setsebool -P global_ssp 1
101
102
103
104 If you want to allow certain domains to map low memory in the kernel,
105 you must turn on the mmap_low_allowed boolean. Disabled by default.
106
107 setsebool -P mmap_low_allowed 1
108
109

112 The SELinux process type vbetool_t can manage files labeled with the
113 following file types. The paths listed are the default paths for these
114 file types. Note the processes UID still need to have DAC permissions.

166 SELinux requires files to have an extended attribute to define the file
167 type.
168
169 You can see the context of a file using the -Z option to ls
170
171 Policy governs the access confined processes have to these files.
172 SELinux vbetool policy is very flexible allowing users to setup their
173 vbetool processes in as secure a method as possible.
174
175 The following file types are defined for vbetool:
176
177
178
179 vbetool_exec_t
180
181 - Set files with the vbetool_exec_t type, if you want to transition an
182 executable to the vbetool_t domain.
183
184
185
186 Note: File context can be temporarily modified with the chcon command.
187 If you want to permanently change the file context you need to use the
188 semanage fcontext command. This will modify the SELinux labeling data‐
189 base. You will need to use restorecon to apply the labels.
190
191
193 semanage fcontext can also be used to manipulate default file context
194 mappings.
195
196 semanage permissive can also be used to manipulate whether or not a
197 process type is permissive.
198
199 semanage module can also be used to enable/disable/install/remove pol‐
200 icy modules.
201
202 semanage boolean can also be used to manipulate the booleans
203
204
205 system-config-selinux is a GUI tool available to customize SELinux pol‐
206 icy settings.
