6 vmtools_unconfined_selinux - Security Enhanced Linux Policy for the
7 vmtools_unconfined processes
8
10 Security-Enhanced Linux secures the vmtools_unconfined processes via
11 flexible mandatory access control.
12
13 The vmtools_unconfined processes execute with the vmtools_unconfined_t
14 SELinux type. You can check if you have these processes running by exe‐
15 cuting the ps command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep vmtools_unconfined_t
20
21
22
24 The vmtools_unconfined_t SELinux type can be entered via the
25 vmtools_unconfined_exec_t file type.
26
27 The default entrypoint paths for the vmtools_unconfined_t domain are
28 the following:
29
30 /etc/vmware-tools(/.*)?
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 vmtools_unconfined policy is very flexible allowing users to setup
40 their vmtools_unconfined processes in as secure a method as possible.
41
42 The following process types are defined for vmtools_unconfined:
43
44 vmtools_unconfined_t
45
46 Note: semanage permissive -a vmtools_unconfined_t can be used to make
47 the process type vmtools_unconfined_t permissive. SELinux does not deny
48 access to permissive process types, but the AVC (SELinux denials) mes‐
49 sages are still generated.
50
51
53 SELinux policy is customizable based on least access required.
54 vmtools_unconfined policy is extremely flexible and has several bool‐
55 eans that allow you to manipulate the policy and run vmtools_unconfined
56 with the tightest access possible.
57
58
59
60 If you want to deny user domains applications to map a memory region as
61 both executable and writable, this is dangerous and the executable
62 should be reported in bugzilla, you must turn on the deny_execmem bool‐
63 ean. Enabled by default.
64
65 setsebool -P deny_execmem 1
66
67
68
69 If you want to allow all domains to execute in fips_mode, you must turn
70 on the fips_mode boolean. Enabled by default.
71
72 setsebool -P fips_mode 1
73
74
75
76 If you want to control the ability to mmap a low area of the address
77 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
78 the mmap_low_allowed boolean. Disabled by default.
79
80 setsebool -P mmap_low_allowed 1
81
82
83
84 If you want to disable kernel module loading, you must turn on the
85 secure_mode_insmod boolean. Enabled by default.
86
87 setsebool -P secure_mode_insmod 1
88
89
90
91 If you want to allow unconfined executables to make their heap memory
92 executable. Doing this is a really bad idea. Probably indicates a
93 badly coded executable, but could indicate an attack. This executable
94 should be reported in bugzilla, you must turn on the selin‐
95 uxuser_execheap boolean. Disabled by default.
96
97 setsebool -P selinuxuser_execheap 1
98
99
100
101 If you want to allow unconfined executables to make their stack exe‐
102 cutable. This should never, ever be necessary. Probably indicates a
103 badly coded executable, but could indicate an attack. This executable
104 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
105 stack boolean. Enabled by default.
106
107 setsebool -P selinuxuser_execstack 1
108

112 The SELinux process type vmtools_unconfined_t can manage files labeled
113 with the following file types. The paths listed are the default paths
114 for these file types. Note the processes UID still need to have DAC
115 permissions.
116
117 file_type
118
119 all files on the system
120
121
123 SELinux requires files to have an extended attribute to define the file
124 type.
125
126 You can see the context of a file using the -Z option to ls
127
128 Policy governs the access confined processes have to these files.
129 SELinux vmtools_unconfined policy is very flexible allowing users to
130 setup their vmtools_unconfined processes in as secure a method as pos‐
131 sible.
132
133 The following file types are defined for vmtools_unconfined:
134
135
136
137 vmtools_unconfined_exec_t
138
139 - Set files with the vmtools_unconfined_exec_t type, if you want to
140 transition an executable to the vmtools_unconfined_t domain.
141
142
143
144 Note: File context can be temporarily modified with the chcon command.
145 If you want to permanently change the file context you need to use the
146 semanage fcontext command. This will modify the SELinux labeling data‐
147 base. You will need to use restorecon to apply the labels.
148
149
151 semanage fcontext can also be used to manipulate default file context
152 mappings.
153
154 semanage permissive can also be used to manipulate whether or not a
155 process type is permissive.
156
157 semanage module can also be used to enable/disable/install/remove pol‐
158 icy modules.
159
160 semanage boolean can also be used to manipulate the booleans
161
162
163 system-config-selinux is a GUI tool available to customize SELinux pol‐
164 icy settings.
