NAME

6       vmtools_unconfined_selinux  -  Security  Enhanced  Linux Policy for the
7       vmtools_unconfined processes
8

DESCRIPTION

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

ENTRYPOINTS

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

PROCESS TYPES

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.

51

BOOLEANS

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

MANAGED FILES

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

FILE CONTEXTS

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

COMMANDS

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.
