NAME

6       vmtools_helper_selinux   -  Security  Enhanced  Linux  Policy  for  the
7       vmtools_helper processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the vmtools_helper processes via flexi‐
11       ble mandatory access control.
12
13       The  vmtools_helper processes execute with the vmtools_helper_t SELinux
14       type. You can check if you have these processes  running  by  executing
15       the ps command with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep vmtools_helper_t
20

22

ENTRYPOINTS

24       The   vmtools_helper_t   SELinux   type   can   be   entered   via  the
25       vmtools_helper_exec_t file type.
26
27       The default entrypoint paths for the vmtools_helper_t  domain  are  the
28       following:
29
30       /usr/bin/vmware-user-suid-wrapper
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_helper  policy  is  very flexible allowing users to setup their
40       vmtools_helper processes in as secure a method as possible.
41
42       The following process types are defined for vmtools_helper:
43
44       vmtools_helper_t
45
46       Note: semanage permissive -a vmtools_helper_t can be used to  make  the
47       process  type vmtools_helper_t permissive. SELinux does not deny access
48       to permissive process types, but the AVC (SELinux denials) messages are
49       still generated.

51

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       vmtools_helper policy is extremely flexible and  has  several  booleans
55       that allow you to manipulate the policy and run vmtools_helper with the
56       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. Disabled by default.
106
107       setsebool -P selinuxuser_execstack 1

MANAGED FILES

112       The SELinux process type vmtools_helper_t can manage files labeled with
113       the following file types.  The paths listed are the default  paths  for
114       these  file  types.  Note the processes UID still need to have DAC per‐
115       missions.
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_helper policy is very flexible allowing users to  setup
130       their vmtools_helper processes in as secure a method as possible.
131
132       The following file types are defined for vmtools_helper:
133
134
135
136       vmtools_helper_exec_t
137
138       - Set files with the vmtools_helper_exec_t type, if you want to transi‐
139       tion an executable to the vmtools_helper_t domain.
140
141
142
143       Note: File context can be temporarily modified with the chcon  command.
144       If  you want to permanently change the file context you need to use the
145       semanage fcontext command.  This will modify the SELinux labeling data‐
146       base.  You will need to use restorecon to apply the labels.
147
148

COMMANDS

150       semanage  fcontext  can also be used to manipulate default file context
151       mappings.
152
153       semanage permissive can also be used to manipulate  whether  or  not  a
154       process type is permissive.
155
156       semanage  module can also be used to enable/disable/install/remove pol‐
157       icy modules.
158
159       semanage boolean can also be used to manipulate the booleans
160
161
162       system-config-selinux is a GUI tool available to customize SELinux pol‐
163       icy settings.
