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 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 For example:
18 ps -eZ | grep vmtools_unconfined_t
20
24 The vmtools_unconfined_t SELinux type can be entered via the
25 shell_exec_t, vmtools_unconfined_exec_t file types.
26 The default entrypoint paths for the vmtools_unconfined_t domain are
28 the following:
29 /bin/d?ash, /bin/ksh.*, /bin/zsh.*, /usr/bin/d?ash, /usr/bin/ksh.*,
31 /usr/bin/zsh.*, /bin/esh, /bin/bash, /bin/fish, /bin/mksh, /bin/sash,
32 /bin/tcsh, /bin/yash, /bin/bash2, /usr/bin/esh, /sbin/nologin,
33 /usr/bin/bash, /usr/bin/fish, /usr/bin/mksh, /usr/bin/sash,
34 /usr/bin/tcsh, /usr/bin/yash, /usr/bin/bash2, /usr/sbin/sesh,
35 /usr/sbin/smrsh, /usr/bin/scponly, /usr/libexec/sesh, /usr/sbin/nolo‐
36 gin, /usr/bin/git-shell, /usr/sbin/scponlyc, /usr/libexec/sudo/sesh,
37 /usr/bin/cockpit-bridge, /usr/libexec/cockpit-agent, /usr/libexec/git-
38 core/git-shell, /etc/vmware-tools(/.*)?

41 SELinux defines process types (domains) for each process running on the
42 system
43 You can see the context of a process using the -Z option to ps
45 Policy governs the access confined processes have to files. SELinux
47 vmtools_unconfined policy is very flexible allowing users to setup
48 their vmtools_unconfined processes in as secure a method as possible.
49 The following process types are defined for vmtools_unconfined:
51 vmtools_unconfined_t
53 Note: semanage permissive -a vmtools_unconfined_t can be used to make
55 the process type vmtools_unconfined_t permissive. SELinux does not deny
56 access to permissive process types, but the AVC (SELinux denials) mes‐
57 sages are still generated.
58
61 SELinux policy is customizable based on least access required.
62 vmtools_unconfined policy is extremely flexible and has several bool‐
63 eans that allow you to manipulate the policy and run vmtools_unconfined
64 with the tightest access possible.
65 If you want to deny user domains applications to map a memory region as
69 both executable and writable, this is dangerous and the executable
70 should be reported in bugzilla, you must turn on the deny_execmem bool‐
71 ean. Enabled by default.
72 setsebool -P deny_execmem 1
74 If you want to allow all domains to execute in fips_mode, you must turn
78 on the fips_mode boolean. Enabled by default.
79 setsebool -P fips_mode 1
81 If you want to control the ability to mmap a low area of the address
85 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
86 the mmap_low_allowed boolean. Disabled by default.
87 setsebool -P mmap_low_allowed 1
89 If you want to disable kernel module loading, you must turn on the
93 secure_mode_insmod boolean. Enabled by default.
94 setsebool -P secure_mode_insmod 1
96 If you want to allow unconfined executables to make their heap memory
100 executable. Doing this is a really bad idea. Probably indicates a
101 badly coded executable, but could indicate an attack. This executable
102 should be reported in bugzilla, you must turn on the selin‐
103 uxuser_execheap boolean. Disabled by default.
104 setsebool -P selinuxuser_execheap 1
106 If you want to allow unconfined executables to make their stack exe‐
110 cutable. This should never, ever be necessary. Probably indicates a
111 badly coded executable, but could indicate an attack. This executable
112 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
113 stack boolean. Disabled by default.
114 setsebool -P selinuxuser_execstack 1

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