NAME

6       unconfined_mount_selinux  -  Security Enhanced Linux Policy for the un‐
7       confined_mount processes
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  unconfined_mount  processes  via
11       flexible mandatory access control.
12
13       The  unconfined_mount  processes  execute  with  the unconfined_mount_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 unconfined_mount_t
20
21
22

ENTRYPOINTS

24       The unconfined_mount_t SELinux type can be entered via the mount_exec_t
25       file type.
26
27       The default entrypoint paths for the unconfined_mount_t domain are  the
28       following:
29
30       /bin/mount.*,     /bin/umount.*,     /sbin/mount.*,     /sbin/umount.*,
31       /usr/bin/mount.*,         /usr/bin/umount.*,         /usr/sbin/mount.*,
32       /usr/sbin/umount.*
33

PROCESS TYPES

35       SELinux defines process types (domains) for each process running on the
36       system
37
38       You can see the context of a process using the -Z option to ps
39
40       Policy governs the access confined processes have  to  files.   SELinux
41       unconfined_mount  policy is very flexible allowing users to setup their
42       unconfined_mount processes in as secure a method as possible.
43
44       The following process types are defined for unconfined_mount:
45
46       unconfined_mount_t
47
48       Note: semanage permissive -a unconfined_mount_t can be used to make the
49       process  type  unconfined_mount_t permissive. SELinux does not deny ac‐
50       cess to permissive process types, but the AVC  (SELinux  denials)  mes‐
51       sages are still generated.
52
53

BOOLEANS

55       SELinux  policy is customizable based on least access required.  uncon‐
56       fined_mount policy is extremely flexible and has several booleans  that
57       allow  you  to  manipulate the policy and run unconfined_mount with the
58       tightest access possible.
59
60
61
62       If you want to deny user domains applications to map a memory region as
63       both  executable  and  writable,  this  is dangerous and the executable
64       should be reported in bugzilla, you must turn on the deny_execmem bool‐
65       ean. Disabled by default.
66
67       setsebool -P deny_execmem 1
68
69
70
71       If  you  want  to control the ability to mmap a low area of the address
72       space, as configured by /proc/sys/vm/mmap_min_addr, you  must  turn  on
73       the mmap_low_allowed boolean. Disabled by default.
74
75       setsebool -P mmap_low_allowed 1
76
77
78
79       If  you want to disable kernel module loading, you must turn on the se‐
80       cure_mode_insmod boolean. Disabled by default.
81
82       setsebool -P secure_mode_insmod 1
83
84
85
86       If you want to allow unconfined executables to make their  heap  memory
87       executable.   Doing  this  is  a  really bad idea. Probably indicates a
88       badly coded executable, but could indicate an attack.  This  executable
89       should  be  reported  in bugzilla, you must turn on the selinuxuser_ex‐
90       echeap boolean. Disabled by default.
91
92       setsebool -P selinuxuser_execheap 1
93
94
95
96       If you want to allow unconfined executables to make  their  stack  exe‐
97       cutable.   This  should  never, ever be necessary. Probably indicates a
98       badly coded executable, but could indicate an attack.  This  executable
99       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
100       stack boolean. Enabled by default.
101
102       setsebool -P selinuxuser_execstack 1

MANAGED FILES

107       The SELinux process type unconfined_mount_t can  manage  files  labeled
108       with  the following file types.  The paths listed are the default paths
109       for these file types.  Note the processes UID still need  to  have  DAC
110       permissions.
111
112       file_type
113
114            all files on the system
115
116

COMMANDS

118       semanage  fcontext  can also be used to manipulate default file context
119       mappings.
120
121       semanage permissive can also be used to manipulate  whether  or  not  a
122       process type is permissive.
123
124       semanage  module can also be used to enable/disable/install/remove pol‐
125       icy modules.
126
127       semanage boolean can also be used to manipulate the booleans
128
129
130       system-config-selinux is a GUI tool available to customize SELinux pol‐
131       icy settings.
