NAME

6       unconfined_dbusd_selinux  -  Security  Enhanced  Linux  Policy  for the
7       unconfined_dbusd processes
8

DESCRIPTION

10       Security-Enhanced Linux  secures  the  unconfined_dbusd  processes  via
11       flexible mandatory access control.
12
13       The  unconfined_dbusd  processes  execute  with  the unconfined_dbusd_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_dbusd_t

ENTRYPOINTS

24       The unconfined_dbusd_t SELinux type can be entered via the dbusd_exec_t
25       file type.
26
27       The default entrypoint paths for the unconfined_dbusd_t domain are  the
28       following:
29
30       /usr/bin/dbus-daemon(-1)?,    /bin/dbus-daemon,   /usr/bin/dbus-broker,
31       /usr/bin/dbus-broker-launch,     /lib/dbus-1/dbus-daemon-launch-helper,
32       /usr/lib/dbus-1/dbus-daemon-launch-helper,    /usr/libexec/dbus-1/dbus-
33       daemon-launch-helper
34

PROCESS TYPES

36       SELinux defines process types (domains) for each process running on the
37       system
38
39       You can see the context of a process using the -Z option to ps
40
41       Policy  governs  the  access confined processes have to files.  SELinux
42       unconfined_dbusd policy is very flexible allowing users to setup  their
43       unconfined_dbusd processes in as secure a method as possible.
44
45       The following process types are defined for unconfined_dbusd:
46
47       unconfined_dbusd_t
48
49       Note: semanage permissive -a unconfined_dbusd_t can be used to make the
50       process type  unconfined_dbusd_t  permissive.  SELinux  does  not  deny
51       access  to permissive process types, but the AVC (SELinux denials) mes‐
52       sages are still generated.
53
54

BOOLEANS

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

MANAGED FILES

108       The  SELinux  process  type unconfined_dbusd_t can manage files labeled
109       with the following file types.  The paths listed are the default  paths
110       for  these  file  types.  Note the processes UID still need to have DAC
111       permissions.
112
113       file_type
114
115            all files on the system
116
117

COMMANDS

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