NAME

6       unconfined_dbusd_selinux  -  Security Enhanced Linux Policy for the un‐
7       confined_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  ac‐
51       cess  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. Disabled 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 allow system to run with  NIS,  you  must  turn  on  the
81       nis_enabled boolean. Disabled by default.
82
83       setsebool -P nis_enabled 1
84
85
86
87       If  you want to disable kernel module loading, you must turn on the se‐
88       cure_mode_insmod boolean. Disabled by default.
89
90       setsebool -P secure_mode_insmod 1
91
92
93
94       If you want to allow unconfined executables to make their  heap  memory
95       executable.   Doing  this  is  a  really bad idea. Probably indicates a
96       badly coded executable, but could indicate an attack.  This  executable
97       should  be  reported  in bugzilla, you must turn on the selinuxuser_ex‐
98       echeap boolean. Disabled by default.
99
100       setsebool -P selinuxuser_execheap 1
101
102
103
104       If you want to allow unconfined executables to make  their  stack  exe‐
105       cutable.   This  should  never, ever be necessary. Probably indicates a
106       badly coded executable, but could indicate an attack.  This  executable
107       should  be reported in bugzilla, you must turn on the selinuxuser_exec‐
108       stack boolean. Enabled by default.
109
110       setsebool -P selinuxuser_execstack 1

MANAGED FILES

115       The SELinux process type unconfined_dbusd_t can  manage  files  labeled
116       with  the following file types.  The paths listed are the default paths
117       for these file types.  Note the processes UID still need  to  have  DAC
118       permissions.
119
120       file_type
121
122            all files on the system
123
124

COMMANDS

126       semanage  fcontext  can also be used to manipulate default file context
127       mappings.
128
129       semanage permissive can also be used to manipulate  whether  or  not  a
130       process type is permissive.
131
132       semanage  module can also be used to enable/disable/install/remove pol‐
133       icy modules.
134
135       semanage boolean can also be used to manipulate the booleans
136
137
138       system-config-selinux is a GUI tool available to customize SELinux pol‐
139       icy settings.
