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

22

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 allow users to resolve user passwd entries directly from
64       ldap rather then using a sssd server, you  must  turn  on  the  authlo‐
65       gin_nsswitch_use_ldap boolean. Disabled by default.
66
67       setsebool -P authlogin_nsswitch_use_ldap 1
68
69
70
71       If you want to deny user domains applications to map a memory region as
72       both executable and writable, this  is  dangerous  and  the  executable
73       should be reported in bugzilla, you must turn on the deny_execmem bool‐
74       ean. Enabled by default.
75
76       setsebool -P deny_execmem 1
77
78
79
80       If you want to allow all domains to execute in fips_mode, you must turn
81       on the fips_mode boolean. Enabled by default.
82
83       setsebool -P fips_mode 1
84
85
86
87       If  you  want  to allow confined applications to run with kerberos, you
88       must turn on the kerberos_enabled boolean. Enabled by default.
89
90       setsebool -P kerberos_enabled 1
91
92
93
94       If you want to control the ability to mmap a low area  of  the  address
95       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
96       the mmap_low_allowed boolean. Disabled by default.
97
98       setsebool -P mmap_low_allowed 1
99
100
101
102       If you want to allow system to run with  NIS,  you  must  turn  on  the
103       nis_enabled boolean. Disabled by default.
104
105       setsebool -P nis_enabled 1
106
107
108
109       If  you  want to allow confined applications to use nscd shared memory,
110       you must turn on the nscd_use_shm boolean. Enabled by default.
111
112       setsebool -P nscd_use_shm 1
113
114
115
116       If you want to disable kernel module loading,  you  must  turn  on  the
117       secure_mode_insmod boolean. Enabled by default.
118
119       setsebool -P secure_mode_insmod 1
120
121
122
123       If  you  want to allow unconfined executables to make their heap memory
124       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
125       badly  coded  executable, but could indicate an attack. This executable
126       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
127       uxuser_execheap boolean. Disabled by default.
128
129       setsebool -P selinuxuser_execheap 1
130
131
132
133       If  you  want  to allow unconfined executables to make their stack exe‐
134       cutable.  This should never, ever be necessary.  Probably  indicates  a
135       badly  coded  executable, but could indicate an attack. This executable
136       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
137       stack boolean. Enabled by default.
138
139       setsebool -P selinuxuser_execstack 1

MANAGED FILES

144       The  SELinux  process  type unconfined_dbusd_t can manage files labeled
145       with the following file types.  The paths listed are the default  paths
146       for  these  file  types.  Note the processes UID still need to have DAC
147       permissions.
148
149       file_type
150
151            all files on the system
152
153

COMMANDS

155       semanage fcontext can also be used to manipulate default  file  context
156       mappings.
157
158       semanage  permissive  can  also  be used to manipulate whether or not a
159       process type is permissive.
160
161       semanage module can also be used to enable/disable/install/remove  pol‐
162       icy modules.
163
164       semanage boolean can also be used to manipulate the booleans
165
166
167       system-config-selinux is a GUI tool available to customize SELinux pol‐
168       icy settings.
