NAME

6       devicekit_selinux  -  Security  Enhanced Linux Policy for the devicekit
7       processes
8

DESCRIPTION

10       Security-Enhanced Linux secures the devicekit  processes  via  flexible
11       mandatory access control.
12
13       The  devicekit processes execute with the devicekit_t SELinux type. You
14       can check if you have these processes running by executing the ps  com‐
15       mand with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep devicekit_t
20
21
22

ENTRYPOINTS

24       The  devicekit_t  SELinux  type can be entered via the devicekit_exec_t
25       file type.
26
27       The default entrypoint paths for the devicekit_t domain are the follow‐
28       ing:
29
30       /usr/bin/udisksctl, /usr/libexec/devkit-daemon
31

PROCESS TYPES

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

BOOLEANS

53       SELinux   policy  is  customizable  based  on  least  access  required.
54       devicekit policy is extremely flexible and has  several  booleans  that
55       allow  you to manipulate the policy and run devicekit with the tightest
56       access possible.
57
58
59
60       If you want to deny user domains applications to map a memory region as
61       both  executable  and  writable,  this  is dangerous and the executable
62       should be reported in bugzilla, you must turn on the deny_execmem bool‐
63       ean. Enabled by default.
64
65       setsebool -P deny_execmem 1
66
67
68
69       If you want to allow all domains to execute in fips_mode, you must turn
70       on the fips_mode boolean. Enabled by default.
71
72       setsebool -P fips_mode 1
73
74
75
76       If you want to control the ability to mmap a low area  of  the  address
77       space,  as  configured  by /proc/sys/vm/mmap_min_addr, you must turn on
78       the mmap_low_allowed boolean. Disabled by default.
79
80       setsebool -P mmap_low_allowed 1
81
82
83
84       If you want to disable kernel module loading,  you  must  turn  on  the
85       secure_mode_insmod boolean. Enabled by default.
86
87       setsebool -P secure_mode_insmod 1
88
89
90
91       If  you  want to allow unconfined executables to make their heap memory
92       executable.  Doing this is a really  bad  idea.  Probably  indicates  a
93       badly  coded  executable, but could indicate an attack. This executable
94       should  be  reported  in  bugzilla,  you  must  turn  on   the   selin‐
95       uxuser_execheap boolean. Disabled by default.
96
97       setsebool -P selinuxuser_execheap 1
98
99
100
101       If  you  want  to allow unconfined executables to make their stack exe‐
102       cutable.  This should never, ever be necessary.  Probably  indicates  a
103       badly  coded  executable, but could indicate an attack. This executable
104       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
105       stack boolean. Enabled by default.
106
107       setsebool -P selinuxuser_execstack 1
108

MANAGED FILES

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

FILE CONTEXTS

122       SELinux requires files to have an extended attribute to define the file
123       type.
124
125       You can see the context of a file using the -Z option to ls
126
127       Policy governs the access  confined  processes  have  to  these  files.
128       SELinux devicekit policy is very flexible allowing users to setup their
129       devicekit processes in as secure a method as possible.
130
131       STANDARD FILE CONTEXT
132
133       SELinux defines the file context types for the devicekit, if you wanted
134       to store files with these types in a diffent paths, you need to execute
135       the semanage command  to  sepecify  alternate  labeling  and  then  use
136       restorecon to put the labels on disk.
137
138       semanage  fcontext  -a  -t  devicekit_var_log_t  '/srv/mydevicekit_con‐
139       tent(/.*)?'
140       restorecon -R -v /srv/mydevicekit_content
141
142       Note: SELinux often uses regular expressions  to  specify  labels  that
143       match multiple files.
144
145       The following file types are defined for devicekit:
146
147
148
149       devicekit_disk_exec_t
150
151       - Set files with the devicekit_disk_exec_t type, if you want to transi‐
152       tion an executable to the devicekit_disk_t domain.
153
154
155       Paths:
156            /lib/udisks2/udisksd,                    /lib/udev/udisks-part-id,
157            /usr/lib/udisks2/udisksd,              /usr/libexec/udisks-daemon,
158            /usr/lib/udev/udisks-part-id,        /usr/libexec/udisks2/udisksd,

160
161
162       devicekit_exec_t
163
164       -  Set  files with the devicekit_exec_t type, if you want to transition
165       an executable to the devicekit_t domain.
166
167
168       Paths:
169            /usr/bin/udisksctl, /usr/libexec/devkit-daemon
170
171
172       devicekit_power_exec_t
173
174       - Set files with the devicekit_power_exec_t type, if you want to  tran‐
175       sition an executable to the devicekit_power_t domain.
176
177
178       Paths:
179            /usr/libexec/upowerd,                     /usr/lib/upower/upowerd,
180            /usr/libexec/devkit-power-daemon
181
182
183       devicekit_tmp_t
184
185       - Set files with  the  devicekit_tmp_t  type,  if  you  want  to  store
186       devicekit temporary files in the /tmp directories.
187
188
189
190       devicekit_var_lib_t
191
192       - Set files with the devicekit_var_lib_t type, if you want to store the
193       devicekit files under the /var/lib directory.
194
195
196       Paths:
197            /var/lib/udisks.*, /var/lib/upower(/.*)?, /var/lib/DeviceKit-.*
198
199
200       devicekit_var_log_t
201
202       - Set files with the devicekit_var_log_t type, if you want to treat the
203       data  as  devicekit  var  log  data,  usually stored under the /var/log
204       directory.
205
206
207       Paths:
208            /var/log/pm-suspend.log.*, /var/log/pm-powersave.log.*
209
210
211       devicekit_var_run_t
212
213       - Set files with the devicekit_var_run_t type, if you want to store the
214       devicekit files under the /run or /var/run directory.
215
216
217       Paths:
218            /var/run/udisks.*,  /var/run/devkit(/.*)?,  /var/run/upower(/.*)?,
219            /var/run/pm-utils(/.*)?, /var/run/DeviceKit-disks(/.*)?
220
221
222       Note: File context can be temporarily modified with the chcon  command.
223       If  you want to permanently change the file context you need to use the
224       semanage fcontext command.  This will modify the SELinux labeling data‐
225       base.  You will need to use restorecon to apply the labels.
226
227

COMMANDS

229       semanage  fcontext  can also be used to manipulate default file context
230       mappings.
231
232       semanage permissive can also be used to manipulate  whether  or  not  a
233       process type is permissive.
234
235       semanage  module can also be used to enable/disable/install/remove pol‐
236       icy modules.
237
238       semanage boolean can also be used to manipulate the booleans
239
240
241       system-config-selinux is a GUI tool available to customize SELinux pol‐
242       icy settings.
