6 devicekit_power_selinux - Security Enhanced Linux Policy for the de‐
7 vicekit_power processes
8
10 Security-Enhanced Linux secures the devicekit_power processes via flex‐
11 ible mandatory access control.
12 The devicekit_power processes execute with the devicekit_power_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 For example:
18 ps -eZ | grep devicekit_power_t
20
24 The devicekit_power_t SELinux type can be entered via the de‐
25 vicekit_power_exec_t file type.
26 The default entrypoint paths for the devicekit_power_t domain are the
28 following:
29 /usr/libexec/upowerd, /usr/lib/upower/upowerd, /usr/libexec/devkit-
31 power-daemon
32
34 SELinux defines process types (domains) for each process running on the
35 system
36 You can see the context of a process using the -Z option to ps
38 Policy governs the access confined processes have to files. SELinux
40 devicekit_power policy is very flexible allowing users to setup their
41 devicekit_power processes in as secure a method as possible.
42 The following process types are defined for devicekit_power:
44 devicekit_power_t
46 Note: semanage permissive -a devicekit_power_t can be used to make the
48 process type devicekit_power_t permissive. SELinux does not deny access
49 to permissive process types, but the AVC (SELinux denials) messages are
50 still generated.
51
54 SELinux policy is customizable based on least access required. de‐
55 vicekit_power policy is extremely flexible and has several booleans
56 that allow you to manipulate the policy and run devicekit_power with
57 the tightest access possible.
58 If you want to dontaudit all daemons scheduling requests (setsched,
62 sys_nice), you must turn on the daemons_dontaudit_scheduling boolean.
63 Enabled by default.
64 setsebool -P daemons_dontaudit_scheduling 1
66 If you want to deny user domains applications to map a memory region as
70 both executable and writable, this is dangerous and the executable
71 should be reported in bugzilla, you must turn on the deny_execmem bool‐
72 ean. Disabled by default.
73 setsebool -P deny_execmem 1
75 If you want to control the ability to mmap a low area of the address
79 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
80 the mmap_low_allowed boolean. Disabled by default.
81 setsebool -P mmap_low_allowed 1
83 If you want to allow system to run with NIS, you must turn on the
87 nis_enabled boolean. Disabled by default.
88 setsebool -P nis_enabled 1
90 If you want to disable kernel module loading, you must turn on the se‐
94 cure_mode_insmod boolean. Disabled by default.
95 setsebool -P secure_mode_insmod 1
97 If you want to allow unconfined executables to make their heap memory
101 executable. Doing this is a really bad idea. Probably indicates a
102 badly coded executable, but could indicate an attack. This executable
103 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
104 echeap boolean. Disabled by default.
105 setsebool -P selinuxuser_execheap 1
107 If you want to allow unconfined executables to make their stack exe‐
111 cutable. This should never, ever be necessary. Probably indicates a
112 badly coded executable, but could indicate an attack. This executable
113 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
114 stack boolean. Enabled by default.
115 setsebool -P selinuxuser_execstack 1

121 The SELinux process type devicekit_power_t can manage files labeled
122 with the following file types. The paths listed are the default paths
123 for these file types. Note the processes UID still need to have DAC
124 permissions.
125 file_type
127 all files on the system
129
132 SELinux requires files to have an extended attribute to define the file
133 type.
134 You can see the context of a file using the -Z option to ls
136 Policy governs the access confined processes have to these files.
138 SELinux devicekit_power policy is very flexible allowing users to setup
139 their devicekit_power processes in as secure a method as possible.
140 STANDARD FILE CONTEXT
142 SELinux defines the file context types for the devicekit_power, if you
144 wanted to store files with these types in a different paths, you need
145 to execute the semanage command to specify alternate labeling and then
146 use restorecon to put the labels on disk.
147 semanage fcontext -a -t devicekit_power_exec_t '/srv/de‐
149 vicekit_power/content(/.*)?'
150 restorecon -R -v /srv/mydevicekit_power_content
151 Note: SELinux often uses regular expressions to specify labels that
153 match multiple files.
154 The following file types are defined for devicekit_power:
156 devicekit_power_exec_t
160 - Set files with the devicekit_power_exec_t type, if you want to tran‐
162 sition an executable to the devicekit_power_t domain.
163 Paths:
166 /usr/libexec/upowerd, /usr/lib/upower/upowerd, /usr/libexec/de‐
167 vkit-power-daemon
168 Note: File context can be temporarily modified with the chcon command.
171 If you want to permanently change the file context you need to use the
172 semanage fcontext command. This will modify the SELinux labeling data‐
173 base. You will need to use restorecon to apply the labels.
174
177 semanage fcontext can also be used to manipulate default file context
178 mappings.
179 semanage permissive can also be used to manipulate whether or not a
181 process type is permissive.
182 semanage module can also be used to enable/disable/install/remove pol‐
184 icy modules.
185 semanage boolean can also be used to manipulate the booleans
187 system-config-selinux is a GUI tool available to customize SELinux pol‐
190 icy settings.
