6 devicekit_power_selinux - Security Enhanced Linux Policy for the
7 devicekit_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 file_type,
25 unlabeled_t, proc_type, filesystem_type, devicekit_power_exec_t,
26 mtrr_device_t, sysctl_type file types.
27 The default entrypoint paths for the devicekit_power_t domain are the
29 following:
30 all files on the system, /usr/libexec/upowerd, /usr/libexec/devkit-
32 power-daemon, /dev/cpu/mtrr
33
35 SELinux defines process types (domains) for each process running on the
36 system
37 You can see the context of a process using the -Z option to ps
39 Policy governs the access confined processes have to files. SELinux
41 devicekit_power policy is very flexible allowing users to setup their
42 devicekit_power processes in as secure a method as possible.
43 The following process types are defined for devicekit_power:
45 devicekit_power_t
47 Note: semanage permissive -a devicekit_power_t can be used to make the
49 process type devicekit_power_t permissive. SELinux does not deny access
50 to permissive process types, but the AVC (SELinux denials) messages are
51 still generated.
52
55 SELinux policy is customizable based on least access required.
56 devicekit_power policy is extremely flexible and has several booleans
57 that allow you to manipulate the policy and run devicekit_power with
58 the tightest access possible.
59 If you want to allow all daemons the ability to read/write terminals,
63 you must turn on the allow_daemons_use_tty boolean. Disabled by
64 default.
65 setsebool -P allow_daemons_use_tty 1
67 If you want to allow all domains to use other domains file descriptors,
71 you must turn on the allow_domain_fd_use boolean. Enabled by default.
72 setsebool -P allow_domain_fd_use 1
74 If you want to allow unconfined executables to make their heap memory
78 executable. Doing this is a really bad idea. Probably indicates a
79 badly coded executable, but could indicate an attack. This executable
80 should be reported in bugzilla, you must turn on the allow_execheap
81 boolean. Disabled by default.
82 setsebool -P allow_execheap 1
84 If you want to allow unconfined executables to map a memory region as
88 both executable and writable, this is dangerous and the executable
89 should be reported in bugzilla), you must turn on the allow_execmem
90 boolean. Enabled by default.
91 setsebool -P allow_execmem 1
93 If you want to allow all unconfined executables to use libraries
97 requiring text relocation that are not labeled textrel_shlib_t), you
98 must turn on the allow_execmod boolean. Enabled by default.
99 setsebool -P allow_execmod 1
101 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 allow_execstack
108 boolean. Enabled by default.
109 setsebool -P allow_execstack 1
111 If you want to allow confined applications to run with kerberos, you
115 must turn on the allow_kerberos boolean. Enabled by default.
116 setsebool -P allow_kerberos 1
118 If you want to allow sysadm to debug or ptrace all processes, you must
122 turn on the allow_ptrace boolean. Disabled by default.
123 setsebool -P allow_ptrace 1
125 If you want to allow system to run with NIS, you must turn on the
129 allow_ypbind boolean. Disabled by default.
130 setsebool -P allow_ypbind 1
132 If you want to allow all domains to have the kernel load modules, you
136 must turn on the domain_kernel_load_modules boolean. Disabled by
137 default.
138 setsebool -P domain_kernel_load_modules 1
140 If you want to allow all domains to execute in fips_mode, you must turn
144 on the fips_mode boolean. Enabled by default.
145 setsebool -P fips_mode 1
147 If you want to enable reading of urandom for all domains, you must turn
151 on the global_ssp boolean. Disabled by default.
152 setsebool -P global_ssp 1
154 If you want to allow certain domains to map low memory in the kernel,
158 you must turn on the mmap_low_allowed boolean. Disabled by default.
159 setsebool -P mmap_low_allowed 1
161 If you want to allow confined applications to use nscd shared memory,
165 you must turn on the nscd_use_shm boolean. Enabled by default.
166 setsebool -P nscd_use_shm 1
168 If you want to boolean to determine whether the system permits loading
172 policy, setting enforcing mode, and changing boolean values. Set this
173 to true and you have to reboot to set it back, you must turn on the
174 secure_mode_policyload boolean. Disabled by default.
175 setsebool -P secure_mode_policyload 1
177 If you want to support X userspace object manager, you must turn on the
181 xserver_object_manager boolean. Disabled by default.
182 setsebool -P xserver_object_manager 1
184
188 The SELinux process type devicekit_power_t can manage files labeled
189 with the following file types. The paths listed are the default paths
190 for these file types. Note the processes UID still need to have DAC
191 permissions.
192 file_type
194 all files on the system
196
199 SELinux requires files to have an extended attribute to define the file
200 type.
201 You can see the context of a file using the -Z option to ls
203 Policy governs the access confined processes have to these files.
205 SELinux devicekit_power policy is very flexible allowing users to setup
206 their devicekit_power processes in as secure a method as possible.
207 The following file types are defined for devicekit_power:
209 devicekit_power_exec_t
213 - Set files with the devicekit_power_exec_t type, if you want to tran‐
215 sition an executable to the devicekit_power_t domain.
216 Paths:
219 /usr/libexec/upowerd, /usr/libexec/devkit-power-daemon
220 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
229 semanage fcontext can also be used to manipulate default file context
230 mappings.
231 semanage permissive can also be used to manipulate whether or not a
233 process type is permissive.
234 semanage module can also be used to enable/disable/install/remove pol‐
236 icy modules.
237 semanage boolean can also be used to manipulate the booleans
239 system-config-selinux is a GUI tool available to customize SELinux pol‐
242 icy settings.
