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
25 devicekit_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.
55 devicekit_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 allow users to resolve user passwd entries directly from
62 ldap rather then using a sssd server, you must turn on the authlo‐
63 gin_nsswitch_use_ldap boolean. Disabled by default.
64 setsebool -P authlogin_nsswitch_use_ldap 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. Enabled by default.
73 setsebool -P deny_execmem 1
75 If you want to allow all domains to execute in fips_mode, you must turn
79 on the fips_mode boolean. Enabled by default.
80 setsebool -P fips_mode 1
82 If you want to allow confined applications to run with kerberos, you
86 must turn on the kerberos_enabled boolean. Enabled by default.
87 setsebool -P kerberos_enabled 1
89 If you want to control the ability to mmap a low area of the address
93 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
94 the mmap_low_allowed boolean. Disabled by default.
95 setsebool -P mmap_low_allowed 1
97 If you want to allow system to run with NIS, you must turn on the
101 nis_enabled boolean. Disabled by default.
102 setsebool -P nis_enabled 1
104 If you want to allow confined applications to use nscd shared memory,
108 you must turn on the nscd_use_shm boolean. Disabled by default.
109 setsebool -P nscd_use_shm 1
111 If you want to disable kernel module loading, you must turn on the
115 secure_mode_insmod boolean. Enabled by default.
116 setsebool -P secure_mode_insmod 1
118 If you want to allow unconfined executables to make their heap memory
122 executable. Doing this is a really bad idea. Probably indicates a
123 badly coded executable, but could indicate an attack. This executable
124 should be reported in bugzilla, you must turn on the selin‐
125 uxuser_execheap boolean. Disabled by default.
126 setsebool -P selinuxuser_execheap 1
128 If you want to allow unconfined executables to make their stack exe‐
132 cutable. This should never, ever be necessary. Probably indicates a
133 badly coded executable, but could indicate an attack. This executable
134 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
135 stack boolean. Enabled by default.
136 setsebool -P selinuxuser_execstack 1
138
142 The SELinux process type devicekit_power_t can manage files labeled
143 with the following file types. The paths listed are the default paths
144 for these file types. Note the processes UID still need to have DAC
145 permissions.
146 file_type
148 all files on the system
150
153 SELinux requires files to have an extended attribute to define the file
154 type.
155 You can see the context of a file using the -Z option to ls
157 Policy governs the access confined processes have to these files.
159 SELinux devicekit_power policy is very flexible allowing users to setup
160 their devicekit_power processes in as secure a method as possible.
161 The following file types are defined for devicekit_power:
163 devicekit_power_exec_t
167 - Set files with the devicekit_power_exec_t type, if you want to tran‐
169 sition an executable to the devicekit_power_t domain.
170 Paths:
173 /usr/libexec/upowerd, /usr/lib/upower/upowerd,
174 /usr/libexec/devkit-power-daemon
175 Note: File context can be temporarily modified with the chcon command.
178 If you want to permanently change the file context you need to use the
179 semanage fcontext command. This will modify the SELinux labeling data‐
180 base. You will need to use restorecon to apply the labels.
181
184 semanage fcontext can also be used to manipulate default file context
185 mappings.
186 semanage permissive can also be used to manipulate whether or not a
188 process type is permissive.
189 semanage module can also be used to enable/disable/install/remove pol‐
191 icy modules.
192 semanage boolean can also be used to manipulate the booleans
194 system-config-selinux is a GUI tool available to customize SELinux pol‐
197 icy settings.
