6 devicekit_disk_selinux - Security Enhanced Linux Policy for the
7 devicekit_disk processes
8
10 Security-Enhanced Linux secures the devicekit_disk processes via flexi‐
11 ble mandatory access control.
12 The devicekit_disk processes execute with the devicekit_disk_t SELinux
14 type. You can check if you have these processes running by executing
15 the ps command with the -Z qualifier.
16 For example:
18 ps -eZ | grep devicekit_disk_t
20
24 The devicekit_disk_t SELinux type can be entered via the
25 devicekit_disk_exec_t file type.
26 The default entrypoint paths for the devicekit_disk_t domain are the
28 following:
29 /lib/udisks2/udisksd, /lib/udev/udisks-part-id,
31 /usr/lib/udisks2/udisksd, /usr/libexec/udisks-daemon,
32 /usr/lib/udev/udisks-part-id, /usr/libexec/udisks2/udisksd,
33 /usr/lib/udisks/udisks-daemon, /usr/libexec/devkit-disks-daemon

36 SELinux defines process types (domains) for each process running on the
37 system
38 You can see the context of a process using the -Z option to ps
40 Policy governs the access confined processes have to files. SELinux
42 devicekit_disk policy is very flexible allowing users to setup their
43 devicekit_disk processes in as secure a method as possible.
44 The following process types are defined for devicekit_disk:
46 devicekit_disk_t
48 Note: semanage permissive -a devicekit_disk_t can be used to make the
50 process type devicekit_disk_t permissive. SELinux does not deny access
51 to permissive process types, but the AVC (SELinux denials) messages are
52 still generated.
53
56 SELinux policy is customizable based on least access required.
57 devicekit_disk policy is extremely flexible and has several booleans
58 that allow you to manipulate the policy and run devicekit_disk with the
59 tightest access possible.
60 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 setsebool -P authlogin_nsswitch_use_ldap 1
68 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 setsebool -P deny_execmem 1
77 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 setsebool -P fips_mode 1
84 If you want to allow confined applications to run with kerberos, you
88 must turn on the kerberos_enabled boolean. Disabled by default.
89 setsebool -P kerberos_enabled 1
91 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 setsebool -P mmap_low_allowed 1
99 If you want to allow system to run with NIS, you must turn on the
103 nis_enabled boolean. Disabled by default.
104 setsebool -P nis_enabled 1
106 If you want to allow confined applications to use nscd shared memory,
110 you must turn on the nscd_use_shm boolean. Disabled by default.
111 setsebool -P nscd_use_shm 1
113 If you want to disable kernel module loading, you must turn on the
117 secure_mode_insmod boolean. Enabled by default.
118 setsebool -P secure_mode_insmod 1
120 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 setsebool -P selinuxuser_execheap 1
130 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. Disabled by default.
138 setsebool -P selinuxuser_execstack 1

144 The SELinux process type devicekit_disk_t can manage files labeled with
145 the following file types. The paths listed are the default paths for
146 these file types. Note the processes UID still need to have DAC per‐
147 missions.
148 file_type
150 all files on the system
152
155 SELinux requires files to have an extended attribute to define the file
156 type.
157 You can see the context of a file using the -Z option to ls
159 Policy governs the access confined processes have to these files.
161 SELinux devicekit_disk policy is very flexible allowing users to setup
162 their devicekit_disk processes in as secure a method as possible.
163 The following file types are defined for devicekit_disk:
165 devicekit_disk_exec_t
169 - Set files with the devicekit_disk_exec_t type, if you want to transi‐
171 tion an executable to the devicekit_disk_t domain.
172 Paths:
175 /lib/udisks2/udisksd, /lib/udev/udisks-part-id,
176 /usr/lib/udisks2/udisksd, /usr/libexec/udisks-daemon,
177 /usr/lib/udev/udisks-part-id, /usr/libexec/udisks2/udisksd,
178 /usr/lib/udisks/udisks-daemon, /usr/libexec/devkit-disks-daemon
179 Note: File context can be temporarily modified with the chcon command.
182 If you want to permanently change the file context you need to use the
183 semanage fcontext command. This will modify the SELinux labeling data‐
184 base. You will need to use restorecon to apply the labels.
185
188 semanage fcontext can also be used to manipulate default file context
189 mappings.
190 semanage permissive can also be used to manipulate whether or not a
192 process type is permissive.
193 semanage module can also be used to enable/disable/install/remove pol‐
195 icy modules.
196 semanage boolean can also be used to manipulate the booleans
198 system-config-selinux is a GUI tool available to customize SELinux pol‐
201 icy settings.
