6 devicekit_disk_selinux - Security Enhanced Linux Policy for the de‐
7 vicekit_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 de‐
25 vicekit_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, /usr/lib/udisks2/ud‐
31 isksd, /usr/libexec/udisks-daemon, /usr/lib/udev/udisks-part-id,
32 /usr/libexec/udisks2/udisksd, /usr/lib/udisks/udisks-daemon,
33 /usr/libexec/devkit-disks-daemon
34
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. de‐
57 vicekit_disk policy is extremely flexible and has several booleans that
58 allow you to manipulate the policy and run devicekit_disk with the
59 tightest access possible.
60 If you want to deny user domains applications to map a memory region as
64 both executable and writable, this is dangerous and the executable
65 should be reported in bugzilla, you must turn on the deny_execmem bool‐
66 ean. Enabled by default.
67 setsebool -P deny_execmem 1
69 If you want to control the ability to mmap a low area of the address
73 space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on
74 the mmap_low_allowed boolean. Disabled by default.
75 setsebool -P mmap_low_allowed 1
77 If you want to disable kernel module loading, you must turn on the se‐
81 cure_mode_insmod boolean. Enabled by default.
82 setsebool -P secure_mode_insmod 1
84 If you want to allow unconfined executables to make their heap memory
88 executable. Doing this is a really bad idea. Probably indicates a
89 badly coded executable, but could indicate an attack. This executable
90 should be reported in bugzilla, you must turn on the selinuxuser_ex‐
91 echeap boolean. Disabled by default.
92 setsebool -P selinuxuser_execheap 1
94 If you want to allow unconfined executables to make their stack exe‐
98 cutable. This should never, ever be necessary. Probably indicates a
99 badly coded executable, but could indicate an attack. This executable
100 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
101 stack boolean. Enabled by default.
102 setsebool -P selinuxuser_execstack 1

108 The SELinux process type devicekit_disk_t can manage files labeled with
109 the following file types. The paths listed are the default paths for
110 these file types. Note the processes UID still need to have DAC per‐
111 missions.
112 file_type
114 all files on the system
116
119 SELinux requires files to have an extended attribute to define the file
120 type.
121 You can see the context of a file using the -Z option to ls
123 Policy governs the access confined processes have to these files.
125 SELinux devicekit_disk policy is very flexible allowing users to setup
126 their devicekit_disk processes in as secure a method as possible.
127 The following file types are defined for devicekit_disk:
129 devicekit_disk_exec_t
133 - Set files with the devicekit_disk_exec_t type, if you want to transi‐
135 tion an executable to the devicekit_disk_t domain.
136 Paths:
139 /lib/udisks2/udisksd, /lib/udev/udisks-part-id, /usr/lib/ud‐
140 isks2/udisksd, /usr/libexec/udisks-daemon, /usr/lib/udev/udisks-
141 part-id, /usr/libexec/udisks2/udisksd, /usr/lib/udisks/udisks-dae‐
142 mon, /usr/libexec/devkit-disks-daemon
143 Note: File context can be temporarily modified with the chcon command.
146 If you want to permanently change the file context you need to use the
147 semanage fcontext command. This will modify the SELinux labeling data‐
148 base. You will need to use restorecon to apply the labels.
149
152 semanage fcontext can also be used to manipulate default file context
153 mappings.
154 semanage permissive can also be used to manipulate whether or not a
156 process type is permissive.
157 semanage module can also be used to enable/disable/install/remove pol‐
159 icy modules.
160 semanage boolean can also be used to manipulate the booleans
162 system-config-selinux is a GUI tool available to customize SELinux pol‐
165 icy settings.
