NAME

6       lockdev_selinux  -  Security Enhanced Linux Policy for the lockdev pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  lockdev  processes  via  flexible
11       mandatory access control.
12
13       The  lockdev processes execute with the lockdev_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep lockdev_t
20
21
22

ENTRYPOINTS

24       The  lockdev_t  SELinux type can be entered via the lockdev_exec_t file
25       type.
26
27       The default entrypoint paths for the lockdev_t domain are  the  follow‐
28       ing:
29
30       /usr/sbin/lockdev
31

PROCESS TYPES

33       SELinux defines process types (domains) for each process running on the
34       system
35
36       You can see the context of a process using the -Z option to ps
37
38       Policy governs the access confined processes have  to  files.   SELinux
39       lockdev  policy  is very flexible allowing users to setup their lockdev
40       processes in as secure a method as possible.
41
42       The following process types are defined for lockdev:
43
44       lockdev_t
45
46       Note: semanage permissive -a lockdev_t can be used to make the  process
47       type  lockdev_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.
50
51

BOOLEANS

53       SELinux policy is customizable based on least access required.  lockdev
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run lockdev with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you want to allow sysadm to debug or ptrace all processes, you must
68       turn on the allow_ptrace boolean. Disabled by default.
69
70       setsebool -P allow_ptrace 1
71
72
73
74       If you want to allow all domains to have the kernel load  modules,  you
75       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
76       default.
77
78       setsebool -P domain_kernel_load_modules 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If you want to enable reading of urandom for all domains, you must turn
90       on the global_ssp boolean. Disabled by default.
91
92       setsebool -P global_ssp 1
93

MANAGED FILES

97       The SELinux process type lockdev_t can manage files  labeled  with  the
98       following file types.  The paths listed are the default paths for these
99       file types.  Note the processes UID still need to have DAC permissions.
100
101       initrc_tmp_t
102
103
104       lockdev_lock_t
105
106
107       mnt_t
108
109            /mnt(/[^/]*)
110            /mnt(/[^/]*)?
111            /rhev(/[^/]*)?
112            /media(/[^/]*)
113            /media(/[^/]*)?
114            /etc/rhgb(/.*)?
115            /media/.hal-.*
116            /net
117            /afs
118            /rhev
119            /misc
120
121       tmp_t
122
123            /tmp
124            /usr/tmp
125            /var/tmp
126            /tmp-inst
127            /var/tmp-inst
128            /var/tmp/vi.recover

FILE CONTEXTS

132       SELinux requires files to have an extended attribute to define the file
133       type.
134
135       You can see the context of a file using the -Z option to ls
136
137       Policy  governs  the  access  confined  processes  have to these files.
138       SELinux lockdev policy is very flexible allowing users to  setup  their
139       lockdev processes in as secure a method as possible.
140
141       STANDARD FILE CONTEXT
142
143       SELinux  defines  the file context types for the lockdev, if you wanted
144       to store files with these types in a diffent paths, you need to execute
145       the  semanage  command  to  sepecify  alternate  labeling  and then use
146       restorecon to put the labels on disk.
147
148       semanage fcontext -a -t lockdev_lock_t '/srv/mylockdev_content(/.*)?'
149       restorecon -R -v /srv/mylockdev_content
150
151       Note: SELinux often uses regular expressions  to  specify  labels  that
152       match multiple files.
153
154       The following file types are defined for lockdev:
155
156
157
158       lockdev_exec_t
159
160       -  Set files with the lockdev_exec_t type, if you want to transition an
161       executable to the lockdev_t domain.
162
163
164
165       lockdev_lock_t
166
167       - Set files with the lockdev_lock_t type, if  you  want  to  treat  the
168       files as lockdev lock data, stored under the /var/lock directory
169
170
171
172       Note:  File context can be temporarily modified with the chcon command.
173       If you want to permanently change the file context you need to use  the
174       semanage fcontext command.  This will modify the SELinux labeling data‐
175       base.  You will need to use restorecon to apply the labels.
176
177

COMMANDS

179       semanage fcontext can also be used to manipulate default  file  context
180       mappings.
181
182       semanage  permissive  can  also  be used to manipulate whether or not a
183       process type is permissive.
184
185       semanage module can also be used to enable/disable/install/remove  pol‐
186       icy modules.
187
188       semanage boolean can also be used to manipulate the booleans
189
190
191       system-config-selinux is a GUI tool available to customize SELinux pol‐
192       icy settings.
