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.

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 execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1

66

MANAGED FILES

68       The  SELinux  process  type lockdev_t can manage files labeled with the
69       following file types.  The paths listed are the default paths for these
70       file types.  Note the processes UID still need to have DAC permissions.
71
72       lockdev_lock_t
73
74            /var/lock/lockdev(/.*)?
75
76

FILE CONTEXTS

78       SELinux requires files to have an extended attribute to define the file
79       type.
80
81       You can see the context of a file using the -Z option to ls
82
83       Policy governs the access  confined  processes  have  to  these  files.
84       SELinux  lockdev  policy is very flexible allowing users to setup their
85       lockdev processes in as secure a method as possible.
86
87       STANDARD FILE CONTEXT
88
89       SELinux defines the file context types for the lockdev, if  you  wanted
90       to store files with these types in a diffent paths, you need to execute
91       the semanage command  to  sepecify  alternate  labeling  and  then  use
92       restorecon to put the labels on disk.
93
94       semanage fcontext -a -t lockdev_lock_t '/srv/mylockdev_content(/.*)?'
95       restorecon -R -v /srv/mylockdev_content
96
97       Note:  SELinux  often  uses  regular expressions to specify labels that
98       match multiple files.
99
100       The following file types are defined for lockdev:
101
102
103
104       lockdev_exec_t
105
106       - Set files with the lockdev_exec_t type, if you want to transition  an
107       executable to the lockdev_t domain.
108
109
110
111       lockdev_lock_t
112
113       -  Set  files  with  the  lockdev_lock_t type, if you want to treat the
114       files as lockdev lock data, stored under the /var/lock directory
115
116
117
118       Note: File context can be temporarily modified with the chcon  command.
119       If  you want to permanently change the file context you need to use the
120       semanage fcontext command.  This will modify the SELinux labeling data‐
121       base.  You will need to use restorecon to apply the labels.
122
123

COMMANDS

125       semanage  fcontext  can also be used to manipulate default file context
126       mappings.
127
128       semanage permissive can also be used to manipulate  whether  or  not  a
129       process type is permissive.
130
131       semanage  module can also be used to enable/disable/install/remove pol‐
132       icy modules.
133
134       semanage boolean can also be used to manipulate the booleans
135
136
137       system-config-selinux is a GUI tool available to customize SELinux pol‐
138       icy settings.
