NAME

6       loadkeys_selinux - Security Enhanced Linux Policy for the loadkeys pro‐
7       cesses
8

DESCRIPTION

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

ENTRYPOINTS

24       The loadkeys_t SELinux type can be entered via the loadkeys_exec_t file
25       type.
26
27       The default entrypoint paths for the loadkeys_t domain are the  follow‐
28       ing:
29
30       /bin/unikeys, /bin/loadkeys, /usr/bin/unikeys, /usr/bin/loadkeys
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       loadkeys policy is very flexible allowing users to setup their loadkeys
40       processes in as secure a method as possible.
41
42       The following process types are defined for loadkeys:
43
44       loadkeys_t
45
46       Note: semanage permissive -a loadkeys_t can be used to make the process
47       type  loadkeys_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.  load‐
54       keys policy is extremely flexible and has several booleans  that  allow
55       you  to manipulate the policy and run loadkeys with the tightest access
56       possible.
57
58
59
60       If you want to allow all daemons the ability to  read/write  terminals,
61       you must turn on the daemons_use_tty boolean. Disabled by default.
62
63       setsebool -P daemons_use_tty 1
64
65
66
67       If  you  want  to deny any process from ptracing or debugging any other
68       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
69       default.
70
71       setsebool -P deny_ptrace 1
72
73
74
75       If  you  want  to  allow  any  process  to mmap any file on system with
76       attribute file_type, you must turn on the  domain_can_mmap_files  bool‐
77       ean. Enabled by default.
78
79       setsebool -P domain_can_mmap_files 1
80
81
82
83       If  you want to allow all domains write to kmsg_device, while kernel is
84       executed with systemd.log_target=kmsg parameter, you must turn  on  the
85       domain_can_write_kmsg boolean. Disabled by default.
86
87       setsebool -P domain_can_write_kmsg 1
88
89
90
91       If you want to allow all domains to use other domains file descriptors,
92       you must turn on the domain_fd_use boolean. Enabled by default.
93
94       setsebool -P domain_fd_use 1
95
96
97
98       If you want to allow all domains to have the kernel load  modules,  you
99       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
100       default.
101
102       setsebool -P domain_kernel_load_modules 1
103
104
105
106       If you want to allow all domains to execute in fips_mode, you must turn
107       on the fips_mode boolean. Enabled by default.
108
109       setsebool -P fips_mode 1
110
111
112
113       If you want to enable reading of urandom for all domains, you must turn
114       on the global_ssp boolean. Disabled by default.
115
116       setsebool -P global_ssp 1
117

FILE CONTEXTS

121       SELinux requires files to have an extended attribute to define the file
122       type.
123
124       You can see the context of a file using the -Z option to ls
125
126       Policy  governs  the  access  confined  processes  have to these files.
127       SELinux loadkeys policy is very flexible allowing users to setup  their
128       loadkeys processes in as secure a method as possible.
129
130       The following file types are defined for loadkeys:
131
132
133
134       loadkeys_exec_t
135
136       - Set files with the loadkeys_exec_t type, if you want to transition an
137       executable to the loadkeys_t domain.
138
139
140       Paths:
141            /bin/unikeys, /bin/loadkeys, /usr/bin/unikeys, /usr/bin/loadkeys
142
143
144       Note: File context can be temporarily modified with the chcon  command.
145       If  you want to permanently change the file context you need to use the
146       semanage fcontext command.  This will modify the SELinux labeling data‐
147       base.  You will need to use restorecon to apply the labels.
148
149

COMMANDS

151       semanage  fcontext  can also be used to manipulate default file context
152       mappings.
153
154       semanage permissive can also be used to manipulate  whether  or  not  a
155       process type is permissive.
156
157       semanage  module can also be used to enable/disable/install/remove pol‐
158       icy modules.
159
160       semanage boolean can also be used to manipulate the booleans
161
162
163       system-config-selinux is a GUI tool available to customize SELinux pol‐
164       icy settings.
