NAME

6       chronyc_selinux  -  Security Enhanced Linux Policy for the chronyc pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  chronyc  processes  via  flexible
11       mandatory access control.
12
13       The  chronyc processes execute with the chronyc_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 chronyc_t
20
21
22

ENTRYPOINTS

24       The  chronyc_t  SELinux type can be entered via the chronyc_exec_t file
25       type.
26
27       The default entrypoint paths for the chronyc_t domain are  the  follow‐
28       ing:
29
30       /usr/bin/chronyc
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       chronyc  policy  is very flexible allowing users to setup their chronyc
40       processes in as secure a method as possible.
41
42       The following process types are defined for chronyc:
43
44       chronyc_t
45
46       Note: semanage permissive -a chronyc_t can be used to make the  process
47       type  chronyc_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.  chronyc
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run chronyc 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
64
65
66
67       If  you  want  to  allow  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1
71

73

MANAGED FILES

75       The SELinux process type chronyc_t can manage files  labeled  with  the
76       following file types.  The paths listed are the default paths for these
77       file types.  Note the processes UID still need to have DAC permissions.

79       non_security_file_type

82

FILE CONTEXTS

84       SELinux requires files to have an extended attribute to define the file
85       type.
86
87       You can see the context of a file using the -Z option to ls
88
89       Policy  governs  the  access  confined  processes  have to these files.
90       SELinux chronyc policy is very flexible allowing users to  setup  their
91       chronyc processes in as secure a method as possible.
92
93       The following file types are defined for chronyc:
94
95
96
97       chronyc_exec_t
98
99       -  Set files with the chronyc_exec_t type, if you want to transition an
100       executable to the chronyc_t domain.
101
102
103
104       Note: File context can be temporarily modified with the chcon  command.
105       If  you want to permanently change the file context you need to use the
106       semanage fcontext command.  This will modify the SELinux labeling data‐
107       base.  You will need to use restorecon to apply the labels.
108
109

COMMANDS

111       semanage  fcontext  can also be used to manipulate default file context
112       mappings.
113
114       semanage permissive can also be used to manipulate  whether  or  not  a
115       process type is permissive.
116
117       semanage  module can also be used to enable/disable/install/remove pol‐
118       icy modules.
119
120       semanage boolean can also be used to manipulate the booleans
121
122
123       system-config-selinux is a GUI tool available to customize SELinux pol‐
124       icy settings.
