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.
50
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

MANAGED FILES

68       The  SELinux  process  type chronyc_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       chronyd_keys_t
73
74            /etc/chrony.keys.*
75
76       chronyd_tmp_t
77
78
79       chronyd_tmpfs_t
80
81
82       chronyd_var_lib_t
83
84            /var/lib/chrony(/.*)?
85
86       chronyd_var_log_t
87
88            /var/log/chrony(/.*)?
89
90       chronyd_var_run_t
91
92            /var/run/chrony(/.*)?
93            /var/run/chronyd(/.*)?
94            /var/run/chrony-helper(/.*)?
95            /var/run/chronyd.pid
96            /var/run/chronyd.sock

FILE CONTEXTS

100       SELinux requires files to have an extended attribute to define the file
101       type.
102
103       You can see the context of a file using the -Z option to ls
104
105       Policy governs the access  confined  processes  have  to  these  files.
106       SELinux  chronyc  policy is very flexible allowing users to setup their
107       chronyc processes in as secure a method as possible.
108
109       The following file types are defined for chronyc:
110
111
112
113       chronyc_exec_t
114
115       - Set files with the chronyc_exec_t type, if you want to transition  an
116       executable to the chronyc_t domain.
117
118
119
120       Note:  File context can be temporarily modified with the chcon command.
121       If you want to permanently change the file context you need to use  the
122       semanage fcontext command.  This will modify the SELinux labeling data‐
123       base.  You will need to use restorecon to apply the labels.
124
125

COMMANDS

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