6 NetworkManager_dispatcher_chronyc_selinux - Security Enhanced Linux
7 Policy for the NetworkManager_dispatcher_chronyc processes
8
10 Security-Enhanced Linux secures the NetworkManager_dispatcher_chronyc
11 processes via flexible mandatory access control.
12 The NetworkManager_dispatcher_chronyc processes execute with the Net‐
14 workManager_dispatcher_chronyc_t SELinux type. You can check if you
15 have these processes running by executing the ps command with the -Z
16 qualifier.
17 For example:
19 ps -eZ | grep NetworkManager_dispatcher_chronyc_t
21
25 The NetworkManager_dispatcher_chronyc_t SELinux type can be entered via
26 the NetworkManager_dispatcher_chronyc_script_t file type.
27 The default entrypoint paths for the NetworkManager_dis‐
29 patcher_chronyc_t domain are the following:
30 /etc/NetworkManager/dispatcher.d/20-chrony-dhcp, /usr/lib/NetworkMan‐
32 ager/dispatcher.d/20-chrony-dhcp, /etc/NetworkManager/dis‐
33 patcher.d/20-chrony-onoffline, /usr/lib/NetworkManager/dis‐
34 patcher.d/20-chrony-onoffline
35
37 SELinux defines process types (domains) for each process running on the
38 system
39 You can see the context of a process using the -Z option to ps
41 Policy governs the access confined processes have to files. SELinux
43 NetworkManager_dispatcher_chronyc policy is very flexible allowing
44 users to setup their NetworkManager_dispatcher_chronyc processes in as
45 secure a method as possible.
46 The following process types are defined for NetworkManager_dis‐
48 patcher_chronyc:
49 NetworkManager_dispatcher_chronyc_t
51 Note: semanage permissive -a NetworkManager_dispatcher_chronyc_t can be
53 used to make the process type NetworkManager_dispatcher_chronyc_t per‐
54 missive. SELinux does not deny access to permissive process types, but
55 the AVC (SELinux denials) messages are still generated.
56
59 SELinux policy is customizable based on least access required. Net‐
60 workManager_dispatcher_chronyc policy is extremely flexible and has
61 several booleans that allow you to manipulate the policy and run Net‐
62 workManager_dispatcher_chronyc with the tightest access possible.
63 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68 setsebool -P fips_mode 1
70
74 The SELinux process type NetworkManager_dispatcher_chronyc_t can manage
75 files labeled with the following file types. The paths listed are the
76 default paths for these file types. Note the processes UID still need
77 to have DAC permissions.
78 chronyd_var_run_t
80 /var/run/chrony(/.*)?
82 /var/run/chronyd(/.*)?
83 /var/run/chrony-dhcp(/.*)?
84 /var/run/chrony-helper(/.*)?
85 /var/run/chronyd.pid
86 /var/run/chronyd.sock
87
90 SELinux requires files to have an extended attribute to define the file
91 type.
92 You can see the context of a file using the -Z option to ls
94 Policy governs the access confined processes have to these files.
96 SELinux NetworkManager_dispatcher_chronyc policy is very flexible al‐
97 lowing users to setup their NetworkManager_dispatcher_chronyc processes
98 in as secure a method as possible.
99 STANDARD FILE CONTEXT
101 SELinux defines the file context types for the NetworkManager_dis‐
103 patcher_chronyc, if you wanted to store files with these types in a
104 different paths, you need to execute the semanage command to specify
105 alternate labeling and then use restorecon to put the labels on disk.
106 semanage fcontext -a -t NetworkManager_dispatcher_chronyc_script_t
108 '/srv/NetworkManager_dispatcher_chronyc/content(/.*)?'
109 restorecon -R -v /srv/myNetworkManager_dispatcher_chronyc_content
110 Note: SELinux often uses regular expressions to specify labels that
112 match multiple files.
113 The following file types are defined for NetworkManager_dis‐
115 patcher_chronyc:
116 NetworkManager_dispatcher_chronyc_script_t
120 - Set files with the NetworkManager_dispatcher_chronyc_script_t type,
122 if you want to treat the files as NetworkManager dispatcher chronyc
123 script data.
124 Paths:
127 /etc/NetworkManager/dispatcher.d/20-chrony-dhcp, /usr/lib/Network‐
128 Manager/dispatcher.d/20-chrony-dhcp, /etc/NetworkManager/dis‐
129 patcher.d/20-chrony-onoffline, /usr/lib/NetworkManager/dis‐
130 patcher.d/20-chrony-onoffline
131 Note: File context can be temporarily modified with the chcon command.
134 If you want to permanently change the file context you need to use the
135 semanage fcontext command. This will modify the SELinux labeling data‐
136 base. You will need to use restorecon to apply the labels.
137
140 semanage fcontext can also be used to manipulate default file context
141 mappings.
142 semanage permissive can also be used to manipulate whether or not a
144 process type is permissive.
145 semanage module can also be used to enable/disable/install/remove pol‐
147 icy modules.
148 semanage boolean can also be used to manipulate the booleans
150 system-config-selinux is a GUI tool available to customize SELinux pol‐
153 icy settings.
