6 usernetctl_selinux - Security Enhanced Linux Policy for the usernetctl
7 processes
8
10 Security-Enhanced Linux secures the usernetctl processes via flexible
11 mandatory access control.
12
13 The usernetctl processes execute with the usernetctl_t SELinux type.
14 You can check if you have these processes running by executing the ps
15 command with the -Z qualifier.
16
17 For example:
18
19 ps -eZ | grep usernetctl_t
20
21
22
24 The usernetctl_t SELinux type can be entered via the usernetctl_exec_t
25 file type.
26
27 The default entrypoint paths for the usernetctl_t domain are the fol‐
28 lowing:
29
30 /usr/sbin/usernetctl
31
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 usernetctl policy is very flexible allowing users to setup their user‐
40 netctl processes in as secure a method as possible.
41
42 The following process types are defined for usernetctl:
43
44 usernetctl_t
45
46 Note: semanage permissive -a usernetctl_t can be used to make the
47 process type usernetctl_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
51
53 SELinux policy is customizable based on least access required. user‐
54 netctl policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run usernetctl with the tightest
56 access possible.
57
58
59
60 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63
64 setsebool -P authlogin_nsswitch_use_ldap 1
65
66
67
68 If you want to allow all domains to execute in fips_mode, you must turn
69 on the fips_mode boolean. Enabled by default.
70
71 setsebool -P fips_mode 1
72
73
74
75 If you want to allow confined applications to run with kerberos, you
76 must turn on the kerberos_enabled boolean. Enabled by default.
77
78 setsebool -P kerberos_enabled 1
79
80
81
82 If you want to allow system to run with NIS, you must turn on the
83 nis_enabled boolean. Disabled by default.
84
85 setsebool -P nis_enabled 1
86
87
88
89 If you want to allow confined applications to use nscd shared memory,
90 you must turn on the nscd_use_shm boolean. Disabled by default.
91
92 setsebool -P nscd_use_shm 1
93
94
95
97 SELinux requires files to have an extended attribute to define the file
98 type.
99
100 You can see the context of a file using the -Z option to ls
101
102 Policy governs the access confined processes have to these files.
103 SELinux usernetctl policy is very flexible allowing users to setup
104 their usernetctl processes in as secure a method as possible.
105
106 The following file types are defined for usernetctl:
107
108
109
110 usernetctl_exec_t
111
112 - Set files with the usernetctl_exec_t type, if you want to transition
113 an executable to the usernetctl_t domain.
114
115
116
117 Note: File context can be temporarily modified with the chcon command.
118 If you want to permanently change the file context you need to use the
119 semanage fcontext command. This will modify the SELinux labeling data‐
120 base. You will need to use restorecon to apply the labels.
121
122
124 semanage fcontext can also be used to manipulate default file context
125 mappings.
126
127 semanage permissive can also be used to manipulate whether or not a
128 process type is permissive.
129
130 semanage module can also be used to enable/disable/install/remove pol‐
131 icy modules.
132
133 semanage boolean can also be used to manipulate the booleans
134
135
136 system-config-selinux is a GUI tool available to customize SELinux pol‐
137 icy settings.
