6 vlock_selinux - Security Enhanced Linux Policy for the vlock processes
7
9 Security-Enhanced Linux secures the vlock processes via flexible manda‐
10 tory access control.
11
12 The vlock processes execute with the vlock_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15
16 For example:
17
18 ps -eZ | grep vlock_t
19
20
21
23 The vlock_t SELinux type can be entered via the vlock_exec_t file type.
24
25 The default entrypoint paths for the vlock_t domain are the following:
26
27 /usr/bin/vlock, /usr/sbin/vlock-main
28
30 SELinux defines process types (domains) for each process running on the
31 system
32
33 You can see the context of a process using the -Z option to ps
34
35 Policy governs the access confined processes have to files. SELinux
36 vlock policy is very flexible allowing users to setup their vlock pro‐
37 cesses in as secure a method as possible.
38
39 The following process types are defined for vlock:
40
41 vlock_t
42
43 Note: semanage permissive -a vlock_t can be used to make the process
44 type vlock_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
48
50 SELinux policy is customizable based on least access required. vlock
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run vlock with the tightest access possible.
53
54
55
56 If you want to allow all domains to execute in fips_mode, you must turn
57 on the fips_mode boolean. Enabled by default.
58
59 setsebool -P fips_mode 1
60
61
62
63 If you want to allow confined applications to run with kerberos, you
64 must turn on the kerberos_enabled boolean. Disabled by default.
65
66 setsebool -P kerberos_enabled 1
67
68
69
70 If you want to allow system to run with NIS, you must turn on the
71 nis_enabled boolean. Disabled by default.
72
73 setsebool -P nis_enabled 1
74
75
76
78 The SELinux process type vlock_t can manage files labeled with the fol‐
79 lowing file types. The paths listed are the default paths for these
80 file types. Note the processes UID still need to have DAC permissions.
81
82 faillog_t
83
84 /var/log/btmp.*
85 /var/log/faillog.*
86 /var/log/tallylog.*
87 /var/run/faillock(/.*)?

89 lastlog_t
90
91 /var/log/lastlog.*

99 SELinux requires files to have an extended attribute to define the file
100 type.
101
102 You can see the context of a file using the -Z option to ls
103
104 Policy governs the access confined processes have to these files.
105 SELinux vlock policy is very flexible allowing users to setup their
106 vlock processes in as secure a method as possible.
107
108 The following file types are defined for vlock:
109
110
111
112 vlock_exec_t
113
114 - Set files with the vlock_exec_t type, if you want to transition an
115 executable to the vlock_t domain.
116
117
118 Paths:
119 /usr/bin/vlock, /usr/sbin/vlock-main
120
121
122 Note: File context can be temporarily modified with the chcon command.
123 If you want to permanently change the file context you need to use the
124 semanage fcontext command. This will modify the SELinux labeling data‐
125 base. You will need to use restorecon to apply the labels.
126
127
129 semanage fcontext can also be used to manipulate default file context
130 mappings.
131
132 semanage permissive can also be used to manipulate whether or not a
133 process type is permissive.
134
135 semanage module can also be used to enable/disable/install/remove pol‐
136 icy modules.
137
138 semanage boolean can also be used to manipulate the booleans
139
140
141 system-config-selinux is a GUI tool available to customize SELinux pol‐
142 icy settings.
