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. Enabled 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.

113 SELinux requires files to have an extended attribute to define the file
114 type.
115
116 You can see the context of a file using the -Z option to ls
117
118 Policy governs the access confined processes have to these files.
119 SELinux vlock policy is very flexible allowing users to setup their
120 vlock processes in as secure a method as possible.
121
122 STANDARD FILE CONTEXT
123
124 SELinux defines the file context types for the vlock, if you wanted to
125 store files with these types in a different paths, you need to execute
126 the semanage command to specify alternate labeling and then use re‐
127 storecon to put the labels on disk.
128
129 semanage fcontext -a -t vlock_exec_t '/srv/vlock/content(/.*)?'
130 restorecon -R -v /srv/myvlock_content
131
132 Note: SELinux often uses regular expressions to specify labels that
133 match multiple files.
134
135 The following file types are defined for vlock:
136
137
138
139 vlock_exec_t
140
141 - Set files with the vlock_exec_t type, if you want to transition an
142 executable to the vlock_t domain.
143
144
145 Paths:
146 /usr/bin/vlock, /usr/sbin/vlock-main
147
148
149 Note: File context can be temporarily modified with the chcon command.
150 If you want to permanently change the file context you need to use the
151 semanage fcontext command. This will modify the SELinux labeling data‐
152 base. You will need to use restorecon to apply the labels.
153
154
156 semanage fcontext can also be used to manipulate default file context
157 mappings.
158
159 semanage permissive can also be used to manipulate whether or not a
160 process type is permissive.
161
162 semanage module can also be used to enable/disable/install/remove pol‐
163 icy modules.
164
165 semanage boolean can also be used to manipulate the booleans
166
167
168 system-config-selinux is a GUI tool available to customize SELinux pol‐
169 icy settings.
