NAME

6       vlock_selinux - Security Enhanced Linux Policy for the vlock processes
7

DESCRIPTION

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

21

ENTRYPOINTS

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

PROCESS TYPES

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.

BOOLEANS

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 users to resolve user passwd entries directly from
57       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
58       gin_nsswitch_use_ldap boolean. Disabled by default.
59
60       setsebool -P authlogin_nsswitch_use_ldap 1
61
62
63
64       If you want to allow all domains to execute in fips_mode, you must turn
65       on the fips_mode boolean. Enabled by default.
66
67       setsebool -P fips_mode 1
68
69
70
71       If  you  want  to allow confined applications to run with kerberos, you
72       must turn on the kerberos_enabled boolean. Disabled by default.
73
74       setsebool -P kerberos_enabled 1
75
76
77
78       If you want to allow system to run with  NIS,  you  must  turn  on  the
79       nis_enabled boolean. Disabled by default.
80
81       setsebool -P nis_enabled 1
82
83
84
85       If  you  want to allow confined applications to use nscd shared memory,
86       you must turn on the nscd_use_shm boolean. Disabled by default.
87
88       setsebool -P nscd_use_shm 1

MANAGED FILES

93       The SELinux process type vlock_t can manage files labeled with the fol‐
94       lowing  file  types.   The paths listed are the default paths for these
95       file types.  Note the processes UID still need to have DAC permissions.
96
97       faillog_t
98
99            /var/log/btmp.*
100            /var/log/faillog.*
101            /var/log/tallylog.*
102            /var/run/faillock(/.*)?
103
104       krb5_host_rcache_t
105
106            /var/cache/krb5rcache(/.*)?
107            /var/tmp/nfs_0
108            /var/tmp/DNS_25
109            /var/tmp/host_0
110            /var/tmp/imap_0
111            /var/tmp/HTTP_23
112            /var/tmp/HTTP_48
113            /var/tmp/ldap_55
114            /var/tmp/ldap_487
115            /var/tmp/ldapmap1_0
116
117       lastlog_t
118
119            /var/log/lastlog.*

FILE CONTEXTS

127       SELinux requires files to have an extended attribute to define the file
128       type.
129
130       You can see the context of a file using the -Z option to ls
131
132       Policy  governs  the  access  confined  processes  have to these files.
133       SELinux vlock policy is very flexible allowing  users  to  setup  their
134       vlock processes in as secure a method as possible.
135
136       The following file types are defined for vlock:
137
138
139
140       vlock_exec_t
141
142       -  Set  files  with the vlock_exec_t type, if you want to transition an
143       executable to the vlock_t domain.
144
145
146       Paths:
147            /usr/bin/vlock, /usr/sbin/vlock-main
148
149
150       Note: File context can be temporarily modified with the chcon  command.
151       If  you want to permanently change the file context you need to use the
152       semanage fcontext command.  This will modify the SELinux labeling data‐
153       base.  You will need to use restorecon to apply the labels.
154
155

COMMANDS

157       semanage  fcontext  can also be used to manipulate default file context
158       mappings.
159
160       semanage permissive can also be used to manipulate  whether  or  not  a
161       process type is permissive.
162
163       semanage  module can also be used to enable/disable/install/remove pol‐
164       icy modules.
165
166       semanage boolean can also be used to manipulate the booleans
167
168
169       system-config-selinux is a GUI tool available to customize SELinux pol‐
170       icy settings.
