NAME

6       hwclock_selinux  -  Security Enhanced Linux Policy for the hwclock pro‐
7       cesses
8

DESCRIPTION

10       Security-Enhanced Linux secures  the  hwclock  processes  via  flexible
11       mandatory access control.
12
13       The  hwclock processes execute with the hwclock_t SELinux type. You can
14       check if you have these processes running by executing the  ps  command
15       with the -Z qualifier.
16
17       For example:
18
19       ps -eZ | grep hwclock_t
20
21
22

ENTRYPOINTS

24       The  hwclock_t  SELinux type can be entered via the hwclock_exec_t file
25       type.
26
27       The default entrypoint paths for the hwclock_t domain are  the  follow‐
28       ing:
29
30       /sbin/hwclock, /usr/sbin/hwclock
31

PROCESS TYPES

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       hwclock  policy  is very flexible allowing users to setup their hwclock
40       processes in as secure a method as possible.
41
42       The following process types are defined for hwclock:
43
44       hwclock_t
45
46       Note: semanage permissive -a hwclock_t can be used to make the  process
47       type  hwclock_t  permissive. SELinux does not deny access to permissive
48       process types, but the AVC (SELinux denials) messages are still  gener‐
49       ated.

51

BOOLEANS

53       SELinux policy is customizable based on least access required.  hwclock
54       policy is extremely flexible and has several booleans that allow you to
55       manipulate  the  policy and run hwclock with the tightest access possi‐
56       ble.
57
58
59
60       If you want to allow all domains to execute in fips_mode, you must turn
61       on the fips_mode boolean. Enabled by default.
62
63       setsebool -P fips_mode 1
64
65
66
67       If  you  want  to  allow  system  to run with NIS, you must turn on the
68       nis_enabled boolean. Disabled by default.
69
70       setsebool -P nis_enabled 1
71
72
73

MANAGED FILES

75       The SELinux process type hwclock_t can manage files  labeled  with  the
76       following file types.  The paths listed are the default paths for these
77       file types.  Note the processes UID still need to have DAC permissions.
78
79       adjtime_t
80
81            /etc/adjtime
82
83       krb5_host_rcache_t
84
85            /var/tmp/krb5_0.rcache2
86            /var/cache/krb5rcache(/.*)?
87            /var/tmp/nfs_0
88            /var/tmp/DNS_25
89            /var/tmp/host_0
90            /var/tmp/imap_0
91            /var/tmp/HTTP_23
92            /var/tmp/HTTP_48
93            /var/tmp/ldap_55
94            /var/tmp/ldap_487
95            /var/tmp/ldapmap1_0

FILE CONTEXTS

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 hwclock policy is very flexible allowing users to  setup  their
106       hwclock processes in as secure a method as possible.
107
108       STANDARD FILE CONTEXT
109
110       SELinux  defines  the file context types for the hwclock, if you wanted
111       to store files with these types in a different paths, you need to  exe‐
112       cute  the  semanage  command to specify alternate labeling and then use
113       restorecon to put the labels on disk.
114
115       semanage fcontext -a -t hwclock_exec_t '/srv/hwclock/content(/.*)?'
116       restorecon -R -v /srv/myhwclock_content
117
118       Note: SELinux often uses regular expressions  to  specify  labels  that
119       match multiple files.
120
121       The following file types are defined for hwclock:
122
123
124
125       hwclock_exec_t
126
127       -  Set files with the hwclock_exec_t type, if you want to transition an
128       executable to the hwclock_t domain.
129
130
131       Paths:
132            /sbin/hwclock, /usr/sbin/hwclock
133
134
135       Note: File context can be temporarily modified with the chcon  command.
136       If  you want to permanently change the file context you need to use the
137       semanage fcontext command.  This will modify the SELinux labeling data‐
138       base.  You will need to use restorecon to apply the labels.

140

COMMANDS

142       semanage  fcontext  can also be used to manipulate default file context
143       mappings.
144
145       semanage permissive can also be used to manipulate  whether  or  not  a
146       process type is permissive.
147
148       semanage  module can also be used to enable/disable/install/remove pol‐
149       icy modules.
150
151       semanage boolean can also be used to manipulate the booleans
152
153
154       system-config-selinux is a GUI tool available to customize SELinux pol‐
155       icy settings.
