NAME

6       prelink_cron_system_selinux  -  Security  Enhanced Linux Policy for the
7       prelink_cron_system processes
8

DESCRIPTION

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

ENTRYPOINTS

24       The  prelink_cron_system_t  SELinux  type  can  be entered via the pre‐
25       link_cron_system_exec_t file type.
26
27       The default entrypoint paths for the prelink_cron_system_t  domain  are
28       the following:
29
30       /etc/cron.daily/prelink
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       prelink_cron_system  policy  is  very  flexible allowing users to setup
40       their prelink_cron_system processes in as secure a method as possible.
41
42       The following process types are defined for prelink_cron_system:
43
44       prelink_cron_system_t
45
46       Note: semanage permissive -a prelink_cron_system_t can be used to  make
47       the  process  type  prelink_cron_system_t  permissive. SELinux does not
48       deny access to permissive process types, but the AVC (SELinux  denials)
49       messages are still generated.

51

BOOLEANS

53       SELinux  policy  is  customizable based on least access required.  pre‐
54       link_cron_system policy is extremely flexible and has several  booleans
55       that  allow  you  to  manipulate the policy and run prelink_cron_system
56       with the tightest 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

MANAGED FILES

97       The SELinux process type prelink_cron_system_t can manage files labeled
98       with  the following file types.  The paths listed are the default paths
99       for these file types.  Note the processes UID still need  to  have  DAC
100       permissions.
101
102       prelink_log_t
103
104            /var/log/prelink(/.*)?
105            /var/log/prelink.log.*
106
107       prelink_var_lib_t
108
109            /var/lib/prelink(/.*)?
110            /var/lib/misc/prelink.*
111
112       systemd_passwd_var_run_t
113
114            /var/run/systemd/ask-password(/.*)?
115            /var/run/systemd/ask-password-block(/.*)?
116
117

FILE CONTEXTS

119       SELinux requires files to have an extended attribute to define the file
120       type.
121
122       You can see the context of a file using the -Z option to ls
123
124       Policy governs the access  confined  processes  have  to  these  files.
125       SELinux  prelink_cron_system  policy is very flexible allowing users to
126       setup their prelink_cron_system processes in as secure a method as pos‐
127       sible.
128
129       The following file types are defined for prelink_cron_system:
130
131
132
133       prelink_cron_system_exec_t
134
135       -  Set  files  with the prelink_cron_system_exec_t type, if you want to
136       transition an executable to the prelink_cron_system_t domain.
137
138
139
140       Note: File context can be temporarily modified with the chcon  command.
141       If  you want to permanently change the file context you need to use the
142       semanage fcontext command.  This will modify the SELinux labeling data‐
143       base.  You will need to use restorecon to apply the labels.
144
145

COMMANDS

147       semanage  fcontext  can also be used to manipulate default file context
148       mappings.
149
150       semanage permissive can also be used to manipulate  whether  or  not  a
151       process type is permissive.
152
153       semanage  module can also be used to enable/disable/install/remove pol‐
154       icy modules.
155
156       semanage boolean can also be used to manipulate the booleans
157
158
159       system-config-selinux is a GUI tool available to customize SELinux pol‐
160       icy settings.
