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.
50
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 all domains to use other domains file descriptors,
61       you must turn on the allow_domain_fd_use boolean. Enabled by default.
62
63       setsebool -P allow_domain_fd_use 1
64
65
66
67       If  you want to allow sysadm to debug or ptrace all processes, you must
68       turn on the allow_ptrace boolean. Disabled by default.
69
70       setsebool -P allow_ptrace 1
71
72
73
74       If you want to allow all domains to have the kernel load  modules,  you
75       must  turn  on  the  domain_kernel_load_modules  boolean.  Disabled  by
76       default.
77
78       setsebool -P domain_kernel_load_modules 1
79
80
81
82       If you want to allow all domains to execute in fips_mode, you must turn
83       on the fips_mode boolean. Enabled by default.
84
85       setsebool -P fips_mode 1
86
87
88
89       If you want to enable reading of urandom for all domains, you must turn
90       on the global_ssp boolean. Disabled by default.
91
92       setsebool -P global_ssp 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       initrc_tmp_t
103
104
105       mnt_t
106
107            /mnt(/[^/]*)
108            /mnt(/[^/]*)?
109            /rhev(/[^/]*)?
110            /media(/[^/]*)
111            /media(/[^/]*)?
112            /etc/rhgb(/.*)?
113            /media/.hal-.*
114            /net
115            /afs
116            /rhev
117            /misc
118
119       prelink_log_t
120
121            /var/log/prelink(/.*)?
122            /var/log/prelink.log.*
123
124       prelink_var_lib_t
125
126            /var/lib/prelink(/.*)?
127            /var/lib/misc/prelink.*
128
129       tmp_t
130
131            /tmp
132            /usr/tmp
133            /var/tmp
134            /tmp-inst
135            /var/tmp-inst
136            /var/tmp/vi.recover

FILE CONTEXTS

140       SELinux requires files to have an extended attribute to define the file
141       type.
142
143       You can see the context of a file using the -Z option to ls
144
145       Policy governs the access  confined  processes  have  to  these  files.
146       SELinux  prelink_cron_system  policy is very flexible allowing users to
147       setup their prelink_cron_system processes in as secure a method as pos‐
148       sible.
149
150       The following file types are defined for prelink_cron_system:
151
152
153
154       prelink_cron_system_exec_t
155
156       -  Set  files  with the prelink_cron_system_exec_t type, if you want to
157       transition an executable to the prelink_cron_system_t domain.
158
159
160
161       Note: File context can be temporarily modified with the chcon  command.
162       If  you want to permanently change the file context you need to use the
163       semanage fcontext command.  This will modify the SELinux labeling data‐
164       base.  You will need to use restorecon to apply the labels.
165
166

COMMANDS

168       semanage  fcontext  can also be used to manipulate default file context
169       mappings.
170
171       semanage permissive can also be used to manipulate  whether  or  not  a
172       process type is permissive.
173
174       semanage  module can also be used to enable/disable/install/remove pol‐
175       icy modules.
176
177       semanage boolean can also be used to manipulate the booleans
178
179
180       system-config-selinux is a GUI tool available to customize SELinux pol‐
181       icy settings.
