6 prelink_cron_system_selinux - Security Enhanced Linux Policy for the
7 prelink_cron_system processes
8
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
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
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
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 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
75 The SELinux process type prelink_cron_system_t can manage files labeled
76 with the following file types. The paths listed are the default paths
77 for these file types. Note the processes UID still need to have DAC
78 permissions.

111 SELinux requires files to have an extended attribute to define the file
112 type.
113
114 You can see the context of a file using the -Z option to ls
115
116 Policy governs the access confined processes have to these files.
117 SELinux prelink_cron_system policy is very flexible allowing users to
118 setup their prelink_cron_system processes in as secure a method as pos‐
119 sible.
120
121 STANDARD FILE CONTEXT
122
123 SELinux defines the file context types for the prelink_cron_system, if
124 you wanted to store files with these types in a different paths, you
125 need to execute the semanage command to specify alternate labeling and
126 then use restorecon to put the labels on disk.
127
128 semanage fcontext -a -t prelink_cron_system_exec_t '/srv/pre‐
129 link_cron_system/content(/.*)?'
130 restorecon -R -v /srv/myprelink_cron_system_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 prelink_cron_system:
136
137
138
139 prelink_cron_system_exec_t
140
141 - Set files with the prelink_cron_system_exec_t type, if you want to
142 transition an executable to the prelink_cron_system_t domain.
143
144
145
146 Note: File context can be temporarily modified with the chcon command.
147 If you want to permanently change the file context you need to use the
148 semanage fcontext command. This will modify the SELinux labeling data‐
149 base. You will need to use restorecon to apply the labels.
150
151
153 semanage fcontext can also be used to manipulate default file context
154 mappings.
155
156 semanage permissive can also be used to manipulate whether or not a
157 process type is permissive.
158
159 semanage module can also be used to enable/disable/install/remove pol‐
160 icy modules.
161
162 semanage boolean can also be used to manipulate the booleans
163
164
165 system-config-selinux is a GUI tool available to customize SELinux pol‐
166 icy settings.
