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 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
93
94
95
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
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
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.
