6 locate_selinux - Security Enhanced Linux Policy for the locate pro‐
7 cesses
8
10 Security-Enhanced Linux secures the locate processes via flexible
11 mandatory access control.
12
13 The locate processes execute with the locate_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 locate_t
20
21
22
24 The locate_t SELinux type can be entered via the locate_exec_t file
25 type.
26
27 The default entrypoint paths for the locate_t domain are the following:
28
29 /etc/cron.daily/[sm]locate, /usr/bin/updatedb.*
30
32 SELinux defines process types (domains) for each process running on the
33 system
34
35 You can see the context of a process using the -Z option to ps
36
37 Policy governs the access confined processes have to files. SELinux
38 locate policy is very flexible allowing users to setup their locate
39 processes in as secure a method as possible.
40
41 The following process types are defined for locate:
42
43 locate_t
44
45 Note: semanage permissive -a locate_t can be used to make the process
46 type locate_t permissive. SELinux does not deny access to permissive
47 process types, but the AVC (SELinux denials) messages are still gener‐
48 ated.
49
50
52 SELinux policy is customizable based on least access required. locate
53 policy is extremely flexible and has several booleans that allow you to
54 manipulate the policy and run locate with the tightest access possible.
55
56
57
58 If you want to allow users to resolve user passwd entries directly from
59 ldap rather then using a sssd server, you must turn on the authlo‐
60 gin_nsswitch_use_ldap boolean. Disabled by default.
61
62 setsebool -P authlogin_nsswitch_use_ldap 1
63
64
65
66 If you want to allow all domains to execute in fips_mode, you must turn
67 on the fips_mode boolean. Enabled by default.
68
69 setsebool -P fips_mode 1
70
71
72
73 If you want to allow confined applications to run with kerberos, you
74 must turn on the kerberos_enabled boolean. Enabled by default.
75
76 setsebool -P kerberos_enabled 1
77
78
79
80 If you want to allow system to run with NIS, you must turn on the
81 nis_enabled boolean. Disabled by default.
82
83 setsebool -P nis_enabled 1
84
85
86
87 If you want to allow confined applications to use nscd shared memory,
88 you must turn on the nscd_use_shm boolean. Disabled by default.
89
90 setsebool -P nscd_use_shm 1
91
92
93
95 The SELinux process type locate_t can manage files labeled with the
96 following file types. The paths listed are the default paths for these
97 file types. Note the processes UID still need to have DAC permissions.
98
99 locate_var_lib_t
100
101 /var/lib/[sm]locate(/.*)?
102
103 locate_var_run_t
104
105 /var/run/mlocate.daily.lock
106
107
109 SELinux requires files to have an extended attribute to define the file
110 type.
111
112 You can see the context of a file using the -Z option to ls
113
114 Policy governs the access confined processes have to these files.
115 SELinux locate policy is very flexible allowing users to setup their
116 locate processes in as secure a method as possible.
117
118 STANDARD FILE CONTEXT
119
120 SELinux defines the file context types for the locate, if you wanted to
121 store files with these types in a diffent paths, you need to execute
122 the semanage command to sepecify alternate labeling and then use
123 restorecon to put the labels on disk.
124
125 semanage fcontext -a -t locate_var_run_t '/srv/mylocate_content(/.*)?'
126 restorecon -R -v /srv/mylocate_content
127
128 Note: SELinux often uses regular expressions to specify labels that
129 match multiple files.
130
131 The following file types are defined for locate:
132
133
134
135 locate_exec_t
136
137 - Set files with the locate_exec_t type, if you want to transition an
138 executable to the locate_t domain.
139
140
141 Paths:
142 /etc/cron.daily/[sm]locate, /usr/bin/updatedb.*
143
144
145 locate_var_lib_t
146
147 - Set files with the locate_var_lib_t type, if you want to store the
148 locate files under the /var/lib directory.
149
150
151
152 locate_var_run_t
153
154 - Set files with the locate_var_run_t type, if you want to store the
155 locate files under the /run or /var/run directory.
156
157
158
159 Note: File context can be temporarily modified with the chcon command.
160 If you want to permanently change the file context you need to use the
161 semanage fcontext command. This will modify the SELinux labeling data‐
162 base. You will need to use restorecon to apply the labels.
163
164
166 semanage fcontext can also be used to manipulate default file context
167 mappings.
168
169 semanage permissive can also be used to manipulate whether or not a
170 process type is permissive.
171
172 semanage module can also be used to enable/disable/install/remove pol‐
173 icy modules.
174
175 semanage boolean can also be used to manipulate the booleans
176
177
178 system-config-selinux is a GUI tool available to customize SELinux pol‐
179 icy settings.
