7 cesses

10 Security-Enhanced Linux secures the locate processes via flexible
11 mandatory access control.
12 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 For example:
18 ps -eZ | grep locate_t
20
24 The locate_t SELinux type can be entered via the locate_exec_t file
25 type.
26 The default entrypoint paths for the locate_t domain are the following:
28 /usr/bin/updatedb
30
32 SELinux defines process types (domains) for each process running on the
33 system
34 You can see the context of a process using the -Z option to ps
36 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 The following process types are defined for locate:
42 locate_t
44 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
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 If you want to allow all daemons the ability to read/write terminals,
59 you must turn on the allow_daemons_use_tty boolean. Disabled by
60 default.
61 setsebool -P allow_daemons_use_tty 1
63 If you want to allow all domains to use other domains file descriptors,
67 you must turn on the allow_domain_fd_use boolean. Enabled by default.
68 setsebool -P allow_domain_fd_use 1
70 If you want to allow confined applications to run with kerberos, you
74 must turn on the allow_kerberos boolean. Enabled by default.
75 setsebool -P allow_kerberos 1
77 If you want to allow sysadm to debug or ptrace all processes, you must
81 turn on the allow_ptrace boolean. Disabled by default.
82 setsebool -P allow_ptrace 1
84 If you want to allow system to run with NIS, you must turn on the
88 allow_ypbind boolean. Disabled by default.
89 setsebool -P allow_ypbind 1
91 If you want to allow all domains to have the kernel load modules, you
95 must turn on the domain_kernel_load_modules boolean. Disabled by
96 default.
97 setsebool -P domain_kernel_load_modules 1
99 If you want to allow all domains to execute in fips_mode, you must turn
103 on the fips_mode boolean. Enabled by default.
104 setsebool -P fips_mode 1
106 If you want to enable reading of urandom for all domains, you must turn
110 on the global_ssp boolean. Disabled by default.
111 setsebool -P global_ssp 1
113 If you want to allow confined applications to use nscd shared memory,
117 you must turn on the nscd_use_shm boolean. Enabled by default.
118 setsebool -P nscd_use_shm 1
120
124 The SELinux process type locate_t can manage files labeled with the
125 following file types. The paths listed are the default paths for these
126 file types. Note the processes UID still need to have DAC permissions.
127 initrc_tmp_t
129 locate_var_lib_t
132 /var/lib/[sm]locate(/.*)?
134 mnt_t
136 /mnt(/[^/]*)
138 /mnt(/[^/]*)?
139 /rhev(/[^/]*)?
140 /media(/[^/]*)
141 /media(/[^/]*)?
142 /etc/rhgb(/.*)?
143 /media/.hal-.*
144 /net
145 /afs
146 /rhev
147 /misc
148 tmp_t
150 /tmp
152 /usr/tmp
153 /var/tmp
154 /tmp-inst
155 /var/tmp-inst
156 /var/tmp/vi.recover
157
160 SELinux requires files to have an extended attribute to define the file
161 type.
162 You can see the context of a file using the -Z option to ls
164 Policy governs the access confined processes have to these files.
166 SELinux locate policy is very flexible allowing users to setup their
167 locate processes in as secure a method as possible.
168 STANDARD FILE CONTEXT
170 SELinux defines the file context types for the locate, if you wanted to
172 store files with these types in a diffent paths, you need to execute
173 the semanage command to sepecify alternate labeling and then use
174 restorecon to put the labels on disk.
175 semanage fcontext -a -t locate_var_lib_t '/srv/mylocate_content(/.*)?'
177 restorecon -R -v /srv/mylocate_content
178 Note: SELinux often uses regular expressions to specify labels that
180 match multiple files.
181 The following file types are defined for locate:
183 locate_exec_t
187 - Set files with the locate_exec_t type, if you want to transition an
189 executable to the locate_t domain.
190 locate_log_t
194 - Set files with the locate_log_t type, if you want to treat the data
196 as locate log data, usually stored under the /var/log directory.
197 locate_var_lib_t
201 - Set files with the locate_var_lib_t type, if you want to store the
203 locate files under the /var/lib directory.
204 Note: File context can be temporarily modified with the chcon command.
208 If you want to permanently change the file context you need to use the
209 semanage fcontext command. This will modify the SELinux labeling data‐
210 base. You will need to use restorecon to apply the labels.
211
214 semanage fcontext can also be used to manipulate default file context
215 mappings.
216 semanage permissive can also be used to manipulate whether or not a
218 process type is permissive.
219 semanage module can also be used to enable/disable/install/remove pol‐
221 icy modules.
222 semanage boolean can also be used to manipulate the booleans
224 system-config-selinux is a GUI tool available to customize SELinux pol‐
227 icy settings.
