6 netlogond_selinux - Security Enhanced Linux Policy for the netlogond
7 processes
8
10 Security-Enhanced Linux secures the netlogond processes via flexible
11 mandatory access control.
12 The netlogond processes execute with the netlogond_t SELinux type. You
14 can check if you have these processes running by executing the ps com‐
15 mand with the -Z qualifier.
16 For example:
18 ps -eZ | grep netlogond_t
20
24 The netlogond_t SELinux type can be entered via the netlogond_exec_t
25 file type.
26 The default entrypoint paths for the netlogond_t domain are the follow‐
28 ing:
29 /usr/sbin/netlogond
31
33 SELinux defines process types (domains) for each process running on the
34 system
35 You can see the context of a process using the -Z option to ps
37 Policy governs the access confined processes have to files. SELinux
39 netlogond policy is very flexible allowing users to setup their netlo‐
40 gond processes in as secure a method as possible.
41 The following process types are defined for netlogond:
43 netlogond_t
45 Note: semanage permissive -a netlogond_t can be used to make the
47 process type netlogond_t permissive. SELinux does not deny access to
48 permissive process types, but the AVC (SELinux denials) messages are
49 still generated.
50
53 SELinux policy is customizable based on least access required. netlo‐
54 gond policy is extremely flexible and has several booleans that allow
55 you to manipulate the policy and run netlogond with the tightest access
56 possible.
57 If you want to allow all daemons to write corefiles to /, you must turn
61 on the allow_daemons_dump_core boolean. Disabled by default.

97 daemons_enable_cluster_mode boolean. Disabled by default.

100 If you want to allow all domains to have the kernel load modules, you
104 must turn on the domain_kernel_load_modules boolean. Disabled by
105 default.
106 setsebool -P domain_kernel_load_modules 1
108 If you want to allow all domains to execute in fips_mode, you must turn
112 on the fips_mode boolean. Enabled by default.
113 setsebool -P fips_mode 1
115 If you want to enable reading of urandom for all domains, you must turn
119 on the global_ssp boolean. Disabled by default.
120 setsebool -P global_ssp 1
122 If you want to enable support for upstart as the init program, you must
126 turn on the init_upstart boolean. Enabled by default.
127 setsebool -P init_upstart 1

133 The SELinux process type netlogond_t can manage files labeled with the
134 following file types. The paths listed are the default paths for these
135 file types. Note the processes UID still need to have DAC permissions.

209 SELinux requires files to have an extended attribute to define the file
210 type.
211 You can see the context of a file using the -Z option to ls
213 Policy governs the access confined processes have to these files.
215 SELinux netlogond policy is very flexible allowing users to setup their
216 netlogond processes in as secure a method as possible.
217 STANDARD FILE CONTEXT
219 SELinux defines the file context types for the netlogond, if you wanted
221 to store files with these types in a diffent paths, you need to execute
222 the semanage command to sepecify alternate labeling and then use
223 restorecon to put the labels on disk.
224 semanage fcontext -a -t netlogond_var_socket_t '/srv/mynetlogond_con‐
226 tent(/.*)?'
227 restorecon -R -v /srv/mynetlogond_content
228 Note: SELinux often uses regular expressions to specify labels that
230 match multiple files.
231 The following file types are defined for netlogond:
233 netlogond_exec_t
237 - Set files with the netlogond_exec_t type, if you want to transition
239 an executable to the netlogond_t domain.
240 netlogond_var_lib_t
244 - Set files with the netlogond_var_lib_t type, if you want to store the
246 netlogond files under the /var/lib directory.
247 Paths:
250 /var/lib/likewise-open/krb5-affinity.conf, /var/lib/likewise-
251 open/LWNetsd.err
252 netlogond_var_run_t
255 - Set files with the netlogond_var_run_t type, if you want to store the
257 netlogond files under the /run or /var/run directory.
258 netlogond_var_socket_t
262 - Set files with the netlogond_var_socket_t type, if you want to treat
264 the files as netlogond var socket data.
265 Note: File context can be temporarily modified with the chcon command.
269 If you want to permanently change the file context you need to use the
270 semanage fcontext command. This will modify the SELinux labeling data‐
271 base. You will need to use restorecon to apply the labels.
272
275 semanage fcontext can also be used to manipulate default file context
276 mappings.
277 semanage permissive can also be used to manipulate whether or not a
279 process type is permissive.
280 semanage module can also be used to enable/disable/install/remove pol‐
282 icy modules.
283 semanage boolean can also be used to manipulate the booleans
285 system-config-selinux is a GUI tool available to customize SELinux pol‐
288 icy settings.
