6 rdisc_selinux - Security Enhanced Linux Policy for the rdisc processes
7
9 Security-Enhanced Linux secures the rdisc processes via flexible manda‐
10 tory access control.
11 The rdisc processes execute with the rdisc_t SELinux type. You can
13 check if you have these processes running by executing the ps command
14 with the -Z qualifier.
15 For example:
17 ps -eZ | grep rdisc_t
19
23 The rdisc_t SELinux type can be entered via the rdisc_exec_t file type.
24 The default entrypoint paths for the rdisc_t domain are the following:
26 /sbin/rdisc
28
30 SELinux defines process types (domains) for each process running on the
31 system
32 You can see the context of a process using the -Z option to ps
34 Policy governs the access confined processes have to files. SELinux
36 rdisc policy is very flexible allowing users to setup their rdisc pro‐
37 cesses in as secure a method as possible.
38 The following process types are defined for rdisc:
40 rdisc_t
42 Note: semanage permissive -a rdisc_t can be used to make the process
44 type rdisc_t permissive. SELinux does not deny access to permissive
45 process types, but the AVC (SELinux denials) messages are still gener‐
46 ated.
47
50 SELinux policy is customizable based on least access required. rdisc
51 policy is extremely flexible and has several booleans that allow you to
52 manipulate the policy and run rdisc with the tightest access possible.
53 If you want to allow all daemons to write corefiles to /, you must turn
57 on the allow_daemons_dump_core boolean. Disabled by default.
58 setsebool -P allow_daemons_dump_core 1
60 If you want to allow all daemons to use tcp wrappers, you must turn on
64 the allow_daemons_use_tcp_wrapper boolean. Disabled by default.
65 setsebool -P allow_daemons_use_tcp_wrapper 1
67 If you want to allow all daemons the ability to read/write terminals,
71 you must turn on the allow_daemons_use_tty boolean. Disabled by
72 default.
73 setsebool -P allow_daemons_use_tty 1
75 If you want to allow all domains to use other domains file descriptors,
79 you must turn on the allow_domain_fd_use boolean. Enabled by default.
80 setsebool -P allow_domain_fd_use 1
82 If you want to allow sysadm to debug or ptrace all processes, you must
86 turn on the allow_ptrace boolean. Disabled by default.
87 setsebool -P allow_ptrace 1
89 If you want to enable cluster mode for daemons, you must turn on the
93 daemons_enable_cluster_mode boolean. Disabled by default.
94 setsebool -P daemons_enable_cluster_mode 1
96 If you want to allow all domains to have the kernel load modules, you
100 must turn on the domain_kernel_load_modules boolean. Disabled by
101 default.
102 setsebool -P domain_kernel_load_modules 1
104 If you want to allow all domains to execute in fips_mode, you must turn
108 on the fips_mode boolean. Enabled by default.
109 setsebool -P fips_mode 1
111 If you want to enable reading of urandom for all domains, you must turn
115 on the global_ssp boolean. Disabled by default.
116 setsebool -P global_ssp 1
118 If you want to enable support for upstart as the init program, you must
122 turn on the init_upstart boolean. Enabled by default.
123 setsebool -P init_upstart 1
125
129 The SELinux process type rdisc_t can manage files labeled with the fol‐
130 lowing file types. The paths listed are the default paths for these
131 file types. Note the processes UID still need to have DAC permissions.

192 SELinux requires files to have an extended attribute to define the file
193 type.
194 You can see the context of a file using the -Z option to ls
196 Policy governs the access confined processes have to these files.
198 SELinux rdisc policy is very flexible allowing users to setup their
199 rdisc processes in as secure a method as possible.
200 The following file types are defined for rdisc:
202 rdisc_exec_t
206 - Set files with the rdisc_exec_t type, if you want to transition an
208 executable to the rdisc_t domain.
209 Note: File context can be temporarily modified with the chcon command.
213 If you want to permanently change the file context you need to use the
214 semanage fcontext command. This will modify the SELinux labeling data‐
215 base. You will need to use restorecon to apply the labels.
216
219 semanage fcontext can also be used to manipulate default file context
220 mappings.
221 semanage permissive can also be used to manipulate whether or not a
223 process type is permissive.
224 semanage module can also be used to enable/disable/install/remove pol‐
226 icy modules.
227 semanage boolean can also be used to manipulate the booleans
229 system-config-selinux is a GUI tool available to customize SELinux pol‐
232 icy settings.
