6 newrole_selinux - Security Enhanced Linux Policy for the newrole pro‐
7 cesses
8
10 Security-Enhanced Linux secures the newrole processes via flexible
11 mandatory access control.
12 The newrole processes execute with the newrole_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 newrole_t
20
24 The newrole_t SELinux type can be entered via the newrole_exec_t file
25 type.
26 The default entrypoint paths for the newrole_t domain are the follow‐
28 ing:
29 /usr/bin/newrole
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 newrole policy is very flexible allowing users to setup their newrole
40 processes in as secure a method as possible.
41 The following process types are defined for newrole:
43 newrole_t
45 Note: semanage permissive -a newrole_t can be used to make the process
47 type newrole_t permissive. SELinux does not deny access to permissive
48 process types, but the AVC (SELinux denials) messages are still gener‐
49 ated.
50
53 SELinux policy is customizable based on least access required. newrole
54 policy is extremely flexible and has several booleans that allow you to
55 manipulate the policy and run newrole with the tightest access possi‐
56 ble.
57 If you want to allow all domains to use other domains file descriptors,
61 you must turn on the allow_domain_fd_use boolean. Enabled by default.
62 setsebool -P allow_domain_fd_use 1
64 If you want to allow confined applications to run with kerberos, you
68 must turn on the allow_kerberos boolean. Enabled by default.
69 setsebool -P allow_kerberos 1
71 If you want to enable polyinstantiated directory support, you must turn
75 on the allow_polyinstantiation boolean. Enabled by default.
76 setsebool -P allow_polyinstantiation 1
78 If you want to allow sysadm to debug or ptrace all processes, you must
82 turn on the allow_ptrace boolean. Disabled by default.
83 setsebool -P allow_ptrace 1
85 If you want to allow system to run with NIS, you must turn on the
89 allow_ypbind boolean. Disabled by default.
90 setsebool -P allow_ypbind 1
92 If you want to allow all domains to have the kernel load modules, you
96 must turn on the domain_kernel_load_modules boolean. Disabled by
97 default.
98 setsebool -P domain_kernel_load_modules 1
100 If you want to allow all domains to execute in fips_mode, you must turn
104 on the fips_mode boolean. Enabled by default.
105 setsebool -P fips_mode 1
107 If you want to enable reading of urandom for all domains, you must turn
111 on the global_ssp boolean. Disabled by default.
112 setsebool -P global_ssp 1
114 If you want to allow confined applications to use nscd shared memory,
118 you must turn on the nscd_use_shm boolean. Enabled by default.
119 setsebool -P nscd_use_shm 1
121 If you want to enabling secure mode disallows programs, such as new‐
125 role, from transitioning to administrative user domains, you must turn
126 on the secure_mode boolean. Disabled by default.
127 setsebool -P secure_mode 1
129
133 The SELinux process type newrole_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.

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