6 run_init_selinux - Security Enhanced Linux Policy for the run_init pro‐
7 cesses
8
10 Security-Enhanced Linux secures the run_init processes via flexible
11 mandatory access control.
12 The run_init processes execute with the run_init_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 run_init_t
20
24 The run_init_t SELinux type can be entered via the run_init_exec_t file
25 type.
26 The default entrypoint paths for the run_init_t domain are the follow‐
28 ing:
29 /usr/sbin/run_init
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 run_init policy is very flexible allowing users to setup their run_init
40 processes in as secure a method as possible.
41 The following process types are defined for run_init:
43 run_init_t
45 Note: semanage permissive -a run_init_t can be used to make the process
47 type run_init_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.
54 run_init policy is extremely flexible and has several booleans that
55 allow you to manipulate the policy and run run_init with the tightest
56 access possible.
57 If you want to allow users to resolve user passwd entries directly from
61 ldap rather then using a sssd server, you must turn on the authlo‐
62 gin_nsswitch_use_ldap boolean. Disabled by default.
63 setsebool -P authlogin_nsswitch_use_ldap 1
65 If you want to deny any process from ptracing or debugging any other
69 processes, you must turn on the deny_ptrace boolean. Enabled by
70 default.
71 setsebool -P deny_ptrace 1
73 If you want to allow any process to mmap any file on system with
77 attribute file_type, you must turn on the domain_can_mmap_files bool‐
78 ean. Enabled by default.
79 setsebool -P domain_can_mmap_files 1
81 If you want to allow all domains write to kmsg_device, while kernel is
85 executed with systemd.log_target=kmsg parameter, you must turn on the
86 domain_can_write_kmsg boolean. Disabled by default.
87 setsebool -P domain_can_write_kmsg 1
89 If you want to allow all domains to use other domains file descriptors,
93 you must turn on the domain_fd_use boolean. Enabled by default.
94 setsebool -P domain_fd_use 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 allow confined applications to run with kerberos, you
122 must turn on the kerberos_enabled boolean. Enabled by default.
123 setsebool -P kerberos_enabled 1
125 If you want to allow system to run with NIS, you must turn on the
129 nis_enabled boolean. Disabled by default.
130 setsebool -P nis_enabled 1
132 If you want to allow confined applications to use nscd shared memory,
136 you must turn on the nscd_use_shm boolean. Disabled by default.
137 setsebool -P nscd_use_shm 1
139
143 The SELinux process type run_init_t can manage files labeled with the
144 following file types. The paths listed are the default paths for these
145 file types. Note the processes UID still need to have DAC permissions.
146 faillog_t
148 /var/log/btmp.*
150 /var/log/faillog.*
151 /var/log/tallylog.*
152 /var/run/faillock(/.*)?
153 initrc_var_run_t
155 /var/run/utmp
157 /var/run/random-seed
158 /var/run/runlevel.dir
159 /var/run/setmixer_flag
160 security_t
162 /selinux
164
167 SELinux requires files to have an extended attribute to define the file
168 type.
169 You can see the context of a file using the -Z option to ls
171 Policy governs the access confined processes have to these files.
173 SELinux run_init policy is very flexible allowing users to setup their
174 run_init processes in as secure a method as possible.
175 The following file types are defined for run_init:
177 run_init_exec_t
181 - Set files with the run_init_exec_t type, if you want to transition an
183 executable to the run_init_t domain.
184 Note: File context can be temporarily modified with the chcon command.
188 If you want to permanently change the file context you need to use the
189 semanage fcontext command. This will modify the SELinux labeling data‐
190 base. You will need to use restorecon to apply the labels.
191
194 semanage fcontext can also be used to manipulate default file context
195 mappings.
196 semanage permissive can also be used to manipulate whether or not a
198 process type is permissive.
199 semanage module can also be used to enable/disable/install/remove pol‐
201 icy modules.
202 semanage boolean can also be used to manipulate the booleans
204 system-config-selinux is a GUI tool available to customize SELinux pol‐
207 icy settings.
