6 logadm_r - Log administrator role - Security Enhanced Linux Policy
7
10 SELinux supports Roles Based Access Control (RBAC), some Linux roles
11 are login roles, while other roles need to be transition into.
12 Note: Examples in this man page will use the staff_u SELinux user.
14 Non login roles are usually used for administrative tasks. For example,
16 tasks that require root privileges. Roles control which types a user
17 can run processes with. Roles often have default types assigned to
18 them.
19 The default type for the logadm_r role is logadm_t.
21 The newrole program to transition directly to this role.
23 newrole -r logadm_r -t logadm_t
25 sudo is the preferred method to do transition from one role to another.
27 You setup sudo to transition to logadm_r by adding a similar line to
28 the /etc/sudoers file.
29 USERNAME ALL=(ALL) ROLE=logadm_r TYPE=logadm_t COMMAND
31 sudo will run COMMAND as staff_u:logadm_r:logadm_t:LEVEL
33 When using a a non login role, you need to setup SELinux so that your
35 SELinux user can reach logadm_r role.
36 Execute the following to see all of the assigned SELinux roles:
38 semanage user -l
40 You need to add logadm_r to the staff_u user. You could setup the
42 staff_u user to be able to use the logadm_r role with a command like:
43 $ semanage user -m -R 'staff_r system_r logadm_r' staff_u

49 SELinux policy is customizable based on least access required. logadm
50 policy is extremely flexible and has several booleans that allow you to
51 manipulate the policy and run logadm with the tightest access possible.
52 If you want to allow users to resolve user passwd entries directly from
56 ldap rather then using a sssd server, you must turn on the authlo‐
57 gin_nsswitch_use_ldap boolean. Disabled by default.
58 setsebool -P authlogin_nsswitch_use_ldap 1
60 If you want to deny user domains applications to map a memory region as
64 both executable and writable, this is dangerous and the executable
65 should be reported in bugzilla, you must turn on the deny_execmem bool‐
66 ean. Enabled by default.
67 setsebool -P deny_execmem 1
69 If you want to deny any process from ptracing or debugging any other
73 processes, you must turn on the deny_ptrace boolean. Enabled by
74 default.
75 setsebool -P deny_ptrace 1
77 If you want to allow any process to mmap any file on system with
81 attribute file_type, you must turn on the domain_can_mmap_files bool‐
82 ean. Enabled by default.
83 setsebool -P domain_can_mmap_files 1
85 If you want to allow all domains write to kmsg_device, while kernel is
89 executed with systemd.log_target=kmsg parameter, you must turn on the
90 domain_can_write_kmsg boolean. Disabled by default.
91 setsebool -P domain_can_write_kmsg 1
93 If you want to allow all domains to use other domains file descriptors,
97 you must turn on the domain_fd_use boolean. Enabled by default.
98 setsebool -P domain_fd_use 1
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 allow confined applications to run with kerberos, you
126 must turn on the kerberos_enabled boolean. Enabled by default.
127 setsebool -P kerberos_enabled 1
129 If you want to allow logging in and using the system from /dev/console,
133 you must turn on the login_console_enabled boolean. Enabled by default.
134 setsebool -P login_console_enabled 1
136 If you want to allow system to run with NIS, you must turn on the
140 nis_enabled boolean. Disabled by default.
141 setsebool -P nis_enabled 1
143 If you want to allow confined applications to use nscd shared memory,
147 you must turn on the nscd_use_shm boolean. Disabled by default.
148 setsebool -P nscd_use_shm 1
150 If you want to disallow programs, such as newrole, from transitioning
154 to administrative user domains, you must turn on the secure_mode bool‐
155 ean. Enabled by default.
156 setsebool -P secure_mode 1
158 If you want to allow unconfined executables to make their stack exe‐
162 cutable. This should never, ever be necessary. Probably indicates a
163 badly coded executable, but could indicate an attack. This executable
164 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
165 stack boolean. Enabled by default.
166 setsebool -P selinuxuser_execstack 1
168 If you want to allow ssh logins as sysadm_r:sysadm_t, you must turn on
172 the ssh_sysadm_login boolean. Disabled by default.
173 setsebool -P ssh_sysadm_login 1
175 If you want to support NFS home directories, you must turn on the
179 use_nfs_home_dirs boolean. Disabled by default.
180 setsebool -P use_nfs_home_dirs 1
182 If you want to support SAMBA home directories, you must turn on the
186 use_samba_home_dirs boolean. Disabled by default.
187 setsebool -P use_samba_home_dirs 1
189 If you want to allow the graphical login program to login directly as
193 sysadm_r:sysadm_t, you must turn on the xdm_sysadm_login boolean. Dis‐
194 abled by default.
195 setsebool -P xdm_sysadm_login 1

201 The SELinux process type logadm_t can manage files labeled with the
202 following file types. The paths listed are the default paths for these
203 file types. Note the processes UID still need to have DAC permissions.

267 semanage fcontext can also be used to manipulate default file context
268 mappings.
269 semanage permissive can also be used to manipulate whether or not a
271 process type is permissive.
272 semanage module can also be used to enable/disable/install/remove pol‐
274 icy modules.
275 semanage boolean can also be used to manipulate the booleans
277 system-config-selinux is a GUI tool available to customize SELinux pol‐
280 icy settings.
