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 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 all domains to execute in fips_mode, you must turn
81 on the fips_mode boolean. Enabled by default.
82 setsebool -P fips_mode 1
84 If you want to allow confined applications to run with kerberos, you
88 must turn on the kerberos_enabled boolean. Disabled by default.
89 setsebool -P kerberos_enabled 1
91 If you want to allow system to run with NIS, you must turn on the
95 nis_enabled boolean. Disabled by default.
96 setsebool -P nis_enabled 1
98 If you want to allow confined applications to use nscd shared memory,
102 you must turn on the nscd_use_shm boolean. Disabled by default.
103 setsebool -P nscd_use_shm 1
105 If you want to allow unconfined executables to make their stack exe‐
109 cutable. This should never, ever be necessary. Probably indicates a
110 badly coded executable, but could indicate an attack. This executable
111 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
112 stack boolean. Disabled by default.
113 setsebool -P selinuxuser_execstack 1

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

185 semanage fcontext can also be used to manipulate default file context
186 mappings.
187 semanage permissive can also be used to manipulate whether or not a
189 process type is permissive.
190 semanage module can also be used to enable/disable/install/remove pol‐
192 icy modules.
193 semanage boolean can also be used to manipulate the booleans
195 system-config-selinux is a GUI tool available to customize SELinux pol‐
198 icy settings.
