10 SELinux supports Roles Based Access Control (RBAC), some Linux roles
11 are login roles, while other roles need to be transition into.
12
13 Note: Examples in this man page will use the staff_u SELinux user.
14
15 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
20 The default type for the logadm_r role is logadm_t.
21
22 The newrole program to transition directly to this role.
23
24 newrole -r logadm_r -t logadm_t
25
26 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
30 USERNAME ALL=(ALL) ROLE=logadm_r TYPE=logadm_t COMMAND
31
32 sudo will run COMMAND as staff_u:logadm_r:logadm_t:LEVEL
33
34 When using a non login role, you need to setup SELinux so that your
35 SELinux user can reach logadm_r role.
36
37 Execute the following to see all of the assigned SELinux roles:
38
39 semanage user -l
40
41 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
44 $ semanage user -m -R 'staff_r system_r logadm_r' staff_u
45

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.

55 If you want to deny user domains applications to map a memory region as
56 both executable and writable, this is dangerous and the executable
57 should be reported in bugzilla, you must turn on the deny_execmem bool‐
58 ean. Enabled by default.
59
60 setsebool -P deny_execmem 1
61
62
63
64 If you want to deny any process from ptracing or debugging any other
65 processes, you must turn on the deny_ptrace boolean. Enabled by de‐
66 fault.
67
68 setsebool -P deny_ptrace 1
69
70
71
72 If you want to allow all domains to execute in fips_mode, you must turn
73 on the fips_mode boolean. Enabled by default.
74
75 setsebool -P fips_mode 1
76
77
78
79 If you want to allow system to run with NIS, you must turn on the
80 nis_enabled boolean. Disabled by default.
81
82 setsebool -P nis_enabled 1
83
84
85
86 If you want to allow unconfined executables to make their stack exe‐
87 cutable. This should never, ever be necessary. Probably indicates a
88 badly coded executable, but could indicate an attack. This executable
89 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
90 stack boolean. Enabled by default.
91
92 setsebool -P selinuxuser_execstack 1
93

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