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 direct login to the console device. Required for
56 System 390, you must turn on the allow_console_login boolean. Enabled
57 by default.
58 setsebool -P allow_console_login 1
60 If you want to allow all domains to use other domains file descriptors,
64 you must turn on the allow_domain_fd_use boolean. Enabled by default.
65 setsebool -P allow_domain_fd_use 1
67 If you want to allow unconfined executables to map a memory region as
71 both executable and writable, this is dangerous and the executable
72 should be reported in bugzilla), you must turn on the allow_execmem
73 boolean. Enabled by default.
74 setsebool -P allow_execmem 1
76 If you want to allow unconfined executables to make their stack exe‐
80 cutable. This should never, ever be necessary. Probably indicates a
81 badly coded executable, but could indicate an attack. This executable
82 should be reported in bugzilla), you must turn on the allow_execstack
83 boolean. Enabled by default.
84 setsebool -P allow_execstack 1
86 If you want to allow confined applications to run with kerberos, you
90 must turn on the allow_kerberos boolean. Enabled by default.
91 setsebool -P allow_kerberos 1
93 If you want to allow sysadm to debug or ptrace all processes, you must
97 turn on the allow_ptrace boolean. Disabled by default.
98 setsebool -P allow_ptrace 1
100 If you want to allow system to run with NIS, you must turn on the
104 allow_ypbind boolean. Disabled by default.
105 setsebool -P allow_ypbind 1
107 If you want to allow all domains to have the kernel load modules, you
111 must turn on the domain_kernel_load_modules boolean. Disabled by
112 default.
113 setsebool -P domain_kernel_load_modules 1
115 If you want to allow all domains to execute in fips_mode, you must turn
119 on the fips_mode boolean. Enabled by default.
120 setsebool -P fips_mode 1
122 If you want to enable reading of urandom for all domains, you must turn
126 on the global_ssp boolean. Disabled by default.
127 setsebool -P global_ssp 1
129 If you want to allow confined applications to use nscd shared memory,
133 you must turn on the nscd_use_shm boolean. Enabled by default.
134 setsebool -P nscd_use_shm 1
136 If you want to enabling secure mode disallows programs, such as new‐
140 role, from transitioning to administrative user domains, you must turn
141 on the secure_mode boolean. Disabled by default.
142 setsebool -P secure_mode 1
144 If you want to allow ssh logins as sysadm_r:sysadm_t, you must turn on
148 the ssh_sysadm_login boolean. Disabled by default.
149 setsebool -P ssh_sysadm_login 1
151 If you want to allow xdm logins as sysadm, you must turn on the
155 xdm_sysadm_login boolean. Disabled by default.
156 setsebool -P xdm_sysadm_login 1

163 following file types. The paths listed are the default paths for these

244 semanage fcontext can also be used to manipulate default file context
245 mappings.
246 semanage permissive can also be used to manipulate whether or not a
248 process type is permissive.
249 semanage module can also be used to enable/disable/install/remove pol‐
251 icy modules.
252 semanage boolean can also be used to manipulate the booleans
254 system-config-selinux is a GUI tool available to customize SELinux pol‐
257 icy settings.
