DESCRIPTION

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 dbadm_r role is dbadm_t.
21
22       The newrole program to transition directly to this role.
23
24       newrole -r dbadm_r -t dbadm_t
25
26       sudo is the preferred method to do transition from one role to another.
27       You setup sudo to transition to dbadm_r by adding a similar line to the
28       /etc/sudoers file.
29
30       USERNAME ALL=(ALL) ROLE=dbadm_r TYPE=dbadm_t COMMAND
31
32       sudo will run COMMAND as staff_u:dbadm_r:dbadm_t:LEVEL
33
34       When  using  a  non  login role, you need to setup SELinux so that your
35       SELinux user can reach dbadm_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 dbadm_r to the  staff_u  user.   You  could  setup  the
42       staff_u user to be able to use the dbadm_r role with a command like:
43
44       $ semanage user -m -R 'staff_r system_r dbadm_r' staff_u

BOOLEANS

49       SELinux  policy  is customizable based on least access required.  dbadm
50       policy is extremely flexible and has several booleans that allow you to
51       manipulate the policy and run dbadm with the tightest access possible.
52
53
54
55       If  you  want to determine whether dbadm can manage generic user files,
56       you must turn  on  the  dbadm_manage_user_files  boolean.  Disabled  by
57       default.
58
59       setsebool -P dbadm_manage_user_files 1
60
61
62
63       If you want to determine whether dbadm can read generic user files, you
64       must turn on the dbadm_read_user_files boolean. Disabled by default.
65
66       setsebool -P dbadm_read_user_files 1
67
68
69
70       If you want to allow users to resolve user passwd entries directly from
71       ldap  rather  then  using  a  sssd server, you must turn on the authlo‐
72       gin_nsswitch_use_ldap boolean. Disabled by default.
73
74       setsebool -P authlogin_nsswitch_use_ldap 1
75
76
77
78       If you want to deny user domains applications to map a memory region as
79       both  executable  and  writable,  this  is dangerous and the executable
80       should be reported in bugzilla, you must turn on the deny_execmem bool‐
81       ean. Enabled by default.
82
83       setsebool -P deny_execmem 1
84
85
86
87       If  you  want  to deny any process from ptracing or debugging any other
88       processes, you  must  turn  on  the  deny_ptrace  boolean.  Enabled  by
89       default.
90
91       setsebool -P deny_ptrace 1
92
93
94
95       If you want to allow all domains to execute in fips_mode, you must turn
96       on the fips_mode boolean. Enabled by default.
97
98       setsebool -P fips_mode 1
99
100
101
102       If you want to allow confined applications to run  with  kerberos,  you
103       must turn on the kerberos_enabled boolean. Disabled by default.
104
105       setsebool -P kerberos_enabled 1
106
107
108
109       If  you  want  to  allow  system  to run with NIS, you must turn on the
110       nis_enabled boolean. Disabled by default.
111
112       setsebool -P nis_enabled 1
113
114
115
116       If you want to allow confined applications to use nscd  shared  memory,
117       you must turn on the nscd_use_shm boolean. Disabled by default.
118
119       setsebool -P nscd_use_shm 1
120
121
122
123       If  you  want  to allow unconfined executables to make their stack exe‐
124       cutable.  This should never, ever be necessary.  Probably  indicates  a
125       badly  coded  executable, but could indicate an attack. This executable
126       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
127       stack boolean. Disabled by default.
128
129       setsebool -P selinuxuser_execstack 1

MANAGED FILES

134       The SELinux process type dbadm_t can manage files labeled with the fol‐
135       lowing file types.  The paths listed are the default  paths  for  these
136       file types.  Note the processes UID still need to have DAC permissions.

231       semanage  fcontext  can also be used to manipulate default file context
232       mappings.
233
234       semanage permissive can also be used to manipulate  whether  or  not  a
235       process type is permissive.
236
237       semanage  module can also be used to enable/disable/install/remove pol‐
238       icy modules.
239
240       semanage boolean can also be used to manipulate the booleans
241
