6 dbadm_r - Database administrator role. - Security Enhanced Linux Policy

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 dbadm_r role is dbadm_t.
21 The newrole program to transition directly to this role.
23 newrole -r dbadm_r -t dbadm_t
25 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 USERNAME ALL=(ALL) ROLE=dbadm_r TYPE=dbadm_t COMMAND
31 sudo will run COMMAND as staff_u:dbadm_r:dbadm_t:LEVEL
33 When using a non login role, you need to setup SELinux so that your
35 SELinux user can reach dbadm_r role.
36 Execute the following to see all of the assigned SELinux roles:
38 semanage user -l
40 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 $ semanage user -m -R 'staff_r system_r dbadm_r' staff_u

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 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 de‐
57 fault.
58 setsebool -P dbadm_manage_user_files 1
60 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 setsebool -P dbadm_read_user_files 1
67 If you want to deny user domains applications 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 deny_execmem bool‐
73 ean. Disabled by default.
74 setsebool -P deny_execmem 1
76 If you want to deny any process from ptracing or debugging any other
80 processes, you must turn on the deny_ptrace boolean. Disabled by de‐
81 fault.
82 setsebool -P deny_ptrace 1
84 If you want to allow all domains to execute in fips_mode, you must turn
88 on the fips_mode boolean. Enabled by default.
89 setsebool -P fips_mode 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 unconfined executables to make their stack exe‐
102 cutable. This should never, ever be necessary. Probably indicates a
103 badly coded executable, but could indicate an attack. This executable
104 should be reported in bugzilla, you must turn on the selinuxuser_exec‐
105 stack boolean. Enabled by default.
106 setsebool -P selinuxuser_execstack 1
108 If you want to support NFS home directories, you must turn on the
112 use_nfs_home_dirs boolean. Disabled by default.
113 setsebool -P use_nfs_home_dirs 1
115 If you want to support SAMBA home directories, you must turn on the
119 use_samba_home_dirs boolean. Disabled by default.
120 setsebool -P use_samba_home_dirs 1

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

223 semanage fcontext can also be used to manipulate default file context
224 mappings.
225 semanage permissive can also be used to manipulate whether or not a
227 process type is permissive.
228 semanage module can also be used to enable/disable/install/remove pol‐
230 icy modules.
231 semanage boolean can also be used to manipulate the booleans
233 system-config-selinux is a GUI tool available to customize SELinux pol‐
236 icy settings.
