DESCRIPTION

11       staff_u is an SELinux User defined in the SELinux policy. SELinux users
12       have  default  roles,  staff_r.   The  default role has a default type,
13       staff_t, associated with it.
14
15       The SELinux user will usually login to a system  with  a  context  that
16       looks like:
17
18       staff_u:staff_r:staff_t:s0 - s0:c0.c1023
19
20       Linux  users  are  automatically  assigned  an  SELinux users at login.
21       Login programs use the SELinux User to assign initial  context  to  the
22       user's shell.
23
24       SELinux policy uses the context to control the user's access.
25
26       By  default  all  users  are  assigned  to  the  SELinux  user  via the
27       __default__ flag
28
29       On Targeted policy systems the __default__  user  is  assigned  to  the
30       unconfined_u SELinux user.
31
32       You can list all Linux User to SELinux user mapping using:
33
34       semanage login -l
35
36       If  you  wanted  to  change the default user mapping to use the staff_u
37       user, you would execute:
38
39       semanage login -m -s staff_u __default__
40
41
42       If you want to map the one Linux user (joe) to the SELinux user  staff,
43       you would execute:
44
45       $ semanage login -a -s staff_u joe
46

USER DESCRIPTION

50       The  SELinux  user staff_u is defined in policy as a unprivileged user.
51       SELinux prevents unprivileged users  from  doing  administration  tasks
52       without transitioning to a different role.
53
54

SUDO

56       The SELinux user staff can execute sudo.
57
58       You  can  set up sudo to allow staff to transition to an administrative
59       domain:

385       cutable.  This should never, ever be necessary.  Probably  indicates  a

387       should be reported in bugzilla, you must turn on the  selinuxuser_exec‐
388       stack boolean. Enabled by default.

HOME_EXEC

440       The SELinux user staff_u is able execute home content files.
441
442

TRANSITIONS

444       Three things can happen when staff_t attempts to execute a program.
445
446       1. SELinux Policy can deny staff_t from executing the program.
447
448
449
450       2. SELinux Policy can allow staff_t to execute the program in the  cur‐
451       rent user type.
452
453              Execute  the  following  to  see the types that the SELinux user
454              staff_t can execute without transitioning:
455
456              sesearch -A -s staff_t -c file -p execute_no_trans
457
458
459
460       3. SELinux can allow staff_t to execute the program and transition to a
461       new type.
462
463              Execute  the  following  to  see the types that the SELinux user
464              staff_t can execute and transition:
465
466              $ sesearch -A -s staff_t -c process -p transition
467
468
469

MANAGED FILES

471       The SELinux process type staff_t can manage files labeled with the fol‐
472       lowing  file  types.   The paths listed are the default paths for these
473       file types.  Note the processes UID still need to have DAC permissions.
