staff_selinux(8)
πΈ NAME πΈ
ok so this is the manual page for staff_selinux(8) β the header up top literally says staff SELinux Policy documentation, that's this page π
β and the whole thing is about:
staff_u β Administrator's unprivileged user β Security Enhanced Linux Policy
yes bestie, "administrator's unprivileged user" is a real phrase, we love an oxymoron, moving on π«Ά
β¨ DESCRIPTION β¨
staff_u is an SELinux User defined in the SELinux policy. SELinux users have default roles, staff_r. The default role has a default type, staff_t, associated with it.
The SELinux user will usually login to a system with a context that looks like:
staff_u:staff_r:staff_t:s0 - s0:c0.c1023
Linux users are automatically assigned an SELinux users at login. Login programs use the SELinux User to assign initial context to the user's shell.
SELinux policy uses the context to control the user's access.
By default all users are assigned to the SELinux user via the __default__ flag.
On Targeted policy systems the __default__ user is assigned to the unconfined_u SELinux user.
You can list all Linux User to SELinux user mapping using:
semanage login -l
If you wanted to change the default user mapping to use the staff_u user, you would execute:
semanage login -m -s staff_u __default__
If you want to map the one Linux user (joe) to the SELinux user staff, you would execute:
$ semanage login -a -s staff_u joe
(joe is main character of this man page fr, we love joe π)
π USER DESCRIPTION π
The SELinux user staff_u is defined in policy as a unprivileged user. SELinux prevents unprivileged users from doing administration tasks without transitioning to a different role.
like, that's the whole vibe: you're staff, you're not root, and if you want admin stuff you gotta transition to another role. periodt π
π₯ SUDO π₯
The SELinux user staff can execute sudo.
You can set up sudo to allow staff to transition to an administrative domain:
Add one or more of the following record to sudoers using visudo.
πΈοΈ the webadm_r one
USERNAME ALL=(ALL) ROLE=webadm_r TYPE=webadm_t COMMAND
sudo will run COMMAND as staff_u:webadm_r:webadm_t:LEVEL

$ semanage user -l |grep selinux_name
Modify the roles list and add staff_r to this list.

π and after ALL of that, plot twist: the SELinux type staff_t is not allowed to execute sudo.
not me reading seven whole sudo recipes just for the page to say the base type can't sudo π that's the transition stuff we were talking about, bestie β the type matters.
π₯οΈ X WINDOWS LOGIN π₯οΈ
The SELinux user staff_u is able to X Windows login.
graphical login? slay. β¨
π NETWORK π
The SELinux user staff_u is able to listen on the following tcp ports:
- all ports without defined types
6000-6020171632768-609993689- all ports >=
1024
The SELinux user staff_u is able to connect to the following tcp ports:
895553,853- all ports
389,636,3268,3269,7389- all ports without defined types
32768-60999- all ports <
1024 908088,750,4444
The SELinux user staff_u is able to listen on the following udp ports:
32768-609995353- all ports without defined types
1716- all ports >=
1024

32768-60999- all ports <
1024 908088,750,4444
π yes it says "tcp ports" a second time at the end with the exact same list, no I'm not fixing it, that's literally what the page says π
ποΈ BOOLEANS ποΈ
SELinux policy is customizable based on least access required. staff policy is extremely flexible and has several booleans that allow you to manipulate the policy and run staff with the tightest access possible.
like, these are your toggles bestie, flip with care π«Ά

π HOME_EXEC π
The SELinux user staff_u is able execute home content files.
your ~ stuff? executable by staff? yes bestie π
π¦ that's the tea so far β this page literally keeps going, so keep reading, part two is right there β¨
π TRANSITIONS π
ok so bestie, when staff_t tries to run a program, exactly three things can go down. three. not two, not four. bestie math π
- SELinux Policy can straight-up deny
staff_tfrom executing the program. like, blocked. no entry. π - SELinux Policy can allow
staff_tto execute the program in the current user type. no glow-up, no transformation, just runs as-is.
wanna see which types the SELinux user staff_t can execute without transitioning? run this, bestie:
sesearch -A -s staff_t -c file -p execute_no_trans
- SELinux can allow
staff_tto execute the program and transition to a new type. it's giving main character energy β the process literally becomes someone new β¨
and to see which types the SELinux user staff_t can execute and transition into:
$ sesearch -A -s staff_t -c process -p transition
π MANAGED FILES π
okay so the SELinux process type staff_t can manage files labeled with the following file types. the paths listed are the default paths for these file types. and hiii, important reminder: the process's UID still needs to have DAC permissions. so like, SELinux saying yes doesn't mean the universe says yes π«Ά
