quota_selinux(8)

💖 quota_selinux(8) — the SELinux glow-up for quota 💖

okay so bestie, welcome to the manual page for quota_selinux, which is literally the Security Enhanced Linux Policy for the quota processes. no cap, this is where the mandatory access control magic happens. ✨

---

🌸 NAME 🌸

quota_selinux — Security Enhanced Linux Policy for the quota processes. that's it, that's the vibe. 💅

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the quota processes via flexible mandatory access control. yes, flexible and mandatory, it's giving main character energy fr fr. 😌

The quota processes execute with the quota_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. like this, bestie:

ps -eZ | grep quota_t

run that and see what's what. 🫶

---

🎀 ENTRYPOINTS 🎀

The quota_t SELinux type can be entered via the quota_exec_t file type. that's the doorway, okay? 🚪✨

The default entrypoint paths for the quota_t domain are the following:

/usr/bin/quota(check|on), /usr/bin/convertquota

those are literally the paths that let you in. iconic. 💫

---

🌈 PROCESS TYPES 🌈

SELinux defines process types (domains) for each process running on the system. every process gets its own little label, it's a whole thing. 🏷️

You can see the context of a process using the -Z option to ps. just add that flag and you'll see the security context, no biggie.

Policy governs the access confined processes have to files. SELinux quota policy is very flexible allowing users to setup their quota processes in as secure a method as possible. like, you can lock things down and have it work. the duality. 💅

The following process types are defined for quota:

quota_t, quota_nld_t

so those are the two icons of the quota world. 👑

Note: semanage permissive -a quota_t can be used to make the process type quota_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so it's chill but it still snitches. 💀

---

🔥 BOOLEANS 🔥

SELinux policy is customizable based on least access required. quota policy is extremely flexible and has several booleans that allow you to manipulate the policy and run quota with the tightest access possible. like, you can really fine-tune the vibe. 🎛️

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. yes bestie, it's on by default, that's the standard.

setsebool -P fips_mode 1

run that if you need to flip it on explicitly, but again, it's already enabled. just keeping you informed. 💖

---

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. like, every file needs its little name tag. 📛

You can see the context of a file using the -Z option to ls. try it, it's cute.

Policy governs the access confined processes have to these files. SELinux quota policy is very flexible allowing users to setup their quota processes in as secure a method as possible. same energy as before, just for files this time. 🌸

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the quota, if you wanted to store files with these types in a different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk. okay so here's the duo you need:

semanage fcontext -a -t quota_exec_t '/srv/quota/content(/.*)?'
restorecon -R -v /srv/myquota_content

that's literally the whole process. semanage tells SELinux what's up, restorecon puts it into action. periodt. 💅

Note: SELinux often uses regular expressions to specify labels that match multiple files. so those (/.*)? bits aren't just for show, they're doing the most. 😭

The following file types are defined for quota:

• quota_db_t — Set files with the quota_db_t type, if you want to treat the files as quota database content. Paths: /a?quota.(user|group), /etc/a?quota.(user|group), /var/a?quota.(user|group), /boot/a?quota.(user|group), /var/spool/(.*/)?a?quota.(user|group), /var/spool/cron/a?quota.(user|group), /var/lib/openshift/a?quota.(user|group), /var/lib/stickshift/a?quota.(user|group), /home/[^/]+/a?quota.(user|group), /home/a?quota.(user|group)
• quota_exec_t — Set files with the quota_exec_t type, if you want to transition an executable to the quota_t domain. Paths: /usr/bin/quota(check|on), /usr/bin/convertquota
• quota_flag_t — Set files with the quota_flag_t type, if you want to treat the files as quota flag data.
• quota_nld_exec_t — Set files with the quota_nld_exec_t type, if you want to transition an executable to the quota_nld_t domain.
• quota_nld_var_run_t — Set files with the quota_nld_var_run_t type, if you want to store the quota nld files under the /run or /var/run directory.

Note: File context can be temporarily modified with the chcon command. If you want to permanently change the file context you need to use the semanage fcontext command. This will modify the SELinux labeling database. You will need to use restorecon to apply the labels. so chcon is like a temporary tattoo, semanage fcontext is the real ink. choose wisely. 🫶

💜 COMMANDS 💜

semanage fcontext can also be used to manipulate default file context mappings. yes, it's the same tool, it does a lot. multi-talented icon.

semanage permissive can also be used to manipulate whether or not a process type is permissive. so if you need to chill out a process type, that's your command.

semanage module can also be used to enable/disable/install/remove policy modules. modules are like little policy add-ons, and you can manage them here.

semanage boolean can also be used to manipulate the booleans. remember those from earlier? this is how you flip them.

system-config-selinux is a GUI tool available to customize SELinux policy settings. if you're a visual person, that's your bestie. 🖥️✨

so that's the whole page, bestie. go forth and manage your quota SELinux policy with confidence. you've got this. and if you need to find this manual again, it's from quota version 26-10-06, dated 26-10-06, and it's the quota_selinux(8) page. mwah! 💋✨
