DISK_MUNIN_PLUGIN_SELINUX(8)

💖 disk_munin_plugin_selinux(8) — the SELinux policy page for disk_munin_plugin 💖

okay so bestie, this is the manual page for disk_munin_plugin_selinux from section 8 of the manual (that's the admin/system commands girlies), and it's literally all about the Security Enhanced Linux Policy for the disk_munin_plugin processes. buckle up 🎀

✨ NAME ✨

disk_munin_plugin_selinux — Security Enhanced Linux Policy for the disk_munin_plugin processes. periodt. 💅

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the disk_munin_plugin processes via flexible mandatory access control. yes bestie, MAC is THAT girl — it's not just vibes, it's enforced policy 🔥

The disk_munin_plugin processes execute with the disk_munin_plugin_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier.

For example:

ps -eZ | grep disk_munin_plugin_t

go off, -Z. the way that one flag tells you literally everything about a process's security context 😭✨

---

🦋 ENTRYPOINTS 🦋

The disk_munin_plugin_t SELinux type can be entered via the disk_munin_plugin_exec_t file type.

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

/usr/share/munin/plugins/df.*, /usr/share/munin/plugins/smart_.*,
/usr/share/munin/plugins/hddtemp.*, /usr/share/munin/plugins/diskstat.*

four little doorways into the domain, no cap 🚪🫶

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system.

You can see the context of a process using the -Z option to ps.

Policy governs the access confined processes have to files. SELinux disk_munin_plugin policy is very flexible allowing users to setup their disk_munin_plugin processes in as secure a method as possible. highkey iconic behavior ngl.

The following process types are defined for disk_munin_plugin:

• disk_munin_plugin_t

Note: semanage permissive -a disk_munin_plugin_t can be used to make the process type disk_munin_plugin_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it stops blocking you but it still talks about you 💀 the receipts stay, bestie.

---

🎀 BOOLEANS 🎀

SELinux policy is customizable based on least access required. disk_munin_plugin policy is extremely flexible and has several booleans that allow you to manipulate the policy and run disk_munin_plugin with the tightest access possible. we love a minimal-privilege queen 👑

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default.

setsebool -P fips_mode 1

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

that -P is the persistent flag btw, she's not doing throwaway changes 🙈

---

🌈 MANAGED FILES 🌈

The SELinux process type disk_munin_plugin_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note the processes UID still need to have DAC permissions — SELinux is not out here doing DAC's job for it, fr fr.

• disk_munin_plugin_tmp_t
• krb5_host_rcache_t

/var/tmp/krb5_0.rcache2
/var/cache/krb5rcache(/.*)?
/var/tmp/nfs_0
/var/tmp/DNS_25
/var/tmp/host_0
/var/tmp/imap_0
/var/tmp/HTTP_23
/var/tmp/HTTP_48
/var/tmp/ldap_55
/var/tmp/ldap_487
/var/tmp/ldapmap1_0

• munin_plugin_state_t

/var/lib/munin/plugin-state(/.*)?

• munin_var_lib_t

/var/lib/munin(/.*)?

look at all those regex path patterns, she's giving regular-expression royalty 🧚✨

---

⭐ FILE CONTEXTS ⭐

SELinux requires files to have an extended attribute to define the file type.

You can see the context of a file using the -Z option to ls. (yes, same -Z energy, different command — she's versatile 💅)

Policy governs the access confined processes have to these files. SELinux disk_munin_plugin policy is very flexible allowing users to setup their disk_munin_plugin processes in as secure a method as possible.

🌸 STANDARD FILE CONTEXT 🌸

SELinux defines the file context types for the disk_munin_plugin, 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.

semanage fcontext -a -t disk_munin_plugin_exec_t '/srv/disk_munin_plugin/content(/.*)?'
restorecon -R -v /srv/mydisk_munin_plugin_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. it's giving pattern matching main character energy 🔍

The following file types are defined for disk_munin_plugin:

disk_munin_plugin_exec_t

• Set files with the disk_munin_plugin_exec_t type, if you want to transition an executable to the disk_munin_plugin_t domain.

Paths:

/usr/share/munin/plugins/df.*, /usr/share/munin/plugins/smart_.*,
/usr/share/munin/plugins/hddtemp.*, /usr/share/munin/plugins/diskstat.*

disk_munin_plugin_tmp_t

• Set files with the disk_munin_plugin_tmp_t type, if you want to store disk munin plugin temporary files in the /tmp directories.

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 the temporary fix-up bestie and semanage fcontext + restorecon is the real glow-up 💖

---

🫶 COMMANDS 🫶

• semanage fcontext can also be used to manipulate default file context mappings.
• semanage permissive can also be used to manipulate whether or not a process type is permissive.
• semanage module can also be used to enable/disable/install/remove policy modules.
• semanage boolean can also be used to manipulate the booleans.
• system-config-selinux is a GUI tool available to customize SELinux policy settings. (a GUI!! for the girlies who like clicking 🖱️✨)
