netlabel_mgmt_selinux(8)

✨ netlabel_mgmt_selinux ✨

Okay so bestie, welcome to the manual page for netlabel_mgmt_selinux — it's the Security Enhanced Linux Policy for the netlabel_mgmt processes, and honestly? It's giving "I keep your stuff locked down" energy. 💅 This is section 8 of the manual, and we're about to get into it, no cap.

🌸 NAME 🌸

netlabel_mgmt_selinux — the Security Enhanced Linux Policy for the netlabel_mgmt processes. Periodt. That's the whole vibe.

---

💖 DESCRIPTION 💖

Security-Enhanced Linux secures the netlabel_mgmt processes via flexible mandatory access control. Like, it's literally the bouncer at the club for your processes. 🫶

The netlabel_mgmt processes execute with the netlabel_mgmt_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 netlabel_mgmt_t

Go off, ps. Show me those contexts. 👑

---

🦋 ENTRYPOINTS 🦋

The netlabel_mgmt_t SELinux type can be entered via the netlabel_mgmt_exec_t file type.

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

/usr/bin/netlabelctl, /usr/bin/netlabel-config

Those are the doors into the domain, bestie. Iconic paths, honestly. ✨

---

💜 PROCESS TYPES 💜

SELinux defines process types (domains) for each process running on the system. Like every process gets its own little personality type. 🎀

You can see the context of a process using the -Z option to ps. It's giving "show me the receipts."

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

The following process types are defined for netlabel_mgmt:

netlabel_mgmt_t

Note: semanage permissive -a netlabel_mgmt_t can be used to make the process type netlabel_mgmt_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, it's not mad, it's just disappointed. 😭

---

🌈 BOOLEANS 🌈

SELinux policy is customizable based on least access required. netlabel_mgmt policy is extremely flexible and has several booleans that allow you to manipulate the policy and run netlabel_mgmt with the tightest access possible. Tightest access = main character energy, lowkey. 🔥

If you want to dontaudit all daemons scheduling requests (setsched, sys_nice), you must turn on the daemons_dontaudit_scheduling boolean. Enabled by default.

setsebool -P daemons_dontaudit_scheduling 1

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

Two booleans, both enabled by default. We love a consistent queen. 💅

---

🎀 MANAGED FILES 🎀

The SELinux process type netlabel_mgmt_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. Like, SELinux can't do everything, bestie. UID's gotta pull its weight too. 🙈

💖 cluster_conf_t

/etc/cluster(/.*)?

💖 cluster_var_lib_t

/var/lib/pcsd(/.*)?
/var/lib/cluster(/.*)?
/var/lib/openais(/.*)?
/var/lib/pengine(/.*)?
/var/lib/corosync(/.*)?
/usr/lib/heartbeat(/.*)?
/var/lib/heartbeat(/.*)?
/var/lib/pacemaker(/.*)?

💖 cluster_var_run_t

/run/crm(/.*)?
/run/cman_.*
/run/rsctmp(/.*)?
/run/aisexec.*
/run/heartbeat(/.*)?
/run/pcsd-ruby.socket
/run/corosync-qnetd(/.*)?
/run/corosync-qdevice(/.*)?
/run/pcsd.socket
/run/corosync.pid
/run/cpglockd.pid
/run/rgmanager.pid
/run/cluster/rgmanager.sk

💖 root_t

/sysroot/.aleph-version.json
/sysroot/ostree/deploy/.*-atomic/deploy(/.*)?
/
/initrd
/var/lib/ntp

That's the whole list. Every path accounted for, no skipping. Obsessed with how thorough this is. 🌸

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. Like a little name tag but for files. So cute. 🏷️

You can see the context of a file using the -Z option to ls.

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

⭐ STANDARD FILE CONTEXT

SELinux defines the file context types for the netlabel_mgmt, 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 netlabel_mgmt_exec_t '/srv/netlabel_mgmt/content(/.*)?'
restorecon -R -v /srv/mynetlabel_mgmt_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies stay winning. 💅

The following file types are defined for netlabel_mgmt:

🌟 netlabel_mgmt_exec_t

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

Paths:

/usr/bin/netlabelctl, /usr/bin/netlabel-config

🌟 netlabel_mgmt_unit_file_t

• Set files with the netlabel_mgmt_unit_file_t type, if you want to treat the files as netlabel mgmt unit content.

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 like, chcon is a quick little glow-up, but semanage fcontext + restorecon is the permanent makeover. Don't get it twisted. 😭

---

👑 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. For the besties who prefer a pretty interface. 💖

And that's the whole manual page, babe! It's the netlabel_mgmt version from 26-10-06, and honestly it's giving "secure and flexible" in the best way. Slay, SELinux. Slay. 💅✨
