qmail_clean_selinux(8)

🎀 qmail_clean_selinux(8) 🎀

okay so bestie, welcome to the qmail_clean_selinux manual page — this is the SELinux Policy qmail_clean situation, and we're gonna make it make sense. 💅

💖 NAME 💖

qmail_clean_selinux — Security Enhanced Linux Policy for the qmail_clean processes. That's the whole name vibe: this page is the qmail_clean_selinux(8) manual, no cap. ✨

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the qmail_clean processes via flexible mandatory access control. It's giving mandatory access control but make it flexible, and honestly? iconic. 💖

The qmail_clean processes execute with the qmail_clean_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 qmail_clean_t

🦋 ENTRYPOINTS 🦋

The qmail_clean_t SELinux type can be entered via the qmail_clean_exec_t file type. That's the doorway, bestie. 🚪✨

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

/var/qmail/bin/qmail-clean

👑 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 qmail_clean policy is very flexible allowing users to setup their qmail_clean processes in as secure a method as possible. Flexible but secure? We love a balanced queen. 💜

The following process types are defined for qmail_clean:

• qmail_clean_t

Note: semanage permissive -a qmail_clean_t can be used to make the process type qmail_clean_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, permissive ≠ invisible — the receipts still show up. 🧾👀

✨ BOOLEANS ✨

SELinux policy is customizable based on least access required. qmail_clean policy is extremely flexible and has several booleans that allow you to manipulate the policy and run qmail_clean with the tightest access possible. Tightest access? The vibe is "least privilege but make it couture." 💅

If you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. Slay, it's already on by default. ✅

setsebool -P fips_mode 1

🎀 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. 👀

Policy governs the access confined processes have to these files. SELinux qmail_clean policy is very flexible allowing users to setup their qmail_clean processes in as secure a method as possible. Same energy as before: flexible, but secure. 🫶

🌈 STANDARD FILE CONTEXT 🌈

SELinux defines the file context types for the qmail_clean, if you wanted to store files with these types in different paths, you need to execute the semanage command to specify alternate labeling and then use restorecon to put the labels on disk. Labeling era. 🏷️✨

semanage fcontext -a -t qmail_clean_exec_t
'/srv/qmail_clean/content(/.*)?'

restorecon -R -v /srv/myqmail_clean_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies rise. 🧚

The following file types are defined for qmail_clean:

• qmail_clean_exec_t — set files with the qmail_clean_exec_t type, if you want to transition an executable to the qmail_clean_t domain. Domain transition? We love a glow-up. 🌟

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. Temporary vs permanent — choose your fighter, but the permanent one updates the database. 💾💅

🛠️ 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. GUI bestie, for when you want buttons. 🖱️✨
