iwhd_selinux — the SELinux glow-up for iwhd 💅✨

Okay bestie, so this is the manual for iwhd_selinux, which is literally the SELinux policy page for the iwhd processes. Think of it as the security vibe check for iwhd, and we're gonna go through it together. Stay with me, it's giving "mandatory access control but make it fashion" 🎀

---

NAME ✨

iwhd_selinux — Security Enhanced Linux Policy for the iwhd processes. No cap, that's the whole vibe. 🫶

---

DESCRIPTION 🌸

Security-Enhanced Linux secures the iwhd processes via flexible mandatory access control. It's giving "we're protected but make it customizable" energy.

The iwhd processes execute with the iwhd_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. Obsessed with a good -Z flag honestly.

For example:

ps -eZ | grep iwhd_t

---

ENTRYPOINTS 🚪💖

The iwhd_t SELinux type can be entered via the iwhd_exec_t file type. Literally the doorway, the main character entrance.

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

/usr/bin/iwhd

That's it, that's the path. Iconic and to the point. ✨

---

PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. Lowkey a whole taxonomy moment.

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

Policy governs the access confined processes have to files. SELinux iwhd policy is very flexible, allowing users to setup their iwhd processes in as secure a method as possible. Slay, security slay. 🔥

The following process types are defined for iwhd:

• iwhd_t

Note: semanage permissive -a iwhd_t can be used to make the process type iwhd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So like, it's chill but it's still watching you, iykyk. 👀

---

BOOLEANS 🎛️💖

SELinux policy is customizable based on least access required. iwhd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run iwhd with the tightest access possible. We love a customizable icon. ✨

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

---

MANAGED FILES 📁🦋

The SELinux process type iwhd_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. Note: the process's UID still needs to have DAC permissions, so like, SELinux isn't doing everything for you bestie. 🙈

FILE CONTEXTS 🏷️🌈

SELinux requires files to have an extended attribute to define the file type. Fancy, right? ✨

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 iwhd policy is very flexible allowing users to setup their iwhd processes in as secure a method as possible. (Yes bestie, they said it twice, it's that flexible. 💅)

STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the iwhd. 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. It's a whole two-step, but it slays.

semanage fcontext -a -t iwhd_exec_t '/srv/iwhd/content(/.*)?'
restorecon -R -v /srv/myiwhd_content

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

The following file types are defined for iwhd:

• iwhd_exec_t — Set files with the iwhd_exec_t type, if you want to transition an executable to the iwhd_t domain.
• iwhd_initrc_exec_t — Set files with the iwhd_initrc_exec_t type, if you want to transition an executable to the iwhd_initrc_t domain.
• iwhd_log_t — Set files with the iwhd_log_t type, if you want to treat the data as iwhd log data, usually stored under the /var/log directory.
• iwhd_var_lib_t — Set files with the iwhd_var_lib_t type, if you want to store the iwhd files under the /var/lib directory.
• iwhd_var_run_t — Set files with the iwhd_var_run_t type, if you want to store the iwhd 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. Don't forget the restorecon bestie, or it's not gonna stick. 😭

---

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 girlies who prefer a little visual moment. 🖥️✨

Okay that's the whole page bestie, you ate that. This was iwhd from 26-10-06, manual version iwhd_selinux(8) — go forth and be secure, mwah! 💋✨🎀
