hostapd_selinux(8)

✨ hostapd_selinux(8) ✨

okay bestie, this is the hostapd_selinux page — it's the SELinux policy rundown for hostapd processes, from the SELinux Policy hostapd gang. it's giving "niche but iconic" and honestly it ate 💅

---

🌸 NAME 🌸

hostapd_selinux — Security Enhanced Linux Policy for the hostapd processes 🫶

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the hostapd processes via flexible mandatory access control. no cap, that's the whole vibe — SELinux is the bouncer and hostapd is the guest list ✨

The hostapd processes execute with the hostapd_t SELinux type. wanna check if you've got these processes running? just run the ps command with the -Z qualifier. super easy, literally.

For example:

ps -eZ | grep hostapd_t

---

🎀 ENTRYPOINTS 🎀

The hostapd_t SELinux type can be entered via the hostapd_exec_t file type. that's the door, bestie 🚪

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

/usr/bin/hostapd

---

⭐ PROCESS TYPES ⭐

SELinux defines process types (domains) for each process running on the system. yes, every single one gets its own little label, main character energy for everyone 🌈

You can see the context of a process using the -Z option to ps. do it, it's fun.

Policy governs the access confined processes have to files. SELinux hostapd policy is very flexible, allowing users to setup their hostapd processes in as secure a method as possible. tightest access possible? yes ma'am 🔥

The following process types are defined for hostapd:

• hostapd_t

Note: semanage permissive -a hostapd_t can be used to make the process type hostapd_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 stuff but it's still gonna text you about it 😭

---

💖 BOOLEANS 💖

SELinux policy is customizable based on least access required. hostapd policy is extremely flexible and has several booleans that allow you to manipulate the policy and run hostapd with the tightest access possible. booleans are literally the switches of the SELinux world, obsessed 🎚️

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

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

🧚 MANAGED FILES 🧚

The SELinux process type hostapd_t can manage files labeled with the following file types. The paths listed are the default paths for these file types. heads up though — the processes UID still need to have DAC permissions. SELinux is not out here overriding DAC, no ma'am 💀

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type. every file's gotta have its label, that's just the rules 📛

You can see the context of a file using the -Z option to ls. (yes, -Z again. it's the moment.)

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

🍓 STANDARD FILE CONTEXT 🍓

SELinux defines the file context types for the hostapd, 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. like: relabel era ✨

semanage fcontext -a -t hostapd_exec_t '/srv/hostapd/content(/.*)?'
restorecon -R -v /srv/myhostapd_content

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

The following file types are defined for hostapd:

• hostapd_exec_t — Set files with the hostapd_exec_t type, if you want to transition an executable to the hostapd_t domain.
• hostapd_tmp_t — Set files with the hostapd_tmp_t type, if you want to store hostapd temporary files in the /tmp directories.
• hostapd_unit_file_t — Set files with the hostapd_unit_file_t type, if you want to treat the files as hostapd unit content.
• hostapd_var_run_t — Set files with the hostapd_var_run_t type, if you want to store the hostapd 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. temporary vs permanent, bestie — know the difference or you're gonna have a bad time 😭

🌈 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 whole GUI! for the clicky girlies 💅)
