💅 squid_script_selinux(8) — the manual page for squid_script_selinux 🦋

okay so bestie, this is the manual page for squid_script_selinux(8) — the SELinux policy for squid_script processes — and it's about to be your new hyperfixation fr fr.

---

✨ NAME ✨

squid_script_selinux — Security Enhanced Linux Policy for the squid_script processes 🎀

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the squid_script processes via flexible mandatory access control. like, it's giving strict-but-fair parent energy.

The squid_script processes execute with the squid_script_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. vibe check time, bestie:

ps -eZ | grep squid_script_t

---

🦋 ENTRYPOINTS 🦋

The squid_script_t SELinux type can be entered via the squid_script_exec_t file type. that's the VIP guest list, no cap.

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

/usr/share/lightsquid/cgi(/.*)?, /usr/lib/squid/cachemgr.cgi

---

💅 PROCESS TYPES 💅

SELinux defines process types (domains) for each process running on the system. it's a whole thing, iykyk.

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

Policy governs the access confined processes have to files. SELinux squid_script policy is very flexible allowing users to setup their squid_script processes in as secure a method as possible. flexible AND secure? main character energy honestly.

The following process types are defined for squid_script:

squid_script_t

Note: semanage permissive -a squid_script_t can be used to make the process type squid_script_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 👀

---

🔥 BOOLEANS 🔥

SELinux policy is customizable based on least access required — bare minimum vibes only. squid_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run squid_script with the tightest access possible. obsessed.

• fips_mode — if you want to allow all domains to execute in fips_mode, you must turn on the fips_mode boolean. Enabled by default. slay.

setsebool -P fips_mode 1

• httpd_enable_cgi — if you want to allow httpd cgi support, you must turn on the httpd_enable_cgi boolean. Enabled by default. iconic.

setsebool -P httpd_enable_cgi 1

• nis_enabled — if you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default. lowkey off until you say otherwise.

setsebool -P nis_enabled 1

• nscd_use_shm — if you want to allow confined applications to use nscd shared memory, you must turn on the nscd_use_shm boolean. Enabled by default. ate.

setsebool -P nscd_use_shm 1

---

🎀 MANAGED FILES 🎀

The SELinux process type squid_script_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 — don't forget the basics bestie.

squid_rw_content_t

---

🧚 FILE CONTEXTS 🧚

SELinux requires files to have an extended attribute to define the file type. it's literally metadata with commitment issues.

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 squid_script policy is very flexible allowing users to setup their squid_script processes in as secure a method as possible. we love a flexible icon.

🌈 STANDARD FILE CONTEXT 🌈

SELinux defines the file context types for the squid_script, 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. glow-up for your file paths:

semanage fcontext -a -t squid_script_exec_t
'/srv/squid_script/content(/.*)?'
restorecon -R -v /srv/mysquid_script_content

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

The following file types are defined for squid_script:

• squid_script_exec_t — Set files with the squid_script_exec_t type, if you want to transition an executable to the squid_script_t domain.

Paths: /usr/share/lightsquid/cgi(/.*)?, /usr/lib/squid/cachemgr.cgi

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 wisely bestie 💀

⭐ COMMANDS ⭐

怒火 no wait, actual commands lmao:

• 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 us? periodt.

and that's the tea bestie 🍓 this baby is from squid_script — version dated 26-10-06 — and it's the squid_script_selinux(8) manual, so go forth and SELinux responsibly. bye byeee 👋💜
