✨ cdrecord_selinux ✨

Hey bestie! 💖 This is the cdrecord_selinux manual page, and it's literally all about the Security Enhanced Linux Policy for the cdrecord processes. No cap, it's giving secure vibes only. 🎀

---

🌸 NAME 🌸

cdrecord_selinux — Security Enhanced Linux Policy for the cdrecord processes. Periodt. 💅

---

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the cdrecord processes via flexible mandatory access control. It's like a VIP velvet rope for your processes, and SELinux is the bouncer. 👑

The cdrecord processes execute with the cdrecord_t SELinux type. You can check if you have these processes running by executing the ps command with the -Z qualifier. Super easy, barely an inconvenience. ✨

For example:

ps -eZ | grep cdrecord_t

---

🧚 ENTRYPOINTS 🧚

The cdrecord_t SELinux type can be entered via the cdrecord_exec_t file type. It's giving main character energy — this is the doorway. 🚪✨

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

• /usr/bin/wodim
• /usr/bin/cdrecord
• /usr/bin/growisofs

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. It's a whole vibe. 🌈

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

Policy governs the access confined processes have to files. SELinux cdrecord policy is very flexible, allowing users to setup their cdrecord processes in as secure a method as possible. Obsessed with the flexibility, honestly. 🫶

The following process types are defined for cdrecord:

• cdrecord_t

Note: semanage permissive -a cdrecord_t can be used to make the process type cdrecord_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. So it's still snitching, fr fr. 💀

---

🍓 BOOLEANS 🍓

SELinux policy is customizable based on least access required. cdrecord policy is extremely flexible and has several booleans that allow you to manipulate the policy and run cdrecord with the tightest access possible. Slay. 💖

If you want to determine whether cdrecord can read various content — nfs, samba, removable devices, user temp and untrusted content files — you must turn on the cdrecord_read_content boolean. Disabled by default.

setsebool -P cdrecord_read_content 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 support NFS home directories, you must turn on the use_nfs_home_dirs boolean. Enabled by default.

setsebool -P use_nfs_home_dirs 1

If you want to support SAMBA home directories, you must turn on the use_samba_home_dirs boolean. Disabled by default.

setsebool -P use_samba_home_dirs 1

---

🌺 MANAGED FILES 🌺

The SELinux process type cdrecord_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. Don't forget the basics, bestie. 🔑

• cifs_t — no paths listed, it's just vibing. ☁️
• ecryptfs_t — paths:

/home/[^/]+/.Private(/.*)?
/home/[^/]+/.ecryptfs(/.*)?

• fusefs_t — path:

/run/user/[0-9]+/gvfs

• nfs_t — no paths listed, living its best life. 🌈

---

🎀 FILE CONTEXTS 🎀

SELinux requires files to have an extended attribute to define the file type. It's like a name tag but for files. 🏷️

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

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the cdrecord. 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. Do it for the plot. 📝

semanage fcontext -a -t cdrecord_exec_t '/srv/cdrecord/content(/.*)?'
restorecon -R -v /srv/mycdrecord_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex is that girl. 💁‍♀️

The following file types are defined for cdrecord:

• cdrecord_exec_t — set files with the cdrecord_exec_t type if you want to transition an executable to the cdrecord_t domain. Paths:

/usr/bin/wodim, /usr/bin/cdrecord, /usr/bin/growisofs

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. Permanent > temporary, always. 😌

---

🫶 COMMANDS 🫶

semanage fcontext can also be used to manipulate default file context mappings. Slay. ✨

semanage permissive can also be used to manipulate whether or not a process type is permissive. Permission granted, bestie. 💅

semanage module can also be used to enable/disable/install/remove policy modules. Modular realness. 🧩

semanage boolean can also be used to manipulate the booleans. Boolean baddie. 🎀

system-config-selinux is a GUI tool available to customize SELinux policy settings. For when you want to point and click instead of type. 🖱️✨
