SYSLOGD_UNCONFINED_SCRIPT_SELINUX(8)

💅 syslogd_unconfined_script_selinux — SELinux Policy for the syslogd_unconfined_script processes 🎀

okay bestie, welcome to the syslog...selinux(8) era — this is the SELinux policy manual for the syslogd_unconfined_script processes, and yes it's giving very "auto-generated but make it fashion." Let's get into it 💖

---

✨ NAME ✨

syslogd_unconfined_script_selinux — the Security Enhanced Linux Policy for the syslogd_unconfined_script processes. that's the whole name, she's long but she's iconic 🫶

---

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the syslogd_unconfined_script processes via flexible mandatory access control. literally the whole vibe — MAC but make it flexible ✨

The syslogd_unconfined_script processes execute with the syslogd_unconfined_script_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 syslogd_unconfined_script_t

go off, grep 👑

---

🦋 ENTRYPOINTS 🦋

The syslogd_unconfined_script_t SELinux type can be entered via the syslogd_unconfined_script_exec_t file type.

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

/usr/libexec/rsyslog(/.*)?

that regex ate, no cap 💅

---

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system. lowkey the whole system is just domains all the way down 😭

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

Policy governs the access confined processes have to files. SELinux syslogd_unconfined_script policy is very flexible allowing users to setup their syslogd_unconfined_script processes in as secure a method as possible. flexible AND secure? she contains multitudes 🧚

The following process types are defined for syslogd_unconfined_script:

• syslogd_unconfined_script_t

Note: semanage permissive -a syslogd_unconfined_script_t can be used to make the process type syslogd_unconfined_script_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like… she won't block you, but she WILL be watching and taking notes 🙈

---

🔥 BOOLEANS 🔥

SELinux policy is customizable based on least access required. syslogd_unconfined_script policy is extremely flexible and has several booleans that allow you to manipulate the policy and run syslogd_unconfined_script with the tightest access possible. tightest access possible = main character energy fr fr ⭐

If you want to deny user domains applications to map a memory region as both executable and writable, this is dangerous and the executable should be reported in bugzilla, you must turn on the deny_execmem boolean. Disabled by default.

setsebool -P deny_execmem 1

⚠️ bestie this one's literally labeled dangerous — report that executable in bugzilla, don't just vibe with it 💀

If you want to control the ability to mmap a low area of the address space, as configured by /proc/sys/vm/mmap_min_addr, you must turn on the mmap_low_allowed boolean. Disabled by default.

setsebool -P mmap_low_allowed 1

If you want to disable kernel module loading, you must turn on the secure_mode_insmod boolean. Disabled by default.

setsebool -P secure_mode_insmod 1

If you want to allow unconfined executables to make their heap memory executable. Doing this is a really bad idea. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execheap boolean. Disabled by default.

setsebool -P selinuxuser_execheap 1

🍓 "really bad idea" is the manpage's own words, I'm just the messenger. executable heap = yikes.

If you want to allow unconfined executables to make their stack executable. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla, you must turn on the selinuxuser_execstack boolean. Disabled by default.

setsebool -P selinuxuser_execstack 1

💀 "never, ever be necessary" — the double ever is doing so much emotional labor here. bugzilla. go.

🌈 MANAGED FILES 🌈

The SELinux process type syslogd_unconfined_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.

🎀 file_type

• all files on the system

yeah. ALL of them. she's not subtle 😭

---

💜 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 syslogd_unconfined_script policy is very flexible allowing users to setup their syslogd_unconfined_script processes in as secure a method as possible.

🌸 STANDARD FILE CONTEXT 🌸

SELinux defines the file context types for the syslogd_unconfined_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.

semanage fcontext -a -t syslogd_unconfined_script_exec_t '/srv/syslogd_unconfined_script/content(/.*)?'
restorecon -R -v /srv/mysyslogd_unconfined_script_content

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

The following file types are defined for syslogd_unconfined_script:

syslogd_unconfined_script_exec_t

• Set files with the syslogd_unconfined_script_exec_t type, if you want to transition an executable to the syslogd_unconfined_script_t domain.

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 chcon = a quick little glow-up; permanent = commit to the database, periodt 💅

---

⭐ 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.

the semanage girlies are carrying this entire section ngl 🫶
