💅 mojomojo_script_selinux — like, the whole vibe

okay so real talk, this is the manual page for mojomojo...t_selinux(8) — yes that's the title, no I didn't make it up — and it's all about the SELinux policy for the mojomojo_script processes. grab a snack, we're getting into it 🍓

✨ NAME ✨

mojomojo_script_selinux — Security Enhanced Linux Policy for the mojomojo_script processes. that's the whole thing. iconic of it honestly 👑

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the mojomojo_script processes via flexible mandatory access control. like, SELinux is the friend who checks your outfit before you leave the house, except the outfit is syscalls 💅

The mojomojo_script processes execute with the mojomojo_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 mojomojo_script_t

run that, bestie, and you'll see them 👀

🌸 ENTRYPOINTS 🌸

The mojomojo_script_t SELinux type can be entered via the mojomojo_script_exec_t file type.

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

/usr/bin/mojomojo_fastcgi.pl

that's the one door in. literally the only one fr fr 🚪

👑 PROCESS TYPES 👑

SELinux defines process types (domains) for each process running on the system

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

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

The following process types are defined for mojomojo_script:

  • mojomojo_script_t
Note: semanage permissive -a mojomojo_script_t can be used to make the process type mojomojo_script_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated.

ok so permissive mode = it stops blocking you but it's still gonna talk about you in the logs 😭 the AVC messages are still generated, no cap.

🔥 BOOLEANS 🔥

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

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 httpd cgi support, you must turn on the httpd_enable_cgi boolean. Enabled by default.

setsebool -P httpd_enable_cgi 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

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

setsebool -P nscd_use_shm 1

the -P is the "make it permanent bestie" flag, don't forget it or you'll be doing this again after a reboot 🙈

🎀 MANAGED FILES 🎀

The SELinux process type mojomojo_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.

  • mojomojo_rw_content_t
    • /var/lib/mojomojo(/.*)?
  • mojomojo_tmp_t

that's it, those are the two. mojomojo_tmp_t has no default paths listed, so don't come for me, that's just what the page says 💀

heads up: DAC permissions are still a whole separate thing. SELinux being chill about it does not mean your UID is chill about it.

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

⭐ STANDARD FILE CONTEXT ⭐

SELinux defines the file context types for the mojomojo_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 mojomojo_script_exec_t '/srv/mojomojo_script/content(/.*)?'
restorecon -R -v /srv/mymojomojo_script_content

yes, those two paths are different in the example, and yes, I'm copying them exactly as written. that's the bit. don't @ me 😭

Note: SELinux often uses regular expressions to specify labels that match multiple files.

The following file types are defined for mojomojo_script:

  • mojomojo_script_exec_t — Set files with the mojomojo_script_exec_t type, if you want to transition an executable to the mojomojo_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.

so chcon = temporary glow-up, semanage fcontext = actual commitment, restorecon = applying the labels for real. got it? got it 💖

💜 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 when the terminal is giving too much and you want buttons 🫶
