💖 piranha_web_selinux(8) — the girlies' guide to SELinux Policy piranha_web 💖

okay so bestie, welcome to piranha_web_selinux(8), the manual page for SELinux Policy piranha_web. this is literally the page you want if you're messing with piranha_web and SELinux is being A Whole Thing. let's get into it 🫶

✨ NAME ✨

piranha_web_selinux — the Security Enhanced Linux Policy for the piranha_web processes. that's it, that's the vibe 💅

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the piranha_web processes via flexible mandatory access control. mandatory!! she's not asking, she's telling ✨

The piranha_web processes execute with the piranha_web_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 piranha_web_t

like, run it, see what shows up, we love a quick vibe check 👑

🦋 ENTRYPOINTS 🦋

The piranha_web_t SELinux type can be entered via the piranha_web_exec_t file type.

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

/usr/sbin/piranha_gui

that's the one door in, bestie 🚪✨

🎀 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 piranha_web policy is very flexible, allowing users to setup their piranha_web processes in as secure a method as possible.

The following process types are defined for piranha_web:

  • piranha_web_t
Note: semanage permissive -a piranha_web_t can be used to make the process type piranha_web_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, she stops blocking you but she's still taking notes 📝😭

💜 BOOLEANS 💜

SELinux policy is customizable based on least access required. piranha_web policy is extremely flexible and has several booleans that allow you to manipulate the policy and run piranha_web with the tightest access possible. tightest access = the most slay security ✨

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. (so you gotta actually flip this one, she's off out of the box 🙈)

setsebool -P nis_enabled 1

💖 MANAGED FILES 💖

The SELinux process type piranha_web_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. yes, both. SELinux isn't out here doing DAC's homework 💀

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

🌟 EQUIVALENCE DIRECTORIES 🌟

piranha_web policy stores data with multiple different file context types under the /var/lib/luci directory. If you would like to store the data in a different directory you can use the semanage command to create an equivalence mapping. If you wanted to store this data under the /srv directory you would execute the following command:

semanage fcontext -a -e /var/lib/luci /srv/luci
restorecon -R -v /srv/luci

see, you're just telling SELinux "hey, this spot is literally the same vibe as that spot" 🫶

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the piranha_web, 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 piranha_web_tmp_t '/srv/mypiranha_web_content(/.*)?'
restorecon -R -v /srv/mypiranha_web_content
Note: SELinux often uses regular expressions to specify labels that match multiple files. regex girlies rise 🧚✨

The following file types are defined for piranha_web:

piranha_web_conf_t

  • Set files with the piranha_web_conf_t type, if you want to treat the files as piranha web configuration data, usually stored under the /etc directory.

Paths:

/var/lib/luci/etc(/.*)?, /var/lib/luci/cert(/.*)?

piranha_web_data_t

  • Set files with the piranha_web_data_t type, if you want to treat the files as piranha web content.

piranha_web_exec_t

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

piranha_web_tmp_t

  • Set files with the piranha_web_tmp_t type, if you want to store piranha web temporary files in the /tmp directories.

piranha_web_tmpfs_t

  • Set files with the piranha_web_tmpfs_t type, if you want to store piranha web files on a tmpfs file system.

piranha_web_var_run_t

  • Set files with the piranha_web_var_run_t type, if you want to store the piranha web 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 = chcon, permanent = semanage fcontext + restorecon. write it down bestie 📝💅

⭐ 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 you simply cannot with the terminal today 😌
