💖 kdump_dep_generator_selinux — SELinux Policy for kdump_dep_generator 💖

okay bestie, you're reading the kdump_d..._selinux(8) manual page, and it's all about the SELinux policy for the kdump_dep_generator processes. Let's get into it 💅✨

---

✨ NAME ✨

kdump_dep_generator_selinux — Security Enhanced Linux Policy for the kdump_dep_generator processes.

🦋 DESCRIPTION 🦋

Ngl, Security-Enhanced Linux secures the kdump_dep_generator processes via flexible mandatory access control. That's the whole vibe.

The kdump_dep_generator processes execute with the kdump_dep_generator_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 kdump_dep_generator_t

🎀 ENTRYPOINTS 🎀

The kdump_dep_generator_t SELinux type can be entered via the kdump_dep_generator_exec_t file type.

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

• /usr/lib/systemd/system-generators/kdump-dep-generator.sh

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

The following process types are defined for kdump_dep_generator:

• kdump_dep_generator_t

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

💜 BOOLEANS 💜

SELinux policy is customizable based on least access required. kdump_dep_generator policy is extremely flexible and has several booleans that allow you to manipulate the policy and run kdump_dep_generator 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. It is enabled by default.

setsebool -P fips_mode 1

🧚 MANAGED FILES 🧚

The SELinux process type kdump_dep_generator_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.

• kdump_dep_unit_file_t

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

🎀 STANDARD FILE CONTEXT 🎀

SELinux defines the file context types for the kdump_dep_generator, 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 kdump_dep_generator_exec_t '/srv/kdump_dep_generator/content(/.*)?'
restorecon -R -v /srv/mykdump_dep_generator_content

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

The following file types are defined for kdump_dep_generator:

• kdump_dep_generator_exec_t — Set files with the kdump_dep_generator_exec_t type, if you want to transition an executable to the kdump_dep_generator_t domain.
• kdump_dep_generator_unit_file_t — Set files with the kdump_dep_generator_unit_file_t type, if you want to treat the files as kdump dep generator unit content.

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. 🔥

⭐ 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.
