🌸 NAME 🌸

boinc_project_selinux — Security Enhanced Linux Policy for the boinc_project processes. Okay bestie, you're reading boinc_project_selinux(8), the page for the SELinux Policy boinc_project, and it's giving very specific security-nerd realness 💅✨

✨ DESCRIPTION ✨

Security-Enhanced Linux secures the boinc_project processes via flexible mandatory access control. No cap, that's the whole vibe.

The boinc_project processes execute with the boinc_project_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 boinc_project_t

🚪 ENTRYPOINTS 🚪

The boinc_project_t SELinux type can be entered via the boinc_project_var_lib_t file type. That's the doorway, bestie 🚪✨

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

/var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?

👯 PROCESS TYPES 👯

SELinux defines process types (domains) for each process running on the system. Yep, every process gets its own little domain outfit 👑

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

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

The following process types are defined for boinc_project:

• boinc_project_t

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

🔘 BOOLEANS 🔘

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

• deny_execmem — 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

• mmap_low_allowed — 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

• secure_mode_insmod — 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

• selinuxuser_execheap — 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

📁 MANAGED FILES 📁

The SELinux process type boinc_project_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. All of them. Iconic scope, honestly 🌈

🏷️ FILE CONTEXTS 🏷️

SELinux requires files to have an extended attribute to define the file type. Label checks are literally part of the whole thing, bestie.

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

💅 STANDARD FILE CONTEXT 💅

SELinux defines the file context types for the boinc_project. 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 boinc_project_tmp_t
'/srv/boinc_project/content(/.*)?'
restorecon -R -v /srv/myboinc_project_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. Regex girlies stay winning 🧚✨

The following file types are defined for boinc_project:

• boinc_project_tmp_t — set files with the boinc_project_tmp_t type if you want to store boinc project temporary files in the /tmp directories.
• boinc_project_var_lib_t — set files with the boinc_project_var_lib_t type if you want to store the boinc project files under the /var/lib directory.

Paths: /var/lib/boinc/slots(/.*)?, /var/lib/boinc/projects(/.*)?

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 labels are cute but not forever, iykyk 💀💖

🛠️ 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.
