gnome_i..._selinux(8)

okay bestie, welcome to the gnome_i..._selinux(8) page — it’s the SELinux Policy gnome_initial_setup manual, and we’re gonna make it make sense. ✨

💖 NAME 💖

gnome_initial_setup_selinux — Security Enhanced Linux Policy for the gnome_initial_setup processes. 🫶

🦋 DESCRIPTION 🦋

Security-Enhanced Linux secures the gnome_initial_setup processes via flexible mandatory access control.

The gnome_initial_setup processes execute with the gnome_initial_setup_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 gnome_initial_setup_t

🌈 ENTRYPOINTS 🌈

The gnome_initial_setup_t SELinux type can be entered via the gnome_initial_setup_exec_t file type.

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

/usr/libexec/gnome-initial-setup.*

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

The following process types are defined for gnome_initial_setup:

• gnome_initial_setup_t

Note: semanage permissive -a gnome_initial_setup_t can be used to make the process type gnome_initial_setup_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. gnome_initial_setup policy is extremely flexible and has several booleans that allow you to manipulate the policy and run gnome_initial_setup with the tightest access possible.

• deny_execmem — if you want to deny user domains applications to map a memory region as both executable and writable, turn this on. This is dangerous and the executable should be reported in bugzilla. It’s 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, turn this on. It’s disabled by default.

setsebool -P mmap_low_allowed 1

• secure_mode_insmod — if you want to disable kernel module loading, turn this on. It’s disabled by default.

setsebool -P secure_mode_insmod 1

• selinuxuser_execheap — if you want to allow unconfined executables to make their heap memory executable, turn this on. 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. It’s disabled by default.

setsebool -P selinuxuser_execheap 1

• selinuxuser_execstack — if you want to allow unconfined executables to make their stack executable, turn this on. This should never, ever be necessary. Probably indicates a badly coded executable, but could indicate an attack. This executable should be reported in bugzilla. It’s disabled by default.

setsebool -P selinuxuser_execstack 1

🎀 MANAGED FILES 🎀

The SELinux process type gnome_initial_setup_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

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

🧚 STANDARD FILE CONTEXT 🧚

SELinux defines the file context types for the gnome_initial_setup. If you wanted to store files with these types in 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 gnome_initial_setup_exec_t
'/srv/gnome_initial_setup/content(/.*)?'
restorecon -R -v /srv/mygnome_initial_setup_content

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

The following file types are defined for gnome_initial_setup:

• gnome_initial_setup_exec_t — Set files with the gnome_initial_setup_exec_t type, if you want to transition an executable to the gnome_initial_setup_t domain. 🔥
• gnome_initial_setup_tmp_t — Set files with the gnome_initial_setup_tmp_t type, if you want to store gnome initial setup temporary files in the /tmp directories. 🍓
• gnome_initial_setup_var_lib_t — Set files with the gnome_initial_setup_var_lib_t type, if you want to store the gnome initial setup files under the /var/lib directory. 🦋
• gnome_initial_setup_var_run_t — Set files with the gnome_initial_setup_var_run_t type, if you want to store the gnome initial setup 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.

💅 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.
