✨ virtnetworkd_selinux(8) — the SELinux glow-up for virtnetworkd ✨

okay so bestie, this is the virtnetworkd_selinux(8) page from the SELinux Policy virtnetworkd manual. it's giving "how to keep your virtnetworkd processes secure and cute" and honestly? we're obsessed. 💖

🎀 NAME 🎀

virtnetworkd_selinux — Security Enhanced Linux Policy for the virtnetworkd processes. no cap, that's the whole vibe.

🌸 DESCRIPTION 🌸

Security-Enhanced Linux secures the virtnetworkd processes via flexible mandatory access control. it's literally the bodyguard of your daemons, periodt. 💅

The virtnetworkd processes execute with the virtnetworkd_t SELinux type. you can check if you have these processes running by executing the ps command with the -Z qualifier. it's giving "who dis" but for processes.

for example:

ps -eZ | grep virtnetworkd_t

🦋 ENTRYPOINTS 🦋

The virtnetworkd_t SELinux type can be entered via the virtnetworkd_exec_t file type. main character energy only.

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

/usr/bin/virtnetworkd

✨ PROCESS TYPES ✨

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

You can see the context of a process using the -Z option to ps. it's like a vibe check for your processes.

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

The following process types are defined for virtnetworkd:

virtnetworkd_t

Note: semanage permissive -a virtnetworkd_t can be used to make the process type virtnetworkd_t permissive. SELinux does not deny access to permissive process types, but the AVC (SELinux denials) messages are still generated. so like, it's chill but it still snitches. 😭

🔥 BOOLEANS 🔥

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

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 virt daemons run unconfined hooks, you must turn on the virt_hooks_unconfined boolean. Disabled by default.

setsebool -P virt_hooks_unconfined 1

🌈 MANAGED FILES 🌈

The SELinux process type virtnetworkd_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. no skipping the UID bestie, that's not very slay of you.

• cluster_conf_t

/etc/cluster(/.*)?

💜 FILE CONTEXTS 💜

SELinux requires files to have an extended attribute to define the file type. it's like giving every file its own little name tag. 🏷️

You can see the context of a file using the -Z option to ls. go ahead, check the vibes.

Policy governs the access confined processes have to these files. SELinux virtnetworkd policy is very flexible allowing users to setup their virtnetworkd processes in as secure a method as possible. flexible and secure? we love to see it.

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the virtnetworkd, 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. it's giving "customize your own adventure".

semanage fcontext -a -t virtnetworkd_var_run_t '/srv/virtnetworkd/content(/.*)?'
restorecon -R -v /srv/myvirtnetworkd_content

Note: SELinux often uses regular expressions to specify labels that match multiple files. regex is that girl fr fr.

The following file types are defined for virtnetworkd:

• virtnetworkd_exec_t — Set files with the virtnetworkd_exec_t type, if you want to transition an executable to the virtnetworkd_t domain. it's literally the entrypoint, the main event.
• virtnetworkd_t — Set files with the virtnetworkd_t type, if you want to treat the files as virtnetworkd data. data? iconic.
• virtnetworkd_var_run_t — Set files with the virtnetworkd_var_run_t type, if you want to store the virtnetworkd files under the /run or /var/run directory.

Paths: /run/virtnetworkd.pid, /run/libvirt/virtnetworkd-sock, /run/libvirt/virtnetworkd-sock-ro, /run/libvirt/virtnetworkd-admin-sock

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 vs permanent = a whole mood. choose wisely bestie.

🫶 COMMANDS 🫶

semanage fcontext can also be used to manipulate default file context mappings. mapping queen.

semanage permissive can also be used to manipulate whether or not a process type is permissive. the vibes controller.

semanage module can also be used to enable/disable/install/remove policy modules. modular icon behavior.

semanage boolean can also be used to manipulate the booleans. booleans are the little switches of joy.

system-config-selinux is a GUI tool available to customize SELinux policy settings. for when you want the clicky-clicky experience.

okay that's the whole page bestie, no cap. this was virtnetworkd_selinux(8) from the SELinux Policy virtnetworkd manual, version 26-10-06. now go forth and secure those processes, you icon. 💖✨🎀
