ifconfig_selinux(8)

🌸 NAME 🌸

okay bestie, welcome to ifconfig_selinux(8) — aka the SELinux Policy ifconfig page, aka the Security Enhanced Linux Policy for the ifconfig processes. 💖

✨ DESCRIPTION ✨

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

The ifconfig processes execute with the ifconfig_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 ifconfig_t

🚪 ENTRYPOINTS 🚪

The ifconfig_t SELinux type can be entered via the ifconfig_exec_t file type.

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

/usr/bin/ip, /usr/bin/iw, /usr/bin/tc, /usr/bin/ethtool,
/usr/bin/ifconfig, /usr/bin/iwconfig, /usr/bin/mii-tool,
/usr/bin/ipx_configure, /usr/bin/ipx_interface,
/usr/bin/ipx_internal_net

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

The following process types are defined for ifconfig:

• ifconfig_t

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

fips_mode

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

nis_enabled

If you want to allow system to run with NIS, you must turn on the nis_enabled boolean. Disabled by default.

setsebool -P nis_enabled 1

🗂️ MANAGED FILES 🗂️

The SELinux process type ifconfig_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.

ifconfig_var_run_t

/var/log/pluto.log.*

ipsec_var_run_t

/run/pluto(/.*)?
/run/charon.*
/var/racoon(/.*)?
/run/strongswan(/.*)?
/run/racoon.pid
/run/charon.ctl
/run/charon.dck
/run/charon.vici

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

🌟 STANDARD FILE CONTEXT 🌟

SELinux defines the file context types for the ifconfig. 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 ifconfig_exec_t '/srv/ifconfig/content(/.*)?'
restorecon -R -v /srv/myifconfig_content

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

The following file types are defined for ifconfig:

ifconfig_exec_t

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

Paths:

/usr/bin/ip, /usr/bin/iw, /usr/bin/tc, /usr/bin/ethtool,
/usr/bin/ifconfig, /usr/bin/iwconfig, /usr/bin/mii-tool,
/usr/bin/ipx_configure, /usr/bin/ipx_interface,
/usr/bin/ipx_internal_net

ifconfig_var_run_t

• Set files with the ifconfig_var_run_t type, if you want to store the ifconfig 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.
