Module kernel_config 

Features derived from compile-time kernel configuration

The Linux kernel accepts an assortment of flags that can be enabled or disabled at compilation. These configuration flags are used to determine which eBPF features are eventually available on the running kernel.

Depending on your distribution, your kernel config can be available in a number of locations such as:

• /proc/config.gz
• /boot/config
• /boot/config-$(uname -r)

This module will search for and read your kernel configuration for relevant eBPF flags. If you believe a flag is missing or incorrectly added to the set in KERNEL_CONFIG_KEYS, please file an issue.
