config WIREGUARD tristate "IP: WireGuard secure network tunnel" depends on NET && INET select NET_UDP_TUNNEL select CRYPTO_BLKCIPHER select NEON select KERNEL_MODE_NEON default m ---help--- WireGuard is a secure, fast, and easy to use replacement for IPSec that uses modern cryptography and clever networking tricks. It's designed to be fairly general purpose and abstract enough to fit most use cases, while at the same time remaining extremely simple to configure. See www.wireguard.io for more info. It's safe to say Y or M here, as the driver is very lightweight and is only in use when an administrator chooses to add an interface. config WIREGUARD_PARALLEL bool "Enable parallel engine" depends on SMP && WIREGUARD select PADATA default y ---help--- This will allow WireGuard to utilize all CPU cores when encrypting and decrypting packets. It's safe to say Y here, and you probably should, as the performance improvements are substantial. config WIREGUARD_DEBUG bool "Debugging checks and verbose messages" depends on WIREGUARD ---help--- This will write log messages for handshake and other events that occur for a WireGuard interface. It will also perform some extra validation checks and unit tests at various points. This is only useful for debugging. Say N here unless you know what you're doing.
