- CONFIG_XFRM: This option enables the transformation framework for IPsec, which handles the encryption, authentication, and compression of IP packets. If you disable this option, you will not be able to use any IPsec protocol, such as ESP, AH, or IPComp. You will also not be able to use the ip xfrm command or the Netlink/XFRM interface to configure IPsec policies and keys1.
- CONFIG_INET_AH: This option enables the IP Authentication Header (AH) transformation for IPv4 packets. AH is a protocol that provides integrity and authentication for IP packets, but not confidentiality. If you disable this option, you will not be able to use AH for IPv4 packets. You will also disable the CONFIG_INET6_AH option, which enables AH for IPv6 packets1.
- CONFIG_INET_ESP: This option enables the IP Encapsulating Security Payload (ESP) transformation for IPv4 packets. ESP is a protocol that provides confidentiality, integrity, and authentication for IP packets. If you disable this option, you will not be able to use ESP for IPv4 packets. You will also disable the CONFIG_INET6_ESP option, which enables ESP for IPv6 packets1.
- CONFIG_INET_IPCOMP: This option enables the IP Compression Protocol (IPComp) transformation for IPv4 packets. IPComp is a protocol that provides compression for IP packets, which can reduce the bandwidth usage and improve the performance of network communications. If you disable this option, you will not be able to use IPComp for IPv4 packets. You will also disable the CONFIG_INET6_IPCOMP option, which enables IPComp for IPv6 packets1.
