Normalize CFI tags for integers
configname: CONFIG_CFI_ICALL_NORMALIZE_INTEGERS
Linux Kernel Configuration
└─>General architecture-dependent options
└─>Normalize CFI tags for integers
In linux kernel since version 6.1.112 (release Date: 2024-09-30)
This option normalizes the CFI tags for integer types so that all
integer types of the same size and signedness receive the same CFI
tag.
The option is separate from CONFIG_RUST because it affects the ABI.
When working with build systems that care about the ABI, it is
convenient to be able to turn on this flag first, before Rust is
turned on.
This option is necessary for using CFI with Rust. If unsure, say N.
