From 439963cdc3aa447dfd3b5abc05fcd25cef4d22dc Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sun, 16 Feb 2025 11:07:22 +0800 Subject: crypto: ahash - Add virtual address support This patch adds virtual address support to ahash. Virtual addresses were previously only supported through shash. The user may choose to use virtual addresses with ahash by calling ahash_request_set_virt instead of ahash_request_set_crypt. The API will take care of translating this to an SG list if necessary, unless the algorithm declares that it supports chaining. Therefore in order for an ahash algorithm to support chaining, it must also support virtual addresses directly.
