From f1440a90465bea1993f937ac7add592ce1e4ff44 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Sat, 12 Apr 2025 13:16:43 +0800 Subject: crypto: api - Add support for duplicating algorithms before registration If the bit CRYPTO_ALG_DUP_FIRST is set, an algorithm will be duplicated by kmemdup before registration. This is inteded for hardware-based algorithms that may be unplugged at will. Do not use this if the algorithm data structure is embedded in a bigger data structure. Perform the duplication in the driver instead.
