From 633439f5b7e9e2a88fb2ead38bc12c5061897cf2 Mon Sep 17 00:00:00 2001 From: Herbert Xu Date: Thu, 6 Apr 2017 16:16:10 +0800 Subject: [PATCH] xfrm: Prepare for CRYPTO_MAX_ALG_NAME expansion This patch fixes the xfrm_user code to use the actual array size rather than the hard-coded CRYPTO_MAX_ALG_NAME length. This is because the array size is fixed at 64 bytes while we want to increase the in-kernel CRYPTO_MAX_ALG_NAME value.
