From ab2ed0171a50ddee8390f472bb83f60d393b4b04 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Sun, 17 Apr 2016 11:19:55 +0200 Subject: [PATCH] macsec: fix crypto Kconfig dependency The new MACsec driver uses the AES crypto algorithm, but can be configured even if CONFIG_CRYPTO is disabled, leading to a build error: warning: (MAC80211 && MACSEC) selects CRYPTO_GCM which has unmet direct dependencies (CRYPTO) warning: (BT && CEPH_LIB && INET && MAC802154 && MAC80211 && BLK_DEV_RBD && MACSEC && AIRO_CS && LIBIPW && HOSTAP && USB_WUSB && RTLLIB_CRYPTO_CCMP && FS_ENCRYPTION && EXT4_ENCRYPTION && CEPH_FS && BIG_KEYS && ENCRYPTED_KEYS) selects CRYPTO_AES which has unmet direct dependencies (CRYPTO) crypto/built-in.o: In function `gcm_enc_copy_hash': aes_generic.c:(.text+0x2b8): undefined reference to `crypto_xor' aes_generic.c:(.text+0x2dc): undefined reference to `scatterwalk_map_and_copy' This adds an explicit 'select CRYPTO' statement the way that other drivers handle it.
