From mboxrd@z Thu Jan 1 00:00:00 1970 From: Arnd Bergmann Subject: [PATCH] mac802154: select CRYPTO when needed Date: Tue, 19 May 2015 14:18:35 +0200 Message-ID: <4189396.LhxDXkIPfr@wuerfel> Mime-Version: 1.0 Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: 7Bit Cc: "David S. Miller" , linux-wpan@vger.kernel.org, netdev@vger.kernel.org, linux-kernel@vger.kernel.org, linux-arm-kernel@lists.infradead.org To: Alexander Aring Return-path: Sender: linux-kernel-owner@vger.kernel.org List-Id: netdev.vger.kernel.org The mac802154 subsystem uses functions from the crypto layer and correctly selects the individual crypto algorithms, but fails to build when the crypto layer is disabled altogether: crypto/built-in.o: In function `crypto_ctr_free': :(.text+0x80): undefined reference to `crypto_drop_spawn' crypto/built-in.o: In function `crypto_rfc3686_free': :(.text+0xac): undefined reference to `crypto_drop_spawn' crypto/built-in.o: In function `crypto_ctr_crypt': :(.text+0x2f0): undefined reference to `blkcipher_walk_virt_block' :(.text+0x2f8): undefined reference to `crypto_inc' To solve that, this patch also selects the core crypto code, like all other users of that code do.
