From 597179b0ba550bd83fab1a9d57c42a9343c58514 Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 18 Jun 2019 13:22:13 +0200 Subject: [PATCH] ipsec: select crypto ciphers for xfrm_algo kernelci.org reports failed builds on arc because of what looks like an old missed 'select' statement: net/xfrm/xfrm_algo.o: In function `xfrm_probe_algs': xfrm_algo.c:(.text+0x1e8): undefined reference to `crypto_has_ahash' I don't see this in randconfig builds on other architectures, but it's fairly clear we want to select the hash code for it, like we do for all its other users. As Herbert points out, CRYPTO_BLKCIPHER is also required even though it has not popped up in build tests.
