From: Arnd Bergmann Date: Tue, 18 Jun 2019 11:22:13 +0000 (+0200) Subject: ipsec: select crypto ciphers for xfrm_algo X-Git-Tag: v5.1.20~245 X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a275d049f958b18840375309fcda8fe084b8e6b8;p=thirdparty%2Fkernel%2Fstable.git ipsec: select crypto ciphers for xfrm_algo [ Upstream commit 597179b0ba550bd83fab1a9d57c42a9343c58514 ] 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.
