Subject: [PATCH] linux-next 20190731 - aegis128-core.c fails to build
Date: Thu, 01 Aug 2019 00:51:54 -0400 [thread overview]
Message-ID: <13353.1564635114@turing-police> (raw)
The recent NEON SIMD patches break the build if CONFIG_CRYPTO_AEGIS128_SIMD isn't set:
MODPOST 558 modules
ERROR: "crypto_aegis128_decrypt_chunk_simd" [crypto/aegis128.ko] undefined!
ERROR: "crypto_aegis128_update_simd" [crypto/aegis128.ko] undefined!
ERROR: "crypto_aegis128_encrypt_chunk_simd" [crypto/aegis128.ko] undefined!
make[1]: *** [scripts/Makefile.modpost:105: modules-modpost] Error 1
make: *** [Makefile:1299: modules] Error 2
Add proper definitions and stubs to aegis.h so it builds both ways. This
necessitated moving other stuff from aegis128-core.c to aegis.h so things were
defined in the proper order.
