From 796f458ad791979fc3a6e4d425c5cecad575ff0c Mon Sep 17 00:00:00 2001 From: Arnd Bergmann Date: Tue, 18 Jun 2019 14:13:47 +0200 Subject: [PATCH] crypto: asymmetric_keys - select CRYPTO_HASH where needed [ Upstream commit 90acc0653d2bee203174e66d519fbaaa513502de ] Build testing with some core crypto options disabled revealed a few modules that are missing CRYPTO_HASH: crypto/asymmetric_keys/x509_public_key.o: In function `x509_get_sig_params': x509_public_key.c:(.text+0x4c7): undefined reference to `crypto_alloc_shash' x509_public_key.c:(.text+0x5e5): undefined reference to `crypto_shash_digest' crypto/asymmetric_keys/pkcs7_verify.o: In function `pkcs7_digest.isra.0': pkcs7_verify.c:(.text+0xab): undefined reference to `crypto_alloc_shash' pkcs7_verify.c:(.text+0x1b2): undefined reference to `crypto_shash_digest' pkcs7_verify.c:(.text+0x3c1): undefined reference to `crypto_shash_update' pkcs7_verify.c:(.text+0x411): undefined reference to `crypto_shash_finup' This normally doesn't show up in randconfig tests because there is a large number of other options that select CRYPTO_HASH.
