2019-08-22crypto: sha256 - Move lib/sha256.c to lib/cryptoHans de Goede1-28/+0
Generic crypto implementations belong under lib/crypto not directly in lib, likewise the header should be in include/crypto, not include/linux. Note that the code in lib/crypto/sha256.c is not yet available for generic use after this commit, it is still only used by the s390 and x86 purgatory code. Making it suitable for generic use is done in further patches in this series. Signed-off-by: Hans de Goede <hdegoede@redhat.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

2018-04-13kernel/kexec_file.c: move purgatories sha256 to common codePhilipp Rudo1-0/+30
The code to verify the new kernels sha digest is applicable for all architectures. Move it to common code. One problem is the string.c implementation on x86. Currently sha256 includes x86/boot/string.h which defines memcpy and memset to be gcc builtins. By moving the sha256 implementation to common code and changing the include to linux/string.h both functions are no longer defined. Thus definitions have to be provided in x86/purgatory/string.c Link: http://lkml.kernel.org/r/20180321112751.22196-12-prudo@linux.vnet.ibm.com Signed-off-by: Philipp Rudo <prudo@linux.vnet.ibm.com> Acked-by: Dave Young <dyoung@redhat.com> Cc: AKASHI Takahiro <takahiro.akashi@linaro.org> Cc: Eric Biederman <ebiederm@xmission.com> Cc: Heiko Carstens <heiko.carstens@de.ibm.com> Cc: Ingo Molnar <mingo@kernel.org> Cc: Martin Schwidefsky <schwidefsky@de.ibm.com> Cc: Michael Ellerman <mpe@ellerman.id.au> Cc: Thiago Jung Bauermann <bauerman@linux.vnet.ibm.com> Cc: Vivek Goyal <vgoyal@redhat.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org>
