Hi Herbert,
I got the attached error report. This is due to CRYPTO_HASH2 is selected as m
whereas security/keys/dh.c is compiled as y. Note CRYPTO_HASH is selected as
y.
dh.c requires shash.
Kconfig for dh.c contains:
config KEY_DH_OPERATIONS
bool "Diffie-Hellman operations on retained keys"
depends on KEYS
select MPILIB
select CRYPTO_HASH
Shall I select CRYPTO_HASH2 instead or in addition to CRYPTO_HASH?
Thanks.
Ciao
Stephan
