Hasn't this been a problem since commit 537c1445ab0b, which added an AEAD algorithm to this module? > diff --git a/arch/arm64/crypto/Kconfig b/arch/arm64/crypto/Kconfig > index 4391a463abd7..6b2ecc193bc0 100644 > --- a/arch/arm64/crypto/Kconfig > +++ b/arch/arm64/crypto/Kconfig > @@ -71,6 +71,7 @@ config CRYPTO_GHASH_ARM64_CE > select CRYPTO_HASH > select CRYPTO_GF128MUL > select CRYPTO_LIB_AES > + select CRYPTO_AEAD2 I don't think CRYPTO_AEAD2 is meant to be selected directly. It should be CRYPTO_AEAD instead. - Eric

Ah, you are probably right. crypto_unregister_aead and crypto_register_aead are already there in the previous commit. > > > diff --git a/arch/arm64/crypto/Kconfig b/arch/arm64/crypto/Kconfig > > index 4391a463abd7..6b2ecc193bc0 100644 > > --- a/arch/arm64/crypto/Kconfig > > +++ b/arch/arm64/crypto/Kconfig > > @@ -71,6 +71,7 @@ config CRYPTO_GHASH_ARM64_CE > > select CRYPTO_HASH > > select CRYPTO_GF128MUL > > select CRYPTO_LIB_AES > > + select CRYPTO_AEAD2 > > I don't think CRYPTO_AEAD2 is meant to be selected directly.
