[PATCH v3 2/2] crypto: vmx - add missing dependencies
vmx-crypto module depends on CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or CRYPTO_XTS, thus add them. These dependencies are likely to be enabled, but if CRYPTO_DEV_VMX=y && !CRYPTO_MANAGER_DISABLE_TESTS and either of CRYPTO_AES, CRYPTO_CBC, CRYPTO_CTR or CRYPTO_XTS is built as module or disabled, alg_test() from crypto/testmgr.c complains during boot about failing to allocate the generic fallback implementations (2 == ENOENT): [0.540953] Failed to allocate xts(aes) fallback: -2 [0.541014] alg: skcipher: failed to allocate transform for p8_aes_xts: -2 [0.541120] alg: self-tests for p8_aes_xts (xts(aes)) failed (rc=-2) [0.50] Failed to allocate ctr(aes) fallback: -2 [0.544497] alg: skcipher: failed to allocate transform for p8_aes_ctr: -2 [0.544603] alg: self-tests for p8_aes_ctr (ctr(aes)) failed (rc=-2) [0.547992] Failed to allocate cbc(aes) fallback: -2 [0.548052] alg: skcipher: failed to allocate transform for p8_aes_cbc: -2 [0.548156] alg: self-tests for p8_aes_cbc (cbc(aes)) failed (rc=-2) [0.550745] Failed to allocate transformation for 'aes': -2 [0.550801] alg: cipher: Failed to load transform for p8_aes: -2 [0.550892] alg: self-tests for p8_aes (aes) failed (rc=-2) Fixes: c07f5d3da643 ("crypto: vmx - Adding support for XTS") Fixes: d2e3ae6f3aba ("crypto: vmx - Enabling VMX module for PPC64") Suggested-by: Nicolai Stange Signed-off-by: Petr Vorel --- changes v2->v3: * more less the same, just in drivers/crypto/Kconfig (previously it was in drivers/crypto/vmx/Kconfig) * change commit subject to be compatible drivers/crypto/Kconfig | 4 1 file changed, 4 insertions(+) diff --git a/drivers/crypto/Kconfig b/drivers/crypto/Kconfig index 923fa1effb4a..0eafb2a49f04 100644 --- a/drivers/crypto/Kconfig +++ b/drivers/crypto/Kconfig @@ -764,7 +764,11 @@ config CRYPTO_DEV_QCOM_RNG config CRYPTO_DEV_VMX tristate "Power VMX cryptographic acceleration instructions driver" depends on PPC64 && VSX + select CRYPTO_AES + select CRYPTO_CBC + select CRYPTO_CTR select CRYPTO_GHASH + select CRYPTO_XTS help Support for VMX cryptographic acceleration instructions on Power8 CPU.
