Subject: [PATCH v4 1/1] crypto: vmx - add missing dependencies
Date: Wed, 23 Feb 2022 16:11:15 +0100	[thread overview]
Message-ID: <20220223151115.28536-1-pvorel@suse.cz> (raw)

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

[    0.550892] 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")
