2020-01-22crypto: ccree - split overloaded usage of irq fieldGilad Ben-Yossef2-11/+9
We were using the irq field of the drvdata struct in an overloaded fahsion - saving the IRQ number during init and then storing the pending itnerrupt sources during interrupt in the same field. This worked because these usage are mutually exclusive but are confusing. So simplify the code and change the init use case to use a simple local variable.

2020-01-16crypto: vmx - reject xts inputs that are too shortDaniel Axtens1-0/+3
When the kernel XTS implementation was extended to deal with ciphertext stealing in commit 8083b1bf8163 ("crypto: xts - add support for ciphertext stealing"), a check was added to reject inputs that were too short. However, in the vmx enablement - commit 239668419349 ("crypto: vmx/xts - use fallback for ciphertext stealing"), that check wasn't added to the vmx implementation. This disparity leads to errors like the following: alg: skcipher: p8_aes_xts encryption unexpectedly succeeded on test vector "random: len=0 klen=64"; expected_error=-22, cfg="random: inplace may_sleep use_finup src_divs=[<flush>66.99%@+10, 33.1%@alignmask+1155]" Return -EINVAL if asked to operate with a cryptlen smaller than the AES block size. This brings vmx in line with the generic implementation.

2020-01-16crypto: curve25519 - Fix selftest build errorHerbert Xu3-10/+30
If CRYPTO_CURVE25519 is y, CRYPTO_LIB_CURVE25519_GENERIC will be y, but CRYPTO_LIB_CURVE25519 may be set to m, this causes build errors: lib/crypto/curve25519-selftest.o: In function `curve25519': curve25519-selftest.c:(.text.unlikely+0xc): undefined reference to `curve25519_arch' lib/crypto/curve25519-selftest.o: In function `curve25519_selftest': curve25519-selftest.c:(.init.text+0x17e): undefined reference to `curve25519_base_arch' This is because the curve25519 self-test code is being controlled by the GENERIC option rather than the overall CURVE25519 option, as is the case with blake2s. To recap, the GENERIC and ARCH options for CURVE25519 are internal only and selected by users such as the Crypto API, or the externally visible CURVE25519 option which in turn is selected by wireguard. The self-test is specific to the the external CURVE25519 option and should not be enabled by the Crypto API. This patch fixes this by splitting the GENERIC module from the CURVE25519 module with the latter now containing just the self-test.

Importantly, none of our changes affect the arithmetic or core code, but just involve the differing environment of kernel space. Signed-off-by: Jason A.
