| * crypto: sha512 - remove imaginary and mystifying clearing of variablesLukas Bulwahn2021-08-271-3/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The function sha512_transform() assigns all local variables to 0 before returning to its caller with the intent to erase sensitive data. However, make clang-analyzer warns that all these assignments are dead stores, and as commit 7a4295f6c9d5 ("crypto: lib/sha256 - Don't clear temporary variables") already points out for sha256_transform(): The assignments to clear a through h and t1/t2 are optimized out by the compiler because they are unused after the assignments. Clearing individual scalar variables is unlikely to be useful, as they may have been assigned to registers, and even if stack spilling was required, there may be compiler-generated temporaries that are impossible to clear in any case. This applies here again as well. Drop meaningless clearing of local variables and avoid this way that the code suggests that data is erased, which simply does not happen.

| * crypto: x86/sm4 - add AES-NI/AVX2/x86_64 implementationTianjia Zhang2021-08-271-0/+22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Like the implementation of AESNI/AVX, this patch adds an accelerated implementation of AESNI/AVX2. In terms of code implementation, by reusing AESNI/AVX mode-related codes, the amount of code is greatly reduced. From the benchmark data, it can be seen that when the block size is 1024, compared to AVX acceleration, the performance achieved by AVX2 has increased by about 70%, it is also 7.7 times of the pure software implementation of sm4-generic. The main algorithm implementation comes from SM4 AES-NI work by libgcrypt and Markku-Juhani O. Saarinen at: https://github.com/mjosaarinen/sm4ni This optimization supports the four modes of SM4, ECB, CBC, CFB, and CTR. Since CBC and CFB do not support multiple block parallel encryption, the optimization effect is not obvious. Benchmark on Intel i5-6200U 2.30GHz, performance data of three implementation methods, pure software sm4-generic, aesni/avx acceleration, and aesni/avx2 acceleration, the data comes from the 218 mode and 518 mode of tcrypt. The abscissas are blocks of different lengths.

| * crypto: shash - avoid comparing pointers to exported functions under CFIArd Biesheuvel2021-06-171-3/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | crypto_shash_alg_has_setkey() is implemented by testing whether the .setkey() member of a struct shash_alg points to the default version, called shash_no_setkey(). As crypto_shash_alg_has_setkey() is a static inline, this requires shash_no_setkey() to be exported to modules. Unfortunately, when building with CFI, function pointers are routed via CFI stubs which are private to each module (or to the kernel proper) and so this function pointer comparison may fail spuriously. Let's fix this by turning crypto_shash_alg_has_setkey() into an out of line function.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Now we support sharing one page if PAGE_SIZE is not equal stripe size. To support this, it needs to support calculating xor value with different offsets for each r5dev. One offset array is used to record those offsets. In RMW mode, parity page is used as a source page. It sets ASYNC_TX_XOR_DROP_DST before calculating xor value in ops_run_prexor5. So it needs to add src_list and src_offs at the same time. Now it only needs src_list. So the xor value which is calculated is wrong. It can cause data corruption problem. I can reproduce this problem 100% on a POWER8 machine. The steps are: mdadm -CR /dev/md0 -l5 -n3 /dev/sdb1 /dev/sdc1 /dev/sdd1 --size=3G mkfs.xfs /dev/md0 mount /dev/md0 /mnt/test mount: /mnt/test: mount(2) system call failed: Structure needs cleaning.
