2016-12-14crypto: skcipher - fix crash in virtual walkArd Biesheuvel
The new skcipher walk API may crash in the following way. (Interestingly, the tcrypt boot time tests seem unaffected, while an explicit test using the module triggers it) Unable to handle kernel NULL pointer dereference at virtual address 00000000 ...

Since skcipher_walk_done() already deals with the case where walk->buffer == walk->page, it appears to be the intention that walk->buffer point to walk->page after skcipher_next_slow(), so ensure that is the case.

2016-12-14sign-file: Fix inplace signing when src and dst names are both specifiedAlex Yashchenko
When src and dst both are specified and they point to the same file the sign-file utility will write only signature to the dst file and the module (.ko file) body will not be written. That happens because we open the same file with "rb" and "wb" flags, from fopen man: w Truncate file to zero length or create text file for writing. The stream is positioned at the beginning of the file. ... bm = BIO_new_file(module_name, "rb"); ... bd = BIO_new_file(dest_name, "wb"); ... while ((n = BIO_read(bm, buf, sizeof(buf))), n > 0) { ERR(BIO_write(bd, buf, n) < 0, "%s", dest_name); } ...

2016-12-08crypto: testmgr - fix overlap in chunked tests againArd Biesheuvel
Commit 7e4c7f17cde2 ("crypto: testmgr - avoid overlap in chunked tests") attempted to address a problem in the crypto testmgr code where chunked test cases are copied to memory in a way that results in overlap. However, the fix recreated the exact same issue for other chunked tests, by putting IDX3 within 492 bytes of IDX1, which causes overlap if the first chunk exceeds 492 bytes, which is the case for at least one of the xts(aes) test cases. So increase IDX3 by another 1000 bytes. Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

This is a combination of the the Intel algorithm implemented using SSE and PCLMULQDQ instructions from arch/x86/crypto/crc32-pclmul_asm.S, and the new CRC32 extensions introduced for both 32-bit and 64-bit ARM in version 8 of the architecture. Two versions of the above combo are provided, one for CRC32 and one for CRC32C. The PMULL/NEON algorithm is faster, but operates on blocks of at least 64 bytes, and on multiples of 16 bytes only. For the remaining input, or for all input on systems that lack the PMULL 64x64->128 instructions, the CRC32 instructions will be used.

2016-11-30crypto: drbg - prevent invalid SG mappingsStephan Mueller
When using SGs, only heap memory (memory that is valid as per virt_addr_valid) is allowed to be referenced. The CTR DRBG used to reference the caller-provided memory directly in an SG. In case the caller provided stack memory pointers, the SG mapping is not considered to be valid. In some cases, this would even cause a paging fault. The change adds a new scratch buffer that is used unconditionally to catch the cases where the caller-provided buffer is not suitable for use in an SG. The crypto operation of the CTR DRBG produces its output with that scratch buffer and finally copies the content of the scratch buffer to the caller's buffer. The scratch buffer is allocated during allocation time of the CTR DRBG as its access is protected with the DRBG mutex.
