Add Andy Polyakov's optimized assembly and NEON implementations for SHA-256/224. The sha256-armv4.pl script for generating the assembly code is from OpenSSL commit 51f8d095562f36cdaa6893597b5c609e943b0565. Compared to sha256-generic these implementations have the following tcrypt speed improvements on Motorola Nexus 6 (Snapdragon 805): bs b/u sha256-neon sha256-asm 16 16 x1.32 x1.19 64 16 x1.27 x1.15 64 64 x1.36 x1.20 256 16 x1.22 x1.11 256 64 x1.36 x1.19 256 256 x1.59 x1.23 1024 16 x1.21 x1.10 1024 256 x1.65 x1.23 1024 1024 x1.76 x1.25 2048 16 x1.21 x1.10 2048 256 x1.66 x1.23 2048 1024 x1.78 x1.25 2048 2048 x1.79 x1.25 4096 16 x1.20 x1.09 4096 256 x1.66 x1.23 4096 1024 x1.79 x1.26 4096 4096 x1.82 x1.26 8192 16 x1.20 x1.09 8192 256 x1.67 x1.23 8192 1024 x1.80 x1.26 8192 4096 x1.85 x1.28 8192 8192 x1.85 x1.27 Where bs refers to block size and b/u to bytes per update.

There are multiple problems in crypto_unregister_instance: 1) The cra_refcnt BUG_ON check is racy and can cause crashes. 2) The cra_refcnt check shouldn't exist at all. 3) There is no reference on tmpl to protect the tmpl->free call. This patch rewrites the function using crypto_remove_spawn which now morphs into crypto_remove_instance. Signed-off-by:

kmap_atomic() gives only the page address of the input page. Driver should take care of adding the offset of the scatterlist within the page to the returned page address. omap-sham driver is not adding the offset to page and directly operates on the return vale of kmap_atomic(), because of which the following error comes when running crypto tests: 00000000: d9 a1 1b 7c aa 90 3b aa 11 ab cb 25 00 b8 ac bf [ 2.338169] 00000010: c1 39 cd ff 48 d0 a8 e2 2b fa 33 a1 [ 2.344008] alg: hash: Chunking test 1 failed for omap-sha256 So adding the scatterlist offset to vaddr.

For cases where total length of an input SGs is not same as length of the input data for encryption, omap-aes driver crashes. This happens in the case when IPsec is trying to use omap-aes driver. To avoid this, we copy all the pages from the input SG list into a contiguous buffer and prepare a single element SG list for this buffer with length as the total bytes to crypt, which is similar thing that is done in case of unaligned lengths. Fixes: 6242332f ("crypto: omap-aes - Add support for cases of unaligned lengths") Signed-off-by:

omap_sham_handle_queue() can be called as part of done_task tasklet. During this its atomic and any calls to pm functions cannot sleep. But there is a call to pm_runtime_get_sync() (which can sleep) in omap_sham_handle_queue(), because of which the following appears: " [ 116.169969] BUG: scheduling while atomic: kworker/0:2/2676/0x00000100" Add pm_runtime_irq_safe() to avoid this.

Several hardware related cipher implementations are implemented as follows: a "helper" cipher implementation is registered with the kernel crypto API. Such helper ciphers are never intended to be called by normal users. In some cases, calling them via the normal crypto API may even cause failures including kernel crashes. In a normal case, the "wrapping" ciphers that use the helpers ensure that these helpers are invoked such that they cannot cause any calamity. Considering the AF_ALG user space interface, unprivileged users can call all ciphers registered with the crypto API, including these helper ciphers that are not intended to be called directly. That means, with AF_ALG user space may invoke these helper ciphers and may cause undefined states or side effects. To avoid any potential side effects with such helpers, the patch prevents the helpers to be called directly. A new cipher type flag is added: CRYPTO_ALG_INTERNAL. This flag shall be used to mark helper ciphers. These ciphers can only be used if the caller invoke the cipher with CRYPTO_ALG_INTERNAL in the type and mask field. Signed-off-by:
