Pull crypto fixes from Herbert Xu: "This push fixes a memory corruption issue in caam, as well as reverting the new optimised crct10dif implementation as it breaks boot on initrd systems. Hopefully crct10dif will be reinstated once the supporting code is added so that it doesn't break boot" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: Revert "crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework" crypto: caam - Fixed the memory out of bound overwrite issue

This reverts commits 67822649d7305caf3dd50ed46c27b99c94eff996 39761214eefc6b070f29402aa1165f24d789b3f7 0b95a7f85718adcbba36407ef88bba0a7379ed03 31d939625a9a20b1badd2d4e6bf6fd39fa523405 2d31e518a42828df7877bca23a958627d60408bc Unfortunately this change broke boot on some systems that used an initrd which does not include the newly created crct10dif modules. As these modules are required by sd_mod under certain configurations this is a serious problem. Signed-off-by: Herbert Xu

lib: add lz4 compressor module

2013-07-09T17:33:30Z

This patchset is for supporting LZ4 compression and the crypto API using it. As shown below, the size of data is a little bit bigger but compressing speed is faster under the enabled unaligned memory access. We can use lz4 de/compression through crypto API as well. Also, It will be useful for another potential user of lz4 compression. lz4 Compression Benchmark: Compiler: ARM gcc 4.6.4 ARMv7, 1 GHz based board Kernel: linux 3.4 Uncompressed data Size: 101 MB Compressed Size compression Speed LZO 72.1MB 32.1MB/s, 33.0MB/s(UA) LZ4 75.1MB 30.4MB/s, 35.9MB/s(UA) LZ4HC 59.8MB 2.4MB/s, 2.5MB/s(UA) - UA: Unaligned memory Access support - Latest patch set for LZO applied This patch: Add support for LZ4 compression in the Linux Kernel. LZ4 Compression APIs for kernel are based on LZ4 implementation by Yann Collet and were changed for kernel coding style. LZ4 homepage : http://fastcompression.blogspot.com/p/lz4.html LZ4 source repository : http://code.google.com/p/lz4/ svn revision : r90 Two APIs are added: lz4_compress() support basic lz4 compression whereas lz4hc_compress() support high compression or CPU performance get lower but compression ratio get higher. Also, we require the pre-allocated working memory with the defined size and destination buffer must be allocated with the size of lz4_compressbound.

lib: Move fonts from drivers/video/console/ to lib/fonts/

2013-06-28T08:28:22Z

Several drivers need font support independent of CONFIG_VT, cfr. commit 9cbce8d7e1dae0744ca4f68d62aa7de18196b6f4, "console/font: Refactor font support code selection logic"). Hence move the fonts and their support logic from drivers/video/console/ to its own library directory lib/fonts/. This also allows to limit processing of drivers/video/console/Makefile to CONFIG_VT=y again. [Kevin Hilman : Update arch/arm/boot/compressed/Makefile] Signed-off-by: Geert Uytterhoeven

net: core: move mac_pton() to lib/net_utils.c

2013-06-05T19:00:27Z

Since we have at least one user of this function outside of CONFIG_NET scope, we have to provide this function independently. The proposed solution is to move it under lib/net_utils.c with corresponding configuration variable and select wherever it is needed.

crypto: crct10dif - Wrap crc_t10dif function all to use crypto transform framework

2013-05-20T12:11:01Z

When CRC T10 DIF is calculated using the crypto transform framework, we wrap the crc_t10dif function call to utilize it. This allows us to take advantage of any accelerated CRC T10 DIF transform that is plugged into the crypto framework. Signed-off-by: Tim Chen Signed-off-by: Herbert Xu

Move utf16 functions to kernel core and rename

2013-04-15T20:23:03Z

We want to be able to use the utf16 functions that are currently present in the EFI variables code in platform-specific code as well. Move them to the kernel core, and in the process rename them to accurately describe what they do - they don't handle UTF16, only UCS2. Signed-off-by: Matthew Garrett Signed-off-by: Matt Fleming
