crypto: aesni - fix failing setkey for rfc4106-gcm-aesni

2015-06-29T08:06:30+00:00

rfc4106(gcm(aes)) uses ctr(aes) to generate hash key. ctr(aes) needs chainiv, but the chainiv gets initialized after aesni_intel when both are statically linked so the setkey fails. This patch forces aesni_intel to be initialized after chainiv. Signed-off-by: Tadeusz Struk Tested-by: Linus Torvalds Signed-off-by: Herbert Xu

Pull crypto update from Herbert Xu: "Here is the crypto update for 4.2: API: - Convert RNG interface to new style. - New AEAD interface with one SG list for AD and plain/cipher text. All external AEAD users have been converted. - New asymmetric key interface (akcipher). Algorithms: - Chacha20, Poly1305 and RFC7539 support. - New RSA implementation. - Jitter RNG. - DRBG is now seeded with both /dev/random and Jitter RNG. If kernel pool isn't ready then DRBG will be reseeded when it is. - DRBG is now the default crypto API RNG, replacing krng. - 842 compression (previously part of powerpc nx driver). Drivers: - Accelerated SHA-512 for arm64. - New Marvell CESA driver that supports DMA and more algorithms. - Updated powerpc nx 842 support. - Added support for SEC1 hardware to talitos" * git://git.kernel.org/pub/scm/linux/kernel/git/herbert/crypto-2.6: (292 commits) crypto: marvell/cesa - remove COMPILE_TEST dependency crypto: algif_aead - Temporarily disable all AEAD algorithms crypto: af_alg - Forbid the use internal algorithms crypto: echainiv - Only hold RNG during initialisation crypto: seqiv - Add compatibility support without RNG crypto: eseqiv - Offer normal cipher functionality without RNG crypto: chainiv - Offer normal cipher functionality without RNG crypto: user - Add CRYPTO_MSG_DELRNG crypto: user - Move cryptouser.h to uapi crypto: rng - Do not free default RNG when it becomes unused crypto: skcipher - Allow givencrypt to be NULL crypto: sahara - propagate the error on clk_disable_unprepare() failure crypto: rsa - fix invalid select for AKCIPHER crypto: picoxcell - Update to the current clk API crypto: nx - Check for bogus firmware properties crypto: marvell/cesa - add DT bindings documentation crypto: marvell/cesa - add support for Kirkwood and Dove SoCs crypto: marvell/cesa - add support for Orion SoCs crypto: marvell/cesa - add allhwsupport module parameter crypto: marvell/cesa - add support for all armada SoCs ...

crypto: aesni - fix crypto_fpu_exit() section mismatch

2015-06-15T10:15:58+00:00

The '__init aesni_init()' function calls the '__exit crypto_fpu_exit()' function directly. Since they are in different sections, this generates a warning. make CONFIG_DEBUG_SECTION_MISMATCH=y ... WARNING: arch/x86/crypto/aesni-intel.o(.init.text+0x12b): Section mismatch in reference from the function init_module() to the function .exit.text:crypto_fpu_exit() The function __init init_module() references a function __exit crypto_fpu_exit(). This is often seen when error handling in the init function uses functionality in the exit path. The fix is often to remove the __exit annotation of crypto_fpu_exit() so it may be used outside an exit section. Fix the warning by removing the __exit annotation.

crypto: aesni - Convert rfc4106 to new AEAD interface

This patch converts the low-level __gcm-aes-aesni algorithm to the new AEAD interface. Signed-off-by: Herbert Xu

crypto: aesni - Convert top-level rfc4106 algorithm to new interface

2015-06-03T02:48:36+00:00

This patch converts rfc4106-gcm-aesni to the new AEAD interface. The low-level interface remains as is for now because we can't touch it until cryptd itself is upgraded. In the conversion I've also removed the duplicate copy of the context in the top-level algorithm. Now all processing is carried out in the low-level __driver-gcm-aes-aesni algorithm.

x86/fpu, crypto: Fix AVX2 feature tests

2015-05-22T08:58:45+00:00

For some CPU models I broke the AVX2 feature detection in: 7bc371faa9cd ("x86/fpu, crypto x86/camellia_aesni_avx2: Simplify the camellia_aesni_init() xfeature checks") 534ff06e3929 ("x86/fpu, crypto x86/serpent_avx2: Simplify the init() xfeature checks") ... because I did not realize that it's possible for a CPU to support the xstate necessary for AVX2 execution (XSTATE_YMM), but not have the AVX2 instructions themselves. Restore the necessary CPUID checks as well. Cc: Andy Lutomirski Cc: Borislav Petkov Cc: Dave Hansen Cc: Fenghua Yu Cc: H.

x86/fpu, crypto x86/sha1_mb: Remove FPU internal headers from sha1_mb.c

This file only uses the public FPU APIs, so remove the xcr.h, fpu/xstate.h and fpu/internal.h headers and add the fpu/api.h include.

x86/fpu, crypto x86/serpent_avx2: Simplify the init() xfeature checks

2015-05-19T13:47:59+00:00

Use the new 'cpu_has_xfeatures()' function to query AVX CPU support. This has the following advantages to the driver: - Decouples the driver from FPU internals: it's now only using . - Removes detection complexity from the driver, no more raw XGETBV instruction - Shrinks the code a bit. - Standardizes feature name error message printouts across drivers There are also advantages to the x86 FPU code: once all drivers are decoupled from internals we can move them out of common headers and we'll also be able to remove xcr.h.
