* crypto: aegis - fix badly optimized clang outputArnd Bergmann2019-07-271-7/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Clang sometimes makes very different inlining decisions from gcc. In case of the aegis crypto algorithms, it decides to turn the innermost primitives (and, xor, ...) into separate functions but inline most of the rest. This results in a huge amount of variables spilled on the stack, leading to rather slow execution as well as kernel stack usage beyond the 32-bit warning limit when CONFIG_KASAN is enabled: crypto/aegis256.c:123:13: warning: stack frame size of 648 bytes in function 'crypto_aegis256_encrypt_chunk' [-Wframe-larger-than=] crypto/aegis256.c:366:13: warning: stack frame size of 1264 bytes in function 'crypto_aegis256_crypt' [-Wframe-larger-than=] crypto/aegis256.c:187:13: warning: stack frame size of 656 bytes in function 'crypto_aegis256_decrypt_chunk' [-Wframe-larger-than=] crypto/aegis128l.c:135:13: warning: stack frame size of 832 bytes in function 'crypto_aegis128l_encrypt_chunk' [-Wframe-larger-than=] crypto/aegis128l.c:415:13: warning: stack frame size of 1480 bytes in function 'crypto_aegis128l_crypt' [-Wframe-larger-than=] crypto/aegis128l.c:218:13: warning: stack frame size of 848 bytes in function 'crypto_aegis128l_decrypt_chunk' [-Wframe-larger-than=] crypto/aegis128.c:116:13: warning: stack frame size of 584 bytes in function 'crypto_aegis128_encrypt_chunk' [-Wframe-larger-than=] crypto/aegis128.c:351:13: warning: stack frame size of 1064 bytes in function 'crypto_aegis128_crypt' [-Wframe-larger-than=] crypto/aegis128.c:177:13: warning: stack frame size of 592 bytes in function 'crypto_aegis128_decrypt_chunk' [-Wframe-larger-than=] Forcing the primitives to all get inlined avoids the issue and the resulting code is similar to what gcc produces.

* crypto: aegis - avoid prerotated AES tablesArd Biesheuvel2019-07-261-8/+6
| | | | | | | | | | | | | | | | | | | The generic AES code provides four sets of lookup tables, where each set consists of four tables containing the same 32-bit values, but rotated by 0, 8, 16 and 24 bits, respectively. This makes sense for CISC architectures such as x86 which support memory operands, but for other architectures, the rotates are quite cheap, and using all four tables needlessly thrashes the D-cache, and actually hurts rather than helps performance. Since x86 already has its own implementation of AEGIS based on AES-NI instructions, let's tweak the generic implementation towards other architectures, and avoid the prerotated tables, and perform the rotations inline. On ARM Cortex-A53, this results in a ~8% speedup.

* crypto: aegis - Cleanup license messThomas Gleixner2019-01-251-6/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Precise and non-ambiguous license information is important. The recently added aegis header file has a SPDX license identifier, which is nice, but at the same time it has a contradictionary license boiler plate text. SPDX-License-Identifier: GPL-2.0 versus * This program is free software; you can redistribute it and/or modify it * under the terms of the GNU General Public License as published by the Free * Software Foundation; either version 2 of the License, or (at your option) * any later version Oh well. As the other aegis related files are licensed under the GPL v2 or later, it's assumed that the boiler plate code is correct, but the SPDX license identifier is wrong. Fix the SPDX identifier and remove the boiler plate as it is redundant.

* crypto: aegis - Add generic AEGIS AEAD implementationsOndrej Mosnacek2018-05-191-0/+80
This patch adds the generic implementation of the AEGIS family of AEAD algorithms (AEGIS-128, AEGIS-128L, and AEGIS-256). The original authors of AEGIS are Hongjun Wu and Bart Preneel. At the time of writing, AEGIS is one of the finalists in CAESAR, an open competition intended to select a portfolio of alternatives to the problematic AES-GCM: https://competitions.cr.yp.to/caesar-submissions.html https://competitions.cr.yp.to/round3/aegisv11.pdf Signed-off-by: Ondrej Mosnacek <omosnacek@gmail.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>
