License cleanup: add SPDX GPL-2.0 license identifier to files with no license Many source files in the tree are missing licensing information, which makes it harder for compliance tools to determine the correct license. By default all files without license information are under the default license of the kernel, which is GPL version 2. Update the files which contain no license information with the 'GPL-2.0' SPDX license identifier. The SPDX identifier is a legally binding shorthand, which can be used instead of the full boiler plate text. This patch is based on work done by Thomas Gleixner and Kate Stewart and Philippe Ombredanne. How this work was done: Patches were generated and checked against linux-4.14-rc6 for a subset of the use cases: - file had no licensing information it it. - file was a */uapi/* one with no licensing information in it, - file was a */uapi/* one with existing licensing information, Further patches will be generated in subsequent months to fix up cases where non-standard license headers were used, and references to license had to be inferred by heuristics based on keywords. The analysis to determine which SPDX License Identifier to be applied to a file was done in a spreadsheet of side by side results from of the output of two independent scanners (ScanCode & Windriver) producing SPDX tag:value files created by Philippe Ombredanne. Philippe prepared the base worksheet, and did an initial spot review of a few 1000 files. The 4.13 kernel was the starting point of the analysis with 60,537 files assessed. Kate Stewart did a file by file comparison of the scanner results in the spreadsheet to determine which SPDX license identifier(s) to be applied to the file. She confirmed any determination that was not immediately clear with lawyers working with the Linux Foundation. Criteria used to select files for SPDX license identifier tagging was: - Files considered eligible had to be source code files. - Make and config files were included as candidates if they contained >5 lines of source - File already had some variant of a license header in it (even if <5 lines). All documentation files were explicitly excluded. The following heuristics were used to determine which SPDX license identifiers to apply. - when both scanners couldn't find any license traces, file was considered to have no license information in it, and the top level COPYING file license applied. For non */uapi/* files that summary was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 11139 and resulted in the first patch in this series. If that file was a */uapi/* path one, it was "GPL-2.0 WITH Linux-syscall-note" otherwise it was "GPL-2.0". Results of that was: SPDX license identifier # files ---------------------------------------------------|------- GPL-2.0 WITH Linux-syscall-note 930 and resulted in the second patch in this series. - if a file had some form of licensing information in it, and was one of the */uapi/* ones, it was denoted with the Linux-syscall-note if any GPL family license was found in the file or had no licensing in it (per prior point). Results summary: SPDX license identifier # files ---------------------------------------------------|------ GPL-2.0 WITH Linux-syscall-note 270 GPL-2.0+ WITH Linux-syscall-note 169 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-2-Clause) 21 ((GPL-2.0 WITH Linux-syscall-note) OR BSD-3-Clause) 17 LGPL-2.1+ WITH Linux-syscall-note 15 GPL-1.0+ WITH Linux-syscall-note 14 ((GPL-2.0+ WITH Linux-syscall-note) OR BSD-3-Clause) 5 LGPL-2.0+ WITH Linux-syscall-note 4 LGPL-2.1 WITH Linux-syscall-note 3 ((GPL-2.0 WITH Linux-syscall-note) OR MIT) 3 ((GPL-2.0 WITH Linux-syscall-note) AND MIT) 1 and that resulted in the third patch in this series. - when the two scanners agreed on the detected license(s), that became the concluded license(s). - when there was disagreement between the two scanners (one detected a license but the other didn't, or they both detected different licenses) a manual inspection of the file occurred. - In most cases a manual inspection of the information in the file resulted in a clear resolution of the license that should apply (and which scanner probably needed to revisit its heuristics). - When it was not immediately clear, the license identifier was confirmed with lawyers working with the Linux Foundation. - If there was any question as to the appropriate license identifier, the file was flagged for further research and to be revisited later in time. In total, over 70 hours of logged manual review was done on the spreadsheet to determine the SPDX license identifiers to apply to the source files by Kate, Philippe, Thomas and, in some cases, confirmation by lawyers working with the Linux Foundation. Kate also obtained a third independent scan of the 4.13 code base from FOSSology, and compared selected files where the other two scanners disagreed against that SPDX file, to see if there was new insights. The Windriver scanner is based on an older version of FOSSology in part, so they are related. Thomas did random spot checks in about 500 files from the spreadsheets for the uapi headers and agreed with SPDX license identifier in the files he inspected. For the non-uapi files Thomas did random spot checks in about 15000 files. In initial set of patches against 4.14-rc6, 3 files were found to have copy/paste license identifier errors, and have been fixed to reflect the correct identifier. Additionally Philippe spent 10 hours this week doing a detailed manual inspection and review of the 12,461 patched files from the initial patch version early this week with: - a full scancode scan run, collecting the matched texts, detected license ids and scores - reviewing anything where there was a license detected (about 500+ files) to ensure that the applied SPDX license was correct - reviewing anything where there was no detection but the patch license was not GPL-2.0 WITH Linux-syscall-note to ensure that the applied SPDX license was correct This produced a worksheet with 20 files needing minor correction. This worksheet was then exported into 3 different .csv files for the different types of files to be modified. These .csv files were then reviewed by Greg. Thomas wrote a script to parse the csv files and add the proper SPDX tag to the file, in the format that the file expected. This script was further refined by Greg based on the output to detect more types of files automatically and to distinguish between header and source .c files (which need different comment types.) Finally Greg ran the script using the .csv files to generate the patches.

async_tx: add the async_tx api The async_tx api provides methods for describing a chain of asynchronous bulk memory transfers/transforms with support for inter-transactional dependencies. It is implemented as a dmaengine client that smooths over the details of different hardware offload engine implementations. Code that is written to the api can optimize for asynchronous operation and the api will fit the chain of operations to the available offload resources. I imagine that any piece of ADMA hardware would register with the 'async_*' subsystem, and a call to async_X would be routed as appropriate, or be run in-line. - Neil Brown async_tx exploits the capabilities of struct dma_async_tx_descriptor to provide an api of the following general format: struct dma_async_tx_descriptor * async_<operation>(..., struct dma_async_tx_descriptor *depend_tx, dma_async_tx_callback cb_fn, void *cb_param) { struct dma_chan *chan = async_tx_find_channel(depend_tx, <operation>); struct dma_device *device = chan ? chan->device : NULL; int int_en = cb_fn ? 1 : 0; struct dma_async_tx_descriptor *tx = device ? device->device_prep_dma_<operation>(chan, len, int_en) : NULL; if (tx) { /* run <operation> asynchronously */ ... tx->tx_set_dest(addr, tx, index); ... tx->tx_set_src(addr, tx, index); ... async_tx_submit(chan, tx, flags, depend_tx, cb_fn, cb_param); } else { /* run <operation> synchronously */ ... <operation> ... async_tx_sync_epilog(flags, depend_tx, cb_fn, cb_param); } return tx; } async_tx_find_channel() returns a capable channel from its pool. The channel pool is organized as a per-cpu array of channel pointers. The async_tx_rebalance() routine is tasked with managing these arrays. In the uniprocessor case async_tx_rebalance() tries to spread responsibility evenly over channels of similar capabilities. For example if there are two copy+xor channels, one will handle copy operations and the other will handle xor. In the SMP case async_tx_rebalance() attempts to spread the operations evenly over the cpus, e.g. cpu0 gets copy channel0 and xor channel0 while cpu1 gets copy channel 1 and xor channel 1. When a dependency is specified async_tx_find_channel defaults to keeping the operation on the same channel. A xor->copy->xor chain will stay on one channel if it supports both operation types, otherwise the transaction will transition between a copy and a xor resource. Currently the raid5 implementation in the MD raid456 driver has been converted to the async_tx api. A driver for the offload engines on the Intel Xscale series of I/O processors, iop-adma, is provided in a later commit. With the iop-adma driver and async_tx, raid456 is able to offload copy, xor, and xor-zero-sum operations to hardware engines. On iop342 tiobench showed higher throughput for sequential writes (20 - 30% improvement) and sequential reads to a degraded array (40 - 55% improvement). For the other cases performance was roughly equal, +/- a few percentage points. On a x86-smp platform the performance of the async_tx implementation (in synchronous mode) was also +/- a few percentage points of the original implementation. According to 'top' on iop342 CPU utilization drops from ~50% to ~15% during a 'resync' while the speed according to /proc/mdstat doubles from ~25 MB/s to ~50 MB/s. The tiobench command line used for testing was: tiobench --size 2048 --block 4096 --block 131072 --dir /mnt/raid --numruns 5 * iop342 had 1GB of memory available Details: * if CONFIG_DMA_ENGINE=n the asynchronous path is compiled away by making async_tx_find_channel a static inline routine that always returns NULL * when a callback is specified for a given transaction an interrupt will fire at operation completion time and the callback will occur in a tasklet. if the the channel does not support interrupts then a live polling wait will be performed * the api is written as a dmaengine client that requests all available channels * In support of dependencies the api implicitly schedules channel-switch interrupts. The interrupt triggers the cleanup tasklet which causes pending operations to be scheduled on the next channel * Xor engines treat an xor destination address differently than a software xor routine. To the software routine the destination address is an implied source, whereas engines treat it as a write-only destination. This patch modifies the xor_blocks routine to take a an explicit destination address to mirror the hardware.

crypto: api - Add fips_enable flag Add the ability to turn FIPS-compliant mode on or off at boot In order to be FIPS compliant, several check may need to be preformed that may be construed as unusefull in a non-compliant mode. This patch allows us to set a kernel flag incating that we are running in a fips-compliant mode from boot up. It also exports that mode information to user space via a sysctl (/proc/sys/crypto/fips_enabled). Tested successfully by me.

AEAD algorithms perform authentication and encryption in one step. Traditionally users (such as IPsec) would use two different crypto algorithms to perform these. With AEAD this comes down to one algorithm and one operation. Of course if traditional algorithms were used we'd still be doing two operations underneath.

[CRYPTO] cipher: Added block cipher type This patch adds the new type of block ciphers. Unlike current cipher algorithms which operate on a single block at a time, block ciphers operate on an arbitrarily long linear area of data. As it is block-based, it will skip any data remaining at the end which cannot form a block. The block cipher has one major difference when compared to the existing block cipher implementation. The sg walking is now performed by the algorithm rather than the cipher mid-layer. This is needed for drivers that directly support sg lists. It also improves performance for all algorithms as it reduces the total number of indirect calls by one. In future the existing cipher algorithm will be converted to only have a single-block interface. This will be done after all existing users have switched over to the new block cipher type.

It should be either on or off, i.e., built-in or disabled. This just happens to stop a potential runaway modprobe loop that seems to trigger on at least one distro. With fixes from Evgeniy Polyakov.

In struct cryptd_cpu_queue, a struct crypto_queue holds all requests for the CPU, a struct work_struct is used to run all requests for the CPU.

crypto: engine - Introduce the block request crypto engine framework Now block cipher engines need to implement and maintain their own queue/thread for processing requests, moreover currently helpers provided for only the queue itself (in crypto_enqueue_request() and crypto_dequeue_request()) but they don't help with the mechanics of driving the hardware (things like running the request immediately, DMA map it or providing a thread to process the queue in) even though a lot of that code really shouldn't vary that much from device to device. Thus this patch provides a mechanism for pushing requests to the hardware as it becomes free that drivers could use. And this framework is patterned on the SPI code and has worked out well there.

[CRYPTO] sha256-generic: Extend sha256_generic.c to support SHA-224 Resubmitting this patch which extends sha256_generic.c to support SHA-224 as described in FIPS 180-2 and RFC 3874. HMAC-SHA-224 as described in RFC4231 is then supported through the hmac interface. Patch includes test vectors for SHA-224 and HMAC-SHA-224. SHA-224 chould be chosen as a hash algorithm when 112 bits of security strength is required. Patch generated against the 2.6.24-rc1 kernel and tested against 2.6.24-rc1-git14 which includes fix for scatter gather implementation for HMAC.

This cleans up the code considerably, but more importantly, it allows the use of alternative CBC-MAC implementations that don't suffer from performance degradation due to significant setup time (e.g., the NEON based AES code needs to enable/disable the NEON, and load the S-box into 16 SIMD registers, which cannot be amortized over the entire input when using the cipher interface) Signed-off-by: Ard Biesheuvel <ard.biesheuvel@linaro.org> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

Nor can they switch to the new interface until IV generation is fully supported by it. So this means we are adding two versions of seqiv alongside the existing one. The first one is the one that will be used when the underlying AEAD algorithm has switched over to the new AEAD interface. The second one handles the current case where the underlying AEAD algorithm still uses the old interface. Both versions export themselves through the new AEAD interface.

[CRYPTO] lib: table driven multiplications in GF(2^128) A lot of cypher modes need multiplications in GF(2^128). LRW, ABL, GCM... I use functions from this library in my LRW implementation and I will also use them in my ABL (Arbitrary Block Length, an unencumbered (correct me if I am wrong, wide block cipher mode). Elements of GF(2^128) must be presented as u128 *, it encourages automatic and proper alignment. The library contains support for two different representations of GF(2^128), see the comment in gf128mul.h. There different levels of optimization (memory/speed tradeoff). The code is based on work by Dr Brian Gladman. Notable changes: - deletion of two optimization modes - change from u32 to u64 for faster handling on 64bit machines - support for 'bbe' representation in addition to the, already implemented, 'lle' representation. - move 'inline void' functions from header to 'static void' in the source file - update to use the linux coding style conventions The original can be found at: http://fp.gladman.plus.com/AES/modes.vc8.19-06-06.zip The copyright (and GPL statement) of the original author is preserved.

crypto: adiantum - add Adiantum support Add support for the Adiantum encryption mode. Adiantum was designed by Paul Crowley and is specified by our paper: Adiantum: length-preserving encryption for entry-level processors (https://eprint.iacr.org/2018/720.pdf) See our paper for full details; this patch only provides an overview. Adiantum is a tweakable, length-preserving encryption mode designed for fast and secure disk encryption, especially on CPUs without dedicated crypto instructions. Adiantum encrypts each sector using the XChaCha12 stream cipher, two passes of an ε-almost-∆-universal (εA∆U) hash function, and an invocation of the AES-256 block cipher on a single 16-byte block. On CPUs without AES instructions, Adiantum is much faster than AES-XTS; for example, on ARM Cortex-A7, on 4096-byte sectors Adiantum encryption is about 4 times faster than AES-256-XTS encryption, and decryption about 5 times faster. Adiantum is a specialization of the more general HBSH construction. Our earlier proposal, HPolyC, was also a HBSH specialization, but it used a different εA∆U hash function, one based on Poly1305 only. Adiantum's εA∆U hash function, which is based primarily on the "NH" hash function like that used in UMAC (RFC4418), is about twice as fast as HPolyC's; consequently, Adiantum is about 20% faster than HPolyC. This speed comes with no loss of security: Adiantum is provably just as secure as HPolyC, in fact slightly *more* secure. Like HPolyC, Adiantum's security is reducible to that of XChaCha12 and AES-256, subject to a security bound. XChaCha12 itself has a security reduction to ChaCha12. Therefore, one need not "trust" Adiantum; one need only trust ChaCha12 and AES-256. Note that the εA∆U hash function is only used for its proven combinatorical properties so cannot be "broken". Adiantum is also a true wide-block encryption mode, so flipping any plaintext bit in the sector scrambles the entire ciphertext, and vice versa. No other such mode is available in the kernel currently; doing the same with XTS scrambles only 16 bytes. Adiantum also supports arbitrary-length tweaks and naturally supports any length input >= 16 bytes without needing "ciphertext stealing". For the stream cipher, Adiantum uses XChaCha12 rather than XChaCha20 in order to make encryption feasible on the widest range of devices. Although the 20-round variant is quite popular, the best known attacks on ChaCha are on only 7 rounds, so ChaCha12 still has a substantial security margin; in fact, larger than AES-256's. 12-round Salsa20 is also the eSTREAM recommendation. For the block cipher, Adiantum uses AES-256, despite it having a lower security margin than XChaCha12 and needing table lookups, due to AES's extensive adoption and analysis making it the obvious first choice. Nevertheless, for flexibility this patch also permits the "adiantum" template to be instantiated with XChaCha20 and/or with an alternate block cipher. We need Adiantum support in the kernel for use in dm-crypt and fscrypt, where currently the only other suitable options are block cipher modes such as AES-XTS. A big problem with this is that many low-end mobile devices (e.g. Android Go phones sold primarily in developing countries, as well as some smartwatches) still have CPUs that lack AES instructions, e.g. ARM Cortex-A7. Sadly, AES-XTS encryption is much too slow to be viable on these devices. We did find that some "lightweight" block ciphers are fast enough, but these suffer from problems such as not having much cryptanalysis or being too controversial. The ChaCha stream cipher has excellent performance but is insecure to use directly for disk encryption, since each sector's IV is reused each time it is overwritten. Even restricting the threat model to offline attacks only isn't enough, since modern flash storage devices don't guarantee that "overwrites" are really overwrites, due to wear-leveling. Adiantum avoids this problem by constructing a "tweakable super-pseudorandom permutation"; this is the strongest possible security model for length-preserving encryption. Of course, storing random nonces along with the ciphertext would be the ideal solution. But doing that with existing hardware and filesystems runs into major practical problems; in most cases it would require data journaling (like dm-integrity) which severely degrades performance. Thus, for now length-preserving encryption is still needed.

Adiantum's security is provably reducible to that of its
underlying stream and block ciphers, subject to a security
bound. Unlike XTS, Adiantum is a true wide-block encryption
mode, so it actually provides an even stronger notion of
security than XTS, subject to the security bound.

[CRYPTO] ctr: Add CTR (Counter) block cipher mode This patch implements CTR mode for IPsec. It is based off of RFC 3686. Please note: 1. CTR turns a block cipher into a stream cipher. Encryption is done in blocks, however the last block may be a partial block. A "counter block" is encrypted, creating a keystream that is xor'ed with the plaintext. The counter portion of the counter block is incremented after each block of plaintext is encrypted. Decryption is performed in same manner. 2. The CTR counterblock is composed of, nonce + IV + counter The size of the counterblock is equivalent to the blocksize of the cipher. sizeof(nonce) + sizeof(IV) + sizeof(counter) = blocksize The CTR template requires the name of the cipher algorithm, the sizeof the nonce, and the sizeof the iv. ctr(cipher,sizeof_nonce,sizeof_iv) So for example, ctr(aes,4,8) specifies the counterblock will be composed of 4 bytes from a nonce, 8 bytes from the iv, and 4 bytes for counter since aes has a blocksize of 16 bytes. 3. The counter portion of the counter block is stored in big endian for conformance to rfc 3686. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

[CRYPTO] ctr: Add CTR (Counter) block cipher mode This patch implements CTR mode for IPsec. It is based off of RFC 3686. Please note: 1. CTR turns a block cipher into a stream cipher. Encryption is done in blocks, however the last block may be a partial block. A "counter block" is encrypted, creating a keystream that is xor'ed with the plaintext. The counter portion of the counter block is incremented after each block of plaintext is encrypted. Decryption is performed in same manner. 2. The CTR counterblock is composed of, nonce + IV + counter The size of the counterblock is equivalent to the blocksize of the cipher. sizeof(nonce) + sizeof(IV) + sizeof(counter) = blocksize The CTR template requires the name of the cipher algorithm, the sizeof the nonce, and the sizeof the iv. ctr(cipher,sizeof_nonce,sizeof_iv) So for example, ctr(aes,4,8) specifies the counterblock will be composed of 4 bytes from a nonce, 8 bytes from the iv, and 4 bytes for counter since aes has a blocksize of 16 bytes. 3. The counter portion of the counter block is stored in big endian for conformance to rfc 3686. Signed-off-by: Joy Latten <latten@austin.ibm.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

libcrc32c: Move implementation to crypto crc32c This patch swaps the role of libcrc32c and crc32c. Previously the implementation was in libcrc32c and crc32c was a wrapper. Now the code is in crc32c and libcrc32c just calls the crypto layer. The reason for the change is to tap into the algorithm selection capability of the crypto API so that optimised implementations such as the one utilising Intel's CRC32C instruction can be used where available.

Poly1305 authenticator algorithm, RFC7539.
Poly1305 is an authenticator algorithm designed by Daniel J. Bernstein.
It is used for the ChaCha20-Poly1305 AEAD, specified in RFC7539 for use
in IETF protocols. This is the portable C implementation of Poly1305.
crypto: poly1305 - Add a SSE2 SIMD variant for x86_64 Implements an x86_64 assembler driver for the Poly1305 authenticator.

RIPEMD-160 is a 160-bit cryptographic hash function. It is intended
to be used as a secure replacement for the 128-bit hash functions
MD4, MD5 and it's predecessor RIPEMD
(not to be confused with RIPEMD-128).

RIPEMD-256 is an optional extension of RIPEMD-128 with a
256 bit hash. It is intended for applications that require
longer hash-results, without needing a larger security level
(than RIPEMD-128).

crypto: sha1 - SSSE3 based SHA1 implementation for x86-64 This is an assembler implementation of the SHA1 algorithm using the Supplemental SSE3 (SSSE3) instructions or, when available, the Advanced Vector Extensions (AVX). Testing with the tcrypt module shows the raw hash performance is up to 2.3 times faster than the C implementation, using 8k data blocks on a Core 2 Duo T5500. For the smalest data set (16 byte) it is still 25% faster. Since this implementation uses SSE/YMM registers it cannot safely be used in every situation, e.g. while an IRQ interrupts a kernel thread. The implementation falls back to the generic SHA1 variant, if using the SSE/YMM registers is not possible. With this algorithm I was able to increase the throughput of a single IPsec link from 344 Mbit/s to 464 Mbit/s on a Core 2 Quad CPU using the SSSE3 variant -- a speedup of +34.8%. Saving and restoring SSE/YMM state might make the actual throughput fluctuate when there are FPU intensive userland applications running. For example, meassuring the performance using iperf2 directly on the machine under test gives wobbling numbers because iperf2 uses the FPU for each packet to check if the reporting interval has expired (in the above test I got min/max/avg: 402/484/464 MBit/s). Using this algorithm on a IPsec gateway gives much more reasonable and stable numbers, albeit not as high as in the directly connected case. Here is the result from an RFC 2544 test run with a EXFO Packet Blazer FTB-8510: frame size sha1-generic sha1-ssse3 delta 64 byte 37.5 MBit/s 37.5 MBit/s 0.0% 128 byte 56.3 MBit/s 62.5 MBit/s +11.0% 256 byte 87.5 MBit/s 100.0 MBit/s +14.3% 512 byte 131.3 MBit/s 150.0 MBit/s +14.2% 1024 byte 162.5 MBit/s 193.8 MBit/s +19.3% 1280 byte 175.0 MBit/s 212.5 MBit/s +21.4% 1420 byte 175.0 MBit/s 218.7 MBit/s +25.0% 1518 byte 150.0 MBit/s 181.2 MBit/s +20.8% The throughput for the largest frame size is lower than for the previous size because the IP packets need to be fragmented in this case to make there way through the IPsec tunnel.

[CRYPTO] twofish: Split out common c code This patch splits up the twofish crypto routine into a common part ( key setup ) which will be uses by all twofish crypto modules ( generic-c , i586 assembler and x86_64 assembler ) and generic-c part. It also creates a new header file which will be used by all 3 modules. This eliminates all code duplication. Correctness was verified with the tcrypt module and automated test scripts.

crypto: aes - add generic time invariant AES cipher Lookup table based AES is sensitive to timing attacks, which is due to the fact that such table lookups are data dependent, and the fact that 8 KB worth of tables covers a significant number of cachelines on any architecture, resulting in an exploitable correlation between the key and the processing time for known plaintexts. For network facing algorithms such as CTR, CCM or GCM, this presents a security risk, which is why arch specific AES ports are typically time invariant, either through the use of special instructions, or by using SIMD algorithms that don't rely on table lookups. For generic code, this is difficult to achieve without losing too much performance, but we can improve the situation significantly by switching to an implementation that only needs 256 bytes of table data (the actual S-box itself), which can be prefetched at the start of each block to eliminate data dependent latencies. This code encrypts at ~25 cycles per byte on ARM Cortex-A57 (while the ordinary generic AES driver manages 18 cycles per byte on this hardware). Decryption is substantially slower.

This is a generic implementation of AES that attempts to eliminate
data dependent latencies as much as possible without affecting
performance too much. It is intended for use by the generic CCM
and GCM drivers, and other CTR or CMAC/XCBC based modes that rely
solely on encryption (although decryption is supported as well, but
with a more dramatic performance hit)
Instead of using 16 lookup tables of 1 KB each, (8 for encryption and
8 for decryption), this implementation only uses just two S-boxes of
256 bytes each, and attempts to eliminate data dependent latencies by
prefetching the entire table into the cache at the start of each
crypto: aes_ti - disable interrupts while accessing S-box In the "aes-fixed-time" AES implementation, disable interrupts while accessing the S-box, in order to make cache-timing attacks more difficult. Previously it was possible for the CPU to be interrupted while the S-box was loaded into L1 cache, potentially evicting the cachelines and causing later table lookups to be time-variant. In tests I did on x86 and ARM, this doesn't affect performance significantly. Responsiveness is potentially a concern, but interrupts are only disabled for a single AES block. Note that even after this change, the implementation still isn't necessarily guaranteed to be constant-time; see https://cr.yp.to/antiforgery/cachetiming-20050414.pdf for a discussion of the many difficulties involved in writing truly constant-time AES software. But it's valuable to make such attacks more difficult.

are evicted when the CPU is interrupted to do something else.

[CRYPTO] Add x86_64 asm AES Implementation: =============== The encrypt/decrypt code is based on an x86 implementation I did a while ago which I never published. This unpublished implementation does include an assembler based key schedule and precomputed tables. For simplicity and best acceptance, however, I took Gladman's in-kernel code for table generation and key schedule for the kernel port of my assembler code and modified this code to produce the key schedule as required by my assembler implementation. File locations and Kconfig are kept similar to the i586 AES assembler implementation. It may seem a little bit strange to use 32 bit I/O and registers in the assembler implementation but this gives the best code size. My implementation takes one instruction more per round compared to Gladman's x86 assembler but it doesn't require any stack for local variables or saved registers and it is less serialized than Gladman's code. Note that all comparisons to Gladman's code were done after my code was implemented. I did only use FIPS PUB 197 for the implementation so my implementation is independent work. If anybody has a better assembler solution for x86_64 I'll be pleased to have my code replaced with the better solution. Testing: ======== The implementation passes the in-kernel crypto testing module and I'm running it without any problems on my laptop where it is mainly used for dm-crypt. Microbenchmark: =============== The microbenchmark was done in userspace with similar compile flags as used during kernel compile. Encrypt/decrypt is about 35% faster than the generic C implementation. As the generic C as well as my assembler implementation are both table I don't really expect that there is much room for further improvements though I'll be glad to be corrected here. The key schedule is about 5% slower than the generic C implementation. This is due to the fact that some more work has to be done in the key schedule routine to fit the schedule to the assembler implementation. Code Size: ========== Encrypt and decrypt are together about 2.1 Kbytes smaller than the generic C implementation which is important with regard to L1 cache usage. The key schedule routine is about 100 bytes larger than the generic C implementation. Data Size: ========== There's no difference in data size requirements between the assembler implementation and the generic C implementation.

crypto: aes-ni - Add support to Intel AES-NI instructions for x86_64 platform Intel AES-NI is a new set of Single Instruction Multiple Data (SIMD) instructions that are going to be introduced in the next generation of Intel processor, as of 2009. These instructions enable fast and secure data encryption and decryption, using the Advanced Encryption Standard (AES), defined by FIPS Publication number 197.

[CRYPTO] Add x86_64 asm AES Implementation: =============== The encrypt/decrypt code is based on an x86 implementation I did a while ago which I never published. This unpublished implementation does include an assembler based key schedule and precomputed tables. For simplicity and best acceptance, however, I took Gladman's in-kernel code for table generation and key schedule for the kernel port of my assembler code and modified this code to produce the key schedule as required by my assembler implementation. File locations and Kconfig are kept similar to the i586 AES assembler implementation. It may seem a little bit strange to use 32 bit I/O and registers in the assembler implementation but this gives the best code size. My implementation takes one instruction more per round compared to Gladman's x86 assembler but it doesn't require any stack for local variables or saved registers and it is less serialized than Gladman's code. Note that all comparisons to Gladman's code were done after my code was implemented. I did only use FIPS PUB 197 for the implementation so my implementation is independent work. If anybody has a better assembler solution for x86_64 I'll be pleased to have my code replaced with the better solution. Testing: ======== The implementation passes the in-kernel crypto testing module and I'm running it without any problems on my laptop where it is mainly used for dm-crypt. Microbenchmark: =============== The microbenchmark was done in userspace with similar compile flags as used during kernel compile. Encrypt/decrypt is about 35% faster than the generic C implementation. As the generic C as well as my assembler implementation are both table I don't really expect that there is much room for further improvements though I'll be glad to be corrected here. The key schedule is about 5% slower than the generic C implementation. This is due to the fact that some more work has to be done in the key schedule routine to fit the schedule to the assembler implementation. Code Size: ========== Encrypt and decrypt are together about 2.1 Kbytes smaller than the generic C implementation which is important with regard to L1 cache usage. The key schedule routine is about 100 bytes larger than the generic C implementation. Data Size: ========== There's no difference in data size requirements between the assembler implementation and the generic C implementation. License: ======== Gladmans's code is dual BSD/GPL whereas my assembler code is GPLv2 only (I'm not going to change the license for my code). So I had to change the module license for the x86_64 aes module from 'Dual BSD/GPL' to 'GPL' to reflect the most restrictive license within the module.

crypto: x86/aes-ni - remove special handling of AES in PCBC mode For historical reasons, the AES-NI based implementation of the PCBC chaining mode uses a special FPU chaining mode wrapper template to amortize the FPU start/stop overhead over multiple blocks. When this FPU wrapper was introduced, it supported widely used chaining modes such as XTS and CTR (as well as LRW), but currently, PCBC is the only remaining user. Since there are no known users of pcbc(aes) in the kernel, let's remove this special driver, and rely on the generic pcbc driver to encapsulate the AES-NI core cipher.

crypto: aes-ni - Add support for more modes Because kernel_fpu_begin() and kernel_fpu_end() operations are too slow, the performance gain of general mode implementation + aes-aesni is almost all compensated. The AES-NI support for more modes are implemented as follow: - Add a new AES algorithm implementation named __aes-aesni without kernel_fpu_begin/end() - Use fpu(<mode>(AES)) to provide kenrel_fpu_begin/end() invoking - Add <mode>(AES) ablkcipher, which uses cryptd(fpu(<mode>(AES))) to defer cryption to cryptd context in soft_irq context. Now the ctr, lrw, pcbc and xts support are added. Performance testing based on dm-crypt shows that cryption time can be reduced to 50% of general mode implementation + aes-aesni implementation.

crypto: camellia - add assembler implementation for x86_64 Patch adds x86_64 assembler implementation of Camellia block cipher. Two set of functions are provided. First set is regular 'one-block at time' encrypt/decrypt functions. Second is 'two-block at time' functions that gain performance increase on out-of-order CPUs. Performance of 2-way functions should be equal to 1-way functions with in-order CPUs. Patch has been tested with tcrypt and automated filesystem tests.

Compared to AVX implementation, this version is extended to use the 256-bit wide YMM registers. For AES-NI instructions data is split to two 128-bit registers and merged afterwards. Even with this additional handling, performance should be higher compared to the AES-NI/AVX implementation.

We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!

crypto: chacha - add XChaCha12 support Now that the generic implementation of ChaCha20 has been refactored to allow varying the number of rounds, add support for XChaCha12, which is the XSalsa construction applied to ChaCha12. ChaCha12 is one of the three ciphers specified by the original ChaCha paper (https://cr.yp.to/chacha/chacha-20080128.pdf: "ChaCha, a variant of Salsa20"), alongside ChaCha8 and ChaCha20. ChaCha12 is faster than ChaCha20 but has a lower, but still large, security margin. We need XChaCha12 support so that it can be used in the Adiantum encryption mode, which enables disk/file encryption on low-end mobile devices where AES-XTS is too slow as the CPUs lack AES instructions. We'd prefer XChaCha20 (the more popular variant), but it's too slow on some of our target devices, so at least in some cases we do need the XChaCha12-based version. In more detail, the problem is that Adiantum is still much slower than we're happy with, and encryption still has a quite noticeable effect on the feel of low-end devices. Users and vendors push back hard against encryption that degrades the user experience, which always risks encryption being disabled entirely. So we need to choose the fastest option that gives us a solid margin of security, and here that's XChaCha12. The best known attack on ChaCha breaks only 7 rounds and has 2^235 time complexity, so ChaCha12's security margin is still better than AES-256's. Much has been learned about cryptanalysis of ARX ciphers since Salsa20 was originally designed in 2005, and it now seems we can be comfortable with a smaller number of rounds. The eSTREAM project also suggests the 12-round version of Salsa20 as providing the best balance among the different variants: combining very good performance with a "comfortable margin of security". Note that it would be trivial to add vanilla ChaCha12 in addition to XChaCha12. However, it's unneeded for now and therefore is omitted. As discussed in the patch that introduced XChaCha20 support, I considered splitting the code into separate chacha-common, chacha20, xchacha20, and xchacha12 modules, so that these algorithms could be enabled/disabled independently. However, since nearly all the code is shared anyway, I ultimately decided there would have been little benefit to the added complexity.

Bernstein and further specified in RFC7539 for use in IETF protocols.
crypto: chacha20-generic - add XChaCha20 support Add support for the XChaCha20 stream cipher. XChaCha20 is the application of the XSalsa20 construction (https://cr.yp.to/snuffle/xsalsa-20081128.pdf) to ChaCha20 rather than to Salsa20. XChaCha20 extends ChaCha20's nonce length from 64 bits (or 96 bits, depending on convention) to 192 bits, while provably retaining ChaCha20's security. XChaCha20 uses the ChaCha20 permutation to map the key and first 128 nonce bits to a 256-bit subkey. Then, it does the ChaCha20 stream cipher with the subkey and remaining 64 bits of nonce. We need XChaCha support in order to add support for the Adiantum encryption mode. Note that to meet our performance requirements, we actually plan to primarily use the variant XChaCha12. But we believe it's wise to first add XChaCha20 as a baseline with a higher security margin, in case there are any situations where it can be used. Supporting both variants is straightforward. Since XChaCha20's subkey differs for each request, XChaCha20 can't be a template that wraps ChaCha20; that would require re-keying the underlying ChaCha20 for every request, which wouldn't be thread-safe. Instead, we make XChaCha20 its own top-level algorithm which calls the ChaCha20 streaming implementation internally. Similar to the existing ChaCha20 implementation, we define the IV to be the nonce and stream position concatenated together. This allows users to seek to any position in the stream. I considered splitting the code into separate chacha20-common, chacha20, and xchacha20 modules, so that chacha20 and xchacha20 could be enabled/disabled independently.

crypto: serpent - add x86_64/avx assembler implementation This patch adds a x86_64/avx assembler implementation of the Serpent block cipher. The implementation is very similar to the sse2 implementation and processes eight blocks in parallel.

The construction is done by concatenating the encrypted result from the cipher with the output from the hash, as is used by the IPsec ESP protocol. The authenc algorithm exists as a template with four parameters: authenc(auth, authsize, enc, enckeylen). The authentication algorithm, the authentication size (i.e., truncating the output of the authentication algorithm), the encryption algorithm, and the encryption key length. Both the size field and the key length field are in bytes. For example, AES-128 with SHA1-HMAC would be represented by authenc(hmac(sha1), 12, cbc(aes), 16) The key for the authenc algorithm is the concatenation of the keys for the authentication algorithm with the encryption algorithm. For the above example, if a key of length 36 bytes is given, then hmac(sha1) would receive the first 20 bytes while the last 16 would be given to cbc(aes).

IPSec with the IPCOMP protocol (RFC3173, RFC2394).
You will most probably want this if using IPSec.

This should not fall back to any other compression method, however; users of this crypto compression alg can fallback if desired, and transparent fallback tricks callers into thinking they are getting 842 compression when they actually get LZO compression - the failure of the 842 hardware should not be transparent to the caller.

crypto: drbg - use CTR AES instead of ECB AES The CTR DRBG derives its random data from the CTR that is encrypted with AES. This patch now changes the CTR DRBG implementation such that the CTR AES mode is employed. This allows the use of steamlined CTR AES implementation such as ctr-aes-aesni. Unfortunately there are the following subtile changes we need to apply when using the CTR AES mode: - the CTR mode increments the counter after the cipher operation, but the CTR DRBG requires the increment before the cipher op. Hence, the crypto_inc is applied to the counter (drbg->V) once it is recalculated. - the CTR mode wants to encrypt data, but the CTR DRBG is interested in the encrypted counter only. The full CTR mode is the XOR of the encrypted counter with the plaintext data. To access the encrypted counter, the patch uses a NULL data vector as plaintext to be "encrypted".

crypto: af_alg - User-space interface for Crypto API This patch creates the backbone of the user-space interface for the Crypto API, through a new socket family AF_ALG. Each session corresponds to one or more connections obtained from that socket. The number depends on the number of inputs/outputs of that particular type of operation. For most types there will be a s ingle connection/file descriptor that is used for both input and output. AEAD is one of the few that require two inputs. Each algorithm type will provide its own implementation that plugs into af_alg. They're keyed using a string such as "skcipher" or "hash".

crypto: algif_skcipher - User-space interface for skcipher operations This patch adds the af_alg plugin for symmetric key ciphers, corresponding to the ablkcipher kernel operation type. Keys can optionally be set through the setsockopt interface. Once a sendmsg call occurs without MSG_MORE no further writes may be made to the socket until all previous data has been read. IVs and and whether encryption/decryption is performed can be set through the setsockopt interface or as a control message to sendmsg. The interface is completely synchronous, all operations are carried out in recvmsg(2) and will complete prior to the system call returning. The splice(2) interface support reading the user-space data directly without copying (except that the Crypto API itself may copy the data if alignment is off). The recvmsg(2) interface supports directly writing to user-space without additional copying, i.e., the kernel crypto interface will receive the user-space address as its output SG list.

crypto: algif_aead - copy AAD from src to dst Use the NULL cipher to copy the AAD and PT/CT from the TX SGL to the RX SGL. This allows an in-place crypto operation on the RX SGL for encryption, because the TX data is always smaller or equal to the RX data (the RX data will hold the tag). For decryption, a per-request TX SGL is created which will only hold the tag value. As the RX SGL will have no space for the tag value and an in-place operation will not write the tag buffer, the TX SGL with the tag value is chained to the RX SGL. This now allows an in-place crypto operation.

treewide: surround Kconfig file paths with double quotes The Kconfig lexer supports special characters such as '.' and '/' in the parameter context. In my understanding, the reason is just to support bare file paths in the source statement. I do not see a good reason to complicate Kconfig for the room of ambiguity. The majority of code already surrounds file paths with double quotes, and it makes sense since file paths are constant string literals. Make it treewide consistent now.

[CRYPTO] api: Split out low-level API The crypto API is made up of the part facing users such as IPsec and the low-level part which is used by cryptographic entities such as algorithms. This patch splits out the latter so that the two APIs are more clearly delineated. As a bonus the low-level API can now be modularised if all algorithms are built as modules.
