* ltq-deu: fix cryptomgr test errors for desDaniel Kestrel2022-01-06
| | | | | | | | | | | | | | | | | | | | | | When running cryptomgr tests against the driver, there are several occurences of different errors for setkey of des and des3-ede algorithms. Those key checks are already implemented in the kernels des implementation, so this is added as dependency and the kernel methods are called. It also required adding the kernels des/des3 context definitions to the des_ctx internal structure to be able to call the kernel methods. Fixed ifxdeu-des... setkey unexpectedly succeeded on test vector x; expected_error=-22. Fixed ifxdeu-des... setkey failed on test vector x; expected_error=0, actual_error=-22. Renamed des_ctx internal structure and des_encrypt/des_decrypt methods because they are already defined in the kernel module. Fixed wrong DES_xxx constant definitions in crypto_alg definition for ifxdeu_des3_ede_alg. Fixed method comment errors. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de>
* ltq-deu: convert SHA1 after library impl of SHA1 was removedDaniel Kestrel2022-01-06
| | | | | | | | | The <linux/cryptohash.h> was removed with Linux 5.8, because it only contained the library implementation of SHA1, which was folded into <crypto/sha.h>. So switch this driver away from using <linux/cryptohash.h>. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de>
* ltq-deu: convert blkcipher to skcipherDaniel Kestrel2022-01-06
| | | | | | | | | Convert blkcipher to skcipher for the synchronous versions of AES, DES and ARC4. The Block Cipher API was depracated for a while and was removed with Linux 5.5. So switch this driver to the skcipher API. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de>
* ltq-deu: set correct control register for AESDaniel Kestrel2022-01-06
| | | | | | | | | | | | Some devices initialize AES during boot and AES works out of the box and the correct endianess is set. NDC means (No Danube Compatibility Mode) and the endianess setting has no effect if its set to 0. NDC 0: OFF ENDI bit cannot be written as in Danube To make it work for other devices, the NDC control register needs to be set to 1. Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de>
* ltq-deu: make cipher/digest usable by opensslMathias Kresin2022-01-05
| | | | | | | | | | OpenSSL with cryptdev support uses the data encryption unit (DEU) driver for hard accelerated processing of ciphers/digests, if the flag CRYPTO_ALG_KERN_DRIVER_ONLY is set.

* ltq-deu: aes-ctr: process all input dataMathias Kresin2022-01-05
| | | | | | | | | | | | | | | | | | | | | | | Even if the minimum blocksize is set to 16 (AES_BLOCK_SIZE), the crypto manager tests pass 499 bytes of data to the aes-ctr encryption, from which only 496 bytes are actually encrypted. Reading the comment regarding the minimum blocksize, it only states that it's the "smallest possible unit which can be transformed with this algorithm". Which doesn't necessarily mean, the data have to be a multiple of the minimal blocksize. All kernel hardware crypto driver enforce a minimum blocksize of 1, which perfect fine works for the lantiq data encryption unit as well. Lower the blocksize limit to 1, to process not padded data as well. In AES for processing the remaining bytes, uninitialized pointers were used. This patch fixes using uninitialized pointers and wrong offsets. Signed-off-by: Mathias Kresin <dev@kresin.me> [fix commit title prefix] Signed-off-by: Daniel Kestrel <kestrel1974@t-online.de>
* ltq-deu: aes: do not read/write behind bufferMathias Kresin2022-01-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When handling non-aligned remaining data (not padded to 16 byte [AES_BLOCK_SIZE]), a full 16 byte block is read from the input buffer and written to the output buffer after en-/decryption. While code already assumes that an input buffer could have less than 16 byte remaining, as it can be seen by the code zeroing the remaining bytes till AES_BLOCK_SIZE, the full AES_BLOCK_SIZE is read. An output buffer size of a multiple of AES_BLOCK_SIZE is expected but never validated. To get rid of the read/write behind buffer, use a temporary buffer when dealing with not padded data and only write as much bytes to the output as we read. Do not memcpy directly to the register, to make used of the endian swap macro and to trigger the crypto start operator via the ID0R to trigger the register. Since we might need an endian swap for the output in future, use a temporary buffer for the output as well. The issue could not be observed so far, since all caller of ifx_deu_aes will ignore the padded (remaining) data. Considering that the minimum blocksize for the algorithm is set to AES_BLOCK_SIZE, the behaviour could be called expected.

* ltq-deu: init des/aes before registering crpyto algorithmsMathias Kresin2022-01-05
| | | | | | | | | | | | | | The crypto algorithms are registered and available to the system before the chip is actually powered on and the generic parameter for the DEU behaviour set. The issue can mainly be observed if the crypto manager tests are enabled in the kernel config. The crypto manager test run directly after an algorithm is registered.

* kernel: drop outdated kernel version switches for local codeAdrian Schmutzler2020-05-17
| | | | | | | | This drops kernel version switches for versions not supported by OpenWrt master at the moment. This only adjusts local code, but doesn't touch patches to existing external packages. Signed-off-by: Adrian Schmutzler <freifunk@adrianschmutzler.de>
* lantiq: ltq-deu: fix compatibility with Linux 5.3+Martin Blumenstingl2020-03-16
| | | | | | | | | | Upstream commit 84ede58dfcd1d ("crypto: hash - remove CRYPTO_ALG_TYPE_DIGEST") drops the CRYPTO_ALG_TYPE_DIGEST define because it has the same value as CRYPTO_ALG_TYPE_HASH. This was the case for earlier kernels as well. Switch to CRYPTO_ALG_TYPE_HASH to fix building against Linux 5.4. Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com>

| | | | | | | | | | | Remove the "DEU test manager" code which has not been used for more than two years (as the kernel module is not installed anymore since r38731).
