* ltq-deu: aes: do not read/write behind bufferMathias Kresin2022-01-051-12/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Kresin2022-01-052-3/+2
| | | | | | | | | | | | | | 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.

* lantiq: kernel 5.10: disable ltq-deuMathias Kresin2021-04-121-1/+1
| | | | | | | | | | For linux 5.10, kmod-ltq-deu need to be migrated to the new crypto API/framework. Leave it in tree for now and enable it only for Kernel 5.4. Maybe someone picks up the work to migrate the package. Signed-off-by: Mathias Kresin <dev@kresin.me>
* kernel: drop outdated kernel version switches for local codeAdrian Schmutzler2020-05-176-51/+0
| | | | | | | | 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 Blumenstingl2020-03-164-4/+4
| | | | | | | | | | 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>
* build: include BUILD_VARIANT in PKG_BUILD_DIRJeffery To2019-08-051-1/+0
| | | | | | | | | | | This changes the default PKG_BUILD_DIR to take BUILD_VARIANT into account (if set), so that packages do not need to manually override PKG_BUILD_DIR just to handle variants. This also updates most base packages with variants to use the updated default PKG_BUILD_DIR. Signed-off-by: Jeffery To <jeffery.to@gmail.com>

* ltq-deu: fix cra_priorityMartin Schiller2016-08-209-8/+25
| | | | | | | | | | With the default priority of 0, the DEU algos would be overlapped by the generic algos (if available). To fix this, set the cra_priority of the hardware algos to the recommended value of 300/400. Signed-off-by: Martin Schiller <mschiller@tdt.de>

* lantiq: ltq-deu: Remove the "DEU test manager"Felix Fietkau2016-01-183-13561/+0
| | | | | | | | | | | 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). This fixes compilation on kernel 4.3, which removes aead_request_set_assoc (and newer kernels). Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> SVN-Revision: 48308

This also works with older kernels (at least 4.1, thanks to Hauke Mehrtens for testing). Signed-off-by: Martin Blumenstingl <martin.blumenstingl@googlemail.com> SVN-Revision: 48282
