Crypto/chcr: fix for ccm(aes) failed test

2020-06-20T08:25:11+00:00

[ Upstream commit 10b0c75d7bc19606fa9a62c8ab9180e95c0e0385 ] The ccm(aes) test fails when req->assoclen > ~240bytes. The problem is the value assigned to auth_offset is wrong. As auth_offset is unsigned char, it can take max value as 255. So fix it by making it unsigned int. Signed-off-by: Ayush Sawal Signed-off-by: Devulapally Shiva Krishna Signed-off-by: David S.

crypto: chelsio - fix writing tfm flags to wrong place

2020-02-05T14:18:03+00:00

commit bd56cea012fc2d6381e8cd3209510ce09f9de8c9 upstream. The chelsio crypto driver is casting 'struct crypto_aead' directly to 'struct crypto_tfm', which is incorrect because the crypto_tfm isn't the first field of 'struct crypto_aead'. Consequently, the calls to crypto_tfm_set_flags() are modifying some other field in the struct. Also, the driver is setting CRYPTO_TFM_RES_BAD_KEY_LEN in ->setauthsize(), not just in ->setkey(). This is incorrect since this flag is for bad key lengths, not for bad authentication tag lengths. Fix these bugs by removing the broken crypto_tfm_set_flags() calls from ->setauthsize() and by fixing them in ->setkey().

crypto: chelsio - Fix memory corruption in DMA Mapped buffers.

2018-10-13T07:27:28+00:00

commit add92a817e60e308a419693413a38d9d1e663aff upstream. Update PCI Id in "cpl_rx_phys_dsgl" header. In case pci_chan_id and tx_chan_id are not derived from same queue, H/W can send request completion indication before completing DMA Transfer. Herbert, It would be good if fix can be merge to stable tree. For 4.14 kernel, It requires some update to avoid mege conficts.

crypto: chelsio - select CRYPTO_GF128MUL

commit d042566d8c704e1ecec370300545d4a409222e39 upstream. Without the gf128mul library support, we can run into a link error: drivers/crypto/chelsio/chcr_algo.o: In function `chcr_update_tweak': chcr_algo.c:(.text+0x7e0): undefined reference to `gf128mul_x8_ble' This adds a Kconfig select statement for it, next to the ones we already have.
