This backports commits from master that fix AES ciphers when using the qce driver: - A couple of simple fixes for CTR and XTS modes used with AES: * 041-crypto-qce-fix-ctr-aes-qce-block-chunk-sizes.patch * 042-crypto-qce-fix-xts-aes-qce-key-sizes.patch - A fix for a bug that affected cases when there were more entries in the input sg list than necessary to actually encrypt, resulting in failure in gcm, where the authentication tag is present after the encryption data: * 043-crypto-qce-save-a-sg-table-slot-for-result-buf.patch - A fix to update the IV buffer passed to the driver from the kernel: * 044-crypto-qce-update-the-skcipher-IV.patch - A patch that reduces memory footprint and driver initialization by only initializing the fallback mechanism where it is actually used: * 046-crypto-qce-initialize-fallback-only-for-AES.patch - Three patches that make gcm and xts modes work with the qce driver, and improve performance with small blocks: * 047-crypto-qce-use-cryptlen-when-adding-extra-sgl.patch * 048-crypto-qce-use-AES-fallback-for-small-requests.patch * 049-crypto-qce-handle-AES-XTS-cases-that-qce-fails.patch - A patch that allows the hashes/ciphers to be built individually. * 051-crypto-qce-allow-building-only-hashes-ciphers.patch Signed-off-by: Eneas U de Queiroz <cotequeiroz@gmail.com> [renumbered patches, added patches from dropped commit, refreshed, 5.4] Signed-off-by: Christian Lamparter <chunkeey@gmail.com>
