crypto: starfive - Correctly handle return of sg_nents_for_len

2026-01-11T14:21:29+00:00

[ Upstream commit e9eb52037a529fbb307c290e9951a62dd728b03d ] The return value of sg_nents_for_len was assigned to an unsigned long in starfive_hash_digest, causing negative error codes to be converted to large positive integers. Add error checking for sg_nents_for_len and return immediately on failure to prevent potential buffer overflows.

crypto: starfive - Fix nent assignment in rsa dec

2024-09-12T09:11:43+00:00

[ Upstream commit 8323c036789b8b4a61925fce439a89dba17b7f2f ] Missing src scatterlist nent assignment in rsa decrypt function. Removing all unneeded assignment and use nents value from req->src instead. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu Signed-off-by: Sasha Levin

crypto: starfive - Align rsa input data to 32-bit

2024-09-12T09:11:43+00:00

[ Upstream commit 6aad7019f697ab0bed98eba737d19bd7f67713de ] Hardware expects RSA input plain/ciphertext to be 32-bit aligned. Set fixed length for preallocated buffer to the maximum supported keysize of the hardware and shift input text accordingly.

crypto: starfive - Fix dev_err_probe return error

2024-02-05T20:14:16+00:00

[ Upstream commit 8517c34e87025b3f74f3c07813d493828f369598 ] Current dev_err_probe will return 0 instead of proper error code if driver failed to get irq number. Fix the return code. Signed-off-by: Jia Jie Ho Signed-off-by: Herbert Xu Signed-off-by: Sasha Levin

crypto: jh7110 - Correct deferred probe return

2024-01-25T23:35:15+00:00

[ Upstream commit d57343022b71b9f41e731282dbe0baf0cff6ada8 ] This fixes list_add corruption error when the driver is returned with -EPROBE_DEFER. It is also required to roll back the previous probe sequences in case of deferred_probe. So, this removes 'err_probe_defer" goto label and just use err_dma_init instead.

crypto: drivers - Explicitly include correct DT includes

2023-08-23T03:04:23+00:00

The DT of_device.h and of_platform.h date back to the separate of_platform_bus_type before it as merged into the regular platform bus. As part of that merge prepping Arm DT support 13 years ago, they "temporarily" include each other. They also include platform_device.h and of.h. As a result, there's a pretty much random mix of those include files used throughout the tree. In order to detangle these headers and replace the implicit includes with struct declarations, users need to explicitly include the correct includes.

crypto: jh7110 - Use new crypto_engine_op interface

2023-08-18T09:01:11+00:00

Use the new crypto_engine_op interface where the callback is stored in the algorithm object. Signed-off-by: Herbert Xu

crypto: jh7110 - Include scatterwalk.h for struct scatter_walk

2023-08-18T09:01:10+00:00

Include crypto/scatterwalk.h explicitly instead of getting it through random header files. Signed-off-by: Herbert Xu

crypto: jh7110 - Include crypto/hash.h in header file

2023-08-18T09:01:10+00:00

The header file jh7110-cryp uses ahash_request without including crypto/hash.h. Fix that by adding the inclusion. Signed-off-by: Herbert Xu

crypto: jh1100 - Remove prepare/unprepare request

2023-08-18T09:01:09+00:00

The callbacks for prepare and unprepare request in crypto_engine is superfluous. They can be done directly from do_one_request. Move the code into do_one_request and remove the unused callbacks. Signed-off-by: Herbert Xu
