hwrng: xilinx - Move xilinx-rng into drivers/char/hw_random/

2026-06-12T01:56:26+00:00

Since this file just implements a hwrng driver, move it into drivers/char/hw_random/. Rename the kconfig option accordingly as well. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: xilinx-trng - Replace crypto_drbg_ctr_df() with HMAC-SHA512

2026-06-11T06:03:13+00:00

This code is just trying to condition 48 bytes of random data. This can be done easily using HKDF-SHA512-Extract, saving 300 lines of code. This commit also fixes forward security (in this particular case) by clearing the entropy from memory after it's used. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: xilinx-trng - Fix return value of xtrng_hwrng_trng_read()

2026-06-11T06:03:13+00:00

Implementations of hwrng::read are expected to return the number of bytes generated. Update xtrng_hwrng_trng_read() to match that. Fixes: 8979744aca80 ("crypto: xilinx - Add TRNG driver for Versal") Cc: stable@vger.kernel.org Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu

crypto: xilinx-trng - Remove crypto_rng interface

2026-06-11T06:03:13+00:00

Implementing the crypto_rng interface has no purpose, as it isn't used in practice. It's being removed from other drivers too. Just remove it. This leaves hwrng, which is actually used. Tagging with 'Cc stable' due to the bugs that this removes: - xtrng_trng_generate() sometimes returned success even when it didn't fill in all the bytes. - It was possible for xtrng_trng_generate() and xtrng_hwrng_trng_read() to run concurrently and interfere with each other, as the locking code in xtrng_hwrng_trng_read() was broken.

crypto: drbg - Eliminate use of 'drbg_string' and lists

2026-05-07T08:10:01+00:00

Use straightforward (buffer, len) parameters instead of struct drbg_string or lists of strings. This simplifies the code considerably. For now struct drbg_string is still used in crypto_drbg_ctr_df(), so move its definition to crypto/df_sp80090a.h. Signed-off-by: Eric Biggers Signed-off-by: Herbert Xu
