I built a 6.16-rc1 kernel [1] and its config is based upon Debian's and that has enabled CRYPTO_SELFTESTS [2] (due to Debian bug 599441 [3]). I then installed it on 3 Rockchip based devices and booted into that. 1. Radxa Rock 5B (rk3588) 2. PINE64 Quartz64 Model B (rk3568) 3. PINE64 RockPro64 (rk3399) The full dmesg output for level 0-4 can be found at [4], [5] and [6] The filtered dmesg output for Rock 5B: ERROR: [ 0.709822] basic hdkf test(hmac(sha256)): failed to allocate transform:= -2 WARNING: [ 0.710686] alg: full crypto tests enabled. This is intended for develo= per use only. [ 8.877288] alg: skcipher: skipping comparison tests for xctr-aes-ce bec= ause xctr(aes-generic) is unavailable The filtered dmesg output for Quartz64-B: ERROR: [ 1.479206] basic hdkf test(hmac(sha256)): failed to allocate transform:= -2 WARNING: [ 1.480685] alg: full crypto tests enabled.

[ 18.176195] alg: skcipher: skipping comparison tests for xctr-aes-ce bec= ause xctr(aes-generic) is unavailable For both of these, 1 warning is to be expected (developer use only). But I do wonder about the error and the other warning. Is that a problem? And if so, is that on the crypto or the Rockchip side? But the filtered dmesg output on RockPro64 seems way more serious: ERROR: [ 1.232672] basic hdkf test(hmac(sha256)): failed to allocate transform:= -2 [ 14.172991] alg: ahash: rk-sha1 export() overran state buffer on test ve= ctor 0, cfg=3D"import/export" [ 14.202291] alg: ahash: rk-sha256 export() overran state buffer on test = vector 0, cfg=3D"import/export" [ 14.230887] alg: ahash: rk-md5 export() overran state buffer on test vec= tor 0, cfg=3D"import/export" WARNING: [ 1.234017] alg: full crypto tests enabled.
