Hi, I am using a Banana Pi BPI-R3 router board, which has a MediaTek MT7986 SoC, with Linux and I have noticed a large number of error messages and stack traces in my kernel boot log related to the crypto-safexcel module. The errors all related to a large number of failed self-tests for both hashing and encryption, thus I believe this device is not working correctly at all. I have been using the current Debian unstable distribution with a variety of kernel builds. I have seen the errors with both Debian and "vanilla" builds of v6.8.12, v6.9.7 and v6.10.0-rc6. To reproduce, simply boot Linux on the BPI-R3 using the compiled DTS file arch/arm64/boot/dts/mediatek/mt7986a-bananapi-bpi-r3.dts with the crypto-safexcel module enabled via the CONFIG_CRYPTO_DEV_SAFEXCEL option. Any help fixing these errors would be appreciated. The relevant boot log messages: crypto-safexcel 10320000.crypto: EIP97:230(0,1,4,4)-HIA:270(0,5,5),PE:150/433(alg:7fcdfc00)/0/0/0 alg: ahash: safexcel-sha384 test failed (wrong result) on test vector 1, cfg="init+update+final aligned buffer" alg: self-tests for sha384 using safexcel-sha384 failed (rc=-22) alg: ahash: safexcel-sha512 test failed (wrong result) on test vector 1, cfg="init+update+final aligned buffer" alg: self-tests for sha512 using safexcel-sha512 failed (rc=-22) alg: ahash: safexcel-hmac-sha384 setkey failed on test vector 0; expected_error=0, actual_error=-80, flags=0x1 alg: self-tests for hmac(sha384) using safexcel-hmac-sha384 failed (rc=-80) alg: ahash: safexcel-hmac-sha512 setkey failed on test vector 0; expected_error=0, actual_error=-80, flags=0x1 alg: self-tests for hmac(sha512) using safexcel-hmac-sha512 failed (rc=-80) alg: aead: safexcel-authenc-hmac-sha512-cbc-aes encryption test failed (wrong result) on test vector 0, cfg="in-place (one sglist)" alg: self-tests for authenc(hmac(sha512),cbc(aes)) using safexcel-authenc-hmac-sha512-cbc-aes failed (rc=-22) alg: aead: safexcel-authenc-hmac-sha512-cbc-des3_ede encryption test failed (wrong result) on test vector 0, cfg="in-place (one sglist)" alg: self-tests for authenc(hmac(sha512),cbc(des3_ede)) using safexcel-authenc-hmac-sha512-cbc-des3_ede failed (rc=-22 alg: aead: safexcel-authenc-hmac-sha384-cbc-des3_ede encryption test failed (wrong result) on test vector 0, cfg="in-place (one sglist)" alg: self-tests for authenc(hmac(sha384),cbc(des3_ede)) using safexcel-authenc-hmac-sha384-cbc-des3_ede failed (rc=-22) alg: aead: safexcel-authenc-hmac-sha512-cbc-des encryption test failed (wrong result) on test vector 0, cfg="in-place (one sglist)" alg: self-tests for authenc(hmac(sha512),cbc(des)) using safexcel-authenc-hmac-sha512-cbc-des failed (rc=-22) alg: aead: safexcel-authenc-hmac-sha384-cbc-des encryption test failed (wrong result) on test vector 0, cfg="in-place (one sglist)" alg: self-tests for authenc(hmac(sha384),cbc(des)) using safexcel-authenc-hmac-sha384-cbc-des failed (rc=-22) Thanks, Leith Bade
