Subject: PROBLEM: encryption test failures since "crypto: mxs-dcp - Use sg_mapping_iter to copy data"
Date: Thu, 27 Jan 2022 18:23:13 +0100 [thread overview]
Message-ID: <2126453.Icojqenx9y@localhost.localdomain> (raw)
SoC: i.MX6ULL
After upgrading from v5.10.65-rt53 to v5.10.73-rt54 I get two additional messages on boot:
...
[ 3.786333] alg: skcipher: ecb-aes-dcp encryption test failed (wrong result) on test vector 0, cfg="two even aligned splits"
[ 3.789020] alg: skcipher: cbc-aes-dcp encryption test failed (wrong result) on test vector 0, cfg="two even aligned splits"
[ 3.793741] mxs-dcp 2280000.crypto: mxs_dcp: initialized
..
After reverting the commit
2e6d793e1bf0 ("crypto: mxs-dcp - Use sg_mapping_iter to copy data")
the error messages above disappear again.
regards
Christian
