From 6363d81b78c00d98f6d92b04acf65b4a18013690 Mon Sep 17 00:00:00 2001 From: Robert Elliott Date: Sun, 14 Aug 2022 23:29:15 -0500 Subject: crypto: tcrypt - remove mode=1000 The lists of algothms checked for existence by modprobe tcrypt mode=1000 generates three bogus errors: modprobe tcrypt mode=1000 console log: tcrypt: alg rot13 not found tcrypt: alg cts not found tcrypt: alg arc4 not found rot13 is not an algorithm in the crypto API or tested. cts is a wrapper, not a base algorithm. arc4 is named ecb(arc4), not arc4. Also, the list is missing numerous algorithms that are tested by other test modes: blake2b-512 blake2s-256 crct10dif xxhash64 ghash cast5 sm4 ansi_prng Several of the algorithms are only available if CONFIG_CRYPTO_USER_API_ENABLE_OBSOLETE is enabled: arc4 khazad seed tea, xtea, xeta Rather that fix that list, remove test mode=1000 entirely. It seems to have limited utility, and a web search shows no discussion of anybody using it.
