The CRYPTO_TFM_RES_WEAK_KEY flag was apparently meant as a way to make the ->setkey() functions provide more information about errors. However, no one actually checks for this flag, which makes it pointless. There are also no tests that verify that all algorithms actually set (or don't set) it correctly. This is also the last remaining CRYPTO_TFM_RES_* flag, which means that it's the only thing still needing all the boilerplate code which propagates these flags around from child => parent tfms. And if someone ever needs to distinguish this error in the future (which is somewhat unlikely, as it's been unneeded for a long time), it would be much better to just define a new return value like -EKEYREJECTED. That would be much simpler, less error-prone, and easier to test. So just remove this flag. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> |
