I see no point in keeping them since nothing else appears to implement or use "hmac(crc32)", which isn't an algorithm that makes sense anyway because HMAC is meant to be used with a cryptographically secure hash function, which CRC's are not. Thus, remove the unneeded test vectors. Signed-off-by: Eric Biggers <ebiggers@google.com> Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au>

crypto: tcrypt - Remove VLA usage 2018-05-05T06:52:53+00:00 Kees Cook keescook@chromium.org 2018-04-27T02:57:28+00:00 4e234eed58518a8df69a5d14d303b18ed9559832 In the quest to remove all stack VLA usage from the kernel[1], this allocates the return code buffers before starting jiffie timers, rather than using stack space for the array. Additionally cleans up some exit paths and make sure that the num_mb module_param() is used only once per execution to avoid possible races in the value changing.
