There was recently a patch to the random driver to replace memset() because, according to the submitter, gcc sometimes optimises memset() away which might leave data unnecessarily exposed. The solution suggested was a function called memzero_explicit(). There was a fair bit of discussion and the patch was accepted.
In the crypto directory of the kernel source I have: $ grep memset *.c | wc -l 133 $ I strongly suspect some of these should be fixed. -- To unsubscribe from this list: send the line "unsubscribe linux-crypto" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
