Ryan Ware d185fa4570 EVM: Use crypto_memneq() for digest comparisons ... [ Upstream commit 613317bd21 ] This patch fixes vulnerability CVE-2016-2085. The problem exists because the vm_verify_hmac() function includes a use of memcmp(). Unfortunately, this allows timing side channel attacks; specifically a MAC forgery complexity drop from 2^128 to 2^12. This patch changes the memcmp() to the cryptographically safe crypto_memneq().
