Date: Tue Apr 7 18:58:45 2020 +0300 # # crypto: caam - fix the address of the last entry of S/G # # For skcipher algorithms, the input, output HW S/G tables # look like this: [IV, src][dst, IV] # Now, we can have 2 conditions here: # - there is no IV; # - src and dst are equal (in-place encryption) and scattered # and the error is an "off-by-one" in the HW S/G table. # # This issue was seen with KASAN: # BUG: KASAN: slab-out-of-bounds in skcipher_edesc_alloc+0x95c/0x1018 #
