Which\nsometimes leads to mistakes. If len passed to kmalloc is smaller that len\npassed to memcpy, it\u0027s straight overwrite-beyond-end. If len passed to\nmemcpy is smaller than len passed to kmalloc, it\u0027s either a) legit\nbehaviour ;-), or b) cloned buffer will contain garbage in second half.\n\nSlight trolling of commit lists shows several duplications bugs\ndone exactly because of diverged lenghts:\n\n\tLinux:\n\t\t[CRYPTO]: Fix memcpy/memset args.\n\t\t[PATCH] memcpy/memset fixes\n\tOpenBSD:\n\t\tkerberosV/src/lib/asn1: der_copy.c:1.4\n\nIf programmer is given only one place to play with lengths, I believe, such\nmistakes could be avoided.\n\nWith kmemdup, the snippet above will be rewritten as:\n\n\tdst \u003d kmemdup(src, len, GFP_KERNEL);\n\tif (!dst)\n\t\treturn -ENOMEM;\n\nThis also leads to smaller code (kzalloc effect).
