Rasmus Villemoes <ravi@prevas.dk> says: There are quite a few places where we allocate X+1 bytes, initialize the first X bytes via memcpy() and then set the last byte to 0. The kernel has a helper for that, kmemdup_nul(). Introduce a similar one, and start making use of it in a few places. Also the existing memdup() helper can be put to more use. There are lots more places one could modify. But for code shared with host tools, one would need to do some refactoring, putting memdup() and memdup_nul() in their own str-util.c TU which could then also be included in the tools build.
