David Miller 89087c456f bpf: Fix values type used in test_maps ... Maps of per-cpu type have their value element size adjusted to 8 if it is specified smaller during various map operations. This makes test_maps as a 32-bit binary fail, in fact the kernel writes past the end of the value's array on the user's stack. To be quite honest, I think the kernel should reject creation of a per-cpu map that doesn't have a value size of at least 8 if that's what the kernel is going to silently adjust to later. If the user passed something smaller, it is a sizeof() calcualtion based upon the type they will actually use (just like in this testcase code) in later calls to the map operations.
