The following path will cause array out of bound.
memblock_add_region() will always set nid in memblock.reserved to MAX_NUMNODES.
In numa_register_memblks(), after we set all nid to correct valus in memblock.reserved,
we called setup_node_data(), and used memblock_alloc_nid() to allocate memory, with
nid set to MAX_NUMNODES.
The nodemask_t type can be seen as a bit array. And the index is 0 ~ MAX_NUMNODES-1.
After that, when we call node_set() in numa_clear_kernel_node_hotplug(), the nodemask_t
got an index of value MAX_NUMNODES, which is out of [0 ~ MAX_NUMNODES-1].
See below:
numa_init()
|---> numa_register_memblks()
| |---> memblock_set_node(memory) set correct nid in memblock.memory
| |---> memblock_set_node(reserved) set correct nid in memblock.reserved
| |......
| |---> setup_node_data()
| |---> memblock_alloc_nid() here, nid is set to MAX_NUMNODES (1024)
|......
|---> numa_clear_kernel_node_hotplug()
|---> node_set() here, we have an index 1024, and overflowed
This patch moves nid setting to numa_clear_kernel_node_hotplug() to fix this problem.
