A vma with vm_pgoff large enough to overflow a loff_t type when
converted to a byte offset can be passed via the remap_file_pages
system call. The hugetlbfs mmap routine uses the byte offset to
calculate reservations and file size.
A sequence such as:
mmap(0x20a0, 0x60, 0, 0x66033, -1,
A vma with vm_pgoff large enough to overflow a loff_t type when
converted to a byte offset can be passed via the remap_file_pages
system call. The hugetlbfs mmap routine uses the byte offset to
calculate reservations and file size.
A sequence such as:
mmap(0x20a0, 0x60, 0, 0x66033, -1,
