Quoting from https://maskray.me/blog/2023-04-12-elf-hash-function: The System V Application Binary Interface (generic ABI) specifies the ELF object file format. When producing an output executable or shared object needing a dynamic symbol table (.dynsym), a linker generates a .hash section with type SHT_HASH to hold a symbol hash table. A DT_HASH tag is produced to hold the address of .hash. The function is supposed to return a value no larger than 0x0fffffff. Unfortunately, there is a bug. When unsigned long consists of more than 32 bits, the return value may be larger than UINT32_MAX. For instance, elf_hash((const unsigned char *)"\xff\x0f\x0f\x0f\x0f\x0f\x12") returns 0x100000002, which is clearly unintended, as the function should behave the same way regardless of whether long represents a 32-bit integer or a 64-bit integer.
