sctp: integer overflow in sctp_auth_create_key() The previous commit 30c2235c is incomplete and cannot prevent integer overflows. For example, when key_len is 0x80000000 (INT_MAX + 1), the left-hand side of the check, (INT_MAX - key_len), which is unsigned, becomes 0xffffffff (UINT_MAX) and bypasses the check.
