The 'old_fd' parameter used for atomic replacement of XDP programs is supposed to be an FD, but was left as a u32 from an earlier iteration of the patch that added it. It was converted to an int when read, so things worked correctly even with negative values, but better change the definition to correctly reflect the intention. Fixes: bd5ca3ef ("libbpf: Add function to set link XDP fd while specifying old program") Reported-by:
