| H A D | if_dl.h | diff 96184 Tue May 07 20:14:06 MDT 2002 kbyanc Move ISO88025 source routing information into sockaddr_dl's sdl_data field. This returns the sdl_data field to a variable-length field. More importantly, this prevents a easily-reproduceable data-corruption bug when the interface name plus the hardware address exceed the sdl_data field's original 12 byte limit. However, token-ring interfaces may still overflow the new sdl_data field's 46 byte limit if the interface name exceeds 6 characters (since 6 characters for interface name plus 6 for hardware address plus 34 for source routing = the size of sdl_data). Further refinements could overcome this limitation but would break binary compatibility; this commit only addresses fixing the bug for commonly-occuring cases without breaking binary compatibility with the intention that the functionality can be MFC'ed to -stable. See message ID's (both send to -arch): 20020421013332.F87395-100000@gateway.posi.net 20020430181359.G11009-300000@gateway.posi.net for a more thorough description of the bug addressed and how to reproduce it.
