the link level name for the interface (ifp->if_sadl) is allocated before ifp->if_addrlen is initialized, which could lead to allocating too little space for the link level address. Do this by splitting allocation of the link level name out of if_attach() and into if_alloc_sadl(), which is normally called by functions like ether_ifattach(). Network interfaces which don't have a link-specific attach routine must call if_alloc_sadl() themselves (example: gif). Link level names are freed by if_free_sadl(), which can be called from e.g. ether_ifdetach(). Drivers never need call if_free_sadl() themselves as if_detach() will do it if it is not already done. While here, add the ability to pass an AF_LINK address to SIOCSIFADDR in ether_ioctl() (this is what caused me to notice the problem that the above fixes). |
