All these panics were fixed just a couple of lines above the panicing code. Take a more general approach: sanity check sockaddrs supplied with SIOCAIFADDR and SIOCSIF*ADDR at the beggining of the function and drop all checks below. One check is now disabled due to strange code in ifconfig(8) that I've removed recently. I'm going to enable it with next __FreeBSD_version bump. Historically in_ifinit() was able to recover from an error and restore old address. Nowadays this feature isn't working for all error cases, but for some of them. I suppose no software relies on this behavior, so I'd like to remove it, since this simplifies code a lot. Also, move if_scrub() earlier in the in_ifinit(). It is more correct to wipe routes before removing address from local address list, and interface address list. Silence from: bz, brooks, andre, rwatson, 3 weeks |
