Here's an interesting way to blow up your box, providing IPv6 is a module:
ifconfig eth0 up 192.168.1.1 ifconfig eth0:0 up 192.168.1.2 modprobe ipv6 ifconfig eth0 down ifconfig eth0 up 192.168.1.1 ifconfig eth0:0 up 192.168.1.2 *kaboom*
Here, you'll either get a non-fatal Oops complaining about a null-pointer dereference, or a continuous Oops scrolling up your screen at warp 43 (or should that be warp 6? :), with the box locked totally dead.
In 2.1.12, I had both ip_alias and ipv6 as modules, in 2.1.13 I moved ipv6 into my kernel. In the first case, my bootup scripts were able to add the IP aliases without harm, because IPv6 wasn't yet loaded. If I then loaded ipv6, *kaboom*. In the second case, ip_alias refused to load, and so my bootup scripts did nothing (thankfully, or I would've had a bit of a problem on my hands...)
Anyone wanna take a look at this one? :)
