| |
Dearest Kernel Hackers,
We discovered the following bug when bringing up a new Linux router today.
We're running a stock Debian potato dist with Traffic Shaper installed to choke off outbound traffic, using shaper-0.15 (latest). A minor config-file error in our /etc/init.d/network script produced a nasty kernel panic (kernel: 2.2.9 -- latest stable).
Here's how we produed the kernel panic: (stuff from our network script)
1. ifconfig eth0 [ipaddr0] netmak [mask0] broadcast [bcast0] 2. route add default gw [gw] metric 1 3. shapecfg attach shaper0 eth1 4. shapecfg speed shaper0 [speed] 5. ifconfig shaper0 [ipaddr1] netmak [mask1] broadcast [bcast1] 6. route add -net [network0] netmask [mask0] dev shaper0
Everything works fine so far, but as soon as we typed "route" or tried to send packets over the interface, it panicked, coughed, bled and died.
Replacing step #6 with:
if [ -e /proc/net/ip_input ]; then route add -net [network1] netmask [mask1] dev shaper0 fi
avoided the problem. While it was a stupid config error on our part, it should not be bringing down the stable kernel (which is supposed to be bulletproof... :)
