I've recently upgraded some of my machines to linux kernel 18.104.22.168.atmel.1 (using buildroot 2.3.0) and have noticed a bit of an issue with udhcpc.
First of all, I had to edit the /usr/share/default.script because this section:
if [ -n "$router" ] ; then echo "deleting routers" while route del default gw 0.0.0.0 dev $interface ; do : done for i in $router ; do route add default gw $i dev $interface done fi
would just cause everything to halt after it prints "deleting routers". It wouldn't boot any further. So, I commented this section out and everything seemed to work ok after that.
However, I've just noticed the issue that the avr32 boots properly and gets the DNS stuff all setup as I had it going before, but the udhcpc process just quits after an indeterminate amount of time. This means the name doesn't resolve anymore (even though it still has the IP Address).
I'm piping the output of udhcpc to a file to hope to catch any errors it might print before quitting, any other recommendations for things to check? Might the two issues I had with the deleting routers and this be related? The busybox version is v1.13.1..
