Description Tyler Montbriand 2007-10-16 16:33:11 UTC

dhcpcd 3.x's new zeroconf feature causes failovers to not work unless zeroconf is specifically disabled with the -L flag.

When dhcpcd fails to get a response from the DHCP server, it does not exit with an error code, it sets the interface to a random address in the 169.x.y.z range and returns success.

Reproducible: Always

Steps to Reproduce:
1. In /etc/conf.d/net :
config_eth0=( "dhcp" )
fallback_wan=( "192.168.0.2/24" )
fallback_route_wan=( "default via 192.168.0.1" )

2. Disconnect network cable from eth0

3. /etc/init.d/net.eth0 restart
Actual Results:  
dhcpcd does not return error, preventing the failover from working.  Instead it sets the interface to a random address in the 169.x.y.z range.

When the option:

dhcpcd_eth0="-L"

is present in /etc/conf.d/net, failovers behave as they did with dhcpcd 2.x.

Expected Results:  
I expected the failovers to work as they did with dhcpcd 2.x

What's the critical issue here? Misconfiguration on your side? This is an intended behaviour.
