Hello,

my box is configured to use wlan via wpa_supplicant using dhcp. On my dhcp-server there is an entry for one static route (host route via gateway).
Problem: The netifrc scripts on client side do not add this given static route as a host-route; the routing table shows a route without gateway address.
Btw., dhcpd gives the right data when asking my dhcp-server.

This problem occures since an update this summer, I don't know anymore which packages are new, think about dhcpd or wpa_supplicant.

Here's the response from dhcpd on my client when starting interface wlan0:

Nov 15 00:52:04 aphrodite dhcpcd[6076]: wlan0: adding route to 192.168.178.0/24
Nov 15 00:52:04 aphrodite dhcpcd[6076]: wlan0: adding host route to 10.0.0.1 via 192.168.178.6 --> this is the special host route, response from dhcp-server ok
Nov 15 00:52:04 aphrodite dhcpcd[6076]: wlan0: adding default route via 192.168.178.1
Nov 15 00:52:04 aphrodite dhcpcd[6076]: wlan0: removing route to 192.168.178.0/24


As you can see, dhcpd tells the right host route via the right interface

But the resulting kernel routing table looks like this:

Quote:	

ip route list
default via 192.168.178.1 dev wlan0 metric 302
10.0.0.1 dev wlan0 metric 302 ---> this line is wrong, I can't ping 10.0.0.1, gateway missing
127.0.0.0/8 dev lo scope host
127.0.0.0/8 via 127.0.0.1 dev lo
192.168.178.0/24 dev wlan0 proto kernel scope link src 192.168.178.122 metric 302


If I manually run this:

Quote:	

ip route add 10.0.0.1 via 192.168.178.6


it works and I can ping the 10.0.0.1!!!
Routing table like this:
Quote:	

ip route list
default via 192.168.178.1 dev wlan0 metric 302
10.0.0.1 dev wlan0 metric 302
10.0.0.1 via 192.168.178.6 dev wlan0 --> here is the difference!
127.0.0.0/8 dev lo scope host
127.0.0.0/8 via 127.0.0.1 dev lo
192.168.178.0/24 dev wlan0 proto kernel scope link src 192.168.178.122 metric 302


Can someone tell me, why the host route is not added correctly?

x86 stabilization team doesn't belong here.

@netifrc, could you handle this?

Please retest on netifrc-9999, and if the problem persists, post your /etc/conf.d/net (with passwords/keys redacted as needed).
