[OpenWrt-Devel] dnsmasq stops receiving packets after network restart

Hi Kristian,

does the same happen without "bind-dynamic" ? My hunch is that dnsmasq
fails to "resubscribe" to the socket after the ifindex of br-lan changed
due to the network restart (which will destroy and recreate br-lan).

Maybe netlink congestion or something related to privilege dropping? Can
you manage to capture an strace log of the running dnsmasq instance
while the network is getting restarted?
