ip_tunnel(ipv4): fix tunnels with "local any remote $remote_ip" Ipv4 tunnels created with "local any remote $ip" didn't work properly since 7d442fab0 (ipv4: Cache dst in tunnels). 99% of packets sent via those tunnels had src addr = 0.0.0.0. That was because only dst_entry was cached, although fl4.saddr has to be cached too. Every time ip_tunnel_xmit used cached dst_entry (tunnel_rtable_get returned non-NULL), fl4.saddr was initialized with tnl_params->saddr (= 0 in our case), and wasn't changed until iptunnel_xmit(). This patch adds saddr to ip_tunnel->dst_cache, fixing this issue. Reported-by: Sergey Popov <pinkbyte@gentoo.org> Signed-off-by: Dmitry Popov <ixaphire@qrator.net> Signed-off-by: David S.
