Subject: [PATCH 28/73] ipv4: Fix wrong order of ip_rt_get_source() and update
iph->daddr.
[ Upstream commit 5dc7883f2a7c25f8df40d7479687153558cd531b ]
This patch fix a bug which introduced by commit ac8a4810 (ipv4: Save
nexthop address of LSRR/SSRR option to IPCB.).In that patch, we saved
the nexthop of SRR in ip_option->nexthop and update iph->daddr until
we get to ip_forward_options(), but we need to update it before
ip_rt_get_source(), otherwise we may get a wrong src.
