ipv4: sendto/hdrincl: don't use destination address found in header
[ Upstream commit c27c9322d015dc1d9dfdf31724fca71c0476c4d1 ]
ipv4: raw_sendmsg: don't use header's destination address
A sendto() regression was bisected and found to start with commit
f8126f1d5136be1 (ipv4: Adjust semantics of rt->rt_gateway.)
The problem is that it tries to ARP-lookup the constructed packet's
destination address rather than the explicitly provided address.
Fix this using FLOWI_FLAG_KNOWN_NH so that given nexthop is used.
cf. commit 2ad5b9e4bd314fc685086b99e90e5de3bc59e26b
