      IB/addr: Fix setting source address in addr6_resolve() · 79e25959
      Roland Dreier authored
      Commit eea40b8f ("infiniband: call ipv6 route lookup via the stub
      interface") introduced a regression in address resolution when connecting
      to IPv6 destination addresses.  The old code called ip6_route_output(),
      while the new code calls ipv6_stub->ipv6_dst_lookup().  The two are almost
      the same, except that ipv6_dst_lookup() also calls ip6_route_get_saddr()
      if the source address is in6addr_any.
      
      This means that the test of ipv6_addr_any(&fl6.saddr) now never succeeds,
      and so we never copy the source address out.  This ends up causing
      rdma_resolve_addr() to fail, because without a resolved source address,
      cma_acquire_dev() will fail to find an RDMA device to use.  For me, this
      causes connecting to an NVMe over Fabrics target via RoCE / IPv6 to fail.
      
      Fix this by copying out fl6.saddr if ipv6_addr_any() is true for the original
      source address passed into addr6_resolve().  We can drop our call to
      ipv6_dev_get_saddr() because ipv6_dst_lookup() already does that work.
