      net/ipv6: Simplify route replace and appending into multipath route · f34436a4
      David Ahern authored 
      Bring consistency to ipv6 route replace and append semantics.

Remove rt6_qualify_for_ecmp which is just guess work. It fails in 2 cases:
1. can not replace a route with a reject route. Existing code appends
   a new route instead of replacing the existing one.

2. can not have a multipath route where a leg uses a dev only nexthop

Existing use cases affected by this change:
1. adding a route with existing prefix and metric using NLM_F_CREATE
   without NLM_F_APPEND or NLM_F_EXCL (ie., what iproute2 calls
   'prepend'). Existing code auto-determines that the new nexthop can
   be appended to an existing route to create a multipath route. This
   change breaks that by requiring the APPEND flag for the new route
   to be added to an existing one. Instead the prepend just adds another
   route entry.

2. route replace. Existing code replaces first matching multipath route
   if new route is multipath capable and fallback to first matching
   non-ECMP route (reject or dev only route) in case one isn't available.
   New behavior replaces first matching route. (Thanks to Ido for spotting
   this one)

Note: Newer iproute2 is needed to display multipath routes with a dev-only
      nexthop. This is due to a bug in iproute2 and parsing nexthops.

====================
TI Ethernet driver warnings fixes

This patch series attempts to fix properly the warnings observed with turning
on COMPILE_TEST and TI Ethernet drivers on 64-bit hosts.

Since I don't have any of this hardware, please review carefully for possible
breakage!

      ti: ethernet: davinci: Fix cast to int warnings · c79c3850
      Florian Fainelli authored 
      Now that we can compile test this driver on 64-bit hosts, we get some
warnings about how a pointer/address is written/read to/from a register
(sw_token). Fix this by doing the appropriate conversions, we cannot
possibly have the driver work on 64-bit hosts the way the tokens are
managed though, since the registers being written to a 32-bit only.

      S390 bpf_jit.S is removed in net-next and had changes in 'net',
since that code isn't used any more take the removal.

TLS data structures split the TX and RX components in 'net-next',
put the new struct members from the bug fix in 'net' into the RX
part.

The 'net-next' tree had some reworking of how the ERSPAN code works in
the GRE tunneling code, overlapping with a one-line headroom
calculation fix in 'net'.

Overlapping changes in __sock_map_ctx_update_elem(), keep the bits
that read the prog members via READ_ONCE() into local variables
before using them.

The function vmcore_add_device_dump() references

      cxgb4: copy the length of cpl_tx_pkt_core to fw_wr · a6076fcd
      Ganesh Goudar authored 
      immdlen field of FW_ETH_TX_PKT_WR is filled in a wrong way,
we must copy the length of all the cpls encapsulated in fw
work request. In the xmit path we missed adding the length
of CPL_TX_PKT_CORE but we added the length of WR_HDR and it
worked because WR_HDR and CPL_TX_PKT_CORE are of same length.
Add the length of cpl_tx_pkt_core not WR_HDR's. This also
fixes the lso cpl errors for udp tunnels
