      net: amd-xgbe: Add hardware dependency · 74a78b15
      Jean Delvare authored 
      The amd-xgbe driver currently only works with the Seattle SoC, which
is ARM64 architecture, so there is no point in building this driver on
other architectures except for build testing purpose. The dependency
list can be updated later if the driver ever supports other
architectures.

      net_sched: fix a use-after-free in tc_ctl_tfilter() · d7443185
      WANG Cong authored 
      When tcf_destroy() returns true, tp could be already destroyed,
we should not use tp->next after that.

For long term, we probably should move tp list to list_head.

      net: macb: Handle the RXUBR interrupt on all devices · bfbb92c4
      Nathan Sullivan authored 
      The same hardware issue the at91 must work around applies to at least the
Zynq ethernet, and possibly more devices.  The driver also needs to handle
the RXUBR interrupt since it turns it on with MACB_RX_INT_FLAGS anyway.

net/rds: RDS-TCP robustness fixes

This patch-set contains bug fixes for state-recovery at the RDS
layer when the underlying transport is TCP and the TCP state at one
of the endpoints is reset

V2 changes: DaveM comments to reduce memory footprint, follow
            NFS/RPC model where possible. Added test-case #3

Without the changes in this set, when one of the endpoints is reset,
the existing code does not correctly clean up RDS socket state for stale
connections, resulting in some unstable, timing-dependant behavior on
the wire, including an infinite exchange of 3WHs back-and-forth, and a
resulting potential to never converge RDS state.

Test cases used to verify the changes in this set are:

1. Start rds client/server applications on two participating nodes,
   node1 and node2. After at least one packet has been sent (to establish
   the TCP connection), restart the rds_tcp module on the client, and
   now resend packets. Tcpdump should show server sending a FIN for the
   "old" client port, and clean connection establishment/exchange for
   the new client port.

2. At the end of step 1, restart rds srever on node2, and start client on
   node1, make sure using tcpdump, 'netstat -an|grep 16385' that
   packets flow correctly.

3. start RDS client/server application on two participating nodes, and
   repeat steps 1 and 2, but this time, simulate node failure by doing
   "ifconfig <intf> down", so no FIN is sent.

      net/rds: RDS-TCP: only initiate reconnect attempt on outgoing TCP socket. · c82ac7e6
      Sowmini Varadhan authored 
      When the peer of an RDS-TCP connection restarts, a reconnect
attempt should only be made from the active side  of the TCP
connection, i.e. the side that has a transient TCP port
number. Do not add the passive side of the TCP connection
to the c_hash_node and thus avoid triggering rds_queue_reconnect()
for passive rds connections.

      net/rds: RDS-TCP: Always create a new rds_sock for an incoming connection. · f711a6ae
      Sowmini Varadhan authored 
      When running RDS over TCP, the active (client) side connects to the
listening ("passive") side at the RDS_TCP_PORT.  After the connection
is established, if the client side reboots (potentially without even
sending a FIN) the server still has a TCP socket in the esablished
state.  If the server-side now gets a new SYN comes from the client
with a different client port, TCP will create a new socket-pair, but
the RDS layer will incorrectly pull up the old rds_connection (which
is still associated with the stale t_sock and RDS socket state).

This patch corrects this behavior by having rds_tcp_accept_one()
always create a new connection for an incoming TCP SYN.
The rds and tcp state associated with the old socket-pair is cleaned
up via the rds_tcp_state_change() callback which would typically be
invoked in most cases when the client-TCP sends a FIN on TCP restart,
triggering a transition to CLOSE_WAIT state. In the rarer event of client
death without a FIN, TCP_KEEPALIVE probes on the socket will detect
the stale socket, and the TCP transition to CLOSE state will trigger
the RDS state cleanup.

      ipv6: Fixed source specific default route handling. · e16e888b
      Markus Stenberg authored 
      If there are only IPv6 source specific default routes present, the
host gets -ENETUNREACH on e.g. connect() because ip6_dst_lookup_tail
calls ip6_route_output first, and given source address any, it fails,
and ip6_route_get_saddr is never called.

The change is to use the ip6_route_get_saddr, even if the initial
ip6_route_output fails, and then doing ip6_route_output _again_ after
we have appropriate source address available.

Note that this is '99% fix' to the problem; a correct fix would be to
do route lookups only within addrconf.c when picking a source address,
and never call ip6_route_output before source address has been
populated.
