Yuchung Cheng deed7be78f tcp: record most recent RTT in RACK loss detection
Record the most recent RTT in RACK. It is often identical to the
"ca_rtt_us" values in tcp_clean_rtx_queue. But when the packet has
been retransmitted, RACK choses to believe the ACK is for the
(latest) retransmitted packet if the RTT is over minimum RTT.

This requires passing the arrival time of the most recent ACK to
RACK routines. The timestamp is now recorded in the "ack_time"
in tcp_sacktag_state during the ACK processing.

This patch does not change the RACK algorithm itself. It only adds
the RTT variable to prepare the next main patch.

Nikolay Aleksandrov 8fb472c09b ipmr: improve hash scalability
Recently we started using ipmr with thousands of entries and easily hit
soft lockups on smaller devices. The reason is that the hash function
uses the high order bits from the src and dst, but those don't change in
many common cases, also the hash table  is only 64 elements so with
thousands it doesn't scale at all.
This patch migrates the hash table to rhashtable, and in particular the
rhl interface which allows for duplicate elements to be chained because
of the MFC_PROXY support (*,G; *,*,oif cases) which allows for multiple
duplicate entries to be added with different interfaces (IMO wrong, but
it's been in for a long time).

And here are some results from tests I've run in a VM:
 mr_table size (default, allocated for all namespaces):
  Before                    After
   49304 bytes               2400 bytes

 Add 65000 routes (the diff is much larger on smaller devices):
  Before                    After
   1m42s                     58s

 Forwarding 256 byte packets with 65000 routes (test done in a VM):
  Before                    After
   3 Mbps / ~1465 pps        122 Mbps / ~59000 pps

As a bonus we no longer see the soft lockups on smaller devices which
showed up even with 2000 entries before.

Ursula Braun e48b9eaaa2 s390/qeth: fix retrieval of vipa and proxy-arp addresses
qeth devices in layer3 mode need a separate handling of vipa and proxy-arp
addresses. vipa and proxy-arp addresses processed by qeth can be read from
userspace. Introduced with commit 5f78e29cee ("qeth: optimize IP handling
in rx_mode callback") the retrieval of vipa and proxy-arp addresses is
broken, if more than one vipa or proxy-arp address are set.

The qeth code used local variable "int i" for 2 different purposes. This
patch now spends 2 separate local variables of type "int".
While touching these functions hash_for_each_safe() is converted to
hash_for_each(), since there is no removal of hash entries.

Thomas Richter f9d8e6dc0f s390/qeth: test RX/TX checksum offload reply
Turning on receive and/or transmit checksum offload support
on the OSA card requires 2 commands:
1. start command which replies with available features
2. enable command to turn on selected features.

The current version does not check the reply of the start
command and simply uses the returned value to enable
offload features. When the start command returns zero, this
leads to a situation where no checksum offload
is turned on by the hardware. Even worse no error
indication is returned. The Linux kernel assumes
the OSA card performs RX/TX checksum offload, but the hardware
does not perform any checksum verification at all.

This patch checks the return of the start and enable
command responses from the hardware and turns off
checksum offloading if the commands fails or does not
respond with the correct bit setting.

instruction that is based on the user ctx structure into a kernel
representation for the ctx. As we'd like to allow access size beyond
just BPF_W, we'd need also insn->code for that in order to decode the
original access size. Given that, lets just pass insn directly to the
convert_ctx_access() callback and work on that to not clutter the
callback with even more arguments we need to pass when everything is
already contained in insn. So lets go through that once, no functional
change.

When creating an SMC connection, there is a CLC (connection layer control)
handshake to prepare for RDMA traffic. The corresponding code is part of
commit 0cfdd8f92c ("smc: connection and link group creation").
Mac addresses to be exchanged in the handshake are copied with a wrong
length of 12 instead of 6 bytes. Following code overwrites the wrongly
copied code, but nevertheless the correct length should already be used for
the preceding mac address copying. Use ETH_ALEN for the memcpy length with

Linus Torvalds cff3b2c4b3 Merge git://git.kernel.org/pub/scm/linux/kernel/git/davem/net
Pull networking fixes from David Miller:

 1) Fix rtlwifi crash, from Larry Finger.

 2) Memory disclosure in appletalk ipddp routing code, from Vlad
    Tsyrklevich.

 3) r8152 can erroneously split an RX packet into multiple URBs if the
    Rx FIFO is not empty when we suspend. Fix this by waiting for the
    FIFO to empty before suspending. From Hayes Wang.

 4) Two GRO fixes (enter slow path when not enough SKB tail room exists,
    disable frag0 optimizations when there are IPV6 extension headers)
    from Eric Dumazet and Herbert Xu.

 5) A series of mlx5e bug fixes (do source udp port offloading for
    tunnels properly, Ip fragment matching fixes, handling firmware
    errors properly when installing TC rules, etc.) from Saeed Mahameed,
    Or Gerlitz, Roi Dayan, Hadar Hen Zion, Gil Rockah, and Daniel
    Jurgens.

 6) Two VRF fixes from David Ahern (don't skip multipath selection for

Keerthy 380043b9de net: netcp: correct netcp_get_stats function signature
Commit: bc1f44709c - net: make ndo_get_stats64 a void function
and
Commit: 6a8162e99e - net: netcp: store network statistics in 64 bits.

The commit 6a8162e99e adds ndo_get_stats64 function as per old
signature which causes compilation error:

drivers/net/ethernet/ti/netcp_core.c:1951:28: error:
initialization from incompatible pointer type
  .ndo_get_stats64        = netcp_get_stats,

Hence correct netcp_get_stats function signature as per
the latest definition.
