XGMII is a 32-bit bus plus two clock signals per direction.  XAUI is
four serial lanes per direction.  The 88e6190 supports XAUI but not
XGMII as it doesn't have enough pins.  The same is true of 88e6176.

Match on PHY_INTERFACE_MODE_XAUI for the XAUI port type, but keep
accepting XGMII for backwards compatibility.

The function call path is:
rr_close (acquire the spinlock)

Netfilter fixes for net

The follow patchset contains Netfilter fixes for your net tree,
they are:

1) Fix compilation warning in x_tables with clang due to useless
   redundant reassignment, from Colin Ian King.

2) Add bugtrap to net_exit to catch uninitialized lists, patch
   from Vasily Averin.

3) Fix out of bounds memory reads in H323 conntrack helper, this
   comes with an initial patch to remove replace the obscure
   CHECK_BOUND macro as a dependency. From Eric Sesterhenn.

4) Reduce retransmission timeout when window is 0 in TCP conntrack,
   from Florian Westphal.

6) ctnetlink clamp timeout to INT_MAX if timeout is too large,
   otherwise timeout wraps around and it results in killing the
   entry that is being added immediately.

7) Missing CAP_NET_ADMIN checks in cthelper and xt_osf, due to
   no netns support. From Kevin Cernekee.

8) Missing maximum number of instructions checks in xt_bpf, patch
   from Jann Horn.

Closing a multicast socket after the final IPv4 address is deleted
from an interface can generate a membership report that uses the
source IP from a different interface.  The following test script, run
from an isolated netns, reproduces the issue:

    #!/bin/bash

    ip link add dummy0 type dummy
    ip link add dummy1 type dummy
    ip link set dummy0 up
    ip link set dummy1 up
    ip addr add 10.1.1.1/24 dev dummy0
    ip addr add 192.168.99.99/24 dev dummy1

    tcpdump -U -i dummy0 &

    sleep 1
    ip addr del 10.1.1.1/24 dev dummy0
    sleep 5
    kill %tcpdump

RFC 3376 specifies that the report must be sent with a valid IP source
address from the destination subnet, or from address 0.0.0.0.  Add an
extra check to make sure this is the case.

The MD5-key that belongs to a connection is identified by the peer's
IP-address. When we are in tcp_v4(6)_reqsk_send_ack(), we are replying
to an incoming segment from tcp_check_req() that failed the seq-number
checks.

Thus, to find the correct key, we need to use the skb's saddr and not
the daddr.

This bug seems to have been there since quite a while, but probably got
unnoticed because the consequences are not catastrophic. We will call
tcp_v4_reqsk_send_ack only to send a challenge-ACK back to the peer,
thus the connection doesn't really fail.

Now in sctp_setsockopt_reset_streams, it only does the check
optlen < sizeof(*params) for optlen. But it's not enough, as
params->srs_number_streams should also match optlen.

If the streams in params->srs_stream_list are less than stream
nums in params->srs_number_streams, later when dereferencing
the stream list, it could cause a slab-out-of-bounds crash, as
reported by syzbot.

This patch is to fix it by also checking the stream numbers in

Not all variants of the sh_eth hardware have Gigabit
support. Unfortunately, the current driver doesn't tell the PHY about
the limited MAC capabilities. Due to this, if you have a Gigabit
capable PHY, the PHY will advertise its Gigabit capability and
establish a link at 1Gbit/s, even though the MAC doesn't support it.

In order to avoid this, we use the recently introduced
phy_set_max_speed() to tell the PHY to not advertise speed higher than
100 MBit/s.

The purpose of this change is to fix the incorrect detection of the link
partner (LP) advertised capabilities which sometimes happens with this PHY
(roughly 1 time in a dozen)

This issue may cause the link to be negotiated at 10Mbps/Full or
10Mbps/Half when 100MBps/Full is actually possible. In some case, the link
is even completely broken and no communication is possible.

To detect the corruption, we must look for a magic undocumented bit in the
WOL bank (hint given by the SoC vendor kernel) but this is not enough to
cover all cases. We also have to look at the LPA ack. If the LP supports
Aneg but did not ack our base code when aneg is completed, we assume
something went wrong.

The detection of a corrupted LPA triggers a restart of the aneg process.
This solves the problem but may take up to 6 retries to complete.

Users of ptr_ring expect that it's safe to give the
data structure a pointer and have it be available
to consumers, but that actually requires an smb_wmb
or a stronger barrier.

In absence of such barriers and on architectures that reorder writes,
consumer might read an un=initialized value from an skb pointer stored
in the skb array.  This was observed causing crashes.

To fix, add memory barriers.  The barrier we use is a wmb, the
assumption being that producers do not need to read the value so we do
not need to order these reads.

 "One notable fix for kexec on Power9, where we were not clearing MMU
  PID properly which sometimes leads to hangs. Finally debugged to a

  A revert of a patch which tried to rework our panic handling to get
  more output on the console, but inadvertently broke reporting the
  panic to the hypervisor, which apparently people care about.

  Then a fix for an oops in the PMU code, and finally some s/%p/%px/ in
  xmon.

====================
pull-request: can 2017-12-08

this is a pull request of 6 patches for net/master.

Martin Kelly provides 5 patches for various USB based CAN drivers, that
properly cancel the URBs on adapter unplug, so that the driver doesn't
end up in an endless loop. Stephane Grosjean provides a patch to restart
the tx queue if zero length packages are transmitted.

wireless-drivers fixes for 4.15

Second set of fixes for 4.15. This time a lot of iwlwifi patches and
two brcmfmac patches. Most important here are the MIC and IVC fixes
for iwlwifi to unbreak 9000 series.

iwlwifi

* fix rate-scaling to not start lowest possible rate

* fix the TX queue hang detection for AP/GO modes

* fix the TX queue hang timeout in monitor interfaces

* fix packet injection

* remove a wrong error message when dumping PCI registers

* fix race condition with RF-kill

* tell mac80211 when the MIC has been stripped (9000 series)

* tell mac80211 when the IVC has been stripped (9000 series)

* add 2 new PCI IDs, one for 9000 and one for 22000

* fix a queue hang due during a P2P Remain-on-Channel operation

brcmfmac

* fix a race which sometimes caused a crash during sdio unbind

* fix a kernel-doc related build error

The macro used to access or set an RSS table entry was using an offset
of 8, while it should use an offset of 0. This lead to wrongly configure
the RSS table, not accessing the right entries.

tcp: RACK loss recovery bug fixes

This patch set has four minor bug fixes in TCP RACK loss recovery.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>

RACK skips an ACK unless it advances the most recently delivered
TX timestamp (rack.mstamp). Since RACK also uses the most recent
RTT to decide if a packet is lost, RACK should still run the
loss detection whenever the most recent RTT changes. For example,
an ACK that does not advance the timestamp but triggers the cwnd
undo due to reordering, would then use the most recent (higher)
RTT measurement to detect further losses.

When sender detects spurious retransmission, all packets
marked lost are remarked to be in-flight. However some may
be considered lost based on its timestamps in RACK. This patch
forces RACK to re-evaluate, which may be skipped previously if
the ACK does not advance RACK timestamp.

RACK does not test the loss recovery state correctly to compute
the reordering window. It assumes if lost_out is zero then TCP is
not in loss recovery. But it can be zero during recovery before
calling tcp_rack_detect_loss(): when an ACK acknowledges all
packets marked lost before receiving this ACK, but has not yet
to discover new ones by tcp_rack_detect_loss(). The fix is to
simply test the congestion state directly.
