The current binding document only describes a single interrupt. Update the
document by adding the 2 other interrupts.

The driver currently only uses a single interrupt. The HW is however able
to using IRQ grouping to split TX and RX onto separate GIC irqs.

Intel Wired LAN Driver Updates 2016-04-13

This series contains updates to i40e, i40evf and fm10k.

Alex fixes a bug introduced earlier based on his interpretation of the
XL710 datasheet.  The actual limit for fragments with TSO and a skbuff
that has payload data in the header portion of the buffer is actually
only 7 fragments and the skb-data portion counts as 2 buffers, one for
the TSO header, and the one for a segment payload buffer.

Jacob fixes a bug where in a previous refactor of the code broke
multi-bit updates for VFs.  The problem occurs because a multi-bit
request has a non-zero length, and the PF would simply drop any
request with the upper 16 bits set.

For local routes that require a particular output interface we do not want
to cache the result.  Caching the result causes incorrect behaviour when
there are multiple source addresses on the interface.  The end result
being that if the intended recipient is waiting on that interface for the
packet he won't receive it because it will be delivered on the loopback
interface and the IP_PKTINFO ipi_ifindex will be set to the loopback
interface as well.

This can be tested by running a program such as "dhcp_release" which
attempts to inject a packet on a particular interface so that it is
received by another program on the same board.  The receiving process
should see an IP_PKTINFO ipi_ifndex value of the source interface
(e.g., eth1) instead of the loopback interface (e.g., lo).  The packet
will still appear on the loopback interface in tcpdump but the important
aspect is that the CMSG info is correct.

Sample dhcp_release command line:

   dhcp_release eth1 192.168.204.222 02:11:33:22:44:66

The VF uses a multi-bit update request to clear unused VLANs whenever it
resets. However, an accident in a previous refector broke multi-bit
updates for VFs, due to misreading a comment in fm10k_vf.c and
attempting to reduce code duplication. The problem occurs because
a multi-bit request has a non-zero length, and the PF would simply drop
any request with the upper 16 bits set.

We can't simply remove the check of the upper 16 bits and the call to
fm10k_iov_select vid, because this would remove the checks for default
VID and for ensuring no other VLANs can be enabled except pf_vid when it
has been set. To resolve that issue, this revision uses the
iov_select_vid when we have a single-bit update, and denies any
multi-bit update when the VLAN was administratively set by the PF. This
should be ok since the PF properly updates VLAN_TABLE when it assigns
the PF vid. This ensures that requests to add or remove the PF vid work
as expected, but a rogue VF could not use the multi-bit update as
a loophole to attempt receiving traffic on other VLANs.

This patch addresses a bug introduced based on my interpretation of the
XL710 datasheet.  Specifically section 8.4.1 states that "A single transmit
packet may span up to 8 buffers (up to 8 data descriptors per packet
including both the header and payload buffers)."  It then later goes on to
say that each segment for a TSO obeys the previous rule, however it then
refers to TSO header and the segment payload buffers.

I believe the actual limit for fragments with TSO and a skbuff that has
payload data in the header portion of the buffer is actually only 7
fragments as the skb->data portion counts as 2 buffers, one for the TSO
header, and one for a segment payload buffer.

If a requested extension exists as module and is not loaded,

Reproduced with limit match: Given xt_limit and ebt_limit both built as

  modprobe xt_limit
  ebtables -I INPUT --limit 1/s -j ACCEPT

The fix is to make ebt_check_match() distrust a found NFPROTO_UNSPEC

A non-privileged user can create a netlink socket with the same port_id as
used by an existing open nl80211 netlink socket (e.g. as used by a hostapd
process) with a different protocol number.

Closing this socket will then lead to the notification going to nl80211's
socket release notification handler, and possibly cause an action such as
removing a virtual interface.

Fix this issue by checking that the netlink protocol is NETLINK_GENERIC.
Since generic netlink has no notifier chain of its own, we can't fix the
problem more generically.

ifupdown2 found a kernel bug with IPv6 routes and movement from the main
table to the VRF table. Sequence of events:

Create the interface and add addresses:
    ip link add dev eth4.105 link eth4 type vlan id 105
    ip addr add dev eth4.105 8.105.105.10/24
    ip -6 addr add dev eth4.105 2008:105:105::10/64

At this point IPv6 has inserted a prefix route in the main table even
though the interface is 'down'. From there the VRF device is created:
    ip link add dev vrf105 type vrf table 105
    ip addr add dev vrf105 9.9.105.10/32
    ip -6 addr add dev vrf105 2000:9:105::10/128
    ip link set vrf105 up

Then the interface is enslaved, while still in the 'down' state:
    ip link set dev eth4.105 master vrf105

Since the device is down the VRF driver cycling the device does not
send the NETDEV_UP and NETDEV_DOWN but rather the NETDEV_CHANGE event
which does not flush the routes inserted prior.

When the link is brought up
    ip link set dev eth4.105 up

the prefix route is added in the VRF table, but does not remove
the route from the main table.

Fix by handling the NETDEV_CHANGEUPPER event similar what was implemented
for IPv4 in 7f49e7a3 ("net: Flush local routes when device changes vrf
association")

Vivek reported a kernel exception deleting a VRF with an active
connection through it. The root cause is that the socket has a cached
reference to a dst that is destroyed. Converting the dst_destroy to
dst_release and letting proper reference counting kick in does not
work as the dst has a reference to the device which needs to be released
as well.

I talked to Hannes about this at netdev and he pointed out the ipv4 and
ipv6 dst handling has dst_ifdown for just this scenario. Rather than
continuing with the reinvented dst wheel in VRF just remove it and
leverage the ipv4 and ipv6 versions.

One such case involved the Firmware sending a "Flush Token" through the
ULP-TX -> ULP-RX path for an Ethernet TX Queue being freed in order to
make sure there weren't any remaining TX Work Requests in the pipeline.
But the return path was stalled by Ingress Data unable to be delivered to

All existing users of NETLINK_URELEASE use it to clean up resources that
were previously allocated to a socket via some command. As a result, no
users require getting this notification for unbound sockets.

Sending it for unbound sockets, however, is a problem because any user
(including unprivileged users) can create a socket that uses the same ID
as an existing socket. Binding this new socket will fail, but if the
NETLINK_URELEASE notification is generated for such sockets, the users
thereof will be tricked into thinking the socket that they allocated the
resources for is closed.

In the nl80211 case, this will cause destruction of virtual interfaces
that still belong to an existing hostapd process; this is the case that
Dmitry noticed. In the NFC case, it will cause a poll abort. In the case
of netlink log/queue it will cause them to stop reporting events, as if
NFULNL_CFG_CMD_UNBIND/NFQNL_CFG_CMD_UNBIND had been called.

Fix this problem by checking that the socket is bound before generating
the NETLINK_URELEASE notification.

Currently on high rate SCTP streams the heartbeat timer refresh can
consume quite a lot of resources as timer updates are costly and it
contains a random factor, which a) is also costly and b) invalidates
mod_timer() optimization for not editing a timer to the same value.
It may even cause the timer to be slightly advanced, for no good reason.

As suggested by David Laight this patch now removes this timer update
from hot path by leaving the timer on and re-evaluating upon its
expiration if the heartbeat is still needed or not, similarly to what is
done for TCP. If it's not needed anymore the timer is re-scheduled to
the new timeout, considering the time already elapsed.

For this, we now record the last tx timestamp per transport, updated in
the same spots as hb timer was restarted on tx. Also split up
sctp_transport_reset_timers into sctp_transport_reset_t3_rtx and
sctp_transport_reset_hb_timer, so we can re-arm T3 without re-arming the
heartbeat one.

On loopback with MTU of 65535 and data chunks with 1636, so that we
have a considerable amount of chunks without stressing system calls,
netperf -t SCTP_STREAM -l 30, perf looked like this before:

Pull staging and IIO driver fixes from Greg KH:
 "Here are some IIO driver fixes, along with two staging driver fixes
  for 4.6-rc3.

  One staging driver patch reverts the deletion of a driver that
  happened in 4.6-rc1.  We thought that laptop.org was dead, but it's
  still alive and kicking, and has users that were mad we broke their
  hardware by deleting a driver for their machines.  So that driver is
  added back and everyone is happy again.

  All of these have been in linux-next for a while with no reported
  issues"

Pull SCSI fixes from James Bottomley:
 "This is a set of eight fixes.

  Two are trivial gcc-6 updates (brace additions and unused variable
  removal).  There's a couple of cxlflash regressions, a correction for
  sd being overly chatty on revalidation (causing excess log increases).
  A VPD issue which could crash USB devices because they seem very
  intolerant to VPD inquiries, an ALUA deadlock fix and a mpt3sas buffer
  overrun fix"

Pull power management and ACPI fixes from Rafael Wysocki:
 "Fixes for some issues discovered after recent changes and for some
  that have just been found lately regardless of those changes
  (intel_pstate, intel_idle, PM core, mailbox/pcc, turbostat) plus
  support for some new CPU models (intel_idle, Intel RAPL driver,
  turbostat) and documentation updates (intel_pstate, PM core).

  Specifics:

   - intel_pstate fixes for two issues exposed by the recent switch over
     from using timers and for one issue introduced during the 4.4 cycle
     plus new comments describing data structures used by the driver
     (Rafael Wysocki, Srinivas Pandruvada).

   - intel_idle fixes related to CPU offline/online (Richard Cochran).

   - intel_idle support (new CPU IDs and state definitions mostly) for
     Skylake-X and Kabylake processors (Len Brown).

   - PCC mailbox driver fix for an out-of-bounds memory access that may
     cause the kernel to panic() (Shanker Donthineni).

   - New (missing) CPU ID for one apparently overlooked Haswell model in
     the Intel RAPL power capping driver (Srinivas Pandruvada).

   - Fix for the PM core's wakeup IRQs framework to make it work after
     wakeup settings reconfiguration from sysfs (Grygorii Strashko).

   - Runtime PM documentation update to make it describe what needs to
     be done during device removal more precisely (Krzysztof Kozlowski).

   - Stale comment removal cleanup in the cpufreq-dt driver (Viresh
     Kumar).

   - turbostat utility fixes and support for Broxton, Skylake-X and
     Kabylake processors (Len Brown)"
