Intel Wired LAN Driver Updates 2016-10-27
This series contains fixes to ixgbe and i40e.
Emil fixes a NULL pointer dereference when a macvlan interface is brought
up while the PF is still down.
David root caused the original panic that was fixed by commit id
(a036244c06 "i40e: Fix kernel panic on enable/disable LLDP") and the
fix was not quite correct, so removed the get_default_tc() and replaced
it with a #define since there is only one TC supported as a default.
Guilherme Piccoli fixes an issue where if we modprobe the driver module
without enough MSI-X interrupts, then unload the module and reload it
again, the kernel would crash. So if we fail to allocate enough MSI-X
interrupts, we should disable them since they were previously enabled.
Huaibin Wang found that the order of the arguments for
ndo_dflt_bridge_getlink() were in the correct order, so fix the order.

Pull x86 bugfix from Thomas Gleixner:
"A single bugfix for the recent changes related to registering the boot
cpu when this has not happened before prefill_possible_map().
The main problem with this change got fixed already, but we missed the
case where the local APIC is not yet mapped, when prefill_possible_map()
is invoked, so the registration of the boot cpu which has the APIC bit
set in CPUID will explode.
I should have seen that issue earlier, but all I can do now is feeling
embarassed"

Following the previous patch, as an optimization, the slave will

mlx4_en_DUMP_ETH_STATS took the *counter mutex* and then
called the FW command, with WRAPPED attribute. As a result, the fw command
is wrapped on the Hypervisor when it calls mlx4_en_DUMP_ETH_STATS.
The FW command wrapper flow on the hypervisor takes the *slave_cmd_mutex*
during processing.
At the same time, a VF could be in the process of coming up, and could
call mlx4_QUERY_FUNC_CAP. On the hypervisor, the command flow takes the
*slave_cmd_mutex*, then executes mlx4_QUERY_FUNC_CAP_wrapper.
mlx4_QUERY_FUNC_CAP wrapper calls mlx4_get_default_counter_index(),
which takes the *counter mutex*. DEADLOCK.
The fix is that the DUMP_ETH_STATS fw command should be called with
the NATIVE attribute, so that on the hypervisor, this command does not
enter the wrapper flow.
Since the Hypervisor no longer goes through the wrapper code, we also
simply return 0 in mlx4_DUMP_ETH_STATS_wrapper (i.e.the function succeeds,
but the returned data will be all zeroes).
No need to test if it is the Hypervisor going through the wrapper.

In the Hypervisor, there are several FW commands which are invoked
before the comm channel is initialized (in mlx4_multi_func_init).
These include MOD_STAT_CONFIG, QUERY_DEV_CAP, INIT_HCA, and others.
If any of these commands fails, say with a timeout, the Hypervisor
driver enters the internal error reset flow. In this flow, the driver
attempts to notify all slaves via the comm channel that an internal error
has occurred.
Since the comm channel has not yet been initialized (i.e., mapped via
ioremap), this will cause dereferencing a NULL pointer.
To fix this, do not access the comm channel in the internal error flow
if it has not yet been initialized.

Currently there is a race between incoming traffic and
initialization flow. HW is able to receive the packets
after INIT_PORT is done and unicast steering is configured.
Before we set priv->port_up NAPI is not scheduled and
receive queues become full. Therefore we never get
new interrupts about the completions.
This issue could happen if running heavy traffic during
bringing port up.
The resolution is to schedule NAPI once port_up is set.
If receive queues were full this will process all cqes
and release them.

40GbE Intel Wired LAN Driver Updates 2016-10-28
This series contains updates to i40e and i40evf only.
Carolyn provides a couple of fixes, first resolving a problem in the
client interface that was causing random stack traces in the RDMA driver
which was due to a timing related NULL pointer dereference. Fixed a
problem where it could take a very long time to print the link down
notification, by changing how often we update link info from firmware.
Alex provides a number of changes, first is a re-write of the bust wait
loop in the Flow Director transmit function to reduce code size. Cleans
up unused code in favor of the same functionality which can be inlined.
Dropped the functionality for SCTP since we cannot currently support it.
Cleans up redundant code in the receive clean-up path. Finally cleaned
up the convoluted configuration for how the driver handled the debug
flags contained in msg_level.
Filip fixes an incorrect bit mask which was being used for testing the
"get link status". Cleaned up a workaround that is no longer needed
for production NICs and was causing frames to pass while disregarding
the VLAN tagging.
Mitch brings another fix for the client interface supporting the VF RDMA
driver to allow clients to recover from reset by re-opening existing
clients.
Alan fixes a bug in which a "perfect storm" can occur and cause interrupts
to fail to be correctly affinitized.
Lihong fixes a confusing dmesg reported when users were using ethtool -L
option.

This reverts commit e3f74b841d
("hv_netvsc: report vmbus name in ethtool")'
because of problem introduced by commit f9a56e5d6a0ba
("Drivers: hv: make VMBus bus ids persistent").
This changed the format of the vmbus name and this new format is too
long to fit in the bus_info field of ethtool.

When transmitting on a packet socket with PACKET_VNET_HDR and
PACKET_QDISC_BYPASS, validate device support for features requested
in vnet_hdr.
Drop TSO packets sent to devices that do not support TSO or have the
feature disabled. Note that the latter currently do process those
packets correctly, regardless of not advertising the feature.
Because of SKB_GSO_DODGY, it is not sufficient to test device features
with netif_needs_gso. Full validate_xmit_skb is needed.
Switch to software checksum for non-TSO packets that request checksum
offload if that device feature is unsupported or disabled. Note that
similar to the TSO case, device drivers may perform checksum offload
correctly even when not advertising it.
When switching to software checksum, packets hit skb_checksum_help,
which has two BUG_ON checksum not in linear segment. Packet sockets
always allocate at least up to csum_start + csum_off + 2 as linear.
Tested by running github.com/wdebruij/kerneltools/psock_txring_vnet.c

There is an old warning about mlx4_SW2HW_EQ_wrapper on x86:

ethernet/mellanox/mlx4/resource_tracker.c:3071:10: error: ‘eq’ may be used uninitialized in this function [-Werror=maybe-uninitialized]
The problem here is that gcc won't track the state of the variable
across a spin_unlock. Moving the assignment out of the lock is
safe here and avoids the warning.

This patch updates skb->protocol to ETH_P_IPV6 in ip6_tnl_xmit() when an
IPv6 header is installed to a socket buffer.
This is not a cosmetic change. Without updating this value, GSO packets
transmitted through an ipip6 tunnel have the protocol of ETH_P_IP and
skb_mac_gso_segment() will attempt to call gso_segment() for IPv4,
which results in the packets being dropped.

Some of the sample files are causing issues when they are loaded with tc
and cls_bpf, meaning tc bails out while trying to parse the resulting ELF
file as program/map/etc sections are not present, which can be easily
spotted with readelf(1).
Currently, BPF samples are including some of the kernel headers and mid
term we should change them to refrain from this, really. When dynamic
debugging is enabled, we bail out due to undeclared KBUILD_MODNAME, which
is easily overlooked in the build as clang spills this along with other
noisy warnings from various header includes, and llc still generates an
ELF file with mentioned characteristics. For just playing around with BPF
examples, this can be a bit of a hurdle to take.
Just add a fake KBUILD_MODNAME as a band-aid to fix the issue, same is
done in xdp*_kern samples already.
