81d184199e net/mlx4_core: Do not access comm channel if it has not yet been initialized
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.

9d2afba058 net/mlx4_en: Fix panic during reboot
Fix a kernel panic that occurs as a result of an asynchronous event
handled in roce_gid_mgmt:
mlx4_en_get_drvinfo is called and accesses freed resources.

This happens in a shutdown flow only, since pci device is destroyed
while netdevice is still alive.

8d59de8f7b net/mlx4_en: Process all completions in RX rings after port goes up
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.

aa0c08feae net/mlx4_core: Fix the resource-type enum in res tracker to conform to FW spec
The resource type enum in the resource tracker was incorrect.
RES_EQ was put in the position of RES_NPORT_ID (a FC resource).

Since the remaining resources maintain their current values,
and RES_EQ is not passed from slaves to the hypervisor in any
FW command, this change affects only the hypervisor.
Therefore, there is no backwards-compatibility issue.

ff57087f31 rds: debug messages are enabled by default
rds use Kconfig option called "RDS_DEBUG" to enable rds debug messages.
This option cause the rds Makefile to add -DDEBUG to the rds gcc command
line.

When CONFIG_DYNAMIC_DEBUG is enabled, the "DEBUG" macro is used by
include/linux/dynamic_debug.h to decide if dynamic debug prints should
be sent by default to the kernel log.

rds should not enable this macro for production builds. rds dynamic
debug work as expected follow this fix.

104ba78c98 packet: on direct_xmit, limit tso and csum to supported devices
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.

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.

96a8eb1eee bpf: fix samples to add fake KBUILD_MODNAME
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

Here are a few small char/misc driver fixes for reported issues.  The
 "biggest" are two binder fixes for reported issues that have been
 shipping in Android phones for a while now, the others are various fixes
 for reported problems.
 
 And there's a MAINTAINERS update for good measure.
 
 All have been in linux-next with no reported issues.

e4cabca549 inet: Fix missing return value in inet6_hash
As part of a series to implement faster SO_REUSEPORT lookups,
commit 086c653f58 ("sock: struct proto hash function may error")
added return values to protocol hash functions and
commit 496611d7b5 ("inet: create IPv6-equivalent inet_hash function")
implemented a new hash function for IPv6.  However, the latter does
not respect the former's convention.

This properly propagates the hash errors in the IPv6 case.

Saeed Mahameed says:

====================
Mellanox 100G mlx5 fixes 2016-10-25

This series contains some bug fixes for the mlx5 core and mlx5e driver.

From Daniel:
    - Cache line size determination at runtime, instead of using
      L1_CACHE_BYTES hard coded value, use cache_line_size()
    - Always Query HCA caps after setting them even on reset flow

From Mohamad:
    - Reorder netdev cleanup to uregister netdev before detaching it
      for the kernel to not complain about open resources such as vlans
    - Change the acl enable prototype to return status, for better error
      resiliency
    - Clear health sick bit when starting health poll after reset flow
    - Fix race between PCI error handlers and health work
    - PCI error recovery health care simulation, in case when the kernel
      PCI error handlers are not triggered for some internal firmware errors

From Noa:
    - Avoid passing dma address 0 to firmware when mapping system pages
      to the firmware

From Paul: Some straight forward flow steering fixes
    - Keep autogroups list ordered
    - Fix autogroups groups num not decreasing
    - Correctly initialize last use of flow counters

From Saeed:
    - Choose the nearest LRO timeout to the wanted one
      instead of blindly choosing "dev_cap.lro_timeout[2]"

This series has no conflict with the for-next pull request posted
earlier today ("Mellanox mlx5 core driver updates 2016-10-25").

6b276190c5 net/mlx5: Avoid passing dma address 0 to firmware
Currently the firmware can't work with a page with dma address 0.
Passing such an address to the firmware will cause the give_pages
command to fail.

To avoid this, in case we get a 0 dma address of a page from the
dma engine, we avoid passing it to FW by remapping to get an address
other than 0.

Mohamad Haj Yahia
04c0c1ab38 net/mlx5: PCI error recovery health care simulation
In case that the kernel PCI error handlers are not called, we will
trigger our own recovery flow.

The health work will give priority to the kernel pci error handlers to
recover the PCI by waiting for a small period, if the pci error handlers

We don't save pci state in case of manual recovery because it will ruin the
pci configuration space and we will lose dma sync.

05ac2c0b74 net/mlx5: Fix race between PCI error handlers and health work
Currently there is a race between the health care work and the kernel
pci error handlers because both of them detect the error, the first one
to be called will do the error handling.
There is a chance that health care will disable the pci after resuming
pci slot.
Also create a separate WQ because now we will have two types of health
works, one for the error detection and one for the recovery.

bf911e985d sctp: validate chunk len before actually using it
Andrey Konovalov reported that KASAN detected that SCTP was using a slab
beyond the boundaries. It was caused because when handling out of the
blue packets in function sctp_sf_ootb() it was checking the chunk len
only after already processing the first chunk, validating only for the
2nd and subsequent ones.

The fix is to just move the check upwards so it's also validated for the
1st chunk.

1e90a13d0c x86/smpboot: Init apic mapping before usage
The recent changes, which forced the registration of the boot cpu on UP
systems, which do not have ACPI tables, have been fixed for systems w/o
local APIC, but left a wreckage for systems which have neither ACPI nor
mptables, but the CPU has an APIC, e.g. virtualbox.

The boot process crashes in prefill_possible_map() as it wants to register
the boot cpu, which needs to access the local apic, but the local APIC is
not yet mapped.

There is no reason why init_apic_mapping() can't be invoked before
prefill_possible_map(). So instead of playing another silly early mapping
game, as the ACPI/mptables code does, we just move init_apic_mapping()
before the call to prefill_possible_map().

In hindsight, I should have noticed that combination earlier.

Sorry for the churn (also in stable)!
