077cb37fcf ethtool: Use kcalloc instead of kmalloc for ethtool_get_strings
It seems that kernel memory can leak into userspace by a
kmalloc, ethtool_get_strings, then copy_to_user sequence.

Avoid this by using kcalloc to zero fill the copied buffer.

62fcce9104 ACPICA: Tables: Fix FADT dependency regression
Some logics actually relying on the existence of FADT, currently relies on
the number of loaded tables. This false dependency can easily trigger
regressions. One of them has been introduced by commit 8ec3f45907
(ACPICA: Tables: Fix global table list issues by removing fixed table).

The commit changing the fixed table indexes results in the change of FADT
table index, originally, it was 3 (thus the installed table count should be
greater than 4), while currently it is 0 (and the installed table count may
be 3).

This patch fixes this regression by cleaning up the code. Lv Zheng.

e79b202c63 Partially revert "clk: mvebu: Convert to clk_hw based provider APIs"
This partially reverts commit eca61c9ff2.

Thomas reports that it causes regressions on Armada XP devices.
This is because of_clk_get_parent_name() relies on the property
'clock-output-names' to resolve the name of a clock's parent,
without trying to get the clock from the framework and call
__clk_get_name(). Given that Armada XP devices don't have the
'clock-output-names' property, of_clk_get_parent_name() returns
the name of the node which doesn't match the actual parent
clock's name at all, causing CPU clocks to never link up with
their parents.

b10d92a54d KVM: x86: fix RSM into 64-bit protected mode
In order to get into 64-bit protected mode, you need to enable
paging while EFER.LMA=1.  For this to work, CS.L must be 0.
Currently, we load the segments before CR0 and CR4, which means
that if RSM returns into 64-bit protected mode CS.L is already 1
and everything breaks.

Luckily, CS.L=0 is always the case when executing RSM, because it
is forbidden to execute RSM from 64-bit protected mode.  Hence it
is enough to load CR0 and CR4 first, and only then the segments.

0f8b8e28fb tipc: eliminate risk of stalled link synchronization
In commit 6e498158a8 ("tipc: move link synch and failover to link aggregation level")
we introduced a new mechanism for performing link failover and
synchronization. We have now detected a bug in this mechanism.

During link synchronization we use the arrival of any packet on
the tunnel link to trig a check for whether it has reached the
synchronization point or not. This has turned out to be too
permissive, since it may cause an arriving non-last SYNCH packet to
end the synch state, just to see the next SYNCH packet initiate a
new synch state with a new, higher synch point. This is not fatal,
but should be avoided, because it may significantly extend the
synchronization period, while at the same time we are not allowed
to send NACKs if packets are lost. In the worst case, a low-traffic
user may see its traffic stall until a LINK_PROTOCOL state message
trigs the link to leave synchronization state.

At the same time, LINK_PROTOCOL packets which happen to have a (non-
valid) sequence number lower than the tunnel link's rcv_nxt value will
be consistently dropped, and will never be able to resolve the situation
described above.

We fix this by exempting LINK_PROTOCOL packets from the sequence number
check, as they should be. We also reduce (but don't completely
eliminate) the risk of entering multiple synchronization states by only
allowing the (logically) first SYNCH packet to initiate a synchronization
state. This works independently of actual packet arrival order.

Fixes: commit 6e498158a8 ("tipc: move link synch and failover to link aggregation level")

Revert the commit e2ca690b65 ("ipv4/icmp: redirect messages
can use the ingress daddr as source"), which tried to introduce a more
suitable behaviour for ICMP redirect messages generated by VRRP routers.
However RFC 5798 section 8.1.1 states:

    The IPv4 source address of an ICMP redirect should be the address
    that the end-host used when making its next-hop routing decision.

while said commit used the generating packet destination
address, which do not match the above and in most cases leads to
no redirect packets to be generated.

Jeff Kirsher says:

====================
Intel Wired LAN Driver Updates 2015-10-13

This series contains updates to i40e, i40evf, ixgbe and fm10k.

Carolyn cleans up ndo_bridge_getlink() by flagging a parameter as
__always_unused, since it is never used.  Adds a member to the nvm_info
struct to store OEM version info to be output either by OID or ethtool.

Neerav cleans up a remaining bit shift to use BIT() macro.

Mitch fixes the i40evf driver to properly handle calls to its
ndo_set_mac_address() method.  It did not properly check to see if the
override would be allowed by the PF driver, and it never removed the old
address from its filter list.  Cleaned up the use of
i40e_enable_vf_mappings() in i40e_alloc_vfs(), since it is just redundant
since we already call it by i40e_reset_vf().  Fixed a possible panic
in some circumstances where the firmware may fail to allocate a VSI for
a VF by checking the return value from i40e_alloc_vf_res() and don't
try to configure the device further if it failed.

Greg fixes the parsing of CEE App TLVs so the caller does not have to
consider whether the App came from a CEE or IEEE DCBx negotiation.

Shannon moves the device ids into a standalone file due to the desire
to write user-land drivers (and other requests) without needing the rest
of the include files.

Catherine adds the ability to save the module information from
get_phy_capabilities() to be used to determine which speeds the module
supports.  Also cleaned up the PHY structure by removing unused members
and add the ability to store the PHY capabilities reported by the
firmware.

Emil modifies ixgbe to ensure that flow control packets initiated by the
VF are dropped and reported as spoofed.

Jacob cleans up the fm10k driver to avoid buffer overflow by using
sprintf(), so convert to using snprintf().  Also fixed the use of an
enum as a boolean, so check for the actual value of NETREG_UNINITIALIZED
in case it ever changes from the current value of zero.

v2: Dropped patch 11 of the original series, which added functions that
    were never used.

60a188a271 mwifiex: remove USB8897 chipset support
We don't have any customer using this chipset via USB
interface. if both mwifiex_pcie and mwifiex_usb modules
are enabled by user, sometimes mwifiex_usb wins the race
even if user wants wlan interface to be on PCIe and
USB for bluetooth. This patch solves the problem.

406df18f1f ath9k: Fix NF CCA limits for AR9287 and AR9227
The FreeBSD driver [0] uses the same 2G values as for the AR9280 chips.
Using the same values in ath9k results in much better throughput for me.

Before this patch I had a huge amount of packet loss (sometimes up to
40%) and the max transfer speed was somewhere around 5Mbit/s. With this
patch applied I have zero packet loss and ten times the throughput.
My device uses a AR9227 which is the PCI variant of the AR9287.

f1d2b4d338 rtlwifi: rtl818x: Move drivers into new realtek directory
Now that a new mac80211-based driver for Realtek devices has been submitted,
it is time to reorganize the directories. Rather than having directories
rtlwifi and rtl818x be in drivers/net/wireless/, they will now be in
drivers/net/wireless/realtek/. This change simplifies the directory
structure, but does not result in any configuration changes that are
visable to the user.

f079fa005a ixgbe: add flow control ethertype to the anti-spoofing filter
This patch makes sure that flow control packets initiated by the VF are
dropped and reported as spoofed.

Flow control packets can be used to limit the throughput or as DOS
attack when generated from a VF. Flow control is not supported per VF
hence any pause frames generated from a VF are considered malicious.

Also cleaned up indentation and some redundant comments.

fc72dbce09 i40e/i40evf: Refactor PHY structure and add phy_capabilities enum
Remove unused members in the PHY structure and add a new member to store
all the capabilities the PHY has as reported by the FW. This information
will help us determine what speeds the device is capable of when link is
down.

Also add an enum to decode the PHY types the NVM is capable of.
Use the phy_types variable to determine what phy types are possible
when link is down instead of device id as it will be more accurate.

When on a backplane device, we do not support changing any settings,
however we should display all the phy_types we are capable of so if we
see a backplane dev ID set supported and advertised purely based on
the phy_types variable.

0a862b43ac i40e/i40evf: Add module_types and update_link_info
Add a module_types variable to the link_info struct to save the module
information from get_phy_capabilities. This information can be used to
determine which speeds the module supports.

Also add a new function update_link_info which updates the module_types
parameter and then calls get_link_info. This function should be called
in place of get_link_info so that the module_types variable stays
up-to-date with the rest of the link information.

The EAS table does not reflect the values that are actually returned,
so instead, basing these values on the Ethernet compliance codes
specified in table 33 of SFF-8436 as these have been accurate.

Use the new variable in ethtool to differentiate between a 10G/1G dual
speed fiber module and a 10G only module.

21be99ec4e i40e: don't panic on VSI allocation failure
In some circumstances, the firmware may fail to allocate a VSI for a VF.
When this happens, the driver does not react well to the bad news and
has a panic attack.

To fix this problem, check the return value from i40e_alloc_vf_res and
don't try to configure the device further if it failed. Additionally,
explicitly clear the INIT bit when we free VF resources, so that this
bit will be in the proper state in the failure case, and won't blow up
elsewhere.
