efx_device_detach_sync() locks all TX queues before marking the device
detached and thus disabling further TX scheduling. But it can still
be interrupted by TX completions which then result in TX scheduling in
soft interrupt context. This will deadlock when it tries to acquire
a TX queue lock that efx_device_detach_sync() already acquired.
To avoid deadlock, we must use netif_tx_{,un}lock_bh().

While PCI card faces EEH errors, reset (usually hot reset) is
expected to recover from the EEH errors. After EEH core finishes
the reset, the driver callback (be_eeh_reset) is called and wait
the firmware to complete POST successfully. The original code would
return with error once detecting failure during POST stage. That
seems not enough.
The patch forces the driver (be_eeh_reset) to wait the firmware
completes POST until timeout, instead of returning error upon
detection POST failure immediately. Also, it would improve the
reliability of the EEH funtionality of the driver.

We should reset nf settings bond to the skb as ipip/ipgre do.
If not, the conntrack/nat info bond to the origin packet may continually
redirect the packet to vxlan interface causing a routing loop.
this is the scenario:
VETP VXLAN Gateway
/----\ /---------------\
| | | |
| vx+--+vx --NAT-> eth0+--> Internet
| | | |
\----/ \---------------/
when there are any packet coming from internet to the vetp, there will be lots
of garbage packets coming out the gateway's vxlan interface, but none actually
sent to the physical interface, because they are redirected back to the vxlan
interface in the postrouting chain of NAT rule, and dmesg complains:

Jeff Kirsher says:
===================
This series contains fixes to e1000e and igb.
The e1000e fix resolves an issue at 1000Mbps link speed, where one of the
MAC's internal clocks can be stopped for up to 4us when entering K1 (a
power mode of the MAC-PHY interconnect). If the MAC is waiting for
completion indications for 2 DMA write requests into Host memory
(e.g. descriptor writeback or Rx packet writing) and the
indications occur while the clock is stopped, both indications will be
missed by the MAC causing the MAC to wait for the completion indications
and be unable to generate further DMA write requests. This results in an
apparent hardware hang. The patch works-around the issue by disabling
the de-assertion of the clock request when 1000Mbps link is acquired (K1
must be disabled while doing this).
The igb fix to drop BUILD_BUG_ON check from igb_build_rx_buffer resolves
a build error on s390 devices. The igb driver was throwing a build error
due to the fact that a frame built using build_skb would be larger than 2K.
Since this is not likely to change at any point in the future we are better
off just dropping the check since we already had a check in
igb_set_rx_buffer_len that will just disable the usage of build_skb anyway.
The igb fix for i210 link setup changes the setup copper link function
to use a switch statement, so that the appropriate setup link function
is called for the given PHY types.
Lastly, the igb fix for a lockdep issue in igb_get_i2c_client resolves
the issue by re-factoring the initialization and usage of the i2c_client.

This flow happens when we get a failed single Tx response
on an AMPDU queue. In this case, the frame won't be sent
any more. So we need to move the window on the recipient
side. This is done by a BAR.
Now if we are in the following case: 10, 12 and 13 are ACKed
and 11 isn't.
10 11 12 13.
V X V V
Then, 11 will be sent 16 times as an MPDU (as oppsed to
A-MPDU). If this failed, we are entering the flow described
above. So we need to send a BAR with ssn = 12.
But in this case, the scheduler will tell us to free frames
up to 13 (included).
So, it is perfectly possible to get a failed single Tx
response on an AMPDU queue that makes the scheduler's ssn
jump by more than 1 single packet.

Recently in commit 8a964f44e0
("iwlwifi: always copy first 16 bytes of commands") we fixed
the problem that the hardware writes back to the command and
that could overwrite parts of the data that was still needed
and would thus be corrupted.
Investigating this problem more closely we found that this
write-back isn't really ordered very well with respect to
other DMA traffic. Therefore, it sometimes happened that the
write-back occurred after unmapping the command again which
is clearly an issue and could corrupt the next allocation
that goes to that spot, or (better) cause IOMMU faults.
To fix this, allocate coherent memory for the first 16 bytes
of each command, containing the write-back part, and use it
for all queues. All the dynamic DMA mappings only need to be
TO_DEVICE then. This ensures that even when the write-back
happens "too late" it can't hit memory that has been freed
or a mapping that doesn't exist any more.
Since now the actual command is no longer modified, we can
also remove CMD_WANT_HCMD and get rid of the DMA sync that
was necessary to update the scratch pointer.

Supporting 8K A-MSDU means that we need to allocate order 1
pages for every Rx packet. Even when there is no traffic.
This adds stress on the memory manager. The handling of
compound pages is also less trivial for the memory manager
and not using them will make the allocation code run faster
although I didn't really measure.
Eric also pointed out that having huge buffers with little
data in them is not very nice towards the TCP stack since
the truesize of the skb is huge. This doesn't allow TCP
to have a big Rx window.
See https://patchwork.kernel.org/patch/2167711/ for details.
Note that very few vendors will actually send A-MSDU.

The reason we mapped them bidirectionally was that not doing
so had caused IOMMU exceptions, due to the fact that the HW
writes back into the command. Now that the first part of the
command including the write-back part is always in the first
buffer, we don't need to map the remaining buffer(s) bidi
and can get rid of the special-casing for commands.
This is a requisite patch for another one to fix DMA mapping.

I'm not sure why, but the hlist for each entry iterators were conceived
list_for_each_entry(pos, head, member)
The hlist ones were greedy and wanted an extra parameter:
hlist_for_each_entry(tpos, pos, head, member)
Why did they need an extra pos parameter? I'm not quite sure. Not only
they don't really need it, it also prevents the iterator from looking
exactly like the list iterator, which is unfortunate.
Besides the semantic patch, there was some manual work required:
- Fix up the actual hlist iterators in linux/list.h
- Fix up the declaration of other iterators based on the hlist ones.
- A very small amount of places were using the 'node' parameter, this
was modified to use 'obj->member' instead.
- Coccinelle didn't handle the hlist_for_each_entry_safe iterator

On many different chips, important aspects of the MAC state are not
fully cleared by a warm reset. This can show up as tx/rx hangs, those
annoying "DMA failed to stop in 10 ms..." messages or other quirks.
On AR933x, the chip can occasionally get stuck in a way that only a
driver unload/reload or a reboot would bring it back to life.
With this patch, a full reset is issued when bringing the chip out of
FULL-SLEEP state (after idle), or if either Rx or Tx was not shut down
properly. This makes the DMA related error messages disappear completely
in my tests on AR933x, and the chip does not get stuck anymore.

The ath9k commit 2ef167557c
(ath9k: fix signal strength reporting issues) fixed an issue where the
reported per-frame signal strength reported to mac80211 was being
overwritten with an internal average. The same issue is also present
in ath9k_htc.
In addition to preventing the driver from overwriting the value, this
commit also ensures that the internal average (which is used for ANI)
only tracks beacons of the AP that we're connected to.

of an unset RSSI value, ATH_RSSI_DUMMY_MARKER, was supposed to have been

This USB ethernet adapter was purchased in anodyne packaging
from the computer store adjacent to linux.conf.au 2013 in
Canberra (Australia). A web search shows other recent
purchasers in Lancaster (UK) and Seattle (USA). Just like an
emergent virus, our age of e-commerce and airmail allows
underdocumented hardware to spread around the world instantly

Paige Thompson, infected via eBay, discovered that the HG20F9

This patch uses her discovery to update the restructured Asix
driver in the current kernel.
Just as some viruses inhabit seemingly-healthy cells, the
HG20F9 uses the Vendor ID 0x066b assigned to Linksys Inc.

Some fixes that should go into 3.9:
1. Fix packet corruption when using non-coherent RX DMA buffers.
2. Fix occasional watchdog misfiring when changing MTU or ring size.
These are longstanding bugs and should be fixed in stable as well, but
I'd like to review other recent fixes first and send a separate request
for stable inclusion.

When stations are removed while packets are in the queue,
we drain the queues first, and then remove the stations.
If this happens in AP mode while the interface is removed
the MAC context might be removed from the firmware before
we removed the station(s), resulting in a SYSASSERT 3421.
This is because we remove the MAC context from the FW in
stop_ap(), but only flush the station drain work later in
remove_interface().
Refactor the code a bit to have a common MAC context
removal preparation first to solve this.

The FH hardware will always write back to the scratch field
in commands, even host commands not just TX commands, which
can overwrite parts of the command. This is problematic if
the command is re-used (with IWL_HCMD_DFL_NOCOPY) and can
cause calibration issues.
Address this problem by always putting at least the first
16 bytes into the buffer we also use for the command header
and therefore make the DMA engine write back into this.
For commands that are smaller than 16 bytes also always map
enough memory for the DMA engine to write back to.

We must only ever stop TX queues when they are full or the net device
is not 'ready' so far as the net core, and specifically the watchdog,
is concerned. Otherwise, the watchdog may fire *immediately* if no
packets have been added to the queue in the last 5 seconds.
The device is ready if all the following are true:
(a) It has a qdisc
(b) It is marked present
(c) It is running
(d) The link is reported up
(a) and (c) are normally true, and must not be changed by a driver.
(d) is under our control, but fake link changes may disturb userland.
This leaves (b). We already mark the device absent during reset
and self-test, but we need to do the same during MTU changes and ring
reallocation. We don't need to do this when the device is brought
down because then (c) is already false.

We may currently allocate two RX DMA buffers to a page, and only unmap
the page when the second is completed. We do not sync the first RX
buffer to be completed; this can result in packet loss or corruption
if the last RX buffer completed in a NAPI poll is the first in a page
and is not DMA-coherent. (In the middle of a NAPI poll, we will
handle the following RX completion and unmap the page *before* looking
at the content of the first buffer.)

ring sizes are set in a single operation, which ever ring is not set will
silently have its ring count multiplied by the number of queues on the NIC until
it reaches a driver defined maxiumum value.
Fix it by not multiplying the rx and tx ring sizes by the number of queues in
the system, like every other driver. Tested by myself successfully.

Commit ee873fda3b ("gianfar: Pack struct
gfar_priv_grp into three cachelines") moved the irq number and names
off into a separate struct and created accessors for them. However
it was never tested with NET_POLL enabled, and so some conversions
that were simply overlooked went undetected until now.
Make the netpoll ones also use the gfar_irq() accessors.

Pull powerpc updates from Benjamin Herrenschmidt:
"So from the depth of frozen Minnesota, here's the powerpc pull request
for 3.9. It has a few interesting highlights, in addition to the
usual bunch of bug fixes, minor updates, embedded device tree updates
and new boards:
- Hand tuned asm implementation of SHA1 (by Paulus & Michael
Ellerman)
- Support for Doorbell interrupts on Power8 (kind of fast
thread-thread IPIs) by Ian Munsie
- Long overdue cleanup of the way we handle relocation of our open
firmware trampoline (prom_init.c) on 64-bit by Anton Blanchard
- Support for saving/restoring & context switching the PPR (Processor
Priority Register) on server processors that support it. This
allows the kernel to preserve thread priorities established by
userspace. By Haren Myneni.
- DAWR (new watchpoint facility) support on Power8 by Michael Neuling
- Ability to change the DSCR (Data Stream Control Register) which
controls cache prefetching on a running process via ptrace by
Alexey Kardashevskiy
- Support for context switching the TAR register on Power8 (new
branch target register meant to be used by some new specific
userspace perf event interrupt facility which is yet to be enabled)
by Ian Munsie.
- Improve preservation of the CFAR register (which captures the
origin of a branch) on various exception conditions by Paulus.
- Move the Bestcomm DMA driver from arch powerpc to drivers/dma where
it belongs by Philippe De Muyter
- Support for Transactional Memory on Power8 by Michael Neuling
(based on original work by Matt Evans). For those curious about
the feature, the patch contains a pretty good description."

The mlx4_en driver allocates the number of objects for the CPU affinity
reverse-map based on the number of rx rings of the device. However,
mlx4_assign_eq() calls irq_cpu_rmap_add() as many times as IRQ's are
assigned to EQ's, which can be as large as mlx4_dev->caps.comp_pool. If
caps.comp_pool is larger than rx_ring_num we will eventually hit the
BUG_ON() in cpu_rmap_add().
Fix this problem by allocating space for the maximum number of CPU
affinity reverse-map objects we might want to add.

Unload sequence for mwifiex PCIE driver is as follows:
1. Invoking cleanup module from kernel results into
pci_unregister_driver
2. Kernel invokes PCIE remove() handler which disconnects all
interfaces.
3. One step during disconnect is to clean PCIE TX rings.
During this we read txbd_rdptr from FW.
While loading driver next time, we see pci_enable_device()
results into system freeze. This may have happened because we
accessed PCI device after unregistering from bus driver.
Removing this ioread() operation resolves this bug.

Converting more ARM platforms to multiplatform support. This time, OMAP
gets converted, which is a major step since this is by far the largest
platform in terms of code size. The same thing happens to the vt8500
platform.
Conflicts include:
* Two mach/uncompress.h files are removed, the changes made to them
elsewhere can be discarded now.
* Moving the OMAP4 irq_match array has context clashes with turning
omap4_sar_ram_init into an omap_early_initcall()

Merge tag 'driver-core-3.9-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core
Pull driver core patches from Greg Kroah-Hartman:
"Here is the big driver core merge for 3.9-rc1
There are two major series here, both of which touch lots of drivers
all over the kernel, and will cause you some merge conflicts:
- add a new function called devm_ioremap_resource() to properly be
able to check return values.
- remove CONFIG_EXPERIMENTAL
Other than those patches, there's not much here, some minor fixes and
updates"
Fix up trivial conflicts

MR deregistration fails when memory windows are bound to the MR.
Handle such failures by propagating them to the caller ULP.

The MPT - Memory Protection Table - is used by both memory windows and
memory regions. Hence, all MPT references are relevant for both types
of memory objects. Rename the relevant functions to start with mpt_
instead of the current mr_ prefix.

Pull networking update from David Miller:
1) Checkpoint/restarted TCP sockets now can properly propagate the TCP
timestamp offset. From Andrey Vagin.
2) VMWARE VM VSOCK layer, from Andy King.
3) Much improved support for virtual functions and SR-IOV in bnx2x,
from Ariel ELior.
4) All protocols on ipv4 and ipv6 are now network namespace aware, and
all the compatability checks for initial-namespace-only protocols is
removed. Thanks to Tom Parkin for helping deal with the last major
holdout, L2TP.
5) IPV6 support in netpoll and network namespace support in pktgen,
from Cong Wang.
6) Multiple Registration Protocol (MRP) and Multiple VLAN Registration
Protocol (MVRP) support, from David Ward.
7) Compute packet lengths more accurately in the packet scheduler, from
Eric Dumazet.
8) Use per-task page fragment allocator in skb_append_datato_frags(),
also from Eric Dumazet.
9) Add support for connection tracking labels in netfilter, from
Florian Westphal.
10) Fix default multicast group joining on ipv6, and add anti-spoofing
checks to 6to4 and 6rd. From Hannes Frederic Sowa.
11) Make ipv4/ipv6 fragmentation memory limits more reasonable in modern
times, rearrange inet frag datastructures for better cacheline
locality, and move more operations outside of locking. From Jesper
Dangaard Brouer.
12) Instead of strict master <--> slave relationships, allow arbitrary
scenerios with "upper device lists". From Jiri Pirko.
13) Improve rate limiting accuracy in TBF and act_police, also from Jiri
Pirko.
14) Add a BPF filter netfilter match target, from Willem de Bruijn.
15) Orphan and delete a bunch of pre-historic networking drivers from
Paul Gortmaker.
16) Add TSO support for GRE tunnels, from Pravin B SHelar. Although
this still needs some minor bug fixing before it's %100 correct in
all cases.
17) Handle unresolved IPSEC states like ARP, with a resolution packet
queue. From Steffen Klassert.
18) Remove TCP Appropriate Byte Count support (ABC), from Stephen
Hemminger. This was long overdue.
19) Support SO_REUSEPORT, from Tom Herbert.
20) Allow locking a socket BPF filter, so that it cannot change after a
process drops capabilities.
21) Add VLAN filtering to bridge, from Vlad Yasevich.
22) Bring ipv6 on-par with ipv4 and do not cache neighbour entries in
the ipv6 routes, from YOSHIFUJI Hideaki.
