Pull networking updates from David Miller:
"Much more accumulated than I would have liked due to an unexpected
bout with a nasty flu:
1) AH and ESP input don't set ECN field correctly because the
transport head of the SKB isn't set correctly, fix from Li
RongQing.
2) If netfilter conntrack zones are disabled, we can return an
uninitialized variable instead of the proper error code. Fix from
Borislav Petkov.
3) Fix double SKB free in ath9k driver beacon handling, from Felix
Feitkau.
4) Remove bogus assumption about netns cleanup ordering in
nf_conntrack, from Pablo Neira Ayuso.
5) Remove a bogus BUG_ON in the new TCP fastopen code, from Eric
Dumazet. It uses spin_is_locked() in it's test and is therefore
unsuitable for UP.
6) Fix SELINUX labelling regressions added by the tuntap multiqueue
changes, from Paul Moore.
7) Fix CRC errors with jumbo frame receive in tg3 driver, from Nithin
Nayak Sujir.
8) CXGB4 driver sets interrupt coalescing parameters only on first
queue, rather than all of them. Fix from Thadeu Lima de Souza
Cascardo.
9) Fix regression in the dispatch of read/write registers in dm9601
driver, from Tushar Behera.
10) ipv6_append_data miscalculates header length, from Romain KUNTZ.
11) Fix PMTU handling regressions on ipv4 routes, from Steffen
Klassert, Timo Teräs, and Julian Anastasov.
12) In 3c574_cs driver, add necessary parenthesis to "x << y & z"
expression. From Nickolai Zeldovich.
13) macvlan_get_size() causes underallocation netlink message space,
fix from Eric Dumazet.
14) Avoid division by zero in xfrm_replay_advance_bmp(), from Nickolai
Zeldovich. Amusingly the zero check was already there, we were
just performing it after the modulus :-)
15) Some more splice bug fixes from Eric Dumazet, which fix things
mostly eminating from how we now more aggressively use high-order
pages in SKBs.
16) Fix size calculation bug when freeing hash tables in the IPSEC
xfrm code, from Michal Kubecek.
17) Fix PMTU event propagation into socket cached routes, from Steffen

major problems in normal operation, from Timo Teräs.
21) virtio-net set affinity and select queue don't handle
discontiguous cpu numbers properly, fix from Wanlong Gao.
22) Fix a route refcounting issue in loopback driver, from Eric
Dumazet. There's a similar fix coming that we might add to the
macvlan driver as well.

Running AIO is pinning inode in memory using file reference. Once AIO
is completed using aio_complete(), file reference is put and inode can
be freed from memory. So we have to be sure that calling aio_complete()
is the last thing we do with the inode.

When the new inode verify in xfs_iread() fails, the create
transaction is aborted and a shutdown occurs. The subsequent unmount
then hangs in xfs_wait_buftarg() on a buffer that has an elevated
hold count. Debug showed that it was an AGI buffer getting stuck:
[ 22.576147] XFS (vdb): buffer 0x2/0x1, hold 0x2 stuck
[ 22.976213] XFS (vdb): buffer 0x2/0x1, hold 0x2 stuck
[ 23.376206] XFS (vdb): buffer 0x2/0x1, hold 0x2 stuck
[ 23.776325] XFS (vdb): buffer 0x2/0x1, hold 0x2 stuck
The trace of this buffer leading up to the shutdown (trimmed for
brevity) looks like:
xfs_buf_init: bno 0x2 nblks 0x1 hold 1 caller xfs_buf_get_map
xfs_buf_get: bno 0x2 len 0x200 hold 1 caller xfs_buf_read_map

xfs_buf_rele: bno 0x2 nblks 0x1 hold 3 caller xfs_buf_item_unlock
And that is the AGI buffer from cold cache read into memory to
transaction abort. You can see at transaction abort the bli is dirty
and only has a single reference. The item is not pinned, and it's
not in the AIL. Hence the only reference to it is this transaction.
The problem is that the xfs_buf_item_unlock() call is dropping the
last reference to the xfs_buf_log_item attached to the buffer (which
holds a reference to the buffer), but it is not freeing the
xfs_buf_log_item. Hence nothing will ever release the buffer, and
the unmount hangs waiting for this reference to go away.
The fix is simple - xfs_buf_item_unlock needs to detect the last
reference going away in this case and free the xfs_buf_log_item to
release the reference it holds on the buffer.

There is a window on small filesytsems where specualtive
preallocation can be larger than that ENOSPC throttling thresholds,
resulting in specualtive preallocation trying to reserve more space
than there is space available. This causes immediate ENOSPC to be
triggered, prealloc to be turned off and flushing to occur. One the
next write (i.e. next 4k page), we do exactly the same thing, and so
effective drive into synchronous 4k writes by triggering ENOSPC
flushing on every page while in the window between the prealloc size
and the ENOSPC prealloc throttle threshold.
Fix this by checking to see if the prealloc size would consume all
free space, and throttle it appropriately to avoid premature
ENOSPC...

When _xfs_buf_find is passed an out of range address, it will fail
to find a relevant struct xfs_perag and oops with a null
dereference. This can happen when trying to walk a filesystem with a
metadata inode that has a partially corrupted extent map (i.e. the
block number returned is corrupt, but is otherwise intact) and we
try to read from the corrupted block address.
In this case, just fail the lookup. If it is readahead being issued,
it will simply not be done, but if it is real read that fails we
will get an error being reported. Ideally this case should result
in an EFSCORRUPTED error being reported, but we cannot return an
error through xfs_buf_read() or xfs_buf_get() so this lookup failure
may result in ENOMEM or EIO errors being reported instead.

The reset handler code is used for either UP or SMP. To make Tegra device
can compile for UP. It needs to be moved to another file that is not SMP
only. This is because the reset handler also be needed by CPU idle
"powered-down" mode. So we also need to put the reset handler init function
in non-SMP only and init them always.
And currently the implementation of the reset handler to know which CPU is
OK to bring up was identital with "cpu_present_mask". But the
"cpu_present_mask" did not initialize yet when the reset handler init
function was moved to init early function. We use the "cpu_possible_mask"
to replace "cpu_present_mask". Then it can work on both UP and SMP case.

Updating the cache maintenance order before CPU shutdown when doing CPU
hotplug.
The old order:
* clean L1 by flush_cache_all
* exit SMP
* CPU shutdown
Adapt to:
* disable L1 data cache by clear C bit
* clean L1 by v7_flush_dcache_louis
* exit SMP
* CPU shutdown
For CPU hotplug case, it's no need to do "flush_cache_all". And we should
disable L1 data cache before clean L1 data cache. Then leaving the SMP
coherency.

The power up sequence is different on the cold boot CPU and the CPU
that resumed from the hotplug. For the cold boot CPU, it was been power
gated as default. To power up the cold boot CPU, the power should be
un-gated by un toggling the power gate register manually.
For the CPU that resumed from the hotplug, after un-halted the CPU. The
flow controller will un-gate the power of the CPU. No need to manually
control, just wait the power be resumed and continue the power up
sequence after the CPU power is ready.

The IOMMU may stop processing page translations due to a perceived lack
of credits for writing upstream peripheral page service request (PPR)
or event logs. If the L2B miscellaneous clock gating feature is enabled
the IOMMU does not properly register credits after the log request has
completed, leading to a potential system hang.
BIOSes are supposed to disable L2B micellaneous clock gating by setting
L2_L2B_CK_GATE_CONTROL[CKGateL2BMiscDisable](D0F2xF4_x90[2]) = 1b. This
patch corrects that for those which do not enable this workaround.

dm9620 is a newer variant of dm9601 with more features (usb 2.0, checksum
offload, ..), but it can also be put in a dm9601 compatible mode, allowing
us to reuse the existing driver.
This does mean that the extended features like checksum offload cannot be
used, but that's hardly critical on a 100mbps interface.

Like several other PHY devices which support RGMII, the IC+1001 allows
additional delays to by added to the RX_CLK and TX_CLK signals to
compensate for skew between the clock and data signals. Previously this
was always enabled, but this change makes use of the different RGMII
interface modes to allow the user to specify whether this should be
enabled.

Due to IP_GRE GSO support, GRE can recieve non linear skb which
results in panic in case of GRE_CSUM. Following patch fixes it by

We have historically hard-coded entry points in head.S just so it's easy
to build the executable/bzImage headers with references to them.
Unfortunately, this leads to boot loaders abusing these "known" addresses
even when they are *explicitly* told that they "should look at the ELF
header to find this address, as it may change in the future". And even
when the address in question *has* actually been changed in the past,
without fanfare or thought to compatibility.
Thus we have bootloaders doing stunningly broken things like jumping
to offset 0x200 in the kernel startup code in 64-bit mode, *hoping*
that startup_64 is still there (it has moved at least once
before). And hoping that it's actually a 64-bit kernel despite the
fact that we don't give them any indication of that fact.
This patch should hopefully remove the temptation to abuse internal
addresses in future, where sternly worded comments have not sufficed.
Instead of having hard-coded addresses and saying "please don't abuse
these", we actually pull the addresses out of the ELF payload into
zoffset.h, and make build.c shove them back into the right places in
the bzImage header.
Rather than including zoffset.h into build.c and thus having to rebuild
the tool for every kernel build, we parse it instead. The parsing code
is small and simple.
This patch doesn't actually move any of the interesting entry points, so
any offending bootloader will still continue to "work" after this patch
is applied. For some version of "work" which includes jumping into the
compressed payload and crashing, if the bzImage it's given is a 32-bit
kernel. No change there then.
[ hpa: some of the issues in the description are addressed or
retconned by the 2.12 boot protocol. This patch has been edited to
only remove fixed addresses that were *not* thus retconned. ]

The 'Attributes' argument to pci->Attributes() function is 64-bit. So
when invoking in 32-bit mode it takes two registers, not just one.
This fixes memory corruption when booting via the 32-bit EFI boot stub.

If the bootloader calls the EFI handover entry point as a standard function
call, then it'll have a return address on the stack. We need to pop that
before calling efi_main(), or the arguments will all be out of position on
the stack.

When booting under OVMF we have precisely one GOP device, and it
implements the ConOut protocol.
We break out of the loop when we look at it... and then promptly abort
because 'first_gop' never gets set. We should set first_gop *before*
breaking out of the loop. Yes, it doesn't really mean "first" any more,
but that doesn't matter. It's only a flag to indicate that a suitable
GOP was found.
In fact, we'd do just as well to initialise 'width' to zero in this
function, then just check *that* instead of first_gop. But I'll do the
minimal fix for now (and for stable@).

While sctp handling a duplicate COOKIE-ECHO and the action is
'Association restart', sctp_sf_do_dupcook_a() will processing
the unexpected COOKIE-ECHO for peer restart, but it does not set
the association state to SCTP_STATE_ESTABLISHED, so the association
could stuck in SCTP_STATE_SHUTDOWN_PENDING state forever.
This violates the sctp specification:
RFC 4960 5.2.4. Handle a COOKIE ECHO when a TCB Exists
Action
A) In this case, the peer may have restarted. .....
After this, the endpoint shall enter the ESTABLISHED state.
To resolve this problem, adding a SCTP_CMD_NEW_STATE cmd to the
command list before SCTP_CMD_REPLY cmd, this will set the restart
association to SCTP_STATE_ESTABLISHED state properly and also avoid
I-bit being set in the DATA chunk header when COOKIE_ACK is bundled
with DATA chunks.

We did this for IPv4 in b49d3c1e1c "net: ipmr: limit MRT_TABLE
identifiers" but we need to do it for IPv6 as well. On IPv6 the name
is "pim6reg" instead of "pimreg" so there is one less digit allowed.
The strcpy() is in ip6mr_reg_vif().

commit 9992c2e (net: cdc_ncm: workaround for missing CDC Union)
added code to lookup an IAD for the interface we are probing.
This is redundant. The USB core has already done the lookup
and saved the result in the USB interface struct. Use that
instead.

Define the 2.12 bzImage boot protocol: add xloadflags and additional
fields to allow the command line, initramfs and struct boot_params to
live above the 4 GiB mark.
The xloadflags now communicates if this is a 64-bit kernel with the
legacy 64-bit entry point and which of the EFI handover entry points
are supported.
Avoid adding new read flags to loadflags because of claimed
bootloaders testing the whole byte for == 1 to determine bzImageness
at least until the issue can be researched further.
This is based on patches by Yinghai Lu and David Woodhouse.
