Currently the UFO fragmentation process does not correctly handle inner
UDP frames.

(The following tcpdumps are captured on the parent interface with ufo
disabled while tunnel has ufo enabled, 2000 bytes payload, mtu 1280,
both sit device):

IPv6:
16:39:10.031613 IP (tos 0x0, ttl 64, id 3208, offset 0, flags [DF], proto IPv6 (41), length 1300)
    192.168.122.151 > 1.1.1.1: IP6 (hlim 64, next-header Fragment (44) payload length: 1240) 2001::1 > 2001::8: frag (0x00000001:0|1232) 44883 > distinct: UDP, length 2000
16:39:10.031709 IP (tos 0x0, ttl 64, id 3209, offset 0, flags [DF], proto IPv6 (41), length 844)
    192.168.122.151 > 1.1.1.1: IP6 (hlim 64, next-header Fragment (44) payload length: 784) 2001::1 > 2001::8: frag (0x00000001:0|776) 58979 > 46366: UDP, length 5471

We can see that fragmentation header offset is not correctly updated.
(fragmentation id handling is corrected by 916e4cf4 ("ipv6: reuse
ip6_frag_id from ip6_ufo_append_data")).

IPv4:
16:39:57.737761 IP (tos 0x0, ttl 64, id 3209, offset 0, flags [DF], proto IPIP (4), length 1296)
    192.168.122.151 > 1.1.1.1: IP (tos 0x0, ttl 64, id 57034, offset 0, flags [none], proto UDP (17), length 1276)
    192.168.99.1.35961 > 192.168.99.2.distinct: UDP, length 2000
16:39:57.738028 IP (tos 0x0, ttl 64, id 3210, offset 0, flags [DF], proto IPIP (4), length 792)
    192.168.122.151 > 1.1.1.1: IP (tos 0x0, ttl 64, id 57035, offset 0, flags [none], proto UDP (17), length 772)
    192.168.99.1.13531 > 192.168.99.2.20653: UDP, length 51109

In this case fragmentation id is incremented and offset is not updated.

First, I aligned inet_gso_segment and ipv6_gso_segment:
* align naming of flags
* ipv6_gso_segment: setting skb->encapsulation is unnecessary, as we
  always ensure that the state of this flag is left untouched when
  returning from upper gso segmenation function
* ipv6_gso_segment: move skb_reset_inner_headers below updating the
  fragmentation header data, we don't care for updating fragmentation
  header data
* remove currently unneeded comment indicating skb->encapsulation might
  get changed by upper gso_segment callback (gre and udp-tunnel reset
  encapsulation after segmentation on each fragment)

If we encounter an IPIP or SIT gso skb we now check for the protocol ==
IPPROTO_UDP and that we at least have already traversed another ip(6)
protocol header.

The reason why we have to special case GSO_IPIP and GSO_SIT is that
we reset skb->encapsulation to 0 while skb_mac_gso_segment the inner
protocol of GSO_UDP_TUNNEL or GSO_GRE packets.

tcp_is_cwnd_limited() allows GSO/TSO enabled flows to increase
their cwnd to allow a full size (64KB) TSO packet to be sent.

Non GSO flows only allow an extra room of 3 MSS.

For most flows with a BDP below 10 MSS, this results in a bloat
of cwnd reaching 90, and an inflate of RTT.

Thanks to TSO auto sizing, we can restrict the bloat to the number
of MSS contained in a TSO packet (tp->xmit_size_goal_segs), to keep
original intent without performance impact.

Because we keep cwnd small, it helps to keep TSO packet size to their
optimal value.

Example for a 10Mbit flow, with low TCP Small queue limits (no more than
2 skb in qdisc/device tx ring)

is pretty hairy to identify the correct net namespace and dst there.
Especially tunnels use IFF_XMIT_DST_RELEASE and thus have no skb_dst

This causes unreliable or very predictable ipv6 fragmentation id
generation while segmentation.

Problem statement: 1) both paths (primary path1 and alternate
path2) are up after the association has been established i.e.,
HB packets are normally exchanged, 2) path2 gets inactive after
path_max_retrans * max_rto timed out (i.e. path2 is down completely),
3) now, if a transmission times out on the only surviving/active
path1 (any ~1sec network service impact could cause this like
a channel bonding failover), then the retransmitted packets are
sent over the inactive path2; this happens with partial failover
and without it.

Besides not being optimal in the above scenario, a small failure
or timeout in the only existing path has the potential to cause
long delays in the retransmission (depending on RTO_MAX) until
the still active path is reselected. Further, when the T3-timeout
occurs, we have active_patch == retrans_path, and even though the
timeout occurred on the initial transmission of data, not a
retransmit, we end up updating retransmit path.

RFC4960, section 6.4. "Multi-Homed SCTP Endpoints" states under
6.4.1. "Failover from an Inactive Destination Address" the
following:

  Some of the transport addresses of a multi-homed SCTP endpoint
  may become inactive due to either the occurrence of certain
  error conditions (see Section 8.2) or adjustments from the
  SCTP user.

  When there is outbound data to send and the primary path
  becomes inactive (e.g., due to failures), or where the SCTP
  user explicitly requests to send data to an inactive
  destination transport address, before reporting an error to
  its ULP, the SCTP endpoint should try to send the data to an
  alternate __active__ destination transport address if one
  exists.

  When retransmitting data that timed out, if the endpoint is
  multihomed, it should consider each source-destination address
  pair in its retransmission selection policy. When retransmitting
  timed-out data, the endpoint should attempt to pick the most
  divergent source-destination pair from the original
  source-destination pair to which the packet was transmitted.

  Note: Rules for picking the most divergent source-destination
  pair are an implementation decision and are not specified
  within this document.

So, we should first reconsider to take the current active
retransmission transport if we cannot find an alternative
active one. If all of that fails, we can still round robin
through unkown, partial failover, and inactive ones in the
hope to find something still suitable.

Commit 4141ddc0 ("sctp: retran_path update bug fix") broke
that behaviour by selecting the next inactive transport when
no other active transport was found besides the current assoc's
peer.retran_path. Before commit 4141ddc0, we would have
traversed through the list until we reach our peer.retran_path
again, and in case that is still in state SCTP_ACTIVE, we would
take it and return. Only if that is not the case either, we
take the next inactive transport.

Besides all that, another issue is that transports in state
SCTP_UNKNOWN could be preferred over transports in state
SCTP_ACTIVE in case a SCTP_ACTIVE transport appears after
SCTP_UNKNOWN in the transport list yielding a weaker transport
state to be used in retransmission.

This patch mostly reverts 4141ddc0, but also rewrites
this function to introduce more clarity and strictness into
the code. A strict priority of transport states is enforced
in this patch, hence selection is active > unkown > partial
failover > inactive.

tipc: clean up components initialization code

In this series, we will fix a regression issue involved by commit

Accidentally a side effect is involved by commit 6e967adf(tipc:
relocate common functions from media to bearer). Now tipc stack
handler of receiving packets from netdevices as well as netdevice
notification handler are registered when bearer is enabled rather
than tipc module initialization stage, but the two handlers are
both unregistered in tipc module exit phase. If tipc module is
inserted and then immediately removed, the following warning
message will appear:

"dev_remove_pack: ffffffffa0380940 not found"

This is because in module insertion stage tipc stack packet handler
is not registered at all, but in module exit phase dev_remove_pack()
needs to remove it. Of course, dev_remove_pack() cannot find tipc
protocol handler from the kernel protocol handler list so that the
warning message is printed out.

But if registering the two handlers is adjusted from enabling bearer
phase into inserting module stage, the warning message will be
eliminated. Due to this change, tipc_core_start_net() and
tipc_core_stop_net() can be deleted as well.

When tipc module is inserted, many tipc components are initialized
one by one. During the initialization period, if one of them is
failed, tipc_core_stop() will be called to stop all components
whatever corresponding components are created or not. To avoid to
release uncreated ones, relevant components have to add necessary
enabled flags indicating whether they are created or not.

But in the initialization stage, if one component is unsuccessfully
created, we will just destroy successfully created components before
the failed component instead of all components. All enabled flags
defined in components, in turn, become redundant. Additionally it's
also unnecessary to identify whether table.types is NULL in
tipc_nametbl_stop() because name stable has been definitely created
successfully when tipc_nametbl_stop() is called.

In current implementation it is possible to reach PF state from unconfirmed.
We can interpret sctp-failover-02 in a way that PF state is meant to be reached
only from active state, in the end, this is when entering PF state makes sense.
Here are few quotes from sctp-failover-02, but regardless of these, same
understanding can be reached from whole section 5:

Section 5.1, quickfailover guide:
    "The PF state is an intermediate state between Active and Failed states."

    "Each time the T3-rtx timer expires on an active or idle
    destination, the error counter of that destination address will
    be incremented.  When the value in the error counter exceeds
    PFMR, the endpoint should mark the destination transport address as PF."

There are several concrete reasons for such interpretation. For start, rfc4960
does not take into concern quickfailover algorithm. Therefore, quickfailover
must comply to 4960. Point where this compliance can be argued is following
behavior:
When PF is entered, association overall error counter is incremented for each
missed HB. This is contradictory to rfc4960, as address, while in unconfirmed
state, is subjected to probing, and while it is probed, it should not increment
association overall error counter. This has as a consequence that we might end
up in situation in which we drop association due path failure on unconfirmed
address, in case we have wrong configuration in a way:
Association.Max.Retrans == Path.Max.Retrans.

Another reason is that entering PF from unconfirmed will cause a loss of address
confirmed event when address is once (if) confirmed. This is fine from failover
guide point of view, but it is not consistent with behavior preceding failover
implementation and recommendation from 4960:

replace its own implementation.

However with that change netfront is broken. It sees a lot of checksum
error. That's because its own implementation of checksum function was a
bit hacky (dereferencing skb->data directly) while the new function was
implemented using ip_hdr(). The network header is not reset before skb
is passed to the new function. When the new function tries to do its
job, it's confused and reports error.

The fix is simple, we need to reset network header before passing skb to
checksum function. Netback is not affected as it already does the right
thing.

Pull ARM fixes from Russell King:
 "A range of ARM fixes.  Biggest change is the stage-2 attributes used
  for for hyp mode which were wrong.  I've killed some bits in a couple
  of DT files which turned out not to be required, and a few other
  fixes.

  One fix touches code outside of arch/arm, which is related to sorting
  out the DMA masks correctly.  There is a long standing issue with the
  conversion from PFNs to addresses where people assume that shifting an
  unsigned long left by PAGE_SHIFT results in a correct address.  This
  is not the case with C: the integer promotion happens at assignment
  after evaluation.  This fixes the recently introduced dma_max_pfn()
  function, but there's a number of other places where we try this
  directly on an unsigned long in the mm code"

The PHY library has been subject to some changes, new drivers and DT
interactions over the past few months. Add myself as a maintainer for
the core PHY library parts and drivers. Make sure the PHY library entry
also covers the Device Tree files which have a close interaction with
the MDIO bus, PHY connection and Ethernet PHY mode parsing.

The of_mdiobus_register_phy() is not setting phy->irq thus causing
some drivers to incorrectly assume that the PHY does not have an
IRQ associated with it. Not only do some drivers report no IRQ
they do not install an interrupt handler for the PHY.

Simplify the code setting irq and set the phy->irq at the same
time so that we cover the following issues, which should cover
all the cases the code will find:

- Set phy->irq if node has irq property and mdio->irq is NULL
- Set phy->irq if node has no irq and mdio->irq is not NULL
- Leave phy->irq as PHY_POLL default if none of the above

This fixes the issue:
 net eth0: attached PHY 1 (IRQ -1) to driver Micrel KSZ8041RNLI

to the correct:
 net eth0: attached PHY 1 (IRQ 416) to driver Micrel KSZ8041RNLI

With the introduction of the support for Armada 375 and Armada 38x,
the hidden Kconfig option MACH_ARMADA_370_XP is being renamed to
MACH_MVEBU_V7. Therefore, the dependency that was used for the mvneta
driver can no longer work. This commit replaces this dependency by a
dependency on PLAT_ORION, which is used similarly for the mv643xx_eth
driver.

In addition to this, it takes this opportunity to adjust the
description and help text to indicate that the driver can is also used
for Armada 38x. Note that Armada 375 cannot use this driver as it has
a completely different networking unit, which will require a separate
driver.

Nothing special. The biggest change is adding a couple of command defines and
packing the command data correctly.

====================
Please pull this batch of fixes intended for the 3.14 stream...

For the iwlwifi one, Emmanuel says:

"As explicitly written in the commit message, we prefer to disable Tx
AMPDU on NICs supported by iwldvm. This feature gives a big boost in
Tx performance, but the firmware is buggy and we can't rely on it.
Our hope is that most of the users out there want wifi to surf on
the web which means that they care more for Rx traffic than for Tx.
People who want to enable it can do so with the help of a module
parameter."

On top of that...

Dan Carpenter fixes a typo/thinko in ath5k.

Olivier Langlois fixes a couple of rtlwifi issues, one which leaves
IRQs disabled too long (causing a variety of problems elsewhere),
and one which fixes an incorrect return code when failing to enable
the NIC.

Russell King fixes a NULL pointer dereference in hostap.

Stanislaw Gruszka fixes a DMA coherence issue in the rtl8187 driver.

Please let me know if there are problems!

SCTP's sctp_connectx() abi breaks for 64bit kernels compiled with 32bit
emulation (e.g. ia32 emulation or x86_x32). Due to internal usage of
'struct sctp_getaddrs_old' which includes a struct sockaddr pointer,
sizeof(param) check will always fail in kernel as the structure in
64bit kernel space is 4bytes larger than for user binaries compiled
in 32bit mode. Thus, applications making use of sctp_connectx() won't
be able to run under such circumstances.

Introduce a compat interface in the kernel to deal with such
situations by using a 'struct compat_sctp_getaddrs_old' structure
where user data is copied into it, and then sucessively transformed
into a 'struct sctp_getaddrs_old' structure with the help of
compat_ptr(). That fixes sctp_connectx() abi without any changes
needed in user space, and lets the SCTP test suite pass when compiled
in 32bit and run on 64bit kernels.
