Pull networking fixes from David Miller:
1) Found via trinity:
If you connect up an ipv6 socket to an ipv4 mapped address then an
ipv6 one, sendmsg() can croak because ip6_sk_dst_check() assumes the
route cached in the socket is an ipv6 one. In this case there is an
ipv4 route attached, so it gets stomped on.
Reported by Dave Jones and Hannes Frederic Sowa, fixed by Eric
Dumazet.
2) AF_KEY notifications leak some kernel memory to userspace, fix from
Mathias Krause.
3) DLCI calls __dev_get_by_name() without proper locking, and dlci_del
doesn't validate that the device being deleted is actually a DLCI
one. Fixes from Li Zefan.
4) Length check on bluetooth l2cap information responses is wrong, each
response type has a different lenth, so we should make sure it's in
a given range rather than enforce one single valid length. From
Jaganath Kanakkassery.
5) Receive FIFO overflow is really easy to trigger in stress scenerios
in the sh_eth driver, but the event isn't being handled properly at
all. Specifically, the mask of error interrupts doesn't include the
event so we never clear it, resulting in the driver becomming wedged
processing an interrupt that never gets cleared.
Fix from Sergei Shtylyov.
6) qlcnic sleeps while holding a spinlock, use mdelay() instead of
msleep(). From Shahed Shaikh.
7) Missing curly braces causes SIP netfilter NAT module to always drop
packets. Fix from Balazs Peter Odor.
8) ipt_ULOG in netfilter passes the wrong value to timer setup, causing
the timer to dereference crap when it fires. Fix from Gao Feng.
9) Missing RCU protection around txq->axq_acq traversal in
ath_txq_schedule(). Fix from Felix Fietkau.
10) Idle state transition test in ath9k_htc_config() is reversed, fix
from Sujith Manoharan.
11) IPV6 forwarding handles unicast Router Alert packets incorrectly.
It tests the wrong option state. Previously opt->ra being non-zero
indicated a router alert marking in the SKB, but now it's indicated
by a bit in opt->flags. Fix from YOSHIFUJI Hideaki.
12) SKB leak in GRE tunnel GSO handling, from Eric Dumazet.
13) get_user_pages_fast() error handling in TUN and MACVTAP use the same
local variable for the base index and the loop iterator for page
traversal, oops! Fix from Michael S Tsirkin.
14) ipv6_get_lladdr() can fail, and we must therefore check it's return
value in inet6_set_iftoken(). For from Hannes Frederic Sowa.
15) If you change an interface name and meanwhile can sneak in something
that looks up the name (like SO_BINDTODEVICE or SIOCGIFNAME) we can
deadlock with CONFIG_PREEMPT=n. Fix this by providing a helper
function that properly uses raw_seqcount_begin(). From Nicolas
Schichan.
16) Chain noise calibration test is inverted in iwlwifi, fix from
Nikolay Martynov.
17) Properly set TX iwlwifi descriptor flags for back requests. Fix
from Emmanuel Grumbach.
18) We can't assume skb_transport_header() is set in xt_TCPOPTSTRAP
module, fix from Pablo Neira Ayuso.
19) Some crummy APs don't provide the proper High Throughput info in
association response frames. Add a workaround by assume we'll use
whatever is in the beacon/probe. Fix from Johannes Berg.
20) mac80211 call to rate_idx_match_mask() swaps two arguments (mask and
channel width). Fix from Simon Wunderlich.
21) xt_TCPMSS (like xt_TCPOPTSTRAP) must not try to handle fragmented
frames. Fix from Phil Oester.
22) Fix rate control regression causing iwlwifi/iwlegacy chips to use
1Mbit/s on pre-11n networks. From Moshe Benji and Stanslaw Gruszka.
23) Disable brcmsmac power-save functions, they cause regressions. From
Arend van Spriel.
24) Enforce a sane minimum MTU in l2cap_build_cmd() otherwise we can
easily crash. Fix from Anderson Lizardo.
25) If a learning packet arrives during vxlan_stop() we crash, easily
fixed by checking netif_running(). From Stephen Hemminger.
26) Static vxlan FDB entries should not be migrated, also from Stephen.
27) skb_clone() failures not handled in vxlan_xmit(), oops. Also from
Stephen.
28) Add minimal driver for AR816x/AR817x ethernet chips, from Johannes
Berg.
29) Fix regression in userspace VLAN acceleration control, added by the
802.1ad support changes. Fix from Fernando Luis Vazquez Cao.
30) Interval selection for MLD queries in the bridging code was
reversed. Fix from Linus Lüssing.
31) ipv6's ndisc_send_redirect() erroneously writes to the packet we
received not the packet we are building to send out. Fix from
Matthias Schiffer.
32) Don't free netdev before unregistering it, in usb_8dev can driver.
From Marc Kleine-Budde.
33) Fix nl80211 attribute buffer races, from Johannes Berg.
34) Although netlink_diag.h is under uapi/ it isn't present in Kbuild.
From Stephen Hemminger.
35) Wrong address and family passed to MD5 key lookups in TCP, from
Aydin Arik.
36) phy_type attribute created by SFC driver should not be writable.
From Ben Hutchings.
37) Receive/Transmit queue allocations in pxa168_eth and mv643xx_eth
should use kzalloc(). Otherwise if setup fails half-way, we'll
dereference garbage when trying to teardown the rings. From Lubomir
Rintel.
38) Fix double-allocation of dst (resulting in unfreeable net device) in
ipv6's init_loopback(). From Gao Feng.
39) Fix fragmentation handling SKB leak in netfilter conntrack, we were
freeing the wrong skb pointer. From Phil Oester.
40) Don't report "-1" (SPEED_UNKNOWN) in bond_miimon_commit(), from
Nikolay Aleksandrov.
41) davinci_cpdma doesn't check for DMA mapping errors, letting the
device scribble to random addresses. From Sebastian Siewior.

It's possible to use AF_INET6 sockets and to connect to an IPv4
destination. After this, socket dst cache is a pointer to a rtable,
not rt6_info.
ip6_sk_dst_check() should check the socket dst cache is IPv6, or else
various corruptions/crashes can happen.

When the kernel (compiled with CONFIG_PREEMPT=n) is performing the
rename of a network interface, it can end up waiting for a workqueue
to complete. If userland is able to invoke a SIOCGIFNAME ioctl or a
SO_BINDTODEVICE getsockopt in between, the kernel will deadlock due to
the fact that read_secklock_begin() will spin forever waiting for the
writer process (the one doing the interface rename) to update the
devnet_rename_seq sequence.
This patch fixes the problem by adding a helper (netdev_get_name())
and using it in the code handling the SIOCGIFNAME ioctl and
SO_BINDTODEVICE setsockopt.
The netdev_get_name() helper uses raw_seqcount_begin() to avoid
spinning forever, waiting for devnet_rename_seq->sequence to become
even. cond_resched() is used in the contended case, before retrying
the access to give the writer process a chance to finish.
The use of raw_seqcount_begin() will incur some unneeded work in the
reader process in the contended case, but this is better than
deadlocking the system.

Pull late power management and ACPI fixes from Rafael Wysocki:
"Sorry about the timing of this, but ACPI-based docking stations with
PCI devices on them and ATA bays would be hardly usable with 3.10
without it. We've been working on these fixes for the last couple of
weeks and everyone involved appears to be reasonably comfortable with
them now.
The PM part is one fix for a cpufreq regression introduced recently
- Fix for an ACPI dock regression introduced by the recent rework of
the ACPI-based PCI hotplug code (acpiphp) that caused it to be
initialized before the ACPI dock driver, which is incorrect (ACPI
dock has to be initialized before acpiphp so that acpiphp can
register PCI devices on docking stations with it for PCI hotplug on
re-dock to work). From Jiang Liu.
- Fix for PCI resources allocation in the ACPI-based PCI hotplug code
(acpiphp) that makes it use the same PCI resources assignment rules
during runtime hotplug that are used during boot (the BIOS' choices
are now respected in both cases). This prevents PCI resource
allocation failures during hotplug from happening in some cases.
From Jiang Liu.
- Fix for ordering and synchronization issues during hot-removal of
PCI devices on docking stations. It makes the ACPI dock code carry
out the PCI devices removal synchronously during undock instead of
spawning a separate asynchronous work item to remove each of them
without even bothering to wait for all those work items to
complete. The hot-addition part is changed analogously.
- Fix for a regression (introduced a few releases ago) that removed
the code to register a hotplug notificaion handler for for ATA
ports/devices inadvertently which prevented ATA bays hotplug from
working. The missing code is added back with some improvements.
From Aaron Lu.
- Fix for a recent cpufreq regression causing a NULL pointer
dereference to trigger in od_set_powersave_bias() in some
situations from Jacob Shin"

This change addresses two warnings that are flagged by gcc relating to
potential access to the ssr and cks variables while they are uninitialised.
I have addressed this by initialising the values to
the defaults present in sci_baud_calc_hscif().
It is my analysis that cks is always initialised if used
but that without this change ssr may be accessed while uninitialised.
The code altered by this patch was introduced by commit
f303b364b41d3fc5bf879799128958400b7859aa ("serial: sh-sci: HSCIF support").

Commit ede4d7a5 ("gpio/omap: convert gpio irq domain to linear mapping")
converted the OMAP GPIO driver to use a linear mapping for the GPIO IRQ
domain instead of using a legacy mapping. Not using a legacy mapping has
a number of benefits but it requires the platform to support SPARSE_IRQ
which currently is not supported on OMAP1.
So this change caused a regression on OMAP1 platforms [1].
Since this issue is not present on all OMAP2+ platforms, there is no need to
revert the driver to use legacy domain mapping for all the platforms.

commit 20d49e9ccfece526db755940721aa13e331936d4
(ARM: OMAP5: voltagedomain data: Add OMAP5 voltage domain data)
Introduced dummy volt data for OMAP5 with OMAP4460 voltage information.
However with the fixes introduced in later patches
commit cd8abed1da91a3250aa4b3857479613a2b446f84
(ARM: OMAP2+: Powerdomain: Remove the need to always have a voltdm
associated to a pwrdm)
We are no longer restricted in that respect. Further, OPP voltage
information is supposed to be provided by dts information. This needs
to be added in future patches as various voltage modules are converted
to dts.
This also fixes the build breakage for voltagedomains54xx_data.c when just
OMAP5 SoC is enabled: https://patchwork.kernel.org/patch/2764191/

When the EEH error is the result of a fenced host bridge, MMIO accesses
can be very slow (milliseconds) to timeout and return all 1's,
thus causing the driver various timeout loops to take way too long and
trigger soft-lockup warnings (in addition to taking minutes to recover).
It might be worthwhile to check if for any of these cases, ffffffff is
a valid possible value, and if not, bail early since that means the HW
is either gone or isolated. In the meantime, checking that the PCI channel
is offline would be workaround of the problem.

commit ea1418b5f1a (usb: chipidea: i.MX: use devm_usb_get_phy_by_phandle to get
phy) causes the USB host to miss the disconnect/connect events.
In order to reproduce this problem:
- Insert a USB thumb into the USB host port (connection is detected)
- Remove it (no disconnect event will be reported)
- Insert the USB thumb again (connection is not detected)
Fix this problem by accessing the usb_phy structure using the private data
instead of accessing a local structure.
Tested on a mx28evk board.

We should check the return value of ipv6_get_lladdr in inet6_set_iftoken.
A possible situation, which could leave ll_addr unassigned is, when
the user removed her link-local address but a global scoped address was
already set. In this case the interface would still be IF_READY and not
dead. In that case the RS source address is some value from the stack.
v2: Daniel Borkmann noted a small indent inconstancy; no semantic
changes.

commit 68c331631143 ("v4 GRE: Add TCP segmentation offload for GRE")
added a possible skb leak, because it frees only the head of segment
list, in case a skb_linearize() call fails.
This patch adds a kfree_skb_list() helper to fix the bug.

John W. Linville says:
====================
A few more late-breaking fixes hoping for 3.10...
Regarding the Bluetooth fix, Gustavo says:
"A important fix to 3.10, this patch fixes an issues that was preventing
the l2cap info response command to be handled properly."
Also for that Bluetooth fix, Johan adds:
"Once the code gives up parsing this PDU it also gives up essential
parts of the L2CAP connection creation process, i.e. without this
patch the stack will fail to establish connections properly."
Moving onto ath9k, Felix Fietkau fixes an RCU locking issue in
the transmit path. As for ath9k_htc, Sujith Manoharan fixes some
authentication timeouts by ensuring that a chip reset is done when
IDLE is turned off.
I think these are all micro-fixes that shouldn't cause any trouble.
Please let me know if there are problems!

Router Alert option is marked in skb.
Previously, IP6CB(skb)->ra was set to positive value for such packets.
Since commit dd3332bf ("ipv6: Store Router Alert option in IP6CB
directly."), IP6SKB_ROUTERALERT is set in IP6CB(skb)->flags, and
the value of Router Alert option (in network byte order) is set
to IP6CB(skb)->ra for such packets.
Multicast forwarding path uses that flag and value, but unicast
forwarding path does not use the flag and misuses IP6CB(skb)->ra
value.
