Commit d0418bb7123f44b23d69ac349eec7daf9103472f (net: sh_eth: Add eth support
for R8A7779 device) was a failed attempt to add support for one of members of
the R-Car SoC family. That's for three reasons: it treated R8A7779 the same
as SH7724 except including quite dirty hack adding ECMR_ELB bit to the mask
in sh_eth_set_rate() while not removing ECMR_RTM bit (despite it's reserved in
R-Car Ether), and it didn't add a new register offset array despite the closest
SH_ETH_REG_FAST_SH4 mapping differs by 0x200 to the offsets all the R-Car Ether
registers have, and also some of the registers in this old mapping don't exist
on R-Car Ether (due to this, SH7724's 'sh_eth_my_cpu_data' structure is not
adequeate for R-Car too). Fix all these shortcomings, restoring the SH7724
related section to its pristine state...

Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for
an 802.3 frame. Frames with a lower value in the ethernet type field
are Ethernet II.
Also update all the users of this value that David Miller and
I could find to use the new constant.
Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN
should be >= not >.
As suggested by Jesse Gross.
Compile tested only.

The commit 40893fd(net: switch to use skb_probe_transport_header())
involes a new error accidently. When NET_SKBUFF_DATA_USES_OFFSE is
not enabled, below compile error happens:
CC net/packet/af_packet.o
net/packet/af_packet.c: In function ‘packet_sendmsg_spkt’:
net/packet/af_packet.c:1516:2: error: implicit declaration of function ‘skb_probe_transport_header’ [-Werror=implicit-function-declaration]
cc1: some warnings being treated as errors
make[2]: *** [net/packet/af_packet.o] Error 1
make[1]: *** [net/packet] Error 2
make: *** [net] Error 2
As it seems skb_probe_transport_header() is not related to
NET_SKBUFF_DATA_USES_OFFSE, we should move the definition of
skb_probe_transport_header() out of scope of
NET_SKBUFF_DATA_USES_OFFSE macro.

Pull networking fixes from David Miller:
1) Always increment IPV4 ID field in encapsulated GSO packets, even
when DF is set. Regression fix from Pravin B Shelar.
2) Fix per-net subsystem initialization in netfilter conntrack,
otherwise we may access dynamically allocated memory before it is
actually allocated. From Gao Feng.
3) Fix DMA buffer lengths in iwl3945 driver, from Stanislaw Gruszka.
4) Fix race between submission of sync vs async commands in mwifiex
driver, from Amitkumar Karwar.
5) Add missing cancel of command timer in mwifiex driver, from Bing
Zhao.
6) Missing SKB free in rtlwifi USB driver, from Jussi Kivilinna.
7) Thermal layer tries to use a genetlink multicast string that is
longer than the 16 character limit. Fix it and add a BUG check to
prevent this kind of thing from happening in the future.
From Masatake YAMATO.
8) Fix many bugs in the handling of the teardown of L2TP connections,
UDP encapsulation instances, and sockets. From Tom Parkin.
9) Missing socket release in IRDA, from Kees Cook.

driver, from Moshe Lazer, Hadar Hen Zion, and Or Gerlitz.
13) Some FOO_DIAG_MAX constants were defined off by one, fix from Andrey
Vagin.
14) TCP segmentation deferral is unintentionally done too strongly,
breaking ACK clocking. Fix from Eric Dumazet.
15) net_enable_timestamp() can legitimately be invoked from software
interrupts, and in a way that is safe, so remove the WARN_ON().
Also from Eric Dumazet.
16) Fix use after free in VLANs, from Cong Wang.
17) Fix TCP slow start retransmit storms after SACK reneging, from
Yuchung Cheng.
18) Unix socket release should mark a socket dead before NULL'ing out
sock->sk, otherwise we can race. Fix from Paul Moore.
19) IPV6 addrconf code can try to free static memory, from Hong Zhiguo.
20) Fix register mis-programming, NULL pointer derefs, and wrong PHC
clock frequency in IGB driver. From Lior LevyAlex Williamson, Jiri
Benc, and Jeff Kirsher.
21) skb->ip_summed logic in pch_gbe driver is reversed, breaking packet
forwarding. Fix from Veaceslav Falico.

ip-header id needs to be incremented even if IP_DF flag is set.
This behaviour was changed in commit 490ab08127cebc25e3a26
(IP_GRE: Fix IP-Identification).
Following patch fixes it so that identification is always
incremented.

The issue fixed by this patch manifests only then using X11
with mxsfb driver. The X11 will display either shifted image
or otherwise distorted image on the LCD.
The problem is that the X11 tries to reconfigure the framebuffer
and along the way calls fb_ops.fb_set_par() with X11's desired
configuration values. The field of particular interest is
fb_info->var.sync which contains non-standard values if
configured by kernel. These are either FB_SYNC_DATA_ENABLE_HIGH_ACT,
FB_SYNC_DOTCLK_FAILING_ACT or both, depending on the platform
configuration. Both of these values are defined in the
include/linux/mxsfb.h file.
The driver interprets these values and configures the LCD controller
accordingly. Yet X11 only has access to the standard values for this
field defined in include/uapi/linux/fb.h and thus, unlike kernel,
omits these special values. This results in distorted image on the
LCD.
This patch moves these non-standard values into new field of the
mxsfb_platform_data structure so the driver can in turn check this
field instead of the video mode field for these specific portions.
Moreover, this patch prefixes these values with MXSFB_SYNC_ prefix
instead of FB_SYNC_ prefix to prevent confusion of subsequent users.

Booting with 32 TBytes memory hits BUG at mm/page_alloc.c:552! (output
below).
The key hint is "page 4294967296 outside zone".
4294967296 = 0x100000000 (bit 32 is set).
The problem is in include/linux/mmzone.h:
530 static inline unsigned zone_end_pfn(const struct zone *zone)
531 {
532 return zone->zone_start_pfn + zone->spanned_pages;
533 }
zone_end_pfn is "unsigned" (32 bits). Changing it to "unsigned long"
(64 bits) fixes the problem.
zone_end_pfn() was added recently in commit 108bcc96ef70 ("mm: add & use
zone_end_pfn() and zone_spans_pfn()")
Output from the failure.
No AGP bridge found

wake_up_klogd() is useless when CONFIG_PRINTK=n because neither printk()
nor printk_sched() are in use and there are actually no waiter on
log_wait waitqueue. It should be a stub in this case for users like
bust_spinlocks().
Otherwise this results in this warning when CONFIG_PRINTK=n and
CONFIG_IRQ_WORK=n:
kernel/built-in.o In function `wake_up_klogd':
(.text.wake_up_klogd+0xb4): undefined reference to `irq_work_queue'
To fix this, provide an off-case for wake_up_klogd() when
CONFIG_PRINTK=n.
There is much more from console_unlock() and other console related code
in printk.c that should be moved under CONFIG_PRINTK. But for now,
focus on a minimal fix as we passed the merged window already.

Add modem-status-change wait queue to struct usb_serial_port that
subdrivers can use to implement TIOCMIWAIT.
Currently subdrivers use a private wait queue which may have been
released when waking up after device disconnected.
Note that we're adding a new wait queue rather than reusing the tty-port
one as we do not want to get woken up at hangup (yet).

usb: fixes for v3.9-rc4
udc-core learned that it shouldn't use invalid pointers
when unloading a gadget driver.
net2272 and net2280 got a fix for a regression caused by
the udc_start/udc_stop conversion.
We're defining a static inline no-op for otg_ulpi_create()
to prevent build errors when that driver isn't enabled.
FunctionFS got a fix for an off-by-one error when binding
and unbinding instances of FunctionFS.
MUSB learned that it shouldn't try to unmap buffers which
weren't previously mapped.
f_rndis got a fix for a possible NULL pointer dereference
in a debugging message code.
MUSB's DA8xx glue layer got a build fix due to a typo.

Both mci.mem_is_per_rank and mci.csbased denote the same thing: the
memory controller is csrows based. Merge both fields into one.
There's no need for the driver to actually fill it, as the core detects
it by checking if one of the layers has the csrows type as part of the
memory hierarchy:
if (layers[i].type == EDAC_MC_LAYER_CHIP_SELECT)
per_rank = true;

Because hash_64() is called from the get_kprobe() inside
int3 handler, kernel causes int3 recursion and crashes if
kprobes user puts a probe on it.
Usually hash_64() is inlined into caller function, but in
some cases, it has instances by gcc's interprocedural
constant propagation.
This patch uses __always_inline instead of inline to
prevent gcc from doing such things.

be included/compiled even when KVM is not enabled.

Sometimes, we need probe and set the transport header for packets (e.g from
untrusted source). This patch introduces a new helper
skb_probe_transport_header() which tries to probe and set the l4 header through
skb_flow_dissect(), if not just set the transport header to the hint passed by
caller.

packet inspection.
Inspection of upper layer protocol is considered harmful, especially
if it is about ARP or other stateful upper layer protocol; driver
cannot (and should not) have full state of them.
IPv4 over Firewire module used to inspect ARP (both in sending path
and in receiving path), and record peer's GUID, max packet size, max
speed and fifo address. This patch removes such inspection by extending
our "hardware address" definition to include other information as well:
max packet size, max speed and fifo. By doing this, The neighbour
module in networking subsystem can cache them.
Note: As we have started ignoring sspd and max_rec in ARP/NDP, those
information will not be used in the driver when sending.
When a packet is being sent, the IP layer fills our pseudo header with
the extended "hardware address", including GUID and fifo. The driver
can look-up node-id (the real but rather volatile low-level address)
by GUID, and then the module can send the packet to the wire using
parameters provided in the extendedn hardware address.
This approach is realistic because IP over IEEE1394 (RFC2734) and IPv6
over IEEE1394 (RFC3146) share same "hardware address" format
in their address resolution protocols.
Here, extended "hardware address" is defined as follows:
union fwnet_hwaddr {
u8 u[16];
struct {
__be64 uniq_id; /* EUI-64 */
u8 max_rec; /* max packet size */
u8 sspd; /* max speed */
__be16 fifo_hi; /* hi 16bits of FIFO addr */
__be32 fifo_lo; /* lo 32bits of FIFO addr */
} __packed uc;
};
Note that Hardware address is declared as union, so that we can map full
IP address into this, when implementing MCAP (Multicast Cannel Allocation
Protocol) for IPv6, but IP and ARP subsystem do not need to know this
format in detail.
One difference between original ARP (RFC826) and 1394 ARP (RFC2734)
is that 1394 ARP Request/Reply do not contain the target hardware address
field (aka ar$tha). This difference is handled in the ARP subsystem.

Following patch refactors GRE code into ip tunneling code and GRE
specific code. Common tunneling code is moved to ip_tunnel module.
ip_tunnel module is written as generic library which can be used
by different tunneling implementations.
ip_tunnel module contains following components:
- packet xmit and rcv generic code. xmit flow looks like
(gre_xmit/ipip_xmit)->ip_tunnel_xmit->ip_local_out.
- hash table of all devices.
- lookup for tunnel devices.
- control plane operations like device create, destroy, ioctl, netlink
operations code.
- registration for tunneling modules, like gre, ipip etc.
- define single pcpu_tstats dev->tstats.
- struct tnl_ptk_info added to pass parsed tunnel packet parameters.
ipip.h header is renamed to ip_tunnel.h

ip-header id needs to be incremented even if IP_DF flag is set.
This behaviour was changed in commit 490ab08127cebc25e3a26
(IP_GRE: Fix IP-Identification).
Following patch fixes it so that identification is always
incremented.

The patch introduces nf_conntrack_cleanup_net_list(), which cleanups
nf_conntrack for a list of netns and calls synchronize_net() only once
for them all. This should reduce netns destruction time.
I've measured cleanup time for 1k dummy net ns. Here are the results:
<without the patch>
# modprobe nf_conntrack
# time modprobe -r nf_conntrack
real 0m10.337s
user 0m0.000s
sys 0m0.376s
<with the patch>
# modprobe nf_conntrack
# time modprobe -r nf_conntrack

After patch 1 got accepted to net-next I will also send a patch to
netfilter-devel to make the corresponding changes to the netfilter
reassembly logic.
Thanks,

This patch adds a dev_addr_genid for IPv6. The goal is to use it, combined with
dev_base_seq to check if a change occurs during a netlink dump.
If a change is detected, the flag NLM_F_DUMP_INTR is set in the first message
after the dump was interrupted.
Note that only dump of unicast addresses is checked (multicast and anycast are
not checked).

With decnet converted, we can finally get rid of rta_buf and its
computations around it. It also gets rid of the minimal header
length verification since all message handlers do that explicitly
anyway.

decnet is the only subsystem left that is relying on the global
netlink attribute buffer rta_buf. It's horrible design and we
want to get rid of it.
This converts all of decnet to do implicit attribute parsing. It
also gets rid of the error prone struct dn_kern_rta.
Yes, the fib_magic() stuff is not pretty.
It's compiled tested but I need someone with appropriate hardware
to test the patch since I don't have access to it.

This patch converts the Marvell MV643XX ethernet driver to use the
Marvell Orion MDIO driver. As a result, PowerPC and ARM platforms
registering the Marvell MV643XX ethernet driver are also updated to
register a Marvell Orion MDIO driver. This driver voluntarily overlaps
with the Marvell Ethernet shared registers because it will use a subset
of this shared register (shared_base + 0x4 to shared_base + 0x84). The
Ethernet driver is also updated to look up for a PHY device using the
Orion MDIO bus driver.
For ARM and PowerPC we register a single instance of the "mvmdio" driver
in the system like it used to be done with the use of the "shared_smi"
platform_data cookie on ARM.
Note that it is safe to register the mvmdio driver only for the "ge00"
instance of the driver because this "ge00" interface is guaranteed to
always be explicitely registered by consumers of
arch/arm/plat-orion/common.c and other instances (ge01, ge10 and ge11)
were all pointing their shared_smi to ge00. For PowerPC the in-tree
Device Tree Source files mention only one MV643XX ethernet MAC instance
so the MDIO bus driver is registered only when id == 0.
