ctnetlink uses the aliases that are created by MODULE_ALIAS_NFCT_HELPER
to auto-load the module based on the helper name. Thus, we have to use
RAS, Q.931 and H.245, not H.323.

Extend log message if packets are ignored to include the TCP state, ie.
replace:

by:
[ 3968.070196] nf_ct_tcp: invalid packet ignored in state ESTABLISHED IN= OUT= SRC=...
This information is useful to know in what state we were while ignoring the

Pull networking tree from David Miller:
1) ptp_pch driver build broke during this merge window due to missing
slab.h header, fix from Geery Uytterhoeven.
2) If ipset passes in a bogus hash table size we crash because the size
is not validated properly. Compounding this, gcc-4.7 can miscompile
ipset such that even when the user specifies legitimate parameters
the tool passes in an out-of-range size to the kernel.
Fix from Jozsef Kadlecsik.
3) Users have reported that the netdev watchdog can trigger with pch_gbe
devices, and it turns out this is happening because of races in the
TX path of the driver leading to the transmitter hanging. Fix from
Eric Dumazet, reported and tested by Andy Cress.
4) Novatel USB551L devices match the generic class entries for the cdc
ethernet USB driver, but they don't work because they have generic
descriptors and thus need FLAG_WWAN to function properly.
Add the necessary ID table entry to fix this, from Dan Williams.
5) A recursive locking fix in the USBNET driver added a new problem, in
that packet list traversal is now racy and we can thus access
unlinked SKBs and crash.
Avoid this situation by adding some extra state tracking, from Ming
Lei.
6) The rtlwifi conversion to asynchronous firmware loading is racy, fix
by reordering the probe procedure. From Larry Finger.
Fixes: https://bugzilla.kernel.org/show_bug.cgi?id=43187
7) Fix regressions with bluetooth keyboards by notifying userland
properly when the security level changes, from Gustavo Padovan.
8) Bluetooth needs to make sure device connected events are emitted
before other kinds of events, otherwise userspace will think there is
no baseband link yet and therefore abort the sockets associated with
that connection.

First, we were at risk of handling thread-info flags, in particular
do_signal(), when returning from kernel space. This could happen
after a failed kernel_execve(), or when forking a kernel thread.
The fix is to test in do_work_pending() for user_mode() and return
immediately if so; we already had this test for one of the flags,
so I just hoisted it to the top of the function.
Second, if a ptraced process updated the callee-saved registers
in the ptregs struct and then processed another thread-info flag, we
would overwrite the modifications with the original callee-saved
registers. To fix this, we add a register to note if we've already
saved the registers once, and skip doing it on additional passes
through the loop. To avoid a performance hit from the couple of
extra instructions involved, I modified the GET_THREAD_INFO() macro
to be guaranteed to be one instruction, then bundled it with adjacent
instructions, yielding an overall net savings.

The qeth layer3 driver is notified about IP address changes.
Changes concerning qeth driven network interfaces have to be
forwarded to the OSA-card. This includes IP addresses of VLAN
interfaces with a qeth device as base device. Function
qeth_l3_verify_vlan_dev() determines if the net_device of the
IP event belongs to a vlan device belonging to a qeth device
as real device. This function is broken starting with commit
7ff0bcf676f7ed224ce21b58c7858c8e527068b2 , which means IP
addresses of VLAN devices are no longer set at the base qeth
device. The patch repairs function qeth_l3_verify_vlan_dev().

codel_should_drop() logic allows a packet being not dropped if queue
size is under max packet size.
In fq_codel, we have two possible backlogs : The qdisc global one, and
the flow local one.
The meaningful one for codel_should_drop() should be the global backlog,
not the per flow one, so that thin flows can have a non zero drop/mark
probability.

The IEEE 802.15.4 Working Group focuses on the standardization of the
bottom two layers of ISO/OSI protocol stack: Physical (PHY) and MAC.
The MAC layer provides access control to a shared channel and reliable
data delivery. The main functions performed by the MAC sublayer are:
association and disassociation, security control, optional star
network topology functions, such as beacon generation and Guaranteed
Time Slots (GTSs) management, generation of ACK frames (if used), and,
finally, application support for the two possible network topologies
described in the standard.
This is an initial commit which describes main data structures needed
for ieee802.15.4 compatible devices representation in the MAC layer.

When handling the H_BULK_REMOVE hypercall, we were forgetting to
invalidate and unlock the hashed page table entry (HPTE) in the case
where the page had been paged out. This fixes it by clearing the
first doubleword of the HPTE in that case.
This fixes a regression introduced in commit a92bce95f0 ("KVM: PPC:
Book3S HV: Keep HPTE locked when invalidating"). The effect of the
regression is that the host kernel will sometimes hang when under

When jumping back into the kernel to code that knows that it would be
using HSRR registers instead of SRR registers, we need to make sure we
pass it all information on where to jump to in HSRR registers.
Unfortunately, we used r10 to store the information to distinguish between
the HSRR and SRR case. That register got clobbered in between though,
rendering the later comparison invalid.
Instead, let's use cr1 to store this information. That way we don't
need yet another register and everyone's happy.
This fixes PR KVM on POWER7 bare metal for me.

When running on a system that is HV capable, some interrupts use HSRR
SPRs instead of the normal SRR SPRs. These are also used in the Linux
handlers to jump back to code after an interrupt got processed.
Unfortunately, in our "jump back to the real host handler after we've
done the context switch" code, we were only setting the SRR SPRs,
rendering Linux to jump back to some invalid IP after it's processed
the interrupt.
This fixes random crashes on p7 opal mode with PR KVM for me.

In addition to normal "priviledged instruction" traps, we can also receive
"emulation assist" traps on newer hardware that has the HV bit set.
Handle that one the same way as a privileged instruction, including the
instruction fetching. That way we don't execute old instructions that we
happen to still leave in that field when an emul assist trap comes.
