Commit 70be6c91c86596ad2b60c73587880b47df170a41
("xfrm: Add xfrm_tunnel_skb_cb to the skb common buffer") added check
which dereferences ->outer_mode too early but larval SAs don't have
this pointer set (yet). So check for tunnel stuff later.
Mike Noordermeer reported this bug and patiently applied all the debugging.
Technically this is remote-oops-in-interrupt-context type of thing.
1) In TCP, don't register an FRTO for cumulatively ACK'd data that was
previously SACK'd, from Neal Cardwell.
2) Need to hold RNL mutex in ipv4 multicast code namespace cleanup,
from Cong WANG.
3) Similarly we have to hold RNL mutex for fib_rules_unregister(), also
from Cong WANG.
4) Revert and rework netns nsid allocation fix, from Nicolas Dichtel.
5) When we encapsulate for a tunnel device, skb->sk still points to the
user socket. So this leads to cases where we retraverse the
ipv4/ipv6 output path with skb->sk being of some other address
family (f.e. AF_PACKET). This can cause things to crash since the
ipv4 output path is dereferencing an AF_PACKET socket as if it were
an ipv4 one.
The short term fix for 'net' and -stable is to elide these socket
checks once we've entered an encapsulation sequence by testing
xmit_recursion.
Longer term we have a better solution wherein we pass the tunnel's
socket down through the output paths, but that is way too invasive
for 'net' and -stable.
From Hannes Frederic Sowa.
6) l2tp_init() failure path forgets to unregister per-net ops, from
Cong WANG.

net: dsa: fix filling routing table from OF description
According to description in 'include/net/dsa.h', in cascade switches
configurations where there are more than one interconnected devices,
'rtable' array in 'dsa_chip_data' structure is used to indicate which
port on this switch should be used to send packets to that are destined
for corresponding switch.
However, dsa_of_setup_routing_table() fills 'rtable' with port numbers
of the _target_ switch, but not current one.
This commit removes redundant devicetree parsing and adds needed port
number as a function argument. So dsa_of_setup_routing_table() now just
looks for target switch number by parsing parent of 'link' device node.
To remove possible misunderstandings with the way of determining target
switch number, a corresponding comment was added to the source code and
to the DSA device tree bindings documentation file.
This was tested on a custom board with two Marvell 88E6095 switches with
following corresponding routing tables: { -1, 10 } and { 8, -1 }.

We should not consult skb->sk for output decisions in xmit recursion

ipv6 does not conform with this in three places:
1) ip6_fragment: we do consult ipv6_npinfo for frag_size
2) sk_mc_loop in ipv6 uses skb->sk and checks if we should
loop the packet back to the local socket
3) ip6_skb_dst_mtu could query the settings from the user socket and
force a wrong MTU
Furthermore:
In sk_mc_loop we could potentially land in WARN_ON(1) if we use a
PF_PACKET socket ontop of an IPv6-backed vxlan device.

netns: don't allocate an id for dead netns
First, let's explain the problem.
Suppose you have an ipip interface that stands in the netns foo and its link
part in the netns bar (so the netns bar has an nsid into the netns foo).
Now, you remove the netns bar:
- the bar nsid into the netns foo is removed
- the netns exit method of ipip is called, thus our ipip iface is removed:
=> a netlink message is built in the netns foo to advertise this deletion
=> this netlink message requests an nsid for bar, thus a new nsid is
allocated for bar and never removed.
This patch adds a check in peernet2id() so that an id cannot be allocated for
a netns which is currently destroyed.

The FRTO code should only consider a cumulative ACK to indicate that

xen-netfront: transmit fully GSO-sized packets
xen-netfront limits transmitted skbs to be at most 44 segments in size. However,
GSO permits up to 65536 bytes, which means a maximum of 45 segments of 1448
bytes each. This slight reduction in the size of packets means a slight loss in
efficiency.
Since c/s 9ecd1a75d, xen-netfront sets gso_max_size to
XEN_NETIF_MAX_TX_SIZE - MAX_TCP_HEADER,
where XEN_NETIF_MAX_TX_SIZE is 65535 bytes.
The calculation used by tcp_tso_autosize (and also tcp_xmit_size_goal since c/s 6c09fa09d) in determining when to split an skb into two is
sk->sk_gso_max_size - 1 - MAX_TCP_HEADER.
So the maximum permitted size of an skb is calculated to be
(XEN_NETIF_MAX_TX_SIZE - MAX_TCP_HEADER) - 1 - MAX_TCP_HEADER.
Intuitively, this looks like the wrong formula -- we don't need two TCP headers.
Instead, there is no need to deviate from the default gso_max_size of 65536 as
this already accommodates the size of the header.
Currently, the largest skb transmitted by netfront is 63712 bytes (44 segments
of 1448 bytes each), as observed via tcpdump. This patch makes netfront send
skbs of up to 65160 bytes (45 segments of 1448 bytes each).
Similarly, the maximum allowable mtu does not need to subtract MAX_TCP_HEADER as
it relates to the size of the whole packet, including the header.

x86/asm/entry/64: Disable opportunistic SYSRET if regs->flags has TF set
When I wrote the opportunistic SYSRET code, I missed an important difference
between SYSRET and IRET.
Both instructions are capable of setting EFLAGS.TF, but they behave differently
when doing so:
- IRET will not issue a #DB trap after execution when it sets TF.
This is critical -- otherwise you'd never be able to make forward progress when
returning to userspace.
- SYSRET, on the other hand, will trap with #DB immediately after
returning to CPL3, and the next instruction will never execute.
This breaks anything that opportunistically SYSRETs to a user
context with TF set. For example, running this code with TF set

When running in a kdump kernel, it's very likely that due to sync. loss with
management firmware the first PCI function to probe and reach the previous
unload flow would decide it can reset the chip and continue onward. While doing
so, it will only close its own Rx port.
On a 4-port device where 2nd port on engine is a 1g-port, the 2nd port would
allow ingress traffic after the chip is reset [assuming it was active on the
first kernel]. This would later cause a HW attention.
This changes driver flow to close both ports' 1g capabilities during the
previous driver unload flow prior to the chip reset.

There's an issue with the way the RX A-MPDU reorder timer is
deleted that can cause a kernel crash like this:
* tid_rx is removed - call_rcu(ieee80211_free_tid_rx)
* station is destroyed
* reorder timer fires before ieee80211_free_tid_rx() runs,
accessing the station, thus potentially crashing due to
the use-after-free
The station deletion is protected by synchronize_net(), but
that isn't enough -- ieee80211_free_tid_rx() need not have
run when that returns (it deletes the timer.) We could use
rcu_barrier() instead of synchronize_net(), but that's much
more expensive.
Instead, to fix this, add a field tracking that the session
is being deleted. In this case, the only re-arming of the
timer happens with the reorder spinlock held, so make that
code not rearm it if the session is being deleted and also
delete the timer after setting that field. This ensures the
timer cannot fire after ___ieee80211_stop_rx_ba_session()
returns, which fixes the problem.

The ASRock Q1900DC-ITX mainboard (Baytrail-D) hangs randomly in
both BIOS and UEFI mode while rebooting unless reboot=pci is
used. Add a quirk to reboot via the pci method.
The problem is very intermittent and hard to debug, it might succeed
rebooting just fine 40 times in a row - but fails half a dozen times
the next day. It seems to be slightly less common in BIOS CSM mode
than native UEFI (with the CSM disabled), but it does happen in either
mode. Since I've started testing this patch in late january, rebooting
has been 100% reliable.
Most of the time it already hangs during POST, but occasionally it
might even make it through the bootloader and the kernel might even
start booting, but then hangs before the mode switch. The same symptoms
occur with grub-efi, gummiboot and grub-pc, just as well as (at least)
kernel 3.16-3.19 and 4.0-rc6 (I haven't tried older kernels than 3.16).
Upgrading to the most current mainboard firmware of the ASRock
Q1900DC-ITX, version 1.20, does not improve the situation.
( Searching the web seems to suggest that other Bay Trail-D mainboards
might be affected as well. )

We currently have a problem that SELinux policy is being enforced when

This seems wrong. We don't do that for files under /proc, for instance,

While discussing that patch however, Greg K.H. stated:
"No kernel code should care / fail if a debugfs function fails, so
please fix up the sunrpc code first."
This patch converts all of the sunrpc debugfs setup code to be void
return functins, and the callers to not look for errors from those
