Allowing userptr bo which are basicly a list of page from some vma
(so either anonymous page or file backed page) would lead to serious
corruption of kernel structures and counters (because we overwrite
the page->mapping field when mapping buffer).
This will already block if the buffer was populated before anyone does
try to mmap it because then TTM_PAGE_FLAG_SG would be set in in the
ttm_tt flags. But that flag is check before ttm_tt_populate in the ttm
vm fault handler.
So to be safe just add a check to verify_access() callback.

With the joys of things running concurrently, there's always a chance
that the port we get passed in drm_dp_payload_send_msg() isn't actually
valid anymore. Because of this, we need to make sure we validate the
reference to the port before we use it otherwise we risk running into
various race conditions. For instance, on the Dell MST monitor I have
here for testing, hotplugging it enough times causes us to kernel panic:
[drm:intel_mst_enable_dp] 1
[drm:drm_dp_update_payload_part2] payload 0 1

With commit 8bc2a40730ec ("rtc: ds1307: add support for the
DT property 'wakeup-source'") we lost the ability for rtc irq
functionality for devices that are actually hooked on a real IRQ
line and have capability to wakeup as well. This is not an expected
behavior. So, instead of just not requesting IRQ, skip the IRQ
requirement only if interrupts are not defined for the device.

The function pcibios_add_device() added by commit d0c31e020057
("sparc/PCI: Fix for panic while enabling SR-IOV") initializes
the dev_archdata by doing a memcpy from the PF. This has the
problem that it erroneously copies the OF device without
explicitly refcounting it.
As David Miller pointed out: "Generally speaking we don't
really support hot-plug for OF probed devices, but if we did
all of the device tree pointers have to be refcounted properly."
To fix this error, and also avoid code duplication, this patch
creates a new helper function, pci_init_dev_archdata(), that
initializes the fields in dev_archdata, and can be invoked
by callers after they have taken the needed refcounts

When using masked actions the ipv6_proto field of an action
to set IPv6 fields may be zero rather than the prevailing protocol
which will result in skipping checksum recalculation.
This patch resolves the problem by relying on the protocol
in the flow key rather than that in the set field action.

atl2 includes NETIF_F_SG in hw_features even though it has no support
for non-linear skbs. This bug was originally harmless since the
driver does not claim to implement checksum offload and that used to
be a requirement for SG.
Now that SG and checksum offload are independent features, if you
explicitly enable SG *and* use one of the rare protocols that can use
SG without checkusm offload, this potentially leaks sensitive
information (before you notice that it just isn't working). Therefore
this obscure bug has been designated CVE-2016-2117.

Commit 2a0787051182 ("irqchip/mips-gic: Use gic_vpes instead of
NR_CPUS") & commit 78930f09b940 ("irqchip/mips-gic: Clear percpu_masks
correctly when mapping") both introduce code which accesses gic_vpes
entries in the pcpu_masks array. However, this array has length NR_CPUS.
If NR_CPUS is less than gic_vpes (ie. the kernel supports use of less
CPUs than are present in the system) then we overrun the array, clobber
some other data & generally die pretty promptly.
Most notably this affects uniprocessor kernels running on any multicore
or multithreaded Malta with a GIC (ie. the vast majority of real Malta
boards).
Fix this by only accessing up to min(gic_vpes, NR_CPUS) entries in the
pcpu_masks array, preventing the array overrun.

Currently changing global pause settings is done via SET_PORT
command with input modifier GENERAL. This command is allowed
for each VF since MTU setting is done via the same command.
Change the above to the following scheme: before passing the
request to the FW, the PF will check whether it was issued
by a slave. If yes, don't change global pause and warn,
otherwise change to the requested value and store for

The ks8895 driver is using spi_dev_get() apparently just to take a copy
of the SPI device used to instantiate it but never calls spi_dev_put()
to free it. Since the device is guaranteed to exist between probe() and
remove() there should be no need for the driver to take an extra
reference to it so fix the leak by just using a straight assignment.

When the DaVinci emac driver is removed and re-probed, the actual
pdev->dev.platform_data is populated with an unwanted valid pointer saved by
the previous davinci_emac_of_get_pdata() call, causing a kernel crash when
calling priv->int_disable() in emac_int_disable().

In order to avoid an Unbalanced pm_runtime_enable in the DaVinci
emac driver when the device is removed and re-probed, and a
pm_runtime_disable() call in davinci_emac_remove().
Actually, using unbind/bind on a TI DM8168 SoC gives :
$ echo 4a120000.ethernet > /sys/bus/platform/drivers/davinci_emac/unbind

In firmware assisted GRO flow there could be a single MTU sized
segment arriving due to firmware aggregation timeout/last segment
in an aggregation flow, which is not expected to be an actual gro
packet. So If a skb has zero frags from the GRO flow then simply
push it in the stack as non gso skb.

After receiving sacks, tcp_shifted_skb() will collapse
skbs if possible. tx_flags and tskey also have to be
merged.
This patch reuses the tcp_skb_collapse_tstamp() to handle
them.

If two skbs are merged/collapsed during retransmission, the current
logic does not merge the tx_flags and tskey. The end result is
the SCM_TSTAMP_ACK timestamp could be missing for a packet.
The patch:
1. Merge the tx_flags
2. Overwrite the prev_skb's tskey with the next_skb's tskey

The cpsw_ndo_open() could try to access CPSW registers before
calling pm_runtime_get_sync(). This will trigger L3 error:

44000000.ocp:L3 Custom Error: MASTER M2 (64-bit) TARGET L4_FAST (Idle): Data Access in Supervisor mode during Functional access
and CPSW will stop functioning.
Hence, fix it by moving pm_runtime_get_sync() before the first access
to CPSW registers in cpsw_ndo_open().

Assuming SOF_TIMESTAMPING_TX_ACK is on. When dup acks are received,
it could incorrectly think that a skb has already
been acked and queue a SCM_TSTAMP_ACK cmsg to the
sk->sk_error_queue.
In tcp_ack_tstamp(), it checks
'between(shinfo->tskey, prior_snd_una, tcp_sk(sk)->snd_una - 1)'.
If prior_snd_una == tcp_sk(sk)->snd_una like the following packetdrill
script, between() returns true but the tskey is actually not acked.
e.g. try between(3, 2, 1).
The fix is to replace between() with one before() and one !before().
By doing this, the -1 offset on the tcp_sk(sk)->snd_una can also be
removed.
A packetdrill script is used to reproduce the dup ack scenario.
Due to the lacking cmsg support in packetdrill (may be I
cannot find it), a BPF prog is used to kprobe to
sock_queue_err_skb() and print out the value of
serr->ee.ee_data.
Both the packetdrill and the bcc BPF script is attached at the end of
this commit message.

This is the IPv6 counterpart to commit 8282f27449bf ("inet: frag: Always
orphan skbs inside ip_defrag()").
Prior to commit 029f7f3b8701 ("netfilter: ipv6: nf_defrag: avoid/free
clone operations"), ipv6 fragments sent to nf_ct_frag6_gather() would be
cloned (implicitly orphaning) prior to queueing for reassembly. As such,
when the IPv6 message is eventually reassembled, the skb->sk for all
fragments would be NULL. After that commit was introduced, rather than
cloning, the original skbs were queued directly without orphaning. The
end result is that all frags except for the first and last may have a
socket attached.
This commit explicitly orphans such skbs during nf_ct_frag6_gather() to
prevent BUG_ON(skb->sk) during a later call to ip6_fragment().
kernel BUG at net/ipv6/ip6_output.c:631!
