 "Device tree Exynos bug fix for v3.16-rc7

  This bug fix has been brewing for a while.  I hate sending it to you
  so late, but I only got confirmation that it solves the problem this
  past weekend.  The diff looks big for a bug fix, but the majority of
  it is only executed in the Exynos quirk case.  Unfortunately it
  required splitting early_init_dt_scan() in two and adding quirk
  handling in the middle of it on ARM.

  Exynos has buggy firmware that puts bad data into the memory node.
  Commit 1c2f87c2 ("ARM: Get rid of meminfo") exposed the bug by
  dropping the artificial upper bound on the number of memory banks that
  can be added.  Exynos fails to boot after that commit.  This branch
  fixes it by splitting the early DT parse function and inserting a
  fixup hook.  Exynos uses the hook to correct the DT before parsing
  memory regions"

      x86/xen: safely map and unmap grant frames when in atomic context · b7dd0e35
      David Vrabel authored 
      arch_gnttab_map_frames() and arch_gnttab_unmap_frames() are called in
atomic context but were calling alloc_vm_area() which might sleep.

Also, if a driver attempts to allocate a grant ref from an interrupt
and the table needs expanding, then the CPU may already by in lazy MMU
mode and apply_to_page_range() will BUG when it tries to re-enable
lazy MMU mode.

These two functions are only used in PV guests.

Introduce arch_gnttab_init() to allocates the virtual address space in
advance.

Avoid the use of apply_to_page_range() by using saving and using the
array of PTE addresses from the alloc_vm_area() call (which ensures
that the required page tables are pre-allocated).

      kvm: arm64: vgic: fix hyp panic with 64k pages on juno platform · 63afbe7a
      Will Deacon authored 
      If the physical address of GICV isn't page-aligned, then we end up
creating a stage-2 mapping of the page containing it, which causes us to
map neighbouring memory locations directly into the guest.

As an example, consider a platform with GICV at physical 0x2c02f000
running a 64k-page host kernel. If qemu maps this into the guest at
0x80010000, then guest physical addresses 0x80010000 - 0x8001efff will
map host physical region 0x2c020000 - 0x2c02efff. Accesses to these
physical regions may cause UNPREDICTABLE behaviour, for example, on the
Juno platform this will cause an SError exception to EL3, which brings
down the entire physical CPU resulting in RCU stalls / HYP panics / host
crashing / wasted weeks of debugging.

SBSA recommends that systems alias the 4k GICV across the bounding 64k
region, in which case GICV physical could be described as 0x2c020000 in
the above scenario.

This patch fixes the problem by failing the vgic probe if the physical
base address or the size of GICV aren't page-aligned. Note that this
generated a warning in dmesg about freeing enabled IRQs, so I had to
move the IRQ enabling later in the probe.

      arm: Add devicetree fixup machine function · 5a12a597
      Laura Abbott authored 
      Commit 1c2f87c2
(ARM: 8025/1: Get rid of meminfo) dropped the upper bound on
the number of memory banks that can be added as there was no
technical need in the kernel. It turns out though, some bootloaders
(specifically the arndale-octa exynos boards) may pass invalid memory
information and rely on the kernel to not parse this data. This is a
bug in the bootloader but we still need to work around this.
Work around this by introducing a dt_fixup function. This function
gets called before the flattened devicetree is scanned for memory
and the like. In this fixup function for exynos, limit the maximum
number of memory regions in the devicetree.

boot params, and scans for chosen/memory all in one function.
Split this up into two separate functions (validation/setting
boot params in one, scanning in another) to allow for
additional setup between boot params and scanning the memory.

      net: phy: re-apply PHY fixups during phy_register_device · d92f5dec
      Florian Fainelli authored 
      Commit 87aa9f9c ("net: phy: consolidate PHY reset in phy_init_hw()")
moved the call to phy_scan_fixups() in phy_init_hw() after a software
reset is performed.

By the time phy_init_hw() is called in phy_device_register(), no driver
has been bound to this PHY yet, so all the checks in phy_init_hw()
against the PHY driver and the PHY driver's config_init function will
return 0. We will therefore never call phy_scan_fixups() as we should.

Fix this by calling phy_scan_fixups() and check for its return value to
restore the intended functionality.

This broke PHY drivers which do register an early PHY fixup callback to
intercept the PHY probing and do things like changing the 32-bits unique
PHY identifier when a pseudo-PHY address has been used, as well as
board-specific PHY fixups that need to be applied during driver probe
time.

This reports means that we've come to netlink_sendmsg() with msg->msg_name == NULL and msg->msg_namelen > 0.

After this report there was no usual "Unable to handle kernel NULL pointer dereference"
and this gave me a clue that address 0 is mapped and contains valid socket address structure in it.

This bug was introduced in f3d33426
(net: rework recvmsg handler msg_name and msg_namelen logic).
Commit message states that:
	"Set msg->msg_name = NULL if user specified a NULL in msg_name but had a
	 non-null msg_namelen in verify_iovec/verify_compat_iovec. This doesn't
	 affect sendto as it would bail out earlier while trying to copy-in the
	 address."
But in fact this affects sendto when address 0 is mapped and contains
socket address structure in it. In such case copy-in address will succeed,
verify_iovec() function will successfully exit with msg->msg_namelen > 0
and msg->msg_name == NULL.

This patch fixes it by setting msg_namelen to 0 if msg_name == NULL.

      Commit 9188883f (ARM: dts: Enable twl4030 off-idle configuration

vaux1 was not getting enabled for the LCD panel as we are not
requesting it for the panel.

Turns out quite a few devices on n900 are using vaux1, and we need
to either stop idling it, or add proper regulator_get calls for all
users. But until we have a proper solution implemented and tested,
let's just disable the twl off-idle configuration for now for n900.

Jedidiah describe ways exploiting linux IP identifier generation to
infer whether two machines are exchanging packets.

With commit 73f156a6 ("inetpeer: get rid of ip_id_count"), we
changed IP id generation, but this does not really prevent this
side-channel technique.

This patch adds a random amount of perturbation so that IP identifiers
for a given destination [1] are no longer monotonically increasing after
an idle period.

Note that prandom_u32_max(1) returns 0, so if generator is used at most
once per jiffy, this patch inserts no hole in the ID suite and do not
increase collision probability.

This is jiffies based, so in the worst case (HZ=1000), the id can
rollover after ~65 seconds of idle time, which should be fine.

We also change the hash used in __ip_select_ident() to not only hash
on daddr, but also saddr and protocol, so that ICMP probes can not be
used to infer information for other protocols.

For IPv6, adds saddr into the hash as well, but not nexthdr.

If I ping the patched target, we can see ID are now hard to predict.

21:57:11.008086 IP (...)
    A > target: ICMP echo request, seq 1, length 64
21:57:11.010752 IP (... id 2081 ...)
    target > A: ICMP echo reply, seq 1, length 64

21:57:12.013133 IP (...)
    A > target: ICMP echo request, seq 2, length 64
21:57:12.015737 IP (... id 3039 ...)
    target > A: ICMP echo reply, seq 2, length 64

21:57:13.016580 IP (...)
    A > target: ICMP echo request, seq 3, length 64
21:57:13.019251 IP (... id 3437 ...)
    target > A: ICMP echo reply, seq 3, length 64

[1] TCP sessions uses a per flow ID generator not changed by this patch.

      neighbour : fix ndm_type type error issue · 545469f7
      Jun Zhao authored 
      ndm_type means L3 address type, in neighbour proxy and vxlan, it's RTN_UNICAST.
NDA_DST is for netlink TLV type, hence it's not right value in this context.

      sunvnet: only use connected ports when sending · 8266f5fc
      David L Stevens authored 
      The sunvnet driver doesn't check whether or not a port is connected when
transmitting packets, which results in failures if a port fails to connect
(e.g., due to a version mismatch). The original code also assumes
unnecessarily that the first port is up and a switch, even though there is
a flag for switch ports.

This patch only matches a port if it is connected, and otherwise uses the
switch_port flag to send the packet to a switch port that is up.

====================
pull-request: can 2014-07-25

this is a pull request of one patch for the net tree, hoping to get into the
3.16 release.

The patch by George Cherian fixes a regression in the c_can platform driver.
When using two interfaces the regression leads to a non function second
interface.
