303bc93472 ARM: SoC fixes for v5.10, part 3
Another set of patches for devicetree files and Arm
 SoC specific drivers:
 
  - A fix for OP-TEE shared memory on non-SMP systems
 
  - multiple code fixes for the OMAP platform, including
    one regression for the CPSW network driver and a few
    runtime warning fixes
 
  - Some DT patches for the Rockchip RK3399 platform,
    in particular fixing the MMC device ordering that
    recently became nondeterministic with async probe.
 
  - Multiple DT fixes for the Tegra platform, including
    a regression fix for suspend/resume on TX2
 
  - A regression fix for a user-triggered fault in the
    NXP dpio driver
 
  - A regression fix for a bug caused by an earlier bug
    fix in the xilinx firmware driver
 
  - Two more DTC warning fixes
 
  - Sylvain Lemieux steps down as maintainer for the
    NXP LPC32xx platform

76dc2bfc2e Raw NAND changes:
* Because of a recent change in the core, NAND controller drivers
   initializing the ECC engine too early in the probe path are
   broken. Drivers should wait for the NAND device to be discovered and
   its memory layout known before doing any ECC related initialization,
   so instead of reverting the faulty change which is actually moving
   in the right direction, let's fix the drivers directly: socrates,
   sharpsl, r852, plat_nand, pasemi, tmio, txx9ndfmc, orion, mpc5121,
   lpc32xx_slc, lpc32xx_mlc, fsmc, diskonchip, davinci, cs553x, au1550,

 "Because of a recent change in the core, NAND controller drivers
  initializing the ECC engine too early in the probe path are broken.

  Drivers should wait for the NAND device to be discovered and its

  The vc4 fixes are a few but they are fixes and the nastiest one is a
  fix for when you have a 2.4Ghz Wifi and a HDMI signal with a clock in
  that range and there isn't enough shielding and interference happen
  between the two, the fix adjusts the mode clock to try and avoid the

====================
pull-request: can 2020-11-27

The first patch is by me and target the gs_usb driver and fixes the endianess
problem with candleLight firmware.

Another patch by me for the mcp251xfd driver add sanity checking to bail out if
no IRQ is configured.

The next three patches target the m_can driver. A patch by me removes the
hardcoded IRQF_TRIGGER_FALLING from the request_threaded_irq() as this clashes
with the trigger level specified in the DT. Further a patch by me fixes the
nominal bitiming tseg2 min value for modern m_can cores. Pankaj Sharma's patch
add support for cores version 3.3.x.

The last patch by Oliver Hartkopp is for af_can and converts a WARN() into a
pr_warn(), which is triggered by the syzkaller. It was able to create a
situation where the closing of a socket runs simultaneously to the notifier
call chain for removing the CAN network device in use.

985f733742 sock: set sk_err to ee_errno on dequeue from errq
When setting sk_err, set it to ee_errno, not ee_origin.

Commit f5f99309fa ("sock: do not set sk_err in
sock_dequeue_err_skb") disabled updating sk_err on errq dequeue,
which is correct for most error types (origins):

  -       sk->sk_err = err;

Commit 38b257938a ("sock: reset sk_err when the error queue is
empty") reenabled the behavior for IMCP origins, which do require it:

  +       if (icmp_next)
  +               sk->sk_err = SKB_EXT_ERR(skb_next)->ee.ee_origin;

But read from ee_errno.

d3ab78858f mptcp: fix NULL ptr dereference on bad MPJ
If an msk listener receives an MPJ carrying an invalid token, it
will zero the request socket msk entry. That should later
cause fallback and subflow reset - as per RFC - at
subflow_syn_recv_sock() time due to failing hmac validation.

Since commit 4cf8b7e48a ("subflow: introduce and use
mptcp_can_accept_new_subflow()"), we unconditionally dereference
- in mptcp_can_accept_new_subflow - the subflow request msk
before performing hmac validation. In the above scenario we
hit a NULL ptr dereference.

Address the issue doing the hmac validation earlier.

69929d4c49 net: openvswitch: fix TTL decrement action netlink message format
Currently, the openvswitch module is not accepting the correctly formated
netlink message for the TTL decrement action. For both setting and getting
the dec_ttl action, the actions should be nested in the
OVS_DEC_TTL_ATTR_ACTION attribute as mentioned in the openvswitch.h uapi.

When the original patch was sent, it was tested with a private OVS userspace
implementation. This implementation was unfortunately not upstreamed and
reviewed, hence an erroneous version of this patch was sent out.

Leaving the patch as-is would cause problems as the kernel module could
interpret additional attributes as actions and vice-versa, due to the
actions not being encapsulated/nested within the actual attribute, but
being concatinated after it.

9a2a0d3ca1 kvm: x86/mmu: Fix get_mmio_spte() on CPUs supporting 5-level PT
Commit 95fb5b0258 ("kvm: x86/mmu: Support MMIO in the TDP MMU") caused
the following WARNING on an Intel Ice Lake CPU:

 get_mmio_spte: detect reserved bits on spte, addr 0xb80a0, dump hierarchy:

 WARNING: CPU: 109 PID: 10254 at arch/x86/kvm/mmu/mmu.c:3569 kvm_mmu_page_fault.cold.150+0x54/0x22f [kvm]

  kvm_arch_vcpu_ioctl_run+0xca/0x520 [kvm]

The guest triggering this crashes. Note, this happens with the traditional
MMU and EPT enabled, not with the newly introduced TDP MMU. Turns out,
there was a subtle change in the above mentioned commit. Previously,
walk_shadow_page_get_mmio_spte() was setting 'root' to 'iterator.level'
which is returned by shadow_walk_init() and this equals to
'vcpu->arch.mmu->shadow_root_level'. Now, get_mmio_spte() sets it to
'int root = vcpu->arch.mmu->root_level'.

The difference between 'root_level' and 'shadow_root_level' on CPUs
supporting 5-level page tables is that in some case we don't want to
use 5-level, in particular when 'cpuid_maxphyaddr(vcpu) <= 48'
kvm_mmu_get_tdp_level() returns '4'. In case upper layer is not used,
the corresponding SPTE will fail '__is_rsvd_bits_set()' check.

Revert to using 'shadow_root_level'.

71cc849b70 KVM: x86: Fix split-irqchip vs interrupt injection window request
kvm_cpu_accept_dm_intr and kvm_vcpu_ready_for_interrupt_injection are
a hodge-podge of conditions, hacked together to get something that
more or less works.  But what is actually needed is much simpler;
in both cases the fundamental question is, do we have a place to stash
an interrupt if userspace does KVM_INTERRUPT?

In userspace irqchip mode, that is !vcpu->arch.interrupt.injected.
Currently kvm_event_needs_reinjection(vcpu) covers it, but it is
unnecessarily restrictive.

In split irqchip mode it's a bit more complicated, we need to check
kvm_apic_accept_pic_intr(vcpu) (the IRQ window exit is basically an INTACK
cycle and thus requires ExtINTs not to be masked) as well as
!pending_userspace_extint(vcpu).  However, there is no need to
check kvm_event_needs_reinjection(vcpu), since split irqchip keeps
pending ExtINT state separate from event injection state, and checking
kvm_cpu_has_interrupt(vcpu) is wrong too since ExtINT has higher
priority than APIC interrupts.  In fact the latter fixes a bug:
when userspace requests an IRQ window vmexit, an interrupt in the
local APIC can cause kvm_cpu_has_interrupt() to be true and thus
kvm_vcpu_ready_for_interrupt_injection() to return false.  When this
happens, vcpu_run does not exit to userspace but the interrupt window
vmexits keep occurring.  The VM loops without any hope of making progress.

Once we try to fix these with something like

     return kvm_arch_interrupt_allowed(vcpu) &&
-        !kvm_cpu_has_interrupt(vcpu) &&
-        !kvm_event_needs_reinjection(vcpu) &&
-        kvm_cpu_accept_dm_intr(vcpu);
+        (!lapic_in_kernel(vcpu)
+         ? !vcpu->arch.interrupt.injected
+         : (kvm_apic_accept_pic_intr(vcpu)
+            && !pending_userspace_extint(v)));

we realize two things.  First, thanks to the previous patch the complex
conditional can reuse !kvm_cpu_has_extint(vcpu).  Second, the interrupt
window request in vcpu_enter_guest()

        bool req_int_win =
                dm_request_for_irq_injection(vcpu) &&
                kvm_cpu_accept_dm_intr(vcpu);

should be kept in sync with kvm_vcpu_ready_for_interrupt_injection():
it is unnecessary to ask the processor for an interrupt window
if we would not be able to return to userspace.  Therefore,
kvm_cpu_accept_dm_intr(vcpu) is basically !kvm_cpu_has_extint(vcpu)
ANDed with the existing check for masked ExtINT.  It all makes sense:

- we can accept an interrupt from userspace if there is a place
  to stash it (and, for irqchip split, ExtINTs are not masked).
  Interrupts from userspace _can_ be accepted even if right now
  EFLAGS.IF=0.

- in order to tell userspace we will inject its interrupt ("IRQ
  window open" i.e. kvm_vcpu_ready_for_interrupt_injection), both
  KVM and the vCPU need to be ready to accept the interrupt.

... and this is what the patch implements.

72c3bcdcda KVM: x86: handle !lapic_in_kernel case in kvm_cpu_*_extint
Centralize handling of interrupts from the userspace APIC
in kvm_cpu_has_extint and kvm_cpu_get_extint, since
userspace APIC interrupts are handled more or less the
same as ExtINTs are with split irqchip.  This removes
duplicated code from kvm_cpu_has_injectable_intr and
kvm_cpu_has_interrupt, and makes the code more similar
between kvm_cpu_has_{extint,interrupt} on one side
and kvm_cpu_get_{extint,interrupt} on the other.

d73ff9b7c4 can: af_can: can_rx_unregister(): remove WARN() statement from list operation sanity check
To detect potential bugs in CAN protocol implementations (double removal of
receiver entries) a WARN() statement has been used if no matching list item was
found for removal.

The fault injection issued by syzkaller was able to create a situation where
the closing of a socket runs simultaneously to the notifier call chain for
removing the CAN network device in use.

This case is very unlikely in real life but it doesn't break anything.
Therefore we just replace the WARN() statement with pr_warn() to preserve the
notification for the CAN protocol development.

e3409e4192 can: m_can: fix nominal bitiming tseg2 min for version >= 3.1
At lest the revision 3.3.0 of the bosch m_can IP core specifies that valid
register values for "Nominal Time segment after sample point (NTSEG2)" are from
1 to 127. As the hardware uses a value of one more than the programmed value,
mean tseg2_min is 2.

This patch fixes the tseg2_min value accordingly.

865f5b671b can: m_can: m_can_open(): remove IRQF_TRIGGER_FALLING from request_threaded_irq()'s flags
The threaded IRQ handler is used for the tcan4x5x driver only. The IRQ pin of
the tcan4x5x controller is active low, so better not use IRQF_TRIGGER_FALLING
when requesting the IRQ. As this can result in missing interrupts.

Further, if the device tree specified the interrupt as "IRQ_TYPE_LEVEL_LOW",
unloading and reloading of the driver results in the following error during
ifup:

| irq: type mismatch, failed to map hwirq-31 for gpio@20a8000!
| tcan4x5x spi1.1: m_can device registered (irq=0, version=32)
| tcan4x5x spi1.1 can2: TCAN4X5X successfully initialized.
| tcan4x5x spi1.1 can2: failed to request interrupt

This patch fixes the problem by removing the IRQF_TRIGGER_FALLING from the
request_threaded_irq().

4df910620b mm: memcg: relayout structure mem_cgroup to avoid cache interference
0day reported one -22.7% regression for will-it-scale page_fault2
case [1] on a 4 sockets 144 CPU platform, and bisected to it to be
caused by Waiman's optimization (commit bd0b230fe1) of saving one
'struct page_counter' space for 'struct mem_cgroup'.

Initially we thought it was due to the cache alignment change introduced
by the patch, but further debug shows that it is due to some hot data
members ('vmstats_local', 'vmstats_percpu', 'vmstats') sit in 2 adjacent
cacheline (2N and 2N+1 cacheline), and when adjacent cache line prefetch
is enabled, it triggers an "extended level" of cache false sharing for
2 adjacent cache lines.

So exchange the 2 member blocks, while keeping mostly the original
cache alignment, which can restore and even enhance the performance,
and save 64 bytes of space for 'struct mem_cgroup' (from 2880 to 2816,
with 0day's default RHEL-8.3 kernel config)

af60470347 io_uring: fix files grab/cancel race
When one task is in io_uring_cancel_files() and another is doing
io_prep_async_work() a race may happen. That's because after accounting
a request inflight in first call to io_grab_identity() it still may fail
and go to io_identity_cow(), which migh briefly keep dangling
work.identity and not only.

Grab files last, so io_prep_async_work() won't fail if it did get into
->inflight_list.

note: the bug shouldn't exist after making io_uring_cancel_files() not
poking into other tasks' requests.
